Description

Technical Field

[0001] This utility model belongs to the field of waste landfill technology, specifically relating to a safe landfill mechanism for tribasic lead sulfate waste. Background Technology

[0002] Tribasic lead sulfate is commonly used in the polyvinyl chloride (PVC) processing industry. Lead is the main hazardous component in its waste, exhibiting high toxicity, bioaccumulation, and non-degradability. Before landfilling, the waste must be pretreated, typically including crushing and screening to process it into suitable particle sizes for subsequent landfilling. After landfilling, additives need to be sprayed. The curing agent in the additive can chelate with heavy metal ions to form stable complexes, enhancing the curing effect.

[0003] Currently, after tribasic lead sulfate waste is landfilled, additives need to be sprayed manually. The manual operation is relatively slow, requiring personnel to move back and forth in the landfill area to spray, which makes the landfill operation unable to be carried out continuously and efficiently, delaying the overall landfill progress and thus reducing the overall operational efficiency of the landfill.

When the pre-treated lead sulfate waste particles fall, the valve on the second connecting pipe 7 is opened to start the water pump 6. The solution in the storage tank 4 is sprayed out through the first connecting pipe 5, the second connecting pipe 7, and the water outlet plate 8, and then sprayed out through the nozzle 9 to spray the waste falling into the landfill body 1. The solvent is a mixture of solidifying agent, adsorbent and water. The mixed spraying can play the role of solidification and adsorption at the same time, enhancing the fixation effect of lead in the waste.

[0023] The drive assembly includes a first motor 11, a first rotating shaft 12, a first pulley 15, a belt 16, a second pulley 17, and a second rotating shaft 18. The output end of the first motor 11 is fixedly connected to the first rotating shaft 12. The side surface of the first rotating shaft 12 is fixedly connected to the first pulley 15. The inner surface of the second pulley 17 is fixedly connected to the second rotating shaft 18. A flipping plate 13 and a flipping rod 14 are fixedly connected to the side surface of the first rotating shaft 12. When the first motor 11 is started, the output end of the first motor 11 rotates, driving the first rotating shaft 12, the flipping plate 13, and the flipping rod 14 to rotate, which can flip the material in the feeding box 3. A mixing rod is fixedly connected to the side surface of the second rotating shaft 18. 19. The rotation of the first rotating shaft 12 drives the first pulley 15 to rotate. Under the action of the belt 16, the second pulley 17, the second rotating shaft 18 and the mixing rod 19 rotate, which can stir the solution in the storage tank 4, making the solution in 1 more uniformly mixed, and thus allowing the solvent to be sprayed evenly. The front surface of the feeding box 3 is fixedly connected to the fixing frame 10, and the front surface of the fixing frame 10 is fixedly connected to the first motor 11, which increases the stability of the structural connection. The side surface of the second rotating shaft 18 is rotatably connected to the storage tank 4, and the side surface of the first rotating shaft 12 is rotatably connected to the feeding box 3.

[0024] The moving assembly includes a fixed rod 2, a second motor 27, a lead screw 28, and a slider 29.

The lower surface of the slider 29 is fixedly connected to the feeding box 3, and the side surface of the feeding box 3 is fixedly connected to the storage tank 4. When the second motor 27 is started, it drives the lead screw 28 to rotate. The lead screw 28 is threadedly connected to the slider 29, causing the slider 29 to slide in the groove inside the fixed rod 2, thereby moving the feeding box 3 and the storage tank 4. The position of the feeding box 3 can be adjusted according to the landfill progress. The feeding box 3 and the storage tank 4 have high flexibility of use. The lower surface of the fixed rod 2 is provided with a support column to support the fixed rod 2.

[0025] A cylinder 20 is fixedly connected to the lower surface of the feeding box 3, and a baffle 21 is fixedly connected to the output end of the cylinder 20. A discharge port 22 is provided inside the feeding box 3. The lower surface of the feeding box 3 is slidably connected to the baffle 21. Activating the cylinder 20 moves the baffle 21, causing the material inside the feeding box 3 to fall through the discharge port 22. Simultaneously, under the action of the drive assembly, the flipping plate 13, and the flipping rod 14, the material particles inside fall evenly. A feed hopper 23 is fixedly connected to the upper surface of the feeding box 3. Through the feed... The hopper 23 adds pretreated tribasic lead sulfate waste particles into the feeding box 3.

The protective boxes are not shown. At the same time, the first motor 11, the second motor 27, the water pump 6, and the cylinder 20 are all electrically connected to an external controller. The first motor 11, the second motor 27, the water pump 6, and the cylinder 20 are all electrically connected to the lithium battery inside the protective box on the right side of the feeding box 3.

[0026] The bottom inner wall of the landfill body 1 is provided with a concrete protective layer 24, the bottom inner wall of the concrete protective layer 24 is provided with a bentonite waterproof blanket layer 25, and the bottom inner wall of the bentonite waterproof blanket layer 25 is provided with a geomembrane layer 26. The geomembrane layer 26 is made of high molecular polymer and has extremely low permeability, which can effectively prevent harmful substances in leachate from seeping into the surrounding soil and groundwater. Bentonite is a natural mineral material that expands when it comes into contact with water. After absorbing water, the bentonite particles in the bentonite waterproof blanket layer 25 expand several times in volume, forming a dense gel-like substance that fills the tiny gaps and defects in the geomembrane layer 26, further enhancing the seepage prevention effect. The concrete protective layer 24 protects the geomembrane layer 26 and the bentonite waterproof blanket layer 25. The concrete protective layer 24, the bentonite waterproof blanket layer 25, and the geomembrane layer 26 form a structure that constitutes the internal seepage prevention layer of the landfill body. This structure can prevent leachate leakage, protect the soil and groundwater environment, and achieve the safe landfilling of tribasic lead sulfate waste.

[0027] The working principle of this utility model is as follows: During use, pretreated tribasic lead sulfate waste particles are added to the feeding box 3 through the feeding hopper 23. A mixture of curing agent, adsorbent, and water is added to the storage tank 4. The cylinder 20 is activated, moving the baffle 21 to open the opening below the discharge port 22. The first motor 11 is then activated, and its output rotates, driving the first rotating shaft 12, the flipping plate 13, and the flipping rod 14 to rotate. This flips the material in the feeding box 3, causing it to fall evenly. The waste particles in the feeding box 3 are agitated by the flipping plate 13. Under the action of the tipping rod 14, the material falls into the landfill body 1 through the discharge port 22. At the same time, the first rotating shaft 12 rotates, driving the first pulley 15 to rotate. Under the action of the belt 16, the second pulley 17, the second rotating shaft 18 and the mixing rod 19 rotate, which can agitate the solution in the storage tank 4. While the material is falling, the valve on the second connecting pipe 7 is opened to start the water pump 6. The solution in the storage tank 4 passes through the first connecting pipe 5, the second connecting pipe 7 and the water outlet plate 8 and is sprayed out through the nozzle 9 to spray the waste falling into the landfill body 1 with solvent.
