Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof doors, in particular to a smoke exhaust type fireproof door. Background Art

[0002] A fire door is a type of door that can isolate the source of fire to a certain extent and for a certain period of time when a fire occurs. Compared to ordinary doors, it has the characteristics of high structural strength and high temperature resistance. Therefore, fire doors are usually required between the interior of a building and the entrance to the passage. In this way, in the event of a fire indoors, it can prevent the fire from spreading to the safe passage, or prevent the fire in the safe passage from spreading to the interior.

[0003] Current fire doors still have certain functional defects during use. Since fire doors cannot guarantee absolute sealing effect when closed, when isolating a fire, although they can directly block the open flame, the smoke will still spread from one side of the door body to the other side through the door gap, so that a large amount of smoke will still appear on the non-fire side of the door body, thereby posing certain dangers to people who are escaping and evacuating.

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the following technical problems in the prior art: the current fire door cannot effectively block the smoke passing through the door gap when isolating the fire source, so that the smoke still diffuses to the other side in large quantities, resulting in low practicality. Therefore, the purpose of the utility model is to provide a smoke exhaust fire door, which aims to collect the smoke passing through the door gap through its own structure and guide it to the outside of the building, so as to effectively remove the smoke and reduce the spread of smoke.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Reference Figure 1-4 An embodiment of the utility model provides a smoke exhaust fire door, comprising a door frame 1 and a door leaf 2 of matching sizes, and also comprising the following parts:

[0032] The fixing pipe 3 constructed on the door leaf 2, as shown in the figure, can be located at the top of the door leaf 2, and the fixing pipe 3 is rotatably matched with the door frame 1, so as to complete the installation of the door leaf 2 on the door frame 1. Here, for the rotational installation, there should be two fixing pipes 3, which are distributed up and down. The one shown in the figure is one, and a cylindrical end 12 is constructed at the bottom of the door leaf 2 for the rotational installation. The end of the fixing pipe 3 extends to cross the door frame 1;

[0033] Air suction holes 4 are arranged along the edge of the door leaf 2, and all the air suction holes 4 are connected to the fixed pipe 3;

[0034] A suction assembly 5 is provided on the door leaf 2, and the suction assembly 5 is used to create a suction effect in the communication area formed between the air suction hole 4 and the fixed pipe 3, so that the gas in the air suction hole 4 can flow to the side of the fixed pipe 3;

[0035] Based on the above, when the utility model is installed, an exhaust passage needs to be configured inside the wall of the building. For example, a pipe for exhaust can be buried in the wall, one end of which needs to lead to the outside of the building, and the other end can be extended to the door frame 1. After the door frame 1 and the door leaf 2 are installed, it is ensured that the end of the fixed pipe 3 extends into the exhaust passage. According to the position relationship of the air intake hole 4, when the door leaf 2 is closed, the air intake hole 4 is just facing the door gap;

[0036] When a fire occurs, if the smoke on the fire side flows to the door gap, the suction hole 4 is used to suck the smoke through the suction component 5, so as to keep the smoke flowing into the fixed pipe 3 and finally flow into the exhaust duct, and then be discharged to the outside of the building; compared with the fire door in the prior art, the utility model can effectively reduce the phenomenon of smoke passing through the door gap to the other side, thereby isolating the smoke and at the same time preventing the smoke on the fire side from being discharged to the outside of the building, so as to reduce the smoke concentration in the room.

[0037] Further, see Figure 4A water storage chamber 6 is also provided in the door leaf 2, and the water storage chamber 6 is used to hold water. The fixed pipe 3 and the air intake hole 4 are both connected to the water storage chamber 6, so as to realize the connection between the fixed pipe 3 and the air intake hole 4 through the water storage chamber 6; through the cooperation of the water storage chamber 6, when the smoke flows to the outside of the building, it will pass through the water body, and some solid particles in the smoke can be effectively filtered, thereby reducing the emission of pollutants into the air, and at the same time, it can also effectively prevent the exhaust passage from being blocked due to excessive pollutants.

[0038] Further, see Figure 4 The door leaf 2 is constructed with a tube cavity 7 distributed along the edge of the door leaf 2, the air intake hole 4 is connected to the tube cavity 7, and an air supply channel 8 is connected between the tube cavity 7 and the water storage chamber 6, so as to realize the connection between the air intake hole 4 and the water storage chamber 6. Based on this, the suction component 5 includes a fan blade 501 rotatably arranged in the air supply channel 8, and a driving motor 502 configured to be transmission-connected to the fan blade 501; when the driving motor 502 is working, the cooperation between the fan blade 501 and the air supply channel 8 realizes the suction effect on the inside of all the air intake holes 4 at the same time, thereby effectively ensuring that the smoke passing through the door gap can be absorbed.

[0039] Further, see Figure 4 The driving motor 502 is arranged in the water storage chamber 6, and the shaft of the fan blade 501 directly penetrates into the water storage chamber 6 to achieve connection with the driving motor 502; by arranging the driving motor 502 in the water storage chamber 6, the temperature of the driving motor 502 can be prevented from being too high by the action of the water body, and at the same time, the wall thickness of the wall of the water storage chamber 6 is directly composed of the door leaf 2, so that the water body can be dissipated through the contact between the surface of the door leaf 2 and the air to ensure that the water temperature does not rise too high, thereby protecting the driving motor 502; regarding the power-on method of the driving motor 502, its circuit can directly follow the water storage chamber 6 and the fixed pipe 3 to the outside.

[0040] Furthermore, in order to enable the drive motor 502 to work in time when smoke occurs or leaks, the utility model can also be provided with a smoke sensor, which can be arranged indoors, on the door frame 1 or the door leaf 2, which is omitted in the figure. The smoke sensor can directly establish a signal connection with the drive motor 502, so that when the smoke sensor detects smoke, the drive motor 502 can immediately enter the working state, thereby further improving the practicality of the utility model.

[0041] Further, see Figure 5The specific number of the fan blades 501 can be set to be multiple and coaxially arranged. Among the multiple fan blades 501, the number of single blade units can be set to increase in sequence, so that when sucking out smoke, the suction force of the smoke can be fully guaranteed, so that the smoke can be fully pressed into the water; in addition, this design can also achieve the crushing effect of large particles of impurities in the smoke to prevent the smoke from being blocked in the subsequent path.

[0042] Further, see Figure 6 A blocking block 9 is arranged at the connection between the gas transmission channel 8 and the water storage chamber 6, and the number of the blocking blocks 9 can be multiple. The blocking blocks 9 are flexible structures and are located at the bottom of the water storage chamber 6. A through-slit 10 is constructed on the blocking blocks 9; so that smoke can only pass through the through-slit 10 when flowing from the gas transmission channel 8 to the water storage chamber 6. Under normal circumstances, the blocking blocks 9 are squeezed by the inner wall of the gas transmission channel 8 so that the through-slit 10 is completely in a closed state, so that the water body will not fall down. When the smoke is squeezed by the fan blades 501, it can be forcibly drilled into the through-slit 10, thereby entering the water storage chamber 6; through this design, when the smoke enters the water storage chamber 6, it can first enter the bottom of the water, and then be discharged to the top of the water body by buoyancy, and finally enter the fixed pipe 3, thereby fully ensuring the time for the smoke to flow through the water, so as to give full play to the filtering effect of the water body on the smoke.

[0043] Further, see Figure 1-4 In order to facilitate the replacement of the water in the water storage chamber 6 after a fire occurs, a drain port 11 connected to the water storage chamber 6 is provided on the door leaf 2, so that the water can be poured in and discharged. The opening and closing of the drain port 11 can be achieved by providing a valve cover thereon.

[0044] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
