Abstract
The invention relates to a sieve plate for stone classification with high stone classification efficiency, material conservation and low cost. The sieve plate comprises the sieve plate, wherein round sieve pores and rectangular sieve pores are distributed on the surface of the sieve plate, and are adjacent to each other. The sieve plate has the advantages that: 1, the classification efficiency of the stone classification sieve plate is effectively improved; 2, material consumption and manufacture cost of the stone classification sieve plate are reduced; and 3, the service life of the sieve plate is prolonged.
Description
Technical field
The present invention relates to the sieve plate for sorting stone material that a kind of building stones efficiency of separation is high, material is economized, cost is low, belong to metal sieve plate and manufacture field.
Background technology
The all CN201049342Y of the applicant, title " sieve plate for sorting stone material ", it comprises the substrate of some sieve apertures, the rectangular sieve aperture of sieve aperture.Its objective reality is: the one, and because all adopting circular hole, arranges sieve aperture, and if the density that between circle and circle, arrangement forms is relatively little, although the intensity of sieve plate is high, needed material is large, and the efficiency of separation is low, and manufacturing cost is high; If it is relatively large to arrange the density forming between circle and circle, although sieve plate consumptive material reduces, the efficiency of separation has improved, manufacturing cost has reduced, but the strength decreased of sieve plate, easily break, service life is short, and this is the objective reality of pendulum in face of the people and an open question always.
Summary of the invention
Purpose of design: avoid the deficiency in background technology, design the sieve plate for sorting stone material that a kind of intensity is high, the efficiency of separation is high, material is economized, cost is low.
Design: in order to realize above-mentioned purpose of design.The face of sieve plate is covered with the adjacent design each other of round sieve and rectangle sieve aperture and round sieve and rectangle sieve aperture, is technical characteristics of the present invention.The object of doing is like this: the one, and because being four round sieves, multiple round sieves of sieve plate face and multiple rectangular mesh screen pore size distribution enclose a rectangle sieve aperture, or four rectangle sieve apertures enclose a round sieve, sieve plate face institute percent opening is improved greatly, joint face between Kong Yukong reduces, therefore not only effectively improve the efficiency of separation of sieve plate to building stones, and greatly reduced material consumption and manufacturing cost; The 2nd, because rectangle sieve aperture is arc-shaped side rectangle sieve aperture, multiple arc-shaped side rectangle sieve apertures be connected with multiple round sieves face that place forms for arcwall face, the limit that forms be arc-shaped side, and arcwall face and arc-shaped side have the advantages that good resistance to pressure, resistance to impact and intensity are high, therefore it can reduce at sieve plate consumptive material, the efficiency of separation is high, in the situation that manufacturing cost reduces, improve the intensity of sieve plate, avoid breaking of sieve plate, use the sieve plate life-span greatly to extend, solved background technology unsolved technical barrier for a long time.
Technical scheme: sieve plate for sorting stone material, it comprises sieve plate, it is adjacent each other with rectangle sieve aperture that the face of described sieve plate is covered with round sieve and rectangle sieve aperture and round sieve.
The present invention compared with background technology, the one, effectively improved the efficiency of separation of stone classification sieve plate; The 2nd, reduce material consumption and the manufacturing cost of stone classification sieve plate; The 3rd, extend service life of sieve plate.
Accompanying drawing explanation
Fig. 1 is the structural representation of sieve plate for sorting stone material.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Sieve plate for sorting stone material, it comprises sieve plate 1, described sieve plate 1 is potassium steel sieve plate or medium managese steel sieve plate or ultra-high manganese steel sieve plate.It is adjacent each other with rectangle sieve aperture 3 that the face of described sieve plate 1 is covered with round sieve 2 and rectangle sieve aperture 3 and round sieve 2.That is to say, the multiple round sieves 2 on 1, described sieve plate and multiple rectangle sieve apertures 3 distribute and are four round sieves 2 and enclose a rectangle sieve aperture 3, or four rectangle sieve apertures 3 enclose a round sieve 2.Described rectangle sieve aperture 2 is arc-shaped side rectangle sieve aperture.The manufacture craft of sieve plate 1 is prior art, therefore be not described herein at this.
Embodiment 2: on the basis of embodiment 1, described rectangle sieve aperture 2 is straight flange rectangle sieve aperture, although only arc-shaped side rectangle sieve aperture of the technique effect that straight flange rectangle sieve aperture produces ratio, the technique effect producing is better than background technology.
It is to be understood that: although above-described embodiment is to the mentality of designing of the present invention detailed text description of contrasting; but these text descriptions; just the simple text of mentality of designing of the present invention is described; rather than restriction to mentality of designing of the present invention; any combination, increase or modification that does not exceed mentality of designing of the present invention, all falls within the scope of protection of the present invention.
Claims (1)
