Description

Technical Field

[0001] This utility model relates to stirrers, specifically to stirrers used in organic synthesis experiments. Background Technology

[0002] In organic synthesis experiments, chemicals need to be added to a stirred tank and then stirred by a stirrer to ensure a thorough chemical reaction. However, in current technologies, most stirrers are fixed on the stirred tank and remain vertically constant relative to it. This results in the chemicals at the bottom of the stirred tank being either not stirred or only minimally stirred. For example, Chinese utility model patent application number CN2023234362474.9 discloses a novel chemical gas-liquid mixing agitator, including a tank body. A connecting pipe is fixedly welded to the lower end of one side of the tank body, and a sampling tube is fixedly connected to one end of the connecting pipe. A screw is threadedly connected to the inside of the sampling tube, and a sliding block is fixedly connected to the lower end of the screw. A sealing plug is slidably fitted onto the outside of the sliding block. When a sampling bottle is placed below the sampling tube, rotating the screw moves the sliding block upward, causing the sealing plug to move upward as well. Liquid inside the tank flows downward from the sampling tube into the sampling bottle for sampling and testing. The design of the sliding block facilitates the longitudinal movement of the sealing plug, reducing wear and tear on the sealing plug and sampling tube. By rotating and removing the screw, the cover is unrestrained, allowing it to be moved upward to disassemble the mixing device for maintenance of the tank interior. However, the agitator disclosed in this patent cannot achieve sufficient mixing and stirring of the chemical substances at the bottom of the mixing tank. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stirrer for organic synthesis experiments.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a stirrer for organic synthesis experiments, comprising:

[0005] Cable;

[0006] A handwheel and a wheel are provided. One end of the cable is fixedly connected to the wheel. When the handwheel is rotated, it drives the wheel to rotate, thereby causing the cable to move by the wheel.

[0007] The system includes a drive motor, a rotating rod, and a stirring blade. One end of the rotating rod is fixedly connected to the stirring blade, and the other end of the rotating rod is fixedly connected to the drive motor, thereby causing the drive motor to drive the stirring blade to rotate. The stirring blade is used for stirring.

[0008] The other end of the cable is connected to the drive motor, so that when the handwheel is rotated, it drives the cable to move. The movement of the cable drives the drive motor to rise and fall in the vertical direction, thereby driving the stirring blade to rise and fall in the vertical direction.

[0009] In some embodiments of this application, a reducer, a first rotating shaft, and a second rotating shaft are also included. The first rotating shaft and the second rotating shaft are both connected to the reducer. The handwheel is fixedly installed together with the first rotating shaft, and the wheel is fixedly installed together with the second rotating shaft, so that the high speed of the handwheel is converted into the low speed of the wheel by the reducer.

[0010] In some embodiments of this application, a first mounting bracket and a first fixed wheel are also included. The first fixed wheel is fixedly mounted on the first mounting bracket and is rotatable relative to the first mounting bracket. The cable is wound around the first fixed wheel, and when the cable moves, it drives the first fixed wheel to rotate on the first mounting bracket.

[0011] In some embodiments of this application, a second fixed wheel, a third fixed wheel, and a second mounting bracket are also included. The second fixed wheel and the third fixed wheel are both fixedly mounted on the second mounting bracket, and both the second fixed wheel and the third fixed wheel are rotatable relative to the second mounting bracket. The cable is wound around the second fixed wheel and the third fixed wheel, and when the cable moves, it drives the second fixed wheel and the third fixed wheel to rotate on the second mounting bracket.

[0012] In some embodiments of this application, a support arm, a mounting support plate, and a connecting hook are also included. The drive motor is fixedly mounted on the mounting support plate, the support arm and the mounting support plate are fixedly connected together, the connecting hook is fixedly disposed on the support arm, and the other end of the cable is fixedly connected to the connecting hook, so that when the cable moves, it drives the support arm to move in the vertical direction, thereby driving the drive motor to move in the vertical direction.

[0013] In some embodiments of this application, a base frame, a first vertical frame, and a limiting frame are also included. One end of the first vertical frame is fixedly connected to the base frame. The limiting frame and the support arm are fixedly connected together. The first vertical frame is fitted into the limiting frame, so that when the cable drives the support arm to rise and fall, the limiting frame slides on the first vertical frame, thereby ensuring that the rise and fall of the support arm is more stable.

[0014] In some embodiments of this application, a first limiting wheel, a second limiting wheel, and a preset number of fixed rods are also included. The fixed rods are fixedly installed on the limiting frame. The first limiting wheel is fixedly installed on one of the fixed rods and can rotate on the fixed rod. The second limiting wheel is fixedly installed on another fixed rod and can rotate on the fixed rod. The first limiting wheel and the second limiting wheel clamp the first vertical frame, so that when the support arm drives the limiting frame to rise and fall, the first limiting wheel and the second limiting wheel slide on the first vertical frame.

[0015] In some embodiments of this application, a second vertical frame is also included, on which the reducer is fixedly mounted.

[0016] The beneficial effects of this application are as follows: The stirrer used in the organic synthesis experiment provided by this application has a simple structure. One end of the handwheel is connected to the cable, and the other end of the cable is connected to the support arm. The support arm is connected to the mounting support plate. The drive motor is mounted on the mounting support plate and connected to the rotating rod. The stirring blades are mounted on the rotating rod. By rotating the handwheel, the handwheel drives the cable to move, and the cable drives the mounting support plate to rise and fall, thereby driving the stirring blades to rise and fall. This allows the stirring blades to reach the bottom of the mixing tank 25, making the mixing more thorough and uniform. Attached Figure Description
