Description

Technical Field

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

[0002] Diaphragm electrolyzers were initially used mainly in the chlor-alkali industry to produce chemicals such as chlorine, hydrogen, and sodium hydroxide. However, with the development of technology, their application areas are also expanding. Their characteristic is that a diaphragm is used to separate the positive and negative electrodes to prevent the mixing of the solutions at the two electrodes, but it does not hinder the movement of ions and the passage of current. This design makes each link of the electrolysis process independent of each other, thereby ensuring the stability and consistency of the electrolysis reaction.

[0003] After searching, the Chinese patent with announcement number: CN202107778U discloses a membrane electrolyzer, which includes: an electrolytic cell body with an internal cavity, and an isolation component that isolates the internal cavity of the electrolytic cell body into multiple independent chambers. A first slot is provided on the inner surface of the electrolytic cell body, and the isolation component is inserted into the first slot. When using the diaphragm electrolytic cell, the isolation component and the electrode plate are easy to install and can be replaced by plugging and unplugging. At the same time, the use of traditional connection structures such as flanges is avoided.

[0004] Existing devices have some disadvantages during use. For example, the above-mentioned scheme uses a slot-type method to insert the isolation component into the slot. When the isolation component is inserted into the slot, since the isolation component is not fixed in the slot, the isolation component may become loose due to factors such as current action, vibration or temperature changes during the electrolysis process. The loosening of the isolation component will cause its position to shift, thereby affecting the isolation effect between different chambers, which will lead to problems such as electrolyte mixing and current short circuit, and may even cause safety accidents in severe cases.

The isolation component is arranged on the inner side of multiple second slots to divide the chamber into multiple independent chambers. The diaphragm in the isolation component is used to prevent the mixing of the electrolytes at the two poles while allowing the movement of ions and the passage of current.

[0014] As a preferred embodiment of the above technical solution, the isolation component includes multiple first mounting plates, and the multiple first mounting plates are respectively slidably connected to the inner sides of the corresponding second slots.

[0017] In the above solution, a strong connection structure is formed by respectively opening the first mounting hole and the second mounting hole on the first mounting plate and the second mounting plate, and opening the third mounting hole at the corresponding position on the diaphragm, and then using screws for threaded connection.

[0025] In the above solution, the provision of the second sealing gasket effectively fills the small gap between the second slot and the isolation assembly, ensuring that the electrolyte is strictly confined to the chamber to which it belongs, and preventing cross contamination of electrolytes between different chambers.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] In the utility model, when installing the isolation component, the inclined design of one end of the card block causes the card block to temporarily retract inward when the mounting seat is inserted into the mounting slot. The spring is compressed during the inward contraction of the card block. When the card block moves to the card slot position, the spring releases the compression force, causing the card block to be completely stuck in the card slot, thereby firmly restricting the isolation component in the second slot, ensuring the stability of the isolation component during the electrolysis process, and avoiding various problems caused by looseness.

[0041] As an implementation method in this embodiment, Figure 1 、 Figure 4 and Figure 5As shown, the clamping assembly 3 includes mounting seats 301 respectively fixedly connected to the outer walls on both sides opposite to the top of the plurality of first mounting plates 201, the plurality of mounting seats 301 are each provided with an inner cavity 302, the inner sides of the plurality of inner cavities 302 are slidably connected with a clamping block 303, the ends of the plurality of clamping blocks 303 away from the first mounting plate 201 are arranged in an inclined shape, the ends of the plurality of clamping blocks 303 away from the first mounting plate 201 all pass through the corresponding mounting seats 301 horizontally and are slidably connected to the corresponding mounting seats 301, the plurality of clamping blocks 303 and the inner walls on both sides opposite to the inner cavity 302 are respectively fixedly connected with a mounting ring 304, and the two mounting rings 304 in the same group The middle is fixedly connected with a spring 305, and the clamping assembly 3 also includes a slide groove 306 respectively opened on both sides of the upper end surface of the multiple mounting seats 301, and the inner sides of the two slide grooves 306 of the same group are slidably connected with a U-shaped pressure block 307, and the outer walls on both sides of the multiple clamping blocks 303 are fixedly connected with a slide column 308, and the positions of the slide columns 308 on the opposite sides of the multiple U-shaped pressure blocks 307 are respectively provided with an inclined groove 309, and the multiple U-shaped pressure blocks 307 are respectively slidably connected with the corresponding clamping blocks 303 through the corresponding slide columns 308. The positions of the multiple mounting seats 301 on both sides of the upper end surface of the electrolytic cell body 11 are provided with mounting grooves 310, and the multiple mounting The inner wall of the mounting groove 310 away from the chamber 12 is provided with a card slot 311, and multiple card slots 311 are used in conjunction with corresponding card blocks 303. In the specific use process, when the isolation component 2 is inserted into the second slot 14, the mounting seat 301 is inserted into the mounting groove 310. Due to the inclined design of one end of the card block 303, the mounting seat 301 will temporarily retract inward during the insertion of the mounting groove 310. When the card block 303 retracts inward, the spring 305 is compressed. At this time, the card block 303 will move to the card slot 311 position during the insertion of the mounting seat 301. When the card block 303 moves to the card slot 311 position, the spring 305 is compressed. The compression force is released, and the elastic force of the spring 305 causes the block 303 to be completely engaged in the engagement groove 311. The engagement of the block 303 in the engagement groove 311 restricts the isolation assembly 2 in the second slot 14. When the isolation assembly 2 needs to be removed or replaced, the U-shaped pressing block 307 is simply pressed. The U-shaped pressing block 307 is slidably connected to the slide post 308 on the block 303 via the inclined groove 309 thereon. When the U-shaped pressing block 307 is pressed, the slide post 308 and the block 303 are driven to retract inward, thereby releasing the block 303 from the engagement groove 311. After the block 303 retracts inward, the isolation assembly 2 can be removed from the second slot 14.

[0042] Working principle: Slide the anode plate 15 and the cathode plate 16 into the corresponding first slot 13 in a preset staggered manner. Before installing the isolation component 2, place the diaphragm 204 between the first mounting plate 201 and the second mounting plate 203, tighten the screws 210 and install it inside the first mounting hole 207 and the second mounting hole 208 in the same group, ensuring that the screws 210 can smoothly pass through the corresponding third mounting hole 209. After the diaphragm 204 is installed, the first sealing gasket 41 can ensure that a tight seal is formed between the first mounting plate 201, the second mounting plate 203 and the diaphragm 204. The diaphragm 204 is installed. After the installation is completed, the isolation component 2 is inserted into the second slot 14 through the handle 202. During the insertion of the isolation component 2 into the second slot 14, the mounting base 301 will be inserted into the mounting groove 310. Due to the inclined design of one end of the card block 303, the mounting base 301 will temporarily retract inwards during the insertion of the mounting groove 310. When the card block 303 retracts inwards, the spring 305 is compressed. At this time, the card block 303 will move to the position of the card slot 311 during the insertion of the mounting base 301. When the card block 303 moves to the position of the card slot 311, the spring 305 releases the compression force, and the elastic force of the spring 305 makes the card block 303 3 is completely inserted into the card slot 311. The card block 303 is inserted into the card slot 311 so that the isolation component 2 is confined in the second slot 14. The second sealing gasket 51 effectively fills the small gap between the second slot 14 and the isolation component 2, ensuring that the electrolyte is strictly confined to the chamber 12 to which it belongs, preventing cross contamination of electrolytes between different chambers 12. The electrolyte is injected into each independent electrolytic chamber 12 through the inlet pipe 17. The first through groove 205 and the second through groove 206 expose the diaphragm 204, ensuring that the electrolyte on both sides of the diaphragm 204 is connected, so that the ions It can move freely, facilitating the occurrence of electrolysis reaction. When the electrolysis process is completed, the electrolyte in each electrolysis chamber 12 is discharged into the designated collection container through the outlet pipe 18. When the isolation component 2 needs to be disassembled or replaced, it is only necessary to press the U-shaped pressing block 307. The U-shaped pressing block 307 is slidably connected to the slide column 308 on the block 303 through the inclined groove 309 thereon. When the U-shaped pressing block 307 is pressed, it will drive the slide column 308 and the block 303 to retract inward, thereby releasing the block 303 from the slot 311. After the block 303 retracts inward, the isolation component 2 can be taken out of the second slot 14.
