Description

Technical Field

[0001] The invention relates to the technical field of lithium battery material processing, in particular to a cone mill. Background Art

[0002] Lithium battery materials refer to the components used to manufacture lithium-ion batteries, including positive electrodes (such as lithium cobalt oxide and lithium nickel cobalt manganese oxide), negative electrodes (graphite), electrolytes and separators. Lithium battery materials are recycled because the metal resources such as lithium, cobalt and nickel contained in them are scarce and of high value. Recycling can save resources, reduce environmental pollution, and at the same time alleviate dependence on primary minerals and promote sustainable development. In the recycling process, copper and zinc are isolated because they are related to the battery structure. When lithium batteries are crushed and immersed in chemical solutions, copper and zinc will dissolve and enter the solution together with metals such as cobalt and nickel. Copper and zinc in the solution will affect the dissolution efficiency of the target metal, and copper and zinc may form similar compounds or precipitates with cobalt and nickel, making separation complicated.

[0003] Existing crushers cannot crush lithium batteries quickly and effectively when processing them, which limits the processing speed of lithium batteries and increases the processing time of lithium batteries. Since iron accounts for a high proportion of the mass of lithium batteries, iron impurities need to be removed when recycling other more valuable metals (such as cobalt, nickel and lithium) to prevent them from affecting the purity and performance of the final product. Existing crushers are prone to wear when processing hard battery materials, which may require frequent replacement of blades or other key components of existing crushers, reducing recycling efficiency and increasing maintenance costs.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0025] Cone mill, such as Figure 1-Figure 9As shown, it includes a bracket 1, a first motor 2, a cylinder 3, an outer cylinder 301, a first connecting plate 302, a feed pipe 4, an inner cylinder 5, a second connecting plate 51, an adjusting mechanism, a rotating shaft 6, a conical grinding disc 7, a lower hopper 8 and a filtering mechanism. The first motor 2 is installed on the left side of the bracket 1, the top of the bracket 1 is fixedly connected to the outer cylinder 301, the top of the outer cylinder 301 is fixedly connected to the feed pipe 4, the feed pipe 4 is a hose and is connected to the discharge part of the previous process, the feed pipe 4 passes through the top of the outer cylinder 301, and the maximum inner diameter of the bottom of the feed pipe 4 is two hundred mm, the outer side of the top of the outer cylinder 301 is fixedly connected with a first connecting plate 302, the right side of the bracket 1 is fixedly connected with the cylinder 3, the bottom of the cylinder 3 is fixedly connected with a lower hopper 8, the lower hopper 8 is connected with the cylinder 3, and the bottom of the lower hopper 8 is connected with a filtering mechanism, the inner cylinder 5 is slidably installed on the outer cylinder 301, the inner wall of the inner cylinder 5 is provided with a ceramic lining, the inner cylinder 5 is connected with the feed pipe 4 and the cylinder 3 respectively, the top and the outside of the inner cylinder 5 are fixedly connected with a second connecting plate 51, and a The adjusting mechanism for adjusting the discharge gap is used. The inside of the cylinder 3 is rotatably connected with the rotating shaft 6 through the bearing seat. The connection between the rotating shaft 6 and the cylinder 3 is made of 304 stainless steel coated with a nano-ceramic coating to avoid copper and zinc pollution. The output shaft of the first motor 2 is connected to the rotating shaft 6 through a synchronous belt transmission. A shielding cover is provided at the transmission connection between the first motor 2 and the rotating shaft 6 to prevent the lithium battery material from interfering with the use of the transmission belt. The top of the rotating shaft 6 is sealed and connected with a conical grinding disc 7. The rotating shaft 6 and the conical grinding disc 7 are connected by a sealing seat and a ceramic material. The labyrinth sealing plate is sealed and connected, the conical grinding disc 7 includes a grinding core lining and a grinding core ceramic sleeve mounted on the grinding core lining, the conical grinding disc 7 is set to be made of zirconium oxide material, the tip of the conical grinding disc 7 faces upward, and the outer side of the conical grinding disc 7 is provided with circular and strip-shaped protrusions, which can increase the friction between the conical grinding disc 7 and the lithium battery material and improve the crushing speed of the conical grinding disc 7. The conical grinding disc 7 is located inside the inner cylinder 5, and a gap is left between the bottom of the conical grinding disc 7 and the bottom of the inner cylinder 5 for the crushed material to flow out, and the size of the gap is one millimeter.

[0026] When the lithium battery material is crushed, the lithium battery material is passed through the feed pipe 4 into the inner cylinder 5, and the motor drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 causes the conical grinding disc 7 to rotate, and the lithium battery material is crushed by the mutual friction between the conical grinding disc 7 and the inner cylinder 5. The lithium battery material moves downward from the upper part of the inner cylinder 5 to the lower part of the inner cylinder 5, so that the conical grinding disc 7 crushes the lithium battery material step by step, so that the lithium battery material falls into the cylinder body 3 through the gap between the conical grinding disc 7 and the inner cylinder 5, and the lithium battery material in the cylinder body 3 falls out from the lower hopper 8, and then is filtered by the filtering mechanism. The distance between the first connecting plate 302 and the second connecting plate 51 is controlled by the adjusting mechanism, so that the height difference between the inner cylinder 5 and the conical grinding disc 7 can be controlled, thereby the particle size of the lithium battery material falling into the cylinder body 3 can be adjusted, thereby improving the crushing and recovery efficiency of the lithium battery material.

[0027] like Figure 1 and Figure 4 As shown, the adjustment mechanism includes a threaded rod 9, a sleeve 10 and a first elastic member 11. Four threaded rods 9 are rotatably connected to the top of the first connecting plate 302. The outer sides of the threaded rods 9 are slidably connected to the sleeves 10. The threaded rods 9 are all located inside the sleeves 10. The sleeves 10 are fixedly connected to the second connecting plate 51. The first elastic member 11 is fixedly connected between the sleeves 10 and the threaded rods 9. The first elastic member 11 is configured as a coil spring. An adjusting nut 24 is threadedly connected to the threaded rod 9. The adjusting nut 24 is located on the lower side of the sleeve 10. When the adjusting nut 24 is rotated, the adjusting nut 24 moves up and down along the threaded rod 9 and then drives the second connecting plate 51 and the inner cylinder 5 to rise and fall through the sleeve 10. The height difference between the first connecting plate 302 and the second connecting plate 51 is adjusted by adjusting the fixing nut on the threaded rod 9, so that the gap between the conical grinding disc 7 and the inner cylinder 5 is the specified required size. When the conical grinding disc 7 grinds harder materials such as nuts and screws, the harder materials will push the inner cylinder 5 upward when they are close to the gap between the conical grinding disc 7 and the inner cylinder 5, and the first elastic member 11 will be compressed, and the gap between the conical grinding disc 7 and the inner cylinder 5 will be enlarged, so that the harder materials can pass through the gap and enter the cylinder 3. After the harder materials enter the cylinder 3, the first elastic member 11 returns to its original state to reset the inner cylinder 5 to prevent the harder materials from damaging the conical grinding disc 7, thereby protecting the cone mill and extending the service life of the cone mill.

[0028] like Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the filtering mechanism includes a collecting frame 12, a sliding frame 13, a filter plate 14 and a magnetic suction component. The bottom of the lower hopper 8 is provided with a collecting frame 12 fixedly connected to the bracket 1, the collecting frame 12 is communicated with the lower hopper 8, and a discharge port 121 is opened at the bottom of the collecting frame 12, and the discharge port 121 is circularly arranged. The collecting frame 12 is slidably connected to the sliding frame 13 inside, and the top, bottom and front side of the sliding frame 13 are all open. A sliding hole for the sliding frame 13 to slide out is opened on the right side of the collecting frame 12, and the filter plate 14 is connected to the middle of the sliding frame 13. The middle of the sliding frame 13 is connected to a magnetic suction component for adsorbing iron elements in lithium battery materials. When filtering lithium battery materials, the lithium battery materials fall from the cylinder 3 into the collection frame 12, and then the aluminum battery materials are filtered through the filter plate 14. The harder materials will remain on the filter plate 14. When it is necessary to clean the harder materials on the filter plate 14, the sliding frame 13 is pulled to the right to move it out of the collection frame 12, and then the filter plate 14 is cleaned to sweep the harder materials out from the front side of the sliding frame 13. After cleaning, the filter plate 14 is moved to the left and reset. The lithium battery materials can be filtered and the filtering and recovery efficiency of the lithium battery materials is improved.

[0029] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the magnetic attraction component includes a card plate 17, a sliding rod 18 and a magnetic strip 19. The card plate 17 is clamped on the rear side of the sliding frame 13, and eleven sliding rods 18 are fixedly connected to the front side of the card plate 17. The sliding rods 18 are made of plastic and can protect the magnetic strips 19. The sliding rods 18 all pass through the rear side of the sliding frame 13, and the sliding rods 18 and the sliding frame 13 are both slidably connected. The front sides of the sliding rods 18 are all open, and the inside of the sliding rods 18 are clamped and connected with magnetic strips 19. When it is necessary to clean the iron elements adsorbed by the magnetic suction component, first move the sliding frame 13 to the right out of the collection frame 12, and then move the card plate 17 backward to make the sliding rod 18 slide backward. In the process of sliding the sliding rod 18 backward, the sliding frame 13 scrapes off the iron elements adsorbed on the outside of the sliding rod 18. When the magnetic strip 19 needs to be replaced, the magnetic strip 19 is pulled out of the sliding frame 13, and then the new magnetic strip 19 is placed in the sliding frame 13. The magnetic suction component can filter the iron elements, thereby further improving the recovery efficiency of lithium battery materials.

[0030] like Figure 2 and Figure 3As shown, it also includes a jacket 24, the outer wall of the inner cylinder is provided with the jacket 24, and through holes for the water supply pipe 23 to pass through are opened on the left and right sides of the outer cylinder, and the jacket 24 is connected to the water source through the water pipe 23 passing through the outer cylinder 301. When the cone mill crushes and pulverizes the lithium battery material, an external water tank with a water pump is connected to the water discharge end of the water pump with the left water pipe 23, and water is injected into the left water pipe 23 to fill the inside of the jacket 24 with water, and then the right water pipe 23 is connected to the water inlet end of the water pump, so that the inner cylinder 5 can be subjected to water cooling circulation and temperature reduction treatment, reduce the heat generated by the conical grinding disc 7 when crushing the lithium battery material, prevent high temperature from aggravating the thermal expansion and contraction of metal parts to cause additional noise and vibration, and at the same time avoid the function decline of the cone mill caused by high temperature.

[0031] like Figure 5 and Figure 8 As shown, the filtering mechanism also includes a second motor 20, a cam 21 and a second elastic member 22. The second motor 20 is installed on the left side of the collection frame 12. The cam 21 is fixedly connected to the output shaft of the second motor 20. Three second elastic members 22 are fixedly connected to the left and right sides of the top of the filter plate 14. The second elastic member 22 is set as a spiral spring. The filter plate 14 is fixedly connected to the sliding frame 13 through the filter plate 14, and the cam 21 contacts the bottom of the filter plate 14. When the filtering mechanism filters the lithium battery material, the cam 21 is driven to rotate by the second motor 20. When the raised part of the cam 21 contacts the bottom of the filter plate 14, the filter plate 14 moves upward to squeeze the second elastic member 22. When the raised part of the cam 21 is away from the bottom of the filter plate 14, the second elastic member 22 returns to its original state to reset the filter plate 14 downward, thereby enabling the filter plate 14 to shake up and down, so that the lithium battery material on the filter plate 14 is dispersed, and the lithium battery material on the filter plate 14 is prevented from accumulating too much and affecting the recovery efficiency.

[0032] like Figure 6 and Figure 7 As shown, the filtering mechanism further includes a rotating disk 15 and a protrusion 16. The rotating disk 15 is rotatably connected to the left side of the sliding frame 13, and the protrusion 16 is fixedly connected to the circumference of the rotating disk 15. A limiting groove that cooperates with the rotating disk 15 and the protrusion 16 is provided at the center of the right side of the collecting frame 12. When the sliding frame 13 moves rightward out of the collecting frame 12, the rotating disk 15 contacts the inner wall of the collecting frame 12, and then the sliding frame 13 is rotated to be perpendicular to the ground, so that the harder material can fall off the filter plate 14, which is convenient for cleaning the filter plate 14. The protrusion 16 can limit the rotation angle of the sliding frame 13 to ensure that the sliding frame 13 can be reset normally.

[0033] like Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, a handle is also included, and a handle is installed on the right side of the sliding frame 13. When the sliding frame 13 is moved, the left and right movement of the sliding frame 13 is controlled by the handle, which can make it easier to move the sliding frame 13 and prevent the sliding frame 13 from slipping when being pulled.
