Background
In a plurality of water treatment projects, in order to improve the water quality, powder medicaments or granular microbial agents are often added into water at regular time and quantity. The original adding mode is that an operator measures a certain amount of medicament, then a small amount of water is added, the mixture is uniformly stirred by a stirrer and then added into a water tank, or the mixture is added into a water treatment pipeline by a high-pressure metering pump.
The pressure in the water pipeline is 0.3-0.5Mpa, so the metering pump must be more than 0.6Mpa to add the medicament into the pipeline system. Some powder medicaments are low in dissolving speed or some hard medicaments are insoluble in water, so that the abrasion of wading parts of the metering pump and the dosing device is rapidly accelerated, and the service life of the dosing device is shortened. In particular, in a microcrystalline soft water treatment facility, a hard water-insoluble crystal nucleus particle needs to be added into a water conveying pipeline running under pressure in a timed and quantitative mode.
