Description

Technical Field

[0001] The utility model relates to the technical field of material cleaning, in particular to a metal magnetic material cleaning rolling cage screen. Background Art

[0002] Slag from municipal solid waste incineration power plants is primarily a heterogeneous mixture of rocks, sand, glass, ceramics, ash, and a small amount of unburned garbage. After crushing and sorting, the slag exhibits stable chemical properties, good durability, and high strength. Slag is considered a non-toxic general waste and can be directly landfilled or processed for reuse. After technical processing, the slag is suitable for making unburned bricks or other building materials and has considerable recycling value.

[0003] During slag processing, the slag undergoes secondary magnetic separation and secondary crushing. After being crushed by the slag crusher, the slag particles flow out of the crusher along with the flushing water through a trough. A suction-type permanent magnetic separator then undergoes tertiary magnetic separation to remove the fine ferrous magnetic materials within the slag. The selected ferrous magnetic materials then enter an iron washing roller cage sorting screen for water washing. The cleaned ferrous metals can then be dried and sold.

[0004] At present, most of the existing cleaning roller cage screens have small sieve holes on their drum cage screens, so they are easily blocked by materials during the screening and cleaning process, which reduces the screening and cleaning effect. At the same time, since the volume of the screened materials is small and the materials are accumulated in the roller cage screen, the materials at the bottom are easily screened, while the materials on the top of the accumulated materials are not easily screened due to being blocked by the bottom materials, further reducing the screening effect.

The output end of the drive motor is connected to a driving gear. The driving gear is meshed with the driven gear ring 17. The driving motor drives the driving gear to rotate, and the driving gear drives the driven gear ring 17 to rotate, thereby driving the drum cage screen 5 to rotate. The rotation of the drum cage screen 5 also drives the spiral blade 6 therein to rotate.

[0039] The jet pipe 9 is nested in the cavity 2, and the middle part of the upper side of the jet pipe 9 is connected with an air intake pipe 19. The upper end of the air intake pipe 19 passes through the upper side wall of the cavity 2 and extends to the outside of the roller cage screen shell 1. The air intake pipe 19 is connected to the external air source. The air enters the jet pipe 9 through the air intake pipe 19 and is ejected by the jet head 10.

The rotation of the driven gear ring 17 drives the feeding cylinder 13 to rotate, thereby causing the drum cage screen 5 to rotate. The rotation of the drum cage screen 5 simultaneously drives the spiral blade 6 therein to rotate. Under the action of the spiral blade 6, the ferrous metal magnetic material moves toward the right end of the drum cage screen 5. At the same time, clean water enters the water spray pipe 7 through the water inlet pipe 21 and is sprayed by the water spray head 8 to clean the ferrous metal magnetic material in the process of movement. The mixture of materials smaller than 2 mm and water passes through the sub-screening cylinder 12 on the drum cage screen 5. The sieve holes fall to the bottom of the cavity 2 and are then discharged through the discharge port 4. The ferrous metal magnetic materials larger than 2 mm are intercepted and continue to move to the right. During the rotation of the drum cage screen 5, air enters the air jet pipe 9 through the air inlet pipe 19 and is ejected by the air jet head 10. The gas ejected by the air jet head 10 impacts the sieve holes of the sub-screen cylinder 12 and rotates to the top to avoid clogging the sieve holes of the sub-screen cylinder 12, thereby improving the cleaning and screening effect. At the same time, the rotation of the drum cage screen 5 drives the multiple split pieces 11 fixed on the inner wall to rotate. The rotation of the split pieces 11 collides with the ferrous metal magnetic materials, which can disperse the accumulated ferrous metal magnetic materials, thereby facilitating the cleaning and screening of the ferrous metal magnetic materials. The ferrous metal magnetic materials moving to the right end of the drum cage screen 5 fall on the bottom wall of the discharge chute 3 and are discharged along the bottom wall of the discharge chute 3.
