Abstract
The utility model relates to agricultural water-saving irrigation equipment, belongs to the improvement of laminated filter lamination, particularly the special lamination of a kind of multistage netted filter in flow channel.Symmetrical and recessed annulus runner is being set respectively in the positive and negative card of circle ring disk, the positive and negative of circle ring disk are divided into respectively inner disc and outer disk by annulus runner, uniform respectively in the positive and negative card of circle ring disk radial ray is being set, wherein be positioned at the uniform column internal projection that arranging on the ray of inner disc card, be positioned at the uniform column outer lug that arranging on the ray of outer disk card, the height of column internal projection and column outer lug is 0.4-0.6mm.The utility model is rational in infrastructure, can make current flow resistance in lamination little, is not subject to obstructing of sand grain, and the loss of flood peak is little, and inflow-rate of water turbine is large, and filter efficiency is high, and backwash is convenient.
Description
Technical field
The utility model relates to agricultural water-saving irrigation equipment, belongs to the improvement of laminated filter lamination, particularly the special lamination of a kind of multistage netted filter in flow channel.
Background technology
Water-saving irrigation drip irrigation requires highly to water quality, will filter irrigation water in advance, prevents that dropper band from stopping up.And laminated filter is applied to the filter plant at drip irrigation water source just, laminated filter is particularly useful for filtering the surface water containing algae, and good filtration effect.
The core component of laminated filter is lamination, the plastics lamination upper and lower surface of laminated filter is carved with a large amount of longitudinally microchannels and is laminated in inner support, compress by spring and fluid pressure, the groove between lamination intersects, and forms the in-depth filtration unit of a series of unique filtration channels.When cascade filter work, current are from being flow to and entered lamination inside by lamination outward, and lamination compresses by spring and fluid pressure, and pressure reduction is larger, and lamination is pressed tightlyer, has formed lamination self-locking performance high efficiency filter.
The runner that its lamination of the laminated filter of promoting the use of at present arranges is above two kinds: one is line flowing channel, and runner quantity is few, and runner is long, and the loss of flood peak is larger, and inflow-rate of water turbine is little, and filter efficiency is low.One is netted runner, although runner quantity is many, is easily blocked by large particulate matter, and filter efficiency is low.
Utility model content
The purpose of this utility model is to be to provide the special lamination of a kind of multistage netted filter in flow channel, and it is rational in infrastructure, can make current flow resistance in lamination little, is not subject to obstructing of sand grain, and the loss of flood peak is little, and inflow-rate of water turbine is large, and filter efficiency is high, and backwash is convenient.
The purpose of this utility model is achieved in that the special lamination of a kind of multistage netted flow filter, symmetrical and recessed annulus runner is being set respectively in the positive and negative card of circle ring disk, the positive and negative of circle ring disk are divided into respectively inner disc and outer disk by annulus runner, uniform respectively in the positive and negative card of circle ring disk radial ray is being set, wherein be positioned at the uniform column internal projection that arranging on the ray of inner disc card, be positioned at the uniform column outer lug that arranging on the ray of outer disk card, the height of column internal projection and column outer lug is 0.4-0.6mm.
When the utility model work, when current enter laminated filter, current are to flow to lamination inside in the annular frame from supporting lamination, enter current in lamination can be from circle ring disk positive and negative the netted flow passage of two-stage of radial uniform columnar projections composition, the current after filtration flow in lamination.Lamination compresses by spring and fluid pressure, pressure reduction is larger, lamination is pressed tightlyer, formed lamination self-locking performance high efficiency filter, in addition, water passes through netted runner by lamination outer rim, water (flow) direction is not subject to the obstruction of sand grain and weakens conveyance capacity, current can flow through from columnar projections arbitrarily, and impurity is attached to the outer surface of lamination in addition, has formed good filter effect.The utility model is compared with normal lamination, and under identical condition of water quality, multistage netted runner is stronger than linear pattern runner and the netted runner conveyance capacity of single-stage, and the loss of flood peak is less than normal lamination.Due to netted runner of the present utility model, inflow-rate of water turbine is increased more than 50%.Therefore, the multistage netted runner easy cleaning of the utility model, anti-obstruction, the loss of flood peak is little, and inflow-rate of water turbine is large, and filter efficiency is high.The utility model is rational in infrastructure, has realized current flow resistance in lamination little, is not subject to obstructing of sand grain, and the loss of flood peak is little, and inflow-rate of water turbine is large, good filtration effect, and backwash is convenient.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is that master of the present utility model looks schematic diagram, the A-A sectional structure schematic diagram that Fig. 2 is Fig. 1.
Detailed description of the invention
The special lamination of a kind of multistage netted filter in flow channel, as shown in Figure 1 and Figure 2, symmetrical and recessed annulus runner 3 is being set respectively in the positive and negative card of circle ring disk, the positive and negative of circle ring disk are divided into respectively inner disc 1 and outer disk 2 by annulus runner 3, uniform respectively in the positive and negative card of circle ring disk radial ray is being set, wherein be positioned at the uniform column internal projection 2 that arranging on the ray of inner disc 1 card, be positioned at the uniform column outer lug 5 that arranging on the ray of outer disk 4 cards, the height of column internal projection 2 and column outer lug 5 is 0.4-0.6mm.The internal diameter of the inner disc 1 of circle ring disk is 90mm, and the external diameter of outer disk 4 is 150mm, and the thickness of circle ring disk is 0.3-04mm.Column internal projection 2 and column outer lug 5 form by cylinder or prism.Column internal projection 2 is cylinder, and its diameter is 0.35-0.45mm.Column outer lug 5 is cylinder, and its diameter is 0.55-0.65mm.Being positioned at adjacent ray spacing on inner disc 1 card internal diameter is 0.11-0.13mm.Annulus runner (3) degree of depth is 0.05-0.1mm, and width is 0.2-0.3mm.
