As preferably, described deflector comprises the first deflector, the second deflector and the 3rd deflector that are connected to described expansion chamber inwall from front to back successively.
As preferably, described first deflector comprises hot blast shunting stage casing, shunt the up Drainage Section of hot blast that stage casing is connected with hot blast and shunt with hot blast the descending Drainage Section of hot blast that stage casing is connected.
As preferably, described hot blast shunting stage casing, just to described air inlet, has the first hot blast path between the up Drainage Section of described hot blast and described expansion chamber inwall top, has the second hot blast path between bottom the descending Drainage Section of described hot blast and described expansion chamber inwall.
As preferably, the vertical drainage segmentation that described second deflector comprises the horizontal drainage segmentation be connected with described expansion chamber inwall top, the bending drainage segmentation be connected with described horizontal segment and is connected with described bending Drainage Section, forms the first hot blast between bottom described vertical drainage segmentation and described expansion chamber inwall and crosses mouth.
As preferably, between described horizontal drainage segmentation and described first deflector, there is the first hot blast path and extend section.
As preferably, described 3rd deflector comprises and the vertical single hop be connected bottom described expansion chamber inwall, form the 3rd hot blast path between described 3rd deflector and described second deflector, form the second hot blast between described 3rd deflector and described expansion chamber inwall top and cross mouth.
As preferably, between described 3rd deflector and described air outlet, there is clearance space, described expansion chamber is also provided with the blower fan being positioned at described clearance space top and the steam generator coordinated with described blower fan.
As preferably, described drying device also comprises is located at the fluid-tight decanting zone that the end in described expansion chamber surrounds by described expansion chamber inwall and described 3rd deflector, and described fluid-tight decanting zone respectively and described first deflector foot, there is gap between described second deflector foot.
As preferably, described expansion chamber has bottom discharge mouth, and described bottom discharge mouth is provided with excretory duct and the bleed valve for controlling described drain pipe opening and closing.
Technological merit of the present invention is that described bentonite drying device structure is simple, easy to use, can by abundant for original hot blast impurity and purification, cigarette ash carried out concentrated sedimentation while to the reasonable drainage of hot blast and absorb, and utilize steam wind to carry out final distinguished and admirable mixing temperature adjustment and impurity to blow and fall, heated-air drying proper temperature, drying effect is good, and product quality improves.

Detailed description of the invention
Below in conjunction with accompanying drawing, by specific embodiment, the invention will be further described:
See Fig. 1, a kind of bentonite drying hot air apparatus of high-efficiency environment friendly, the material slewing equipment comprising hot air apparatus and coordinate with hot air apparatus, also comprise hot blast sedimentation device, hot blast sedimentation device comprises one end and is provided with the air inlet 11 that is communicated with hot air apparatus and expansion chamber 1 that the other end is provided with the air outlet 12 be communicated with material slewing equipment and the deflector be located in expansion chamber 1.Deflector comprises the first deflector 13, second deflector 14 and the 3rd deflector 15 that are connected to expansion chamber 1 inwall from front to back successively.Expansion chamber 1 has bottom discharge mouth, and bottom discharge mouth is provided with excretory duct 17 and the bleed valve 18 for controlling excretory duct 17 opening and closing.
First deflector 13 comprises hot blast shunting stage casing 131, to shunt the up Drainage Section of hot blast 132 that stage casing 131 is connected with hot blast and shunt with hot blast the descending Drainage Section 133 of hot blast that stage casing 131 is connected.Hot blast shunting stage casing 131, just to air inlet 11, has the first hot blast path 2 between the up Drainage Section 132 of hot blast and expansion chamber 1 inwall top, has the second hot blast path 3 between bottom the descending Drainage Section 133 of hot blast and expansion chamber 1 inwall.
