Abstract
The utility model discloses a net type self counter flushing all plastic filter, which is suitable for the automatic filtration and elimination of dirt in water in a micro irrigation system. The utility model is composed of a shell (1), an end cover (2), a filter screen (4), water inlets (5) (5'), dirt discharging holes (7) (7') and a water outlet (6), etc., wherein, the filter screen (4) is divided into a left filter cavity and a right filter cavity, and the left and right filter cavity are respectively communicated with the water inlet (5), the dirt discharging holes (7), the water inlet (5') and the dirt discharging holes (7'). The utility model has no need to stop in the process of back flushing, the filter screen is not easy to block, and the utility model has the advantages of stable pressure, high irrigation quality, small volume, simple operation, high automation, easy control and high work efficiency.
Description
The utility model relates to the improvement of filter, and specifically a kind of net formula is applicable to the automatic fitration and the discharge of dirt in the water in the irrigation system course of work from the overall plastic filter of backwash.
Filter be used in the irrigation system dirt in the filtered water, prevent douche stop up, guarantee the to pour water key equipment of quality.At present, Chang Yong filter mainly contains with the sandstone and is the sandrock filter of filter medium and is the filter several types of filter medium with the filter screen.These filter mediums the phenomenon of dirt blocking filtering medium all can occur in filter process, when filter medium occurring and stopped up, the way that makes filter medium recover filtering function is to adopt backwash, even the current reverse flow.If be filter medium with the sandstone, when the water reverse flow is crossed each filter sand layer, particle thinner layer of sand in upper strata is under the effect of buoyancy and scouring force, volume expands, sand grains begins " becoming flexible ", spacing strengthens, the dirt that is trapped in is therebetween discharged by blowoff valve and blow-off pipe with current, and the water of discharge can recover to supply water to irrigation system after becoming clearly, filter for other filter mediums, also can adopt the backwash that uses the same method, make filter medium recover filtering function, but there is a significant disadvantages in this backwash: when water carries out backwash, must stop to supply water, influence irrigation efficiency to irrigation system.For irrigation system also can be supplied water to irrigation system in backwash process simultaneously, the employing that has is installed in parallel two identical filtering tanks at head pivot, the upper end of filtering tank is by the filtration and the backwash of three-way valve control water, when closing backwash tube, pressure flow enters collector pipe and sends into the irrigated area after filtering by water inlet pipe and two filtering tanks; During three-dimensional valve on closing one of them filtering tank, then opened the backwash tube of this jar simultaneously, the water of another filtering tank enters the irrigated area by a collector pipe part, another part flows to this jar and carries out backwash, dirt on this jar filter medium is got excited, discharge outside this filtering tank through backwash tube, become clear until flushing water, equally also can another filtering tank of backwash, the shortcoming that this back-flushing method exists is: filtering tank is in parallel to be used, strengthened and taken up room, volume is bigger, and is manual control, operation inconvenience, the control difficulty is big, inefficiency.
The purpose of this utility model be to provide a kind of not only overcome in the backwash process shut down low, the easy obstruction of flush efficiency, poor, the problem of low quality of pouring water of pressure stability, and overcome that volume is big, complicated operation, be difficult to control, a kind of net formula of ineffective problem is from the overall plastic filter of backwash.
The utility model is achieved in that this net formula is made of housing, end cap, the fastening card of sealing, screen pack, water inlet, delivery port, sewage draining exit from the overall plastic filter of backwash, screen pack is cylindric, the centre is provided with a water-stop sheet along axis, two filter chambers about screen pack is divided into, about two filter chambers be communicated with two water inlets, sewage draining exits respectively, water enters two filter chambers respectively by two water inlets, behind strainer filtering, enters pipe-line system by the filter delivery port.When right side filter chamber filter screen needs backwash, close the water intaking valve of right side filter chamber, open the blowoff valve of right side filter chamber simultaneously, water through left side filter chamber strainer filtering after, a filtered water part enters the irrigated area by the filter delivery port, another part back flush right side filter chamber filter screen, and discharge through right side filter chamber blowoff valve; When left side filter chamber filter screen needs backwash, close the left side filter chamber water intaking valve, open simultaneously the left side filter chamber blowoff valve, water through right side filter chamber strainer filtering after, a filtered water part enters the irrigated area by the filter delivery port, another part back flush left side filter chamber filter screen.This filter is also implemented by following measure: two water inlets insert aqueduct by entering water electromagnetic valve respectively, two sewage draining exits insert blow-off line by two blowdown magnetic valves respectively, side at housing is provided with the micro computer auto-controller, the micro computer auto-controller is connected with two blowdown magnetic valves with two entering water electromagnetic valves respectively by lead, flushing frequency during the flushing state, washing time, washing time all can be set arbitrarily according to irrigating environment, the micro computer auto-controller is controlled the duty of filtration system according to the operational factor of setting, and realizes the automation of filtration and backwash, sequencing.
The utility model has the advantages that: need not shut down in backwash process, filter screen is difficult for stopping up, pressure stability, and the quality of pouring water height, and also this filter volume is little, and simple to operate, the automaticity height, easy to control, high efficiency.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is the utility model partial schematic sectional view.
Make the utility model with reference to accompanying drawing 1.This net formula from the overall plastic filter of backwash by housing 1, end cap 2, seal fastening card 3, screen pack 4, water inlet 5, water inlet 5 ', delivery port 6, sewage draining exit 7, sewage draining exit 7 ' formation, screen pack 4 is cylindric, the centre is provided with a water-stop sheet 8 along axis, two filter chambers about screen pack 4 is divided into, a left side, right two filter chambers respectively with two water inlets 5,5 ' and sewage draining exit 7,7 ' be communicated with, two water inlets 5,5 ' by two entering water electromagnetic valves 9,9 ' respectively insert aqueduct 10,10 ', two sewage draining exits 7,7 ' by blowdown magnetic valve 11,11 ' respectively insert blow-off line 12,12 ', side at housing 1 is provided with micro computer auto-controller 13, micro computer auto-controller 13 by lead respectively with entering water electromagnetic valve 9,9 ' and blowdown magnetic valve 11,11 ' connect.When entering water electromagnetic valve 9,9 ' be subjected to the effect of micro computer auto-controller 13 to be in opening, and the effect of blowdown magnetic valve 11,11 ' be subjected to micro computer auto-controller 13 is when being in closed condition, water enters two chambeies of filter screen respectively, behind strainer filtering, enters the irrigated area by filter delivery port 6; When the obstruction of filter filter screen one chamber needs the blowdown backwash (as right chamber filter screen), micro computer auto-controller 13 just makes entering water electromagnetic valve 9 close, blowdown magnetic valve 11 is opened, the right chamber of the clean water backwash filter screen that gone out by left chamber strainer filtering this moment, the dirt that sticks to right chamber filter screen inwall is rinsed out, and it is by 11 discharges of blowdown magnetic valve, otherwise then as the same.
