Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As Fig. 1, shown in 2, a kind of band cutter double conic rotary vacuum dryer, comprise support 1, transmission device 2, cylindrical shell 3, Bracket setting has left pillar 11, right pillar 12 and base 13, left, be connected and fixed by base 13 between right pillar, cylindrical shell 3 is arranged on left pillar 11 and right pillar 12 by the left main shaft 41 of both sides and right main shaft 42, cylindrical shell 3 two ends install left main shaft 41 and right main shaft 42 respectively, left main shaft 41 and right main shaft 42 are separately positioned on corresponding main shaft bearing, main shaft bearing is arranged on left pillar 11 and right pillar 12, transmission device 2 is arranged on the side of cylindrical shell 3, be connected with the left main shaft 41 of cylindrical shell 3 or right main shaft 42, be connected with right main shaft 42 in the present embodiment, by motor 21, reductor 22, gear wheel 23 forms transmission device 2, gear wheel 23 is connected with right main shaft 42, right main shaft 42 is driven to rotate, thus drive whole cylindrical shell 3 to rotate.
Be provided with cutting tool 7 in cylindrical shell 3, cutting tool 7 connects driving device for cutter 8.As Fig. 5-7, cutting tool 7 is provided with multiple blade, and each blade thick middle, both sides are thin, and blade sections is class prismatic, insert corner arc-shaped transition.In cylindrical shell 3 rotary course, the material of agglomerating caking is constantly smashed by cutting tool 7, cutter rotating speed is very fast, and the steel of cutter is more crisp, easily fracture, therefore thick middle, both sides 71,72 thin is arranged to by blade, and turning 73 arc-shaped transition of blade, such cutter is not allowed easily broken, wear-resisting, durable.Cutting tool 7 has two covers, and be separately positioned on the symmetric position up and down of cylindrical shell 3, better effects if smashed by such material.
Driving device for cutter 8 comprises cutter drive motors 81, cutter drive motors 81 connection conducting device 10, and electric installation 10 is arranged on right main shaft 42, and follows right main shaft 42 synchronous rotary, and electric installation 10 connects power supply.The cutter drive motors of cutting tool 7 needs wire connecting power, because cylindrical shell is in rotary course always, therefore can produce the problem that wire is wound around.The present invention adopts the electric installation 10 of following right spindle synchronous and rotating, electric installation 10 is divided into outer ring and inner ring, outer ring maintains static, and outer ring is connected and fixed power supply by connector lug, and inner ring to be fixed on right main shaft and with main axis, inner ring connector lug connects crushing knife motor, by turning block ring conductive electric current between Internal and external cycle, like this when electric installation follows main shaft rotation, outer ring is motionless, inner ring rotates with spindle synchronous, thus can not produce the problem of wire winding.
As Fig. 4, left main shaft 41 and right main shaft 42 are all hollow spindle, communicate with inner barrel, left main shaft 41 is connected with hot water inlet pipe 51 and hot water out pipe 52, vacuum-pumping tube 61 is provided with in right main shaft 42, vacuum-pumping tube 61 one end is provided with sintered filter stick, is also provided with the anti-blowpipe 62 of blowing for sintered filter stick in right main shaft 42.
As Fig. 3, cylindrical shell 3 is provided with inner bag 31, chuck 32 and lagging casing 33 from inside to outside, is provided with deflector 9 in chuck 32, and hot water inlet pipe 51 and hot water out pipe 52 all communicate with deflector 9, and deflector 9 is spirally wrapped around on inner bag 31.Be provided with in chuck and be spaced apart 300-500mm between two deflectors, 9, two deflectors.Hot water is passed in deflector 9 from hot water inlet pipe 51, and deflector 9 is spirally wrapped around on inner bag 31, and whole inner bag is heated by deflector 9 by such hot water, and the width optimum of deflector 9 is set to 300-500mm, makes whole cylindrical shell homogeneous heating.
When drying machine work, material enters in cylindrical shell by charging aperture, charging aperture is sealed, is then vacuumized in cylindrical shell by vacuum-pumping tube 61, vacuumize rear atmospheric pressure and reduce, moisture just easily evaporation inside material, then pass into heat in deflector 9 from hot water inlet pipe 51, then starting switch drives cylindrical shell 3 to rotate by transmission device 2, drives cutting tool 7 to rotate by driving device for cutter 8, in dry run, the material of agglomerating caking is pulverized again, make dry better effects if; After dry materials completes, hot water is flowed out by hot water out pipe 51, and material by discharging opening 14 out.
Micro mist is easily adsorbed on the surface of vacuum-pumping tube and affects drying time under vacuum conditions in addition, now can blow away by anti-blowpipe 62 pulse backblowing filtrated air or nitrogen the micro mist being adsorbed on vacuum-pumping tube surface, in blowback process, blowback nitrogen is first through the film essence filter core of 0.2 μm, so will not there is the phenomenon of the contaminated material due to blowback.
Barrel designs becomes about 60 ° angles, main purpose be in order to increase heat exchange area and powder in rotation be elliptic motion so not easily balling-up, and powder not easily produces trapping phenomena in discharging process, can ensure disposable material to be put totally.
Inner bag 31, chuck 32 and main shaft sleeve are integrally welded, adopt interference fits between two ends main shaft and main shaft sleeve, and main shaft adopts welded type to be connected with main shaft sleeve again, have welded the main shaft run-out in rear guarantee two ends and have been no more than 0.12---0.18mm.This main shaft and axle sleeve adopt the connected mode of welded type, can ensure that whole cone is bearing in frame and the rigidity of long-term running, to such an extent as to it are water-tight to reach guarantee, gastight requirement.
