Working principle: using this graphite powder processing equipment, the specific operations are as follows:

Step 1: First pour graphite into the crushing mechanism, improve the crushing efficiency by double-opening crushing settings, and use the second drive motor to drive the worm to rotate. When rotating, it drives the worm gears on both sides to rotate synchronously, and then drives the connected first The crushing shaft rotates so that the first crushing shaft on the left and right side cooperates to complete the crushing operation, and at the same time, the first crushing shaft on the left side drives the second crushing shaft on the right side connected to the driven wheel through the belt to rotate through the driving wheel connected, so that it is connected with the The turning direction of the first crushing shaft on the right is opposite, and so on, the second crushing shaft on the left is synchronously driven to rotate, so that it is opposite to the turning direction of the first crushing shaft on the left, thereby speeding up the crushing processing efficiency;

Step 2: The crushed graphite powder enters the dry grinding mechanism for processing, first falls into the grinding box, and the roller scraper is driven to rotate synchronously through the connection between the worm and the linkage shaft, and then grinds the incoming graphite once and scraping, and after completion, it is discharged in sections through the inner and outer discharge ports opened at the bottom of the grinding box, and finally enters the drying box for high-temperature drying. Internal and external cutting, so that the graphite material is separated, thereby accelerating the drying rate of moisture in the graphite material;

Step 3: The dried graphite material is discharged through the outlet of the drying box, enters the material receiving tray, and is placed between two adjacent pushing blocks for external cooling, and at the same time cooperates with the cylinder outside the drying box The fan is air-dried. After the air-drying is completed, by starting the movement of the slider on the electric slide rail, the pushing block connected to the slider is driven to rotate, thereby pushing the graphite material to move. At the same time, the movement of the pushing block will also release the external distribution box. The plugging of the upper discharge port allows the pushed material to enter the spliced bottle mouth box through the discharge port and the sliding material ring, and fall into the spray well shaft. The graphite material falling in the spray well shaft is screened through vibration. The screened graphite powder falls on the second filter disc, and then the windmill plate is driven by the first drive motor to rotate, and the second filter disc on the windmill plate is replaced, and when a second filter disc leaves, the wellbore and protection When there is no second filter disc in the hollow space of the cylinder, the centrifugal fan will be activated synchronously, and then agitated by strong winds, blowing up the graphite material on the first filter disc, so that the large particles that cannot fall will be sprayed out from the well. Then the graphite powder will dissipate in the spliced bottle mouth box, and the metal impurities will be adsorbed by the magnetic suction frame surrounding the mouth of the spray well, and the graphite powder can be turned into a fugitive by this spray well method , and capture the metal substances in the fugitive body for adsorption. Compared with the current fixed magnetic adsorption, the adsorption effect is stronger, and the overall flow adsorption is stronger, and the large particles of graphite powder that spew out will also fall into the chassis. By using The first drive motor drives the driving power of the sleeve rod, and synchronously drives the gear to rotate, so that the gear drives the inner gear ring and the chassis connected to the inner gear ring to rotate synchronously, and cooperates with the grinding rod and scraping rod inside the external distribution box for secondary grinding processing, and follow the rotation of the windmill plate for staged grinding, and staged discharge through the discharge valve at the bottom, pick up the graphite powder from the discharge connection box, and discharge it to the external receiving material through the feeding pump collection in box;

Step 4: Among them, after the second filter disc is brought out, it will first pass through the right collection box, use the electric push rod and the flush enclosure to push the graphite powder accumulated above the second filter disc into the collection box for collection, and then pass through the left side. The side collection box uses a brush for scraping treatment, and the graphite powder collected twice will enter the corresponding collection box, and the sliding box connected to the collection box is used for magnetic suction treatment of sliding down, and the fine graphite powder Adsorption of metal impurities is carried out, and the graphite powder discharged at the same time will be collected in different material receiving boxes, which is convenient for distinguishing the collected graphite powder;

Step 5: Among them, the metal impurities adsorbed by the magnetic suction frame are recovered, and the electric telescopic rod is used to drive the magnetic suction frame to rise, so as to rise to the upper part of the splicing bottle mouth box, and at the same time, the lower side will also be blocked to connect with the splicing bottle mouth The box also forms a slope, and then the power supply of the magnetic rack is disconnected, and the adsorbed metal impurities fall into the metal tray through the slope for collection and utilization.

The invention provides a processing equipment for graphite powder, a negative electrode material of a lithium battery. Has the following beneficial effects:

1. The present invention collects graphite by using the rotation of the windmill plate in the magnetic suction filter mechanism, and at the same time triggers the blowing of the centrifugal fan in the replacement stage, so as to perform eruptive dissipation treatment on the graphite powder, and then cooperate with the up and down magnetic suction frame, and grind Rods and scraping rods are used to absorb metal impurities and regrind. Through this spray well method, the graphite powder can be turned into fugitives, and the metal substances in the fugitives can be captured for adsorption. The adsorption effect is compared with the current fixed magnetic suction. , the overall flow adsorption is stronger, and the adsorption effect of metal impurities is better, which effectively improves the processing capacity of graphite powder processing equipment to remove metal impurities in graphite powder.

2. The present invention improves the crushing efficiency through double-opening crushing settings. The whole uses the second drive motor to drive the worm to rotate. When rotating, it drives the worm wheels on both sides to rotate synchronously, and then drives the first crushing shaft connected to it to rotate, so that the left and right sides of the first crushing shaft A crushing shaft cooperates to complete the crushing operation, and at the same time, the first crushing shaft on the left uses the connected drive wheel to drive the second crushing shaft on the right connected to the driven wheel through a belt to rotate, making it turn in the opposite direction to the first crushing shaft on the right , and so on, synchronously drive the second grinding shaft on the left to rotate, so that it is opposite to the rotation of the first grinding shaft on the left, thereby speeding up the grinding processing efficiency, and cooperate with the drying and grinding mechanism to grind and dry the grinding material synchronously, improving the overall processing efficiency.

3. In the present invention, the electric telescopic rod is used to drive the magnetic rack to rise, so as to rise to the upper part of the splicing bottle mouth box, and at the same time, the lower part will also be blocked, forming an inclined plane like the splicing bottle mouth box, and then disconnecting the power supply of the magnetic suction rack. The adsorbed metal impurities fall into the metal tray through the inclined plane for accumulation, which can be more effectively changed alternately between the magnetic attraction and degaussing states, and it is easier to collect and utilize metal impurities.
