Description

Technical Field

[0001] The utility model relates to the technical field of drawing graphite emulsion processing, in particular to a special ultrafine powder feeding mechanism for drawing graphite emulsion. Background Art

[0002] The special ultrafine powder feeding mechanism for drawing graphite emulsion is a device used to convey and supply the special ultrafine powder for drawing graphite emulsion. By using the special ultrafine powder feeding mechanism for drawing graphite emulsion, the special ultrafine powder for drawing graphite emulsion can be accurately supplied to ensure the stability and consistency in the production process.

[0003] An automated graphite feeding device is disclosed in a Chinese utility model patent with announcement number CN219291347U. The device uses a power motor to drive a stirring blade to rotate to avoid blockage during graphite powder feeding. The feeding screw feeds the graphite powder out. During the feeding process, the scraper of the scraper fits the spiral rod. After the spiral rod rotates for a stroke, the reset spring elastically supports the knife holder to achieve movement reset. The scraper scrapes off the dust material on the spiral rod to avoid blockage.

[0004] In view of the above-mentioned technical solutions and existing technologies, the traditional ultrafine powder feeding mechanism dedicated to drawing graphite emulsion needs to pour the graphite powder into a processing cylinder when transporting graphite powder. Since graphite powder is relatively light, pouring it directly into the cylinder will cause more dust and affect the health of the workers. At the same time, directly pouring the graphite powder into the processing cylinder without processing will make the dust easily solidify, which is inconvenient to transport. For this reason, we propose an ultrafine powder feeding mechanism dedicated to drawing graphite emulsion that can reduce dust and heat the graphite powder. Utility Model Content

The fixed cover is arranged at the opening on the top of the cylinder, and a sealing ring is connected to the outside of the fixed cover. The outside of the sealing ring abuts against the inner wall of the cylinder. The two sides of the top of the fixed cover are connected to the top of the drying cylinder through a support frame.

A partition 14 is rotatably connected to the discharge port, and air inlet holes are evenly spaced on the surface of the partition 14. By using the setting of the partition 14, when the bellows 3 sucks air, the partition 14 is stuck on the protective cylinder 4, and the partition 14 is avoided as much as possible from being opened when the protective cylinder 4 rotates. Only when the auger shaft A5 drives the graphite powder to be transported to the top of the protective cylinder 4, the graphite powder is squeezed to push open the partition 14 and fall into the drying cylinder 1 for circulation. The protective cylinder 4 includes a cylinder with two ends through and a fixed cover on the top.
