Description

Technical Field

[0001] This utility model relates to the field of rotary evaporator technology, and in particular to a novel rotary evaporator. Background Technology

[0002] A rotary evaporator, also known as a rotary evaporator, is a laboratory device widely used in fields such as chemistry, chemical engineering, and biomedicine. Its basic principle is to use the dual effects of heating and depressurization to evaporate volatile substances from liquid samples, which are then cooled and collected by a condenser.

[0003] A search revealed Chinese patent application CN222400266U, which discloses a novel rotary evaporator. Through the cooperation of a connecting block structure and a limiting structure, the position of the locking block structure can be limited. Then, by utilizing the cooperation of several locking blocks, the connection between distillation flasks of different sizes and the rotating rod can be constrained, thereby improving the flexibility and versatility of the device. However, this novel rotary evaporator in the aforementioned patent has the following drawbacks: The rotary evaporator has a receiving bottle attached to the bottom of the condenser. When too much is collected, the receiving bottle becomes heavy and cannot be easily supported, leading to significant weight and a tendency to fall off. Furthermore, it cannot limit the condenser's position during use, resulting in instability during subsequent replacement and installation. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the receiving bottle is too heavy when too much is collected, making it difficult to support and causing it to fall off due to gravity. In addition, the condenser cannot be limited during use, leading to instability during subsequent replacement and installation. Therefore, a new type of rotary evaporator is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel rotary evaporator includes a base, a base plate, and a hydraulic rod. A heating pot is fixedly mounted on the top of the base, and a control panel is provided on the heating pot. A back plate frame is fixedly mounted on the top of the base, and a power source is movably mounted on the front end of the back plate frame. A distillation flask is mounted at the output end of the power source. A condenser that mates with the distillation flask is mounted at the front end of the back plate frame. A receiving bottle is provided at the bottom of the condenser. The base plate is fixedly mounted on the top of the base, and a threaded sleeve is threaded onto the top of the base plate. A movable sleeve is fixedly mounted on the outer side of the threaded sleeve. A support plate is movably connected to the top of the movable sleeve via a compression rod. A movable rod is movably mounted on the outer side of the back plate frame, and a clamping plate corresponding to the condenser is movably connected to the front end of the movable rod.

[0007] As a preferred technical solution of this application, the base plate and the threaded sleeve are threadedly installed through a threaded rod, and a motor that mates with the threaded rod is fixedly installed on one side of the base plate.

[0008] As a preferred technical solution of this application, a sliding rod that cooperates with the movable sleeve is fixedly installed on the top of the base plate, the support plate and the base plate are movably connected by a telescopic rod, and a sliding groove corresponding to the support plate is provided on one side of the heating pot.

[0009] As a preferred technical solution of this application, the back plate frame and the movable rod are movably installed through a limiting post, and the movable rod is provided with a movable groove that cooperates with the limiting post.

[0010] As a preferred technical solution of this application, the rear end of the movable rod is movably connected to the back plate frame via a hydraulic rod, and the hydraulic rod and the movable rod are movably connected via a push block.

[0011] As a preferred technical solution of this application, the clamping plate and the movable rod are movably installed through a connecting seat, and a protective pad is provided on the inner side of the clamping plate.

[0012] Compared with the prior art, this utility model provides a novel rotary evaporator with the following advantages:

[0013] 1. This novel rotary evaporator, through the cooperation between the support plate, threaded rod, sliding rod and threaded sleeve, achieves upward pressing of the extrusion rod, so that the support plate can slide along the inner side of the sliding groove, and the support plate can support the receiving bottle. This solves the problem in the prior art where the bottom of the condenser is connected to the receiving bottle, and the receiving bottle is heavy when too much is collected, making it difficult to support and causing it to fall off due to the large gravity.

[0014] 2. This new rotary evaporator, through the cooperation between the movable rod, clamping plate, movable groove and hydraulic rod, realizes the extension and retraction of the hydraulic rod to drive the movable rod to move, and uses the clamping plate to limit the condenser. This solves the problem in the existing technology that the condenser cannot be limited during use and is unstable during subsequent replacement and installation. Attached Figure Description

The base plate 2 and the threaded sleeve 204 are threadedly installed through the threaded rod 203. A motor 202 that cooperates with the threaded rod 203 is fixedly installed on one side of the base plate 2. This allows the threaded sleeve 204 to drive the movable sleeve 205 to slide along the outer side of the sliding rod 206 during movement. During the movement of the movable sleeve 205, the support plate 208 is extruded, allowing the support plate 208 to move upward. The top of the support plate 208 can support the receiving bottle 107 at the bottom of the condenser 106.

[0023] Reference Figures 1-4 Furthermore, the base plate 2 has a sliding rod 206 fixedly installed on its top, which cooperates with the movable sleeve 205. The support plate 208 is movably connected to the base plate 2 via a telescopic rod 201. A sliding groove 209 corresponding to the support plate 208 is provided on one side of the heating pot 101. The back plate frame 103 is movably installed with the movable rod 302 via a limiting post 303. The movable rod 302 has a movable groove 306 that cooperates with the limiting post 303. During the movement of the threaded sleeve 204, the movable sleeve 205 can slide along the outside of the sliding rod 206.
