Description
Technical Field
The utility model belongs to the technical field of the experimental apparatus, a make things convenient for rotary evaporator of business turn over material is related to.
Background
The rotary evaporator is by the evaporation apparatus of wide application, the volatile solvent of continuous distillation under the mainly used decompression condition, it is rotatory to utilize a motor to drive the distillation flask, because constantly rotatory, liquid attaches to on the wall of distillation apparatus, form the one deck liquid film, the area of evaporation has been increaseed, make the evaporation rate accelerate, volatile solvent collects after the condensation, remaining in the distillation flask is the non-volatile solvent, current rotary evaporator, because the distillation flask need be rotatory through motor control, make its structure complicated, and remaining non-volatile solvent need be demolishd the distillation flask in the distillation flask and just can pour out, cause inconvenience for the operation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that prior art exists, provide a make things convenient for rotary evaporator of business turn over material, the utility model aims to solve the technical problem how to improve the portability of business turn over material.
The purpose of the utility model can be realized by the following technical proposal: a rotary evaporator convenient for feeding and discharging is characterized by comprising a support, a distillation flask, a condenser and a material pipe, wherein the distillation flask is vertically and rotatably connected to the support, a discharge hole is formed in the upper end of the distillation flask, the condenser is connected with the discharge hole through a steam connecting pipe, and a plurality of guide blades are uniformly arranged on the circumferential direction of the inner wall of the upper part of the distillation flask; a water bath kettle positioned below the distillation flask is arranged on the bracket; the material pipe is inserted in the steam connecting pipe and extends to the distillation flask.
Furthermore, the inner wall of the lower part of the distillation flask is provided with a spiral liquid guide strip.
Can send into the retort with mixed solvent through the material pipe in, after accomplishing the distillation, the material of the nonvolatile that remains in the retort also can be taken out through the material pipe, and at this moment, the material pipe needs to be inserted to the retort bottom.
Receive the in-process of water bath at the retort, the material that can volatilize in the retort is the steam condition and passes through the retort top, and through taking over to condenser, steam can order about the mass distribution at the flow in-process evenly, and vertical retort is rotatory, and then make liquid form the liquid film at the retort inner wall, efficiency of volatilizing is improved, and simultaneously, in order to make liquid film distribution area bigger, be provided with spiral helicine drain strip on the inner wall of retort, the retort is at rotatory in-process, even less liquid also can be with great face number cloth at the retort inner wall. The rotary evaporator is suitable for separation and purification of a mixed solvent which is not easy to volatilize or has less volatile substances in the mixed material.

FIG. 1 is a schematic diagram of the structure of the evaporator under distillation and feeding conditions.
FIG. 2 is a schematic view of the evaporator in a discharge state.
In the figure, 1, a distillation flask; 2. a condenser; 3. a material pipe; 4. a steam connecting pipe; 5. a guide vane; 6. a water bath kettle; 7. a liquid guiding strip.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the rotary evaporator convenient for feeding and discharging comprises a support, a distillation flask 1, a condenser 2 and a material pipe 3, wherein the distillation flask 1 is vertically and rotatably connected to the support, the upper end of the distillation flask 1 is provided with a discharge hole, the condenser 2 is connected with the discharge hole through a steam connecting pipe 4, and a plurality of guide blades 5 are uniformly arranged on the inner wall of the upper part of the distillation flask 1 in the circumferential direction; a water bath 6 positioned below the distillation flask 1 is arranged on the bracket; the material pipe 3 is inserted in the steam connecting pipe 4 and extends to the distillation flask 1.
The inner wall of the lower part of the distillation flask 1 is provided with a spiral liquid guide strip 7.
Can send into retort 1 with the mixed solvent through material pipe 3 in, after accomplishing the distillation, the nonvolatile material that remains in retort 1 also can be taken out through material pipe 3, and at this moment, material pipe 3 need insert to retort 1 bottom.
At retort 1 in-process that receives the water bath, but the volatile material in retort 1 is the steam state and passes through retort 1 top, and through taking over to condenser 2, steam can order about the mass distribution evenly at the in-process that flows, and vertical retort 1 is rotatory, and then make liquid form the liquid film at retort 1 inner wall, the efficiency of volatilizing is improved, simultaneously, in order to make liquid film distribution area bigger, be provided with spiral helicine drain strip 7 on retort 1's inner wall, retort 1 is at rotatory in-process, even less liquid also can be in retort 1 inner wall with great face total mark cloth. The rotary evaporator is suitable for separation and purification of a mixed solvent which is not easy to volatilize or has less volatile substances in a mixed material.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions may be made by those skilled in the art to the specific embodiments described without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
