Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment, specifically to a stirring device for treating tin-containing wastewater. Background Technology
[0002] A stirring device for treating tin-containing wastewater is a specialized piece of equipment. Its main function is to mechanically agitate the tin ions in the wastewater to thoroughly mix with a precipitant, forming a water-insoluble precipitate. This precipitate is then separated from the water through filtration or precipitation. This device plays a crucial role in industrial wastewater treatment. Chinese patent discloses a stirring device for treating tin stripping wastewater (authorization announcement number CN 219922807). This patented technology utilizes a rotating motor to drive a connecting rod and a gear, which in turn rotates a meshing gear that drives a connecting rod. The connecting rod then rotates the stirring rod, straight scraper, and L-shaped scraper, thus mixing and blending the materials. The straight and L-shaped scrapers remove residue from the inner wall of the casing, reducing material buildup and simplifying manual cleaning. When the straight and L-shaped scrapers need to be disassembled or replaced, they can be removed from the stirring rod using mounting bolts and mounting plates, increasing the device's flexibility and convenience. However, this design suffers from poor stirring performance, and the tin-containing wastewater forms insoluble precipitates after the chemical reaction, as no filtration structure is provided. Therefore, those skilled in the art have developed a stirring device for treating tin-containing wastewater to address the problems mentioned in the background section. Utility Model Content

The filter device is installed on the lower side of the stirring tank, and the filter box is installed inside the filter device. The rotating shaft is installed inside the stirring tank, and the paddle agitator is installed in the middle of the rotating shaft. The turbine agitator is installed at the upper and lower ends of the paddle agitator. The first scraper is installed at the upper end of the inner side of the stirring tank, and the second scraper is installed at the lower end of the inner side of the stirring tank. The third scraper is connected to the second scraper.
[0004] Preferably, the bottom of the mixing tank is provided with a conical funnel, the upper side of the mixing tank is provided with a liquid inlet and a material inlet, and a valve port is installed on the lower side of the mixing tank, with a valve installed inside the valve port;

[0007] The technical effects and advantages of this utility model are as follows:
[0008] 1. Installing a paddle agitator can generate strong shear force and axial thrust, so that the mixture can be fully mixed in a short time and achieve a uniform mixing effect. Installing turbine agitators at both the upper and lower ends of the paddle agitator can generate highly turbulent radial flow during rotation. This flow mode helps to enhance mass and heat transfer, thereby efficiently blending the mixture and improving the efficiency of chemical reaction.
[0009] 2. The filter box can filter the solution, leaving the precipitate inside. The solution flows down through the filter holes and is discharged from the drain port. The filter box can be removed from the filtration device for cleaning and the addition of filter materials such as filter membranes to improve the filtration quality. Attached Figure Description
