[0002] The electrolytic cell consists of a cell body, an anode and a cathode. Most of them use a diaphragm to separate the anode chamber and the cathode chamber. According to the different electrolytes, they are divided into three categories: aqueous solution electrolytic cells, molten salt electrolytic cells and non-aqueous solution electrolytic cells. The bipolar plate of the electrolytic cell is one of the important components in the electrolytic preparation process. The main function of the bipolar plate is to provide an electric field and a conductivity path, accelerate the reaction rate, and promote the chemical reaction.

[0003] The Chinese utility model type patent with the public document number: CN220149682U discloses an electrode sheet clamping and positioning structure for an electrolytic cell. The utility model moves the limit plate by pulling the limit plate at the same time, so that the limit plate moves inside the through slot. When the limit plate is separated from the top of the limit slot, the electrode sheet body placed inside the limit slot can be taken out and disassembled.

The connecting plate 601 is fixedly connected to the two sides of the tank body 1, the slot 602 and the limiting groove 604 are arranged on the connecting plate 601, the slope 603 is arranged on the two sides of the upper part of the anode 3, the cathode 4 and the bipolar plate 5, the connecting block 605 is fixedly connected to the connecting plate 601, and one of the No. 1 rotating rod 609 is The first end of the slide bar 612 is fixedly connected to the movable plate 608, the two ends of the slide bar 612 are fixedly connected to the movable plate 608, the first rotating rod 609 is movably installed with the connecting block 605, the two ends of the spring 613 are respectively fixedly connected with the movable plate 608 and the connecting plate 601, the positioning component 6 also includes a first movable hole 606 and a first limiting plate 610, the first movable hole 606 is opened on the connecting block 605, the first rotating rod 609 is movably installed in the first movable hole 606, the other end of the first rotating rod 609 is fixedly connected with the first limiting plate 610, the positioning component 6 also includes a second positioning groove 607 and a second positioning rod 611, and the second positioning The slot 607 is provided on the connecting block 605, and the second positioning slot 607 is located above the first movable hole 606, the second positioning rod 611 is fixedly connected to the movable plate 608, and the second positioning rod 611 is movably installed in the second positioning slot 607. The positioning assembly 6 also includes a fixed slot 617, and the fixed slot 617 is provided on the anode 3, the cathode 4 and the bipolar plate 5. The slide bar 612 is movably installed in the fixed slot 617, and the spring piece 613 is located at the side position of the movable plate 608. The plate bodies of the anode 3, the cathode 4 and the bipolar plate 5 are inserted downward into the corresponding slots 602 in sequence, and the anode 3, the cathode 4 and the bipolar plate 5 are moved downward. The inclined surface 603 presses the slide bar 612 downward, and the slide bar 612 rotates sideways under the guidance of the inclined surface 603, and the No. 2 positioning rod 611 moves out of the No. 2 positioning groove 607. The spring piece 613 at the side position is compressed by the rotating movable plate 608, so that the slide bar 612 moves to the side position. When the plate body moves to the lower position of the slide bar 612, the spring piece 613 resets and pushes the movable plate 608 in the opposite direction, so that the No. 2 positioning rod 611 and the slide bar 612 rotate in the opposite direction. After the No. 2 positioning rod 611 is stuck in the No. 2 positioning groove 607, it stops rotating. At this time, the slide bar 612 rotates to the upper position of the plate body, thereby restricting the plate body.

When the plate bodies of the anode 3, the cathode 4 and the bipolar plate 5 are lowered, the push plate 616 moves downward to compress the spring 615. When the height of the plate body is below the slide bar 612 and the slide bar 612 remains vertical, the push plate 616 moves upward to increase the height of the plate body, so that the fixed groove 617 and the slide bar 612 are clamped to each other, making the installation more secure and not easy to loosen. When disassembling, the slide bar 612 is rotated sideways. When the slide bar 612 moves to the side position of the plate body, the push plate 616 pops the plate body upward, making disassembly more convenient.

[0025] It should be noted that the utility model is an electrolytic cell with a self-positioning structure. The anode 3, cathode 4 and one side of the bipolar plate 5 are manually inserted into the slot 602. The inclined surfaces 603 on the upper parts of the anode 3, cathode 4 and bipolar plate 5 press the slide bar 612 downward. At the same time, the anode 3, cathode 4 and bipolar plate 5 press the push plate 616 to move downward, so that the push plate 616 compresses the spring 615 downward. The slide bar 612 rotates to the side under the guidance of the inclined surface 603. The No. 1 rotating rod 609 rotates in the No. 1 movable hole 606. The No. 2 positioning rod 611 moves out of the No. 2 positioning groove 607. The spring piece 613 at the side position is compressed by the rotating movable plate 608, so that the slide bar 612 moves to the side position without blocking the plate body of the anode 3, cathode 4 and bipolar plate 5 from moving downward. When the plate body moves to the position below the slide bar 612, the spring piece 613 resets and pushes the movable plate 608 in the opposite direction. The second positioning rod 611 and the sliding rod 612 rotate in opposite directions. After the second positioning rod 611 is stuck in the second positioning groove 607, it stops rotating. At this time, the sliding rod 612 rotates to the upper position of the plate body and is located above the fixing groove 617, releasing the pressed anode 3, cathode 4 and bipolar plate 5, so that the spring 615 pushes the push plate 616 to move upward, so that the plate body of the anode 3, cathode 4 and bipolar plate 5 moves upward, and the sliding rod 612 is stuck in the fixing groove 617, thereby clamping the plate body, making the plate body installation more fixed and not easy to loosen. When disassembly is required, the sliding rod 612 is rotated sideways, so that the sliding rod 612 moves out of the fixing groove 617 and rotates to the side position of the plate body. At this time, the compressed spring 615 continues to open again, so that the push plate 616 pops out the anode 3, cathode 4 and bipolar plate 5 upward, making installation and disassembly simple and convenient, easy for single-person operation, and saving manpower.
