Description

Technical Field

[0001] The utility model relates to the technical field of hazardous waste treatment, in particular to a solid-liquid separation device for hazardous waste treatment. Background Art

[0002] The existing patent, a solid-liquid separation device for hazardous waste treatment (CN220989945U), includes a box body. An opening is provided on the side wall of the box body, and a screen is slidably connected inside the opening. Both sides of the screen penetrate through the box body through the opening respectively. With the above structure, after putting the hazardous waste containing waste liquid into the box body, the electric push rod drives the connecting frame to make a horizontal reciprocating motion, so that the connecting frame can drive the filter screen to move simultaneously. When the roller passes over the convex block, it will move longitudinally to make the screen shake longitudinally. And the shaking frequency of the screen is increased by the support component, so that the screen plays a role of vibrating screening, thereby achieving the effect of solid-liquid separation, and the solid waste is discharged through the opening under vibration.

[0003] The technical solution of this application can effectively improve the efficiency of solid-liquid separation, and can effectively prevent a large amount of liquid from following the solid waste to be discharged, thus effectively improving the effect of solid-liquid separation. However, it is very likely that toxic substances will volatilize in hazardous waste. The feeding, discharging and screening processes in this technical solution are all in an open environment, so there are risks. Summary of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figures 1-5 , a solid-liquid separation device for hazardous waste treatment, including a separation box 1, a separation hopper 2 is rotatably connected inside the separation box 1, a feed sleeve 3 is arranged at the top end of the separation box 1, one end of the feed sleeve 3 is provided with a feed inlet 4 and the other end is provided with a discharge outlet 5, and sealing plates 6 connected by sliding are arranged at both the feed inlet 4 and the discharge outlet 5. One end of the feed inlet 4 is provided with a pusher block 7, a telescopic sleeve 8 is arranged outside the feed sleeve 3, and the free end of the telescopic sleeve 8 is fixedly connected to the pusher block 7. A motor 9 is fixedly installed at the bottom end of the separation box 1, and the output end of the motor 9 is fixedly connected to the separation box 1. A magnetic filter plate 10 is fixedly installed inside the separation box 1, an electromagnetic column 11 is fixedly installed at the bottom end of the separation box 1, and a drainage control valve 17 is connected and penetrates through the side wall of the separation box 1.

[0023] A group of drainage ports 12 are opened at the bottom edge of the separation box 1, a drainage ring 13 covering the drainage ports 12 is fixedly installed at the outer end of the separation box 1, the drainage ring 13 is connected and penetrates through the separation box 1, and the drainage control valve 17 is connected and penetrates through the outer surface of the drainage ring 13. Through such a setting, solid-liquid separation can be realized after the separation hopper 2 rotates, the liquid can be discharged out in time, and then discharged through a unified larger discharge port.

[0024] Inside the separation hopper 2, a concentric spacer ring 18 is fixedly installed. Through holes 14 are formed in the inner wall of the spacer ring 18. A limit through slot 15 is formed in the middle of the separation hopper 2. The magnetic filter plate 10 is slidably connected inside the limit through slot 15. The part of the magnetic filter plate 10 located on the bearing part protrudes upward and is flush with the upper surface of the spacer ring 18. Through such a setting, the separation hopper 2 can be restricted into multiple cavities, and solid-liquid separation can be carried out in each cavity. The liquid can drain downward through the through holes 14, thereby increasing the efficiency of solid-liquid separation.

[0025] The feed inlet 4 is located above the feed sleeve 3. The width of the push block 7 is greater than the width of the feed inlet 4, and the length of the push block 7 is the same as the width of the feed sleeve 3. Through such a setting, the push block 7 can be used to put the input hazardous waste into the device, and after the input, the push block 7 can cover the feed inlet 4 to reduce the volatilization of harmful substances from the feed inlet 4.

[0026] Support half-rings 16 are fixedly installed on the inner bottom wall of the separation box 1 and at the bottom end of the separation hopper 2. There are gaps between adjacent support half-rings 16, and the upper and lower support half-rings 16 are arranged in a staggered manner.

The upper surface of the separation box 1 and the upper surface of the spacer ring 18 are flush with the inner bottom wall of the feed sleeve 3. Through such a setting, after the magnetic filter plate 10 rises, it can remain flush with the inner bottom wall of the feed sleeve 3, and the separated solids can be completely discharged from the device by the push block 7.

[0028] During use, open the sealing plate 6 of the feed inlet 4 of the solid-liquid waste and push it into the inside of the separation hopper 2 from the feed inlet 4 using the push block 7. The separation hopper 2 rotates slowly to evenly distribute the processed material. The separation hopper 2 rotates at a high speed, and under the action of centrifugal force, the liquid is discharged through the through holes 14 to achieve solid-liquid separation. After the separation is completed, open the sealing plate 6 at the discharge port 5 end and energize the electromagnetic column 11, so that the magnetic filter plate 10 can be pushed upward, causing the solid waste to rise and be pushed out by the push block 7. After the push block 7 resets, increase the current magnitude to make the magnetic filter plate 10 rise periodically until the solid waste is completely discharged. The whole process is in a closed state to avoid the volatilization of harmful substances.
