[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figures 1 to 7 , the present invention provides a technical solution:

[0036] An environmentally friendly waste gas dust removal device, comprising a treatment box 1, the upper end surface of the treatment box 1 is fixedly connected to an exhaust pipe 4, the lower end surface of the treatment box 1 is fixedly connected to an air intake pipe 5, the front end surface of the treatment box 1 is fixedly connected to a motor 2, the lower end surface of the treatment box 1 is symmetrically fixedly connected to a dust collection box 3, the rear end surface of the treatment box 1 is rotatably connected to a pulley 6, both sides of the pulley 6 are symmetrically provided with a pneumatic mechanism 9, the outer side of the pulley 6 is sleeved with a first belt 7 and a second belt 8, and the pulley 6 is transmission-connected to the pneumatic mechanism 9 through the first belt 7 and the second belt 8;

[0037] A filter cartridge 23 of a cylindrical structure is rotatably connected inside the treatment box 1, and baffle plates 17 are symmetrically distributed inside the filter cartridge 23. The rear end of the baffle plate 17 is fixed to the inner wall of the treatment box 1, and the upper and lower ends of the baffle plate 17 are arc-shaped structures and do not contact the filter cartridge 23. Baffle plates 3 24 are fixed at both sides of the filter cartridge 23 inside the treatment box 1, and baffle plates 1 10 are symmetrically fixed at the upper side of the filter cartridge 23 inside the treatment box 1, and a gap is reserved between the baffle plates 10 and 17 for the rotational displacement of the filter cartridge 23.

[0038] Specifically, a collecting chamber 11 is opened on both sides of the interior of the processing box 1 at the lower side of the baffle 10, and a discharge port 12 connected with the collecting chamber 11 is opened at the bottom of the processing box 1 at a position corresponding to the collecting chamber 11. The collecting chamber 11 is connected with the dust collecting box 3 through the discharge port 12, and the dust collecting box 3 is fixed to the processing box 1 by screws. An air inlet 13 is opened in the interior of the processing box 1 at a position corresponding to the air inlet pipe 5, and the air inlet pipe 5 is connected with the interior of the processing box 1 through the air inlet 13. The interior of the processing box 1 is fixedly connected with connecting rods 16 on both sides of the air inlet 13, and a buffer plate 15 is fixedly connected to the top of the connecting rod 16. The buffer plate 15 is designed with an arc-shaped structure and is distributed above the air inlet 13 and below the filter cartridge 23.

[0039] By adopting the above technical scheme, when working, the exhaust gas is first injected into the treatment box 1 through the air inlet pipe 5. The exhaust gas entering the treatment box 1 first contacts the buffer plate 15 on the air inlet 13. The exhaust gas is buffered by the buffer plate 15 and diffuses around along the arc surface of the buffer plate 15. Then the exhaust gas rises upward and contacts the lower side of the outside of the filter cartridge 23, and then passes through the bottom of the filter cartridge 23 for filtration and enters the filter cartridge 23. Then, it continues to rise and passes through the upper side of the outside of the filter cartridge 23 for secondary filtration and finally is discharged from the treatment box 1 through the exhaust port 14 and the exhaust pipe 4 to enter the next exhaust gas treatment process equipment. During the process of exhaust gas filtering by the filter cartridge 23, the exhaust gas continues to contact one place on the surface of the filter cartridge 23, which can easily cause the filter cartridge 23 to be blocked. Therefore, in actual use, the motor 2 can drive the transmission rod 19 to drive the connecting rod 20 to drive the filter cartridge 23 to rotate inside the treatment box 1, so that the exhaust gas contacts various positions on the surface of the filter cartridge 23.

[0040] Specifically, a connecting rod 20 is fixedly connected in an annular manner at equal distances inside the filter cartridge 23 near the front side. The other end of the connecting rod 20 is designed in an annular structure, and a transmission rod 19 is rotatably connected inside the annular end of the connecting rod 20. An electromagnet is embedded in the annular end of the connecting rod 20. The transmission rod 19 is made of a magnetic metal material. The front end of the transmission rod 19 is fixed to the output shaft of the motor 2, and the rear end of the transmission rod 19 is fixedly connected to a transmission rod 21. The rear end of the transmission rod 21 passes through the processing box 1 and is fixed to the pulley 16. A sealing ring is provided between the transmission rod 21 and the processing box 1.

[0041] By adopting the above technical solution, the dust adhesion area on the surface of the filter cartridge 23 will enter the collection chamber 11 as the filter cartridge 23 rotates and displaces. At this time, the electromagnet in the annular end of the connecting rod 20 is powered off, and the magnetic attraction force with the transmission rod 19 disappears. At this time, the motor 2 drives the transmission rod 19 to rotate at high speed without driving the connecting rod 20 to rotate. Then the rotation of the transmission rod 19 drives the transmission rod 21 to rotate.

[0042] Specifically, the pneumatic mechanism 9 includes a nozzle 18 that is fixed on the baffle plate 17 at an equal distance in an annular manner, and the nozzles 18 on the two baffle plates 17 are relatively distributed. The pneumatic mechanism 9 also includes a sleeve 92 fixed to the processing box 1, and the rear end surface of the sleeve 92 is rotatably connected to the pulley 91, and the two pulleys 91 are respectively connected to the pulley 6 through the first belt 7 and the second belt 8. The interior of the sleeve 92 is rotatably connected to a reciprocating screw rod 94, and the rear end of the reciprocating screw rod 94 is fixed to the pulley 91, and is located at the The reciprocating screw rod 94 in the sleeve 92 is externally spirally connected to an air plug plate 93, and the outer wall of the air plug plate 93 is designed to fit the inner wall of the sleeve 92. A connecting port 96 is provided at the front end of the sleeve 92, and an air duct 95 connected to the connecting port 96 is provided in the processing box 1. The air duct 95 extends to the baffle plate 17 and is connected to the nozzle 18. An air suction hole 97 is provided on the outside of the sleeve 92, and both the air suction hole 97 and the connecting port 96 have built-in one-way valves. The sleeve 92 and the air plug plate 93 are designed in a rectangular structure, and the two are movably connected.

[0043] By adopting the above technical solution, the rotation of the pulley 91 drives the reciprocating screw 94 to rotate. At this time, inside the sleeve 92, the air plug plate 93 connected to the reciprocating screw 94 in a spiral transmission is displaced forward and backward inside the sleeve 92. When the air plug plate 93 is displaced forward, the outside air is drawn into the sleeve 92 through the suction hole 97. When the air plug plate 93 is displaced backward, the compressed air enters the air duct 95 through the connecting port 96. Finally, the surface of the filter cartridge 23 is sprayed with high pressure through the nozzle 18 to blow and clean the dust attached to the surface of the filter cartridge 23. The blown dust is blown downward through the discharge port 12 into the dust collection box 3, so that the subsequent user can process the dust collection box 3.

[0044] Working principle: When working, the exhaust gas is first injected into the treatment box 1 through the air inlet pipe 5. The exhaust gas entering the treatment box 1 first contacts the buffer sheet 15 on the air inlet 13. The exhaust gas is buffered by the buffer sheet 15 and diffuses around along the arc surface of the buffer sheet 15. Then the exhaust gas rises upward and contacts the lower side of the outside of the filter cartridge 23, and then passes through the bottom of the filter cartridge 23 for filtration, enters the filter cartridge 23, and then continues to rise through the upper side of the outside of the filter cartridge 23 for secondary filtration. Finally, it is discharged from the treatment box 1 through the exhaust port 14 and the exhaust pipe 4 and enters the next exhaust gas treatment process equipment. During the process, the exhaust gas continuously contacts one place on the surface of the filter cartridge 23, which may easily cause the filter cartridge 23 to be blocked. Therefore, in actual use, the motor 2 can be used to drive the transmission rod 19 to drive the connecting rod 20 to drive the filter cartridge 23 to rotate inside the treatment box 1, so that the exhaust gas can contact various positions on the surface of the filter cartridge 23, and avoid the blockage caused by concentrated contact on one side of the filter cartridge 23. The dust filtered by the filter cartridge 23 adheres to the surface of the filter cartridge 23 and needs to be cleaned. Otherwise, the filter holes on the surface of the filter cartridge 23 will be blocked. Therefore, when the motor 2 rotates to change the position of the filter cartridge 23, the surface of the filter cartridge 23 is The dust adhesion area on the surface will enter the collection chamber 11 as the filter cartridge 23 rotates and displaces. At this time, the electromagnet in the annular end of the connecting rod 20 is powered off, and the magnetic attraction force with the transmission rod 19 disappears. At this time, the motor 2 drives the transmission rod 19 to rotate at high speed, but does not drive the connecting rod 20 to rotate. Then the transmission rod 19 rotates to drive the transmission rod 21 to rotate, and then drives the connecting rod 3 22 to rotate, and drives the pulley 1 6 to rotate. The pulley 1 6 drives the pulleys 2 91 on both sides to rotate through the first belt 7 and the second belt 8 respectively. Then the rotation of the pulley 2 91 drives the reciprocating screw 94 to rotate. The air block plate 93 connected to the reciprocating screw 94 in a spiral transmission inside the sleeve 92 is displaced forward and backward inside the sleeve 92. When the air block plate 93 is displaced forward, the outside air is drawn into the sleeve 92 through the air suction hole 97. When the air block plate 93 is displaced backward, the compressed air enters the air duct 95 through the connecting port 96. Finally, the surface of the filter cartridge 23 is sprayed with high pressure through the nozzle 18 to blow away the dust attached to the surface of the filter cartridge 23. The fallen dust is blown downward through the discharge port 12 into the dust collection box 3, so that the subsequent user can process the dust collection box 3.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
