Description

Technical Field

[0001] The utility model relates to the field of fire doors, in particular to a fire door for incinerator feeding equipment. Background Art

[0002] To generate electricity or heat through incineration, fuel pellets made from straw and other biomass waste are used to treat biomass waste. During incineration, a feeding device is required to continuously deliver fuel pellets to the inlet. When the incinerator is operating normally, the flames from the burning fuel pellets remain within the incinerator. However, there is a risk of flames occasionally escaping from the inlet, necessitating protective measures.

[0003] Prior art, utility model patent application number 2019213296473 discloses a double-screw feeding mechanism for a grate furnace, which uses a second pneumatic fire door to protect the feed port from the feeding device. Because fuel particles must pass through the door frame of the fire door, which means there are always fuel particles in the door frame, during the door panel's descent, the fuel particles in the door frame prevent the door panel from fully closing. The flames can also ignite the fuel particles in the door frame and even ignite the fuel particles in the feeding device through the gap, necessitating improvements. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a fireproof door for incinerator feeding equipment, which ensures the closing effect and improves fire safety.

[0005] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a fireproof door for incinerator feeding equipment, including: a door frame, a door panel, a gas tank, a flexible air pipe and a valve, the door panel extends downward from the top of the door frame to the door frame, a cavity is provided in the door panel, a first blowing hole connected to the cavity is provided at intervals at the bottom of the door panel, a pipe joint connected to the cavity is provided at the top of the door panel, a valve is provided on the gas tank, and the flexible air pipe is provided between the valve and the pipe joint.

[0006] In a preferred embodiment of the present invention, a guide groove corresponding to the door panel is provided on the top of the door frame.

[0007] In a preferred embodiment of the present invention, second blowing holes communicating with the cavity are provided at intervals on the upper and lower sides of the door panel facing the door frame.

[0008] In a preferred embodiment of the present invention, the gas tank stores inert gas or perfluorohexanone.

[0009] In a preferred embodiment of the present invention, outwardly extending support plates are respectively provided on both sides of the lower portion of the door frame, connecting plates corresponding to the support plates are provided on both sides of the top of the door panel, and a lifting drive device is provided between the support plates and the upper connecting plates.

[0010] In a preferred embodiment of the present invention, the lifting drive device adopts an air cylinder, an oil cylinder or an electric telescopic rod.

[0011] In a preferred embodiment of the present invention, the gas tank is arranged on a support plate on one side of the door frame.

[0012] The beneficial effects of the present invention are as follows: the present invention points out a fireproof door for incinerator feeding equipment. During the process of the door panel descending and closing, the valve can be opened to introduce the gas in the gas tank into the cavity in the door panel, and the first blowing hole is used to blow downward to the door frame to clean the fuel particles in the door frame, thereby preventing the fuel particles from affecting the descent of the door panel, ensuring the closing effect of the door panel, reducing the gap problem, and having a good fire prevention effect. Inert gas or perfluorohexanone can also be used for fire extinguishing to prevent the fuel particles from burning near the door frame, thereby further improving fire safety.

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1~Figure 2 , the embodiments of the present utility model include:

[0018] like Figure 1The fireproof door for the incinerator feeding equipment shown includes: a door frame 1, a door panel 2, a gas tank 4, a flexible gas pipe 6 and a valve 5. The door panel 2 extends downward from the top of the door frame 1 into the door frame 1. In this embodiment, a guide groove 13 corresponding to the door panel 2 is provided at the top of the door frame 1, and the door panel 2 is guided by the guide groove 13 for lifting and lowering.

[0019] The door frame 1 can be screwed in between the feeding device and the inlet of the incinerator, and the fuel particles enter the inlet of the incinerator through the door frame 1. Outwardly extending support plates 9 are provided on both sides of the lower portion of the door frame 1. Connecting plates 7 corresponding to the support plates 9 are provided on both sides of the top of the door panel 2. A lifting drive device 8 is provided between the support plates 9 and the upper connecting plate 7 to drive the connecting plate 7 and the door panel 2 to rise and fall.

[0020] The support plate 9 can be fixed to the lower part of the door frame 1 by screws, and the connecting plate 7 can be fixed to the top of the door frame 1 by screws, so that the structure is stable. In this embodiment, the lifting drive device 8 adopts a cylinder, a hydraulic cylinder or an electric telescopic rod, and can be controlled by a PLC for lifting and lowering, which is easy to operate.

[0021] A cavity 10 is provided in the door panel 2, a first blowing hole 11 connected to the cavity 10 is provided at intervals at the bottom of the door panel 2, a pipe joint 3 connected to the cavity 10 is provided at the top of the door panel 2, a valve 5 is provided on the gas tank 4, and a flexible air pipe 6 is provided between the valve 5 and the pipe joint 3. The valve 5 can be a solenoid valve controlled by PLC, or a manual valve for manual control.

[0022] In this embodiment, the gas tank 4 stores inert gas or perfluorohexanone, which does not participate in combustion but also has a certain fire extinguishing effect. The gas tank 4 is placed on a support plate on one side of the door frame 1, does not occupy the ground, and has a compact structure.

[0023] In addition, the door panel 2 is provided with second air blowing holes 12 connected to the cavity 10 at intervals on both sides facing the door frame, which can blow air to both sides. During the process of the door panel 2 descending and closing, the valve 5 can be opened to introduce the gas in the gas tank into the cavity 10 in the door panel 2, and the first air blowing hole 11 and the second air blowing hole 12 are used to blow downward to the bottom and two side walls of the door frame 1 to clean the fuel particles in the door frame 1, thereby preventing the fuel particles from affecting the descent of the door panel 2, ensuring the closing effect of the door panel 2, reducing the gap problem between the door panel 2 and the door frame 1, and having a good fire prevention effect. In addition, the escaping inert gas or perfluorohexanone can be used to extinguish the fire, thereby preventing the fuel particles from burning near the door frame 1, further improving the fire safety.

[0024] After the door panel 2 is completely closed, the valve 5 can be closed, or the valve 5 can be kept open depending on the fire situation, so that the inert gas or perfluorohexanone can continue to escape through the tiny gap, extending the fire extinguishing time and further improving fire safety.

[0025] In summary, the utility model provides a fire door for an incinerator feeding device, which does not affect the feeding of the incinerator and can be closed in the event of a fire, thereby improving the fire prevention effect.

[0026] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
