Description

Technical Field

[0001] The invention relates to the technical field of powder processing, and in particular to a spiral powder cooling structure. Background Art

[0002] Metal powder refers to a group of metal particles with a size of less than 1mm. It includes single metal powder, alloy powder and certain refractory compound powders with metallic properties. It is the main raw material for powder metallurgy. Metal single substance is generally silvery white. When the metal is under certain conditions, it becomes black powder.

[0003] The preparation and application of metal powders have a long history. In ancient times, gold, silver, copper, bronze and some of their oxide powders were used as coatings for the coloring and decoration of pottery, jewelry and other utensils. Metal powders are loose substances, and their properties comprehensively reflect the properties of the metal itself, the properties of individual particles and the characteristics of particle groups. The properties of metal powders are generally divided into chemical properties, physical properties and process properties. Chemical properties refer to metal content and impurity content. Physical properties include the average particle size and particle size distribution of the powder, the specific surface area and true density of the powder, the shape, surface morphology and internal microstructure of the particles. The conventional process for preparing metal powders is to put the metal block mixed with water into a ball mill, rotate the ball mill, and use the spherical grinding block to impact and crush the metal block, and finally obtain a fluid mixed with metal powder and water.

[0004] The production of metal powder generally includes the steps of smelting, atomization and cooling. The metal is atomized into droplets or particles through smelting, and then cooled. In the prior art, metal powder needs to be cooled during processing, but many small factories cool the powder by wrapping a water cooling pipe around the container, or directly cooling it manually, which is troublesome and inefficient. Summary of the invention

[0005] The main purpose of the present invention is to provide a spiral powder cooling structure to solve the problems raised in the background technology.

[0008] To further describe the present invention, a pipe cover is also provided at the top of the spiral powder tube.

[0009] To further describe the present invention, a water inlet hose is provided on one side of the cooling water tank, and one end of the water inlet hose extends to the outside of the shell.

[0011] To further describe the present invention, the rotating drum is provided with a connecting shaft, and the connecting shaft is welded to the output end of the motor.

[0012] To further describe the present invention, the shell is square.

[0013] To further describe the present invention, the motor used is model JZQ200.

[0014] Compared with the prior art, the advantages of the present invention are:

In order to facilitate feeding, a pipe cover 301 is also provided at the top of the spiral powder tube 3. In order to facilitate water injection, a water inlet hose 4 is provided on one side of the cooling water tank 6, and one end of the water inlet hose 4 extends to the outside of the housing 10. The rotating drum 15 is provided with a connecting shaft 18, and the connecting shaft 18 is welded to the output end of the motor 9.
