Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment: a kind of novel fluidized bed drying device, its structure can with reference to shown in figure 1: comprise casing 2, casing 2 inner horizontal is provided with the air distribution plate 8 of multiple airtight connection, is air intake passage 9 between the bottom of air distribution plate 8 and casing 2, is hothouse 12 between the top of air distribution plate 8 and casing 2.
One end of air intake passage 9 protrudes from casing 2, is charging aperture 11, and charging aperture 11 is provided with flutter valve 10, and the pulsed realized to hothouse 12 is blown.
In above-mentioned casing 2, the left end at top is provided with a charging aperture 1, and middle position and the position of keeping right at top are respectively equipped with an air outlet 4, and charging aperture 1 is all connected with hothouse 12 with air outlet 4, and the right side of casing 2 is the passage 5 that gathers materials.
In hothouse 12, in order to improve turbulence effects, be also provided with multiple baffle plate 3.The length of adjacent baffle plate 3 is different, is long baffle plate and short shutter respectively, and long baffle plate and short shutter interval are arranged.
As preferably structure, the discharge valve 7 that controls Flow of Goods and Materials is all installed between all long baffle plates and air distribution plate 8.As another kind of structure, also the discharge valve 7 that controls Flow of Goods and Materials can be installed between all short shutters and air distribution plate 8, by the flow regulating the aperture of discharge valve 7 to control material.
With the junction of casing 2, filter 13 is installed at described air outlet 4, when preventing the wind after dried material from flowing out from air outlet 4, material is taken out of.
Shown in figure 2: air distribution plate 8 is provided with multiple row exhaust vent, often list air holes towards identical, the direction of the exhaust vent of adjacent column is contrary.
Specifically, the total columns of the exhaust vent 14 on air distribution plate 8 is odd column, and exhaust vent 14 part is towards discharging opening 6, and another part is towards charging aperture 1; Exhaust vent 14 towards discharging opening 6 is 3:2 with the ratio of exhaust vent 14 columns towards charging aperture 1, and the center line of exhaust vent 14 and the angle of air distribution plate 8 plane are 45 °-65 °, and the size of each exhaust vent 14 is 5-10 order, and the thickness of air distribution plate 8 is 5-8mm.
Certainly, according to different materials, also may there is certain difference in the specification of air distribution plate 8.
Shown in figure 1-3: material enters from charging aperture 1, dry hot nitrogen enters air intake passage 10 from air inlet 11, then after air distribution plate 8 cloth wind, flows to hothouse 12.Nitrogen continues to flow into, the direction then having the nitrogen of 3/5 to flow to material advance is blown (namely flowing to discharging opening 6), have the air-flow of 2/5 to blow (namely flowing to charging aperture 1) to material contrary direction of advancing, the airflow direction of intersection makes material at hothouse 12 inner drying until be in turbulence state before entering the passage 5 that gathers materials always.By being provided with flutter valve 10 at air inlet, so can realize realizing pulsed air-supply in hothouse 12.
Because there is the existence of baffle plate 3, so in fact hothouse 12 is separated into multiple little hothouse, further increase turbulence effects.
Nitrogen after drying completes, after flowing out, can collect, deliver to nitrogen drying tower from air outlet 4, processes qualified Posterior circle and uses.
Consider for the angle improving drying effect, also can heat-insulation layer be set at the inwall of casing 2.
After have employed said structure, material flows according to the direction of charging aperture 1, hothouse 12, gather materials passage 5 and discharging opening 6 successively, dried hot nitrogen is continued dry in the process of flowing, and for turbulence state, prevent the adhesion of material thin slice, to gather and be heated the situations such as irregular generation variable color, effectively ensure carrying out smoothly of concerned process steps.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of embodiment, General Principle as defined herein can be without departing from the spirit or scope of the present invention, realize in other embodiments, the part be not described in detail, for prior art, do not repeat at this.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and feature.
