Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil production, in particular to a filtering device for lubricating oil production. Background Art

[0002] Lubricant production is a multi-step process encompassing raw material selection, base oil refining, additive blending, mixing and processing, filtration and purification, quality testing, and finally, packaging and shipping. During production, the ratio of base oil to additives must be precisely controlled to ensure the lubricant's excellent performance and stability, while also complying with environmental and safety regulations to minimize environmental impact. These meticulous processes ultimately produce high-quality, standard-compliant lubricants for market and user use. Filtering equipment is often required during lubricant production.

[0003] The existing filtering device for lubricating oil production is usually provided with an outer cylinder and a rotating inner cylinder. After the lubricating oil is added to the rotating inner cylinder, it is centrifugally filtered using the filter screen on the cylinder wall of the inner cylinder. The filtered lubricating oil is thrown to the inner wall of the inner cylinder and then discharged from the oil drain port. When the lubricating oil is thrown out, the lubricating oil is easy to adhere to the inner wall of the inner cylinder. For a long time, it is easy for too much lubricating oil to adhere to and accumulate on the inner wall of the inner cylinder, causing waste. It is also easy for the lubricating oil to adhere too much and become moldy, which is easy to affect the filtering production of the lubricating oil. For this reason, we propose a filtering device for lubricating oil production. Utility Model Content

[0004] The purpose of the utility model is to provide a filtering device for lubricating oil production, so as to solve the problem of excessive lubricating oil adhering to and accumulating on the inner wall of an inner cylinder proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filtering device for lubricating oil production, comprising an outer shell, an inner cylinder is provided inside the outer shell, a rotating cylinder is provided inside the inner cylinder, a filter is provided on the outer wall of the rotating cylinder, a refueling port is provided on the top of the rotating cylinder, an outer scraper ring is matched with the inner wall of the inner cylinder, a connecting block is fixedly connected to the inner scraper ring, an inner scraper ring matched with the filter is fixedly connected to the side wall of the connecting block, a downward pressure column is fixedly connected to the top of the connecting block, a protective cylinder fixedly connected to the top of the outer shell is provided on the outside of the downward pressure column, a pressing handle is provided on the top of the downward pressure column, and a driving motor is provided at the power input end of the rotating cylinder.

[0006] Preferably, a rotating cover is provided on the top of the fuel filling port, and a vertical pipe that cooperates with the rotating cylinder passes through the top of the rotating cover.

[0007] Preferably, a fixing column is fixedly connected to the side wall of the vertical tube, and a scraping strip is fixedly connected to the side wall of the fixing column.

[0008] Preferably, a concave surface matching the vertical tube is provided inside the rotating cylinder, and a notch is provided at the bottom of the vertical tube.

[0009] Preferably, the pressure column passes through the top of the shell, and a long spring is sleeved on the outside of the pressure column.

[0010] Preferably, the fuel filler port is fitted on the top of the housing, and a bearing is fixedly connected to the outer wall of the fuel filler port.

[0011] Preferably, the side wall of the shell is provided with an oil drain port, and the bottom of the shell is provided with supporting legs.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides an outer scraper ring and an inner scraper ring connected by a connecting block between the inner cylinder and the rotating cylinder. When the pressing handle is pressed downward, the lower pressure column slides downward inside the protective cylinder, so that the outer scraper ring and the inner scraper ring respectively scrape the inner wall of the inner cylinder and the outer wall of the rotating cylinder, so that the lubricating oil attached to the inner wall of the inner cylinder and the outer wall of the rotating cylinder is scraped downward and discharged from the oil drain port, thereby preventing the inner wall of the inner cylinder from being adhered to too much lubricating oil and affecting the normal operation of the filtering device. At the same time, it can reduce the waste caused by the adhesion of lubricating oil and prevent the lubricating oil from being adhered to the inner wall of the inner cylinder for a long time and becoming moldy.

[0014] 2. When the filter device of the present invention completes filtering of the lubricating oil material, the vertical pipe can be rotated inside the rotating drum. At the same time, when the vertical pipe rotates, the scraping bar is rotated on the inner wall of the filter screen through the fixed column, so that the impurities attached to the inner wall of the filter screen are scraped and flow to the concave surface of the rotating drum. Then, the top end of the vertical pipe can be connected to an external slag pump, so that the impurities can enter the vertical pipe through the gap and be extracted, thereby realizing convenient cleaning of the impurities inside the rotating drum, eliminating the trouble of disassembling the rotating drum for cleaning, and increasing the convenience of using the filter device.
