The beneficial effects of the utility model are, when the boiler furnace superpressure, cover plate is subject to gas and impacts and to open fast, discharge gases at high pressure, sensor circuit is connected automatically simultaneously, and automatically open warning system, after in stove, pressure release completes, the cover plate of explosion proof door relies on to automatically reset and builds, buzzer and LED alarm lamp continue to report to the police, and alert is got rid of potential potential safety hazard.
The accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model device;
Fig. 2 is the plan structure schematic diagram of the utility model device.
In figure, 1. cover plate, 2. rubber asbestos gasket, 3. sealing ring flat-plate, 4. tube connector, 5. refractory concrete layer, 6. connecting rod, 7. cross bar, 8. buzzer, 9.LED alarm lamp, 10. bearing pin, 11. poles, 12. boiler barrels, 13. boiler furnaces, 14. split pins, 15. bearing pin sleeve pipes.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1 and Figure 2, the structure of the utility model device is, comprises the tube connector 4 of vertical installation, and tube connector 4 lower port put in downwards in boiler barrel 12 from the top of boiler furnace 13, and the coated inner wall of tube connector 4 has refractory concrete layer 5; The upper port of tube connector 4 is provided with cover plate 1, and cover plate 1 upper surface is installed with the outer end of 6, two connecting rods 6 of pair of links and stretches out cover plate 1 and be fixedly connected with respectively coaxial bearing pin sleeve pipe 15; Tube connector 4 upper port outers are installed with sealing ring flat-plate 3, and sealing ring flat-plate 3 upper surfaces are provided with rubber asbestos gasket 2, when cover plate 1 is buckled in tube connector 4 upper port, realize both sealings; Be installed with a pair of pole 11 on tube connector 4 epimere outer walls, two pole 11 tops have coaxial pin shaft hole, this is to jointly being installed with a bearing pin 10 in pin shaft hole and two bearing pin sleeve pipes 15, for pair of links 6 and a pair of pole 11 are hinged together, one end of bearing pin 10 is provided with split pin 14, thereby makes cover plate 1 and tube connector 4 become a relatively turnable integral body; Be installed with cross bar 7 at a pair of pole 11 tops, be provided with the contact induction circuit on cross bar 7, the contact induction circuit is connected with warning device (embodiment is buzzer 8 and LED alarm lamp 9) simultaneously.
Overhead gravity type explosion proof door directly is connected with burner hearth and is placed in the boiler top, leans on the deadweight of cover plate to make its normal pass, and when in burner hearth, the thrust of flue gas is greater than the equilibrant force produced because of deadweight, cover plate is pushed open by gas, releases the flue gas that the stove implode produces.Cover plate 1 upwards is opened to certain angle, and pair of links 6 is upwards rotated and just can be touched the position that cross bar 7(presets cross bar 7), the contact induction circuit on cross bar 7 will be connected, and buzzer 8, LED alarm lamp 9 will be reported to the police.
The course of work of the utility model device is, when the fuel gas in boiler furnace 13 is blasted, pressure in boiler furnace 13 is greater than the deadweight of cover plate 1, cover plate 1 will be opened by impact automatically, the gases at high pressure that blast is produced discharge, when cover plate 1 is opened to certain aperture, the contact induction circuit is connected automatically, buzzer warning LED alarm lamp flicker simultaneously, connecting rod 6 is collided with cross bar 7, be less than the deadweight of cover plate 1 after pressure drop in boiler furnace 13, cover plate 1 resets in time, burner hearth is isolated from the outside, after the contact induction circuit is connected automatically, buzzer and LED alarm lamp continue to report to the police, until reaching the spot, operating personnel get rid of potential potential safety hazard.
