As shown in Figure 1 to Figure 3, the embodiment of the invention provides a kind of fluidized bed distribution grids comprising distribution grid ontology
1, as shown in figure 3, be distributed with that several axis with the distribution grid ontology 1 are inclined to set on the distribution grid ontology 1 opens
Hole 2, specifically, the aperture 2 tilt from bottom to top from inside to outside on the distribution grid ontology 1.Therefore, when wind is from distribution grid
When ontology 1 is blown from bottom to top, it can make wind after distribution grid, the direction of wind changes, inclined direction of the wind along aperture
Helically state rotates into the material bin above distribution grid, and the material in material bin is made to be fully rotatable boiling；Pass through aperture 2
It is obliquely installed, distribution grid ontology 1 can be made full use of, it, can compared to vertical holes is opened up on the distribution grid of same area
It is high to realize 2 rate of aperture, and without dead angle, achievees the purpose that material is sufficiently dry.
In the embodiment of the present invention, each aperture 2 and the axis angle of the distribution grid ontology 1 are 30~55 degree,
Angle is preferably 45 degree, can make wind from bottom to top by the setting of this angle and be in divergent shape to be blown into material bin with optimal angle
In, so that material is fully rotatable and dries.
In the embodiment of the present invention, in order to avoid feed blocking aperture 2, the shape of each aperture 2 is in the distribution
Elongated on the surface of plate ontology 1, elongate holes are not easy by feed blocking, and more difficult material leakage.
In the embodiment of the present invention, the width of the aperture 2 is 0.2~0.4 millimeter, the length of the aperture 2 is 70~
110 millimeters, as shown in Figure 1, aperture thus set 2 is in fine crack shape, more difficult material leakage, due to opening on distribution grid ontology 1
Hole 2 is in a line from aperture 2 seen in fig. 1 than comparatively dense, but this is only schematic diagram, and actually aperture 2 is to have the gap
, only gap very little, granular material will not block aperture 2, and have biggish gap to enter the wind.
In the embodiment of the present invention, as shown in Figure 1, the distribution grid ontology 1 is rounded perpendicular to the section of its axis, if
The radial direction that the aperture 2 is done along the distribution grid ontology 1 is arranged in divergent shape, and is placed with each radial direction point of the aperture 2
Multiple spaced apertures 2 are furnished with, to make full use of the space on the distribution grid ontology 1, are opened up as far as possible more
Aperture 2, to guarantee sufficiently large intake and avoid generating dead angle.
In the embodiment of the present invention, specifically, between the aperture 2 that the distribution grid ontology 1 is each radially arranged
Gap and adjacent radial on gap between the aperture 2 arranged be in staggered distribution, so that multiple gaps be avoided to gather one
It rises and forms biggish gap, can also make to enter the wind more uniform, the dead angle easy to form at larger gap in this way, by will be each
A small―gap suture is in staggered distribution, and avoids the formation of larger gap, to avoid forming dead angle in material bin, and leads to dead angle area
Material cannot be fully rotatable；It not only can guarantee the intensity of distribution grid in this way, but also be conducive to each hole and uniformly arrange.
In the embodiment of the present invention, at the axle center of the distribution grid ontology 1, the aperture 2 is from apart from the distribution
Start to arrange at axle center a distance of plate ontology 1, which can be 150~180 millimeters, thus in distribution grid ontology 1
Formation one is removable on the disc using this section of distance as the border circular areas for the being not provided with aperture 2 i.e. disc of radius at center
It is connected with tapered cylinders with unloading, intermediate tapered cylinders and distribution grid can use screw connection, in addition after tapered cylinders, from stream
Changing the wind that bed Lower Hold is come in can rotate upwards along tapered cylinders, be more advantageous to material and boil upwards.In addition, this distribution grid is more
Be conducive to Vacuum discharge, material passes through after fluidized bed, can connect Vacuum discharge pelletizing machine, the setting of fluidized bed Vacuum discharge mouth
Above distribution grid, in this way, material is moved up along tapered cylinders, it is cleaner to be more advantageous to Vacuum discharge.
In the embodiment of the present invention, arrangement of the aperture 2 on the distribution grid ontology 1 is close in aperture 2 from inside to outside
Degree become larger from small, the surface area on distribution grid ontology 1 is in change from small to big from inside to outside, as a result, according to distribution grid ontology 1 the characteristics of
Aperture 2 is set, the region of distribution grid ontology 1 from the inside to the outside can be made full use of, be capable of increasing 2 rate of aperture, keep material abundant
Boiling.
The embodiment of the present invention also provides a kind of fluidized bed comprising fluidized bed Lower Hold and material bin and such as above-mentioned technical side
Fluidized bed distribution grid described in case, the fluidized bed Lower Hold, fluidized bed distribution grid and material bin successively connect along airflow direction
Logical setting.By that, with inclined aperture 2 is distributed on distribution grid, can make wind after distribution grid, the direction of wind in fluidized bed
It changes, along the inclined direction of aperture 2, helically state rotates into the material bin above distribution grid wind, makes in material bin
Material be fully rotatable boiling；Therefore it is more advantageous to Vacuum discharge, material is directly sucked in discharging container, and (usually vacuum goes out
Expect pelletizing machine) in or with the other machines that drying machine directly docks, be more advantageous to realize closed dust-free metaplasia produce.In addition, logical
It crosses and is detachably connected with tapered cylinders on the center disc of the distribution grid ontology, the wind come in from fluidized bed Lower Hold can edge
Tapered cylinders rotate upwards, be more advantageous to material and boil upwards.In addition, this distribution grid is more advantageous to Vacuum discharge, material
After fluidized bed, Vacuum discharge pelletizing machine can connect, fluidized bed Vacuum discharge mouth is arranged above distribution grid, in this way,
Material is moved up along tapered cylinders, and it is cleaner to be more advantageous to Vacuum discharge.
As can be seen from the above embodiments, the present invention can be such that material sufficiently boils by the setting form change to aperture
It rises, and without dead angle, the percent opening of distribution grid is high, achievees the purpose that material is sufficiently dry.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
