Technical Field
[0001] The utility model relates to the technical field of industrial waste oil, in particular to a circulating recovery and filtration device for waste mineral oil. Background Technique
[0002] Waste mineral oil is mineral oil that can no longer be used. It is extracted and refined from petroleum, coal, and oil shale. During the processes of mining, processing, and use, due to the action of external factors, its original physical and chemical properties have changed, and it can no longer be used. Waste mineral oil is oil that has been contaminated by impurities, oxidized, and affected by heat, and has changed its original physical and chemical properties and can no longer be used, so it is replaced. Production enterprises such as oil production plants, combined stations, and oily sludge treatment plants will all produce a small amount of waste mineral oil. These waste mineral oils need to be collected and treated uniformly. The recycled waste mineral oil is mainly liquid waste oil and solid or viscous oily sludge mineral oil. Liquid waste mineral oil is relatively easy to process, while solid or viscous waste mineral oil needs to be pretreated before purification.
[0003] Currently, the filtering and recycling treatment equipment for viscous waste oil often has poor filtering effect, and cannot filter out smaller impurities, organic matters, and moisture in the waste mineral oil, which affects the recycling quality of the waste mineral oil and reduces the use effect of the equipment. Therefore, we propose a circulating recovery and filtration device for waste mineral oil to solve the above problems. Content of the Utility Model
[0004] The purpose of the utility model is to provide a circulating recovery and filtration device for waste mineral oil to solve the problems raised in the above background technique.

The outer surface of the filter box 15 is provided with a connecting box 27, and a plurality of round holes are opened on the inner bottom wall of the connecting box 27. The driving motor 21 drives the filter box 15 to rotate. The rotation of the filter box 15 drives the waste mineral oil in the filter box 15 to rotate. Through centrifugal force, impurities and moisture in the waste mineral oil are filtered into the connecting box 27 through the second filter net 30, and then fall into the transfer box 28 through the round holes in the connecting box 27, and then are discharged through the discharge pipe 29. The bottom of the filter box 15 is provided with connecting columns 16 and a discharge pipe 18, and one end of the discharge pipe 18 extends to the bottom of the recovery box 1. The number of the connecting columns 16 is several, and several connecting columns 16 are arranged at equal intervals in a circle at the bottom of the filter box 15.

The outer surface of the guide pipe 12 is provided with an insertion rod 26 for fixing the positioning rod 24. By providing the positioning rod 24, a scraping plate 25 is provided at one end of the positioning rod 24. When the filter box 15 rotates, the scraping plate 25 can scrape off the viscous mineral oil on the second filter net 30, which can effectively prevent the second filter net 30 from being blocked.

When the waste mineral oil drops onto the first filter screen 10 through the feed pipe 4, the filter rack 9 will press downwards towards the spring 7. Due to the acting force of the spring 7, the first filter screen 10 can vibrate up and down, thereby improving the filtering effect of the first filter screen 10 on the waste mineral oil and preventing the first filter screen 10 from being blocked. After the larger impurities in the waste mineral oil are filtered out by the first filter screen 10, the waste mineral oil will drop down through the diversion hopper 11 and then through the diversion pipe 12 into the filter box 15. Then, the drive motor 21 is started, causing the drive motor 21 to drive the rotating shaft 22 to rotate. The rotation of the rotating shaft 22 drives the driving gear 23 to rotate. The rotation of the driving gear 23 drives the driven gear 14 to rotate. The rotation of the driven gear 14 drives the filter box 15 and the connection box 27 to rotate. Thus, through centrifugal force, the impurities and moisture in the waste mineral oil are filtered into the connection box 27 through the second filter screen 30, and then drop into the transfer box 28 through the round holes in the connection box 27 and are discharged through the discharge pipe 29. The waste mineral oil residue after secondary filtration is discharged outwards through the discharge pipe 18, facilitating subsequent recovery and centralized treatment.
