Embodiment 1

[0032] refer to figure 1 , a smoke blocking fire door, comprising a door panel 1 and a door frame 2, the edge of the door panel 1 is provided with a recessed part 3, and the materials of the door panel 1 and the door frame 2 are fireproof materials.

[0033] Further, refer to figure 2 with image 3 , the inside of the door panel 1 is provided with a low-pressure water tank 11, a pressure channel 15, an upper block 17 and a side block 19, and the port of the pressure channel 15 at the top of the door panel 1 is provided with an upper groove for accommodating the upper block 17 The pressure channel 15 is located at the port on the side of the door panel 1 to provide a side groove for accommodating the side blocking block 19, and the door frame 2 is provided with an n-type sealing groove 21 on the surface opposite to the door panel 1, and the sealing groove 21 is connected to The position and shape of the groove at the outlet end of the pressure channel 15 correspond to each o...

Embodiment 2

[0037] Different from Example 1, in this example, refer to figure 2 , Figure 4 with Figure 5 , the interior of the door frame 2 is provided with an upper filter 26 and a side filter 27, the upper filter 26 is slidably connected with the door frame 2 in the vertical direction, and the side filter 27 is slidably connected with the door frame 2 in the horizontal direction , the inside of the door frame 2 is provided with a driving assembly for driving the upper filter 26 so that the side filter 27 enters the recessed portion 3 . The upper filter screen 26 and the side filter screen 27 can form a filter layer in the recessed part 3 of the door panel 1 to filter the smoke generated in the fire.

[0038] Specifically, refer to figure 2 with Figure 4 The driving assembly includes a top pressing block 22, a rocker 24 and a rotating base 25, the lower end of the top pressing block 22 is located in the sealing groove 21, and a vertical axis is set between the upper end of the top...

Embodiment 3

[0042] refer to figure 2 with Figure 7 , different from Embodiment 2, the upper blocking block 17 in this embodiment is hollowly set, the surface of the upper blocking block 17 is provided with an air bag 172, and the upper blocking block 17 is provided with an inner cavity communicating with the air bag 172 and the upper blocking block 17 The bottom of the upper block 17 is provided with a one-way air intake valve 171 that communicates with the inner cavity of the upper block 17 and the outlet end of the pressure channel 15, and the inlet end of the pressure channel 15 communicates with the low-pressure water tank 11 , the inlet end of the pressurizing channel 15 communicates with the low-pressure water tank 11 . In this preferred solution, the steam formed in the low-pressure water tank 11 can enter the air bag 172 to make the air bag 172 fuller and enhance the sealing effect of the gap between the door panel 1 and the door frame 2 .

Abstract

The invention discloses a smoke-blocking type fire door, which comprises a door panel and a door frame. A recessed part is arranged on the edge of the door panel, and a blocking block is arranged on the edge of the door panel for sealing the gap between the door panel and the door frame. The door frame is equipped with a filter screen for filtering the smoke generated in the fire. A low-pressure water tank is also installed inside the door panel. An air bag is arranged on the surface of the block. The low-pressure water tank communicates with the air bag. The outer and inner steam flow circles have a certain barrier effect on the smoke. The smoke blocking fire door in the present invention can seal and block the smoke in the gap between the door panel and the door frame, and improve the safety of the fire door. The smoke barrier effect has a positive effect on the breathing safety of people at the fire scene.

Description

technical field [0001] The invention relates to the technical field of fire doors, in particular to a smoke blocking fire door. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. Existing fire doors basically use fireproof materials, which have good fireproof function. Once the fireproof door is closed, it can effectively block the fire from spreading. It flows through the gap between the fire door and the door frame, and enters the safety side of the fire door, posing a threat to the safe...
