Description

Technical Field

[0001] The present application relates to the technical field of magnesium metal smelting, and in particular to an energy-saving vertical tank magnesium smelting crystallization device. Background Art

[0002] Magnesium smelting crystallization is a process in which magnesium vapor is reduced by silicon (or aluminum) in the presence of calcium oxide under high temperature and vacuum conditions. The magnesium vapor and solid dicalcium silicate (2CaO·SiO2) generated by the reaction are separated from each other and condensed to obtain crystalline magnesium.

[0003] At present, the general magnesium smelting device includes a reduction tank, an upper cover, a lower cover, a central tube and a magnesium crystallizer. The bottom of the reduction tank is a slag outlet, and the upper cover and the lower cover are respectively installed on the upper and lower ports of the reduction tank, and are respectively used to seal the reduction tank when evacuating the vacuum; the magnesium crystallizer is installed in the reduction tank and is used to condense and crystallize magnesium. When in use, the material balls are added from the upper port of the reduction tank, the reduction tank is heated, and magnesium vapor is generated. The magnesium vapor is cooled by the magnesium crystallizer, thereby completing the magnesium smelting crystallization.

[0004] However, after magnesium vapor diffuses out from the inside of the ball, it mainly flows upward into the magnesium crystallizer through the pores between the balls. During the heating and reduction process, the naturally stacked balls shrink and settle downward, increasing the resistance to the overflow of magnesium vapor, thereby reducing the crystallization efficiency. Summary of the invention

[0005] In order to improve the crystallization efficiency of magnesium, the present application provides an energy-saving vertical tank magnesium refining crystallization device.

[0006] The present application provides an energy-saving vertical tank magnesium smelting crystallization device, which adopts the following technical solution: An energy-saving vertical tank magnesium smelting crystallization device comprises a reduction tank, a central tube, a crystallizer, a separation assembly and an adjustment assembly, wherein the reduction tank is vertically arranged, and a material port is provided at the top and the bottom; the central tube is installed in the reduction tank, and a ventilation hole is provided on the central tube; the crystallizer is installed at the top of the reduction tank; the separation assembly is arranged in the reduction tank, and is used to separate reacted material balls from unreacted material balls; the adjustment assembly is arranged on the central tube, and is used to vibrate the separation assembly and increase the gap between the material balls.

[0007] By adopting the above technical scheme, the reduction tank is heated, the material balls generate magnesium vapor, the magnesium vapor enters the crystallizer through the ventilation hole, and the adjusting component causes the separation component to vibrate. Since the volume of the material balls is continuously reduced during the reaction process, the volume difference between the reacted material balls and the unreacted material balls increases, and the gaps between the material balls are increased by vibration. The separation component separates the reacted material balls from the unreacted material balls, making the gaps between the material balls less likely to be blocked, thereby reducing the resistance to the overflow of magnesium vapor and further improving the crystallization efficiency of magnesium.

[0008] Optionally, the separation component includes spiral blade one, spiral blade two and spring one, and spiral blade one is fixedly connected to the center tube; spiral blade two is located above spiral blade one, and a screening hole is provided on spiral blade two; spring one is fixedly connected between spiral blade one and spiral blade two, and is in a compressed state in an initial state.

[0009] By adopting the above technical solution, the material ball is put into the reduction tank, and the material ball slides down along the second spiral blade. Since the free-falling material ball has a critical falling and breaking height, the spiral blade second is provided to make the falling height of the material ball smaller than the critical height, so that the material ball is not easy to break, thereby greatly reducing the breakage rate of the material ball during the loading process. During the reaction, as the volume of the ball decreases continuously, the screening holes and spring 1 are provided so that the ball that has been reacted can easily break away from spiral blade 2 and fall onto spiral blade 1, thereby making it easy for the ball that has been reacted to slide along spiral blade 1 to the material port at the lower end of the reduction tank, making it easy to collect the ball that has been reacted.

[0010] Optionally, the adjustment assembly includes a driving part and an adjustment part, the driving part includes an impeller, a rotating rod and a spur rack, the impeller is rotatably connected to one end of the center tube close to the crystallizer, and is located on one side of the end of the center tube; one end of the rotating rod is rotatably connected to the tooth surface of the impeller, and the other end is rotatably connected to one end of the spur rack; the spur rack is slidably connected in the center tube, and the sliding direction is the axial direction of the center tube; the adjustment part is arranged on the center tube, and is used to make the spiral blade 2 vibrate.

[0011] By adopting the above technical solution, magnesium vapor enters the crystallizer through the ventilation hole. When the magnesium vapor flows at a high speed, the pressure difference on both sides of the impeller increases, the magnesium vapor drives the impeller to rotate, the impeller drives the rotating rod to rotate, the rotating rod drives the spur rack to move, and the spur rack transmits power to the adjustment part. The power is provided by the magnesium vapor, so that the adjustment part can easily vibrate the spiral blade 2, so that the device does not need to add a new power source, thereby reducing the energy saving cost.

[0012] Optionally, the adjusting part includes a connecting rod, a driving gear and a cam, the connecting rod is rotatably inserted into the center tube; the driving gear is coaxially fixedly connected to the connecting rod and is located in the center tube, and the driving gear is meshed with the spur rack; the cam is coaxially fixedly connected to one end of the connecting rod away from the driving gear and is located between spiral blade one and spiral blade two.

[0013] By adopting the above technical solution, the rotating rod drives the spur rack to move, the spur rack drives the driving gear to rotate, the driving gear drives the connecting rod to rotate, the connecting rod drives the cam to rotate, the tip of the cam squeezes the spiral blade 2 to move, the elongation of the spring 1 increases, and the elastic force is accumulated; When the tip of the cam turns away from the spiral blade 2, under the elastic force of the spring 1, the spring 1 drives the spiral blade 2 to reset. Under the gravity of the ball, the spiral blade 2 squeezes the spring 1, the compression amount of the spring 1 increases, and under the elastic force of the spring 1, the spiral blade 2 resets. After reciprocating vibration, the balls on the second spiral blade vibrate, the gaps between the balls increase, and the balls that have been reacted leak out from the gaps between the balls and fall onto the first spiral blade through the screening holes, so that the balls in different states can be easily separated, thereby improving the reaction efficiency. At the same time, as the gap between the balls increases, the overflow space of the magnesium vapor increases, thereby reducing the resistance to the overflow of the magnesium vapor, thereby improving the crystallization efficiency of magnesium.

[0014] Optionally, a scraping assembly is also included, which includes a fixed rod and a cleaning cone, the fixed rod is fixedly connected to the spur rack, a fixed plate is fixedly connected to the fixed rod, and a limiting groove is provided on the fixed plate; the cleaning cone is slidably connected in the limiting groove, and the cleaning cone is adapted to the ventilation hole; a second spring is fixedly connected between the cleaning cone and the bottom of the limiting groove, and the second spring is in a stretched state in the initial state.

[0015] By adopting the above technical solution, the spur rack drives the fixed rod to move, the fixed rod drives the fixed plate to move, the fixed plate drives the cleaning cone to move, the inclined surface of the cleaning cone is squeezed with the ventilation hole, the cleaning cone moves toward the bottom of the limiting groove, the compression amount of the spring two increases, and under the elastic force of the spring two, the cleaning cone is reset and fits tightly with the inside of the ventilation hole, the cleaning cone cleans the residual material attached to the ventilation hole, thereby improving the cleaning effect and further improving the cleaning efficiency.

[0016] Optionally, the adjusting parts are provided in multiple groups, and the multiple groups of adjusting parts are arranged along the axial direction of the central tube.

[0017] By adopting the above technical solution and increasing the number of adjusting parts, it is easy to avoid facility failure caused by damage to a single cam, and thus it is easy to ensure the normal vibration of the spiral blade 2.

[0018] Optionally, the adjustment components are provided in multiple groups, and the multiple groups of adjustment components are evenly arranged around the axis of the central tube.

[0020] Optionally, the scraping components are provided in multiple groups, and the multiple groups of scraping components correspond one-to-one to the multiple groups of adjusting components.

[0021] By adopting the above technical solution and increasing the number of scraping components, it is less likely for waste to remain in the ventilation holes, thereby less likely to hinder magnesium vapor from entering the crystallizer for cooling, thereby improving the crystallization efficiency.
