Abstract
The utility model is a kind of condenser defrosting device for triple exchange type freeze dryers, and condenser comprises cold-trap, condenser coil and heat exchanger plate, and heat exchanger plate is placed in cold-trap, and condenser coil connects heat exchanger plate, and stretches out from the front end of cold-trap; Defrosting device comprises: enter steam pipe, heat medium pipe; Entering steam pipe extends in cold-trap, steam is incorporated into the frosting position of heat exchanger plate, heat medium pipe and heat exchanger plate internal communication also comprise heating agent entrance, heating agent collector tube and heating agent outlet, by heating agent entrance, outlet is connected heat medium pump with heating agent, so that heat medium circulation brings heat the frosting position of heat exchanger plate from inside.The utility model is circulated and heat is brought to the frosting position of heat exchanger plate from inside by heat medium, in condenser, pass into steam simultaneously, steam directly contacts frosting position, adopt like this steam defrost and heating agent defrost just to reach inside and outside defrost simultaneously simultaneously, thereby can greatly improve the efficiency of defrost and save steam.
Description
Technical field
The utility model relates to pharmacy freeze dryer, relates to specifically a kind of condenser defrosting device of pharmacy freeze dryer.
Background technology
Freeze dryer is widely used in pharmaceutical field, and common pharmacy freeze dryer is triple exchange type freeze dryers.After the freeze-drying operation of pharmacy finishes, meeting frosting in the condenser of freeze dryer, often needs to carry out defrost by foreign medium.Current defrost mode normally adopts steam defrost, and the efficiency of this single steam defrost mode is lower, makes the operating efficiency of pharmacy freeze dryer not ideal enough.
Summary of the invention
The purpose of this utility model is to provide a kind of defrosting device with high defrost efficiency, can greatly improve the defrost speed of condenser, so that freeze dryer can move efficiently.
For achieving the above object, the utility model provides a kind of condenser defrosting device for triple exchange type freeze dryers, and described condenser comprises cold-trap, condenser coil and heat exchanger plate, and heat exchanger plate is placed in cold-trap, condenser coil connects heat exchanger plate, and stretches out from the front end of cold-trap; Defrosting device comprises: enter steam pipe, heat medium pipe; Entering steam pipe extends in cold-trap, steam is incorporated into the frosting position of heat exchanger plate, heat medium pipe and heat exchanger plate internal communication also comprise heating agent entrance, heating agent collector tube and heating agent outlet, by heating agent entrance, outlet is connected heat medium pump with heating agent, so that heat medium circulation brings heat the frosting position of heat exchanger plate from inside.
Heat exchanger plate top in cold-trap is provided with deflector, to guide flowing of steam.
Heat medium is silicone oil, by being squeezed in heat medium pipe by heat medium pump after electrical heating.
The discharge outlet place of condenser is provided with temperature sensor, is preferably thermocouple.
The utility model is circulated and heat is brought to the frosting position of heat exchanger plate from inside by heat medium, in condenser, pass into steam simultaneously, steam directly contacts frosting position, adopt like this steam defrost and heating agent defrost just to reach inside and outside defrost simultaneously simultaneously, thereby can greatly improve the efficiency of defrost and save steam.Temperature sensor is equipped with at condenser discharge outlet place, can, by detecting the temperature of discharge outlet, judge the effect of defrost.
Brief description of the drawings
Fig. 1 is the arrangement figure of the condenser defrosting device for triple exchange type freeze dryers of an embodiment of the utility model;
Fig. 2 is the left view of Fig. 1; And
Fig. 3 is the heat medium pipe structural plan in Fig. 1 embodiment.
Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.First it should be noted that, the utility model is not limited to following detailed description of the invention, the spirit that those skilled in the art should embody from following embodiment is understood the utility model, and each technical term can be done the most wide in range understanding based on Spirit Essence of the present utility model.Identical Reference numeral represents identical part in the accompanying drawings.
The condenser defrosting device for triple exchange type freeze dryers of an embodiment of the utility model as shown in Figure 1 to Figure 3, as shown in the figure, condenser comprises cold-trap 1, condenser coil 3 and heat exchanger plate 2, Fig. 2 illustrates 4 heat exchanger plates, be fixed into an assembly by fixed head, the whole assembly of heat exchanger plate is placed in cold-trap 1, and condenser coil 3 connects heat exchanger plate 2, and stretches out from the front end of cold-trap 1.Defrosting device comprises: enter steam pipe 9, heat medium pipe 8.Enter steam pipe 9 and extend in cold-trap 1, steam is incorporated into the frosting position of heat exchanger plate 2.The internal communication of heat medium pipe 3 and heat exchanger plate 2 also comprises heating agent entrance 6, heating agent collector tube 11 and heating agent outlet 7 (seeing Fig. 1 and Fig. 3), be connected heat medium pump (not shown) by entrance 6 with outlet 7, so that heat medium circulation brings heat the frosting position of heat exchanger plate 2 from inside.On heat exchanger plate in cold-trap 1,2 are provided with deflector 5, to guide flowing of steam.Preferably, heat medium adopts silicone oil, by being squeezed into and carried out heat medium circulation in heat medium pipe 3 by heat medium pump after electrical heating.The discharge outlet (bottom of cold-trap 1, as Fig. 2) of condenser locates to be provided with temperature sensor 10, is preferably thermocouple, pops one's head in as water temperature.
The device of above-described embodiment of the present utility model is arranged in condenser, by means of triple heat exchanger plates 2, silicone oil after heating imports triple heat exchanger plates by heating agent entrance 6, transfers heat to frosting position, then is discharged and formed a heating agent circulatory system by heating agent outlet; Steam enters condenser by steam inlet, transfers heat to equally frosting position.So just reach inside and outside while defrost.Meanwhile, thermocouple temperature probe 10 is equipped with at condenser discharge outlet place, by detecting the temperature of discharge outlet, judges the effect of defrost.
Should be understood that those skilled in the art can make various changes or modifications the utility model after having read above-mentioned instruction content of the present utility model, these equivalent form of values fall within the application's appended claims limited range equally.
