Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuge cleaning, and particularly relates to a cleaning mechanism for a centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate components in a mixture of liquid and solid particles or liquid and liquid. By using the centrifugal force generated by a high-speed rotating centrifuge drum and cooperating with appropriate filter materials, the liquid phase in the solid-liquid mixture is accelerated and thrown out of the drum, while the solid phase remains in the drum to achieve the separation effect. Or, through the strong centrifugal force generated by the high-speed rotation of the rotor, the sedimentation speed of different specific gravity components in the mixture is accelerated to achieve separation. In the prior art, most of them use a cleaning roller to penetrate into the centrifuge and fit with the inner wall of the centrifuge cylinder for cleaning. However, during the cleaning process, due to the different diameters and heights of the centrifuge cylinders, the cleaning roller cannot meet the cleaning requirements of different centrifuges. Different sizes of cleaning rollers need to be replaced according to the specifications of the centrifuge cylinder, and the working steps are cumbersome, which cannot meet the use requirements. Therefore, the inventor proposes a cleaning mechanism for a centrifuge. Summary of the Utility Model

Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] This specific embodiment is a cleaning mechanism of a centrifuge, and its structural schematic diagram is as Figure 1 shown, including a moving base 1, a support column 3, a drive rod 8 and a cleaning roller 4. A rotating disc 2 is rotatably installed on the upper surface of the moving base 1. The support column 3 is vertically installed on the upper surface of the rotating disc 2. The inside of the support column 3 is a hollow structure, and a sliding inner rod 7 slides into one end far from the rotating disc 2. A drive rod 8 is installed above the sliding inner rod 7. The drive rod 8 is horizontally arranged, and a cleaning roller 4 is rotatably installed below one end of the drive rod 8. The cleaning roller 4 is vertically arranged. A spray pipe 11 is installed at one end of the drive rod 8 close to the cleaning roller 4, and the water outlet direction of the spray pipe 11 faces the cleaning roller 4. A drive shaft 5 is fixed at the center of the upper surface of the cleaning roller 4, and the drive shaft 5 is rotatably installed on the drive rod 8. A first motor 6 is fixed on the upper surface of the drive rod 8.

[0024] Referring to Figure 2 , a rotating groove 10 is provided on the upper surface of the moving base 1, and a second motor 9 is embedded in the rotating groove 10. The second motor 9 is fixedly connected to the center of the bottom of the rotating disc 2.

[0025] Referring to Figure 3 , a mounting block 12 is fixed on the outer side wall of the drive rod 8. The spray pipe 11 is fixedly passed through the mounting block 12, and a transmission hose 13 is connected to the end of the spray pipe 11.

[0026] Referring to Figure 4, the support column 3 is vertically arranged and a lifting cylinder 15 is vertically installed inside it. The telescopic end of the lifting cylinder 15 is fixedly connected to the bottom of the sliding inner rod 7. The sliding inner rod 7 is of an L-shaped structure and has a sliding hole at the upper part for the driving rod 8 to slide through. One end of the driving rod 8 away from the cleaning roller 4 is equipped with a fixing plate 16, and a telescopic cylinder 14 is connected to the fixing plate 16. The other end of the telescopic cylinder 14 is fixedly connected to the outer wall of the sliding inner rod 7.

[0027] Working principle: When in use, first move the mobile base 1 to the side of the centrifuge. Then, the lifting cylinder 15 extends, and the sliding inner rod 7 slides upward along the inside of the support column 3. When the cleaning roller 4 is higher than the centrifuge, at this time, the cleaning roller 4 rises synchronously. Then, the telescopic cylinder 14 contracts, driving the fixing plate 16 to move towards the sliding inner rod 7, and thus the cleaning roller 4 moves closer to the center position of the centrifuge. Then, the lifting cylinder 15 contracts, and the cleaning roller 4 descends. Subsequently, the telescopic cylinder 14 contracts, making the cleaning roller 4 fit against the inner wall of the centrifuge tube inside. The driving motor is started to drive the cleaning roller 4 to rotate. After the cleaning roller 4 has rotational force, it cleans the inner wall of the centrifuge tube. At this time, the cleaning liquid is pumped to the spray pipe 11 through the transfer hose 13, and the spray pipe 11 continuously sprays the cleaning roller 4, so that the outer wall of the cleaning roller 4 is continuously rinsed, flushing away the impurities removed from the inner wall of the centrifuge tube. During the process of the cleaning roller 4 rotating and cleaning, the lifting cylinder 15 can contract to drive the cleaning roller 4 to continuously descend. When the height of the centrifuge tube is relatively high, the working range of the cleaning roller 4 can also be changed. When the second motor 9 is subsequently started to drive the rotating disk 2 to rotate, the cleaning roller 4 rotates. At this time, the telescopic cylinder 14 continuously contracts, driving the driving rod 8 to continuously move towards the cleaning roller 4, so that the cleaning roller 4 can rotate in an arc along the inner wall of the centrifuge tube. After moving half a circle, the telescopic cylinder 14 continuously extends, driving the driving rod 8 to continuously move towards the fixing plate 16, and the cleaning roller 4 moves along the other half of the inner wall of the centrifuge tube. The rotating disk 2 at the bottom can be adjusted accordingly in terms of the rotation direction. The cleaning roller 4 has the function of rotating annularly along the centrifuge tube inside the centrifuge, which can effectively improve the cleaning efficiency and can adapt to the cleaning requirements of centrifuges with different diameters and heights.
