[0020] The utility model provides a solid waste treatment screening device, including a screening mechanism 101, a feed pipe 102 and a purification component, the purification component including a hinge 103, a cover 104, a purification tank 105, an opening and closing door 106, an extension plate 107, a dust suction fan 108, a separator and a discharge component, the separator including an access pipe 109, an atomizing nozzle 110, a limiting bucket 111, a collection box 112, a heat conduction plate 113 and a heating plate 114, the discharge component including a discharge pipe 115 and an activated carbon filter 116, the above-mentioned solution solves the problem that harmful dust is generated when solid waste is crushed, and the dust leaks out from the feed port of the device, causing pollution to the environment.

[0021] For this specific embodiment, the feed pipe 102 is fixedly connected with the screening mechanism 101 and located above the screening mechanism 101. The purification assembly includes a hinge 103, a cover plate 104, a purification tank 105, an opening and closing door 106, an extension plate 107, a dust suction fan 108, a separation piece, and a discharge piece. The hinge 103 is fixedly connected with the feed pipe 102 and located outside the feed pipe 102. The cover plate 104 is hingedly connected with the feed pipe 102 and located outside the hinge 103. The purification tank 105 is detachably connected with the screening mechanism 101 and located outside the screening mechanism 101. The opening and closing door 106 is hingedly connected with the purification tank 105 and located inside the purification tank 105. The extension plate 107 is fixedly connected with the purification tank 105 and located outside the purification tank 105. The input end of the dust suction fan 108 is fixedly connected with the screening mechanism 101 and located above the extension plate 107. The output end of the dust suction fan 108 penetrates through the purification tank 105. The separation piece is fixedly connected with the purification tank 105 and located inside the purification tank 105. The discharge piece is fixedly connected with the purification tank 105 and located on the side of the purification tank 105 away from the extension plate 107. The screening mechanism 101 has been described in the prior art CN211801330U and is used for screening operation after solid waste is crushed. Therefore, no further description is given. Solid waste is poured into the screening mechanism 101 from the feed pipe 102. After pouring, the cover plate 104 is covered above the feed pipe 102 through the hinge 103, so as to prevent harmful dust generated from leaking out of the feed pipe 102. The screening mechanism 101 performs crushing operation on the solid waste. The extension plate 107 fixes the dust suction fan 108 outside the purification tank 105. The dust suction fan 108 operates to suck dust generated in the operation into the purification tank 105. The separation piece separates particles in the dust from air through atomization and facilitates cleaning and collection of the particulate matter dust through heating. The separated air is discharged after purification through the discharge piece. In this way, the problem that harmful dust leaks from the feed inlet of the device to cause environmental pollution can be effectively solved.

[0022] Among them, the access pipe 109 is fixedly connected with the purification tank 105 and penetrates through the purification tank 105. The atomizing nozzle 110 is fixedly connected with the access pipe 109 and located inside the purification tank 105. The limiting hopper 111 is fixedly connected with the purification tank 105 and located below the atomizing nozzle 110. The access pipe 109 is connected with an external water pump for water supply of the atomizing nozzle 110. The atomizing nozzle 110 atomizes and reduces harmful dust. The limiting hopper 111 converges water mist carrying dust to separate air from the carried dust.

[0023] Secondly, the collection box 112 is detachably connected to the purification tank 105 and is located below the limiting bucket 111. The heat conducting plate 113 is detachably connected to the collection box 112 and is located below the collection box 112. The heating disk 114 is fixedly connected to the purification tank 105 and is located below the heat conducting plate 113. The water mist carrying dust falls into the collection box 112. The heating disk 114 operates to heat the collection box 112 through the heat conducting plate 113, so that the water vapor in the collection box 112 evaporates. The collection box 112 can be taken out by opening the opening and closing door 106, thereby facilitating the collection and treatment of dust particles.

[0024] At the same time, the exhaust pipe 115 is fixedly connected to the purification tank 105 and is located on the side of the purification tank 105 away from the extension plate 107. The activated carbon filter 116 is fixedly connected to the exhaust pipe 115 and is located above the exhaust pipe 115. The exhaust pipe 115 discharges the air after dust settling into the activated carbon filter 116. The activated carbon filter 116 filters pollutants such as organic matter and heavy metals in the air, and discharges the air outward after filtering, thereby effectively improving the protection of the environment.

[0025] In addition, the purification tank 105 has a groove 117 adapted to the collection box 112 , and when the opening and closing door 106 is opened, the collection box 112 can be taken out and placed through the groove 117 .

[0026] A solid waste treatment and screening device according to the present embodiment is used, by providing the feed pipe 102 and the purification component. When in use, solid waste is fed into the screening mechanism 101 from the feed pipe 102. After being fed, the cover plate 104 is closed on top of the feed pipe 102 through the hinge 103, thereby preventing the generated harmful dust from leaking out from the feed pipe 102. The screening mechanism 101 crushes the solid waste, and the dust suction fan 108 operates to suck the dust generated by the operation into the purification tank 105. The access pipe 109 is connected to an external water pump, and the atomizing nozzle 110 sprays water mist to atomize and settle the harmful dust. The exhaust pipe 115 discharges the air after the dust settling to the activated carbon filter 11 6, the activated carbon filter 116 filters organic matter, heavy metals and other pollutants in the air, and discharges the air outward after the filtration is completed. The limiting bucket 111 gathers the water mist carrying dust, so that the water mist carrying dust falls into the collection box 112, and the heating disk 114 runs and heats the collection box 112 through the heat conducting plate 113 to evaporate the water vapor in the collection box 112. The collection box 112 can be taken out by opening the opening and closing door 106, and the dust particles in the collection box 112 can be collected and processed, so as to prevent the harmful dust generated in the solid waste screening operation from polluting the environment. By setting the purification component, the harmful dust can be effectively filtered and dusted, thereby improving the protection of the environment.
