Oppositely-rolling granulator for organic fertilizer

Abstract

The invention relates to the technical field of machinery, and provides an opposite-rolling granulator for organic fertilizers, which comprises a feeding mechanism, a granulating mechanism and a granulating mechanism, a forming mechanism; the forming mechanism comprises a forming chamber and pressing rollers which are arranged in the forming chamber and are oppositely arranged; a material forming hole is formed in the edge of the outer contour of the pressing roller, a feeding cavity used for transferring formed materials out of the forming mechanism is formed in the pressing roller, and the material forming hole communicates with the feeding cavity. And a drying mechanism. Through the pressing rollers which are driven to rotate oppositely, materials can be effectively and respectively transferred into the feeding cavities of the two pressing rollers, so that the two heated pressing rollers are used for respectively carrying out extrusion forming work and drying work on the materials. Compared with the prior art with only one working channel for the materials to pass through, the double-roller granulator provided by the invention performs double-channel drying on the materials, so that the organic fertilizer is subjected to double moisture evaporation compared with the prior art, the drying capacity of the granulator is effectively improved, and the integrity of the materials is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of feed processing machinery, in particular to a counter-roll granulator for organic fertilizers. Background technique [0002] Organic fertilizer refers to the by-product resources rich in organic matter such as animal excrement or animal and plant residues as the main raw material. Organic fertilizers tend to have a high water content, especially those obtained by processing plant residues. Organic fertilizers need to be granulated to make animal and plant residues into specific shapes, so that the materials have better use characteristics. [0003] In the prior art, for example, the multi-process feed processing equipment disclosed by the publication number CN111436633A includes a fuselage mechanism, a mixing and granulating mechanism, and a granulating box mechanism. The material forming work is realized by setting granulation holes on the granulation box body and extruding the material in the granulat...

AI Technical Summary

Problems solved by technology

However, the drying efficiency of the above-mentioned granulator still cannot meet the drying requirements of organic fertilizers, resulting in problems such as deformation, crushing, and adhesion of organic fertilizer particles after granulation

[0004] The integrity of organic fertilizer granules will directly affect the price of material granules. For this reason, those skilled in the art urgently need a granulator with good drying effect to solve the problem of poor drying effect of organic fertilizers caused by existing granulators. The organic fertilizer granulator has poor material forming effect, and it is difficult to meet foreign requirements for high integrity of materials.
