Easy-to-open inspection door of high-temperature airtight equipment

Abstract

The invention relates to an easy-to-open inspection door of high-temperature airtight equipment. The inspection door comprises a door frame and a movable door, the door frame is installed on the outerside of an outlet of an equipment shell body, and the middle of the door frame is a hollow inspection door pipeline; the movable door is arranged on the outer portion of the inspection door pipeline,the movable door is hinged with the door frame, which is used for opening or closing the inspection door pipeline, and a thermal-protective layer is arranged on the portion, located on the outer sideof the inspection door pipeline, of the door frame; a sealing device is further arranged between the movable door and the door frame, and when the movable door is closed, the sealing device is used for sealing a gap between the movable door and the door frame. Three sealing structures are adopted, the first sealing structure adopts a custom-made hasp capable of resisting high temperature and highstrength, after the movable door is closed, a U-shaped foaming sealing strip is tightly pressed, the locking is firm, and the hasp can be conveniently opened; the second sealing structure adopts a wool felt capable of resisting high temperature, and dust generated in the process of transporting loose materials can be sealed; the third sealing structure adopts temperature-resistance and flexible asbestos, particle materials can be sealed, and the influence of high-temperature air in a cavity body on the previous two sealing measures is avoided.

Description

technical field [0001] The invention relates to the field of inspection doors, in particular to an easy-open inspection door for high-temperature airtight equipment. Background technique [0002] Buried scraper conveyors, bucket elevators, and screw conveyors have become a widely used bulk material conveying equipment. They are very mature in theory, design, manufacture, and application. They are widely used in metallurgy, building materials, electric power, chemicals, cement, Coal and other industries. [0003] With the improvement of application technology and the continuous in-depth development of various industries, the requirements for equipment are also increasing, especially in the fields of building materials, chemical industry, coal chemical industry, etc. There are relatively complex working conditions, and its main characteristics are High temperature, dusty, and need to prevent gas leakage from the material running system. Therefore, the buried scraper conveyor...
