The second filter plate 632 can be placed on the first filter plate 6 31 elastically rotates, and a plurality of guide grooves 9 are provided on the first filter plate 631 and the second filter plate 632, and a plurality of filter holes 10 are provided on the guide groove 9. Thus, through this arrangement, when the wastewater enters the filter frame body, it will first be filtered through the plurality of filter holes 10, and most of the filtered impurities will be collected in the guide groove 9 and then smoothly flow down to the bottom, which has the effect of quickly collecting most of the impurities and making it easier to discharge the impurities. Side plates 633 are installed on both sides of the second filter plate 632, and connecting grooves 636 are provided on both sides of the first filter plate 631.

Through this arrangement, when the filter frame as a whole rises, when it encounters the collection frame 65, the bottom of the collection frame 65 will open the two second filter plates 632, so that impurities in the filter frame can be discharged into the collection chamber 66. At this time, the second filter plate 632 is blocked from rising and will rotate, and the hinge spring 635 will be compressed. When the filter frame descends, the hinge spring 635 will rebound and the second filter plate 632 will return to its original position. After returning to its original position, the two second filter plates 632 are in contact, preventing impurities from flowing out.

[0022] The stirring device 5 includes a stirring shaft 51, one of which is fixedly connected to the stirring shaft 51 by a bevel gear assembly 44. A stirring rod 55 is installed on the stirring shaft 51. When the wastewater enters the treatment box 1, the stirring shaft 51 can be driven to rotate by starting the motor 42, so that the stirring rod 55 rotates to achieve a stirring effect, so that the wastewater and the reagent are mixed better. Another bevel gear assembly 44 is provided with a reciprocating screw 46. The driving device 4 also includes a protective shell 45 installed in the treatment box 1. The reciprocating screw 46 is located in the protective shell 45 and rotates. The filter frame is mounted on the bottom thereof, and a threaded seat 49 is threadedly mounted on the reciprocating screw rod 46. A connecting arm 48 is mounted on the filter frame, and the connecting arm 48 is fixedly connected to the threaded seat 49. The bevel gear assembly 44 includes an active bevel gear 442 mounted on the drive shaft 43 and a driven bevel gear 441 meshing with the active bevel gear 442. The stirring shaft 51 and the reciprocating screw rod 46 are fixedly connected to the two driven bevel gears 441 respectively. A guide groove 11 is provided on one side of the protective housing 45, and the threaded seat 49 passes through the guide groove 11. A slot is provided on one side of the protective frame 61 as shown in FIG. Figure 2 and 3 As shown, the slots on the protective frame 61 allow the connecting arm 48 to move, the guide grooves 11 allow the threaded seat 49 to move, and a guide rod 47 passing through the threaded seat 49 is installed in the protective shell 45. The guide rod 47 plays a guiding role and prevents the threaded seat 49 from deflecting when moving on the reciprocating screw 46.

[0023] The working principle of the impurity removal device for oxidation of coking wastewater based on the first embodiment is as follows: when in use, wastewater is input into the filter frame through the infusion pipe 7 and the flow port 12, the wastewater falls downward due to gravity, and the impurities in the wastewater are filtered out by the filter holes 10, and the filtered impurities are deposited in the guide groove 9 and flow down to the bottom of the filter frame, which is located between the two second filter plates 632, and then the motor 42 is started, the motor 42 drives the drive shaft 43 to rotate, and the drive shaft 43 rotates through the two bevel gear assemblies 44 to respectively drive the stirring shaft 51 to rotate and the reciprocating screw 46 to rotate. Specifically, the drive shaft 43 rotates The driving bevel gear 442 is driven to rotate, and the driving bevel gear 442 drives the driven bevel gear 441 to rotate, so that the two driven bevel gears 441 respectively drive the stirring shaft 51 and the reciprocating screw rod 46 to rotate. When the stirring shaft 51 rotates, the stirring rod 55 stirs the wastewater and the treated liquid, thereby performing oxidation treatment, thereby improving the mixing efficiency. When the reciprocating screw rod 46 rotates, the threaded seat 49 reciprocates on the reciprocating screw rod 46, so that the threaded seat 49 drives the connecting arm 48 to move, so that the connecting arm 48 pulls the filter frame to rise or fall. When the filter frame rises, it moves The filter frame 65 moves into the enclosure frame 62. As the filter frame continues to rise, the collection frame 65 will relatively enter between the two filter plate assemblies 63. Finally, as the filter frame rises, the second filter plate 632 contacts the bottom of the collection frame 65, which blocks the movement of the bottom of the second filter plate 632, thereby causing the second filter plate 632 to rotate on the connecting shaft 634. At this time, the hinge spring 635 contracts, so that the two second filter plates 632 will separate, causing the second filter plates 632 to move upward on both sides of the collection frame 65. When the second filter plate 632 moves to the collection port 67, the second filter plate 632 The impurities on the filter will flow into the collection chamber 66 through the collection port 67 and be collected. Meanwhile, the second filter plate 632 continues to rise by leaning against the leaning walls 68 at both ends, so that impurities are continuously discharged into the collection chamber 66 during the rising process. The impurities will flow downstream through the guide groove 9. At this time, when the second filter plate 632 moves to the top of the leaning wall 68, the threaded seat 49 begins to descend, thereby driving the filter frame to descend. When the second filter plate 632 is no longer blocked by the collection frame 65, the two second filter plates 632 will rotate back to their original position, so that the impurities can be filtered and collected at the same time.

The gas pipe 31 is fixed and connected to multiple exhaust pipes 32, and multiple exhaust holes 34 are provided on the exhaust pipe 32. In this way, the oxidation effect of the wastewater can be improved by supplying air from the bottom.
