Abstract
The utility model relates to a sieve plate used for grading stones with the advantages of high stone sorting efficiency, material saving and low cost. The sieve plate used for grading stones includes a sieve plate; the surface of the sieve plate is fully provided with round sieve pores and rectangle sieve pores; and the round sieve pores and the rectangle sieve pores are mutually neighboring. The sieve plate used for grading stones has the advantages of effectively improving the sorting efficiency of sieve plate for grading stones, reducing the material consumption and manufacturing cost of sieve plate for grading stones, and prolonging the service life of the sieve plate.
Description
Technical field
The utility model relates to the sieve plate for sorting stone material that a kind of building stones efficiency of separation height, material are economized, cost is low, belongs to metal sieve plate and makes the field.
Background technology
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, because sieve aperture all adopts circular hole to arrange, if the density that arrangement forms between round and round is relative less, though the intensity height of sieve plate, needed material is big, and the efficiency of separation is low, the manufacturing cost height; If it is relatively big to arrange the density that forms between circle and the circle, though the sieve plate consumptive material reduces, the efficiency of separation has improved, manufacturing cost has reduced, but the intensity of sieve plate reduced, and easily breaks, service life is short, this be pendulum in face of people objective reality and an open question always.
Summary of the invention
Purpose of design: avoid the deficiency in the background technology, design the sieve plate for sorting stone material that a kind of intensity height, efficiency of separation height, material are economized, cost is low.
Design: in order to realize above-mentioned purpose of design.The face of sieve plate is covered with round sieve and rectangle sieve aperture and round sieve and the adjacent each other design of rectangle sieve aperture, is major technique feature of the present utility model.The purpose of doing like this is: the one, because being four round sieves, a plurality of round sieves of sieve plate face and a plurality of rectangular mesh screen pore size distribution enclose a rectangle sieve aperture, or four rectangle sieve apertures enclose a round sieve, make sieve plate face institute percent opening improve greatly, joint face between the Kong Yukong reduces, therefore not only improved the efficiency of separation of sieve plate effectively, and greatly reduced material consumption and manufacturing cost building stones; The 2nd, because rectangle sieve aperture 2 is an arc limit rectangle sieve aperture, formed of a plurality of arcs limit rectangle sieve aperture and a plurality of round sieve connecting place are the arc limit for arcwall face, formed limit, and arcwall face and arc limit have good resistance to pressure, resistance to impact and advantages of high strength, therefore it can reduce at the sieve plate consumptive material, efficiency of separation height, under the situation that manufacturing cost reduces, improved the intensity of sieve plate, avoided breaking of sieve plate, use the sieve plate life-span to prolong greatly, solved the unsolved for a long time technical barrier of background technology.
Technical scheme: sieve plate for sorting stone material, it comprises sieve plate, it is adjacent each other with the rectangle sieve aperture that the face of described sieve plate is covered with round sieve and rectangle sieve aperture and round sieve.
The utility model is compared with background technology, and the one, improved the efficiency of separation of stone classification sieve plate effectively; The 2nd, reduced the material consumption and the manufacturing cost of stone classification sieve plate; The 3rd, prolonged service life of sieve plate.
Description of drawings
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 that a plurality of round sieves 2 on 1 on the described sieve plate and a plurality of 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 an arc limit rectangle sieve aperture.The manufacture craft of sieve plate 1 is a prior art, so be not described herein at this.
Embodiment 2: on the basis of embodiment 1, described rectangle sieve aperture 2 is a straight flange rectangle sieve aperture, though the technique effect that straight flange rectangle sieve aperture is produced compares only arc limit rectangle sieve aperture, the technique effect that is produced is better than background technology.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
Claims (5)
