Technical Field

The application relates to the technical field of tap water scale removal and inhibition, in particular to a liquid mixing device.

Background

Tap water is used as domestic water and is popularized in the lives of residents in cities and rural areas. Scale in tap water can cause great harm to users, and the harm is as follows:

1. the poor heat conductivity of the water scale can cause the heat transfer condition of the heating surface to be worsened, thereby wasting fuel or electric power;

2. scale, if attached to the heated surface of a thermal device, can compromise the safe and economical operation of the thermal device. Because scale has poor thermal conductivity, heat transfer is hindered. The heat absorbed by the furnace tube from the flame side can not be well transferred to water, and the cooling of the furnace tube is influenced, so that the wall temperature rises, the furnace tube is expanded, and the tube explosion is caused;

3. when the scale is cemented, a large amount of heavy metal ions are often attached, and if the container is used for containing drinking water, the risk that the heavy metal ions are too much dissolved in the drinking water exists; and

4. the scale fragments entering the stomach react with hydrochloric acid to release calcium and magnesium ions and carbon dioxide, which are necessary substances for calculus formation. The latter can be a source of flatulence and discomfort, and gastric ulcer patients may also be at risk of gastric perforation.

Therefore, before the water is used by the residents, the tap water needs to be subjected to operations such as descaling and scale inhibition, and then is supplied to the residents for use.
