Description

TECHNICAL FIELD

[0001] The utility model relates to centrifuge technical field, concretely is a centrifuge sealing cavity. BACKGROUND

[0002] The sealing cavity of the centrifuge is an important area located inside the centrifuge, mainly used for preventing medium leakage and protecting mechanical parts. The sealing cavity is usually located between the rotor and the casing of the centrifuge, and it includes a series of sealing components such as sealing rings, sealing pads or other sealing devices, which are designed to tightly fit to prevent medium leakage. The sealing components of the sealing cavity are usually made of wear-resistant and corrosion-resistant materials to ensure their durability and reliability.

[0003] For example, the Chinese patent "Sealing structure in centrifuge" with publication number CN218440608U includes a sealing device main body, which includes a lower sealing ring and an upper sealing ring. The upper sealing ring is arranged on the surface of the lower sealing ring. An elastic compression mechanism is arranged at the connection between the lower sealing ring and the upper sealing ring. A fixing mechanism is arranged on the side surface of the lower sealing ring. The elastic assembly includes a groove arranged on the edge of the surface of the upper sealing ring and the lower sealing ring. An elastic pad is fixed on the inner surface of the groove by glue. Two elastic sealing blocks are fixed by glue on the surface of the elastic pad. The end of the elastic sealing block is embedded in the inside of the groove. The elastic sealing block and the upper sealing ring are elastically connected through the elastic pad. The lower sealing ring and the upper sealing ring have the same size.

[0004] Although the above-mentioned prior art can achieve the sealing of the centrifuge, in actual use, on the one hand, the noise generated by the centrifuge is difficult to handle. The noise generated during the operation of the centrifuge is transmitted to the outside through the sealing tank, which causes the operating personnel to be exposed to the noise environment for a long time, thereby threatening the health of the operating personnel. On the other hand, the opening and closing of the sealing tank are not flexible enough. When opening or closing the sealing tank, the fixed buckle needs to be removed and installed, which makes the steps of opening and closing the sealing tank cumbersome, thereby reducing the efficiency of the centrifugal operation. Therefore, it does not meet the existing needs. To solve this problem, we propose a centrifuge sealing cavity. UTILITY MODEL CONTENTS

[0015] Preferably, the lower end of the base is provided with a support rod at four corner positions, and the support rod is fixedly connected with the base.

[0016] Compared with the prior art, the present application has the advantages of:

[0017] 1. This utility model uses a placement hook and a fixing hook to install and fix the annular sound insulation cotton. When installing the annular sound insulation cotton, first align the annular sound insulation cotton with the opening of the sealed container and push it into the inside of the sealed container. At this time, the lower end of the annular sound insulation cotton first squeezes the fixing hook, causing the fixing hook to rotate and turn into the storage groove. At the same time, the torsion spring is in a compressed state. Then, continue to push the annular sound insulation cotton downward so that the annular sound insulation cotton contacts and squeezes the placement hook. At this time, the placement hook moves downward while the first spring is compressed. After moving to the appropriate position, the force generated by the torsion spring reset drives the fixing hook inside the storage groove to return to its original position. At this time, the force generated by the first spring reset pushes the placement hook and the annular sound insulation cotton upward together until the fixing hook fixes the annular sound insulation cotton, preventing the noise generated in the centrifuge chamber from being transmitted to the outside, thereby protecting the health of the operators.

[0018] 2. This utility model, through its limiting cavity and arc-shaped limiting block, allows for quick assembly and disassembly of the can lid. To open the lid, first rotate the handle. The arc-shaped limiting block on the lid rotates within the limiting cavity until it aligns with the arc-shaped slot. Then, pull the lid upwards to open the sealed can. To close the can, align the arc-shaped limiting block on the lid with the opening of the arc-shaped slot and push it into the slot. Then, rotate the lid again, causing the arc-shaped limiting block to slide into the limiting cavity. The can lid is then secured by the engagement between the arc-shaped limiting block and the limiting cavity, simplifying the assembly and disassembly process and improving the efficiency of centrifugal operations.

[0019] 3. This utility model uses a damper and a second spring to absorb the vibration generated by the centrifuge during operation. When the centrifuge is working, the rotor inside the motor rotates. The vibration generated by the rotor is transmitted to the base through the motor housing. The vibration generated on the base compresses the damper and the second spring, causing them to deform. During the deformation process, the damper and the second spring absorb the vibration on the base until the vibration weakens or diminishes. At this time, the damper and the second spring reset, and during the reset process, the sealing tank returns to its original position, preventing the vibration generated by the rotor from being transmitted to the sealing tank, which could cause the sealing tank to fail or reduce its sealing performance.
