Background technology
In the production process of medicine, the medicinal raw material that water content is higher, generally needs powder baking oven to be dried, insert in baking oven, by air blast, to it, advertise hot blast, accelerate moisture evaporation, yet, in air blast process, drive flowing of air, on the one hand, owing to sneaking into oxygen, can make medicine and some metal break flours or impurity generation oxidation reaction, it is polluted, its quality is declined, even affect drug effect; On the other hand, air blast meeting causes the volatilization of medicine powder, causes product to decline; Meanwhile, hot blast flows in baking oven, and at air inlet place, wind-force is excessive, and each region air quantity is uneven, causes the inconsistent phenomenon of medicine degree of drying.
Utility model content
Based on the deficiencies in the prior art, main purpose of the present utility model is to provide the baking oven that a kind of drying effect is even, little to medicine pollution, can improve medicine quality, for heat drying medicine and reagent.
It is a kind of for heating the baking oven of medicine and reagent that the utility model provides, it comprises casing, tubulation interchanger, cold-trap, butterfly valve and heating unit, described tubulation interchanger is built in casing, medicine and reagent is positioned on tubulation interchanger, wherein, described heating unit is communicated with tubulation interchanger by pipeline, and described cold-trap is communicated with casing by valve, by heating unit, tubulation interchanger is carried out to circulating-heating.
Preferably, described baking oven further comprises the vacuum unit being communicated with cold-trap, and vacuum unit vacuumizes casing by cold-trap.
Preferably, described heating unit comprises water heater, water-circulating pump, water inlet pipe and outlet pipe, described water-circulating pump is installed on water inlet pipe, water inlet pipe and the outlet pipe respectively two ends of tubulation interchanger are communicated with, hot water is exported in water heater, through water-circulating pump pressurization, input to the water inlet end of tubulation interchanger, by the water side of tubulation interchanger, exported, flow back in water heater.
Preferably, described cold-trap is connected with casing by dish valve.
Preferably, described tubulation interchanger comprises the some tubulations that are arranged in parallel, and the water inlet end of each tubulation and water side are communicated with water inlet pipe and the outlet pipe of heating unit respectively.
Compared with prior art, of the present utility model for heating the baking oven of medicine and reagent, by heating unit or cold-trap, to the tubulation interchanger in casing, import heating water, while importing heating water, the mode of transmitting by dividing plate heat, so that the moisture in medicine and reagent is therefrom evaporated, and by the mode vacuumizing, it is derived outside casing by cold-trap.By casing is vacuumized, compare with traditional air blast drying mode, under vacuum state, moisture more easily therefrom volatilizees and detaches, and has improved the efficiency of drying, and heating effect is more even, and, under vacuum state, heat the pollution of avoiding impurity it to be caused in medicine and reagent as metal fillings enters, conducting effect is good, has reduced the boiling point of water evaporation, the better effects if of crystallization water volatilization, simultaneously, heat conduction is easy to control, has avoided the oxidation of oxygen to medicine, has improved the quality of medicine.
Accompanying drawing explanation
Fig. 1 is that the utility model is a kind of for heating the structural representation of the baking oven of medicine and reagent.
The specific embodiment
Shown in Fig. 1, it is a kind of for heating the baking oven of medicine and reagent that the utility model provides, it comprises casing 1, tubulation interchanger 2, cold-trap 3, dish valve 4 and heating unit 5, described tubulation interchanger 2 is built in casing 1, medicine and reagent is positioned on tubulation interchanger 2, and wherein, described heating unit 5 is communicated with tubulation interchanger 2 by pipeline, described cold-trap 3 is communicated with casing 1 by dish valve 4, by 5 pairs of tubulation interchangers of heating unit 2, carries out circulating-heating.
The interior parallel of described casing 1 is shown some arrangement pipe interchangers 2, in tubulation interchanger 2, be connected with heat-conducting liquid, as water or conduction oil, each tubulation interchanger 2 is connected with heating unit 5 by pipeline respectively, medicine is accommodated in open-top receptacle, and is arranged on tubulation interchanger 2, and heating unit 5 imports heat-conducting liquid in each tubulation interchanger 2, so that medicine and reagent on tubulation interchanger 2 is heated, by the moisture evaporation in medicine out.
Described baking oven further comprises the vacuum unit 6 being communicated with cold-trap 3, and vacuum unit 6 vacuumizes by 3 pairs of casings 1 of cold-trap.
Described heating unit 5 comprises water heater 50, water-circulating pump 51, water inlet pipe 52 and outlet pipe 53, described water-circulating pump 51 is installed on water inlet pipe 52, the two ends that water inlet pipe 52 and outlet pipe 53 are located at respectively tubulation interchanger 2 are communicated with, hot water is exported in water heater 50, through water-circulating pump 51 pressurizations, input to the water inlet end 52 of tubulation interchanger 2, by water side 53 outputs of tubulation interchanger 2, flow back in water heater 50.The water inlet end of described each tubulation interchanger 2 and water side are communicated with water inlet pipe 52 and the outlet pipe 53 of heating unit 5 respectively.By regulating the water temperature in water heater 50, control the temperature of heat-conducting medium in tubulation interchanger 2, water temperature raises, and in medicine, moisture evaporation is accelerated.The temperature of the heat-conducting medium in water heater 50 is no more than 100 degrees Celsius.
