Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the broken section of air-flow sedimentation drying machine of the present utility model;
Fig. 2 when to be that Fig. 1 is actual use air-flow move towards schematic diagram.
The specific embodiment
Fig. 1 has provided a kind of air-flow sedimentation drying machine, comprises cylindrical shell, and this cylindrical shell is made up of the divergent-cone wall 1 that is connected successively from top to bottom, straight shape cylindrical shell 2 and inclined to one side divergent-cone wall 3.The top of divergent-cone wall 1 is connected with tail airduct 16.The bottom of divergent-cone wall 3 is connected with the top of discharge nozzle 4 partially, in the bottom of discharge nozzle 4 discharging opening 5 is set.Outer surface at straight shape cylindrical shell 2 is provided with ear seat 10, utilizes this ear seat 10, whole air-flow sedimentation drying machine can be fixed on actual desired location.
Being provided with end face in the inner chamber of straight shape cylindrical shell 2 does not have bucket 13 in bottom surface inverted, and bucket 13 is fixedly linked by inner surfaces of bracing frame 15 and divergent-cone wall 1 in this; Bucket 13 hangs on the below of tail airduct 16 promptly through bracing frame 15.Fix more firmly for bucket 13 in making in the inner chamber of straight shape cylindrical shell 2, interior bucket 13 also is fixedly linked by the inner surface of stull 11 with straight shape cylindrical shell 2; End face of bucket 13 is a conical top surface 14 in this.
The inner chamber that is arranged in straight shape cylindrical shell 2 behind the side of inclined to one side divergent-cone wall 3 is passed through on the top of drying tube 8; The top of drying tube 8 be positioned at the bucket 13 under; The bottom of the top of drying tube 8 and interior bucket 13 maintains a certain distance.More firmly stable in order to make between drying tube 8 and the whole cylindrical shell, between the outer surface of the outer surface of drying tube 8 and inclined to one side divergent-cone wall 3, support 9 is set.The bottom of drying tube 8 is provided with Lou material mouth 6, is provided with charging air inlet 7 on drying tube 8, and this charging air inlet 7 is near the bottom of drying tubes 8.The central axis overlaid of tail airduct 16, divergent-cone wall 1, straight shape cylindrical shell 2, conical top surface 14, interior bucket 13, drying tube 8.
The internal diameter of straight shape cylindrical shell 2 is 2～8 times with the ratio of the internal diameter of drying tube 8, and the internal diameter of interior bucket 13 is also greater than the internal diameter of drying tube 8.Air-flow is when drying tube 8 comes out to enter straight shape cylindrical shell 2 like this, and its flow velocity is reduced to original 1/4～1/64; Air-flow after flow velocity reduces greatly, its powder that carries can be realized and the separating of air-flow because of the powder self gravitation.
Air-flow sedimentation drying machine practical work process of the present utility model is as follows:
16 places are provided with air-introduced machine at the tail airduct; Carrying secretly needs the thermal current of dry granular material to enter drying tube 8 with certain speed from charging air inlet 7, in the thermal current of granular material dispersion suspension in drying tube 8; Along with the rising of thermal current in drying tube 8, granular material has been carried out dry processing.Dry powder along with thermal current after the top ejection of drying tube 8, continuous and enter be positioned at drying tube 8 tops directly over bucket 13.In bucket 13 owing to have conical top surface 14, so after air-flow was subjected to the rebound effect of conical top surface 14, the bottom from interior bucket 13 gushed out again, enters in the straight shape cylindrical shell 2.Therefore, interior bucket 13 is to play the effect that stops, purpose is that the air-flow that carries powder is evenly diffused in the whole straight shape cylindrical shell 2, and the high velocity air of avoiding drying tube 8 tops to come out " is walked short circuit " and directly taken away through tail airduct 16 by air-introduced machine; Thereby reduce the discharge rate of powder, promptly improved the effect of sedimentation separation with tail wind.
Because the internal diameter of straight shape cylindrical shell 2 is greater than the internal diameter of drying tube 8, therefore, the thermal current speed of carrying the dry powdery material secretly that rises reduces, the dry powdery material is because himself gravity, can't be blown afloat by low velocity gas, thereby fall down, the overwhelming majority is discharged through discharging opening 5 from discharge nozzle 4, few part falls into drying tube 8, can discharge from leaking material mouth 6 at last.Tail gas after powder separates is taken away from tail airduct 16 at last.
