Therefore, they cannot be understood as limitations on the present invention.

[0024] Please refer to Figure 1 , Figure 2 A high-sealing filter chamber for a filter cartridge dust collector comprises a mounting wall plate 1, a front wall plate 2 and a side wall plate 3. The mounting wall plate 1 and the front wall plate 2 are arranged relatively parallel to each other. The side wall plate 3 connects the circumferential edges of the mounting wall plate 1 and the front wall plate 2 and is assembled together to form a hollow filter chamber. The mounting wall plate 1 is provided with a mounting hole 4. The filter cartridge is located inside the filter chamber and one end of the filter cartridge is sealed and fixed on the mounting hole 4.

[0025] A concentric flange gasket 5 is installed on the outside of the mounting wall panel 1 at the position corresponding to the mounting hole 4. The inner diameter of the flange gasket 5 is the same as the hole diameter of the mounting hole 4. A reinforcing rib 6 is also provided on the outside of the mounting wall panel 1, and the reinforcing rib 6 covers the edge of the flange gasket 5.

[0026] The filter cartridge dust collector protected by the utility model has a high-sealing filter chamber, the filter cartridge is fixed on the mounting hole 4 of the mounting wall plate 1, and the flange pad 5 is fixed outside the mounting hole 4, which plays a role in improving the strength of the plate around the mounting hole 4, thereby improving the flatness of the mounting wall plate 1, and a reinforcing rib 6 is fixed above the flange pad 5 to further strengthen the fastening. When the filter cartridge is installed, even if a pulling force is generated on the mounting wall plate 1 under the action of the filter cartridge's own weight and other forces, the mounting wall plate 1 will not be deformed, which can effectively ensure the airtightness of the cavity, prevent the filter cartridge from being skewed and loose, improve the filtering effect, and improve the safety of the equipment.

[0027] In one embodiment, the number of mounting holes 4 is m*n, where m is the number of rows and m≥1, n is the number of columns and n≥1, and the position of each mounting hole 4 outside the filter chamber corresponds to the mounting flange pad 5. The flange pad 5, the mounting hole 4 and the filter cartridge are in a one-to-one correspondence. Each filter cartridge is fixed on the mounting wall plate 1, and the flange pad 5 is provided on the outside of the mounting hole 4 to enhance the thickness and strength of the area, avoid deformation, improve the flatness of the mounting wall plate 1, and ensure the airtightness of the filter cartridge after installation.

[0028] Furthermore, the inner circle contour of the flange gasket 5 completely coincides with the contour of the mounting hole 4, the outer diameter of the flange gasket 5 is larger than the outer diameter of the filter cartridge, and the end of the filter cartridge completely falls into the area of ​​the flange gasket 5 corresponding to it; the above structure neither affects the installation of the filter cartridge nor improves the contact surface strength between the filter cartridge and the flower plate, thereby ensuring the flatness of the filter cartridge installation surface.

[0029] Furthermore, the flange gasket 5 is in a circular ring shape, with an outer diameter of 150-500 mm, an inner diameter equal to the diameter of the mounting hole 4, and a thickness of 5-8 mm, which can achieve a better effect of improving strength.

The edges of the m flange gaskets 5 in the same column are all covered under the same reinforcing rib 6. The reinforcing rib 6 can not only further reinforce the flange gaskets 5, but also connect the flange gaskets 5 in the same column, thereby improving the overall flatness of the installed wall panel 1.

[0031] In a more preferred embodiment, the number of reinforcing ribs 6 is 2n, and each column of flange gaskets 5 is respectively covered and fixed with a reinforcing rib 6 on both sides in the vertical direction, thereby achieving the effect of evenly fixing the two sides, preventing the flange gaskets 5 from being subjected to uneven force and causing one side to warp or loosen, thereby affecting the flatness of the installed wall panel 1, and effectively improving the connection and reinforcement effect of the reinforcing ribs 6.

[0032] More preferably, the overall length of the reinforcement rib 6 is L, and the overall thickness range of the reinforcement rib 6 is L / 400-L / 100, which can effectively improve the tensile strength of the installed wall panel 1; the reinforcement rib 6 can adopt profile structures such as flat steel, angle steel, rectangular tube, H-shaped steel, channel steel, etc.

[0033] More preferably, the thickness of the mounting wall panel 1 is 2-4 mm; the mounting wall panel 1 has an overall symmetrical structure, and the aspect ratio of the mounting wall panel 1 is 1.3-2, which can achieve good strength support effect and flatness requirements.
