TECHNICAL FIELD

[0001] The utility model relates to a crushing equipment technical field especially relates to a lithium iron phosphate processing sanding device. BACKGROUND

[0002] Lithium iron phosphate is a lithium ion battery electrode material, and its chemical formula is LiFePO4. It is mainly used in various lithium ion batteries. Lithium iron phosphate is the safest lithium ion battery cathode material and does not contain any heavy metal elements harmful to the human body. Because of its good performance, lithium iron phosphate is widely used in new energy batteries. Before processing lithium iron phosphate, it needs to be crushed. A lithium iron phosphate processing sanding device is used during crushing. However, the traditional lithium iron phosphate processing sanding device crushes the material by using a crushing roller, which leads to incomplete crushing of the lithium iron phosphate raw material, and the large and small particles are mixed together, affecting the quality of the lithium iron phosphate raw material crushing and resulting in poor crushing effect. SUMMARY

[0003] The utility model provides a lithium iron phosphate processing sanding device to solve the problems in the above background.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A lithium iron phosphate processing sanding device, comprising an outer cylinder and a grinding cylinder, the inner bottom of the outer cylinder is fixed with a grinding cylinder, the bottom of the grinding cylinder is fixed with a filter screen, the top of the outer cylinder is fixed with a servo motor, the bottom of the transmission shaft of the output end of the servo motor is rotatably connected with a connecting rod, the outer wall of the connecting rod is fixed below with an upper blade, the bottom of the connecting rod is fixed with a grinding disc, the bottom of the grinding disc is fixed with a scraper, the right side of the inside of the outer cylinder is fixed with an outer servo motor, the inside of the outer cylinder is embedded with an inner disc plate, the upper surface of the inner disc plate is vertically fixed with a stand column, and the inside of the inner disc plate is fixed below with a lower blade.

[0006] Preferably, the bottom of the scraper below the grinding disc is tightly attached to the upper surface of the filter screen, and the rotating area of the scraper is consistent with the cross-sectional area of the filter screen.

[0007] Preferably, the grinding disc is arranged just above the inside of the grinding cylinder, and the outer wall of the grinding disc is circularly and equidistantly provided with 8-20 feeding grooves.

[0008] Preferably, the outer servo motor is counterclockwise rotationally connected between the gear disc and the inner disc plate, and the stand column is circularly arranged around the middle part of the upper surface of the inner disc plate.

[0009] Preferably, the upper blade and the lower blade are arranged in a circular ring around the middle part of the connecting rod and the inner disc plate respectively, and the bottom end of the upper blade is tightly attached to the upper surface of the lower blade.

[0010] Preferably, the servo motor drives the upper blade and the grinding disc to rotate in the clockwise direction through the connecting rod, and the connecting rod is vertically arranged through the middle part of the inner disc plate.

[0011] 1. After the lithium iron phosphate falls on the inner disc plate rotating in the counterclockwise direction along the feeding hopper, the lithium iron phosphate falls along the surface of the inner disc plate due to the gravity, and the rotating column on the inner disc plate collides with the falling lithium iron phosphate to disperse the lithium iron phosphate. When the dispersed lithium iron phosphate falls from the middle part of the inner disc plate, the upper blade and the lower blade rotating in the reverse direction shear and crush the falling lithium iron phosphate to realize the pre-crushing of the lithium iron phosphate, so that the larger lithium iron phosphate particles are prevented from being stuck between the grinding cylinder and the grinding disc. Then, the crushed lithium iron phosphate enters between the grinding cylinder and the grinding disc for grinding, so that the size of the ground lithium iron phosphate particles is more uniform, and the grinding effect is better.

[0012] 2. After the lithium iron phosphate enters between the grinding cylinder and the grinding disc for grinding, the powdered lithium iron phosphate slides to the middle part of the grinding cylinder, and then falls through the filter screen in the middle part of the grinding cylinder. At this time, since the servo motor drives the grinding disc to rotate through the connecting rod, the scraper at the bottom of the grinding disc continuously scrapes the upper surface of the filter screen to push the lithium iron phosphate to move on the upper surface of the filter screen, so that the filter screen is prevented from being blocked due to the accumulation of a large amount of lithium iron phosphate on the upper surface of the filter screen, and the speed of the lithium iron phosphate passing through the filter screen is improved, so that the use is more convenient.

[0020] The bottom of scraper 204 below grinding disc 203 is tightly attached to the upper surface of filter screen 102, and the rotation area of scraper 204 is consistent with the cross-sectional area of filter screen 102;

[0021] After grinding, the powdered lithium iron phosphate slides to the middle of the grinding cylinder 101, and then falls through the filter screen 102 in the middle of the grinding cylinder 101. At this time, since the servo motor 2 drives the grinding disc 203 to rotate through the connecting rod 201, the scraper 204 at the bottom of the grinding disc 203 continuously scrapes the upper surface of the filter screen 102 while rotating, pushing the lithium iron phosphate on the upper surface of the filter screen 102 to move, avoiding the accumulation of a large amount of lithium iron phosphate on the upper surface of the filter screen 102, causing the filter screen to be blocked, and at the same time, improving the speed of lithium iron phosphate passing through the filter screen 102, making it more convenient to use;

[0022] The grinding disc 203 is arranged above the inside of the grinding cylinder 101, and the outer wall of the grinding disc 203 is circularly and equidistantly provided with 8-20 feeding grooves;
