Description

Technical Field

[0001] The utility model relates to the technical field of anhydrous magnesium chloride production process, in particular to a high-temperature anhydrous magnesium chloride particle sampler. Background Art

[0002] The main function of the HCI dryer in the dehydration unit of the magnesium metal plant is to continue drying the semi-dry magnesium chloride particles after hot air drying by contacting them with hot HCI gas in the hydrogen chloride dryer. The dried anhydrous magnesium chloride particles enter the hot dry particle silo, pass through a vibrating feeder, and are then cooled to 75°C with dry air in a particle cooler. They are then transported to the vibrating screen for screening via a bucket elevator and screw conveyor. The screened large particles enter the waste particle silo, and the qualified particles enter the anhydrous particle silo. Because the subsequent magnesium electrolysis unit in the dehydration unit has strict requirements on the moisture and basic magnesium chloride content of the anhydrous magnesium chloride particles, the dried anhydrous magnesium chloride particles must be sampled and tested before entering the qualified anhydrous particle silo. Otherwise, the particles must enter the waste particle silo and be treated as unqualified materials.

[0003] At present, the sampling of dried anhydrous magnesium chloride is done by opening a sampling port on the pipe before the pellets are cooled in the pellet cooler and passed through the bucket elevator into the dry pellet vibrating screen. This sampling method has defects and hidden dangers:

[0004] First, sampling is delayed. Once the sampling fails, the pellets cannot be dried again and can only be treated as waste pellets. Second, during the sampling process, due to the large amount of conveying by the bucket elevator, a large amount of magnesium chloride particles will be sprayed out after the sampling port is opened, which not only increases the waste of magnesium chloride but also poses a dust hazard to the sampling personnel. Third, anhydrous magnesium chloride particles will release a large amount of heat when they come into contact with water. The sprayed or overflowed magnesium chloride particles will come into contact with the exposed parts of the sampler's skin, which may cause burns. Fourth, anhydrous magnesium chloride dry particles will absorb moisture in the air after coming into contact with the air. The current sampling port is not sealed, which will increase the chance of the dry particles coming into contact with the air, thereby affecting the moisture content in the dry particles.

[0005] In summary, there is an urgent need for a high-temperature anhydrous magnesium chloride particle sampler that can minimize moisture absorption and waste of dry particles while reducing safety hazards for sampling personnel. Utility Model Content

[0006] The purpose of the invention of the utility model is to provide a high-temperature anhydrous magnesium chloride particle sampler to address the problems existing in the prior art, which can reduce the moisture absorption of dry particles and the waste of dry particles as much as possible, while reducing the safety hazards of sampling personnel.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A high-temperature anhydrous magnesium chloride particle sampler comprises a sampling tube, wherein the sampling tube is communicated with the interior of a hydrogen chloride dryer;

[0009] The sampling tube includes an outer tube and an inner tube, the outer tube and the inner tube are movably connected, the outer tube is in communication with the interior of the hydrogen chloride dryer, the inner tube extends into the interior of the hydrogen chloride dryer through the outer tube, and a first cover is provided at the end of the outer tube away from the hydrogen chloride dryer, the first cover is used to seal the sampling tube and limit the inner tube;

[0010] A discharge pipe is further provided below the outer tube, the discharge pipe being in communication with the outer tube, and a second cover is provided at the end of the discharge pipe away from the outer tube, the second cover being used to close the discharge pipe and receive samples.

[0011] Preferably, the outer tube is fixedly connected to the hydrogen chloride dryer.

[0012] Preferably, the outer tube is tilted, and the angle formed with the ground is 30° to 45°

[0015] Preferably, the discharge pipe is arranged perpendicular to the ground, communicated with the outer pipe, and fixedly connected to the outer pipe.

[0016] Preferably, the first cover is a screw cap, which is a cylindrical container with one end closed. The inner side of the screw cap is provided with an internal thread, and the end of the outer tube away from the hydrogen chloride dryer is provided with an external thread adapted to the screw cap.

[0017] Preferably, the second cover body is a screw cover, which is a cylindrical container with one end closed.

[0018] Preferably, the closed end of the cylindrical container is a hexagonal prism structure.

[0019] Preferably, pull rings are provided on the closed ends of the first cover and the second cover.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] The present application sets a sampling tube on the hydrogen chloride dryer. Specifically, a sampling port is set on the discharge area of ​​the hydrogen chloride sampler tray after drying is completed, and then connected to the sampling tube; wherein the outer tube of the sampling tube is fixedly connected to the hydrogen chloride dryer. When not sampling, the inner sleeve extends to the material layer, and the sampling tube and the discharge tube are both sealed; when in use, unscrew the first cover, pull out the inner tube until it reaches the opening connected to the discharge tube, and the opening connected to the discharge tube is exposed. At this time, the magnesium chloride particles will fall into the discharge tube, and then the inner tube is pushed into the hydrogen chloride dryer, the first cover is tightened, and the second cover is opened. The magnesium chloride particles are in the second cover, and subsequent testing is carried out;

[0022] The present application sets the sampling tube on the hydrogen chloride dryer. If the pellets are found to be unqualified, the drying time can be extended to continue to remove moisture. There is no problem of sampling lag, and the generation of waste pellets is minimized as much as possible, reducing waste.

In addition, the sampling volume is small, and there will be no waste.

[0024] Finally, when sampling, the entire process is relatively closed, reducing the chance of dry particles coming into contact with air and ensuring the moisture content in the dry particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be described in detail below with reference to the accompanying drawings.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Example 1

[0033] A high-temperature anhydrous magnesium chloride particle sampler includes a sampling tube 1, which is connected to the interior of a hydrogen chloride dryer 2; the sampling tube 1 includes an outer tube 11 and an inner tube 12, which are movably connected. The outer tube 11 is connected to the interior of the hydrogen chloride dryer 2, and the inner tube 12 extends into the interior of the hydrogen chloride dryer 2 through the outer tube 11. A first cover 13 is provided at the end of the outer tube 11 away from the hydrogen chloride dryer 2, and the first cover 13 is used to close the sampling tube 1 and limit the inner tube 12; a discharge tube 3 is further provided below the outer tube 11, and the discharge tube 3 is connected to the outer tube 11. The end of the discharge tube 3 away from the outer tube 11 is provided with a second cover 31, and the second cover 31 is used to close the discharge tube 3 and receive samples. Furthermore, the sampling tube 1 is set at the discharge area of ​​the hydrogen chloride dryer tray after drying is completed, that is, the outer tube 11 is fixed outside the corresponding position and fixedly connected to the hydrogen chloride dryer 2. Sampling is taken here. If the pellets are found to be unqualified, the drying time can be extended to continue to remove moisture to make the pellets qualified, thereby minimizing the generation of waste pellets. The outer tube 11 and the hydrogen chloride dryer 2 can be welded and set outside the hydrogen chloride dryer 2. The inner tube 12 is sleeved with the outer tube 11 and extends into the hydrogen chloride dryer 2 through the outer tube 11. The discharge pipe 3 is connected to the outer tube 11 and can be located at one-third of the outer tube 11 close to the hydrogen chloride dryer 2. The specific location can be selected according to actual conditions.

[0034] When this application is used, first, the state when no sampling is performed is as follows Figure 1As shown, when sampling, unscrew the first cover 13 and pull out the inner tube 12 until the opening connecting the discharge tube 3 and the outer tube 11 leaks out, and the inner tube 12 is not completely pulled out. At this time, since the inner tube 12 is extended into the interior of the hydrogen chloride dryer 2, the pellets will be loose, and then slide out along the outer tube 11 and fall into the discharge tube 3. Furthermore, the outer tube 11 is tilted and the angle formed with the ground is 30° to 45°, which further facilitates the pellets to slide out and fall into the discharge tube 3. Then, the inner tube 12 is pushed into the interior of the hydrogen chloride dryer 2, and the first cover 13 is tightened. At this time, the entire device is in a relatively closed state, and the second cover 31 is unscrewed. The anhydrous magnesium chloride dry particles are in the second cover 31, and subsequent testing is carried out.

[0035] During the entire process, the magnesium chloride dryer 2 is always in a relatively closed state, and the water content of the anhydrous magnesium chloride particles will not change due to sampling. During sampling, a large amount of magnesium chloride particles will not be sprayed out, causing dust damage to the sampling personnel. At the same time, anhydrous magnesium chloride will release a large amount of heat when it comes into contact with water. The structure of the present application can also prevent the sprayed or overflowed magnesium chloride particles from contacting the exposed skin parts of the sampling personnel, thereby causing the risk of burns. At the same time, the present application can relatively control the sampling amount, which can reduce waste to a certain extent.

[0036] Specifically, the outer tube 11 is fixedly connected to the hydrogen chloride dryer 2. The outer tube 11 and the hydrogen chloride dryer 2 can be connected by welding or other methods and are arranged outside the hydrogen chloride dryer 2.

[0037] Specifically, the length of the inner tube 12 is greater than the length of the outer tube 11. The length of the inner tube 12 is greater than the length of the outer tube 11. Preferably, when no sampling is performed, one end of the inner tube 12 extends into the interior of the hydrogen chloride dryer 2, and the other end extends out of the outer tube 11. Figure 4 shown.

[0038] Specifically, the inner tube 12 is further provided with a sealing portion 121, which is a cylindrical structure having a diameter adapted to the inner diameter of the outer tube 11. The position of the sealing portion 121 corresponds to the position of the discharge tube 3. The sealing portion 121 is a portion of the inner tube 12 with a slightly larger diameter, and its setting range can cover the connection between the discharge tube 3 and the outer tube 11. During use, after the inner tube 12 is pulled out for sampling, the inner tube 12 is pushed in. The sealing portion 121 provided on the inner tube 12 can seal the connection between the discharge tube 3 and the outer tube 11. When the discharge tube 3 is opened to remove the pellets, the possibility of air entering the hydrogen chloride dryer 2 can be minimized, the air is isolated to a certain extent, and the water content of the anhydrous magnesium chloride particles is ensured.

[0039] Specifically, the discharge pipe 3 is arranged perpendicular to the ground, communicated with the outer pipe 11, and fixedly connected to the outer pipe 11. The discharge pipe 3 is perpendicular to the bottom surface to facilitate the pellets to fall into the discharge pipe 3, wherein the discharge pipe 3 and the outer pipe 11 can be welded.

[0040] Specifically, the first cover 13 is a screw cap, which is a cylindrical container with one end closed. The inner side of the screw cap is provided with internal threads, and the end of the outer tube 11, away from the hydrogen chloride dryer 2, is provided with external threads that match the screw cap. The screw cap is a cylindrical container with internal threads. During use, a sealing gasket can be used between the screw cap and the outer tube 11 to further seal them. The screw cap connection ensures the airtightness of the entire device.

[0041] Specifically, the second cover 31 is a screw cap, which is a cylindrical container with one end closed. The inner side of the cylindrical container is provided with internal threads, and the end of the discharge tube 3, away from the outer tube 11, is provided with external threads that match the screw cap. A sealing gasket can also be used when connecting the second cover 31 to the discharge tube 3 to further seal it. Furthermore, the cylindrical container structure of the second cover 31 also serves to hold pellets during use.

[0042] Specifically, the closed end of the cylindrical container is a hexagonal prism structure, which makes it easy to unscrew the screw cap.

[0043] Furthermore, pull rings are provided at the closed ends of the first cover 13 and the second cover 31. The pull rings facilitate pulling out the screw cap.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
