Abstract
The invention relates to a rotary drum vacuum dryer, and belongs to the technical field of heat exchange. The rotary drum vacuum dryer is used for vacuum drying of medicaments and chemical products containing organic solvent and used for reclaiming the organic solvents by condensation. The rotary drum vacuum dryer consists of a rotary drum, left and right rotating shafts, a filter plate and the like, wherein a heating jacket is arranged outside the rotary drum, a plurality of inner heating plates are arranged in the rotary drum, and the rotary drum has equal length and diameter; the rotating shafts are positioned in the balance center of the rotary drum, so that the driving power in rotary motion can be lightened; the rotary drum vacuum dryer is provided with a manhole special for quickly and cleanly unloading a material; compared with a double-cone vacuum dryer, the volume of the rotary drum is about 1.5 times that of double cones of the same diameter; the shape of the drum is simple, so that the inner heating plates with simple shape and large area can be arranged in the drum, the F/V value of the heating area F (m<2>) in unit volume V (m<3>) is 3 to 4 times greater than that of the traditional double cones, and the drying efficiency of the dryer is greatly improved; and the rotary drum consists of a straight drum body and a standard end enclosure, so the rotary drum vacuum dryer is simple for machining and favorable for reducing the manufacturing cost.
Description
Technical field
The present invention relates to a kind of rotating cylinder vacuum drier, belong to technical field of heat exchange, comprise medicine and the vacuum drying of chemical products filter cake that contains organic solvent, and organic solvent is reclaimed in condensation for various.
Background technology
Along with the development of medicine and fine chemical product, dry product scale is increasing, and producing needs the big energy-saving drying machine of efficient high yield day by day.The existing bipyramid vacuum drier of popularization and application, though it belongs to the energy-saving drying machine of indirect, because of reasons in structure, the ratio F (m of its unit volume and the heating surface (area) (HS that is contained
2)/V (m
3) very little, and can when equipment amplifies, the enlarged-diameter with bipyramid more be dwindled by F/V value trend.So the drying efficiency of bipyramid vacuum drier is very low, particularly the bipyramid drying efficiency of Da Xinghuaing is lower, force factory to have to adopt the very low fluidized drying that can't reclaim organic solvent of the thermal efficiency or many bipyramid parallel operations, not only waste equipment investment but also influence energy-saving and emission-reduction.
Summary of the invention
The purpose of this invention is to provide a kind of rotating cylinder vacuum drier.Technical scheme of the present invention is: it is by steam condensation water swivel joint, drive sprocket, left-handed rotating shaft, left shaft holder, driving machine, heating jacket, charging manhole, tail gas filtering plate, compositions such as interior heating plate, vacuum exhaust pipe, dextral shaft, right bearing seat, exhaust tube holder, bleeding point.Be characterized in: left and right rotating shaft is established in the both sides, rotating cylinder center of establishing heating plate in the polylith thin type in addition in the saturated vapor heating jacket, left and right rotating shaft is bearing on the left and right bearing block, and driving machine drives the sprocket wheel in the left-handed rotating shaft and promotes the rotating cylinder rotation; The draw ratio of rotating cylinder equates that a manhole is located at the center of an end socket, and another manhole then is located at the corner of another end socket; Be parallel to the maintenance flushing channel that rotating shaft center's line is established width and manhole equal diameters and communicated with manhole in the rotating cylinder, establish the interior heating plate of polylith perpendicular to flushing channel in the flushing channel both sides, heating steam and steam condensation water are by steam condensation water UNICOM mouth UNICOM heating jacket and interior heating plate; Pass dextral shaft by the fixing vacuum exhaust pipe of fixed leg and enter in the rotating cylinder, establish the tail gas filtering plate at slightly upward bent exhaust tube end, the saturated vapor behind the filtering powder dust is extracted out through bleeding point; Add the steam inlet of hot water and steam on the steam condensation water swivel joint and enter heating jacket, coagulate water and then extract out by coagulating water out.
Adopt the equal rotating cylinder of draw ratio and establish the centre of equilibrium of rotating shaft, can alleviate the power that driving machine promotes the rotating cylinder rotation at rotating cylinder.The supercentral manhole of end socket is to clean usefulness for reinforced and equipment, and another can be used for totally drawing off dry products rapidly when rotating cylinder is in 45 ° of inclinations.Interior heating plate is located at the conrotatory veer, helps and the contacting and friction of dried material, and can promote heat exchange and heating plate self-cleaning.
This type drying machine and double-cone dryer compare, and the bipyramid cylindrical shell volume that the rotating cylinder volumetric ratio diameter that draw ratio equates is identical is big by 1.About 5 times, rotating cylinder is made of straight tube and standard sealing head, and the interior heating plate shape in the rotating cylinder is more a lot of greatly than interior heating plate simple shape and area in the bicone, and rotating cylinder not only volume is big, THS is long-pending also much bigger, embodies the F (m of indirect drying equipment drying efficiency
2)/V (m
3) the comparable traditional bipyramid vacuum drier of value is big 3～4 times, and can also reduce the manufacturing cost of equipment.
