Self-control water-saving device for inflow water of filter tank

Abstract

The invention relates to a self-control water-saving device for inflow water of a filter tank, belonging to the technical field of energy conservation of filter tanks. The self-control water-saving device comprises a sewage lifting pipe, a high-position water inlet distribution box and a water inlet header pipe, wherein the water inlet header pipe led out from the bottom of the high-position water inlet distribution box communicates with a siphon ascending pipe of a siphon backwashing device in a clear water area of the filter tank; the siphon backwashing device comprises a siphon ascending pipe and a siphon drainage pipe, and the tops of the siphon ascending pipe and the siphon drainage pipe are connected into a whole; an inflow water controller is arranged on the water inlet header pipe; a falling water monitoring sensor is arranged on the siphon drainage pipe; the inflow water controller and the water falling monitoring sensor are in signal communication with a control system; and the control system is in signal connection with air extraction equipment of the siphon backwashing device. The device can accurately judge siphon formation, automatically open an air extractor and close a valve on the water inlet header pipe, promote rapid vacuumizing in the last stage of filtering to form backwashing, save a large amount of flushing water, save a large amount of electric energy for improving water inlet, and produce considerable comprehensive benefits and economic benefits.

Description

Technical field [0001] The present invention belongs to the field of energy saving technology, in particular, refers to an improvement in self-control energy saving for conventional automated hydraulic siphon filters. Background technique [0002] The traditional siphon filter includes a valve filter and a valve filter, which are composed of a filter, an inlet device, and a siphon-absorbent flushing device. During the filtration process, the water level in the siphon is increased, When the water level rises to the top of the siphon pipe tube, when the siphon drain is entered, the sink is produced, and the water filter material is quickly washed with the water filter material in the liquid filter area. When the liquid level in the water area is lower than the sink When destroying, the siphon destroying tube is inhaled to damage the entire siphon action, so that the anti-washing ends. [0003] During the operation of the siphon filter, no matter the filtering or the backwashing sta...

Problems solved by technology

In actual operation, the disadvantage of this device is: when the sensor detects that there is water in the transparent tube, it cannot confirm that the siphon has formed. At this time, it only sends out a false signal. Only when there is drainage in the siphon discharge pipe, it indicates that the siphon has formed. If the control system receives a false signal and cuts off the water intake prematurely, the water level in the siphon ascending pipe will not rise again, and the water level has just reached the top transparent pipe, and no siphon phenomenon occurs, and the backwash cannot be started
