Description

Technical Field

[0001] This utility model belongs to the technical field of small ion membrane electrolyzers, specifically relating to a small ion membrane electrolyzer that can be quickly disassembled and assembled. Background Technology

[0002] For small-scale ion-exchange membrane electrolyzers used in experiments, the industry standard for fixing them is a U-shaped flange connection secured with bolts. To ensure no electrolyte leakage at the flange connection, the flatness of the flange surface in contact with the ion-exchange membrane is critical during electrolyzer fabrication. However, the flange assembly and disassembly process is quite cumbersome, time-consuming, and labor-intensive. Furthermore, the tightening torque of each fixing bolt must be consistent, posing a significant challenge to the installer's control of the assembly force. Uneven torque distribution on the fixing bolts can lead to decreased stability of the U-shaped structure, uneven stress on the ion-exchange membrane, electrolyte loss, and consequently, a shortened lifespan of the electrolyzer. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a small-scale ion-exchange membrane electrolyzer that can be quickly disassembled and assembled. Specifically, this utility model includes the following:

[0004] A quick-assembly and disassembly type small ion membrane electrolyzer includes a first tank body, a second tank body, an ion membrane, a first connecting mechanism, and a second connecting mechanism.

[0005] A first communication port is provided on one side of the first tank; the first communication port can be a communication port opened on the side of the first tank, or it can be an open port formed by completely opening one side of the first tank. The specific configuration can be set as needed, and this utility model does not impose too many restrictions.

[0006] A second communication port is provided on one side of the second tank; the second communication port can be a communication port opened on the side of the second tank, or it can be an open port formed by completely opening one side of the second tank. The specific configuration can be set as needed, and this utility model does not impose too many restrictions.

One end of the first connecting cylinder is connected to a first communication port, and the other end of the first connecting cylinder is provided with a first sealing element. The first connecting cylinder is provided with external threads. The connection between one end of the first connecting cylinder and the first communication port is a sealed connection to ensure that the connection can withstand a certain strength and will not leak.

[0008] The second connecting mechanism includes a fixed connecting mechanism and a movable connecting mechanism;

[0009] The fixed connection mechanism includes a fixed connection cylinder, a fixed connection ring, and a second sealing element; one end of the fixed connection cylinder is connected to a second communication port, and the other end is connected to one side of the fixed connection ring.

One end of the movable connecting cylinder is sleeved outside the movable connecting ring, and its inner wall is connected to the outer ring of the movable connecting ring. The inner wall of the movable connecting cylinder is provided with an internal thread. Through the cooperation of the fixed connecting ring and the movable connecting ring, the movable connecting cylinder can be limited, which can both ensure that the movable connecting cylinder can rotate freely outside the fixed connecting cylinder and prevent the movable connecting cylinder from coming off the end of the fixed connecting cylinder.

[0011] The first tank and the second tank are connected by the external thread of the first connecting cylinder and the internal thread of the movable connecting cylinder. The first seal and the second seal are disposed opposite to each other, and the ion membrane is disposed between the first seal and the second seal.

[0018] The beneficial effects of this utility model are:

[0019] When connection is required, the ion membrane is first placed over the second seal on one side of the fixed connecting ring. Then, the end of the first connecting cylinder is inserted into the movable connecting cylinder. The external thread of the first connecting cylinder engages with the internal thread of the movable connecting cylinder. Rotating the movable connecting cylinder causes the first connecting cylinder to move closer to the fixed connecting cylinder under the action of the internal and external threads until the first and second seals press the ion membrane tightly together. This completes the assembly. Disassembly is simple; just rotate the movable connecting cylinder in the opposite direction. This device uses a threaded connection instead of the traditional flange connection. By using multiple seals and multiple cooperating connecting cylinders, a tight connection between the first and second tanks is achieved. Its simple structure and easy disassembly allow for rapid installation and disassembly of small ion membrane electrolyzers. Attached Figure Description
