[0026] like Figures 1 to 5 As shown, the solid-liquid separation device includes a base 1, an outer barrel 2 fixedly mounted on the top of the base 1, a drain pipe 21 located on one side of the bottom of the outer barrel 2, and a barrel cover 3 mounted on the top of the outer barrel 2. One end of the barrel cover 3 is hinged to the outer barrel 2 via a hinge 32, and the other end of the barrel cover 3 is detachably connected to the outer barrel 2 via a buckle 31. A centrifuge rack 4 is rotatably mounted inside the outer barrel 2, and a rotary drive component 8 for driving the centrifuge rack 4 is located inside the base 1. A centrifuge barrel 5 is movably inserted into the centrifuge rack 4 along the axial direction of the outer barrel 2. Filter holes 54 are evenly distributed on the side of the centrifuge barrel 5. In this embodiment, the centrifuge barrel 5 is inserted inside the centrifuge rack 4. The solid-liquid mixture is filled into the centrifuge tank 5. The rotation drive component 8 is activated to drive the centrifuge frame 4 to rotate. The centrifuge frame 4 drives the centrifuge tank 5 to rotate. Under the action of centrifugal force, the liquid inside the centrifuge tank 5 is thrown out through the filter hole 54, while the solid remains inside the centrifuge tank 5, thus achieving solid-liquid separation. After the solid-liquid separation is completed, the centrifuge tank 5 can be pulled upward from inside the centrifuge frame 4. After the centrifuge tank 5 is removed, the solids inside can be poured out directly, making it convenient to remove the material. Then, the centrifuge tank 5 can be easily cleaned and disinfected for the next use. The centrifuge tank 5 is prone to damage during use. After damage, it can be easily removed and replaced separately, improving the convenience of maintenance.

[0027] In some embodiments, the outer side of the centrifuge tank 5 has positioning strips 51 arranged in a circular array; the centrifuge frame 4 has a turntable 43 rotatably disposed at the bottom of the inner side of the outer tank 2, a lower support frame 42 is fixedly disposed on the top of the turntable 43, and an upper support frame 41 is fixedly mounted above the lower support frame 42 by a support rod, and the inner sides of both the upper support frame 41 and the lower support frame 42 have positioning grooves 44 that match the positioning strips 51; the centrifuge tank 5 and the centrifuge frame 4 are connected by the positioning strips 51 and the positioning grooves 44 to achieve positioning between the centrifuge tank 5 and the centrifuge frame 4, and to prevent slippage between the centrifuge tank 5 and the centrifuge frame 4 when the centrifuge frame 4 rotates; wherein the support rod is a rod-shaped structure arranged in a circular array on the top of the lower support frame 42, and the upper support frame 41 is fixed to the upper end of the support rod.

[0028] In some embodiments, a retaining edge 53 is provided on the outer side of the top of the centrifuge bucket 5, and the retaining edge 53 abuts against the top of the upper support frame 41; when the centrifuge bucket 5 is installed inside the centrifuge frame 4, the retaining edge 53 abuts against the top of the upper support frame 41.

[0029] In some embodiments, the outer side of the baffle 53 is provided with a circular array of handplates 52, which are integral with the baffle 53. By pressing the handplates 52, the centrifuge bucket 5 can be easily pulled out from inside the centrifuge rack 4.

[0030] In some embodiments, a pressure plate 6 corresponding to the top of the centrifuge tank 5 is rotatably provided on the inner side of the lid 3. The pressure plate 6 coincides with the rotation axis of the centrifuge frame 4. After the lid 3 is closed, the pressure plate 6 presses against the top of the centrifuge tank 5 and limits its position at the top of the centrifuge tank 5. At the same time, the pressure plate 6 can rotate with the centrifuge tank 5 to improve the stability of the centrifuge tank 5 during rotation. Specifically, a rotating shaft is provided in the center of the top of the pressure plate 6. The rotating shaft is rotatably connected to the bottom of the lid 3 through a bearing.

[0031] In some embodiments, an elastic plate 7 is fixedly provided at the bottom of the pressure plate 6. The elastic plate 7 can increase the friction between the pressure plate 6 and the upper end of the centrifuge tank 5. On the other hand, after the tank lid 3 is closed, the elastic plate 7 undergoes elastic deformation. Through the elastic force of the elastic plate 7 and the top of the centrifuge tank 5, the stability of the centrifuge tank 5 during rotation is ensured. Specifically, the elastic plate 7 is a rubber plate or a silicone plate.

[0032] In some embodiments, the top of the base 1 has at least four adjustable feet 11 arranged in a circular array. The adjustable feet 11 can be used to adjust the solid-liquid separation device to a horizontal state to prevent shaking during operation.

[0033] In some embodiments, the rotary drive component 8 is a variable frequency motor.
