Description

Technical Field

[0001] The present invention relates to the technical field of grinding equipment, and more specifically, to a lithium battery grinding equipment. Background Art

[0002] With the improvement of the quality and reputation of new energy vehicles, more and more people choose to buy new energy vehicles, resulting in an explosive growth in the sales of new energy vehicles. However, the energy power batteries of new energy vehicles have a lifespan, which means that the recycling and reuse of power batteries will also have an explosive growth in the next few years. Faced with such a huge amount of power battery recycling and processing, a very perfect recycling production line is needed.

[0003] At present, the mainstream lithium battery recycling production line process is to crush and calcine the battery cell to remove the electrolyte and diaphragm, separate the shell, screen the black powder, leave the copper and aluminum pole pieces, and then grind the copper and aluminum pole pieces into particles of appropriate size, and separate the copper and aluminum particles from the copper and aluminum mixture by specific gravity sorting. In this process, the equipment for grinding copper and aluminum pole pieces is one of the key equipment of the production line. The quality of grinding directly affects the purity of the subsequent copper and aluminum particles. The requirement for the grinding equipment is to keep the particle size of copper and aluminum ground as consistent as possible. However, there is no grinding equipment specifically for the lithium battery industry in the existing market. For traditional grinding equipment, most of them cannot adjust the size of the grinding gap. Generally, the grinding size is adjusted by controlling the speed. It is greatly affected by the feed amount, and there is always a large amount of over-grinding, which wastes work. As a high-power device, its grinding efficiency is low and the power consumption is large, resulting in high cost of use. In addition, during the working process of traditional grinding equipment, when copper and aluminum are over-ground into ultra-fine powder, it will lead to the inability to separate, and there is a risk of explosion when aluminum powder particles are less than 70 microns, which seriously affects the safety of grinding.

[0004] Therefore, how to provide a lithium battery grinding device that can adjust the grinding gap to avoid repeated excessive grinding of materials into ultra-fine powder, can push the material out of the equipment quickly to avoid material accumulation, and reduce energy consumption while improving work efficiency has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0068] The technical solution of the present invention is specifically described below in conjunction with specific embodiments:

[0069] Specifically, in a specific embodiment of the present invention, the lithium battery grinding equipment further includes: a negative pressure fan or a vacuum pump connected to the discharge pipe 2-7.

[0070] In traditional grinding equipment, when the material is over-grinded, the material is easily accumulated when discharged from the collection chamber, causing blockage, so it is urgent to optimize the material collection chamber. Figure 4 As shown, in an embodiment of the present invention, the spiral collecting chamber 2 is used to collect the ground material and promote the rapid discharge of the material; wherein the spiral collecting chamber 2 is composed of the circular ring outer plate 2-1, the first supporting flange 2-2, the circular ring inner plate 2-3, the second supporting flange 2-4, the reinforcing rib plate 2-5, the spiral guide plate 2-6 and the discharge pipe 2-7, the steel plate is rolled into the circular ring outer plate 2-1 and the circular ring inner plate 2-3, the first supporting flange 2-2 is arranged at the top of the circular ring outer plate 2-1, which is used to connect the grinding chamber 3, and the second supporting flange 2-4 is installed at the top of the circular ring inner plate 2-3, which is used to connect the spindle assembly 6; the circular The outer ring plate 2-1 and the inner ring plate 2-3 are coaxially arranged, and the spiral guide plate 2-6 is arranged between the outer ring plate 2-1 and the inner ring plate 2-3.

Compared with the horizontal guide plate, the resistance to the advancement of the material is smaller, and under the dual effects of the clockwise cyclonic airflow and the negative pressure suction generated by the rotation of the cutter disc rotor assembly 7, the material can be pushed to leave the equipment quickly, thereby avoiding material accumulation, improving the passing efficiency, increasing the production capacity and reducing the energy consumption.

[0071] Specifically, in a specific embodiment of the present invention, the grinding chamber 3 is a vertical truncated cone structure.

[0073] like Figure 5 , 67, the grinding chamber 3 is used for cutting and grinding the material input from the feed hopper 5; in the embodiment of the present invention, the grinding chamber 3 adopts a vertical truncated cone structure, and its structure is composed of the upper end flange 3-1, the lower end flange 3-2, the conical side plate 3-3, the upper limit flange 3-4, the lower limit flange 3-5, the fastening mechanism 3-6 and the limit mechanism 3-7; wherein, the conical side plate 3-3 is installed between the horizontally arranged upper end flange 3-1 and the lower end flange 3-2, and the upper and lower ends of several fixed knife blocks 4 are respectively fixed by bolts by the lower end flange 3-2 and the lower limit flange 3-5, and the fixed knife blocks 4 are evenly spaced from each other, so that the fixed knife blocks on the fixed knife blocks are fixed in pairs. A uniform gap is reserved between the knives; and, in the scheme involved in the embodiment of the present invention, in the grinding chamber 3, the cutter disc rotor assembly 7 is installed in the hollow frustum formed by multiple fixed cutter blocks 4. The cutter disc rotor assembly 7 and the fixed cutter block 4 are both coaxial cones, which are no longer coaxial circular structures compared with the prior art. The adjustable grinding gap function can be achieved by lifting or lowering the fixed cutter vertebral body up and down. When the material in the chamber reaches the size of the gap of the fixed cutter block 4, it can quickly leave the grinding area from the gap of the fixed cutter block 4 or the gap between the fixed cutter block 4 and the cutter disc rotor under the action of its own weight and negative pressure suction, avoiding repeated over-grinding, effectively preventing copper and aluminum materials from being ground into ultra-fine powder, eliminating safety hazards, and at the same time reducing power consumption.

The installation position of the grinding chamber 3 on the spiral collecting chamber 2 can be raised or lowered by rotating the screw, and the fastening mechanism 3-6 is connected to the lower end flange 3-2 at one end and connected to the first supporting flange 2-2 at the other end. After the limiting mechanism 3-7 determines the installation position of the grinding chamber 3 in the vertical direction, the fastening mechanism 3-6 is used to fasten the grinding chamber 3 and the spiral collecting chamber 2. Through the mutual cooperation of the two, the grinding gap can be adjusted.

[0078] Because traditional grinding equipment is noisy and has no shock-absorbing or sound-isolating design, long-term use in factories will have a significant impact on workshop workers. Figure 7 As shown, in the embodiment of the present invention, the grinding chamber 3 adopts a cavity design, the hollow chamber 10 is reserved between the conical side plate 3-3 and the fixed knife block 4, and the middle cavity is filled with sound insulation cotton 11, which plays the role of filling support and sound insulation, can greatly reduce the equipment noise, and solve the problem of high noise in traditional grinding equipment; and in order to solve the problem that the fitting surface of the fixed knife block 4 needs to be processed as a whole, the processing difficulty is large, the structure is complex, and it is easy to deform, in the embodiment of the present invention, only the upper and lower ends of the flanges 17 that fit the fixed knife block 4, that is, the lower limit flange 3-5 and the lower end flange 3-2 are finely processed to support and fit the fixed knife block 4, so that the structure of the grinding chamber 3 is a general plate with upper and lower fine-processed flanges 17 welded to a rolled cone, the processing difficulty is greatly reduced, and at the same time, it can avoid the uneven installation of the fixed knife due to the non-circular finishing error of the inner wall of the cone, and the uneven gap with the moving knife, and the uneven distribution of the grinding particle size. Good assembly progress can also better extend the service life of the rotor assembly and the fixed knife block 4.

[0096] As described above, an embodiment of the present invention involves a lithium battery grinding device that can solve the problems that the grinding equipment traditionally used in the lithium battery industry cannot adjust the size of the grinding gap, is greatly affected by the feed amount, always has a large amount of over-grinding, wastes work, has low grinding efficiency, and the material discharge is very easy to accumulate.In the lithium battery grinding equipment disclosed in the present invention, its main structure is composed of the grinding frame 1, the spiral collection chamber 2, the grinding chamber 3, the fixed knife block 4, the feed hopper 5, the spindle assembly 6, the cutter disc rotor assembly 7, the motor assembly 8 and the transmission assembly 9; wherein the feed hopper 5, the grinding chamber 3 and the spiral collection chamber 2 are arranged on one side of the grinding frame 1 from top to bottom, the feed hopper 5 is used to input the grinding material, and the material falls into the grinding chamber 3 from the feed hopper 5, the cutter disc rotor assembly 7 is arranged in the grinding chamber 3, and cooperates with the fixed knife block 4 installed in the grinding chamber 3 to cut and grind the material; and for the input of cutting power, the motor assembly 8 is installed on the other side of the grinding frame 1, and the motor assembly 8 The output end is connected to the transmission assembly 9, which can transmit the rotational power provided by the motor assembly 8 to the spindle assembly 6, so that the spindle assembly 6 drives the cutter disc rotor assembly 7 to rotate along a fixed axis, and drives the rotor to rotate for grinding operation; when the material reaches the preset particle size, the material falls into the spiral collection chamber 2, and under the action of the cyclonic airflow generated by the rotation of the cutter disc rotor assembly 7 and the negative pressure suction at the rear end, a high-speed spiral airflow is formed in the spiral collection chamber 2, which pushes the material to be quickly discharged from the collection chamber; and, since the fixed knife block 4 is enclosed in the grinding chamber 3 to form a hollow frustum, and the cutter disc rotor assembly 7 for grinding and cutting is also a cone arranged in the hollow frustum, the two are coaxial vertebral bodies, so by lifting or lowering the fixed knife block 4, the material can be quickly discharged from the collection chamber. The vertebral body of the fixed blade block 4 can adjust the grinding gap to meet the grinding operation of materials with particles of different sizes; secondly, for the actual grinding process of the lithium battery grinding equipment, after the material enters the grinding chamber 3 from the feed hopper 5, it is quickly broken up by the dispersion disk 7-2 on the top of the cutter disc rotor assembly 7, evenly dispersed to the four walls of the grinding chamber 3, and enters the grinding area between the cutter disc rotor assembly 7 and the fixed blade block 4. Subsequently, the cutter disc rotor assembly 7 rotates at a high speed to drive the air in the grinding chamber 3 to rotate together and form a high-speed airflow. The material is accelerated to a linear speed as high as the airflow and the outer ring of the cutter disc rotor assembly 7 under the push of the high-speed airflow and the high-speed rotating cutter disc rotor. Under the action of the cutter disc rotor assembly 7 and the fixed blade block 4, the material is sheared, impacted, crushed and ground. Under the action of external force, the movement direction and speed of the material change instantly, and the material particles also collide with each other, completing a relatively ideal crushing in the high-speed airflow. When the ground material reaches the gap size of the fixed knife block 4, it can quickly leave the grinding area from the fixed knife gap or the gap between the fixed knife and the moving knife under the action of its own weight and negative pressure suction (rear end negative pressure conveying) and enter the spiral collection chamber 2. On the spiral downward spiral guide plate 2-6 of the spiral collection chamber 2, it is affected by the downward component of its own weight. Compared with the horizontal guide plate, the material has less resistance to advancement. Combined with the dual action of the cyclone airflow and negative pressure suction generated by the rotation of the cutter disc rotor assembly 7, the high-speed spiral airflow generated can push the material to quickly leave the equipment from the discharge pipe 2-7, thereby completing the material grinding operation.It can be seen that compared with the prior art, the technical solution involved in the present invention can adjust the grinding gap to avoid repeated excessive grinding of materials into ultra-fine powder, can push materials to leave the equipment quickly to avoid material accumulation, and reduce energy consumption while improving work efficiency.
