Technical Field

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

[0002] Wastewater treatment is one of the important issues in environmental protection. During wastewater treatment, there are a large number of harmful substances in the wastewater, and these harmful substances cannot be removed by simple physical methods. At this time, it is necessary to add chemicals to the wastewater to react with these harmful substances to achieve the purpose of removing the harmful substances.

[0003] The amount of reagent added is closely related to the total amount of wastewater. At present, most of the reagents are added manually based on experience. Too much reagent will cause waste, and too little reagent will not guarantee the wastewater treatment effect. Therefore, a quantitative dosing device based on the amount of wastewater is needed.

[0005] As a preferred technical solution of the utility model, the dosing pipe valve is a solenoid valve, and a stirring mechanism is provided in the wastewater tank. The stirring mechanism includes a bottom motor, a rotating mounting plate, a mounting shaft and a spiral agitator. A bottom motor is installed at the bottom of the wastewater tank. This motor is connected to an external power supply and is equipped with a switch. A rotating mounting plate is rotatably installed at the center of the wastewater tank, which is driven by the bottom motor. The mounting shaft and the spiral agitator are fixed on the rotating mounting plate.

The other end is fixedly connected to the horizontal part of the U-shaped rod. The piston plate is made of rubber, and its outer wall is tightly fitted with the inner wall of the quantitative chamber. After adding wastewater to the wastewater tank, the buoyancy plate is in the buoyancy plate. Under the action of force, it is on the horizontal plane.

[0016] As a preferred technical solution of the utility model, the dosing pipe valve 72 is a solenoid valve, and the wastewater tank 1 is provided with a stirring mechanism. The stirring mechanism is provided to fully mix the agent and the wastewater and fully react. The stirring mechanism includes a bottom motor 101, a rotating mounting plate 102, a mounting shaft 103 and a spiral agitator 104.

[0017] As a preferred technical solution of the present invention, in order to avoid waste or insufficient materials, a quantitative structure is provided. Specifically, the quantitative structure includes an L-shaped connecting rod 8, a U-shaped rod 9, a buoyancy plate 10 and a piston plate 12. Two notches are opened on the top of the wastewater tank 1. Both ends of the U-shaped rod 9 extend into the wastewater tank 1 from the notches and the buoyancy plate 10 is fixed at the extending end. A notch is opened on the top of the quantitative chamber 6.
