Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of rupture disc clamping equipment, and particularly relates to a rupture disc clamping device for mine engineering. BACKGROUND

[0002] Mine engineering is an engineering technology science based on mineral resources, which carries out resource mining operation in a mine. It includes ground and underground engineering. Ground engineering mainly includes mining machinery and equipment and facilities, such as a concentrator, a shaft tower, a hoist, a pressure fan, a ventilator and the like. In the mining process of mine engineering, a rupture disc is often used in mining equipment to monitor the pressure of the equipment and prevent overload and explosion. The rupture disc is also called an explosion-proof disc or an explosion-proof membrane. It uses the rupture of the membrane to release pressure. After the pressure is released, the container is forced to stop running.

[0003] In the prior art, some existing rupture disc devices are composed of a rupture disc and a clamp. Usually, two clamping parts are fixed by bolts and connecting plates. However, due to different specifications of the rupture disc, some clamping parts can only position a single size of the rupture disc, thus having certain limitations. In addition, when some clamping parts clamp and fix the rupture disc, the bolts are usually tightened for fixation, and the state of the rupture disc in the clamping process cannot be observed. When the clamping force is too large, the rupture disc may be deformed or damaged, reducing its sensitivity and even causing it to fail. UTILITY MODEL CONTENT
