[0050] Working principle:

[0051] During operation, water, demulsifier, and flocculant are injected into the housing 1 through the auxiliary material inlet 4. The valve 6 on the first connecting pipe 5 is closed. Oily sludge enters the housing 1 through the sludge inlet 3. The motor 2 is started, and the motor 2 rotates. The shaft of the motor 2 drives the connecting shaft 17 to rotate. The rotation of the connecting shaft 17 drives the first stirring rod 18 and the second stirring rod 19 to rotate, which fully stirs and mixes the water, demulsifier, flocculant, and oily sludge in the housing 1. After the demulsifier breaks down the oil-water interface film, it is then aggregated into oily flocs by the flocculant. Afterwards, valve 6 is opened, and the first sludge pump 7 operates to extract the mixture from the casing 1, which has then passed through the first connecting pipe 5 and the hose 9 before being distributed into the aeration tank 10. The first slide 11 is initially placed at the leftmost end of the aeration tank 10. The distribution of material at the second end of the hose 9 can be assisted by a material distributor. During distribution, the material distributor controls the second end of the hose 9 to move from the first end to the second end of the second slide 25 under the action of the second slide 12, distributing the material evenly. After the material distribution in the width direction of the aeration tank 10 is completed, the pull rope is connected to the right side. The pull ring 26 connects to the first slide 11, which can be pulled to the right along the first slide groove 21 to the next fabric placement position. When the first slide 11 is pulled, the roller 31 slides within the first slide groove 21. Then, under the action of the second slide 12, the second end of the fabric distribution machine control hose 9 moves from the second end of the second slide groove 25 to the first end for uniform fabric distribution. By repeating the above operation, the uniform fabric distribution within the aeration tank 10 is completed. After the fabric distribution is completed, a pull rope is connected to the pull ring 26 on the left side to pull the first slide 11 to the next position. On the far left; at this time, the aerator 13 is working and aeration is carried out through the aeration pipe 14. After a certain period of time, flocculent oily substances are generated under the water surface of the aeration pipe 14. At this time, the pull rope is connected to the pull ring 26 on the right side, and then slowly pulled until the first slide 11 reaches the far right. At this time, the flocculent oily substances are gathered together by the first screen 22 and the second screen 33. At this time, the second sludge pump 16 works to extract the flocculent oily substances through multiple second connecting pipes 15, and finally completes the separation of oily substances in the sludge.

[0052] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
