Abstract

This invention discloses a strengthened multifunctional blockage experimental apparatus for micro-irrigation, comprising a test platform, a mixing tank, a water pump, three filters, a drain tank and an air cylinder; inlet and outlet of each filter is disposed with a pressure gauge and a control valve, inlet of the air cylinder is disposed with a control valve; the test platform is respectively connected with the filter, air cylinder and pressed-water pipes via pipes of the control valve; the mixing tank is disposed with ring vessels internally, the mixing tank is connected with the water pump via water supply pipe of the dual-band control valve, the water pump is connected with the recycled water pipe via the water supply pipe. This invention is a multifunctional, auto-controllable, conveniently extendable and movable strengthened multifunctional blockage experimental apparatus for micro-irrigation apparatus, capable of testing hydraulic power, anti-blockage performance (comprising physical, chemical and biological blockage) of douche, and simultaneously testing filter characteristics on different blockage medium, in order to realize instant anti-blockage evaluation for micro-irrigation douche and filter.

Description

technical field [0001] The design of the invention belongs to the cross field of water conservancy and machinery, and in particular relates to an experimental device for intensified clogging test in a micro-irrigation laboratory. technical background [0002] Emitters and filters are key components in micro-irrigation systems, and clogging is the most important phenomenon that occurs during the working process of irrigators and filters. The causes of clogging in micro-irrigation systems can be attributed to physical clogging, chemical clogging and biological clogging. Physical clogging is mainly caused by sediment particles and organic impurities in water flow; chemical clogging is mainly caused by the production, growth and precipitation of insoluble compounds in water. Caused; Bio-clogging is mainly caused by immersion of crop roots in water flow or microbial ooze. The blockage of the emitter will cause the pressure and flow relationship of the emitter and other emitters ...

AI Technical Summary

Problems solved by technology

[0004] To sum up, most of these experimental devices are limited to the experimental research on the hydraulic performance of emitters. Although the blockage experimental device takes into account the uniformity of irrigation, due to the experiments under laboratory conditions and the need for too many manual operations, the final obtained There is still a certain deviation between the emitter index and the actual application, and most devices can only test the pressure and flow relationship of the emitter. Although the anti-clogging and hydraulic performance experimental device of the micro-irrigation emitter of China Agricultural University can not only test the pressure of the emitter .In addition to the flow relationship, the anti-clogging performance of the emitter can also be tested, but these devices have no specific test methods for the anti-clogging ability of the emitter and filter
