Description

Technical Field

[0001] This invention relates to the field of alloy processing technology, and more specifically, to a smelting apparatus for producing metal alloy powder. Background Technology

[0002] In the existing technology, smelting equipment for metal alloy powder production plays a crucial role in the metal alloy powder production process. However, the existing technology has some problems that may affect production efficiency and product quality.

[0003] First, the existing technology lacks a mechanism to assist in agitating the alloy powder, which can easily cause material accumulation during the melting and processing of the alloy powder, affecting the melting efficiency.

[0004] Secondly, existing technologies lack devices to prevent the oxidation of alloy powder, which is prone to oxidation in oxygen, leading to a decrease in the quality of finished alloy products.

[0005] Furthermore, the smelting furnace cannot be in a completely vacuum state. When the smelting furnace is in a completely vacuum state, it will cause an imbalance of gas pressure inside and outside the furnace, resulting in an increase in the amount of melt volatilization.

[0006] Finally, the lack of a stirring device for alloy powder in the existing equipment can easily lead to uneven heating and affect processing efficiency. Summary of the Invention

[0007] In view of the problems existing in the prior art, the present invention provides a smelting equipment for the production of metal alloy powder, so as to solve the technical problems mentioned in the background art. Technical solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a smelting device for producing metal alloy powder, comprising a support frame, on which a smelting device, a lifting device, an air inlet device, a vacuum device, and a stirring device are mounted. A U-shaped support plate is mounted on the support frame. The smelting device includes a smelting furnace, a feed inlet, a feed inlet cover plate, a discharge outlet, and a discharge outlet cover plate. The feed inlet is located at the top of the smelting furnace. Multiple rollers are mounted on the smelting furnace. The feed inlet cover plate is movably connected to the feed inlet for sealing the feed inlet. The discharge outlet cover plate is movably connected to the discharge outlet for sealing the discharge outlet. The lifting device includes a first gear, a second gear, a first drive motor, and a turntable. The first gear is movably mounted on the U-shaped support plate.

[0009] The present invention is further configured such that the rotating shaft of the first drive motor is connected to the first gear, the second gear is meshed with the first gear, a turntable is fixedly mounted on one side of the second gear, the other side of the second gear is placed on a bracket, the roller is in contact with the top surface of the turntable, the top surface of the turntable is provided with a plurality of trapezoidal protrusions, and a through hole is opened at the center of the turntable and the second gear, and the turntable and the second gear are sleeved on the smelting furnace through the through hole.

[0010] The present invention is further configured such that the air intake device includes a gas storage tank, a first air intake pipe, a first one-way shut-off valve, a second air intake pipe, and a first flange. The gas storage tank contains inert gas, and the top of the gas storage tank is connected to the first air intake pipe. The first air intake pipe is connected to the first one-way shut-off valve through the first flange, and the first one-way shut-off valve is connected to the second air intake pipe through the first flange. The smelting furnace has an air intake hole, which is connected to the second air intake pipe.

[0011] The present invention is further configured such that the vacuum equipment includes a vacuum machine, a first exhaust pipe, a second one-way shut-off valve, a second exhaust pipe, and a second flange. The top of the vacuum machine is connected to the first exhaust pipe, the first exhaust pipe is connected to the second one-way shut-off valve through the second flange, the second one-way shut-off valve is connected to the second exhaust pipe through the second flange, and the smelting furnace is provided with an extraction hole, which is connected to the second exhaust pipe.

[0012] The present invention is further configured such that the top of the vacuum machine is provided with an air outlet, the air outlet is connected to an air outlet pipe, and the end of the air outlet pipe is provided with a dustproof net.

[0013] The present invention is further configured such that the stirring device includes a second drive motor, two straight bevel gears, a stirring shaft, bearings, and stirring blades. The stirring shaft is provided inside the smelting furnace. A straight bevel gear is connected to the stirring shaft at the top of the smelting furnace. The second drive motor is fixed at the top of the smelting furnace. The shaft of the second drive motor is connected to another straight bevel gear. The two straight bevel gears are meshed together. Multiple bearings are provided on the stirring shaft. The inner ring of the bearing is connected to the stirring shaft, and the outer ring of the bearing is connected to the stirring blades. Beneficial effects

[0014] Compared with the prior art, the present invention provides a smelting device for producing metal alloy powder, which has the following advantages: The lifting device allows the smelting furnace filled with materials to reciprocate up and down, causing the filled materials to vibrate up and down inside the furnace, effectively preventing material accumulation. The first drive motor drives the first gear to rotate, and the first gear meshes with the second gear. The rotation of the first gear drives the rotation of the second gear, which in turn drives the turntable to rotate. The trapezoidal protrusions on the turntable also rotate. When the roller passes the trapezoidal cam, it drives the smelting furnace to reciprocate up and down.

[0015] The vacuum device effectively solves the problem of easy oxidation of alloy powder mentioned in the background technology. First, open the second one-way shut-off valve in the vacuum device, start the vacuum machine, and the vacuum machine will draw the melting furnace into a vacuum state. Then close the second one-way shut-off valve to achieve a vacuum state inside the furnace.

[0016] The air intake device further solves the problem of easy oxidation of alloy powder and plays a role in balancing the gas pressure inside and outside the furnace. After the vacuum device finishes working, there is still a small amount of impurity gas remaining in the melting furnace and the gas pressure outside the melting furnace is much higher than that inside the furnace. At this time, the first one-way shut-off valve is opened, and inert gas will be injected into the melting furnace from the gas storage tank to neutralize the impurity gas remaining in the melting furnace and balance the gas pressure inside and outside the melting furnace. This solves the problem of increased melt volatilization caused by the imbalance of gas pressure inside and outside the furnace mentioned in the background technology.

[0017] The stirring device solves the problem of uneven heating mentioned in the background technology. The second drive motor provides power to the stirring device, and drives the stirring blades to rotate through the transmission of the straight bevel gear to stir the material, so that the material in the furnace is fully stirred, which effectively improves the production efficiency.
