Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a sewage treatment chemical dosing device. Background Art

[0002] A sewage treatment chemical dosing device is a device that treats sewage by reacting the chemical dosing device with harmful substances in the sewage to produce flocculants. Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. The chemical components of the chemicals for treating sewage are usually in the form of liquids and solid particles.

[0003] During the process of adding chemicals by the sewage treatment chemical dosing device, usually the chemicals are directly added to the upper end of the sewage, and then the chemicals are fully dissolved by a stirring device. When the chemicals are solid particles, during the adding process, the chemicals will first gather on one side, resulting in too high a chemical concentration on one side of the sewage and uneven dispersion, which makes the overall stirring time longer, thereby reducing the sewage treatment efficiency. Therefore, in view of the above problems, we propose a sewage treatment chemical dosing device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sewage treatment chemical dosing device to solve the problem that when the chemicals are solid particles, during the adding process, the chemicals will first gather on one side, resulting in too high a chemical concentration on one side of the sewage and uneven dispersion, which makes the overall stirring time longer, thereby reducing the sewage treatment efficiency.

The pharmaceutical particles enter the inside of the treatment tank 1 from the feeding port 3. The first electric telescopic rod 4 is started. The first electric telescopic rod 4 drives the sliding plate 6 to move left and right through the connecting plate 5, so that the sliding plate 6 drives the pharmaceutical particles to evenly fall on the turntable 12. Then the motor 9 is started. The motor 9 drives the turntable 12 to rotate slowly through the stirrer 10 and the connecting sleeve 11, so that the particles on the turntable 12 evenly fall into the sewage inside the treatment tank 1 from the discharge slot 13, reducing the excessive concentration of the pharmaceutical agent on one side caused by the accumulation of the pharmaceutical particles, making the concentration of the pharmaceutical agent in the sewage uniform, thereby reducing the overall stirring time and accelerating the sewage treatment efficiency.

[0021] Workflow: When in use, the device is powered by an external power supply. Sewage is discharged from the water inlet pipe 2 into the interior of the treatment tank 1, and then pharmaceutical granules are dropped from the feed inlet 3 onto the slide plate 6. At this time, the first electric telescopic rod 4 is started through the controller 14. The first electric telescopic rod 4 drives the connecting plate 5 to move left and right. The connecting plate 5 drives the limiting block 7 to move left and right along the sliding groove 8. The connecting plate 5 drives the slide plate 6 to move left and right, so that the pharmaceutical granules on the slide plate 6 slide down evenly onto the turntable 12. Then, the motor 9 is started through the controller 14. The motor 9 drives the stirrer 10 to rotate at a low speed. The stirrer 10 drives the connecting sleeve 11 to rotate at a low speed. The connecting sleeve 11 drives the turntable 12 to rotate at a low speed, so that the pharmaceutical granules on the turntable 12 are evenly scattered into the sewage from the discharge chute 13, thereby reducing the excessive concentration of the pharmaceutical on one side caused by the accumulation of pharmaceutical granules, making the concentration of the pharmaceutical in the sewage uniform, thereby reducing the overall stirring time and accelerating the sewage treatment efficiency. After the sewage treatment is completed, the valve on the water outlet pipe 17 is opened to discharge the sewage from the treatment tank 1. When the sewage in the treatment tank 1 splashes onto the turntable 12, causing the pharmaceutical granules to be wet and adhere to the discharge chute 13, the second electric telescopic rod 15 is started. The second electric telescopic rod 15 drives the brush assembly 16 to move upward, so that the upper end of the brush assembly 16 is in close contact with the lower end of the turntable 12. Then, when the turntable 12 rotates, the brush assembly 16 removes the adhered pharmaceutical, so as not to affect the next use.
