Description

Technical Field

[0001] The utility model mainly relates to the technical field of evaporators, in particular to a vertical rotary evaporator. Background Art

[0002] A rotary evaporator, also known as a rotary evaporator, is a commonly used laboratory equipment. It consists of a motor, a distillation flask, a heating pot, a condenser and other parts. It is mainly used for continuous distillation of volatile solvents under reduced pressure conditions. It is used in chemistry, chemical industry, biomedicine and other fields. The rotary evaporator can be used to recover and evaporate organic solvents. It uses a motor to drive the distillation flask to rotate.

[0003] In the prior art, a rotary evaporator is used in a water bath for heating. The liquid in the water bath will evaporate continuously at high temperature. If the liquid is not replenished in time, the height of the liquid will decrease, and the contact area between the liquid and the rotary bottle will decrease, thereby affecting the heating of the rotary bottle by the water bath. In addition, the temperature of the liquid inside the water bath will also decrease if heated for a long time, which will also affect the heating effect of the water bath on the rotary bottle. Utility Model Content

[0004] The technical solution of the present utility model is aimed at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. It mainly provides a vertical rotary evaporator to solve the technical problem proposed in the above background technology that the water level and temperature will drop when the liquid inside the water bath furnace heats the rotating bottle for a long time, which will affect the heating effect of the rotating bottle.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0006] A vertical rotary evaporator comprises a rotary evaporator body, a water bath for containing liquid for heating a rotary bottle is arranged above the rotary evaporator body, a liquid storage tank for storing the heated liquid for standby is arranged above the rotary evaporator body, and a floating assembly for automatically and alternately opening and closing a liquid inlet and a liquid outlet opened on one side of the water bath is arranged inside the water bath.

[0007] Preferably, a connecting pipe is slidably connected to the rotary evaporator body, one end of the connecting pipe is connected to the rotary bottle, and the other end of the connecting pipe is connected to the rotary bottle.

[0008] Preferably, the water bath is detachably mounted above the rotary evaporator body, and the lower side of the rotary bottle is immersed in the liquid inside the water bath.

[0009] Preferably, the liquid storage tank is fixedly installed above the rotary evaporator body, a liquid infusion tube is provided above the liquid storage tank, and a heating rod is provided inside the liquid storage tank.

[0010] Preferably, the liquid storage tank is connected to the water bath furnace via a liquid inlet pipe and a liquid outlet pipe respectively, wherein one end of the liquid inlet pipe connected to the liquid storage tank is tilted upward, and one end of the liquid outlet pipe connected to the liquid storage tank is tilted downward.

[0011] Preferably, the floating assembly includes a baffle and a floating block, the baffle is slidably connected to the inner wall of the water bath furnace, and the floating block is fixedly mounted on one side of the baffle.

[0012] The present invention has the following advantages compared with the prior art: the floating block drives the baffle to float inside the liquid in the water bath. When the liquid in the water bath is in a just right state, the baffle rises to block the liquid inlet of the water bath, the liquid outlet will open, and part of the liquid will be transported into the liquid storage tank through the liquid outlet pipe. When the liquid level drops, the baffle will drop again to block the liquid outlet, the liquid inlet will be opened, and the liquid in the liquid storage tank will be transported into the water bath through the liquid inlet pipe again, and the liquid in the liquid storage tank is heated by the heating rod. In this way, the baffle is continuously moved up and down according to the water level of the liquid to switch the opening and closing of the liquid outlet and the liquid inlet, so that the liquid in the water bath can be kept in one range and the liquid in the water bath can be kept at a high temperature at all times. This not only prevents the water bath from heating the rotating bottle for a long time, which will cause the liquid to evaporate continuously and cause the water level to drop and the water bath to be unable to heat the water bath, but also prevents the temperature of the liquid from gradually decreasing due to long-term heating, resulting in poor heating effect on the rotating bottle.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly used by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention.

[0023] Please refer to the attached Figure 1-Figure 5 A vertical rotary evaporator includes a rotary evaporator body 1, a water bath 2 for holding liquid for heating a rotary bottle 3, a liquid storage tank 4 for storing the heated liquid for standby, and a floating assembly for automatically opening and closing the liquid inlet and liquid outlet on one side of the water bath 2.

[0024] The specific operation process of the present invention is as follows: liquid is injected into the water bath furnace 2 and the liquid storage tank 4, the liquid inside the liquid storage tank 4 is continuously heated, the rotating bottle 3 is lowered, and the lower side of the rotating bottle 3 is immersed in the liquid inside the water bath furnace 2. The rotating bottle 3 continuously rotates and the rotating bottle 3 is continuously heated by the liquid to achieve evaporation. At the same time, when the water level of the liquid inside the water bath furnace 2 is high, the floating component will rise to block the liquid inlet of the water bath furnace 2 and open the liquid outlet. The liquid will be transported into the liquid storage tank 4 through the liquid outlet for heating. As the liquid is transported into the liquid storage tank 4, the liquid level inside the water bath furnace 2 begins to drop, and the floating component will drop along with the water level. The floating component opens the liquid inlet of the water bath furnace 2, and the floating component opens the liquid outlet of the water bath furnace 2. At this time, the liquid inside the water bath furnace 2 will not be transported into the liquid storage tank 4. At this time, the liquid inside the liquid storage tank 4 is transported into the water bath furnace 2 through the liquid inlet, so that the water level of the liquid inside the water bath furnace 2 and the liquid temperature can be kept high at all times.

[0025] Please refer to Figures 1-4 A connecting tube 12 is slidably connected to the rotary evaporator body 1, one end of the connecting tube 12 is connected to the rotary bottle 3, and the other end of the connecting tube 12 is connected to the collecting bottle 11. The water bath furnace 2 can be detachably installed above the rotary evaporator body 1, and the lower side of the rotary bottle 3 is immersed in the liquid inside the water bath furnace 2.

[0026] The rotary evaporator body 1 drives the connecting pipe 12 up and down to drive the rotating bottle 3 to descend and immerse it in the liquid in the water bath furnace 2. Then, the rotating bottle 3 rotates continuously, and the liquid inside the water bath furnace 2 heats the rotating bottle 3, causing the liquid inside the rotating bottle 3 to evaporate and generate steam. The steam is transported to the inside of the collecting bottle 11 through the connecting pipe 12 for collection.

[0027] Please refer to Figure 1-Figure 5 The liquid storage tank 4 is fixedly installed above the rotary evaporator body 1, and a liquid infusion tube 7 is provided above the liquid storage tank 4. A heating rod 8 is provided inside the liquid storage tank 4. The liquid storage tank 4 is connected to the water bath furnace 2 through a liquid inlet pipe 5 and a liquid outlet pipe 6 respectively. The liquid inlet pipe 5 is connected to the liquid storage tank 4 at one end and is tilted upward, and the liquid outlet pipe 6 is connected to the liquid storage tank 4 at one end and is tilted downward. The floating assembly includes a baffle 9 and a floating block 10. The baffle 9 is slidably connected to the inner wall of the water bath furnace 2, and a floating block 10 is fixedly installed on one side of the baffle 9.

[0028] The heating rod 8 is used to heat the liquid inside the liquid storage tank 4. The floating block 10 floats above the liquid inside the water bath furnace 2. When the water level of the liquid inside the water bath furnace 2 is high, the floating block 10 drives the baffle 9 to rise, and the baffle 9 blocks the liquid inlet. At this time, the liquid inside the liquid storage tank 4 cannot be transported into the water bath furnace 2 through the liquid inlet pipe 5. At this time, the lower liquid outlet is in an open state, and the liquid inside the water bath furnace 2 is transported into the liquid outlet pipe 6 through the liquid outlet. The liquid inside the water bath furnace 2 is transported into the liquid outlet pipe 6 and transported into the liquid storage tank 4 for recovery and heating. When the liquid inside the water bath furnace 2 is continuously transported into the liquid storage tank 4, the water level of the liquid inside the water bath furnace 2 begins to drop, and the floating block 10 will drive the baffle 9 to start descending, the baffle 9 will open the liquid inlet and block the liquid outlet. At this time, the liquid inside the water bath furnace 2 cannot be transported into the liquid storage tank 4 through the liquid outlet pipe 6. The liquid inside the liquid storage tank 4 is transported into the water bath furnace 2 through the liquid inlet pipe 5, so that the height of the liquid level inside the water bath furnace 2 and the temperature of the liquid can be maintained.

[0029] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
