Description

Technical Field

[0001] This utility model relates to the field of silicon carbide micro powder production technology, and in particular to a silicon carbide micro powder purification device. Background Technology

[0002] Silicon carbide micro powder has a high thermal conductivity, which can effectively transfer heat and is widely used in electronics, aerospace and other fields. However, silicon carbide products are not perfect, especially silicon carbide lumps from Northwest Smelting, which contain some ferric oxide impurities and need to be purified to improve the quality of the material. By adding acid (sulfuric acid) or alkali (sodium hydroxide) to silicon carbide, the iron, silicon and other impurities in silicon carbide react with the acid or alkali, thereby removing the iron, silicon and other impurities, thus achieving the purpose of purifying silicon carbide. Generally, the purification reaction of silicon carbide micro powder is mostly carried out in a purification tank or purification furnace. When the reaction is carried out in the purification tank, the hydrogen gas generated by the reaction is directly discharged outdoors. There are also certain safety hazards in the purification reaction of silicon carbide micro powder. Because the reaction furnace itself does not have a cooling structure, if the large amount of heat generated by the reaction in the furnace is not discharged in time, it will cause excessive heat in the furnace, resulting in excessive internal pressure and the risk of explosion and other safety accidents, thus reducing the effectiveness of use.

[0034] Working principle: In use, the materials and additives are first fed into the assembly reaction vessel 2 through the assembly feed hopper 3. Then, the installation motor 20 is started, which drives the installation stirring bracket 21 to rotate. Next, the two electric heating plates 22 on the installation stirring bracket 21 are activated to heat and react the materials and additives. Then, the solenoid valve on the second hydrogen pipe 11 is activated, so that the hydrogen produced after the reaction passes through the first hydrogen pipe 10 and the second hydrogen pipe 11 and is discharged into the hydrogen tank 9 for storage. Then, the solenoid valve on the second hydrogen pipe 11 is opened and closed again. After storage, the electric heating plate 22 and the installation motor 20 are closed.

[0035] Then, the condenser 18 on the water inlet pipe 17 is started, followed by the liquid pump 16.

Then, the connecting push rod 26 pushes the connecting slider 25 to slide along the inside of the connecting groove, so that the connecting slider 25 drives the connecting sleeve block 24 to move along the direction on the connecting support plate 23.

[0038] The connecting sleeve 24 also drives the movable bracket 32, movable shaft 33 and movable fan blade 35 to move, so that the movable fan blade 35 can adjust up and down to blow air, so that the air can fully contact the serpentine tube 15, so that the cooling air blows and cools the surface of the storage tank 12, thereby cooling the material that accelerates the reaction inside the storage tank 12. Then the assembly valve on the assembly discharge pipe 4 is activated, so that the material is discharged into the assembly receiving box 5 for storage.
