Problems solved by technology

The friction of the mold hole on the material is the biggest factor that causes resistance, and also seriously reduces the life of the mold. This situation seriously affects the production cost and reliability of the biomass granulation equipment, and needs to be improved urgently.

Embodiment Construction

[0018] In order to more fully explain the implementation of the present invention, implementation examples of the present invention are provided. These implementation examples are only illustrations of the present invention, and do not limit the scope of the present invention.

[0019] Further detailed explanation of the present invention in conjunction with the accompanying drawings, each marked in the accompanying drawings is: 1: the upper end surface of the mold; 2: the lower end surface of the mold; 3: the origin of the pseudo-flow curve; 4: the pseudo-flow curve; 5: arc line; 6: straight line; 7: equal diameter hole; figure 1 The figure shows the shape of a cavity on the mold. There are hundreds or even thousands of cavities on a flat mold. After the biomass raw material enters the cavity, it is formed under the compression of the molding equipment. The biomass particles are finally The molding shape is the shape of the equal-diameter hole 7. The flow of material in the...

Abstract

A biomass flat die particle machine granulating die molded cavity includes an equal-diameter hole located in the lower part; the vertical section shape of the molded cavity successively comprises a quasi flow curve, a circular arc line and a straight line which are connected with each other from the upper end face of a die and the lower end face of the die along the equal-diameter hole axis, wherein the straight line is an edge line in the vertical direction of the equal-diameter hole; the quasi flow curve, the circular arc line and the straight line which are connected with each other rotate a circle around the equal-diameter hole axis to form an inner surface of the molded cavity. The die molded cavity has good effect on trial, the influence of the shape of the molded cavity on the die life is considered alone, and the die life can reach 3 to 4 times of the original die life.

Description

technical field [0001] The invention relates to a biomass mold, in particular to a cavity of a biomass flat mold granulator pelletizing mold, and belongs to the technical field of biomass molding equipment. Background technique [0002] The granulation process of biomass is to push the raw material into the hole of the mold through the pressure roller (or other extrusion device). The process of gluing and forming other materials such as cellulose inside the raw material is a process of material flow under high pressure and high temperature conditions. The main friction in the granulation process is the internal friction of the raw material and the friction resistance of the mold hole. , the internal friction of the raw material is a beneficial effect of promoting the heating of the material to promote the softening and gluing of the lignin; while the friction inside the mold hole will block the production and directly wear the mold; the structure of the mold hole generally h...
