Double-horizontal-shaft continuous stirrer with oppositely arranged inner and outer stirring units

Abstract

The invention discloses a double-horizontal-shaft continuous stirrer with oppositely arranged inner and outer stirring units. The double-horizontal-shaft continuous stirrer comprises a rack, a stirring cylinder, a motor, a coupler and a speed reduction box, wherein the stirring cylinder, the motor, the coupler and the speed reduction box are installed on the rack; the left end and the right end of the stirring cylinder are respectively provided with a material inlet and a material outlet; two parallelly arranged stirring shafts are respectively connected with the left and right side walls of the stirring cylinder movably, and the left ends of the two stirring shafts extend out of the outer side of the stirring cylinder, and are provided with a pair of externally meshed synchronous gears; each stirring shaft is provided with a plurality of outer stirring units and inner stirring units at intervals from left to right; an output end of the motor is connected with an input shaft of the speed reduction box by a coupler; the output shaft of the speed reduction box is connected with the left end of one of the stirring shafts. The double-horizontal-shaft continuous stirrer can prolong the stirring time of materials in a stirring machine under the conditions that the stirring length is not increased and the stirring speed is not reduced, and further the stirring uniformity is improved, and meanwhile, the material journal sticking phenomenon can be improved via the radial stirring motion between the inner and outer stirring units.

Description

Technical field: [0001] The invention belongs to the field of stabilized soil material mixers, and relates to a continuous stirring device, in particular to a twin-shaft continuous stirring device with opposed internal and external stirring units. Background technique: [0002] The twin-shaft mixer is a mixer type widely used in the field of construction engineering. There are two parallel stirring shafts in the mixer body. The stirring arms are fastened on the stirring shafts according to a certain arrangement, and the stirring blades are fastened according to a certain installation angle. on the stirrer arm. When the stirring shaft rotates, the material is forced to stir in the mixer through the rotating stirring blade. Twin-shaft mixers can be divided into two types: continuous type and batch type. Among them, when mixing stabilized soil materials, they are mostly continuous type mixers, which have the characteristics of continuous feeding, continuous mixing and continuo...

AI Technical Summary

Problems solved by technology

For example: increasing the length of the mixer will not only reduce the rigidity of the mixer shaft, but also cause large deformation during work, which will affect the service life of the mixer device and external support bearings, and will also increase the overall size of the mixer; reduce the speed of the mixer shaft, although It can reduce the axial movement speed of the material, but at the same time it will also reduce the circumferential stirring speed of the material, which not only causes the material throwing effect in the vertical direction to deteriorate, but also reduces the interaction between the two stirring shafts. The uniform mixing of soil materials is still very unfavorable; multi-stage mixing is to prolong the mixing time through two separate mixers, which also increases additional equipment, resulting in an increase in production costs and floor space
