The device comprises a screen mesh 1, a support bar 2, a middle support ring 3, a support bar 4, a ribbed plate 5, an inlet support ring 6, an outlet support ring 7, an outlet mounting plate 8, a fixing block 9, an inlet mounting plate 10 and an inlet mounting plate 11.
Detailed Description
The present invention will now be described in more detail with reference to the drawings, in which preferred embodiments of the invention are shown, it being understood that one skilled in the art could modify the invention herein described while still achieving the beneficial effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
As shown in fig. 1-2, a novel coal slurry drum screen structure comprises a cylindrical screen mesh 1, wherein an outlet end of the screen mesh 1 is fixed on an annular outlet mounting plate 8, and the outlet mounting plate 8 is communicated with the screen mesh 1; the outlet mounting plate 8 is provided with a supporting mechanism at the outlet end side close to the screen mesh 1, and the supporting mechanism is sleeved on the screen mesh 1. In this embodiment, the end of the screen 1 where the outlet is provided forms the outlet end of the screen 1, and the end of the screen 1 where the inlet 10 is provided forms the inlet end of the screen 1.
The supporting mechanism comprises a plurality of supporting rings which are sleeved and fixed on the screen mesh 1; the adjacent support rings are connected through a plurality of support bars 2, a plurality of support bars 4 and a plurality of ribbed plates 5; the supporting bars 2 and the supporting bars 4 are distributed in a staggered way; the cross brace 5 is located between the adjacent brace 2 and brace 4.
In this embodiment, the number of support rings is set to 4, including an inlet support ring 6, an outlet support ring 7 and 2 intermediate support rings 3.
In this embodiment, the support mechanism is welded to the outlet mounting plate 8 by a fixing block 9. An annular inlet mounting plate 11 is detachably mounted on a support ring (inlet support ring 6) adjacent to the inlet end of the screen mesh 1; the inlet mounting plate 11 communicates with the screen 1.
In the embodiment, the support rods 4 and the support bars 2 are parallel to the axial lead of the screen mesh 1; the rib 5 is obliquely arranged.
