Description of the embodiments
The utility model will be described in further detail with reference to the drawings and the detailed description.
As shown in fig. 1-6, a rectangular auxiliary air pipe 2 is fixedly arranged on a main air pipe 1, and small air pipes 3 are uniformly arranged on one side of the auxiliary air pipe 2; an adjusting hole is formed in the other side of the auxiliary air pipe 2 corresponding to the small air pipe 3, a fixing nut 4 is welded on the adjusting hole, an adjusting bolt 5 is sleeved into the nut 6 and a sealing gasket 7 and then is inserted into the adjusting hole, one end of the adjusting bolt 5 is a cone, and the diameter of the adjusting bolt 5 is larger than that of the small air pipe 6; the fan 8 is connected with the main air pipe 4.
Firstly, the height of the device mounted on the outer wall 9 of the boiler combustion chamber is determined according to the type of the boiler, and the device is symmetrically mounted on the outer wall 9 of the boiler during mounting, so that the oxygen supply in the combustion chamber can be improved, under the condition of lateral air supply, the air-opposite air flow promotes oxygen supply to go deep, the contact area of the air to combustible materials is increased, and the utilization rate of fuel is effectively improved; a plurality of water-cooling walls 10 are uniformly arranged on the inner side of the outer wall of the boiler, and the intervals of the small air pipes 3 are set according to the intervals of the water-cooling walls 10 in the boiler; drilling holes on the outer wall 9 of the boiler according to the intervals of the small air pipes 3, then inserting the small air pipes 3 of the device through the holes, enabling the small air pipes 3 to pass through between the water cooling walls 10 and only extending out of a small pipe head; the adjusting bolt 5 is screwed into the auxiliary air pipe 2 through the nut 6, the fan 8 is started, and air supply in the furnace is started, when the air supply quantity is required to be adjusted, as one end of the adjusting bolt 5 is a cone and the diameter of the adjusting bolt 5 is larger than that of the small air pipe 3, the air supply quantity of each small air pipe 3 can be properly adjusted through the interval between the cone at the inner end of the adjusting bolt 5 and the outer end of the small air pipe 3, and when certain small air pipes 3 are required to be closed, the air supply quantity of the small air pipes 3 can be closed only by propping the cone at the outer end of the adjusting bolt 5 and the inner end of the small air pipe 3; after the position of the adjusting bolt 5 is adjusted, the adjusting bolt 5 can be fixed through the nut 6 and the sealing gasket 7 on the adjusting bolt 5, and meanwhile, the sealing gasket 7 plays a role in sealing; after the device is installed, the small air pipes 3 pass through the water cooling walls 10, and the cooling effect of the water cooling walls 10 can cool the small air pipes, so that the service life of the small air pipes is prolonged; compared with the air supply device in the prior art, the device only stretches out a small section of tube head in the combustion bin, so that the service life is greatly prolonged; if the device needs to be maintained or replaced, the device can be completed outside the furnace without stopping the furnace and stopping production.
The foregoing is illustrative of the present utility model and is not to be construed as limiting the scope of the utility model. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this utility model, and are intended to be within the scope of this utility model.
