The device of the method is composed of a gas compressor, a rotary butterfly valve, a screw feeder and the spreading device, wherein a gap is formed between a valve sheet and the valve body of the rotary butterfly valve; a rotating shaft of the valve sheet is connected with a motor; the spreading device is composed of an outer cylinder, a central ventilating pipe, an impeller and blades; the impeller and the central ventilating pipe are firmly welded; the blades are arranged in the impeller; the circumference of the impeller is provided with an annular nozzle; the screw feeder is connected to the outer cylinder; the central ventilating pipe is firmly welded on the outer cylinder. The present invention has the advantage of uniform spread.

Description

The method of distributing granule materials evenly and device thereof

The present invention relates to a kind of method and device thereof of distributing granule materials evenly, be mainly used in the coal utilization technological process.As evenly sowing of destructive distillation feed coal in the gazogene, and evenly the sowing of storages such as granule materials such as seed.

Sowing of existing granule materials is owing to lack the method and apparatus of evenly sowing.Its weak point is: it is promptly up-small and down-big that the granule materials of sowing out is piled into cusp configuration, causes sowing inhomogeneous.

The objective of the invention is to overcome above-mentioned weak point of the prior art and provide a kind of granule materials that makes to sow method and device thereof that the homogeneous granules material is evenly sowed.

Purpose of the present invention can reach by following measure: method of the present invention is: make pressure gas by rotating butterfly valve, the size that obtains pressure and flow is continuous and periodically variable air-flow, annular nozzle ejection through seeding device, to enter urceolus and the granule materials between the central aeration pipe of urceolus central authorities is sowed away from bypass, sow uniform purpose to reach, there is axial distance impeller base plate and urceolus lower end, and this is apart from the height of looping spout.

Device of the present invention is by gas compressor, trunk line, the rotation butterfly valve, screw feeder and seeding device are formed, gapped between the valve block of rotation butterfly valve and the valve body, the valve block S. A. connects with motor, seeding device is by urceolus, central aeration pipe, impeller and blade are formed, central aeration pipe is positioned at urceolus central authorities, the upper end of central aeration pipe is communicated with trunk line, impeller and central aeration pipe solid welding, the impeller internal fixation is connected with blade, around the impeller annular nozzle is arranged, there is axial distance impeller base plate and urceolus lower end, and this is apart from the height of looping spout, screw feeder is fixedly connected on the urceolus, and central aeration pipe is welded on the urceolus by attaching parts.

The drawing of accompanying drawing is described as follows:

Fig. 2 is the cutaway view of seeding device hypomere of the present invention;

Fig. 3 is the A-A cutaway view of Fig. 2, expression be the dismounting remove horn body 18 structure;

The invention will be further described below in conjunction with embodiment and accompanying drawing:

The method of distributing granule materials evenly is referring to Fig. 1-Fig. 6.Pressure gas from gas compressor 1, by the rotation butterfly valve 3 on the trunk line 5, the size that obtains pressure and flow is continuous and periodically variable air-flow, this air-flow is through annular nozzle 11 ejections of seeding device 4, to enter urceolus 6 by screw feeder 9 and the granule materials 21 between the central aeration pipe 7 of urceolus central authorities is sowed away from bypass, to reach the purpose of evenly sowing.There is axial distance impeller base plate 19 and urceolus 6 lower ends, and this is apart from the height of looping spout 11.

The device of distributing granule materials evenly is made up of trunk line 5, gas compressor 1, buffering gas tank 2, rotation butterfly valve 3, hopper 8, screw feeder 9 and seeding device 4 referring to Fig. 1-Fig. 6.Gas compressor 1 provides pressure gas after the pressure boost for trunk line 5, and the kind of gas is different and different with purposes, and it is to be used for evenly sowing of coal in the gazogene that air and coal gas etc., present embodiment are arranged, employing be coal gas.Gas compressor 1 is decided according to different media, as adopting piston compressor, buffering gas tank 2 should be arranged also behind this compressor; As adopt centrifugal compressor, then need not cushion gas tank.Rotation butterfly valve 3 is different with existing butterfly valve structure, and valve block and valve body that the first has butterfly valve now are leak free substantially, promptly rotates to line of centers with trunk line 5 when vertical when valve block, and trunk line is by base closed and obstructed.Between the valve block 13 of rotation butterfly valve of the present invention and the valve body 14 is gapped, and when promptly valve block was perpendicular to the trunk line line of centers, gas still can pass through, and just the pressure and the flow of air-flow reduce.It two is that S. A. 15 tops of valve block 13 are connected with motor 17 by coupler 16, can drive valve block 13 like this behind the starter motor and rotate in valve body 14.After the air communication of present embodiment was crossed the rotation butterfly valve, the pressure of air-flow and flow between maximum pressure Pmax and minimum pressure Pmin, and between correspondingly the maximum flow Qmax and minimum flow rate Qmin, were continuously and Fig. 4 is seen in cyclical variation.

The structure of seeding device 4 is referring to Fig. 1-Fig. 3, form by urceolus 6, central aeration pipe 7, blade 10 and impeller 12, central aeration pipe is welded on the urceolus by attaching parts 23, the attaching parts of present embodiment is that three gussets see that the two point of Fig. 3 draws shown in the dotted line, gusset is positioned at the below that screw feeder is connected in the urceolus position, can't see on Fig. 2, so, on Fig. 3, be represented by dotted lines.Impeller comprises horn body 18 and base plate 19, horn body upper end and central aeration pipe solid welding, central aeration pipe is positioned at urceolus central authorities, the upper end of central aeration pipe is communicated with trunk line, be fixedly connected with blade between the horn body of impeller and the base plate, around the wheel bottom annular nozzle 11 is arranged, there is axial distance impeller base plate and urceolus lower end, and this is apart from the height of looping spout 11.Pressure gas in the trunk line enters the impeller upper end by central aeration pipe, outwards sprays through annular nozzle by each interlobate cavity then.The seeding device side has screw feeder 9 and motor 20, and there is hopper 8 the screw feeder top.Starter motor 20, granule materials 21 in the hopper enters in the urceolus and the cavity between the central aeration pipe of seeding device by screw feeder, sow in the container 22 under the promotion of annular nozzle ejection air-flow, the container 22 of present embodiment is the inner chamber of gazogene.When annular nozzle 11 promoted granule materials and sows with maximum pressure (maximum flow) air-flow, just can spreading becoming with ultimate range Rmax was that the material ring of radius is seen Fig. 5 and Fig. 6.When annular nozzle is sowed with minimum pressure (minimum flow rate) air-flow promotion granule materials, can spreading one-tenth be the material ring of radius just with minor increment Rmin.Be continuously by the intermediate value of curve shown in Figure 4 between annular nozzle is with maximum and minimum pressure and circulation change when sowing granule materials, just can reach the purpose of evenly sowing, the granule materials heap after sowing looks like shown in Figure 6.

The present invention contrasts prior art and has following advantage: can sow evenly.
