Description

Technical Field

[0001] The utility model relates to the technical field of fire-blocking devices, in particular to a fire-blocking device in front of a biomass boiler. Background Art

[0002] A fire arrester is a safety device that is mainly used to prevent external flames from entering equipment, pipelines, and containers that are at risk of fire and explosion, and to prevent flames from spreading between equipment and pipelines. It is usually used in production sites in the petroleum, chemical, coal and other industries, as well as in major places where gas is used, such as home kitchens, to ensure the safe use of gas and prevent fires caused by gas leaks.

[0003] When the flame spreads, the existing boiler front flame arrester generally isolates the material from the flame through a fire arrester plate. However, the flame will cause the internal temperature of the flame arrester to continue to rise. When the internal material temperature reaches or exceeds its own auto-ignition point, the material will burn on its own even without an external ignition source, causing the fire to further spread. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a biomass boiler furnace front fire-blocking device, comprising a main body mechanism, the input end of the main body mechanism is fixedly installed with a fire-blocking mechanism;

[0006] The fire-blocking mechanism includes a conveyor, the inner wall of the conveyor is provided with a temperature detector, the input end of the conveyor is fixedly connected to a discharge valve, the input end of the discharge valve is fixedly connected to a feed pipe, the outer wall of the feed pipe is fixedly sleeved with a group of heat sinks, the input end of the feed pipe is fixedly connected to a storage bin, and the outer wall of the conveyor is fixedly sleeved with two fixing rings.

[0008] Preferably, a gear 1 is fixedly mounted on one side of the outer wall of the two sliding blocks, and a rotating brush is fixedly mounted on the opposite side of the two gears 1.

[0009] Preferably, a motor is fixedly mounted on the outer wall of the conveyor, and a rotating shaft is fixedly mounted on the output end of the motor.

[0012] Preferably, the input end of the boiler body is fixedly connected to the output end of the conveyor.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, with the cooperation of the main body mechanism and the fire-blocking mechanism, the nozzle will spray the cooling water inside the water pipe onto the surface of the conveyor, and then the motor will start, driving the rotating brush to rotate on the surface of the conveyor, and evenly apply the cooling water on the surface of the conveyor, so as to quickly reduce the internal temperature of the conveyor, and avoid the heat from being transferred to the inside of the feed pipe and the storage bin, which will cause the internal material to continue to heat up and spontaneously combust, thereby causing unnecessary losses, improving the utilization rate of materials, reducing the probability of spontaneous combustion of materials, and reducing the speed of fire spread, preventing the fire from continuing to expand and causing damage to the device, and posing a threat to the surrounding equipment and the health of the operator.

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a biomass boiler furnace front fire-blocking device, comprising a main body mechanism 1, and a fire-blocking mechanism 2 is fixedly installed at the input end of the main body mechanism 1;

[0026] The fire-blocking mechanism 2 includes a conveyor 201, the inner surface wall of the conveyor 201 is provided with a temperature detector 202, the input end of the conveyor 201 is fixedly connected with a discharge valve 203, the input end of the discharge valve 203 is fixedly connected with a feed pipe 204, the outer surface wall of the feed pipe 204 is fixedly sleeved with a group of heat sinks 205, the input end of the feed pipe 204 is fixedly connected with a storage bin 206, the outer surface wall of the conveyor 201 is fixedly sleeved with two fixing rings 207, and one side of the outer wall of the two fixing rings 207 is provided with a slide groove 2 08, the inner surface walls of the two slide grooves 208 are movably embedded with sliders 209, one side of the outer wall of the two sliders 209 is fixedly installed with a gear 210, the opposite side of the two gears 210 is fixedly installed with a rotating brush 211, the outer surface wall of the conveyor 201 is fixedly installed with a motor 212, the output end of the motor 212 is fixedly installed with a rotating shaft 213, the outer surface wall of the rotating shaft 213 is fixedly sleeved with a gear 214, and the outer surface wall of the gear 214 is meshingly connected with the outer surface wall of one of the two gears 210.

[0027] The effect achieved by the entire embodiment 1 is that after the discharge valve 203 is started, the material inside the storage bin 206 enters the conveyor 201 through the feed pipe 204, and then the conveyor 201 starts to start, and the material enters the boiler body 101. The conveyor 201 can control the conveying speed of the material to achieve the best combustion conditions in the biomass boiler, thereby improving the thermal efficiency of the biomass boiler. When the flame in the boiler enters the conveyor 201, the temperature detector 202 finds that the temperature inside the conveyor 201 is too high, and the discharge valve 203 starts to close to prevent the flame from igniting all the materials, resulting in material waste and causing the fire to expand. After the motor 212 is started, the rotating shaft 21 3 drives the gear 214 to rotate, the gear 214 will make the gear 1 210 rotate together, the gear 1 210 will drive the rotating brush 211 to evenly apply the cooling water on the surface of the conveyor 201, so that the temperature of the conveyor 201 is quickly reduced, which can not only prevent the spontaneous combustion of the material inside the storage bin 206 due to the high temperature, but also speed up the extinguishing speed of the flame inside the conveyor 201 and reduce the damage of the high temperature to the device. The slider 209 and the slide 208 cooperate with each other to avoid the deviation of the movement direction of the rotating brush 211. A group of heat sinks 205 on the surface of the feed pipe 204 can also speed up the heat dissipation speed of the internal material to prevent the material from self-igniting, deteriorating or burning due to excessive temperature.

[0028] Embodiment 2, as Figure 2-Figure 4 As shown, the main structure 1 includes a boiler body 101, a water pipe 102 is fixedly installed on one side of the outer wall of the boiler body 101, the output end of the water pipe 102 is fixedly connected to a group of nozzles 103, and the input end of the boiler body 101 is fixedly connected to the output end of the conveyor 201.

[0029] The effect achieved by the entire embodiment 2 is that when the fire spreads inside the boiler body 101, a group of nozzles 103 start to start and spray cooling water inside the water pipe 102, thereby quickly lowering the temperature of the device and materials and reducing the probability of spontaneous combustion of the materials.

[0030] Working principle: When the operator needs to use the biomass boiler, he only needs to pour the material into the storage bin 206 first, and then he can start the device. At this time, the discharge valve 203 begins to open, and the material inside the storage bin 206 will fall into the feed pipe 204 under the action of gravity, and then enter the conveyor 201. At this time, the conveyor 201 starts to start and continuously conveys the internal material forward, so that the material enters the boiler body 101 stably and evenly. When the fire in the boiler spreads to the conveyor 201, the internal temperature of the conveyor 201 begins to rise continuously. When the temperature detector 202 finds that the internal temperature of the conveyor 201 is abnormal, the discharge valve 203 begins to close to isolate the flame from the internal temperature of the storage bin 206. At this time A group of nozzles 103 will spray the cooling water inside the water pipe 102 onto the surface of the conveyor 201. At the same time, the motor 212 starts to start, driving the rotating shaft 213 to start rotating. When the rotating shaft 213 rotates, it will drive the gear 214 fixed on the outer wall to rotate together. When the gear 214 rotates, the gear 1 210 meshing with it is also driven to start rotating. During the rotation of the gear 1 210, it will drive the rotating brush 211 to rotate on the surface of the conveyor 201, and evenly apply the cooling water on the surface of the conveyor 201, so that the temperature of the conveyor 201 is quickly reduced. At the same time, when the gear 1 210 rotates, it will drive the slider 209 on one side of the outer wall to slide inside the slide groove 208, so as to facilitate the rotation of the gear 1 210 and the rotating brush 211.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
