Description

Automatic cleaning system of water tank for water quality measuring instrument

The present invention relates to an automatic cleaning device for a water tank for a water quality measuring instrument, and more specifically, a sampling inflow pipe through which water for sampling and an overflow pipe through which overflow water is discharged are coupled to the upper part, and an instrument outflow valve The combined instrument outlet pipe and the drain outlet pipe to which the drain outlet valve is combined are coupled to the bottom, and consist of two water tanks of the same type equipped with a floater scraper that moves up and down according to the water level by being in close contact with the inner wall surface. The present invention relates to an automatic water tank cleaning device for a water quality measuring instrument capable of continuous water quality measurement even during cleaning because the water tank is automatically cleaned and alternately made.

Generally, a water tank device for measuring water quality is a device that stores water of a well well as a sample water in a water tank by a pump or natural hydraulic pressure, and measures the properties of the water quality of the sample water.

In more detail, it is a water tank used in a tele-monitoring system (TMS), which receives sample water through a pump of a well and measures the properties of the sample water with a measuring device and an analyzer installed in the water tank, so that the drug is injected. It is a device that can do it.

The interior of the water tank of the water tank device for measuring water quality is not designed to consider the flow of fluid, and scum is generated at the top due to the influence of chemicals, sediments are formed at the bottom, and foreign matter is attached to the wall surface, resulting in errors in water quality analysis. And shortening the cleaning time interval, and there is the inconvenience of removing foreign substances only through frequent water tank cleaning.

The cleaning of the water tank is different depending on the turbidity flowing into the water tank, but it should be performed once or twice a week, and if the cleaning is delayed, the accuracy of water quality analysis decreases, and there is a problem of overdosing and small amount of chemicals.

In addition, since the cleaning of such a water tank must be performed frequently by manpower, the economic cost increases, the cleaning time is long, and water quality measurement is impossible for about 1 hour before and after cleaning.
