Obviously, the described embodiment is a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figures 1 to 6The utility model provides a technical scheme: a rotary evaporation device, including rotary connection subassembly 1 and heating bath pot 3, rotary connection subassembly 1 includes shell 101, and the top and bottom surface coaxially of shell 101 is provided with extension hole, and the extension hole is provided with connecting pipe 102, and one end of connecting pipe 102 is connected with heating bottle 4, and heating bottle 4 part is located in the inside of heating bath pot 3, and the other end of connecting pipe 102 is rotatably and detachably connected with one end of communicating sleeve 103, and communicating sleeve 103 is fixedly connected with the top surface of shell 101 through support 104, and the other end of communicating sleeve 103 is connected with condensation collection subassembly 5, and the bottom inner wall of shell 101 is rotatably connected with annular turntable 105 arranged coaxially with the extension hole, and annular turntable 105 is connected with driving device through transmission mechanism, and the upper surface both sides of annular turntable 105 are symmetrically provided with installation sliding slot 109, and one end of adjusting slide rod 110 is slidably connected in each installation sliding slot 109, and the other end of two adjusting slide rods 110 is oppositely arranged and is fixedly connected with corresponding arc clamping block 111 respectively, and one side of the upper surface of annular turntable 105 is provided with spacing adjusting mechanism and is connected with two adjusting slide rods 110, and shell 101 is installed on lifting support 2.

[0026] Need to explain, when connecting, heating bottle 4 port sets outer thread, and the corresponding port of connecting pipe 102 sets inner thread, and the both are screwed tightly, and can be separated when disassembling, and the other end of connecting pipe 102 and one end of communicating sleeve 103 are connected and rotatably connected through the structure of swivel joint, and can also be disassembled. The swivel joint has a sealing ring inside to ensure the sealing of the connecting part, and its connection mode is: one end of the swivel joint is connected with the connecting pipe 102 through thread or clamp, and the other end is connected with the communicating sleeve 103 in a similar way, and when disassembling is needed, the connecting parts can be loosened. The other end of the communicating sleeve 103 and the condensation collection subassembly 5 are connected through thread connection and other ways, which can be connected and disassembled. The condensation collection subassembly 5 includes a condenser tube and a collection bottle, and one end of the condenser tube is connected with the communicating sleeve 103 through thread connection. The condenser tube is provided with a cooling liquid inlet and outlet, and an external cooling liquid circulating device is connected to make the cooling liquid circulate in the condenser tube to cool the evaporated gas. The collection bottle is connected to the other end of the condenser tube to collect the condensed liquid. The connecting pipe 102 can stably realize the material transmission between the heating bottle 4 and the condensation collection subassembly 5 through such a connection structure, and it is also convenient to disassemble and replace the three in different size specifications, reducing the inconvenience and limitations in use.

[0027] Please refer to Figures 3 to 5 The transmission mechanism includes a gear ring 106 integrally arranged on the side wall of the annular turntable 105, the gear ring 106 is meshed and connected with a side gear 107, the gear 107 is fixedly sleeved on one end of the output shaft of a rotary motor 108, and the rotary motor 108 is fixedly installed in the mounting hole formed on the upper surface of the shell 101.

[0028] When the rotary motor 108 starts, the output shaft drives the gear 107 to rotate, and due to the meshing relationship between the gear ring 106 and the gear 107, the annular turntable 105 starts to rotate on the inner wall at the bottom of the shell 101. The transmission mode is simple in structure and high in transmission efficiency, which can stably transmit the power of the rotary motor 108 to the annular turntable 105, ensuring that the heating bottle 4 rotates stably and continuously, effectively improving the stability and efficiency of the evaporation process.

[0029] Further, the spacing adjusting mechanism comprises two oppositely arranged connecting parts 112, one end of each connecting part 112 is fixedly connected to the side surface of the corresponding adjusting slide rod 110, the other end surface of the two connecting parts 112 is provided with a threaded hole and is threadedly connected to the two ends of the bidirectional threaded rod 113, the bidirectional threaded rod 113 is rotatably connected between the opposite side surfaces of the two vertical plates 114, the bottom ends of the two vertical plates 114 are fixedly connected to the upper surface of the annular turntable 105, a first bevel gear 115 is fixedly sleeved in the middle of the bidirectional threaded rod 113, the first bevel gear 115 is meshingly connected with a second bevel gear 116 on one side, the second bevel gear 116 is fixedly sleeved at the bottom end of an adjusting shaft 117, the adjusting shaft 117 is rotatably installed in the connecting hole provided through the upper surface of the mounting slide block 118, the mounting slide block 118 is slidingly connected to the edge of the upper extension hole, and the side surfaces of the mounting slide block 118 are fixedly connected to the corresponding vertical plate 114 on the side through the connecting rod 119.

[0030] When the adjusting shaft 117 is rotated, the second bevel gear 116 is driven to rotate, thereby driving the first bevel gear 115 to rotate, and the bidirectional threaded rod 113 is rotated, and due to the threaded connection, the two connecting parts 112 are synchronously and oppositely moved on the bidirectional threaded rod 113, thereby driving the adjusting slide rod 110 and the arc-shaped clamping block 111 to move and changing the spacing. The spacing adjusting mechanism is convenient and accurate to operate, can quickly adapt to connecting pipes 102 of different sizes, improves the applicability of the device, and reduces the use limitation caused by the size problem of the connecting pipe 102.

[0031] Further, a clamping groove 120 is formed in the side surface of the mounting slide block 118, the clamping groove 120 is clamped on the edge of the upper extension hole, clamping teeth 121 are integrally arranged on the inner walls at the top and bottom of the clamping groove 120, each clamping tooth 121 is slidingly clamped in the corresponding annular limiting sliding groove 122, and the two annular limiting sliding grooves 122 are formed in the top surface and the inner wall of the top of the shell 101.

[0032] A clamping groove 120 is formed on one side surface of the installation sliding block 118, which is clamped on the edge of the extension hole. The top and bottom inner walls of the clamping groove 120 are integrally provided with clamping teeth 121, which are respectively clamped in the annular limiting sliding groove 122 formed on the top surface and the top inner wall of the shell 101. In this way, the installation sliding block 118 can stably slide along the edge of the extension hole under the limitation of the annular limiting sliding groove 122, avoiding shaking or disengagement during adjustment. The stability and reliability of the movement of the installation sliding block 118 are enhanced, ensuring the accuracy and stability of the spacing adjustment mechanism during operation, and further improving the overall working performance of the device.

[0033] Further, the two arc-shaped clamping blocks 111 are provided with anti-skid protective rubber pads on the opposite side surfaces.

[0034] The two arc-shaped clamping blocks 111 are provided with anti-skid protective rubber pads on the opposite side surfaces, and the rubber pad material is usually made of rubber or other materials with high friction and softness. When the arc-shaped clamping block 111 clamps the connecting pipe 102, the rubber pad is in close contact with the connecting pipe 102, providing sufficient friction. This effectively improves the stability and safety of the clamping of the connecting pipe 102, avoids experimental accidents caused by the sliding of the connecting pipe 102, and protects the connecting pipe 102, prolonging its service life.

[0035] Further, a damping structure is provided between the adjustment rotating shaft 117 and the installation sliding block 118.

[0036] The damping structure can be realized by using a damping bearing or applying damping grease at the connection part. For example, when a damping bearing is used, it is installed between the connection holes of the adjustment rotating shaft 117 and the installation sliding block 118, so that the adjustment rotating shaft 117 is subjected to a certain resistance when rotating. When the annular turntable 105 rotates, the damping structure can effectively prevent the adjustment rotating shaft 117 from rotating due to inertia or vibration. This ensures the stability of the arc-shaped clamping block 111 after clamping the connecting pipe 102, so that even if the device is affected by external forces such as vibration during operation, the clamping state of the connecting pipe 102 can be maintained, ensuring the smooth progress of the experiment.

[0037] Please refer to Figure 6 , the lifting support 2 includes a stand 201, a lifting sliding groove 202 is formed on one side surface of the stand 201, a sliding block 203 is slidably connected in the lifting sliding groove 202, a screw hole is formed through the upper surface of the sliding block 203, a lifting screw 204 is threadedly connected in the screw hole, the bottom end of the lifting screw 204 is rotatably connected to the bottom inner wall of the lifting sliding groove 202, the top end of the lifting screw 204 extends to the outside of the stand 201 through a through hole and is fixedly sleeved with an adjustment knob 205, and one side surface of the sliding block 203 is connected with the shell 101 through a connecting piece.

[0038] Rotating the adjusting knob 205, the lifting screw 204 rotates, and due to the threaded action, the sliding block 203 moves up and down in the lifting chute 202, and the whole shell 101 and other components are lifted through the connecting piece. It is convenient for the operator to adjust the height of the device according to the actual needs, improve the use convenience and adaptability of the device, and meet the different experimental bench height and experimental operation requirements.

[0039] Further, the connecting piece is a damping rotating shaft 206, one end of the damping rotating shaft 206 is rotatably connected to one side surface of the sliding block 203 and the connection is provided with a damping structure, and the other end of the damping rotating shaft 206 is fixedly connected to one end surface of the shell 101.

[0040] One end of the damping rotating shaft 206 is rotatably connected to one side surface of the sliding block 203, and the connection is provided with a damping structure, which can be realized by built-in damping sheets or smearing damping oil, etc. The other end of the damping rotating shaft 206 is fixedly connected to one end surface of the shell 101. When the angle of the device needs to be adjusted, a certain external force is applied to overcome the damping force, and the shell 101 can be rotated, and after being adjusted to the appropriate angle, the device can be kept stable under the action of the damping structure. It provides more flexibility for experimental operation, and can adjust the angle of the device according to the experimental needs, while keeping stable during normal use, avoiding the influence of random angle change on the experimental effect, and further improving the practicability of the device.

[0041] Working principle: first, according to the diameter of the connecting pipe 102, rotate the adjusting rotating shaft 117, adjust the distance between the two arc-shaped clamping blocks 111 through the distance adjusting mechanism, so as to clamp the connecting pipe 102; then threadedly connect the heating flask 4 with one end of the connecting pipe 102, and threadedly connect the condensing pipe of the condensing and collecting assembly 5 with the other end of the communication sleeve 103; then according to the actual needs, rotate the adjusting knob 205, and adjust the overall height of the device by using the lifting bracket 2. Turn on the rotating motor 108, which drives the gear 107 to rotate, and then drives the annular turntable 105 to rotate, and drives the heating flask 4 to rotate in the heating bath 3. The sample in the heating flask 4 is evenly heated and evaporated. The gas generated by evaporation enters the condensing pipe of the condensing and collecting assembly 5 through the connecting pipe 102 and the communication sleeve 103, the cooling liquid in the condensing pipe circulates, the gas is liquefied by cooling, and finally collected in the collecting bottle.

[0042] It should be noted that the specific model and specification of the rotating motor 108 and the heating bath 3 need to be determined according to the actual specification of the device, and the specific selection calculation method adopts the existing technology in the art, so it will not be described in detail.

[0043] The power supply and principle of the rotating motor 108 and the heating bath 3 are clear to those skilled in the art, and will not be described in detail here.
