Abstract
The utility model relates to agricultural water-saving irrigation equipment, belongs to the improvement of a structure of a special laminated sheet for a netty flow channel filter, and particularly relates to a special laminated sheet for a netty flow channel filter. Radial rays are evenly distributed on the front face and back side of a ring disk, cylindrical lug bosses are evenly arranged on each ray, the heights of the cylindrical lug bosses are within the range of 0.4-0.6mm, and the distances among the first cylindrical lug bosses on the adjoining rays at the inner-diameter place of the ring disk are equal to those of the adjoining cylindrical lug bosses on the same ray. The special laminated sheet provided by the utility model is reasonable in structure, the water flow is small in flow resistance in the laminated sheet and can not be obstructed by sand grains, and the special laminated sheet is small in head loss, high in overflow quantity, high in filter efficiency, and convenient in back-washing.
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 netted runner filter-specific lamination.
Background technology
The water-saving irrigation drip irrigation will be filtered irrigation water in advance to the requirements in water quality height, prevents that the dropper band from stopping up.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 laminated 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 runner that its lamination of the laminated filter of promoting the use of at present arranges above 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.
Summary of the invention
The purpose of this utility model is to provide a kind of netted runner filter-specific lamination, and it is rational in infrastructure, can make current flow resistance in lamination little, is not subjected to obstructing of sand grain, and the loss of flood peak is little, and inflow-rate of water turbine is big, the filter efficiency height, and backwash is convenient.
The purpose of this utility model is achieved in that a kind of netted runner filter-specific lamination, uniform on the positive and negative card of circle ring disk radial ray is being set, the columnar projections of uniform arrangement is being set at ray, the height of columnar projections is 0.4-0.6mm, the spacing between the first columnar projections on the adjacent ray of circle ring disk card inner radius with equate in the spacing between the adjacent columnar projections on the same ray.
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, enter the netted flow passage that the current in the lamination can be formed from radial uniform columnar projections on the circle ring disk positive and negative, and the current after the filtration flow to outside the lamination.Lamination compresses by spring and fluid pressure, pressure reduction is more big, lamination is pressed more tightly, formed lamination self-locking performance high efficiency filter, in addition, water passes through netted runner by the lamination inner edge, water (flow) direction is not subjected 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, netted runner is stronger than linear pattern runner conveyance capacity, and the loss of flood peak is littler than the normal lamination.Because netted runner of the present utility model makes inflow-rate of water turbine increase more than 50%.Therefore, the netted runner easy cleaning of the utility model, anti-obstruction, the loss of flood peak is little, and inflow-rate of water turbine is big, the filter efficiency height.The utility model is rational in infrastructure, and current flow resistance in lamination is little, is not subjected to obstructing of sand grain, and the loss of flood peak is little, and inflow-rate of water turbine is big, good filtration effect, and backwash is convenient.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described, Fig. 1 is main TV structure schematic diagram of the present utility model, and Fig. 2 is that the A of Fig. 1 is to partial side TV structure schematic diagram.
The specific embodiment
A kind of netted runner filter-specific lamination, as Fig. 1, shown in Figure 2, at circle ring disk 1 just, uniform on the helical cast face radial ray is being set, the columnar projections 2 of uniform arrangement is being set at ray, the height of columnar projections 2 is 0.4-0.6mm, the spacing between the first columnar projections 2 on the adjacent ray of circle ring disk 1 card inner radius with equate in the spacing between the adjacent columnar projections 2 on the same ray, the shape of columnar projections 2 is made of cylinder or prism, the diameter of cylinder bodily form columnar projections 2 is 0.5mm, be 0.1mm in the spacing between the adjacent columnar projections 2 on the same ray of circle ring disk 1 card, the external diameter of circle ring disk 1 is 110mm, and internal diameter is 90mm.
