Problems solved by technology

[0002] In agricultural production, the precision of the filter mainly depends on the type and content of impurities in irrigation water. In different periods and regions, the type and content of impurities are quite different. Using too small filtration precision will cause the filter to quickly Clogging, and the use of excessive filtration precision will lead to poor filtering effect, and the dripper on the drip irrigation belt is obviously clogged

Abstract

The invention discloses a hydraulically controlled variable precision laminated filter and its operating process. The filter consists of a laminated filter system, a piston rod cylinder and a hydraulic control system, wherein the laminated filter system is the main body, There are two piston rod cylinders, which are respectively arranged on the top and bottom of the laminate filter system, and the hydraulic control system is connected with the piston rod cylinders. The hydraulically controlled variable precision laminated filter of the present invention adjusts the working area of ​​the laminated sheets by using a hydraulically controlled piston, and finally achieves the function of adjusting the filtering precision.

Description

technical field [0001] The invention belongs to the technical field of agricultural water conservancy equipment, and in particular relates to a hydraulically controlled variable precision laminated filter and its operating process. Background technique [0002] In agricultural production, the precision of the filter mainly depends on the type and content of impurities in irrigation water. In different periods and regions, the type and content of impurities are quite different. Using too small filtration precision will cause the filter to quickly Clogging, and the use of excessive filtration precision will lead to poor filtering effect, and the dripper on the drip irrigation belt is obviously clogged. Contents of the invention [0003] Aiming at the characteristic that the water quality of irrigation water varies greatly with solar terms in agricultural production, the present invention provides a hydraulically controlled variable precision laminated filter and its operatin...
