The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further details.
As shown in Figure 1, this preferred embodiment comprises powder storehouse body 1, interior fluidizer 2, inlet point 14 and discharging opening 8, and inlet point 14, discharging opening 8 are located at the above and below of powder storehouse body 1 respectively, and in order to control the discharging process, this preferred embodiment also comprises unloader 7.
For fluidizer 2 in making can prevent that powder 9 from putting up a bridge, the advantage maximization of perforation, in this preferred embodiment, interior fluidizer 2 is located at below in the in-to-in of powder storehouse body 1, and the tip of fluidizer 2 is provided with up in bevelled.In this preferred embodiment, interior fluidizer is 1, if the volume of powder storehouse body is very big, when an interior fluidizer can not satisfy the demands, then can powder storehouse body interior be provided with a plurality of in fluidizer, preferred embodiment as shown in Figure 5 is though two interior fluidizers 2 in the powder shown in Figure 5 storehouse body 1 are horizontally set, but be not limited thereto, can in the body of powder storehouse, be provided with a plurality of vertically and/or the interior fluidizer of horizontally set.
More smooth and easy and increase fluidisation disturbance to powder 9 for the discharge that makes powder 9, the bottom of the powder storehouse body 1 of this preferred embodiment is funnel-form, and the bottom of powder storehouse body 1 also is provided with the outer air-distribution device 11 that is communicated with external air inlet pipe 10.In other embodiments, stronger if the diameter of powder storehouse body is not the blowability of enough big or interior air-distribution device 11, then can omit outer air-distribution device.
The top of powder storehouse body 1 is provided with exhausr port 14, so that discharge powder storehouse body 1 from the high pressure gas of outer air- distribution device 11 and 4 outflows of interior air-distribution device.
As shown in Figure 2, when using preferred embodiment shown in Figure 1, the outer high pressure gas 12 that come from external admission pipe 10 enter in the powder storehouse body 1 by outer air-distribution device 11, the powder 9 that enters powder storehouse body 1 from inlet point 14 moves from the top down, powder 9 is divided into central area blanking 16 and adherent regional blanking 17 in moving downward process.During the conical suface 13 of central area blanking 16 fluidizer 2 in coming downwards to (also can be referred to as lozenges) zone, run into and pass the inner high voltage gas 3 that interior air-distribution device 4 enters powder storehouse body 1, form the relatively low interior fluidisation powder 18 of density.Adherent regional blanking 17 is air-distribution device 11 places outside coming downwards to, and run into to pass the outer high pressure gas 12 that outer air-distribution device 11 enters powder storehouse body 1, form the relatively low outer fluidisation powder 19 of density.Finally, interior fluidisation powder 18 and outer fluidisation powder 19 converge at discharging opening 8 places, form outlet powder 20.Inner high voltage gas 3 and outer high pressure gas 12 finish internal fluidisation powder 18 with outside after the fluidisation disturbance of fluidisation powder 19, upward movement passes powder 9, leaves the powder storehouse from the exhausr port 15 on body 1 top, powder storehouse, but before final exhaust to atmosphere, generally need purify by dust arrester installation.
Central area blanking 16 is in descending process, run into the inner high voltage gas 3 that enters into powder storehouse body 1 through interior air inlet pipe 6 and interior air-distribution device 4 in interior fluidizer 2 regions, density diminishes, be fluidized state, fluidisation powder 18 in becoming stops central area blanking 16 to form in this zone and puts up a bridge and perforation.Adherent regional blanking 17 is in descending process, air-distribution device 11 places run into the outer high pressure gas 12 that enter into powder storehouse body 1 through outer air-distribution device 11 outside, and density diminishes, and is fluidized state, become outer fluidisation powder 19, stop adherent regional blanking 17 to form and put up a bridge and perforation in this zone.
The difference of Fig. 3 and preferred embodiment shown in Figure 4 and preferred embodiment shown in Figure 1 is, the link span 5 of fluidizer 2 is different in supporting, in Fig. 1, fluidizer 2 supports in 5 pairs of the link spans, in Fig. 3, fluidizer 2 is hung in 5 pairs of the link spans, and in Fig. 4, fluidizer 2 supports simultaneously and hangs in 5 pairs of the link spans.
Fig. 6-Fig. 9 is respectively interior four preferred embodiment plan structure of fluidizer scheme drawing of the present invention, and four appearance profiles of overlooking are followed successively by triangle, circle, equilateral polygon, oblong, can certainly be other shapes.
In sum, in the present invention, enter the powder storehouse behind the air-distribution device in the inner high voltage gas of air inlet pipe is flowed through in coming from, the powder of pressing close to the conical suface outside is carried out fluidisation and disturbance, prevent that powder from putting up a bridge and perforation.The outer high pressure gas that come from the external admission pipe are flowed through and are entered the powder storehouse behind the outer air-distribution device, and the powder of pressing close to powder storehouse barrel is carried out fluidisation and disturbance, prevent that powder from putting up a bridge and perforation.Interior air-distribution device and outside under the combined action of air-distribution device, inner high voltage gas and outer high pressure gas carry out the fluidisation disturbance to the powder in the adherent zone of powder storehouse interior zone and powder storehouse respectively, can effectively avoid powder in descending process, to form bridging, perforation, effectively guarantee descending unobstructed, the smooth discharge of powder in the powder storehouse in bottom, powder storehouse.
As known by the technical knowledge, the present invention can realize by other the embodiment that does not break away from its spirit or essential feature.Therefore, above-mentioned disclosed embodiment with regard to each side, all is a casehistory, is not only.All within the scope of the present invention or the change in being equal to scope of the present invention all be included in the invention.
