[0002] Oily sludge refers to sludge mixed with heavy oils such as crude oil, various refined oils, and residual oils. Oily sludge does not exist inherently in nature, but is caused by various industrial, civil, and personal activities related to crude oil and refined oils during oilfield exploitation, petroleum refining processes, transportation, use, storage, etc. Due to various accidents, improper operations, old equipment, damage, corrosion, etc., crude oil and refined oils run, leak, drip, and spill onto the ground, deposit in the ocean, lakes, and river bottoms, and mix with soil, water, etc. to form a mixture of oil, soil, water, and even other pollutants. Oily sludge is harmful to humans, plants, and aquatic organisms.

[0025] Stirring mechanism 5: It includes a rotating column 52, stirring blades 54 and a U-shaped scraper 59. The upper end of the rotating column 52 is rotatably connected to the top wall of the stirring barrel 2. Uniformly distributed stirring blades 54 are provided on the outside of the rotating column 52. The lower end of the rotating column 52 is fixedly connected with a U-shaped scraper 59.

The stirring mechanism 5 further includes a first motor 51. The first motor 51 is arranged at the upper end of the stirring barrel 2. The lower end of the output shaft of the first motor 51 is fixedly connected with the upper end of the rotating column 52. The input end of the first motor 51 is electrically connected to the output end of the control switch group 14. When separating oil from oily sludge, first, the oily sludge is injected into the inside of the stirring barrel 2 through the sludge inlet groove 12, and then the dissolving agent is injected into the inside of the stirring barrel 2 through the water pipe 13. Then, by adjusting the control switch group 14, the heating wire 4 and the first motor 51 operate simultaneously. When the first motor 51 operates, the output shaft of the first motor 51 drives the rotating column 52 to rotate. The rotation of the rotating column 52 drives the stirring blades 54 to rotate, so as to stir and mix the oily sludge and the dissolving agent inside the stirring barrel 2. In order to make the mixing effect of the oily sludge and the dissolving agent better, when the rotating column 52 rotates, the rotating column 52 drives the connecting rod 53 to rotate. The rotation of the connecting rod 53 makes the gears 57 at both ends meshed with the internal gear ring 58, so as to make the two gears 57 rotate.

The rotation of the stirring rods 56 will stir the edge inside the stirring barrel 2, so as to obtain a better mixing effect of the oily sludge and the dissolving agent inside the stirring barrel 2. While the oily sludge and the dissolving agent are mixed, by adjusting the control switch group 14, the heating wire 4 operates. The heating wire 4 will heat the stirring barrel 2, so that the oily sludge inside the stirring barrel 2 can be quickly dissolved, so that the sludge and the dissolving agent are efficiently mixed, and the oil can be dissolved by the dissolving agent, so as to separate from the sludge, and the sludge and the oil can be effectively separated.

[0026] The working principle of an oily sludge separation and treatment device provided by the utility model is as follows: When separating oily sludge, first, the oily sludge is injected into the interior of the stirring barrel 2 through the sludge inlet trough 12. Then, the dissolving agent is injected into the interior of the stirring barrel 2 through the water pipe 13. Next, through the regulation of the control switch group 14, the heating wire 4 and the first motor 51 operate simultaneously. When the first motor 51 operates, the output shaft of the first motor 51 drives the rotating column 52 to rotate. The rotation of the rotating column 52 drives the stirring blades 54 to rotate, thereby stirring and mixing the oily sludge and the dissolving agent inside the stirring barrel 2. To make the mixing effect of the oily sludge and the dissolving agent better, when the rotating column 52 rotates, the rotating column 52 drives the connecting rod 53 to rotate. The rotation of the connecting rod 53 causes the gears 57 at both ends to be meshed and connected with the internal tooth ring 58, thereby causing the two gears 57 to rotate. The rotation of the gears 57 drives the rotating columns 55 to rotate respectively. The rotation of the rotating columns 55 drives the stirring rods 56 to rotate respectively. The rotation of the stirring rods 56 stirs the edge of the interior of the stirring barrel 2, enabling the oily sludge and the dissolving agent inside the stirring barrel 2 to achieve a better mixing effect. While the oily sludge and the dissolving agent are being mixed, through the regulation of the control switch group 14, the heating wire 4 operates. The heating wire 4 heats the stirring barrel 2, enabling the oily sludge inside the stirring barrel 2 to be quickly dissolved, achieving efficient mixing of the sludge and the dissolving agent, enabling the oil to be dissolved by the dissolving agent, thus separating from the sludge, and effectively separating the sludge and the oil. After dissolution, through the regulation of the control switch group 14, the solenoid valve 6 operates, and the solenoid valve 6 opens. The sludge and the oily dissolving agent fall into the interior of the storage tank 7. Then, the sludge stays on the upper end of the filter plate 8, and the sludge and the oily dissolving agent flow down to the lower end of the filter plate 8. Finally, the box door 9 is opened to take out the sludge, and the valve is opened, and the oily dissolving agent is discharged through the water pipe 13, and the next step of oil extraction can be carried out.

[0027] It should be noted that for the first motor 51 disclosed in the above embodiments, the first motor 51 can be selected as D180M - O160030B - E. The control switch group 14 is provided with switch buttons corresponding one - to - one with the heating wire 4, the first motor 51, and the solenoid valve 6 for controlling their switching operations.

[0028] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly.
