Description
Technical field
The invention belongs to water-saving irrigation technique fields, and in particular to a kind of double filtering anti-blocking drips of dual channel.
Technical background
Trickle irrigation is most scientific irrigation method, and core component of the water dropper as drip irrigation system, effect is to form head damage
It loses, pressure flow is made to enter water dropper energy dissipating, soil, water dropper water flow very little are instilled with stabilization, uniform low discharge, thus drip
Head apopore very little, generally only 0.7~1.1mm or so are easily blocked by dirt in water；In addition, drip irrigation system is poured water
Evenness depends primarily on the hydraulic performance of water dropper in addition to being influenced by system design.The superiority and inferiority pair of emitter structure and its hydraulic performance
Uniformity that drip irrigation system is poured water, anti-blockage capability, lifetime of system influence very big.And emitter structure largely determines
The superiority and inferiority of its hydraulic performance (in addition there are also manufacture deviations).
It is found simultaneously according to pre-stage test, emitter clogging accounts for more than half in the probability that water inlet blocks, so transformation is existing
There is the tunnel inlets pattern of water dropper necessary.
Labyrinth drip emitter flow passage structure is various informative in the market, and tooth form is different (sawtooth, straight-tooth, curved tooth and helical teeth), the most often
What is seen is zigzag, so the present invention focuses on improved zigzag labyrinth flow-path water dropper.
Summary of the invention
In view of the deficiencies of the prior art, the present invention proposes a kind of double filtering anti-blocking drips of dual channel.Double mistakes of the invention
The filter anti-blocking drip of dual channel can significantly improve its anti-clogging.
The object of the invention is implemented with the following technical solutions:
A kind of double filtering anti-blocking drips of dual channel, which is three-decker, from top to bottom successively includes flow channel layer, water inlet
Filter window layer and overhead filtering layer；The water inlet filter window layer and overhead filtering layer carry out double filtration to water flow, water can be made to flow into
The filter area for entering water dropper increases；
The flow channel layer includes two runners got through, the water catchment area of runner two sides and the diversion trench that communicates with runner
With stream storage area out.The design of the runner specifically: on the basis of zigzag labyrinth flow-path, first by the sawtooth of labyrinth flow-path
Form design is got through at fillet form, then by two runners.
In above-mentioned technical proposal, further, it is additionally provided between the water inlet filter window layer and overhead filtering layer aerial slow
Rush layer.
Further, the overhead filtering layer uses zigzag grid bottom, a kind of damping member that zigzag has made water dropper mostly
Element enhances damping.
Further, the grid is staggered " chevron ", makes grizzly bar direction and water flow angle at 45 °, upsets water
Water flow velocity is flowed into, blocking probability can be reduced.
The working principle of apparatus of the present invention is as follows:
Water flow is first by overhead filtering layer primary filtration, further filters into overhead buffer layer, then by water inlet filter window layer, into
Become a mandarin channel layer.There is height difference between water inlet filter window layer and flow channel layer, filters the filtered water of window layer through water inlet, be introduced into flow channel layer two sides
Water catchment area, then dual channel is entered by diversion trench and carries out turbulent energy dissipating.Last water flow, which collects in out, flows storage area, is gone out by the area
Stream.
The present invention has the advantages that
1. using two-passage labyrinth, blocking risk can be substantially reduced.Common labyrinth flow-path uses sawtooth on x, y-dimension
Shape, due to there is dozens of " angle ", it is easy to accumulate silt particles and generate blocking.Research finds that sawtooth runner is handled through fillet
Afterwards, the waterpower and performance of anti-blockage of water dropper are improved.On the basis of zigzag labyrinth flow-path, first by two labyrinth flow-paths of water dropper
Sawtooth form be designed to fillet form, then runner is got through, becomes smaller so that runner section regularly becomes larger, cross in fracture
Place, water flow achieve the purpose that energy consumption after mutually liquidating.Widened section is conducive to the silt washed away in runner, fillet simultaneously
More conducively guidance water flow forms whirlpool, to reduce blocking risk.
2. double filtration further decreases obstruction risk.Common water dropper patch is all made of unilateral (single) filter window water inlet
Mouthful, and the present invention is using double filtration.Setting overhead filtering layer collects first by water flow primary filter in overhead buffer layer
Afterwards, enter emitter flow channel after filtering using water inlet filter window layer.Double filtration is carried out using overhead filtering layer and water inlet filter window layer,
The filter area that water flow can be made to enter water dropper increases.So water inlet end increases filter area, and increases a heavy filtration, greatly
The big risk for reducing emitter clogging.
3. zigzag people's line grid bottom.Common emitter flow channel be on z-dimension it is flat, bottom surface and filter window grid be all flat
, do not generate the resistance of resistance or very little to water；Bottom surface (overhead filtering layer) is designed toothing by the present invention, keeps water dropper more
A kind of damping elements, enhance damping.
Meanwhile the grid at the common water dropper patch back side is parallel, and all with drip irrigation pipe water (flow) direction at right angle, makes mud
Husky particle is easy in water inlet hole plug；Grid is changed to staggeredly " chevron " by the present invention, makes grizzly bar direction and water flow at 45 degree of angles,
Upset water flow water inlet flow velocity, and blocking probability can be reduced.

Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
As shown in Fig. 2, a kind of double filtering anti-blocking drips of dual channel, which is three-decker, successively includes from top to bottom
Flow channel layer 4, water inlet filter window layer 1 and overhead filtering layer 5；The flow channel layer includes two runners got through 2, and the runner is set
Meter specifically: on the basis of zigzag labyrinth flow-path, the sawtooth form of labyrinth flow-path is first designed to fillet form, then by two
Runner is got through；The flow channel layer 4 is additionally provided with the water catchment area 8 of runner two sides and the diversion trench 7 that communicates with runner and goes out to flow
Storage area 3 (Fig. 1)；There are also overhead buffer layers 6 between the water inlet filter window layer 1 and overhead filtering layer 5；The overhead filtering
Layer 5 uses zigzag grid bottom, and the grid is staggered " chevron " (Fig. 3 and Fig. 4).
The working principle of apparatus of the present invention is as follows:
Water flow is first by 5 primary filtration of overhead filtering layer, filters the further mistake of window layer 1 into overhead buffer layer 6, then by water inlet
Filter, finally enters flow channel layer 4.It is filtered through water inlet filter window layer 1 due to having difference in height between water inlet filter window layer 1 and flow channel layer 4
Water is introduced into the water catchment area 8 of 4 two sides of flow channel layer, then carries out turbulent energy dissipating into dual channel 2 by diversion trench 7, and last water flow is collected
Going out stream storage area 3, is being flowed out by the area.
