Description

Technical Field

[0001] This utility model relates to the technical field of enamel-lined reactor equipment, and in particular to a novel sealing structure for an enamel-lined reactor. Background Technology

[0002] Enameled reactors are composite material products formed by lining the inner surface of a steel container with high-silica glass, which is then firmly adhered to the metal surface after high-temperature firing. They combine the stability of glass with the strength of metal, exhibiting excellent corrosion resistance. Enameled reactors are widely used in chemical, petroleum, pharmaceutical, pesticide, and food industries, and are suitable for corrosive environments containing various organic acids, inorganic acids, and organic solvents.

[0003] In the prior art, according to Chinese patent application number CN202222704191.2, a reaction vessel sealing structure is disclosed, which includes a reaction vessel body and a reaction vessel cover body that fastens to the reaction vessel body. The upper port of the reaction vessel body extends radially and has a lower edge. The reaction vessel cover body has an upper edge that engages with the lower edge. The upper port of the reaction vessel body extends upward to form an inner extension portion. A sealing ring groove is provided on the inner extension portion. A sealing ring is provided in the sealing ring groove. The opening of the sealing ring groove faces the outside of the reaction vessel body. The reaction vessel cover body includes an inner sidewall that fastens to the outside of the inner extension portion. The sealing ring groove and the inner sidewall form a sealing space. The reaction vessel sealing structure provided by this utility model solves the problem that the sealing ring of the existing reaction vessel sealing structure will fall off after one use and cannot be reused.

[0004] In the prior art, according to Chinese patent application number CN202222704191.2, a sealing structure for a reactor is disclosed. This structure reduces the corrosion of the sealing ring by shielding it inside the equipment. However, the upper and lower sides of the sealing ring are in direct contact with the equipment, which increases the wear intensity of the sealing ring and affects its service life. Therefore, we propose a novel sealing structure for an enamel-lined reactor to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies. According to Chinese Patent Application No. CN202222704191.2, a sealing structure for a reaction vessel is disclosed.

[0021] 1. By setting up a flexible sealing ring and sealing unit, the sealing element is divided into three layers, with the middle layer being flexible and the top and bottom layers being metal. While ensuring sealing performance, this reduces wear on the sealing element, improves buffering performance, and extends the service life of the equipment.

[0022] 2. By setting positioning rings and positioning blocks, the seals can be disassembled and replaced or repaired later, while also making the installation of the seals more stable. Attached Figure Description
