Abstract
The utility model provides a crude active pharmaceutical ingredient and a drying system for an intermediate. The drying system comprises a drying kettle and a heat supply water tank, wherein the heat supply water tank comprises a tank body, a water outlet is formed in the upper portion of the tank body, a water inlet is formed in the lower portion of the tank body, and a heating device is arranged in the tank body. The drying kettle comprises a kettle body and a kettle cover, wherein the kettle body is composed of an outer layer kettle wall and an inner layer kettle wall, a heating cavity is formed between the outer layer kettle wall and the inner layer kettle wall, a hot water inlet which is communicated with the heating cavity is formed in a side portion of the outer layer kettle wall, a hot water outlet which is communicated with the heating cavity is formed in the upper portion of the outer layer kettle wall, the hot water inlet is communicated with the water outlet of the tank body through a water inlet pipeline, the hot water outlet is communicated with the water inlet of the tank body through a return pipe, and a circulating water pump is arranged on the water inlet pipeline. The drying kettle is large in body size, can dry more crude active pharmaceutical ingredients at a time, and is convenient to operate and high in work efficiency, meanwhile, hot water is conveyed to the heating cavity of the kettle body through the heat supply water tank, therefore, the temperature inside the kettle is uniform, and the drying effect is good.
Description
Technical field
The utility model relates to a kind of drying system, particularly the drying system of a kind of bulk drug and intermediate.
Background technology
Existing bulk drug and intermediate drying adopt bipyramid rotary dryer often, and the material ratio that the volume of bipyramid rotary dryer is little, primary drying can fill is less, and operation inconvenience, so production efficiency is low, and production cost is higher.Bipyramid rotary dryer needs revolution in dry run, and therefore power consumption is higher.To drying machine, provide the medium of heat drying a lot, so system very complex, maintenance difficult easily damaged.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and bulk drug a kind of reasonable in design, easy to use and the drying system of intermediate are provided.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is the drying system of a kind of bulk drug and intermediate, be characterized in: comprise drying kettle and heat supply water tank, described supplying hot water case comprises casing, the top of casing is provided with delivery port, the bottom of casing is provided with water inlet, is provided with heater in casing, described drying kettle is provided with kettle and kettle cover, the bottom of kettle is provided with vacuum orifice, the top of kettle is provided with evacuation port, evacuation port is provided with exhaust-valve, described kettle is comprised of outer still wall and internal layer still wall, be set to heated chamber between outer still wall and internal layer still wall, the sidepiece of outer still wall is provided with the hot water inlet be communicated with heated chamber, the top of outer still wall is provided with the hot water outlet be communicated with heated chamber, between hot water inlet and casing delivery port, by inlet pipeline, be communicated with, between hot water outlet and casing water inlet, by water return pipeline, be communicated with, be provided with water circulating pump on inlet pipeline.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the bottom in kettle is provided with the raw material delivery track.
Technical problem to be solved in the utility model can also further realize by following technical scheme, is enclosed with heat-insulation layer on casing, prevents the dissipation of heat in casing.
Technical problem to be solved in the utility model can also further realize by following technical scheme, casing is provided with self-circulation system, self-circulation system comprises the circulating outlet that is located at lower box and the circulation water inlet on casing top, be provided with circulating line between circulating outlet and circulation water inlet, water pump is housed on circulating line, can makes the temperature of the levels water in casing even.
Compared with prior art, the drying kettle kettle volume that the utility model adopts is large, and the raw material of primary drying is more, easy to operate, high efficiency, the heated chamber delivering hot water to kettle by the heat supply water tank simultaneously, make temperature in the kettle even, drying effect is good, and production cost is low.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross section structure schematic diagram of drying kettle.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
With reference to accompanying drawing 1 and Fig. 2, the drying system of a kind of bulk drug and intermediate, comprise drying kettle and heat supply water tank, described supplying hot water case comprises casing 11, be enclosed with heat-insulation layer on casing 11, the top of casing 11 is provided with delivery port, and the bottom of casing 11 is provided with water inlet, is provided with heater 13 in casing 11.
Drying kettle comprises kettle 1 and kettle cover 7, and the bottom of kettle 1 is provided with vacuum orifice 4, on vacuum orifice 4, is connected with vavuum pump, for vacuumizing from bottom to kettle 1, if vacuumize from top, has solvent and drips to material as water refluxes, and material is polluted.The top of kettle 1 is provided with evacuation port 8, on evacuation port 8, exhaust-valve is housed.Described kettle 1 is comprised of outer still wall and internal layer still wall, be set to heated chamber 2 between outer still wall and internal layer still wall, the sidepiece of outer still wall is provided with the hot water inlet 5 be communicated with heated chamber 2, the top of outer still wall is provided with the hot water outlet 6 be communicated with heated chamber 2, heat medium enters heated chamber 2 from hot water inlet 5, from hot water outlet 6, go out, circulation makes the temperature constant in heated chamber 2 like this, thereby makes the temperature in kettle 1 even.Bottom in kettle 1 is provided with raw material delivery track 3, and the dolly that facilitates the workman that raw material will be housed advances in drying kettle by raw material delivery track 3.
