Rotary active explosion venting mechanism

Abstract

The invention discloses a rotary active explosion venting mechanism, and belongs to the technical field of buffering damping devices for reducing explosion pressure in safety devices. In the mechanism, a fixed explosion venting impeller is arranged at the middle part of an explosion venting barrel. An angle motor fixedly connected to the fixed explosion venting impeller drives a rotation shaft torotate. A high-temperature-resisting bearing sleeving the rotation shaft is connected with the fixed explosion venting impeller. An explosion venting rotation impeller is fastened to the tail end of the rotation shaft through a fastening nut, a nut gasket and a bearing sleeve. A limiting sensor is arranged on the inner wall of the explosion venting barrel to detect the position and the rotation angle of the explosion venting rotation impeller. According to the rotary active explosion venting mechanism, an explosion venting channel can be rapidly opened and closed according to the detection result, symmetrically-distributed flame quenching holes are formed in the outer wall of the tail end of the explosion venting barrel, flames near an explosion venting port are reduced, explosion ventingpressure releasing is buffered, and damage to explosion venting equipment from secondary explosion is avoided. The rotary active explosion venting mechanism has the beneficial effects of being high inexecuting efficiency and safety, and the replacing and maintaining cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of buffering and damping devices for reducing explosion pressure in safety devices, and in particular relates to a rotary active explosion relief mechanism. Background technique [0002] At present, most explosion venting technologies adopt passive explosion venting, that is, the impulse and pressure generated by the explosion are used to activate explosion venting devices, such as explosion venting doors, bursting discs, and spring type explosion venting valves. Passive explosion venting technology does not require external force during explosion venting, saves energy, and can achieve effective explosion venting through reasonable structural design. However, the passive explosion venting technology belongs to post-explosion venting, and there are many unstable factors, which may easily cause accidents. Taking the bursting disc as an example, it requires the internal pressure of the equipment to reach a cer...

Problems solved by technology

The explosion venting door also has the same problem. The explosion venting process lags behind, and the blasting device cannot be started in time, which often results in the accumulation of internal pressure of the equipment and accidents.
