Description
Technical field
The utility model is related to medicine intermediate preparation facilities fields, and in particular to a kind of 2- mercaptopyridines preparation facilities.
Background technology
When preparing 2- mercaptopyridines, need to use distillation reactor, however distillation reactor in the prior art into
When row preparation manipulation, find to have the disadvantages that：（1）It is to be heated in bottom mostly, causes heating in kettle uneven；（2）Due to
Reaction kettle is mostly closed structure, and cleaning is inconvenient, makes troubles to operation, and reaction kettle does not wash clean clearly, can be made to result yet
At influence.
Utility model content
To solve the above problems, the utility model provides a kind of 2- mercaptopyridines preparation facilities.
To achieve the above object, the utility model adopts the following technical solution：
A kind of 2- mercaptopyridines preparation facilities, including reaction kettle, cleaning device and distilling apparatus, the interior setting of the reaction kettle
It includes stirring rod and spiral shape agitating fins to have agitating device, the agitating device, and electrical heating is provided in the agitating fins
Device may be implemented to be evenly heated material in reactor by the way that heating device is arranged in spiral shape agitating fins；It is described
Cleaning device includes the annular cleaning pipe being arranged in reaction kettle inner top, and nozzle, the ring are provided in the annular cleaning pipe
The water inlet of shape cleaning pipe is connect with overheat water storage tank and deionized water storage tank respectively by pipeline, and water inlet is stored up with superheated water
It is both provided with valve on pipeline between tank and deionized water storage tank, when needing to clean reaction kettle, first opened hot water storage tank
On valve, so that superheated water is entered annular cleaning pipe under the action of water pump, be then ejected into reaction kettle from nozzle, to reaction
Kettle different location is cleaned, and after cleaning up, then the valve on deionized water storage tank is opened, with deionized water to reaction kettle
Further rinsed；The distilling apparatus includes condenser pipe and collector；Steam (vapor) outlet on the reaction kettle passes through pipe
Road is connect with condenser pipe.
Preferably, be additionally provided with feeding device on the reaction kettle, the discharge port of the feeding device by pipeline with
Charge door on reaction kettle connects, and flow pump is provided on the pipeline between the feeding device and charge door, can adjust and add
The speed of material.
Preferably, the nozzle is rotary nozzle, the cleaning to each position of reaction kettle may be implemented.
Preferably, being provided with transparent observation window on the reaction kettle, the situation in kettle can be observed at any time.
Preferably, being provided with return duct on the reaction kettle, cooling jacket is provided on the return duct, it can be achieved that cold
But.
Preferably, being provided with cold plate in connecting tube between the condenser pipe and steam (vapor) outlet, steam can be risen
To the effect of baffling.
Preferably, being provided with spiral condenser coil in the condenser pipe, the contact area with steam can be increased,
Condensation effect is more preferable.
It can be seen that the preparation facilities of 2- mercaptopyridines described in the utility model in spiral shape agitating fins by setting
Heating device is set, may be implemented to be evenly heated material in reactor；And it is additionally provided with cleaning device, it can not open
Easily reaction kettle is cleaned in the case of reaction kettle, cleaning performance is good.There are substantive distinguishing features compared with prior art
And progress, beneficial effects of its implementation are also obvious.
