Abstract
The utility model relates to a liquid filter used for filtration and pollution discharge, which is composed of a cylindrical casing, a cylindrical filter cartridge, a differential pressure controller, a steel brush, a discharging valve, a motor and a decelerator, wherein, a water inlet, a water outlet and a discharging outlet are arranged on the casing; the filter cartridge is arranged in the casing; the discharging valve adopts an electric discharging valve and is arranged on a discharging opening, the steel brush is connected with the motor by the decelerator, and the differential pressure controller is respectively electrically connected with the motor and the electric discharging valve. The liquid filter used for filtration and pollution discharge not only can realize water filtration, but also can automatically detect the stopping degree of the filter cartridge caused by contamination and automatically clean the contamination and impurity on the filter cartridge without manual intervention. Thus, the utility model is applicable to the pipes of various water systems.
Description
The utility model relates to a kind of liquid filter that is used for removal of contamination.
In water supply piping systems such as air-conditioning, heating, water for industrial use, owing to containing impurity and water in the water to Corrosion of Pipeline, so dirt and impurity are often arranged in the pipeline.Filter generally all is not set in water supply line at present, and dirt and impurity have corrosiveness to pipeline, and the water quality of the influence water that send; Also have in some water supply lines and adopt filter, in case and the filter inner product has impurity, just cause line clogging easily if do not clean, filter rinsed needs again manually filter to be pulled down cleaning, very trouble also need stop to send water, also is difficult to accomplish timely cleaning.
The purpose of this utility model provides a kind of also automatic filter that detects of water filtration that carries out by the chocking-up degree of dirt, the automatic dirt that is filtered, the full-automatic drain filter that need not manual intervention of cleaning.
The technical solution of the utility model is as follows: the utility model is by columniform housing, cylindric cartridge filter, the differential pressure controller that can utilize differential water pressures to control, be used to clean the steel brush of cartridge filter, blowoff valve, the motor and the decelerator that can drive steel brush rotary cleaning cartridge filter are formed, have water inlet on the housing, delivery port and the sewage draining exit that is used to get rid of dirt impurity, cartridge filter is arranged in the housing, blowoff valve adopts electronic blowoff valve and is arranged on the sewage draining exit to control the switching of sewage draining exit, steel brush links by decelerator and motor, and differential pressure controller is realized electrically connecting with motor and electronic blowoff valve respectively.
Blowoff valve also can adopt the electromagnetism blowoff valve, and its open and close controlling principle is similar to electronic blowoff valve.
Differential pressure controller is provided with two water inlet pipes that are used to measure hydraulic pressure, and one communicates with the water inlet of housing, and another root communicates with the delivery port of housing, so as by the sensor in the differential pressure controller measure before filtering hydraulic pressure with filter after the differential water pressures of hydraulic pressure.
The utility model is when operate as normal, water enters from water inlet, after the filter cylinder filtration, spill out from delivery port, the dirt of institute's filtering will be stayed on the cartridge filter, build up of dirt is to the filter mesh that to a certain degree will stop up on the cartridge filter, at this moment, hydraulic pressure before filtering will increase gradually, and the hydraulic pressure after the filtration will reduce gradually, and the differential water pressures that the pressure-controlled of being on duty device is measured before and after filtering reaches a certain setting value, differential pressure controller is starter motor and blowoff valve automatically, the driven by motor steel brush brushes down the dirt on the cartridge filter, and after blowoff valve was opened, water was discharged dirt from sewage draining exit.Hydraulic pressure before and after filtering restores balance again, automatic again disable motor of differential pressure controller and blowoff valve.The utility model recovers the water filtration duty again.
The utility model is not only realized the filtration of water; can also detect the filter opening of filter automatically by the chocking-up degree of dirt by differential pressure controller; automatically starting blowdown and sewage disposal apparatus when obstruction acquires a certain degree, crosses the reduction of leakage efficient; the obstruction dirt of cleaning and filtering tube; guarantee that filter keeps normal filtration duty; the automaticity height need not manual intervention, helps the timely cleaning and the protection equipment of filter.The utility model is widely used in hot water heating circulating system, the air conditioner water circulatory system, industrial water system and various cooling water recirculation system.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the Electricity Federation map interlinking of differential pressure controller in the utility model and motor, electronic blowoff valve;
Fig. 3 is the structural representation of one of the utility model embodiment;
Fig. 4 is two a structural representation of the utility model embodiment;
Fig. 5 is three a structural representation of the utility model embodiment.
Fig. 1 and Fig. 2 have reflected basic structure of the present utility model.Under normal circumstances, water enters the screen pack 2 of cartridge filter from the water inlet 6 of Fig. 1 bottom, filter after delivery port 7 flows out through filter cylinder, though between water inlet 6 hydraulic pressure P and the delivery port 7 hydraulic pressure P ' pressure reduction (P-P ') is arranged, but the pressure reduction of this moment is very little, a, c point in the differential pressure controller 4 of Fig. 2 links to each other but along with filter mesh is stopped up by dirt impurity gradually, differential water pressures increases; When differential water pressures increases to the setting differential pressure value that is set in differential pressure controller 4, the microswitch of differential pressure controller 4 is connected, its a, b point is linked to each other, then simultaneously starter motor 9 and electromagnetism blowoff valve (or electronic blowoff valve) 5, motor 9 rotates and drives steel brush 3 through decelerator 10, steel brush 3 rotates, and removes the dirt impurity that is attached on cylindric screen pack 2 inwalls, and dirt impurity is promptly gone out by water through blowoff valve 5; After dirt impurity is cleaned by steel brush 3, differential water pressures between the Inlet and outlet water of screen pack 2 front and back reduces, its microswitch of differential pressure controller 4 automatic disconnections, be 2 disconnections of a, b, and 2 of a, c join, then motor 9 stops operating, and blowoff valve 5 also is closed, and the utility model recovers normal water filtration duty.
Fig. 3 and Fig. 4 are three kinds of embodiments of the present utility model, unit number among the figure is corresponding identical with the unit number of Fig. 1, and internal structure is also identical, and just the installation site of water inlet 6, delivery port 7, motor 9, sewage draining exit 8 is different, profile is also different, is applicable to different water-system pipelines.The profile style that also may have other certainly.
