Problems solved by technology

From the 1990s to the present, autoclave explosion accidents have occurred almost every year, causing casualties
Through the investigation and analysis of many autoclave accidents, it is known that the common point of these accidents is that the kettle teeth slipped or were damaged, resulting in an explosion, and the lack of effective quick-opening interlock device or damage to the interlock device was the primary cause of the kettle tooth slipping
[0004] At present, there are many types of interlocking devices for quick-opening pressure vessels in China. Although some interlocking devices can meet the requirements stipulated in Article 3.20 of the "Safety Technology Supervision Regulations for Stationary Pressure Vessels" TSGR0004-2009, because autoclaves are generally used in In the building materials industry, the harsh production environment, frequent opening and closing of the kettle door, and irregular operations by operators can easily lead to damage to the interlock device.
However, some interlocking devices with high reliability in foreign countries are difficult to be popularized and applied due to reasons such as complex structure, low production efficiency, high price, and high maintenance cost.

Abstract

The invention discloses a safety interlocking device of a still kettle door quick to open. The safety interlocking device is characterized in that the safety interlocking device comprises a mechanical locking mechanism and a self-locking mechanism; the mechanical locking mechanism comprises a support, a semi-circular plate, a handle, a transmission part and a limiting part, and the support is fixed onto a kettle body; the transmission part comprises a transmission shaft and a connecting rod, the transmission shaft is connected with the semi-circular plate, one end of the connecting rod is connected with the semi-circular plate in a hinged mode, and one end of the handle is connected with the semi-circular plate; the limiting part comprises a limiting bolt, a limiting groove and a shaft sleeve, the limiting bolt is connected with the other end of the connecting rod in a hinged mode, the shaft sleeve is arranged on the kettle body, the limiting groove is formed in a kettle ring of the still kettle, and the limiting bolt penetrates through the shaft sleeve to be connected with the limiting groove in a clamped mode after the semi-circular plate is rotated in place. The safety interlocking device of the still kettle door quick to open has the advantages of being safe, reliable, high in automation degree, low in manufacturing cost, firm, durable, simple to operate and convenient to repair.

Description

technical field [0001] The invention relates to a safety interlock device, in particular to a safety interlock device for quick opening of an autoclave door. Background technique [0002] A quick-opening pressure vessel refers to a vessel with a nested quick-sealing locking device between the end cover or the head and the main body of the access to the vessel. The quick-opening door safety interlock device is a safety interlocking device used to prevent accidents due to the quick-opening door not being closed to the designated position before boosting operation or opening the quick-opening door before the internal pressure of the container is fully released. [0003] In recent years, autoclaves with toothed structure have been widely used, and a large number of newly installed autoclaves are put into use every year, but the frequent occurrence of autoclave accidents follows. From the 1990s to the present, autoclave explosion accidents have occurred almost every year, result...
