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

[0044] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0045] like Figure 1 to Figure 11 As shown, this embodiment proposes an electrolytic cell diaphragm frame, including: an isolation frame 1 and isolation railings 2 distributed in an array on the isolation frame 1, and one end of the isolation frame 1 has a mounting groove 101; a film mounting frame 3 is arranged in the mounting groove 101; there are a plurality of partition plates 4, and the plurality of partition plates 4 are distributed in an array on the film mounting frame 3, and a mounting portion 401 is formed between each two adjacent partition plates 4, and the mounting portion 401 is used to install the diaphragm body.

[0046] In this embodiment, the isolation frame 1 serves as the main structure of the diaphragm frame. The isolation frame 1 plays a supporting and fixing role. Its material is usually corrosion-resistant and has excellent insulation properties to adapt to the chemical environment in the electrolytic cell. The isolation rails 2 are vertically arranged and arrayed on the isolation frame 1 to form a grid structure. The main function of the isolation rails 2 is to enhance the overall strength of the frame and reduce the collapse or deformation of the diaphragm body during use. At the same time, the gap between the isolation rails 2 facilitates the flow of the electrolyte, ensures the efficient electrolysis process, and can also reduce the mutual influence between the two adjacent diaphragm bodies.

[0047] In this embodiment, one end of the isolation frame 1 has a mounting groove 101 for mounting the film mounting frame 3. The shape and size of the mounting groove 101 should be precisely matched with the film mounting frame 3 to ensure that the film mounting frame 3 can be firmly and stably fixed on the isolation frame 1. The function of the film mounting frame 3 is to carry and fix the partition plate 4, and at the same time provide a mounting platform for the diaphragm body. The film mounting frame 3 should have sufficient strength and rigidity to withstand the pressure and vibration that may occur during the electrolysis process. Several partition plates 4 are distributed in a vertical array on the film mounting frame 3. The spacing between the partition plates 4 is carefully designed to form a mounting portion 401 for mounting the diaphragm body. Each mounting portion 401 should be able to tightly and evenly wrap the diaphragm body to ensure the stability of the diaphragm body and the effective distribution of the electrolyte during the electrolysis process. At the same time, the partition plate 4 and the film mounting frame 3 are integrally formed.

[0048] In this embodiment, the working principle and the use process are as follows: first, the film mounting frame 3 is installed in the mounting groove 101 of the isolation frame 1 to ensure that it is firmly fixed. Then, the diaphragm body is placed in each mounting portion 401 in turn, and it is closely fitted with the partition plate 4 by an appropriate fixing method to ensure that the diaphragm body will not be displaced or folded during the electrolysis process. After the diaphragm body is installed, this diaphragm frame is placed in the electrolytic cell so that it can be docked with other components of the electrolytic cell. The electrolysis process is started, and the electrolyte flows in the channel formed by the isolation railing 2, and ion exchange is carried out on both sides of the diaphragm body to achieve electrolysis reaction. Through the above design, the electrolytic cell diaphragm frame proposed in this embodiment has the characteristics of clear structure, convenient assembly, accurate positioning of diaphragm installation, etc., which is conducive to improving the working efficiency and stability of the electrolytic cell, reducing maintenance costs, and is suitable for electrolytic cell systems of various sizes and types. When the diaphragm body on a mounting portion 401 is damaged and needs to be replaced, the operator can disassemble it and then replace it, and it can be quickly disassembled and installed. At the same time, the provision of the partition plate 4 reduces the occurrence of mutual influence between two adjacent diaphragm bodies.

[0049] Optionally, it also includes: there are a plurality of first clamps 5, and the plurality of first clamps 5 are respectively slidably set on a plurality of mounting portions 401; there are a plurality of second clamps 6, and the plurality of second clamps 6 are respectively slidably set on a plurality of mounting portions 401, and are symmetrically arranged with the first clamps 5, and after the first clamps 5 and the second clamps 6 slide, they are used to clamp or cancel the clamping of the diaphragm body.

[0050] In this embodiment, a first clamping plate 5 and a second clamping plate 6 are added to achieve the clamping and loosening of the diaphragm body, thereby enhancing the fixing effect and disassembly convenience of the diaphragm body in the mounting portion 401. A plurality of first clamping plates 5 and second clamping plates 6 are respectively provided, corresponding to the number of mounting portions 401 formed by the partition plate 4, and are respectively slidably provided on each mounting portion 401. The first clamping plates 5 and the second clamping plates 6 are symmetrically provided, that is, a first clamping plate 5 and a second clamping plate 6 are respectively provided on both sides of each mounting portion 401. When the diaphragm body needs to be clamped, the first clamping plate 5 and the second clamping plate 6 are driven to slide along the mounting portion 401 by external operation, so that they are close to each other and fit on the front and rear sides of the diaphragm body, and the diaphragm body is fixed in the mounting portion 401 by the clamping force. When the clamping needs to be canceled or the diaphragm body needs to be replaced, the first clamping plate 5 and the second clamping plate 6 are reversely operated to move them away from each other, thereby releasing the clamping force on the diaphragm body and facilitating the removal or insertion of the diaphragm body. Enhanced fixing effect, the first clamping plate 5 and the second clamping plate 6 clamp the diaphragm body, in addition to relying on the support of the partition plate 4 itself, additionally increase the lateral clamping force, making the diaphragm body more stable during the electrolysis process, reducing displacement or folding caused by factors such as vibration and pressure. Convenient for disassembly and assembly, the clamping and loosening of the diaphragm body can be achieved by sliding the first clamping plate 5 and the second clamping plate 6, without the need for complicated fixing or disassembly steps, greatly improving the installation and replacement efficiency of the diaphragm body, and facilitating the daily maintenance and troubleshooting of the electrolyzer.

[0051] Optionally, it also includes: there are a plurality of bosses 7, the plurality of bosses 7 are arrayed and distributed at the upper and lower ends of one side where the first clamping plate 5 and the second clamping plate 6 are close to each other, and the bosses 7 on the first clamping plate 5 and the second clamping plate 6 are staggered.

[0052] Optionally, the first clamping plate 5 has a clamping groove 501 , the axis of the clamping groove 501 is parallel to the axis of the isolation railing 2 ; and further includes: a clamping platform 8 is arranged on the second clamping plate 6 , the clamping platform 8 is adjacent to the boss 7 , and the clamping platform 8 is used to clamp the diaphragm body in the clamping groove 501 .

[0053] In this embodiment, there are several bosses 7, which are respectively distributed in an array at the upper and lower ends of the side where the first clamping plate 5 and the second clamping plate 6 are close to each other. The bosses 7 on the first clamping plate 5 and the second clamping plate 6 are staggered, that is, when the first clamping plate 5 and the second clamping plate 6 are clamped, the bosses 7 of the two are staggered to form multi-point support and clamping for the diaphragm body. The design of the boss 7 enhances the positioning accuracy of the diaphragm body during clamping, and reduces its sliding or twisting in the mounting portion 401. At the same time, the staggered setting of the boss 7 can evenly disperse the clamping force and reduce the damage to the diaphragm body caused by excessive local pressure. The positioning groove 501 is set on the first clamping plate 5, and its axis is parallel to the axis of the isolation railing 2. The shape and size of the positioning groove 501 should match the edge of the diaphragm body so that the diaphragm body can be embedded therein. The function of the positioning groove 501 is to provide a clear embedding path for the diaphragm body to guide it to be accurately and quickly positioned in the mounting portion 401. At the same time, the positioning groove 501 can also reduce the lateral sliding of the diaphragm body during the clamping process and enhance its stability. The positioning platform 8 is arranged on the second clamping plate 6, adjacent to the boss 7. The shape and size of the positioning platform 8 should match the positioning groove 501. When the first clamping plate 5 and the second clamping plate 6 are clamped, the positioning platform 8 can be inserted into the positioning groove 501 to clamp the side of the diaphragm body in the positioning groove 501. The cooperation between the positioning platform 8 and the positioning groove 501 forms a double locking mechanism for the diaphragm body, further enhancing the fixing effect of the diaphragm body in the mounting portion 401.

[0054] Optionally, it also includes: a first slide plate 9 is slidably set on the isolation frame 1; there are a plurality of first brush strips 10, and the plurality of first brush strips 10 are distributed in an array on the first slide plate 9. After the first slide plate 9 slides, the first brush strips 10 abut against the diaphragm body.

[0055] Optionally, it also includes: a second slide plate 11 is arranged at one end of the first slide plate 9; there are a plurality of second brush strips 12, and the plurality of second brush strips 12 are distributed in an array on the second slide plate 11. After the first slide plate 9 slides, the first brush strip 10 and the second brush strip 12 are respectively located on both sides of the diaphragm body and abut against the diaphragm body.

[0056] In this embodiment, the first slide plate 9 is slidably disposed on the isolation frame 1 and can move along the length direction of the isolation frame 1. There are a plurality of first brush strips 10, which are distributed in an array on the first slide plate 9, and the shape of the first brush strips 10 is adapted to the surface of the diaphragm body. When the first slide plate 9 slides, the first brush strip 10 follows the sliding and contacts the surface of the diaphragm body, and removes the sediment or dirt on the surface of the diaphragm body by brushing. The design of the first slide plate 9 and the first brush strip 10 is intended to achieve single-side cleaning of the diaphragm body. By sliding the first slide plate 9 regularly or when cleaning is required, obstructions on the surface of the diaphragm body can be effectively removed, maintaining its good permeability and ensuring the smooth flow of the electrolyte.

[0057] In this embodiment, the second slide plate 11 is arranged at one end of the first slide plate 9, forming an integral structure with the first slide plate 9, and can also be connected by a connecting piece. There are a plurality of second brush bars 12, which are distributed in an array on the second slide plate 11 and are symmetrically arranged with the first brush bar 10. When the first slide plate 9 slides, the second slide plate 11 and the second brush bar 12 also slide therewith, so that the first brush bar 10 and the second brush bar 12 are respectively located on both sides of the diaphragm body and abut against the diaphragm body. The design of the second slide plate 11 and the second brush bar 12 realizes the simultaneous cleaning of both sides of the diaphragm body. Compared with single-side cleaning, double-side cleaning can more comprehensively and thoroughly remove the deposits on the surface of the diaphragm body, further improve the cleaning effect, and maintain the efficient progress of the electrolysis process.

[0058] Optionally, it also includes: there are a plurality of vibration rods 13, and each isolation railing 2 is respectively provided with a plurality of vibration rods 13 in an array; there are a plurality of extension rods 14, and an extension rod 14 is respectively arranged between each two adjacent first brush strips 10, and after the first slide plate 9 slides, the extension rod 14 abuts against the vibration rod 13 and passes over the vibration rod 13, and the extension rod 14 is used to drive the vibration rod 13 to vibrate.

[0059] In this embodiment, a plurality of vibration rods 13 are arranged in an array in the axial direction of each isolation railing 2. The vibration rod 13 is usually made of a material with a certain elasticity, one end of which is fixed on the isolation railing 2, and the other end is suspended and can vibrate freely. When the first slide plate 9 slides, the first brush bar 10 abuts against the diaphragm body and scrubs. At the same time, the extension rod 14 located between the two adjacent first brush bars 10 contacts and crosses the vibration rod 13, and the vibration rod 13 vibrates through squeezing and impact. These vibrations are transmitted to the isolation railing 2, and then to the entire electrolytic cell diaphragm frame, including the diaphragm body. The extension rod 14 is fixedly connected to the first slide plate 9 and slides with the first slide plate 9. Its shape and size should match the vibration rod 13, and it can accurately and effectively trigger the vibration of the vibration rod 13. The function of the extension rod 14 is to convert the sliding of the first slide plate 9 into triggering the vibration rod 13, and the cleaning effect of the diaphragm body is further enhanced through the vibration of the vibration rod 13. Vibration not only helps to remove stubborn deposits that have not been completely removed during the scrubbing process, but also breaks the adhesion of the deposits to the surface of the diaphragm body through high-frequency vibration, reducing the difficulty of subsequent cleaning. By adding a vibration rod 13 and an extension rod 14, combined with the original scrubbing cleaning, a composite cleaning mode is formed. This mode can more comprehensively and deeply remove various deposits on the surface of the diaphragm body, effectively prevent blockage, and maintain the efficient progress of the electrolysis process.

Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
