A guide plate is fixedly connected to the side of the support plate. The position of the guide plate corresponds to the position of the conveyor belt. A scraper is fixedly connected to the side of the support plate. The upper end of the scraper overlaps the lower surface of the conveyor belt.

[0007] In a preferred embodiment, a first sprocket is fixedly connected to the surface of the first shaft, a chain is attached to the surface of the first sprocket, and a second sprocket is fixedly connected to the surface of the second shaft.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a hazardous waste landfill pretreatment device, including a base 1, a screening component 2, and a crushing component 3. The screening component 2 is fixedly connected to the upper end of the base 1. The screening component 2 is used to screen the crushed hazardous waste and filter out the water in the hazardous waste. The screening component 2 includes a support plate 201, which is fixedly connected to the upper surface of the base 1. There are two sets of support plates 201, which are symmetrically arranged on the upper surface of the base 1. One set of support plates 201 has a first fixed platform 202 fixedly connected to its side. A first forward and reverse motor 203 is fixedly connected to the upper surface of the first fixed platform 202. The other end of the output shaft of the first forward and reverse motor 203 is fixedly connected to a first rotating shaft 204. The first rotating shaft 204 is connected to the surface of the support plate 201 through a bearing. A first transmission roller 205 is fixedly connected to the surface of the first rotating shaft 204. The first transmission roller 205 is made of permanent magnet. A conveyor belt 20 is attached to the surface of the first transmission roller 205. 6. A second rotating shaft 207 is connected to the inner wall of the support plate 201 via a bearing drive. A second transmission roller 208 is fixedly connected to the surface of the second rotating shaft 207. The second transmission roller 208 and the first transmission roller 205 are connected via a conveyor belt 206. The surface of the conveyor belt 206 is provided with honeycomb-shaped through holes. The position of the conveyor belt 206 corresponds to the position of the liquid accumulation tank 6. The conveyor belt 206 is set at a 30-degree angle between the two sets of support plates 201. A guide plate 7 is fixedly connected to the side of the support plate 201. The position of the guide plate 7 corresponds to the position of the conveyor belt 206. A scraper 212 is fixedly connected to the side of the support plate 201. The upper end of the scraper 212 overlaps the lower surface of the conveyor belt 206. A first sprocket 209 is fixedly connected to the surface of the first rotating shaft 204. A chain 211 overlaps the surface of the first sprocket 209. A second sprocket 210 is fixedly connected to the surface of the second rotating shaft 207. The second sprocket 210 and the first sprocket 209 are connected via a chain 211. By setting up the screening component 2, since the conveyor belt 206 is inclined at a 30-degree angle, the honeycomb-shaped through holes on its surface allow the water in the hazardous waste to quickly permeate to the liquid collection tank 6 below under the action of gravity, thus achieving solid-liquid separation. At the same time, the first drive roller 205 is made of permanent magnet material, which can adsorb ferrous metals in the crushed hazardous waste during the operation of the conveyor belt 206. When the conveyor belt 206 turns to the lower side with the drive roller, the scraper 212 scrapes the adsorbed metals down to the collection box 4, thus achieving the separation of metals from other hazardous wastes, improving resource recycling efficiency, and meeting the needs of the circular economy. In this embodiment, by setting up a crushing component 3, a screening component 2, and a liquid collection tank 6, the hazardous waste is crushed by the crushing component 3, and the screening, dehydration, and ferrous metal recovery of the crushed hazardous waste are completed simultaneously by the conveyor belt 206 of the screening component 2. This solves the problem of traditional equipment having a single function and requiring step-by-step operation, making the hazardous waste treatment process simpler and more convenient, thereby greatly improving the efficiency of hazardous waste pretreatment. There is a gap between the guide plate 7 and the conveyor belt 206 to allow the adsorbed magnetic material to pass through. The hazardous waste fragments are conveyed to the end of the conveyor belt 206 and, under the action of inertia, detach from the conveyor belt 206 and fall onto the surface of the guide plate 7 in a parabolic trajectory. The hazardous waste is discharged by the guidance of the guide plate 7. That is, the probability of hazardous waste fragments falling from the gap between the guide plate 7 and the conveyor belt 206 is very small. Even if a small amount of hazardous waste fragments falls during the actual screening process, it will not have a significant impact on the overall process.

[0018] Please see Figure 1 and Figure 4 The crushing component 3 is set on the upper end of the screening component 2. The crushing component 3 is used to crush hazardous waste. The crushing component 3 includes a shell 301, which is fixedly connected to the upper end of the support plate 201. A second fixed platform 302 is fixedly connected to the side of the shell 301. A second forward and reverse motor 303 is fixedly connected to the upper surface of the second fixed platform 302. A third rotating shaft 304 is fixedly connected to the other end of the output shaft of the second forward and reverse motor 303. The third rotating shaft 304 is connected to the surface of the shell 301 through a bearing drive. A first crushing roller 305 is fixedly connected to the surface of the third rotating shaft 304. A fourth rotating shaft 306 is connected to the inner wall of the shell 301 through a bearing drive. A second crushing roller 307 is fixedly connected to the surface of the fourth rotating shaft 306. The second crushing roller 307 matches the first crushing roller 305. A first gear 308 is fixedly connected to the surface of the third rotating shaft 304. A second gear 309 is fixedly connected to the surface of the fourth rotating shaft 306. The second gear 309 meshes with the first gear 308. In this embodiment, by setting the crushing component 3, the second forward and reverse motor 303 is started, which drives the third rotating shaft 304 to rotate. Through the meshing transmission of the first gear 308 and the second gear 309, the fourth rotating shaft 306 is driven to rotate synchronously in the opposite direction, so that the first crushing roller 305 and the second crushing roller 307 rotate in opposite directions, which can squeeze and shear the hazardous waste.

[0019] Please see Figure 1 , Figure 2 and Figure 3A slurry collection tank 6 is provided on the upper end of the base 1. The position of the slurry collection tank 6 corresponds to the position of the screening component 2. The slurry collection tank 6 is used to collect the filtered wastewater. A collection box 4 is attached to the upper surface of the base 1. A handle 5 is fixedly connected to the side of the collection box 4. There are two sets of handles 5, which are symmetrically arranged on both sides of the collection box 4. The position of the collection box 4 corresponds to the position of the scraper 212. A drain pipe 8 is fixedly connected to the side of the slurry collection tank 6. A valve 9 is provided on the surface of the drain pipe 8. When the valve 9 is opened, the sewage collected inside the slurry collection tank 6 can be discharged through the drain pipe 8.

[0020] The working principle and usage process of this utility model are as follows: First, the hazardous waste to be processed (hazardous waste) is put into the outer shell 301 of the crushing component 3. The second forward and reverse motor 303 is started, which drives the third rotating shaft 304 to rotate. Through the meshing transmission of the first gear 308 and the second gear 309, the fourth rotating shaft 306 is driven to rotate synchronously in the opposite direction, so that the first crushing roller 305 and the second crushing roller 307 rotate in opposite directions, squeezing and shearing the hazardous waste. The volume of the crushed hazardous waste is much larger than the through hole on the surface of the conveyor belt 206. Next, the crushed hazardous waste fragments fall through the bottom of the outer shell 301 onto the conveyor belt 206 of the screening component 2. The first forward and reverse motor 203 is started, and the motor drives the first rotating shaft 204 to rotate. Through the transmission of the first sprocket 209, chain 211 and second sprocket 210, the second rotating shaft 207 rotates synchronously, driving the first transmission roller 205 and the second transmission roller 208 to drive the conveyor belt 206 to run. During the inclined conveying process, the water contained in the hazardous waste fragments on the conveyor belt 206 drips through the honeycomb-shaped through holes into the liquid collection tank 6 below to achieve dehydration. The wastewater in the liquid collection tank 6 can be discharged and treated through the drain pipe 8. Meanwhile, when the first drive roller 205 is running on the conveyor belt 206, it will adsorb the ferrous metal in the hazardous waste fragments and move with the conveyor belt 206. Since the particles of the ferrous metal fragments are much larger than the through holes on the surface of the conveyor belt 206, the ferrous metal fragments can only be adsorbed on the surface of the conveyor belt 206 at the first drive roller 205. When the conveyor belt 206 runs to the lower side and comes into contact with the scraper 212, the scraper 212 scrapes the adsorbed metal fragments off the surface of the conveyor belt 206 and drops them into the collection box 4 to complete the recycling. After the final pretreatment is completed, the first forward and reverse motor 203 and the second forward and reverse motor 303 are turned off to stop the device from operating. The ferrous metal in the collection box 4 can be removed by the handle 5, and the wastewater in the liquid pool 6 can be discharged through the valve 9, thus completing one hazardous waste pretreatment process.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
