[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0029] Combined with Figure 1-3A domestic waste incineration tail gas treatment device of this embodiment includes a treatment box 1, wherein a vertical partition 2 and a horizontal partition 3 are arranged in the treatment box 1, the bottom and left and right sides of the vertical partition 2 are sealed and connected to the inner wall of the treatment box 1, the horizontal partition 3 is arranged above the vertical partition 2 and is spaced apart from the vertical partition 2, the horizontal partition 3 is circular, and its outer peripheral side is sealed and connected to the inner wall of the treatment box 1, the two sides of the vertical partition 2 are respectively a first cavity 1a and a second cavity 1b, the first cavity 1a and the second cavity 1b are horizontally spaced apart, and the bottoms of the first cavity 1a and the second cavity 1b are both provided with a discharge pipe 4, The overlapping area of ​​the transverse partition 3 with the first cavity 1a is uniformly provided with a plurality of filter holes 3a, and the overlapping area of ​​the transverse partition 3 with the second cavity 1b is not provided with the filter holes 3a. An air inlet 5 and an exhaust port 6 are provided on the side of the processing box 1 close to the first cavity 1a, and the air inlet 5 is provided below the transverse partition 3, and the exhaust port 6 is provided above the transverse partition 3. A cleaning brush strip 7 is provided between the transverse partition 3 and the vertical partition 2, and the center of the cleaning brush strip 7 is aligned with the center of the transverse partition 3, the length of the cleaning brush strip 7 is the same as or close to the diameter of the transverse partition 3, and the height of the cleaning brush strip is the same as that of the vertical partition 2. The spacing between the transverse partition 3 and the vertical partition 2 is the same or close, and also includes a first driving structure for controlling the rotation of the cleaning brush strip 7. When the cleaning brush strip 7 rotates, the particle residue on the lower end surface of the transverse partition 3 can be cleaned, and the heavier particle residue will fall to the bottom of the first cavity 1a, and the lighter particle residue will enter the second cavity 1b under the action of the cleaning brush strip 7. Since there is no rising airflow in the second cavity 1b, the lighter particle residue will fall to the bottom of the second cavity 1b. The cleaning brush strip 7 is set to rotate once every period of time, and the cleaning brush strip 7 and the upper side of the vertical partition 2 are kept at the same time at other times. The edges overlap to isolate the first cavity 1a and the second cavity 1b as much as possible. Since there is no exhaust port in the second cavity 1b, the gas in the first cavity 1a will not flow into the second cavity 1b in large quantities. The cavity 1b also includes a closing structure for opening and closing the gap between the vertical partition 2 and the transverse partition 3. When cleaning the particle residue in the second cavity 1b, the closing structure can be used to close the gap between the vertical partition 2 and the transverse partition 3, thereby preventing the gas in the first cavity 1a from entering the second cavity 1b in large quantities and spraying out from the discharge pipe 4 when the discharge pipe 4 on the second cavity 1b is opened.

[0030] The domestic waste incineration tail gas treatment device can efficiently clean the particulate residues on the transverse partition 3, especially can prevent the lighter particulate residues from still blocking the filter hole 3a under the action of the airflow, and can clean the particulate residues collected in the second cavity 1b without stopping the machine.

[0031] As a preferred solution of the present utility model, the cleaning brush strip 7 includes a metal rod and a scraper or bristles arranged on the metal rod and in contact with the lower end surface of the transverse partition 3 .

[0032] As a preferred solution of the utility model, a plurality of baffles 8 are evenly distributed on the cleaning brush strip 7 along its length direction, and the baffles 8 are fixedly connected to the metal rod. The baffles 8 are arranged perpendicular to the cleaning brush strip 7 and contact the lower end surface of the partition 3. The baffles 8 are mainly arranged to prevent the particle residues cleaned by the cleaning brush strip 7 from moving toward the outer end of the cleaning brush strip 7, so as to ensure that the particle residues stably enter the second cavity 1b under the action of the cleaning brush strip 7.

[0033] As a preferred embodiment of the present utility model, the first driving structure includes a connecting shaft 9, which is rotatably connected to the diaphragm 3, the upper end of the connecting shaft 9 extends to the top of the diaphragm 3 and is connected to the first bevel gear 10, and the lower end of the connecting shaft 9 extends to the bottom of the diaphragm 3 and is connected to the cleaning brush strip 7; a second bevel gear 11 is meshed with the first bevel gear 10 for transmission; a first motor 12 is used to control the rotation of the second bevel gear 11, the motor 12 is connected to the second bevel gear 11 through an extension shaft 13, and the motor 12 is arranged away from the exhaust port 6. Through the arrangement of the extension shaft 13 and the bevel gear group, the motor 12 can be arranged as far away from the flow path of the exhaust gas as possible, thereby extending the service life of the motor 12.

[0034] As a preferred embodiment of the present invention, the closing structure includes a sealing plate 14 arranged in the second cavity 1b and abutting against the vertical partition 2 and the transverse partition 3, and a second driving structure for controlling the movement of the sealing plate 14. When the sealing plate 14 abuts against the vertical partition 2 and the transverse partition 3 at the same time, the gap between the vertical partition 2 and the transverse partition 3 is closed. Specifically, the sealing plate 14 is slidably connected to the vertical partition 2 up and down. The second driving structure includes a second motor 15 installed on the vertical partition 2; a screw 16, which is fixedly connected to the output shaft of the second motor 15; a fixed block 17, which is fixedly connected to the sealing plate 14 and threadedly cooperates with the screw 16. A thread groove cooperating with the screw 16 is provided in the fixed block 17. When the screw 16 rotates, it drives the fixed block 17 to move up and down, thereby realizing the up and down control of the sealing plate 14. Moreover, when cleaning the second cavity 1b, even if the second motor 15 is suddenly powered off, the sealing plate 14 can still be maintained in a closed state.

[0035] As a preferred solution of the utility model, in order to prevent particle residues from affecting the flexibility of the screw 16 during rotation, a telescopic sleeve 18 is provided on the outside of the screw 16 , one end of the telescopic sleeve 18 is connected to the second motor 15 , and the other end is connected to the fixed block 17 .

[0036] As a preferred solution of the utility model, a pressure sensor 19 is provided on the lower end surface of the diaphragm 3 and cooperates with the top of the sealing plate 14 to facilitate the user to judge the state of the sealing plate 14. Only when the pressure sensor 19 is supported by the sealing plate 14, the discharge pipe 4 on the second cavity 1b will be opened.

[0037] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
