Chemical mixing device capable of stirring in continuous variable-diameter mode

Abstract

The invention discloses a chemical mixing device capable of stirring in a continuous variable-diameter mode. The chemical mixing device comprises a bottom plate, a vertical plate, a top plate and a stirring barrel, wherein a support is arranged at the upper end of the top plate, a horizontal shaft is arranged on the support, further the horizontal shaft is movably connected with the support, one end of the horizontal shaft is connected with a driving motor arranged on the support, a vertically downward rotating shaft is in rotary connection with the top plate, the top end of the rotating shaft is connected with one end of the horizontal shaft through a gear mechanism, a vertical rod is vertically arranged in the stirring barrel, a rotary sleeve is arranged on the outer side of the vertical rod, the lower end of the rotating shaft is connected with the top end of the rotary sleeve through a transmission mechanism, at least two stirring assemblies are arranged on the rotary sleeve, the horizontal shaft is further provided with a cam, and the cam is connected with the vertical rod through a slide mechanism. The chemical mixing device disclosed by the invention is simple in structure, can stir in the continuous variable-diameter mode and has higher stirring efficiency and better stirring effect, and the stirring barrel can be cleaned.

Description

technical field [0001] The invention relates to a chemical machinery, in particular to a chemical mixing device capable of continuous variable-diameter stirring. Background technique [0002] In chemical production, in order to process raw materials into finished products of a certain specification, a series of chemical processes such as raw material pretreatment, chemical reaction, and reaction product separation and purification are often required. The machinery used to realize these processes is often classified as chemical machinery. ; Stirred tank reactors are often used in the processing of chemical raw materials. The stirring diameter of the material stirring in the traditional reactor cavity is constant, so the stirring efficiency for different parts is the same, but the mixing degree or viscosity of raw materials in different parts is different, resulting in uneven mixing of raw materials, which affects Stirring effect and mixing efficiency. At the same time, after...

AI Technical Summary

Problems solved by technology

The stirring diameter of the material stirring in the traditional reactor cavity is constant, so the stirring efficiency for different parts is the same, but the mixing degree or viscosity of raw materials in different parts is different, resulting in uneven mixing of raw materials, which affects Stirring effect and mixing efficiency. At the same time, after the mixing is completed, the mixing drum is generally difficult to clean and there are residues left, which will affect the next mixing and stirring.
