Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1 and 2, the rolling screen for dust-proof sand making comprises a frame 9, a cylindrical screen 1 and a rotating shaft 2 penetrating through the cylindrical screen. The cylindrical sieve is connected with the rotating shaft through a plurality of groups of connecting rod groups 3 which are distributed along the axial direction of the rotating shaft. The rotating shaft is coaxial with the cylindrical screen. The cylindrical screen is disposed obliquely with one end higher and the other end lower. The connecting rods in the same group of connecting rod groups are distributed along the circumferential direction of the rotating shaft, and the adjacent connecting rods 4 in the same group of connecting rod groups are connected together through a second reinforcing plate 5. The second reinforcing plate and the connecting rod are welded together. The connecting rod and the rotating shaft are also connected together through a first reinforcing plate 6. The first reinforcing plate is a right triangle, one right-angle side of the first reinforcing plate is welded with the rotating shaft, and the other right-angle side of the first reinforcing plate is welded with the connecting rod. The high end of the cylindrical screen is provided with a material blocking ring 7 which extends along the circumferential direction of the cylindrical screen and is connected with the cylindrical screen at the radial outer end. The high end of the rotating shaft is connected to the frame through a first bearing 13. The lower end of the shaft is connected to the frame via a second bearing 14. The lower end of the rotating shaft is connected with a motor 15. The motor 15 is used for driving the rotating shaft to rotate. The connecting rod is welded with the rotating shaft.
The outside of the cylindrical screen is provided with a dust-proof housing 17 which is connected with the frame. The end of the dust-proof housing at the high end of the cylindrical screen is provided with a feed inlet 16. A partition plate 27 is provided in the dust-proof housing below the cylindrical screen to prevent coarse sand falling from the lower end of the cylindrical screen from mixing with fine sand falling from the screen holes of the cylindrical screen. A coarse sand outlet 18 and a fine sand outlet 19 are arranged below the dustproof shell. The baffle is obliquely arranged. The partition plate forms a bottom plate of the coarse sand outlet. The opening direction of the fine sand outlet faces downwards, and the opening direction of the coarse sand outlet faces away from the cylindrical screen. An air distribution pipe 20 positioned above the cylindrical screen is arranged in the dustproof shell.
