Abstract
The utility model aims to provide an automatic lamination filtering system. The automatic lamination filtering system provided by the utility model comprises a two-position three-way valve, and the automatic lamination filtering system is characterized in that the two-position three-way valve comprises a water inlet, a water outlet and a drain outlet; the water inlet is communicated with a water inlet pipe, the water outlet is communicated with a lamination filtering unit, a drain outlet is communicated with a discharge pipe, and the lamination filtering unit is also communicated with a water outlet pipe. The automatic lamination filtering system provided by the utility model is mainly used for filtering agricultural irrigation water (spray irrigation water and trickle irrigation water).
Description
Technical field
The utility model relates to a kind of filtration system, relates in particular to a kind of automatic laminating filtration system.
Background technology
Present stage laminated filter operation and backwash all adopt manual control valve to realize, and some systems even adopt the mode of full manual cleaning, compare labor intensive, and automaticity is also lower.The utility model is exactly to use full-automatic laminated filter unit, adopts two-position three-way valve to substitute common manually-operated gate, to realize automatic fitration and the automatic back-washing of laminated filter unit.
The needs of existing laminated filter in order to realize automatic fitration, to move continuously, also can adopt multiple-unit parallel form, but the connection valve of each unit or employing are manually controlled, or adopt two-way electronic valve door to realize automatic fitration and backwash, but valve quantity is many, control complexity, cost is high, operating difficulties.
Summary of the invention
The purpose of this utility model is to provide a kind of automatic laminating filtration system, to overcome above-mentioned shortcoming.
For achieving the above object, solution of the present utility model is: a kind of automatic laminating filtration system, comprise two-position three-way valve, it is characterized in that: described two-position three-way valve 3 comprises water inlet 7, delivery port 8 and sewage draining exit 9, water inlet 7 is communicated with water inlet pipe 4, delivery port 8 is communicated with laminated filter unit 1, and sewage draining exit 9 is communicated with blow-off pipe 5, and laminated filter unit is also communicated with outlet pipe 6.
The beneficial effects of the utility model are:
Traditional laminated filter is owing to adopting manually-operated gate or electrically operated valve to realize continuous filtration, automatic back-washing, relatively labor intensive materialization, automaticity is not high, another manually or electrically operated valve opening time long, control more complicated, backwash water consumption is large, fault rate is also higher, and the utility model replaces common manually-operated gate by adopting control system to control two-position three-way valve, automatic fitration and the automatic back-washing of laminated filter unit have been realized, saved water, protected environment, the environmental pollution of having avoided external application backwash water to bring, also improved efficiency simultaneously, improved working condition.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model (during normal filtration).
Fig. 2 is the structural representation of the utility model (during backwash).
In figure: 1-laminated filter unit, 2-Pressure gauge, 3-two-position three-way valve, 4-water inlet pipe, 5-drainpipe, 6-outlet pipe, 7-water inlet, 8-delivery port, 9-sewage draining exit.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model and the specific embodiment thereof are described in further detail.
Referring to Fig. 1-2, the utility model comprises two-position three-way valve, it is characterized in that: described two-position three-way valve 3 comprises water inlet 7, delivery port 8 and sewage draining exit 9, water inlet 7 is communicated with water inlet pipe 4, delivery port 8 is communicated with laminated filter unit 1, sewage draining exit 9 is communicated with blow-off pipe 5, and laminated filter unit is also communicated with outlet pipe 6.
Pending sewage flows into water inlet pipe 4 by pumping for water pump, by two-position three-way valve 3, flows to laminated filter unit 1, under the centrifugal pan effect of current in laminated filter unit, forms centrifugal effect.By crossing filter core outside, flow to filtration in-core side, current are when the passage of the ring-type rib formation through laminate surface, outside particle diameter in sewage is intercepted at while being greater than rib height, what have is stored in the space that curve rib forms, filters water afterwards and flow to outlet pipe 6 by filtering core inner.Automatic laminating filtration system, has two kinds of modes to start filter system backwash function, and the first is set working time and washing time by controller.The second by pressure difference switch signal transmission to system controller, while surpassing setting value due to the pressure differential of water inlet pipe and outlet pipe, by pressure difference switch to controller signals.By controller, send pulse signal, controlling the sewage draining exit 9 of two-position three-way valve opens, water inlet 7 is closed, the laminated filter unit that current direction water inlet after laminated filter unit by another in work is filtered is closed is by its backwash, the pressure of backwash water is greater than the pressure into water, filter core in filter element flicks, and lamination and then unclamps in suspended state.Form tangent line current and promote lamination High Rotation Speed.The various foreign material particles that laminate surface is piled up are rinsed totally, and discharge by the sewage draining exit 9 of two-position three-way valve.Each laminated filter unit carries out backwash successively, all the other filter element normal filtration, and system can provide the water after clean filtration all the time.Lamination after cleaning recovers impaction state under spring action, reenters filtration duty.
