Description

Technical Field

[0001] The utility model relates to the technical field of boron carbide powder production, and particularly relates to a device for producing boron carbide powder. Background Art

[0002] Boron carbide, also known as black diamond, is an inorganic substance with the chemical formula B4C. It is one of the three hardest known materials (after diamond and cubic boron nitride). Due to its low density, high strength, high temperature stability, and good chemical stability, compared with diamond and cubic boron nitride, boron carbide is easier to manufacture and has a lower cost, so it is more widely used and can replace expensive diamond in some places. It is commonly used in grinding, lapping, drilling, etc. However, in the production process of boron carbide powder, traditional methods often have problems such as low efficiency and difficulty in stable quality control, and cannot meet the high-quality requirements of modern industry for boron carbide powder. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the existing technology, and provide a device for producing boron carbide powder. By using the method of collaborative production of a sand mill and a hydrocyclone, it can divide and grind boron carbide particles to ensure the production quality and production efficiency of boron carbide powder.

[0004] The technical solution adopted by the utility model is a device for producing boron carbide powder, including a device body. The device body includes a feed pipe, the feed pipe is connected to a feed pump, the feed pump is connected to a hydrocyclone feed pipe, the hydrocyclone feed pipe is connected to a hydrocyclone, the hydrocyclone is connected to a B tank through a hydrocyclone support. On the top of the B tank, there is a first support rod, the first support rod is connected to a B tank motor, the B tank motor is connected to a first stirring rod, the first stirring rod is connected to a first stirring blade. On one side of the bottom of the B tank, there is a B tank discharge pipe, the B tank discharge pipe is connected to a pump, the pump is connected to a sand mill feed pipe, the sand mill feed pipe is connected to a sand mill main body. On the top of the sand mill main body, there are an alarm and a cold air inlet pipe. Inside the sand mill main body, there is a temperature monitor. On the rear wall of the sand mill main body, there are heat dissipation holes, and the peripheral walls of the heat dissipation holes are connected to a heat dissipation chamber. On the wall of the heat dissipation chamber, there is a heat dissipation fan. Above the other side of the sand mill main body, there is a sand mill discharge pipe, and the sand mill discharge pipe is connected to an A tank.

[0005] On the top of the A tank, there is a second support rod, the second support rod is connected to an A tank motor, the A tank motor is connected to a second stirring rod, the second stirring rod is connected to a second stirring blade. On one side of the bottom of the A tank, there is an A tank discharge pipe. On the wall of the A tank, there is an A tank observation port. The top of the A tank is connected to the hydrocyclone through an overflow pipe (26).

[0006] On one side of the main body of the sand mill, there are support columns, which are connected to the sand mill motor, and the sand mill motor is a 30KW motor.

[0007] On the wall of the B tank, there is an observation port for the B tank.

[0008] The bottom discharge port of the cyclone is located inside the feed port at the top of the B tank.

[0009] The beneficial effects of the present utility model: In the production process of boron carbide powder, a cyclone, a B tank and a sand mill are added. The cyclone can divide and shunt boron carbide particles. The qualified boron carbide particles meeting the process requirements directly overflow into the A tank, and the unqualified boron carbide particles enter the B tank for storage, and then are ground by the sand mill to be qualified and then returned to the A tank, ensuring the quality of the boron carbide particles used in production.

[0010] The sand mill motor on the sand mill is a 30KW motor. It is more appropriate to control the current of the main body of the sand mill at 45A - 50A and the temperature at about 40°C. The normal heat dissipation of the main body of the sand mill can be dissipated to the heat dissipation chamber through the heat dissipation holes and then discharged by the heat dissipation fan. However, when the temperature monitor detects that the temperature of the main body of the sand mill is over-temperature, it will trigger an alarm, reminding the production personnel to turn on the cold air and make the cold air enter the main body of the sand mill from the cold air inlet pipe to cool down the temperature.
