Combined double-horizontal-shaft continuous stirrer

Abstract

The invention discloses a combined double-horizontal-shaft continuous stirrer which comprises a stirring main-body structure and a conveyer belt structure, wherein the stirring main-body structure comprises a stirring barrel, the stirring barrel is supported by a stirring barrel bracket arranged on the stirring barrel, the top of the stirring barrel is provided with a feed inlet, the bottom of the stirring barrel is provided with a discharge outlet, two stirring shafts are arranged in the stirring barrel side by side, stirring units on the two stirring shafts are alternately arranged, one side of the stirring barrel is provided with a power and a transfer structure, the conveyer belt structure is arranged at the lower part of the stirring barrel, the conveyor belt structure comprises a conveyor belt, a driving roller and a guide roller, the driving roller provides power for the conveyor belt, can rotate clockwise or counterclockwise, and can be subjected to frequency adjustment, the guide roller achieves a guide effect, and the conveyor belt is also used as the bottom surface of the stirring barrel. According to the stirrer, the bottom of the stirring barrel consists of a movable conveyor belt so as to adjust the flow characteristic of a stabilized soil material in the stirring barrel, so that the stirred time of the stabilized soil material in the stirring barrel is effectively increased, and further the stirring uniformity of stabilized soil can be improved.

Description

technical field [0001] The invention belongs to the field of stabilized soil material mixers, and relates to a continuous mixer, in particular to a combined twin-shaft continuous mixer for producing stabilized soil materials. Background technique [0002] Twin-shaft continuous mixer, as the core working device widely used in stabilized soil plant mixing equipment, determines the mixing quality and efficiency of finished stabilized soil and other pavement base materials. This kind of mixer mainly uses the motor to drive the mixing unit (stirring shaft, stirring arm, stirring blade) to rotate in the mixing drum to realize continuous forced stirring of the pavement base material. Since the stabilized soil material has the characteristics of continuous feeding, continuous mixing and continuous discharge during work, the length of the mixing drum of the continuous twin-shaft mixer is limited, and the residence time (time to be stirred) of the stabilized soil material in the mixin...

AI Technical Summary

Problems solved by technology

The simplest method is to directly increase the overall length of the mixing drum, but at the same time, the rigidity of the stirring shaft will deteriorate sharply, which will easily cause a series of problems such as deformation of the stirring shaft, excessive bearing load, and reduced reliability of the machine; some use two Two-stage stirring of an independent mixer, but this method complicates the mixing equipment, increases the space occupied by the mixing equipment and equipment cost; some reduce the stirring speed to increase the residence time of the stabilized soil material in the mixing drum, but This method will simultaneously cause a decrease in the circumferential speed of the mixing, thereby reducing the effect of the forced mixing of the stabilized soil material along the vertical and transverse directions of the mixing drum, and will still lead to poor uniformity of the produced stabilized soil material

[0004] At the same time, the existing twin-shaft continuous mixer generally adopts a structure without a liner. During the production process, the stabilized soil material will adhere to the inner wall of the mixing drum. Although it can form a certain protection for the drum wall during mixing, the The cleaning of this layer of adhesive material after production is time-consuming and laborious
