Through the cooperation of the stirring assembly and the spraying cooling circulation system, the temperature of the electrode rod and the liquid around the electrode rod is well reduced, and the electrolytic processing benefit is improved.

Description

Technical Field

[0001] This invention relates to the field of electrolytic cell equipment technology, and in particular to a diaphragm electrolytic cell with a spray cooling circulation system. Background Technology

[0002] A Chinese patent with publication number CN218262773U discloses a cooling device for an electrolytic cell. The device includes a cell body, a diaphragm, an anode rod, and a cathode rod, as well as a cover plate disposed on top of the cell body; an agitation mechanism for agitating the liquid within the cell; a cooling mechanism for cooling the cell body; the agitation mechanism includes a pair of agitator shafts rotatably mounted within the cell body; and a drive device for driving the agitator shafts to rotate within the cell body. During electrolysis, the cooling mechanism operates to cool the cell body, and the agitation mechanism operates to agitate the liquid within the cell body, ensuring uniform cooling of the liquid.

[0003] The above-mentioned solution only involves agitating the surrounding liquid by stirring the anode and cathode rods with a stirring shaft to prevent the hot liquid from continuously cooling the area around the anode and cathode rods. Instead, it allows the cooler liquid from other areas to flow to the area around the anode and cathode rods, thus achieving a simple cooling effect. However, as the working time increases, the liquid temperature in the tank will become higher, and the cooling effect achieved by stirring alone will be poor. Further improvement and optimization are needed.

Detailed Implementation

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figures 1-14 A diaphragm electrolyzer with a spray cooling circulation system includes an electrolyzer body 1 and a support leg 2 disposed at the bottom of the electrolyzer body 1. An inlet 3 and a outlet 4 are respectively disposed at both ends of the electrolyzer body 1. A diaphragm assembly 6 is disposed in the cavity of the electrolyzer body 1. A stirring assembly is disposed at the bottom of the electrolyzer body 1 and the electrolyzer body 1 is connected to the spray cooling circulation system. An electrode rod 5 is disposed at the top of the electrolyzer body 1 and the spray cooling circulation system cools the electrode rod 5.

[0021] This design, on the one hand, uses the stirring motor 801 to drive the stirring blades 803 to stir the liquid in the electrolytic cell body 1, preventing the hot liquid around the electrode rod 5 from accumulating for a long time. Furthermore, a spray cooling circulation system is installed in conjunction with the stirring assembly to cool the electrode rod 5. Through the cooperation of the circulation pump assembly 905, the annular pipe 901, and the liquid extraction port 902, the hot liquid around the electrode rod 5 is extracted. The liquid is then cooled by a cooling auxiliary mechanism. An ion separator 909 is installed at the end of the liquid extraction port 902, which further cools the liquid during extraction. During liquid circulation cooling, active ions in the liquid are blocked to prevent them from being lost with the liquid. Finally, the liquid is sprayed onto the electrode rod 5 through a spray mechanism to cool the electrode rod 5 and the surrounding high-temperature liquid. The stirring assembly includes a stirring motor 801, a connecting shaft 802, and stirring blades 803. The stirring motor 801 is fixedly installed at the bottom of the electrolytic cell body 1 and is connected to the connecting shaft 802. The connecting shaft 802 extends through and into the inner cavity of the electrolytic cell body 1, and the end of the connecting shaft 802 is provided with stirring blades 803.

[0022] While the liquid in the electrolytic cell body 1 is stirred by the stirring assembly, the spray cooling circulation system also operates simultaneously. When extracting liquid from the electrolytic cell body 1, multiple annular tubes 901 are equidistantly arranged around the electrode rod 5, and multiple liquid extraction ports 902 are provided inside the annular tubes 901. The purpose is to directly extract the liquid with higher temperature around the electrode rod 5. The extracted liquid enters the storage tank 907, and is then cooled by the cooling auxiliary mechanism in the storage tank 907. Finally, it enters the inner cavity of the electrolytic cell body 1 and is cooled by the spray head 1 inside the annular spray pipe 1002. The 003 system sprays and cools the liquid, which then flows back into the main body 1 of the electrolytic cell. It also cools the liquid around the electrode rod 5. The spray cooling circulation system includes an annular pipe 901, a liquid extraction port 902, a connecting pipe 903, a support pipe 904, a circulation pump assembly 905, a connecting pipe 906, a storage tank 907, a return pipe 908, an ion separator 909, a spray mechanism, and a cooling auxiliary mechanism. The annular pipe 901 is equidistantly arranged on one side of the connecting pipe 903, and the liquid extraction port 902 is equidistantly arranged on the inner side of the annular pipe 901. The connecting pipe 903... A support pipe 904 is provided on the side, with one end extending to the outside of the electrolytic cell body 1. The end of the support pipe 904 is connected to a circulation pump assembly 905, which is also connected to a connecting pipe 906. The other end of the connecting pipe 906 is located at the top of a storage tank 907, which contains a cooling auxiliary mechanism. A return pipe 908 is located at the bottom of the storage tank 907, with one end at the top of the electrolytic cell body 1 and the other end extending into the inner cavity of the electrolytic cell body 1. The return pipe 908 within the inner cavity of the electrolytic cell body 1 is connected to the spray system. The mechanism is connected; the annular tube 901 is arranged around the side of the electrode rod 5, and the opening of the liquid extraction port 902 faces the electrode rod 5; the spraying mechanism includes a guide tube 1001, an annular spray pipe 1002 and a spray head 1003; one end of the guide tube 1001 is connected to the return pipe 908, and the bottom end of the guide tube 1001 is connected to the annular spray pipe 1002. Spray heads 1003 are equidistantly arranged on the inner wall of the annular spray pipe 1002; the annular spray pipe 1002 is also arranged around the side of the electrode rod 5, and the annular spray pipe 1002 is located above the topmost annular tube 901.

[0023] The extracted liquid enters the storage tank 907 and is primarily cooled by the cooling branch pipe 1106. The cooling auxiliary mechanism includes a mounting cavity 1101, a mounting plate 1102, a coolant inlet 1103, a coolant outlet 1104, a manifold 1105, the cooling branch pipe 1106, and auxiliary accessories. The mounting cavity 1101 is located on one side of the storage tank 907 and has threaded holes. The mounting plate 1102 is fitted into the mounting cavity 1101 and secured with screws. A manifold 1105 is fixedly installed on the inner side of the plate 1102, and cooling branch pipes 1106 are fixedly installed at equal intervals on the side wall of the manifold 1105. A coolant inlet 1103 and a coolant outlet 1104 are provided on the outer side of the plate 1102. Both the coolant inlet 1103 and the coolant outlet 1104 are connected to the manifold 1105. That is, the extracted liquid enters the storage tank 907 through the connecting pipe 906, is cooled by the cooling branch pipes 1106, and then flows back to the inner cavity of the electrolytic cell body 1 through the return pipe 908 at the bottom of the storage tank 907.

[0024] To further improve the cooling effect of the cooling branch pipe 1106 on the liquid, on the one hand, coolant is introduced through the coolant inlet 1103, then flows through the manifold 1105 and the cooling branch pipe 1106, and finally flows out from the coolant outlet 1104 on the other side of the mounting plate 1102. The coolant introduced through the coolant inlet 1103 creates a flowing cooling effect on the cooling branch pipe 1106, carrying away the heat from the liquid entering the liquid storage tank 907. On the other hand, under long-term cooling operation, to ensure the cooling performance of the cooling branch pipe 1106, i.e. Over prolonged use, scale may form on the surface of the cooling branch pipe 1106. This scale formation negatively impacts the cooling effect of the cooling branch pipe 1106. Therefore, this solution utilizes auxiliary accessories to clean the scale on the cooling branch pipe 1106. These accessories include a cleaning collar 1201, an auxiliary scraper ring 1202, a receiving rod 1203, a loading groove 1204, a positioning slot 1205, a loading ring body 1206, a positioning protrusion 1207, a cleaning brush 1208, and a connecting cap 120. 9; A cleaning collar 1201 is fitted onto the cooling branch pipe 1106, and an auxiliary scraper ring 1202 is provided at one end of the cleaning collar 1201. Adjacent cleaning collars 1201 are fixedly connected by a supporting rod 1203. The number of sets of cleaning collars 1201 and cooling branch pipes 1106 is the same, and one cleaning collar 1201 is fitted onto one cooling branch pipe 1106. A loading groove 1204 is provided on the inner side of one end of the cleaning collar 1201, and positioning slots 1205 are symmetrically arranged in the loading groove 1204. The loading ring body 1206 is adapted to fit in the loading groove 1205. The loading ring 1206 is placed in the loading slot 1204. A positioning protrusion 1207 is symmetrically fixed at one end of the loading ring 1206. The positioning protrusion 1207 and the positioning slot 1205 are positioned correspondingly and are fitted together. A cleaning brush 1208 is arranged in a ring shape on the inner side of the loading ring 1206. A connecting cover 1209 is attached to one end of the cleaning collar 1201 and is fixed by screws. The number of loading rings 1206 and cleaning collars 1201 is the same. One loading ring 1206 is placed in one cleaning collar 1201.

[0025] During cleaning, first remove the mounting plate 1102, then remove the cooling branch pipe 1106. Next, pull the cleaning collar 1201 to allow the auxiliary scraper ring 1202 on the front of the cleaning collar 1201 to scrape away the scale on the surface of the cooling branch pipe 1106. Simultaneously, the cleaning brush 1208, located on the inner side wall of the loading ring 1206, also provides a cleaning effect on the surface of the cooling branch pipe 1106. That is, after the auxiliary scraper ring 1202 removes the scale from the surface of the cooling branch pipe 1106, if any fine residue remains, it can be cleaned again by the cleaning brush 1208. After cleaning, the cooling branch pipe 1106 is then... During installation and use, the cleaning collar 1201 needs to be slid back to its initial position, i.e., near the manifold 1105. During prolonged use, the cleaning brush 1208 also needs to be cleaned to ensure its cleanliness and thus its ability to clean the cooling branch pipe 1106. The loading ring 1206 is placed in the loading groove 1204 at one end of the cleaning collar 1201, and is initially positioned by the engagement of the positioning protrusion 1207 with the positioning slot 1205. Removing the loading ring 1206 means removing the cleaning brush 1208, i.e., placing the loading ring 1206 back into the loading groove 1204. After initial positioning, the loading ring 1206 is limited by the connecting cap 1209. Specifically, the connecting cap 1209 is tightly fitted to the end of the cleaning ring 1201 with the loading groove 1204, and fixed with screws. This achieves the installation and fixation of the loading ring 1206, thus completing the installation of the cleaning brush 1208. Therefore, when cleaning the cleaning brush 1208 is required, it can be cleaned according to the actual situation. For example, when it is necessary to disassemble the loading ring 1206 to clean the cleaning brush 1208, the cleaning ring 1201 is slid off the cooling branch pipe 1106, and the exposed cleaning brush is directly cleaned. Cleaning 1208 is sufficient; if cleaning is difficult or a new cleaning brush 1208 needs to be replaced, first, the connecting cover 1209 needs to be removed. After removing the connecting cover 1209, the loading ring 1206 can be taken out from the loading slot 1204. After cleaning the cleaning brush 1208, it can be installed by placing the loading ring 1206 in the loading slot 1204 and making the positioning protrusion 1207 at one end of the loading ring 1206 engage with the positioning slot 1205 in the loading slot 1204. Finally, the connecting cover 1209 can be installed and fixed to limit the loading ring 1206.

[0026] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
