Description

Medicine vacuum stirring drying machine

The utility model relates to a kind of medicine vacuum stirring drying machine, belongs to dry technical field.

Though the existing now patent No. that meets the GMP code requirement is 98247022.3 medicine filtration drying refiners, and number of patent application is 99225960.6 the dry stirring drier of medicine vacuum filtration, but the diversity of medicine kind and medicine subtractive process, nature also proposes the diversity requirement to the medicine purification apparatus.Just must carry out centrifugal filtration during the medicine that has is refining, but need under the vacuum stirring condition, carry out drying, so do not need to have vacuum filtration, the bifunctional vacuum filtration stirring drier of vacuum stirring drying, and as long as the vacuum stirring drying machine of simple function.At above-mentioned needs, provide a kind of with external force that stir with the medicine vacuum stirring drying machine Low Temperature Steam generator.

The purpose of this utility model is exactly at above-mentioned needs, provide a kind of with external force that stir with the medicine vacuum stirring drying machine Low Temperature Steam generator.

The technical solution of the utility model is: it is by charge door, discharging opening, vacuum pumping opening, heating jacket, the tail gas filtering plate, agitator, interior heating plate, bearing outside, drive sprocket, clean door, rotating shaft, cylindrical shell, the Low Temperature Steam generator, reach formations such as frame, one up and down the side, two ends be equal diameter semicircle cylindrical shell and be fixed on the frame, the tail gas filtering plate is located at the top of the semicircle cylindrical shell in upper end, rotating shaft is the cantilever-shaped bearing outside that passes band inclusion seal and washable axial gap block and enters in the cylindrical shell, the welding fixedly sleeve of agitator is fastened on the rotating shaft with big nut, therefrom the interior heating plate of the polylith of recessing equidistantly is welded on the cylindrical shell bottom vertically on the mind-set, steam condensation water UNICOM mouth is arranged between heating jacket and the interior heating plate, and agitator has radial-axial concurrently and strikes off bur and the axial and radially mixed effect of pusher on the heating surface.The Low Temperature Steam generator is located under the cylindrical shell on the methods, rack, make a thermal source with 0.1～0.2Mpa saturated vapor or electric power, produce 20～95 ℃ of low-temperature saturated steam secondary heat source for heat drying, the steam condensate (SC) that produces after the steam heat release relies on potential difference and gravity to loop back in the Low Temperature Steam generator.Clean and the replacing filter screen for convenient, on cylindrical shell, open Butterworth Hatch and add the flange cover plate with semicircular center, cylindrical shell top and diameter and make to clean door.Enter powder dust between the rotating shaft axial play for cleaning because of respiration, in order to avoid pollute medicine because of respiration spues the residue between axial play during product drying afterwards, establish washable axial gap block in bearing outside one side, wearing and tearing foreign substance pollution medicine for avoiding conventional frictional property sealing gas leakage suck pollution foreign matter and frictional property sealing self to produce is established nothing wearing and tearing inclusion seal at the bearing outside opposite side again.Driving machine and sprocket wheel drive to stir and turn round stirring, promote heat exchange between material and the heating surface.Heating jacket also can directly feed 0.1～0.4MPa saturated vapor, or produces 0.1～0.4MPa saturated vapor with the electric power heating, carries out≤150 ℃ of high-temperature vacuums and stirs drying fast.

The utility model is applicable to the thermal sensitivity product purification drying of various cream pasty states and loose shape, is specially adapted to 20～50 ℃ of high-thermosensitive products drying under vacuum.The utility model structure is fully followed the GMP requirement; the medicine refining quality is guaranteed; owing to adopted inclusion seal; inert gas content is few in the tail gas; very help the organic solvent in the condensation recovery filter cake from tail gas; both help the organic solvent resource recycling and increased economic efficiency, and helped environmental protection.
