Description

Technical Field

[0001] This utility model relates to the field of crude magnesium reduction technology, and in particular to a crude magnesium reduction cooling device. Background Technology

[0002] The basic process of reducing magnesium is as follows: after calcining the stone, it is ground into powder, then mixed with ferrosilicon powder and fluorite powder to form pellets. The pellets are placed in a reduction tank for reduction crystallization to obtain primary magnesium. In the reduction crystallization process, a collector is placed in a water jacket. The water jacket cools and removes heat, and the magnesium vapor condenses in the collector after cooling, thus obtaining primary magnesium.

[0003] However, the current cooling method has poor cooling effect, and after a period of use, scale will form inside the water jacket, which further affects the cooling effect and leads to low primary magnesium production efficiency. Utility Model Content

[0004] This invention is a crude magnesium reduction cooling device proposed to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A crude magnesium reduction cooling device includes a water jacket with several circulating water cooling zones evenly distributed on the water jacket. Each circulating water cooling zone is independent of the others. Each circulating water cooling zone includes a water cooling channel, an outlet pipe, and an inlet pipe. The water cooling channel is opened inside the side wall of the water jacket. The outlet pipe is installed in the upper part of the water jacket and communicates with the water cooling channel. The inlet pipe is installed in the lower part of the water jacket and communicates with the water cooling channel.

[0007] By adopting the above technical solution, the water jacket is divided into several independent circulating water cooling zones, reducing the circulation time of the cooling water. This effectively avoids the problem of poor cooling effect caused by excessively long cooling water circulation time, which would affect the magnesium vapor condensation yield. Furthermore, since this device is connected to the top of the reduction tank, which contains a high-temperature flame, the bottom of the water jacket corresponds to the high-temperature zone, and the top corresponds to the low-temperature zone. This technical solution places the cooling water inlet at the bottom of the water jacket and the outlet at the top, allowing the cooling water to enter from the high-temperature zone and exit from the low-temperature zone. This avoids the problem of insufficient cooling effect in the high-temperature zone when the cooling water enters from the low-temperature zone and exits from the high-temperature zone, further improving the cooling effect.

[0008] Furthermore, the water inlet pipe is connected to a section of inclined pipe, and a pressurization component is connected to the inclined pipe.

[0009] Furthermore, the pressurization assembly includes an electric actuator, which is fixedly mounted on the top of the inclined tube. The movable rod of the electric actuator extends through the top of the inclined tube into its interior. A piston is fixedly connected to the end of the movable rod, and the piston slides in a sealed fit against the inner wall of the inclined tube. The electric actuator can push the piston to move along the inclined tube. The movable rod of the electric actuator and the inclined tube are in a sealed sliding connection to ensure the sealing of the connection between the movable rod and the inclined tube and to prevent leakage.

[0010] By adopting the above technical solution, when the cooling circulating water pump malfunctions or needs maintenance, the booster assembly can be used to continue pumping the cooling circulating water, thus avoiding the impact of external water supply problems on the primary magnesium reduction production process.

[0011] Furthermore, a magnetic softening component is connected to the inclined tube.

[0012] Furthermore, the magnetic softening component includes a connecting pipe, and the connecting pipe is fixedly connected to the inclined pipe, with a magnetic descaling device fixedly connected to one end of the connecting pipe.

[0013] Furthermore, a filter screen is provided inside the inclined tube.

[0014] By employing the above technical solution, the magnetizing descaling device introduces a magnetic field into the water flow, magnetizing the minerals and impurities in the water. Under the influence of the magnetic field, these impurities are arranged as closely as possible, forming particles in the water that can be filtered out by the filter screen. This prevents minerals from forming scale on the water jacket wall, which would affect the cooling, crystallization, and collection of magnesium vapor. The magnetic softening component can also serve as a backup. While magnetization is typically performed in the storage tank of a cooling circulation system, there may be malfunctions or maintenance issues with the magnetization device in the storage tank. Therefore, a magnetic softening component is connected to the inlet pipe loop as a backup.

[0015] Furthermore, a solenoid valve is fixedly installed at the bottom opening of the inclined tube. The solenoid valve facilitates control of the opening and closing of the bottom of the inclined tube, making it easier to process the filter screen inside the inclined tube.

[0016] The beneficial effects of this utility model are:

[0017] 1. The present invention provides a solution with multiple circulating water cooling zones, which can reduce the cooling water circulation time, effectively ensure the cooling effect, and thus improve the magnesium vapor condensation yield.

[0018] 2. The circulating water cooling zone of this utility model adopts a water cooling path with water entering from the bottom high-temperature zone and exiting from the top low-temperature zone. This avoids the problem of poor cooling effect in the bottom high-temperature zone when the cooling water first passes through the top low-temperature zone and then enters the bottom high-temperature zone in the traditional method. The circulating water cooling is more uniform and the cooling crystallization effect is better.

[0019] 3. In this utility model, the cooling water needs to be magnetized and filtered before entering the water jacket to prevent scale formation, further improve the cooling effect, and also reduce the maintenance frequency and the impact on the production efficiency of magnesium metal.

[0020] 4. The present invention's technical solution, through the setting of a pressurization component, an inclined tube, and a solenoid valve, can automatically backwash the filter screen periodically, ensuring the filter screen's performance. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1The crude magnesium reduction cooling device shown includes a water jacket 6, which is fixed to the top of the reduction tank 1. A collector 8 is installed inside the water jacket. Because the reduction tank 1 contains a high-temperature flame, the lower part of the water jacket 6 is a high-temperature zone, and the upper part is a low-temperature zone. Three circulating water cooling zones are evenly distributed within the side wall of the water jacket 6. These three circulating water cooling zones are independent of each other, meaning they have independent water inlet and outlet. Each circulating water cooling zone includes a water cooling channel 5, an outlet pipe 7, and an inlet pipe 11. The water cooling channel 5 can be integrally formed inside the water jacket 6, and the water cooling channel 5 can be designed as... Figure 3 As shown, the water-cooling channel 5 is a continuous cavity. If the area of ​​the circulating water-cooling zone is too large, it can also be designed as an S-shaped water channel. The outlet pipe 7 is installed at the top of the water jacket 6, and the inlet pipe 11 is installed at the bottom of the water jacket 6. One end of the water-cooling channel 5 is connected to the inlet pipe 11, and the other end of the water-cooling channel 5 is connected to the outlet pipe 7. The cooling water of each circulating water-cooling zone enters through the inlet pipe 11, flows through the water-cooling channel 5 sequentially through the high-temperature zone and the low-temperature zone, and is then discharged through the outlet pipe 7, thereby cooling the magnesium vapor in the water jacket 6. The coarse magnesium crystals after cooling and crystallization are collected in the collector 8.

[0031] like Figure 1 and 3 As shown, the inlet pipe 11 is connected to a section of inclined pipe 4. The inclined pipe 4 is equipped with a pressurization assembly, which includes an electric push rod 15. The electric push rod 15 is fixedly installed at the top of the inclined pipe 4. The movable rod of the electric push rod 15 extends through the top of the inclined pipe 4 and is fixedly connected to a piston 14. The piston 14 slides in a sealed fit with the inner wall of the inclined pipe 4. The movable rod of the electric push rod 15 is in a sealed sliding connection with the inclined pipe 4. The electric push rod 15 can push the piston 14 to move. When the piston 14 moves into the lower half of the inclined pipe 4, it can increase the water flow rate.

[0032] A magnetic softening component is fixedly connected to one side of the outer surface of the inclined tube 4. The magnetic softening component includes a connecting pipe 3, and the connecting pipe 3 is fixedly connected to the inclined tube 4. A magnetic descaling device 2 is fixedly connected to one end of the connecting pipe 3. The magnetic descaling device 2 magnetizes the minerals and impurities in the water by adding a magnetic field to the water flow, and arranges them as closely as possible under the action of the magnetic field, thereby forming particles in the water.

[0033] An inclined filter screen 13 is fixedly connected inside the inclined tube 4, and the filter screen 13 is located at the connection between the inclined tube 4 and the magnetic softening component. The filter screen 13 can filter impurities in the water.

[0034] A solenoid valve 12 is fixedly installed at the bottom opening of the inclined tube 4. The solenoid valve 12 can control the opening and closing of the bottom opening of the inclined tube 4.

[0035] The magnetic softening component and the pressurizing component can be detachably connected to the inlet pipe via flanges or other means. When the water pump and magnetizing equipment in the circulating cooling water storage tank malfunction or require regular maintenance, the magnetic softening component and the pressurizing component connected by the inclined pipe can serve as backups.

[0036] Working Principle: In use, the external cold water supply equipment is connected to the magnetized descaling device 2 in each circulating water cooling zone. Cold water enters the connecting pipe 3 through the magnetized descaling device 2. During this process, the magnetized descaling device 2 magnetizes the water, causing minerals and impurities in the cold water to transform into particulate impurities. After the cold water enters the inclined tube 4, the particulate impurities are filtered by the filter screen 13. Then, the cold water enters the water cooling channel 5 inside the water jacket 6 through the inlet pipe 11. The cooling water passes through the high-temperature zone and the low-temperature zone in sequence and is discharged through the outlet pipe 7. When it is necessary to clean the filter screen 13, the electric push rod 15 pushes the piston 14 to move to the lower half of the inclined tube 4. Then, the solenoid valve 12 opens, and the electric push rod 15 quickly pushes the water out of the inclined tube 4, thereby achieving the effect of backwashing the filter screen 13. Then, all components are reset.

[0037] This utility model's technical solution sets up multiple circulating water cooling zones and adopts a method of water inlet in the high-temperature zone and water outlet in the low-temperature zone, which makes the circulating water cooling more uniform and effectively improves the cooling and crystallization effect of magnesium vapor.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
