Description

Technical Field

[0001] The utility model relates to the technical field of ion membrane caustic soda, in particular to a salt-making device for producing ion membrane caustic soda. Background Art

[0002] The salt-making device for ion membrane caustic soda production is a device used to produce caustic soda (sodium hydroxide). Caustic soda is an important chemical raw material, widely used in glass, textile, papermaking, detergent, fertilizer and other industries. The salt-making device for ion membrane caustic soda production mainly consists of the following parts: The brine electrolyzer is the core part of the device, which is used for the electrolysis process. In the electrolyzer, the sodium chloride (salt) solution is decomposed into sodium hydroxide and chlorine by powering on. The ion membrane is a key element in the electrolyzer, which can separate positive and negative ions, allowing only sodium ions to pass through during the electrolysis process and preventing the passage of chloride ions. The membrane chamber is the area separating the positive and negative electrodes of the electrolyzer, and the electrolyzer is divided into the anode membrane chamber and the cathode membrane chamber by the ion membrane. The membrane chamber ensures the separation of cations and anions and avoids the generation and mixing of chlorine. The anode is located in the anode membrane chamber, and after powering on, an oxidation reaction is triggered to produce chlorine and water. The cathode is located in the cathode membrane chamber, and after powering on, a reduction reaction is triggered to produce hydrogen and sodium hydroxide. The ion membrane caustic soda production salt chemical device can realize the process of electrolysis of brine to produce sodium hydroxide and chlorine, and through the selective permeability of the ion membrane, the generated chlorine and hydrogen are collected and utilized separately. This device is highly efficient, environmentally friendly and economical.

[0003] After searching, the patent document (authorization announcement number is CN218795139U) includes: a box body; a connecting column, the connecting column is fixedly installed on the top of both sides of the box body, a placement bucket is fixedly installed on the inner side of the connecting column, a through hole is opened at the bottom of the placement bucket, and a first penetration hole is opened inside the placement bucket; a connecting frame, the connecting frame is fixedly installed on the top of the connecting column, and a motor is fixedly installed on the top of the connecting frame. The utility model provides a salt-making device for ion membrane caustic soda production, which can dissolve its salt in the placement bucket, and then when its volume becomes smaller, it enters the concentration bucket for dissolution, instead of directly in the box body for salt-making work, so there will be no dead angle due to the shape, size, etc. of the box body, resulting in insufficient stirring force, and the inability to effectively and quickly salt-make work, so the work efficiency can be improved.

[0004] However, the above practicality still has shortcomings:

[0005] 1. During the salt treatment, some materials will be on the surface of the liquid, which will cause the materials to fail to be electrolyzed successfully, causing them to be wasted and resulting in a waste of resources.

[0006] 2. During electrolysis, a large amount of by-products are often produced. These by-products will be adsorbed on the ion membrane, thereby reducing the separation efficiency of the ion membrane. Utility Model Content

[0007] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a salt-making device for producing ion membrane caustic soda, which solves the problem that a large amount of by-products are often generated during electrolysis, and these by-products are adsorbed on the ion membrane, thereby reducing the separation efficiency of the ion membrane.

[0008] To achieve the above object, the utility model provides a salt-making device for ion membrane caustic soda production, comprising a box body, a filter barrel is arranged inside the box body, and an auxiliary component is arranged inside the filter barrel, wherein:

[0009] The assisting assembly includes a fixed block, which is fixedly connected to one side of the casing, a rotating rod is rotatably connected inside the fixed block, a first catalyst flow conduit is provided inside the rotating rod, one end of the rotating rod passes through the side wall of the casing and extends into the filter barrel, a thin tube is fixedly connected to the other end of the rotating rod, a short rod is fixedly connected to the side wall of one end of the rotating rod extending into the filter barrel, a second catalyst flow conduit is provided inside the short rod, a stirring plate is fixedly connected to the side wall of the short rod, a scraper rod is fixedly connected to the end of the short rod away from the rotating rod, and a fan blade is fixedly connected to the side wall of the rotating rod extending into the filter barrel.

[0010] Preferably, the short rod is arranged between the fixing block and the fan blade, the second catalyst flow conduit is connected to the first catalyst flow conduit, and the surface of the stirring plate is provided with tiny holes.

[0011] Preferably, the scraper rod is arranged on the inner wall of the filter barrel.

[0012] Preferably, an ion membrane is fixedly connected to the interior of the box, and the ion membrane is arranged just above the filter barrel.

[0013] Preferably, a valve pipeline is fixedly connected to the other side of the box.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Through the setting of the assisting component, when feeding, the material will flow into the filter barrel through the valve pipe. Because the material is liquid, the flow rate of the material will drive the fan blades to rotate. During electrolysis, the stirring plate can achieve the stirring effect. In addition, during electrolysis, the catalyst can be injected into the rotating rod through a thin tube, flow through the second catalyst flow pipe and finally flow out from the tiny holes on the stirring plate. The advantage of this design is that stirring can be performed without the need for additional power. Secondly, during stirring, the catalyst will directly contact the material through the stirring plate, so that the use efficiency of the catalyst is maximized. By improving the use efficiency of the catalyst, the reaction process can be better controlled, purer products can be produced, the generation of by-products can be reduced, and the quality of the product can be improved.

[0016] 2. During electrolysis, the material is injected into the box from the valve pipe. At this time, the material will flow from bottom to top. The flow of the material from bottom to top can provide better material transfer and mixing effects, so that the catalyst and the material can be better contacted. This helps to improve the uniformity of the reaction, reduce the occurrence of incomplete reactions and side reactions, and thus improve the selectivity and yield of the reaction.

[0017] 3. When the electrolysis is in progress, the rotation of the rotating rod will drive the short rod to rotate together. At this time, the scraper rod attached to the inner wall of the filter barrel will make a circular motion around the filter barrel. The scraper rod will scrape the by-products produced during the electrolysis process from the filter barrel. This can prevent the by-products from clogging the filter barrel, resulting in the material in the filter barrel being unable to leave the filter barrel after the electrolysis is completed. The advantage of this design is that it can first prevent the by-products from clogging the ion membrane and avoid economic losses. Secondly, ensuring the permeability of the filter barrel can reduce the clogging and blockage of the filter medium and reduce the maintenance and cleaning frequency of the equipment, which reduces the production line downtime and maintenance costs and improves production efficiency.

[0028] The rotating rod 52 extends to the side wall at one end of the filter barrel 4 and is fixedly connected with a fan blade 57. When feeding, the material will flow into the filter barrel 4 through the valve pipe 3.
