There is an advantage that it is easy to remove impurities or dust accumulated in the dispersion plate 500. When there are a plurality of distribution plates 500, the pair of rails may be configured in plural to correspond to the number of distribution plates 500.

4 is a coupling state diagram showing a coupling state of the blocking plate 530 according to an embodiment of the present invention.

Referring to FIG. 4, in one embodiment of the present invention, the distribution plate 500 may further include a blocking plate 530 coupled to the body 510 to block the distribution holes 520 step by step. have. The blocking plate 530 is disposed to be adjacent to the lower or upper portion of the distribution hole 520 in a plate shape to block the air passing through the distribution hole 520.

The blocking plate 530 is slidably moved while being inserted into the body 510 to block the plurality of distribution holes 520 step by step. For example, when the blocking plate 530 is completely inserted into the body 510, all the distribution holes 520 contacting the blocking plate 530 are blocked, and the blocking plate 530 is inside the body 510. The ratio of the open distribution holes 520 among the plurality of distribution holes 520 increases according to the degree of deviation from the.

In this case, the body 510 has a double structure, the dispersion hole 520 is provided on the upper and / or lower surface so that the degree of blocking is changed as the blocking plate 530 is inserted into the body 510.

In addition, the blocking plate 530 may be plural, and each of the blocking plates 530 may be slidably moved while being independently inserted into the body 510. As the plurality of blocking plates 530 are respectively coupled to one of the plurality of distribution plates 500, the opening and closing control of the plurality of distribution holes 520 provided in the distribution plate 500 is more easily performed. The plurality of distribution holes 520 may block the distribution holes 520 provided at a specific position.

In the present invention, by controlling the opening degree of the dispersion hole 520 step by step through the blocking plate 530 as described above, it is possible to easily adjust the blowing range and strength of the air in response to the state of the pulverized product or the sorting situation. For example, assuming that a pulverized product is supplied to the rear of the upper plate 100, the through hole 110 provided at the rear position of the upper plate 100 is dust when compared to the through hole 110 provided at the front position. However, it is easy to be closed by impurities, and it is necessary to increase the blowing force relatively. In this case, in the present invention, the dispersion hole 520 of the distribution plate 500 located at the rear side is opened, and only a part of the dispersion holes 520 of the distribution plate 500 are positioned at the front side to be positioned at the rear side rather than the front side. By increasing the amount of air passing through the distribution hole 520, the blowing intensity of the rear of the upper plate 100 can be increased than the front. The above method may be usefully applied even when a part of the through holes 110 is closed to partially open the closed through holes 110 by increasing the blowing intensity.

As another example, assuming that gangue moves to the left in the drawing and coal is moved to the right in the drawing according to the difference in the specific gravity of the crushed powder, the gangue has a high specific gravity and low fluidity compared to the coal, where the gangue is mainly distributed. There is a need to increase blowing intensity than at these mainly distributed positions. In this case, the distribution hole 520 located on the left side may be opened, and a portion of the distribution hole 520 located on the right side may be blocked to increase the blowing force on the left side than the right side.

Blocking the distribution holes 520 on the left, right, front and rear sides of the drawing may vary depending on the insertion direction of the blocking plate 530 in the body 510.

In more detail with reference to Figure 1, the gangue or rock in the pulverized movement in the left direction on the drawing, coal or coal is moved in the right direction on the drawing. The gangue or rock separated from the pulverized product does not require a separate blowing, but in the case of coal or coal, the speed of moving in the right direction on the drawing is increased by blowing, and in the present invention, among the distribution holes 520 of the distribution plate 500. The dispersion hole in the left direction in which the rock moves is blocked by the blocking plate 530, and the blowing hole and the right direction in which the coal moves are opened to concentrate the blowing intensity and range. In this case, the coal having concentrated blowing strength and range moves faster in the right direction in the drawing, thereby preventing the accumulation of pulverized material on the upper part of the upper plate 100, increasing the sorting amount of the pulverized material and reducing the energy of the blowing unit. can do.

As described above, in the present invention, even distribution of the dispersion holes 520 of the distribution plate 500 may be expected by zigzag arrangement with the through holes 110 of the upper plate 100. By adjusting the opening and blocking it can open the partially closed through hole 110 by adjusting the blowing range and blowing intensity. In addition, it is possible to assist the effective screening by reflecting the state of the initial pulverized product or the conditions of the screened coal or gangue, it is possible to increase the screening amount by adjusting the blowing range according to the position of the rock and coal.
