[0031] Example 1

[0032] Reference Figures 1 to 7The present embodiment provides a decommissioned lithium battery recycling device capable of adjusting the particle size of crushed materials, including a shell 100, an inner groove 100a is provided inside the shell 100, and a first servo motor 101 is fixedly connected inside the shell 100; a crushing mechanism 200, the crushing mechanism 200 includes a first crushing roller 201 and a second crushing roller 202, and the first crushing roller 201 and the second crushing roller 202 rotate inside the inner groove 100a; a filtering mechanism 300, the filtering mechanism 300 includes a filter cartridge 301 and an adjusting cartridge 302, the filter cartridge 301 rolls inside the inner groove 100a, and the adjusting cartridge 302 is rotatably connected to the outer wall of the filter cartridge 301; a cleaning mechanism 400, the cleaning mechanism 400 includes a cleaning roller 401, and the cleaning roller 401 cooperates with the filtering mechanism 300.

[0033] The outer walls of the first crushing roller 201 and the second crushing roller 202 are both provided with a plurality of crushing teeth 201a, and the first crushing roller 201 and the second crushing roller 202 are rollingly connected to each other through gears, and the first crushing roller 201 and the second crushing roller 202 are both fixed to the outer shell 100 and rollingly connected inside the inner groove 100a through bearings; the batteries are crushed by the mutual rolling connection of the first crushing roller 201 and the second crushing roller 202 and by a plurality of groups of crushing teeth 201a provided on the outer walls of the first crushing roller 201 and the second crushing roller 202.

[0034] A slide groove 301b is provided at one end of the outer wall of the filter cartridge 301, and at least two groups of support rollers 100c are arranged inside the inner groove 100a. Several groups of support rollers 100c are engaged with the slide groove 301b of the filter cartridge 301 and are rollingly connected; the function of several groups of support rollers 100c is to fix the filter cartridge 301.

[0035] A plurality of first filter holes 301c are formed through the outer wall of the filter cylinder 301, and a plurality of material retention plates 301a are fixedly connected to the inner wall of the filter cylinder 301; the first filter holes 301c are used to screen the crushed materials, thereby retaining large crushed materials inside the filter cylinder 301, and as the filter cylinder 301 rotates, the large materials are re-fed to the crushing mechanism 200 through the material retention plates 301a for further crushing.

[0036] The outer wall of the adjusting cylinder 302 is penetrated by a second filter hole 302a having the same number as the first filter hole 301c. The adjusting cylinder 302 controls the overlap degree of the second filter holes 302a and the first filter holes 301c by rotating, thereby adjusting the size of the sieve holes. The size of the sieve holes is proportional to the overlap area of ​​the second filter holes 302a and the first filter holes 301c.

[0037] A plurality of groups of dredging rods 402 are fixedly connected to the outer wall of the cleaning roller 401, and the dredging rods 402 cooperate with the first filter hole 301c of the filter cylinder 301; when the cleaning roller 401 and the filter mechanism 300 rotate synchronously, the rotating cleaning roller 401 drives the plurality of groups of dredging rods 402 to rotate, and the rotating dredging rods 402 penetrate the first filter hole 301c on the outer wall of the filter cylinder 301 and the second filter hole 302a of the adjustment cylinder 302, thereby achieving the purpose of dredging.

[0038] A discharge port 100b is provided at the bottom of the housing 100; the purpose of the discharge port 100b is to discharge the shredded materials that have been filtered through their own gravity.

[0039] The first crushing roller 201, the second crushing roller 202, the filter drum 301 and the cleaning roller 401 all achieve synchronous rotation through gears. The first servo motor 101 is fixedly connected to any one of the first crushing roller 201, the second crushing roller 202, the filter drum 301 and the cleaning roller 401 and makes them rotate. The first servo motor 101 makes the first crushing roller 201, the second crushing roller 202, the filter drum 301 and the cleaning roller 401 rotate synchronously; when the first crushing roller 201 rotates, the second crushing roller 202 and the filter drum 301 are driven to rotate through the gears. At this time, the rotation direction of the first crushing roller 201 is opposite to that of the second crushing roller 202, and is the same as that of the filter drum 301. When the filter drum 301 rotates, the cleaning roller 401 is rotated through the gears. At this time, the rotation directions of the filter drum 301 and the cleaning roller 401 are opposite.

[0040] Working principle: Turn on the power supply to start the first servo motor 101 to work, and the first servo motor 101 is used to rotate any one of the first crushing roller 201, the second crushing roller 202, the filter cartridge 301 and the cleaning roller 401. When the first crushing roller 201 rotates, the second crushing roller 202 and the filter cartridge 301 are driven to rotate synchronously through the gears, and the batteries to be crushed are put into the top of the crushing mechanism 200 inside the filter cartridge 301, and the batteries are shredded by the first crushing roller 201 and the second crushing roller 202 that roll against each other. After shredding, the smaller materials will pass through the first filter hole 301c of the filter cartridge 301 and the second filter hole 302a of the adjustment cartridge 302 in turn and be discharged from the discharge port 100b. When the material size is larger than the first filter hole 301c, it will be retained in the filter cartridge 301. The rotation of the filter cylinder 301 brings the material to the top of the filter cylinder 301 through the material retention plate 301a and drops it, and the crushing mechanism 200 crushes it again until the material meets the size requirements. When the filter cylinder 301 rotates, the cleaning roller 401 is driven to rotate through the gear, and the cleaning roller 401 drives several groups of dredging rods 402 to rotate. The rotating several groups of dredging rods 402 penetrate the first filter hole 301c and the second filter hole 302a to dredge the first filter hole 301c and the second filter hole 302a. When it is necessary to adjust the size of the crushed material, the adjusting cylinder 302 is rotated to control the overlap degree of the first filter hole 301c and the second filter hole 302a. When the overlap area of ​​the first filter hole 301c and the adjusting cylinder 302 is smaller, the size of the filtered material will also be smaller. In this way, the size of the crushed material is controlled.
