Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises casing 3, is all connected with axle sleeve 13 at the middle part of its left and right sides wall, in two axle sleeves 13, be equipped with rotating shaft, between the inner of two rotating shafts, erection is provided with rotating cage, and Chinese medicine materials is placed in rotating cage and is moved by head end terminad.
Rotating cage comprises the helical screens 8 being positioned at outside cylinder screen 7 and being positioned at inside, core cylinder 10 is provided with for lift structure intensity at the center of helical screens 8, the outer ledge of helical screens 8 and the inwall of cylinder screen 7 affixed, therefore form a spirality channel passed through for Chinese medicine materials.End orifice plate 9, two end orifice plates 9 are all connected with affixed with rotating shaft respectively at the two ends of cylinder screen 7.
The left side wall of casing 3 is also provided with the air-heater 1 of the reductor 2 of drive shaft rotation and the inner chamber supply hot-air for casing 3.The exhaust duct 12 with axial flow blower 11 is provided with on the top of casing 3 right side wall.The hot-air that air-heater 1 produces enters the inner chamber of casing 3, under the effect of axial flow blower 11, hot-air has a lower left by casing 3 inner chamber to top-right flow path, at the material of middle heat air through rotating cage and inside thereof of this flow path, produce desiccation to Chinese medicine, dried humid air is discharged via exhaust duct 12.
The end orifice plate 9 of head end offers on charging aperture, rear-end end orifice plate 9 and offer discharging opening.Be provided with the material loading pipeline 4 extending to inner chamber on the top of casing 3 front side wall, within it end is connected with inclined ramp 5, and the inner of inclined ramp 5 is relative with the charging aperture of rotating cage.Be connected with below discharging opening that the inner extends to rotating cage in the bottom of casing 2 right side wall, guide slideway 15 that outer end extends to casing 3 outside.
The course of work: Chinese medicine materials to be dried is put into via material loading pipeline 4, Chinese medicine materials moves along inclined ramp 5, then enters the inner chamber of rotating cage via charging aperture, i.e. one end of spirality channel; Under gravity, Chinese medicine materials is settled down to the bottom of rotating cage, and in the process that rotating cage rotates, Chinese medicine materials advances in this spirality channel, until discharged by the discharging opening of rotating cage after drying; The material of above-mentioned discharge drops and enters guide slideway 15 and be expelled to outside casing 3, can arrange splicing basket 16 for splicing in the outer end of guide slideway 15.
In order to make hot blast be unlikely to waste, setting hot blast in this drying equipment and participating in cyclic drying process after dehumidifying.Particularly, be provided with return air inlet in the bottom of casing 3 rear wall, return air duct is set between this return air inlet and exhaust duct 12, axial flow blower 11 and humidity-discharging device 19 are set in return air duct.The moist hot blast of being discharged by exhaust duct 12 when humidity-discharging device 19, its steam contained be liquefied as drip and outside discharge line, the power that axial flow blower 11 provides above-mentioned circulating air to flow.
As shown in FIG., return air duct comprises the first air channel 18 be connected with exhaust duct 12 and the second air channel 20 be connected with return air inlet, docking is between connected with middle air channel, and wherein axial flow blower 11 is arranged in the second air channel 20, humidity-discharging device 19 is arranged in middle air channel.Humidity-discharging device 19 structurally comprises the housing through with middle air channel inner chamber and is located in this housing, to be connected with cooling medium cooling coil, arranges drainpipe in the bottom of housing, arranges steam-water separator in the end of drainpipe.
