Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and specifically to a centrifuge. Background Technology

[0002] Centrifugation is a physical method that uses a centrifugal force field to separate or concentrate substances with different densities. In many fields, such as chemical engineering, biomedicine, and food processing, centrifuges play an indispensable role as key equipment for centrifugal operations. For example, in the biomedical field, centrifugation can separate blood cells and plasma for research on blood components and clinical diagnosis; in the chemical industry, centrifuges can be used to separate liquids or solid particles of different densities, achieving material purification and recovery.

[0003] Currently, most centrifuges employ a single rotation method, meaning the container only revolves around a central point. While this single rotation mode can achieve material separation to some extent, it has significant limitations in centrifugation efficiency. When the container only revolves, the movement trajectory of the material within the container is relatively simple, and some material may form a relatively stable laminar flow region near the inner wall of the container, preventing the centrifugal force from fully acting on all materials. This not only prolongs centrifugation time but may also affect the separation effect, making it difficult to completely separate substances with similar densities, resulting in low centrifugation efficiency. Utility Model Content

[0004] Therefore, this utility model provides a centrifuge to solve the problems existing in the above-mentioned technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A centrifuge, comprising:

[0007] Mounting base, the mounting base being used to connect to the centrifuge body;

[0008] The bearing housing is vertically and fixedly connected to the bottom of the mounting base;

[0009] A drive shaft passes through the bearing housing and the mounting base, and is rotatably connected to the bearing housing and the mounting base. The top end of the drive shaft is higher than the top end of the mounting base.

[0010] A rotating seat is disposed on the top of the transmission shaft and is fixedly connected to the transmission shaft;

[0011] Follower blocks, two follower blocks are provided, the two follower blocks are provided at both ends of the rotating seat, and the follower blocks are set at an angle to the rotating seat;

[0012] A rotating disk is disposed on the follower block and is rotatably connected to the follower block. A follower shaft is fixedly inserted at the axis of the rotating disk.

[0013] The transmission mechanism connects the follower shaft and the transmission shaft, allowing the follower shaft and the transmission shaft to rotate synchronously.

[0014] Optionally, the transmission mechanism includes a first bevel gear, which is sleeved on the transmission shaft and fixedly connected to the mounting base. The first bevel gear is rotatably connected to the transmission shaft. A second bevel gear is meshed on each side of the first bevel gear in the horizontal direction. The second bevel gears are rotatably connected to the rotating base. A fourth bevel gear is coaxially fixedly connected to the bottom of the follower shaft. A third bevel gear is meshed on one side of the fourth bevel gear. The third bevel gear is rotatably connected to the rotating base and is coaxially arranged with the second bevel gears. The third bevel gear and the second bevel gears are fixedly connected by a transmission connecting rod.

[0015] Optionally, the included angle between the follower block and the rotating seat is 120°-150°.

[0016] Optionally, a connecting seat is provided on the top of the rotating disk, the connecting seat is fixedly connected to the rotating disk, and the surface of the connecting seat is provided with mounting holes. A centrifuge tank is provided on the connecting seat, and the bottom of the centrifuge tank is provided with threaded holes corresponding to the mounting holes on the surface of the connecting seat. The centrifuge tank and the connecting seat are detachably connected by a bolt assembly.

[0017] Optionally, the mounting base is provided with threaded holes for connection and fixation with reserved bolts on the centrifuge body.

[0018] This utility model has at least the following beneficial effects:

[0019] This invention mounts the centrifugal structure onto the centrifuge body using a mounting base, and connects the drive shaft to the motor output shaft inside the centrifuge body, allowing the motor to drive the drive shaft to rotate. A rotating disk is positioned at the center of the follower block, allowing the disk to rotate on the follower block. A follower shaft is fixed to the bottom of the rotating disk and inserted into the follower block, with the follower shaft and follower block rotatably connected. This allows the rotating disk to rotate on the follower block via the follower shaft. The follower shaft is connected to the drive shaft via a transmission mechanism, enabling the drive shaft to drive the rotating base to rotate, which in turn drives the follower shaft and the rotating disk to rotate. This, in turn, drives the centrifuge tank on the rotating disk to rotate, causing the solution tank inside the centrifuge tank to rotate on its own axis while rotating with the rotating base. This achieves the separation of substances with similar densities and improves centrifugation efficiency. Attached Figure Description

[0032] like Figures 1-5 As shown, this utility model discloses a centrifuge, comprising:

[0033] Mounting base 1, which is used to connect the centrifuge body 2;

[0034] Bearing housing 3, which is vertically fixed to the bottom of mounting base 1;

[0035] A drive shaft 4 passes through the bearing housing 3 and the mounting base 1, and is rotatably connected to the bearing housing 3 and the mounting base 1. The top end of the drive shaft 4 is higher than the top end of the mounting base 1.

[0036] Rotary seat 5, which is disposed on the top of the transmission shaft 4 and is fixedly connected to the transmission shaft 4;

[0037] Follower block 6, two follower blocks 6 are provided, the two follower blocks 6 are provided at both ends of the rotating seat 5, and the follower blocks 6 and the rotating seat 5 are arranged at an angle;

[0038] A rotating disk 7 is disposed on the follower block 6 and is rotatably connected to the follower block 6. A follower shaft is fixedly inserted at the axis of the rotating disk 7.

[0039] The transmission mechanism 8 connects the follower shaft and the transmission shaft 4, and the follower shaft and the transmission shaft 4 rotate synchronously.

[0040] The centrifuge body described above is a box structure with an internal mounting frame. The frame is equipped with a support base and bolts. The mounting base 1 has corresponding bolt holes at its corners. By aligning the bolt holes on the mounting base 1 with the bolts on the support base, the mounting base 1 is fixed from its corners and then locked with nuts.

[0041] When mounting base 1 is placed inside the centrifuge body, drive shaft 4 is coaxially and fixedly connected to the output shaft of drive motor inside the centrifuge body, using a keyway insertion method;

[0042] The aforementioned bearing housing 3 serves as a support structure for the drive shaft 4. The bearing housing 3 is fixedly connected to the bottom of the mounting base 1. The drive shaft 4 passes through the bottom of the bearing housing 3. The mounting base 1 has through holes adapted to the bearing housing 3 for mounting and fixing the bearing housing 3. The top end of the drive shaft 4 extends beyond the bearing housing 3 and the top of the mounting base 1. A rotating base 5 is mounted and fixed to the top of the drive shaft 4. The rotating base 5 is a horizontal plate structure. The drive shaft 4 is connected to the center of the rotating base 5. Follower blocks 6 are provided at both ends of the rotating base 5. The follower blocks 6 are rotated by... The two ends of the seat 5 extend obliquely upwards. The follower block 6 and the rotating seat 5 are set at an obtuse angle. A rotating disk 7 is set at the center of the follower block 6. The rotating disk 7 can rotate on the follower block 6. A follower shaft is fixed at the bottom of the rotating disk 7 and is inserted into the follower block 6. The follower shaft and the follower block 6 are rotatably connected, so that the rotating disk 7 can rotate on the follower block 6 through the follower shaft. The follower shaft is connected to the transmission shaft 4 through the transmission mechanism 8, so that while the transmission shaft 4 drives the rotating seat 5 to rotate, it can also drive the follower shaft and the rotating disk 7 to rotate.

[0043] In one specific embodiment, the transmission mechanism 8 includes a first bevel gear 81, which is sleeved on the transmission shaft 4 and fixedly connected to the mounting base 1. The first bevel gear 81 is rotatably connected to the transmission shaft 4. A second bevel gear 82 is meshed on each side of the first bevel gear 81 in the horizontal direction. The second bevel gear 82 is rotatably connected to the rotating base 5. A fourth bevel gear 84 is coaxially fixedly connected to the bottom of the follower shaft. A third bevel gear 83 is meshed on one side of the fourth bevel gear 84. The third bevel gear 83 is rotatably connected to the rotating base 5 and is coaxially arranged with the second bevel gear 82. The third bevel gear 83 and the second bevel gear 82 are fixedly connected by a transmission connecting rod 85.

[0044] The aforementioned transmission mechanism 8 specifically connects the drive shaft 4 and the follower shaft via two sets of rotating bevel gears. The first bevel gear 81 is sleeved on the drive shaft 4, and its bottom is fixedly connected to the mounting base 1. Simultaneously, the first bevel gear 81 is rotatably connected to the drive shaft 4. Two second bevel gears 82 are provided, with their axes horizontally aligned. The second bevel gears 82 mesh with the first bevel gear 81. The rotating base 5 has corresponding grooves for placing the second bevel gears 82, which are rotatably connected to the rotating base 5. A fourth bevel gear 84 is located at the bottom of the follower block 6, and is coaxially fixedly connected to the follower shaft. The fourth bevel gear 84 is rotatably connected to the follower block 6. A third bevel gear 83 meshes with one side of the bottom of the fourth bevel gear 84. The third bevel gear 83 is coaxially arranged with the second bevel gear 82. The third bevel gear 83 is rotatably connected to the end of the rotating seat 5. The second bevel gear 82 and the third bevel gear 83 are connected by a transmission link 85. The two ends of the transmission link 85 are coaxially fixed with the second bevel gear 82 and the third bevel gear 83. As the rotating seat 5 rotates, the second bevel gear 82 will roll (rotate) through the meshing first bevel gear 81. Then, the transmission link 85 drives the third bevel gear 83 to rotate. The third bevel gear 83 then drives the fourth bevel gear 84, which in turn drives the follower shaft and the rotating disk 7 to rotate. By fixing the centrifuge barrel 11 on the rotating disk 7, the centrifuge barrel 11 will rotate on its own axis as the rotating seat 5 drives the centrifuge barrel 11 to rotate, thereby improving the centrifugation efficiency.

[0045] In one specific embodiment, the included angle between the follower block 6 and the rotating seat 5 is 120°-150°.

[0046] The angle between the aforementioned follower block 6 and the rotating seat 5 can be set to 120°-150°, with 135° being the optimal value, so that the angle between the centrifuge bucket 11 and the horizontal plane is 45°.

[0047] In a further embodiment, the centrifuge tank 11 and the rotating disk 7 are specifically connected as follows: a connecting seat 9 is provided on the top of the rotating disk 7, the connecting seat 9 is fixedly connected to the rotating disk 7, and an installation hole 10 is provided on the surface of the connecting seat 9. The centrifuge tank 11 is provided on the connecting seat 9, and a threaded hole corresponding to the installation hole 10 on the surface of the connecting seat 9 is provided on the bottom of the centrifuge tank 11. The centrifuge tank 11 and the connecting seat 9 are detachably connected by a bolt assembly.

[0048] By fixing the connecting seat 9 to the top of the rotating disk 7, the connecting seat 9 rotates together with the rotating disk 7. A ring of threaded holes is set on the connecting seat 9, and then a ring of threaded holes is correspondingly opened on the bottom of the centrifuge bucket 11. After aligning the threaded holes on the bottom of the centrifuge bucket 11 with the threaded holes on the connecting seat 9, the centrifuge bucket 11 can be fixed on the connecting seat 9 by bolts. During centrifugation, the container bucket containing the solution is directly placed into the centrifuge bucket 11. The size of the centrifuge bucket 11 is set to be slightly smaller than the size of the container bucket, and the two are interference fit. Alternatively, the centrifuge bucket 11 and the container bucket can be fixed by bolt connection or other methods. The specific structure will not be described in detail here.

[0049] The above specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0050] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.

[0051] The present invention has been described in a relatively specific and detailed manner above through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, various modifications and improvements can be made to these specific embodiments, all of which fall within the scope of protection of this application. Therefore, the scope of protection of this patent application should be determined by the appended claims.
