Design of Dust Cover in Dust Collection System

The gas collecting hood is a device to control the dust laden airflow and collect dust. It is an important part of the local ventilation and dust removal system. The function of the gas collecting hood is to collect the smoke and dust emitted from the dust source and lead it into the purification system to prevent it from spreading to the production workshop and the atmosphere and causing pollution. If the form and location are selected reasonably, the better dust removal effect can be obtained by using small exhaust air volume.

Due to the different production process conditions and operation modes, the gas collecting hood can be divided into various forms.

The proper design of the integrated cover directly affects the dust collection effect of the Dust Collector. The air collecting and dust collecting hood is a device for controlling dust laden air flow and collecting dust.

1. Electric rotating dust collecting hood

Manual welding station is relatively centralized, using one machine multi station mode. Considering the convenience of lifting the workpiece, the rotary dust collecting cover is used to collect dust.

The cantilever can swing freely around the fixed column and hover in the range of 180 ° under the action of swing angle motor. In this system, the swing angle mechanism adopts gear meshing mode to transmit swing angle power, which has the advantages of high transmission efficiency, stable operation and long service life.

2. Pneumatic translation dust hood

Welding will produce a large number of smoke and gas rising characteristics, in the upper part of the welding workers set dust cover, using the negative pressure generated by the fan to collect the smoke gas into the air duct, and then use the smoke purification device to purify and discharge up to standard.

The dust collecting mechanism of translational top suction dust collecting cover can extend and retract horizontally driven by driving cylinder.

3. Fixed dust hood

The top Suction Hood is suitable for welding dust removal with fixed welding station. The shape of the top suction hood is quadrangle platform, and the included angle between each side and the ground is not less than 45 degrees. In order to avoid the interference of transverse air flow, arc curtain can be hung on the side of the suction hood. Workers can weld freely within the scope covered by the hood, and the smoke and dust generated can be captured and purified smoothly!

4. Manually rotate the dust hood

Compared with the electric rotating cover and the pneumatic translation cover, the manual rotating cover has lower cost and lower cost, which not only does not delay the traveling crane to get up and down the workpiece, but also reduces the air volume and investment.
