Abstract

The invention belongs to the technical field of filtration devices, and particularly relates to a constant-water-level filtration and back flush integrated device and a control method. The device comprises a filtration pool, a water storage tank and a constant-water-level filtration device. A filter material layer is arranged in the filtration pool. The constant-water-level filtration device is provided with a lower port, a middle port and an upper port from bottom to top. The lower port is connected with a filtration pool water outlet. The middle port is communicated with the water storage tank and is lower than the filtration water level of the filtration pool. The upper port is communicated with the upper space, higher than the filtration water level, of the filtration pool. The water storage tank is set as a closed space. A water drain pipe is arranged on the lower portion of the water storage tank. The constant-water-level filtration and back flush integrated device has the advantages that frequently-operative adjusting valves are not needed, constant-water-level filtration can be realized without data transmission, and backwashing of the filter material layer can be achieved effectively; the device is simple in structure, stable constant-water-level operation, energy conservation and environment protection are achieved, and filtering and backwashing integrated control can be also realized.

Description

Technical field [0001] The invention belongs to the technical field of filtration devices, and specifically relates to an integrated device and control method for constant water level filtration and backwashing. Background technique [0002] When the traditional V-shaped filter is working, the filter constant water level is controlled by the water outlet regulating electric valve, that is, when the traditional V-shaped filter is running in an automatic state, the built-in program of the controller will control the opening of the outlet valve according to the water inlet. In other words, if the water intake is large (small), the valve opening will increase (decrease) to keep the liquid level of the filter constant. In order to maintain this constant level value, as the liquid level in the filter tank changes, the electric valve for adjusting the water outlet needs to be opened or closed continuously, and such frequent opening or closing will cause great wear on the valve and actua...
