[0026] Working principle: when in use, the two input ends of the two-way solenoid valve 7 are connected to the coking wastewater drainage pipe and the flocculant delivery pipe respectively. The wastewater and flocculant are mixed through the two-way solenoid valve 7 and then enter the spiral mixing tube 8. The mixed wastewater enters the mixing treatment box 10. The flotation machine connecting pipe 41 is connected to the flotation machine. The bubbles generated by the flotation machine enter the mixing treatment box 10 through the flotation machine connecting pipe 41. Under the action of the bubbles, the tar and condensate in the wastewater will float upward to the surface of the wastewater. When a certain amount of wastewater enters the mixing treatment box 10, the lifting plate 24 will be pressed to move downward, causing the support spring 25 to be compressed. At this time, the tar and condensate on the surface of the wastewater will be discharged through the drainage opening 26. The wastewater after preliminary treatment will enter the drainage pipe 12 and finally be sprayed out from the nozzle 13. Turn on the first motor 6 to drive the disc 4 to rotate slowly. The circular filter plate 34 inside the disc 4 blocks the condensate. The tar and the treated wastewater pass through the circular filter plate 34 and enter the connecting chamber 2. The water source sprayed by the nozzle 13 can flush the condensate on the surface of the circular filter plate 34, so that the tar on the surface of the condensate is flushed into the connecting chamber 2. During the rotation of the disc 4, the slide rod 38 moves along the slide groove 35. When the slide rod 38 moves to the end of the slide groove 35, the gear 33 is meshed with the arc-shaped tooth plate 32. As the disc 4 rotates, the gear 33 is engaged with the arc-shaped tooth plate 32. 3 will move along the surface of the arc-shaped tooth plate 32. At this time, the gear 33 will rotate and drive the circular filter plate 34 to flip over, so that the condensate on the surface of the circular filter plate 34 falls into the storage chamber 3. The fan 39 transports air to the air pipe 27. The air pipe 27 sprays air to the surface of the circular filter plate 34 to clean the flipped circular filter plate 34 and prevent condensate from being blocked in the circular filter plate 34. When the gear 33 is separated from the surface of the arc-shaped tooth plate 32, the slide bar 38 will move into the slide groove 35 again, so that the flipped circular filter plate 34 will not shake when moving. The tar wastewater entering the connecting chamber 2 will fall onto the surface of several collecting plates 28. The tar is collected by several collecting plates 28 arranged above and below, so that the tar adheres to the surface of the collecting plates 28. The wastewater with tar removed will flow through the surface of the collecting plates 28 and be discharged from the connecting pipe 22. When the collecting plates 28 located in the connecting chamber 2 have collected for a period of time, the transmission motor 21 will start to rotate and drive the connecting block 20 to rotate. Through the setting of the connecting chamber 16, the several collecting plates 28 on the right side are rotated into the cooling and molding chamber 18. When the rotation is completed, the transmission motor 21 will be in a self-locking state. At this time, the second motor 44 will start to control the rotating rod 37 to flip, so that the upper end of the collecting plate 28 flips to the lower end, and at the same time the telescopic cylinder 29 and the vibrator 43 will start, the telescopic cylinder 29 starts to drive the pull plate 30 to move outward, and the movement of the pull plate 30 makes the several folded collecting plates 28 flattened. After the vibrator 43 is started, it drives the slider 40 to shake up and down, and the collecting plates 28 in the several cooling molding cavities 18 will shake synchronously. Under the action of the fan 14, the cool air generated by the refrigeration plate 19 will be cooled in the cooling molding cavity 18. The tar adhering to the surface of the collecting plate 28 is cooled and agglomerated by the circulating flow. The agglomerated tar is separated from the bottom of the cooling molding cavity 18 by the shaking of the collecting plate 28, completing the separation and collection of the tar. When the separation is completed, the rotating rod 37 will rotate again, so that the collecting surface of the collecting plate 28 is rotated to the upper side again. At the same time, the telescopic cylinder 29 will drive the pulling plate 30 to retract, so that several collecting plates 28 are folded. The transmission motor 21 can make the several collecting plates 28 on the left side be turned into the connecting cavity 2 again for tar collection.
