Hazardous wastes will have a serious impact on the ecological environment and even human health. Therefore, hazardous wastes must be centrally treated. Hazardous waste landfill is a disposal facility that centrally landfills hazardous wastes. It accepts many types of hazardous wastes from a wide range of sources. Moreover, most hazardous wastes cannot meet the requirements of direct landfill due to excessive hazardous components. Therefore, stabilization treatment is required before landfill disposal to reduce its hazard and meet the waste landfill standards.

[0003] At present, hazardous waste solidification treatment devices all collect hazardous wastes together and then use solidifying agents to directly treat them or process them after manual screening. Due to the wide variety of hazardous wastes and their different shapes and sizes, the shapes after solidification are also uneven and the stability is not high. In addition, all hazardous wastes are solidified by the same solidification method, and the solidification effect is not good. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] Reference Figure 1-Figure 4 A hazardous landfill waste stabilization disposal device comprises a base 1 and a spring sheet 4, wherein four symmetrical first fixed blocks 11 are fixedly connected to the side walls along the length direction of the base 1, and a support leg 12 is fixedly connected to the lower surface of the base 1, and a first screening plate 2 and a second screening plate 3 are arranged above the base 1, wherein the length of the first screening plate 2 is greater than the length of the base 1, the length of the first screening plate 2 is less than the length of the second screening plate 3, the diameter of the sieve holes on the first screening plate 2 is less than the diameter of the sieve holes on the second screening plate 3, the first screening plate 2 and the second screening plate 3 can screen the hazardous waste into three types: large hazardous waste, small hazardous waste and liquid hazardous waste, and the upper surfaces of the base 1, the first screening plate 2 and the second screening plate 3 are all provided with inclined chutes, and the inclination angle of the chutes is 20°-30°. At this angle, the speed at which the hazardous waste slides down is moderate, which is conducive to better screening.

[0022] The first screening plate 2 is located between the base 1 and the second screening plate 3. Four symmetrical second fixing blocks 21 and four symmetrical third fixing blocks 22 are fixedly connected to the side walls of the first screening plate 2 along the length direction. Four symmetrical fourth fixing blocks 31 are fixedly connected to the side walls of the second screening plate 3 along the length direction. The first fixing block 11 and the second fixing block 21 are aligned in the vertical direction, and the third fixing block 22 and the fourth fixing block 31 are aligned in the vertical direction. The first fixing block 11 and the second fixing block 21 are fixedly connected by a spring sheet 4, and the third fixing block 22 and the fourth fixing block 31 are fixedly connected by a spring sheet 4. The first screening plate 2 and the second screening plate 3 are connected by the spring sheet 4, so that the first screening plate 2 and the second screening plate 3 vibrate synchronously after being subjected to force to screen hazardous wastes, thereby saving the cost of manual screening and avoiding adverse effects of hazardous wastes on the bodies of screening workers.

[0023] A dual-axis motor 5 is fixedly connected to one end of the first screening plate 2, and cams 51 are fixedly connected to the two output shafts of the dual-axis motor 5. A connecting rod 6 is rotatably connected to the cam 51. A rotating shaft 7 is rotatably connected to the upper surface of the second screening plate 3, and the connecting rod 6 is rotatably connected to the rotating shaft 7 at one end away from the dual-axis motor 5. Two symmetrical ear seats 32 are arranged on the upper surface of the second screening plate 3, and the rotating shaft 7 is rotatably connected to the ear seats 32. A first solidification pool 8, a second solidification pool 9 and a third solidification pool 10 are respectively arranged below the ends of the base, the first screening plate 2 and the second screening plate 3 away from the dual-axis motor 5. The solidification method of the first solidification pool 8 is silicone solidification, the solidification method of the second solidification pool 9 is asphalt solidification, and the solidification method of the third solidification pool 10 is plastic solidification. The screened hazardous wastes slide into the corresponding solidification treatment pools respectively. Hazardous wastes in different forms adopt corresponding appropriate solidification methods, which have better solidification effects and higher stability after solidification.

[0024] The functional principle of the present invention can be explained through the following operation mode: when performing the solidification treatment, the dual-axis motor 5 is turned on, and the dual-axis motor 5 drives the cam 51 to rotate. Under the action of the connecting rod 6 and the spring sheet 4, the first screening plate 2 and the second screening plate 3 vibrate synchronously, and the hazardous waste is placed on the second screening plate 3. Small pieces of hazardous waste and liquid hazardous waste fall onto the first screening plate 2 under the vibration action of the second screening plate 3, and the liquid hazardous waste falls onto the base 1 under the vibration action of the first screening plate 2. Finally, the liquid hazardous waste, small pieces of hazardous waste and large pieces of hazardous waste slide along the inclined chutes into the first solidification pool 8, the second solidification pool 9 and the third solidification pool 10 respectively, and are solidified in different ways suitable for their respective forms. The present invention can screen the hazardous waste without manual operation, which reduces the labor cost and avoids the adverse effects of hazardous waste on workers. The present invention adopts corresponding appropriate solidification methods for hazardous wastes in different forms, and the solidification effect is better and the stability after solidification is higher.
