Abstract
A kind of laboratory heat preservation filtering crystallization device, including filter cup and crystallization bottle, in crystallization bottle on be communicated with evacuation tube, be equipped with filter plate in cup filtering, filter cup and pass through clamp device and connect crystallization bottle.The utility model will filter cup and crystallization bottle is combined, so that two steps of filtering and crystallization to solution are combined into a progress, avoids loss of the solution frequently in filter device and crystallization device transfer process.
Description
Technical field
The utility model is related to a kind of laboratories to keep the temperature filtering crystallization device.
Background technology
With the stable development of chemical industry, the chemical industry equipment adaptable with it is also in flourishing.Recrystallization be by
Crystal is dissolved in after solvent or melting, the process crystallized from solution or melt again.Recrystallization can make unpurified object
Matter is purified, or the salt mixed is made to be separated from each other.The defect of filtering crystallization device is at present：
（1）The filtering of solution and crystallization are two mutually independent operating procedures, are shifted to crystallization device in filter device
Process filtrate be easy to that solid or spreading is precipitated, cause the loss of product.
（2）It can not be filtered under assigned temperature, the most common filter device in laboratory is generally only used for room temperature mistake
Filter, if it is desired to high temperature filtration, it is necessary to filtering flask and suction funnel are preheating to proper temperature in heater box, and at heat by object
Material filtering just can, this method does not require nothing more than that speed is fast, and very inconvenient for cold winter.
（3）Rapid cooling when in face of the larger liquid of viscosity, being easy later in being filled into filtering flask, viscosity increases, and makes
At the difficult situation of discharging, filter loss is finally caused to cause to calculate error；Sometimes, in order to keep the clarity of product qualified, often
It needs to pad one layer of diatomite in filtering liquid medicine, these operations are extremely difficult in current experimental provision.
Invention content
The technical issues of the utility model solves is to provide a kind of laboratory heat preservation filtering crystallization device, for solving background
Problem in technology.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of laboratory heat preservation filtering crystallization device, including filter cup and crystallization bottle, in crystallization bottle on be communicated with evacuation
Pipe is equipped with filter plate filtering in cup, filter cup and connect crystallization bottle by clamp device.
The clamp device is connecting flange, clip or quick coupling.
Filtering cup and/or crystallization bottle peripheral hardware, there are one chucks, and water inlet pipe and outlet pipe are communicated on chuck.
Agitating device is installed on crystallization bottle, the agitating device includes the casing being connected to crystallization bottle, is set in casing
There are stirring rod, stirring rod to be fixedly connected with the agitating paddle being arranged in crystallization bottle, connect by sealing shroud between casing and stirring rod
It connects.
The sealing shroud includes the rubber sleeve being fixedly connected in casing, and multi-turn lip flange is equipped in rubber sleeve, is stirred
It mixes bar to be located in each circle flange, flange in close proximity is outside stirring rod.
The utility model has the beneficial effects that：
(1) the utility model will filter cup and crystallization bottle is combined, so that two steps of filtering and crystallization to solution
Suddenly it is combined into a progress, avoids loss of the solution frequently in filter device and crystallization device transfer process.
It (2) can be to pouring into cooling into chuck using water inlet pipe and outlet pipe when filtrate carries out crystallization in crystallization bottle
Water enables the quick crystallization of liquid to cool down to the liquid in crystallization bottle.
(3) during the utility model can be covered to filtering cup and crystallization bottle clip synchronize pour into cooling water, so that liquid is filtered
When ensure its constant temperature, make the drug wherein dissolved not filtering when be precipitated, liquid crystallization directly in crystallization bottle, makes it after filtering
Discharging can be facilitated and reduced and calculate error.
（5）The utility model crystallization bottle can carry out program mode crystallization in crystallization according to technological requirement.
（6）Filtering cup and crystallization bottle can split, convenient for being cleaned to filtering cup and crystallization bottle.
