Accompanying drawing explanation
Fig. 1 is the schematic diagram of flat paddle dryer.
Fig. 2 is the schematic diagram of drying means.
The specific embodiment
As shown in Figure 1, flat paddle dryer comprises cylindrical shell 2, agitating device 3, drive unit 1, outlet valve, dust arrester 4.Flat paddle dryer need coordinate air heat dehydrating unit 5 when production and application.Cylindrical shell 2 outer surfaces are with steam or conduction oil chuck 9, the highest heating to 300 ℃.During equipment work, high water-containing materials enters after flat paddle dryer by dosing device (not illustrating in the drawings), under the High Rotation Speed effect of agitating device 3, with the abundant transmission of heat by contact of cylindrical shell 2 inwall, and gradually to the discharge end motion of cylindrical shell 2, in whole process, the moisture of material, by evaporation gradually, reaches final drying effect.The aqueous vapor of evaporation, under the drive of the inner heated drying air of flat paddle dryer, enters and reclaims secondary cycle utilization after dust arrester 4.Whole equipment takes full advantage of the advantage of conduction transmission of heat by contact and convection heat transfer' heat-transfer by convection, utilizes hot gas to reclaim the object of accomplishing energy-saving and emission-reduction simultaneously.
In conjunction with Fig. 1 and Fig. 2, by aforementioned flat paddle dryer, be appreciated that drying means of the present utility model, work starts first to start cylindrical shell 2 chuck heating in addition, makes cylindrical shell reach dry required technological temperature.Start air dewetting heater 5, make in equipment barrel in hot air convection recurrent state.At cylindrical shell 2 internal thermometers, measure after temperature reaches technological requirement and enter next program.Starting device drive unit 1.After cylindrical shell rotation steadily, start feed conveying device (not shown in FIG.), material is dried by charging aperture 7 access arrangements.Material, under numerous flat oar 32 effects, is done circumference screw around cylindrical shell 2, and is moved to discharging opening 8 directions by charging aperture 7, in moving process, contact with barrel uniformly and form transmission of heat by contact, and moisture in material or solvent are flashed to gaseous state, in cylindrical shell 2 center cohesions.The hot-air at cylindrical shell 2 centers, under the wind speed of circulative convection, becomes heat convection with material shape on the one hand, and the water vapor absorption on the other hand material evaporation being gone out is taken away, and accelerates the transmission of heat by contact process of material, reaches the object of raising the efficiency.When material is under flat oar 32 effects, while moving to cylindrical shell 2 discharge end, through planet drawing mechanism (not illustrating in figure) continuous discharge.As need are controlled dry output and drying effect, the angle of capable of regulating equipment rotating speed peace oar, to reach the object of technology controlling and process.
