Abstract
The utility model relates to agricultural water-saving irrigation equipment, which belongs to an improvement for the laminate structure of a laminate filter, and particularly relates to a multi-stage composite laminate for a laminate filter. According to the multi-stage composite laminate, oblique-line-shaped flow channels which are radially and uniformly distributed are formed in the front disc surface and the back disc surface of an annular disc respectively; the cross sections of the oblique-line-shaped flow channels are V-shaped; the intersection angles of the oblique-line-shaped flow channels and the diameter of the annular disc are 14-16 degrees; annular flow channels which are concentrically ringed are uniformly formed in the front disc surface and the back disc surface of the annular disc respectively; and the oblique-line-shaped flow channels are separated by the annular flow channels. The multi-stage composite laminate disclosed by the utility model is multiple in filter stages, multiple in the flow channels, short in the flow channels, easy to clean, anti-blockage, less in head loss, high in excess flow, and high in filter efficiency.
Description
Technical field
The utility model relates to agricultural water-saving irrigation equipment, belongs to the improvement of laminated filter lamination, particularly a kind of lamination filter multistage composite lamination.
Background technology
The water-saving irrigation drip irrigation will be filtered irrigation water in advance to the requirements in water quality height, prevents the drip irrigation zone obstruction.And the lamination filter is applied to the filter plant at drip irrigation water source just, and the lamination filter is particularly useful for filtering the surface water that contains algae, and good filtration effect.
The core component of laminated filter is lamination, the plastics lamination upper and lower surface of cascade filter is carved with a large amount of vertically microchannels and is laminated on interior the support, compress by spring and fluid pressure, the groove between the lamination intersects, and forms the in-depth filtration unit of a series of unique filtration channels.Cascade filter when work, current be from outside flow to by lamination and to enter lamination inside, lamination compresses by spring and fluid pressure, pressure reduction is more big, lamination is pressed more tightly, has formed lamination self-locking performance high efficiency filter.
The lamination that its lamination of the laminated filter of promoting the use of at present arranges above has 2 kinds; A kind of is normal lamination, and its characteristics are that runner is line flowing channel, and runner quantity is few, and runner is long, and the loss of flood peak is bigger, and inflow-rate of water turbine is little, and filter efficiency is low.Another kind is follow-on single-stage lamination, and its characteristics are that runner is S type, annular, three kinds of runners stream line flowing channels such as auxiliary, and current form unique in-depth filtration through a plurality of filtered points, and filter effect is more quite a lot of than normal lamination.No matter all filter from the single-stage lamination but shortcoming is water body impurity particle size, be easy to make lamination to be covered with impurity on every side, conveyance capacity is affected.
Summary of the invention
The purpose of this utility model is to provide a kind of lamination filter multistage composite lamination, and it filters, and progression is many, and runner quantity is many, and runner is short, easy cleaning, and anti-obstruction, the loss of flood peak is little, and inflow-rate of water turbine is big, the filter efficiency height.
The purpose of this utility model is achieved in that a kind of lamination filter multistage composite lamination, on the positive and negative card of circle ring disk, arranging respectively and be the uniform oblique line shape runner of radioactive ray, the oblique line shape flow channel cross-section is shaped as the V-shaped flow road, the angle that oblique line shape runner and circle ring disk diameter intersect is 14 °-16 °, the uniform setting is concentrically ringed annulus runner respectively on the positive and negative card of circle ring disk, and the annulus runner disconnects the oblique line shape flow.
During the utility model work, when current enter the lamination filter, current are to flow to lamination inside in the annular frame that supports lamination, the current that enter in the lamination both can be from radial sealing oblique line shape flow passage on the circle ring disk front, can also flow by the annular channel on the annulus simultaneously, the current after filtering at last flow to outside the lamination.Lamination compresses by spring and fluid pressure, and pressure reduction is more big, and lamination is pressed more tightly, has formed lamination self-locking performance high efficiency filter.In addition, by the oblique line shape runner, two kinds of runners such as annular channel flow to the lamination outer rim to water by the lamination inner edge, and current form unique in-depth filtration through a plurality of filtered points, and impurity is attached to the outer surface of lamination, has formed good filter effect.The utility model is compared with normal lamination, and under the condition that width of flow path equates, the utility model has 9000 runners, and normal lamination only has 500 runners, and the follow-on lamination of single-stage is 3000 runners.Runner of the present utility model is short, little little than normal lamination and single-stage modified lamination of the loss of flood peak.Because the runner of the multistage lamination of the utility model is many, progression is many, and inflow-rate of water turbine has increased more than 50%.Therefore, the multistage lamination progression of the utility model is many, and runner quantity is many, and it is strong to adapt to the water quality ability, and runner is short, easy cleaning, and anti-obstruction, the kind of runner is many, and the loss of flood peak is little, and inflow-rate of water turbine is big, the filter efficiency height.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing, and Fig. 1 is main TV structure schematic diagram of the present utility model, and Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1, and Fig. 3 is that the B of Fig. 1 is to local structure for amplifying schematic diagram.
The specific embodiment
A kind of lamination filter multistage composite lamination, as Fig. 1, Fig. 2, shown in Figure 3, on the positive and negative card of circle ring disk 1, arranging respectively and be the uniform oblique line shape runner 2 of radioactive ray, oblique line shape runner 2 shape of cross sections are the V-shaped flow road, oblique line shape runner 2 is 14 °-16 ° with the angle that circle ring disk 1 diameter intersects, the uniform setting is concentrically ringed annulus runner 3 respectively on the positive and negative card of circle ring disk 1, and annulus runner 3 disconnects oblique line shape flow 2.The quantity of annulus runner 3 is 2, with oblique line shape runner 2 by in the circle ring disk 1 to outside be divided into three grades of runners, wherein first order oblique line shape runner suitable for reading wide be 0.44-0.46mm, the width suitable for reading of second level oblique line shape runner is 0.56-0.58mm, the width suitable for reading of third level oblique line shape runner is 0.68-0.70mm, and the degree of depth of three grades of runners is 0.73-0.75mm.The width of annulus runner 3 is 2mm, and the degree of depth is 0.73-0.75mm.The incline direction that is positioned at the oblique line shape runner 2 on the circle ring disk 1 positive and negative card is opposite.The external diameter of circle ring disk 1 is 154mm, and internal diameter is 90mm.The angle of oblique line shape runner 2 V-arrangement flow path walls is 55 °.
