Description
Technical Field
[0001] The utility model relates to the technical field of dust removal equipment, in particular to a filter absorber with a dust removal function. Background Art
[0002] Patent publication number CN216769671 U discloses a civil air defense filter absorber with a dust removal function, which relates to the field of civil air defense filter absorbers. A dust removal box is provided with a tube body connected to the air inlet pipe and the air inlet, and multiple layers of inclined single-layer dust filters and double-layer dust filters are provided toward the middle of the tube body. Multiple single-layer dust filters and double-layer dust filters are arranged at equal distances. Single-layer dust filters are located on both sides of the tube body, and double-layer dust filters are located between the single-layer dust filters. A return air duct for air flow return is formed between adjacent double-layer dust filters. The dust-laden air flow first passes through the single-layer dust filter and the windward filter to intercept dust, and the dust-laden air flow is guided from one half cavity of the tube body to the other half cavity through the wind shield, and then the dust-laden air flow is refluxed to a certain extent in the backward direction through the return air duct, so that it is intercepted by the leeward filter again, thereby repeatedly achieving the dust interception effect in a tube body of limited length, thereby improving the dust interception efficiency.
[0003] The dust filtered by the filter will accumulate or deposit on one side of the filter. When the air flow passes through the filter again, the dust deposited there will be lifted up and the dust will attach to the filter again. The more dust accumulates, the worse the filtering effect of the filter will be, and the more difficult it will be to clean the filter. Utility Model Content
[0004] The purpose of the utility model is to provide a filter absorber with a dust removal function.
[0005] The technical problem solved by the present invention is that dust deposited on one side of the filter will be lifted up by the passing airflow and reattached to the filter, affecting the filtering effect of the filter and increasing the difficulty of cleaning the filter.
[0006] The utility model can be realized through the following technical solutions: it includes an air intake pipe fixedly connected to one side of the dust collector box, a limit plate fixedly installed in the inner cavity of the dust collector box, a connecting pipe slidingly installed through the limit plate, a filter screen fixedly installed on the side of the connecting pipe adjacent to the air intake pipe, a number of springs fixedly installed between the connecting pipe and the limit plate, a dust reduction mechanism installed in the inner cavity of the dust collector box between the connecting pipe and the air intake pipe, a pair of cam plates rotatably installed in the inner cavity of the dust collector box adjacent to the connecting pipe, and a transmission component installed on the top of the dust collector box to cause the dust reduction mechanism to intermittently spray atomized liquid.
[0007] A further technical improvement of the present invention is that a brush is fixedly mounted on one side of the outer peripheral wall of the communicating pipe adjacent to the filter screen, and the brush fits in contact with the inner peripheral wall of the dust removal box.
[0008] Furthermore, a side of the dust removal box away from the air inlet pipe is fixedly connected to a connecting pipe, a side of the connecting pipe away from the dust removal box is fixedly connected to a filter, and a side of the filter away from the connecting pipe is fixedly connected to an air outlet pipe.
[0009] Furthermore, the dust reduction mechanism includes a drain pipe fixedly connected to the top of the inner cavity of the dust removal box, a number of atomizing nozzles are installed on the drain pipe, a water tank fixedly installed on the top of the dust removal box and fixedly connected to the top of the drain pipe, a one-way valve is installed between the water tank and the drain pipe to promote the unidirectional flow of liquid from the water tank to the drain pipe, a piston cylinder fixedly installed on the top of the dust removal box and fixedly connected to the drain pipe, and a piston rod is slidably installed through the side of the piston cylinder away from the drain pipe.
[0010] Furthermore, the transmission assembly includes a rotating plate rotatably installed through the top of the dust removal box, and a push-pull plate is rotatably installed on the end of the rotating plate away from the rotating shaft, and the end of the push-pull plate away from the rotating plate is rotatably connected to the end of the piston rod away from the piston cylinder.

The liquid is sprayed in an atomized state through the drain pipe onto the dust shaken off the filter to reduce the dust, prevent the passing airflow from lifting the dust back to the windward side of the filter, and reduce the difficulty of cleaning the filter.
[0014] 2. This application uses a rotating cam plate to intermittently knock on the connecting pipe, causing the connecting pipe to vibrate left and right under the action of several springs to shake off the dust filtered on the windward side of the filter screen, preventing the filter screen from being blocked by dust too quickly.

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0022] See also Figure 1-4 As shown, this embodiment provides a filter absorber with a dust removal function, including a dust box 1, one side of the dust box 1 is fixedly connected to an air inlet pipe 2, the other side of the dust box 1 is fixedly connected to a connecting pipe 3, the side of the connecting pipe 3 away from the dust box 1 is fixedly connected to a filter 4, and the side of the filter 4 away from the connecting pipe 3 is fixedly connected to an air outlet pipe 5, a limit plate 6 is fixedly installed on the inner cavity of the dust box 1, a connecting pipe 7 is slidably installed through the limiting plate 6, a filter screen 8 is fixedly installed on the side of the connecting pipe 7 adjacent to the air inlet pipe 2, a number of springs 9 are fixedly installed between the connecting pipe 7 and the limiting plate 6, a brush 10 is fixedly installed on the side of the outer peripheral wall of the connecting pipe 7 adjacent to the filter screen 8, the brush 10 is in contact with the inner peripheral wall of the dust box 1, a dust reduction mechanism is installed at a position between the connecting pipe 7 and the air inlet pipe 2 in the inner cavity of the dust box 1, and a pair of cam plates 11 are rotatably installed at a position of the inner cavity of the dust box 1 adjacent to the connecting pipe 7;
[0023] The dust suppression mechanism includes a drain pipe 12 fixedly connected to the top of the inner cavity of the dust removal box 1, and a plurality of atomizing nozzles are installed on the drain pipe 12. A water tank 13 fixedly installed on the top of the dust removal box 1 and fixedly connected to the top of the drain pipe 12 is installed. A one-way valve (not shown in the figure) is installed between the water tank 13 and the drain pipe 12 to facilitate the unidirectional flow of liquid from the water tank 13 to the drain pipe 12. A piston cylinder 14 fixedly installed on the top of the dust removal box 1 and fixedly connected to the drain pipe 12 is installed. A piston rod 15 is slidably installed on the side of the piston cylinder 14 away from the drain pipe 12.
[0024] When the piston rod 15 is pulled toward the outside of the piston cylinder 14, the piston rod 15 will draw the liquid in the water tank 13 into the piston cylinder 14. At this time, when the piston rod 15 is pushed toward the inside of the piston cylinder 14, the piston rod 15 will squeeze the liquid in the piston cylinder 14 into the drain pipe 12, and the liquid will be sprayed in the form of atomization through the multiple atomizing nozzles on the drain pipe 12 into the space between the filter 8 and the air inlet pipe 2 in the inner cavity of the dust removal box 1, so as to reduce the dust in the space, prevent the airflow from passing through here and carrying dust to the surface of the filter 8, thereby reducing the risk of clogging the filter 8;
[0025] A rotating plate 16 is rotatably installed at the top of the dust removal box 1 near the piston rod 15. A driving motor for driving the rotating plate 16 is installed on the dust removal box 1. The rotating shaft of the rotating plate 16 and the rotating shaft of the cam plate 11 are driven by a pulley. A push-pull plate 17 is rotatably installed on the end of the rotating plate 16 away from the rotating shaft. The end of the push-pull plate 17 away from the rotating plate 16 is rotatably connected to the end of the piston rod 15 away from the piston cylinder 14.
[0026] When the rotating plate 16 rotates, it will drive the cam plate 11 to rotate synchronously through the pulley. The rotating cam plate 11 will intermittently knock on the connecting pipe 7 to shake off the dust on the surface of the filter screen 8 on the connecting pipe 7. When the cam plate 11 knocks the connecting pipe 7, the spring 9 is in a stressed state. When the cam plate 11 is disengaged from the action on the connecting pipe 7, the stressed state of the spring 9 is released, and the connecting pipe 7 is driven to vibrate left and right until the spring 9 rebounds to a natural state. In this process, the dust on the surface of the filter screen 8 will also be shaken off. In the process of the connecting pipe 7 moving to the left, the dust that falls on the windward side of the filter screen 8 will be swept into the range of the drain pipe 12 spraying atomized liquid, to prevent the dust that has just fallen from the filter screen 8 from not being subjected to dust reduction treatment. While the rotating plate 16 rotates, it will also drive the piston rod 15 to be pulled back and forth in the piston cylinder 14 through the push-pull plate 17 to promote the liquid in the water tank 13 to be transported to the drain pipe 12.
[0027] When the utility model is in use, the dust-laden airflow first enters the dust removal box 1 through the air inlet, and the piston rod 15 that is pulled back and forth in the piston cylinder 14 will intermittently transport the liquid in the water tank to the drain pipe 12, so that the drain pipe 12 intermittently sprays the atomized liquid into the dust removal box 1 through a plurality of atomizing nozzles. When the dust-laden airflow passes through the spray, it will undergo a certain degree of atomization and dust reduction, and then pass through the filter 8, thereby filtering the dust on the windward side of the filter 8. In this process, the cam plate 11 will intermittently press the connecting pipe 7. The knocking is performed to prompt the connecting pipe 7 to drive the filter 8 to vibrate left and right under the restriction of the limit plate 6, thereby shaking off the dust filtered on the filter 8. The shaken dust is cleaned by the brush 10 and moved to the range of the drain pipe 12 spraying the atomized liquid, so as to be atomized and dust-reduced to prevent the dust from being lifted up to the surface of the filter 8 by the air flow again, reducing the risk of clogging the windward side of the filter 8. The airflow after dust removal will enter the filter 4 through the connecting pipe 3, and then be discharged through the outlet pipe 5 after being processed by the filter 4.
[0028] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
