Description

Technical Field

[0001] This utility model relates to the field of centrifuge vibration reduction technology, specifically a centrifuge with vibration reduction function. Background Technology

[0002] Centrifuges are devices that use centrifugal force to separate components of different densities in a mixture. They are widely used in fields such as biology, chemical engineering, and medicine. Their core principle is to generate strong centrifugal force through high-speed rotation, causing denser substances to settle to the bottom of the centrifuge tube, thus achieving solid-liquid or liquid-liquid separation. According to the rotation speed, centrifuges can be divided into low-speed, high-speed, and ultra-speed centrifuges. Different types are suitable for separating substances of different sizes, such as cells, proteins, and nucleic acids.

[0003] The working process of a centrifuge includes sample loading, operation and separation, and sampling after shutdown. During the start-up and high-speed rotation stages after sample loading, if the sample volume in the centrifuge tube is uneven, the sample is not placed symmetrically, or the rotor itself has a slight imbalance, a huge centrifugal force deviation will be generated during high-speed rotation, causing the equipment to vibrate violently.

[0004] Existing centrifuges may experience severe vibrations due to centrifugal force deviations when centrifuging samples, which can directly affect the stability and separation accuracy of the centrifuge.

[0005] Therefore, a centrifuge with shock absorption function is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A centrifuge with shock absorption function, comprising a workbench with a cover plate hinged to the top; a chamber inside the workbench; a centrifuge inner liner inside the workbench; a first motor fixed to the inner wall of the chamber; a main shaft fixed to the output end of the first motor; the main shaft and the workbench being rotatably connected; the main shaft located inside the centrifuge inner liner; a rotor fixed to the end of the main shaft; a shock-absorbing ring fixed between the main shaft and the rotor; multiple centrifuge tube holes opened inside the rotor; a rubber anti-vibration pad fixed to the bottom of the workbench; and a control console fixed to the side wall of the workbench. By adding a shock-absorbing ring, the vibration generated when the main shaft drives the rotor to rotate can be reduced, thereby reducing the occurrence of deviations in separation accuracy or even damage to core components caused by unbalanced forces due to slight differences in sample distribution or minor wear, which can lead to severe vibration of the equipment.

[0008] Preferably, a guide plate is fixedly connected to the top of the rotor; a guide ring is fixedly connected to the side wall of the guide plate; by adding a guide ring, it is easier to insert the solution to be centrifuged into the centrifuge tube hole, reducing the occurrence of test tube damage due to inaccurate insertion. At the same time, adding a guide plate can better and more accurately insert the test tube.

[0009] Preferably, the centrifuge tube hole is provided with multiple friction blocks; by adding friction blocks, the friction on the solution test tube can be increased after the solution test tube is inserted into the centrifuge tube hole, which can reduce the vibration of the solution test tube caused by centrifugation, or even the situation of the solution test tube being thrown out.

[0010] Preferably, the workbench is provided with multiple heat dissipation vents; a cooling fan is fixedly connected to the side wall of the chamber; multiple air inlets are provided on the side wall of the cooling fan; a second motor is provided at the input end of the cooling fan; a rotating shaft is fixedly connected to the output end of the second motor; multiple fan blades are fixedly connected to the middle of the rotating shaft; by adding a cooling fan, the accumulation of heat generated by centrifugation inside the centrifuge can be reduced, which could lead to the denaturation of the solution in the test tube.

[0011] Preferably, multiple support plates are fixedly connected inside the chamber; a damper is installed inside the support plate; a C-shaped clamp is fixedly connected to the top of the support plate; a spring is provided on the outer wall of the damper; and an elastic pressure plate is fixedly connected to the end of the damper. By adding the elastic pressure plate, the vibration generated by the first motor when driving the main shaft to rotate can be reduced, thereby aggravating the vibration of the main body, which may lead to deviations in separation accuracy or even damage to core components.

[0012] Preferably, the side wall of the workbench is provided with an observation port; a baffle plate is hinged to the top of the observation port; by adding an observation port, the degree of separation of the solution can be directly observed by opening and closing the baffle plate, reducing the complexity of solution observation.

[0013] The advantages of this utility model are: 1. The centrifuge with shock absorption function described in this utility model can reduce the vibration generated when the main shaft drives the rotor to rotate by adding shock absorption rings. This reduces the unbalanced forces caused by slight differences in sample distribution, minor wear, etc., which can lead to deviations in separation accuracy or even damage to core components due to severe vibration of the equipment.

[0014] 2. The centrifuge with shock absorption function described in this utility model can more conveniently insert the solution to be centrifuged into the centrifuge tube hole by adding a guide ring, reducing the occurrence of test tube damage due to inaccurate insertion. At the same time, the addition of a guide plate can better and more accurately insert the test tube. Attached Figure Description

A control console 13 is fixed to the side wall of the workbench 1. Push the cover plate 11 upwards, and then place the solution test tube to be centrifuged into the centrifuge tube hole 19 through the guide ring 2. Then start the control console 13, which will start the first motor 16. The first motor 16 will drive the spindle 17 to rotate, and the spindle 17 will drive the shock-absorbing ring 15 to rotate. The shock-absorbing ring 15 will then drive the rotor 18 to rotate together. By adding the shock-absorbing ring 15, the vibration generated when the spindle 17 drives the rotor 18 to rotate can be reduced. This reduces the unbalanced force caused by slight differences in sample distribution, slight wear, etc., which can lead to severe vibration of the equipment and deviation in separation accuracy, or even damage to core components.

[0021] like Figures 3 to 4 As shown, a guide plate 21 is fixedly connected to the top of the rotor 18; a guide ring 2 is fixedly connected to the side wall of the guide plate 21; when the solution test tube is placed inside the guide ring 2, the solution test tube will then enter the centrifuge tube hole 19 through the guide plate 21; by adding the guide ring 2, it is easier to insert the solution to be centrifuged into the centrifuge tube hole 19, reducing the occurrence of test tube damage due to inaccurate insertion. At the same time, adding the guide plate 21 can better and more accurately insert the test tube.

[0022] like Figure 4 As shown, multiple friction blocks 3 are provided inside the centrifuge tube hole 19. After the solution tube passes through the guide ring 2, the solution tube will enter the centrifuge tube hole 19 through the guide plate 21, and then the friction blocks 3 will come into contact with the solution tube. By adding friction blocks 3, the friction on the solution tube can be increased after the solution tube is inserted into the centrifuge tube hole 19, which can reduce the vibration of the solution tube caused by centrifugation, or even the situation of it being thrown out.

The rotating shaft 42 then drives the fan blades 43 to rotate, and the heat enters the cooling fan 4 through the air inlets 44 and is then discharged. By adding a cooling fan 4, the accumulation of heat generated by centrifugation inside the centrifuge can be reduced, which could lead to the denaturation of the solution in the test tube.

Then the spring 54 will extend and retract simultaneously with the damper 53. By adding the elastic pressure plate 5, the vibration generated by the first motor 16 when driving the main shaft 17 to rotate can be reduced, thereby aggravating the vibration of the main body, which may lead to deviations in separation accuracy or even damage to core components.

[0025] like Figure 2 and Figure 7 As shown, the workbench 1 has an observation port 6 on its side wall; a baffle plate 61 is hinged to the top of the observation port 6; the baffle plate 61 is flipped upwards, and then the baffle plate 61 will move, and then observation can be made through the observation port 6; by adding the observation port 6, the degree of separation of the solution can be directly observed by opening and closing the baffle plate 61, reducing the complexity of solution observation.

[0026] Working principle: Push the cover plate 11 upwards, then place the solution tube to be centrifuged into the centrifuge tube hole 19 through the guide ring 2. Then start the control console 13, which will start the first motor 16. The first motor 16 will drive the main shaft 17 to rotate, which in turn drives the damping ring 15 to rotate. The damping ring 15 will then drive the rotor 18 to rotate together. Place the solution tube inside the guide ring 2, and the solution tube will enter the centrifuge tube hole 19 through the guide plate 21. After the solution tube passes through the guide ring 2, it will enter the centrifuge tube hole 19 through the guide plate 21. Then the friction block 3 will contact the solution tube, and the first motor 16 will drive the main shaft 17 to rotate. The heat generated during rotation enters the bottom of the worktable 1 through the heat dissipation vent 45. Then, the second motor 41 is started, which drives the rotating shaft 42 to rotate.

At this time, the elastic pressure plate 5 will contact the first motor 16, and the damper 53 will extend and retract. Then, the spring 54 will extend and retract simultaneously with the damper 53, flipping the baffle 61 upward. The baffle 61 will then move, and observation can be made through the observation port 6.
