The utility model has the beneficial effects that: the screen basket structure capable of quickly replacing the screen bars is designed, when partial screen bars of the screen basket are worn, the whole screen basket does not need to be disassembled and replaced, and only the worn screen bars need to be replaced, so that the overall service life of the screen basket is effectively prolonged, resources are saved, and the use cost of equipment is saved; meanwhile, the sieve bars are convenient and quick to replace, the working efficiency is high, the labor intensity is remarkably reduced, the normal production is effectively guaranteed, and the sieve bars are worthy of being popularized and used in a large range.

Description of the drawings:

FIG. 1 is a perspective view of the present invention;

FIG. 2 is a right side view of the present invention;

FIG. 3 is a cross-sectional view taken along A-A of FIG. 2;

FIG. 4 is an enlarged view of the portion B of FIG. 3;

FIG. 5 is an enlarged view of the portion C of FIG. 3;

in the figure, a first ring plate 1, a second ring plate 2, a fastening ring plate 3, an elastic ring plate 4, a sieve bar 5, a reinforcing rib 6, a reinforcing ring 7, a compression spring 8, an insertion through hole 9, an insertion blind hole 10 and a spring groove 11.

The specific implementation mode is as follows:

as shown in fig. 1 to 5, a novel screen basket structure of a coal slime centrifuge comprises a first ring plate 1 and a second ring plate 2 which are concentrically arranged, wherein the first ring plate 1 is fixedly connected with one end of a reinforcing rib 6, the other end of the reinforcing rib 6 is fixedly connected with the second ring plate 2, a plurality of inserting through holes 9 are uniformly distributed on the first ring plate 1 along the circumferential direction, screen bars 5 are slidably inserted in the inserting through holes 9, the novel screen basket structure further comprises an elastic ring plate 4 which is concentrically arranged with the second ring plate 2, the elastic ring plate 4 is positioned between the first ring plate 1 and the second ring plate 2, a plurality of inserting blind holes 10 which are matched with the inserting through holes 9 are arranged on the elastic ring plate 4 along the circumferential direction, the screen bars 5 are inserted in the inserting blind holes 10, a spring groove 11 is arranged on the second ring plate 2, and a compression spring 8 is fixedly connected in the spring groove 11, the other end of the compression spring 8 is fixedly connected with the elastic annular plate 4, a fastening annular plate 3 is concentrically arranged at the outer end of the first annular plate 1, the fastening annular plate 3 is fixedly connected with the first annular plate 1 through a bolt, when the fastening annular plate 3 is attached to the first annular plate 1, two ends of the screen bar 5 are respectively contacted with the fastening annular plate 3 and the hole bottom of the inserting blind hole 10, and the elastic annular plate 4 is attached to the second annular plate 2; a reinforcing ring 7 is arranged on the reinforcing rib 6, the reinforcing ring 7 is concentric with the first ring plate 1, and the reinforcing ring 7 is internally tangent to the screen bars 5; a chamfer is arranged at the orifice of the inserting blind hole 10; all the screen bars 5 are arranged in a conical shape in space; and the surface of the screen bar 5 is coated with a silicon carbide wear-resistant coating.
