Abstract
The utility model relates to an explosion-proof door device of a mine ventilation system, in particular to a rotary explosion-proof door, which solves the problems that the explosion-proof door of the existing mine ventilation system has poor capability of withstanding shock waves and cannot be operated easily. The rotary explosion-proof door comprises a rotary door body and a door frame, and a rotating shaft penetrates through the rotary door body; the axial line of the rotating shaft is deviated from the middle axial line of the rotary door body; the lower surface of the left side of the door frame is fixedly provided with a left sealing pad, and the left sealing pad is arranged above the rotary door body; the upper surface of the right side of the door frame is fixedly provided with a right sealing pad, and the right sealing pad is arranged below the rotary door body; and the right side of the door frame is hinged with a rotating press plate, and the right end of the rotary door body is arranged between the rotating press plate and the right sealing pad. The rotary explosion-proof door effectively solves the problems that the explosion-proof door of the existing mine ventilation system has poor capability of withstanding shock waves and cannot be operated easily, and is suitable for explosion protection of the mine ventilation system.
Description
Technical field
The utility model relates to the mine ventilation system explosion vent apparatus, specifically is a kind of rotary explosion proof door.
Background technology
At present, the explosion vent apparatus of mine ventilation system generally adopts the overall structure explosion proof door, and it mainly is made up of explosion proof door, balance weight, pressing device, sealing device etc.; Its operating principle is: when gas or coal seam explosion accident take place in the mine down-hole, the shock wave that blast is produced is washed explosion proof door open (balance weight helps out), shock wave with damaging effect is discharged by the explosion proof door place, prevent that ventilation fan from being impacted; Existing mine ventilation system explosion proof door is owing to adopt overall structure, the ability of its ripple that withstands shocks is relatively poor, promptly when bigger shock wave appears in the down-hole, meeting causes taking place explosion proof door owing to shock wave can't discharge at short notice and is washed away accident, and explosion proof door is washed away and not only can personnel and equipment be damaged, also can prolong the recovery ventilation time, cause great potential safety hazard; In addition, existing explosion proof door operates comparatively heavy, promptly break down to open explosion proof door and realize natural ventilation the time when ventilation system, often needing 2-4 people to operate balance weight simultaneously could open explosion proof door, so not only waste of manpower also can cause the down-hole natural ventilation in time not recover simultaneously.Based on this, be necessary to invent a kind of safe in utilization and operate light novel mine ventilation system explosion proof door.
Summary of the invention
The utility model provides a kind of rotary explosion proof door in order to solve existing mine ventilation system explosion proof door the withstand shocks ability and the heavy problem of operation of ripple.
The utility model is to adopt following technical scheme to realize: rotary explosion proof door comprises the revolving door body and the doorframe that are penetrated with rotating shaft on it; The axis of the axis runout revolving door body of rotating shaft; Doorframe left side soffit is fixed with left sealing mat, and left sealing mat is positioned at revolving door body top; Doorframe right side upper surface is fixed with right sealing mat, and right sealing mat is positioned at revolving door body below; The doorframe right side is hinged with rotary pressure plate, and revolving door body right-hand member is between rotary pressure plate and right sealing mat; The doorframe left side is provided with the support vertical with rotating shaft, and the support upper end is equipped with pulley, is wound with backguy on the pulley, and backguy one end and revolving door body right-hand member are fixed, and the backguy other end is hung with balance weight.
The course of work is as follows: during normal air feed, rotary pressure plate rotates to open position, because the revolving door body weight of the rotating shaft left and right sides is unequal, and revolving door body auto-closing; The center of gravity non-equilibrium state that the revolving door body utilizes rotating shaft to depart from and causes is closed naturally; When carrying out inverted ventilation operation (being that the down-hole is for malleation wind), rotary pressure plate is rotated to fastening position, wash the revolving door body open to prevent malleation wind; When accident such as is blasted in the down-hole, because the revolving door bulk area of the rotating shaft left and right sides is unequal, be positioned at the suffered impact force of the revolving door body on rotating shaft right side greater than the suffered impact force of revolving door body that is positioned at the rotating shaft left side, the impact generated by explosion ripple is outwarded winding the revolving door body counterclockwise, when preventing that ventilation fan from being impacted, guaranteed that the revolving door body can not washed away because of being impacted; When ventilation system breaks down need open the revolving door body and realize natural ventilation the time, then only need a people that balance weight is pulled down, the revolving door body is opened, thereby realized natural ventilation; Compare with existing mine ventilation system explosion proof door, rotary explosion proof door described in the utility model adopts rotary structure, and utilize rotating shaft to depart from generation gravity unbalance and impact force and principles such as lifting surface area is directly proportional, explosion proof door has been realized when being subjected to shock wave, can pressure be discharged in moment, thereby prevent that explosion proof door from being washed away the generation of accident, also reached the purpose that explosion proof door easily resets simultaneously, guaranteeing role has been played in prevention ventilation accident expansion and shortening ventilation accident recovery time; Simultaneously, rotary explosion proof door operation described in the utility model is light, has both saved manpower, has guaranteed that also the down-hole natural ventilation can in time recover.
The utility model is simple in structure, reasonable in design, efficiently solves existing mine ventilation system explosion proof door the withstand shocks ability and the heavy problem of operation of ripple, is applicable to that mine ventilation system is explosion-proof.
