Description

Technical Field

[0001] The utility model relates to the technical field of electrolysis, in particular to a pole frame assembly and an electrolysis device using the pole frame assembly. Background Art

[0002] The pole frame of a traditional hydrogen production electrolyzer usually includes an anode frame and a cathode frame arranged opposite to each other, with a gasket sandwiched between the anode frame and the cathode frame. As time goes by, the gasket is prone to creep and "diffuse" inside and outside the frame, and the gasket becomes thinner and thinner, thereby reducing the contact stress in the thickness direction of the gasket, reducing the sealing performance of the electrolyzer, and causing alkali liquid leakage; or when the gasket thickness is reduced to a certain extent, the gasket is more likely to be sheared and broken by the sealing water line of the pole frame, resulting in direct contact and short circuit between the upper and lower pole frames, which poses a huge safety hazard. As a result, the service life of the gasket and the entire electrolysis device is short. Utility Model Content

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0036] The utility model provides a pole frame assembly.

[0037] In this utility model technical solution, please refer to Figures 1 to 7 The pole frame assembly includes a first frame 100, a second frame 200, a first gasket 320 and a partition 400; the first frame 100 and the second frame 200 are arranged opposite to each other; the first gasket 320 is clamped between the first frame 100 and the second frame 200; the partition 400 is installed between the first frame 100 and the second frame 200, and the partition 400 includes a limiting plate, and the limiting plate and the side wall of the gasket 300 are mutually limited.

[0038] One of the first frame 100 and the second frame 200 refers to a frame structure for installing an anode plate, wherein the anode plate is installed at a frame opening of one of the first frame 100 and the second frame 200. The other of the first frame 100 and the second frame 200 refers to a frame structure for installing a cathode plate, wherein the cathode plate is installed at a frame opening of the other of the first frame 100 and the second frame 200. In some examples, the first frame 100 and / or the second frame 200 has two frame openings arranged opposite to each other, wherein the frame opening on one side can be used to install the anode plate, and the frame opening on the other side is used to install the cathode plate. When the first frame 100 and the second frame 200 are used in conjunction, the frame opening of the first frame 100 for installing the anode plate can be arranged opposite to the frame opening of the second frame 200 for installing the cathode plate; or the frame opening of the first frame 100 for installing the cathode plate can be arranged opposite to the frame opening of the second frame 200 for installing the anode plate. More specifically, in order to facilitate the installation of the pole plate, the inner wall of the first frame 100 is provided with a first tongue plate 110, and the anode plate is installed on the first tongue plate 110; the inner wall of the second frame 200 is provided with a second tongue plate 210, and the cathode plate is installed on the second tongue plate 210. It can be understood that in the electrolysis device, the first frame 100 and the second frame 200 are arranged opposite to each other, and an electrolysis chamber is formed between the anode plate and the cathode plate. The first frame 100 and the second frame 200 are also separated by a diaphragm to avoid the risk of mixing hydrogen and oxygen during the electrolysis process. In order to reduce the risk of the electrolyte flowing out from between the first frame 100 and the second frame 200, the pole frame assembly also includes a first gasket 320. It should be noted that the pole frame assembly in the technical solution of the utility model can only include the first gasket 320, or can also include other gaskets. By sandwiching the first gasket 320 between the first frame 100 and the second frame 200, the first gasket 320 has a certain sealing effect, thereby reducing the risk of electrolyte flowing out from between the first frame 100 and the second frame 200. It is understandable that in order to achieve a better effect of sealing the electrolyte, the first gasket 320 needs to be in a state of being pre-tightened by the first frame 100 and the second frame 200 (please refer to Figure 4 and Figure 5 Before the first gasket 320 is pre-tightened (see Figure 2 and Figure 3 ), the compressive stress between the first gasket 320 and the first frame 100 and the compressive stress between the first gasket 320 and the second frame 200 is small, and the gap between the first frame 100 and the second frame 200 is also large, which makes it difficult to achieve a good effect of sealing the electrolyte. If the first gasket 320 is compressed and used for a long time, please refer to Figure 6 and Figure 7, the first gasket 320 will inevitably creep in a direction perpendicular to its thickness, and the first gasket 320 will deform and become thinner, thereby making the gap between the first frame 100 and the second frame 200 smaller. At this time, the first gasket 320 may be in a failed state, and it is difficult to achieve a good sealing effect. In the technical solution of the utility model, by setting a partition 400, and the partition 400 is arranged between the first frame 100 and the second frame 200, the partition 400 has a limit plate, and the limit plate and the side wall of the first gasket 320 are mutually limited, the limit plate of the partition 400 prevents the first gasket 320 from creeping in a direction perpendicular to its thickness, thereby delaying the time node of the deformation failure of the first gasket 320 and improving the service life of the first gasket 320. It should be noted that the stiffness of the partition 400 in the technical solution of the utility model is greater than the stiffness of the first gasket 320, so as to achieve the effect of blocking and inhibiting the deformation process of the first gasket 320. In order to reduce the risk of short circuit caused by contact between the first frame 100 and the second frame 200, the first gasket 320 may be an insulating gasket; the partition 400 may also be made of insulating material.

[0039] Specifically, the first gasket 320 may be provided with one, and the first gasket 320 has a side facing the inside of the frame and a side facing the outside of the frame, and the limiting plate of the partition 400 may limit and stop the side of the first gasket 320 facing the inside of the frame and / or the side of the first gasket 320 facing the outside of the frame. For example, the partition 400 may be provided with one limiting plate, and the limiting plate of the partition 400 is only provided on the side of the first gasket 320 facing the inside of the frame or the side of the first gasket 320 facing the outside of the frame; the partition 400 may be provided with two limiting plates, and the two limiting plates are respectively provided on the side of the first gasket 320 facing the inside of the frame and the side of the first gasket 320 facing the outside of the frame; or the partition 400 is a whole, which includes two limiting plates, and the two limiting plates are connected by a connecting portion, and the two limiting plates are respectively provided on the side of the first gasket 320 facing the inside of the frame and the side of the first gasket 320 facing the outside of the frame. In order to reduce the movement of the partition 400 in the direction perpendicular to the thickness of the first gasket 320, the partition 400 can be connected to the first frame 100 and / or the second frame 200 through a connecting piece; or, the first frame 100 and / or the second frame 200 are provided with a mounting groove, and the partition 400 is installed in the mounting groove to limit the movement of the partition 400 in the direction perpendicular to the first gasket 320. The first gasket 320 can also be provided with two or three or more. When there are two first gaskets 320, the two first gaskets 320 can be arranged at intervals, one of the first gaskets 320 is close to the inner edge of the first frame 100 and the second frame 200, and the other first gasket 320 is close to the outer edge of the first frame 100 and the second frame 200. A partition 400 can be provided between the two first gaskets 320, or the partition 400 can also limit and stop both sides of the first gasket 320 close to the outer edge of the first frame 100 and the second frame 200.

[0040] The technical solution of the utility model is to arrange the first frame 100 and the second frame 200 relative to each other, so that after the first frame 100 and the second frame 200 are both installed with electrode plates, an electrolysis chamber is formed between the two electrode plates, so as to facilitate the electrolysis process. By sandwiching the first gasket 320 between the first frame 100 and the second frame 200, the first gasket 320 can seal the electrolyte in the electrolysis chamber, reducing the risk of electrolyte leakage from between the first frame 100 and the second frame 200. By installing the partition 400 between the first frame 100 and the second frame 200, the partition 400 includes a limiting plate, and the limiting plate and the side wall of the first gasket 320 are mutually limited, the partition 400 can block the deformation process of the first gasket 320, thereby reducing the deformation of the first gasket 320, so as to extend the service life of the first gasket 320.

[0041] In an example, please refer to Figures 2 to 7The limiting plate includes a first limiting plate 410, which is arranged on the inner side of the first gasket 320 to limit the inner wall of the first gasket 320; and / or the limiting plate includes a second limiting plate 420, which is arranged on the outer side of the outer first gasket 320 to limit the outer wall of the outer first gasket 320.

[0042] By arranging the first limiting plate 410 on the inner side of the first gasket 320 , the first limiting plate 410 can suppress the deformation tendency of the first gasket 320 toward the electrolysis chamber, further slowing down the deformation speed of the first gasket 320 , thereby further improving the sealing and service life of the first gasket 320 .

[0043] By arranging the first limiting plate 410 on the outside of the first gasket 320, the first limiting plate 410 can suppress the deformation tendency of the first gasket 320 in the direction away from the electrolysis chamber, further slowing down the deformation speed of the first gasket 320, thereby further improving the sealing and service life of the first gasket 320.

[0044] Specifically, the first limiting plate 410 and / or the second limiting plate 420 can be clamped between the first frame 100 and the second frame 200, or connected between the first frame 100 and the second frame 200 through a connecting member to reduce the risk of the first limiting plate 410 and the second limiting plate 420 sliding easily after being subjected to the deformation driving force of the first gasket 320.

[0045] Further, please refer to Figure 3 , Figure 5 as well as Figure 7 The partition 400 further includes a connecting plate 430 , the connecting plate 430 is connected to the limiting plate, and the connecting plate 430 and the first gasket 320 abut against each other in the direction from the first frame 100 to the second frame 200 .

[0046] Specifically, when the limiting plate only has the first limiting plate 410, the connecting plate 430 is only connected to the first limiting plate 410; when the limiting plate only has the second limiting plate 420, the connecting plate 430 is connected to the second limiting plate 420; when the limiting plate includes both the first limiting plate 410 and the second limiting plate 420 mentioned above, the two ends of the connecting plate 430 can be respectively connected to the first limiting plate 410 and the second limiting plate 420, so that the first limiting plate 410, the second limiting plate 420 and the connecting plate 430 form a whole, thereby improving the overall strength of the partition 400 and the installation stability of the partition 400; or when the limiting plate includes both the first limiting plate 410 and the second limiting plate 420 mentioned above, the connecting plate 430 is only connected to the first limiting plate 410 or only connected to the second limiting plate 420.

[0047] When the connecting plate 430 and the first gasket 320 abut against each other in the direction from the first frame 100 to the second frame 200, the connecting plate 430 may abut against the surface of the first gasket 320 facing the first frame 100, or may abut against the surface of the first gasket 320 facing the second frame 200. Alternatively, two connecting plates 430 may be provided, and the two connecting plates abut against the surface of the first gasket 320 facing the first frame 100 and the surface of the first gasket 320 facing the second frame 200, respectively. In this configuration, the existence of the connecting plate 430 limits the movement of the limiting plate in the thickness direction of the first gasket 320, thereby reducing the risk of the partition 400 moving in the thickness direction of the first gasket 320.

[0048] In an example, please refer to Figure 3 , Figure 5 as well as Figure 7 The limiting plate includes a first limiting plate 410 and a second limiting plate 420. The first limiting plate 410 is arranged on the inner side of the first gasket 320 to limit the inner wall of the first gasket 320; the second limiting plate 420 is arranged on the outer side of the outer first gasket 320 to limit the outer wall of the outer first gasket 320; the two ends of the connecting plate 430 are respectively connected to the first limiting plate 410 and the second limiting plate 420.

[0049] Such an arrangement allows the first limiting plate 410, the second limiting plate 420 and the connecting plate 430 to form a whole, thereby improving the overall strength of the partition 400, improving the installation stability of the partition 400, and reducing the risk of the partition 400 moving in the thickness direction of the first gasket 320.

[0050] Further, please refer to Figures 2 to 7 The first gasket 320 includes a first sub-gasket 321 and a second sub-gasket 322 which are arranged opposite to each other. The first sub-gasket 321 and the second sub-gasket 322 respectively abut against the first frame 100 and the second frame 200 ; the connecting plate 430 is sandwiched between the first sub-gasket 321 and the second sub-gasket 322 .

[0051] By making the partition 400 also include a connecting plate 430, and connecting the two ends of the connecting plate 430 are respectively connected to the first limiting plate 410 and the second limiting plate 420, the first limiting plate 410, the second limiting plate 420 and the connecting plate 430 form an integral structure, and the first limiting plate 410 and the second limiting plate 420 are mutually restrained, thereby improving the overall stability of the partition 400. In addition, the first gasket 320 includes a first sub-gasket 321 and a second sub-gasket 322 that are relatively arranged, and the connecting plate 430 is sandwiched between the first sub-gasket 321 and the second sub-gasket 322, and the first sub-gasket 321 and the second sub-gasket 322 respectively abut the first frame 100 and the second frame 200, so that the first sub-gasket 321 and the second sub-gasket 322 are respectively sealed with the first frame 100 and the second frame 200, effectively ensuring a good sealing effect on the electrolyte in the electrolysis chamber. In addition, such a configuration does not affect the configuration of the connecting plate 430 in the partition 400, and it is easy for the user to operate when installing the inner insulating pad and the partition 400, that is, the first sub-gasket 321 can be installed first, then the partition 400, and finally the second sub-gasket 322, thereby reducing the risk of interference between the partition 400 and the first gasket 300 during the installation process.

[0052] In addition, when the first frame 100 has a sealing waterline on the side facing the first sub-gasket 321 and / or the second frame 200 has a sealing waterline on the side facing the second sub-gasket 322, by clamping the connecting plate 430 between the first sub-gasket 321 and the second sub-gasket 322, the risk of short-circuiting the first frame 100 and the second frame 200 after the sealing waterline cuts through the first sub-gasket 321 or the second sub-gasket 322 can be reduced.

[0053] Further, please refer to Figure 3 , Figure 5 as well as Figure 7 The partition 400 further includes an extension plate, which is disposed on a side of the limiting plate away from the first gasket 320 and is disposed between the first frame 100 and the second frame 200 .

[0054] Specifically, the extension plate can be connected to the limiting plate, or can be a separate structure from the limiting plate. When the extension plate and the limiting plate are separate structures, the extension plate and the limiting plate can be arranged in close contact, or a distance can be provided between them.

[0055] By disposing the extension plate between the first frame 100 and the second frame 200 , the risk of short circuit between the first frame 100 and the second frame 200 can be reduced after the first gasket 320 fails.

[0056] In an example, please refer to Figure 3 , Figure 5 as well as Figure 7Based on the scheme that the limiting plate includes a first limiting plate 410, the first limiting plate 410 is arranged on the inner side of the first gasket 320 to limit the inner wall of the first gasket 320, and the extension plate includes a first extension plate 440, which is arranged on the side of the first limiting plate 410 away from the first gasket 320 and is arranged between the first frame 100 and the second frame 200.

[0057] By setting a first extension plate 440, the first extension plate 440 is arranged on the side of the first limiting plate 410 away from the first gasket 320 and is arranged between the first frame 100 and the second frame 200. When the first gasket 320 is deformed and becomes thinner, an isolation effect can be provided between the side of the first frame 100 close to the first limiting plate 410 and the side of the second frame 200 close to the first limiting plate 410, thereby reducing the risk of short circuit due to contact between the first frame 100 and the second frame 200.

[0058] In an example, please refer to Figure 3 , Figure 5 as well as Figure 7 Based on the solution that the limiting plate includes a second limiting plate 420, the second limiting plate 420 is arranged on the outer side of the outer first gasket 320 to limit the outer side wall of the outer first gasket 320, the extension plate includes a second extension plate 450, and the second extension plate 450 is arranged on the side of the second limiting plate 420 away from the first gasket 320, and is arranged between the first frame 100 and the second frame 200.

[0059] By providing a second extension plate 450 on the side of the second limiting plate 420 away from the first gasket 320, and the second extension plate 450 is provided between the first frame 100 and the second frame 200, the first frame 100 and the second frame 200 can be further isolated from each other on the side close to the second limiting plate 420, so as to further reduce the risk of short circuit between the first frame 100 and the second frame 200.

[0060] Further, please refer to Figure 4 and Figure 5 , a gap is provided between the second extension plate 450 and the first frame 100 ; and / or, a gap is provided between the second extension plate 450 and the second frame 200 .

[0061] Specifically, only a gap is provided between the second extension plate 450 and the first frame 100; or, only a gap is provided between the second extension plate 450 and the second frame 200; or, gaps are provided between the second extension plate 450 and the first frame 100 and between the second extension plate 450 and the second frame 200. In this way, the degree of thinning of the first gasket 320 can be intuitively observed through the change in the size of the gap. In an example, the sum of the gap between the second extension plate 450 and the second frame 200 and the gap between the second extension plate 450 and the first frame 100 can be set as the thickness difference between the first gasket 320 from the initial state to the thinning failure, so that when the second extension plate 450 and the first frame 100 and the second extension plate 450 and the second frame 200 are tightly fitted, it can be determined that the outer first gasket 320 is invalid, and the user needs to replace the outer first gasket 320.

[0062] In an example, please refer to Figures 2 to 5 A groove is provided on one side of the first frame 100 facing the first gasket 320 and a groove is provided on one side of the second frame 200 facing the first gasket 320 , and at least a portion of the partition plate 400 and the first gasket 320 are disposed in the groove.

[0063] By providing a groove on the side of the first frame 100 facing the first gasket 320 and the side of the second frame 200 facing the first gasket 320, the first gasket 320 can be installed in the groove. Furthermore, by providing at least a portion of the partition 400 in the groove, after the partition 400 is installed, it can be limited by the side wall of the groove, thereby reducing the risk of the partition 400 sliding to a large extent.

[0064] Further, please refer to Figure 4 and Figure 5 , when the first gasket 320 is in a pre-tightened state, a gap is provided between the partition 400 and a side of the first frame 100 facing the first gasket 320 ; and / or, a gap is provided between the partition 400 and a side of the second frame 200 facing the first gasket 320 .

[0065] By providing a gap between the partition 400 and the side of the first frame 100 facing the first gasket 320, and / or providing a gap between the partition 400 and the side of the second frame 200 facing the first gasket 320, the partition 400 is at least partially suspended between the first frame 100 and the second frame 200, thereby providing a certain deformation space for the first gasket 320 to deform and become thinner. In addition, such an arrangement can also make the first frame 100 and the second frame 200 both effectively fit with the first gasket 320, thereby reducing the risk of reducing the sealing performance by only the abutment between the partition 400 and the first frame 100 and the second frame 200. The user can judge whether the first gasket 320 is invalid by judging whether the partition 400 is suspended between the first frame 100 and the second frame 200. Specifically, when the partition 400 is in a suspended state between the first frame 100 and the second frame 200, it is determined that the first gasket 320 has not failed; when the partition 400 is not in a suspended state between the first frame 100 and the second frame 200, when the partition 400 abuts against the first frame 100 and the second frame 200, it is determined that the first gasket 320 has failed.

[0066] In one example, the first frame 100 and / or the second frame 200 is provided with a sealing rib, and the sealing rib abuts against the first gasket 320 .

[0067] Specifically, only the side of the first frame 100 facing the first gasket 320 is provided with a sealing rib; or only the side of the second frame 200 facing the first gasket 320 is provided with a sealing rib; or both the side of the first frame 100 facing the first gasket 320 and the side of the second frame 200 facing the first gasket 320 are provided with a sealing rib. Such an arrangement improves the sealing performance of the pole frame assembly.

[0068] In an example, please refer to Figures 2 to 7 The pole frame assembly further includes a second gasket 310 , and at least a portion of the partition plate 400 is disposed between the second gasket 310 and the first gasket 320 .

[0069] On the basis of setting the first gasket 320, a second gasket 310 is also included, and by setting at least a part of the partition 400 between the inner gasket 310 and the outer gasket 320, on the one hand, the partition 400 can have a certain blocking effect on the deformation degree of the first gasket 320 and the second gasket 310, thereby extending the service life of the second gasket 310 and the first gasket 320; on the other hand, the first gasket 320 is separated from the second gasket 310, so that the first gasket 320 and the second gasket 310 can still seal the electrolysis chamber mentioned above, and play a double sealing effect, and the setting of the second gasket 310 can also reduce the risk of oxygen and hydrogen separated by the diaphragm in the electrolysis chamber mixing between the first frame 100 and the second frame 200.

[0070] The utility model also proposes an electrolysis device, which includes a pole frame assembly. The specific structure of the pole frame assembly refers to the above embodiment. Since the electrolysis device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.

[0071] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
