Abstract
A novel special anti-explosion valve for a folded plate relates to the technical field of dust catchers and comprises a door frame (1), a door cover (2), a door cover support (3), a hinge pin (4) and a supporting lug (7). The door cover support (3) is arranged on the outer wall at the upper end of the door cover (2) and rotatably connected with the supporting lug (7) by the hinge pin (4), the hinge pin (4) is fixedly connected with the supporting lug (7) by a cotter pin (6) and a flat gasket (5), the upper end of the door cover (2) is connected with that of the door frame (1), and the lower end of the door cover (2) is connected with the middle of the door frame (1). The novel special anti-explosion valve for a folded plate is simple in structure, flexible in running and fine in sealing performance, can solve the problem of potential safety hazards of dust explosion and avoids damaging equipment and injuring personnel.
Description
Technical field:
The utility model relates to the deduster technical field, is specifically related to the special-purpose explosion-proof valve of a kind of novel flap.
Background technique:
Deduster is a facility commonly used in boiler and the industrial production, but the aluminium powder explosive dust is under certain concentration, probably blasts under the situation that runs into spark or static or burns.In order to solve this defective, dedusting bag adopts the Nomex industrial filter cloth precision with electrostatic-proof function to make usually and forms, cloth bag can be pulled down easily to clean and re-use, and this filter bag all carries out reliable ground in installation process, can avoid effectively because static causes the possibility of aluminium powder blast.
But dust explosion is than combustible substance and inflammable gas complexity, and usually, ignitable dust is suspended in the dust cloud that is formed in the air in the explosion ratio scope, and under the incendiary source effect, a little fireball is at first lighted and form to the part dust that contacts with incendiary source.Under the warm amount effect that this little fireball burning is emitted, close on around making that dust is heated, temperature raises, the combustion phenomena of catching fire produces, fireball just will enlarge and form dust explosion rapidly like this, and that blasts is greatly dangerous.General explosion precaution can not solve such potential safety hazard.
The model utility content:
The purpose of this utility model provides the special-purpose explosion-proof valve of a kind of novel flap, and it is simple in structure, goes slick, and good seal performance can solve the potential safety hazard of dust explosion, avoids causing equipment and personnel's injury.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it is made up of doorframe 1, door closure 2, door closure supporting bracket 3, bearing pin 4 and support pad 7, the upper end outer wall of door closure 2 is provided with door closure supporting bracket 3, door closure supporting bracket 3 is rotatably connected by bearing pin 4 and support pad 7, bearing pin 4 is fixedlyed connected with plain cushion 5 by cotter pin 6 with support pad 7, the upper end of door closure 2 is connected with the upper end of doorframe 1, and the lower end of door closure 2 is connected with doorframe 1 middle part.
The upper outside of described doorframe 1 from inside to outside is disposed with rubber sheet gasket 11, rectangle burst disk 9, clamping flange 8, and rubber sheet gasket 11, rectangle burst disk 9 and clamping flange 8 are by screw bolt 10 riveted joints.
When the utility model is installed, doorframe 1 and deduster housing are fixed, be welded with flange 14 between the lower end of doorframe 1 and the housing of deduster.Bearing pin 4 rotates flexibly, guarantees that door closure 2 can smooth opening, when door closure 2 is closed, with the good airproof performance of doorframe 1.
The utility model is simple in structure, goes slick, and good seal performance can solve the potential safety hazard of dust explosion, avoids causing equipment and personnel's injury.
