Description

Technical Field

[0001] The invention relates to the technical field of crushing and sorting, and in particular to a crushing and sorting device and method for recycling waste lithium batteries. Background Art

[0002] As an indispensable way of storing electric energy in modern society, lithium batteries have provided great convenience for people's lives. As the number of times lithium batteries are charged and discharged increases, the amount of electric energy stored in lithium batteries will gradually decay. When the electric energy of lithium batteries decays to a certain extent, they need to be replaced. If the replaced waste lithium batteries cannot be processed, it will have a great impact on the environment. Non-ferrous metals such as cobalt, lithium and nickel in waste lithium batteries are important resources and have extremely high recycling value. Therefore, waste lithium batteries need to be recycled. In the recycling of waste lithium batteries, the most important thing is crushing and physical sorting. After the crushing and physical sorting are completed, it will be convenient for the staff to recycle the waste lithium batteries later.

[0003] like Figure 1 As shown, most of the existing waste battery recycling and processing methods are to place the waste batteries at the feeding port of the processing box, and then crush the waste batteries through a crushing roller. The crushed waste batteries fall on the top of the screening net, and the screening effect is increased by arranging components such as vibrators on the screening net, so as to complete the screening of the waste batteries. The screened battery debris is then passed through an electromagnet to remove ferromagnetic materials, and the non-ferromagnetic materials enter the collection box for collection. When this method is used, it is not convenient to repeat the crushing of the battery debris screened out from the top of the filter net in a timely manner, so that the top of the filter net is easily blocked, thereby affecting the normal operation of the waste battery processing equipment.

[0004] The announcement number is: CN112675980B, which discloses a crushing and sorting device for recycling waste lithium batteries. The sorting device can screen the crushed fragments through the cooperation of a beating mechanism, a crushing mechanism and a screening mechanism, and then put the larger fragments back into the discharge frame for secondary crushing. The iron filings of the fragments can be separated from the fragments through the cooperation of a feeding mechanism, a magnetic suction mechanism, a collecting mechanism and a pulling mechanism. The above-mentioned sorting device can only sort magnetic materials when performing sorting work, and after the above-mentioned sorting device intercepts the fragments that do not meet the screening size on the screening frame, it is necessary to manually take out the fragments for re-crushing, so that in actual production, the crushing device needs to be stopped before operation can be performed, which makes it inconvenient to carry out continuous production when in use, and requires the staff to watch the screening frame at any time, which not only affects the work efficiency, but also increases the workload of the staff.

[0005] At the same time, lithium batteries mainly include: positive electrode materials, negative electrode materials, diaphragms and electrolyte powders. During crushing and screening, the above-mentioned crushing and sorting device can only screen magnetic materials, which makes it inconvenient to screen powder materials and diaphragms at the same time in actual production. When the above-mentioned crushing and sorting device is used for sorting, the powder materials, diaphragms and copper and aluminum materials will be mixed together, and other devices will need to be used for multiple sorting.

[0006] Based on this, a crushing and sorting device and method for recycling waste lithium batteries are now provided, which can eliminate the disadvantages of existing devices. Summary of the invention

The crushing and sorting equipment for recycling waste lithium batteries according to claim 9, characterized in that: A dredging rod (35) is provided below the hopper (31), and mounting frames are fixedly provided at both ends of the dredging rod (35), and a third guide slide is fixedly provided on one side of the mounting frame, and the third guide slide is slidably provided in a sliding hole inside the mounting main box (11), and a top rod (36) is symmetrically provided on one side of the mounting frame, and a guide plate (37) is tightly provided at one end of the top rod (36), and a plurality of guide blocks are arranged in an array on one side of the guide plate (37), and the guide blocks on the two guide plates (37) are alternately arranged, and a second fixed shaft is provided on one side of the guide plate (37), and the two second fixed shafts are transmission-connected to the two ends of the second active crushing roller (39) through a sixth belt.

11. A method for using the crushing and sorting equipment for recycling waste lithium batteries according to claim 10, characterized in that: The steps include: Step 1, the first active crushing roller (14) and the first driven crushing roller (15) crush the lithium battery, the first conveyor belt (20) transmits the crushed lithium battery, the bidirectional auger (23) spreads the lithium battery on the upper end of the first conveyor belt (20), and under the action of the first electromagnet (21) and the permanent magnet (22), the magnetic material is adsorbed, and the magnetic material falls on the upper end of the second screening plate (25), and the non-magnetic material and the powder material both fall on the upper end of the first screening plate (24), and the powder material is sorted by the first screening plate (24) and the second screening plate (25) and then falls into the second collection box (30) through the guide plate (29) for collection; Step 2: The second active crushing roller (39) and the second driven crushing roller (40) perform secondary crushing on the lithium battery, and the lithium battery falls from the discharge end of the second crushing box (38). The fan (46) is started, and the wind discharged from the exhaust pipe (45) blows the diaphragm material into the separation box (47). At the same time, the third motor (52) is started, and the scraper (50) scrapes the diaphragm material and stores it in the third collection box (49); Step 3, the third screening plate (43) screens the material, and unqualified non-magnetic materials enter the transmission pipe (53) through the discharge pipe. The auger plate (54) transports the material, and the material is discharged into the hopper (31) through the return pipe for further crushing and sorting.
