Abstract

The utility model relates to water-saving irrigation equipment, in particular to a special lamination of a lamination filter belonging to improvement of lamination structure of the lamination filter. Convex edges presenting radial closed broken lines are evenly arranged on the front surface of a ring-shaped disc; line-shaped flow channels are evenly arranged on the convex edge plane; ring-shaped flow channels presenting concentric circles are evenly arranged on the back surface of the ring-shaped disc; line-shaped auxiliary flow channels presenting radial shape are evenly arranged on the back surface of the ring-shaped disc to cut off the ring-shaped flow channels. The special lamination of the lamination filter has advantages of more flow channel number, short flow channel, easy clean, good anti-clogging performance, more types of flow channels, small head loss, large flow rate and high filter efficiency.

Description

A kind of lamination filter-specific lamination

Technical field

The utility model relates to water-saving irrigation device, belongs to the improvement of laminated filter lamination, particularly a kind of lamination 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 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 a 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 big more, lamination is pressed tightly more, 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 is provided with above is a 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.

The utility model content

The purpose of this utility model is to provide a kind of lamination filter-specific lamination, and its runner quantity is many, and runner is short, easy cleaning, and anti-the 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.

The purpose of this utility model is achieved in that a kind of lamination filter-specific lamination, the uniform fin that is radial polygon shape that is being provided with on the front of circle ring disk, the horizontal uniform linear runner that is being provided with on the fin face, the uniform setting is concentrically ringed annular channel on the back side of circle ring disk, uniformly on the back side of circle ring disk radial linear auxiliary flow is being set annular channel is disconnected.

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 the linear flow passage of the fin face horizontally set of radial polygon shape on the circle ring disk front, can also flow by the annular channel on the circle ring disk back side, can also radial linear auxiliary flow is set flow by uniform on the circle ring disk back side, the current after filtering at last flow to outside the lamination.Lamination compresses by spring and fluid pressure, and pressure reduction is big more, and lamination is pressed tightly more, has formed lamination self-locking performance high efficiency filter.In addition, by the runner on the fin face, three kinds of runners such as annular channel and auxiliary flow 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 3000 runners, and normal lamination only has 500 runners, and runner of the present utility model is short, and the loss of flood peak is little littler than the normal lamination.Because runner of the present utility model is many, inflow-rate of water turbine increases more than 50%.Therefore, the utility model runner quantity is many, and runner is short, easy cleaning, and anti-the 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.
