Description

Technical Field

[0001] This utility model relates to the field of refining technology, specifically to a nitrogen powder injection refining device for an alloy melting furnace. Background Technology

[0002] In the production of alloy materials, smelting is a crucial step. The smelting process not only requires heating the metal raw materials to a molten state, but also refining the melt to remove impurities such as gases and inclusions, thereby improving the purity and performance of the alloy.

[0003] Application number CN201720744689.8 discloses an aluminum alloy powder spraying refining device, including a smelting furnace. A placement plate is positioned above the smelting furnace, and the placement plate is connected to the top of the smelting furnace via several support columns. A drive box is located on the top of the placement plate, and a motor is installed inside the drive box. A gear is mounted on one end of the motor's output shaft. Beneficial effects: This invention uses a motor and a pressure control valve to spray a refining agent into the smelting furnace, replacing manual refining. By spraying nitrogen gas and the refining agent into the smelting furnace, the nitrogen and refining agent work together to achieve a dual refining effect. The output shaft of the motor drives gear one, indirectly driving gear two, which in turn drives a graphite rotor to rotate via a connecting rod. This causes the nitrogen-mixed refining agent to be sprayed out from through holes on the outer surface of the graphite rotor, fully contacting the molten aluminum, thereby separating inclusions and hydrogen from the molten aluminum, greatly improving refining efficiency.

[0004] However, the above solution still has some problems when used: when using the above solution, it is impossible to spray the refining agent mixed with nitrogen evenly into the interior of the smelting furnace. It can only spray one part, which affects the quality of the product after production. Utility Model Content

[0005] To address the problem that the above-mentioned solutions cannot evenly spray the nitrogen-mixed refining agent into the interior of the smelting furnace, and can only spray one part, thus affecting the quality of the product after production, the purpose of this utility model is to provide a nitrogen powder spraying refining device for alloy smelting furnaces.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a nitrogen powder spraying refining device for an alloy smelting furnace, comprising a smelting furnace and a nitrogen cylinder, wherein a furnace cover is installed on the smelting furnace, a first rotating ring is rotatably provided inside the furnace cover, a support rod is fixedly provided on the upper surface of the furnace cover, a fixed plate is fixedly provided at the upper end of the support rod, a second rotating ring rotates inside the fixed plate, an extension plate is fixedly provided on the outer surface of the fixed plate, a first connecting pipe is provided on the extension plate, a powder spraying machine is fixedly provided on the extension plate, a conduit is provided on one side of the powder spraying machine, the other end of the conduit is connected to the first connecting pipe, a second connecting pipe is provided on the nitrogen cylinder, an assembly component is connected to the second connecting pipe and the first connecting pipe, and an auxiliary uniform powder spraying component is connected to the fixed plate and the second rotating ring;

[0007] The auxiliary uniform powder spraying assembly includes a nozzle, a vertical tube inside the first rotating ring and the second rotating ring, the nozzle being fixedly connected to the lower end of the vertical tube, a rectangular tube being fixedly provided at the upper end of the nozzle, a fixed shell being fixedly provided on the upper surface of the fixed plate, a drive motor being disposed inside the fixed shell, a corrugated pipe being fixedly provided on one side of the rectangular tube, the corrugated pipe being connected to the first connecting pipe, a drive motor being fixedly provided on the upper surface of the fixed plate, a connecting rod being provided at the output end of the drive motor, the connecting rod penetrating the fixed plate, a first gear being fixedly sleeved on the outer surface of the connecting rod, and a gear ring being fixedly sleeved on the outer surface of the second rotating ring, the first gear meshing with the gear ring.

[0008] Preferably, the assembly includes a circular hole, and a fixing block is fixedly provided on the outer surface of both the first connecting pipe and the second connecting pipe. The circular hole is opened inside the fixing block, and a bolt is movably inserted into the circular hole. A nut is threaded on the outer surface of the bolt, and the nut is in movable contact with the side of the fixing block.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] This invention allows nitrogen and refining agent to be injected into the furnace by activating the valve on the second connecting pipe in conjunction with the powder sprayer. Activating the drive motor rotates the connecting rod, which in turn rotates the first gear. The first gear drives the meshing gear ring to rotate, thereby rotating the second rotating ring. The second rotating ring, through a vertical pipe, causes the first rotating ring to rotate. The corrugated pipe ensures that the refining agent is evenly sprayed inside the furnace, improving refining quality. Attached Figure Description
