Abstract

The utility model relates to an anti-explosion door with a magnetic-force suction disk. An outlet of an existing anti-explosion door body is additionally provided with a magnetic-force suction disk which is made from magnetic materials and is used as a doorway sealing surface. An iron sheet of the anti-explosion door is adsorbed on the anti-explosion door by magnetic force which is generated by the magnetic-force suction disk. The inner side and the outer side of the anti-explosion door are isolated and sealed. When the inner side of the anti-explosion door is provided with explosion and overpressure, the iron sheet overcomes the magnetic force of the magnetic-force suction disk under the action of pressure, is disengaged from the anti-explosion door and relieves pressure.

Description

The magnetic suction disc explosion proof door

The utility model relates to a kind of powder manufacturing apparatus explosion vent apparatus, the explosion proof door iron sheet utilizes magnetic force to be adsorbed in the explosion proof door outlet, makes the inside and outside isolating seal of explosion proof door, when explosion proof door inside detonation superpressure, the explosion proof door iron sheet overcomes magnetic force and breaks away from the doorway, makes the powder manufacturing apparatus pressure release.

At present, known powder manufacturing apparatus explosion proof door is with flange and bolt iron sheet to be fastened on the explosion proof door, need dismantle when changing iron sheet and return and adorn flange and bolt, has so just increased workload and working time, and has influenced the normal operation of equipment.

The purpose of this utility model provides a kind of explosion proof door, and it is not only according to there being the purposes of general explosion proof door, and the explosion proof door iron sheet need not flange and bolton, has reduced workload and the working time of changing iron sheet.

The purpose of this utility model is achieved in that in explosion proof door outlet and installs the magnetic suction disc made with magnetic material additional as the exit seal face that the explosion proof door iron sheet utilizes magnetic force to be adsorbed in the explosion proof door outlet.

Because adopt such scheme, explosion proof door not only has the purposes of general explosion proof door, and changes efficient and convenient.
