CN101822920A - Self-cleaning filter - Google Patents

Abstract

The invention relates to a self-cleaning filter, which mainly comprises a controller and a case, wherein the controller consists of an embedded microprocessor, a program control circuit and an LCD human-computer interface circuit, the case mainly comprises a cleaning mechanism, a sewage flow guide opening, a cleaning brush, a sewage suction pipe, a filtering screen, a box body, a sewage discharge valve, a water inlet opening and a water outlet opening, and the controller is connected with the case through a connecting circuit. During operation, water enters a pump body through the water inlet opening, is then filtered through the filtering screen, and is next discharged from the water outlet opening, during filtration, the filtering screen is cleaned in time by the cleaning brush, and fouling products, impurities and visible sand grains can be discharged through the sewage suction pipe and the sewage discharge valve. The invention does not need to stop the work of a water supply system and does not need the manual intervention in the filtering and sewage discharge process, and has the characteristics of clean brushing cleaning, fast sewage discharge and the like.

Summary of the invention

Technical problem solved by the invention is to provide self-cleaning filter, to solve the shortcoming in the above-mentioned background technology.

Technical problem solved by the invention realizes by the following technical solutions:

Self-cleaning filter, mainly comprise controller and housing, described controller is made up of embedded microprocessor, sequence circuit, LCD man-machine interface circuit, described housing mainly comprises wiper mechanism, sewage flow-guiding mouth, cleaning brush, dirt sucking tube, screen pack, casing, blowoff valve, water inlet, delivery port, and described controller links to each other with housing by connecting circuit.During operation, water enters the pump housing by water inlet, filters by screen pack then, is discharged by delivery port again, and when filtering, cleaning brush is in time cleared up screen pack, and by dirt sucking tube and blowoff valve fouling product, impurity and the visible grains of sand is discharged.

In the present invention, the RS232 on the described controller RS485 or USB interface can be connected with PC or other intelligence systems, realize Long-distance Control.

In the present invention, the water quality monitoring sensor is housed in the described housing, can continual monitoring water quality.

In the present invention, the top of the wiper mechanism of described housing is motor, the bottom of wiper mechanism is an axis, the top of axis is provided with the sewage flow-guiding mouth, and a plurality of cleaning brush and dirt sucking tube are housed on the axis, and the outside of axis is that screen pack is equipped with in the center of circle with the axis, axis stretches in the casing, one side on casing top is equipped with blowoff valve, and the bottom of casing is provided with water inlet, and a side of casing is provided with delivery port.

Beneficial effect:

The present invention filter, in the blowdown process, characteristics such as the work that need not stop water system also need not manual intervention, has to scrub clean, and blowdown is rapid.
