Description

Technical Field

[0001] This utility model relates to the field of dust collector filter technology, and more specifically, to a dust collector filter cleaning backflushing structure. Background Technology

[0002] When dust removal equipment is working, it needs to draw in external air containing dust and then filter it through the dust removal filter element. This can easily cause dust and debris to adhere to the filter surface of the dust removal filter element, thus causing blockage.

[0003] Currently, commonly used dust collector filter cleaning back-blowing structures suffer from insufficient back-blowing air pressure during use, and the dust and debris cleaned out by back-blowing cannot be directly cleaned and collected. For example, the automatic dust collector filter cleaning back-blowing mechanism disclosed in CN218924161U includes four sets of dust collector filters, a back-blowing air manifold, a pair of back-blowing solenoid valves, and two back-blowing pipes. The four sets of dust collector filters are arranged in a two-by-two configuration. The back-blowing air manifold has an air inlet at the bottom and is connected to an external air source. The pair of back-blowing solenoid valves are respectively located at the top and bottom of the back-blowing air manifold and are both connected to the air passage of the back-blowing air manifold. The two back-blowing pipes are respectively installed on the pair of back-blowing solenoid valves, and several back-blowing air holes are evenly opened on the back-blowing pipes.

[0004] As can be seen from the above-mentioned disclosed scheme, the dust collector filter element cleans its surface by back-blowing through the back-blowing pipe and back-blowing air hole. However, the back-blowing pipe and back-blowing air hole are open-type air blowing, and their air pressure may be insufficient. This will result in the dust and debris deep in the filter hole not being blown out and cleaned, reducing the dust cleaning effect. Moreover, the dust and debris blown out cannot be directly cleaned out, which may cause the dust and debris to directly clog the filter hole again when the dust collector filter element is in normal use. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a dust removal filter element back-blowing structure. This dust removal filter element back-blowing structure, through the filter element shell and the air blowing pipe, allows the blowing force to be continuously pressurized in the air outlet groove, thereby back-blowing the core body and blowing the dust and debris in the filter holes back into the core body, greatly improving the dust removal effect of the dust removal filter element. Furthermore, through the provided guide hood, ash discharge pipe and first solenoid valve, the ash discharge pipe can be opened during the back-blowing of the dust removal filter element, allowing the dust and debris cleaned by the back-blowing of the core body to be directly discharged.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A dust collector filter cartridge backflushing structure includes a dust collector filter cartridge body, which includes a filter cartridge shell. One end of the filter cartridge shell has an air outlet groove. An air outlet pipe and a blowing pipe are fixedly connected to the bottom of the air outlet groove. A one-way valve is fixedly installed on the surface of the blowing pipe. A connecting cap is threaded to one end of the filter cartridge shell. A feed pipe is fixedly connected to the surface of the connecting cap. A second solenoid valve is fixedly installed on the surface of the feed pipe. A core body is threaded to the bottom of the connecting cap. This dust collector filter cartridge backflushing structure, through the filter cartridge shell and the blowing pipe, continuously pressurizes the blowing force within the air outlet groove, thereby backflushing the core body and blowing dust and debris from the filter pores back into the core body, greatly improving the dust collector filter cartridge's cleaning effect. Furthermore, through the provided guide hood, ash discharge pipe, and first solenoid valve, the ash discharge pipe can be opened during backflushing of the dust collector filter cartridge, allowing the dust and debris cleaned by the backflushing core body to be directly discharged.

[0008] Furthermore, the connecting cover is polygonal in shape, and a fixing sleeve is fixedly connected to the bottom of the connecting cover. The fixing sleeve divides the bottom of the connecting cover into a first mounting groove and a second mounting groove. The inner walls of the first mounting groove and the second mounting groove are both provided with internal threads. After the connecting cover is installed with the filter element housing, the core can be directly positioned.

[0009] Furthermore, a connecting ring is fixedly connected to one end of the core, and the outer side of the connecting ring is threadedly connected to the inner wall of the first mounting groove. A flow guide is fixedly connected to the other end of the core, and the outer side of the connecting ring is provided with an external thread, so that one end of the core and the connecting cover can be disassembled and assembled, which facilitates the later replacement of the core.

[0010] Furthermore, one end of the filter element housing is provided with a threaded portion, the surface of which is threadedly connected to the inner wall of the second mounting groove, and a sealing gasket is movably connected to the end face of the threaded portion. The second mounting groove allows the connecting cover and the filter element housing to be disassembled and assembled.

[0011] Furthermore, the bottom of the flow guide is fixedly connected to a ash discharge pipe, and a first solenoid valve is fixedly installed on the surface of the ash discharge pipe. One end of the ash discharge pipe is fixedly connected to a connecting pipe. The first solenoid valve opens when the ash discharge pipe discharges ash, so that the dust and debris filtered by the core can be discharged.

[0012] Furthermore, the bottom of the filter element housing has a central hole, the inner wall of the central hole is movably connected to the surface of the connecting pipe, and the inner wall of the central hole is provided with a sealing sleeve. The inner wall of the sealing sleeve contacts and presses against the surface of the connecting pipe, which facilitates the positioning and sealing of the connecting pipe.

[0013] Furthermore, an intelligent valve is fixedly installed on the surface of the air outlet pipe. The intelligent valve on the air outlet pipe is normally open and closes during backflushing and dust removal to facilitate the sealing of the air outlet groove.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution uses a filter cartridge shell and an air blowing pipe to continuously increase the air pressure in the air outlet groove, thereby back-blowing the core and blowing the dust and debris in the filter holes back into the core, which greatly improves the dust removal effect of the dust filter cartridge.

[0016] (2) This solution uses a flow guide hood, ash discharge pipe and first solenoid valve to open the ash discharge pipe when backflushing the dust filter element, so that the dust and debris cleaned by the backflushing of the element can be discharged directly. Attached Figure Description

[0025] Example 1

[0026] Please see Figures 1-5A dust collector filter element backflushing structure includes a dust collector filter element body 1, which includes a filter element shell 2. The bottom of the filter element shell 2 has a central hole 23. The inner wall of the central hole 23 is movably connected to the surface of a connecting pipe 35. A sealing sleeve is provided on the inner wall of the central hole 23. The inner wall of the sealing sleeve contacts and presses against the surface of the connecting pipe 35, facilitating the positioning and sealing of the connecting pipe 35. One end of the filter element shell 2 has an air outlet groove 21. The bottom of the air outlet groove 21 is fixedly connected to an air outlet pipe 22 and a blowing pipe 25. A smart valve, which is an electromagnetic valve, is fixedly installed on the surface of the air outlet pipe 22. The smart valve on the air outlet pipe 22 is normally open and closes during backflushing to facilitate the sealing of the air outlet groove 21. The surface of the blowing pipe 25... A one-way valve 26 is fixedly installed, which ensures that the air blowing pipe 25 can only blow air into the air outlet groove 21. One end of the air blowing pipe 25 is connected to the air blowing assembly through an air pipe, which facilitates the entry of pressurized gas into the air outlet groove 21 to back-blown and clean the core 3. One end of the filter element shell 2 is threadedly connected to a connecting cover 4. The surface of the connecting cover 4 is fixedly connected to a feed pipe 41. A second solenoid valve 42 is fixedly installed on the surface of the feed pipe 41. The second solenoid valve 42 is normally open and is closed when back-blowing and cleaning the core 3, which increases the sealing effect in the air outlet groove 21 and facilitates the pressurization of the back-blowing gas in the air outlet groove 21. The bottom of the connecting cover 4 is threadedly connected to the core 3. The core 3 is a prior art material with filter holes on its surface and a filter surface inside the core 3.

[0027] The connecting cover 4 is polygonal in shape. A fixing sleeve 43 is fixedly connected to the bottom of the connecting cover 4. The fixing sleeve 43 divides the bottom of the connecting cover 4 into a first mounting groove 44 and a second mounting groove 45. The inner walls of the first mounting groove 44 and the second mounting groove 45 are provided with internal threads. After the connecting cover 4 is installed with the filter element housing 2, the core 3 can be directly positioned. A connecting ring 31 is fixedly connected to one end of the core 3. The outer side of the connecting ring 31 is threaded to the inner wall of the first mounting groove 44. A flow guide shroud 32 is fixedly connected to the other end of the core 3. The outer side of the connecting ring 31 is provided with external threads, so that one end of the core 3 and the connecting cover 4 can be disassembled and assembled, which facilitates the later replacement of the core 3.

[0028] One end of the filter element housing 2 is provided with a threaded part 24. The surface of the threaded part 24 is threadedly connected to the inner wall of the second mounting groove 45. A sealing gasket 46 is movably connected to the end face of the threaded part 24. The second mounting groove 45 allows the connecting cover 4 and the filter element housing 2 to be disassembled and assembled. The bottom of the flow guide shroud 32 is fixedly connected to a ash discharge pipe 33. A first solenoid valve 34 is fixedly installed on the surface of the ash discharge pipe 33. One end of the ash discharge pipe 33 is fixedly connected to a connecting pipe 35. The first solenoid valve 34 is opened when the ash discharge pipe 33 discharges ash, so that the dust and debris filtered by the core 3 can be discharged.

[0029] When the dust collector filter element body 1 needs to be cleaned and backflushed, the dust collector filter element body 1 is cleaned and backflushed. First, the first solenoid valve 34 is opened, and the second solenoid valve 42 and the smart valve are closed, so that the ash discharge pipe 33 can be opened to discharge ash downwards. At the same time, the feed pipe 41 and the air outlet pipe 22 are closed, so that the air outlet groove 21 is in a sealed state. Then, the air blowing assembly blows pressurized air into the air outlet groove 21 through the air pipe and the air blowing pipe 25. Since the feed pipe 41 and the air outlet pipe 22, which are connected to the outside, are in a closed state, the air can only be blown on the surface of the core body 3 and backflushed into the core body 3 through the filter holes. Since the filter holes are blocked by dust and debris, the backflushing gas is pressurized in the air outlet groove 21. After the air pressure increases, all the dust and impurities in the filter holes are backflushed into the core body 3. At the same time, the dust and impurities blown out from the core body 3 are discharged from the dust collector filter element body 1 through the ash discharge pipe 33.

[0030] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
