Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, and more specifically, to a dust removal device for solid waste treatment. Background Art

The activated carbon filter layer 14 is provided between the air suction port 11 and the discharge hopper 3, that is, the activated carbon adsorption layer is provided above the upper opening of the discharge hopper 3 and below the air suction port 11. When solid waste enters from the feed port 31 and is discharged from the discharge port 32, dust is generated. The dust suction fan 13 generates negative pressure, so that the dust can move upward in the dust removal box 1. The activated carbon filter layer 14 has good adsorption performance due to its porous structure and high specific surface area, so that the dust is adsorbed by the activated carbon filter layer 14 when passing through the activated carbon filter layer 14.

[0036] A sewage outlet 17 is provided on the bottom side wall of the dust removal box 1 .

[0037] The cleaning device 2 is arranged in the dust removal box 1, and the cleaning device 2 includes a water storage tray 21, a plurality of water spray heads 22 arranged at the bottom of the water storage tray 21, a first cleaning motor 23 and a mounting block 24, and the first cleaning motor 23 is fixedly arranged at the upper end of the mounting block 24.

[0039] In addition, in this embodiment, a lifting device 4 for driving the cleaning device 2 to move up and down is provided in the dust removal box 1. The lifting device 4 can drive the cleaning device 2 to move up and down in the vertical direction. The lifting device 4 can use a structure such as a cylinder or an oil cylinder to drive the cleaning device 2 to move up and down. The lifting device 4 in this embodiment adopts the following structure.

[0040] The lifting device 4 includes a lifting screw 41 arranged in the vertical direction, a lifting slider 42 matched with the lifting screw 41, and a second lifting motor 43 driving the lifting screw 41 to rotate; a first gear 44 is arranged at the output end of the second lifting motor 43, and the second lifting motor 43 is arranged at the bottom of the dust removal box 1.

[0041] In this embodiment, two lifting screws 41 are provided, and the bottoms of the two lifting screws 41 are respectively connected to a second lifting motor 43, and the two lifting sliders 42 on the two lifting screws 41 are connected through the mounting block 24, and the cleaning device 2 is arranged on the mounting block 24.

[0043] The working principle of this embodiment is as follows: when in use, the crushed solid waste enters from the feed port 31 and is temporarily stored in the discharge hopper 3. Since a lot of dust will be generated when the solid waste is accumulated, which affects the later waste recovery, a dust suction fan 13 is provided. First, the force of the dust suction fan 13 causes the dust to be sucked upward by the air suction port 11. Most of the dust is adsorbed on the activated carbon filter layer 14. The activated carbon filter layer 14 has good adsorption performance due to its porous structure and high specific surface area. Then, clean water is led to the cleaning water tank 15 through the water guide pipe 16. The cleaning water tank 15 is connected to the connecting pipe 25. The water is stored in the water storage tray 21. Then the first cleaning motor 23 is started, and the output end of the first cleaning motor 23 and the water storage tray 21 are controlled to start rotating. During the rotation, the water spray head 22 at the bottom sprays water, so that the water sprayed on the side wall of the dust removal chamber can be more uniform, while expanding the range of water spraying, which plays a role in further dust removal. At the same time, the second lifting motor 43 controls The first gear 44 starts to rotate, and the first gear 44 drives the second gear 45 to rotate, and the second gear 45 drives the lifting screw 41 to rotate accordingly, so that the lifting slider 42 drives the water storage tray 21 to move up and down, which can not only clean the dust on the inner wall of the dust removal box 1, but also when the activated carbon filter layer 14 is saturated with adsorption, the height of the water storage tray 21 can be reduced to the minimum, so that the water sprayed by the water spray head 22 can spray and clean the activated carbon filter layer 14, and the sewage flows downward along the inner wall of the dust removal box 1, and finally the sewage is discharged from the sewage outlet 17, and the purified air is output from the air outlet pipe, sucked out by the dust suction fan 13, and discharged into the external environment.
