[0034] Here’s how to use it:

[0035] Step 1: When the dry distillation machine is in use, the oily sludge sewage is discharged into the hollow centrifugal cylinder 505 through the top of the treatment box 501 and the feed pipe 506, and then the rotating motor 502 is started to drive the fixed plate 503 to rotate, and the fixed plate 503 drives the support rod 504 and the hollow centrifugal cylinder 505 to rotate, thereby realizing rotation, and then the sewage in the sludge is thrown out, and the sludge is pre-dried;

[0036] Step 2: The sewage flows into the water storage tank 508 and then is discharged through the through hole at the rear side of the water storage tank 508, so that solid-liquid separation can be achieved;

[0037] Step 3: After the pre-drying work is completed, the pushing mechanism 6 is started to squeeze out the solid impurities, so that they fall into the barrel assembly 2, and then pass through the work of the dry distillation machine to achieve the purpose of treatment;

[0038] Step 4: When the dry distillation machine is working, it will generate a large amount of waste gas. When the waste gas passes through the waste gas treatment device 9, it is purified to ensure its quality and then discharged into the air.

[0039] Working process: When in use, the dry distillation machine is powered on, and the sludge is put into the hollow centrifugal cylinder 505 through the treatment box 501 and the feed pipe 506, and then the feed pipe 506 is closed. At this time, the rotating motor 502 is started, and the rotating motor 502 drives the fixed plate 503 to rotate, and the fixed plate 503 drives the support rod 504 to rotate, and the support rod 504 then drives the hollow centrifugal cylinder 505 to rotate. At this time, the sludge can be pre-treated to separate the liquid and solid inside, and the liquid flows into the water storage tank 508. The back side of the water storage tank 508 A drainage hole is provided so that sewage can be discharged for separate treatment. The partition plate 510 is provided to ensure uniform rotation of the sludge to prevent it from piling up and rotating. At this time, solid impurities are accumulated in the hollow centrifugal cylinder 505. At this time, the driving motor 602 is started, and the driving motor 602 drives the threaded shaft 603 to rotate, the threaded shaft 603 drives the threaded sleeve 604 to move, the threaded sleeve 604 drives the driving circular plate 605 to move, and the driving circular plate 605 drives the rotating ring 606, the connecting cylinder 607 and the rotating plate 608 to move, thereby squeezing out the material. It falls into the cylinder assembly 2 of the dry distillation machine, and when the hollow centrifugal cylinder 505 rotates, the partition 510 inside it drives the rotating plate 608 to rotate, which will not affect its centrifugal work. The rotating ring 606 and the connecting cylinder 607 are set to ensure that the rotating plate 608 and the pushing circular plate 605 will not be separated. When the dry distillation machine is drying, most of the moisture in the oil sludge is filtered and processed. At this time, only 1 / 6 of the energy consumption of the traditional dry distillation machine is required to achieve work, which greatly saves energy and greatly improves work efficiency, and the waste gas generated It is discharged into the feed hopper 902 through the exhaust pipe 8, and then discharged through the connecting pipe 903, the connecting pipe 904 and the exhaust nozzle 905. At this time, the exhaust gas contacts the water source, and a part of the harmful substances in the exhaust gas contacts the water source to achieve adsorption and precipitation. Another part of the harmful substances that are insoluble in water are adsorbed by the activated carbon adsorption plate 910 above. The multi-layered activated carbon adsorption plate 910 ensures the quality of exhaust gas treatment so that it can meet the emission standards and avoid its pollution to the air. It has good practical value, and the material is discharged through the discharge pipe 10.

[0040] Embodiment 2:

[0041] In Example 2, the same parts as Example 1 are not repeated again. The difference is that when the water source of the water frame 906 needs to be replaced, the water can be discharged by opening the water outlet plug on the left side to carry out the replacement work, and the Z-shaped connecting pipe 904 is provided to ensure that the air and the water source are in full contact. When replacing the activated carbon adsorption plate 910, the support frame 908 is pulled upward, and then the connecting rod 909 can be driven to move, and then the activated carbon adsorption plate 910 and the spacer ring 911 can be driven to move, and then the activated carbon adsorption plate 910 can be taken out for replacement by rotating the threaded cover 912, and the spacer ring 911 is provided to ensure the separation of the activated carbon adsorption plate 910.
