DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-3 The utility model provides an implementation scheme: at present, the feeding of the rotary evaporator during use is mainly divided into two methods: one is to remove the distillation flask 6 for feeding and the other is to directly feed the material through the pipeline connected to the distillation flask 6. The former is cumbersome and inefficient, while the latter often penetrates the bottle body on one side of the condenser 4, resulting in a long pipeline with a complex structure and easy damage.
[0022] In order to solve the above problems, the present application discloses a rotary evaporator that is easy to load. The device uses a base 1 as a main body supported by the bottom, a bracket 2 is assembled on the base 1, a heater 3 is arranged on one side of the bracket 2, and a mounting and rotating mechanism of a distillation device is arranged on the bracket 2. The rotating mechanism can drive a connecting section 5 to rotate, a distillation flask 6 is connected to the connecting section 5, and the body of the distillation flask 6 is placed on the heater 3, so that the connecting section 5 drives the body of the distillation flask 6 to rotate on the heater 3, and the distillation flask 6 is rotated by the heater 3. A condenser 4 is arranged on one side of the bracket 2, and a collecting bottle 7 is connected to the bottom of the condenser 4 through a clamp to condense the evaporated distillate;
[0023] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned connecting joint 5 is a pipe fitting with two sections of shaft ends facing each other and movably connected. The connecting joint 5 is divided into a fixed joint 501 and a rotating joint 502. The fixed joint 501 and the connecting joint 5 are movably connected in a plug-in manner, so that the rotating joint 502 can rotate independently. The fixed joint 501 is fixedly connected to the rotating mechanism and the shaft end is connected to the condenser 4. The rotating joint 502 is connected to the bottle mouth of the distillation flask 6. The connecting joint 5 not only serves to connect the distillation flask 6 and the condenser 4, but also serves to install and rotate the distillation flask 6.
[0024] Furthermore, in order to shorten the feeding distance, a feeding interface 8 is provided on the fixed section 501, a feeding hopper 9 is threadedly connected to the feeding interface 8, an L-shaped insert tube 10 extends from the bottom end of the feeding interface 8, the tube end of the L-shaped insert tube 10 extends beyond the connection position between the rotating section 502 and the bottle mouth of the distillation flask 6, and a closing valve 11 is provided on the feeding interface 8;
[0025] In the specific implementation process, since the fixed section 501 and the rotating mechanism and the bracket 2 can remain relatively still, an opening is made in the radial direction of the fixed section 501, and a feed interface 8 is set at the opening. The feeding hopper 9 is connected through the feed interface 8, and the material is added to the feed interface 8 through the feeding hopper 9. The material is transported through the L-shaped cannula 10 that extends obliquely to the mouth of the distillation flask 6. Specifically, the L-shaped cannula 10 coincides with the axis of the rotating section 502, so that the rotation of the distillation flask 6 during feeding will not affect the flow of steam. The feed interface 8 can be closed by closing the valve 11, thereby blocking the connection between the feeding hopper 9 and the L-shaped cannula 10, thereby preventing the distillate from overflowing when no feeding is done.
[0026] As a preferred solution, further, a tubular structure with threads on the bottom is extended from the bottom end of the feeding hopper 9 and is threadedly connected to the feed interface 8 to facilitate disassembly and maintenance.
[0027] As a preferred solution, further, the relative axial ends of the fixed joint 501 and the rotating joint 502 are specifically connected by a socket structure and have an axial limiting structure to prevent the fixed joint 501 and the rotating joint 502 from axially moving in series.
[0028] As a preferred solution, further, the bottom end of the bracket 2 is connected to a lifting arm 12, and a control panel 13 is also provided on the base 1 and connected to the heater 3. The overall height of the distillation can be adjusted by the lifting arm 12 to play a regulating role. The control panel 13 acts on the heater 3 to adjust the temperature of the heater 3.
[0029] As a preferred solution, further, according to the attached description Figure 1-3 It can be seen that the above-mentioned rotating mechanism also includes a driving motor 14. The driving motor 14 is arranged at the top of the bracket 2. An extension arm 15 extends from one side of the driving end of the driving motor 14. A driving shaft 16 is arranged in the extension arm 15 and connected to the driving end of the driving motor 14. The end of the driving shaft 16 is connected to a gear set 17 and linked to the rotating joint 502.
[0030] During the specific implementation process, the driving motor 14 drives the driving shaft 16 to rotate, thereby causing the driving shaft 16 to rotate in conjunction with the gear set 17, and the gear set 17 drives the rotating joint 502 to rotate, thereby driving the distillation flask 6 connected to the rotating joint 502 to rotate, and the extension arm 15 plays a role in wrapping and limiting the driving shaft 16, and plays a role in installing and positioning the connecting joint 5.
[0031] As a preferred solution, further, the end of the extension arm 15 is fixedly connected to the fixing section 501 .
[0032] From the above, it can be generally known that the rotary evaporator which is convenient for loading adopts two independently arranged and movably connected connecting sections 5 as the distillation pipeline, and a feeding pipeline axially extending to the bottle mouth of the distillation flask 6 is arranged on the fixed section 501. At the same time, a feeding hopper 9 is arranged and separated by a valve. On the one hand, it is convenient to load materials during the evaporation process, and on the other hand, feeding is carried out through the feeding pipeline closer to the distillation flask 6, which effectively shortens the pipeline, improves the structural strength, and has a simple structure and convenient operation.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
