Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the accompanying drawings of the present invention will be combined to clearly and completely describe the technical solutions in the embodiments of the present invention.
In the embodiment shown in fig. 1, the powder supply device of the pulverized coal hot blast stove comprises a lower hopper 1, a nitrogen fluidization pipe 3 is arranged on the outer side surface of the lower hopper 1, a rapping device 2 is arranged on the outer wall of the lower hopper 1, a powder feeder 4 is connected to the lower portion of the lower hopper 1, a powder feeder pipeline 5 is connected to the lower portion of the powder feeder 4, a conveying pipeline 8 is connected to the tail end of the powder feeder pipeline 5, an air blower 6 is arranged on one side of the conveying pipeline 8, a hot blast stove 9 is arranged on the other side of the conveying pipeline 8, a support seat 7 is arranged on the lower portion of the air blower 6, the powder feeder pipeline 5 comprises a first pipeline 501, a second pipeline 502 is arranged at the tail end of the first pipeline 501, a third pipeline 503 is arranged at the tail end of the second pipeline 502, a fan-shaped pipeline 504 is arranged at the tail end of the third pipeline 503, and the tail end of the fan-shaped pipeline 4 is fixedly connected with the conveying pipeline 8, the opening of the fan-shaped duct 504 is directed to the end away from the blower 6.
The first pipeline 501 and the third pipeline 503 are both cylindrical, and the diameter of the third pipeline 503 is smaller than that of the first pipeline 501;
the second pipeline 502 is conical;
the vibrator 2 is an explosion-proof vibrator;
the blower 6 is a variable frequency blower.
When the device is used, the upper end of a blanking hopper 1 is connected with a coal powder bin, when powder is required to be supplied, coal powder enters a powder feeder 4 through the blanking hopper 1, and a vibrator 2 arranged on the outer wall of the blanking hopper 1 can effectively reduce the blockage of the coal powder, so that the coal powder can uniformly and stably enter an air powder pipeline 5 through the powder feeder 4; the pulverized coal entering the air-powder pipeline 5 passes through a first pipeline 501, a second pipeline 502 and a third pipeline 503 to reach a fan-shaped pipeline 504, and the fan-shaped pipeline 504 is connected with the conveying pipeline 8, so that the pulverized coal enters the hot blast stove 9 through the conveying pipeline 8 to be combusted; the blower 6 can provide power for the pulverized coal and send the pulverized coal into the hot blast stove 9; because the air-blower 9 sets up in one side of pipeline 8, it can make the reverse blow of buggy return air duct 5 to be inevitable when consequently blowing to the certain extent has hindered the buggy and has got into hot-blast furnace 9 smoothly, consequently sets up fan-shaped pipeline 504 with the end of buggy pipeline 5, and fan-shaped pipeline 504's opening direction is for the one end of keeping away from air-blower 6, thereby can the reverse buggy volume that passes through buggy pipeline 5 of effectual reduction, make the buggy can be more concentrated supply with hot-blast furnace 9. Through the design, the uniform supply of the pulverized coal can be met, and the combustion is more stable; meanwhile, the pulverized coal is not easy to block, the potential safety hazard is reduced, the safety performance and the service life of the equipment are improved, and the maintenance cost of the equipment caused by pulverized coal blocking are saved.
