Abstract
The utility model relates to a mechanical sealing device of a reaction kettle. The mechanical sealing device of the reaction kettle comprises a lower sealing cover, a sealing ring, a cooling device, an upper sealing cover, an anti-corrosion ring, a fixation ring and an abrasion-resistant sleeve. The lower sealing cover is fixedly connected to the reaction kettle. The cooling device is fixedly connected to the lower sealing cover. The sealing ring is arranged between the lower sealing cover and the cooling device. The cooling device is provided with a cavity and a circulation water opening. The upper sealing cover is fixedly connected to the top of the cooling device. A groove is formed in an inner ring of the upper sealing cover and connected with the corrosion-resistant ring in a matched mode. The abrasion-resistant sleeve is arranged on the top of the upper sealing cover. The abrasion-resistant sleeve is fixed through the fixation ring which is fixedly connected to the top of the upper sealing cover. According to the mechanical sealing device of the reaction kettle, in the use process, circulation water can be used for lowering the mechanical seal temperature, so that the mechanical sealing service life is prolonged, part of overflowing gases is cooled and reaction safety is improved.
