Stirring system

Abstract

The invention provides a stirring system which comprises a stirring shaft, a flow guide device and a power mechanism; the flow guide device comprises a flow guide cylinder and a support component, andthe flow guide cylinder is arranged on the support component; the power mechanism comprises a power assembly and a power machine frame, and the power assembly is arranged on the power machine frame;the stirring shaft is circumferentially fixedly connected with the power output shaft contained in the power assembly; the stirring shaft is provided with a plurality of radial supporting structures,and the plurality of radial supporting structures are arranged in the length extending direction of the stirring shaft, and the stirring shaft is connected to one or more of any of structures such asthe flow guide cylinder, the supporting component and the power machine frame. The stirring system provided by the invention can be installed in a stirring tank, a separate fluid rising channel is formed, and the circumferential flow of a fluid during upward conveying is reduced, so that raw materials at the bottom can be effectively conveyed and stirred, and the stirring efficiency is improved.

Description

technical field [0001] The invention relates to the field of stirring, in particular to a stirring system, especially a stirring system capable of conveying materials upward. Background technique [0002] The agitator is a device for forced convection and uniform mixing of liquid and gaseous media. The type, size and speed of the stirrer have an effect on the distribution of the stirring power between the bulk flow and the turbulent pulsations. Generally speaking, the power distribution of the turbine agitator is favorable for turbulent flow fluctuations, while the propeller agitator is favorable for the bulk flow. For the same type of agitator, under the condition of the same power consumption, the agitator with large diameter and low rotation speed mainly consumes power in the overall flow, which is conducive to macroscopic mixing. [0003] Stirring equipment is generally composed of a stirring tank and an agitator, and the installation of the agitator includes a single-...

Problems solved by technology

[0004] In addition, for the raw materials located at the bottom of the mixing tank, in order to make them uniformly mixed, the prior art generally adopts two methods: one is to set up pipelines at the bottom of the mixing tank, and pump the raw materials to the top to continue stirring. The overall structure of the scheme is complicated, the cost is high, and it is not conducive to maintenance; the other is to directly set propeller blades or other curved surface blades in the stirring tank, such as the circulating mixer provided by the patent document CN104941486A, and the bottom raw materials are transported through the blades To the top, but due to the influence of liquid viscous force, the efficiency of upward transportation is not high, especially for large-scale mixing equipment, when the fluid moves upward, it is easy to flow in the radial or circumferential direction, and cannot achieve high Conveying and stirring effect
