Device with multiple sets of vacuum systems being standby for each other

Abstract

The invention provides a device with multiple sets of vacuum systems being standby for each other, which belongs to the technical field of vacuum system application and comprises multiple sets of vacuum systems, multiple reaction kettles, a gas distribution cylinder and a standby vacuum system. In the multiple sets of vacuum systems, at least one vacuum pump is correspondingly arranged in each set of vacuum system; at least one standby vacuum pump is arranged in the standby vacuum system; an outlet in the top of the reaction kettle is in sealed connection with an air inlet of the air distribution cylinder through a conveying pipeline, and air suction ports of vacuum pumps in the vacuum systems are in sealed connection with an air outlet of the air distribution cylinder through conveying pipelines. And an air suction port of a standby vacuum pump in the standby vacuum system is hermetically connected with an air outlet of the branch air cylinder through a conveying pipeline. The device provided by the invention is used for solving the problems that the switching process is troublesome, the workload is large, the operation efficiency of the vacuum system is reduced, the operation stability of the reaction kettle is reduced, the production efficiency is reduced and the like under the condition that a set of vacuum system has problems.

Description

technical field [0001] The invention relates to the technical field of vacuum system application, in particular to a device in which multiple sets of vacuum systems serve as backups for each other. Background technique [0002] The vacuum system is generally used to vacuumize the reaction kettle, separator and other devices, so as to facilitate the physical and chemical reaction of materials, solid-liquid separation and other operations in a vacuum state. With the assistance of the vacuum system, vacuum feeding, vacuum degassing, Vacuum concentration and other processes. Vacuum system is one of the reaction auxiliary systems commonly used in food, biopharmaceutical, fine chemical and other industries, and is used to assist in the completion of process reactions such as vulcanization, alkylation, hydrogenation, condensation, and polymerization. [0003] For example, the current dimethyl water cracking device in the production of organic silicon uses a vacuum system to assist...
