Description

Technical Field

[0001] This utility model belongs to the field of waste electronic product recycling technology, specifically a leaching device for recycling metal components of waste electronic products. Background Technology

[0002] With the rapid development of the electric vehicle industry, its ownership continues to rise, resulting in an increasing number of scrapped electric vehicles. These scrapped electric vehicles contain a large number of waste electronic products, such as lithium-ion power batteries. These waste electronic products contain abundant valuable metals, such as lithium, cobalt, nickel, and copper. If these metals can be effectively recycled, it will not only help alleviate the problem of resource shortage, but also reduce potential harm to the environment. The metals in the waste electronic products can be extracted through acid leaching.

[0003] In existing leaching devices for recycling metal components of waste electronic products, the placement frame and the leaching device are usually fixed together with bolts during acid leaching, which is inconvenient to disassemble and assemble. After each acid leaching, the waste electronic product metal components in the placement frame need to be completely cleaned before acid leaching can be carried out again, which can easily affect the recycling efficiency of waste electronic product metal components. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a leaching device for recycling metal components of waste electronic products. It solves the problem that in existing leaching devices for recycling metal components of waste electronic products, the placement frame and the leaching device are generally fixed together with bolts during acid leaching, which makes it inconvenient to disassemble the placement frame. After each acid leaching, the waste electronic product metal components in the placement frame need to be completely cleaned before the waste electronic product metal components can be acid leached again, which easily affects the recycling efficiency of waste electronic product metal components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leaching device for recycling metal components of waste electronic products, comprising a processing tank, electric lifting rods symmetrically fixedly installed on both sides of the processing tank, a fixing frame fixedly installed between the telescopic ends of the top of the four electric lifting rods, mounting grooves provided at the four corners of the fixing frame, a limiting plate slidably installed at one end inside the mounting groove, a moving rod fixedly installed on one side of the limiting plate, and a fixing spring sleeved on the surface of the moving rod inside the mounting groove, two moving rods on the same side of the fixing frame extending through the mounting groove to the top of the fixing frame and fixedly installed with fixing clips, and a grid placement frame snapped into the inside of the fixing frame.

[0006] As a further embodiment of this utility model: a drain trough is provided at the center of the bottom of the processing box, and a drain valve is fixedly installed on the bottom of one side of the processing box, and the drain valve is connected to the drain trough.

[0007] As a further embodiment of this utility model: a reciprocating screw is rotatably mounted at the bottom center position on both sides of the inner wall of the processing box via bearings, a rotating motor is fixedly mounted on one side of the processing box, and bevel gears are fixedly connected to the output end of the rotating motor and the end of the reciprocating screw located on the outside of the processing box, and the two bevel gears mesh with each other.

[0008] As a further embodiment of this utility model: the bottom of the processing box is symmetrically and fixedly installed on both sides of the reciprocating screw, and a moving block is slidably connected through the surface of the limiting slide rod.

[0009] As a further embodiment of this utility model: the reciprocating screw is threadedly connected to a movable seat on the surface inside the processing box, and the movable seat corresponds to the position of the movable block.

[0010] As a further embodiment of this utility model: stirring plates are fixedly installed on both sides of the movable seat, and the end of the stirring plate away from the movable seat is fixedly connected to the movable block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This leaching device for recycling metal components from waste electronic products uses a fixed spring, a fixed locking strip, and a grid placement frame. Pushing the fixed locking strip to both sides causes the moving rod to slide inside the mounting groove, which in turn causes the limiting plate to compress the fixed spring inside the mounting groove, deforming it and placing the grid placement frame inside the fixing frame. After the top of the grid placement frame is engaged with the top of the fixing frame, the fixed locking strip is released, and the limiting plate is lifted by the rebound of the fixed spring. This pushes the moving rod to cause the fixed locking strip to slide on the top of the fixing frame until the fixed locking strip covers the top of the grid placement frame, thus securing the grid placement frame inside the fixing frame and facilitating the disassembly and replacement of the grid placement frame.

[0013] This leaching device for recycling metal components from waste electronic products uses a reciprocating screw, a rotating motor, a moving base, and a stirring plate. After pouring an appropriate amount of acid leaching solution into the treatment tank, the electric lifting rod is extended and retracted to immerse the grid placement frame in the acid leaching solution. Then, the rotating motor is started to control the reciprocating screw to rotate, causing the moving base to move back and forth on the surface of the reciprocating screw. This causes the stirring plate to agitate the acid leaching solution, which in turn impacts the accumulated metal components from waste electronic products inside the grid placement frame, thereby improving the efficiency of recycling and leaching metal components from waste electronic products.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a leaching device for recycling metal components of waste electronic products, including a processing tank 1, electric lifting rods 2 are symmetrically fixedly installed on both sides of the processing tank 1, and a fixing frame 3 is fixedly installed between the telescopic ends of the top of the four electric lifting rods 2. A grid placement frame 9 is snapped into the inside of the fixing frame 3. Because of the grid placement frame 9, after the grid placement frame 9 is placed into the fixing frame 3, it is snapped and fixed. The metal components of waste electronic products are poured into the grid placement frame 9, and the electric lifting rods 2 are controlled to extend and retract to drive the grid placement frame 9 to be immersed in the processing tank 1, so that the metal components of waste electronic products come into contact with the acid leaching solution and react.

[0020] The four corners of the mounting frame 3 are provided with mounting grooves 4. A limiting plate 5 is slidably installed at one end of the mounting groove 4. A moving rod 6 is fixedly installed on one side of the limiting plate 5, and a fixing spring 7 is sleeved on the surface of the moving rod 6 inside the mounting groove 4. Two moving rods 6 on the same side of the mounting frame 3 pass through the mounting groove 4 and extend to the top of the mounting frame 3, where a fixing clip 8 is fixedly installed. With the fixing spring 7, the fixing clip 8 is pushed to move on the top of the mounting frame 3, causing the moving rod 6 and the limiting plate 5 to slide inside the mounting groove 4, compressing the fixing spring 7 to deform inside the mounting groove 4 until the grid placement frame 9 is inserted into the mounting frame 3. After the fixing clip 8 is released, the limiting plate 5 is lifted by the rebound action of the fixing spring 7, causing the fixing clip 8 to slide on the top of the mounting frame 3, so that the fixing clip 8 presses and fixes the grid placement frame 9 inside the mounting frame 3.

[0021] A drain trough 10 is provided at the center of the bottom of the treatment box 1. A drain valve 11 is fixedly installed on the bottom of one side of the treatment box 1 and is connected to the drain trough 10. Because of the drain valve 11, opening the drain valve 11 allows the acid leaching solution inside the treatment box 1 to flow from the drain trough 10 to the drain valve 11 for discharge, thus replacing the acid leaching solution.

[0022] A reciprocating screw 12 is rotatably mounted on the bottom center of both sides of the inner wall of the processing box 1 via bearings. A rotary motor 13 is fixedly mounted on one side of the processing box 1. The output end of the rotary motor 13 and the end of the reciprocating screw 12 located on the outside of the processing box 1 are respectively fixedly connected to bevel gears 14, and the two bevel gears 14 mesh with each other. By providing the reciprocating screw 12, the rotary motor 13 is started and the reciprocating screw 12 is rotated through the transmission of the bevel gears 14, so that the moving seat 15 moves back and forth on the surface of the reciprocating screw 12.

[0023] Limiting slide rods 16 are symmetrically fixedly installed on both sides of the reciprocating screw 12 at the bottom of the processing box 1. A moving block 17 is slidably connected through the surface of the limiting slide rod 16. A moving seat 15 is threadedly connected through the surface of the reciprocating screw 12 inside the processing box 1, and the moving seat 15 corresponds to the position of the moving block 17. Because of the limiting slide rod 16, the moving seat 15 rotates with the reciprocating screw 12, causing the moving block 17 to move back and forth on the surface of the limiting slide rod 16, thus limiting the moving block 17 and ensuring that the moving block 17 will not tilt or deflect when sliding on the surface of the limiting slide rod 16.

[0024] A stirring plate 18 is fixedly installed on both sides of the movable base 15, and the end of the stirring plate 18 away from the movable base 15 is fixedly connected to the movable block 17. With the stirring plate 18, the movable base 15 drives the stirring plate 18 to move back and forth inside the processing tank 1, stirring the acid leaching solution to flow inside the processing tank 1, so that the acid leaching solution impacts the metal components of waste electronic products, thereby improving the efficiency of recycling and processing of metal components of waste electronic products.

[0025] The working principle of this utility model is as follows:

[0026] Close the drain valve 11 and pour an appropriate amount of acid leaching solution into the treatment tank 1. Push the fixing strip 8 to slide on top of the fixing frame 3, causing the moving rod 6 and the limiting plate 5 to slide inside the mounting groove 4, compressing the fixing spring 7 to deform, and placing the grid placement frame 9 into the fixing frame 3. Release the fixing strip 8, and under the rebound action of the fixing spring 7, push the limiting plate 5 towards one end inside the mounting groove 4. Use the moving rod 6 to pull the fixing strip 8 to tightly cover the top of the grid placement frame 9, clamping and fixing the grid placement frame 9 inside the fixing frame 3, and then place the grid placement frame into the mounting groove 4. Pour an appropriate amount of waste electronic product metal components into the frame 9. Control the electric lifting rod 2 to retract, driving the fixing frame 3 and the grid placement frame 9 to move down until the grid placement frame 9 is immersed in the acid leaching solution inside the treatment tank 1. Start the rotating motor 13 to control the reciprocating screw 12 to rotate, causing the moving seat 15 to drive the stirring plate 18 to move back and forth inside the treatment tank 1, stirring the acid leaching solution to leach the waste electronic product metal components inside the grid placement frame 9, so that the metal elements in the waste electronic product metal components react with the acid leaching solution and precipitate out.
