Dead-corner-free eccentric variable-blade-length stirring device

Abstract

The invention discloses a dead-corner-free eccentric variable-blade-length stirring device which comprises a barrel. A stirring shaft is arranged in the barrel, the stirring shaft and the center axis of the barrel are eccentrically arranged, an upper stirring mechanism and a lower stirring mechanism which are perpendicular to each other are fixed to the stirring shaft, and the upper stirring mechanism and the lower stirring mechanism are identical in structure. The upper stirring mechanism and the lower stirring mechanism both comprise a sleeve and a telescopic rod. The closed ends of the sleeves are installed on the stirring shaft through threads, the other ends of the sleeves are open, cavities are formed in the sleeves, and the telescopic rods are disposed in the cavities in a sliding mode. The ends, far away from the sleeves, of the telescopic rods are provided with grooves, and sliding assemblies are installed at the open ends of the grooves. A sliding rail matched with the sliding assemblies is installed on the inner wall of the barrel. The lengths of the upper stirring mechanism and the lower stirring mechanism are changed all the time along with stirring. The center of relative stirring of the upper stirring mechanism and the lower stirring mechanism is not the center axis of the barrel any more, the maximum stirring radius can be larger than the radius of the barrel, and the effect of liquid is better.

Description

technical field [0001] The invention relates to a stirring device, in particular to an eccentric variable blade length stirring device without dead angle. Background technique [0002] In some traditional industrial production, stirring devices are often used. Its main function is to stir the liquid, dissolve the materials in the liquid, or mix the mixed liquid raw materials. Although it is not necessary to assign them It can achieve the effect of thinking, but the experiment proves that the mixing or dissolving process is faster after the addition of stirring. From the traditional manual stirring to the current automatic mechanical stirring, the stirring device has been constantly innovating, but the current electric machinery The working principle of the stirring device is often very simple, and the stirring shaft is often installed at the center of the mixing barrel, or several stirring shafts symmetrical along the central axis of the barrel are arranged in the barrel, bu...

[0002] In some traditional industrial production, stirring devices are often used. Its main function is to stir the liquid, dissolve the materials in the liquid, or mix the mixed liquid raw materials. Although it is not necessary to assign them It can achieve the effect of thinking, but the experiment proves that the mixing or dissolving process is faster after the addition of stirring. From the traditional manual stirring to the current automatic mechanical stirring, the stirring device has been constantly innovating, but the current electric machinery The working principle of the stirring device is often very simple, and the stirring shaft is often installed at the center of the mixing barrel, or several stirring shafts symmetrical along the central axis of the barrel are arranged in the barrel, but these stirring devices work in the final analysis. The flow direction of the liquid in the body is symmetrical with respect to the central axis of the barrel, that is to say, there is the principle of central symmetry, but the flow law of the liquid flowing in the central symmetry is too simple. When all the liquid in the barrel is in the When flowing, there will be certain dead angles, and these dead angles are difficult to be stirred, which will have a certain impact on the final effect of stirring

Although the existing stirring device will try to solve the problem of stirring dead angle by adding stirring blades, but the increase of stirring blades will undoubtedly increase the probability of its damage, and it will also make the stirring device as a whole become bulky
