Description

Technical Field

[0001] The utility model relates to the field of shock-absorbing chassis, in particular to a shock-absorbing chassis used for a centrifuge. Background Art

[0002] A centrifuge is a device that automatically discharges solid-liquid mixtures. After the material is fed into the drum through a feed pipe, the high-speed rotation generates centrifugal force, which results in subsequent solid-liquid separation. A spiral is also provided inside the drum, and the speed difference between the drum and the spiral is used to push the solid objects toward the discharge port. The drum and the spiral are usually referred to as a drum assembly.

[0003] In the existing centrifuge, since the shock absorber is relatively large, the shock absorber is usually clamped or plugged on the base frame of the centrifuge, or a part of the shock absorber is fixedly connected to the base frame and then clamped or plugged with the rest of the shock absorber; however, during the transportation of the centrifuge, the centrifuge is usually lifted by a crane, and the clamped shock absorber is very easy to fall off, that is, the shock absorber as a whole is difficult to be lifted together with the centrifuge. Therefore, when placing the centrifuge, it is necessary to manually re-place the shock absorber, which is time-consuming, labor-intensive, and unsafe;

[0004] To solve the above problems, after searching, a Chinese patent with the publication number CN218654968U discloses a shock-absorbing chassis for a centrifuge and a centrifuge; the article includes that the upper surface of the chassis body is provided with a bearing portion for supporting a drum assembly, and the lower surface is connected to at least four shock absorbers arranged at intervals;

[0005] Although the above patent can add a connector to detachably connect the shock absorber to the base frame using the connector, that is, change the existing installation method of the shock absorber, ensure that the shock absorber will not be separated from the base frame during the transportation of the centrifuge, and increase the safety during the transportation process; however, the shock absorber is a damping shock absorber, and the initial compression of the spring in the shock absorber is fixed, and it is impossible to flexibly adjust the spring compression according to different application scenarios and load conditions.
