[0002] Used batteries contain a variety of hazardous substances, such as heavy metals (mercury, cadmium, and lead) and organic solvents in the electrolyte. Improper handling can pose serious risks to the environment and human health. At the same time, metal resources (such as lithium, cobalt, and nickel) and renewable resources like plastics contained in used batteries also have high recycling value. Therefore, harmless battery recycling and shredding are crucial for reducing environmental pollution, conserving resources, and promoting sustainable development.

[0003] The existing battery recycling and harmless treatment devices have the following problems:

[0004] When existing battery recycling and harmless treatment equipment crushes batteries in an inert environment, it is unable to ensure the purity of the inert gas in the inert environment, resulting in the crushed battery materials being easily oxidized, thereby reducing the recycling quality of the battery materials. Therefore, it cannot meet the existing demand for the use of battery recycling and harmless treatment equipment. Summary of the Invention

[0006] The technical solution adopted in this scheme is as follows: A battery recycling harmless treatment device proposed in this scheme includes a nitrogen box, a filling cylinder, a crushing cylinder, a side-mounted crushing mechanism and an inserted air release mechanism. The filling cylinder is arranged on the upper wall of the nitrogen box, the crushing cylinder is arranged on the bottom wall of the filling cylinder, and the crushing cylinder is arranged with an upper opening. The side-mounted crushing mechanism is arranged on the side wall of the filling cylinder, and the inserted air release mechanism is arranged on the upper wall of the filling cylinder. The side-mounted crushing mechanism includes a filling mechanism, a pushing mechanism, a limiting mechanism and a crushing mechanism. The filling mechanism is arranged on the side wall of the filling cylinder, the pushing mechanism is arranged on the filling mechanism, the limiting mechanism is arranged at one end of the filling mechanism away from the pushing mechanism, the crushing mechanism is arranged on the crushing cylinder, the inserted air release mechanism includes a cooling mechanism, a drilling mechanism and an air supply mechanism. The cooling mechanism is arranged on the upper wall of the filling cylinder, the drilling mechanism is arranged on the side wall of the cooling mechanism, and the air supply mechanism is arranged inside the nitrogen box.

[0007] As a further preferred embodiment of the present invention, the filling mechanism includes a filling box, a sliding box, a locking frame, a locking bolt and an anti-slip bolt. Multiple groups of the filling boxes are arranged between the filling cylinder and the crushing cylinder. The filling box is arranged in a through manner. The sliding box is slidably arranged inside the filling 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 is arranged through the side wall of the filling box. The locking bolts are threadedly connected to the filling box. The anti-slip bolts are arranged in pairs on both sides of the filling box. The anti-slip bolts are threadedly connected to the filling box. The pushing mechanism includes a pushing magnetic plate, a pushing electromagnet and a pushing spring. The pushing magnetic plate The plate slides at one end of the sliding box close to the locking frame, the pushing electromagnet passes through the inner wall of the sliding box close to the pushing magnetic plate, and 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, the limiting groove is symmetrically arranged on the inner wall of the sliding box away from the locking frame, the limiting groove is open at one end, the limiting wedge is slidingly arranged inside the limiting groove, and the limiting spring is arranged between the limiting groove and the limiting wedge; the crushing mechanism includes a crushing motor, a crushing shaft and a crushing tool, the crushing motor is arranged on the upper wall of the crushing barrel, the crushing shaft passes through the crushing barrel and is arranged at the power end of the crushing motor, and multiple groups of crushing tools are arranged at the end of the crushing shaft away from the crushing motor.

[0008] When in use, rotate the locking bolt, the locking bolt is unscrewed from the side wall of the filling box, pull the locking frame, and the locking frame drives the sliding box to slide out along the inner wall of the filling box, and the batteries to be crushed are placed inside the sliding box through the upper opening of the sliding box. The batteries are stacked flatly inside the sliding box, the limit spring is set to be extended, and the distance between the limit wedges is the shortest value, which limits the batteries inside the sliding box and pushes the locking frame close to the side wall of the filling box, and screws the locking bolt into the filling box. The sliding box is fixed inside the filling box, and the pushing electromagnet is energized to generate magnetism. The pushing electromagnet and the pushing magnetic plate are set with the same pole. The pushing electromagnet is fixed to 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 in. When the battery reaches the inside of the crushing cylinder, since the contact surface between the limit wedge and the battery is inclined, after the battery contacts the limit wedge, the limit wedge shrinks into the limit groove using the deformation of the limit spring. At this time, the distance between the limit wedges is the maximum, which is convenient for the battery inside the sliding box to enter the crushing cylinder. The crushing tool is located between adjacent sliding boxes. The locking bolt is rotated and the locking bolt is unscrewed from the filling box. The sliding box is pulled out of the crushing cylinder through the locking frame. The crushing tool does not hit the sliding box during rotation. Since the side of the sliding box away from the crushing cylinder is closed, the inside of the crushing cylinder is sealed.

[0009] Preferably, the cooling mechanism includes a cooling box, a thermoelectric cooling sheet and a cold air port, the cooling box is arranged on the upper wall of the filling tube, the thermoelectric cooling sheet is arranged through the inner wall of the top of the cooling box, and multiple groups of cold air ports are arranged on the side wall of the cooling box; the drilling mechanism includes a drilling copper rod, a pressure rod plate, a drilling spring and a sealing ring, multiple groups of the drilling copper rods penetrate the filling tube and the crushing tube and are arranged on the side wall of one end of the cooling box near the cold air port, the pressure rod plate is arranged on the upper wall of the drilling copper rod, and the drilling spring is arranged on the pressure rod outside the drilling copper rod The plate and the cooling box are connected, and the sealing ring is arranged on the upper wall of the packing cylinder outside the drilled copper rod, and the inner diameter of the sealing ring is smaller than the outer diameter of the drilled copper rod; the air supply mechanism includes an air pump, an interception net, a nitrogen sensor and an exhaust valve, the air pump is arranged on the upper wall of the nitrogen box, the exhaust end of the air pump is connected to the crushing cylinder, the interception net is arranged through the inner wall of the bottom of the crushing cylinder, the exhaust valve is connected to 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 is arranged through the inside of the packing cylinder.

[0010] When in use, in the initial state, the drilling spring is in the extended setting, the tip of the drilling copper rod is located on the upper wall of the crushing cylinder, the thermoelectric cooling plate cools the air inside the cooling box through the cooling end, and the cold air inside the cooling box cools the drilling copper rod through the cold air port. The operator presses the drilling copper rod through the pressure rod plate, and the drilling copper rod uses the deformation of the drilling spring to penetrate the upper wall of the crushing cylinder and enter the sliding box. The drilling copper rod punctures the battery inside the sliding box, and then rotates the drilling copper rod, which drives the battery to deflect, and the drilling copper rod is pulled out of the battery.

[0011] Specifically, a controller is provided on the side wall of the nitrogen box.

[0012] Wherein, the controller is electrically connected to the pushing electromagnet, the crushing motor, the thermoelectric cooling sheet and the nitrogen sensor respectively.

[0013] Preferably, the model of the nitrogen sensor is SEN-EDL-2-N2.

[0014] The beneficial effects achieved by adopting the above structure are as follows:

[0015] Compared with the existing technology, this solution adopts a combination of puncture exhaust structure and low-temperature intervention structure. Through the side-mounted crushing mechanism and inserted degassing mechanism, under the mutual cooperation of the filling mechanism, pushing mechanism, limiting mechanism, crushing mechanism, cooling mechanism, drilling mechanism and air supply mechanism, it ensures that the battery is always in an oxygen-free environment during the crushing process, avoids oxidation reaction of the internal materials of the battery during the crushing process, ensures the recycling quality of the battery materials, and pre-punctures the battery to release the excessive gas generated in the battery due to overcharging, over-discharging, high temperature environment or improper use, avoiding the battery internal The gas flows into the inert environment after crushing, which improves the stability of the inert environment during the battery crushing process to a certain extent.

[0039] A controller 36 is provided on the side wall of the nitrogen box 1 .

[0040] The controller 36 is electrically connected to the pushing electromagnet 12 , the crushing motor 19 , the thermoelectric cooling plate 25 and the nitrogen sensor 34 , respectively.

[0041] The model of the nitrogen sensor 34 is SEN-EDL-2-N2.

[0042] When in use, in the initial state, the push spring 13 is in the compression setting, the limit spring 16 is in the extension setting, and the drilling spring 30 is in the extension setting. The locking bolt 9 is manually rotated, and the locking bolt 9 is screwed out from the side wall of the filling box 6. The locking frame 8 is pulled, and the locking frame 8 drives the sliding box 7 to slide out along the inner wall of the filling box 6. The batteries to be crushed are put into the sliding box 7 through the upper opening of the sliding box 7. The batteries are stacked flatly inside the sliding box 7. The distance between the limiting wedges 17 is the shortest value, which limits the batteries inside the sliding box 7. The locking frame 8 is pushed close to the side wall of the filling box 6, and the locking bolt 9 is screwed into the filling box 6. The sliding box 7 is fixed inside the filling box 6.

[0043] The tip of the drilling copper rod 28 is located on the upper wall of the crushing cylinder 3, and the controller 36 controls the thermoelectric cooling sheet 25 to start. The thermoelectric cooling sheet 25 cools the air inside the cooling box 24 through the cooling end, and the cold air inside the cooling box 24 cools the drilling copper rod 28 through the cold air port 26 to avoid thermal damage and short circuit risks caused by high-temperature puncture.

The drilling copper rod 28 punctures the battery inside the sliding box 7, and then rotates the drilling copper rod 28. The drilling copper rod 28 drives the battery to deflect, and 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. The drilling copper rod 28 is reset to the upper wall of the crushing cylinder 3 and placed;

[0044] The controller 36 controls the start-up of the air pump 32, which extracts nitrogen from the nitrogen box 1 through the air extraction end. The nitrogen enters the crushing cylinder 3 through the interception net 33, and the exhaust valve 35 is opened. The crushing cylinder 3 is connected to the outside through the exhaust valve 35. The nitrogen entering the crushing cylinder 3 gradually squeezes out the air inside it. The air inside the crushing cylinder 3 is discharged into the filling cylinder 2 through the through-hole of the drilled copper rod 28. The controller 36 controls the start-up of the nitrogen sensor 34. The nitrogen sensor 34 detects the gas discharged from the crushing cylinder 3 through the detection end. When the purity of the nitrogen meets the user's requirements, the exhaust valve 35 is closed to prevent the nitrogen from flowing out.

[0045] The controller 36 controls the push electromagnet 12 to start, and the push electromagnet 12 is energized to generate magnetism. The push electromagnet 12 and the push magnetic plate 11 are arranged with the same pole. The push electromagnet 12 is fixed to the inner wall of the sliding box 7 and pushes the push magnetic plate 11 by repulsion. The push magnetic plate 11 uses the push spring 13 to deform and push the battery inside the sliding box 7 into the crushing cylinder 3. Since the contact surface between the limit wedge 17 and the battery is inclined, after the battery contacts the limit wedge 17, the limit wedge 17 uses the deformation of the limit spring 16 to retract into the limit groove 15. At this time, the distance between the limit wedges 17 is the maximum, which facilitates the battery inside the sliding box 7 to enter the crushing cylinder 3.

[0046] The crushing tool 21 is located between adjacent sliding boxes 7. The locking bolt 9 is rotated, and the locking bolt 9 is screwed out of the filling box 6. The sliding box 7 is pulled out of the crushing cylinder 3 through the locking frame 8. The crushing tool 21 does not hit the sliding box 7 during the rotation. Since the side of the sliding box 7 away from the crushing cylinder 3 is closed, the interior of the crushing cylinder 3 is in a sealed state. The controller 36 controls the crushing motor 19 to start. The crushing motor 19 drives the crushing shaft 20 to rotate through the power end. The crushing shaft 20 drives the crushing tool 21 to crush the batteries inside the crushing cylinder 3; repeat the above operation when using it next time.

[0047] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0048] The above description of the present solution and its implementation methods is non-limiting. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present solution, designs a similar structure and embodiment without creatively designing, they shall fall within the scope of protection of the present solution.
