Description

Technical Field

[0001] The utility model relates to the field of lithium battery recycling, in particular to an impurity removal reaction device for recycling waste lithium batteries. Background Technique

[0002] When recycling useful resources in waste lithium batteries, impurities and harmful substances in the crushed waste batteries can be removed through screening equipment, so that the recycled lithium battery materials are purer, reducing environmental pollution. In addition, the utilization rate of resources is increased, which conforms to the concept of green environmental protection.

[0003] Currently, in the process of removing impurities from crushed lithium batteries, usually the dirt and adhesives on their surfaces are removed first, and then the lithium batteries are vibrated and screened. However, this impurity removal method will increase the length of the production line, not only increasing the cost but also reducing the cleaning time. In addition, it is necessary to repeatedly remove dirt and vibrate and screen later, which further increases the operation complexity and thus reduces the cleaning efficiency. Therefore, an impurity removal reaction device for recycling waste lithium batteries is proposed for the above problems. Content of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and avoid the problem of reduced cleaning efficiency, the utility model proposes an impurity removal reaction device for recycling waste lithium batteries.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an impurity removal reaction device for recycling waste lithium batteries, including a screening machine device; a screening component is arranged at the top of the screening machine device, and a dirt removal component is arranged on the left side of the top of the screening machine device;

[0006] The screening component includes two drainage holes opened on the front and rear sides of the top of the screening machine device. A sliding plate is slidably connected to the top of the screening machine device. An electromagnet is fixedly installed on the top of the sliding plate. A discharge pipe is fixedly installed on the right side of the top of the screening machine device.

[0007] Preferably, the drainage holes penetrate through the upper and lower sides of the top of the screening machine device. When the water flow for cleaning the waste batteries flows into the interior of the screening machine device, the water flow will be discharged to the bottom of the screening machine device through the drainage holes. The bottom end of the discharge pipe penetrates through the screening machine device and extends below the screening machine device, and the screened batteries are collected through the discharge pipe.

[0008] Preferably, the decontamination component includes a support rod fixedly installed at the left top end of the screening machine device. The top end of the support rod is fixedly installed with a cleaning box. The top of the cleaning box is rotatably connected with a driving rod. The surface of the driving rod is provided with a water flow circulation component. The inner wall of the cleaning box is fixedly installed with a fixed hollow cavity. One end of the fixed hollow cavity close to the middle of the cleaning box is provided with an annular groove. The top of the fixed hollow cavity is fixedly installed with an external pipeline. Both the left and right sides of the top end of the cleaning box are fixedly installed with water baffle plates.

[0009] Preferably, the end face of the driving rod is fixedly installed with the driving shaft of the motor, and the driving shaft can be operated to drive the driving rod to rotate. The inside of the external pipeline and the annular groove are communicated.

[0010] Preferably, the water flow circulation component includes a hollow annular sleeve fixedly installed on the surface of the driving rod. The surface of the hollow annular sleeve is fixedly installed with a hollow stirring rod. Through holes are arranged on the surface of the hollow stirring rod. The surface of the hollow annular sleeve is fixedly connected with a hollow connecting pipe. One end of the hollow connecting pipe close to the inner wall of the cleaning box is fixedly installed with a connecting pipeline. One end of the connecting pipeline away from the hollow connecting pipe is fixedly installed with a fixed sleeve.

[0011] Preferably, the hollow annular sleeves are arranged at equal intervals on the surface of the driving rod. The hollow annular sleeve and the hollow stirring rod are communicated. The hollow annular sleeve and the hollow connecting pipe are alternately communicated in sequence. After the water flows into the inside of the hollow connecting pipe, it will pass through the hollow annular sleeve and the hollow stirring rod, and then the water is sprayed onto the surface of the waste battery through the through holes, thereby cleaning the waste battery.

[0012] Preferably, the connecting pipeline and the hollow connecting pipe are communicated. One end of the connecting pipeline away from the hollow connecting pipe penetrates through the fixed sleeve and extends into the inside of the connecting pipeline. The connecting pipeline is slidably connected inside the annular groove and communicated with the external pipeline. The fixed sleeve is rotatably connected to the surface of the fixed hollow cavity. The water flowing into the inside of the fixed hollow cavity is blocked by the fixed sleeve. At this time, the water can only enter the inside of the hollow connecting pipe through the annular groove and the connecting pipeline.

[0013] The beneficial effects of the present invention are as follows:

[0014] After the waste battery is placed inside the cleaning box in the present invention, the rotating hollow stirring rod and the sprayed water flow stir and clean the waste battery at this time, so as to clean the dirt and adhesions on the surface of the waste battery, making the cleaning efficiency of the waste battery relatively high; and the cleaned waste battery is directly introduced to the top of the screening machine device through the bottom end of the cleaning box. At this time, the screening machine device screens the waste battery, and at the same time, the magnetic materials in the waste battery are adsorbed and collected through the electromagnet, thereby improving the separation efficiency of the materials.

[0024] The following further elaborates on this application in conjunction with the attached Figure 1 —6,

[0025] This application example discloses an impurity removal reaction device for recycling waste lithium batteries. Refer to Figure 1 , the impurity removal reaction device for recycling waste lithium batteries includes a screening machine device 1; a screening component 2 is arranged at the top of the screening machine device 1, and a decontamination component 3 is arranged on the left side of the top of the screening machine device 1;

[0026] Refer to Figure 1 - Figure 2 , the screening component 2 includes two drain holes 21 opened on the front and rear sides of the top of the screening machine device 1. A sliding plate 22 is slidably connected to the top of the screening machine device 1. An electromagnet 23 is fixedly installed at the top of the sliding plate 22. A discharge pipe 24 is fixedly installed on the right side of the top of the screening machine device 1. The drain holes 21 penetrate through the upper and lower sides of the top of the screening machine device 1. When the water flow for cleaning the waste batteries flows into the interior of the screening machine device 1, at this time, the water flow will be discharged to the bottom of the screening machine device 1 through the drain holes 21. The bottom end of the discharge pipe 24 penetrates through the screening machine device 1 and extends to the lower part of the screening machine device 1. The screened batteries are collected through the discharge pipe 24.

[0027] Refer to Figure 2 - Figure 5 , the decontamination component 3 includes a support rod 31 fixedly installed at the left top of the screening machine device 1. A cleaning box 32 is fixedly installed at the top of the support rod 31. A driving rod 33 is rotatably connected to the top of the cleaning box 32. A water flow circulation component 34 is arranged on the surface of the driving rod 33. A fixed hollow cavity 35 is fixedly installed on the inner wall of the cleaning box 32. An annular groove 36 is opened at one end of the fixed hollow cavity 35 close to the middle of the cleaning box 32. An external pipeline 37 is fixedly installed at the top of the fixed hollow cavity 35. The end face of the driving rod 33 is fixedly installed with the driving shaft of the motor, and the driving shaft can be operated to drive the driving rod 33 to rotate. The inside of the external pipeline 37 and the annular groove 36 are communicated. Water baffle plates 38 are fixedly installed on the left and right sides of the top of the cleaning box 32.

[0028] Refer to Figure 3 - Figure 6, the water flow circulation component 34 includes a hollow annular sleeve 341 fixedly installed on the surface of the driving rod 33. The surface of the hollow annular sleeve 341 is fixedly installed with a hollow stirring rod 342. Through holes 343 are formed on the surface of the hollow stirring rod 342. The surface of the hollow annular sleeve 341 is fixedly connected with a hollow connecting pipe 344. The hollow annular sleeves 341 are arranged at equal intervals on the surface of the driving rod 33. The hollow annular sleeve 341 communicates with the hollow stirring rod 342. The hollow annular sleeve 341 and the hollow connecting pipe 344 communicate with each other alternately. After the water flow enters the interior of the hollow connecting pipe 344, it will pass through the hollow annular sleeve 341 and the hollow stirring rod 342, and then the water flow is sprayed onto the surface of the waste battery through the through holes 343, thereby cleaning the waste battery. One end of the hollow connecting pipe 344 close to the inner wall of the cleaning box 32 is fixedly installed with a connecting pipe 345. One end of the connecting pipe 345 away from the hollow connecting pipe 344 is fixedly installed with a fixed sleeve 346. The connecting pipe 345 communicates with the hollow connecting pipe 344. One end of the connecting pipe 345 away from the hollow connecting pipe 344 penetrates through the fixed sleeve 346 and extends into the interior of the connecting pipe 345. The connecting pipe 345 is slidably connected inside the annular groove 36 and communicates with the external pipeline 37. The fixed sleeve 346 is rotatably connected to the surface of the fixed hollow cavity 35. The water flow entering the interior of the fixed hollow cavity 35 is blocked by the fixed sleeve 346. At this time, the water flow can only enter the interior of the hollow connecting pipe 344 through the annular groove 36 and the connecting pipe 345.

[0029] Working principle: The operator places the crushed lithium battery inside the cleaning box 32. At this time, an external pipeline 37 is connected to the water outlet of an external water pump. Then, the driving motor and the water pump are driven. The motor drives the driving rod 33 to rotate. At this time, the driving rod 33 drives the fixedly connected hollow annular sleeve 341 to rotate, and the hollow annular sleeve 341 drives the hollow stirring rod 342 to rotate. At this time, the hollow stirring rod 342 stirs the lithium battery inside the cleaning box 32. At the same time, the water pump pumps water into the internal of the external pipeline 37. At this time, the water flows into the surface of the fixed hollow cavity 35 fixed inside the cleaning box 32 through the external pipeline 37. And when the driving rod 33 rotates, it drives the hollow annular sleeve 341 and the hollow connecting pipe 344 to rotate accordingly. At this time, the hollow connecting pipe 344 drives the fixed connecting pipeline 345 and the fixed sleeve 346 to rotate. At this time, the fixed sleeve 346 rotates on the surface of the fixed hollow cavity 35, and at this time, the fixed sleeve 346 blocks the annular groove 36 to prevent the water inside the fixed hollow cavity 35 from being directly discharged through the annular groove 36. Then, the water inside the fixed hollow cavity 35 enters the internal of the hollow connecting pipe 344 through the connected connecting pipeline 345. At this time, the water flows inside the hollow connecting pipe 344 towards the hollow annular sleeve 341, and then is discharged through the hollow stirring rod 342 and the through hole 343. At this time, the water will be sprayed through the through hole 343 towards the stirred lithium battery, thereby removing the dirt and adhesives on the surface of the lithium battery. Then, the cleaned lithium battery will fall to the top of the screening machine device 1 through the bottom of the cleaning box 32.

[0030] Then, the operator drives the screening machine device 1 to vibrate. The vibrating screening machine device 1 drives the lithium battery to move to the right on the surface of the screening machine device 1. The lithium battery is screened during the movement. At the same time, the operator energizes the electromagnet 23. At this time, the electromagnet 23 attracts the magnetic materials of the moving lithium battery, so that the magnetic materials are adsorbed to the top wall of the sliding plate 22. And the screened lithium battery will fall into the internal of the discharge pipe 24 to be collected. Then, the operator can remove the sliding plate 22 and remove the adhered magnetic materials from the top wall of the sliding plate 22 for further collection.

[0031] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
