Abstract
The utility model belongs to glass ware, and particularly relates to a flask for distillation. The flask comprises a flask body, a distillation column, and a distillation branch pipe, wherein the distillation column is arranged at the upper part of the flask body and the distillation branch pipe is arranged on the distillation column. The flask is characterized by also comprising a feeding bottle port which is arranged beside the distillation column, and the mouth of the distillation branch pipe is ground. Since the flask body is additionally provided with the feeding bottle port, the feeding part and the distillation part are separated and feeding can be carried out without dismounting a thermometer; the mouth of the distillation branch pipe is ground, the ground mouth is connected with a condenser pipe after being coated with silicone grease, so that the installation is simple and the sealing performance is good. The flask has a simple structure and is convenient to use.
Description
Technical field
The utility model belongs to glassware, relates in particular to a kind of flask.
Background technology
The distillation of liquid or Fractionation Experiment are used by round-bottomed flask and still head or the mode of single use distilling flask is carried out, but all there is certain defective in this dual mode: when round-bottomed flask and still head are used, interface is more, the device poor sealing performance; Traditional distilling flask bifurcations and condenser pipe junction, sealing property also is prone to problem, and distilling flask is by the distillation column liquid feeding, the distillation column upper end needs to install thermometer in the experimentation, if utilize same device repeatedly to distill or fractionation operation, repeated disassembled and assembled thermometer, troublesome poeration.
Chinese patent CN 101306394A provide a kind of globular distillation flask, comprises a globular distillation flask body, and this globular distillation flask body is extended with a distillation column, and described distillation column has a transverse branch, has a lasso in described transverse branch periphery.Ferrule arrangement is so that transverse branch is inserted sleeve and condenser tube is more prone to, sealing property improves, but in use must have lasso, sleeve, condenser tube, distillation column transverse branch to cooperatively interact just can realize, trouble is installed, and solves and utilize same device repeatedly to distill or the loaded down with trivial details problem of liquid feeding during fractionation operation.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of distillation flask, comprise flask body, distillation column, distillation arm, described distillation column is positioned at described flask body top, described distillation arm is positioned on the described distillation column, it is characterized in that: also comprise the charging bottleneck, described charging bottleneck is positioned at described distillation column next door, and the mouth of pipe of described distillation arm adopts the ground structure.
Described charging bottleneck adopts the ground structure.
The beneficial effects of the utility model are: added the charging bottleneck at the flask body, feeding part and distillation fraction are separated, need not dismantle thermometer and can feed in raw material; The mouth of pipe of distillation arm adopts the ground structure, and ground is connected with condenser pipe after smearing silicone grease, and good airproof performance is installed simply.The utility model provides distillation flask a kind of simple in structure, easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Among the figure, 1-flask body, the 2-distillation column, 3-distills arm, 4-charging bottleneck, the 5-mouth of pipe.
Embodiment
As shown in Figure 1, take the water white transparency lamp blown glass as raw material, at the mould blowing flask body 1 of large stove with flask, then weld distillation column 2, charging bottleneck 4 in the shoulder of flask body 1 with the lamp worker, then will distill arm 3 and be welded on the distillation column 2, make this flask.
Make use-case
As shown in Figure 1, this distilling flask is fixed on the iron stand, drag is put into heating jacket, and the distillation column mouth is installed the thermometer with plug, and the mouth of pipe 5 of distillation arm 3 is connected with condenser pipe, the outlet of condenser pipe is connected with fraction collector, the liquid that the needs distillation is processed joins in the flask body 1 by charging bottleneck 4, and charging bottleneck 4 is filled in glass stopper, opens the heating jacket power supply, regulate heating-up temperature, carry out fraction collection.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
Claims (2)
