[0002] The incinerator uses coal for incineration. After incineration, slag will be generated in the incinerator. Metal materials will be doped in the slag. The slag is conveyed out by a belt, and the slag is subjected to magnetic separation by a magnetic separator to separate the metal from the slag. After the slag is selected for iron, a vibrating screen is used to remove the water in the slag, so as to realize the recycling of the slag.

[0003] In the existing process of removing water from the slag after iron selection, a vibrating screen is used to throw out the water in the slag. After the water is thrown out, it will pollute the on-site environment, causing a large amount of water accumulation on the on-site ground, and subsequent cleaning of the on-site environment is required, resulting in an increase in labor costs and time costs in the later stage.

[0004] Therefore, the technical personnel in this field provide a water removal and collection device for the slag after iron selection in an incinerator to solve the problems raised in the above background technique. Content of the Utility Model

[0023] Specifically, the slag is fed into the inside of the drum screen 7 through the belt conveyor feeding port 4. After the water in the drum screen 7 is thrown out, and through the vibration of the vibrating motor 18, the water enters the water flinging tank 2, and the water enters the collection bucket 6 through the through hole 17 and the water hole plate 5.

[0024] Friction ring members 8 are fixedly arranged on the outer walls at both ends of the drum sieve 7. A linkage shaft 9 is installed outside the drum sieve 7. Friction wheels 10 are installed at both ends of the linkage shaft 9. The friction wheels 10 are in mutual contact with the friction ring members 8. The right end of the linkage shaft 9 is fixedly connected to a rotating shaft rod 11. And a first reversing gearbox 12 is installed at one end of the rotating shaft rod 11 away from the linkage shaft 9. A transmission shaft 13 is connected to one side of the first reversing gearbox 12. A second reversing gearbox 14 is installed at one end of the transmission shaft 13 away from the first reversing gearbox 12. A driving motor 15 is connected to one side of the second reversing gearbox 14. The driving motor 15 is mutually connected with the transmission shaft 13 through the second reversing gearbox 14.
