DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and a method for manufacturing a conical drum screen according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view showing a state that a wire is wound around a support bar constituting a conical drum screen according to a preferred embodiment of the present invention, and FIG. 4 is a front view of a conical drum screen according to a preferred embodiment of the present invention.

3 to 4, the drum screen 10 according to the present invention includes a support bar 11, and a wire 12.

In particular, the drum screen 10 of the present invention has a conical shape whose overall shape is reduced from one end to the other end, and is composed of a plurality of support bars 11 arranged to be spaced apart from each other by a predetermined distance in a conical shape; And a wire 12 (12) formed on the outer side or the inner side of the support bar 11 and fused while being spirally wound while maintaining a gap along the longitudinal direction of the support bar 11 and having spacing protrusions 12b protruded laterally on one side or both sides thereof And the minimum spacing of the wires 12 is secured by the spacing protrusions 12b.

That is, the wire 12 is formed to have a long length and is wound on the outer side of the support bar 11 a plurality of times in a helical shape with a predetermined gap.

One wire 12 may be wound all over the support bar 11 or two or more wires 12 may be continuously supplied and wound.

Scratches 12a having the same depth and size are formed at regular intervals on the wire 12 and spacing protrusions 12b protrude from both sides of the wire 12 on both sides of the scratch 12a.

The size of the spacing protrusions 12b is the same.

When the wire 12 is spirally wound on the support bar 11, the gap is automatically controlled.

However, in the process of fusing the wire 12 and the support bar 11 by welding, the fused portion may be thermally expanded to narrow the interval between the spirals.

In this case, the thermally expanded spiral portion is deformed until it comes into contact with the spacing projection 12b formed on the neighboring spiral portion, but after the spacer projection 12b is contacted, the spacing projection 12b prevents deformation , The gap between the spiral portions can be secured by the size of the spacing projection 12b.

Therefore, the drum screen of the present invention can maintain the filtering function.

5 is a view showing a state in which wires are wound and fused to the support bars.

The support bar 11 has a rectangular cross section and a weld portion 11a in the form of a wedge is formed on an outer surface of the support bar 11 that is in contact with the wire 12 before being welded to the wire 12.

FIG. 6 is a bottom view of the wire, and FIG. 7 is a cross-sectional view showing a state in which the support bar is spirally wound with wires at regular intervals.

The cross section of the wire 12 has a wedge shape in a triangular shape and extends outward when the support bar 11 is wound around the outside at regular intervals.

Due to such a winding structure, the drum screen according to the present invention has a form of filtering out foreign substances while introducing water from the outside to the inside.

On the contrary, in the case of the drum screen having the form in which the wire 12 is widened toward the inside, foreign matters are drained while discharging the water from the inside to the outside.

Scratches 12a having the same size are formed at regular intervals on the wire 12 and spacing protrusions 12b are formed on both sides of the scratch 12a to protrude laterally of the wire 12.

The interval protrusion 12b is formed by squeezing the portion to be pressed in the process of pressing the soft wire 12 to form the scratch 12a.
