Abstract
The utility model discloses a ceclor acylation kettle which comprises a kettle body provided with a jacket, a stirring device and a power transmission mechanism used for driving the stirring device to move; a cavity is internally provided with cooling coils used for cooling material in the cavity; and the cooling medium leading-in end of the cooling coil extends out of a kettle cover. The ceclor acylation kettle is characterized in that the kettle is provided with two cooling coils. The ceclor acylation kettle has high temperature control accuracy, easily preserves heat, and does not cause partial over-cooling.
Description
Technical field
The utility model belongs to the reaction vessel technical field, is specifically related to a kind of cephalo acylation reaction still.
Background technology
Reactor is very extensive in the application of industries such as food, medicine, chemical industry, and people also are not strange to its structure, comprises kettle, the agitating device that has chuck and is used to order about the power set that agitating device moves.Chinese patent 200820035678.3 discloses a kind of reactor, it comprises that one has the kettle of cavity volume, one is fixed on being used for the kettle cover to the sealing of the open topped position of described cavity volume on the kettle, at least one agitating device and that the material to cavity volume stirs of being used for that is configured on the kettle cover similarly is located at being used on the kettle cover and orders about the power drive mechanism of described agitating device work, be provided with a cooling coil that is used for the material cooling of cavity volume in the described cavity volume, the cold moving medium leading-in end of this cold Moving plate pipe leans out kettle cover and the cooling medium source links, and the cooling medium exit of cooling coil after leaning out kettle cover be installed with medium shower on the kettle outer wall and link and communicate, on the medium shower between cloth be useful on the spray apertures of the medium injection in the medium shower to the outer wall of kettle.Cephalo acylation reaction still; this equipment is striven cephalo-type medicine intermediate acylation reaction is designed; because of the demand of this step reaction pair temperature is a ladder; be respectively-15 ℃ ,-28 ℃ ,-35 ℃, temperature difference precision ± 1 ℃, general producer is direct logical cooled with liquid nitrogen in still; but because the difficult control of the feeding amount of liquid nitrogen; temperature difference precision is difficult to reach, and is difficult for insulation, and can causes local overcooling.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of accuracy of temperature control height, easily insulation are provided, and can not cause the cephalo acylation reaction still of local overcooling.
For achieving the above object; the utility model adopts following technical scheme: cephalo acylation reaction still; comprise kettle, the agitating device that has chuck and be used to order about the power drive mechanism that agitating device moves; be provided with a cooling coil that is used for the material cooling of cavity volume in the described cavity volume; the cold moving medium leading-in end of this cold Moving plate pipe leans out kettle cover, it is characterized in that: described cooling coil is two.
Described kettle is for dividing body structure, and described two cooling coils are the staggered setting of spiraling.
Described kettle is for dividing body structure, and described two cooling coils are the suit setting, and the cooling coil that described disk track is little is arranged in the disk track of another cooling coil.
Extend dog-house on the described kettle cover, be furnished with seal cover on the dog-house.
Described cooling medium is a liquid nitrogen.
The beneficial effects of the utility model are: owing to be provided with cooling coil in the cavity volume of kettle, directly the material in the cavity volume is cooled off by cooling coil, adopt the outer refrigerant circulation of reaction liquid cooling :-15 ℃ of stages of reaction feed to chuck--40 ℃ of degree refrigerant circulation coolings;-28 ℃ of stages of reaction feed to chuck and one group of coil pipe--40 ℃ of degree refrigerant circulation coolings;-35 ℃ of stages of reaction feed to chuck and two groups of coil pipes--40 ℃ of degree refrigerant circulation coolings, and the difficult control of feeding amount that has solved liquid nitrogen, temperature difference precision is difficult to reach, and is difficult for insulation, and can cause the technical problem of local overcooling; Simultaneously coil pipe the flow regime that has changed liquid is set, reduce whirlpool, strengthened stirring intensity, improved the thermal efficiency.
