[0002] A cartridge dust collector is a device that filters dust from the air. One of the core components of a dust collector is the cartridge. The existing cartridge installation structure is to install three frames on one side of the dust collector body as cartridge support components, and to converge the three frames into one at the other end. A thread is provided at the end for connecting seals and end covers. Installation and disassembly are achieved by tightening and loosening nuts, a process that is rather cumbersome. Furthermore, since the bracket is only fixed to the wall panel on one side of the dust collector, the bracket is subjected to uneven force, which can easily cause deformation of the wall panel and affect the life of the equipment.

[0003] In the existing technology, the installation steps of the filter cartridge in the filter cartridge dust collector are cumbersome, which makes it inconvenient to quickly install and remove the filter cartridge. In addition, the root of the filter cartridge bracket is unevenly stressed, which can easily cause the wall panel to deform, affecting the service life and effect of the filter cartridge dust collector and making it inconvenient for daily operation and maintenance.

[0017] Optionally, a filter cartridge bracket is provided between the first filter cartridge retaining ring and the second filter cartridge retaining ring.

[0018] The above technical solution guides the filter cartridge through the filter cartridge bracket, and at the same time, the filter cartridge bracket can support the box body and the partition, thereby ensuring the stability of the box body structure.

[0019] Optionally, the end cover is rotatably connected to the outer wall of the box body, the end cover is used to seal the first filter cartridge retaining ring, and the outer wall of the box body is rotatably connected to a handle on one side of the end cover.

[0020] The above technical solution seals the first filter cartridge retaining ring through the end cover and limits the end cover through the handle, which simplifies the disassembly and assembly of the end cover, thereby further simplifying the disassembly and assembly of the filter cartridge.

[0021] Optionally, both ends of the filter cartridge are matched with sealing gaskets.

[0022] The above technical solution further ensures the sealing performance of the filter cartridge by sealing the two ends of the filter cartridge with a sealing gasket.

[0023] Optionally, an air inlet valve and an exhaust valve are provided on the outer wall of the connecting pipe outside the end cover.

[0024] The above technical solution inflates the airbag through the air inlet valve and deflates the airbag through the exhaust valve, which speeds up the working efficiency of inflation and deflation, thereby further ensuring the efficiency of disassembly and assembly of the filter cartridge.

[0025] Optionally, the outer wall of the airbag is provided with raised patterns, and a sealing plate is installed between the airbag and the filter cartridge.

[0026] In the above technical solution, after the airbag is inflated, the raised patterns closely fit the wall surfaces of the sealing plate and the end cover, dividing the contact surfaces to form multiple sealing strips, which has a better sealing effect than an airbag without raised patterns.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The filter cartridge dust collector of the novel filter cartridge installation structure cooperates with the end cover, the air bag and the first through hole. When the filter cartridge needs to be installed and removed, it is only necessary to remove the end cover to put the filter cartridge in or take it out of the box body, which simplifies the installation and removal steps of the filter cartridge and facilitates the rapid installation and removal of the filter cartridge, ensuring the convenience of the device. At the same time, the air bag is used to squeeze and position the filter cartridge to ensure the sealing of the filter cartridge, thereby ensuring the filtering effect of the filter cartridge; further, after the filter cartridge of the present application is installed, the box body clamps and fixes the filter cartridge through the inner wall and the end cover installed on the outer wall, so that the force on the filter cartridge is uniform, avoiding deformation of the wall panel of the box body, ensuring the service life and effect of the filter cartridge dust collector, and facilitating daily operation and maintenance;

[0029] 2. After the airbag of the present application is inflated, its force causes the sealing plate and the filter cartridge and the sealing gaskets at both ends to be pressed against each other, so that the airbag is pressed against the inner wall of the first filter cartridge retaining ring, thereby achieving sealing. Compared with the traditional threaded compression seal, it is faster and more convenient, and the installation and removal of the filter cartridge are simpler and more convenient, saving time and effort. The high-pressure gas required for the airbag is generally available in industrial plants, and there are no high requirements for the type and purity of the high-pressure gas. It only needs to be non-toxic and non-corrosive, easy to obtain, and has good universality.

[0030] 3. The filter cartridge bracket of the present application serves as a guide rail to quickly slide the filter cartridge into the second filter cartridge retaining ring when installing the filter cartridge. It is also the internal support structure of the box body, which facilitates the installation of the filter cartridge while strengthening the rigidity of the box body. Compared with the ordinary filter cartridge bracket, it reduces the clean air flow resistance inside the filter cartridge. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Specifically, when working, when installing the filter cartridge 5, first remove the end cover 7 from the box body 1, and then pass the filter cartridge 5 through the end cover 7 so that one end of the filter cartridge 5 contacts the inner wall of the box body 1. After the filter cartridge 5 is placed inside the box body 1, the end cover 7 is installed on the box body 1. At this time, the airbag 11 is located between the end cover 7 and the filter cartridge 5. The airbag 11 is inflated through the connecting pipe 19. After the airbag 11 is inflated, it pushes the filter cartridge 5 to make close contact with the inner wall of the box body 1, thereby completing the During the installation of the filter cartridge 5, the inner wall of the housing 1 seals one side of the filter cartridge 5, and the inflated airbag 11 seals the other side of the filter cartridge 5, ensuring the sealing of the filter cartridge 5. At this time, after the outside air enters the housing 1 through the air inlet 13, it can be filtered through the filter cartridge 5 and then discharged through the air outlet 14 to complete the dust removal work. When it is necessary to disassemble and replace the filter cartridge 5, the airbag 11 can be deflated through the connecting pipe 19, and then the end cover 7 can be installed. By removing it from the outer wall of the box body 1, the filter cartridge 5 can be pulled out from the first through hole 18, so that the filter cartridge 5 can be replaced. Optionally, when the filter cartridge 5 is installed inside the box body 1, the filter cartridge 5 is located outside the air outlet 14. The utility model cooperates with the end cover 7, the air bag 11 and the first through hole 18. When the filter cartridge 5 needs to be installed and removed, only the end cover 7 needs to be removed to put the filter cartridge 5 into or take it out of the box body 1, which simplifies the installation and removal steps of the filter cartridge 5 and facilitates quick installation and removal. Removing the filter cartridge 5 ensures the convenience of the device. At the same time, the present application uses the airbag 11 to extrude and position the filter cartridge 5, ensuring the sealing of the filter cartridge 5, thereby ensuring the filtering effect of the filter cartridge 5; further, after the installation of the filter cartridge 5 of the present application is completed, the box body 1 clamps and fixes the filter cartridge 5 through the inner wall and the end cover 7 installed on the outer wall, so that the force on the filter cartridge 5 is uniform, avoiding deformation of the wall panel of the box body 1, ensuring the service life and effect of the filter cartridge dust collector, and facilitating daily operation and maintenance.

[0042] like Figure 2As shown, an embodiment is shown, the inner wall of the box body 1 is matched with a partition 20, and the partition 20 is used to separate the box body 1 into a cavity 22 and a clean air cavity 4, the air outlet 14 is opened on the side wall of the clean air cavity 4, the air inlet 13 and the first through hole 18 are both opened on the side wall of the cavity 22, and the outer wall of the partition 20 is coaxially opened with a second through hole 21 on one side of the first through hole 18, the filter cartridge 5 is located inside the cavity 22 and is detachably connected to the partition 20, and the air inlet 13 is connected to the air outlet 14 through the filter cartridge 5 and the second through hole 21 in turn.

[0043] Specifically, the present application divides the box body 1 into a cavity 22 and a clean air cavity 4 by a partition 20, and sets the air outlet 14 on the side wall of the clean air cavity 4, so that it is easy to change the air outlet direction of the air outlet 14 to adapt to specific work needs; when the present application installs the filter cartridge 5, after the filter cartridge 5 is inserted into the inner wall of the cavity 22 through the first through hole 18, one end of the filter cartridge 5 is brought into contact with the partition 20, and then the end cover 7 and the air bag 11 are cooperated so that the air bag 11 pushes one end of the filter cartridge 5 to fit with the partition 20, completing The filter cartridge 5 is fixed, and at this time, the outside air enters the cavity 22, passes through the filter cartridge 5 and the second through hole 21, enters the clean air cavity 4, and is finally discharged from the air outlet 14 to complete the dust removal work, thereby separating the unfiltered and filtered air through the partition 20. The filter cartridge 5 located inside the cavity 22 can cooperate with the ash hopper 2 for simple cleaning work; and the two ends of the filter cartridge 5, one end contacts the partition 20, and the other end contacts the box body 1, so that the force on the filter cartridge 5 is uniform, while avoiding deformation of the wall panel of the box body 1.

[0044] In one embodiment, the number of the first through hole 18, the second through hole 21 and the filter cartridge 5 are all multiple, and the number of the first through hole 18, the second through hole 21 and the filter cartridge 5 are equal; so that multiple filter cartridges 5 can be installed inside the cavity 22, and the working efficiency of the device is ensured by filtering the air through the filter cartridge 5.

[0045] In one embodiment, a first filter cartridge retaining ring 6 is provided on the outer wall of the box body 1 outside the first through hole 18, and a second filter cartridge retaining ring 17 is provided on the outer wall of the partition 20 outside the second through hole 21. The first filter cartridge retaining ring 6 and the second filter cartridge retaining ring 17 are both detachably connected to the filter cartridge 5.

[0046] Specifically, when the filter cartridge 5 needs to be installed on one side of the partition 20, when the filter cartridge 5 passes through the first through hole 18, the first filter cartridge retaining ring 6 guides the filter cartridge 5 until one end of the filter cartridge 5 contacts the second filter cartridge retaining ring 17. The second filter cartridge retaining ring 17 supports and positions the filter cartridge 5, ensuring the stability of the filter cartridge 5 during installation; when the filter cartridge 5 is installed, the first filter cartridge retaining ring 6 limits the inflated airbag 11, ensuring that the airbag 11 can push the filter cartridge 5 to make close contact with the second filter cartridge retaining ring 17, further ensuring the sealing effect of the filter cartridge 5.

[0047] like Figure 1-Figure 2 As shown, in one embodiment, an ash hopper 2 is provided at the bottom of the box body 1, the ash hopper 2 is communicated with the cavity 22, a valve is detachably connected to the bottom of the ash hopper 2, and a plurality of legs 3 are provided at the bottom of the box body 1.

[0048] During use, when the box body 1 is performing normal filtering work, the valve (not shown in the figure) can be installed at the bottom of the ash hopper 2 to avoid affecting the filtering work of the filter cartridge 5. When it is necessary to clean the dust on the surface of the filter cartridge 5, the box body 1 can be knocked to drive the filter cartridge 5 to vibrate, and the valve can be removed so that the dust falling on the surface of the filter cartridge 5 can fall through the bottom of the ash hopper 2, thereby performing the recommended cleaning work on the filter cartridge 5 and ensuring the working effect of the device; optionally, the support legs 3 play a supporting role for the box body 1 and leave space for installing the ash hopper 2.

[0049] In one embodiment, a filter cartridge holder 16 is provided between the first filter cartridge retaining ring 6 and the second filter cartridge retaining ring 17. When the filter cartridge 5 enters the interior of the cavity 22 through the first through hole 18, the filter cartridge holder 16 guides the filter cartridge 5. At the same time, the filter cartridge holder 16 connects the partition 20 and the wall panel of the box body 1, ensuring the stability of the structure of the box body 1. The filter cartridge holder 16 of the present application serves as a guide rail to quickly slide the filter cartridge 5 into the second filter cartridge retaining ring 17 when installing the filter cartridge 5. It is also an internal support structure of the box body 1, which facilitates the installation of the filter cartridge 5 while strengthening the rigidity of the box body 1, and reduces the clean air flow resistance inside the filter cartridge 5 compared with the ordinary filter cartridge holder 16. Optionally, there are two filter cartridge holders 16 and they are located on both sides below the filter cartridge 5.

[0050] like Figure 5 As shown, in one embodiment, the end cover 7 is rotatably connected to the outer wall of the box body 1 , the end cover 7 is used to seal the first filter cartridge retaining ring 6 , and the outer wall of the box body 1 is rotatably connected to a handle 15 on one side of the end cover 7 .

[0051] When in use, the present application cooperates with the end cover 7 and the handle 15. When the filter cartridge 5 needs to be taken out from the first through hole 18, it is only necessary to rotate the handle 15 to move it away from one side of the end cover 7 and rotate the end cover 7 so that the end cover 7 no longer blocks the first through hole 18, thereby taking out the filter cartridge 5; when the filter cartridge 5 needs to be installed, the end cover 7 can be rotated to one side of the first filter cartridge retaining ring 6 and the handle 15 can be rotated to limit the end cover 7, so that the installation of the end cover 7 and the filter cartridge 5 can be completed, which simplifies the disassembly and assembly of the end cover 7, thereby simplifying the disassembly and assembly of the filter cartridge 5 and ensuring the convenience of the device; at the same time, when the high-pressure gas enters the airbag 11 to expand it, the airbag 11 expands and forces the filter cartridge 5 to contact the second filter cartridge retaining ring 17, while forcing the airbag 11 to cling to the first filter cartridge retaining ring 6 and press the end cover 7, and the end cover 7 is buckled by the handle 15 to limit displacement, thereby achieving sealing, ensuring the fixing effect of the handle 15 on the end cover 7, thereby ensuring the stability of the device during operation.

[0052] like Figure 2-Figure 5 As shown, in one embodiment, both ends of the filter cartridge 5 are matched with sealing gaskets 8, the outer wall of the connecting pipe 19 is provided with an air intake valve 9 and an exhaust valve 10 on the outside of the end cover 7, the outer wall of the air bag 11 is provided with raised patterns, and a sealing plate 12 is installed between the air bag 11 and the filter cartridge 5.

[0053] When in use, an air inlet valve 9 and an exhaust valve 10 are installed on the outside of the connecting pipe 19. The air inlet valve 9 and the exhaust valve 10 are communicated with the airbag 11. The air inlet valve 9 is connected to the high-pressure gas in the factory area. The air inlet valve 9 is opened, and the high-pressure gas enters the airbag 11 to expand it. After the airbag 11 expands, it forces the sealing plate 12 to press the sealing gaskets 8 at both ends of the filter cartridge 5, and forces the airbag 11 to cling to the first filter cartridge retaining ring 6 and press the end cover 7. The end cover 7 is buckled by the handle 15 to limit the displacement, thereby achieving sealing; the exhaust valve 10 is connected to the atmosphere, the air inlet valve 9 is closed, the exhaust valve 10 is opened, the high-pressure gas is discharged into the atmosphere, the airbag 11 retracts, and after turning the handle 15, the end cover 7 can be opened to install or replace the filter cartridge 5. There are raised lines on the surface of the airbag 11. After 11 is inflated, the raised patterns fit tightly against the wall of the sealing plate 12 and the end cover 7, dividing the contact surface to form multiple sealing belts, which has a better sealing effect than the airbag 11 without raised patterns; the airbag 11 of the present application expands after being inflated, and its force causes the sealing plate 12 and the filter cartridge 5 and the sealing gaskets 8 at both ends to be pressed against each other, so that the airbag 11 is pressed against the inner wall of the first filter cartridge retaining ring 6, thereby achieving sealing. Compared with the traditional threaded compression seal, it is faster and more convenient, and the installation and removal of the filter cartridge 5 is simpler and more convenient, saving time and effort. The high-pressure gas required for the airbag 11 is generally available in industrial plants, and there are no high requirements for the type and purity of the high-pressure gas. It only needs to be non-toxic and non-corrosive, easy to obtain, and has good universality.

[0054] To sum up, during the specific use of this application, the air inlet valve 9 is closed, the exhaust valve 10 is opened, the gas in the airbag 11 is discharged, the handle 15 is opened, the end cover 7 is opened, the filter cartridge 5 is pushed into the second filter cartridge retaining ring 17 along the filter cartridge bracket 16, and the sealing plate 12 is installed. Then the end cover 7 is closed, the handle 15 is closed, the exhaust valve 10 is closed, and the air inlet valve 9 is opened. High-pressure gas enters the airbag 11, causing the airbag 11 to expand. After the airbag 11 expands, it forces the sealing plate 12 to press the sealing gaskets 8 at both ends of the filter cartridge 5, forcing the airbag 11 to be close to the first filter cartridge retaining ring 6, thereby achieving sealing; the entire installation process is simple, easy for workers to operate, convenient for inspection and maintenance, and low in operation and maintenance costs.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
