[0022] Example 1

[0023] like Figures 1-4As shown, the device includes a recycling bin 1. A pressure roller A2 is movably connected to one side of the inner cavity of the recycling bin 1 via a bearing. A pressure roller B3 is movably connected to the upper part of the middle of the inner cavity of the recycling bin 1 via a bearing. A pressure roller C4 is movably connected to the other side of the inner cavity of the recycling bin 1 via a bearing. A filter screen 5 is fixedly connected to the inner cavity of the recycling bin 1. The filter screen 5 is inclined. A scraping mechanism 6 is fixedly connected to the upper part of the recycling bin 1. A circulation mechanism 7 is provided on one side of the recycling bin 1. The front and rear sides of one side of the recycling bin 1 are respectively fixedly connected to… There is a connecting frame 8, and a collection wheel 9 is movably connected between opposite sides of each connecting frame 8 via a rotating joint. A drive motor B10 is fixedly connected to the rear side of one of the connecting frames 8. The output shaft of the drive motor B10 is fixedly connected to the collection wheel 9. A groove is opened on one side of the recycling box 1 near the filter screen 5. A pull-out frame 11 is provided on the side of the recycling box 1 near the groove. The pull-out frame 11 is located below the filter screen 5 and is used to collect filtered impurities. A pull plate 12 is slidably connected to the inner cavity of the pull-out frame 11.

[0024] The scraping mechanism 6 includes a support frame 61, with a drive cylinder 62 fixedly connected to the upper part of the support frame 61. The output shaft of the drive cylinder 62 passes through the support frame 61, and a pressure plate 63 is fixedly connected to the output shaft of the drive cylinder 62. Scraper heads 64 are fixedly connected to both sides of the lower part of the pressure plate 63. The dyed and finished fabric enters the recycling box 1 and passes through pressure rollers A2, B3, and C4 in sequence. One end of the fabric is wound around the collection wheel 9, which drives the drive motor B10. The drive motor B10 drives the collection wheel 9 to rotate, and the fabric passing through pressure rollers A2, B3, and C4 is squeezed, causing the fabric to... The residual dye liquor is fully squeezed out, and the squeezed-out dye liquor drips onto the inclined filter screen 5. The filter screen 5 can intercept solid particles such as fibers and impurities, thus initially purifying the dye liquor. The filtered dye liquor flows into the bottom of the recovery box 1 along the inclined filter screen 5, while the filtered impurities are trapped on the filter screen 5 and can be cleaned periodically by the pull-out frame 11. The output shaft of the drive cylinder 62 drives the pressure plate 63 and the scraper head 64 to move up and down, scraping the liquid off the moving fabric. By using the above structure in combination, the efficiency of dye liquor recovery is improved. The pull-out frame 11 can be pulled out along the groove to facilitate cleaning the impurities trapped by the filter screen 5 and maintain filtration efficiency.

[0025] Example 2

[0026] like Figures 5-6 As shown, the circulation mechanism 7 includes an L-shaped pipe 71, which is connected to one side of the recycling box 1. A water pump 72 is connected to the rear side of the L-shaped pipe 71. A conveying pipe 73 is connected to the upper part of the water pump 72. A mixing tank 74 is provided at the lower part of the conveying pipe 73.

[0027] A drive motor A75 is fixedly connected to the upper part of the mixing tank 74. The output shaft of the drive motor A75 passes through the mixing tank 74. A stirring rod 76 is fixedly connected to the output shaft of the drive motor A75 through a coupling. Mixing blades 77 are fixedly connected to the surface of the stirring rod 76.

[0028] The rear side of the mixing tank 74 is connected to an output pipe 710. A solenoid valve 711 is fixedly connected to the surface of the output pipe 710. Dye liquor falling into the bottom of the recovery tank 1 is pumped by a water pump 72, which drives an L-shaped pipe 71 to extract the dye liquor from inside the recovery tank 1 and transport it to a conveying pipe 73. The conveying pipe 73 then transports the dye liquor into the mixing tank 74. Workers add an appropriate amount of raw materials into the mixing tank 74 through a vertical pipe installed on the mixing tank, and drive a drive motor B10. The output shaft of the drive motor B10 drives a coupling to drive the agitator. When the stirring rod 76 rotates, it drives the fixedly connected mixing blade 77 to rotate. The mixing blade 77 stirs the raw materials and the recycled dye liquor, so that the dye liquor can be recycled and reused. The stirring of the dye liquor makes its composition uniform. When the stirring rod 76 rotates, it can simultaneously drive the connecting rod 78 set on the surface to rotate, and the connecting rod 78 drives the cleaning plate 79 to rotate to scrape off the dye liquor adhering to the inner wall of the mixing tank, preventing the dye liquor from depositing and scaling. The uniformly mixed dye liquor can be discharged through the output pipe 710. The solenoid valve 711 controls the discharge volume, so that the dye liquor can be directly reused in the dyeing and finishing process, realizing recycling.
