Description

Technical Field

[0001] The present invention belongs to the technical field of battery recycling, and specifically refers to a device for harmless treatment of battery recycling. Background Art

[0002] Waste batteries contain various harmful substances, such as heavy metals (mercury, cadmium, lead, etc.) and organic solvents in the electrolyte. If not properly treated, they will cause serious harm to the environment and human health. At the same time, the metal resources (such as lithium, cobalt, nickel, etc.) and renewable resources such as plastics in waste batteries also have high recycling value. Therefore, the harmless crushing treatment of battery recycling is of great significance for reducing environmental pollution, saving resources and promoting sustainable development.

[0003] Currently, the existing devices for harmless treatment of battery recycling have the following problems: When the existing device for harmless treatment of battery recycling crushes the battery in an inert environment, it cannot ensure the purity of the inert gas in the inert environment, resulting in the battery material after crushing being prone to oxidation reaction, thereby reducing the recycling quality of the battery material. Therefore, it cannot meet the current usage requirements of the device for harmless treatment of battery recycling. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present solution provides a device for harmless treatment of battery recycling that can pre-release the gas remaining inside the battery, ensure that the exposed battery material after crushing does not undergo an oxidation reaction, and thereby improve the recycling quality of the battery material.

[0005] The technical solution adopted in this solution is as follows: A device for harmless treatment of battery recycling proposed in this solution includes a nitrogen gas tank, a filling cylinder, a crushing cylinder, a side-mounted crushing mechanism, and an inserted gas release mechanism. The filling cylinder is provided on the upper wall of the nitrogen gas tank, the crushing cylinder is provided on the bottom wall of the filling cylinder, the crushing cylinder is open at the upper end, the side-mounted crushing mechanism is provided on the side wall of the filling cylinder, the inserted gas release mechanism is provided on the upper wall of the filling cylinder. The side-mounted crushing mechanism includes a loading mechanism, a pushing mechanism, a limiting mechanism, and a crushing mechanism. The loading mechanism is provided on the side wall of the filling cylinder, the pushing mechanism is provided on the loading mechanism, the limiting mechanism is provided at one end of the loading mechanism away from the pushing mechanism, and the crushing mechanism is provided on the crushing cylinder. The inserted gas release mechanism includes a cooling mechanism, a drilling mechanism, and a gas supply mechanism. The cooling mechanism is provided on the upper wall of the filling cylinder, the drilling mechanism is provided on the side wall of the cooling mechanism, and the gas supply mechanism is provided inside the nitrogen gas tank.

[0006] As a further optimization of the solution in this case, the loading mechanism includes a loading box, a sliding box, a locking frame, locking bolts and anti-slip bolts. Multiple groups of the loading boxes are arranged through between the filling cylinder and the crushing cylinder. The loading box is arranged in a through manner. The sliding box is slidably arranged inside the loading box. The sliding box is arranged with openings at both ends. The locking frame is arranged on the side of the sliding box away from the crushing cylinder. The locking bolts are symmetrically arranged at both ends of the locking frame. The end of the locking bolt away from the locking frame penetrates through the side wall of the loading box. The locking bolt is threadedly connected to the loading box. The anti-slip bolts are arranged in groups of two and penetrate through both sides of the loading box. The anti-slip bolts are threadedly connected to the loading box; the pushing mechanism includes a pushing magnetic plate, a pushing electromagnet and a pushing spring. The pushing magnetic plate is slidably arranged at one end of the sliding box close to the locking frame. The pushing electromagnet penetrates through the inner wall of the sliding box close to the pushing magnetic plate. The pushing spring is arranged between the pushing magnetic plate and the inner wall of the sliding box; the limiting mechanism includes a limiting groove, a limiting spring and a limiting wedge block. The limiting grooves are symmetrically arranged on the inner wall of the sliding box away from the locking frame. The limiting groove is arranged with an opening at one end. The limiting wedge block is slidably arranged inside the limiting groove. The limiting spring is arranged between the limiting groove and the limiting wedge block; the crushing mechanism includes a crushing motor, a crushing shaft and crushing cutters. The crushing motor is arranged on the upper wall of the crushing cylinder. The crushing shaft penetrates through the crushing cylinder and is arranged at the power end of the crushing motor. Multiple groups of the crushing cutters are arranged at the end of the crushing shaft away from the crushing motor.

[0007] During use, rotate the locking bolt. The locking bolt screws out from the side wall of the loading box. Pull the locking frame. The locking frame drives the sliding box to slide out along the inner wall of the loading box. Put the battery to be crushed into it through the upper opening of the sliding box. The batteries are placed flat and stacked inside the sliding box. The limiting spring is in an extended state. The distance between the limiting wedge blocks is the minimum value to limit the batteries inside the sliding box. Push the locking frame close to the side wall of the loading box and screw the locking bolt into the loading box. The sliding box is fixed inside the loading box. The pushing electromagnet is energized to generate magnetism. The pushing electromagnet and the pushing magnetic plate are arranged with the same poles. The pushing electromagnet is fixed on the inner wall of the sliding box and pushes the pushing magnetic plate through repulsion. The pushing magnetic plate uses the deformation of the pushing spring to push the batteries inside the sliding box into the crushing cylinder. Since the contact surface between the limiting wedge block and the battery is inclined, after the battery contacts the limiting wedge block, the limiting wedge block retracts into the limiting groove by using the deformation of the limiting spring. At this time, the distance between the limiting wedge blocks is the maximum value, which is convenient for the batteries inside the sliding box to enter the crushing cylinder. The crushing cutters are located between adjacent sliding boxes. Rotate the locking bolt. The locking bolt screws out of the loading box. Pull out the sliding box from the inside of the crushing cylinder through the locking frame. The crushing cutters cannot hit the sliding box during rotation. Since the side of the sliding box away from the crushing cylinder is closed and the inside of the crushing cylinder is in a sealed state, the crushing motor drives the crushing shaft to rotate through the power end. The crushing shaft drives the crushing cutters to crush the batteries inside the crushing cylinder.

[0008] Preferably, the cooling mechanism includes a cooling box, a thermoelectric cooler, and a cold air outlet. The cooling box is arranged on the upper wall of the packing cylinder. The thermoelectric cooler penetrates through the inner wall of the top of the cooling box. Multiple groups of cold air outlets are arranged on the side wall of the cooling box. The drilling mechanism includes drilling copper rods, a pressing plate, a drilling spring, and a sealing ring. Multiple groups of drilling copper rods penetrate through the packing cylinder and the crushing cylinder and are arranged on the side wall of one end of the cooling box close to the cold air outlet. The pressing plate is arranged on the upper wall of the drilling copper rod. The drilling spring is arranged between the pressing plate on the outer side of the drilling copper rod and the cooling box. The sealing ring is arranged on the upper wall of the packing cylinder on the outer side of the drilling copper rod, and the inner diameter of the sealing ring is smaller than the outer diameter of the drilling copper rod. The air supply mechanism includes an air pump, an intercepting net, a nitrogen sensor, and an exhaust valve. The air pump is arranged on the upper wall of the nitrogen gas tank. The exhaust end of the air pump is communicated with the crushing cylinder. The intercepting net penetrates through the inner wall of the bottom of the crushing cylinder. The exhaust valve is communicated and arranged on the upper wall of the packing cylinder. The nitrogen sensor is arranged on the upper wall of the packing cylinder, and the detection end of the nitrogen sensor penetrates through the packing cylinder and is arranged inside.

[0009] During use, in the initial state, the drilling spring is in an extended state. The tip of the drilling copper rod is located on the upper wall of the crushing cylinder. The thermoelectric cooler cools the air inside the cooling box through the cooling end. The cold air inside the cooling box cools the drilling copper rod through the cold air outlet. The operator presses the drilling copper rod through the pressing plate. The drilling copper rod penetrates through the upper wall of the crushing cylinder and enters the sliding box by using the deformation of the drilling spring. The drilling copper rod punctures the battery inside the sliding box. Then, the drilling copper rod is rotated. The drilling copper rod drives the battery to deflect. The drilling copper rod is pulled out of the battery. The battery is blocked by the upper wall of the sliding box and remains inside it. The drilling copper rod resets to the upper wall of the crushing cylinder and is placed there. The air pump extracts the nitrogen gas inside the nitrogen gas tank through the suction end. The nitrogen gas enters the crushing cylinder through the intercepting net. The exhaust valve is opened. The crushing cylinder is communicated with the outside through the exhaust valve. The nitrogen gas entering the crushing cylinder gradually squeezes out the air inside it. The air inside the crushing cylinder is discharged into the packing cylinder through the through-hole of the drilling copper rod. The nitrogen sensor detects the gas discharged from the inside of the crushing cylinder through the detection end. When the purity of the nitrogen gas reaches the user's requirement, the exhaust valve is closed so that the nitrogen gas cannot flow out, and the battery is crushed in a sealed inert environment.

[0010] Specifically, a controller is arranged on the side wall of the nitrogen gas tank.

[0011] Among them, the controller is electrically connected to the pushing electromagnet, the crushing motor, the thermoelectric cooler, and the nitrogen sensor respectively.

[0012] Preferably, the model of the nitrogen sensor is SEN-EDL-2-N2.

[0013] The beneficial effects obtained by adopting the above structure in this solution are as follows: Compared with the prior art, the present solution combines a puncture exhaust structure with a cryogenic intervention structure. Through the side-mounted crushing mechanism and the inserted air release mechanism provided, with the combined use of the loading mechanism, the material pushing mechanism, the limiting mechanism, the crushing mechanism, the cooling mechanism, the drilling mechanism and the air supply mechanism, it is ensured that the battery is always in an anaerobic environment during the crushing process, avoiding the occurrence of oxidation reactions of the internal materials of the battery during the crushing process, ensuring the recycling quality of the battery materials. By pre-punching the battery, excessive gases generated inside the battery due to overcharging, over-discharging, high-temperature environment or improper use can be released, preventing the gases inside the battery from flowing into the inert environment after crushing, and improving the stability of the inert environment during the battery crushing process to a certain extent. Nitrogen enters the inside of the crushing cylinder through the interception net. The exhaust valve is opened, and the crushing cylinder is communicated with the outside through the exhaust valve. The nitrogen entering the inside of the crushing cylinder gradually squeezes out the air inside it. The air inside the crushing cylinder is discharged into the filling cylinder through the through-hole of the drilling copper rod. The nitrogen sensor detects the gas discharged from the inside of the crushing cylinder through the detection end. When the purity of nitrogen reaches the user's requirements, the exhaust valve is closed to prevent the nitrogen from flowing out, and the battery is crushed under a sealed inert environment.

[0025] During specific use, in the initial state, the pushing spring 13 is in a compressed state, the limiting spring 16 is in an extended state, and the drilling spring 30 is in an extended state. Manually rotate the locking bolt 9, and the locking bolt 9 is screwed out from the side wall of the loading box 6. Pull the locking frame 8, and the locking frame 8 drives the sliding box 7 to slide out along the inner wall of the loading box 6. Place the battery to be crushed into it through the upper opening of the sliding box 7. The battery is placed flat and stacked inside the sliding box 7.

The operator presses the drilling copper rod 28 through the pressing rod plate 29. The drilling copper rod 28 penetrates the upper wall of the crushing cylinder 3 into the sliding box 7 by the deformation of the drilling spring 30. The drilling copper rod 28 pierces the battery inside the sliding box 7. Then, the drilling copper rod 28 is rotated, and the drilling copper rod 28 drives the battery to deflect. The drilling copper rod 28 is pulled out of the battery. The battery is blocked by the upper wall of the sliding box 7 and remains inside it.
