Preparation method of buried micropore ceramic root-irrigation emitter

Abstract

The invention discloses a preparation method of a buried micropore ceramic root-irrigation emitter. According to the method, clay and furnace slag are selected. Through the technology of raw material selection, preparation, mould manufacturing, casting, sintering and the like, the prepared buried micropore ceramic root-irrigation emitter has a simple structure and can operate under the condition of low-pressure water supply. When a working head is 0.5m-1m, flow of the irrigation emitter is 4.2-8.5L / h. 1-2 buried micropore ceramic root-irrigation emitters can be configured for each tree. The preparation method is simple. It is convenient to draw materials. Cost is low. The service life of the irrigation emitter buried underground is more than 15 years. The cost of each irrigation emitter is about 0.5 yuan. One-time investment in the irrigation emitter is saved by more than 30% compared with that in a general irrigation emitter. Energy consumption is reduced by more than 20%. Clogging problem can be prevented effectively. The preparation method is of important practical significance in the development of water-saving irrigation technique.

Description

technical field [0001] The invention belongs to the technical field of agricultural economic forest irrigation in arid areas, and in particular relates to a preparation method of a microporous ceramic root irrigation sprinkler. Background technique [0002] As the most water-saving irrigation technology, micro-irrigation is adopted for the irrigation of more and more types of field and commercial crops. According to the water requirements and irrigation systems of different crops, the development of corresponding emitters is the demand for the development of micro-irrigation. [0003] At present, microporous ceramics are mainly used in the filtration of various liquids and gases, such as the filtration of industrial water and domestic water. It is a porous ceramic material with a pore size of micron (or submicron) and has stable properties and corrosion resistance Strong, uniform and narrow pore size distribution, low cost, long service life and other advantages. Microporou...
