And the connecting rod will drive the ejector pin to displace upward, thereby lifting the bottom plate and driving the spare filter plate to displace upward. And the side of the spare filter plate will block the round hole of the connecting flange at the right end of the main housing, thereby causing the sealing column to displace upward and disengage from the second round hole of the sealing plate, so that the incoming dust-laden air passes through the water filtration and then through the spare filter plate. In this way, the dust treatment equipment can be maintained without shutting down the equipment generating dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Such as Figures 1-4As shown in the figure, an embodiment of the present application provides a low-concentration dust treatment device, including:

[0029] A main housing 1, a filter housing 6 is fixedly provided at the lower right end of the main housing 1, and a detachable top plate 9 is fixedly connected to the upper end of the filter housing 6 by bolts. A connecting pipe 7 is inserted and connected to the left side of the upper end of the top plate 9, and the air outlet of the connecting pipe 7 is connected to the upper right end of the main housing 1 through a flange 8;

[0030] A common filter plate 27, there are multiple common filter plates 27, and a mounting strip 30 is fixedly connected to the upper end of the outer frame of the common filter plate 27. The mounting strip 30 is inserted into the mounting groove 29 opened at the lower end of the connecting plate 11. The left end of the connecting plate 11 is fixedly connected to a pressing baffle 26, and a number of first round holes 28 are vertically penetrated through the pressing baffle 26. The upper end of the pressing baffle 26 is fixedly connected to the upper side wall on the left side of the inner cavity of the filter housing 6;

[0031] A cleaning sealing plate 23 is movably inserted into the internal part of a storage housing 5 arranged on the left side of the filter housing 6. The lower end of the cleaning sealing plate 23 is fixedly connected with first springs 24 at equal intervals. The upper right side of the cleaning sealing plate 23 is fixedly connected with a "Z"-shaped transmission rod 25. When the pressing baffle 26 is installed, the transmission rod 25 is pressed to drive the cleaning sealing plate 23 to be stored in the storage housing 5, and a groove matching the transmission rod 25 is opened at the upper right side of the storage housing 5;

[0032] A spare filter plate 17, the lower end of the spare filter plate 17 is fixedly connected with a bottom plate 15. The lower end of the bottom plate 15 is uniformly fixedly connected with sealing columns 18. The sealing columns 18 are correspondingly movably inserted into second round holes opened in a sealing plate 16. The four sides of the sealing plate 16 are fixedly connected to the lower inner side wall of the main housing 1. A cylindrical plate 14 is fixedly connected to the middle of the spare filter plate 17. The upper end of the cylindrical plate 14 is fixedly connected with a second spring 13. A top column 19 is movably inserted into the middle of the sealing plate 16. The lower right side of the top column 19 is fixedly connected to the upper left part of the cleaning sealing plate 23 through a connecting rod 22.

[0033] Specifically: brackets are provided on the left and right sides of the lower end of the main housing 1;

[0034] The elastic coefficient of the first spring 24 is greater than that of the second spring 13. In this way, when the upper end of the cleaning sealing plate 23 is not pressed by the pressing baffle 26, the cleaning sealing plate 23 will move upward and overcome the elastic force of the second spring 13;

[0035] Both the common filter plate 27 and the spare filter plate 17 adopt the existing filter dust filter meshes on the market.

[0036] Such as Figure 2As shown: A limiting slide rod 20 is movably inserted into the inner side of the lower part of the top column 19, and the lower end of the limiting slide rod 20 is fixedly connected to the lower end of the inner cavity of the main housing 1.

[0037] Specifically: The limiting slide rod 20 can make the up and down displacement of the top column 19 more stable.

[0038] As Figure 2 shown: A number of third round holes are uniformly drilled through the bottom plate 15 up and down.

[0039] Specifically: When the spare filter plate 17 is filtering, the third round holes can be connected, so that the dust gas can pass through the spare filter plate 17. The spare filter plate 17 is only used when the common filter plate 27 is being cleaned or maintained.

[0040] As Figure 2 shown: The upper end surface of the storage housing 5 is higher than the lower end surface of the inner cavity of the main housing 1, and an extrusion flat plate is provided at the relative position above the inner cavity of the main housing 1 and the storage housing 5.

[0041] Specifically: The storage housing 5 can store the cleaning sealing plate 23.

[0042] As Figure 2 shown: The lower end surface and the front and rear side surfaces of the common filter plate 27 are in extrusion sealing with the inner side wall of the filter housing 6.

[0043] Specifically: After the common filter plate 27 is installed, the lower end surface and the front and rear side surfaces are in extrusion sealing with the inner side wall of the filter housing 6.

[0044] As Figure 1 and Figure 2 shown: A plurality of air inlet pipes 10 are fixedly inserted into the lower part of the left end of the main housing 1, the lower part and the upper part of the front end of the main housing 1 are respectively fixedly inserted with a water inlet pipe 3 and a water outlet pipe 2, valves are installed on both the water inlet pipe 3 and the water outlet pipe 2, and a transparent observation window 4 is fixedly inlaid on the lower part of the front side wall of the main housing 1, and an air outlet pipe 12 is fixedly inserted on the left side of the upper side wall of the main housing 1.

[0045] Specifically: The transparent observation window 4 can observe the turbidity state of the filtered water inside the main housing 1, and the water can be replaced in time through the water inlet pipe 3 and the water outlet pipe 2.

[0046] As Figure 2 shown: The air outlet end of the air inlet pipe 10 is fixedly connected to a gas distribution housing 21, a number of small round holes are uniformly provided on the gas distribution housing 21, and the upper end of the gas distribution housing 21 is lower than the upper end of the storage housing 5.

[0047] Specifically: The gas separation housing 21 can divide the gas into several portions, enabling the gas to be fully mixed and filtered with water. After a period of time, the water inside the main housing 1 needs to be replaced and is discharged through the outlet pipe 2.

[0048] Principle of use: First, water is injected into the interior of the main housing 1 through the inlet pipe 3, such that the water floods over the gas separation housing 21 but does not flood over the upper end face of the storage housing 5. Then, dust gas is introduced into the interior of the main housing 1 through the inlet pipe 10. The dust gas is first filtered by the water, thereby filtering out 90% of the dust. Then, it passes through the first round hole 28 on the extrusion baffle 26 and is filtered by multiple common filter plates 27, filtering all the dust in the air. The filtered gas is introduced into the upper part of the inner cavity of the main housing 1 through the connecting pipe 7 and above the spare filter plate 17, and then discharged through the outlet pipe 12.

[0049] When it is necessary to clean the common filter plate 27, the bolts on the flange 8 and the top plate 9 are disassembled by an external tool, and then the top plate 9 is disassembled to disassemble the lower filter plate 27. As the top plate 9 is disassembled and displaced upward, the elastic force of the first spring 24 causes the cleaning sealing plate 23 to be displaced upward until the cleaning sealing plate 23 is upwardly pressed against and fitted to the lower end of the extrusion flat plate, thereby sealing the filter housing 6.

[0050] And the connecting rod 22 will drive the ejector pin 19 to be displaced upward, thereby lifting the bottom plate 15 and driving the spare filter plate 17 to be displaced upward. And the side of the spare filter plate 17 will block the round hole of the connecting flange 8 at the right end of the main housing 1, thereby causing the sealing column 18 to be displaced upward and disengaging from the second round hole of the sealing plate 16, so that the introduced dust-laden air is filtered by the water and then passes through the spare filter plate 17 and is discharged through the outlet pipe 12.

[0051] After the common filter plate 27 is cleaned and installed, the cleaning sealing plate 23 is displaced downward, driving the ejector pin 19 to be displaced downward. Under the action of the second spring 13, the bottom plate 15 and the filter plate 17 are displaced downward, thereby causing the sealing column 18 to be displaced downward and inserted into the second round hole of the sealing plate 16 to achieve sealing, and the ventilation path of the common filter plate 27 is used again for filtering dust.

[0052] The above are only specific embodiments of the present application, enabling those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features claimed in the present application.
