Liquid storage supply device

Abstract

The invention discloses a liquid storage supply device. The liquid storage supply device comprises a liquid output mechanism, a first liquid storage box, a second liquid storage box, a first pump body, a first liquid supply pipeline, a first oil returning pipeline, a second pump body, a second liquid supply pipeline, a second oil returning pipeline, a first electromagnetic valve and a second electromagnetic valve. Through opening or closing of the first electromagnetic valve and the second electromagnetic valve, the first pump body or the second pump body is controlled to pump liquid in the liquid storage boxes to the corresponding liquid supply pipelines, the liquid is further input to the liquid output mechanism, meanwhile, through opening or closing of the first electromagnetic valve and the second electromagnetic valve, and remaining liquid in the liquid output mechanism is recycled to the corresponding liquid storage boxes through the corresponding liquid returning pipelines. According to the liquid storage supply device, switching use of at least two kinds of liquid can be achieved, meanwhile, the device does not need to clean the whole device, only the liquid output mechanism needs to be cleaned, labor intensity of persons can be reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of liquid delivery, in particular to a liquid storage and supply device. Background technique [0002] In many manufacturing activities, the addition and transportation of liquid auxiliary materials are involved, mainly for the storage and supply of a single liquid auxiliary material, that is, a single container and a single delivery circuit constitute a circular delivery of liquid auxiliary materials. [0003] However, with the innovation of the production process, it is necessary to switch between different liquid auxiliary materials in the process of the product. In the existing technology, in order to meet the requirements of the traditional process, only a single container and a single delivery circuit are generally used to transport the liquid auxiliary materials. When a new process needs to be used to switch liquid auxiliary materials, it is necessary to discharge different liquid auxiliary materials ...

Problems solved by technology

[0003] However, with the innovation of the production process, it is necessary to switch between different liquid auxiliary materials in the process of the product. In the existing technology, in order to meet the requirements of the traditional process, only a single container and a single delivery circuit are generally used to transport the liquid auxiliary materials. When a new process needs to be used to switch liquid auxiliary materials, it is necessary to discharge different liquid auxiliary materials in the equipment, clean the equipment as a whole, and then add the required liquid auxiliary materials for use. This process requires a lot of manpower and material resources. At the same time, Inadvertent cleaning of containers and paths can also affect the purity of liquid excipients and affect process quality
