Cartridge filter top connects, and the pressure difference switch is connect with the control piper told a story, and coarse filtration is equipped with inside the cartridge filter
Net, fie screen, suction nozzle, strainer baffle, the coarse strainer are connect with the strainer baffle, the strainer baffle with it is described
Fie screen connection.
The back purge system of described automatic filter core cleaning blowdown, be separately installed with outside the upper capping connector difficult to tackle,
Blowdown valve, the blowdown valve are connect with solenoid valve, and hydraulic motors, the water conservancy motor are equipped with inside the upper capping
It is connect with the suction nozzle.
The back purge system of the automatic filter core cleaning blowdown, the fie screen on the coarse strainer with processing
There is one group of circular hole, the suction nozzle is staggered form suction nozzle.
The filter method of the back purge system of the automatic filter core cleaning blowdown, this method comprises the following steps：Flow
It after the filtering of filter cylinder, is discharged by outlet, after blowdown valve station is opened, is increased by filter liquid total flow, flow velocity increases
Greatly, it has got excited the impurity being sticked on filter tube wall, impurity is discharged by sewage draining exit, when switching valve is closed, and blowdown valve is opened, water
Stream is forced to enter on the outside of cartridge filter from the inducer mesh of cartridge filter, most of to be flowed out from outlet, and a part is again outside filter
Portion enters through impurity collection section mesh inside cartridge filter, and backwash is produced to cartridge filter, reaches to rinse outside cartridge filter and glue
The effect of impurity on mesh is attached to, impurity is discharged yet by sewage draining exit.
Beneficial effects of the present invention：
1. the present invention has the function of to be filtered raw water and carries out cleaning blowdown to filter core automatically, and system during cleaning blowdown
Uninterrupted to supply water, with high degree of automation with previous filter compared with, treating capacity is big, can self-cleaning blowdown, not between
The advantages that cut-off water, application surface is extensive, cleaning way is simple, and control mode is versatile and flexible, it can be achieved that clean blowdown automatically, even if
Larger wave propagation system, which occurs, for influent quality to adapt to automatically, handled.
2. the present invention directly intercepts the impurity in water using strainer, removal water body recovery technology, particulate matter reduce turbidity, only
Change water quality, reduce the generations such as system dirt, bacterium algae, corrosion, to improve water quality and the equipment that other equipment is protected to work normally, because
Its good filtration effect, resistance are small and are widely used in the fields such as water source filtering, industrial circulating water system,
3. the present invention uses hydro powered, energy saving, it is more suitable for being not easy the occasion powered, it is micro- that filtering accuracy is defaulted as 50
Rice, and it is micron optional from 10 microns to 3000, precision is high, and filter area is big, and pollutant holding capability is high, and user can be according to actual condition
Customization.Using active cleaning way, the intensity suction generated on suction nozzle during cleaning makes cleaning more thorough, each ginseng in control system
Number is adjustable.
4. the present invention has the characteristics that uninterruptedly to supply water when cleaning blowdown, need not bypass, and scavenging period is short, blowdown consumption
Water is few, maintainability is strong, installing and dismounting is simple and easy to do, easy to operate, and Operating Guideline is carried out without professional.
5. the present invention and the connection mode of user's pipeline are flanged joint, flange uses national standard flange, versatile.It can be with
Environment is effectively protected, while can also will reach after sewage disposal and so can not only be solved with the standard of reuse
The problem of sewage discharge, can also realize that recycling saves cost.
