Abstract
The utility model relates to industrial explosion-proof door equipment, particularly to an explosion-proof door for a wellhead of a coal mine inclined shaft. The explosion-proof door for the wellhead of the coal mine inclined shaft includes a door-frame rack, door leaves, reverse ventilation devices, thermal insulation layers, and the like, wherein the door-frame rack is divided into two bilaterally-symmetrical parts; an upright door frame is arranged between the two parts; the thermal insulation layers are arranged on the inner sides of the door leaves; the reverse ventilation devices are high-intensity magnets and installed on the door-frame rack and door leaf frames; and sealing pieces are fixed on the door-frame rack and the upright door frame. The explosion-proof door solves the common problems existing in the explosion-proof door of the wellhead of the conventional field inclined shaft that the explosion-proof door has no effect after explosion, can not reset rightly due to deformation, is liable to leak air, can not be closed automatically, requires manual closing operation, influences the normal operation of a ventilation system, and the like, has simple and compact structure and reliable seal, is convenient for maintenance, inspection and use, and is safe and reliable.
Description
Technical field
The utility model relates to mine explosion proof door equipment, refers more particularly to a kind of colliery slope mouth explosion proof door.
Background technology
Colliery inclined shaft explosion proof door is mounted in the air draft well head that main ventilation fan is housed.The present explosion proof door that uses, ubiquity complex structure, sealing were easily lost efficacy, the problem of easily leaking out, when normal the ventilation, barrier wells downstream and surface air fully; And when in a single day gas or dust explosion accident took place in the down-hole, difficulty can appear opening in traditional steel pipe plug, and air blast can't impact opens explosion proof door, does not have the release effect, thereby causes problems such as main ventilation fan and miscellaneous equipment damage; When the needs natural ventilation, need manually close, therefore, reliability is relatively poor, is badly in need of being improved.
Summary of the invention
In order to address the above problem, automatically close, and simple in structure, esy to use, safe and reliable explosion proof door exactly by energy proper reset, realization for goal of the invention of the present utility model.
The technical solution of the utility model is such, and a kind of colliery slope mouth explosion proof door comprises door frame 1, upright doorframe 2, door leaf 3, hinge 4, reversing device 6, insulation layer 10; Described door frame 1 is to form with the angle steel assembly welding, is divided into bilateral symmetry two parts, and there is a upright doorframe 2 centre; Described door leaf 3 is formed by Door leaf frame 7, door-plate 8, reinforcing rib 9 assembly weldings, and the inboard of door leaf 3 is provided with insulation layer 10; Be connected with hinge 4 between described door leaf 3 and the upright doorframe 2; Described reversing device 6 is a high strength magnet, is contained on door frame 1 and the Door leaf frame 7; Described seal 5 is fixed on door frame 1, the upright doorframe 2.
The utility model solved present mining area slope mouth explosion proof door ubiquity blast back inoperative, because of distortion can not proper reset, explosion proof door easily leaks out, can not cut out automatically, need manually cut out, influence problems such as the normal operation of ventilation system, simple in structure, compact, sealing is reliable, safeguards and check convenience, small investment, esy to use, safe and reliable.
Description of drawings
Fig. 1 is a kind of colliery slope mouth explosion proof door structural front view;
1 door frame, 2 upright doorframes, 3 door leafs, 4 hinges, 6 reversing devices, 7 Door leaf frames, 8 door-plates, 9 reinforcing ribs.
Fig. 2 is a kind of colliery slope mouth explosion proof door structure vertical view;
5 seals, 10 insulation layers.
The specific embodiment
Described door frame 1 is to form with the angle steel assembly welding, is divided into bilateral symmetry two parts, and there is a upright doorframe 2 centre; Described door leaf 3 is formed by Door leaf frame 7, door-plate 8, reinforcing rib 9 assembly weldings, and the inboard of door leaf 3 is provided with insulation layer 10; Be connected with hinge 4 between described door leaf 3 and the upright doorframe 2; Described reversing device 6 is a high strength magnet, is contained on door frame 1 and the Door leaf frame 7; Described seal 5 is fixed on door frame 1, the upright doorframe 2.
When normal the ventilation, door leaf 3 cuts out, and the utility model is barrier wells downstream and surface air fully, prevents distinguished and admirable short circuit, guarantees that ventilation system is normal.When in a single day gas or dust explosion accident take place in the down-hole, reversing device 6 is opened under the gas shock effect of blast, and door leaf 3 is opened, and makes air blast directly be discharged into surface air, play the release effect, prevent that main ventilation fan and ground miscellaneous equipment from damaging; When main ventilation fan is out of service, can open explosion proof door, ventilate to utilize natural ventilation pressure.
