Aerated stirring apparatus for automatically controlling aeration volume

Abstract

The present invention relates to an aerated stirring apparatus for automatically controlling an aeration volume. The apparatus comprises a vessel body, an aerating structure, a controlling structure, and a stirring structure. The stirring structure comprises a stirring shaft, a power input structure of the stirring shaft that supplies power to the stirring shaft, and a plurality of stirring blades disposed on the stirring shaft and located within the vessel body. The aerating structure comprises a plurality of separate aeration lines. An inlet chamber, an aeration conduit with one end communicating with the inlet chamber, and an aeration manifold communicating with the other end of the aeration conduit form an aeration line. An electromagnetic valve is disposed on each aeration line to control an air intake volume. The controlling structure comprises a plurality of controllers. A probe of a dissolved oxygen device is fixed on each of the stirring blades. The ON / OFF of the corresponding electromagnetic valve is controlled by the controller according to a received signal of oxygen concentration. The apparatus can effectively control the problems of non-uniform gas delivery, high energy consumption, wasting gas resources, high costs, poor product quality, and low productivity in an amplified reactor.

Description

technical field

[0001] The invention relates to a stirring device, in particular to a ventilating stirring device, in particular to a ventilating stirring device which automatically controls the ventilation volume. Background technique

[0002] In the technical fields of chemical industry, food, medicine, etc., such as high-density fermentation, enzyme-catalyzed reaction with aerobic participation, chemical reaction with aerobic participation, etc., it is often necessary to consider the uniformity of material mixing and the dissolution efficiency of gas. The product quality and cost are inseparable from the reaction process. The speed of reaction and the degree of material conversion are directly affected by the material flow and mixing effect of stirring. In the reactor, the macroscopic process of volume circulation in a large range and the dynamic change of local small eddy flow are directly affected by the microscopic flow field. For the process with gas participation, th...
