The specific embodiment
A kind of Spiral Draper-type Vaccum Rake Type Drier as shown in Figure 1 has cylindrical shell 1, is provided with end cap 2 at cylindrical shell 1 two ends, and cylindrical shell 1 is fixedlyed connected with the support 3 that is arranged at cylindrical shell 1 bottom; In cylindrical shell 1, be provided with rabbling mechanism; Support 3 is provided with transmission component 4, transmission component 4 and driving rabbling mechanism; Be provided with charge door assembly 5 on the top of cylindrical shell 1, be provided with discharging opening assembly 6, on charge door assembly 5, also be provided with and vacuumize assembly 7 in cylindrical shell 1 bottom; Also be provided with heating chamber 8 and heat-insulation layer 9 in the outside of cylindrical shell 1.
Original rake leaf formula rabbling mechanism structure comprises center rake axle 11, is provided with support arm 15 in center rake axle 11 staggered fixed vertical as shown in Figure 3, is provided with rake leaf 16 in support arm 15 ends, and two support arms 15 of head and the tail are provided with material scraping plate 10.Though the rake leaf 16 at band inclination angle is the circumference linking when work, but because of support arm 15 is to be the cross single-screw to be arranged in center rake axle 11, adjacent rake leaf 16 spacings are bigger, cause to flow regime preferably the concentrate drying of the higher pasty material of fine grained drying and moisture content had drawback.
