Description
Technical Field
The utility model relates to a coal mine equipment especially relates to a key anti-wind is from compound explosion vent.
Background
The explosion-proof door (cover) is a special sealed well cover installed on the air-exhausting well mouth with main ventilator. During normal ventilation, the air tightness is kept, the underground airflow is isolated from the ground atmosphere, the short circuit of the airflow is prevented, and the normal ventilation system is ensured. When gas or coal dust explosion accidents happen underground, the explosion-proof door (cover) is opened by the blast airflow shock wave, so that the blast airflow is directly discharged to the ground atmosphere, the pressure of the airflow in a mine is reduced, the pressure relief effect is realized, and the main ventilator is prevented from being damaged due to the blast airflow shock. When a fire disaster occurs in an underground air inlet roadway or toxic gas exists in the underground air inlet roadway, in order to prevent flame and the toxic gas from entering a mining area to harm the life of miners, the fire must be extinguished by back wind in time, so that an explosion door (cover) needs to be pressed in time, and the back wind is forcibly implemented underground by adopting a positive pressure mode. The current explosion door (cover) structure adopts a conical structure, a sealing device adopts water sealing, if the explosion door (cover) is subjected to gas explosion, the pressure relief time is long (the process that the explosion door is pushed to the air by vertical explosion gas is a pressure relief process), the explosion door (cover) is easy to be exploded and deformed, the ventilation system can not be recovered at the first time, and poisonous and harmful gas in a mine can be discharged, so that the casualty condition of personnel is aggravated.
In addition, the original explosion door (cover) is inconvenient to install and maintain, eight pressing blocks need to be lifted up and rotated by 90 degrees by manpower during the adverse wind, one end of each pressing block is pressed on the door body, the other end of each pressing block is pressed on a thick plate pre-embedded in the well wall, and the pre-embedded bolts are screwed down. In the case of insufficient personnel preparation or bad weather, the operation of the latch explosion vent takes much time. Because the sealing liquid of the existing explosion-proof door mostly adopts water sealing, water is easy to evaporate, and once the high-low pressure difference of the sealing water is smaller than the ventilation negative pressure, the water is suddenly absorbed, and serious air leakage is formed. The incessant moisturizing can cause water waste, and the ventilation blower driver often sees the condition of sealed water in addition, influences the inspection of patrolling and examining of ventilation blower and the observation of equipment behavior. In winter, in the north, because water is easy to freeze, a non-combustible refrigerating fluid is selected, the outdoor temperature of the northern area can often reach above minus 15 ℃, and the selection and the use of the refrigerating fluid are difficult. The existence of the problems has certain hidden danger to the safety of the coal mine.
