[0001] The utility model relates to the technical field of pressure relief walls, in particular to an assembled and detachable pressure relief wall. Background Art

[0002] In recent years, with the improvement of national security awareness, the explosion-proof problem of large factories with potential explosion hazards has gradually attracted widespread attention from all walks of life. How to minimize casualties and property losses after an explosion has become an urgent problem that needs to be solved. Therefore, pressure relief walls came into being.

[0003] Pressure relief wall, also known as explosion relief wall. As a lightweight wall of pressure relief facilities, the unit mass should not be greater than 0.6KN / ㎡. Explosion relief wall is a device that can instantly release the critical pressure explosion pressure to provide indoor explosion and explosion pressure. It is mainly used in the pressure relief of explosive areas such as petrochemical industry and coal mining industry and gas fire protection areas. When an explosion occurs inside, it can quickly release the huge impact pressure inside and reduce the personal injury and property loss caused by the explosion.

[0004] At present, the existing pressure relief wall is troublesome to install due to the presence of multiple pressure relief plates, and the pressure relief plates will be damaged after the pressure relief, and need to be replaced with new ones for use, and cannot be reused, resulting in high cost of use.

[0005] Therefore, those skilled in the art provide an assembled and detachable pressure relief wall to solve the problems raised in the above background technology. Utility Model Content

Due to the impact force, the opening fan 3 rotates upward to open and complete the pressure relief, and the explosion impact pressure is released in time to complete the pressure relief function. After the pressure relief is completed, the opening fan 3 can be reused after slight trimming. Two detachable hinges 5 are arranged above the opening fan 3, which can facilitate the disassembly and assembly of the opening fan 3. When the equipment needs to be taken out of the equipment room for maintenance, the detachable pressure relief wall can be easily removed. After the equipment is repaired and enters the equipment room, the detachable pressure relief wall can be installed again, so as to meet the requirements of repeated disassembly and use. The detachable opening fan 3 is welded with 1.2mm steel plate, and its cavity is filled with fireproof and sound insulation cotton 7, which can effectively soundproof and ensure that no large noise pollution is generated. It can also absorb and isolate the heat generated during the explosion to avoid a large impact of the explosion. Electrostatic spraying is used on the surface of the detachable pressure relief wall to make the paint on its surface more uniform and the use effect better.
