Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a dosing device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of separating, removing, recycling, or converting pollutants in wastewater into harmless substances using various technologies and methods, so that the wastewater meets the water quality requirements for discharge into a water body or for reuse. This process typically includes physical, chemical, and biological treatment methods. Wastewater treatment dosing devices are important equipment in the wastewater treatment process; they are mainly used to add chemicals to wastewater to improve water quality, remove harmful substances, or increase water utilization.

[0003] Traditional wastewater treatment dosing systems have the following drawbacks: Because wastewater treatment is typically large-scale, while the coverage area of ​​the dosing system is relatively small, the mixing process between the chemicals and the wastewater becomes extremely lengthy. To ensure uniform dispersion of the chemicals in the wastewater, a significant amount of time is often required for stirring. This not only reduces wastewater treatment efficiency but also increases energy consumption and operating costs. Therefore, improvements are needed. Summary of the Invention

The rotating shaft 28 drives the disc 3 to rotate, and the disc 3 drives the block 4 to make a circular motion. The block 4 drives the rectangular plate 5 to move back and forth under the limit plate 29. The rectangular plate 5 drives the connecting rod 7 to move back and forth, thereby driving the dosing device 8 to move back and forth above the box 1. At this time, the water pump 17 transports the medicine mixed in the mixing tank 12 to the inside of the dosing device 8 through the hose 18, and then sprays it out through the nozzle 9 to add medicine to the inside of the box 1.

[0024] By activating the servo motor 27, the disc 3 drives the block 4 to move in a circular motion, thereby causing the dosing device 8 to move back and forth above the tank 1. At this time, the water pump 17 transports the mixed medicine in the mixing tank 12 to the inside of the dosing device 8 through the hose 18, thus adding medicine to the tank 1. Compared with the traditional dosing device for sewage treatment, this sewage treatment dosing device adds medicine by moving the dosing device 8 back and forth above the tank 1, thereby making the medicine evenly mixed with the sewage and improving the treatment effect.

[0025] Among them, cylinders 19 are fixedly installed on both sides of the box body 1, and telescopic rods 20 extending into the inside of the box body 1 are fixedly installed on the inner side of the cylinders 19.

The round rod 21 drives the connecting plate 22 to rotate, and the connecting plate 22 drives the stirring plate 23 to rotate, thereby stirring the inside of the box 1.

[0027] By activating cylinder 19, the cylinder 19 drives the telescopic rod 20 to move back and forth, causing the arc-shaped block 26 to move inside the arc-shaped groove 25, thereby driving the stirring plate 23 to rotate and thus stirring the inside of the tank 1. Compared with traditional sewage treatment dosing devices, this sewage treatment dosing device drives the stirring plate 23 to rotate through the connecting plate 22, thereby stirring the inside of the tank 1, thus improving the mixing efficiency of the drugs and improving the treatment effect.
