[0003] Since inert gas needs to be introduced for reaction when preparing rare earth metal powder, the pressure inside the device will increase after the inert gas is introduced into the device. However, excessive pressure will affect the uniform contact and reaction between the gas and the solid, thereby slowing down the transfer rate of the reactants, reducing the reaction rate, and even causing incomplete reaction. Utility Model Content
[0004] The purpose of the utility model is to provide a preparation device for gasified rare earth metal powder. By setting an automatic pressure relief mechanism, the problem that the pressure in the device increases after an inert gas is introduced into the device, and excessive pressure affects the uniform contact and reaction between the gas and the solid, thereby slowing down the transfer rate of the reactants, reducing the reaction rate, and even causing incomplete reaction is solved.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a preparation device for gasified rare earth metal powder, comprising a reaction cylinder, on which an air intake mechanism, a stirring mechanism and an automatic pressure relief mechanism are arranged;
[0007] An air inlet pipe is connected through the left outer wall of the reaction cylinder, a rotating shaft is rotatably connected to the bottom inner wall of the reaction cylinder, the bottom of the rotating shaft rotates and extends outside the reaction cylinder, a motor is fixedly connected to the bottom extension part of the rotating shaft, a plurality of connecting rods are fixedly connected to the outer wall of the rotating shaft, a plurality of connecting rods are fixedly connected to stirring blocks at one end away from the rotating shaft, and a pressure relief pipe is connected through the right outer wall of the reaction cylinder.
[0008] Furthermore, the automatic pressure relief mechanism comprises a cross support frame fixedly connected to the inner wall of the pressure relief pipe, and an adapter ring is fixedly connected to the inner wall of the pressure relief pipe.
[0009] Furthermore, a piston is slidably connected to the inner wall of the adapter ring, a telescopic rod is fixedly connected to the right side of the piston, and the right end of the telescopic rod is fixedly connected to the cross support frame.
[0010] Further, a spring is sleeved on the telescopic rod. The left end of the spring is fixedly connected to the piston, and the right end of the piston is fixedly connected to the telescopic rod.
[0011] Further, the air inlet mechanism includes a U-shaped heating ring fixedly connected to the inner wall of the air inlet pipe, and a first heating coil is sleeved on the inner wall of the U-shaped heating ring.
[0012] Further, a heat conducting plate is fixedly connected to the inner wall of the U-shaped heating ring. A plurality of air inlet grooves are formed in the heat conducting plate, and all the plurality of air inlet grooves penetrate through the heat conducting plate.
[0013] Further, a sleeve is fixedly sleeved on the outer wall of the bottom side of the reaction cylinder. A plurality of second heating coils are sleeved on the inner wall of the reaction cylinder. An air outlet pipe is provided in a penetrating manner on the outer wall of the back surface of the reaction cylinder.
[0014] Further, a circular ring is fixedly connected to the outer wall of the sleeve. A plurality of support legs are fixedly connected to the bottom of the circular ring. A cover plate is hingedly provided at the top of the reaction cylinder.
[0015] The utility model has the following beneficial effects:
[0016] 1. By setting the automatic pressure relief mechanism, when the air pressure in the reaction cylinder is greater than the elastic threshold of the telescopic rod in the pressure relief pipe during the reaction, the air pressure in the reaction cylinder will push the piston to move to the right, making the spring in a compressed state, and releasing the air pressure in the device to the normal state. After the air pressure in the device is in the normal state, the piston will reset under the action of the spring and cooperate with the adapter ring to be in a sealed state, so that the risk of damage to the equipment structure caused by excessive internal pressure can be effectively reduced, thereby improving the safety of the device. By balancing the pressure, the stability of the reaction process can be ensured, and the consistency and stability of the product can be improved. Moreover, since excessive internal pressure will increase the operating resistance of the equipment and lead to increased energy consumption, automatic pressure relief can reduce the pressure in the device, thereby reducing energy consumption;
[0017] 2. By setting the air inlet mechanism, after the materials required for the reaction are put into the reaction cylinder, the inert gas can be introduced into the reaction cylinder through the air inlet pipe. When the inert gas passes through the air inlet grooves on the heat conducting plate, the heat of the heat conducting plate will preheat the inert gas, so that the molecular kinetic energy can be increased, promoting the gasification reaction. Under high temperature conditions, rare earth metal powders usually need to undergo a gas phase reaction with inert gases. Preheating the inert gas can increase the reaction rate and accelerate the gasification process, and can reduce the influence of the temperature gradient on the reaction device and reaction products, thereby improving the stability of the system. Since the gasification reaction of rare earth metal powders usually needs to be carried out under high temperature conditions, a stable temperature can ensure the uniformity and stability of the reaction.

[0033] By providing the piston 44, the sealing of the device can be changed according to the position change of the piston 44, thereby ensuring that the device can smoothly release pressure when pressure relief is required and ensuring the sealing of the device when pressure relief is not required.
[0034] Among them Figure 3 As shown, a spring 46 is sleeved on the telescopic rod 45 , the left end of the spring 46 is fixedly connected to the piston 44 , and the right end of the piston 44 is fixedly connected to the telescopic rod 45 .
[0035] By providing the spring 46 , the position of the piston 44 can be changed according to the change of the state of the spring 46 , thereby increasing the automaticity of the device.
[0036] Among them, as Figure 4 shown, the intake mechanism 2 includes a U-shaped heating ring 22 fixedly connected to the inner wall of the intake pipe 21, and a first heating coil 23 is sleeved on the inner wall of the U-shaped heating ring 22.
[0037] By setting the intake mechanism 2, the molecular kinetic energy can be increased, promoting the gasification reaction. Under high-temperature conditions, rare earth metal powders usually need to undergo a gas-phase reaction with inert gases. Preheating the inert gas can increase the reaction rate and accelerate the gasification process.
[0038] Among them, as Figure 4 shown, a heat conducting plate 24 is fixedly connected to the inner wall of the U-shaped heating ring 22, and a plurality of intake slots 25 are formed in the heat conducting plate 24, and all the plurality of intake slots 25 penetrate through the heat conducting plate 24.

While heating, start the heating coil one 23 on the U-shaped heating ring 22 to heat the heat conducting plate 24. Introduce the inert gas into the reaction cylinder 1 through the air inlet pipe 21. When the inert gas passes through the air inlet groove 25 on the heat conducting plate 24, the heat of the heat conducting plate 24 will preheat the inert gas, so as to increase its molecular kinetic energy and promote the gasification reaction. Under high temperature conditions, the rare earth metal powder usually needs to undergo a gas-phase reaction with the inert gas. Preheating the inert gas can increase the reaction rate and accelerate the gasification process. After the inert gas is introduced into the reaction cylinder 1, the motor 32 at the bottom of the reaction cylinder 1 can be started. The motor 32 drives the connecting rod 33 on the rotating shaft 31 to rotate, thereby driving the stirring block 34 to stir the materials in the reaction cylinder 1, so as to increase the contact area between the inert gas and the materials, and then improve the reaction rate of the device. When the air pressure in the reaction cylinder 1 is greater than the elastic threshold of the telescopic rod 45 in the pressure relief pipe 41 during the reaction, the air pressure in the reaction cylinder 1 will push the piston 44 to move to the right, making the spring 46 in a compressed state, and releasing the air pressure in the device to the normal state. After the air pressure in the device is in the normal state, the piston 44 will reset under the action of the spring 46 and cooperate with the adapter ring 43 to be in a sealed state, so as to effectively reduce the risk of damage to the equipment structure caused by excessive internal pressure, thereby improving the safety of the device. By balancing the pressure, the stability of the reaction process can be ensured, and the consistency and stability of the product can be improved. The reacted gas flows out through the air outlet pipe 7.
