[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: an oil sludge extraction device, including an installation base plate 1 and an oil sludge automatic separation device. A extraction tank 2 is fixedly installed on the top of the installation base plate 1. A conical mud inlet cylinder 3 is fixedly connected to the surface of the extraction tank 2. An extraction agent automatic addition tank 4 is provided at the bottom of the conical mud inlet cylinder 3. A rotating shaft 5 is rotatably connected inside the extraction tank 2. A stirring shaft 6 is fixedly connected to the surface of the rotating shaft 5. A spiral rod 7 is fixedly connected to the surface of the stirring shaft 6. The surface of the spiral rod 7 contacts the inner wall of the extraction tank 2. The left end of the rotating shaft 5 extends to the outside of the extraction tank 2. A driving motor 8 is fixedly installed on the top of the installation base plate 1. The output end of the driving motor 8 is fixedly connected to the left end of the rotating shaft 5.

[0025] After the staff adds the oil sludge mixture into the extraction tank 2 from the conical mud inlet cylinder 3 and then pours the extraction agent into the extraction agent automatic addition tank 4, the extraction agent automatic addition tank 4 can automatically add the extraction agent into the extraction tank 2 in a fixed amount to mix it with the oil sludge mixture. After starting the driving motor 8, the output end of the driving motor 8 rotates to drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 first drives the stirring shaft 6 to rotate to stir and mix the extraction agent and the oil sludge mixture, making them evenly mixed, and the extraction agent extracts and separates the oil inside the oil sludge mixture. Then, the rotation of the stirring shaft 6 drives the spiral rod 7 to rotate and gradually moves the oil sludge mixture to the right side inside the extraction tank 2.

[0026] The oil sludge automatic separation device includes an oil sludge separation cylinder 9, a sludge discharge pipe 10, a servo motor 11, an auger 12, a filter cylinder 13 and an oil discharge pipe 14. The oil sludge separation cylinder 9 is fixedly installed at the right end of the extraction tank 2. The sludge discharge pipe 10 is fixedly installed on the surface of the oil sludge separation cylinder 9. The servo motor 11 is fixedly installed on the top of the oil sludge separation cylinder 9.

An oil storage tank 15 is fixedly connected to the top of the installation base plate 1. A sludge storage box 16 is fixedly connected to the right end of the installation base plate 1.

[0027] After the staff operate the automatic servo motor 11, the output end of the servo motor 11 rotates to drive the auger 12 to rotate. The auger 12 gradually conveys the sludge mixture to the top of the sludge separation cylinder 9. During the process that the sludge mixture gradually moves upward inside the sludge separation cylinder 9, the oil on its surface is squeezed and separated through the extrusion with the filter cylinder 13. The liquid oil flows through the filter cylinder 13 to the inner wall of the sludge separation cylinder 9 and is discharged into the interior of the oil storage tank 15 through the drain pipe 14. The separated sludge gradually moves upward through the auger 12 and is discharged into the interior of the sludge storage tank 16 through the sludge discharge pipe 10. At this time, the staff can continuously add the sludge mixture into the extraction tank 2 through the conical sludge inlet cylinder 3 for extraction, and separate the oil and sludge through the sludge separation cylinder 9, thereby realizing the function of extracting while discharging sewage, and improving the extraction efficiency of the sludge mixture.

[0028] Working principle: For this sludge extraction device, after the staff add the sludge mixture into the extraction tank 2 from the conical sludge inlet cylinder 3, the extraction agent automatic addition tank 4 can automatically and quantitatively add the extraction agent into the extraction tank 2 to mix it with the sludge mixture. After starting the drive motor 8, the output end of the drive motor 8 rotates to drive the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 first drives the stirring shaft 6 to rotate to stir and mix the extraction agent and the sludge mixture evenly. While the stirring shaft 6 rotates, it drives the spiral rod 7 to rotate to gradually move the sludge mixture to the right side inside the extraction tank 2. The output end of the servo motor 11 rotates to drive the auger 12 to rotate. The auger 12 gradually conveys the sludge mixture to the top of the sludge separation cylinder 9. During the process that the sludge mixture gradually moves upward inside the sludge separation cylinder 9, the oil on its surface is squeezed and separated through the extrusion with the filter cylinder 13. The liquid oil flows through the filter cylinder 13 to the inner wall of the sludge separation cylinder 9 and is discharged into the interior of the oil storage tank 15 through the drain pipe 14. The separated sludge gradually moves upward through the auger 12 and is discharged into the interior of the sludge storage tank 16 through the sludge discharge pipe 10, thereby realizing the function of extracting while discharging sewage.
