Description

Technical Field

[0001] The present application belongs to the technical field of biochemical instruments, and in particular to an evaporation rack used in chemical reactions. Background Art

[0002] In the process of pharmaceutical research and development, in order to achieve the required reaction conditions, the container containing the mixed solution needs to be heated in a water bath so that the relevant liquid in the container evaporates continuously during the heating process. Due to the requirements of the reaction, the container needs to be half-submerged in water in a certain tilted posture during this process, and it is hoped that it will rotate during the heating and evaporation process, so that the reaction can be more complete and local uneven heating can be avoided. The conventional operation method is that the operator clamps the container through a clamping device, and adjusts and rotates the posture after a certain period of time based on experience. This method requires the operator to have a high degree of proficiency and needs to take protective measures to avoid burns caused by operating errors. Some manufacturers will consider using expensive multi-axis manipulators to complete the above actions, but this is not conducive to cost control. Utility Model Content

[0009] A rotating arm, one end of which is connected to the output shaft of the second motor and the other end of which is connected to a long frame;

[0010] The plug connector is rotated and passed through the long frame, one end of which is used to connect to the evaporation container, and the other end is used to connect to the exhaust pipe. The outer periphery of the section of the plug connector located in the long frame is provided with a tooth portion, and a driving gear is provided in the long frame. The driving gear is meshed with the tooth portion and connected to the output shaft of the third motor arranged on the long frame.

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0018] The present application embodiment provides an evaporation rack, such as Figure 1-Figure 2 As shown, it includes an annular guide rail 1, a moving plate 20, a lifting block 30, a rotating arm 40, a plug connector 42 and the like.

[0019] Among them, the annular guide rail 1 is arranged at a predetermined distance on the outer peripheral side of the water bath evaporator 10; the movable plate 20 is slidably matched with the annular guide rail 1. Specifically, in order to improve the stability of the movable plate 20 and the objects arranged thereon, arc-shaped clamping plates can be arranged on both sides of the movable plate 20, so that the arc-shaped clamping plates are matched with the inner and outer walls of the annular guide rail 1, thereby improving the structural stability.

[0020] The movable plate 20 is provided with a vertical lifting mechanism, and the lifting block 30 is provided at the movable end of the vertical lifting mechanism, and the vertical lifting mechanism is used to drive the lifting block 30 to move up and down. Figure 1-Figure 2 The schematic diagram of the structure of a vertical lifting mechanism is shown, which includes a guide rod 21 arranged on a moving plate 20, an upper plate 22 is arranged on the top of the guide rod 21, a first motor 24 is arranged on the upper plate 22, an output shaft of the first motor 24 passes through the upper plate 22 and is connected to a screw rod 23, the lower end of the screw rod 23 is rotatably connected to the moving plate 20, and a lifting block 30 is passed through the guide rod 21 and threadedly engaged with the screw rod 23. The screw rod 23 is driven to rotate by the first motor 24, so that the lifting block 30 is lifted and lowered along the guide rod 21. According to actual needs, other vertical linear mechanisms can also be used to achieve this.

[0021] The lifting block 30 is provided with a second motor 32, the output shaft of which is parallel to the length direction of the lifting block 30; one end of the rotating arm 40 is connected to the output shaft of the second motor 32, and the other end is connected to the long frame 41. The plug connector 42 is rotated through the long frame 41.

[0022] Preferably, in order to improve the adaptable posture adjustment and specifically realize the adjustment of the position of the plug connector 42, the lifting block 30 is provided with a telescopic portion 31 along its own length direction, for example, the telescopic portion 31 is inserted from the lifting block 30 into the lifting block 30 to realize telescopic movement, and the telescopic portion 31 can be fixed by a locking bolt arranged on the lifting block 30 after telescopic movement. The second motor 32 is arranged on the telescopic portion 31, so that the position of the plug connector 42 above the water bath evaporator 10 can be adjusted. Specifically, the length direction of the long frame 41 and the length direction of the lifting block 30 can be set to be parallel, so that the extension and retraction of the telescopic portion 31 can correspond to the position movement of the plug connector 42.

[0023] Combination Figure 1-Figure 3 The plug connector 42 includes a main body portion located in the long frame 41, an upper end portion 422 extending from one side of the long frame 41 for connecting to the exhaust pipe, and a lower end portion 421 extending from the other side of the long frame 41 for connecting to the evaporation container 11. A tooth portion 423 is formed on the upper periphery of the main body portion, and a driving gear 424 is provided in the long frame 41. The driving gear 424 is meshed with the tooth portion 423 and connected to the output shaft of the third motor 425 provided on the long frame 41. Specifically, the lower end portion 421 can be plugged and matched with the evaporation container 11 through a rubber joint, and a locking clip can also be provided on the lower end portion 421 to improve the stability of the plug-in fit. The connection between the upper end portion 422 and the exhaust pipe can also be operated similarly. Considering that the movable plate 20 can move along the annular guide rail 1, the exhaust pipe can be matched with the upper end portion 422 through a universal joint to avoid interference with the exhaust pipe when the evaporation rack as a whole moves in an annular manner around the water bath evaporator 10.

[0024] In actual application, the solution to be evaporated is first placed in the evaporation container 1, the evaporation container 1 is matched with the lower end 421, and the upper end 422 is connected to the exhaust pipe. Then, the extension length is adjusted by the telescopic portion 31 to adjust the position of the evaporation container 1, and the height is adjusted by the first motor 24, and the tilt posture is adjusted by the second motor 32 to achieve the required tilt degree, and the part of the evaporation container 1 that needs to be submerged in water is as close to the middle of the water bath evaporator 10 as possible, and then the water bath evaporator 10 is turned on for heating and evaporation.

[0025] During this process, the third motor 425 can be used to drive the driving gear 424 to rotate, and the rotational force can be transmitted through the tooth portion 423 to rotate the plug connector 42, so that the evaporation container 1 can rotate along its own axis; and / or, the movable plate 20 starts to move along the annular guide rail 1, so that the lower end of the evaporation container 1 is around the position of approximately the middle of the water bath evaporator 10; the above method improves the uniformity of heating and evaporation.

[0026] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
