Coupler synchronous type double-horizontal shaft vibration stirring machine

Abstract

The invention discloses a coupler synchronous type double-horizontal shaft vibration stirring machine, which comprises a machine frame and a vibration stirring device installed on the machine frame. Stirring drive and transmission devices are arranged at the left end of the vibration stirring device. Vibration drive and transmission devices are arranged at the right end of the vibration stirring device. The stirring drive and transmission devices and the vibration drive and transmission devices are installed on the machine frame. The vibration stirring device comprises a stirring cylinder and two stirring mechanisms. Both the two stirring mechanisms comprise hollow stirring shafts and a plurality of stirring units. The two stirring drive and transmission devices are respectively installed at the left ends of the two hollow stirring shafts. Synchronous couplers are installed between the two stirring drive and transmission devices. The two vibration drive and transmission devices are respectively installed at the right ends of the two hollow stirring shafts and respectively and fixedly connected with two vibration shafts. The coupler synchronous type double-horizontal shaft vibration stirring machine disclosed by the invention is simple and rational in structure and convenient for use; and mixed materials can be uniform in macroscopic and microscopic manners during a short time, thus, the stirring quality and the stirring efficiency are increased.

Description

technical field [0001] The invention relates to a mixer, in particular to a coupling synchronous twin-shaft vibration mixer mainly used for mixing concrete. Background technique [0002] The mixer is the direct equipment for concrete mixing. Its function is to mix the prepared materials into a uniform and quality mixture. According to the working principle, it can be divided into two categories: self-falling mixer and forced mixer. The self-falling mixer uses the stirring device to divide and lift the material in the mixing drum until the friction between the material and the stirring device is less than the component of gravity that makes the material slide down, the material falls by its own weight, so that each part of the material The mutual position is continuously redistributed to obtain uniform mixing. The power consumption of this kind of mixer and the wear of wearing parts are small, but the mixing intensity is not strong enough, and it is generally only suitable f...

AI Technical Summary

Problems solved by technology

As a conventional forced mixer, it also has the problem that the mixture is difficult to achieve microscopic uniformity, and when the stirring device is working, the speed near the center of the circular mixing drum is low, and the speed at the wall of the drum is high, making the mixing drum There are differences in the uniformity of different circular rings in the center, which leads to the center of the mixing drum becoming a low-efficiency mixing area, which delays the working time of the whole machine and leaves hidden dangers in quality; on the other hand, the fluidity of the mixture in the low-efficiency area is poor , easy to adhere to the stirring shaft, resulting in shaft holding phenomenon

The low-efficiency area of ​​mixing is an inherent defect determined by the structure of conventional forced mixers, which seriously affects the operation quality and efficiency of mixing equipment
