Description

Technical Field

[0001] This utility model relates to an explosion-proof door, specifically a pressure-resistant, multi-layer explosion-proof door. Background Technology

[0002] Blast-proof doors are designed to withstand accidental explosions in industrial, chemical, and military fields. They utilize high-strength materials and structures to mitigate the hazards of shock waves, ensuring the safety of personnel and equipment. During an explosion, they withstand preset pressure to reduce casualties and property damage. They can be used normally when the preset pressure is not reached. Even after deformation due to overpressure, they maintain their basic functions to prevent people from being trapped. Blast-proof doors use lightweight special steel plates and a multi-layered composite structure, balancing strength and durability. They also possess fire-retardant, high-temperature resistant, and corrosion-resistant properties, adapting to harsh environments. Their sealing design isolates contamination, and they are equipped with self-closing devices and emergency escape functions, combining everyday practicality with emergency safety. They are widely used in high-risk locations such as petrochemical and military industries.

[0003] In the prior art, patent number 201721179695.X describes an automatic opening and closing explosion-proof door for a furnace body. This utility model belongs to the field of explosion-proof technology. The automatic opening and closing explosion-proof door for a furnace body includes an explosion-proof door shell. The bottom of the explosion-proof door shell has an opening, and an explosion-proof door is installed in the opening. A cylindrical limiting cap is installed on the top of the explosion-proof door shell. The automatic opening and closing explosion-proof door for a furnace body also includes at least two guide columns vertically fixed to both sides of the inner wall of the explosion-proof door shell. The two ends of the guide columns are respectively fixed to the two ends of the explosion-proof door shell. The explosion-proof door is slidably connected to the guide columns. A spring with a limiting rod is installed at the center of the explosion-proof door shell. One end of the spring abuts against the explosion-proof door, and the other end abuts against the limiting cap. The limiting rod passes through the spring, with one end connected to the explosion-proof door and the other end inserted into the limiting cap to limit the compression of the spring. When the pressure inside the furnace reaches the set value, the explosion-proof door can slide upward along the guide column to automatically open and quickly reset, preventing air from entering and avoiding secondary explosions. The explosion-proof door can be reused.

[0004] Existing blast-resistant doors can prevent air from entering and avoid secondary explosions. They can be reused, but they also have insufficient resistance levels and cannot withstand larger explosions. Utility Model Content

[0005] In order to overcome the shortcomings of existing technologies that cannot resist large explosion energies, this utility model provides a pressure-resistant, multi-layer explosion-proof door.

[0006] This utility model adopts the following technical solution: a pressure-resistant, multi-layer explosion-proof door, comprising an explosion-proof door body, the explosion-proof door body being divided into a front explosion-proof door body and a rear explosion-proof door body, with an explosion-proof space between the front and rear explosion-proof door bodies, door frame edges for fixing on the front and rear explosion-proof door bodies, assembly components for further assembly with a wall on the door frame edges, the assembly components for further assembly with the wall being assembly pins, threaded holes on the door frame edges, assembly pins for assembly being installed in the threaded holes, sealing components on the assembly pins, secondary locking components (locking screws) within the explosion-proof space between the front and rear explosion-proof door bodies, and an adapter locking platform between the front and rear explosion-proof door bodies, a round hole on the adapter locking platform, into which the locking screw is inserted, and a driving component on the top of the locking screw.

[0007] The driving component is a drive motor, which is equipped with a drive shaft. An assembly flange is provided on the drive shaft for assembling the locking screw, and the assembly flange and the locking screw are assembled and connected.

[0008] The adapter locking platform between the front blast-resistant door body and the rear blast-resistant door body is divided into a front adapter locking platform and a rear adapter locking platform. The front adapter locking platform is located on one side of the front blast-resistant door body, and the rear adapter locking platform is located on one side of the rear blast-resistant door body.

[0009] The assembly pin is provided with a sealing component, which is a sealing glue box. The sealing glue box is provided with an assembly hole, and the assembly pin is adapted to fit into the assembly hole. The sealing glue box is provided with a slow-release module.

[0010] The slow-release module is a slow-release sponge, and the slow-release sponge is filled with sealant. When the slow-release module is squeezed, the sealant is released.

[0011] The front and rear blast-resistant door bodies are provided with locking parts, which are locking pins. The front and rear blast-resistant door bodies are provided with transverse insertion holes, and locking pins are installed in the transverse insertion holes.

[0012] Compared to existing technologies, the front and rear blast-resistant door bodies, along with the intermediate blast-resistant space, constitute a spatial energy dissipation system. The explosion shock wave deforms sequentially through the outer door body, achieving a gradual attenuation of the explosion-proof energy. Combined with the cross-locking system formed by the locking screw and the transverse pin, the top drive motor of the locking screw is equipped with a torque sensor, which can dynamically adjust the locking force according to the impact intensity. Under the overpressure of the explosion, the drive motor forcibly tightens the locking screw, making the door body and the locking platform form a rigid constraint.

[0013] The assembly pin integrates a sealing box and a slow-release sponge module. During assembly, the slow-release sponge releases the injected flame-retardant sealant under pressure, filling the dynamic gap between the door frame and the wall in real time. Combined with the pre-tightening force of the threaded hole, a suitable composite seal is formed, ensuring that the door maintains structural integrity and sealing even when deformed under pressure. The front and rear blast-resistant door bodies are equipped with transverse insertion holes, and locking pins are installed in the transverse insertion holes to lock the blast-resistant door effectively.

The door frame 4 is provided with... A threaded hole is provided, and an assembly pin 5 for assembly is provided in the threaded hole. A sealing component is provided on the assembly pin 5. A secondary locking component is provided in the explosion-proof space between the front explosion-proof door body 1 and the rear explosion-proof door body 2. The secondary locking component is a locking screw 6. An adapter locking platform 7 is provided between the front explosion-proof door body 1 and the rear explosion-proof door body 2. A round hole is provided on the adapter locking platform 7. The locking screw 6 is inserted into the round hole. A driving component is provided on the top of the locking screw 6.

[0022] The driving component is a drive motor 8, which has a drive shaft 9. An assembly flange 10 is mounted on the drive shaft 9, which is used to assemble the locking screw 6. The assembly flange 10 and the locking screw 6 are connected. An adapter locking platform is provided between the front blast-resistant door body 1 and the rear blast-resistant door body 2, consisting of a front adapter locking platform and a rear adapter locking platform. The front adapter locking platform is located on one side of the front blast-resistant door body, and the rear adapter locking platform is located on one side of the rear blast-resistant door body. During installation, the drive motor needs to be installed on the upper part of the door frame 4, with a separate surface cast to provide an assembly position for the drive motor 8. During assembly, only the front blast-resistant door body 1 is installed at the door opening, and the rear blast-resistant door body 2 is installed behind it. Alternatively, supports can be built on both sides of the rear blast-resistant door body 2 to provide the installation position for the drive motor.

[0023] The front blast-resistant door body 1, the rear blast-resistant door body 2, and the intermediate blast-resistant space constitute a certain space energy dissipation system. The explosion shock wave deforms through the outer door body in sequence, achieving energy attenuation at each level. Combined with the "cross locking" system formed by the locking screw and the transverse pin, the top drive motor 8 of the locking screw 6 is equipped with a torque sensor, which can dynamically adjust the locking force according to the impact intensity. Under the explosion overpressure, the drive motor forcibly tightens the locking screw, so that the door body and the locking platform form a rigid constraint.

[0024] The assembly pin 6 is equipped with a sealing component, namely a sealing glue box 11. The sealing glue box 11 is provided with an assembly hole, and the assembly pin 6 is adapted to fit into the assembly hole. The sealing glue box 11 is provided with a slow-release module, which is a slow-release sponge 12. The slow-release sponge 12 is filled with sealant. The sealing glue box 11 is provided with a round hole. When the slow-release module is squeezed, the sealant is released, and the sealant seeps out into the round hole. The front blast-resistant door body 1 and the rear blast-resistant door body 2 are provided with locking parts, which are locking pins 13. The front blast-resistant door body 1 and the rear blast-resistant door body 2 are provided with transverse insertion holes, and the locking pins 13 are installed in the transverse insertion holes.

[0025] The assembly pin 5 integrates a sealing box and a slow-release sponge 12. During assembly, the slow-release sponge 12 releases the injected flame-retardant sealant under pressure, filling the dynamic gap between the door frame and the wall in real time. Combined with the pre-tightening force of the threaded hole, a suitable composite seal is formed, ensuring that the door maintains structural integrity and sealing even when it is deformed under pressure. The front explosion-proof door body 1 and the rear explosion-proof door body 2 are provided with transverse insertion holes. The locking pin 13 installed in the transverse insertion holes can effectively lock the explosion-proof door.
