Description

Technical Field

[0001] The utility model relates to the technical field of rotary evaporation instruments, in particular to a rotary evaporation anti-splash ball. Background Art

[0002] In laboratories, a splash guard is often installed between the condensation area and the rotary evaporator to prevent splashing caused by boiling during the rotary evaporation process. In a typical splash guard, the inner tube connecting to the rotary evaporator is sealed at the top and has holes on the side to divert the liquid.

[0003] The liquid that enters the anti-splash ball will not automatically flow back to the rotary evaporator. This is because the inner tube of the anti-splash ball is not perpendicular to the horizontal plane during use, resulting in a height difference between the bottom of the anti-splash ball and the inner tube. Even if a reflux hole is set below the anti-splash tube, the liquid at the bottom of the anti-splash ball will not flow back to the rotary evaporator.

[0004] Therefore, it is particularly important to propose a rotary evaporation splash-proof ball that can enable the liquid at the bottom of the splash-proof ball to flow back to the rotary evaporation bottle during the rotary evaporation process. Utility Model Content

[0005] In order to overcome the defects of the prior art, the utility model proposes a rotary evaporation splash-proof ball, which can make the liquid at the bottom of the splash-proof ball flow back to the rotary evaporation bottle during the rotary evaporation process.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] The utility model provides a rotary evaporation splash-proof ball, comprising a splash-proof cavity with a cavity, an air inlet, an air outlet and a spiral surface; the air inlet and the air outlet are respectively arranged on both sides of the outer wall of the splash-proof cavity, and the air inlet and the air outlet are respectively connected to the interior of the splash-proof cavity; the spiral surface is arranged in the splash-proof cavity, the outer edge of the spiral surface is connected to the inner wall of the splash-proof cavity, the spiral surface and the inner wall of the splash-proof cavity form a spiral channel, and the spiral channel takes the air inlet as the starting point; the terminal outlet of the spiral channel is arranged on the inner wall of the splash-proof cavity.

[0008] The rotary evaporation splash-proof ball according to the embodiment of the utility model has at least the following beneficial effects: by arranging the splash-proof tube in the form of a spiral channel along the inner wall of the splash-proof ball, the liquid in the splash-proof ball can be driven to flow back to the rotary evaporation bottle along the spiral channel while the rotary evaporation splash-proof ball rotates. The design of the spiral water wheel is combined with the rotary evaporation bottle to achieve the purpose of guiding the liquid in the splash-proof ball to flow back to the rotary evaporation bottle without disassembling the splash-proof ball during the rotary evaporation process.

[0009] According to some embodiments of the present invention, the shape of the splash-proof cavity includes at least one of a sphere, an ellipsoid, and an oval.

[0010] According to some embodiments of the present invention, the air inlet and the air outlet are respectively arranged on both sides of the outer wall of the splash-proof cavity in the direction of the central axis.

[0011] According to some embodiments of the present invention, the spiral surface is a helicoid, and the spiral surface includes at least one of a regular helicoid, an oblique helicoid (Archimedes helicoid), a sincos helicoid, and an involute helicoid.

[0012] It should be noted that a helicoid is a curved surface formed by a variable-length generatrix performing helical motion (constant rotation and axial movement) around an axis. The path formed by the helical motion at the end of the generatrix closest to the axis is called the inner edge, while the path formed by the helical motion at the end of the generatrix further from the axis is called the outer edge. The angle between the generatrix and the inner wall of the splash guard chamber, facing the air inlet, can also be referred to as the angle between that segment of the helicoid and the inner wall of the splash guard chamber.

[0013] It should be noted that the rotation direction of the spiral surface can be left-handed or right-handed, without specific limitation. The technicians in this field can choose according to the rotation direction of the specific rotary evaporator. Generally, a right-handed spiral surface corresponds to a right-handed rotary evaporator.

[0014] According to some embodiments of the present invention, the angle between the spiral surface and the inner wall of the splash-proof cavity toward the air inlet is less than 90°; preferably, the angle between the spiral surface and the inner wall of the splash-proof cavity toward the air inlet is less than 60°.

[0015] According to some embodiments of the present invention, one end of the generatrix of the helical surface falls on the axis of the helical motion, or the generatrix of the helical surface intersects the axis of the helical motion. This arrangement ensures that the spiral channel is a spiral pipe, preventing liquid from directly splashing onto the air outlet, while also enhancing the effect of guiding liquid backflow.

[0016] According to some embodiments of the present invention, the rotation angle of the generatrix spiral motion of the helical surface is 360° to 1080°; preferably, the rotation angle of the generatrix spiral motion of the helical surface is 360° to 720°.

[0017] According to some embodiments of the present invention, the spiral surface blocks the space between the air inlet and the air outlet, so that the air inlet and the air outlet cannot be vertically connected.

[0018] According to some embodiments of the present invention, the spiral channel is a spiral pipe.

The angle formed between the direction of the terminal outlet and the direction of the air outlet can be an angle between skew lines or a plane angle.

[0022] In a second aspect, another technical solution provided by the present invention is: a rotary evaporator comprising any of the above-mentioned rotary evaporation splash-proof balls.

[0023] Beneficial effects of the utility model:

[0024] The utility model proposes a rotary evaporation splash-proof ball. By arranging a splash-proof tube in the form of a spiral channel along the inner wall of the splash-proof ball, the liquid in the splash-proof ball can be driven to flow back to the rotary evaporation bottle along the spiral channel while the rotary evaporation splash-proof ball rotates, thereby achieving the purpose of guiding the liquid in the splash-proof ball to flow back to the rotary evaporation bottle without disassembling the splash-proof ball during the rotary evaporation process.
