The industry has high requirements on the sanitation level of centrifugal separation equipment, and when the equipment does not carry out production operation, residual liquid in the equipment needs to be cleaned and emptied, so that the cleanliness of the interior of the equipment is ensured, and pollution to the next production is avoided. In the conventional centrifugal separation device, no related emptying device is arranged, and after the centrifugal separation device is cleaned, a small amount of liquid is left in the device due to an internal structure, so that the centrifugal separation device can only be disassembled for cleaning to empty the liquid in the device.
The prior art provides an evacuation structure in which a plug screw is provided at the bottom of a drum of a centrifugal separation apparatus, and after the apparatus has been cleaned, the plug screw is screwed out to thoroughly evacuate the liquid inside the apparatus. However, the structure still needs to remove part of the shell of the centrifugal separation device in the actual operation process, and the problem of complex operation still exists.
In this respect, the present embodiment provides a centrifugal separator drum which is also capable of evacuating the liquid inside it, while also solving the above-mentioned problems.
As shown in fig. 1-4, the invention provides a centrifugal separation drum, which comprises a drum body 4, a drum end cover 1 and a sealing assembly, wherein the drum body 4 is of a hollow structure, the drum body 4 is provided with a separation cavity 41, the drum end cover 1 is fixedly connected with one end of the drum body 4, the drum end cover 1 is provided with a liquid discharge channel, the liquid discharge channel is communicated with the separation cavity 41, the liquid discharge channel is arranged below the separation cavity 41, the sealing assembly is arranged in the liquid discharge channel, the sealing assembly comprises a spring 5 and a sealing block 6, one end of the spring 5 is fixedly connected with the sealing block 6, and the sealing block 6 is configured to: when the centrifugal separation drum rotates, the sealing block 6 blocks the drain channel, through which liquid can drain when the centrifugal separation drum is stopped, since the drain channel is arranged below the separation chamber 41. When the centrifugal separation drum rotates to perform centrifugal separation operation, the centrifugal force received by the sealing block 6 is larger than the elastic force of the spring 5, so that the sealing block 6 can seal the liquid discharge channel, separated liquid is prevented from being discharged from the liquid discharge channel, when the liquid in the centrifugal separation drum needs to be emptied, the sealing block 6 enables the liquid discharge channel to be conducted again under the action of the elastic force of the spring 5, and the liquid can be discharged through the liquid discharge channel without disassembling operation.
Specifically, the drain passage includes a first drain passage 11 and a second drain passage 12 that communicate with each other, the first drain passage 11 communicates with the separation chamber 41, and the closing member is provided in the second drain passage 12. The first drain passage 11 and the second drain passage 12 are preferably arranged vertically. The cross-sectional shape of the first liquid discharge channel 11 is preferably circular, and the cross-sectional shape of the second liquid discharge channel 12 may be circular or square. The shape of the sealing block 6 is consistent with the cross-sectional shape of the second liquid discharge channel 12 and the sealing block 6 can completely block the communication between the first liquid discharge channel 11 and the second liquid discharge channel 12. The first liquid discharge channel 11 is located in the middle of the second liquid discharge channel 12, and the sealing block 6 is located in the second liquid discharge channel 12 and can slide in the second liquid discharge channel 12.
Further, the centrifugal separation drum further comprises a gland 3, and the gland 3 is fixedly connected with the drum end cover 1, preferably by means of bolts.

When the drum body 4 is stationary, the seal block 6 slides in the second drain passage 12 toward the axial direction of the drum end cover 1 by the spring 5 until abutting against the bottom wall of the second drain passage 12. At this time, the sealing block 6 does not block or does not block the first liquid discharge channel 11 completely, and the liquid can be discharged along the first liquid discharge channel 11 and the second liquid discharge channel 12. When the drum body 4 rotates, the sealing block 6 overcomes the elasticity of the compression spring 5 to slide towards the direction of the first liquid discharge channel 11 under the action of centrifugal force, and further compresses the spring 5 until the elasticity of the spring 5 and the centrifugal force reach balance, and at the moment, the sealing block 6 can completely seal the first liquid discharge channel 11 to prevent liquid from entering the second liquid discharge channel 12 and being discharged. The elastic coefficient and specification of the spring 5 can be determined and selected by a person skilled in the art according to actual requirements, so as to ensure that the sealing block 6 can completely seal the first liquid discharge channel 11 when the elastic force and the centrifugal force of the spring 5 reach balance.

The two ends of the spring 5 are fixedly connected with the sealing block 6 and the bottom wall of the second liquid discharge channel 12 respectively, and the connection mode can be welding or screw connection. When the drum body 4 is stationary, the sealing block 6 slides in the second liquid discharge channel 12 towards the axial direction of the drum end cover 1 under the action of the tension of the spring 5 until the spring 5 is in a free state, at this time, the sealing block 6 does not or does not completely block the first liquid discharge channel 11, and liquid can be discharged along the first liquid discharge channel 11 and the second liquid discharge channel 12. When the drum body 4 rotates, the sealing block 6 slides towards the direction of the first liquid discharge channel 11 against the pulling force of the spring 5 under the action of centrifugal force, and further stretches the spring 5 until the pulling force of the spring 5 and the centrifugal force reach balance, and at the moment, the sealing block 6 can completely seal the first liquid discharge channel 11, so that liquid is prevented from entering the second liquid discharge channel 12 and being discharged. The elastic coefficient and specification of the spring 5 can be determined and selected by a person skilled in the art according to actual requirements, so as to ensure that the sealing block 6 can completely seal the first liquid discharge channel 11 when the tension and centrifugal force of the spring 5 reach balance. The sealing block 6 can also completely seal the first liquid discharge channel 11 by adjusting the specification and the size of the sealing block 6, and the centrifugal rotating speed range of the sealing block can be wider.
