[0025] When the glass is recycled and washed, the first washing is performed by the washing device 1. The glass pieces to be recycled are put into the hopper 13, and the glass pieces fall into the vibrating chute 15 from the hopper 13. The vibrating chute 15 vibrates to uniformly disperse the glass pieces, so as to avoid the glass pieces from being accumulated together. Then the glass pieces fall into the vibrating screen 16 from the outlet of the vibrating chute 15. The vibrating screen 16 continuously vibrates, and the glass pieces fall on the conveying belt 12 through the screen holes of the vibrating screen 16. Other larger metal pieces and garbage fall out of the washing device 1 from the outlet of the vibrating screen 16. The glass pieces on the conveying belt 12 are driven to move obliquely upward. The water spraying pipe 14 continuously sprays water to the conveying belt 12 during the moving process. Most of the dirt on the glass pieces is washed away and flows downward with the water. The washed glass pieces reach the highest point of the conveying belt 12 after the first washing, and then fall into the screening and washing device 2.

[0026] The glass pieces fall into the feeding chute 24 from the conveying belt 12, and are guided into the screening and washing barrel 22 through the feeding chute 24. The screening and washing barrel 22 continuously rotates under the driving of the motor 1 23. The glass pieces continuously rotate in the screening and washing barrel 22.

[0027] ​The sewage enters the washing tank 31 through the discharge slot 25, the motor 33 drives the auger 32 to rotate continuously, and the sewage is continuously brought upward under the driving of the auger 32. Since the weight of the glass is greater than that of the water and other impurities, the glass is deposited at the bottom of the washing tank 31 and is continuously brought upward to the top of the washing tank 31. The water and other impurities cannot be deposited at the bottom, and thus automatically flow downward after rising to a certain height, so that the glass and the impurities are separated. After the glass is brought to the top of the washing tank 31, it is recycled into the collection box 27 through the discharge slot 34, and the metal scraps are adsorbed by the electromagnet 35 in the discharge slot 34. After three washing processes, the collected glass in the collection box 27 has reached the recycling standard and can be directly recycled and used.
