Raw material screening device for fertilizer production

Abstract

The invention discloses a raw material screening device for fertilizer production and relates to the technical field of fertilizer production. The raw material screening device comprises a box body. Afeeding hopper is fixedly connected to the top of the box body. A scattering box is fixedly connected to the inner top wall of the box body. The upper end of the scattering box is fixedly communicated with the feeding hopper. A scattering mechanism is arranged in the scattering box. A material conveying cylinder is arranged in the box body. The two ends of the material conveying cylinder are fixedly connected to the two inner side walls of the box body. When in use, through a double-shaft motor, the output end of the double-shaft motor drives a rotating shaft I to rotate through a belt and atransmission wheel I and a transmission wheel II, so that a spiral blade is driven to rotate, the spiral blade can drive the raw materials to rotate in the material conveying cylinder, the heating time of the raw materials in the conveying process is prolonged, the raw materials are in more sufficient contact with the heat, and the heating effect of electric heating wires on the raw materials is improved, so that the effect of drying the raw materials before screening is better.

Description

technical field [0001] The invention relates to a relatively large range, in particular to a raw material screening device for fertilizer production. Background technique [0002] With the development of science and technology, fertilizers used in agricultural production have also been transferred from natural products to modern inorganic fertilizers. Fertilizers refer to a class of substances that provide one or more essential nutrients for plants, improve soil properties, and increase soil fertility levels. , is one of the material bases of agricultural production, mainly including ammonium phosphate fertilizers, macroelement water-soluble fertilizers, medium element fertilizers, biological fertilizers and organic fertilizers. [0003] In the production process of fertilizers, the screening of raw materials is one of the important links. Fertilizer raw materials contain many substances, so the types and sizes of fertilizer raw materials are also different. Processing raw m...

[0003] In the production process of fertilizers, the screening of raw materials is one of the important links. Fertilizer raw materials contain many substances, so the types and sizes of fertilizer raw materials are also different. Processing raw materials with suitable diameters can improve the quality of fertilizers. Existing Although the advanced raw material screening device can screen the raw materials, due to the lack of equipment for drying the raw materials, the wet raw materials are directly screened, and the screening effect is not good because the raw materials stick together. Therefore, we propose a fertilizer Raw material screening device for production
