AI Technical Summary

Problems solved by technology

There are different degrees of "pollution" in the water tank for secondary water supply during use, such as the growth of microorganisms, red worms and accumulated impurities, etc.
In fact, the value of the pressure difference before and after the filter is very small, especially in the case of flow rate, it is difficult to accurately provide a backwash signal for the filter by detecting the pressure difference
Moreover, backwashing too frequently is a waste of water resources, and backwashing too late will lead to low water supply pressure

Embodiment 1

[0010] Example 1, such as figure 1 As shown, the water tank filter monitoring device of the present invention has a judging controller 1, which is installed outside the water tank 4, and the output end of the judging controller 1 is connected with the water pump electric switch of the filter 5, and the luminescent tube 2 and the photosensitive Pipe 3 is installed on the transparent plastic pipe water inlet pipe 6 of filter 5, and is electrically connected with judging controller 1. The luminescent tube 2 and the photosensitive tube 3 can also be installed in the water inlet pipe, and the water inlet pipe is a non-transparent pipe. In order for the water supply unit to grasp the usage of each water tank, a telephone line or network line 8 is connected to the judging controller 1, and the detected parameters are sent to the water supply unit so that the water supply unit can determine whether the water tank should be cleaned.

[0011] The judging controller 1 of the water tank ...

Embodiment 2

[0012] Example 2, such as figure 2 As shown, the water tank filter monitoring device of the present invention can also be installed in the water tank, and its connection relationship is the same as that of embodiment 1. Luminescent tube 2 and photosensitive tube 3 also can be installed outside water inlet pipe certainly.

Abstract

A monitor system for the filter of water tank to control the back flush of filter is composed of the luminous tube and photosensitive tube installed before the water inlet of filter, a judging controller electrically connected to said luminous and photosensitive tubes, a water pump, and the switch of said water pump and connected to the output of said controller.

Description

technical field [0001] The invention relates to a monitor and control device for a water supply tank filter. technical background [0002] During the peak and low peak periods of urban water supply, the water pressure of the pipe network varies greatly, resulting in abnormal water supply to high-rise buildings, especially high-rise sections. In order to ensure the water supply to high-rise buildings, water storage tanks are built on the top or bottom of the building to ensure stable water supply pressure, which is the so-called secondary water supply. The water tank for secondary water supply has different degrees of "pollution" during use, such as the growth of microorganisms, red worms and accumulated impurities. In order to prevent "polluted" domestic water from flowing into residents' homes, it is common practice to install a filter at the outlet of the water tank. When the dirt in the filter accumulates to a certain extent, the filter is backwashed, and then the dirt ...
