Abstract
The utility model discloses an explosion vent with automatic opening device, the pre -buried base of characterized by is fixed in the relevant position, 45 the base is fixed on pre -buried base, the door frame is fixed on 45 bases, the safety cover is fixed on 45 bases, the state monitor is installed in door frame back bottom, adopt the pivot seat to connect between door plant and the door frame, be equipped with the sealing rubber circle between door plant and door frame, the junction of door frame is equipped with <= 90 stopper, guarantee explosion vent automatic re -setting under self action of gravity. The utility model discloses explosion vent processing simple to operate has realized the explosion vent and has opened automatically that explosion vent state automatic monitoring, explosion vent rotary mechanism can not lead to the explosion vent to open the inefficacy because of rustting, and overall structure is simple for this explosion vent, and the reliability is high.
Description
Technical field
This utility model relates to the explosion proof door in power plant, coal works above storage silo.
Background technology
Explosion proof door is mainly used in above the storage silo in power plant, coal works and some coal chemical industry enterprises fabrication line process, and it is that one realizes self-relieving protection device for silo internal pressure is too high.When pressure exceedes design load in silo, it is susceptible to serious explosion accident.We arrange gravity type pressure-relief explosion-proof door in systems, and when in silo, pressure reaches setting value, pressure-relief explosion-proof door automatically opens up, and make pressure in silo guarantee safety within dropping to safety value.Pressure-relief explosion-proof door is provided with status monitoring sensor, it is possible to monitoring pressure port on off state.
Summary of the invention
The purpose of this utility model is to provide a kind of explosion proof door with automatic open device, and it is simple that this explosion proof door has overall structure, reliability high.
The technical solution of the utility model is: a kind of explosion proof door with automatic open device; it is characterized in that pre-buried pedestal is fixed on relevant position; 45 ° of pedestals are fixed on pre-buried impact faces; doorframe is fixed on 45 ° of impact faces; protective cover is fixed on 45 ° of impact faces; state monitor is arranged on doorframe back bottom; pivot pin seat is used to connect between door-plate and doorframe; sealing rubber ring it is provided with between door-plate and doorframe; the junction of doorframe is provided with≤limited block of 90 °, it is ensured that and explosion proof door automatically resets under self gravitation effect.
This utility model explosion proof door is convenient to process and mount, achieve explosion proof door to automatically turn on, while explosion proof door state is monitored automatically, solve explosion proof door in life-time service process reliability problem, rotating mechanism uses stainless steel material can ensure in life-time service process, explosion proof door rotating mechanism does not cause explosion proof door opening failure because getting rusty, and it is simple that this explosion proof door has overall structure, reliability high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1; this explosion proof door is mainly by pre-buried pedestal 1; 45 ° of pedestals 2; state monitor 3; doorframe 4; door-plate 5; protective cover 6, sealing rubber ring 7, pivot pin seat 8; limited block 9 forms; wherein, pre-buried pedestal 1 is fixed on relevant position with concrete cast before the mounting, 45 ° of pedestals 2 pass through welding in installation process or be bolted to above pre-buried pedestal 1; then doorframe 4 is fixed on above 45 ° of pedestals 2 by welding or bolt connecting mode, finally protective cover 6 is fixed on above 45 ° of pedestals 2 by welding or bolt connecting mode.State monitor 3 is arranged on doorframe 4 back bottom, the opening of monitoring door-plate 5；Pivot pin seat 8 is used to connect between door-plate 5 and doorframe 4, pin arrangement 8 is the rotating mechanism that Guan Bi opened by door-plate 5, employing stainless steel material makes, prevent rotating mechanism from getting rusty the inefficacy caused, sealing rubber ring 7 is for the sealing between door-plate 5 and doorframe 4, it is ensured that when in silo, pressure becomes big, door-plate 5 is opened rapidly, limited block 9 is for door-plate 5 rotary stopper, it is ensured that design opening angle and the door-plate 5 of door-plate 5 automatically reset.
This explosion proof door belongs to a kind of gravity type explosion proof door, and it is raised vent panel when being and reach setting according to silo internal gas blast pressure and carrys out the principle design of discharging decompressing.Sealing rubber ring 7 is used to seal between vent panel 5 and doorframe 4, pin arrangement is used to connect between vent panel 5 and doorframe 4, consider outdoor severe operating mode, this pin arrangement uses rush-resisting material design, the junction of doorframe 4 uses≤90 ° spacing, it is ensured that explosion proof door automatically resets under self gravitation effect.When in storehouse, pressure reaches certain value, explosion proof door automatically turns under the effect of pressure in silo；When in storehouse, pressure is reduced to normal pressure, explosion proof door automatically resets under self gravitation effect.
