Abstract

The invention relates to a non-sealing single-cone vacuum dryer, which belongs to the technical field of heat exchange and used for drying medicaments in vacuum mode. The vacuum dryer is formed by a single-cone drum, a heating clamping sleeve, an inner heating plate, a filter, a left (right) rotation shaft, a steam heating coil, a driving machine and the like. The single-cone drum is formed by an oval sealing head and an inclined abnormal shaped cone and used for both quickly discharging materials and increasing the volume and the area of the heating plate, two ends of the heating plate are well stressed oval sealing heads, and the heating clamping sleeve also serves as a low temperature evaporation generator to produce saturation steam in a temperature from 30 DEG C to 100 DEG C. In the structure, sealing pieces capable of causing abrasion to foreign matters and polluting the medicaments are removed to ensure the quality of drying products. The whole heating area of the dryer is 2 to 4 times that of a conical body, and the vacuum dryer can reduce temperature and drying temperature difference for high-degree thermal sensitivity medicaments. The vacuum dryer can conduct 30 DEG C low temperature heating drying, enables some medicaments to change from freeze dryer drying into dyer drying, thereby greatly reducing energy consumption and saving drying cost.

Description

There is not the single awl of sealing vacuum drier

Technical field

The present invention relates to the single awl of a kind of nothing sealing vacuum drier, belong to technical field of heat exchange, supply the medicine vacuum drying to use.

Background technology

Be provided with the rotation vacuum seal between the Rotating Double cone of traditional bipyramid vacuum drier of popularization and application and the stationary vacuum exhaust tube at present; Because rotating seal is in the abominable condition of work of dry friction, encapsulant can wear and tear surely in friction over a long time and produce to wear and tear and pollute foreign matter in the seal.Be under the vacuumizing condition, polluting foreign matter can only be sucked in the bicone by negative pressure, pollutes the medicine in the drying, has had a strong impact on the quality of medicine.Particularly to directly removing the powder-injection of packing powder pin after some dryings, so the pollutant meeting vein obstruction fine vascular and the cerebrovascular are the harmfulness especially severe.Even many non-powder-injection medicines, harmfulness can not looked.In the existing annual hundreds of thousands time adverse drug reaction, the adverse drug reaction that is caused by the structural pollution hidden danger of bipyramid vacuum drier must occupy certain ratio.

Summary of the invention

The purpose of this invention is to provide the single awl of a kind of nothing sealing vacuum drier; Spin friction formula vacuum seal is not established in the space that in single conic tube, links with dry medicine; Thereby rooted out the structural pollution hidden danger of traditional bipyramid vacuum drier, guaranteed the not pollution of frayed foreign matter of dry medicine.Technical scheme of the present invention is: do not have the single awl of sealing vacuum drier by driving machine, left shaft holder, drive sprocket, steam inlet, steam condensation water movable joint, coagulate water out, middle bearing bracket, left-handed rotating shaft, heating jacket, single conic tube, interior heating plate, charge door, discharge port, filter, dextral shaft, right bearing seat, vacuum exhaust pipe and tail gas outlet etc. and form.Be characterized in: single conic tube is that the ellipsoidal head other end is then for constituting to the oblique abnormity awl two parts of a lateral deviation by an end; The heating jacket two ends constitute for ellipsoidal head entirely; Establish polylith and the perpendicular interior heating plate of rotation in single conic tube, the left rotation and right rotation axle is fixed on cylindrical shell spin balancing center, left rotation and right rotation axle and with 15～18 ° of inclinations; Guarantee that the capacity of the filling material that rolled at 50% o'clock does not cover the bottom of filter; Left-handed rotating shaft is bearing on left shaft holder and the middle bearing bracket, and dextral shaft is bearing on the right bearing seat, and driving machine drives that drive sprocket promotes 360 ° of rotations of single conic tube in the left-handed rotating shaft; Establish width and equal to add (unloading) material mouthful (manhole) diameter being parallel to rotating shaft center's line; And add (unloading) material with two and mouthful connect the back and make the passage that maintenance is cleaned; Interior heating plate flat raft is perpendicular to the both sides of flushing channel; Steam with coagulate the steam condensation water UNICOM mouth and heating jacket perforation of water through interior heating plate two ends, and be weldingly fixed on single conic tube through steam condensation water UNICOM mouth; Filter edge is enclosed within on the dextral shaft and with rotating shaft and rotates synchronously, and the stationary vacuum exhaust tube inserts in the dextral shaft, and the tail gas after filter filters is from tail gas outlet extraction; Heating steam and steam condensation water are through steam inlet on the steam condensation water movable joint in the left-handed rotating shaft and the steam(-)coil that coagulates in the water out importing heating jacket; Pure water in the heating evaporation heating jacket produces 30～100 ℃ saturated vapor, is made for the dry thermal source of indirect.

Do not have sealing single awl vacuum drier and traditional bipyramid vacuum drier relatively,, guarantee outside the dried drug quality, under same inner barrel diameter condition, can establish more bigger interior heating plates except eradicating seal configuration contact scar hidden danger.F (the m of the heating surface (area) (HS (F) that is had because of unit volume (V) ²)/V (m ³) value; Comparable traditional bipyramid vacuum drier is big 2～4 times, and promptly 2～4 times of drying efficiencies that does not have the single awl of a sealing vacuum drier are to the traditional double vacuum drier, and one is supported 2～4; Can save 1/2～2/3 power consumption; Bigger advantage is because F/V value enlarges significantly, can satisfy under low heating-up temperature difference condition height thermal sensitivity product is carried out～30 ℃ low temperature rapid draing, directly substitute freeze drying inevitable in operating～30 ℃ heat drying process; Can not substitute freeze drying by there being the single awl of sealing vacuum drier thereby created, for saving energy consumption significantly and equipment investment provides condition.
