[0026] The top shell 150 has an inner shell 200 inside for sealing and protecting the centrifugal shaft 240. The inner shell 200 has a set of sealing bearings 210 on both the left and right sides for maintaining bidirectional sealing inside the inner shell 200. The sealing effect can be maintained on the left and right sides inside the inner shell 200 by using two sets of sealing bearings 210.
[0027] The inner shell 200 is provided with a set of centrifugal shafts 240 for centrifuging materials. The upper inner side of the support base 140 is provided with a set of centrifugal chambers 250 for fixing the lower end of the inner shell 200.

The inner shaft 230 can be limited to rotate by using the first limiting bearing 190 and the second limiting bearing 220.
[0028] The drive end of the motor 100 and the drive wheel 110 are integrated into one structure. The drive wheel 110 and the driven wheel 120 are connected by a belt. The inner side of the driven wheel 120 is connected and fixed to the outer side of the left end of the inner shaft 230.

[0031] Please see Figures 1-4As the first embodiment of this utility model: In order to solve the problem that liquid leakage may affect the normal operation and performance of the centrifuge, leakage may cause corrosion or damage to the internal components of the centrifuge, thereby affecting its centrifugation effect and stability. In the long run, this may shorten the service life of the centrifuge and increase the frequency of maintenance and replacement of parts. First, the staff first introduces the liquid to be centrifuged into the inner shell 200. Since the inner shell 200 is located inside the top shell 150 and the inner shell 200 has a sealed structure, the liquid to be centrifuged can be effectively prevented from leaking inside the inner shell 200. At the same time, since there is a set of sealing bearings 210 on both the left and right sides of the inner shell 200 to maintain the bidirectional seal inside the inner shell 200, the two sets of sealing bearings 210 can maintain the sealing effect on the left and right sides of the inner shell 200 when the centrifugal shaft 240 rotates, thereby preventing the liquid from leaking out inside the inner shell 200.

Since the driving end of the motor 100 and the driving wheel 110 are an integral structure, the driving wheel 110 and the driven wheel 120 are connected by a belt. The inner side of the driven wheel 120 is connected and fixed to the outer side of the left end of the inner shaft 230. The driving wheel 110 drives the driven wheel 120 and the inner shaft 230 to rotate. When the inner shaft 230 rotates, it can drive the centrifugal shaft 240 to perform centrifugation operations on the liquid. At the same time, a set of pulleys is provided on the right side of the inner shaft 230 for belt connection with the driving end of the reducer 180. When the pulley drives the reducer 180 to run, it can effectively reduce the speed of the motor 100 while increasing the torque of the centrifugal shaft 240, thereby facilitating the centrifugation of liquids with different viscosities.
