Description

Technical Field

[0001] The utility model relates to the technical field of electrolysis equipment, and specifically refers to an installation structure of an electrolytic cell. Background Technique

[0002] The electrolytic cell is composed of a cell body, an anode, and a cathode. Most use an ion exchange membrane (also called a diaphragm) to separate the anode chamber and the cathode chamber. It is divided into three categories: aqueous solution electrolytic cell, molten salt electrolytic cell, and non-aqueous solution electrolytic cell according to different electrolytes. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce electrolyzed water.

[0003] When assembling the traditional electrolytic cell with a diaphragm, mechanical sealing or adhesive sealing is often used with multiple screws. For details, refer to the Chinese patent "An Electrolytic Cell" with the patent application number CN202321915040.X applied by the applicant.

[0004] However, the above installation structure has complex assembly steps and is not easy to disassemble later to check the state of the electrolytic cell or replace the accessories of the electrolytic cell. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an installation structure of an electrolytic cell with simple loading and unloading in view of the current situation of the prior art.

[0006] The technical solution adopted by the utility model to solve the above technical problem is: an installation structure of an electrolytic cell, including a cell body composed of two cover bodies butt-jointed left and right, characterized in that: the two cover bodies are respectively denoted as a first cover body and a second cover body, and at the port ends of the opposite ends of the first cover body and the second cover body, there are respectively a first sleeve and a second sleeve, and the first sleeve is sleeved on the outer periphery of the second sleeve.

[0007] In order to facilitate the insertion and matching of the first sleeve and the second sleeve, both the first sleeve and the second sleeve are in a cylindrical shape.

[0008] In order to ensure the sealing performance between the first sleeve and the second sleeve, an annular groove extending circumferentially is formed on the inner peripheral wall of the first sleeve, and a sealing ring is installed in the annular groove. The first sleeve is in sealing cooperation with the second sleeve through the sealing ring.

[0009] In order to facilitate the processing of the first sleeve and the second sleeve, both the first cover body and the second cover body are in a cylindrical shape and the port ends of the opposite ends are closed. The edge of the first cover body facing the second cover body forms the first sleeve, and the edge of the second cover body facing the first cover body bends inward and extends to form a stepped portion. The second sleeve protrudes outward from the end wall of the stepped portion, and the end wall of the first sleeve abuts against the stepped portion.

[0010] To improve the aesthetics of the tank body, the outer diameters of the first cover body and the second cover body are the same.

[0011] To facilitate the formation of the electrode chamber, a first pressing ring is convexly provided on the inner peripheral wall of the first sleeve, and the edge of the end of the second sleeve is bent inward to extend to form a second pressing ring. A diaphragm is installed between the first pressing ring and the second pressing ring, and an electrode chamber is formed by surrounding between the diaphragm and each of the cover bodies.

[0012] To improve the sealing performance of the electrode chamber, the first pressing ring and the second pressing ring are hermetically fitted through two annular gaskets arranged side by side, and the periphery of the diaphragm is clamped between the two annular gaskets.

[0013] To facilitate exhaust, an exhaust hole communicating with the electrode chamber is provided at the tank body part corresponding to each electrode chamber.

[0014] To avoid water leakage, a water-repellent breathable film is covered at the exhaust hole.

[0015] To facilitate function expansion, a joint communicating with the electrode chamber is provided at the tank body part corresponding to each electrode chamber.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: By respectively providing a first sleeve and a second sleeve at the opposite end ports of the first cover body and the second cover body, and sleeving the first sleeve on the outer periphery of the second sleeve, the assembly of the tank body is realized, and the installation structure is simple to load and unload.
