Multi-shaft mortar and high-viscosity fluid stirrer for axial turbulent flow pattern multi-wire cutting machine

Abstract

The invention discloses a multi-shaft mortar and high-viscosity fluid stirrer for an axial turbulent flow pattern multi-wire cutting machine, comprising a plurality of single shaft stirring units which have the same structure and are uniformly arranged in a pot body of a stirring pot along the circumferential direction, each single shaft stirring unit comprises a stirring shaft arranged vertically, a stirring assembly and a driving mechanism, the stirring assemblies are coaxially installed at the bottom end of the stirring shaft and comprise impellers and short flow division tubes, the short flow division tubes are used for restricting a material flow direction to an axial movement along the stirring shaft, the impellers and the short flow division tubes are assembled into the stirring assembly which drives the material needed to be mixed and stirred to do an axial turbulent flow motion, the impellers are coaxially installed at the bottom end of the stirring shaft, and the short flow division tubes are coaxially sleeved at the outer sides of the impellers. The multi-shaft mortar and high-viscosity fluid stirrer has the advantages of simplicity in structure, high stirring ability, small shearing force, high dispersing power and high effect, and can be used for solving the problem that silicon carbide is broken due to the shearing force during the high-speed stirring of various traditional stirrers. Moreover, a stuck phenomenon is difficult to generate.

Description

technical field [0001] The invention relates to a multi-shaft agitator, in particular to a multi-shaft agitator for axial turbulent flow type multi-wire cutting machine mortar and high-viscosity fluid. Background technique [0002] The cutting mortar for multi-wire cutting machine is a high liquid-solid ratio of up to 1:0.95, that is, a high-viscosity suspension, and the solid silicon carbide of the suspension must have good dispersion during actual cutting. At the same time, the solid silicon carbide is very uniformly suspended in the cutting fluid to form a cutting mortar. And during the stirring process of the slurry, it is necessary to avoid violent stirring to cause the silicon carbide particles to be sheared and broken to affect their cutting performance. In the traditional mortar mixing tank for multi-wire cutting machine, the agitator is mostly a paddle or frame agitator. During the mixing process, the fluid flow pattern is generally radial movement, and the fluid f...

Problems solved by technology

In the actual production process, in order to increase the production output of the multi-wire cutting machine, it is necessary to install multiple mortar mixing tanks, which puts forward new requirements for factory buildings, and various costs will increase accordingly

[0003] In addition, in the chemical industry, daily necessities industry, mining industry and other industrial fields, there is also an urgent need to research and develop a fluid agitator that can uniformly stir high-solid-liquid ratio and high-viscosity fluids, especially in the flotation process in the mining industry. The different particle sizes of the solids put in at one time can easily cause the agitator to be stuck. How to prevent large solids from entering the agitator and blocking the agitator, people have to use various screens to achieve
