Description

Technical Field

[0001] This utility model relates to the technical field of solid-liquid separation devices for lubricating oil raw materials, specifically a centrifuge for lubricating oil processing. Background Technology

[0002] Lubricating oil is a lubricating medium used to reduce friction, wear, cool, and clean mechanical parts. It is widely used in automobiles, industrial equipment, aerospace, and other fields.

[0003] Currently, in the production process of lubricating oil, solid-liquid separation devices are needed to separate solid impurities from liquid raw materials. However, commonly used solid-liquid separation devices have low working efficiency and are not convenient for cleaning solid impurities. For example, CN210545737U discloses a solid-liquid separation device for lubricating oil production, which includes a processing tank, a centrifuge, a sedimentation tank and an oil collection tank. The top of the processing tank is provided with a feed inlet, the upper left side of the inside of the processing tank is provided with a centrifuge, the bottom of the centrifuge is provided with a sedimentation tank, and the bottom of the centrifuge is connected to the sedimentation tank through a pipe. A filter screen is fixedly connected to the upper part of the inside of the sedimentation tank by bolts.

[0004] As can be seen from the above-mentioned disclosed scheme, the solid impurities intercepted inside the centrifuge fall onto the surface of the filter screen. The device needs to be opened for cleaning, which is time-consuming and laborious, reducing the convenience of cleaning. In addition, the centrifuge discharges material through the liquid guide pipe, which has low discharge efficiency. At the same time, the material is discharged downwards and then separated again. As a result, the lubricating oil raw material needs to be separated multiple times to complete the solid-liquid separation, which reduces the working efficiency of solid-liquid separation. Utility Model Content

The bottom of the connecting hole is fixedly connected to a solid discharge nozzle, and the surface of the solid discharge nozzle is fixedly connected to a second sealing bearing and a solenoid valve. One end of the solid discharge nozzle is connected to the inside of the rotating cylinder, and the solid impurities filtered inside the rotating cylinder can be directly discharged after the solenoid valve is opened.

The surface of the sewage discharge mechanism 3 is rotatably connected to the bottom of the centrifuge body 1. A liquid discharge nozzle 13 is fixedly connected to the bottom of the centrifuge body 1. An intelligent valve is provided on the surface of the liquid discharge nozzle 13. One end of the liquid discharge nozzle 13 is connected to the lubricating oil liquid raw material storage device, which facilitates the direct storage of the liquid raw material after solid-liquid separation.

[0023] The sewage discharge mechanism 3 includes a support plate 31. The surface of the support plate 31 is provided with an arc-shaped groove 32. The bottom of the arc-shaped groove 32 has a connecting hole 33. The bottom of the connecting hole 33 is fixedly connected to a solid discharge nozzle 35.

The surface of the solid discharge nozzle 35 is fixedly connected to a second sealing bearing 36 and a solenoid valve 37.

[0025] The working principle of this device is as follows: During operation, the motor 14 starts, causing the drive gear 15 to rotate. The rotation of the drive gear 15 drives the driven gear 27 to rotate, which in turn drives the rotating tube 26 to rotate. The rotation of the rotating tube 26 drives the rotating cylinder 21 to rotate, which in turn drives the support plate 31 to rotate. The rotation of the support plate 31 drives the solid discharge nozzle 35 to rotate. Then, the valves of the feeding pipe 29 and the liquid discharge nozzle 13 are opened. At this time, the raw material to be separated enters the rotating tube 26 through the feeding pipe 29 and then enters the rotating cylinder 21. After entering the rotating cylinder 21, the liquid raw material is discharged by centrifugal force. The separated liquid raw material is then transported to the liquid raw material storage device for storage through the liquid discharge nozzle 13. The separated solid impurities are intercepted in the rotating cylinder 21. When it is necessary to clean the solid impurities in the rotating cylinder 21, the solenoid valve 37 can be opened, allowing the solid impurities in the rotating cylinder 21 to enter the connecting hole 33 through the bottom hole 23, and then enter the solid discharge nozzle 35 through the connecting hole 33, and finally be discharged into the solid impurity collection device.
