Abstract

The invention discloses a centrifugal gravel filtering device of water-fertilizer integrated equipment. The centrifugal gravel filtering device comprises a cylinder, a top cover is installed at the top of the cylinder, a water inlet is formed in the top cover, the axis of the water inlet is tangent to the inner wall of the top cover, and a sewage storage groove is formed in the inner wall of the cylinder; a filter is fixed to the interior of the cylinder through a pressing plate and located below the sewage storage groove, and comprises a metal filter net at the surface layer, the metal filternet is filled with a quartz filtering sand layer, a water outlet is formed in the side wall of the cylinder, the direction of the water outlet is opposite to that of the water inlet, and the axis ofthe water outlet is tangent to the inner wall of the cylinder. By means of the centrifugal gravel filtering device, the defect in the prior art can be overcome, impurity-free water can be provided forthe water-fertilizer integrated equipment, and it is guaranteed that during use of the water-fertilizer integrated equipment, blockage and other problems do not occur.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation equipment, in particular to a centrifugal sand filter device for integrated water and fertilizer equipment. Background technique [0002] Agriculture belongs to the primary industry and is the basic industry that provides support for the construction and development of the national economy. Agricultural high-efficiency water-saving and fertilizer-saving technology is one of the important fields of research and development of modern agriculture. More and more people pay attention to the development of modern agricultural economy. In the field of high-efficiency water-saving and fertilizer-saving agriculture, it is necessary to research and design suitable new water and fertilizer integrated equipment. At present, there is little development of filtration technology for water and fertilizer integrated equipment in China; most of the research on water and fertilizer integrated equipme...
