[0002] When removing slag or refining the holding furnace of cast aluminum alloy, a slag cleaning agent or a refining agent needs to be evenly sprayed into the molten aluminum. Generally, a hand-pushed powder spraying machine is used, and the powder is sprayed into the aluminum liquid by gas pressure.

[0003] For example, the patent with the publication number CN204996601U discloses a powder spraying machine. When refining and removing slag in a melting furnace or a holding furnace such as cast aluminum alloy, an inert gas is connected to the inlet pipe at the bottom of the powder barrel to suspend the refining agent or the slag cleaning agent, and then it is sprayed into the molten aluminum from the upper middle part of the powder barrel for slag removal and degassing. The spraying speed of the refining agent or the slag cleaning agent is uniform, not easily blocked, the structure is simple, and the performance is stable.

[0004] Based on the above patent solution and the existing related technologies, the currently used aluminum refining agent powder spraying machine still has the following problems: 1. Usually, there is a lack of a pushing structure, resulting in the aluminum refining agent being easily blocked at the feed inlet during powder spraying, affecting the powder spraying effect; 2. The moving speed of the nozzle is not proportional to the addition amount of the aluminum refining agent, resulting in a certain error in the addition of the aluminum refining agent; 3. It is not convenient for the staff to control the moving range of the nozzle according to the powder spraying requirements, resulting in a poor use effect. Summary of the Invention

[0019] 1. The powder spraying machine for quantitatively and automatically spraying aluminum refining agent facilitates the staff to push the moving frame. When the motor works, the rectangular movable block can move, which is convenient for the staff to control the powder spraying position of the aluminum refining agent.

[0021] 3. In the powder spraying machine for quantitatively and automatically spraying aluminum refining agent, the quantitatively added aluminum refining agent is sprayed out through two aluminum refining agent nozzles. When two circular connecting rods are inserted into two second connecting grooves, the two aluminum refining agent nozzles can move along with the rectangular movable block, facilitating the spraying of the aluminum refining agent at different positions. When two circular connecting rods are inserted into two first connecting grooves, the two aluminum refining agent nozzles do not move, facilitating the spraying of the aluminum refining agent at the same position, which is convenient for the staff to select a suitable powder spraying area according to the usage requirements. The setting of two second spiral springs plays a resetting role for the two circular connecting rods, making it more convenient for the two circular connecting rods to be inserted into the two second connecting grooves.
