Abstract
The utility model discloses a fluidized bed which is suitable for airflow crushing. The fluidized bed comprises a cylinder. An induced air duct and a grading wheel are connected with the upper part of the cylinder. An ascending passage, thick material collection passages, a material inlet pipe, air inlet pipes and spray nozzles are connected with the lower part of the cylinder. The fluidized bed has three innovations that: 1) two air inlet pipes which are horizontally and linearly arranged and face to each other penetrate through the material inlet pipe, materials which enter quickly and sprayed airflow are mixed, and secondary acceleration is realized; 2) two thick material collection passages are arranged, and thick materials are mixed with airflow which is sprayed by another two spray nozzles and are horizontally and linearly arranged and face to each other; and 3) the air inlets of the spray nozzles are larger than or equal to the air outlets of the spray nozzles.
Description
Technical field
The utility model relates to a kind of material disintegrating apparatus, is the fluid bed during air-flow is pulverized.
Technical background
Existing fluid bed comprises cylindrical shell, cylindrical shell top is connected with induced duct and grading wheel bottom and is connected with air inlet pipe, feed pipe, air current spray nozzle, horn mouth, slotted eye, this fluid bed and in use has following defective: after 1, material enters cylindrical shell, can not all in time obtain bump, prolong the time of staying of material in fluid bed.2, the material of failing to enter next process can not all in time obtain bump, has increased coarse fodder storage in the cylindrical shell.3, the nozzle gas outlet is forced down with having increased power consumption and equipment configuration (being equipped with stream pressure 0.7mpa-0.8mpa) greater than air inlet (2.9 times) height.
Summary of the invention
At the defective of existing fluid bed, the utility model provides a kind of fluid bed, and it comprises cylindrical shell, and cylindrical shell top is connected with induced duct, grading wheel.The cylindrical shell bottom is connected with rising passway, the coarse fodder collection channel, and air inlet pipe, feed pipe, nozzle, this fluid bed have 3 innovations.1, two opposed air inlet pipe of horizontal linear penetrate from feed pipe, allow the material and the air-flow that enter fast mix, and secondary quicken.2, two coarse fodder collection channels are set, allow material and two horizontally-opposed jet-stream winds mix.3, the nozzle air inlet is more than or equal to the gas outlet.Above-mentioned 3 solutions have following advantage: 1, reduce supply gas pressure, minimumly can help reducing power consumption and equipment configuration to 0.1MPa.2, material is sneaked into air-flow, is all in time clashed into pulverizing, improves stroke speed, allows a part of material reach quality requirement in the very first time, reduces the time of staying of material at fluid bed.3, after coarse fodder is collected, all in time sneak into airflow strikes and pulverize, reduce coarse fodder and retain the quickening pulverizing cycle.
Description of drawings
Fig. 1 is this type of this practicality air inlet charging schematic diagram (front view)
Fig. 2 is that the utility model air inlet and coarse fodder are collected schematic diagram (side diagrammatic sketch).
Among the figure: 1, induced duct.2, grading wheel.3, cylindrical shell.4, material feeding tube.5, air inlet pipe.6, nozzle.7, coarse fodder collection channel.8, rising passway.9, coarse fodder feed pipe.
The specific embodiment
In Fig. 1 Fig. 2, the top of cylindrical shell 3 is connected with induced duct 1 and grading wheel 2, and the bottom of cylindrical shell 3 is connected with rising passway 8, coarse fodder collection channel 7 material feeding tubes 4, air inlet pipe 5 nozzles 6 coarse fodder feed pipes 9.
Principle explanation: at first produce negative pressure gravitation upwards in the fluid bed, the gas flow at high speed is arranged in the material feeding tube 4, then the high compression air-flow is from nozzle 6 ejections, material is rapidly by material feeding tube 4 afterwards, sneak into the air-flow of two opposed nozzle ejections of horizontal linear, carrying out secondary quickens, bump is pulverized mutually, upwards clash into once more along rising passway 8 at last with the grading wheel 2 that rotates, what reach quality requirement enters next process than granule by grading wheel, and bigger particle falls into coarse fodder collection channel 7, enters coarse fodder feed pipe 9, sneak in the air-flow of in addition two nozzles ejections and clash into pulverizing, finish until work.
Action specification: open induced draught system, adjust grading wheel 2 to the needs rotating speed, in the material feeding tube 4 gas flow is arranged, open air feed, air-flow is from nozzle 6 ejections, open feed, material is sneaked in the air-flow of nozzle 6 ejection by material feeding tube 4 fast and speed is further accelerated, bump is pulverized at the center of nozzle line, upwards clashing into wherein bigger particle once more with grading wheel 2 along rising passway 8 is afterwards knocked away, arrive coarse fodder feed pipe 9 from the coarse fodder collection channel, clash into mutually in the centre, finish until work with other air-flow of two nozzles, 6 ejections.
Claims (1)
- Xxxx. fluid bed that is applicable to that air-flow is pulverized, done innovation from three aspects:1, two opposed air inlet pipe of horizontal linear penetrate from feed pipe, allow the material that enters fast and air-flow mix and secondary quickens,2, two coarse fodder collection channels are set, allow coarse fodder and two opposed jet-stream winds of horizontal linear mix,3, the nozzle air inlet is more than or equal to the gas outlet.
