Explosion-proof doors are divided into inclined air shaft explosion-proof doors and vertical air shaft explosion-proof doors.
The explosion-proof door of the vertical wind shaft is used at the head of the vertical wind shaft. The maximum negative pressure of the applicable fan is and.
The inclined air shaft explosion-proof door is used at the return air inclined shaft wellhead and is suitable for maximum negative pressure pull-out ventilators.
The model number of the vertical wind shaft explosion-proof door is B/the drawing number is B
The mining I-beam is welded with an I-beam in the center of the door frame, which solves the problem of the central joint between the left and right semi-circular arch door frames when assembling them. At the same time, since each I-beam is of the same model and the connection between them is welded, the processing technology is simple, and the flatness of the surface on the door frame that joins the door panel is easy to ensure.
The mine explosion-proof door is used at the wellhead where the fan is located. The purpose is to open the explosion-proof door in time when an explosion occurs in the mine to facilitate the timely escape of explosive gas. After the gas overflows, the door can automatically close. Choose according to the form of the wellhead. Should I use an inclined shaft explosion-proof door or a vertical shaft explosion-proof door?
Installation method of air shaft explosion-proof door:
First organize and measure the width and height of the tunnel entrance to ensure that the entire explosion-proof door (including embedded parts) is placed.
Place the two doors flat on the ground, arrange the sealing rubber plates between the two doors, and fix the two doors with bolts, ready for installation.
Correct the direction to ensure that the explosion-proof door can only open outward, and then stand the two doors at the wellhead at the same time.
After adjustment, use wooden supports to fix the overall door.
Start building walls and fixing them according to the wellhead design.
After the wall solidifies, close the explosion-proof door, place the blocking rods on the fixed racks on both sides of the door frame, and bury the door centimeters below the outer door with sand, gravel or soil, and it can be used normally.
Our factory can customize according to the actual situation. The explosion-proof doors produced by our factory are of high quality and the prices are favorable. Welcome to buy them.
