Reference picture 2,3, existing ciculation fluidized, material is deposited on sieve plate 16, and bottom air can be entered by sieve plate 16,
Material will not fall into lower section by sieve plate 16, need individually to take out the disengaging bed of material when drying and completing discharging, manually from top
Material is scooped out, this way wastes time and energy, and material cleaning is not clean, edge Yi Liu dead angles, easily causes sieve plate for a long time
16 block.Recirculating fluidized bed 1 provided in an embodiment of the present invention, sieve plate 16 is made rotary type, sieve plate 16 is by rotating shaft and outside
Portion is connected, and is externally connected to drive mechanism, and drive mechanism can be pneumatic, electronic, or even ting model can also be manual, and discharging is completed
Afterwards sieve plate 16 rotate 0 ° -90 ° it is adjustable, material falls into lower section wind inlet section bottom, can be with 20 external drive mechanism of rotary shaft
Shake, the material remained on sieve plate 16 is shaked off.Improvement is have also been made at air inlet 7, in side, bottom sets one and gone out air inlet 7
Material mouth 17, discharging opening 17 is in closed mode when usually equipment is run, and need to only open discharging opening 17, the wind meeting of air inlet 7 during discharging
Material is blown out from discharging opening 17, completes discharging.This novel discharging formal operations are simple, can automate implementation, and discharge
Residual is few, accomplishes that material, artificial binodal save.
Need individually to split out the disengaging bed of material when material discharges, fluidisation state section adjacent thereto and air intake fragment position are all
Fixed, so need the gap with cylinder push-tight exhaustion section, input and output material section 9 and fluidisation state section to complete to seal, this difficult sealing
Degree is big, easily leakage, and the seal form such as traditional pad, O-ring is difficult to sealing gasket being quickly installed to specified location.This
Invention sieve plate 16 is improved to rotate 0-90 DEG C of adjustable, the corresponding sealing area of sieve plate 16 improvement, in being with rotary shaft 20
Line, the right and left are in respectively full state in the upper and lower of sieve plate 16 arrangement gas-flow closure circle 19, non-discharging, prevent material from this
Place's leakage.Simultaneously using existing rubber ring inflation technology, the sealing ring pattern that rubber ring is customized to need, installed in each section
Between flange, gas-flow closure circle 19 is connected with inflation exhaust outlet 21, and seal process is realized by being filled with discharge compressed air.Tear open
Dress is quick, saves artificial and good sealing effect, is advantageous to the big occasion of sealing off gap.
And improved for sealing problem, discharging sieve plate 16 is improved to rotate 0 ° -90 ° adjustable, corresponding sieve plates 16
Sealing is center line with rotary shaft 20, and the right and left is respectively in the upper and lower ladder of sieve plate 16 arrangement gas-flow closure circle 19, non-discharging
In full state, prevent material from leaking from there.Recirculating fluidized bed 1 provided in an embodiment of the present invention uses existing rubber simultaneously
Inflation technology is enclosed, the sealing ring pattern that rubber ring is customized to need, between each section of flange, by being filled with discharge compression
Air realizes seal process.Recirculating fluidized bed 1 is passed in and out into the bed of material sealing cylinder encryption seal sealing is changed to by cylinder seal, it is close
Seal realizes seal process using rubber ring inflation technology by being filled with discharge compressed air.So sealing is more stepped up
Close, leakage reduces.
In addition, the drive mechanism for driving rotary shaft 20 to rotate is provided with the outside of input and output material section 9.
It should be noted that being externally connected to drive mechanism, drive mechanism can be pneumatic, electronic, or even ting model may be used also
With manual, 0 ° -90 ° of the rotation of sieve plate 16 is adjustable after the completion of discharging, and material falls into lower section wind inlet section bottom, external in rotary shaft 20
It can also be shaken in drive mechanism, the material remained on sieve plate 16 is shaked off.
Also, recirculating fluidized bed 1 also includes：Fillter section 8；Flat filter net 13 is provided with the barrel of fillter section 8, and
Axial direction of the flat filter net 13 along fillter section 8 is configured.And the lower end of fillter section is provided with charging aperture 10.
Reference picture 1, the existing ciculation fluidized height of fillter section 8 is very high, and fluidizes state section insufficient space, causes dry materials to imitate
Fruit is bad, and screen pack and fluidisation state segment distance are small, and filter pressure is big, need to improve.It is provided in an embodiment of the present invention ciculation fluidized
The filter of the flat filter net 13 and existing recirculating fluidized bed 1 of bed 1 is different, the filtering dress of existing recirculating fluidized bed 1
Put and formed more using multigroup Cylindrical filter net, screen pack is arranged perpendicular to the ground, and total height is about at 1 meter or so, and the present invention is real
The filter for applying the recirculating fluidized bed 1 of example offer uses flat filter net 13, and individual layer or more can be arranged according to different operating modes
Layer plane screen pack 13, reduce filtering mesh number so that flour dust overflow is reduced, and improves dedusting particle diameter.
In addition, being provided with vibrator 14 along the circumferential edge of flat filter net 13, thing on flat filter net 13 is prevented
Material accumulation.
Specifically, the edge of flat filter net 13 placement vibrator 14, vibrator 14 drive flat filter net 13 to vibrate, avoided
Solid accumulation influences the problem of filter area on flat filter net 13, and this improvement reduces the space-consuming of fillter section 8, in increasing
Between fluidize the space in state region, make the lengthening distance of boiling state material anomaly face screen pack 13, mitigate screen pack pressure, improve thing
Expect drying effect.Specifically it can be used for vibrator 14 and pneumatically or electrically be used as power.
In addition, spray ball 18 is provided with the lower end of flat filter net 13.
It should be noted that improving the problem of existing recirculating fluidized bed 1 cleans complexity, existing fluid bed is when one section
Between need filter bag splitting out cleaning, the present invention makes filtering into flat filter net 13 form, can use that to install spray ball 18 additional clear
Wash, realize that equipment on-line cleans.
Second aspect, a kind of circulating fluidized bed system provided in an embodiment of the present invention, including：Air-introduced machine 2 and first aspect
