Abstract

The invention discloses a spiral flow self-desilting type desilting filter tank, and relates to the technical field of agricultural irrigation. The desilting filter tank comprises a desilting basin, aclean water basin is arranged at the tail end of the desilting basin, a water inlet gate is arranged at the front end of the desilting basin, a water outlet gate is arranged at the rear end of the clean water basin, a first notch is formed in a wall body between the desilting basin and the clean water basin, and a plurality of overflow grooves are formed in the bottom surface of the first notch.A flow regulating plate in the desilting basin divides the internal space of the desilting basin into a flow stabilizing section and a desilting section. At least two desilting scrolls are arranged atthe bottom of the desilting section, one end of each desilting scroll penetrates through the side wall of the desilting basin and extends out of the desilting basin, and a second notch is formed in the desilting scroll located in the desilting basin. The desilting filter tank can achieve the dual effects of desilting and filtering within the shortest effective length, the desilting efficiency isgreatly improved, and the requirement that surface water enters ditches and canals for irrigation is met.

Description

technical field

[0001] The invention relates to the technical field of agricultural irrigation, in particular to a spiral flow self-discharging sand filter pond. Background technique

[0002] At present, the problems of water shortage and water pollution in our country are becoming more and more serious, and it is an inevitable trend to carry out extensive research on water-saving irrigation agriculture. Most of the water sources used in water-saving irrigation technology are surface water, but most of the surface water has a high sediment content. If the surface water is directly used in the irrigation system, it will inevitably cause blockage of pipelines and other facilities, which is not conducive to Agricultural irrigation. Therefore, water-saving irrigation technology requires water sources with very little sand content, so it is necessary to purify the sand in the surface water before irrigation.

[0003] In order to achieve this purpose, grit chambers are commonly ...
