Description

Technical Field

[0001] This utility model relates to the field of molten salt separation technology, and in particular to a device for separating molten salt materials. Background Technology

[0002] Hydrogen storage alloys are a new type of alloy that can absorb and release hydrogen under certain conditions. They have excellent cycle life and performance, and are widely used in hydrogen energy storage, battery anode materials, catalysts and other fields.

[0003] Currently, the molten salt displacement method is commonly used to produce hydrogen storage alloys. Specifically, molten salt is used as a reaction medium to generate the target alloy through a displacement reaction at high temperature. The generated target alloy further reacts with other metals to form a hydrogen storage alloy. During the production of hydrogen storage alloys, there will be a mixed state of molten salt, hydrogen storage alloy and other materials. Usually, the molten salt is dissolved and washed out by water washing, and then the slurry is collected by centrifugation.

[0004] Because the displacement process is carried out under high temperature conditions, a large amount of mother liquor is generated during the washing process. The treatment of a large amount of mother liquor increases the production of finished products, reducing the product's price advantage. Therefore, it is necessary to filter and separate the product from the raw materials and by-products before the washing process, while all molten salt materials are still in a molten state.

[0005] In the existing molten salt materials, the molten salt material is prone to cooling and solidification during the filtration and separation process, resulting in low filtration and separation efficiency.

[0006] In view of this, the designer of this utility model developed this utility model. Utility Model Content

[0012] Furthermore, a separation device for molten salt materials is characterized in that: it further includes a cooling component, the pipeline is divided into an outlet section, a cooling section and an external exhaust section, the cooling section is provided with the cooling component, the outlet section is located between the outlet of the mother liquor collection component and the cooling section, and the external exhaust section is located between the cooling section and the vacuum pump.

[0013] Furthermore, the cooling component is a cooling water storage tank, which has a cooling water inlet and a cooling water outlet, and the cooling section is housed within the cooling water storage tank.

[0014] Furthermore, the cooling section is spiral-shaped.

[0016] Furthermore, the mother liquor tank is provided with an openable external drain port, and the heating element is an electric heating wire.

[0017] Furthermore, the filter element is a filter cartridge with a filtration accuracy of less than 5μm.

[0037] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0038] Reference Figures 1-4 As shown, this utility model discloses a separation device for molten salt materials, including: a storage component 1, a heating component 2, a filter component 3, a mother liquor collection assembly 4, and a vacuum pump 5. The heating component 2 is arranged around the storage component 1, the filter component 3 is installed between the storage component 1 and the mother liquor collection assembly 4, and the mother liquor collection assembly 4 is connected to the vacuum pump 5 through a pipeline 6. The vacuum pump can be a water ring pump or other types of vacuum pump to provide a vacuum source for the device.

[0039] When molten salt material needs to be filtered and separated, the molten salt material to be filtered and separated is loaded into the storage container 1 for storage. The heating element 2 heats the storage container 1 to make the molten salt material meet the material conditions for filtration and separation. The molten salt material loaded in the storage container 1 remains in a molten state and does not solidify during the filtration and separation process. After the molten salt material is filtered by the filter element 3, the large-particle hydrogen storage alloy is filtered out, and the small-particle lithium salt flows through the filter element 3 into the mother liquor collection component 4. The vacuum pump 5 is used to extract the gas in the device to form a negative pressure separation environment, so that some difficult-to-filter molten salts can be filtered, thereby improving the filtration and separation efficiency. The overall structure is simple and easy to install.

[0040] In this embodiment, the heating element 2 can be disposed on the outer surface of the storage component 1. The storage component 1 is made of a thermally conductive material. Disposing the heating element 2 on the outer surface of the storage component 1 can improve safety and simplify the structure. The heating element 2 can be an electric heating wire to facilitate heating temperature control, but it is not limited to this. The heating element 2 can be an electric heating element, a gas heating element, a microwave heating element, or a plasma heating element, etc.

[0041] Furthermore, the filter element 3 can be a filter cartridge with a filtration accuracy of less than 5μm, capable of separating hydrogen storage alloys and lithium salts, and the filter cartridge has material properties of high temperature resistance and molten salt corrosion resistance.

[0042] In this embodiment, the present invention also includes a heat insulation layer 77, which covers the outer surface of the heating element 2. The heat insulation layer 77 provides heat insulation for the high-temperature molten salt material, while preventing burns to the operator, ensuring the safety of manual operation, and facilitating operation.

[0043] Furthermore, the mother liquor collection assembly 4 includes a mother liquor tank 41 and a mother liquor collection hopper 42. The mother liquor collection hopper 42 is sealed between the mother liquor tank 41 and the filter element 3. The mother liquor collection hopper 42 and the storage element 1 together limit and fix the filter element. The mother liquor collection hopper 42 is connected to the mother liquor tank 41 through a constricted opening. After the molten salt material of this invention is filtered, the small lithium salt particles enter the mother liquor tank 41 for storage, and hot air also enters the mother liquor tank 41.

[0044] In this embodiment, the mother liquor tank 41 is provided with an openable drain port 411. When the liquid level in the mother liquor tank 41 exceeds the limit, the drain port 411 is opened to allow small lithium salt particles to be discharged from the drain port 411. This allows small lithium salt particles to be discharged while the molten salt material is being filtered and separated, thereby improving operational efficiency. The drain port 411 can be opened manually or controlled by liquid level detection. In the embodiment shown in the figure, the drain port 411 is equipped with a switch valve 9, which controls the opening or closing of the drain port 411.

[0045] In this embodiment, the present invention also includes a cooling component. The pipeline 6 is divided into an air outlet section 61, a cooling section 62, and an external exhaust section 63. The cooling component passes through the cooling section 62. The air outlet section 61 is located between the air outlet of the mother liquor collecting component 4 and the cooling section 62. The external exhaust section 63 is located between the cooling section 62 and the vacuum pump 5. By using the cooling component, the temperature of the air flowing out through the pipeline 6 is reduced, ensuring stable operation of the device and reducing high-temperature failures.

[0046] The cooling component can be a cooling water storage tank 8, which is provided with a cooling water inlet 81 and a cooling water outlet 82. The cooling section 62 is housed within the cooling water storage tank 8. By utilizing the cooling water inlet 81 and the cooling water outlet 82, the cooling water in the cooling water storage tank 8 can be continuously replenished, ensuring the cooling effect of the high-temperature hot air.

[0047] The top of the cooling water storage tank 8 can be open to improve the cooling effect.

[0048] Furthermore, the cooling section 62 can be spiral-shaped to improve the cooling effect.

[0049] The filter element 3 has a handle 31, and the filter element 3 can be pulled out from between the storage container 1 and the mother liquor collection component 4. The operator can pull the filter element 3 out from the storage container 1 and the mother liquor collection component 4 by holding the handle 31 for replacement.
