[0032] Figure 5It is a cross-sectional view of a device for purifying and discharging waste liquid after recycling paper towel scraps;

[0033] like Figure 1-5 As shown, a device for purifying and discharging waste liquid after recycling paper towel scraps disclosed in the present invention may include: a purification mechanism, a squeezing mechanism, an upper plate mechanism and other components;

[0034] like Figure 1-4 As shown, the purification mechanism includes a filter box 1, a motor 2, a shaft 3, a scraper 4, a mounting plate 5, a brush 6, a filter screen 7, a feed pipe 8, an outlet slot 9, and a collection box 10;

[0035] The motor 2 is installed at the center of the front surface of the filter box 1, the shaft 3 is rotatably installed on the inner wall of the filter box 1 and one end is fixedly connected to the driving end of the motor 2, two scrapers 4 are correspondingly installed on the side of the shaft 3, two mounting plates 5 are installed on the side of the scraper 4 and are on one side of the scraper 4, each brush 6 is installed on the side of the corresponding mounting plate 5, each scraper 4 and the side of the mounting plate 5 are provided with a through hole, the lower surface of the filter box 1 is provided with an opening, the filter screen 7 is arranged in the opening, the feed pipe 8 is installed on the side of the filter box 1, the outlet slot 9 is provided on the other side of the filter box 1, and the collection box 10 is provided on the other side of the filter box 1 and close to the outlet slot 9;

[0036] When in use, the waste liquid recovered from the paper towel scraps is fed into the filter box 1 through the feed pipe 8. Due to gravity, the waste liquid gathers at the bottom of the filter box 1 and is filtered by the filter screen 7. Water flows out through the filter screen 7, and the paper towel scraps are left in the filter box 1. The running motor 2 drives the shaft rod 3 to rotate, and the rotating shaft rod 3 drives the scraper 4, the mounting plate 5 and the brush 6 to rotate. The rotating scraper 4 can scrape the remaining paper towel scraps solids into the collection box 10 through the outlet slot 9. At the same time, the upper surface of the filter screen 7 is cleaned by the rotating brush 6 to avoid clogging of the filter screen 7, remove the impurities of the paper towel scraps in the wastewater, and realize the purification and discharge of the waste liquid of the paper towel scraps;

[0037] like Figure 1-5 As shown, the extrusion mechanism includes a side plate 21, an electric push rod 22, a pressing plate 23, a fixing plate 24, an output pipe 25, and a filter plate 26;

[0038] The side plate 21 is installed on the other side of the filter box 1 and is above the outlet slot 9. Two fixing plates 24 are correspondingly installed on the lower surface of the side plate 21 and the lower ends are fixedly connected to the collection box 10. Two electric push rods 22 are installed on the lower surface of the side plate 21. The pressing plate 23 is installed on the lower ends of the two electric push rods 22 and is adapted to the collection box 10. A plurality of output pipes 25 are evenly installed on the lower surface of the collection box 10, and each filter plate 26 is arranged at the upper end of the corresponding output pipe 25.

[0039] When the collection box 10 is full of paper towel scraps, the electric push rod 22 extends and drives the pressing plate 23 to descend. The descending pressing plate 23 enters the collection box 10 and cooperates with the collection box 10 to squeeze the paper towel scraps therein, squeezes out the water absorbed inside, and discharges it through the output pipe 25. At the same time, the filter plate 26 can prevent the paper towel scraps from being discharged from the output pipe 25 during the squeezing process. The squeezing is performed until no water is discharged from the output pipe 25. Then, the electric push rod 22 shortens and drives the pressing plate 23 to rise and move out of the collection box 10. The paper towel scraps are taken out of the collection box 10 for reuse, and the water absorbed by the paper towel scraps is extracted, thereby avoiding waste.

[0040] like Figure 1-5 As shown, the upper plate mechanism includes a strip plate 11, an upper plate 12, a slot 13, a limit plate 14, a spring 15, a clamp 16, a center slot 17, a winding rod 18, a stretcher 19, and a knob 20;

[0041] Two strip plates 11 are installed on the upper surface of the filter box 1, the upper plate 12 is hinged between the two strip plates 11, each slot 13 is opened on the side of the corresponding strip plate 11, and a cavity is opened on one side of each slot 13 inside the upper plate 12, each limit plate 14 is arranged in the corresponding cavity, each spring 15 is arranged in the corresponding cavity and is located on one side of the limit plate 14, each clamp 16 is installed at the center of the side of the corresponding limit plate 14 and extends to the aligned slot 13, the center slot 17 is opened in the upper plate 12 and is located between the two upper plates 12, the winding rod 18 is rotatably installed in the center slot 17, each stretching 19 is installed at the center of the other side of the corresponding limit plate 14 and the end extends to the center slot 17 and is fixedly connected to the winding rod 18, and the knob 20 is installed at the end of the winding rod 18 extending to the outside of the upper plate 12;

[0042] When it is necessary to inspect the internal components of the filter box 1 or clean its inner wall, the rotating knob 20 drives the winding rod 18 to rotate and wind the two stretching rods 19, and pulls the two limit plates 14 to move. Each moving limit plate 14 compresses the spring 15 and drives the card 16 to move out of the card slot 13 and into the card slot 13, so that the fixation of the upper plate 12 can be released, and then the upper plate 12 can be rotated around the hinge to open the filter box 1, and then the internal components can be inspected or the inside of the filter box 1 can be cleaned. When closing, the rotating knob 20 allows the two card members 16 to enter the card slot 13 through the above operation, and then the upper plate 12 is reversed around the hinge to cover the filter box 1. At this time, the two card members 16 are aligned with the two card slots 13, and then the knob 20 is released to allow the two springs 15 to rebound and drive the two card members 16 to be inserted into the two card slots 13, fix the upper plate 12, and the closing is completed.
