Description

Technical Field

[0001] This application relates to the technical field of filter element cleaning, and in particular to a dust collection box for low-power filter element cleaning. Background Technology

[0002] In factories, many machines generate a lot of dust during production. This dust is released into the air with the airflow, polluting the environment and posing health hazards to operators. Therefore, dust collectors are needed to filter and separate the dust in the air. A dust collector is a device used to remove dust, particulate matter and other pollutants from the air. A fan draws dusty air into the dust collector, where the dust is trapped on the surface of the filter element, and clean air passes through the filter element.

[0003] The filter element has a lot of powder and dust adhering to it. When there is too much powder and dust on the filter element, it is easy to clog the filter element and affect the filtration efficiency of the dust collector. Utility Model Content

[0004] To facilitate the cleaning of the filter cartridges inside the dust collection box, this application provides a dust collection box with low power consumption for filter cartridge cleaning.

[0005] This application provides a low-power filter cleaning dust collection box, which adopts the following technical solution:

[0006] A low-power filter cleaning dust collector includes a dust collector body, an inlet pipe and an outlet pipe communicating with the dust collector body, a support plate inside the dust collector body dividing the dust collector body into a lower inlet chamber and an upper outlet chamber, the outlet pipe communicating with the outlet chamber, the end of the inlet pipe being located at the bottom of the inlet chamber and communicating with the inlet chamber, a plurality of filter elements located in the inlet chamber being arranged below the support plate, a plurality of air passage holes communicating with the filter elements being opened on the support plate, and a plurality of cleaning components corresponding one-to-one with the air passage holes being installed in the outlet chamber. The assembly includes a connecting pipe, a sheath, a connecting sleeve, and a cover plate. One end of the connecting pipe extends from the top of the dust collector housing. The connecting sleeve is located inside the sheath and is slidably connected to the sheath. The end of the connecting sleeve is fixedly connected to the cover plate. A rotating blade is provided inside the filter element. The rotating blade includes a main shaft, a connecting plate, and a side shaft. The main shaft is connected to the connecting pipe. Both ends of the connecting plate are connected to the main shaft and the side shaft. A connecting air passage is provided inside the main shaft, the connecting plate, and the side shaft. An eccentric row of air holes is provided on the side shaft. A first air pipe is connected to the sheath. The first air pipe is connected to the sheath above the connecting sleeve.

[0007] By adopting the above technical solution, gas is transported into the dust collector through the air inlet pipe. The gas passes through the filter element and enters the air outlet chamber, and is then sent out through the air outlet pipe. When the filter element needs to be cleaned, air is blown into the first air pipe, which moves the connecting sleeve and the cover plate downward to block the air passage. Air is then blown into the connecting pipe, and the gas enters the main shaft, connecting plate, and side shaft. The gas is blown out through the air outlet on the side shaft, blowing off the dust adhering to the filter element. At the same time, because the air outlet on the side shaft is eccentrically opened, the thrust generated during the air outlet process drives the rotating blade to rotate, thereby improving the cleaning efficiency of the filter element.

[0008] Optionally, an elastic spring is provided between the cover plate and the filter element.

[0009] By adopting the above technical solution, when air is blown into the first air pipe and the cover moves downward, the elastic spring is compressed. After the air is stopped blowing into the first air pipe, the compressed elastic spring releases its elastic force, pushing the cover to move upward, and the filter element performs the filtration work.

[0010] Optionally, an air storage tank is installed on the dust removal box, and a main air inlet pipe is connected to the air storage tank. The main air inlet pipe is connected to all the first air pipes through a two-way valve group.

[0011] By adopting the above technical solution, gas is supplied to the main air inlet pipe through the gas storage tank, and the connection between all the first air pipes and the main air inlet pipe is controlled by the two-way valve group.

[0012] Optionally, a support pipe is provided at the bottom of the dust collection box, a rotating pipe is rotatably connected inside the support pipe, an air blowing pipe is connected to the rotating pipe, and a row of air blowing holes is eccentrically opened on the air blowing pipe.

[0013] By adopting the above technical solution, air is blown into the rotating tube through the air blowing holes on the air blowing tube. At the same time, because the air blowing holes on the air blowing tube are eccentrically opened, the rotating tube and the air blowing tube rotate during the air blowing process, which facilitates the cleaning of dust adhering to the inner wall of the bottom of the dust collection box.

[0014] Optionally, the support pipe is provided with two bearings, the rotating pipe is fixedly connected to the inner rings of the two bearings, and the rotating pipe is provided with several air inlets.

[0015] By adopting the above technical solution, air is blown into the support pipe, air is blown into the rotating pipe through the air inlet, and the rotating pipe can rotate easily within the support pipe through the bearing.

[0016] Optionally, the gas storage tank is connected to a second gas pipe, which is connected to the cavity between two bearings in the support pipe.

[0017] By adopting the above technical solution, air is blown into the second air pipe through the air storage tank, and air is blown into the support pipe through the second air pipe.

[0018] Optionally, the dust collection box is equipped with an observation mirror corresponding to the air inlet chamber.

[0019] By adopting the above technical solution, the filter element inside the dust collector can be easily observed through the observation mirror.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] Gas is delivered to the dust collector through the inlet pipe, passes through the filter element into the outlet chamber, and is then sent out through the outlet pipe. When the filter element needs to be cleaned, air is blown into the first air pipe, which moves the connecting sleeve and the cover plate downward to block the air passage. Air is then blown into the connecting pipe, and the gas enters the main shaft, connecting plate, and side shaft. The gas is then blown out through the outlet hole on the side shaft to blow off the dust adhering to the filter element.

[0022] Because the air outlet on the side shaft is eccentrically located, the air outlet on the side shaft generates thrust during the air discharge process, which drives the rotating blade to rotate, thereby improving the cleaning efficiency of the filter element.

[0023] By blowing air into the rotating tube, air is blown through the air holes on the air tube. At the same time, because the air holes on the air tube are eccentrically opened, the rotating tube and the air tube rotate during the air blowing process, which facilitates the cleaning of dust adhering to the inner wall of the bottom of the dust collector.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a dust collection box for cleaning low-power filter cartridges.

[0033] Reference Figures 1-6 A dust collector for cleaning low-power filter cartridges 14 includes a dust collector body 1, an air inlet pipe 11 and an air outlet pipe 12 connected to the dust collector body 1, a support plate 13 inside the dust collector body 1, the support plate 13 dividing the dust collector body 1 into an air inlet chamber located below and an air outlet chamber located above, the air outlet pipe 12 being connected to the air outlet chamber, the end of the air inlet pipe 11 being located at the bottom of the air inlet chamber and being connected to the air inlet chamber, a plurality of filter cartridges 14 located in the air inlet chamber being arranged below the support plate 13, a plurality of air passage holes 131 connected to the filter cartridges 14 being opened on the support plate 13, a fan being connected to the air outlet pipe 12, gas being transported to the dust collector through the air inlet pipe 11, the gas passing through the filter cartridges 14 into the air outlet chamber, and being discharged through the air outlet pipe 12.

[0034] The exhaust chamber is equipped with several cleaning components 2 that correspond one-to-one with the air passage 131. The cleaning components 2 include a connecting pipe 21, a protective sleeve 22, a connecting sleeve 23, and a cover plate 24. One end of the connecting pipe 21 extends from the top of the dust collector 1. The connecting sleeve 23 is located inside the protective sleeve 22 and is slidably connected to the protective sleeve 22. The end of the connecting sleeve 23 is fixedly connected to the cover plate 24. A rotating blade 3 is provided inside the filter element 14. The rotating blade 3 includes a main shaft 31, a connecting plate 32, and a side shaft 33. The main shaft 31 is connected to the connecting pipe 21. Both ends of the connecting plate 32 are connected to the main shaft 31 and the side shaft 33. The main shaft 31, the connecting plate 32, and the side shaft 33 are all provided with a connected air passage. A row of air passages 331 is eccentrically provided on the side shaft 33. A first air pipe 26 is connected to the protective sleeve 22. The first air pipe 26 is connected to the protective sleeve 22 above the connecting sleeve 23. Air is blown into the first air pipe 26, causing the connecting sleeve 23 to move the cover plate 24 downwards, blocking the air passage 131. All connecting pipes 21 are connected to fans, and air is blown into the connecting pipes 21 by the fans. The air enters the main shaft 31, connecting plate 32 and side shaft 33, and is blown outwards through the air outlet 331 on the side shaft 33, blowing off the dust adhering to the filter element 14. At the same time, because the air outlet 331 on the side shaft 33 is eccentrically opened, during the air outlet 331 on the side shaft 33, the thrust during the air outlet process drives the rotating blade 3 to rotate, thereby improving the cleaning efficiency of the filter element 14.

[0035] An elastic spring 25 is provided between the cover plate 24 and the filter element 14. When air is blown into the first air pipe 26 and the cover plate 24 moves downward, the elastic spring 25 is compressed. After the air is stopped blowing into the first air pipe 26, the compressed elastic spring 25 releases its elastic force, pushing the cover plate 24 to move upward, and the filter element 14 performs the filtration work.

[0036] An air storage tank 4 is installed on the dust collector housing 1. A main air inlet pipe 41 is connected to the air storage tank 4. The main air inlet pipe 41 is connected to all the first air pipes 26 through a two-way valve group 42. Air is supplied to the main air inlet pipe 41 through the air storage tank 4, and the connection between all the first air pipes 26 and the main air inlet pipe 41 is controlled through the two-way valve group 42.

[0037] A support pipe 5 is provided at the bottom of the dust collector 1. A rotating pipe 51 is rotatably connected inside the support pipe 5. An air blowing pipe 52 is connected to the rotating pipe 51. A row of air blowing holes 521 is eccentrically opened on the air blowing pipe 52. By blowing air into the rotating pipe 51, air is blown through the air blowing holes 521 on the air blowing pipe 52. At the same time, due to the eccentric opening of the air blowing holes 521 on the air blowing pipe 52, the rotating pipe 51 and the air blowing pipe 52 rotate during the air blowing process, which facilitates the cleaning of dust adhering to the inner wall of the bottom of the dust collector 1.

[0038] Two bearings 53 are installed inside the support pipe 5. The rotating pipe 51 is fixedly connected to the inner ring of the two bearings 53. The bearings 53 facilitate the rotation of the rotating pipe 51 inside the support pipe 5. The air tank 4 is connected to a second air pipe 43. The second air pipe 43 is connected to the cavity between the two bearings 53 inside the support pipe 5. Several air inlets 511 are opened on the rotating pipe 51. Air is blown into the second air pipe 43 through the air tank 4, and air is blown into the support pipe 5 through the second air pipe 43. Air is blown into the rotating pipe 51 through the air inlets 511.

[0039] The dust collector housing 1 is equipped with an observation mirror 6 corresponding to the air inlet chamber. The filter element 14 inside the dust collector housing 1 can be easily observed through the observation mirror 6.

[0040] The implementation principle of a dust collector for cleaning a low-power filter element 14 according to an embodiment of this application is as follows: gas is transported into the dust collector through the air inlet pipe 11, and the gas enters the air outlet chamber through the filter element 14 and is sent out through the air outlet pipe 12. When the filter element 14 needs to be cleaned, air is blown into the first air pipe 26, which moves the connecting sleeve 23 and the cover plate 24 downward to block the air passage 131. Air is then blown into the connecting pipe 21, and the gas enters the main shaft 31, the connecting plate 32 and the side shaft 33. The gas is blown out through the air outlet 331 on the side shaft 33 to blow off the dust adhering to the filter element 14. At the same time, because the air outlet 331 on the side shaft 33 is eccentrically opened, the thrust during the air outlet 331 on the side shaft 33 drives the rotating blade 3 to rotate, thereby improving the cleaning efficiency of the filter element 14.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
