Description

Technical Field

[0001] This utility model relates to the field of hydrogenation equipment technology, and in particular to an alloy powder hydrogenation equipment with controllable hydrogenation purity. Background Technology

[0002] Alloy powder hydrogenation refers to the process of using the volume expansion property of an alloy when it absorbs hydrogen to create cracks and new surfaces in the alloy ingot, thereby promoting further absorption, expansion and fragmentation of hydrogen, and ultimately achieving the purpose of crushing the alloy ingot. This method is called alloy hydrogenation powder making method, which is one of the earliest powder making methods.

[0003] Existing alloy powder hydrogenation equipment mainly focuses on continuous innovation and improvement in alloy powder hydrogenation, thus neglecting the pre-processing of alloy powder. This leads to the agglomeration or wall adhesion of some larger alloy powders after processing, resulting in incomplete processing of alloy powder, waste of raw materials, and impact on processing quality. Furthermore, the current production process of magnesium hydride forms an insulation layer on the surface, preventing the internal magnesium powder from continuing the hydrogenation reaction, thereby reducing its production efficiency. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this utility model is to provide an alloy powder hydrogenation device with controllable hydrogenation purity.

[0006] By adopting the above technical solution, the high-speed rotation of the stirring rod can drive the stirring paddle and the fixing parts to make circular motion, thereby stirring and mixing the hydrides in the pretreatment tank. This can break the insulation layer formed by magnesium hydride, allowing the magnesium powder inside to continue to undergo hydrogenation reaction.

[0007] In a preferred embodiment, the clamping assembly includes fixed circular grooves equidistantly formed inside the fixing member. Each fixed circular groove is slidably connected to a limiting plate, and each limiting plate is fixedly connected to a fixing rod. Each fixing rod is fitted with a spring on its outer side.

[0008] By adopting the above technical solution, the reaction force of the spring can push the limiting plate and the fixing rod to move towards the cleaning brush side, thereby pushing the cleaning brush to come into contact with the inner wall of the pretreatment tank.

[0009] In a preferred embodiment, the pretreatment tank is provided with a catalytic assembly, which includes a refining tank fixedly installed inside a support and located below the pretreatment tank. A heater is fixedly installed at one end of the top of the refining tank, and a pressure controller is fixedly installed at the other end of the top of the refining tank.

[0010] By adopting the above technical solution and by setting up the heater and pressure controller, the hydride and powder in the pretreatment tank can always be kept at a constant temperature and pressure.

[0011] In a preferred embodiment, the catalytic assembly further includes a connecting pipe b fixedly connected to the output end of the heater, a connecting pipe a fixedly connected to the output end of the pressure controller, the end of the connecting pipe a away from the pressure controller extending into the interior of the pretreatment tank, and the end of the connecting pipe b away from the heater extending into the interior of the pretreatment tank.

[0012] By adopting the above technical solution and setting up connecting pipe b and connecting pipe a, gas can be transported to ensure normal regulation of pressure and temperature.

[0015] In a preferred embodiment, a pipe is fixedly connected between the pretreatment tank and the refining tank. A thermal conductivity hydrogen sensor is fixedly installed inside the pipe, and a solenoid valve is installed inside the pipe and below the thermal conductivity hydrogen sensor.

[0016] By adopting the above technical solution and setting up a thermal conductivity hydrogen sensor, the purity of hydrogen can be monitored, and staff can adjust the temperature and pressure environment inside the pretreatment tank according to the required hydrogen purity.

[0017] In a preferred embodiment, a drive motor is fixedly installed on the top of the pretreatment tank, the output shaft of the drive motor extends into the interior of the pretreatment tank and is fixedly connected to the stirring rod, and a feed inlet is fixedly connected to the top of the pretreatment tank.

[0018] By adopting the above technical solution and setting the feed inlet, materials can be fed out.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. In this utility model, the high-speed rotation of the stirring rod drives the stirring paddle and the fixing parts to make circular motion, thereby stirring and mixing the hydrides in the pretreatment tank. This breaks the insulation layer formed by magnesium hydride, allowing the magnesium powder inside to continue the hydrogenation reaction, thus improving its production efficiency. During the rotation of the stirring rod, the alloy powder adhering to the inner wall of the pretreatment tank is scraped off by the cleaning brush and the bottom scraper and added back into the hydrogenation reaction, thereby achieving the purpose of comprehensive processing.

[0021] 2. In this invention, the heater and pressure controller ensure that the hydride and powder in the pretreatment tank are kept at a constant temperature and pressure. This allows the alloy to absorb hydrogen and expand, then release hydrogen and contract, creating cracks and new surfaces. This further promotes hydrogen absorption and expansion, providing a better reaction environment for the hydrogenation reaction. The spring's reaction force pushes the limiting plate and fixing rod towards the cleaning brush, causing the cleaning brush to come into contact with the inner wall of the pretreatment tank, thus improving the scraping effect of the cleaning brush on the inner wall of the pretreatment tank.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-4 A hydrogenation device for alloy powder with controllable hydrogenation purity includes a support 1. A pretreatment tank 2 is fixedly installed at the top of the support 1. A stirring rod 10 is rotatably installed inside the pretreatment tank 2. Stirring paddles 11 are fixedly connected to both sides of the stirring rod 10. Fixing members 12 are fixedly connected to the side of the stirring paddles 11 away from the stirring rod 10. Sliding strips 13 are slidably connected inside the fixing members 12. Cleaning brushes 14 are fixedly connected to the side of the sliding strips 13 away from the fixing members 12. A bottom scraper 23 is fixedly connected to the bottom of the stirring rod 10. A clamping component is provided inside the fixing members 12. After the prepared materials enter the pretreatment tank 2, the high-speed rotation of the stirring rod 10 drives the stirring paddle 11 and the fixing part 12 to make circular motion, thereby stirring and mixing the hydrides in the pretreatment tank 2. This breaks the heat insulation layer formed by magnesium hydride, allowing the magnesium powder inside to continue to undergo hydrogenation reaction, thus improving its production efficiency. During the rotation of the stirring rod 10, the alloy powder adhering to the inner wall of the pretreatment tank 2 is scraped off by the cleaning brush 14 and the bottom scraper 23 and added back into the hydrogenation reaction, thereby achieving the purpose of comprehensive processing.

[0029] Specifically, the clamping assembly includes fixed circular grooves 15 equidistantly formed inside the fixing member 12. Each fixed circular groove 15 has a slidably connected limiting plate 18. Each limiting plate 18 has a fixedly connected fixing rod 17. Each fixing rod 17 has a spring 16 sleeved on its outer side. Through the reaction force of the spring 16, the limiting plate 18 and the fixing rod 17 can be pushed towards the cleaning brush 14, thereby pushing the cleaning brush 14 to abut against the inner wall of the pretreatment tank 2. This improves the scraping effect of the cleaning brush 14 on the inner wall of the pretreatment tank 2. The pretreatment tank 2 contains a catalyst assembly, which includes a refining tank 3 fixedly installed inside the bracket 1 and located below the pretreatment tank 2. One end of the top of the refining tank 3 is fixedly installed with… A heater 4 is provided. The heater 4 and the pressure controller 6 are configured to keep the hydride and powder in the pretreatment tank 2 at a constant temperature and pressure. This allows the alloy to absorb hydrogen and expand, and then release hydrogen and contract, generating cracks and new surfaces, which further promotes hydrogen absorption and expansion. This provides a better reaction environment for the hydrogenation reaction. The pressure controller 6 is fixedly installed at the other end of the top of the refining tank 3. The catalytic assembly also includes a connecting pipe b8 fixedly connected to the output end of the heater 4. A connecting pipe a7 is fixedly connected to the output end of the pressure controller 6. The end of the connecting pipe a7 away from the pressure controller 6 extends into the interior of the pretreatment tank 2, and the end of the connecting pipe b8 away from the heater 4 extends into the interior of the pretreatment tank 2.

[0030] Specifically, the pretreatment tank 2 is equipped with a monitoring component, including a temperature sensor 21 fixedly installed on the inner wall of the pretreatment tank 2. Through the action of the pressure sensor 20 and the temperature sensor 21, the pressure and temperature inside the pretreatment tank 2 can be monitored. When the monitored values ​​are lower than appropriate values, control information is sent to the control panel 22, which then controls the heater 4 and pressure controller 6 to start and stop, ensuring that the pressure and temperature inside the pretreatment tank 2 remain constant. A pressure sensor 20 is fixedly installed on the outside of the pretreatment tank 2, and a control panel 22 is fixedly installed on the top of the bracket 1. A connecting pipe 5 is fixedly connected between the pretreatment tank 2 and the refining tank 3. A thermal conductivity hydrogen sensor 19 is used to monitor the flow. The device can monitor the purity of hydrogen, allowing staff to adjust the temperature and pressure environment inside the pretreatment tank 2 according to the required hydrogen purity, thereby controlling the hydrogen purity. A thermal conductivity hydrogen sensor 19 is fixedly installed inside the pipe 5, and a solenoid valve is installed inside the pipe 5 and below the thermal conductivity hydrogen sensor 19. A drive motor 9 is fixedly installed on the top of the pretreatment tank 2, and the output shaft of the drive motor 9 extends into the interior of the pretreatment tank 2 and is fixedly connected to the stirring rod 10. The rotation of the output shaft of the drive motor 9 can drive the stirring rod 10 to rotate, thereby realizing the transmission of power. A feed inlet is fixedly connected to the top of the pretreatment tank 2 to allow material to be fed in.

[0031] Working principle: First, the operator can feed the prepared materials into the pretreatment tank 2 through the feed inlet and introduce an appropriate amount of hydrogen into the pretreatment tank 2. After the materials enter the pretreatment tank 2, the drive motor 9, pressure controller 6, and heater 4 can be started through the control panel 22. The high-speed rotation of the stirring rod 10 can drive the stirring paddle mesh 11 and the fixing part 12 to make circular motion, thereby stirring and mixing the hydrides in the pretreatment tank 2. This can break the heat insulation layer formed by magnesium hydride, allowing the magnesium powder inside to continue to undergo hydrogenation reaction, thereby improving its production efficiency. During the rotation of the stirring rod 10, the alloy powder adhering to the inner wall of the pretreatment tank 2 is removed by the cleaning brush 14 and the bottom scraper 23. The product is scraped off and reintroduced into the hydrogenation reaction. The pressure and temperature inside the pretreatment tank 2 are monitored by the pressure sensor 20 and the temperature sensor 21. When the monitored values ​​are lower than appropriate, control information is sent to the control panel 22, which then controls the heater 4 and the pressure controller 6 to start and stop, so that the pressure and temperature inside the pretreatment tank 2 remain constant. The hydrogen purity is monitored by the thermal conductivity hydrogen sensor 19. The operator can then adjust the temperature and pressure environment inside the pretreatment tank 2 according to the required hydrogen purity to achieve the purpose of controlling the hydrogen purity. Opening the solenoid valve allows the pretreated product to be transported to the refining tank 3 through the pipe 5 for further preparation.
