Description
Technical field
The utility model relates to the device that fluid media (medium) that pipeline is carried filters.Specifically be a kind ofly can realize simultaneously that the impurity in the fluid medium carries out the automatic cleaning strainer of rotational flow separation, surface interception, in-depth filtration.
Background technology
Existing disk type automatic cleaning strainer all is to be combined by several filter elements.Each filter element is to be made of unit housings, plough groove type disc, reversal nozzle and reversal valve etc.But owing on structural design, make it in application, exist unfavorable problem.High and need shut down when maintenance as complex structure, maintenance rate, pipeline can not guarantee normal for defeated medium.When needing to clean filter cake through working long hours, filter do not guarantee needs for defeated pressure and flow.Therefore say that existing discal filter is not very desirable in actual applications.
Summary of the invention
At above-mentioned situation; the utility model provides a kind of and can need not shut down; guarantee that pipeline normally just can keep in repair for failing under the medium situation, change filter element, and when instead cleaning impurity automatically, also can guarantee to supply the disk type pipeline filter of defeated pressure medium and stability of flow.To solve the practical problem that existing equipment in use exists.And reversal valve and filter element housing seat are the design of one, make structure simple more compact, and the operation safety and reliability is overhauled more convenient.
The utility model structure is as shown in drawings: partly be made of suction line, filter element group, blowdown pipeline, outlet line etc.One spare filtering cell is arranged in the filter element group.Between suction line and each filter element, have inlet and cut valve.Have bypass in the bottom of suction line and cut valve.Have outlet between outlet line and the filter element and cut valve.One coarse strainer is arranged in suction line.One backwash jet pipe is arranged in the filter element housing.At backwash jet pipe outer cover sabot sheet post.On the tube wall of backwash jet pipe, have opening.The opening place has the non-return sheet.On jet pipe wall, have tangential spray orifice.The clamping sleeve that one spring assist is arranged in backwash jet pipe upper end.The clamping sleeve spiral-lock is pressed on the disc post on flushing jet pipe top and seat.The top of backwash jet pipe has relief hole.In the filter element lower housing portion one valve body is arranged.Be provided with tangent line eddy flow passage in inboard, medium inlet, unit.In eddy flow passage front one diaphragm valve valve port is arranged, there is an inlet diaphragm at the valve port place, and there is a spring base diaphragm inboard, has spring on the spring base.At tangent line eddy flow passage rear side one blowdown barrier film valve port is arranged, there is a sewage draining exit diaphragm at the valve port place, and there is a spring base sewage draining exit diaphragm inboard, has spring on the spring base.The utility model is furnished with electric control gear and pressure source distributor, is used for monitoring medium transport pressure and flow.And command each position to make corresponding action.
Method of work of the present utility model is: when being filtered medium under pipeline self pressure, flowed into by filter inlet, after the coarse strainer coarse filtration, enter suction line.Cut valve through shunt pipeline and inlet, medium inlet, unit on each filter element valve body enters valve body again, at this moment, inlet diaphragm rebounds under the pressure of medium, open the barrier film valve port at this point, the medium of this moment forms eddy flow during by the eddy flow passage and enters between the disc post on filter element housing and the backwash jet pipe, sewage draining exit diaphragm inboard pressurising under the effect of pressure source pressure at this moment.Blowdown barrier film valve port is blocked.The medium of eddy flow wherein large granular impurity gets rid of on the filter element inner walls by its centrifugal force.Form the first road rotational flow separation.Medium will wherein be blocked in the table of disc post greater than the impurity of disc groove in by the disc post.Enter the disc groove together less than the impurity of disc groove and the medium that is filtered, and collision cohesion mutually in groove, be blocked once more, form in-depth filtration.Medium because the non-return sheet at opening place is pushed in the pressure effect open, enters in the backwash jet pipe after filtering by three kinds of forms.Flow into outlet line through the unit media outlet again, enter again in the defeated pipeline.Finish filter process.Behind filter work certain hour, each filter element disc post forms filter cake and blocks when circulating behind surface and in-depth filtration, occur pressure differential between the entrance and exit.At this moment, electric control gear sends instruction.By distributor, command that each filter element is counter respectively to clean blowdown.Because this device has spare filtering cell, devotes oneself to work automatically during anti-the cleaning.When the import and export that the filter element that is overhauled the time is closed in maintenance cut valve, spare filtering cell is put into operation, therefore can guarantee the normal and continuous operation of filtration system.And pressure and flow for defeated medium remain unchanged.Filter element is anti-when cleaning under the commander of electric control gear and pressure source distributor, the filter element medium inlet is closed in the inboard punching press of inlet diaphragm, the inboard pressure release of the diaphragm valve of blowdown is simultaneously opened sewage draining exit, medium reverse flow or other pressure source reverse media in the outlet line flows in the backwash jet pipe chamber at this moment, because the effect non-return sheet of pressure is blocked opening, reverse media stream can only spray to the disc post through tangential spray orifice.Because the pressure source medium is tangential ejection, so formation eddy flow, drive the disc reverse rotation, simultaneously since between filter element housing and the disc post pressure and backwash spray intraluminal pressure and pressure reduction occurs, so clamping sleeve is loosened, disc is washed open under eddy flow, the filter cake carried secretly in the disc groove and the filter cake on disc post surface are washed out together, and discharge along sewage draining exit simultaneously with the impurity on the filter element inner walls.The utility model is simple in structure, and is reasonable in design, do not have pressure and flow loss when maintenance and anti-the cleaning, can normal operation, and be a kind of desirable pipeline automatic cleaning filter.
