A pressure vessel for adjustable compression glass-lined equipment

Abstract

The invention belongs to the technical field of glass lining equipment and particularly relates to an adjustable compression pressure container for glass lining equipment. The pressure container solves the problems of difficult dismounting of a sealing orifice and even rustiness and closing at a connector due to too tight compression. The pressure container comprises a pressure tank, wherein a thread groove is formed in a peripheral inner wall, close to the bottom, of the pressure tank; a cooling pipe is mounted in the thread groove in an embedded manner; a spiral thread rib is reserved on a peripheral outer wall of the pressure tank; four vertical support rods are welded at the top end of the pressure tank; two parallel channel steel slide rails are welded at the top ends of the support rods; and openings of the channel steel slide rails are opposite. According to the container, when an inner barrel suffers from a large sudden upward extrusion force, the extrusion force can be depleted slowly; a spring is more difficult to compress at last; finally, the spring is compressed to store energy to a certain extent and begins to be released; a counter force is generated to prevent a disc cover from being jacked up suddenly; and the safety performance of a device is improved.

Description

technical field [0001] The invention relates to the technical field of glass-lined equipment, in particular to an adjustable compression pressure vessel for glass-lined equipment. Background technique [0002] Glass-lined equipment is a kind of storage equipment made by applying enamel to the metal surface and firing it to make the enamel adhere to the surface of the metal iron tire. The equipment has the chemical stability similar to glass and the strength of metal. [0003] At present, glass-lined equipment has been widely used in the chemical industry due to its excellent acid resistance and alkali corrosion resistance. The safety of glass-lined equipment directly affects the smooth operation of chemical production. The main failure mode of glass-lined equipment is the peeling off of anti-corrosion glaze. According to production experience, if the glaze falls off near the non-sealed surface, it is often caused by manufacturing defects or sudden temperature changes in th...

AI Technical Summary

Problems solved by technology

According to production experience, if the glaze falls off near the non-sealed surface, it is often caused by manufacturing defects or sudden temperature changes in the equipment. However, it has been found that most of the defects or damage are located at the sealing junction near the opening. If the pressing is too tight, it will be difficult to disassemble the sealing port, and even the joint will be rusted and closed. Therefore, a pressure vessel that is easy to adjust the tightness is needed.
