example

[0013] One example, the filter screen 1 is a rectangular mesh, the water inlet tank 2 and the water outlet tank 6 are rectangular grooves, the shape of the boss 3 is rhombus, the inner angle is 30 degrees, and the number of bosses 3 is 8. For the flow channel The tooth-like structure 5 on part of the outer edge is an isosceles triangle, the angle between the teeth is 30 degrees, and interlaced with the bosses 3 .

[0014] The water flows in from the mesh filter 1 with a certain working head, and enters the water inlet tank 2 after being filtered. Becomes slower and less likely to form turbulent eddies. Then the water flow enters the flow channel part 4. When the water flow passes through a diamond-shaped boss, the water flow is divided into two and merged into one water flow at the tooth-shaped structure, and then passes through the next diamond-shaped boss and the tooth-shaped structure, so that the water flow appears as The labyrinthine water flow that flows round and round...

Abstract

The sheet ambient-flow irrigator includes water inlet channel, water outlet channel and flow channel, the water inlet channel is communicated to the water inlet of the flow channel, and the water outlet channel is communicated with the water outlet of the flow channel. The sheet ambient-flow irrigator features the water inlet channel with filtering net; and the flow channel with linear homogeneously distributed bosses in the middle part and linear homogeneously distributed toothed structures on two sides to form labyrinth flow channel. The flow channel of the present invention has ambient water flow and outstanding energy dissipating effect, and the irrigator may be used widely in irrigation of cotton, sugar cane, vegetable, etc.

Description

technical field [0001] The invention relates to a water-saving drip irrigation device, in particular to a slice-type bypass flow anti-clogging sprinkler. Background technique [0002] Water-saving irrigation is the main measure taken by countries all over the world to develop modern agriculture. As an advanced high-standard irrigation technology in water-saving irrigation, micro-irrigation has been adopted by more than 100 countries in the world. Among them, drip irrigation has the most obvious advantages such as water saving, production increase, and high efficiency, and can be widely used in the cultivation of economic crops such as fruit trees, vegetables, flowers, and medicinal materials. [0003] The dripper is one of the most critical components of the drip irrigation system. The structure of the dripper and its hydraulic performance have a great influence on the uniformity, anti-clogging ability and system life of the drip irrigation system. The hydraulic performance...
