Abstract
The utility model discloses a kind of fluid bed gas distribution grid, comprise circular plate body and passage, described passage is arc blast cap pore structure, this arc blast cap side direction perforate, and rule distribution ringwise on circular plate body.After gas tangentially imports, the utility model can make the material in fluid bed in rotating the screw of seething, and form cycline rule fluidization, fluidization of material is without dead angle.Blast cap is circular arc, can be shaping by mould punching, and punching Angle ambiguity, in the angle of repose of material, so both anti-leak-stopping material phenomenon can occur, and also met the requirement that percent opening is large.Arc blast cap hole on the utility model increases to outward flange gradually from circular plate body center, fluidised evenly with stable in guarantee bed, not only can realize solid granulation, drying, also be convenient to spiral discharging.
Description
Technical field
The utility model relates to a kind of gas distribution grid, particularly a kind of fluid bed multifunctional gas distribution grid.
Background technology
Fluid bed is the key equipment of the technology such as the granulation of solid pharmaceutical preparation industry, drying, dressing.In granulating process, enter fluid bed by the passage of hot-air on gas distribution grid, make solid material be boiling fluidisation state, contact with fluidised solid material after the material of atomization is sprayed into and bond, reach the objects such as drying, granulation, dressing.Fluidized bed gas distribution grid plays a part uniform air-flow and supports solid phase particles, is to ensure that fluid bed has important component that is good and stabilization of fluidized, and its structure and size significantly affect the Mass and heat transfer performance of operation.Traditional fluidized bed gas distribution grid is generally porous plate, namely on disk, opens multiple aperture, and gas axially enters, and easily causes flow blind angle.In addition, traditional fluidized bed gas distribution grid is only suitable for single technological process, needs to switch different distribution grid components, complex operation in fluidized drying, granulation, discharging process.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of fluidization of material without dead angle, do not need switching can realize the multifunctional gas distribution grids such as drying, granulation, discharging.
For achieving the above object, the utility model provides a kind of fluid bed multifunctional gas distribution grid, and this multifunctional gas distribution grid comprises a circular plate body, and this circular plate body is provided with passage, described passage is arc blast cap hole, and the blast cap opening in this arc blast cap hole is side direction.
Further, described passage distributes by annular rule on described circular plate body, and the quantity of passage increases to circumference gradually from circular plate body center.
Further, the arc opening in described arc blast cap hole is made up of multi-section circular arc.
The utility model has following characteristics: the utility model, after gas tangentially imports, by the water conservancy diversion in arc blast cap hole, can realize the spiral regular motion of gas, form stable fluidized state; Arc blast cap of the present utility model is shaping by mould punching, and blast cap is lateral openings, and opening radian is made up of multi-section circular arc, and angle is less than the angle of repose of material, avoids Lou expecting, and meets percent opening requirement; Arc blast cap hole of the present utility model increases to circumference gradually from circular plate body center, increases circumference tangential force, and it is even and stable that guarantee circulates.

Reference numeral: 1 circular plate body; 2 arc blast cap holes; 3 multi-section circular arcs.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Figure 1, a kind of fluid bed multifunctional gas of the utility model distribution grid comprises a circular plate body 1, and described circular plate body 1 is disk, and disc thickness is 2mm, and disk is provided with multiple arc blast cap hole 2, and the percent opening on circular plate body 1 is determined by material properties.After gas tangentially imports, by the water conservancy diversion in arc blast cap hole 2, the spiral regular motion of gas can be realized, form stable fluidized state.Arc blast cap hole 2 to circumference rule distribution ringwise from the center of circular plate body 1, and to increase gradually, adds circumference tangential force, ensure to circulate evenly with stable.As shown in Figure 2, described arc blast cap hole 2 is shaping by mould punching, and the blast cap in this arc blast cap hole 2 is lateral openings, and opening radian is made up of multi-section circular arc 3, and angle is less than the angle of repose of material, avoids Lou expecting, and meets percent opening requirement.
As shown in Fig. 3, Fig. 4, Fig. 5, the open height in the arc blast cap in arc blast cap hole 2 and the plate face of circular plate body 1 is determined by curved angle, and curved angle is generally less than material angle of repose.For the percent opening requirement of air inlet distribution grid, percent opening is 20% ~ 40%, and percent opening is large, and the resistance suffered by gas is little, makes the air-flow entering fluid bed unimpeded.For the embodiment of fluidized drying, particle diameter is 600 μm, and the percent opening of air inlet distribution grid is generally 30% ~ 40%, and the curved angle α in the side direction cambered surface in arc blast cap hole 2 and the plate face of circular plate body 1 is generally 35 ~ 40 °, cambered surface width b is generally 5 ~ 7.5mm, and length a is generally 12 ~ 17mm.For the embodiment of fluidized granulation, particle diameter is 300 ~ 600 μm, and air inlet distribution grid percent opening is generally 20% ~ 30%, and the curved angle α in the side direction cambered surface in arc blast cap hole 2 and the plate face of circular plate body 1 is for being generally 30 °, cambered surface width b is generally 4 ~ 5mm, and length a is generally 8 ~ 10mm.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
