Continuous mixing-kneading extruding machine

Abstract

The invention belongs to the technical field of mixing and kneading of wall body materials, and relates to a continuous mixing-kneading extruding machine, which comprises a forced feeding device, a main transmission mechanism and a cylinder body stand, wherein the section of an inner cavity of a cylinder body (41) is shaped as 8 or circle; forced feeding spirals are arranged on a main shaft of a mixing and kneading rotor, and screw pitches of a plurality of groups of forced feeding spirals are gradually reduced from the feeding end to the discharging end; fixed sleeves (25) are arranged amongthe plurality of groups of forced feeding spirals, and mixing and kneading tools are arranged on the fixed sleeves (27); an extruding mechanism is formed by a discharging head (7) and one group of forced feeding spirals of the mixing and kneading rotor; and the discharging part of the discharging head (7) is shaped as a transverse 8 or circle, and is provided with discharging holes enabling materials to pass through, wherein the discharging holes are arranged at intervals. The invention has the advantages of lower power consumption index during the large-yield operation, high kneading precision, and realization of high difficulty and high accuracy micro kneading.

Description

technical field [0001] The invention belongs to the technical field of wall material mixing and kneading, and mainly relates to a continuous kneading extruder, which is mainly used for extruding between solid powder and granular materials containing a certain amount of water and between solid powder and granular materials and a certain amount of binder. Mix, knead. Background technique [0002] Generally, the commonly used kneading, kneading and extrusion equipment have two forms of continuous and batch in terms of operation methods. In terms of their basic principles, there are strong shear kneading, strong convection kneading, etc., and there are many more in terms of structural forms. diverse. Traditional kneading, kneading, and extrusion equipment include wheel mills, single-screw extruders, twin-screw extruders, continuous mixers, etc. Some of these equipments have high mixing accuracy but high power consumption and low output. To achieve large-scale production operat...
