A valve is installed inside the discharge hopper 19 to facilitate the input and discharge of pulp. A telescopic spring 9 is installed inside the chute 4. One end of the telescopic spring 9 is fixedly connected to the second stirring shaft 5. Through the sliding structure of the second stirring shaft 5 and the first stirring shaft 3, and the deformation of the telescopic spring 9, the second stirring shaft 5 is squeezed and can automatically move downward, shortening the overall height of the first stirring shaft 3 and the second stirring shaft 5. The top of the deinking box 1 is sleeved with a box cover 10, and an electric telescopic rod 11 is installed on the top of the box cover 10. A threaded column 12 is connected to the output end of the electric telescopic rod 11 and is located inside the box cover 10. The outer side of the threaded column 12 is threadedly connected to a filter plate 13, and the inner opening of the filter plate 13 A plurality of filter holes 14 are provided. When the electric telescopic rod 11 drives the threaded column 12 to move downward, the filter plate 13 squeezes the second stirring shaft 5 and the pulp. Through the plurality of filter holes 14, the pulp is easily filtered to separate the liquid and ink therein. The filter plate 13 and the ink absorbing plate 15 are respectively provided with a first threaded hole 16 and a second threaded hole 17 matched with the threaded column 12. The threaded connection structure facilitates the installation and disassembly of the filter plate 13 and the ink absorbing plate 15. The ink absorbing plate 15 is threadedly connected to the outside of the threaded column 12 and located at the top of the filter plate 13. The ink absorbing plate 15 is separated from the scraps in the pulp through the gap with the filter plate 13, contacts with the filtered liquid, and absorbs the ink therein, which is conducive to preventing the waste paper scraps from adhering to its surface. Thereby, the ink absorption efficiency is improved. An air pump 20 is installed on one side of the deinking box 1. The output end of the air pump 20 is fixedly connected to an exhaust pipe 21. One end of the exhaust pipe 21 extends into the deinking tank 2 and is connected to a nozzle 22. Under the action of the air pump 20, the external air can be introduced into the deinking tank 2 through the exhaust pipe 21 and the nozzle 22 to generate a large number of bubbles. When the bubbles move upward, it is convenient to bring the dissolved ink to the top layer solution of the deinking agent. A scraper 23 is connected to one side of the first stirring shaft 3 and located at the bottom of the multiple first stirring blades 6. As the first stirring shaft 3 rotates and moves, the pulp in the deinking tank 2 is repeatedly scraped toward the discharge hopper 19, which is convenient for the discharge of the pulp. An electric heating plate 24 is installed inside the deinking tank 2 and above the scraper 23.A temperature sensor 25 is installed inside the deinking tank 2 and above the electric heating plate 24.

At the same time, the air pump 20 introduces the outside air into the deinking tank 2 through the exhaust pipe 21 and the nozzle 22, generating a large number of bubbles. When the bubbles move upward, they bring the dissolved ink to the top solution of the deinking agent. At this time, the electric telescopic rod 11 drives the threaded column 12 to descend, and the filter plate 13 and the ink absorber 13 on the threaded column 12 are The plate 15 is displaced accordingly, and the filter plate 13 is pressed against the second stirring shaft 5 and squeezed. Through the deformation of the telescopic spring 9 at the bottom of the second stirring shaft 5, the second stirring shaft 5 is moved downward, and the filter plate 13 squeezes the pulp and filters it, so that the liquid and ink in the slurry are separated from the waste paper fragments through multiple filter holes 14. When it reaches a certain position, the surface of the ink-absorbing plate 15 contacts the liquid and absorbs the ink therein. After the end, the electric telescopic rod 11 drives the filter plate 13 and the ink-absorbing plate 15 away from the second stirring shaft 5 and the slurry, and the second stirring shaft 5 is automatically reset under the action of the telescopic spring 9. Since the filter plate 13 and the ink-absorbing plate 15 are both threadedly connected to the threaded column 12, the filter plate 13 and the ink-absorbing plate 15 can be removed by rotating them.
