[0003] The inorganic fireproof rolling shutter door in the prior art is generally an integrated structure, which can isolate flames, high temperature, thick smoke, etc. when a fire occurs. Since the fire needs to be isolated as soon as possible, people may not be evacuated completely or the best isolation time may be missed due to the need to evacuate the crowd, causing the fire to spread. Therefore, there is a need for a fireproof rolling shutter door that can isolate the fire as soon as possible and still provide space for people to evacuate. Utility Model Content

[0012] A further improvement of the technical solution of the utility model is that the flame retardant particles are one of halogen flame retardant particles, phosphorus flame retardant particles and nitrogen flame retardant particles.
[0013] The above technical solution is adopted, in which the fire-resistant layer, closed wire mesh, flame-retardant particles and central reinforcement layer are used in combination to improve the overall flame-retardant effect of the fireproof rolling shutter door, so that the rolling shutter door will not be easily burned through, effectively preventing the fire from spreading and ensuring safety during use.

[0026] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] The present invention is further described in detail below in conjunction with the embodiments:
[0028] Example 1
[0029] like Figure 1-5 As shown, the utility model provides an inorganic special grade fireproof rolling shutter door, including a fireproof rolling shutter door 1, the fireproof rolling shutter door 1 includes a flame retardant partition layer 8, and the bottom surface of the flame retardant partition layer 8 is fixedly connected with a first separation door 3 and a second separation door 4 through a supporting cross frame 2.
[0030] One side of the second separation door 4 is fixedly connected with a barrier layer 7, and the inner wall of the barrier layer 7 is fixedly connected with a magnetic strip 6 for magnetically adsorbing the first separation door 3. When people pass through the fire shutter door 1 during evacuation, they can directly and easily apply force to open and separate the first separation door 3 and the second separation door 4. After the transfer of people, the first separation door 3 and the second separation door 4 are reattached under the magnetic adsorption of the magnetic strip 6 to block the smoke. The coordination of various structures facilitates the evacuation and withdrawal of people after the fire shutter door 1 is closed. At the same time, when receiving an alarm signal, it can also directly descend to a position that is in contact with the ground to prevent the driving device of the fire shutter door 1 from being affected by the fire and causing failure, and the fire shutter door 1 cannot be closed.
[0031] The fire shutter door 1 can also directly descend to a position in contact with the ground when receiving an alarm signal, to prevent the driving device of the fire shutter door 1 from malfunctioning due to subsequent fire damage, and thus preventing the fire shutter door 1 from being unable to be closed.
[0032] The flame retardant partition layer 8 includes a central reinforcement layer 12 fixedly connected to the bottom of the supporting cross frame 2, flame retardant particles 10 filled on both sides of the central reinforcement layer 12, a closed wire mesh 11 for limiting the position and sealing the flame retardant particles 10, and a fire-resistant layer 9 adhered to the outer wall of the closed wire mesh 11. The bottom surface of the first separation door 3 is fixedly connected to the separation cross frame 5.
[0033] Example 2
[0034] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the first separation door 3 and the second separation door 4 have the same structure, and the two are adsorbed and attached by the magnetic attraction of the magnetic strip 6.
[0035] The flame retardant particles 10 are one of halogen flame retardant particles, phosphorus flame retardant particles and nitrogen flame retardant particles. When the fire area spreads to the side of the fireproof rolling shutter door 1, the fireproof layer 9 is used to block the heat and flame. When the fireproof layer 9 is broken, the flame retardant particles 10 filled in the closed wire mesh 11 will block the flame and improve the flame retardant effect. The upper and lower sides of the flame retardant partition layer 8 are fixedly connected to the support cross frame 2.
[0036] The barrier layer 7 is the outer wall of the magnetic strip 6, and the fire-resistant layer 9 is made of inorganic fiber. The fire-resistant layer 9, the closed wire mesh 11, the flame-retardant particles 10 and the central reinforcement layer 12 are used together to improve the overall flame-retardant effect of the fireproof rolling shutter door 1, so that the rolling shutter door will not be easily burned through, effectively preventing the fire from spreading, and ensuring safety during use.
[0037] The following is a detailed description of the working principle of the inorganic special grade fireproof rolling shutter door.
[0038] like Figure 1-5 As shown, when in use, when a fire occurs inside or outside the fire shutter door 1, the staff will open the fire shutter door 1 through the controller to block the inside and outside of the house. When the fire shutter door 1 descends to a suitable distance from the ground, it stops descending. When people pass by the fire shutter door 1 during evacuation, they can directly and easily apply force to open and separate the first separation door 3 and the second separation door 4. After the transfer of people, the first separation door 3 and the second separation door 4 are re-attached under the magnetic attraction of the magnetic strip 6 to block the smoke.
[0039] The fire shutter door 1 can also directly descend to a position in contact with the ground when receiving an alarm signal, to prevent the driving device of the fire shutter door 1 from malfunctioning due to subsequent fire damage, and thus preventing the fire shutter door 1 from being unable to be closed.
[0040] When the fire area spreads to the side of the fireproof rolling shutter door 1, the fire-resistant layer 9 is used to block the heat and flame. When the fire-resistant layer 9 is broken, the flame-retardant particles 10 filled in the closed wire mesh 11 will block the flame, thereby improving the flame retardant effect.
[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or equipment. In the absence of more restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or equipment including the elements. The above generally describes the utility model in detail, but on the basis of the utility model, some modifications or improvements can be made to it, which is obvious to the general technicians in the technical field. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
