Pressure relief device for explosion-proof workshop

Abstract

The invention belongs to the technical field of workshop pressure relief, and particularly relates to a pressure relief device for an explosion-proof workshop. The pressure relief device comprises a plurality of groups of pressure relief modules mounted on a roof. According to the pressure relief device, four designed water leakage-proof shells wrap the positions where four triangular baffles arein contact with one another in a matched mode, in rainy days, due to aging of sealing strips, rainwater which can enter through the positions where the four triangular baffles are in contact with oneanother in the matched mode can flow into mounting blocks on the lower side through the four water leakage-proof shells, and flows into the roof from drainage holes in the mounting blocks to be drained, so that the rainwater is prevented from flowing into the workshop from the positions where the four triangular baffles are in contact with one another in the matched mode, and the pressure relief roof has a rainproof function. Each pressure relief unit is provided with a swing sensing structure, the windward direction can be flexibly and freely adjusted according to the wind direction, and windvibration is reduced.

Description

[0001] Technical field [0002] The invention belongs to the technical field of pressure relief for factory buildings, and in particular relates to pressure relief equipment for explosion-proof factory buildings. Background technique [0003] Explosion-proof factory building refers to the factory building with explosion hazard or the factory building with explosion hazard parts in the factory building; the explosion-proof factory building should be equipped with pressure relief facilities. [0004] The current explosion-proof plant has the following problems: [0005] First, the setting of pressure relief equipment such as pressure relief windows and pressure relief roofs has a relatively high damage limit in the event of an explosion, which still causes certain damage to the factory building; such as explosion relief windows, which use steel window frames and are equipped with special Hinges, pressure relief devices and other hardware accessories; when the air pressure diffe...

AI Technical Summary

Problems solved by technology

[0005] First, the setting of pressure relief equipment such as pressure relief windows and pressure relief roofs has a relatively high damage limit in the event of an explosion, which still causes certain damage to the factory building; such as explosion relief windows, which use steel window frames and are equipped with special Hinges, pressure relief devices and other hardware accessories; when the air pressure difference inside and outside the building reaches a certain value, the explosion relief bolts of the pressure relief window will automatically fall off, the window sash will automatically open, and the pressure will be discharged outward; however, the explosion relief bolts need a certain pressure to fall off. Before the pressure value is reached, the factory building needs to bear the pressure change in the factory building before the pressure relief window is opened, causing certain damage to the factory building

[0006] Second, the explosion venting equipment on the wall is relatively unsafe compared with the explosion venting equipment on the roof. The roof is on the factory building, and it will generally not cause secondary harm to people during pressure relief, but the pressure relief equipment on the roof must consider strong wind and The impact of rainwater will not be blown away in strong winds, and will not leak when it rains. The existing equipment is mainly designed with pressure relief in mind. It is not considered in the design of strong winds and rain leakage, but only during installation. Through reliable installation and sealing, the effect of wind resistance and rain prevention can be obtained. After a long time of use, due to the aging of the gasket and the vibration caused by the wind, the fixation will not be firm and the rain will leak.
