Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary evaporator accessories, and in particular to a splash-proof ball with liquid adding and draining functions. Background Technology
[0002] In laboratory organic solvent processing, rotary evaporators are often used to evaporate and recover organic solvents. A rotary evaporator consists of a motor, an evaporation flask, a heating pan, a receiving flask, a splash guard, and a condenser. The evaporation flask contains the rotary liquid to be processed. The motor drives the evaporation flask to rotate, so that the rotary liquid is heated evenly to facilitate evaporation. The evaporated solvent vapor is liquefied after passing through the condenser and is collected in the receiving flask. The splash guard serves two purposes: firstly, it connects the rotary evaporator shaft to the evaporation flask; secondly, it intercepts the rotary liquid during the solvent evaporation process, preventing it from boiling over and splashing directly into the receiving flask; and thirdly, it collects the condensate, preventing the condensate from flowing back into the rotary evaporation flask.
[0003] However, as Figure 1 As shown in the diagram, this is a schematic diagram of a conventional anti-splash ball. It can be seen that when the anti-splash ball is installed between the rotary evaporator shaft and the evaporation flask, it is a completely sealed structure. This means that when replenishing the evaporation flask, the anti-splash ball must be removed, which is cumbersome and inconvenient. In addition, as the rotary evaporation continues, the amount of condensate collected inside the anti-splash ball increases. If there is too much condensate, it will flow back into the rotary evaporation flask. Therefore, the entire rotary evaporation system needs to be disassembled to remove the anti-splash ball and drain the condensate collected inside, which brings inconvenience to the continuous rotary evaporation treatment of large amounts of liquid. Utility Model Content
[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a splash-proof ball with liquid addition and drainage functions to facilitate the rotary evaporation of large quantities of rotary evaporating liquid.
[0005] A splash-proof ball with liquid filling and draining functions includes a hollow sphere, a frosted interface I and a frosted interface II fixed on the hollow sphere; the splash-proof ball further includes:
[0006] A double-hole tube, which is fixed to the frosted interface II and extends into the hollow sphere;
[0007] The sample dispensing tube is fixed to the frosted interface II; and
[0008] The drain pipe is fixed to the hollow sphere.
[0009] The aforementioned anti-splash ball has both liquid addition and drainage functions. It does not need to be disassembled during actual rotary evaporation operations and is suitable for continuous rotary evaporation, providing convenience for the rotary evaporation of large quantities of liquid.
[0010] As a further improvement to the above solution, the frosted interface I and frosted interface II are arranged on the corresponding two walls of the hollow sphere. In this utility model, the frosted interface I2 is internally frosted to facilitate a sealed connection with the rotating shaft of the rotary evaporator, while the frosted interface II3 is inserted into the mouth of the evaporation flask, based on an externally frosted design to achieve a sealed connection.
[0011] As a further improvement to the above solution, the horizontal axis centers of the frosted interface I and frosted interface II, as well as the center of the hollow sphere, are all located on the same horizontal line. The splash-proof sphere of this invention is made entirely of high borosilicate glass, making it heat-resistant and durable.
[0012] As a further improvement to the above scheme, the sample tube has its inlet end passing through the corresponding side wall of the ground sand interface II, and its outlet end located inside the ground sand interface II.
[0013] As a further improvement to the above solution, the inlet end of the sample tube is equipped with valve I, and a flexible tube is connected to the inlet of the sample tube.
[0014] As a further improvement to the above solution, the drain pipe is located below the abrasive interface II, and the drain pipe outlet end is equipped with valve II.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the structure has been optimized, so that the anti-splash ball has the functions of adding and draining liquid. Thus, without disassembling the anti-splash ball, the evaporating liquid can be conveniently added to the evaporation flask and the condensate can be conveniently drained. In actual rotary evaporation operation, there is no need to disassemble the anti-splash ball, which is more suitable for continuous rotary evaporation and provides convenience for the rotary evaporation of large amounts of rotary evaporating liquid.

[0022] The above description of the main component symbols, together with the accompanying drawings and specific embodiments, provides a further detailed explanation of this utility model. Detailed Implementation
[0023] The specific embodiments of this utility model are described in detail below.
[0024] Please see Figure 2 This embodiment provides a splash-proof ball with liquid addition and drainage functions, which includes a hollow ball 1, a frosted interface I2 and a frosted interface II3 fixed on the hollow ball 1, a double-hole tube 4 fixed to the frosted interface II3 and extending into the hollow ball 1, a sample addition tube 5 fixed on the frosted interface II3, and a drainage tube 6 fixed on the hollow ball 1.
[0025] The anti-splash ball in this embodiment is made of high borosilicate glass, which makes it resistant to high temperatures and durable. The anti-splash ball is installed between the rotating shaft of the rotary evaporator and the evaporation flask. When in use, the anti-splash ball is installed at an angle, with the side where the frosted interface II3 connected to the evaporation flask is tilted downward and the side where the frosted interface I2 connected to the rotating shaft is tilted upward.
[0026] The frosted interfaces I2 and II3 are located on the corresponding two walls of the hollow sphere 1, and the horizontal center of the frosted interfaces I2 and II3, as well as the center of the hollow sphere 1, are all on the same horizontal line. In this embodiment, the frosted interface I2 is internally frosted to facilitate a sealed connection with the rotating shaft of the rotary evaporator, while the frosted interface II3 is inserted into the mouth of the evaporation flask, with an externally frosted design to achieve a sealed connection.
[0027] The sample dispensing tube 5 has its inlet end passing through the corresponding side wall of the frosted interface II3, and its outlet end located inside the frosted interface II3. A valve I is installed at the inlet end of the sample dispensing tube 5, and a flexible tube is connected to the inlet of the sample dispensing tube 5. The drain pipe 6 is located below the frosted interface II3, and a valve II is installed at the outlet end of the drain pipe 6.
[0028] Please refer to the following: Figure 3 In this embodiment, the sample addition tube 5 is connected to the evaporation flask. When it is necessary to add rotary evaporating liquid, it is not necessary to disassemble the rotary evaporation flask. Simply stop the rotation, insert the tubing into the liquid to be added, and then open valve I. Under the negative pressure of the rotary evaporation system, the rotary evaporating liquid is forced into the rotary evaporation flask along the sample addition tube 5 to add liquid, so as to facilitate continuous rotary evaporation.
[0029] Please continue reading. Figure 4 During continuous rotary evaporation, condensate will accumulate in the hollow sphere 1 as the evaporation time increases. If condensate accumulation is found during the rotary evaporation process, it is not necessary to disassemble the anti-splash sphere. Simply stop the rotary evaporator and depressurize it, then open valve II, and the condensate can be discharged along the drain pipe 6.
[0030] In summary, the anti-splash ball of this embodiment has the following advantages: the structure has been optimized, enabling the anti-splash ball to have both liquid addition and drainage functions. Thus, without disassembling the anti-splash ball, it is convenient to replenish the evaporating liquid to the evaporating flask and convenient to drain the condensate (the condensate is the solvent vapor liquefied under the action of the condenser tube). The anti-splash ball of this embodiment does not need to be disassembled during actual rotary evaporation operations, making it more suitable for continuous rotary evaporation and providing convenience for the rotary evaporation of large quantities of rotary evaporating liquid.
