Detailed Description
Referring to fig. 1 to 7, the present utility model provides an arc-shaped sieve sheet for ore screening, which comprises: the novel sieve plate comprises a first arc sieve plate 1 and a second arc sieve plate 2, wherein a gap 3 is formed between the bottom of the first arc sieve plate 1 and the bottom of the second arc sieve plate 2, a plurality of guide rollers are arranged in the gap 3 and distributed along an inclined straight line, and a second filter hole is formed between two adjacent guide rollers.
The first arc-shaped screen piece 1, the second arc-shaped screen piece 2 are two little arc-shaped pieces, and the strong of the ability steelframe of its resistance to deformation, when granule falls into first arc-shaped screen piece 1, the 2 surface of second arc-shaped screen piece, and the granule whereabouts, and big granule slides down along the arc inboard, slides gap 3 department, then falls into on a plurality of deflector roll, then along deflector roll, the inclined structure whereabouts that gap 3 formed to the tip of screen piece.
The ore which directly falls into the gap opening 3 from the upper part is filtered by the second filtering holes, and still has good screening effect.
The device basically does not need to clean large ore particles accumulated at the lowest center of the arc-shaped sieve sheet in the use process, and the problem of blockage is not worried.
The deflector roll includes fixed column 4, and the one end and the first arc sieve piece 1 fixed connection of fixed column 4, the other end and the second arc sieve piece 2 fixed connection of fixed column 4, the outside cover of fixed column 4 is equipped with movable section of thick bamboo 5.
