Description

Technical Field

[0001] The utility model relates to the technical field of grinding devices, and more specifically, to a crushing and grinding device for the production of hard carbon anode materials. Background Art

[0002] Among various anode materials, carbon-based materials are favored due to their abundant raw materials, simple synthesis, low cost, etc. Hard carbon anode material is a kind of carbon that is difficult to graphitize even at temperatures above 2500°C, and it gets its name because of its high mechanical hardness. The morphology of hard carbon can be linear or porous. During the material synthesis process, it can usually maintain the morphology of the precursor.

[0003] When crushing hard carbon anode materials, corresponding crushing and grinding devices are usually used for auxiliary processing. The processed carbon rod raw materials are put into a crusher to be crushed into hard carbon anode material particles that meet the requirements, so as to facilitate subsequent processing and production. In traditional grinding devices, someone needs to hold the rear end of the carbon rod raw material to prevent the carbon rod from being forced in the opposite direction when the grinding component contacts the carbon rod, and it is easy to pop out of the feeding port of the grinding device. Therefore, the traditional crushing device needs to disassemble the carbon rod in advance to facilitate subsequent processing, which is rather troublesome. Summary of the Invention

The output end of the stepper motor 20 is fixedly connected to the connecting member 21;

[0028] At the lower end of the upper housing 7, a crushing box 8 is fixedly installed. In the middle of the lower side of the crushing box 8, a particle grinding plate 15 is fixedly installed. A number of particle grooves 12 are opened on the lower side of the particle grinding plate 15. At the lower side of the crushing box 8, a device base 6 is fixedly installed. At the upper end of the front side of the device base 6, a crushing motor 5 is fixedly installed. In the middle of the inner cavity of the crushing box 8, a driving shaft 14 is rotatably installed. On the outer side of the middle part of the driving shaft 14, a grinding member 13 is fixedly installed;

[0029] On the front side of the upper housing 7, a communicating pipe 2 is fixedly installed. On the front side of the communicating pipe 2, a feeding port 1 is fixedly installed. The feeding port 1 is in a horn shape, which can facilitate the operator to send the carbon rod into the communicating pipe 2;

[0030] On the lower front side of the upper housing 7, a main control board 3 is fixedly installed. Through the main control board 3, the start and stop of the crushing motor 5 and the stepper motor 20 can be controlled;

[0031] On the outer periphery of the eccentric crushing member 10 and the fixed crushing member 11, a number of separating members 23 are equidistantly fixedly installed. The separating members 23 on the outer side of the fixed crushing member 11 and the separating members 23 on the outer side of the eccentric crushing member 10 are arranged in an interlaced manner. When the carbon rod is inserted between the fixed crushing member 11 and the eccentric crushing member 10, it will be bitten and broken by the separating members 23;

[0032] In the middle of the front side of the crushing box 8, a maintenance board 4 is fixedly installed. By opening the maintenance board 4, the lower particle grinding plate 15 can be maintained and cleaned;

[0033] The output end of the crushing motor 5 is fixedly installed with a driving wheel 17. One end of the driving shaft 14 is fixedly installed with a driven wheel 18. The other end of the driving shaft 14 is fixedly installed with a stabilizing wheel 19. A transmission belt 16 is arranged between the driving wheel 17 and the driven wheel 18. On one side of the crushing box 8 where the driven wheel 18 is located, a protective side plate 9 is fixedly installed.

[0035] The working principle of the present utility model: The operator feeds the carbon rod raw material into the connecting pipe 2 through the feeding port 1. After the stepping motor 20 is started, it drives the eccentric wheel 22 to rotate through the connecting piece 21. An eccentric shaft 24 is fixedly installed in the middle of the eccentric wheel 22, and the eccentric shaft 24 will reciprocate eccentrically along with the eccentric wheel 22. When the carbon rod raw material approaches the position of the fixed crushing part 11, when the eccentric crushing part 10 and the fixed crushing part 11 move away from each other, the carbon rod raw material will enter between the eccentric crushing part 10 and the fixed crushing part 11. As the eccentric wheel 22 rotates, the eccentric crushing part 10 and the fixed crushing part 11 will clamp and grind the carbon rod raw material, and at the same time drive the carbon rod raw material to continue to fall to the bottom of the upper housing 7, avoiding the problem that the carbon rod raw material is easy to pop out of the feeding port 1 in the traditional grinding device, facilitating the subsequent grinding of the raw material, improving the grinding efficiency. The crushing motor 5 drives the driven wheel 18 to rotate through the driving wheel 17 and the transmission belt 16, and the driving shaft 14 drives the grinding part 13 to rotate at a high speed. The preliminarily crushed carbon rod raw material is crushed during the rotation of the grinding part 13. When the fragments pass through the position of the particle grinding plate 15, under the action of pressure, they pass through the particle grooves 12. The particle grooves 12 can squeeze the carbon rod debris into hard carbon negative electrode particle raw materials of appropriate size. The operator can set a storage box under the particle grinding plate 15 to recycle the raw materials.
