Description

Technical Field

[0001] This utility model relates to the field of steel fire door technology, specifically a steel fire door with a protective structure. Background Technology

[0002] Steel fire doors refer to doors with a specified fire resistance performance, consisting of a steel frame, door leaf skeleton, and door leaf panel. If the door leaf is filled with material, it is filled with fireproof and heat-insulating material that is non-toxic and harmless to the human body, and equipped with fireproof hardware.

[0003] Existing steel fire doors generally offer limited protection. In a fire, the high temperatures cause the steel to lose strength rapidly. Under pressure differences between the inside and outside of the door, its own weight, or external impacts, the door leaf and frame can easily bend, warp, or twist, resulting in a large gap between the fire door and the frame, thus completely losing its airtightness. Therefore, this utility model provides a steel fire door with a protective structure. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a steel fire door with a protective structure, solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a steel fire door with a protective structure, comprising a door panel and a door frame. The back of the door frame is connected to the door panel via a hinge. A steel frame is provided in the middle of the internal interlayer of the door panel. A heat insulation core is laid between the layers of the steel frame inside the door panel. Heat-conducting plates are fixedly installed on both sides of the inner wall of the door panel. Several capillary tubes are installed between two of the heat-conducting plates inside the door panel. A spray pipe is fixedly installed on the top front of the door frame. Several nozzles are installed at the bottom of the spray pipe. A fire box is provided at the bottom back of the door frame. An electromagnetic valve connector is fixedly installed on the inner top wall of the fire box. A fire extinguisher fixedly connected to the electromagnetic valve connector is provided inside the fire box. One end of the electromagnetic valve connector is fixedly connected to the spray pipe via a conduit. A fire alarm sensor is located on the front of the door frame.

[0008] Preferably, handles are installed on both the front and back of the door panel.

[0009] Preferably, the heat insulation core is made of nano-silica aerogel.

[0010] Preferably, the front of the door panel is coated with a high-performance ceramic coating.

[0011] Preferably, the interior of the capillary is filled with a phase change coolant.

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a steel fire door with a protective structure, which has the following beneficial effects:

[0014] This steel fire door with a protective structure is designed with a steel frame, heat insulation core, heat-conducting plate, and capillary tube. In the event of a fire, the high-performance ceramic coating sprayed on the door panel surface effectively resists direct flame impact and reflects most of the heat back. When the door panel temperature rises to a certain level, the coolant inside the capillary tube absorbs heat and undergoes a liquid-gas phase change. The vapor carries a large amount of heat to the condensation zone at the edge of the door panel, while the heat-conducting plate conducts the heat through the door frame to the wall for dissipation. This effectively prevents the fire door from deforming due to high temperatures and improves safety. Through the coordinated design of the sprinkler pipe, nozzle, fire box, solenoid valve connector, fire extinguisher, conduit, and fire alarm sensor, the fire alarm sensor is triggered when a fire occurs. The solenoid valve connector receives an electrical signal and is automatically activated. The liquid in the fire extinguisher is transported through the conduit to the sprinkler pipe and then sprayed out through the nozzle to block the flames, thus improving the fire resistance of the fire door.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3This utility model provides a technical solution: including a door panel 1 and a door frame 2, the back of the door frame 2 is connected to the door panel 1 by a hinge 3, a steel frame 4 is provided in the middle of the internal interlayer of the door panel 1, a heat insulation core 5 is laid between the layers of the steel frame 4 inside the door panel 1, heat conducting plates 6 are fixedly installed on both sides of the inner wall of the door panel 1, several capillary tubes 7 are installed between two heat conducting plates 6 inside the door panel 1, a spray pipe 8 is fixedly installed on the top of the front of the door frame 2, and several nozzles 9 are installed at the bottom of the spray pipe 8. A fire extinguisher box 10 is installed at the bottom of the back of the door frame 2. An electromagnetic valve connector 11 is fixedly installed on the inner top wall of the fire extinguisher box 10. A fire extinguisher 12, fixedly connected to the electromagnetic valve connector 11, is installed inside the fire extinguisher box 10. One end of the electromagnetic valve connector 11 is fixedly connected to the spray pipe 8 via a conduit 13. A fire alarm sensor 14 is located on the front of the door frame 2. Through the coordinated arrangement of the spray pipe 8, nozzle 9, fire extinguisher box 10, electromagnetic valve connector 11, fire extinguisher 12, conduit 13, and fire alarm sensor 14, a fire alarm will activate when a fire occurs. When the fire alarm sensor 14 is triggered, the solenoid valve connector 11 receives an electrical signal and is automatically activated. The liquid in the fire extinguisher 12 is transported to the spray pipe 8 through the conduit 13, and then sprayed out through the nozzle 9 to block the flames, thereby improving the fire resistance of the fire door. Handles 15 are installed on both the front and back of the door panel 1. The heat insulation core 5 is made of nano-silica aerogel. The front of the door panel 1 is coated with a high-performance ceramic coating. The inside of the capillary tube 7 is filled with phase change coolant. With the cooperation of the steel frame 4, heat insulation core 5, heat conduction plate 6 and capillary tube 7, when a fire occurs, the high-performance ceramic coating on the surface of the door panel 1 can effectively resist the direct impact of the flames and reflect most of the heat back. When the temperature of the door panel 1 rises to 150°C, the coolant inside the capillary tube 7 absorbs heat and undergoes a liquid-gas phase change. The vapor carries a large amount of heat and moves to the condensation area at the edge of the door panel. At this time, the heat conduction plate conducts the heat through the door frame to the wall for dissipation, thereby effectively preventing the fire door from deforming due to high temperature and improving safety.

[0021] In summary, this steel fire door with a protective structure, through the coordinated arrangement of a steel frame 4, a heat insulation core 5, a heat-conducting plate 6, and capillary tubes 7, effectively resists direct flame impact and reflects most of the heat back when a fire occurs, thanks to the high-performance ceramic coating sprayed on the surface of the door panel 1. When the temperature of the door panel 1 rises to 150°C, the coolant inside the capillary tubes 7 absorbs heat and undergoes a liquid-gas phase change. The vapor carries a large amount of heat towards the condensation zone at the edge of the door panel, while the heat-conducting plate conducts the heat through the door frame to the wall for dissipation. This effectively prevents the fire door from deforming due to high temperatures and improves its safety. Through the coordinated arrangement of the spray pipe 8, nozzle 9, fire box 10, solenoid valve connector 11, fire extinguisher 12, conduit 13 and fire alarm sensor 14, when a fire occurs, the fire alarm sensor 14 will be triggered. At this time, the solenoid valve connector 11 will receive an electrical signal and be automatically triggered. The liquid in the fire extinguisher 12 will be transported to the spray pipe 8 through the conduit 13, and then sprayed out through the nozzle 9 to block the flames, thereby improving the fire resistance performance of the fire door.
