Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The combustion tube 31 is rotatably connected to the combustion chamber 2, and a cavity is left between the two. A heat exchange pipe 6 is arranged inside the cavity. When the burner performs combustion operation, the water inside the water tank 3 is transported to the inside of the heat exchange pipe 6 through the water pump 5 and the delivery pipe 4, so that the combustion chamber 2 and the combustion tube 31 are quickly cooled down to avoid fuel coking. The heat exchange pipe 6 is a curved pipe with the same temperature at each point. While cooling down quickly, the stability of combustion will not be affected by inconsistent temperatures. The return pipe 7 transfers the heat exchanged water to the heat exchanger 6. The water is transported back to the inside of the water tank 3 so that the water circulates all the time, the cooling effect is enhanced, and the practicality is high. The water temperature will gradually increase after a long period of heat exchange. The water temperature sensor 8 detects the water temperature. When the water temperature reaches the set value, the control valve 11 is used to open the drain pipe 10 to discharge the hot water to the designated location. The water inlet pipe 9 is connected to the external water flow pipeline. After the hot water inside the water tank 3 is discharged, water is replenished to the inside of the water tank 3 through the water inlet pipe 9, thereby continuously cooling the combustion chamber 2 with water. Not only can the combustion flame be stabilized by water cooling, but the combustion temperature of the flame can also be reduced, thereby reducing the emission of toxic substances such as nitrogen oxides. The use of hot water will not pollute the environment while improving the utilization rate of resources and extending the service life of the device.

[0032] In this embodiment: through the setting of the cover 13, the cover 13 is rotatably connected to the upper surface of the shell 1 through the support rod 12, which is convenient to open and close. When the device is not in use, the cover 13 blocks the top opening of the shell 1 to reduce the entry of dust and extend the service life of the device. When in use, the cover 13 can be opened by the handle 14.

[0033] Specifically, a feed hopper 15 is fixedly connected to the middle of the top wall of the shell 1 , and a material guide plate 16 is fixedly connected to one end of the feed hopper 15 .

[0034] In this embodiment, the feed hopper 15 and the guide plate 16 are arranged to cooperate with each other to avoid the blockage of the transported biomass particles, and at the same time guide the biomass particles to avoid falling into other positions inside the shell 1.

[0035] Specifically, a first motor 17 is fixedly connected to the middle of the inner side surface of the shell 1 , a rotating rod 18 is fixedly connected to the output end of the first motor 17 , and a conveying blade 19 is fixedly connected to the outer surface of the rotating rod 18 .

[0036] In this embodiment: by setting the conveying blade 19, the first motor 17 drives the rotating rod 18 to rotate, so that the biomass particles conveyed into the guide plate 16 can be conveyed to the inside of the combustion tube 31 under the action of the conveying blade 19, and the conveying is continuous to ensure the normal use of the burner. At the same time, the biomass particles can be broken up to avoid the phenomenon of insufficient combustion of clumped biomass particles, thereby improving the combustion efficiency.

[0037] Specifically, a fixing plate 20 is fixedly connected to the bottom of the outer surface of the shell 1 , and a blower 21 is fixedly connected to the inner side surface of the fixing plate 20 .

[0040] In this embodiment: through the setting of the mixing cylinder 23, the bracket 22 supports and fixes the mixing cylinder 23, one end of the air intake pipe 24 is fixed inside the mixing cylinder 23, and the other end can be connected to the oxygen production equipment or the gas equipment. The one-way valve 25 allows the air intake pipe 24 to only intake air in one direction to avoid gas backflow. The external combustion-supporting gas enters the mixing cylinder 23 and can be transported to the interior of the combustion cylinder 31 under the action of the blower 21, which can transform the biomass particles from the original unstable combustion state to stable combustion, or rely only on gas for combustion, which can meet a variety of combustion needs and expand the applicability of the equipment.

[0041] Specifically, one end of the mixing cylinder 23 is fixedly connected to a diffusion cover 26 , and one end of the diffusion cover 26 is fixedly connected to an air duct 27 .

[0042] In this embodiment: through the setting of the diffusion cover 26, the diffusion cover 26 is fixed at one end of the mixing cylinder 23, and its shape gradually expands from left to right, which can increase the wind force. The air duct 27 is fixed at one end of the diffusion cover 26, close to the combustion cylinder 31, and does not contact the combustion cylinder 31. The mixed gas is transported to the interior of the combustion cylinder 31 through the wind holes on the side of the combustion cylinder 31.

[0043] Specifically, the upper surface of the combustion chamber 2 is fixedly connected with a second motor 28 , the output end of the second motor 28 is fixedly connected with a gear 29 , the outer surface of the gear 29 is meshingly connected with a gear ring 30 , and the interior of the gear ring 30 is fixedly connected with a combustion tube 31 .

[0044] In this embodiment: through the setting of the combustion tube 31, the combustion tube 31 is rotatably connected to the inside of the combustion chamber 2, and a ring gear 30 is installed on one side of its outer surface. The ring gear 30 is meshed with the gear 29. The second motor 28 drives the gear 29 to rotate. The gear 29 can make the combustion tube 31 rotate slowly, which can prevent the biomass particles from rising after entering the combustion tube 31. The biomass particle fuel has no accumulation point and burns fully, thereby improving its combustion efficiency. At the same time, the ash content inside the combustion tube 31 is reduced and will not coke or agglomerate.

[0045] Specifically, a supporting wheel 32 is slidably connected to the outer surface of the gear ring 30 , and the supporting wheel 32 is rotatably connected to the housing 1 .

[0046] In this embodiment: through the setting of the supporting wheels 32, four groups of supporting wheels 32 are rotatably connected to the inner side of the shell 1, and are slidably connected to the ring gear 30, so as to lift and support the ring gear 30, so that the ring gear 30 can rotate more smoothly.

[0047] Specifically, a through hole 33 is formed on the outer surface of the combustion tube 31 , and a waste cover 34 is fixedly connected to the inner bottom wall of the combustion chamber 2 .

[0048] In the present embodiment: through the provision of through holes 33, a plurality of through holes 33 are evenly opened on the outer surface of the combustion tube 31 in the form of a horizontal array and a circular array. After the fuel is completely burned, the generated impurities are discharged to the outside through the through holes 33 and the exhaust cover 34, thereby avoiding the phenomenon of impurity accumulation causing blockage inside the combustion tube 31, thereby improving the practicability of the equipment.

[0049] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0050] Working principle and use process of the present invention: When the water-cooled burner is in use, the cover plate 13 is opened by the handle 14, and the biomass particles are transported into the interior of the housing 1 through the feed hopper 15 and the guide plate 16. The first motor 17 drives the rotating rod 18 to rotate, so that the biomass particles are transported to the interior of the combustion tube 31 under the action of the conveying blades 19, and the biomass particles are broken up to avoid the phenomenon of insufficient combustion of the clumped biomass particles. At the same time, the second motor 28 drives the gear 29 to rotate, and the gear 29 causes the combustion tube 31 to rotate slowly to prevent the biomass particles from burning. After the particles enter the combustion tube 31, they rise up. The biomass particle fuel has no accumulation point and burns fully, which improves its combustion efficiency. At the same time, the ash content inside the combustion tube 31 is reduced and will not coke or agglomerate. The blower 21 supplies air to increase the fire. One end of the air intake pipe 24 is fixed inside the mixing tube 23, and the other end can be connected to the oxygen-generating equipment or the gas equipment. The one-way valve 25 allows the air intake pipe 24 to only intake air in one direction. The external combustion-supporting gas enters the mixing tube 23 and is transported to the interior of the combustion tube 31 under the action of the blower 21, which can change the original unstable combustion state of the biomass particles. The state is changed to stable combustion, or only relying on gas for combustion, which can meet various combustion needs. The water in the water tank 3 is transported to the inside of the heat exchange tube 6 through the water pump 5 and the delivery pipe 4, and the combustion chamber 2 and the combustion tube 31 are quickly cooled to avoid fuel coking. The return pipe 7 transports the water after heat exchange back to the inside of the water tank 3, so that the water circulates all the time, and the cooling effect is enhanced. The temperature of water that has been heat exchanged for a long time will gradually increase. The water temperature sensor 8 detects the water temperature. When the water temperature reaches the set value, the control valve 11 is used to open the drain pipe 10 to discharge the hot water. At the designated location, the water inlet pipe 9 is connected to the external water flow pipeline. When the hot water in the water tank 3 is discharged, water is replenished to the inside of the water tank 3 through the water inlet pipe 9, so as to continuously perform water cooling treatment on the combustion chamber 2. Not only can the combustion flame be stabilized by water cooling, but also the combustion temperature of the flame can be reduced, thereby reducing the emission of toxic substances such as nitrogen oxides. The use of hot water will not pollute the environment while improving the utilization rate of resources. After the fuel is completely burned, the impurities generated are discharged to the outside through the through hole 33 and the exhaust cover 34, avoiding the phenomenon of impurity accumulation causing blockage inside the combustion tube 31.
