Description

Double layer filter high efficiency sewage backwash filter and filter method
Technical field:
Belong to indispensable processing means in the purification process of water the present invention relates to a kind of filtering, for intercepting the impurity in water, with purify water or protection system in other equipment normal work.
Background technology:
Filter, it is a kind of impurity that utilization filter screen is directly intercepted in water, removal water body recovery technology, particulate matter, reduce turbidity, purify water, reduction system dirt, bacterium algae, corrosion etc. is produced, with purify water and protection system other equipment normal work precision equipment, the pollutant holding capability of traditional filtering product is small, easily blocked by dirt, filtration fraction needs disassembly, cleaning and cannot numerous shortcomings such as monitor filter state, and without being filtered to raw water and the automatic function of being cleaned blowdown automatically to filter core, and system interruption supplies water during cleaning blowdown, working condition to filter cannot get effective monitoring, automaticity is not high.
The content of the invention:
It is an object of the invention to provide a kind of double layer filter high efficiency sewage backwash filter and filter method.
Above-mentioned purpose is realized by following technical scheme:
A kind of double layer filter high efficiency sewage backwash filter, its composition includes:Firm banking, cartridge filter, upper capping, described firm banking are connected with described cartridge filter, and described cartridge filter is connected with described upper capping.
Described double layer filter high efficiency sewage backwash filter, water inlet, delivery port, pressure difference switch, control piper are installed outside described cartridge filter, described water inlet is connected with described cartridge filter bottom, described delivery port is connected with described cartridge filter top, described pressure difference switch is connected with the control piper told a story, coarse strainer, fie screen, suction nozzle, filter screen baffle plate are installed inside described cartridge filter, described coarse strainer is connected with described filter screen baffle plate, and described filter screen baffle plate is connected with described fie screen.
Described double layer filter high efficiency sewage backwash filter, joint difficult to tackle, blowoff valve are separately installed with outside described upper capping, described blowoff valve is connected with magnetic valve, and hydraulic motors are provided with inside described upper capping, and described water conservancy motor is connected with described suction nozzle.
Described double layer filter high efficiency sewage backwash filter, one group of circular hole is machined with described fie screen and described coarse strainer, and described suction nozzle is staggered form suction nozzle.
The filter method of described double layer filter high efficiency sewage backwash filter, the method comprises the following steps:After water flows through filter cartridge filtering, discharged by outlet, after blowoff valve station is opened, increased by filter liquid total flow, flow velocity increases, get excited the impurity being bonded on filter tube wall, impurity is discharged by sewage draining exit, when switching valve is closed, when blowoff valve is opened, current are forced to enter cartridge filter outside from the inducer mesh of cartridge filter, and most of to be flowed out from outlet, a part enters inside cartridge filter from outside filter through impurity collection section mesh again , Backwash is generated to cartridge filter , The effect rinsed from cartridge filter outside and stick to impurity on mesh is reached, impurity is discharged yet by sewage draining exit.
Beneficial effects of the present invention:
1. The present invention has the function of being filtered to raw water and to filter core clean blowdown automatically, and system uninterruptedly supplies water during cleaning blowdown, has high degree of automation compared with conventional filter, treating capacity is big, can self-cleaning blowdown, and uninterruptedly supply water, the advantages of application surface is extensive, cleaning way is simple, control mode is versatile and flexible, automatic cleaning blowdown is capable of achieving, even if influent quality occurs larger wave propagation system and can also adapt to automatically, is processed.
The present invention directly intercepts the impurity in water using filter screen; removal water body recovery technology, particulate matter; reduce turbidity; purify water; reduction system dirt, bacterium algae, corrosion etc. are produced; equipment to improve water quality and protection other equipment normal work, the fields such as water source filtering, industrial circulating water system are widely used in because of its good filtration effect, resistance is small
3. The present invention uses hydro powered, energy saving to be more suitable for being difficult the occasion of power supply, and filtering accuracy is defaulted as 50 Micron, and from 10 Micron is extremely 3000 Optional, the high precision of micron, filter area is big, and pollutant holding capability is high, and user can customize according to actual condition.Using active cleaning way, the intensity suction produced on suction nozzle during cleaning makes cleaning more thorough, and each parameter in control system can adjust.
The present invention has the characteristics of uninterruptedly being supplied water when blowdown is cleaned, need not bypassed, and scavenging period is short, and blowdown water consumption is few, maintainability is strong, installing/dismounting is simple and easy to do, easy to operate, and Operating Guideline is carried out without professional.
, with the connected mode of user's pipeline for flange is connected, flange is using GB flange, highly versatile for the present invention.Environment can be effectively protected, while will can also be reached after sewage disposal the problem of sewage discharge so can not only be solved with the standard of reuse, can also realize that recycling saves cost.
