[0036] Example

[0037] like Figures 1-6 As shown, this utility model proposes a quick-locking and replacement device for a dust collector filter cartridge, including a filter cartridge. The filter cartridge includes an annular connecting plate 1 and a rear cover plate 2. Several filter screen mounting plates 5 arranged in a ring are fixedly installed between the annular connecting plate 1 and the rear cover plate 2. The filter screen mounting plates 5 have a double-plate structure. A porous filter screen 6 is passed through several filter screen mounting plates 5, and a pleated filter sleeve 3 is sleeved on several filter screen mounting plates 5. The porous filter screen 6 is installed inside the pleated filter sleeve 3. The annular connecting plate 1 is snapped onto a positioning plate 4, which is fixed to the wall panel of the dust collector. When flue gas enters the filter cartridge from the air inlet 42 provided on the positioning plate 4, the porous filter screen 6 and the pleated filter sleeve 3 can intercept the dust in the flue gas, improving the flue gas purification effect. One of the filter screen mounting plates 5 is threaded with... Several fixing bolts 51 are provided. When the overlapping part of the porous filter screen 6 is inserted into the inner gap of the filter screen mounting plate 5, the end of the fixing bolt 51 is inserted into the mesh hole of the overlapping part of the porous filter screen 6, thereby fixing the annular porous filter screen 6 to the filter screen mounting plate 5. This facilitates the installation and fixing of the porous filter screen 6. The porous filter screen 6 can be replaced by removing the fixing bolts 51, improving the ease of disassembly and assembly. A reinforcing tube 9 is fixedly installed on the rear cover plate 2. A locking screw 7 is movably inserted inside the reinforcing tube 9. The threaded end of the locking screw 7 is threadedly connected to the positioning plate 4, which can firmly install the filter cartridge on the positioning plate 4. This achieves a quick locking and fixing effect on the filter cartridge, improving the firmness of the connection between the filter cartridge and the filter dust collection box. The filter cartridge can be removed from the filter dust collection box by removing the locking screw 7, effectively improving the ease of disassembly and assembly of the filter cartridge.

[0038] Furthermore, several connecting rods 91 are fixedly installed on the outer wall of the reinforcing tube 9. The end of the connecting rod 91 away from the reinforcing tube 9 is fixedly connected to the matching filter screen mounting plate 5. The inner lining support composed of the reinforcing tube 9 and the connecting rods 91 can play a role in reinforcing the filter screen mounting plate 5, thereby improving the overall structural strength of the filter cartridge. A screw positioning seat 41 is fixedly installed on the end of the positioning plate 4 near the reinforcing tube 9. The threaded end of the locking screw 7 passes through the reinforcing tube 9 from the outside of the rear cover plate 2. When the threaded end of the locking screw 7 extends to the outside of the reinforcing tube 9, it is threadedly connected to the screw positioning seat 41, ensuring that the entire filter cartridge can be firmly installed on the positioning plate 4, thereby achieving the purpose of quickly locking and fixing the filter cartridge.

[0039] Secondly, a knob 71 is fixedly installed at the end of the locking screw 7 away from the screw positioning seat 41. Rotating the knob 71 facilitates the rotation of the locking screw 7. An annular sealing ring 72 is movably sleeved on the locking screw 7. When the filter cartridge and the positioning plate 4 are connected as one unit, the annular sealing ring 72 is tightly clamped between the knob 71 and the rear cover plate 2, which can seal the circular opening on the rear cover plate 2 for the locking screw 7 to pass through, preventing flue gas from leaking out from the circular opening. An annular sealing gasket 43 is fixedly installed at one end of the screw positioning seat 41. The end of the reinforcing tube 9 is in close contact with the annular sealing gasket 43, reducing the probability of flue gas entering the interior of the reinforcing tube 9 and improving the sealing performance at the filter cartridge locking structure.

[0040] Furthermore, several positioning rods 101 are fixedly installed on the annular docking plate 1, and several positioning holes 44 are drilled at one end of the positioning plate 4 near the annular docking plate 1. During the filter cartridge installation process, after the filter cartridge is inserted into the dust collector filter box, the positioning rods 101 are inserted into the matching positioning holes 44, which can limit the filter cartridge at one end of the annular docking plate 1. When the locking screw 7 is rotated to lock and fix it in place, the filter cartridge can be prevented from rotating, thus improving its stability during installation.

[0041] Secondly, a first sealing ring 10 is fitted onto the rear cover plate 2. When the filter cartridge is installed on the dust collector filter box, the first sealing ring 10 is tightly clamped between the rear cover plate 2 and the outer wall of the dust collector filter box, which can seal the opening on the dust collector filter box for inserting the filter cartridge. A second sealing ring 11 is engaged and installed on the annular connecting plate 1. When the annular connecting plate 1 and the positioning plate 4 are connected as one unit, the second sealing ring 11 is tightly clamped in the gap between the annular connecting plate 1 and the positioning plate 4, which can seal the gap between the two and effectively improve the sealing performance of the connection between the dust collector filter box and the filter cartridge.

[0042] It is worth noting that filter sleeve positioning rings 8 are fixedly installed on both the annular connecting plate 1 and the rear cover plate 2. When installing the pleated filter sleeve 3, it is first bent into a ring shape, and glue is applied to the part where the ends meet for bonding. Then, the two ends of the annular pleated filter sleeve 3 are respectively inserted into the matching filter sleeve positioning rings 8. At this time, there is a gap between the outer wall of the filter sleeve positioning ring 8 and the inner wall of the filter sleeve positioning ring 8. The rubber ring is pressed into the gap and the end of the pleated filter sleeve 3 is squeezed to ensure that the end of the pleated filter sleeve 3 can be pressed and fixed inside the filter sleeve positioning ring 8. Compared with the traditional binding and fixing method, the firmness of the pleated filter sleeve 3 after installation is improved.

[0043] In this embodiment, during the filter cartridge installation process, the end of the filter cartridge closest to the annular connecting plate 1 is inserted into the dust collector filter box. When the annular connecting plate 1 is aligned with the positioning plate 4 installed on the dust collector filter box, the knob 71 is rotated to drive the locking screw 7 to rotate. When the threaded end of the locking screw 7 is threadedly connected to the screw positioning seat 41, the filter cartridge and the positioning plate 4 are firmly connected as one unit. At this time, the rear cover plate 2 is tightly attached to the outer wall of the dust collector filter box. The rear cover plate 2 can be fixed by a single locking screw 7, which replaces the traditional method of fixing with multiple bolts. This simplifies the operation steps of filter cartridge installation and fixation, and achieves the effect of quick locking and fixing. Removing the locking screw 7 can release the locking and fixing of the rear cover plate 2, making it convenient to remove the filter cartridge from the dust collector filter box, effectively improving the convenience of filter cartridge installation and removal.

[0044] If the porous filter screen 6 is damaged and needs to be replaced after a long period of use, first remove the rubber ring inside the filter sleeve positioning ring 8 to release the clamping fixation on the end of the pleated filter sleeve 3. Then tear the joint between the ends of the pleated filter sleeve 3. Since the joint between the ends of the pleated filter sleeve 3 is glued, it is easy to tear it apart. After tearing it apart, the pleated filter sleeve 3 can be removed from the outside of the filter screen mounting plate 5. After the pleated filter sleeve 3 is removed, remove the fixing bolts 51 used to fix the porous filter screen 6 to release the locking fixation on the overlapping part of the porous filter screen 6. This makes it easy to remove the porous filter screen 6 from the filter screen mounting plate 5 and facilitate the replacement of the porous filter screen 6. In the process of filter cartridge installation and use, the convenient disassembly and assembly of the filter cartridge effectively improves the convenience of dust collector filter cartridge maintenance.

[0045] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
