Abstract
The utility model provides a double tapered rotary vacuum drier which comprises a double tapered rotary tank body, a transmission mechanism, a machine frame, a vacuum filter head, a vacuumizing pipe, a condenser, a buffering tank and a vacuum pump. The condenser comprises an inner tube and an outer tube, the inner tube and the outer tube are both bent in a U shape, the inner tube is sleeved with the outer tube, the inner tube is a cooling water channel, an interlay between the inner tube and the outer tube is a solvent gas channel, the lowermost point of the arc-shaped portion of the lower end of the outer tube is provided with a condensate discharge tube, the condensate discharge tube is connected with a condensate storage tank, solvent gas exhausted from the vacuumizing pipe sequentially passes through a valve I, the condenser solvent gas channel, the buffering tank and the vacuum pump, and the vacuum filter head is arranged at the inlet end of the vacuumizing pipe and located on the upper portion of the tank body. The condenser is additionally arranged so as to recycle solvents, and environment is prevented from being polluted.
Description
technical field
The utility model relates to medicine intermediate technical field of drying, is specifically related to double conic rotary vacuum dryer.
background technology
Double conic rotary vacuum dryer is mainly comprised of biconial rotary tank, transmission mechanism, frame, vacuum filtration head, vacuum-pumping tube, surge tank and vavuum pump, and vacuum-pumping tube, surge tank and vavuum pump are connected by pipeline.In tank body under vacuum state, to chuck, pass into heat carrier heating tank body, wet stock in indirect tank body, in tank body, wet stock vaporize and is dried under vacuum condition, and solvent gas is taken away by vavuum pump after by vacuum-pumping tube, directly enters atmosphere, contaminated environment.In addition, the porous cylindrical shell that existing vacuum filtration head is overcoat filter bag, effective filtration area is little, has limited the raising of vacuum suction amount, the lifting of restriction rate of drying.
summary of the invention
The technical problems to be solved in the utility model is to provide a kind of double conic rotary vacuum dryer, and it realizes solvent recovery.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of double conic rotary vacuum dryer, comprise biconial rotary tank, transmission mechanism, frame, vacuum filtration head, vacuum-pumping tube, condenser, surge tank and vavuum pump, condenser comprises the crooked inner and outer tubes that all take the shape of the letter U, inner tube is enclosed within outer tube, inner tube is cooling water runner, interlayer between inner and outer tubes is solvent gas runner, outer tube lower end curved portions minimum point arranges condensate drain, condensate drain is connected with condensate liquid storage tank, vacuum-pumping tube solvent gas is out in turn via valve I, condenser solvent gas runner, surge tank and vavuum pump, vacuum filtration head is installed in vacuum-pumping tube entrance point and is positioned at tank body top.
Above-mentioned double conic rotary vacuum dryer, in condenser, cooling water and solvent gas countercurrent flow.
Above-mentioned double conic rotary vacuum dryer, vacuum filtration head is sintering polytetrafluoroethylene ripple chimney filter.
Preferably, the length of sintering polytetrafluoroethylene ripple chimney filter is 20-30cm.
Above-mentioned double conic rotary vacuum dryer, connects nitrogen anti-blowpipe on the vacuum-pumping tube of valve I upstream, and nitrogen anti-blowpipe is connected with nitrogen pot, and valve II is set on nitrogen anti-blowpipe.
Above-mentioned double conic rotary vacuum dryer, connects clean water inlet pipe on the vacuum-pumping tube of valve I upstream, and clean water inlet pipe is connected with clean water tank, and valve III and water pump are set on clean water inlet pipe.
Vacuum-pumping tube solvent gas and cooling water out carries out heat exchange in condenser, and solvent gas is met condensation and formed solvent liquid, and condensate liquid enters condensate liquid storage tank stores by condensate drain, sets up condenser, can reclaim solvent, avoids contaminated environment.Solvent is substantially without intermediate pump, avoided adhering to solvent on the flow passage components of vavuum pump, reduced the maintenance of vavuum pump.
accompanying drawing explanation
Below in conjunction with accompanying drawing to further detailed explanation of the utility model:
Fig. 1 is structural representation of the present utility model.
In figure: 1 vacuum filtration head, 2 vacuum-pumping tubes, 3 biconial rotary tanks, 4 condensate liquid storage tanks, 5 condensers, 6 surge tanks, 7 vavuum pumps, 8 nitrogen pots.
