Stirring device

Abstract

The invention provides a stirring device, comprising a stirring barrel, a main stirring shaft, an outer stirring unit and a stirrer, wherein the main stirring shaft is vertically arranged in the inner space of the stirring barrel; the outer stirring unit fixedly sleeves the main stirring shaft; the main stirring shaft is provided with a sliding groove; the stirrer is connected with the sliding groove; one side of the top end of the stirring barrel is provided with a feed inlet; a barrel cover is arranged above the feed inlet; the other side of the top end of the stirring barrel is provided with a temperature regulator; the outer wall of the stirring barrel is provided with a plurality of outwardly-extending radiating fins; the bottom end of the stirring barrel is provided with two discharge outlets which are symmetrically distributed at two sides of the main stirring shaft; the outer stirring unit comprises a top board; a cylindrical form wall surface is fixed below the top board and is provided with stirring teeth; the stirrer comprises vanes and a spindle sleeve; and the vanes are connected with the spindle sleeve. The stirring device provided by the invention has good heat radiation effect, can control stirring temperature, and realizes uniform stirring.

Description

technical field [0001] The invention relates to the field of heat preservation material preparation, in particular to a stirring device. Background technique [0002] The application range of thermal insulation materials in the field of construction is very wide. When preparing thermal insulation materials, it is necessary to stir the reactants. The stirring process is often accompanied by an exothermic process. Generally, during the reaction process, thermal insulation materials will have a limited temperature. , When the temperature is too high during stirring, the reaction will fail, and the stirring will be uneven. If the local temperature is too high, it will cause local explosion, which will cause a decrease in product quality and affect production.

[0002] The application range of thermal insulation materials in the field of construction is very wide. When preparing thermal insulation materials, it is necessary to stir the reactants. The stirring process is often accompanied by an exothermic process. Generally, during the reaction process, thermal insulation materials will have a limited temperature. , If the temperature is too high when stirring, the reaction will fail, and the stirring will be uneven. If the local temperature is too high, it will cause local detonation, which will cause a decline in product quality and affect production.

[0003] In the large-scale mixing equipment currently used, the stirring spindle is extremely easy to damage during use, the service life is short, and it is difficult to completely stir the liquid evenly when stirring some liquids with high density, and the stirring spindle will also be damaged during the rotation process. A lot of heat is generated, which makes the stirring device heat up and even affects the temperature in the container. Once the heat dissipation is not good, it will affect the normal use of the stirrer.
