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...
