Description

Technical Field

[0001] The utility model relates to the technical field of lithium processing, in particular to an isolation structure for a lithium liquid valve. Background Art

[0002] In the production process of lithium, molten salt electrolysis is often used to produce lithium. The low-melting mixture of lithium chloride is electrolyzed by molten salt to precipitate metallic lithium on the cathode of the electrolytic cell. When the molten metallic lithium precipitated on the cathode and floating on the surface of the electrolyte gathers to a certain amount, it is manually fished out and the purified liquid lithium is transported to the mold ingot. The existing lithium liquid transport structure has a lithium liquid valve installed on the transport pipe to control the flow of liquid lithium.

[0003] The existing lithium liquid conveying structure has the following problems: due to the irregular shape of the lithium liquid valve, it is difficult to heat it evenly. At the same time, since it is under high-temperature sequential impact for a long time, the lithium liquid valve seal is easily damaged, causing lithium liquid leakage and fire, burning passers-by, short-circuiting the external heating coil of the pipeline, damaging electrical equipment, etc., posing a major safety hazard.

[0004] Based on the above situation, an isolation structure for a lithium liquid valve is urgently needed to solve the problem of potential safety hazards in the lithium liquid valve. Utility Model Content

[0005] The purpose of the utility model is to solve the problem of safety hazards in the existing lithium liquid conveying structure, because the lithium liquid valve is under high-temperature sequential impact for a long time, there are safety hazards, such as lithium liquid leakage, etc.

[0006] The technical solution of the utility model is as follows:

[0007] An isolation structure for a lithium liquid valve comprises an assembled isolation block with fasteners installed on the isolation block, a valve slot matched with the lithium liquid valve is formed in the isolation block, and the valve slot is connected with a pipe slot matched with a delivery pipeline.

[0008] The existing lithium liquid conveying structure has safety hazards, such as lithium liquid leakage, because the lithium liquid valve is under high temperature and sequential impact for a long time. In this solution, by installing the assembled isolation block on the lithium liquid valve through fasteners, when the lithium liquid valve leaks accidentally, the lithium liquid valve can be operated more safely due to the protective effect of the isolation block, thus solving the problem of safety hazards of the lithium liquid valve.

[0009] Furthermore, in order to make the isolation block cooperate with the valve stem of the lithium liquid valve, one feasible solution is: a positioning groove that cooperates with the valve stem is formed on the valve groove. When this solution is adopted, the positioning groove cooperates with the valve stem, which can reduce the leakage of lithium liquid from solidifying and adhering to the valve stem, making the valve stem difficult to twist.

[0010] Furthermore, in order to prevent the lithium liquid from solidifying and adhering to the valve stem or the delivery pipe, one feasible solution is that a sealing installation groove is formed on the valve groove and the positioning groove. When this solution is adopted, the seal is installed in the seal installation groove, thereby preventing the lithium liquid from solidifying and adhering to the valve stem or the delivery pipe.

[0011] Furthermore, in order to facilitate timely and safe discharge of leaked lithium liquid, one feasible solution is: the positioning groove is connected to a first overflow groove. When this solution is adopted, when lithium liquid leaks, the leaked lithium liquid can be discharged in a timely and safe manner through the first overflow groove.

[0012] Furthermore, a second overflow groove is formed on one side of the isolation block away from the first overflow groove. When this solution is adopted, when the first overflow groove fails, the leaked lithium liquid can also be discharged through the second overflow groove. The use of a redundant structure can further ensure safety.

[0013] Furthermore, the present solution does not limit the specific structure of the fastener. One feasible solution is that the fastener includes a bolt and a nut cooperating with the bolt. When this solution is adopted, the self-locking property of the threaded structure can ensure the sealing of the assembled isolation block.

[0014] Compared with the existing technology, the beneficial effects of the utility model are:

[0015] 1. By installing the assembled isolation block on the lithium liquid valve through fasteners, when the lithium liquid valve leaks accidentally, the lithium liquid valve can be operated more safely due to the protective effect of the isolation block, thereby solving the problem of safety hazards of the lithium liquid valve;

[0016] Second, since the valve groove and the positioning groove are both formed with a seal installation groove, by installing the seal into the seal installation groove, the lithium liquid is prevented from solidifying and adhering to the valve stem or the delivery pipe;

[0017] 3. Since the positioning groove is connected to the first overflow groove, when lithium liquid leaks, the leaked lithium liquid can be discharged in a timely and safe manner through the first overflow groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0029] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0030] Example:

[0031] Please refer to Figure 1 and Figure 2 An isolation structure for a lithium liquid valve includes an assembled isolation block 1 on which a fastener 2 is installed, a valve groove 3 matching the lithium liquid valve is formed in the isolation block 1, and the valve groove 3 is connected to a pipe groove 4 matching the delivery pipeline.

[0032] The existing lithium liquid conveying structure has difficulty in heating evenly due to the irregular shape of the lithium liquid valve. At the same time, due to the long-term high-temperature cycle impact, there are safety hazards, such as lithium liquid leakage. In this solution, by installing the assembled isolation block 1 on the lithium liquid valve through the fastener 2, the irregular shape of the hot lithium liquid valve is converted into a regular shape, which facilitates the installation of the heating component to make it evenly heated and plays a good protective role. When the lithium liquid valve accidentally leaks, the lithium liquid valve can be operated more safely due to the protective effect of the isolation block 1, solving the problem of safety hazards of the lithium liquid valve.

[0033] In this embodiment, the isolation block 1 is preferably made of a non-polar low thermal conductivity material and uses high-frequency electromagnetic heating to heat the lithium liquid valve (when the isolation block is made of a high thermal conductivity material, the lithium liquid valve is heated using resistance heating).

[0034] Preferably, after the isolation block 1 is assembled, an insulating layer is provided on its outer surface. When this solution is adopted, the insulating layer can prevent heat from being quickly transferred to the environment, maintain the internal temperature of the lithium liquid valve, and make the operation of the lithium liquid valve safer.

[0035] This scheme does not limit the specific material of the insulation layer. Silicate fiber products (belts, cloths, blankets, boards, etc.), asbestos products (belts, ropes, cloths, blankets, boards, etc.), ceramic fiber products (alumina, zirconia, etc., belts, ropes, cloths, blankets, boards, foam boards, etc.), and refractory clay can be used.

[0036] In order to make the isolation block 1 cooperate with the valve stem of the lithium liquid valve, one feasible solution is: a positioning groove 5 that cooperates with the valve stem is formed on the valve groove 3. When this solution is adopted, the positioning groove 5 cooperates with the valve stem, which can reduce the leakage of lithium liquid from solidifying and adhering to the valve stem, making the valve stem difficult to twist.

[0037] Reference Figure 3 In order to prevent the lithium liquid from solidifying and adhering to the valve stem or the delivery pipe, one feasible solution is that a sealing member installation groove 31 is formed on both the valve groove 3 and the positioning groove 5. When this solution is adopted, the sealing member is installed in the sealing member installation groove 31 to prevent the lithium liquid from solidifying and adhering to the valve stem or the delivery pipe.

[0038] Reference Figure 2 In order to discharge the leaked lithium liquid in a timely and safe manner, one feasible solution is that the positioning groove 5 is connected to the first overflow groove 6. When this solution is adopted, the leaked lithium liquid can be discharged in a timely and safe manner through the first overflow groove 6 after the lithium liquid leaks.

[0039] A second overflow groove 7 is formed on one side of the isolation block 1 away from the first overflow groove 6. When this solution is adopted, when the first overflow groove 6 fails, the leaked lithium liquid can also be discharged through the second overflow groove 7. The use of a redundant structure can further ensure safety.

[0040] Reference Figure 4 Preferably, a thermistor mounting groove 11 is formed on the isolation block 1, and a thermistor is installed in the thermistor mounting groove 11 to monitor the temperature of the lithium liquid valve.

[0041] Reference Figure 5 This solution does not limit the specific structure of the fastener 2. One feasible solution is that the fastener 2 includes a bolt 21 and a nut 22 that cooperates with the bolt 21. When this solution is adopted, due to the self-locking property of the threaded structure, the assembled isolation block 1 can ensure sealing.

[0042] The working principle of this embodiment:

[0043] The isolation block 1 is assembled on the lithium liquid valve by bolts 21 and nuts 22. Since the valve groove 3 and the positioning groove 5 are both formed with a sealing member installation groove 31, the sealing member is installed in the sealing member installation groove 31 to prevent the lithium liquid from solidifying and adhering to the valve stem or the delivery pipe. When the lithium liquid leaks, the leaked lithium liquid can be discharged in time and safely through the first overflow groove 6 and the second overflow groove 7.

[0044] In order to solve the problem of potential safety hazards in the lithium liquid valve, in this solution, an assembled isolation block 1 is installed on the lithium liquid valve through a fastener 2. When the lithium liquid valve leaks accidentally, the lithium liquid valve can be operated more safely due to the protective effect of the isolation block 1, thereby solving the problem of potential safety hazards in the lithium liquid valve.

[0045] In order to prevent the lithium liquid from solidifying and adhering to the valve stem or the delivery pipe, in the present embodiment, since a seal installation groove 31 is formed on the valve groove 3 and the positioning groove 5, the seal is installed in the seal installation groove 31, thereby preventing the lithium liquid from solidifying and adhering to the valve stem or the delivery pipe.

[0046] In order to discharge the leaked lithium liquid in time and safely, in this solution, since the positioning groove 5 is connected to the first overflow groove 6, the leaked lithium liquid can be discharged in time and safely through the first overflow groove 6 after the lithium liquid leaks.

[0047] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
