Description

Technical Field

[0001] This utility model relates to the field of conveying pipe technology, specifically to an anti-solidification rheological conveying pipe for magnesium alloy production lines. Background Technology

[0002] A magnesium alloy production line is a complete set of equipment that produces finished products from magnesium alloy raw materials through processes such as smelting, forming, and processing. The conveying pipe is the core component that connects the various processes and transports molten magnesium alloy. The molten magnesium alloy produced by the smelting furnace needs to be transported from the smelting furnace to the forming equipment, so a conveying pipe is required.

[0003] In the prior art, when the conveying pipe is used for conveying operations, the temperature of the pipe wall is uneven. Molten magnesium alloy is prone to solidify into solid particles in the low temperature area. The solidified magnesium alloy particles will adhere to the inner wall of the conveying pipe, gradually accumulate and form a blockage, which will prevent the molten magnesium alloy from passing through smoothly, thereby reducing the efficiency of magnesium alloy forming. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide an anti-solidification rheological conveying pipe for magnesium alloy production lines. This device can prevent liquid magnesium alloy materials from solidifying due to cooling in the conveying pipe, thereby improving the efficiency of magnesium alloy forming.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An anti-solidification rheological conveying pipe for a magnesium alloy production line includes an oil storage tank. A conveying pipe and an annular pipe sleeved on the outer wall of the conveying pipe are fixedly installed inside the oil storage tank. A motor assembly is installed at one end of the conveying pipe. The power output end of the motor assembly is driven by a rotating shaft. A drive wheel is fixedly connected to the rotating shaft. The drive wheel is driven by a belt and connected to a driven wheel. The driven wheel rotates coaxially with a gear through a connecting shaft. A gear ring is fixedly connected to one side of the annular pipe, meshing with the gear. A heating pipe is installed at the bottom of the oil storage tank, and a heating wire is installed inside the rotating shaft.

[0006] The following are further optimizations of the above technical solution by this utility model: The motor assembly includes a support fixedly mounted on one side of the conveying pipe and a motor mounted on the support. The power output end of the motor is connected to a rotating shaft, and the other end of the rotating shaft is rotatably connected to one side wall of the conveying pipe.

[0007] Further optimization: The upper part of the conveying pipe is fixedly connected to an installation plate, the connecting shaft passes through the installation plate and rotates inside the installation plate, and the driven wheel and gear are both fixedly connected to the connecting shaft.

[0008] Further optimization: The annular tube is slidably sleeved on the outer wall of the conveying pipe, and baffles are uniformly and fixedly connected to the inner wall of the annular tube. The length of the baffles is less than the internal flow height of the annular tube.

[0009] Further optimization: The outer wall of the rotating shaft is fixedly equipped with helical blades, and the top of the conveying pipe is provided with a feed inlet.

[0010] Further optimization: A connecting pipe is fixedly connected to one side of the annular pipe, and a valve is installed on the outer wall of the connecting pipe.

[0011] Further optimization: An oil drain pipe is fixedly connected to one side of the oil storage tank, and an oil drain valve is installed on the outer wall of the oil drain pipe. An oil inlet pipe is also fixedly connected to the top of the oil storage tank.

[0012] This utility model adopts the above-mentioned technical solution, with ingenious conception and reasonable structure. A motor drives the drive wheel to rotate, which in turn drives the driven wheel via belt transmission, thereby driving the gear to rotate. The gear meshes with the gear ring, ultimately driving the annular tube to rotate. This effectively agitates the heat-conducting oil inside the annular tube, making the temperature distribution of the heat-conducting oil more uniform. This preheats all parts of the conveying pipe, effectively preventing the high-temperature liquid magnesium alloy material from solidifying upon contact with the low-temperature conveying pipe. The heating wire inside the spiral shaft further heats the liquid magnesium alloy in the conveying pipe, thus preventing solidification. The spiral blades accelerate the flow of the liquid magnesium alloy in the conveying pipe, preventing solidification caused by prolonged retention in the conveying pipe, and making it convenient to use.

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0016] like Figure 1-5 As shown: A solidification-resistant rheological conveying pipe for a magnesium alloy production line includes an oil storage tank 1, a conveying pipe 2 and an annular pipe 211 sleeved on the outer wall of the conveying pipe 2, a motor assembly at one end of the conveying pipe 2, a rotating shaft 203 connected to the power output end of the motor assembly, a drive wheel 204 fixedly connected to the rotating shaft 203, a driven wheel 206 connected to the drive wheel 204 via a belt 205, and the driven wheel 206 coaxially rotating with a gear 209 via a connecting shaft 207. A gear ring 210 is fixedly connected to one side of the annular pipe 211, and the gear ring 210 meshes with the gear 209. A heating pipe 8 is installed at the bottom of the oil storage tank 1, and a heating wire 3 is also installed inside the rotating shaft 203.

[0017] In this embodiment, the conveying pipe 2 is used to transport and convey the magnesium alloy liquid. The heating wire 3 can maintain the temperature of the magnesium alloy liquid in the conveying pipe 2 and prevent the magnesium alloy liquid from solidifying due to the temperature drop, making it convenient to use.

[0018] Both the annular pipe 211 and the oil storage tank 1 contain heat transfer oil. The heat transfer oil can be a biphenyl-biphenyl ether composite heat transfer oil, which has a maximum heating temperature of 400°C. The heat transfer oil in the oil storage tank 1 is heated by the heating pipe 8 at the bottom of the oil storage tank 1, and then the heat is transferred to the heat transfer oil in the annular pipe 211, raising the temperature of the heat transfer oil in the annular pipe 211 to above 300°C. The heat transfer oil in the annular pipe 211 then transfers the heat to the conveying pipe 2, raising the temperature of the conveying pipe 2 and preventing the magnesium alloy liquid from solidifying due to contact with the low temperature of the conveying pipe 2.

[0019] The motor assembly includes a support base 201 fixedly installed on one side of the conveying pipe 2 and a motor 202 installed on the support base 201. The power output end of the motor 202 is connected to the rotating shaft 203, and the other end of the rotating shaft 203 is rotatably connected to one side wall of the conveying pipe 2.

[0020] The upper part of the conveying pipe 2 is fixedly connected to the mounting plate 208, the connecting shaft 207 passes through the mounting plate 208 and rotates inside the mounting plate 208, and the driven wheel 206 and the gear 209 are both fixedly connected to the connecting shaft 207.

[0021] With this design, when the driven wheel 206 rotates, it will drive the connecting shaft 207 to rotate, and the gear 209 will rotate under the action of the connecting shaft 207, which is convenient to use.

[0022] The annular pipe 211 is slidably sleeved on the outer wall of the conveying pipe 2, and the inner wall of the annular pipe 211 is uniformly and fixedly connected with baffles 7, the length of which is less than the internal flow height of the annular pipe 211.

[0023] With this design, the annular tube 211 can rotate around the conveying tube 2.

[0024] When in use, the motor 202 is started, and the power output end of the motor 202 drives the rotating shaft 203 to rotate. At this time, the driving wheel 204 rotates with the rotating shaft 203, and the driven wheel 206 rotates with the belt 205. Then, the connecting shaft 207 drives the gear 209 to rotate, and the gear 209 drives the gear ring 210 to rotate. Since the gear ring 210 is fixedly connected to the side wall of the annular tube 211, the annular tube 211 rotates around the conveying pipe 2, which facilitates the flow of heat transfer oil in the annular tube 211, thereby ensuring that the heat transfer oil in the annular tube 211 can be heated evenly. The baffle plate 7 can further agitate the heat transfer oil in the annular tube 211, change the flow direction and speed of the heat transfer oil, break the flow inertia of the heat transfer oil, enhance the mixing effect of the heat transfer oil, and facilitate use.

[0025] The outer wall of the rotating shaft 203 is fixedly equipped with a spiral blade 4, and the top of the conveying pipe 2 is provided with a feed inlet 401.

[0026] With this design, the molten magnesium alloy enters the conveying pipe 2 through the feed inlet 401. When the motor 202 starts, the rotating shaft 203 rotates and drives the spiral blades 4 to rotate. Under the action of the spiral blades 4, the magnesium alloy is accelerated to transport, which increases the transport speed of the magnesium alloy liquid and avoids temperature drop and solidification caused by long-term transport inside the conveying pipe 2, making it convenient to use.

[0027] A connecting pipe 5 is fixedly connected to one side of the annular pipe 211, and a valve 501 is installed on the outer wall of the connecting pipe 5.

[0028] In this embodiment, the connecting pipe 5 is used to add or drain the heat transfer oil in the annular pipe 211. When it is necessary to add heat transfer oil into the annular pipe 211, the connecting pipe 5 on the annular pipe 211 is rotated to the top and the valve 501 is opened to add heat transfer oil. When it is necessary to drain the heat transfer oil, the connecting pipe 5 on the annular pipe 211 is rotated to the bottom and the valve 501 is opened to drain the heat transfer oil into the oil storage tank 1 for convenient use.

[0029] An oil drain pipe 6 is fixedly connected to one side of the oil storage tank 1. An oil drain valve 601 is installed on the outer wall of the oil drain pipe 6. An oil inlet pipe 602 is also fixedly connected to the top of the oil storage tank 1.

[0030] Working principle: First, heat transfer oil is added to the oil storage tank 1 and the annular pipe 211. Then, the heating tube 8 is started to work, so that the heat transfer oil in the oil storage tank 1 and the annular pipe 211 is heated. Then, the motor 202 is started to drive the rotating shaft 203 to rotate, so that the driving wheel 204 drives the driven wheel 206 through the belt 205. The driven wheel 206 drives the connecting shaft 207 to rotate in the mounting plate 208. The connecting shaft 207 drives the gear 209. The gear 209 meshes with the gear ring 210, thereby driving the annular pipe 211 to rotate, so that the heat transfer oil in the annular pipe 211 flows and keeps the heat transfer oil in the annular pipe 211 at the same temperature. Then, the heating wire 3 is started. Under the combined action of the heating wire 3 and the heat transfer oil in the annular pipe 211, the conveying pipe 2 is preheated. Then, the feed port 401 is opened to add the magnesium alloy liquid into the conveying pipe 2. At this time, the rotating shaft 203 drives the spiral blade 4 to rotate, which speeds up the transport speed of the magnesium alloy liquid. Preheating the conveying pipe 2 can prevent the magnesium alloy liquid from solidifying due to contact with the low-temperature pipe wall of the conveying pipe 2. Accelerating the transport of the magnesium alloy liquid through the spiral blade 4 can prevent the magnesium alloy liquid from remaining in the conveying pipe 2 for a long time, thereby preventing the magnesium alloy liquid from cooling down and solidifying.

[0031] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
