DETAILED DESCRIPTION

[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 1-4 The dust removal device for waste gas treatment shown in the figure comprises a dust removal box 1, an activated carbon adsorption filter, a nozzle and a water pump. It should be noted that in this embodiment, the installation method of the dust removal box 1, the activated carbon adsorption filter, the nozzle and the water pump can refer to the technical content adopted in a dust removal device for industrial waste gas treatment disclosed in the Chinese patent with publication number CN217855297U in the prior art, which will not be repeated here. A motor 16 is installed on the side of the dust removal box 1, and a reciprocating screw rod 17 is rotatably installed relative to the inner wall of the dust removal box 1. One end of the reciprocating screw rod 17 is installed on the output shaft of the motor 16, and a threaded block 18 is threadedly sleeved on the reciprocating screw rod 17. A moving block 19 is installed at the bottom of the threaded block 18. The nozzle is installed Installed at the bottom of the moving block 19, the water pump is connected with the nozzle through a shunt pipe, a partition block 11 is installed on the top inner wall of the dust removal box 1, sliding holes are provided on the sides of the dust removal box 1 that are away from each other, mounting frames 8 are slidably installed in the two sliding holes, and dust-proof nets 9 are installed on the opposite inner walls of the two mounting frames 8 through bolts, a fixed block 2 is installed on the side of the dust removal box 1, a telescopic hydraulic cylinder 3 is installed on the side of the fixed block 2, and a moving frame 4 is installed on the output end of the telescopic hydraulic cylinder 3, a through hole compatible with the moving frame 4 is opened on the side of the dust removal box 1, a connecting ring plate 5 is installed on the side of the moving frame 4, an air outlet pipe and an air inlet pipe are respectively installed on the other side of the dust removal box 1 and the side of the connecting ring plate 5, and an elastic sealing mechanism is provided on the dust removal box 1.

[0023] With the above structure, when in use, the exhaust gas is first discharged into the dust removal box 1 through the air intake pipe, the exhaust gas will first be filtered through the dustproof net 9, and then the water pump and the motor 16 are turned on, the water pump output will cause water to be sprayed out from the nozzle, the motor 16 output will cause the reciprocating screw rod 17 to rotate, the reciprocating screw rod 17 rotation will cause the threaded block 18 to move, the threaded block 18 movement will cause the moving block 19 to move, the moving block 19 movement will cause the nozzle to move, and then the exhaust gas is evenly sprayed, and the dust removal effect is better. When the dustproof net 9 needs to be replaced, the telescopic hydraulic cylinder 3 is first extended and retracted, and the contraction of the telescopic hydraulic cylinder 3 will cause the moving frame 4 to move. The movement of the movable frame 4 will move the air intake pipe through the connecting ring plate 5. When the movable frame 4 moves to a certain position, under the action of the elastic sealing mechanism and the partition block 11, the exhaust gas will only pass through the dust-proof net 9 on one side. At this time, the other mounting frame 8 is pulled out to replace the dust-proof net 9. When the replacement is completed, the movable frame 4 is moved by the telescopic hydraulic cylinder 3 to allow the exhaust gas to pass through the newly replaced dust-proof net 9. At this time, the above operation is repeated to replace the other dust-proof net 9, and the dust-proof net 9 can be replaced without stopping the exhaust gas transportation, thereby facilitating sustainable dust removal of the exhaust gas and facilitating use.

[0024] like Figure 4 As shown, the elastic sealing mechanism includes two movable chambers opened on the dust removal box 1 and connected with the through hole, and sealing plates 6 are slidably installed in the two movable chambers. Two springs 7 are installed on the sides of the two sealing plates 6, and the other ends of the two springs 7 on the same side are installed on the side inner wall of the movable chamber. The advantage of this arrangement is that through the arrangement of the sealing plates 6 and the springs 7, the sealing plates 6 are always in contact with the sides of the movable frame 4, thereby preventing exhaust gas from flowing out of the through hole.

[0025] like Figure 1 As shown, an electric liquid pushing rod 14 is installed on the top of the dust removal box 1, and a movable plate 15 is installed on the output end of the electric liquid pushing rod 14. Two slide bars 12 are installed on the bottom of the movable plate 15. Two slide holes are opened on the top of the dust removal box 1. The bottom ends of the two slide bars 12 respectively pass through the two slide holes and are installed with cleaning plates 13. The advantage of this arrangement is that the dustproof net 9 is easy to clean through the arrangement of the slide bars 12, the cleaning plates 13, the electric liquid pushing rod 14, and the movable plate 15.

[0026] Specifically, the output of the electric push rod 14 will cause the moving plate 15 to rise and fall, and the rising and falling of the moving plate 15 will cause the sliding bar 12 to rise and fall back and forth, and the sliding bar 12 to fall back and forth will cause the cleaning plate 13 to rise and fall back and forth, thereby cleaning the dustproof net 9.

[0027] like Figure 3As shown, the sides of the dust collector 1 that are away from each other are both equipped with rotating plates 22 through a rotating shaft, and the sides of the two rotating plates 22 are provided with mounting holes, and fixing bolts 23 are movably installed in the two mounting holes. The sides of the dust collector 1 that are away from each other are both provided with threaded grooves, and the ends of the two fixing bolts 23 are respectively threadedly installed in the two threaded grooves. The advantage of this arrangement is that through the arrangement of the rotating plate 22 and the fixing bolts 23, it is convenient to limit the installation frame 8, thereby preventing the dustproof net 9 from moving.

[0028] like Figure 4 As shown, collecting boxes 10 are installed on the sides of the two mounting frames 8, and the sides of the dust removal box 1 away from each other are provided with through holes adapted to the collecting boxes 10. The advantage of such an arrangement is that the collecting boxes 10 facilitate the collection of cleaned impurities and are convenient to use.

[0029] like Figure 4 As shown, a guide rod is installed on the relative inner wall of the dust removal box 1, and a guide hole is opened on the side of the threaded block 18, and the guide rod passes through the guide hole. The advantage of this arrangement is that the threaded block 18 can move in the horizontal direction through the setting of the guide rod.

[0030] like Figure 2 and Figure 4 As shown, a baffle hole is opened on the side of the dust removal box 1, and a baffle 21 is slidably installed in the baffle hole. One side of the baffle 21 extends into the dust removal box 1 and is installed with a limiting plate 20. The advantage of this arrangement is that the activated carbon adsorption filter can be easily blocked by the arrangement of the baffle 21 and the limiting plate 20.

[0031] Specifically, when the activated carbon adsorption filter needs to be replaced, the baffle 21 is first pushed so that the limit plate 20 contacts the inner wall of the other side of the dust removal box 1, thereby blocking the activated carbon adsorption filter. At this time, the water sprayed from the nozzle is blocked by the baffle 21, and then the activated carbon adsorption filter is replaced. When the replacement is completed, the baffle 21 is pulled out again. At this time, the water flows through the new activated carbon adsorption filter, thereby facilitating the replacement of the activated carbon adsorption filter while filtering the exhaust gas.

[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.
