Description

Multi-screen sorter for particle size sorter {Multi-screen SORTER}

The present invention relates to a multi-screen sorter for a particle size sorter, and more particularly, to a multi-screen sorter for a particle size sorter for selecting the screening object for each particle size.

In general, a particle size sorter is a device for sorting a selection object including an ore and aggregate by particle size. The particle size selector is sequentially selected from a size having a large particle size while passing through screens having mesh eyes of different sizes.

However, as most sorting objects are formed in irregular shapes, clogging occurs due to pointed parts being caught in the mesh eyes of the screen, which causes the screening processing rate to drop and often stops sorting operations. The situation is accompanied by cumbersome work to be removed.

Therefore, in the conventional Patent Publication No. 2003-0054517, a flat iron and b flat iron are configured to overlap each other in an 'X' shape, and each of the points at which the a and b flat irons cross each other is riveted in a rotatable form. One end of the a flat iron is connected to the particle size sorting mat having a configuration connected to the one end of the cylinder, and the one end of the b flat iron is connected to the fastening arm of the tile side, and the protrusion or insertion of the cylinder rod is performed. By allowing the attack of the particle size selector to be adjusted, the particle size sorting function is improved to improve the quality of the sintered ore, thereby preventing the supply of defective quality to the post-process.

However, the particle size selector is a technique for controlling the attack according to the crossing angle of a, b flat iron, but many problems in use have been raised.

First, when the attack is controlled by the crossing angle of a, b flat iron, the width is reduced in the longitudinal direction, but as the width is extended in the transverse direction, the thinning and large particle size easily pass the sorting mat. Was followed by a decrease in lungs.

Secondly, a large number of a and b flat irons can be pivotally connected by rivets, as well as difficult to produce and require high precision as the malfunctions are preceded when the gaps between a and b flat irons connected by respective rivets are mismatched. Followed the problem.

Third, when a and b flat iron bends partially due to friction and impact with the screening object during the screening operation, a and b flat iron interferes on the horizontal line, thus preventing attack control.

Accordingly, the present invention has been conceived to solve the above problems, easy to remove the remaining screening object due to the jamming phenomenon during the screening operation, the screening size is precisely adjusted to improve the screening precision, durability by external impact It is an object of the present invention to provide an improved multi-screen sorter for a particle size sorter.

Features of the present invention to achieve this purpose, the fixed screen 10 is formed a plurality of first holes 12; A flow screen 20 installed to move up and down on the fixed screen 10 and having a plurality of second holes 22 formed therein; And the flow screen 20 is in close contact with the fixed screen 10, characterized in that the sorting hole 30 is formed in a common portion where the first, second holes 12, 22 overlap.

At this time, when the sorting material is caught on the sorting hole 30, the flow screen 20 is lifted, characterized in that the sorting material is provided to be removed through each of the first and second holes 12 and 22. .

In addition, the flow screen 20 is positioned in the horizontal direction, it characterized in that the size of the sorting hole 30 formed by the first, second holes 12, 22 is adjusted.

According to the above configuration and action, the present invention is the screening hole is formed in the common part of the first and second holes in a state in which the fixed screen and the flow screen is in close contact, even if the screening object is caught in the screening hole in the screening process lifting operation of the flow screen Independently extended through each of the first and second, the screening object sandwiched through the effect can be easily and simply removed.

In addition, since the size of the sorting hole is easily adjusted even during the sorting process by the horizontal position movement of the flow screen, the sorting grain size is easily set without stopping the grain size separator, and the sorting precision is improved.

Figure 2 is a block diagram showing an operating state of the multi-screen sorter for the particle size sorter according to an embodiment of the present invention.
Figure 3 is a block diagram showing a state in which the multi-screen sorter for the particle size sorter according to an embodiment of the present invention is installed in the particle size sorter.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The present invention relates to a multi-screen sorter for a particle size sorter, wherein the multi-screen sorter for a size sorter is easy to remove the remaining sorting object due to the jamming phenomenon during the sorting operation, the sorting size is precisely adjusted to improve the sorting precision, In order to improve the durability by the external shock is made of a main configuration, including a fixed screen 10, the flow screen 20, the sorting hole (30).

In the fixing screen 10 according to the present invention, a plurality of first holes 12 are formed. The fixed screen 10 is arranged to arrange a plurality of first holes 12 on the plate, wherein the first hole 12 is shown in a rectangular shape in Figure 1, but is not limited to this, long hole, round, triangular, pentagon It is possible to change the shape to include, hexagon, octagon.

The fixed screen 10 is installed at an end portion of a conveying means including a conveyor for supplying a sorting object on a particle size sorter, and the sorting object introduced onto the fixed screen 10 is not separated from the outside during the sorting process. It is preferable that a hopper is provided.

In addition, the fixed screen 10 is installed in the particle size sorter is installed so as to generate a vibration force or the left and right reciprocating transfer by the vibration device with the distribution screen 20 to be described later depending on the screening target.

In addition, the flow screen 20 according to the present invention is installed to move up and down on the fixed screen 10, a plurality of second holes 22 are formed. The flow screen 20 is installed to be moved upward and downward by a transfer member including a cylinder, a screw, a rack, and a pinion on an upper portion of the fixed screen, and a hopper at an edge portion to prevent external separation of the sorting object during the sorting process. Is provided.

In addition, although the second hole 22 is formed in the same shape and size as the first hole 12 in FIG. 1, the shape and the size may be changed differently from each other under the same arrangement interval.

In addition, the sorting hole 30 is formed in a common portion in which the first and second holes 12 and 22 overlap with the floating screen 20 seated on the fixed screen 10. That is, as shown in the enlarged view of FIG. 1, the first and second holes 12 and 22 are formed in a quadrangular shape, and the “b” shaped one corners of the first hole 12 and the second holes 22 are formed. The "x" shaped selection hole 30 is formed by the "a" shaped one side edge portion.

As such, the sorting hole 30 formed by the common part of the first and second holes 12 and 22 is formed in a smaller size than the first and second holes, so that the sorting object is caught in the sorting hole 30 during the sorting process. As shown in FIG. 2, when the flow screen 20 is elevated, the first and second holes 12 and 22 of the expanded size are spaced apart from the sorting hole 30 so that the sorting object caught in the sorting hole 30 is first. , Through the two holes (12) (22) has the advantage of being easily removed.

On the other hand, the fixed screen 10 and the flow screen 20 flows with the fixed screen 10 in a plurality of places by connecting the horizontal bar and the longitudinal bar as shown in Figure 2 so as to prevent sag and bending by the weight of the screening object Preferably, the screen 20 is provided to support the screen 20.

In addition, the flow screen 20 is positioned in the horizontal direction, it is provided to adjust the size of the sorting hole 30 formed by the first, second holes 12, 22. The flow screen 20 is conveyed in a horizontal direction (eg, X-axis, Y-axis) by a conveying member including a cylinder, a screw, a rack and a pinion, wherein the flow screen 20 is the first and second as shown in FIG. When the holes 12 and 22 are formed in a quadrangular shape, the holes 12 and 22 are simultaneously moved in the X and Y axes so that the selection holes are reduced or expanded at the same ratio in the horizontal and vertical directions.

Thus, when configuring a device for selecting the screening step by step by placing a plurality of multi-screen sorter in multiple stages, as shown in Figure 3, even if the sorting holes formed in the multi-screen sorter for each step is not processed to different sizes, By applying the fixed screen 10 and the flow screen 20 of a single standard, the size of the sorting hole 30 is varied by adjusting the position of the flow screen 20 in the XY axis direction. It is easy to configure the device.

In addition, since the position of the flow screen 20 is adjusted from time to time during the screening process, it is easy to adjust the screening size of the screening object, and there is an advantage that the screening precision is improved.

On the other hand, as the multi-screen sorter is formed in a double plate shape in a state in which the fixed screen 10 and the flow screen 20 are stacked, durability by external impact is improved.
