  • High vacuum welding fume dust collector --Suitable for robot arc welding and laser welding Small in size, strong in suction, and strong in continuous operation, it is a very suitable equipment for manipulator welding torch nozzle smoking. It can be hung on the portal robot to move with the robot. Correspondingly, a set of small suction nozzles or sleeves are installed on the robot welding gun according to the welding process and working conditions, and a small suction nozzle or sleeve is installed to smoke with the welding gun. Connect the suction nozzle sleeve above the welding gun of the robot through the suction hose. The hose can be arranged together with the cable. The design of the nozzle sleeve needs to be designed according to the structure of the welding gun, the welding characteristic shape of the workpiece, and the welding angle. Any product has its limitations, because it is limited by the welding station, fixture design, and welding torch posture, it cannot be used in all welding conditions.
  • For the welding of robots and special machines, each robot station can be separated, an independent welding room or suction hood can be designed, and the fumes generated during welding in each welding room or suction hood can be collected and managed by a unified system. The road is connected to each welding room or suction hood, and is fed into the dust collector for centralized purification treatment, and finally the purified air is discharged into the atmosphere through a unified exhaust port. The smoke and dust generated by each welding station can be effectively absorbed, will not pollute other parts of the workshop, and play the greatest role in protecting the health of employees. ● The model of the dust removal equipment is selected according to the size and quantity of the suction hood and the workshop ● Explosion-proof measures need to be considered when welding aluminum, magnesium and other alloy materials ● When the welding workpiece contains oil, the dust removal equipment needs to add a pretreatment device ● Frequency conversion control can be used when the power of the dust removal system is large
  • The welding workshop of construction machinery, fixture and other large, heterogeneous workpieces has a huge span, and the workshop is long, and the welding station is not fixed; the workpieces are hoisted by crane. The dust removal system shall not affect the production efficiency. Considering that the welding station is not fixed and the workpiece is relatively large, the dust removal method shall not affect the workpiece hoisting and the worker's production efficiency, Therefore, we suggest to adopt the blowing suction centralized dust removal mode, which is based on the user's needs and the design principle of meeting the production process requirements, It is mainly considered from the working environment, atmospheric emission standard, reliable operation of equipment, convenient operation and maintenance, etc, Try our best to provide the best and most economical dust control scheme. Introduction to the purification principle of the blowing and suction system: The smoke-blowing dust purifier is equipped with air duct return air outlets and air supply outlets, and its return air outlet distribution and laying position are located at the dense height of smoke and dust gathering (4-7 meters, the height of the welding point is different, and the height of the dust density is also different). After filtering and meeting the indoor circulation standard, the air inlet and exhaust pipes reach the air supply outlet, and are sent to the smoke and dust purification system that continuously circulates at the same floor height---the blowing smoke dust purification system. The collection of harmful smoke and dust in dense areas of the same height is highly efficient; the use of high-efficiency filters, the filtration accuracy fully meets the indoor emission standards, and the filtration efficiency reaches 99.9%, which effectively improves the working area environment; Because the collection of smoke and dust is not directly aimed at the smoke-producing part, the dust removal system is not affected by the size of the welding workpiece, and is not affected by the change of the welding station; completely solve the problem of dust purification and will not cause secondary pollution to the atmosphere; The two devices are used together to form a perfect blowing and suction purification system, the required air volume is only half of the traditional mixed air supply form, and the operating energy consumption is greatly reduced; Because the smoke and dust can reach the indoor emission standard after filtering, the indoor air can be circulated to avoid the waste of indoor cold/heat energy caused by external exhaust; The dust removal system is not affected by the operator's habits, and the operator is not affected by any interference from the dust removal system during the work process, which can greatly improve production efficiency
  • What are the hazards of dust dust in welding workshop (1) Generation of welding fume Welding is the use of electric energy heating, so that the metal material to be welded locally to liquid or near liquid, and make it fusion to form a stable non detachable connector processing technology. When the electrode melts at high temperature and reaches the boiling point, the generated high-temperature steam will quickly oxidize and condense into fine solid dispersed particles as soon as it leaves the welding high-temperature zone, floating in the air to form welding dust. (2) Composition of welding fume The chemical composition of welding fume lies in the composition of welding materials (welding wire, welding rod, flux, etc.). )And welding material and its evaporation difficulty. Welding materials and different components of welding materials will produce different components of welding dust in the welding process. Method and application of welding dust removal in workshop Whether it is the workshop welding dust or to protect the health of workers, the installation of dust removal equipment is a better way. The actual effect of different dust removal methods is different. Here are some common workshop welding dust removal process and equipment. Workshop welding dust purifier: The purification of welding dust remover in workshop is a common dust removal method in station. The welding dust remover in workshop is different from the ordinary station dust remover. When cleaning the dust, the welding dust purifier can absorb the welding dust produced by a single station into the internal filtering system of the dust collector, and the filtered clean air is discharged to the production workshop again, and the dust is stored in the dust drawer. The movable welding fume purifier is composed of purifier, suction arm and suction cover. Design principle of workshop welding dust purifier: when the fan is running, the flue gas enters the dust removal equipment from the air inlet, forcing the air flow in the dust removal equipment to change the wind direction and reduce the flow rate. When the flue gas passes through the filter cartridge with the air flow, it is filtered by the filter cartridge and blocked on its surface. The purified gas rises from the filter cartridge to the middle cartridge and is filtered by the fan and then discharged from the air outlet through the activated carbon filter cotton. When there is more smoke on the surface of the filter cartridge, the pulse switch opens and the pulse injection controller starts to work. The electromagnetic pulse valve works so that the compressed air in the air bag can be injected into the filter cartridge at high speed through the nozzle, and at the same time, the surrounding air which is several times of the injected air can be induced to enter the filter cartridge, resulting in the instantaneous positive pressure in the filter cartridge, so that the dust accumulated on the surface of the filter cartridge falls into the ash hopper under the action of gravity, and the dust in the ash hopper can be cleaned after the equipment stops running.
  • The closed cover of the dust removal equipment manufacturer encloses all the pollution sources, limits the spread of harmful substances in a small enclosed space, and uses enough exhaust pans to generate negative pressure in the cover to ensure that harmful substances are not removed from certain Escape from orifices and crevices. Some equipment itself is airtight, just connect the exhaust pipe as required, such as trommel screen, cleaning roller, etc. According to the installation form, the airtight cover is divided into two types: fixed and mobile. For example, the airtight cover of the old belt conveyor is fixed, and the airtight cover of the large sand shaker is mobile. According to the degree of airtightness, the airtight cover is divided into three types: partial airtight cover, overall airtight cover, and large volume airtight chamber. Partial airtight cover is to partially airtight the dust point of the equipment, and the process equipment is exposed outside the airtight cover. For example, the blanking point of a belt conveyor. The volume of the local airtight cover is small, which is suitable for dust sources with small dust-generating airflow speed, concentrated, continuous dust and low instantaneous pressure increase. The integral airtight cover is to seal most of the equipment or places that generate dust, and only the transmission part of the equipment is left outside the cover. For example, the integral airtight cover of the rolling screen is suitable for large mechanical vibration, large dust area and high dust-producing air velocity. The source of dust. Large-volume airtight chamber is to seal all the equipment or places that generate dust, such as a vibrating screen airtight chamber. The airtight chamber has a large volume, which can buffer dust-containing airflow and reduce local positive pressure. It is suitable for many dust points, dust area and dust-generating airflow. Equipment with high speed and frequent maintenance or regular replacement of parts and components.

  • Dust explosion-When combustible dust suspended in the air touches a fire source such as an open flame or electric spark, it releases a large amount of energy, generates high temperature, and releases a large amount of gas in a very short time, causing a high-pressure chemical reaction in the surrounding medium. To avoid combustible dust explosion, we can start from the following two points: one is to control the concentration of combustible dust in the workshop, and the other is to eliminate fire on the spot. Regarding the second point, the elimination of on-site fires, fireworks, regular inspections of wires and lines, etc. must be strictly prohibited in the workshop to cultivate the safety knowledge of each employee. The concentration of combustible dust in the workshop must be controlled at the same time: each dust production point is equipped with a dust suction device, the negative pressure and air volume of the dust suction port should meet the actual working conditions, the explosion-proof dust collector, advanced and effective automatic Dust removal device, anti-static filter cartridge, timely cleaning of accumulated dust, installation of combustible dust concentration alarm, etc. 1. Use explosion-proof electrical control cabinet to avoid arc ignition when starting. 2. Install an explosion vent on the shell of the dust removal equipment to prevent dust explosion from damaging the dust removal equipment and other equipment in the plant. 3. The filter cartridge uses explosion-proof coated polyester fiber filter cartridge 4. The principle of filter cartridge cleaning: The pneumatic pulse blowback system consists of an air bag, electromagnetic pulse valve, PLC controller, and compressed air. One end of the pulse valve is connected to a compressed air tank, and the other end is connected to a spray device. An exhaust valve is installed on the valve cover, and the exhaust valve is controlled by a PLC pulse controller. When there is no signal from the PLC controller, the movable baffle of the exhaust valve is in the position of closing the exhaust hole; when the program controller sends a signal, the movable baffle opens, and the compressed air in the air storage tank is quickly released from pressure, so the exhaust The corrugated membrane inside the valve is pressed in the opposite direction, the jet port is opened, and the compressed air enters the filter cartridge through the pulse valve for blowing and cleaning. When the signal disappears, the movable baffle returns to the original position of closing the exhaust valve, and the corrugated membrane is closed again At the air jet port, the blowing stops automatically. Each time the blowing and cleaning is completed in about 0.1~0.3S, it is the high-pressure air sprayed at this moment that has a good cleaning effect. The air enters the filter cartridge at a higher flow rate, causing the air in the filter cartridge to expand rapidly, causing a shock vibration, so that the dust attached to the outer surface of the filter cartridge is shaken off, and the dust adsorbed on the surface of the filter material shakes off to the collection under the action of the airflow. In the dust box. The pulse blowing air pressure is 0.4~0.6MPa, and the air supply must be kept constant during operation. The filter cartridge is automatically cleaned in turn on a regular basis. When the filter cartridge is cleaned, it will not affect the normal operation of the equipment and system. The smoke and dust fall into the ash bucket through the dust bucket and are cleaned regularly. 5. The solenoid valve uses explosion-proof solenoid valve to avoid arc ignition when starting. 6. Use explosion-proof motors to avoid arc ignition during startup. 7. The centrifugal fan has explosion-proof function 7.1. The impeller inside the centrifugal fan is made of aluminum alloy to avoid sparks when dust particles rub against the impeller. 7.2. The ferrule at the suction port of the centrifugal fan is made of copper ferrule to avoid sparks when the inlet dust enters the centrifugal fan. 8. Install explosion venting plate for ventilation and dust removal pipe In order to prevent dust particles from exploding after being deposited inside the main ventilation and dust removal pipeline, it is necessary to install an explosion venting plate every 3 meters on the main ventilation and dust removal official road during the dust removal design. The explosion venting plate has the function of feeding back electrical signals. , When the explosion vent plate vents the explosion, an electrical signal will be sent to the electrical control part of the smoke and dust purifier. The electrical control part will cause the centrifugal fan inside the smoke and dust purification to stop through the PLC to protect the entire smoke and dust purification system. Applicable industry: 1. Dust management in the pharmaceutical industry 2. Explosion-proof treatment of aluminum alloy dust 3. Explosion-proof treatment of cement dust, wood dust, plastic dust

During the grinding process, a large amount of dust (abrasives of the grinding wheel, fibers and particles of the cloth wheel with a shaft), metal shavings (carbon steel, stainless steel, lead, copper) and other harmful substances and harsh noise will be generated, because the ordinary grinding room does not have dust removal Noise reduction function, in order to reduce the pollution of the grinding operation to the production environment, many companies have adopted different methods, but the effect is not satisfactory. For the analysis and combination of the principles of noise reduction and dust removal, a new concept of noise reduction and dust removal is adopted, which better solves these two problems. Grinding table: suitable for small workpieces, flat workpieces, grinding, polishing, engraving and dust removal, combined with side suction and under-table suction. Grinding room: suitable for large and small workpieces, irregular workpieces, heavy workpieces, side suction cabinet type dust removal Grinding and dust collection series: explosion-proof motor fan and explosion-proof switch can be added. Put the workpiece on the worktable and polish it. Under the suction action of the exhaust fan, suck the dust and dust from the workpiece into the machine. The polished dust will not stay in the operator's breathing area, but will follow the ventilation. The airflow is quickly drawn into the mainframe, and the airflow with dust flows out of the machine through the filter cartridge filter system. The larger dust particles are filtered by the cloth bag and fall into the integrated box of the mainframe, which greatly improves the working environment.
  • I. Overview In modern industrial production, flame cutting will produce a lot of smoke and dust when cutting steel plates. The smoke and dust are sprayed from below the workpiece and distributed in the workshop, causing the workshop to be filled with smoke and dust.
