Description

Technical Field

[0001] The utility model belongs to the technical field of mixing instruments, and specifically relates to a vortex mixing instrument. Background Art

[0002] A vortex mixing instrument is a laboratory device used to quickly and evenly mix liquid samples. It generates rapid vortex motion to fully mix the components in the liquid, and is commonly used in fields such as biological, chemical, and medical research. The basic principle of a vortex mixer is to generate a vortex flow through a high-speed rotating rotor, thereby producing a strong mixing and oscillation effect inside the container. This instrument usually consists of three parts: a main body, a rotor, and a container. Among them, the main body is responsible for driving the rotor to rotate, the rotor generates a vortex flow through the frictional force with the inner wall of the container, and the container is used to hold the sample.

[0003] Existing vortex mixing instruments generate vortex flow through a high-speed rotating rotor, and this high-speed rotation inevitably generates mechanical vibrations. These vibrations not only affect the stability of the instrument, but may also cause unstable mixing effects of the samples, reducing the repeatability of experiments. During the experiment, if the instrument moves, it may cause liquid to splash out or cross-contamination of samples, bringing errors to the experimental results. Therefore, the requirements for stability in the actual operation of traditional vortex mixing instruments are not met.

[0004] In the patent with the publication number CN210045157U, a multi-point adjustable vortex mixer is disclosed. This type of mixing instrument is provided with a clamping groove, and a clamping slider is arranged in the clamping groove to fix the position of the test tube through the clamping slider. Through this design, it is convenient to position the test tube, thereby preventing the solution in the test tube from spilling. However, as can be seen from the drawings, the bottom of this type of vortex mixer is flat and no other anti-slip design is made. Therefore, when in use, the vortex mixer is very likely to slide due to the vibrations generated by its own operation. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a vortex mixing instrument to solve the following technical problems raised in the background art:

[0006] Existing vortex mixing instruments generate vortex flow through a high-speed rotating rotor, and this high-speed rotation inevitably generates mechanical vibrations, and the mixer body is very likely to move due to these vibrations.

[0007] To solve the above technical problems, the technical solution adopted by the utility model is:

[0012] Furthermore, a mounting plate is fixedly connected to the bottom of the central plate, and a washer is fixedly connected to the bottom of the mounting plate near the center.

[0013] Furthermore, a plurality of anti-slip grooves are arranged at the bottom of the washer, and the anti-slip grooves are evenly spaced along the circumferential direction.

[0014] Furthermore, at least four dampers are provided.

[0015] Furthermore, four dampers are provided, and the four dampers are respectively arranged at the front, rear, left, and right positions of the central plate.

[0016] Furthermore, the damper is arranged obliquely, one end of the damper is hinged to the bottom plate, and the other end is hinged to the central plate.

[0017] Furthermore, at least four first springs are provided.

[0018] Furthermore, five first springs are provided, and the five first springs are respectively arranged at the positions near the four corners of the central plate and the middle position of the central plate.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Embodiment:

[0032] A vortex mixer, hereinafter referred to as a mixer, as Figure 1As shown in the figure, it includes a body 1, a connector 2 and a base 3. The connector 2 is arranged at the top of the body 1 and is used to connect a container, and the base 3 is connected to the bottom of the body 1. Among them, the body 1 is used to make the connector 2 generate vibrations and vortices. Both the body 1 and the connector 2 adopt existing technologies. For example, the specific structure and working principle are described in the utility model patent document with the publication number CN220531384U. Therefore, the specific structure and principle will not be elaborated here one by one. The base 3 is connected to the bottom of the body 1, and the base 3 is used to stabilize the position of the body 1.

[0033] As Figure 3 shown, the base 3 includes a bottom plate 14, a support portion 7, a central plate 10, a first spring 13 and a damper 12;

[0034] As Figure 4 shown, the bottom plate 14 is fixedly connected to the body 1, and the support portion 7 is fixedly connected to the bottom of the bottom plate 14 near the outside; the central plate 10 is arranged at the bottom of the bottom plate 14 near the center, and both ends of the damper 12 are connected to the central plate 10 and the bottom plate 14 respectively; one end of the first spring 13 is connected to the bottom plate 14, and the other end is connected to the central plate 10. Among them, the support portion 7 is used to support the body 1 and stabilize the position of the body 1. The central plate 10 is used to contact the support surface and stabilize the position of the body 1 to prevent the body 1 from sliding.

[0035] Specifically, when the mixer works, the body 1 of the mixer generates vibrations, and the vibrations of the body 1 are transmitted to the bottom plate 14 and the support portion 7. The support portion 7 will generate slight jumps due to the vibrations, so that the body 1 may displace. Since a damper 12 and a first spring 13 are arranged between the support plate and the central plate 10, the first spring 13 can absorb vibrations through deformation, and the damper 12 can prevent the spring from rebounding and consume the potential energy stored by the spring due to deformation, thereby achieving the damping effect. Through this design, it can be ensured that the central plate 10 can stably contact the support surface, that is, it is not easy for the central plate 10 to generate relative movement with the support surface. When the body 1 has a tendency to displace, the central plate 10 can prevent the body 1 from displacing, that is, ensure the stability of the body 1. Through this design, the displacement problem generated in the use process of the existing equipment can be effectively solved. Through reasonable structural design and material selection, it is ensured that the equipment remains stable while mixing efficiently, which helps to improve the working efficiency of the laboratory and the accuracy of experimental results.

[0036] In a preferred embodiment, as Figure 2 and Figure 4As shown, a connecting plate 9 is fixedly connected to the bottom of the supporting part 7, and a cushion block 4 is fixedly connected to the bottom of the connecting plate 9. The cushion block 4 is made of rubber material. The cushion block 4 made of rubber material can reduce the noise generated by vibration. At the same time, the rubber material has good friction characteristics, which helps to prevent the vortex mixer from sliding during operation. By adding the cushion block 4 at the bottom of the supporting part 7, the friction force with the workbench surface can be effectively increased, and the stability of the equipment can be enhanced.

[0037] In a preferred embodiment, as Figure 2 and Figure 4 shown, a mounting plate 11 is fixedly connected to the bottom of the central plate 10, and a washer 5 is fixedly connected to the bottom of the mounting plate 11 near the center. Further optimized, a plurality of anti-slip grooves 6 are provided at the bottom of the washer 5, and the anti-slip grooves 6 are evenly spaced along the circumferential direction. The anti-slip grooves 6 can significantly enhance the friction force between the washer 5 and the contact surface. During the operation of the equipment, the anti-slip grooves 6 can effectively prevent the washer 5 from slipping, that is, prevent the central plate 10 from sliding, thereby ensuring the stability of the entire vortex mixer, so that the vortex mixer can still maintain stability and safety during high-speed operation.

[0038] In a preferred embodiment, at least four dampers 12 are provided. By providing a plurality of dampers 12, the vibration generated during the operation of the equipment can be effectively reduced. The dampers 12 absorb and disperse the power transmission, thereby reducing the impact of vibration on the overall structure and ensuring that the mixer can operate more smoothly.

[0039] In a preferred embodiment, as Figure 5 shown, four dampers 12 are provided, and the four dampers 12 are respectively arranged at the front, rear, left and right positions of the central plate 10. And, the dampers 12 on the left and right sides are symmetrically distributed, and the dampers 12 on the front and rear sides are symmetrically distributed. Through this design, the applied force can be evenly distributed. This design ensures that the equipment can maintain good balance during operation, reduce offset and vibration, thereby ensuring the stability and safety of the operation. By providing the dampers 12 at the front, rear, left and right, the equipment can more effectively suppress the vibration fluctuations in all directions. The function of the damper 12 is to absorb and reduce the reverse transmission of vibration.

[0040] In a preferred embodiment, as Figure 4As shown, the damper 12 is inclined. One end of the damper 12 is hinged to the bottom plate 14, and the other end is hinged to the central plate 10. The inclined damper 12 can generate feedback for vibrations in both the lateral and longitudinal directions. That is to say, the inclined damper 12 can effectively absorb and respond to vibrations from various directions at multiple angles. This multi-directional feedback ability significantly improves the adaptability of the device in the face of complex vibration conditions and can quickly and effectively handle various external disturbances. The inclined damper 12 can quickly absorb energy when vibration occurs, thereby reducing the transmission of vibration to the central plate 10. This characteristic helps to protect the central plate 10 from the influence of vibration, so that the whole mixer is not easily displaced.

[0041] In a preferred embodiment, at least four first springs 13 are provided. Further optimized, five first springs 13 are provided. The five first springs 13 are respectively arranged at the positions near the four corners of the central plate 10 and the middle position of the central plate 10. The springs arranged at the four corner positions can effectively disperse the external loads from different directions, ensuring uniform force distribution on the central plate 10. The spring at the middle position further enhances the overall load support ability, making the force on the system more balanced in all directions. The combined structure of the five springs can significantly improve the overall rigidity of the system. Under dynamic conditions, the springs can work in coordination with each other. In cooperation with the damper 12, they can effectively cancel vibrations and reduce the displacement of the central plate 10, thereby improving the overall stability of the mixer and ensuring the reliable operation of the mixer.

[0042] In a preferred embodiment, as Figure 5 shown, angle plates 15 are fixedly connected to the positions of the four corners of the central plate 10. A second spring 8 is connected between the angle plate 15 and the support portion 7. The two ends of the second spring 8 are respectively connected to the support portion 7 and the angle plate 15. The design of the angle plate 15 and the second spring 8 is to cope with vibrations in the lateral direction. Through the cooperation of the second spring 8 and the damper 12, the vibration generated by the central plate 10 in the lateral direction can be effectively reduced. At the same time, the design of the angle plate 15 and the second spring 8 also significantly improves the stability of the central plate 10. By reducing the vibration generated in the lateral direction, the displacement of the central plate 10 can be more effectively prevented, ensuring the working stability of the mixer.

[0043] In a preferred embodiment, as Figure 6 and Figure 7As shown in the figure, a connecting device is connected to the connector 2. The connecting device includes a terminal 22, a support rod 20, and a test tube sleeve 19. Among them, the terminal 22 is connected to the connector 2. An articulated seat 17 is fixedly connected to the top of the terminal 22. Rotating rods 21 are fixedly connected to both sides of the bottom of the support rod 20. The rotating rods 21 are rotatably connected to the articulated seat 17. The rotating rod 21 on one side of the support rod 20 penetrates through the articulated seat 17 and extends outside the articulated seat 17. External threads are provided on the side of the rotating rod 21 extending outside the articulated seat 17. A locking nut 16 is connected to the rotating rod 21 through the external threads. The test tube sleeve 19 is sleeved on one side of the support rod 20 close to the top. A number of insertion holes 18 are provided on the test tube sleeve 19. Specifically, during use, the terminal 22 is fixedly connected to the connector 2. The test tube is inserted into the insertion holes 18 on the test tube sleeve 19. The body 1 generates vortex vibration and transmits the vibration to the terminal 22 through the connector 2, and then transmits it to the support rod 20 through the terminal 22, so that the test tube in the test tube sleeve 19 vibrates, and the substances in the test tube are mixed evenly. The traditional mixer can only place the test tube along the axis direction of the connector 2, so there is a problem that the test tube cannot vibrate horizontally. Through this design, during use, loosen the locking nut 16, and the connector 2 can rotate around the articulated seat 17 to adjust the position. After adjusting the position, tighten the locking nut 16. After rotating the support rod 20 by a certain angle, horizontal vibration of the test tube can be achieved, thereby improving the mixing effect. It should be noted here that to prevent the locking nut 16 from loosening during vibration, the inclination direction of the support rod 20 should be opposite to the rotation direction when the locking nut 16 is tightened, so that the support rod 20 can maintain a locked relationship with the locking nut 16 during vibration. At the same time, it should also be noted that during use, the operator needs to hold the support rod 20 by hand. On the one hand, it is to prevent the locking nut 16 from loosening, and on the other hand, it is to prevent the test tube from accidentally falling out of the test tube sleeve 19.
