Description
Technical field
This utility model is related to agricultural water-saving irrigation equipment, belongs to the improvement of laminated filter lamination, the special lamination of the netted filter in flow channel of particularly a kind of multi-level cone shape.
Background technology
Water-saving irrigation drip irrigation has high demands to water quality, irrigation water will be filtered in advance, prevents dropper band from blocking.And laminated filter is exactly applied to the filter plant at drip irrigation water source, laminated filter is particularly suited for filtering the surface water containing algae, and good filtration effect.
The runner that its lamination of the laminated filter promoted the use of at present is arranged above is two kinds：One kind 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 kind is the netted runner of cylindricality, although runner quantity is many, is easily blocked by large particulate matter, filter efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of netted filter in flow channel of multi-level cone shape special lamination, and it is rational in infrastructure, dependable performance, current flow resistance in lamination can be reduced, do not obstructed by sand grain, the loss of flood peak is little, inflow-rate of water turbine is big, and filter efficiency is high, and backwash is convenient.
The purpose of this utility model is realized in：A kind of special lamination of the netted filter in flow channel of multi-level cone shape, including symmetrical and recessed annulus runner is respectively provided with the positive and negative card of circle ring disk, the positive and negative of circle ring disk are divided into inner disc and outer disk by annulus runner respectively, radial ray is uniformly arranged respectively on the positive and negative of circle ring disk, wherein it is located at the truncated cone first boss that uniform arrangement is arranged on the ray of inner disc card, the base diameter of first boss is 0.4, top surface a diameter of 0.3, highly for 0.4-0.6；The truncated cone second boss of uniform arrangement is arranged on the ray of outer disk card, the base diameter of second boss is 0.6, top surface a diameter of 0.5.
Operation principle of the present utility model：
During utility model works, when current enter laminated filter, current are to flow to inside lamination in the annular frame supporting lamination, enter current in lamination can from circle ring disk positive and negative radial uniform cone-shaped bulge composition the netted flow passage of two-stage, the current after filtration flow in lamination.Lamination passes through spring and Fluid pressure compression, pressure reduction is bigger, lamination pressure must be tighter, defines lamination self-locking performance high efficiency filter, in addition, water passes through conical netted runner by lamination outer rim, water (flow) direction is not subject to the obstruction of sand grain to weaken conveyance capacity, and current can flow through from arbitrary cone-shaped bulge, and in addition coarse granule impurity keeps off on coniform top, fine grained impurity keeps off in coniform bottom, defines good filter effect.
This utility model is rational in infrastructure, dependable performance, decrease current in lamination flow resistance it is achieved that not obstructed by sand grain, the loss of flood peak is little, inflow-rate of water turbine is big, improves filter efficiency, and backwash is convenient.
Brief description
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is main structure diagram of the present utility model, and Fig. 2 is the A-A cross section structure diagram of Fig. 1.
Specific embodiment
A kind of special lamination of the netted filter in flow channel of multi-level cone shape, as shown in Figure 1 and Figure 2, including symmetrical and recessed annulus runner 3 is respectively provided with the positive and negative card of circle ring disk, the positive and negative of circle ring disk are divided into inner disc 1 and outer disk 4 by annulus runner 3 respectively, radial ray is uniformly arranged respectively on the positive and negative of circle ring disk, wherein it is located at the truncated cone first boss 2 that uniform arrangement is arranged on the ray of inner disc 1 card, the base diameter of first boss 2 is 0.4, top surface a diameter of 0.3, highly for 0.4-0.6；The truncated cone second boss 5 of uniform arrangement is arranged on the ray of outer disk 4 card, the base diameter of second boss 5 is 0.6, top surface a diameter of 0.5.The external diameter of inner disc 1 is 110, and internal diameter is 90, and the external diameter of outer disk 4 is 150, and internal diameter is 130.On the same ray of inner disc 1 card, the centre-to-centre spacing between two adjacent first boss 2 is 0.5, and on the same ray of outer disk 4 card, the centre-to-centre spacing between two adjacent second boss 5 is 0.5.On inner disc 1 card inner radius adjacent ray, the spacing between the first boss 2 adjacent with same ray of the spacing between receipts first boss 2 is equal.
