[0018] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 As shown, a stirring device for oil sludge treatment includes a stirring drum 1, in which a stirring assembly 2 for stirring the oil sludge in the stirring drum 1 is arranged, the stirring assembly 2 is fixedly arranged on the stirring drum 1, and a filter screen 3 for separating particulate debris is also coaxially slidably arranged in the stirring drum 1.

[0020] A connecting block 4 is fixedly arranged on the mixing drum 1, and a spring 5 is fixedly connected to the connecting block 4. Four springs 5 ​​are arranged, and the spring 5 is used to support the filter screen 3. One end of the spring 5 away from the connecting block 4 is fixedly connected to the filter screen 3. The stirring assembly 2 comprises a motor 6, a stirring shaft 7 and a stirring rod 8 annularly fixedly arranged on the stirring shaft 7. The stirring rod 8 is arranged in the mixing drum 1. A support rod 9 is also fixedly arranged on the stirring shaft 7. A flattening rod 10 is coaxially arranged on the support rod 9, and the flattening rod 10 abuts against the filter screen 3. The motor 6 is fixedly arranged on the mixing drum 1, and the stirring shaft 7 is coaxially fixedly arranged on the output shaft of the motor 6. A plurality of protrusions 11 are annularly fixedly arranged on the flattening rod 10, and the protrusions 11 abut against the filter screen 3, and the flattening rod 10 is arranged on a side of the filter screen 3 close to the motor. The protrusions 11 assist in flattening the sludge. When the flattening rod 10 rotates around the stirring shaft 7, the flattening rod 10 also rotates around the support rod 9, so that the flattening effect is better.

[0021] A striking assembly 12 is symmetrically fixedly arranged on the mixing drum 1. The output end of the striking assembly 12 is rotatably connected to a striking rod 13 for driving the filter 3 to slide. The striking rod 13 abuts against the filter 3. A counterweight block is arranged at one end of the striking rod 13 close to the filter 3.

[0022] The striking assembly 12 includes a fixed plate 14, a support rod 15, a second motor 16 and a swing rod 17. The fixed plate 14 is fixedly arranged on the mixing drum 1, the support rod 15 is fixedly arranged on the fixed plate 14, the striking rod 13 is rotatably connected to one end of the support rod 15 away from the fixed plate 14, the second motor 16 is fixedly arranged on the fixed plate 14, and the second motor 16 is arranged between the support rod 15 and the mixing drum 1, the swing rod 17 is fixedly arranged on the output shaft of the second motor 16, and one end of the swing rod 17 away from the motor abuts against the striking rod 13. When the swing rod 17 swings downward, the counterweight block fixedly connected to the striking rod 13 also drives the striking rod 13 to rotate downward, and the striking rod 13 then drives the abutted filter 3 to slide downward. When the motor controls the swing rod 17 to slide and rise, the striking rod 13 abutted by the swing rod 17 rotates and rises, and then the spring 5 drives the filter 3 to rise, so that the filter 3 slides back and forth up and down.

The scraper rods 19 abut against the inner wall of the stirring drum 1. When the stirring shaft 7 drives the stirring rods 8 to rotate to promote the mixing of the oil sludge, the stirring shaft 7 also drives the cross bars 18 to rotate in the stirring drum 1. The scraper rods 19 fixedly connected to the cross bars 18 rotate closely against the inner wall of the stirring drum 1 to scrape off the oil sludge adhered to the inner wall of the stirring drum 1 to avoid uneven mixing of the oil sludge.

[0024] When the utility model is in use, when the oil sludge is put into the mixing drum 1 for stirring, the oil sludge will first pass through the filter screen 3, and the filter screen 3 will filter out the particles in the oil sludge and leave them on the filter screen 3. The filtered oil sludge will leak into the mixing drum 1. When the oil sludge is put in, the motor 1 6 is started, and the motor 1 6 controls the flattening rod 10 to rotate, and the oil sludge on the filter screen 3 is rotated and flattened to avoid the oil sludge from accumulating in one place, so that the oil sludge is evenly distributed on the filter screen 3, and the filtering process is accelerated. After the filtering is completed, a part of the solid particles are stuck in the filter holes, and the motor 2 16 is started, and the motor 2 16 controls the swing rod 17 to rotate. Then, the end of the downward pressure rod close to the filter screen 3 abutted by the swing rod 17 is pressed down due to gravity, driving the filter screen 3 to slide back and forth in a small range in the mixing drum 1, so that the particles stuck in the filter holes are separated from the filter holes and come onto the filter screen 3, which is convenient for subsequent centralized cleaning.
