Description

A single-tank double-pump automatic dosing device

technical field

The utility model relates to the technical field of water treatment, in particular to a single-tank double-pump automatic dosing device.

Background technique

At present, in the field of water treatment, it is usually necessary to add chemicals to tap water, waste water or sewage to achieve the purpose of flocculation, descaling and disinfection. Calculate the ratio of the required concentration of the liquid medicine, and then add the medicine into the medicine dissolving tank, and carry out sufficient stirring and mixing. This dosing method is not only labor-intensive, but also the concentration of the liquid medicine is greatly affected by human factors. When the circulating water fluctuates, it is easy to cause insufficient or excessive medicine in the circulating water, which not only affects the effect of water treatment, but also wastes Pharmacy increases the operating cost of the enterprise. In particular, most of the medicaments are in the form of powder, which has certain toxicity or corrosiveness, and it is easy to fly when artificial feeding, polluting the environment, and easily causing harm to the physical and mental health of workers.
