Description

Technical Field

[0001] The present application relates to the technical field of wood-fired stoves, and in particular to a blast-type gasification wood-fired stove. Background Art

[0002] A wood-gas stove is a stove that is widely used in outdoor occasions. It is safer than oil stoves and alcohol stoves. Compared with traditional wood stoves, although both use firewood as fuel, wood-gas stoves have the characteristics of saving fuel, high combustion efficiency, high flame temperature, and little or no smoke.

[0003] Most of the existing gasification wood stoves have only ventilation holes at the bottom to allow air to accelerate the combustion of firewood. This combustion-supporting method makes it difficult to increase oxygen and assist combustion in specific areas of the firewood that are not fully burned in the inner tank. The combustion process is not stable enough, which may easily lead to problems such as uneven flames, temperature fluctuations, and uneven heat distribution in the stove, affecting the overall performance and thermal efficiency of the stove.

[0006] Preferably, the outer surface of the jet tube is provided with an asbestos fiber ring, and the asbestos fiber ring is arranged between the jet tube and the outer shell of the furnace. Asbestos fiber is a material with excellent high temperature resistance. It can withstand high temperatures up to 1000°C and has excellent softness and wear resistance.

[0007] Preferably, the oxygen supply mechanism includes a blower fixedly mounted on a fixed platform, the output end of the blower is fixedly connected to a bellows, the top of the bellows is fixedly connected to a jet tube, and the oxygen supply mechanism can use the jet tube to increase oxygen and assist combustion in three circles of oxygen inlet holes opened on the surface of the inner tank.

[0008] Preferably, the positioning mechanism comprises a motor mounted on a fixed frame, the output end of the motor is fixedly connected to a lower turntable, and the angle of the jet cylinder can be adjusted by the positioning mechanism so as to spray airflow to different oxygen inlet holes.

[0009] Preferably, the outer surface of the lower turntable is fixedly connected to a lower shaft, and the outer surface of the lower shaft is rotatably connected to a swing bar.

[0013] 2. The hot oxygen channel between the inner tank and the outer tank of the blast-type gasification wood-fired stove can effectively reduce the loss of hot oxygen, making the gasification combustion smokeless. In addition, due to the design of increasing oxygen and assisting combustion, the combustion process in the furnace is more stable, reducing problems such as uneven flames and temperature fluctuations, ensuring uniform heat distribution in the furnace and providing a stable and reliable heat source.

[0022] Through the above technical solution, during use of the device, firewood burns in the inner tank 3, and airflow can enter between the outer tank 1 and the inner tank 3 through the air hole 2, and the firewood can be oxygenated and combustion-supported through the upper, middle and lower three groups of oxygen inlet holes. During this process, the positioning mechanism can be used in conjunction with the oxygen supply mechanism to accurately increase oxygen for different oxygen inlet holes, thereby further improving the combustion-supporting effect.

[0023] Specifically, an asbestos fiber ring 11 is provided on the outer surface of the gas jet tube 10 , and the asbestos fiber ring 11 is arranged between the gas jet tube 10 and the furnace outer container 1 .

[0024] Through the above technical solution, the asbestos fiber ring 11 can keep the air jet 10 in a relatively stable state during the process of adjusting the angle, and the asbestos fiber ring 11 can effectively reduce the loss of furnace temperature.

[0025] Specifically, the oxygen supply mechanism includes a blower 12 fixedly mounted on the fixed platform 7 , an output end of the blower 12 is fixedly connected to a bellows 13 , and a top end of the bellows 13 is fixedly connected to the air jet cylinder 10 .

[0026] Through the above technical solution, the bellows 13 has excellent deformation ability, so that during the angle adjustment process of the air jet tube 10, the bellows 13 can always transmit the airflow delivered by the blower 12 to the air jet tube 10.

[0027] Specifically, the positioning mechanism includes a motor 14 mounted on the fixing frame 8 , and an output end of the motor 14 is fixedly connected to a lower turntable 15 .

[0028] Through the above technical solution, when the motor 14 is turned on to drive the lower turntable 15 to rotate, the lower shaft 16 will rotate synchronously therewith.

[0029] Specifically, the outer surface of the lower turntable 15 is fixedly connected to the lower shaft 16 , and the outer surface of the lower shaft 16 is rotatably connected to the swing bar 17 .

[0030] Through the above technical solution, during the deflection process, the bottom end of the pendulum bar 17 will rotate along the lower axis 16, and the top end will rotate along the upper axis 19.

[0031] Specifically, an upper turntable 18 is fixedly sleeved on the outer surface of the rotating shaft 9 , an upper shaft 19 is fixedly connected to the outer surface of the upper turntable 18 , and an outer surface of the upper shaft 19 is rotatably connected to the top of the swing bar 17 .

[0033] Working principle: During the use of the blast-type gasification wood-burning stove, the firewood in the inner tank 3 must be ignited first, and the external airflow can enter between the outer tank 1 and the inner tank 3 through the air hole 2, and enter the inner tank 3 from different positions through the first oxygen inlet hole 4, the second oxygen inlet hole 5 and the third oxygen inlet hole 6, so as to increase oxygen and assist combustion of the firewood in the inner tank 3. The hot oxygen between the inner tank 3 and the outer tank 1 continuously enters the furnace through the three groups of oxygen inlet holes, and the carbon, hydrogen and other gases in the wood react to produce combustible gases, such as CO, H2, etc., which is what we often call wood gas for combustion. The hotter the hot oxygen that enters, the more complete the combustion, so there is very little smoke. At the same time, in order to reduce the loss of hot oxygen, aluminum silicate insulation is made on the outer tank 1 to make the gasification combustion smokeless. The effect is better. When the firewood in some areas of the inner tank 3 is not fully burned, the motor 14 can be turned on to drive the lower turntable 15 to rotate, and the pendulum bar 17 is driven to deflect through the lower shaft 16, and then the pendulum bar 17 drives the upper turntable 18 through the upper shaft 19, so that the upper turntable 18 rotates to a certain extent, which can drive the rotating shaft 9 to rotate synchronously, thereby adjusting the airflow injection angle of the jet cylinder 10, and cooperating with the blower 12 to input the airflow into the jet cylinder 10 through the bellows 13, the jet cylinder 10 can inject the airflow to the corresponding oxygen inlet hole (the oxygen inlet hole here should be closest to the place where the firewood is not fully burned), so as to achieve accurate oxygen enrichment and combustion-aiding in the firewood area where combustion is not complete, and improve the overall performance and thermal efficiency of the furnace body.

[0034] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
