Description

Technical Field

[0001] The utility model relates to a cleaning auxiliary lifting device, belonging to the field of reaction tank auxiliary equipment. Background Art

[0002] Reaction tanks and fermentation tanks are containers for chemical and physical reactions. The tanks need to be cleaned before and after fermentation. The volume of industrially produced tanks is at least 500L. Therefore, when cleaning the tanks or conducting sampling tests, auxiliary devices that can be lifted and lowered are required to assist in lifting the cleaning equipment or tanks.

[0003] For example, the prior art application number is CN202121705387.2, and the name of the patent application is a stainless steel reaction tank, which discloses that it includes a base, a reaction tank lifting mechanism, a driving mechanism and a stirring mechanism. When the device is working, the reaction tank is placed on the base, and the lifting mechanism and the driving mechanism are adjusted to match according to the amount of liquid in the reaction tank. After the adjustment, the first motor is started, and the stirring mechanism works. The cooperation of the driving mechanism and the lifting mechanism maximizes the effect of the stirring mechanism, which can be dynamically adjusted according to the liquid in the reaction tank, and the materials after the reaction can be transferred with the reaction tank, which is convenient for transportation.
