Accurate fertilizer feeding device for compound fertilizer production

Abstract

The invention discloses an accurate fertilizer feeding device for compound fertilizer production. The device comprises a mixing box, a mounting seat is rotatably mounted on the mixing box through a mounting structure, a feeding hole is formed in the center of the mounting seat, a plurality of moving holes communicated with the feeding hole are formed in the mounting seat, the moving holes are arranged in a step shape, and a cover cylinder is mounted between the mixing box and the mounting seat through a pushing mechanism. The accurate fertilizer feeding device has the advantages that the multiple feeding pipes are arranged, so that different types of materials can pass through special pipelines when entering the mixing box, and the influence on compound fertilizer production is reduced; meanwhile, through the arrangement of a shaking structure, the change of residual materials in the feeding pipes can be effectively reduced, and the production precision is improved; and meanwhile, through cooperative use of a filter screen and a grinding structure, large-particle materials screened each time can be effectively ground, rapid mixing of different materials in the compound fertilizer is facilitated, and the production speed of the compound fertilizer is increased.

Description

technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a fertilizer precision feeding device for compound fertilizer production. Background technique [0002] Compound fertilizers are widely used due to their advantages of high nutrient content, less auxiliary components and good physical properties. At present, during the production of compound fertilizers, different types of materials are added through the feeding pipe in a certain order (production process), but This kind of adding method has the following disadvantages: when the material is added, part of it adheres to the inner wall of the tube, which will affect the overall manufacturing accuracy. Under certain conditions, this process will also have a certain impact; as the patent No. CN101921143A discloses a compound fertilizer and a compound fertilizer production process thereof, at a certain temperature, urea or ammonium nitrate is first fused, and then adding ...
