[0002] Hazardous solid waste refers to solid waste that is listed in the National Hazardous Waste List or identified as having hazardous characteristics according to the national hazardous waste identification standards and methods. When treating hazardous solid waste, it is necessary to use a crushing device to crush it, and then process it through subsequent processing.

[0003] A search revealed that Chinese patent application CN202320536086.4 discloses a pulverizing device for treating hazardous solid waste, comprising a pulverizing box, a feed inlet fixedly located at the top of the pulverizing box, a pair of rotating rods rotatably mounted above the pulverizing box, grinding rollers fixedly mounted on the rotating rods, and a plurality of first grinding teeth fixedly mounted circumferentially around the grinding rollers, the first grinding teeth on the two grinding rollers meshing with each other, gears fixedly mounted at the rear ends of the rotating rods, the two gears meshing with each other, guide plates fixedly mounted on the left and right sides of the grinding rollers inside the pulverizing box, a grinding disc rotatably connected to the pulverizing box below the guide plates, a conical head fixedly mounted on the top of the grinding disc, second grinding teeth fixedly mounted circumferentially around the grinding disc, and a hollow column fixedly mounted at the bottom of the pulverizing box, with third grinding teeth fixedly mounted circumferentially inside the hollow column.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] like Figure 1 - Figure 4As shown, this utility model provides a technical solution: a crushing device for treating hazardous solid waste, including a crushing box 1, a control box 11 fixedly connected to one side of the crushing box 1, and a feed inlet 12 fixedly connected to the middle of the upper side of the crushing box 1. A sealing cover 13 is rotatably connected to the upper end of the feed inlet 12, and a first discharge port 14 is rotatably connected to the lower end of the side of the crushing box 1 near the control box 11. A housing 15 is fixedly connected to the end of the crushing box 1 near the control box 11, and a bracket 16 is inserted into the inner side of the end of the housing 15 away from the crushing box 1. The end of the bracket 16 near the crushing box 1 is fixedly connected to the crushing box 1, and a motor 17 is fixedly connected to the upper end of the bracket 16. The output shaft of the motor 17 is provided with a transmission gear 18 through the processing assembly. The transmission gear 18 is rotatably connected to the crushing box 1 at one end, and a crushing roller 19 is fixedly connected to the other end of the transmission gear 18 that is away from the motor 17 through the crushing box 1. The crushing roller 19 is rotatably connected to the other end of the crushing box 1 at the other end. The processing component includes a first gear 21 fixedly connected to the outside of the output shaft of the motor 17. A second gear 22 is meshed at one end of the first gear 21. One end of the second gear 22 is rotatably connected to the outer casing 15. A toothed belt 23 is meshed on the outer side of one end of the second gear 22. The processing component can extract hazardous solid waste powder from the crushing device and then process the extracted powder to reduce the harm caused by hazardous solid waste powder to workers.

[0027] like Figure 2 As shown, a pipe 24 is provided on the outer side of the upper end of the toothed belt 23, and the end of the pipe 24 near the crushing box 1 is fixedly connected to the hood 25 through the crushing box 1. Gas and powder are transported through the hood 25 and the pipe 24.

[0028] like Figure 2 As shown, a flange 26 is rotatably connected to the inner side of the pipe 24 near the toothed belt 23, and the upper end of the toothed belt 23 is sleeved on the outer side of the flange 26. A fixing plate 27 is fixedly connected to the inner side of the flange 26, and a fan 28 is fixedly connected to the middle of the fixing plate 27. The air and powder inside the crushing box 1 are extracted by the rotation of the flange 26, the fixing plate 27 and the fan 28.

[0029] like Figure 1 As shown, a collection box 29 is fixedly connected to the end of the pipe 24 away from the hood 25, and a second discharge port 210 is rotatably connected to the lower end of the collection box 29. Hazardous powder is collected through the collection box 29, and the hazardous powder inside the collection box 29 can be cleaned through the second discharge port 210 later.

[0030] like Figure 2 and Figure 4As shown, an adsorber 211 is fixedly connected to the inner side of the upper end of the collection box 29, and an exhaust port 212 is fixedly connected to the upper end of the adsorber 211. The upper end of the exhaust port 212 is set through the collection box 29, and an air inlet 213 is fixedly connected to the outer side of the upper end of the adsorber 211. The harmful gas entering is filtered by the adsorber 211 and then discharged through the exhaust port 212.

[0031] It should be noted that the model of the 211 adsorber is the 3flex fully automatic physical adsorption instrument. It uses the porous structure and huge specific surface area of ​​adsorbents such as activated carbon and molecular sieves to adsorb harmful gas molecules on their surface, thereby achieving gas purification.

[0032] like Figure 4 As shown, a filter screen 214 is attached to the side of the air inlet 213 away from the adsorber 211, and an electric telescopic rod 215 is fixedly connected to the upper side of the collection box 29 near the filter screen 214. The lower end of the electric telescopic rod 215 passes through the collection box 29 and is fixedly connected to a connecting plate 216. A brush 217 is fixedly connected to the lower end of the connecting plate 216. The end of the brush 217 away from the connecting plate 216 is attached to the filter screen 214. The operation of the electric telescopic rod 215 drives the connecting plate 216 and the brush 217 to move back and forth, thereby using the brush 217 to clean the powder attached to the surface of the filter screen 214.

[0033] Working principle: When processing hazardous solid waste, the control box 11 first controls the operation of motor 17, adsorber 211, and electric telescopic rod 215. After motor 17 operates, its output shaft drives transmission gear 18 to rotate, which in turn drives crushing roller 19 to rotate. The output shaft of motor 17 then drives first gear 21 to rotate. First gear 21, after rotating, meshes with second gear 22, driving second gear 22 to rotate. Second gear 22, after rotating, meshes with toothed belt 23, driving toothed belt 23 to rotate. Toothed belt 23, after rotating, meshes with flange 26, driving flange 26, fixing plate 27, and fan 28 to rotate. The rotation of fan 28 draws air from inside the crushing chamber 1. Hazardous solid waste is then added to the crushing chamber 1 through feed inlet 12. At this time, the crushing roller... 19. Hazardous solid waste is crushed. The dust generated by crushing is drawn by the airflow generated by the fan 28. The drawn dust enters the pipe 24 through the hood 25 and then enters the collection box 29 for collection. The dust in the gas is filtered by the filter screen 214. Then the airflow enters the adsorber 211 through the air inlet 213. After being filtered by the adsorber 211, it is discharged through the exhaust port 212. The filtered dust falls into the inner side of the lower end of the collection box 29 for collection. When the electric telescopic rod 215 is turned, the output shaft drives the connecting plate 216 and the brush 217 to move back and forth. The reciprocating movement of the brush 217 cleans the dust attached to the surface of the filter screen 214. Later, the dust collected inside the collection box 29 can be cleaned by opening the second discharge port 210.

[0034] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
