Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, and more specifically, to a rapid neutralization treatment device for chemical liquids. Background Technology

[0002] In recent years, with the rapid development of the global chemical industry, chemical products have been widely used in various fields, from daily necessities to high-end industrial materials. Chemical products are ubiquitous, greatly promoting economic growth and social progress. However, behind this prosperity lies a serious problem—the massive discharge of chemical waste. Chemical production processes are complex and diverse, involving numerous chemical reactions and processes. The resulting wastewater has extremely complex components, often containing high concentrations of acids, alkalis, heavy metals, organic matter, and various toxic and harmful substances.

[0003] High-concentration chemical waste liquids require rapid neutralization following the principle of "dilution buffering + step-by-step addition + forced mixing." This involves first controlling the reaction intensity and then precisely adjusting the pH to avoid hazardous reactions and secondary pollution. Existing neutralization devices typically use stirring to improve mixing efficiency. However, mechanical stirring can easily create relative flow during mixing, resulting in blind zones and low mixing quality. Therefore, we propose a rapid neutralization treatment device for high-concentration chemical waste liquids. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rapid neutralization treatment device for chemical liquids to solve the technical problems of low mechanical mixing efficiency and impact on neutralization quality.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rapid neutralization treatment device for chemical liquids, including an outer cylinder and an aeration device. The outer cylinder is provided with an inner cylinder. The upper end of the outer cylinder is provided with an end cap. The upper end of the end cap is provided with a drive assembly, and the output shaft of the drive assembly is connected to a rotating shaft on the lower side of the end cap. The rotating shaft is provided with stirring blades and a support. The aeration device includes a sleeve and a fixing ring fixed to the bottom of the inner cylinder, a turntable rotatably installed inside the fixing ring, an agitator cover sleeved inside the sleeve, and a rotating assembly connecting the agitator cover and the turntable. Both the agitator cover and the turntable are funnel-shaped, and there are interlocking teeth between the agitator cover and the turntable.

[0006] Preferably, an air inlet pipe is installed through one side of the outer cylinder, and the air inlet pipe connects the gap between the sleeve and the fixing ring. A discharge assembly is provided at the bottom of the outer cylinder, and the discharge assembly is connected to the lower pipe.

[0007] Preferably, a lower cylinder is fixed to the lower surface of the agitator cover, and the lower end opening of the lower cylinder is connected to the bottom opening of the sleeve through an aeration membrane. The aeration membrane is annular and has exhaust micropores.

[0008] Preferably, the lower surface of the oscillating cover and the upper surface of the turntable are both fixed with annular meshing teeth, and the tooth surfaces of the two meshing teeth mesh with each other. A spring is sleeved on the outside of the rotating assembly, and the upper and lower ends of the spring are fixed on the oscillating cover and the turntable, respectively.

[0009] Preferably, the rotating assembly includes an upper tube passing through the middle of the oscillation cover, a lower tube passing through the middle of the turntable, and a sealing sleeve that is fitted over the connection between the lower tube and the upper tube.

[0010] Preferably, the spring is located between the rotating assembly and the meshing teeth, the sleeve and the fixing ring are fixedly connected by a rod, and the agitator cover is in contact with the upper opening of the sleeve when closed.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The drive assembly of this utility model drives the lower tube to rotate through the rotating shaft and the bracket. The lower tube drives the turntable to rotate. The lifting and lowering of the agitator cover is completed by the interlocking of the meshing teeth. Together with the stirring blades, the liquid is stirred, so that the waste liquid flows in an irregular state, preventing the waste liquid from forming a specific flow direction during the stirring and mixing process, which would affect the mixing quality.

[0012] 2. The air inlet pipe of this utility model is connected to an external air supply device. Compressed gas is injected through the gap between the sleeve and the fixing ring. The compressed gas enters the cavity on the lower side of the aeration membrane. When the gas filling pressure increases, the aeration membrane is inflated, allowing the gas to be discharged upward through the pores on the aeration membrane. During the lifting and lowering of the agitator cover, the gas is discharged into the waste liquid in the inner cylinder through the gap. The gas-liquid contact is enhanced by the "bubble disturbance" of the compressed air. As the bubbles rise, they drive the surrounding waste liquid to flow, forming an "up and down circulation" liquid flow, allowing the neutralizing agent molecules to quickly diffuse into the entire waste liquid system, increasing the reaction contact area and ensuring the neutralization quality.
