Description

Technical Field

[0001] This utility model relates to the field of centrifugation device technology, and in particular to a bovine serum centrifugation extraction device. Background Technology

[0002] The bovine serum centrifugal extraction device was developed to meet the demand for high-quality bovine serum in biopharmaceutical preparations. Bovine serum is rich in nutrients, hormones, and binding proteins essential for cell growth, making it a key raw material in cell culture, vaccine production, and other fields. Traditional extraction methods may suffer from low efficiency and insufficient purity, making it difficult to meet the needs of large-scale production and research.

[0003] With the development of centrifugation technology, centrifugal extraction devices have gradually become mainstream. These devices generate powerful centrifugal force through high-speed rotation, causing different components in the blood to separate according to their density differences, thereby efficiently extracting serum.

[0004] Existing bovine serum centrifugation extraction devices require a first centrifugation using a low-speed centrifuge and a second centrifugation using a high-speed centrifuge. Because the speed difference between the two centrifugations is too large, a single high-speed or low-speed centrifuge cannot fully cover the speed range of the two centrifugations. Therefore, two centrifuges are required to work together during the bovine serum centrifugation process, which makes the instrument cost of bovine serum centrifugation extraction relatively high. Utility Model Content

[0005] The purpose of this invention is to provide a bovine serum centrifugation extraction device to overcome the above-mentioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bovine serum centrifugal extraction device, comprising a centrifuge body, a connecting seat rotatably mounted inside the centrifuge, a rotor fixedly mounted on the connecting seat, a motor fixedly mounted at the bottom of the centrifuge body, and a speed-changing mechanism provided between the motor and the connecting seat.

[0007] As a further description of the above technical solution: the speed change mechanism includes a main shaft, a secondary shaft and an output shaft. The main shaft is fixedly connected to the output end of the motor. The secondary shaft is rotatably installed inside the centrifuge body. The output shaft is fixedly installed at the bottom of the connecting seat. A transmission assembly is provided between the main shaft and the secondary shaft. Two gear assemblies are provided between the secondary shaft and the output shaft. A switching unit is provided between the two gear assemblies.

[0008] As a further description of the above technical solution: the transmission assembly includes two transmission gears, which are respectively fixedly mounted on the main shaft and the secondary shaft, and the two transmission gears mesh with each other.

[0009] As a further description of the above technical solution: the gear assembly includes a countershaft gear and a speed gear, the countershaft gear is fixedly mounted on the countershaft, and the speed gear is rotatably mounted on the output shaft.

[0010] As a further description of the above technical solution: the switching unit includes a synchronous gear, the synchronous gear is fixedly mounted on the output shaft, and gear rings are fixedly mounted on the side walls of the two speed gears near the synchronous gear, and a sleeve is slidably mounted on the synchronous gear.

[0011] As a further description of the above technical solution: a connecting ring is rotatably installed on the outer wall of the sleeve, and an electric push rod is fixedly installed inside the centrifuge body, with the output end of the electric push rod fixedly connected to the connecting ring.

[0012] This invention provides a bovine serum centrifugation extraction device. It offers the following advantages: When using this device, bovine serum centrifugation extraction requires initial centrifugation using a low-speed centrifuge followed by a secondary centrifugation using a high-speed centrifuge. Because the speed difference between the two centrifugations is significant, a single high-speed or low-speed centrifuge cannot fully cover the speed range of both centrifugations. Therefore, two centrifuges are needed in conjunction during the bovine serum centrifugation process, resulting in high costs. This device utilizes a speed-changing mechanism to switch the centrifuge's speed range, allowing only one centrifuge to complete both the initial and secondary centrifugation operations in the bovine serum extraction process, thus facilitating bovine serum centrifugation extraction.

[0013] It should be understood that the foregoing general description and the following detailed description are exemplary and illustrative only, and are not intended to limit this disclosure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6 A bovine serum centrifugation extraction device includes a centrifuge body 1, a connecting seat 2 rotatably mounted inside the centrifuge, a rotor 3 fixedly mounted on the connecting seat 2, a motor 4 fixedly mounted at the bottom of the centrifuge body 1, and a speed-changing mechanism between the motor 4 and the connecting seat 2. When using this device, bovine serum centrifugation extraction requires initial centrifugation using a low-speed centrifuge followed by secondary centrifugation using a high-speed centrifuge. Because the speed difference between the two centrifugations is too large, a single high-speed or low-speed centrifuge cannot fully cover the speed range of both centrifugations. Therefore, two centrifuges are needed in conjunction during the bovine serum centrifugation process, resulting in high costs. This device uses a speed-changing mechanism to switch the speed range of the centrifuge, allowing only one centrifuge to complete both the initial and secondary centrifugation operations in the bovine serum extraction process, facilitating bovine serum centrifugation extraction.

[0025] As a preferred embodiment, the speed-changing mechanism includes a main shaft 5, a secondary shaft 6, and an output shaft 7. The main shaft 5 is fixedly connected to the output end of the motor 4. The secondary shaft 6 is rotatably installed inside the centrifuge body 1. The output shaft 7 is fixedly installed at the bottom of the connecting seat 2. A transmission assembly is provided between the main shaft 5 and the secondary shaft 6. Two gear assemblies are provided between the secondary shaft 6 and the output shaft 7. A switching unit is provided between the two gear assemblies. During the use of this device, the motor 4 drives the main shaft 5 to rotate, which in turn drives the secondary shaft 6 to rotate through the transmission assembly. The rotation of the secondary shaft 6 drives the output shaft 7 to rotate through the gear assemblies. Different gear assemblies have different speed ratios between the secondary shaft 6 and the output shaft 7, thereby achieving the purpose of speed switching.

[0026] As a preferred technical solution of this embodiment, the transmission assembly includes two transmission gears 8, which are respectively fixedly mounted on the main shaft 5 and the secondary shaft 6, and mesh with each other. Through the meshing of the two transmission gears 8, the transmission gear 8 on the main shaft 5 transmits power to the secondary shaft 6 through the transmission gear 8 on the secondary shaft 6, thereby driving the secondary shaft 6 to rotate.

[0027] As a preferred technical solution of this embodiment, the gear assembly includes a countershaft gear 9 and a speed gear 10. The countershaft gear 9 is fixedly mounted on the countershaft 6, and the speed gear 10 is rotatably mounted on the output shaft 7. In the two gear assemblies, the speed gear 10 and the countershaft gear 9 have different tooth ratios, and the speed of the output shaft 7 is controlled by the different tooth ratios.

[0028] As a preferred technical solution of this embodiment, the switching unit includes a synchronous gear 11, which is fixedly mounted on the output shaft 7. Two speed gears 10 are fixedly mounted with gear rings 12 on the side walls near the synchronous gear 11. A sleeve 13 is slidably mounted on the synchronous gear 11. In actual use, the two speed gears 10 represent different speeds of the output shaft 7. When the sleeve 13 is slid, the internal teeth of the sleeve 13 are inserted between the two teeth of the gear ring 12, so that the synchronous gear 11 and the speed gear 10 are fixedly connected to form a whole. At this time, when the secondary shaft 6 rotates, the rotating gear fixed together with the synchronous gear 11 drives the output shaft 7 to rotate together under the action of its meshing secondary shaft gear 9.

[0029] As a preferred technical solution in this embodiment, a connecting ring 14 is rotatably installed on the outer wall of the sleeve 13, and an electric push rod 15 is fixedly installed inside the centrifuge body 1. The output end of the electric push rod 15 is fixedly connected to the connecting ring 14. During the speed switching process, the electric push rod 15 is controlled by the control panel of the centrifuge body 1 to drive the connecting ring 14 and the sleeve 13 to move up and down, so that the synchronous gear 11 can selectively connect between the two speed gears 10, thereby changing the speed range of the centrifuge rotor 3.

[0030] The general working principle of the speed change mechanism:

[0031] Both speed gears 10 are rotatably mounted on the output shaft 7. Therefore, when the secondary shaft 6 rotates, the secondary shaft gear 9 drives the speed gear 10 to rotate without affecting the operation of the output shaft 7.

[0032] During rotational transformation, the internal teeth of the sleeve 13 are inserted between two adjacent teeth of the gear ring 12. Through the meshing between the internal teeth of the sleeve 13 and the teeth of the gear ring 12, the rotation of the speed gear 10 causes the sleeve 13 to rotate. The sleeve 13 is slidably mounted on the synchronous gear 11. Therefore, the rotation of the sleeve 13 causes the synchronous gear 11 to rotate. The synchronous gear 11 is fixedly connected to the output shaft 7. Therefore, the rotation of the gear causes the output shaft 7 to rotate.

[0033] This device is equipped with two gear assemblies. The gear ratio between the countershaft gear 9 and the meshing speed gear 10 of the two gear assemblies is different. The different gear ratios result in different output speed ranges of the output shaft 7, which can be adapted to the primary and secondary centrifugation processes in bovine serum centrifugation.
