Abstract
The utility model discloses a condensing backflow dispenser which comprises a condensing medium flow pipe, a steam lifting pipe, a backflow pipe, a discharging hole and a grinding hole; the steam lifting pipe is arranged in the condensing medium flow pipe; the opening of the steam lifting pipe is upward; the grinding hole is arranged at the lower end of the steam lifting pipe; the backflow pipe is connected to one side of the steam lifting pipe; and the discharging hole is connected to the other side of the steam lifting pipe. The condensing backflow dispenser disclosed by the utility model is capable of effectively preventing a backflow liquid from being contacted with lift steam, integrates condensation, backflow and solvent collection into a whole, and has the advantages of being simple in structure, convenient for use and controllable in backflow and solvent extraction speed.
Description
Technical field
The utility model relates to a kind of condensation reflux unit, is specifically related to a kind of condensing reflux knockout for recrystallization.
Background technology
The recrystallization method of purification is one of the most frequently used method of organic reaction separating solids crude product, and its principle is to utilize the difference of the solubility of each component in certain solvent in the mixture, and different component is separated.The recrystallization method of purification generally comprise choice of Solvent, hot saturated solution preparation, remove impurity with heat filtering, crystal are separated out, six steps such as detection of the collection of crystal and washing drying, crystal purity; When the preparation of hot saturated solution, need use condensation reflux unit, common condensation reflux unit equipment complexity, the difficulty that refluxes, and the extraction inconvenience of excessive solvent.
The utility model content
The utility model purpose: the purpose of this utility model is in order to solve deficiency of the prior art, to provide a kind of simple in structure, easy to use, and backflow and the controlled condensing reflux knockout of solvent rate of withdrawal.
Technical scheme: a kind of condensing reflux knockout described in the utility model, comprise the cooling medium flow duct, steam riser, return duct, drain hole and ground, be provided with the steam riser in the described cooling medium flow duct, described steam riser opening up, described steam riser lower end is provided with ground, one side of described steam riser is connected with return duct, and the opposite side of described steam riser is connected with drain hole.
As optimization, the height of described return duct is greater than the height of drain hole.
As optimization, be respectively equipped with flow control valve on described return duct and the drain hole.
As optimization, the afterbody of described return duct is " Z " type structure, can effectively avoid withdrawing fluid to contact with rising steam.
Beneficial effect: the utility model can effectively avoid withdrawing fluid to contact with rising steam, and this device collection condensation, backflow, solvent collection and one are simple in structure, easy to use, and backflow and solvent rate of withdrawal are controlled.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
A kind of condensing reflux knockout as shown in Figure 1, comprise cooling medium flow duct 1, steam riser 2, return duct 4, drain hole 5 and ground 6, be provided with steam riser 2 in the cooling medium flow duct 1, steam riser 2 openings up, steam riser 2 lower ends are provided with ground 6, one side of steam riser 2 is connected with return duct 4, the opposite side of steam riser 2 is connected with drain hole 5, wherein the height of return duct 4 is respectively equipped with flow control valve 3 greater than the height of drain hole 5 on return duct 4 and the drain hole 5, and the afterbody of return duct 4 is " Z " type structure.
The cooling medium flow duct is of a size of Φ 40 * 50, and the high 200mm of steam riser is spaced apart 5mm between steam riser and the cooling medium flow duct, or amplifies in proportion, and the return duct position is higher than drain hole 20mm, or amplifies in proportion; Return duct diameter 6mm, drain hole diameter 6mm.
The course of work of the present utility model is: the lower end of steam riser is connected with flask, opens cooling water, cooling water goes out above advancing from below, requires control cooling water flow velocity according to condensation, guarantees all condensations of steam of coming out from riser; Open reflux tube valve, close the drain hole control valve, heating, solute all dissolving is opened drain hole after beginning to reflux, and collects excessive solvent, closes drain hole when treating just to have solute to separate out, solution in the flask is hot saturated solution, next step operation that can be used for being recrystallized at this moment.
