Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] As shown in Figure 1 , Figure 3 and Figure 4 , a zeolite wheel waste gas treatment device includes a zeolite wheel body 1 and a ventilation box 2 fixed to the intake end of the zeolite wheel body 1. The ventilation box 2 is connected to an external waste gas input device to realize waste gas input. The zeolite wheel body 1 is a prior art and can perform an adsorption - concentration - desorption three - stage treatment on the waste gas entering through the ventilation box 2. An inclined intercepting net 3 is installed inside the ventilation box 2, and the included angle range formed by the intercepting net 3 and the inner bottom of the ventilation box 2 is 45° - 60°, so that the side of the intercepting net 3 away from the zeolite wheel body 1 of the ventilation box 2 is at a relatively lower position compared to the other side. An inclined movable rod 4 is arranged inside the ventilation box 2, and the inclination of the movable rod 4 is the same as that of the intercepting net 3.

[0026] As shown in Figure 1 , Figure 3 and Figure 4, on one side of the movable rod 4, there is a laterally connecting rod 5 fixedly connected in a linear array. One end of the laterally connecting rod 5 is fixedly connected with a cleaning brush 6 arranged obliquely. The inclination of the cleaning brush 6 is the same as that of the intercepting net 3. The bristles of the cleaning brush 6 are in contact with the surface of the intercepting net 3 and can move along the surface of the intercepting net 3. A sealing cover 7 is fixedly connected to the top of the ventilation box 2. The top of the movable rod 4 penetrates through the ventilation box 2 and extends into the interior of the sealing cover 7.

[0027] As Figure 1 , Figure 3 and Figure 4 , on the top of the ventilation box 2, there is a top plate 8. A sealing gasket 801 is fixedly connected to the bottom of the top plate 8. The top of the intercepting net 3 penetrates through the ventilation box 2 and is fixedly connected to the bottom of the sealing gasket 801. There are fixing bolts 802 on the top plate 8. The fixing bolts 802 can pass through the top plate 8 and be threadedly connected to the ventilation box 2. There are corresponding screw holes on the top plate 8 to install and fix the top plate 8 to the ventilation box 2, and the sealing gasket 801 provides the sealing ability above the ventilation box 2;

[0028] By removing the fixing bolts 802, the intercepting net 3 can be pulled outwards in the inclined direction, which is convenient for taking out the intercepting net 3 for cleaning or replacement.

[0029] As Figure 1 , Figure 2 and Figure 4 , a communication groove 9 is formed at the bottom of the ventilation box 2. A collection bin 10 is installed below the communication groove 9 at the bottom of the ventilation box 2. The collection bin 10 can be installed at the bottom of the ventilation box 2 through a bolt structure.

[0030] As Figure 1 , Figure 3 and Figure 4 , a piston 11 is fixedly connected to the top of the movable rod 4. A tension spring 12 is fixedly connected between the piston 11 and the top of the ventilation box 2. The tension spring 12 has an upward thrust on the piston 11. The tension spring 12 is sleeved on the outer surface of the movable rod 4. A limiting ring 20 is fixedly connected above the piston 11 in the sealing cover 7. The limiting ring 20 can limit the upward movement of the movable rod 4 and the piston 11. An adjustment cavity 21 is formed above the limiting ring 20 inside the sealing cover 7.

[0031] As Figure 1 , Figure 3 and Figure 4 , a pressurized air pump 13 is fixedly installed on the top of the ventilation box 2. The pressurized air pump 13 is a prior art, externally powered, and can be controlled by an external switch. An intake pipe 14 is installed at the intake port of the pressurized air pump 13. One end of the intake pipe 14 is communicated with the ventilation box 2. An outlet pipe 15 is installed at the outlet port of the pressurized air pump 13. One end of the outlet pipe 15 is communicated with the adjustment cavity 21.

[0032] As Figure 1 , Figure 3 and Figure 4 , a circulation pipe 16 is fixedly connected to the sealing cover 7. One end of the circulation pipe 16 is fixedly connected to the ventilation box 2. An electromagnetic valve 17 is installed on the circulation pipe 16. The electromagnetic valve 17 is a prior art, externally powered, and controlled by an external switch.

[0033] The working principle of a zeolite wheel waste gas treatment device provided by the present utility model is as follows:

[0034] When waste gas is conveyed from the ventilation box 2 to the zeolite wheel body 1, large particulate impurities in the waste gas are filtered out by the intercepting net 3 to prevent the large particulate impurities from clogging the zeolite pores. Since the intercepting net 3 is inclined, on the one hand, the contact area between the surface of the intercepting net 3 and the waste gas can be increased, and on the other hand, some of the filtered impurities can directly fall into the collection bin 10;

[0035] When it is necessary to clean the impurities on the surface of the intercepting net 3, the pressurized air pump 13 conveys the waste gas inside the ventilation box 2 to the adjustment chamber 21 under pressure through the air inlet pipe 14. The increased air pressure inside the adjustment chamber 21 is used to push the piston 11. The piston 11 drives the cleaning brush 6 to move downward through the movable rod 4 and the transverse connecting rod 5. Then the electromagnetic valve 17 is opened, and the waste gas inside the adjustment chamber 21 can flow back to the inside of the ventilation box 2 through the circulation pipe 16. The tension spring 12 stretches to push the piston 11, and the piston 11 drives the cleaning brush 6 to move upward through the movable rod 4 and the transverse connecting rod 5, realizing the reciprocating up and down movement of the cleaning brush 6, which can clean the impurities on the surface of the intercepting net 3, making the impurities fall into the collection bin 10, and reducing the frequency of disassembling and cleaning the intercepting net 3;

[0036] At the same time, the waste gas flows between the adjustment chamber 21 and the ventilation box 2 without causing air disturbance to the external air.

[0037] Compared with the related technology, a zeolite wheel waste gas treatment device provided by the present utility model has the following beneficial effects:

[0038] By setting the inclined intercepting net 3 and cooperating with the pressurized air pump 13, all the cleaning brushes 6 are attached to the surface of the intercepting net 3 and move obliquely. Not only can the impurities on the surface of the intercepting net 3 be cleaned, and the cleaned impurities directly fall from the inclined surface, facilitating the collection of impurities, but also the cleaning device can be started or stopped freely, reducing the wear between devices, and there is no need for a rotary sealing structure during the cleaning process, having a longer service life and effectively avoiding waste gas leakage.

[0039] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
