Granulating chamber of biological particle fuel extruding machine

Abstract

The invention relates to the technical field of extruding and granulating and especially relates to a granulating chamber of a biological particle fuel extruding machine. The granulating camber comprises a granulating chamber body, a rotating shaft, a stirring and extruding blade, a cylinder mould and a power device, wherein the cylinder mould is arranged in the granulating chamber body, a feedingpipe and a discharging opening are arranged on the granulating chamber body, the rotating shaft is arranged in the cylinder mould, the stirring and extruding blade is arranged in the peripheral direction of the rotating shaft, a cavity is formed in a mould wall of the cylinder mould, an air outlet is formed in an outer wall of the cylinder mould, a plurality of granulating pipes are arranged on the mould wall of the cylinder mould, an air blowing device is arranged in the granulating chamber body, a swinging plate is hinged to an inner wall of the cylinder mould, the stirring and extruding blade can extrude the swinging plate intermittently, an elastic cover is arranged between the inner wall, close to the swinging plate, of the cylinder mould and the swinging plate, a push portion is connected to the swinging plate, and the upper end of the push portion is arranged in the elastic cover. By means of the scheme, heat generated by the walls of the cylinder mould is reduced, further an effect on quality of a raw material in the cylinder mould is reduced, and meanwhile service life of the cylinder mould is prolonged.

Description

technical field [0001] The invention relates to the technical field of extrusion granulation, in particular to a granulation chamber of a biological particle fuel extruder. Background technique [0002] Extrusion granulation is to prepare the soft material from the raw powder with an appropriate binder, put it into a porous ring die (usually an orifice or a screen with sieve holes), and use forced extrusion to make it from the porous ring die. The other side is discharged, and then undergoes appropriate granulation or shaping granulation method. At present, the extruder is mainly composed of a main motor, a reducer, a granulation chamber, a dust cover, and a dial motor. The granulation chamber is the core part of the extruder. For compact particles. [0003] The traditional extruder granulation is divided into front extrusion type and side extrusion type; the granulation chamber of the front extrusion type includes a helical blade driven by a motor, a rotating shaft, a cyl...

AI Technical Summary

Problems solved by technology

[0004] The following technical problems exist in the prior art: because a large amount of frictional heat will be generated between the raw material and the die wall of the cylindrical die, and a large amount of frictional heat will also be generated when the raw material is pressed into the pelletizing hole, the heat generated on the cylindrical die wall cannot be timely Export, heat not only affects the quality of raw materials inside the cylinder mold, but also shortens the service life of the cylinder mold for a long time
