[0002] Compared with ordinary batteries, lithium-ion batteries have become increasingly popular in mobile phones, laptops, and other devices due to their high energy density, long cycle life, and lack of memory effect. Their application in new energy vehicles has also developed rapidly. At the same time, with the rapid growth in demand and application of lithium-ion batteries, a large number of retired lithium-ion batteries, i.e., waste lithium-ion batteries that need to be disposed of, will inevitably be generated. The waste slurry of lithium batteries contains high levels of precious metals such as nickel, cobalt, and lithium, which have high value. After baking, grinding, and other processes, the slurry can be transformed into a high-quality chemical raw material suitable for wet sulfuric acid systems.

[0003] However, existing black powder recovery devices for lithium battery waste slurry have the following drawbacks during use: low baking efficiency, slow speed, long waiting time, which affects the efficiency of subsequent processing. Therefore, there is room for improvement. Utility Model Content

[0019] The conveyor belt 110 is used to move the lithium battery waste slurry, and the drive motor 120 is used to drive the conveyor belt 110 to rotate.

[0020] The material frame 130 is fixed on the conveyor belt 110 and has a trapezoidal cross-section. A rectangular hole 131 is opened at the bottom of the material frame 130. The width of the rectangular hole 131 is slightly smaller than the width of the conveyor belt 110. With this setting, the lithium battery waste slurry in the material frame 130 can be spread flat on the conveyor belt 110 through the rectangular hole 131, increasing the drying area and enabling the waste slurry to be dried quickly.

[0021] The leveling component 140 is used to level the slurry on the conveyor belt 110 and control the thickness of the slurry. The leveling component 140 includes a bracket 141 fixed on the conveyor belt 110 and a scraper 142 fixed on the bracket 141. The bracket 141 is used to fix the scraper 142. The scraper 142 is inclined and used to level the slurry on the conveyor belt 110.

[0022] The drying unit 150 is used to dry the slurry. It includes a box 151 fixed on the conveyor belt 110 and a plurality of electric heating tubes 152 fixed in an array on the inner top wall of the box 151. The box 151 is made of heat-insulating material to form a closed environment to prevent heat loss. The electric heating tubes 152 are used to bake the slurry so that the slurry can be dried quickly.

[0023] The conical seat is fixed to the end of the conveyor belt 110, with its top end set in an arc shape and close to the surface of the conveyor belt 110, for scraping the dried slurry that has solidified into blocks off the conveyor belt 110.

[0024] The crushing mechanism 200 is used to crush the dried slurry, and includes a housing 210 disposed on one side of the conveyor belt 110, support legs 220 symmetrically fixed on both sides of the housing 210, a collection frame 230 fixed on the top of the housing 210 and communicating with the inner cavity of the housing 210, a screen 240 fixed on the inner wall of the housing 210, and a crushing component 250 fixed on the inner wall of the housing 210 and passing through the screen 240.

[0025] The shell 210 is cylindrical, and the support legs 220 are used to form the shell 210 to ensure its stability. A discharge port 211 is provided at the bottom of the shell 210 to deliver the black powder. The collection frame 230 is used to collect the blocky dry slurry scraped out by the scraper seat 160 and guide it into the inner cavity of the shell 210.

[0026] Screen 240 is used to screen the pulverized dried slurry. Materials smaller than the aperture of screen 240 pass through screen 240 and are discharged through outlet 211.

It includes a first motor 251 fixed to the inner wall of the housing 210 by a support rod and whose shaft passes through the screen 240, and blades 252 fixed in a ring array on the shaft of the first motor 251. When the first motor 251 is started, it drives the blades 252 to rotate. The rotating blades 252 crush the blocky dry slurry to form black powder.

[0028] The working principle and usage process of this utility model are as follows: In use, waste lithium battery slurry is poured into the material frame 130. The waste slurry in the material frame 130 is then spread evenly on the top of the conveyor belt 110 through the rectangular hole 131 at the bottom of the material frame 130. The drive motor 120 is started, causing the conveyor belt 110 to rotate. The rotation of the conveyor belt 110 moves the waste slurry. When it passes the scraper 142, the waste slurry on the conveyor belt 110 is scraped flat by the scraper 142 and then enters the housing 151. The heating element 152 is activated to bake the waste slurry on the conveyor belt 110, drying it. The dried waste slurry continues to move forward with the conveyor belt 110, and under the action of the scraper seat 160, it is dried into blocks. The slurry is scraped off from the conveyor belt 110 and falls into the collection frame 230. Under the action of the collection frame 230, it is collected into the inner cavity of the housing 210. At this time, the first motor 251 starts and drives the blade 252 to rotate, crushing the blocky dry slurry into black powder. The black powder smaller than the aperture of the screen 240 passes through the screen 240 and is discharged through the discharge port at the bottom of the housing 210, realizing the recycling of black powder. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
