Description

Technical Field

[0001] The utility model relates to the field of rotary evaporators, in particular to a rotary evaporator with an anti-sputtering structure. Background Art

[0002] Rotary evaporator, also known as rotary evaporator, is a common laboratory equipment, composed of motor, distillation flask, heating pot, condenser and other parts. It is mainly used for continuous distillation of volatile solvents under reduced pressure conditions, and is used in chemistry, chemical industry, biomedicine and other fields. During the distillation process, liquid solvents are prone to sputtering when they are heated and boiled. At the same time, when loading, the solvent may also sputter when it flows into the rotating flask, which can easily lead to impure solvents after distillation and separation, and then lead to deviations in experimental results. Therefore, it is necessary to design a rotary evaporator with an anti-sputtering structure. Utility Model Content

[0008] Furthermore, sealing gaskets are provided at the connection points of various components of the body.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0015] A rotary evaporator with a sputtering protection structure, such as Figure 1-3As shown, it includes a body 1, which includes a feeding part 101, a distillation part 102, a condensation part 103 and a collection part 104. The feeding part 101 includes a feeding pipe 1011 and is controlled by a feeding valve 1012; the condensation part 103 is connected to the collection part 104 through a conduit, and a connecting pipe 1031 is provided below the condensation pipe of the condensation part 103 for the feeding pipe 1011 to pass through; the distillation part 102 includes a rotating mechanism 1023, and a rotating bottle 1022 is connected to the rotating mechanism 1023, and the rotating bottle 1022 is placed in a water bath pot 1021, and the feeding pipe 1011 extends to the rotating bottle 1022. At the bottleneck, a splash-proof ball tube 105 is also connected between the connecting tube 1031 and the rotating mechanism 1023, and a plurality of grooves 1051 and protrusions 1052 are provided on the inner wall of the splash-proof ball tube 105; when in use, the loading valve 1012 on the loading tube 1011 is opened to introduce the solvent into the rotating bottle 1022, the switch of the water bath 1021 is turned on to heat it, and the rotating mechanism 1023 is started at the same time. The rotating mechanism 1023 drives the rotating bottle 1022 to rotate in the water bath 1021. As the temperature rises, the solvent reaches the boiling point and evaporates, and the steam enters the condensation part 103 to cool and then flows into the collection part 104, thereby completing the distillation and separation of the solvent. When the solvent is heated and boiled and splashes, the splashed solvent will enter the splash-proof tube 105 along the conduit. Due to the spherical design of the splash-proof tube 105, the solvent will splash on the inner wall of the splash-proof tube 105. The grooves 1051 and protrusions 1052 on the inner wall of the splash-proof tube 105 help to guide the solvent and prevent it from accumulating on the inner wall of the splash-proof tube 105. The solvent will flow to the bottom of the splash-proof tube 105 under the action of gravity, thereby preventing the liquid solvent from entering the condensation section 103 and causing impure distillation separation. At the same time, during the loading process, if the solvent splashes, the splash-proof tube 105 can also avoid the above-mentioned problem.

[0016] In the utility model, preferably, the bottom of the splash-proof ball tube 105 also has a drain port 1053 and is controlled by a drain valve 1054; when too much solvent is sputtered, the drain valve 1054 can be opened to discharge the solvent in time, which can avoid disassembly of the instrument and facilitate operation.

[0017] In the utility model, preferably, filter screens are provided at the connection points at both ends of the splash-proof ball tube 105, which can filter solid impurities splashed out of the solvent, and the filter screen has a through hole for the feeding tube 1011 to pass through, thereby ensuring that the feeding tube 1011 passes through.

[0018] In the present invention, preferably, sealing gaskets are provided at the connection points of the various components of the main body 1 to ensure sealing.

[0019] The working principle of the utility model is as follows: when in use, the feeding valve 1012 on the feeding tube 1011 is opened to introduce the solvent into the rotating bottle 1022, the switch of the water bath 1021 is turned on to heat it, and the rotating mechanism 1023 is started at the same time. The rotating mechanism 1023 drives the rotating bottle 1022 to rotate in the water bath 1021. As the temperature rises, the solvent reaches the boiling point and evaporates. The steam enters the condensation part 103 to cool and then flows into the collection part 104, thereby completing the distillation and separation of the solvent. When the solvent is heated and boiled and sputters, the sputtered solvent will enter the splash-proof tube 105 along the conduit. Due to the spherical design of the splash-proof tube 105, the solvent will sputter on the inner wall of the splash-proof tube 105. The grooves 1051 and protrusions 1052 on the inner wall of the splash-proof tube 105 help to guide the solvent and prevent it from accumulating on the inner wall of the splash-proof tube 105. The solvent will flow to the bottom of the splash-proof tube 105 under the action of gravity, thereby preventing the liquid solvent from entering the condensation part 103 and causing impure distillation separation; at the same time, during the feeding process, if the solvent sputters, the splash-proof tube 105 can also avoid the above problems. In addition, a drain port 1053 is provided at the bottom of the splash-proof tube 105. When too much solvent is sputtered, the drain valve 1054 can be opened to discharge the solvent in time, which can avoid disassembling the instrument and facilitate operation.
