Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, and more specifically, to a mixing and stirring device for laboratory use. Background Technology
[0002] A mixing device is a mechanical device used to mix, disperse, or promote reactions of different substances. It is widely used in industries such as chemical, food, pharmaceutical, and environmental protection. Its core components include agitators (such as impellers, turbines, and augers), drive motors, transmission mechanisms, and containers. During operation, the motor drives the agitator to rotate through a reducer, generating shear force, convection, and turbulence, thereby achieving mixing, suspension, dissolution, or heat transfer of materials. Depending on the process requirements, mixing devices can be divided into vertical, horizontal, and magnetically driven types. The materials are mostly stainless steel, carbon steel, or anti-corrosion coatings to adapt to different media. In emerging fields such as new energy and nanomaterials, high-precision mixing devices play a key role in process optimization.
[0003] A search revealed that CN213434242U discloses a laboratory stirring device that addresses the problem of "multiple connections of the stirring device having a high probability of loosening, resulting in poor stirring effect." The device uses a truncated cone base and a base to clamp and fix the vertical rod, reducing the probability of loosening. However, during mixing, the lack of a sealed top for the container allows liquid materials inside to easily splash onto the worktable and stirring equipment. Since some liquid materials are corrosive, this can damage the production equipment and environment, thus requiring improvement. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a mixing and stirring device for laboratory use, which has the advantage of preventing splashing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing and stirring device for laboratory use, comprising a base plate, a fixed frame fixedly connected to the top of the base plate, a movable plate movably connected to the inner cavity of the fixed frame, a pull rod movably sleeved inside the bottom of the movable plate, the other end of the pull rod penetrating the movable plate and extending to the outside of the movable plate and fixedly connected to a first movable block, a first connecting block movably sleeved on the outer surface of the pull rod, a rotating rod movably connected to the outer surface of the first movable block, the top of the rotating rod movably sleeved with the bottom of the movable plate, a second movable block movably connected inside the rotating rod, a second connecting block fixedly connected to the top of the second movable block, the top of the second connecting block movably connected to the inner bottom of the movable plate, two sealing plates fixedly connected to each other, the two sealing plates being movably connected, a spring fixedly connected to the left side of the first connecting block, the other end of the spring being fixedly connected to the outer surface of the movable plate.

[0008] As a preferred embodiment of this utility model, a second motor is fixedly connected to the top of the mounting bracket, and a threaded rod is fixedly sleeved on the other end of the output shaft of the second motor. The other end of the threaded rod passes through the mounting bracket and extends to the outside of the mounting bracket and is movably sleeved with the top of the base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention, by incorporating a rotating rod, a second movable block, a second connecting block, a sealing plate, and a movable plate, allows for the release of the seal on the top of the container to facilitate the removal of the stirring blades. Pulling the rod causes the first connecting block to overcome the spring force and move horizontally to the left. Simultaneously, the first movable block moves to the left, pressing and pushing the rotating rod, causing it to rotate and press and push the second movable block. The second movable block then drives the second connecting block, under the limiting effect of the movable plate, to move in the opposite direction to the movement of the first movable block. Ultimately, the first and second connecting blocks drive the two sealing plates to move horizontally in opposite directions. When the rod is released, the elastic force of the movable plate causes the two sealing plates to quickly reset, restoring the seal on the container. This design achieves a complete seal on the top of the container during the mixing process, preventing splashing of internal liquid materials. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] like Figures 1 to 5 As shown, this utility model provides a mixing and stirring device for laboratory use, including a base plate 1. A fixed frame 2 is fixedly connected to the top of the base plate 1. A movable plate 28 is movably connected to the inner cavity of the fixed frame 2. A pull rod 3 is movably sleeved inside the bottom of the movable plate 28. The other end of the pull rod 3 passes through the movable plate 28 and extends to the outside of the movable plate 28 and is fixedly connected to a first movable block 5. A first connecting block 4 is movably sleeved on the outer surface of the pull rod 3. A rotating rod 6 is movably connected to the outer surface of the first movable block 5. The top of the rotating rod 6 is movably sleeved with the bottom of the movable plate 28. A second movable block 7 is movably connected inside the rotating rod 6. A second connecting block 8 is fixedly connected to the top of the second movable block 7. The top of the second connecting block 8 is movably connected to the inside of the bottom of the movable plate 28. The other ends of the first connecting block 4 and the second connecting block 8 are both fixedly connected to... There are two sealing plates 9 connected together. A spring 27 is fixedly connected to the left side of the first connecting block 4, and the other end of the spring 27 is fixedly connected to the outer surface of the moving plate 28. When the pull rod 3 is pulled outward, the first connecting block 4 will overcome the elastic force of the spring 27 and move horizontally to the left. At this time, the first moving block 5 moves to the left synchronously with the first connecting block 4, and the first moving block 5 squeezes and pushes the rotating rod 6, causing the rotating rod 6 to rotate. The rotating rod 6 then squeezes and pushes the second moving block 7. At this time, the second moving block 7 will drive the second connecting block 8 to move in the opposite direction to the movement of the first moving block 5 under the limiting action of the moving plate 28. Finally, the first connecting block 4 and the second connecting block 8 will drive the two sealing plates 9 to move horizontally in opposite directions.
[0022] Among them, a turntable 10 is movably sleeved on the top of the base plate 1, and a fixed sleeve 11 is fixedly connected to the top of the turntable 10. A material container 12 is movably sleeved inside the fixed sleeve 11, and the top of the material container 12 is movably connected to the bottom of the sealing plate 9. When the two sealing plates 9 cover the top of the material container 12, the top of the material container 12 will be sealed.
[0023] The base plate 1 has a mounting bracket 13 fixedly connected to the rear of the top. The mounting bracket 13 has a telescopic plate 14 movably sleeved inside. The top of the telescopic plate 14 is fixedly connected to a first motor 15. The other end of the output shaft of the first motor 15 is fixedly sleeved with a rotating shaft 16. The other end of the rotating shaft 16 passes through the telescopic plate 14 and extends to the outside of the telescopic plate 14, and is fixedly sleeved with a stirring blade 17. When the first motor 15 starts running, the rotating shaft 16 will drive the stirring blade 17 to rotate.
[0024] The top of the mounting bracket 13 is fixedly connected to a second motor 18, and the other end of the output shaft of the second motor 18 is fixedly sleeved with a threaded rod 19. The other end of the threaded rod 19 passes through the mounting bracket 13 and extends to the outside of the mounting bracket 13 and is movably sleeved with the top of the base plate 1. When the second motor 18 starts running, it will cause the threaded rod 19 to rotate.
[0025] The threaded rod 19 has a sliding block 20 threadedly connected to its outer surface. The outer surface of the sliding block 20 is movably connected to the interior of the mounting frame 13. The right side of the sliding block 20 is fixedly connected to the left side of the telescopic plate 14. When the threaded rod 19 rotates, the sliding block 20 will cause the telescopic plate 14 to move vertically up and down under the limiting action of the mounting frame 13.
[0026] The top of the fixed frame 2 is fixedly connected to a support base 21. A drive motor 22 is fixedly installed inside the support base 21. A rotating rod 23 is fixedly sleeved at the other end of the output shaft of the drive motor 22. A rotating rod 24 is fixedly sleeved at the other end of the rotating rod 23. A sleeve rod 25 is movably connected to the outer surface of the rotating rod 24. When the drive motor 22 starts running, the rotating rod 23 will drive the rotating rod 24 to rotate, and the rotating rod 24 will squeeze and push the sleeve rod 25.
[0027] The bottom of the sleeve rod 25 is fixedly connected to a vertical rod 26. The other end of the vertical rod 26 passes through the fixed frame 2 and extends into the inner cavity of the fixed frame 2 and is fixedly connected to the top of the movable plate 28. When the sleeve rod 25 moves, the vertical rod 26 will drive the movable plate 28 to move vertically up and down under the limiting action of the fixed frame 2.
[0028] Working principle and usage process of this utility model:
[0029] The first motor 15 is started, causing the rotating shaft 16 to drive the stirring blade 17 to rotate, and the stirring and mixing operation will be carried out. At the same time, the drive motor 22 is started, causing the rotating rod 23 to drive the rotating rod 24 to rotate, and the rotating rod 24 to squeeze and push the sleeve rod 25. The sleeve rod 25 drives the vertical rod 26 and the moving plate 28 to move vertically downward under the limiting action of the fixed frame 2, so that the moving plate 28 can be adapted to the material container 12 of different heights, thereby improving the applicability of the closed plate 9.
[0030] When mixing is complete, it is necessary to release the seal on the container 12 to facilitate the removal of the mixing blade 17. At this time, pull the lever 3, causing the first connecting block 4 to overcome the elastic force of the spring 27 and move horizontally to the left. Simultaneously, the first movable block 5 moves to the left in sync with the first connecting block 4, pressing and pushing the rotating rod 6, causing the rotating rod 6 to rotate. This, in turn, causes the rotating rod 6 to press and push the second movable block 7. The second movable block 7 then drives the second connecting block 8, under the limiting action of the moving plate 28, to move in the opposite direction to the movement of the first movable block 5, ultimately... Connecting blocks 4 and 8 drive the two sealing plates 9 to move horizontally in opposite directions. When the lever 3 is released, the elastic force of the moving plate 28 causes the two sealing plates 9 to quickly reset, thus restoring the sealing effect on the container 12. The above design achieves a full sealing effect on the top of the container 12 during the mixing process, preventing the internal liquid material from splashing. Then, the second motor 18 is started, causing the threaded rod 19 to rotate and the sliding block 20 to drive the telescopic plate 14 and the stirring blade 17 to move vertically upward, removing the stirring blade 17.
