Description

Technical Field

[0001] The invention belongs to the technical field of smelting and powder making equipment, in particular to vacuum smelting gas atomization powder making equipment. Background Art

[0002] Hydrogen storage materials, also known as hydrogen storage alloys or hydrogen storage metal compounds, are a type of material that can repeatedly and reversibly (usually more than 10,000 times) absorb and release hydrogen. When hydrogen storage materials are made into powder, vacuum melting gas atomization powder making equipment is required. Under vacuum or gas protection heating conditions, the molten metal passes through the insulated tundish crucible and the current limiting guide tube and enters the high-pressure gas atomizer. The gas jet breaks up the metal liquid and atomizes it into fine droplets, which are then deposited and cooled to solidify into micron-sized powder particles. The equipment is mainly used to prepare hydrogen storage material powders, such as magnesium-based hydrogen storage materials, rare earth hydrogen storage materials, etc. These powder materials have broad application prospects in the field of hydrogen energy, such as fuel cells, hydrogen storage and transportation, etc. However, the existing vacuum melting gas atomization powder making equipment cannot perform secondary smelting on powder particles with larger particle sizes, resulting in uneven particle size distribution and affecting processing quality.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) During use, the operator puts the hydrogen storage metal into the vacuum melting furnace for melting. The molten hydrogen storage metal liquid will enter the gas atomization chamber for spraying and atomization. After cooling, it can be made into fine powder particles. Then, the discharge valve is opened to allow the powder particles to fall onto the screen in the rotating frame for screening. The powder particles that pass the screening will accumulate on the inner bottom of the screening box, and the powder particles that fail the screening will remain on the screen. During the screening, the operator starts the servo motor to drive the threaded rod to rotate. When the threaded rod rotates, it drives the threaded sleeve to move.

[0015] (2) After the first screening, the operator closes the discharge valve and starts the drive motor. When the drive motor is running, it drives the shaft to rotate inside the bearing. When the shaft rotates, it drives the spiral feed rod to rotate. When the spiral feed rod rotates, it drives the shaft rod to rotate inside the sleeve. When the shaft rod rotates, it drives the driving sprocket to rotate along the positioning frame. When the driving sprocket rotates, it drives the driven sprocket to rotate along the rotating frame through the chain.

[0016] When the driven sprocket rotates, it drives the rotating rod to rotate inside the rotating sleeve. When the rotating rod rotates, it drives the driven bevel gear to rotate through the active bevel gear. When the driven bevel gear rotates, it drives the rotating rod to rotate inside the rotating sleeve. When the rotating rod rotates, it drives the cam to rotate intermittently and push the rotating frame to rotate upward. When the rotating frame rotates upward, it rotates along the trajectory of the arc rod and squeezes the spring at the same time, so as to buffer the rotating frame and quickly rotate it downward to reset. When the rotating frame rotates up and down reciprocatingly, the larger powder particles on the surface of the screen will be reversed to the inside of the conveying cylinder through the feed valve, and the larger powder particles will be lifted to the discharge valve through the spiral feed rod and slide to the inside of the vacuum melting furnace for secondary processing;

[0017] (3) The vacuum melting gas atomization powder making equipment can perform secondary melting on powder particles with larger particle sizes, making their particle size distribution more uniform and improving processing quality. BRIEF DESCRIPTION OF THE DRAWINGS
