Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cells, in particular to a support seat and an electrolytic cell. Background Art

[0002] The electrolytic cell consists of a cell body, an anode and a cathode, and most of them use a diaphragm to separate the anode chamber from the cathode chamber. According to the different electrolytes, they are divided into three categories: aqueous solution electrolytic cell, molten salt electrolytic cell and non-aqueous solution electrolytic cell. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product.

[0003] At present, with the increase in demand, electrolytic cells are developing in the direction of large-scale, the length is constantly increasing, and the axial direction is placed horizontally during normal operation; they are installed by tightening with tension bolts, but this installation method cannot resist the phenomenon that the middle part of the electrolytic cell sags due to gravity. Utility Model Content

[0004] The utility model aims to provide a support seat and an electrolytic cell, so as to provide a technical solution capable of solving the problem that the middle part of the electrolytic cell sags due to gravity.

[0005] Based on this, in a first aspect, the utility model provides a support seat for use in an electrolytic cell, wherein the support seat comprises: a first support structure, a second support structure, and a connecting structure connecting the first support structure and the second support structure.

[0006] The first support structure and the second support structure support the electrolytic cell via the first support plate and the second support plate, wherein the first support plate and the second support plate have structures matching the outer circumference of the electrolytic cell, and the support seat has a hollow structure.

[0007] In the case of adopting the above technical solution, the support seat provided by the utility model includes a first support structure and a second support structure, wherein the first support structure and the second support structure are used to support the electrolytic cell, wherein the first support structure and the second support structure have a structure that matches the outer periphery of the electrolytic cell. Based on this, when the electrolytic cell is placed on the support seat, the support seat can provide a stable support for the electrolytic cell. And when the support seat supports the electrolytic cell from the middle of the electrolytic cell, the technical problem of the middle of the electrolytic cell sagging due to gravity can be solved.

[0008] Since the support base has a hollow structure, the weight of the entire support base can be reduced.

[0009] Preferably, at least one of the first supporting structure, the second supporting structure and the connecting structure has the hollow structure.

[0010] In a possible implementation, a first mounting hole is provided on the first support plate, and / or a second mounting hole is provided on the second support plate; the support seat is fixed to the electrolytic cell through at least one of the first mounting hole and the second mounting hole and a corresponding mounting piece.

[0011] When the above technical solution is adopted, the support base can be fixed together with the electrolytic cell to prevent the poor stability of the electrolytic cell caused by uneven force due to the increase of internal pressure and temperature during operation, thereby improving the reliability of the support base in supporting the electrolytic cell.

[0012] In the actual installation process, since the middle plate of the electrolytic cell is provided with a liquid inlet, a liquid drain port, etc., it involves relatively complicated external piping installation. After the entire electrolytic cell is stacked, the support seat is installed on the middle plate to facilitate installation and debugging and avoid interference.

[0013] The utility model can be operated in the hollow structure of the first supporting structure and / or the second supporting structure to achieve fixing or disassembling the first supporting plate and the electrolytic cell, and fixing or disassembling the second supporting plate and the electrolytic cell.

[0014] In a possible implementation, the first side of the first support structure has a first support plate with a first preset curvature, and the first side of the second support structure has a second support plate with a second preset curvature.

[0015] In the case of adopting the above technical solution, the first support plate and the second support plate have a structure matching the outer circumference of the electrolytic cell. Based on this, since the first support plate and the second support plate have a structure matching the outer circumference of the electrolytic cell, when the electrolytic cell is placed on the support seat, the support seat can provide a stable support for the electrolytic cell.

[0016] In a possible implementation manner, the first preset arc is the same as the second preset arc.

[0017] When adopting the above technical solution, since the first preset curvature and the second preset curvature are the same, the first support plate and the second support plate have the same support area. Therefore, the first support structure and the second support structure can provide the same supporting force for the electrolytic cell, and the entire support seat can provide balanced supporting force for the electrolytic cell.

[0018] In a possible implementation, when the support seat is used to support the electrolytic cell, the first support structure is located between two adjacent tension bolts of the electrolytic cell, and the second support structure is located between two adjacent tension bolts of the electrolytic cell.

[0019] When the above technical solution is adopted, since the first supporting structure and the second supporting structure are both located between two adjacent tensioning bolts of the electrolytic cell, interference of the support seat with the tensioning bolts is avoided.

[0020] In a second aspect, the utility model further provides an electrolytic cell, comprising at least one supporting base as described in the first aspect.

[0021] When the above technical solution is adopted, the support base can be used to support the electrolytic cell at least from the middle area of ​​the electrolytic cell, so the middle part of the electrolytic cell will not sag due to gravity.

[0022] In a possible implementation, the electrolytic cell includes an intermediate bipolar plate assembly, the intermediate bipolar plate assembly includes an intermediate plate frame and two flat plates, the two flat plates are parallel to each other and fixed in an inner circle of the intermediate plate frame at intervals, and the intermediate plate frame and the two flat plates form an electrolyte cavity. The intermediate plate frame is provided with an electrolyte inlet, and the support seat is provided at the intermediate plate frame for supporting the electrolytic cell.

[0023] When the above technical solution is adopted, since the electrolyte inlet is arranged on the intermediate plate frame of the intermediate bipolar plate assembly located in the middle position of the electrolytic cell, the electrolyte enters the electrolyte cavity in the intermediate plate frame from the middle of the electrolytic cell, and then the electrolyte is distributed to both sides from the electrolyte anode distribution channel and the electrolyte cathode distribution channel of the electrolytic cell, and enters the anode chamber and the cathode chamber of the electrolytic cell respectively. Based on this, the distribution path of the electrolyte can be reduced to half the length of the electrolytic cell, which can achieve rapid distribution of the electrolyte. Moreover, since the electrolyte anode distribution channel and the electrolyte cathode distribution channel are alternately arranged along the circumference of the intermediate plate frame, the electrolyte can be diffused into each anode chamber and each cathode chamber at multiple points within a larger central angle range of each plate assembly, which can make the distribution flow field of the electrolyte in the anode chamber and the cathode chamber more uniform, thereby improving the uniformity of the electrolysis reaction and reducing the energy consumption of the electrolytic cell.

[0024] In a possible implementation, the intermediate plate frame is provided with a drain port, a drain pipe is provided on the drain port, the support seat is arranged close to the drain port, and a relief space for accommodating at least part of the drain pipe is provided on the support seat.

[0025] When the above technical solution is adopted, the support seat is arranged close to the drainage port of the intermediate plate frame to support the electrolytic cell. Therefore, the support seat has an escape space for at least part of the drainage pipe to avoid affecting the drainage function of the electrolytic cell.

[0026] In one possible implementation, the electrolytic cell includes a plurality of the support seats, and along the extension direction of the electrolytic cell, the plurality of support seats are arranged at least at the middle bipolar plate assembly of the electrolytic cell and at 1 / 2 of the distance between the middle bipolar plate assembly and either end of the electrolytic cell.

[0027] When the above technical solution is adopted, the utility model can not only solve the technical problem of the middle part of the electrolytic cell sagging due to gravity, but also prevent the two sides of the electrolytic cell from sagging due to gravity. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] First, refer to Figure 1 or Figure 5An embodiment of the utility model provides a support seat, which is applied to an electrolytic cell, and the support seat includes: a first support structure 10, a second support structure 20, and a connecting structure 30 connecting the first support structure 10 and the second support structure 20; the first support structure 10 and the second support structure 20 are used to support the electrolytic cell, wherein the first support structure 10 and the second support structure 20 have a structure matching the outer periphery of the electrolytic cell, and the support seat has a hollow structure.

[0042] In practice, the first supporting structure, the second supporting structure and the connecting structure may be manufactured in an integrated manner to improve the overall stability of the mounting base.

[0043] It should be understood that, since the first support structure 10 and the second support structure 20 have structures matching the outer circumference of the electrolytic cell, when the electrolytic cell is placed on the support seat, the support seat can provide a stable support for the electrolytic cell. And when the support seat supports the electrolytic cell from the middle of the electrolytic cell, the technical problem of the middle of the electrolytic cell sagging due to gravity can be solved.

[0044] It should be further understood that in order to reduce the weight of the support base, the support base is configured as a hollow structure in this practical embodiment. In practice, at least one of the first support structure 10, the second support structure 20 and the connecting structure 30 has the hollow structure.

[0045] In order to reduce the weight of the support base to the greatest extent, in this practical embodiment, the first support structure 10, the second support structure 20 and the connecting structure 30 all have a hollow structure.

[0046] In the embodiment of the utility model, the first side of the first support structure 10 has a first support plate 101 with a first preset curvature, and the first side of the second support structure 20 has a second support plate 201 with a second preset curvature. Both the first preset curvature and the second preset curvature match the outer circumference of the electrolytic cell.

[0047] Based on this, since the first support plate 101 and the second support plate 201 have structures matching the outer circumference of the electrolytic cell, when the electrolytic cell is placed on the support base, the support base can provide a stable support for the electrolytic cell.

[0048] In practice, the second side of the first support structure has a third support plate 102, and the second side of the second support structure has a fourth support plate 202. The third support plate 102 and the fourth support plate 202 are arranged in the working space to support the entire support seat and the electrolytic cell supported on the support seat.

[0049] In some examples, the first predetermined arc is the same as the second predetermined arc.

[0050] Based on this, since the first preset curvature and the second preset curvature are the same, the first support plate and the second support plate have the same support area. Therefore, the first support structure and the second support structure can provide the same supporting force for the electrolytic cell, and the entire support seat can provide balanced supporting force for the electrolytic cell.

[0051] In the embodiment of the utility model, a first mounting hole is provided on the first support plate 101, a second mounting hole is provided on the second support plate 201, and the support seat is fixedly connected to the electrolytic cell through at least one of the first mounting hole and the second mounting hole and a corresponding mounting member.

[0052] It should be understood that, in order to ensure the stability of the connection between the support base and the electrolytic cell, the support base is fixedly connected to the electrolytic cell via the first mounting hole, the second mounting hole and two corresponding mounting members.

[0053] Specifically, the first mounting hole may be a threaded hole, the second mounting hole may also be a threaded hole, the corresponding mounting member may be a bolt, and the support base is fixed to the electrolytic cell through the first mounting hole, the second mounting hole and the corresponding bolt. Based on this, the support base can be used to provide a firm support force for the electrolytic cell, solving the problem of poor stability caused by uneven force during operation of the electrolytic cell due to the increase of internal pressure and temperature in the prior art.

[0054] Further, see Figure 3 or Figure 4 The first middle support portion 103 of the first support structure 10 is provided with a first hollow structure 1031, and the second middle support portion 203 of the second support structure 20 is provided with a second hollow structure. The second hollow structure is arranged corresponding to the first hollow structure, and is no longer shown in the embodiment of the utility model.

[0055] In actual installation, since the middle plate of the electrolytic cell is provided with a liquid inlet, a liquid outlet, etc., it involves a relatively complicated external pipeline installation. After the entire electrolytic cell is stacked, the support seat is assembled on the middle plate to facilitate installation and debugging and avoid interference. Based on this, the staff can use the first hollow structure as an operating space to fix or disassemble the first support plate from the electrolytic cell, and use the second hollow structure as an operating space to fix or disassemble the second support plate from the electrolytic cell, thereby realizing the assembly and disassembly between the support seat and the electrolytic cell.

[0056] In one possible implementation, referring to Figure 1 or Figure 2The connecting structure 30 connects the first supporting structure 10 and the second supporting structure 20 from the second side of the first supporting structure 10 and the second side of the second supporting structure 20, wherein the connecting structure 30 adopts a hollow structure 301 to reduce the weight of the entire supporting base.

[0057] In an embodiment of the utility model, when the support seat is used to support the electrolytic cell, the first support structure is located between two adjacent tensioning bolts of the electrolytic cell, and the second support structure is located between two adjacent tensioning bolts of the electrolytic cell, thereby avoiding interference of the support seat with the tensioning bolts.

[0058] In the second aspect, the utility model also provides an electrolytic cell, referring to Figure 6 , comprising at least one support seat 4 as described in the first aspect. The support seat 4 is used to support the electrolytic cell.

[0059] Further, see Figure 3 The electrolytic cell includes an intermediate bipolar plate assembly, which includes an intermediate plate frame 1 and two flat plates. The two flat plates are fixed in parallel and at intervals in the inner circle of the intermediate plate frame. The intermediate plate frame and the two flat plates form an electrolyte cavity. The intermediate plate frame 1 is provided with an electrolyte inlet 2. The support seat 4 is provided at the intermediate plate frame 1 for supporting the electrolytic cell.

[0060] In the case of adopting the above technical scheme, since the electrolyte inlet is arranged on the intermediate plate frame of the intermediate bipolar plate assembly located in the middle position of the electrolytic cell, the electrolyte enters the electrolyte cavity in the intermediate plate frame from the middle of the electrolytic cell, and then the electrolyte is distributed to both sides from the electrolyte anode distribution channel and the electrolyte cathode distribution channel of the electrolytic cell, and enters the anode chamber and the cathode chamber of the electrolytic cell respectively. Based on this, the distribution path of the electrolyte can be reduced to half the length of the electrolytic cell, which can achieve rapid distribution of the electrolyte, and since the electrolyte anode distribution channel and the electrolyte cathode distribution channel are alternately arranged along the circumference of the intermediate plate frame, the electrolyte can be diffused into each anode chamber and each cathode chamber at multiple points within a larger central angle range of each plate assembly, which can make the distribution flow field of the electrolyte in the anode chamber and the cathode chamber more uniform, thereby improving the uniformity of the electrolysis reaction and reducing the energy consumption of the electrolytic cell.

[0061] Furthermore, based on the above technical solution, the embodiment of the utility model can not only use the support seat to support the electrolytic cell at least from the middle area of ​​the electrolytic cell, so the middle part of the electrolytic cell will not sag due to gravity, but also ensure the entry of electrolyte into the electrolytic cell.

[0062] In a possible implementation, the intermediate plate frame is provided with a drain port, a drain pipe 3 is provided on the drain port, the support seat is provided close to the drain port, and the support seat has an escape space for accommodating at least part of the drain pipe. The drain port is used to discharge the electrolyte. It should be understood that, due to gravity, arranging the drain port below the electrolytic cell is more conducive to the discharge of the electrolyte, and the support seat also needs to support the electrolytic cell body from below the electrolytic cell, so the position of the support seat will interfere with the position of the drain port of the electrolytic cell. Based on this, the support seat in the embodiment of the utility model has an escape space for accommodating at least part of the drain pipe, based on which, it can avoid affecting the drainage function of the electrolytic cell.

[0063] In one possible implementation, the electrolytic cell includes a plurality of the support seats, and along the extension direction d of the electrolytic cell, the plurality of support seats are arranged at least at the middle bipolar plate assembly of the electrolytic cell and at 1 / 2 of the distance between the middle bipolar plate assembly and either end of the electrolytic cell.

[0064] It should be understood that when the length of the electrolytic cell is long, in order to improve the stability of the electrolytic cell, the support seat can be set at the intermediate plate frame 1 of the electrolytic cell at 1 / 2 of the distance from either end of the electrolytic cell. It should be understood that in order to further improve the stability of the electrolytic cell, the support seat can also be set at more positions of the electrolytic cell.

[0065] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0066] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
