Description
Technical Field
The utility model relates to a fluidizing device of a blowing tank, which belongs to the technical field of iron-making and coal-injection production equipment in the metallurgical industry.
Background
The injection tank fluidizing chamber is a power source for supplying fuel to a blast furnace in an iron-making coal injection operation area. The gas enters the fluidization chamber to blow away the coal dust in the coal injection tank through the fluidization plate, so that the coal dust is in a suspension state, finally, the coal dust is uniformly and stably conveyed into the blast furnace by pressurizing the tank, and the coal dust provides necessary heat for blast furnace iron making through combustion.
The existing injection tank fluidizing device is in an assembled installation form, the fluidizing plate is fixed to the injection tank by virtue of the flange compression ring, nitrogen directly aligns to the fluidizing plate to pressurize, excessive pressure is caused to the fluidizing plate, after the device is used for a period of time, the fluidizing plate is easy to deform, and the situation that the compression ring fixing screw is broken occurs, so that the fluidizing plate cannot normally work, and a blast furnace distributor and a coal gun are blocked.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a fluidizing device of jetting jar is provided to above-mentioned prior art, can not cause too big pressure to the fluidization board, alleviates the pressure of fluidization board, prolongs the life of fluidization board.
The utility model provides a technical scheme that above-mentioned problem adopted does: a fluidizing device of a blowing tank comprises a fluidizing plate, a collecting barrel with two open ends and an air inlet pipe, wherein the fluidizing plate covers one end of the collecting barrel, and the other end of the collecting barrel covers a first flange; the collecting barrel is characterized in that a sealing cover is arranged at one end of the air inlet pipe, an air inlet is formed at the other end of the air inlet pipe, an air outlet is formed in the peripheral wall of the air inlet pipe, and a first flange is penetrated through one end of the air inlet pipe, so that the air outlet of the air inlet pipe is arranged in the collecting barrel, and the air inlet of the air inlet pipe is exposed out of the collecting.
The gas outlet is equipped with a plurality ofly, and is a plurality of the gas outlet ring is even interval setting.
The end of the collecting barrel is arranged on a concave platform which is matched with a boss on the fluidization plate.
Compared with the prior art, the utility model has the advantages of: the utility model provides a nitrogen gas flows into the intake pipe from the pressurized nitrogen gas pipeline through the air inlet, evenly flows out nitrogen gas and collects in the collecting vessel through a plurality of gas outlets after, has improved the homogeneity of admitting air, and the hole outflow on the nitrogen gas process fluidization plate in the collecting vessel. The nitrogen is buffered in the collecting barrel to a certain degree, so that the pressure of the pressurized nitrogen on the fluidization plate is reduced, and the service life of the fluidization plate is prolonged.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1 and 2, the fluidizing device of the injection tank in the embodiment includes a fluidizing plate 1, a collecting barrel 2 with two open ends, and an air inlet pipe 4, wherein a boss is provided at the bottom of the fluidizing plate 1, a concave table is provided at the top end of the collecting barrel 2, the boss of the fluidizing plate 1 covers the concave table, the fluidizing plate 1 is fixed at one end of the collecting barrel 2 by welding, and the other end of the collecting barrel 2 is fixed with a first flange 3 by welding. One end of the air inlet pipe 4 is provided with a sealing cover 4.3, the other end of the air inlet pipe 4 is provided with an air inlet 4.1, and the circumferential wall of the air inlet pipe 4 is annularly and uniformly provided with 4 air outlets 4.2. First flange 3 is worn to establish by 4 ends of intake pipe with sealed lid 4.3 for in collecting vessel 2 was located to the gas outlet of intake pipe 4, realize that gas outlet 4.2 link up with the inner chamber of collecting vessel 2. The end of an air inlet pipe 4 with an air inlet 4.1 is exposed out of the collecting barrel 2, and the air inlet 4.1 of the air inlet pipe 4 is connected with a pressurizing nitrogen pipeline. The first flange 3 is fixedly connected with a flange at the bottom of the injection tank through a bolt, so that the fluidization device is fixed at the bottom of the injection tank.
Nitrogen flows into the air inlet pipe 4 from the pressurized nitrogen pipeline through the air inlet 4.1, then uniformly flows out through 4 air outlets 4.2 and is collected in the collecting barrel 2, the air inlet uniformity is improved, and the nitrogen in the collecting barrel 2 flows out through holes in the fluidization plate 1. The nitrogen is buffered in the collecting barrel 2 to a certain extent, so that the pressure of the pressurized nitrogen on the fluidization plate 1 is reduced, and the service life of the fluidization plate 1 is prolonged.
