Straw granulation method based on straw granulation equipment

Abstract

The invention discloses a straw granulation method based on a straw granulation device. The device comprises a rack base, a homogenization device mechanism, a particle molding mechanism, a particle cutting-off mechanism and a discharging mechanism, wherein the particle molding mechanism comprises an annular mold; the annular mold is internally provided with two pressing roller devices; the particle cutting-off mechanism is located at the outer part of part of the particle molding mechanism; the discharging mechanism is located at the left sides of the particle molding mechanism and the particle cutting-off mechanism; pin columns are arranged on an outer surfaces of the pressing roller devices; the contact area of pressing rollers, a material and the annular mold is reduced; the method is adopted so that the abrasion on the pressing rollers and the annular mold can be reduced.

Description

technical field [0001] The invention relates to the field of crop processing, in particular to a straw granulation method based on straw granulation equipment. Background technique [0002] Chinese agriculture has a long history. Traditionally, a small amount of straw is used for raising livestock, and most of them are disposed of by burning. This disposal method not only pollutes the environment, but also poses a fire hazard. Making straw into granules is a new processing method and process. Due to the structural design defect between the ring die and the pressure roller in the existing straw granulation equipment, the pressure roller rotates at a high degree in the ring die and rubs against the material. A large amount of heat is generated, and the temperature can reach 220 degrees. The high temperature makes the material of the pressing roller brittle, and there is a small amount of hard matter in the straw, so the wear of the pressing roller and the ring die is very seri...

Problems solved by technology

[0002] China's agriculture has a long history. The traditional way of treating straw is to use a small amount of it for raising livestock, and most of it is disposed of by burning. This treatment method not only pollutes the environment, but also poses a fire hazard.

Making straw into granules is a new processing method and process. Due to the structural design defect between the ring die and the pressure roller in the existing straw granulation equipment, the pressure roller rotates at a high degree in the ring die and rubs against the material. A large amount of heat is generated, and the temperature can reach 220 degrees. The high temperature makes the material of the pressing roller brittle, and there is a small amount of hard matter in the straw, so the wear of the pressing roller and the ring die is very serious during the granulation process, and these two materials need to be replaced frequently. Parts, which increase production costs and reduce work efficiency
