Abstract
The utility model relates to sieving equipment for materials, in particular to anti-blocking type sieving slices of a sieving machine. The outline of each anti-blocking type sieving slice is formed in a manner that a rotating profile line rotates around a rotating shaft by one circle, wherein the rotating profile line is formed by a trapezoid and a square. A rotating shaft is an axial central line of a sieving shaft where the anti-blocking type sieving slice is located. The butterfly-shaped anti-blocking type sieving slices can form trapezoid spaces in axial sections between two adjacent sieving slices in the same group of sieving shafts. The materials can not be bonded on the sieving slices, and sieving holes are prevented form being blocked by the materials.
Description
Technical field
The utility model relates to the screening plant of material, and specifically a kind of block-resistant type of screening machine sieve sheet can be used for the classification processing of coal-fired boiler fuel.
Background technology
At present, roller picker is mostly adopted in the screening of every profession and trade coal-fired boiler fuel.As shown in Figure 1 and Figure 2, the compass screen surface of roller picker is made up of the sieve axle group of sieve sheet 3 many groups string, a roller picker generally is made up of 9～15 groups of sieve axles, and sieve axle group is fixed on the body of roller picker extension set by bearing, bearing block, drives rotation by motor reducer.Gap between the last adjacent two sieve sheets of the same sieve axle of this roller picker is rectangle, during the screening machine operation, sieved through sieve axle group by sieve material 1 on the compass screen surface, be very easy to form bonding in the rectangle sieve aperture between adjacent two sieve sheets, long-pending full with substance 2 in the rectangle sieve aperture, sieve aperture is blocked, the effective area of screening machine compass screen surface is diminished, thereby cause the screening efficiency of screening machine to reduce.
The utility model content
In order to solve that material blocks sieve aperture and the problem that reduces screening efficiency, the purpose of this utility model is to provide a kind of block-resistant type sieve sheet of screening machine.
The purpose of this utility model is achieved through the following technical solutions:
The profile of the utility model block-resistant type sieve sheet is rotated a circle around rotating shaft by the rotation profile and forms, and described rotation profile is by trapezoidal and square the composition; Described rotating shaft is the longitudinal center line of block-resistant type sieve sheet place sieve axle.
Wherein: described trapezoidal be isosceles trapezoid, the trapezoidal and described square centerline collineation of these isosceles; Space between the adjacent two block-resistant types sieve of the described sieve axle axial cross section sheet is trapezoid space; Described trapezoid space is the isosceles trapezoid space;
Described block-resistant type sieve sheet is solid construction, and the centre has sieve sheet axis hole; The block-resistant type sieve sheet of described solid construction is overall structure or radially is divided into the identical two parts of shape and structure;
Described block-resistant type sieve sheet is hollow-core construction, and the centre has sieve sheet axis hole; The block-resistant type sieve sheet of described hollow-core construction is overall structure or radially is divided into the identical two parts of shape and structure;
The circumferential surface of described block-resistant type sieve sheet is that smooth cambered surface or the circumferential surface of described block-resistant type sieve sheet are evenly equipped with a plurality of sieve sheet teeth.
Advantage of the present utility model and good effect are:
New shape block-resistant type sieve sheet of the present utility model axially can form trapezoid space in the section between the same group of adjacent two sieve sheets of sieve axle group, material can not be bonded on the sieve sheet, has avoided sieve aperture to be stopped up by material.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.As shown in Figure 5, the profile of the utility model block-resistant type sieve sheet 5 is rotated a circle around rotating shaft 8 by rotation profile 7 and forms, rotation profile 7 is by isosceles trapezoid and square the composition, trapezoidal and the described square centerline collineation of these isosceles, rotating shaft 8 are the longitudinal center line of block-resistant type sieve sheet 5 places sieve axle.
The sieve axle is gone up a plurality of choke-preventing screen sheets 5 is installed, and the space between the adjacent two block-resistant types sieve of the sieve axle axial cross section sheet 5 is trapezoid space 6, and this trapezoid space 6 is the isosceles trapezoid space, and axially outer direction is uncovered by sieve.
Block-resistant type sieve sheet 5 of the present utility model is solid construction or hollow-core construction, and the centre has sieve sheet axis hole 9.
Embodiment one
Shown in Fig. 6 A, Fig. 6 B, the block-resistant type of present embodiment sieve sheet 5 is overall structure, and the circumferential surface of block-resistant type sieve sheet 5 is evenly equipped with a plurality of sieve sheet teeth 10.
Embodiment two
Shown in Fig. 7 A, Fig. 7 B, the block-resistant type of present embodiment sieve sheet 5 is overall structure, and the circumferential surface of block-resistant type sieve sheet 5 is smooth cambered surface.
Embodiment three
Shown in Fig. 8 A, Fig. 8 B, the block-resistant type of present embodiment sieve sheet 5 radially is divided into the identical two parts of shape and structure, and the circumferential surface of block-resistant type sieve sheet 5 is evenly equipped with a plurality of sieve sheet teeth 10.
The block-resistant type compass screen surface is sieved material 4 and is dropped on the compass screen surface, and material easily falls in the trapezoid space 6, drives the lower edge direction initialization in rotary screen axle group and moves, and leaks down less than the material of sieve aperture, continues mobile up to eliminating greater than the material of sieve aperture.Because the translational speed of material is synchronously impossible with the linear velocity of sieve sheet, so there is relative motion between the two, can produce friction in mobile process, so material can not be bonded on the sieve sheet, sieve aperture just can not stop up yet.
Block-resistant type sieve sheet of the present utility model is steel-casting, and sieve sheet casting back reply profile endoporus carries out machining, and sieve sheet exposed face does not carry out machining.Be loaded in the screening machine after the sieve sheet machines and use.
