Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of metal powder preparation equipment, and particularly relates to a metal powder preparation tank body internal spraying and condensing system. BACKGROUND

[0002] Metal powder, particularly superfine metal powder material, has been widely applied in the fields of catalysis, optics, medicine, electronics, information storage and the like due to its special properties, and the preparation, structure, performance and application research of the metal powder have become a hot spot of material science research and industrialization in recent years.

[0003] At present, the preparation approaches of metal powder material mainly include chemical method and physical method. In the physical method, no chemical reaction exists, no polluting gas and waste liquid are generated, and the physical method is environmentally friendly. In particular, the hot melting gas atomization and plasma evaporation condensation for preparing superfine metal powder are increasingly widely used. The particle size of the superfine metal powder is relatively uniform, the purity is high, and the superfine metal powder is suitable for metals with high melting point and boiling point. The preparation process of the superfine metal powder needs to be carried out in a vacuum or inert gas atmosphere such as argon gas and helium gas, and therefore the sealing requirement of the equipment is high. In addition, the gas pressure, temperature and airflow dynamics in the condensing and powdering stage have different degrees of influence on the particle size and morphology of the prepared powder. Moreover, the powder particles are more likely to adhere to the inner wall of the equipment due to the small particle size, which affects the collection. When the equipment is cleaned, the dust needs to be prevented from leaking, the space of the equipment is limited, manual intervention not only causes safety hazards to the operators, but also pollutes the powder and brings external interference risks to the equipment.

[0004] In the traditional metal powder preparation tank, the furnace wall jacket water or gas cooling is usually used for condensing and temperature control. However, the cooling efficiency is low due to the influence of the heat exchange area, the temperature gradient from the center to the furnace wall is large, and the particle size distribution of the powder particles is not easy to control. In addition, the powder particles are easy to adhere to the wall. There are also devices for arranging multiple point gas flow spraying on the periphery of the metal powder preparation tank to carry out condensing. However, the number of holes and joints of the equipment is large, the gas distribution pipeline of the metal powder preparation tank is complicated, the leakage risk of the equipment is increased, and if the condensing fixed pipe of the metal powder preparation tank is extended from the tank body, the internal space arrangement of the equipment is affected. If the condensing fixed pipe is not extended from the tank body, the blowing and sweeping distance of the inner wall of the pipe body is increased, and the capacity is insufficient. With the increase of the size of the equipment, the defects are more serious. Therefore, the application provides a metal powder preparation tank body internal spraying and condensing system.
