[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4The waste gas treatment device for environmental protection engineering shown in the figure comprises a filter box 1, a treatment box 2, a shunt pipe 3, a nozzle, activated carbon, an air guide pipe and a water pump. It should be noted that in the present embodiment, the installation method of the filter box 1, the treatment box 2, the shunt pipe 3, the nozzle, the activated carbon, the air guide pipe and the water pump can refer to the technical content adopted in a waste gas purification treatment device for environmental protection engineering disclosed in the Chinese patent with publication number CN213610690U in the prior art, which will not be repeated here. Two shunt pipes 3 are rotatably installed on the relative inner wall of the filter box 1, the nozzle is installed at the bottom of the two shunt pipes 3, the water pump is connected to the two shunt pipes 3 through a hose, a motor 4 is installed on the side of the filter box 1, and the filter box 1 is opened A movable chamber is provided, and a reciprocating screw rod 5 is rotatably installed on the relative inner wall of the movable chamber, one end of the reciprocating screw rod 5 is installed on the output shaft of the motor 4, and a rack 6 is threadedly sleeved on the reciprocating screw rod 5. One end of the two shunt pipes 3 extends into the movable chamber and is installed with a circular gear 7, and the two circular gears 7 are meshed with the rack 6. A groove is provided on the inner wall of the side of the filter box 1, and a reciprocating screw rod 29 is rotatably installed on the relative inner wall of the groove. An L-shaped block 11 is threadedly sleeved on the reciprocating screw rod 29, and a scraper 12 is installed on the bottom of the L-shaped block 11. Mounting holes are provided on the sides of the filter box 1 that are away from each other, and collecting boxes 13 are slidably installed in the two mounting holes. The reciprocating screw rod 29 is installed in coordination with the reciprocating screw rod 5 through a transmission mechanism.

[0023] By means of the above structure, when in use, the exhaust gas is filtered through the filter box 1, the treatment box 2, the activated carbon and the air duct. When the activated carbon needs to be cleaned, the water pump and the motor 4 are started first. The water pump output will cause water to spray out from the nozzle on the shunt pipe 3, and the motor 4 output will cause the reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 will cause the rack 6 to move back and forth. The reciprocating movement of the rack 6 will cause the circular gear 7 to rotate periodically. The periodic rotation of the circular gear 7 will cause the shunt pipe 3 to swing. The swing of the shunt pipe 3 will cause the nozzle to swing, thereby evenly spraying the surface of the activated carbon. At the same time, the rotation of the reciprocating screw 5 will cause the reciprocating screw 2 9 to rotate through the transmission mechanism. The rotation of the reciprocating screw 2 9 will cause the L-shaped block 11 to move. The movement of the L-shaped block 11 will cause the scraper 12 to move. The movement of the scraper 12 will cause the sediment on the activated carbon to hang in the collection box 13, thereby avoiding the sediment from affecting the filtration of the activated carbon, which is convenient for use.

[0024] like Figure 4As shown, telescopic rods are installed on the sides of the filter box 1 that are away from each other, movable plates 14 are installed on the ends of the two telescopic rods, and sealing plates 16 are installed on the bottoms of the two movable plates 14. Sealing holes are opened on the sides of the filter box 1 that are away from each other, and one end of the two sealing plates 16 respectively penetrates the two sealing holes and is tightly pressed against the two sides of the activated carbon, and extrusion plates are installed on the sides of the scraper 12 that are away from each other, and elastic mechanisms are provided on the sides of the two movable plates 14. The advantage of such an arrangement is that, through the arrangement of the telescopic rod, the movable plate 14 and the sealing plate 16, it is convenient to block the collecting box 13 to prevent water from flowing into the collecting box 13, and at the same time prevent the exhaust gas from flowing out of the installation hole after the collecting box 13 is pulled out.

[0025] Specifically, the movement of the scraper 12 will cause the extrusion plate to move, and the movement of the extrusion plate will squeeze the sealing plate 16 to move. At this time, the scraper 12 continues to move to scrape the sediment into the collection box 13. When not cleaned, the sealing plate 16 will contact the activated carbon under the action of the elastic mechanism, thereby blocking the installation hole.

[0026] like Figure 1 As shown, the elastic mechanism includes a spring 15 installed on the side of the movable plate 14, and the other end of the spring 15 is installed on the side wall of the filter box 1. The advantage of this arrangement is that through the arrangement of the spring 15, when the sealing plate 16 is not subjected to force, the sealing plate 16 is in contact with the activated carbon.

[0027] like Figure 3 As shown, the transmission mechanism includes a first bevel gear 8 sleeved on the reciprocating screw rod 1 5, one end of the reciprocating screw rod 2 9 extends into the movable cavity and is installed with a second bevel gear 10, and the first bevel gear 8 and the second bevel gear 10 are meshed with each other. The advantage of this arrangement is that through the arrangement of the first bevel gear 8 and the second bevel gear 10, when the reciprocating screw rod 1 5 rotates, the reciprocating screw rod 2 9 also rotates.

[0028] like Figure 3 As shown, guide rods are installed on the relative inner walls of the movable cavity and the relative inner walls of the groove, guide holes are opened on the side of the rack 6 and the side of the L-shaped block 11, and the two guide rods pass through the two guide holes respectively. The advantage of this arrangement is that the rack 6 and the L-shaped block 11 can be moved in the horizontal direction through the setting of the guide rods.

[0029] like Figure 2As shown, a partition 17 is installed on the relative inner wall of the treatment box 2, and two stirring rods 18 are rotatably installed on the bottom inner wall of the treatment box 2. Electromagnetic valves are provided on the two air ducts. A motor 19 is installed on the bottom of the treatment box 2, and the bottom end of one of the stirring rods 18 is installed on the output shaft of the motor 19. A through cavity is opened on the treatment box 2, and sprockets 20 are sleeved on the two stirring rods 18. The two sprockets 20 are engaged with a chain 21. The advantage of such an arrangement is that the treatment box 2 is divided into two parts through the arrangement of the partition 17, the stirring rod 18, the electromagnetic valve and the motor 19, the sprocket 20 and the chain 21. When the water needs to be replaced, the other side can still treat the exhaust gas, which is convenient for sustainable treatment of the exhaust gas.

[0030] Specifically, when in use, the two stirring rods 18 are rotated by the motor 19, the sprocket 20 and the chain 21. When the water needs to be replaced, the electromagnetic valve on one side is closed first, and then the water is replaced. At this time, the air duct on the other side can still work, so as to facilitate sustainable treatment of the exhaust gas.

[0031] like Figure 2 As shown, the nozzles on the two branch pipes 3 are staggered with each other. The advantage of such an arrangement is that the nozzles can spray the surface of the activated carbon evenly.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
