The closed parts assembly is then installed on bracket one through the relationship between limiting shaft one and groove one. Then, the hoist hook on the hoist can be hooked onto the two connecting ropes. Then, the hoist can be started to separate the outer drum assembly from the inner drum assembly. The separated inner drum assembly will fall onto the collection tray, which can fix the centrifuge drum on the support part, providing support for the hoist's winding force. Moreover, the operation is simple and can save workers a lot of time and energy. Non-manual force can also prevent workers from being injured by extracting the inner cavity.

[0035] 2. By setting up a connecting part, when the hoist winch separates the outer cylinder assembly and the inner cylinder assembly, the force of the hoist winch will pull the inner cavity out of the drum through the connecting rope and the perforated connecting block. At this time, under the action of the groove three, the slider will slide into the grooved connecting block, and the spring extension rod will generate elastic force. At this time, the grooved connecting block can be pulled out of the drum along with the inner cavity. When not separated, the drum will squeeze the sealing ring, causing the spring to undergo elastic deformation and generate elastic force. Under the action of this elastic force, the sealing ring will fit tightly with the drum, and the sealing ring can deepen the sealing effect, making it easier to pull out the inner cavity. At the same time, it can also prevent the sealing performance of the device from being affected by the setting of the connecting part. Attached Figure Description
