Description

Technical Field

[0001] This invention relates to the field of rotary evaporator technology, specifically to an intelligent rotary evaporator, its operating method, and its application in the laboratory. Background Technology

[0002] A power amplifier, commonly known as a "loudspeaker amplifier," amplifies weak signals from an audio source or preamplifier to drive speakers. Current technology suffers from numerous interference signals within the various circuit modules of a power amplifier, resulting in poor signal quality between modules. Furthermore, power supply noise significantly impacts audio output; and heat dissipation difficulties in each module not only easily damage circuit components but also contribute to signal distortion.

[0003] Chinese patent application number CN202021467867.5 discloses an intelligent rotary evaporator that solves the problem of the inability to freely adjust the rotation speed of the distillation flask in a rotary evaporator. In use, the air in the negative pressure condenser is drawn away by a vacuum pump, creating a negative pressure condition inside the condenser. Furthermore, because the inner diameter of the receiving pipe is larger than the diameter of the feeding pipe, a gap exists between the walls of the feeding and receiving pipes, further creating a negative pressure condition within the passageway of the feeding pipe, receiving pipe, and distillation flask. Under this negative pressure, the liquid in the feeding pipe is drawn into the receiving pipe and finally flows into the distillation flask. During this process, the rotation speed of the magnetic coupler is adjusted by a speed control knob integrated in the control box, thereby adjusting the rotation speed of the distillation flask to meet the rotation speed requirements of different reactions.

[0004] Chinese patent application number CN202122884551.7 discloses a rotary evaporator, belonging to the field of rotary evaporator technology. The rotary evaporator includes a base, with the rotary evaporator body fixedly connected to the upper end of the base. A sliding sleeve is fixedly connected to the upper end of the base, and a sliding tube is slidably connected to the inner circumference of the sliding sleeve. It also includes multiple buffer mechanisms, each comprising an outer sleeve, an upper sliding plate, a first spring, an inner sleeve, and a shock-absorbing component. The outer sleeve is fixedly connected to the lower end of the base, the upper sliding plate is slidably connected to the inner circumference of the outer sleeve, the upper and lower ends of the first spring are fixedly connected to the upper sliding plate and the base respectively, and the inner sleeve is fixedly connected to the upper end of the upper sliding plate. This buffer mechanism buffers the rotational force of the rotary evaporator, reducing the impact of rotational force on the solvent heating and distillation process, improving the efficiency of heating and distillation, and reducing the waste of time and human resources.

[0005] The above solution may encounter the following problems during use: 1. When heating the substance in the evaporating flask, it is necessary to ensure that the evaporating flask can be immersed in the water in the water bath, and at the same time, the evaporating flask needs to be at a certain angle to prevent the solution in the evaporating flask from flowing out. The above solution only provides the vertical movement of the evaporating flask, but does not solve the problem of adjusting the tilt angle of the evaporating flask.

[0006] 2. After the tilt angle of the evaporating flask is adjusted, the evaporating flask is always rotating. If it is not rotated, the angle of the evaporating flask will change, affecting the evaporation effect of the medicine inside the evaporating flask. In severe cases, a sudden change in the angle of the evaporating flask will cause the medicine inside the evaporating flask to flow out. Summary of the Invention

[0022] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This invention relates to an intelligent rotary evaporator, its operating method, and its application in the laboratory. The evaporator includes a base 1 on which a water bath heating pot 11 is fixed. The bottom of the water bath heating pot 11 has a drain valve 12, and a transparent cover 13 is placed on top of the water bath heating pot 11. The interior of the base 1 mainly houses a PLC control board, heating wire, thermometer, control panel, and adjustment buttons. The heating wire heats the water in the water bath heating pot 11 to boiling, facilitating the heating and evaporation of the substance inside the rotating flask 5 to obtain the desired substance. Simultaneously, the thermometer, in conjunction with the control panel, can monitor the water bath heating in real time. The temperature of the water in the water bath 11 changes, and the control panel can display the temperature readings detected by the thermometer in real time, making it easy to intuitively understand the temperature changes in the water bath heating pot 11. The rotation speed of the rotating component 3 can be adjusted via the PLC controller, control panel, and adjustment buttons. The control panel can also display the rotation speed of the rotating component 3 in real time. The base 1 is an existing device and will not be described in detail here. A lifting adjustment component 2 is fixed on the base 1, and the rotating component 3 is mounted on the lifting adjustment component 2. A rotating bottle 5 is fixed to one end of the rotating component 3. The lifting adjustment component 2 is used to adjust the height and tilt of the rotating bottle 5. The angled design facilitates the immersion of the rotating bottle 5 in the water bath heating pot 11. The rotating assembly 3 is fixedly connected to the rotating bottle 5, allowing it to rotate and thus ensuring uniform heating of the substance within. The other end of the rotating assembly 3 is rotatably connected to a four-way bottle 4. The upper end of the four-way bottle 4 is connected to a condenser 7, and the lower end of the condenser 7 is connected to a collecting bottle 6. The condenser 7 cools the evaporated gas, condensing it into liquid. The condensed liquid flows into the collecting bottle 6 and is collected. A stopcock can be installed at the lower end of the four-way bottle 4, separating the collecting bottle 6 from the entire system, allowing for easy liquid discharge. The entire rotary evaporation system can continue to operate temporarily. After emptying the collection bottle 6, slowly open the stopcock of the four-way bottle 4, and the entire system can continue to operate normally. The four-way bottle 4 is equipped with a feeding pipe 41, which extends into the rotating bottle 5. The feeding pipe 41 can directly inject the substance into the rotating bottle 5. At the same time, a stopcock is set on the feeding pipe 41 to prevent gas from escaping along the feeding pipe 41 during evaporation. The condenser 7 is fixed with a bracket 8, which is fixed on the base 1. The bracket 8 supports and fixes the four-way bottle 4, the collection bottle 6, and the condenser 7 to prevent them from falling and breaking during operation.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 7Considering that the evaporated gas needs to flow smoothly into the condenser 7 and be easily collected, an existing negative pressure device and condensate circulation device are used. The negative pressure device is connected to the negative pressure interface 72, the outlet of the condensate is connected to the inlet 712, and the inlet is connected to the outlet 711. The condenser 7 is equipped with a coil 71 inside. The upper end of the condenser 7 is equipped with the negative pressure interface 72. The upper end of the coil 71 is the outlet 711, and the lower end of the coil 71 is the inlet 712. The negative pressure device mainly consists of a vacuum pump and a gas extraction device. The device consists of a sealing system. Air is drawn out by a vacuum pump to create a negative pressure environment inside the device, which lowers the boiling point of the solution and allows evaporation to start at a lower temperature, avoiding damage to the sample components by high temperature. The condensate circulation device usually includes a low-temperature cooling liquid circulation pump, which can provide low-temperature circulating water or oil bath heating to enhance the condensation effect. The condensate circulation device introduces cold water into the coil 71 from the inlet 712 and flows out from the outlet 711 back into the condensate circulation device to cool the water and ensure the condensation effect of the condenser 7.

[0025] Please see Figure 4 , Figure 5 and Figure 6Considering that when heating the substance in the rotating flask 5, it is necessary to ensure that the rotating flask 5 can be immersed in the water in the water bath heating pot 11, and at the same time, the rotating flask 5 needs to be at a certain angle to prevent the solution in the rotating flask 5 from flowing out, the lifting adjustment component 2 includes a frame 21. Two sliders 22 are slidably connected to the upper and lower ends of the inner side of the frame 21, respectively. A baffle and a protrusion are fixed on the frame 21 for the sliders 22 to slide. The baffle and the protrusion limit the sliders 22, so that the sliders 22 can only move between the baffle and the protrusion. The slider 22 slides within the frame 21, with guide rods 23 and threaded rods 24 on each side. The upper and lower sliders 22 correspond one-to-one. The guide rods 23 are connected to the sliders 22 at their respective ends. The threaded rods 24 are located between the two guide rods 23. The slider 22 slides within the frame 21, allowing the fixed rod 25 to tilt normally. The adjusting block 251 is slidably connected to the guide rods 23, which guide the adjusting block 251 left and right, allowing it to move... The rotating assembly 3 is connected to the two threaded rods 24 by a fixed rod 25. The threaded rods 24 are rotatably connected to the slider 22. An adjusting block 251 is connected to the threaded rods 24. The two ends of the fixed rod 25 are hinged to the adjusting block 251. The adjusting block 251 is slidably connected to the guide rod 23. The fixed rod 25 is fixedly connected to the rotating assembly 3 and is used to adjust the angle and height of the rotating assembly 3. The adjusting block 251 is engaged with the threaded rod 24. Rotating the two different threaded rods 24 can control the two adjusting blocks 251 to move up or down. While the adjusting block 251 moves up and down, since the length of the fixed rod 25 is fixed, the slider 22 will slide during the tilting process of the fixed rod 25. At the same time, since the fixed rod 25 is hinged to the adjusting block 251, the height of the adjusting block 251 can be adjusted by twisting the threaded rod 24, thereby adjusting the tilt angle of the adjusting block 251. This achieves the adjustment of the tilt angle of the rotating assembly 3, ensuring that the rotating bottle 5 is immersed in the water in the water bath heating pot 11 at a certain angle.

[0026] See also Figure 4 , Figure 5 and Figure 6The threaded rod 24 is equipped with a worm gear 27, and there is a gap between the worm gear 27 and the threaded rod 24. When adjusting the tilt angle of the rotating assembly 3, the worm gear 27 and the threaded rod 24 do not drive each other. At the same time, since the worm gear 27 meshes with the synchronous worm 26, the worm gear 27 rotates as the slider 22 moves, while the synchronous worm 26 does not move. The frame 21 is equipped with a synchronous worm 26 that is drivenly connected to the worm gear 27. The slide groove 241 is rotatably connected to the upper slider 22. The upper four corners of the frame 21 are fixed with columns 211, and movable plates 214 are slidably connected to the columns 211. The upper end of the columns 211 is fixed with a top plate 212. The movable plate 214 is embedded with a magnet 2141. When adjusting the tilt angle of the rotating bottle 5, the movable plate 214 is attracted and fixed to the top plate 212 by the magnet 2141. To prevent the worm gear 27 from transmitting power to the threaded rod 24, when adjusting the height of the rotating bottle 5, the movable plate 214 is pushed down, and the magnet 2141 causes the movable plate 214 to be attracted to the vertical frame 21, thereby causing the rubber cone 28 to engage with the threaded rod 24 and the worm gear 27, thus connecting the threaded rod 24 and the worm gear 27. The rubber cone 28 is engaged with the movable plate 214, and the rubber cone 28 is sleeved on the threaded rod 24 and slidably connected to the threaded rod 24. After the rubber cone 28 moves down and engages with the gap between the worm gear 27 and the threaded rod 24, it connects the threaded rod 24 and the worm gear 27, thereby realizing transmission. When the synchronous worm 26 is twisted, the worm gear 27 is driven to rotate, and the rotation of the worm gear 27 drives the threaded rod 24 to rotate. After the threaded rod 24 rotates, it drives the adjusting block 251 to rotate. By changing the direction of rotation of the synchronous worm 26, the adjusting block 251 can be controlled to move up or down, thereby adjusting the height of the rotating bottle 5.

[0027] See also Figure 4 , Figure 5 and Figure 6Considering that after adjusting the tilt angle of the rotating bottle 5, to prevent changes in the angle of the rotating bottle 5, it is necessary to limit it. Multiple grooves 241 are formed along the circumference of the threaded rod 24. The inner arm of the rubber cone 28 has protrusions corresponding to the grooves 241. The lower end of the rubber cone 28 is conical. Angle adjustment knobs 213 are fixed to the upper end of the threaded rod 24. A synchronization knob 261 is fixed to the synchronizing worm gear 26. By forming grooves 241 on the threaded rod 24 and providing protrusions corresponding to the grooves 241 inside the rubber cone 28, when the worm gear 27 drives the threaded rod 24 through the rubber cone 28, it prevents the rubber cone 28 from rotating on the threaded rod 24, thus preventing normal transmission. Simultaneously, the grooves 241... 41 serves as a guide, allowing the rubber cone 28 to slide smoothly on the threaded rod 24. The lower end of the rubber cone 28 is conical, ensuring it accurately enters the gap between the worm gear 27 and the threaded rod 24, where it is inserted and tightened, thus enabling transmission between the worm gear 27 and the threaded rod 24. Furthermore, due to the self-locking function of the worm gear 27 and the synchronous worm 26, if the gap between the two threaded rods 24 needs adjustment after the height of the rotating bottle 5 is adjusted, the worm gear 27 will rotate. Since the synchronous worm 26 is rotatably connected to the vertical frame 21, the worm gear 27 will lock into place, thus achieving a fixing function and preventing changes in the tilt angle of the rotating bottle 5.

[0028] See also Figure 1 , Figure 8 and Figure 9To ensure uniform heating of the substance in the rotating bottle 5, it is necessary to rotate the rotating bottle 5. The rotating assembly 3 includes a protective shell 31 and a fixed platform 37. The fixed platform 37 is fixed to the U-shaped frame 32, and the protective shell 31 is fixed to the fixed platform 37. A rotating cylinder 33 is rotatably connected to the U-shaped frame 32. A fixed knob 34 is provided on the rotating cylinder 33. A first bevel gear 35 is fixed on the rotating cylinder 33. A motor 36 is fixed on the fixed platform 37. A second bevel gear 38 is fixed to the output end of the motor 36. The second bevel gear 38 is drivingly connected to the first bevel gear 35. The rotating cylinder 33 includes left and right pipes, which are rotatably connected and sealed. The fixed knob 34 is provided with... The motor 36 is placed on the left pipe and is used to connect the four-way bottle 4. The connection between the motor 36 and the four-way bottle 4 is sealed. The left pipe is fixedly connected to the U-shaped frame 32. The first bevel gear 35 is fixed on the right pipe. The right pipe is rotatably connected to the fixed knob 34. The right pipe is connected to the rotating bottle 5 and the connection between the right pipe and the rotating bottle 5 is sealed. At the same time, the second bevel gear 38 meshes with the first bevel gear 35. The motor 36 drives the second bevel gear 38 to rotate. At the same time, the force is transmitted to the right pipe through the transmission action of the first bevel gear 35, causing the right pipe to rotate, which in turn causes the rotating bottle 5 to rotate, so that the substance in the rotating bottle 5 is heated evenly. A protective shell 31 is fixed on the motor 36 to prevent the operator from accidentally touching the motor 36 and getting injured.

[0029] This device works in conjunction with existing negative pressure devices and condensate circulation devices. The rotating bottle 5 is mounted and fixed on the rotating drum 33. Water is added to the water bath heating pot 11. The tilt angle of the fixing rod 25 is adjusted by turning different angle adjustment knobs 213. After the angle adjustment is complete, the movable plate 214 is pressed down to allow the rubber cone 28 to engage and insert between the worm gear 27 and the threaded rod 24. The synchronization knob 261 is turned to adjust the base 1, allowing it to move up and down. This controls the downward movement of the rotating assembly 3, causing the rotating bottle 5 to tilt and enter the water bath heating pot 11, ensuring that the bottom surface of the rotating bottle 5 is lower than the top surface of the water bath heating pot 11. The four-way bottle 4 is rotatably connected to the rotating drum 33. The feeding pipe 41 is fixed to the four-way bottle 4 and passes through the rotating drum 33 into the rotating bottle 5. The condenser 7 is fixed to the upper end of the four-way bottle 4, and the collection bottle 6 is fixed to the lower end of the four-way bottle 4. A support 8 is also installed. The four-way bottle 4, collection bottle 6, and condenser 7 are fixed. The negative pressure device is connected to the negative pressure interface 72. The outlet of the condensate is connected to the inlet 712, and the inlet is connected to the outlet 711. The substance to be evaporated is added to the rotating bottle 5 through the feeding pipe 41. The water bath heating pot 11, rotating component 3, negative pressure device, and condensate circulation device can be started for use. First, turn on the negative pressure device. After the vacuum degree is stable, start the rotating component 3 and water bath heating pot 11 for heating to prevent the rotating bottle 5 from falling off or the liquid from being sucked back. After the liquid evaporates, it enters the condenser 7 through the four-way bottle 4 and undergoes heat exchange through the coil 71 to condense the liquid vapor. The condensed liquid drips into the collection bottle 6 for collection. The condensate in the coil 71 circulates. After use, the negative pressure device must be turned off first, and then the heating and rotating component 3 must be turned off to avoid damage to the equipment due to pressure changes.
