Description

Technical Field

[0001] The present invention relates to the field of preparing high-valent silver ion aqueous solution, and in particular to a device and method for preparing the silver ion aqueous solution. Background Art

[0002] Over a hundred years ago, silver-containing solutions were used as disinfectants. There are various methods for preparing silver-containing solutions, and chemical and physical methods such as dielectric reactions have been developed in recent decades. Although the preparation methods for silver-containing aqueous solutions have greatly improved in recent years, their purity remains unsatisfactory. Furthermore, the disinfection and sterilization capabilities and stability of silver-containing aqueous solutions produced under these conventional methods are somewhat limited, and they also have certain side effects during clinical use. The side effects of silver ion aqueous solutions, as well as the composition and stability of the solutions, are closely related to the preparation methods of the silver-containing aqueous solutions. These factors have seriously impacted the application and promotion of silver-containing aqueous solutions.

[0003] For related technology, reference can be made to patent application CN105750560B, which discloses a silver-containing antibacterial solution and its preparation method. The application comprises dissolving a silver salt component in deionized water to obtain a silver salt solution with a mass concentration of 0.001 to 10 g / l; dissolving a branched polyamine compound in deionized water to obtain a branched polyamine compound solution with a mass concentration of 0.01 to 50 g / l; and mixing the silver salt solution and the branched polyamine compound solution in a volume ratio of 1:1 to 1:100, stirring at 10 to 100°C for 1 to 180 minutes to obtain a stable silver-containing antibacterial solution. The stable silver-containing antibacterial solution is obtained by directly mixing the silver salt and the branched polyamine compound, which is simple to operate. The prepared silver-containing antibacterial solution has significant cationic properties and excellent adsorption properties for fiber materials. It also has excellent high-temperature resistance and light resistance, allowing for long-term storage. It also exhibits excellent salt, acid, and alkali resistance.

[0004] Regarding the above-mentioned related technologies, during the preparation process of the silver-containing solution, it is necessary to pay attention to the height difference between the electrode body and the liquid level. Different height differences will bring different reaction results, which will affect the implementation results. Therefore, there is an urgent need for a silver ion aqueous solution preparation device and preparation method to solve the above technical problems. Summary of the Invention

Then, according to the liquid level, the lifting cylinder is started. The lifting cylinder drives the lifting plate to move, thereby driving the two electrode bodies to move up and down, thereby changing the height difference between the liquid surface and the electrode body, ensuring the accuracy of the experimental process.

[0009] Optionally, the deionization component includes a deionization box, the upper end face of the deionization box is connected to a water inlet pipe, and a filter screen and ion exchange resin are horizontally arranged in the deionization box from top to bottom.

The driving wheel rotates, driving the driven wheel to rotate, and the active wheel is driven by the chain to rotate, thereby driving the threaded rod to rotate, so that the carrier box moves upward. When the filter is completely pulled out, the carrier box is located at the through hole, and then the staff lifts the ion exchange resin upward and takes out the ion exchange resin; when it needs to be reset, the ion exchange resin is replaced first, and then the replaced filter is reinserted to achieve reset. The replacement and cleaning of the ion exchange resin and the filter are realized through a through hole, reducing the original method of requiring multiple openings to remove the ion exchange resin and the filter. The structure is simple, the operation is simple, and it is conducive to improving work efficiency.

[0016] By adopting the above technical solution, when the fixing rod is inserted into the fixing hole, the fixing rod engages with the meshing wheel, driving the meshing wheel to rotate, thereby driving the bidirectional screw to rotate. The rotation of the bidirectional screw drives the two clamping rods to move, thereby pressing against the ion rod, providing a thrust to the ion rod in the horizontal direction, and further improving the connection stability between the ion rod and the fixing ring.

[0017] Optionally, a knob is provided on the lifting plate, and a connecting rod is provided inside the lifting plate. One end of the connecting rod is connected to the bidirectional screw through a bevel gear pair, and the other end is coaxially fixedly connected to the knob.

[0023] S4: Start the high-voltage power supply and adjust the power supply voltage through the transformer. When the AC voltage is greater than 10,000 volts, the air gap is broken down, and a luminous arc is generated between the electrode body and the water surface, causing a chemical reaction, thereby increasing the silver ion content in the water;

[0024] S5: As the process progresses, the length of the silver rod gradually shortens. The staff activates the lifting cylinder based on the value of the liquid level detector to adjust the distance between the electrode body and the water as needed to ensure the stability of the arc;

By setting the through hole, the carrying box, the threaded rod, the limiting rod, the driving wheel, the driven wheel and the handle, when the filter or ion exchange resin needs to be cleaned and replaced, the staff pulls the handle to drive the filter to slide out of the ion box. At this time, the rack on the filter is engaged with the driving wheel, thereby driving the driving wheel to rotate. The driving wheel rotates, driving the driven wheel to rotate, and the active wheel is driven by the chain to rotate, thereby driving the threaded rod to rotate, so that the carrying box moves upward.

The high-purity water enters the preparation box 21 from the deionization box 11, and the positive and negative electrodes of the high-voltage power supply are connected to the two connection terminals 263. The high-voltage AC power supply , electrode body - water - electrode body form a series circuit, and the liquid level height in the preparation box 21 is obtained through the liquid level detector 28, then the lifting cylinder 23 is started, and the height of the lifting plate 24 is adjusted, thereby adjusting the height difference between the electrode body 26 and the pure water in the preparation box 21 to make the height difference less than 4 cm, and the high-voltage power supply is started, and the power supply voltage is adjusted through the transformer. When the AC voltage is greater than 10,000 volts, the air gap is broken down, and a luminous arc is generated between the electrode body 26 and the water surface, and a chemical reaction occurs, thereby increasing the silver ion content in the water. Finally, the high-voltage power supply is turned off, and the water outlet valve 291 is opened to obtain the silver ion aqueous solution.
