Description

Vacuum drying machine of internal heating vibration type

The utility model relates to the swing vacuum drier of a kind of interior heating, belongs to the heat exchange field, is applicable to and must strictness prevents contaminated medicine particle drying, the various crystallizations or the laxity dry materials that also are suitable for hating oxygen, are afraid of to be subjected to crowded wiping or have thermal sensitivity.

Present many medicine particles still adopt hot-air oven, operating condition is poor, the difficult cleanliness factor requirement that meets pharmaceutical production, rate of drying is slow, especially to making the medicine particle that wetting agent is produced to spill essence, in the hot-air oven drying, wine can't be reclaimed, not only dangerous but also wasted resource, to product with thermal sensitivity when adopting disc type hot-air oven or bipyramid rotary formula vacuum drier to carry out drying, all use the hot water that is lower than 100 ℃ to make thermal source, its common drawback is to utilize hot water sensible heat heating and to certainly exist out temperature poor, actual heating-up temperature is the mean value of out temperature, so the heat drying weak effect, the disc type baking oven easily produces foreign matter and enters product, bipyramid rotary formula vacuum drier external jacket heating surface (area) (HS seldom, the ratio of its large-scale heating surface (area) (HS with volume seemed still less so drying machine efficient is very low, steam pipe and the vacuum exhaust pipe because of bipyramid rotary formula vacuum drier all must pass through swivel joint again, so easily produce evaporating, emitting, dripping or leaking of liquid or gas, increase the maintaining workload.

The purpose of this utility model is the shortcoming that overcomes in the prior art medicine drying, and the efficient that can improve heated drying is provided, and improves and spills the smart equal solvent rate of recovery, can prevent evaporating, emitting, dripping or leaking of liquid or gas again, carries out the interior swing vacuum drier of 35～150 ° of wide temperature ranges.

The technical solution of the utility model is the improvement of doing on the bipyramid rotary dryer basis, it comprises exhaust tube, last strip mounting cover, filter, top cover, chuck, discharge port, the condensate pipe stuffing-box, the steam pipe stuffing-box, heating plate, cone, charge door, frame and buncher, reductor, limit switch etc., it is characterized in that in approaching square bicone, longitudinally being equipped with the polylith heating plate of equidistant arrangement, the cone middle part is provided with waves axle, the thermal source steam mouth of pipe and vacuum pumping opening are all near waving axle, pick out by flexible pipe, condensation-water drain is located at cone chuck bottom and is also picked out by flexible pipe, adopting steam (gas) is thermal source, can attach the low-temperature steam heat source generator.Its dry operation principle is as follows: the steam in the heating plate is introduced steam in the chuck by the steam cross over pipe top cover of strap clamp cover, enter heating plate then, condensed water in the heating plate flows directly into chuck, the top cover of strap clamp cover also be heating plate by the dress port lid, and heating plate played fixation, except that steam branch pipe and condensed water arm, leave 50～100mm gap between each heating plate and cone, move usefulness for dried material, utilize limit switch and the ahead running switch variable-speed motor is opened and closed and turns to, drive the axle that waves that is contained in the cone center through reductor again, cone is waved, amplitude is 45 °～70 °, frequency is 6～60 times/hour, waving axle can extend, and makes it pass partition wall cone and actuating unit are separated, to meet the production hygienic practice.

The utility model embodiment is described further in conjunction with the accompanying drawings.

Fig. 1 is the swing vacuum drier structure chart of interior heating;

Fig. 2 is the heating plate layout drawing;

Fig. 3 arranges and the rack construction schematic diagram for importing and exporting pipe;

Fig. 4 waves ± 60 ° of state diagrams for cone.

By Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises exhaust tube 1, last bar mounting cover 2, filter 3, top cover 4, steam pipe stuffing-box 5, heating plate 8, cone 9, chuck 10, discharge port 12, condensate pipe stuffing-box 13, charge door 15, frame 24 and buncher, reductor, limit switch is formed, longitudinally insert equidistant row polylith heating plate in the cone 9, present embodiment is with 6, be equipped with one and wave axle 18 at the symmetrical centre place of cone 9, the thermal source steam mouth of pipe and vacuum pumping opening are all near waving axle 18, pick out by the steam hose 22 and the flexible pipe 21 of bleeding, condensation-water drain is located at cone chuck 10 bottoms and is picked out by flexible pipe 23, cone 9 tops of strap clamp cover 10 have slot for heating plate 8 usefulness are installed, heating plate 8 is anchored on sealing in the stuffing-

box

5 and 13 of top cover 4 and cone 9 by steam branch pipe 9 and condensed water arm 11, cone 9 and top cover 4 all are equipped with chuck, the chuck 10 of the chuck of top cover 4 and cone 9 is by steam cross over pipe 14 UNICOMs, strip mounting cover 2 and 19 is specialized in to install when circle is filled out in sealing and is used, and heating plate 8 is welded by two-layer thin plate and reinforcing prop 7.Present embodiment with spacing open and the ahead running switch variable-speed motor is opened and closed and turns to, waving axle through the decelerator drive more back and forth waves the cone work for 45 °～70 °, Fig. 4 is that expression cone 9 is made ± 60 ° of states when waving, it is thermal source that present embodiment adopts steam (gas), subsidiary Low Temperature Steam heat source generator can carry out 35 °～150 ℃ heat dryings that temperature range is wide.

Because the utility model adopts cone to wave, the turnover mouth of pipe is near balance staff and adopt flexible pipe to pick out, the sealed letter sealing, thereby this drying is superior more than former drying machine, this drying machine waves slowly, squeeze during material rolls and wipe slightly, medicine particle is reduced pulverize, this drying machine can be realized maximizing, along with volume enlarges, the exaggerated scale of heating surface (area) (HS is bigger, because main heating surface (area) (HS all is embedded in the material, so radiation loss reduces half than conventional double conic rotary vacuum dryer, owing to utilize steam latent heat, temperature unanimity on each hot spot, so rate of drying is fast, the drying machine inner surface carries out polishing does not have the dead angle, and it is convenient to clean, the cancellation swivel joint, reduce evaporating, emitting, dripping or leaking of liquid or gas, alleviate maintaining work, have to utilize and improve operating environment, be particularly conducive to the minimizing inert gas and enter vacuum system, improve the alcohol equal solvent rate of recovery.
