Salt making system vacuum deoxidation device and method

Abstract

The invention discloses a salt making system vacuum deoxidation device and method. The device comprises a deoxidation machine shell, a deoxidation machine base, a deoxidation machine upper cover, a sealing rubber ring, an electromagnetic lock, a control device, a gas device, a stirring device and a delivering device, the control device is arranged on one side of the deoxidation machine shell, thedeoxidation machine upper cover is arranged on the upper side of the deoxidation machine shell, the deoxidation machine base is arranged on the lower side of the deoxidation machine shell, the electromagnetic lock is arranged on the upper side of the control device, the gas device is arranged on the upper side of the deoxidation machine upper cover, and the sealing rubber ring is arranged on the lower surface of the inside of the deoxidation machine upper cover. The salt making system vacuum deoxidation device has the advantages that oxygen discharging can be accelerated by feeding inert gas in the process of vacuum deoxidation, full-automatic sensing of oxygen content, liquid information and air pressure information can be realized to realize full-automatic vacuum deoxidation processing operation of a salt making system, deoxidation efficiency is high, and operation is simple.

Description

technical field [0001] The invention relates to the field of salt production, in particular to a vacuum deoxidation device and method for a salt production system. Background technique [0002] Salt making is to make table salt (or industrial salt). The salt-making industry occupies an important economic position in the national economy and is an important part of the national economy. Vacuum deoxidation operations are required in the salt-making system. Nowadays, vacuum deoxidation is mostly assisted by heating steam, which has a large loss on the processing of finished products. And it does not have a fully automatic monitoring function. Compared with the Chinese patent application number 201310266140.9, a vacuum deoxidation method for a salt production system is disclosed, 1) heating the brine to 40-50°C and then entering the deoxidation system; 2) adjusting the absolute pressure of the deoxidation system to below 0.01MPa, so that The brine solution in step 1) is in a b...
