Description

Technical Field

[0001] This utility model relates to the field of high-purity sodium hydroxide solution preparation technology, specifically a stirring and neutralizing device for high-purity sodium hydroxide solution. Background Technology

[0002] High-purity sodium hydroxide solution is a strongly alkaline solution with high corrosiveness. Due to its unique chemical properties, it has wide applications in many fields. High-purity sodium hydroxide solution has a strong pungent odor and can react chemically with many substances. Its strong alkalinity allows it to neutralize acidic substances, so it is often used as an acid-base regulator in chemical experiments and industrial production. By adding high-purity sodium hydroxide solution to a solution, acidic substances can be neutralized, raising the pH value of the solution to neutral or alkaline. For example, in industrial wastewater treatment, sodium hydroxide reacts with acidic wastewater to produce salt and water, thereby reducing the corrosiveness and pollution of the wastewater. To improve the efficiency of high-purity sodium hydroxide solution preparation, a stirring and neutralization device is needed. However, existing stirring and neutralization devices still have the following shortcomings:

[0003] When using existing mixing and neutralizing devices, most of them have solution residue in the tank after production, which requires regular cleaning. However, existing cleaning methods are mostly chemical cleaning or manual disassembly and cleaning. In addition, the cleaning structure of existing mixing and neutralizing devices is mostly fixed, which makes the overall cleaning time-consuming and labor-intensive, increases the labor intensity of workers, and causes problems such as reduced practicality and efficiency of the mixing and neutralizing device.

[0004] The purpose of this invention is to provide a stirring and neutralizing device for high-purity sodium hydroxide solution to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-purity sodium hydroxide solution stirring and neutralization device, comprising a main tank and a cleaning component. A support frame is installed at the lower outer end of the main tank. A cleaning component is arranged on the right side of the main tank. The cleaning component includes a mounting base, a hydraulic cylinder, a mounting top plate, a water supply pipe, a connecting pipe, a docking ring, a mounting docking groove, a rubber sealing ring, an annular water pipe, and an atomizing nozzle. A hydraulic cylinder is installed at the upper end of the mounting base, and a mounting top plate is installed on the top of the hydraulic cylinder. A water supply pipe is installed on the lower left side of the mounting top plate. A connecting pipe is distributed at the front end of the water supply pipe.

[0009] Furthermore, the stirring assembly includes a mounting top cover, an inspection cover, a servo motor, and a support rod. An inspection cover is provided on one side of the mounting top cover, and a servo motor is installed in the middle of the upper end of the mounting top cover, with a support rod connected to the front end of the servo motor.

[0010] Furthermore, the mixing assembly also includes a spiral mixing ring, a metering pump, mounting rods, and mixing components.

[0013] This invention provides a stirring and neutralization device for high-purity sodium hydroxide solution, which has the following beneficial effects:

[0014] 1. This utility model, through the setting of the cleaning component, enables the hydraulic cylinder to move the mounting top plate during the use of the high-purity sodium hydroxide solution stirring and neutralization device.

The atomizing nozzle 310 and the annular water pipe 309 are embedded. The atomizing nozzles 310 are vertically distributed and equidistantly distributed at the lower end of the annular water pipe 309. The mounting base 301 is fixed to the outside right side of the main tank body 1 using fastening bolts. The hydraulic cylinder 302 is also fixed to the upper end of the mounting base 301 using the same fastening bolts. The operation of the hydraulic cylinder 302 moves the mounting top plate 303, thereby adjusting the position of the water supply pipe 304 installed on the lower left side of the mounting top plate 303. The internal dimensions of the water supply pipe 304 are compatible with the external dimensions of the connecting ring 306 added to the outside of the connecting pipe 305. After the water supply pipe 304 and the connecting pipe 305 are connected and installed, the connecting ring 306 increases the stability and sealing during installation.
