Description

Technical Field

[0001] The utility model relates to the technical field of chemical material processing, in particular to a stirring device for a chemical material barrel. Background Art

[0002] As a standard container widely used in the chemical industry, 200L barrels are mainly used to hold and store various chemical products and raw materials. In actual applications, some chemical products may be stratified or precipitated after long-term storage, which seriously affects the product quality and performance; therefore, before using such products, they will be fully stirred with the help of built-in or external stirring devices to restore their uniformity.

[0003] However, for chemical products with high viscosity, due to the shear force of the stirring device during conventional stirring, it is very easy to introduce air into the product and form bubbles in it, which will not only destroy the stability of the product, but also cause the product performance to decline or even fail. To solve this problem, the container containing the chemical product is currently vacuumed before stirring to remove the air in the barrel and reduce the possibility of introducing bubbles during stirring.

[0004] However, conventional 200L barrels do not have sufficient structural strength to cope with the internal negative pressure caused by vacuuming due to their thin wall design. Vacuuming may cause the barrel body to deform, which will weaken the overall structural strength of the barrel body and affect the sealing of the barrel cover after the barrel cover is closed, resulting in a high damage rate for the barrel body, which in turn leads to higher production costs. If the material is transferred to a container or mixing equipment with sufficient strength for processing, although the problem of barrel deformation can be solved, it will increase additional costs and time consumption, especially in a mass production environment. Frequent material transfer and repackaging will lead to low production efficiency and high production costs. Utility Model Content
