[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0023] like Figure 1 and Figure 4As shown, this utility model can be implemented through the following embodiments: A recycling device for crushing lithium batteries includes a body 1, a crushing chamber 11 inside the body 1, a crushing roller 111 installed inside the crushing chamber 11, a sliding groove 12 on the body 1, a water tank 13 below the sliding groove 12, a fixing frame 2 installed on the sliding groove 12, a hydraulic cylinder 21 installed on the fixing frame 2, a fixing plate 211 on the hydraulic cylinder 21, a spike 212 fixed on the fixing plate 211, a material support plate 3 installed inside the sliding groove 12, the material support plate 3 and the sliding groove 12 are connected by a screw 4, a feed inlet 122 and a liquid outlet channel 121 are opened at the bottom of the sliding groove 12, the feed inlet 122 is connected to the crushing chamber 11, the liquid outlet channel 121 is connected to the water tank 13, a drying box 5 is arranged below the crushing chamber 11, a fine crushing chamber 6 is opened below the drying box 5, and a collection box 7 is installed below the fine crushing chamber 6.
[0024] The receiving plate 3 is used to place waste lithium batteries, which are fed into the machine body 1 by rotating the lead screw 4; the hydraulic cylinder 21 on the fixed frame 2 drives the fixed plate 211 and the spike 212, which pierces the waste lithium battery, causing the electrolyte inside the waste lithium battery to flow out; the liquid outlet channel 121 is used to collect the outflowing electrolyte into the water tank 13 for storage, and the feed port 122 is used to send the waste lithium battery with discharged electrolyte into the crushing chamber 11 for crushing; the drying box 5 is used to dry the residual moisture on the lithium battery fragments to prevent the fragments from sticking together under the action of moisture; the fine crushing chamber 6 crushes the fragments into particles of qualified diameter, and the collection box 7 is used to collect the crushed particles.
[0025] like Figure 1 and Figure 2 As shown, compression cylinders 22 are installed on the left and right sides of the fixed frame 2, and a light control switch 23 is set below the compression cylinders 22. A mounting frame 14 is set at the feed inlet 122, and a clamping cylinder 141 is installed on the mounting frame 14. The compression cylinders 22 are used to apply pressure to the lithium batteries after the waste lithium batteries are pierced by the piercing cone 212, so as to accelerate the outflow of electrolyte and improve production efficiency. The light control switch 23 is used to control the material support plate 3 to stop at the fixed frame 2 and to pierce the waste lithium batteries without manual control. The clamping cylinder 141 is used to fix the waste lithium batteries so that after the material support plate 3 returns, the waste lithium batteries are fed into the feed inlet 122.
[0026] like Figure 1 As shown, a rectangular through hole 31 is provided on the material support plate 3. The rectangular through hole 31 is designed to facilitate the piercing cone 212 to pierce the waste lithium battery, and at the same time, it facilitates the electrolyte to flow into the water tank 13 through the rectangular through hole 31 from the liquid outlet channel 121.
[0027] like Figure 2 and Figure 3As shown, a rotating shaft 51 is installed inside the drying chamber 5, and a stirring blade 511 is installed on the rotating shaft 51. The rotating shaft 51 is connected to a motor 512, and an electric heating wire 53 is laid inside the drying chamber 5. The rotating shaft 51 is used to rotate the lithium battery fragments entering the drying chamber 5, and the stirring blade 511 stirs the lithium battery fragments to prevent them from sticking together. The electric heating wire 53 dissipates heat to remove moisture from the lithium battery fragments, which facilitates the further fine crushing of the lithium battery fragments.
[0028] like Figure 2 As shown, the drying chamber 5 has two discharge ports 52, and each discharge port 52 is equipped with a gate 8, which is connected to a hydraulic cylinder 81. The two discharge ports 52 facilitate the improvement of discharge efficiency; the gate 8 prevents lithium battery fragments containing moisture from falling into the fine crushing chamber 6 from the discharge ports 52 when the drying chamber 5 is stirring the lithium battery fragments; the hydraulic cylinder 81 controls the opening and closing of the gate 8.
[0029] like Figure 2 As shown, there are two gates 8 and two discharge ports 52, and two fine crushing chambers 6. An inclined screen plate 61 is installed between the fine crushing chamber 6 and the collection box 7, and the inclined screen plate 61 has screen holes 611. The number of fine crushing chambers 6 is the same as that of gates 8 and discharge ports 52, which are used to receive lithium battery fragments from the drying box 5 to improve production efficiency; the screen holes 611 on the inclined screen plate 61 are used to screen out suitable particles.
[0030] like Figure 2 As shown, a transport chamber 62 is provided next to the fine crushing chamber 6, and an auger structure 621 is installed in the transport chamber 62. Lithium battery fragments falling along the inclined screen plate 61 will enter the transport chamber 62, and the lithium battery fragments will be driven back to the fine crushing chamber 6 by the auger structure 621 in the transport chamber 62 to be crushed again until the fragments become suitable particles and are collected by the collection box 7.
[0031] like Figure 2 As shown, an mounting plate 9 is provided between the inclined screen plates 61, and a vibration motor 10 is mounted on the mounting plate 9. The mounting plate 9 is connected to the inclined screen plate 61 and the vibration motor 10 is mounted thereon. When the vibration motor 10 is working, it vibrates to remove the residual lithium battery fragments on the screen plate, so that the lithium battery fragments enter the transport chamber 62, preventing the residual lithium battery fragments from affecting the normal operation of the inclined screen plate 61.
[0032] like Figure 1 and Figure 4 As shown, the collection box 7 has a groove 71, and a handle 72 is installed in the groove 71. The handle 72 is connected to the collection box 7 via a rotating rod 721. The handle 72 makes it easy for workers to take out the collection box 7, and the rotating rod 721 makes the handle 72 and the collection box 7 rotatably connected, making it easy for users to apply force to drag the collection box 7.
[0033] The working principle of this utility model is as follows: A fixed quantity of waste lithium batteries is stacked on the support plate 3. The starter screw 4 moves the support plate 3 to the feed inlet 122. When it passes the fixing frame 2, the light control switch 23 senses the change in light and sends a signal. At the same time, the hydraulic cylinder 21 starts rotating, and the piercing cone 212 moves downward to pierce the waste lithium batteries, causing the electrolyte to flow out. The squeezing cylinder 22 starts squeezing the waste lithium batteries to accelerate the outflow of electrolyte. The outlet channel 121 collects the outflowing electrolyte and flows into the water tank 13. After the support plate 3 reaches the feed inlet 122, the clamping cylinder 141 starts and clamps the waste lithium batteries. When the lead screw 4 reverses, it drives the material support plate 3 to return. After the clamping cylinder 141 is released, the waste lithium battery enters the crushing chamber 11. The crushing roller 111 in the crushing chamber 11 crushes the lithium battery into fragments. The fragments enter the drying box 5. After the drying box 5 dries the moisture on the fragments, the hydraulic cylinder 81 drives the gate 8 to open the discharge port 52. The fragments enter the fine crushing chamber 6 for further crushing along the discharge port 52. Suitable particles enter the collection box 7 through the discharge port 52 on the inclined screen plate 61. The fragments that are not completely crushed enter the transport chamber 62 along the inclined screen plate 61 and enter the crushing chamber 11 again for crushing through the auger structure 621.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
