A vibrating multi-shaft rotary mixer

Abstract

The invention discloses a vibrating multi-axis spiral mixer, which is mainly composed of a mixing drum, an elastic support, a supporting base, a stirring shaft, a supporting seat of the stirring shaft, an exciting device and a multi-axis rotating driving device. The stirring shaft is driven to rotate by the multi-axis rotating drive device, so as to realize the stirring and conveying functions of different helical blades. When stirring, the vibration-exciting device drives the mixing drum to vibrate, and at the same time, the elastic support realizes support, buffering and energy storage. The mixer has simple and reasonable structure, low manufacturing cost and can effectively improve the mixing quality.

Description

technical field [0001] The invention relates to a vibrating multi-axis spiral mixer, which is suitable for mixing and crushing materials in chemical industry, metallurgy, food, medical treatment and the like. Background technique [0002] The mixer is a direct equipment for mixing materials. Its function is to mix the prepared materials into a mixture that is uniform and meets the quality requirements. According to the working principle, it can be divided into two categories: self-falling mixers and forced mixers. The self-falling mixer is to put the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum lift the mixture to a certain height, and then freely scatter it down 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 consumable parts are small, but the mixing intensity is not violent enough. ...

AI Technical Summary

Problems solved by technology

When the existing mixing device is working, the speed near the center of the mixing drum is low, and the speed at the wall of the drum is high, which makes the uniformity of different annular zones in the mixing drum different, which in turn leads to the central part of the mixing drum becoming a low-efficiency mixing area. The fluidity of the inner mixture is poor, and it is easy to adhere to the stirring shaft, resulting in shaft holding phenomenon

At present, there have been researches on this problem: such as a coupling synchronous twin-shaft vibrating mixer proposed by patent CN201110350970.0 and a forced vibrating mixer proposed by patent CN201520294130.0. Shafts are nested to achieve vibration. The scheme mentioned in the study has a complex structure, and the agitator shaft will cause serious damage to the transmission system during the vibration process, and the reliability is low.
