[0027] The filter assembly includes an arc-shaped support column 7, which is located inside the recovery box 1 and fixedly connected to the recovery box 1. An arc-shaped sealing tube 8 is rotatably connected inside the arc-shaped support column 7. An arc-shaped fixed tube 9 is arranged inside the arc-shaped sealing tube 8. The arc-shaped fixed tube 9 is fixedly connected to the recovery box 1. An arc-shaped filter plate 10 is slidably connected inside the arc-shaped fixed tube 9. An arc-shaped connecting plate 11 is fixed to one end of the arc-shaped filter plate 10. A limiting assembly is arranged on the top of the arc-shaped connecting plate 11.

[0028] The end of the recovery box 1 away from the arc-shaped sealing tube 8 is bolted with a driving motor 4, and the output end of the driving motor 4 is fixed with a circular rotating block 17, which is close to one end of the arc-shaped sealing tube 8 and fixedly connected to the arc-shaped sealing tube 8;

[0029] A circular ring is fixed on the outside of the circular rotating block 17, and a circular groove adapted to the circular ring is opened inside the recycling box 1. The circular rotating block 17 and the recycling box 1 are rotatably connected through the circular ring and the circular groove. The circular rotating block 17 can rotate inside the recycling box 1 through the circular ring and the circular groove. The rotation of the circular rotating block 17 enables the arc-shaped sealing tube 8 to rotate inside the arc-shaped support column 7.

[0030] A rectangular slider is fixed on the top and bottom of the arc filter plate 10, and a rectangular slide groove adapted to the rectangular slider is provided inside the arc fixed tube 9. The arc filter plate 10 and the arc fixed tube 9 are slidably connected through the cooperation of the rectangular slider and the rectangular slide groove, so that the arc filter plate 10 can slide inside the arc fixed tube 9;

[0031] When the printing and dyeing wastewater enters the interior of the recovery box 1, the impurities in the wastewater can be filtered through the arc filter plate 10. When impurities accumulate on the surface of the arc filter plate 10, the operation of the driving motor 4 enables the circular rotating block 17 to rotate. The rotation of the circular rotating block 17 enables the arc sealing tube 8 to rotate inside the arc support column 7, so that the arc sealing tube 8 and the arc support column 7 can form a sealed space. Through the operation of the liquid pump 6, the U-shaped connecting pipe 5 can extract the liquid inside the arc fixed pipe 9;

[0032] In addition, the limiting component includes a rectangular fixed block 12, one end of the top of the arc-shaped connecting plate 11 is fixed with a rectangular fixed block 12, a vertical light rod 13 is slidably connected inside the rectangular fixed block 12, an arc-shaped fixed plate 14 is slidably connected to the outside of the vertical light rod 13 and located at the top of the rectangular fixed block 12, the arc-shaped fixed plate 14 is close to one end of the recycling box 1 and is fixedly connected to the recycling box 1, a circular pull block 15 is fixed to the top of the vertical light rod 13, and a rigid spring 16 is provided between the circular pull block 15 and the arc-shaped fixed plate 14 and located on the outside of the vertical light rod 13;

Through the setting of the arc-shaped slide groove, the arc-shaped connecting plate 11 can slide inside the recycling box 1.

[0034] The circular pull block 15 is pulled in the direction away from the rectangular fixed block 12. The pulling of the circular pull block 15 allows the vertical light rod 13 to slide inside the rectangular fixed block 12, and then the vertical light rod 13 can move out of the rectangular fixed block 12. At this time, the rigid spring 16 is in a stressed and extended state. When the vertical light rod 13 moves out of the rectangular fixed block 12, the arc filter plate 10 can be removed to the inside of the arc fixed tube 9 to facilitate the disassembly and replacement of the arc filter plate 10.

[0035] Working principle: When the heat energy recovery device of the present technical solution is used, after the printing and dyeing wastewater enters the interior of the recovery box 1, the impurities in the wastewater can be filtered through the arc filter plate 10. When impurities accumulate on the surface of the arc filter plate 10, the operation of the driving motor 4 enables the circular rotating block 17 to rotate. The rotation of the circular rotating block 17 enables the arc sealing tube 8 to rotate inside the arc support column 7, so that the arc sealing tube 8 and the arc support column 7 can form a sealed space. Through the operation of the liquid pump 6, the U-shaped connecting tube 5 can extract the liquid inside the arc fixed tube 9;

[0036] The circular pull block 15 is pulled in the direction away from the rectangular fixed block 12. The pulling of the circular pull block 15 allows the vertical light rod 13 to slide inside the rectangular fixed block 12, and then the vertical light rod 13 can move out of the rectangular fixed block 12. At this time, the rigid spring 16 is in a stressed and extended state. When the vertical light rod 13 moves out of the rectangular fixed block 12, the arc filter plate 10 can be removed to the inside of the arc fixed tube 9 to facilitate the disassembly and replacement of the arc filter plate 10.

[0037] All technical features in this embodiment can be freely combined according to actual needs. The above embodiment is a preferred implementation scheme of the utility model. In addition, the utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the utility model.
