Description

Technical Field

[0001] This invention relates to the field of irrigation technology, and more particularly to a water-saving irrigation device for agricultural and forestry crops. Background Technology

[0002] Drip irrigation technology is one of the most efficient water-saving irrigation methods currently available. However, its application in the Yellow River irrigation areas of Northwest my country faces the severe challenge of extremely high sediment content in the water source. The sediment particles in the Yellow River are fine and the mineral composition is complex. Direct use in drip irrigation will quickly lead to severe clogging of the filtration system and the emitters (drippers), causing the system to malfunction and resulting in high maintenance costs.

[0003] In existing technologies, common filtration methods are mostly single-stage or simple two-stage filtration. These devices have obvious drawbacks when dealing with Yellow River water: First, it is difficult to balance filtration accuracy and dirt-holding capacity, and they are easily clogged quickly, requiring frequent shutdowns for disassembly and cleaning, which seriously affects the continuity of irrigation operations; second, they lack efficient pre-stage coarse filtration units, and fine sand and clay particles directly impact the downstream fine filtration units, significantly shortening their service life; third, existing devices generally do not have online automatic cleaning functions, relying on manual maintenance, which is inefficient and labor-intensive.

[0004] Therefore, it is necessary to provide a new water-saving irrigation device for agricultural and forestry crops to solve the above-mentioned technical problems. Summary of the Invention

[0044] The working principle of the water-saving irrigation device for agricultural and forestry crops provided by this invention is as follows:

[0045] During irrigation, the water source pump 9 is started. After the Yellow River water is initially intercepted by the coarse filter at its inlet end, large particles of impurities are pumped into the third water pipe 8. The high-pressure water flow enters the cylinder 202 of the vortex sand removal mechanism 2 through the tangentially set vortex inlet hole 205, forming a high-speed vortex. Under the action of centrifugal force, the mud and sand particles with a density greater than water are thrown towards the cylinder wall and concentrated spirally downward along the cone tube 203. Finally, they are periodically discharged through the first drain valve 204 at the bottom. The relatively clean water rises in the center of the vortex and enters the first water pipe 3 through the outlet hole 206 at the top.

[0046] The initially purified water enters the disc filter box 402 of the disc filter mechanism 4 through the first water pipe 3 and the first connection hole 403 at the bottom. The water flows from bottom to top through multiple filter plates 405 with specific angles. The V-shaped filter gaps can effectively trap finer suspended particles. The water that has completed fine filtration flows out from the second connection hole 406 at the top and enters the second water pipe 5. The trapped impurities are deposited at the bottom of the conical box and can be discharged through the second drain valve 404.

[0047] Water flows through the second water pipe 5 and enters the mesh filter box 601 of the mesh filter mechanism 6 through the first mounting hole 606. First, it passes through the first filter screen 603 with a larger aperture to intercept larger particles that may escape. Then, the water flows around the first filter partition 602 and downwards, and then passes through the second filter screen 605 with a smaller aperture for final fine filtration. The completely clean water is collected on the other side of the box and is drawn by the drip irrigation pump 11 through the fourth water pipe 10. Finally, the water is evenly irrigated to crops through the drip irrigation pipe and drip irrigation nozzle.

[0048] When the disc filter mechanism 4 needs cleaning, the backwash mechanism 7 is activated. The high-pressure flushing pump 703 draws clean water from the flushing water tank 701 and pumps it into the top of the disc filter box 402 through the sixth water pipe 704. The high-pressure water flow backwashes the filter plates 405, washing away the mud and sand embedded in the gaps. The flushing wastewater flows back to the flushing water tank 701 through the fifth water pipe 702 for sedimentation, or is directly discharged through the second drain valve 404. This process allows for online maintenance without shutting down the system.
