Referring to FIGS. 2 and 3, the screen plate structure may include a first screen plate 100, a second screen plate 200, and a screen support plate 300.

For convenience of explanation, directions perpendicular to the upper surface of the first screen plate 100 and perpendicular to each other are defined as a first direction and a second direction, and a direction perpendicular to the upper surface of the first screen plate 100 is defined as a third direction . Here, the first direction, the second direction, and the third direction may mean the opposite direction of the first direction, the opposite direction of the second direction, and the opposite direction of the third direction.

The first screen plate 100 and the second screen plate 200 are overlapped with each other so that the first screen plate 100 is assembled to be supported by the second screen plate 200. At this time, the first screen plate 100 and the second screen plate 200 can change their positions along the first direction, but can not change their positions along the second direction. That is, the first screen plate 100 may move along the first direction with respect to the second screen plate 200.

The first screen plate 100 includes a plurality of first apertures 110, first securing apertures 120, protrusions 130, a first adjusting bolt 140 and a second adjusting bolt 142 .

A plurality of first openings (110) are arranged along the first direction and the second direction at a central portion of the first screen plate (100). The first openings 110 may have various sizes and shapes depending on the particles to be sorted. For example, as shown in FIG. 2, the first openings 110 may each have a square shape with sides parallel to each other along the first and second directions.

The first fixing openings 120 may be disposed at both side edges of the first screen plate 100. For example, as shown in FIG. 2, a plurality of first securing openings 120 may be spaced apart from one another in the first direction, and first openings 120 (110) may be disposed.

The first fixing openings 120 have an elliptical shape extending along the first direction. That is, the first fixing openings 120 may be semicircular at the ends along the first direction, and the portions between them may be straight lines parallel to each other.

The protrusion 130 protrudes from the lower surface of the first screen plate 100 along a third direction perpendicular to the upper surface of the first screen plate 100. Meanwhile, the protrusion 130 does not overlap with the first openings 110 or the first fixing openings 120 when viewed in the third direction, and may extend along the first direction. The protrusion 130 may have a first width W1 along the second direction. In the exemplary embodiments, a pair of protrusions 130 may be disposed on the bottom surface of the first screen plate 100, and they may be spaced from each other along the second direction.

Referring again to FIG. 2, the second screen plate 200 includes a plurality of second openings 210, second fixing openings 220, a recess 230, and a support 250.

Meanwhile, the plurality of second openings 210 may be arranged in alignment with the center of the second screen plate 200. The second openings 210 may be disposed corresponding to the positions of the first openings 110. [ When the first screen plate 100 and the second screen plate 200 are assembled, a portion where the first openings 110 and the second openings 210 are overlapped with each other is provided at the screening opening 350 (Figs. 6 and 7 ). ≪ / RTI >

The second fixing openings 220 may be disposed on both sides of the second screen plate 200. The second fastening openings 220 may have a circular shape and may be disposed corresponding to the first fastening openings 120. Accordingly, even if the first screen plate 100 changes its position along the first direction, the second fixing openings 220 can be entirely overlapped with the first fixing openings 120. [

On the upper surface of the second screen plate 200, a concave portion 230, which is recessed in the third direction, is disposed. In the third direction, the recess 230 does not overlap with the second openings 210 or the second fixing openings 220, and may extend along the first direction. The concave portion 230 may have a first width W1 along the second direction and may be deeper than the protruding height of the protrusion 130. [ The first screen plate 100 is fixed along the second direction when the protrusion 130 of the first screen plate 100 is aligned with the recess 230 of the second screen plate 200. [ The lower surface of the first screen plate 100 and the upper surface of the second screen plate 200 may be in close contact with each other. In the exemplary embodiments, a pair of recesses 230 may be disposed on the upper surface of the second screen plate 200, and they may be spaced from each other along the second direction.

The support portion 250 protrudes from one side of the second screen plate 200 along the third direction. On the other hand, in the support portion 250, a first adjustment opening 260 positioned corresponding to the first adjustment bolt 140 is disposed. That is, when the first screen plate 100 and the second screen plate 200 are assembled, the first adjustment bolt 140 passes through the first adjustment opening 260. On the other hand, a first adjusting nut 150 fastened to the first adjusting bolt 140 is disposed on the outer surface of the supporting part 250. That is, one side of the first screen plate 100 can be fixed to the support 250 of the second screen plate 200 as the first adjustment bolt 140 and the first adjustment nut 150 are fastened together . On the other hand, when the first adjusting bolt 140 and the first adjusting nut 150 are released, the first screen plate 100 can move along the first direction on the second screen plate 200.

The screen support plate 300 may be disposed on the side of the second screen plate 200 opposite to the support portion 250. In the screen support plate 300, the second adjustment opening 310 may be disposed at a position corresponding to the second adjustment bolt 142. That is, when the screen plate structure is assembled, the second adjusting bolt 142 passing through the second adjusting opening 310 can be fastened to the second adjusting nut 320, 100, one end of the second screen plate 200, and the screen support plate 300 may be fixed. On the other hand, when the second adjustment bolt 142 and the second adjustment nut 320 are released, the first screen plate 100 can move along the first direction on the second screen plate 200.

4 and 5, a method of adjusting the aperture of the screen plate apparatus according to an embodiment will be described.

4 shows a case where the first opening 110 of the first screen plate 100 (see FIG. 5) and the second opening 210 of the second screen plate 200 (see FIG. 5) . At this time, the selection opening 350 defined in the overlapping portion of the first opening 110 and the second opening 210 may have a relatively large size. Accordingly, the screen plate structure can sort relatively large particles.

Fig. 5 shows a case where the first screen plate 100 is moved in the first direction on the second screen plate 200. Fig. That is, the first adjusting nut 150 and the second adjusting nut 320 may be loosened to allow the first screen plate 100 to move along the first direction. Thereafter, the first screen plate 100 may be moved along the first direction so that the first opening 110 and the second opening 210 are partially overlapped, and the first adjusting nut 150 The second adjusting nut 320 can be tightened again so that the first screen plate 100 can be fixed on the second screen plate 200. [ As a result, the size of the screening aperture 350 can be reduced in comparison with FIG. 4, and the screen plate structure can sort relatively small particles.

According to exemplary embodiments, the screen plate structure may adjust the size of the screening aperture 350 as the first screen plate 100 is repositioned. That is, in the process of using the screen plate structure, when the particle size to be sorted is changed, the screen plate structure may not be replaced. Accordingly, the waiting time of the working process due to the change of the particle size can be minimized, and the working efficiency of the sorting process can be improved.

6 and 7, a method of adjusting the aperture of the screen plate device according to another embodiment will be described.

The first screen plate 102 and the second screen plate 202 shown in Figs. 6 and 7 each have a square first opening 112 and a second opening 212, each having a vertex pointing in the first direction, The first screen plate 100 and the second screen plate 200 described with reference to Figs. 2-5.

6 shows a case where the first opening 112 of the first screen plate 102 (see FIG. 7) and the second opening 212 of the second screen plate 202 (see FIG. 7) . At this time, the selection opening 352 defined in the overlapping portion of the first opening 112 and the second opening 212 may have a relatively large size.

Fig. 7 shows a case where the first screen plate 102 is moved in the first direction on the second screen plate 202. Fig. That is, the first opening 112 and the second opening 212 can be adjusted so as to be partially overlapped with each other, so that the size of the sorting opening 352 can be made smaller in comparison with FIG. However, since the first opening 112 and the second opening 212 each have a square shape having a vertex pointed toward the first direction, the selection opening 352 can always maintain a square shape. That is, even if the size of the screening aperture 352 is adjusted, the screening aperture 352 can have a square shape, so that the screen plate structure can classify particles of a desired size.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
