Constant-temperature stirring tank

Abstract

The invention relates to a novel stirring tank. The stirring tank comprises a tank body, a tank cover, a feeding opening, a discharging opening, a drain outlet, a stirring shaft, a bearing, a sleeve, stirring teeth, a scraper, a clamping sleeve, heating liquid or cooling liquid inlet, a heating liquid or cooling liquid outlet and a temperature controller, wherein the stirring tank is configured to drive the stirring teeth and the scraper connected to the stirring teeth to rotate so as to stir the materials through the stirring shaft connected to the bearing and remove material liquid adhered to the tank wall during stirring; the temperature of the material liquid can be well controlled in a small range through the cooperation between the temperature controller and the clamping sleeve. Through the stirring tank disclosed by the invention, the stirring process is optimized, simultaneously the waste and degeneration of the materials are avoided and the production efficiency and the product quality are improved.

Description

technical field [0001] The invention relates to a constant temperature stirring tank, which belongs to the field of stirring devices. Background technique [0002] The mixing tank is a kind of equipment that mixes the materials evenly by stirring. It mainly uses the stirring shaft to drive the rotation of the stirring teeth to mix the materials. At present, in the mixing tank used in domestic production, during the mixing process, due to the different viscosity and physical properties of the material, and the fluctuation of the liquid level of the material, a large amount of material often sticks to the tank wall. If it is not cleaned in time, It will cause material waste, especially when the stirring process is accompanied by heat conduction such as heating or cooling, the material sticking to the tank wall will also increase the thermal resistance of the tank wall, and the material on the tank wall will be exposed to high temperature or The low temperature properties will...

AI Technical Summary

Problems solved by technology

At present, in the mixing tank used in domestic production, during the mixing process, due to the different viscosity and physical properties of the material, and the fluctuation of the liquid level of the material, a large amount of material often sticks to the tank wall. If it is not cleaned in time, It will cause material waste, especially when the stirring process is accompanied by heat conduction such as heating or cooling, the material sticking to the tank wall will also increase the thermal resistance of the tank wall, and at the same time, the material on the tank wall will be exposed to high temperature or The low temperature properties will also change to a certain extent, and subsequent contact with the materials in the tank may lead to a decrease in the quality of the entire batch of materials

Therefore, in the existing production process, in most cases, the material sticking to the tank wall during the mixing process is manually cleaned, which not only takes time and effort and is difficult to clean up, which affects production efficiency, but also affects the material balance in the production process, etc. Process calculations make a difference

For some sealed tanks, it is even more impossible to achieve

In addition, when some materials containing fine particles are produced now, when the materials are stirred, the materials can easily enter the bearing from the gap between the stirring shaft and the bottom of the tank, thereby damaging the bearings, reducing the service life of the mixing equipment, and increasing the Cost of production

In addition, although the existing mixing tank has heating or cooling steps, the temperature control cannot be very precise. For some biological and chemical products that require a relatively high temperature, improper temperature control will cause the biological products to deteriorate, and also Will increase the side reactions of chemical products
