Description

A hydrolysis kettle liquid level detection device for indole production Technical Field The utility model relates to the technical field of indole production, in particular to a liquid level detection device of a hydrolysis kettle for indole production. Background Indole is a compound in which pyrrole is connected in parallel with benzene, also known as benzopyrrole. There are two modes of incorporation, known as indole and isoindole, respectively. Indole and its homologs and derivatives are widely found in nature, mainly in natural flower oils such as jasmine, bitter orange flower, narcissus, vanilla, etc., but in the medical field, indole has the effects of diminishing inflammation, resisting oxidation and regulating hormone balance, so that in the medical treatment process, indole solutions are often used for drug preparation, and in the production process, the indole hydrolysis processing is generally carried out in a hydrolysis kettle. When the hydrolysis kettle is used for carrying out indole hydrolysis, the liquid level change in the hydrolysis kettle needs to be concerned at any time, the blending proportion of indole and other materials is controlled, meanwhile, when the liquid level of a solution in the hydrolysis kettle is high, the first time is needed for excretion, excessive gas is prevented from being generated due to excessive internal reaction, the pressure is excessively high, and unnecessary safety risks are generated, but when the hydrolysis kettle is used for carrying out reaction, the indole possibly generates gas and consumes residual oxygen in the gas when encountering different substances, so that the pressure therein continuously changes, if the ordinary floating ball floats for carrying out liquid level detection, under the change of the pressure, errors occur under the conditions of the floating height of the floating ball and normal pressure, and the accuracy in recording the liquid level detection is influenced.
