Powder spraying room industrial flange top square cover dust collector filter element

The filter element of the square cover dust collector on the top of the industrial flange in the powder coating room is the core filtering component of the dust removal system for the powder coating production line. It is specially designed for the top mounted dust removal unit of the spraying room to capture the powder coating particles that float and overflow during the spraying operation, avoiding incomplete adhesion of powder and directly discharging them into the outside, causing raw material waste and environmental dust accumulation. It is a key filtering element to ensure the cleanliness of the air in the powder coating workshop and improve the recycling rate of powder coating. It is compatible with various conventional top mounted square chuck dust removal equipment and can directly replace the original filter element of the same specification without the need for additional adjustment of the dust removal system structure.

The dust collector filter element of the powder spraying room is designed with a square flange end cover on the top of the industrial flange. The end cover is embedded with a whole circle of heat-resistant sealing rubber ring inside, which can be directly attached to the square installation plate on the top of the spraying room during installation, preventing dust from leaking through the interface; The filter body is made of high porosity polyester coated filter material, which is formed into a large filtering area structure through uniform folding process. The internal structure is equipped with thickened galvanized metal support skeleton, which has higher overall deformation resistance strength; The surface of the coating layer is smooth and dense, making it difficult for powder dust to embed into the fibers of the filter material. During pulse cleaning, the dust can be completely peeled off without the common problem of "powder paste blockage" in ordinary filter materials. The overall structure is suitable for the installation condition of vertical installation on the top of the spraying room, and can maintain stable filtering performance even in high concentration powder environments for a long time.

This powder spraying room industrial flange top square cover dust collector filter element is widely suitable for dust removal and filtration scenarios in various powder spraying production lines. It can be used in the top dust removal unit of hardware spraying line spraying room, building material profile powder recovery system, craft electrostatic spraying dust purification, metal component powder spraying workshop air circulation filtration and other working conditions. It is especially suitable for continuous operation spraying production lines with high concentration of epoxy powder and polyester powder dispersion. It can effectively intercept more than 99% of spilled powder particles, greatly reducing the pressure of subsequent exhaust gas treatment. At the same time, the recovered powder can be directly reused in the spraying process, reducing raw material loss.

Compared to conventional circular dust removal filter cartridges, the powder spraying room has a stronger compatibility between the industrial flange top square cover dust collector filter element square flange installation structure and the spraying room top square installation plate. A larger effective filtration area can be arranged in the same installation space, and the dust processing capacity per unit time is increased by more than 30%; The polyester coated filter material has excellent powder repellency, and there is almost no dust residue after pulse cleaning. The pressure difference of the filter element is stable during long-term operation, and the energy consumption of the dust removal system fan can be reduced by about 25%; Thickened galvanized support frame has higher compressive strength and will not cause deformation or collapse of the filter body in the face of high dust concentration and large pressure difference conditions. The overall service life is more than twice that of ordinary non coated filter materials; The entire embedded sealing ring does not require additional sealing gaskets, and there are no dust leakage gaps after installation, avoiding the problem of corner powder leakage that is prone to occur when traditional circular filter cartridges are compatible with square mounting plates.

After the filter element runs, the pressure difference rapidly increases. First, check whether the pulse cleaning system's blowing pressure meets the standard. Adjust the blowing pressure to the range of 0.4-0.6MPa and shorten the cleaning cycle to alleviate the problem of rapid powder blockage; After installation, if there is powder leakage at the edge position, check whether the sealing rubber ring of the square flange end cover is padded by debris or the installation screws are unevenly stressed. Clean the installation surface again and tighten the screws diagonally evenly to eliminate the leakage point; After cleaning, a large amount of dust still adheres to the surface of the filter material. Check if a high-pressure water gun or hard brush is used to clean the filter element, and use low-pressure compressed air below 0.3MPa to blow back from the inside of the filter element to avoid damaging the structure of the coating layer; The filter body has local deformation and depression. Check whether the internal support skeleton has detachment or fracture. After stopping the machine and releasing pressure, directly replace the filter element with the corresponding damaged skeleton to prevent dust from penetrating into the clean air side.
