The role of dust removal equipment airtight cover
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.
