Description

Technical Field

[0001] This utility model relates to the field of dust collector filter cartridge technology, and more specifically, it relates to a dust collector filter cartridge with good wear resistance. Background Technology

[0002] Currently, the processing of parts generates a large amount of exhaust gas, which easily contains fine debris and dust. Direct discharge of this debris and dust can affect the health of surrounding operators, and long-term inhalation can easily lead to respiratory diseases. Therefore, dust removal equipment is usually used to treat this debris and dust. The main filtering component in dust removal equipment is the dust collector cartridge. However, there are many specifications and styles of dust collector cartridges available now. Various filtration precision dust collector cartridges must be customized according to the needs, which is time-consuming, labor-intensive, and costly. Furthermore, traditional dust collector cartridges have poor wear resistance and are easily worn by impacts from dust and debris, which will affect the dust removal effect of the dust collector cartridges after long-term use. Moreover, most of them are fixed by bolts, which means that tools are needed for disassembly later, making it difficult to clean the dust on the surface. Utility Model Content

[0029] In this embodiment, a heat-absorbing layer 10 is provided on the outer wall of the heat insulation layer 9, and a wear-resistant layer 11 is provided on the outer wall of the heat-absorbing layer 10. The heat insulation layer 9 is made of glass fiber plate, the heat-absorbing layer 10 is made of aluminum alloy plate, and the wear-resistant layer 11 is made of polyamide fiber.

[0030] More specifically, by incorporating a fine filter cartridge 3 inside the coarse filter cartridge 1, the coarse filter cartridge 1 can be used directly when the filtration accuracy requirement is low, while the coarse filter cartridge 1 and the fine filter cartridge 3 can be connected together when the filtration accuracy requirement is high. Therefore, it is not necessary to customize dust collector filter cartridges according to filtration needs, which reduces costs and improves engineering efficiency. Furthermore, by setting a wear-resistant layer 11, the wear resistance of the coarse filter cartridge 1 and the fine filter cartridge 3 can be increased, thereby increasing their service life. By setting a heat-absorbing layer 10 and a heat-insulating layer 9, the temperature on the wear-resistant layer 11 can be absorbed, preventing long-term high temperature from damaging the wear-resistant layer 11 and facilitating its use.

[0031] Please see Figure 1 , Figure 2 and Figure 4As an embodiment for disassembling and fixing the coarse filter cartridge 1: A mounting ring 12 is fixedly provided on the upper part of the outer wall of the coarse filter cartridge 1.

The diameter of the snap-fit ​​hole 17 is equal to that of the snap-fit ​​block 15. A pin 18 is slidably provided on one side of the upper end face of the snap-fit ​​block 15. A slot 19 is correspondingly opened on the upper end face of the outer connecting ring 13. The lower end of the pin 18 is located inside the slot 19. A pull block 20 is provided on the upper end of the pin 18. A spring 21 is fixed between the pull block 20 and the snap-fit ​​block 15. The lower end of the pin 18 is inclined.

[0032] Specifically, when the user needs to disassemble the coarse filter cartridge 1, the lower end of the pin 18 can be disengaged from the slot 19 by pulling the pull block 20. Then, the coarse filter cartridge 1 can be rotated so that the snap-fit ​​block 15 can enter the snap-fit ​​hole 17. At this time, the coarse filter cartridge 1 and the outer ring 13 can be separated. Then, the coarse filter cartridge 1 and the fine filter cartridge 3 can be separated by rotating the screw block 7, which makes it convenient to clean the dust on the upper part.

Therefore, it is not necessary to customize dust collector filter cartridges according to filtration needs, which reduces costs and improves engineering efficiency. Furthermore, by setting the wear-resistant layer 11, the wear resistance of the coarse filter cartridge 1 and the fine filter cartridge 3 can be increased, thereby increasing their service life. By setting the heat-absorbing layer 10 and the heat-insulating layer 9, the temperature on the wear-resistant layer 11 can be absorbed, preventing long-term high temperature from damaging the wear-resistant layer 11, which is convenient to use. When the user needs to disassemble the coarse filter cartridge 1, the lower end of the pin 18 can be disengaged from the slot 19 by pulling the pull block 20. Then, the coarse filter cartridge 1 can be rotated so that the snap-fit ​​block 15 can enter the snap-fit ​​hole 17. At this time, the coarse filter cartridge 1 and the outer connecting ring 13 can be separated. Then, the coarse filter cartridge 1 and the fine filter cartridge 3 can be separated by rotating the screw block 7, which facilitates the cleaning of the dust on the upper part.
