Abstract
An automatic backwash filter with dual filter screens and a filtration method are disclosed. A traditional filtration product has the shortcomings of small pollutant holding quantity, easy clogging by dirt, disassemble cleaning of the filter parts and failure to monitor filter status, and does not have the function of automatic filtering of raw water, automatic cleaning of filter core or pollution discharge; and interrupted water supply of the system during cleaning and pollution discharge cannot effectively monitor the operating status of the filter, and the filter does not have high degree of automation. The automatic backwash filter with dual filter screens comprises a stationary base (1), a filter cylinder (3) and an upper capping (7). The stationary base is connected with the filter cylinder; and the filter cylinder is connected with the upper capping. The filter and the filtration method can be applied to filtering apparatus.
Description
Technical field:
The present invention relates to a kind of filtration and belong to indispensable process means in water purification process, for intercepting the impurity in water, to purify water or the normal operation of other equipment in protection system.
Background technology:
Filter, it is a kind of utilize filter screen directly to intercept the impurity in water, remove water body recovery technology, particulate matter, reduce turbidity, purify water, minimizing system dirt, bacterium algae, corrosions etc. produce, to purify water and the precision equipment of other equipment normal operation of protection system, the pollutant holding capability of traditional filtering product is little, it is subject to dirt blocking, filtration fraction needs disassembly, cleaning and cannot numerous shortcomings such as monitor filter state, and not there is the function former water being filtered and filter element cleaning blowdown automatically automatically, and clean system interruption water supply during blowdown, the duty of filter be can not get effective supervision, automaticity is not high.
Summary of the invention:
It is an object of the invention to provide a kind of double filter screen full-automatic back washing filter and filter method.
Above-mentioned purpose is realized by following technical scheme:
A kind of double filter screen full-automatic back washing filter, its composition includes: firm banking, cartridge filter, upper cover, and described firm banking is connected with described cartridge filter, and described cartridge filter is connected with described upper cover.
Described double filter screen full-automatic back washing filter, water inlet, outlet, pressure difference switch, control piper are installed outside described cartridge filter, described water inlet is connected with described cartridge filter bottom, described outlet is connected with described cartridge filter top, described pressure difference switch is connected with the control piper of monologue story-telling with gestures, described cartridge filter is internally installed coarse strainer, fie screen, suction nozzle, filter screen baffle plate, 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 filter screen full-automatic back washing filter, is separately installed with joint difficult to tackle, blowoff valve outside described upper cover, described blowoff valve is connected with electromagnetic valve, and described upper cover is internally installed hydraulic motors, and described water conservancy motor is connected with described suction nozzle.
On described double filter screen full-automatic back washing filter, described fie screen and described coarse strainer, all processing has one group of circular hole, and described suction nozzle is staggered form suction nozzle.
The filter method of described double filter screen full-automatic back washing filter, after the method comprises the steps: that water flows through filter cartridge filtration, 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 cuts out, when blowoff valve is opened, current are forced to enter outside cartridge filter from the inducer mesh of cartridge filter, major part flows out from outlet, a part enters inside cartridge filter through impurity collection section mesh again outside filter, cartridge filter is created backwash, reach to stick to the effect of impurity mesh from outside flushing of cartridge filter, impurity is discharged yet by sewage draining exit.
Beneficial effects of the present invention:
1. the present invention has the function former water being filtered and filter element being carried out blowdown automatically, and when cleaning blowdown, system uninterruptedly supplies water, and has automaticity height compared with conventional filter, treating capacity is big, can self-cleaning blowdown, and uninterruptedly supply water, the advantages such as application surface is extensive, cleaning way is simple, control mode is versatile and flexible, can realize automatically cleaning blowdown, even if influent quality occurs bigger wave propagation system automatically to adapt to, process.
The present invention utilizes filter screen directly to intercept the impurity in water; remove water body recovery technology, particulate matter; reduce turbidity; purify water; minimizing system dirt, bacterium algae, corrosion etc. produce; to improve water quality and to protect the equipment of other equipment normal operation, because of its good filtration effect, resistance is little and is widely used in the fields such as water source filtration, industrial circulating water system
3. the present invention adopts hydro powered, saves the energy, is more suitable for the occasion not easily powered, and filtering accuracy is defaulted as 50 microns, and optional from 10 microns to 3000 microns, and precision is high, and filter area is big, and pollutant holding capability is high, and user can customize according to actual condition.Adopting actively cleaning way, the intensity suction produced on suction nozzle during cleaning makes cleaning more thorough, the equal scalable of each parameter in control system.
The present invention has the feature that uninterruptedly supplies water, need not bypass when cleaning blowdown, and scavenging period is short, and blowdown water consumption is few, maintainability is strong, installing/dismounting is simple and easy to do, easy and simple to handle, it is not necessary to professional is operated instructing.
The connected mode of the present invention and user's pipeline is Flange joint, and flange adopts GB flange, highly versatile.Can be effectively protected environment, simultaneously can also by reach after sewage disposal can the standard of reuse, be so possible not only to solve a difficult problem for sewage discharge, it is possible to realize recycling and provide cost savings.
