Abstract

The utility model relates to a feeding scattering machine of fluidized bed, belonging to feeding auxiliary device of fluidized bed, which is characterized in that a basic unit, namely a scattering rotating drum is a hollow cylinder welded outside of a shaft sleeve coaxially and a plurality of sharp protrusions are firmly welded on the outter wall of the scattering rotating drum; the two ends of the shaft sleeve are fixed on a shaft by bolts to form a component A and the component A is horizontally arranged in a feeding box 6 with a feeding downspouting 7 arranged above and a horizontal outlet K1 slotted on the sidewall; the feeding box 6 is fixed on the wall 9 of feeding end of the fluidized bed by bolts and the outlet K1 aligns the feed opening K2 of the fluidized bed on the wall 9. The material L entering from the downspouting 7 can fall on the rotating drum 3 rotating in a high-speed driven by a motor, and then be scattered upwards the fluidized bed and at last fall on the fluidized bed in a wide range of area.

Description

The fluid bed charging machine that scatters

The utility model by name " fluid bed charging scatter machine " belongs to charging auxiliary device grain fluidized bed in physics, the chemical process equipment.

For the bigger continuous handling fluid bed of material handling amount, in particular for the fluid bed dry, that the charging water capacity is very high, the dispersal of feed situation has significant impact to fluidized bed process.Disperse measure, concentrate on a large amount of feeding in raw material in the long-pending scope of the very little bed surface of feed end as if no actv., will cause bad, the windrow of feed zone local fluidization, fluctuation of service; For the fluid bed dryer of handling high water capacity material, be easy to form caking at the intensive position of charging, cause " dead bed ", make the operating cycle become very short, and the cleaning of stopping will be wasted a large amount of manpowers, also make unit consumption of energy increase greatly.Do not see as yet that before this actv. dispersal of feed device is used for industrial fluidized bed.Existing measure or the device that tackles the problems referred to above mainly contains following two kinds: smash the material of forming agglomerate with crusher earlier before (1) charging, increase the charging width simultaneously, the heavy soda ash calcining machine of for example external Suhl longevity company's manufacturing.Because charging is still more concentrated after increasing width, and advance to smash agglomerate before the fluid bed and can not prevent to form in the fluid bed agglomerate effectively, this measure is very ineffective, and the charging position is easy caking still; And for making the cleaning caking comparatively convenient, its fluid bed feed space is not installed heat exchanger tube, has wasted a part of heat transfer space.(2) mixer is installed in the feed end fluid bed, is promptly made forced fluidized bed.This method makes device structure complicated, increases investment; And the mixer as wheel word is at high temperature worked, and is more fragile, and installation, maintenance is also difficult.Do not see as yet in addition other similar patented technology is arranged.

The purpose of this utility model is the deficiency that overcomes above-mentioned measure and device, and a kind of effective and easy fluid bed dispersal of feed device is provided.

Fig. 1 is the utility model fluid bed charging machine agent structure section-drawing that scatters; Fig. 2 is its internal organs view; Fig. 3 is scatter material distributing machine and fluid bed assembly relation generalized section.

Below in conjunction with accompanying drawing, content of the present utility model and implementation method are described.

The fluid bed charging the most basic parts that the machine main body comprises that scatter are the rotary drums 3 that scatter, and its outer wall is abound with the sharp projection thing 4 of a lot of firm welding.Sharp projection thing shown in Fig. 1 and Fig. 2 is sharp triangular plate; They also can replace with thicker wire, the hard nail of inversion or other object with similarity.Rotary drum 3 bodies that scatter are hollow cylinders, and it becomes whole with axle sleeve 2 coaxial welding, and at both ends is fixed to axle sleeve 2 on the axle 1 together with the rotary drum 3 that scatters with ending hook bolt 5; Also can adopt alternate manner that axle sleeve 2 firmly is connected with axle 1 with the rotary drum 3 that scatters.

Scatter machine and fluid bed assembly relation of charging seen Fig. 3.Rotary drum 3 and the axle sleeve 2 that scatter is installed in the material feeding box 6 with axle 1 an assembly set A on even keel that connects into; Material feeding box 6 tops are provided with chute 7; Sidewall has horizontal oblong outlet K1, its width and highly all surpass the rotary drum 3 that scatters, and the lower edge of mouth flushes with at the bottom of the case, to avoid piling up material.Casing 6 is fixed on the inlet end wall 9 of fluid bed by tie bolt 8.The outlet K1 of material feeding box 6 is alignd with fluid bed inlet point K2 on the fluid bed inlet end wall 9.Open drive motor (all not drawing among Fig. 1,2,3) during use earlier, drive the rotary drum 3 synchronous high-speeds rotation that scatters by axle 1; Pass through chute 7 chargings of material feeding box 6 tops subsequently.Material L drops to from chute 7 on the rotary drum 3 that scatters of high speed revolution and is broken up and shed, and enters the fluid bed top by the Horizontal Exit K1 of material feeding box 6 and the fluid bed inlet point K2 on the fluid bed inlet end wall 9, is scattering in the fluid bed.Under high speed revolution, the granule materials of breaing up be broken up and be shed to the rotary drum 3 that scatters can to the loose agglomerate material of falling on it, makes it to be distributed on the direction perpendicular to axle 1 certain length range; If sharp projection thing 4 adopts sharp triangular plate form, they are welded on rotary drum 3 outer walls that scatter with suitable angle ground, they can also produce horizontal thrust to material during rotation, make it horizontal spread, and the expansion material falls into the area of fluid bed.

Compare with aforementioned existing measure or device, the utility model fluid bed charging facility that scatter have following advantage: it is very effective that material is broken up and shed in (1), can be distributed to charging on the very broad fluidized bed area, avoid the concentrated local windrow that causes of charging and " dead bed ".(2) material is broken up and shed to direct momentum transfer between sharp projection thing on the rotary drum outer wall that scatters of dependence high speed revolution and the material, the energy efficiency height, and consumption of power is than other measure or install low.(3) actv. dispersed material homogenizing the fluid bed load, make fluidized bed process more stable.

Claims (1)

1. The scatter charging auxiliary device of machine of a kind of fluid bed charging by name is characterized in that the basic element of character is and the rotary drum 3 that scatters of axle sleeve 2 coaxial firm welding, and its outer wall is abound with the sharp projection thing 4 of firm welding; They are fixed on by the hook bolt 5 that ends at axle sleeve 2 two ends that the assembly A level that forms on the turning cylinder 1 is mounted thereto to be had in the material feeding box 6 that charging chute 7, sidewall have outlet K1, material feeding box 6 is fixed by bolts on the fluid bed inlet end wall 9, and its discharging opening K1 aligns with fluid bed inlet point K2 on the wall 9.
