High-capacity K-type composite glass-lined reaction pot and manufacturing method thereof

Abstract

The invention provides a high-capacity K-type composite glass-lined reaction pot and a manufacturing method thereof, which belongs to first / second-class pressured-vessel reaction equipment used in the chemical engineering or pharmaceutical industry. The K-type composite glass-lined reaction pot is characterized in that the capacity of the reaction pot is over 10 kilolitres; the inner wall of an inner tube body of a pot body is coated with a glass-lined enamel layer; and the inner wall of a pot cover is lined with organic material. The method has the advantages that the method initiates that the manufacture of iron blank comprehensively meets the standard of pressured vessels; an outer jacket is an integral-structure piece and is welded to the inner tube body so as to form the pot body; the thickness of a steel plate of the outer jacket increases by 2 to 6 millimeters according to the standard of the prior design; the outer wall of the outer jacket is coated with an enamel layer; by applying a multifunctional temperature-control precision inner-heating type electric furnace and implementing a novel enamel firing process of combining the hoisting and autorotation of a glass-lined pot body, the glass-lined pot body of which the surface of a big flange of a pot mouth is nearly free from deformation can be repaired and reused after the glass-lined pot body is damaged; as the inner wall of the pot cover is lined with the organic material and the outer wall of the pot cover is sprayed with KTS enamel, the pot cover is high in manufacture precision, durable and easy to repair; a stirring blade propeller is enlarged; production efficiency is improved; the invention promotes the important development of the prior Chinese Standard to overtake international technical standards; and the method and the pot have extremely remarkable economic benefit and social benefit.

Description

technical field [0001] The invention relates to a kind of reaction equipment belonging to the first and second types of pressure vessels used in chemical industry and pharmaceutical industry. In particular, it refers to a large-capacity K-type composite glass-lined reaction tank and a manufacturing method thereof. technical background [0002] At present, the firing of glass-lined reaction tanks at home and abroad is all externally heated kilns. The iron blank is made of secondary molding. jacket. The product has been baked at a high temperature of about 900°C for many times, resulting in the overall deformation of the tank body. The larger the capacity, the greater the deformation of the large flange surface of the tank mouth. Reduce the diameter of the mouth of the tank to improve the sealing performance. [0003] For this type of large-capacity F-type glass-lined reaction tank that is not manufactured according to the capacity specification, it cannot be repaired after...
