Mixing technology in dosing device

 

Technical field:

A dosing device used in sewage treatment facilities. Specifically, it is the mixing device in the dosing device.

Background technology:

At present, the dosing device being used in the sewage station is mainly composed of mixing device and storage device, which are widely sold in the market.

Mixing device generally includes mixing motor, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer, high transmission ratio reducer High transmission ratio, high transmission ratio, high transmission ratio, high transmission ratio, high transmission ratio, high transmission ratio, high transmission ratio, high transmission ratio, high transmission ratio, high transmission ratio and high transmission ratio.

For a long time, in the sample of environmental protection equipment company, the rated power of the mixing motor is usually far greater than the power required for actual mixing in various sizes, specifications and dosing devices in use. The low power factor of the motor leads to low efficiency of large horses and small cars. The main reason is that the industry designers have been used to compare the motor power with the motor power of the same size and specification, and determine the motor power of the newly designed products according to the idea of re-amplification.

After the dosing device is installed in the sewage station, the water pipe needs to be led to the upper port of the dosing device. During operation, the dosing dose shall be calculated according to the required configuration concentration. First, add the required amount of coagulant into the mixing tank, then open the tap water faucet, add tap water into the mixing tank, and close the water to the liquid level proportion line on the mixing tank. Then turn on the mixing motor to drive the blades for mixing. After mixing evenly, all of them are discharged into the medicine storage tank of the medicine storage device, and then the next cycle is carried out, waiting for the next discharge into the medicine storage tank; The liquid medicine provided in the medicine storage tank is output to the unit required by the sewage treatment facility through the metering pump.

From the working process of its mixing device, there are four operating processes, namely: dosing, water addition, mixing and liquid discharge. First add medicine, then add water and then add water. The solid coagulant is stacked at the bottom of the mixing tank, and the water is covered at the top, which is not conducive to mixing. Mixing drugs and water takes a long time, usually 50-70 minutes.
