The invention relates to a screening net, in particular to a highly efficient and energy-saving screen which can be spirally positioned.

There is a screening network (TW No. I314172), which comprises a plurality of positioning rings and a plurality of screening bars fixed to the positioning rings, the positioning rings are arranged along an axis, and each has an inner annular surface and a plurality of recesses recessed by the inner annular surface, each of the screen strips having a root portion that can be embedded in the recessed groove, a body connected to the root portion, and a body opposite to the root portion and connected to the body portion The heads are matched with the screen bars by the positioning rings to form a plurality of mesh holes.

Although the screening mesh can achieve the intended screening effect, in the manufacture, most of the straight rod-shaped embryo materials and the sieve strips are prepared, and after a plurality of cavities are formed on one side of the embryonic materials, Then, the roots of the sieve strips are embedded in the recessed grooves. Finally, the blank material having the sieve strips is wound into a hollow ring shape by a roll mill, and is carried out at opposite ends of the embryo material. By welding, the positioning rings can be formed separately.

This screening network is slow to manufacture and capacity cannot be improved.

Accordingly, it is an object of the present invention to provide an energy efficient screen for a spirally positionable screen that is fast and can increase productivity.

Thus, the highly efficient and energy-saving screen of the spiral positioning screen of the present invention comprises a hoop unit, a plurality of screen bars and a plurality of screen holes. The hoop unit extends along an axis and is formed around a screen space formed by a continuously extending band and spirally surrounding the axis, the band having an adjacent filter space The inner ring faces are parallel to the axis and are respectively fixed to the hoop unit, and respectively have a fixed end fixed to the inner ring surface and a opposite end opposite to the fixed end portion a head portion of the screen space, each of the fixed end portions having a joint portion fused to the inner side of the inner annular surface and fused to the hoop strip, the screen holes being respectively formed on the hoop strip and the Wait between the sieve bars.

The utility model has the advantages that the hoop strip of the hoop unit is spirally extended, and the hoop strip is welded to the fixed end portions of the screen strips to stably fix the hoop unit and the screen strips. The overall structural strength of the screen is good and the manufacturing is fast, which can increase the production capacity.

Referring to Figures 1 through 4, an embodiment of the energy efficient screen of the spirally positionable screen of the present invention comprises a hoop unit 10, a plurality of screen bars 20 and a plurality of screen openings 30.

The hoop unit 10 extends along an axis L and is formed around a screen space 11 formed by a continuously extending band 12 and spirally surrounding the axis L. The band 12 has a Adjacent to the inner annular surface 121 of the sieve space 11, the inner annular surface 121 has a V-shaped cross-sectional shape parallel to the axis L and has a tip end portion 122.

The screen bars 20 are parallel to the axis L and are respectively fixed to the hoop unit 10, and have a fixed end portion 21 fixed to the inner ring surface 121 and an opposite end to the fixed end portion 21 In the head portion 22 of the screen space 11, the fixed end portions 21 each have a joint portion 211 which is melted into the inner side of the tip end portion 122 of the inner ring surface 121 and is integrally welded to the band 12 . The joint portion 211 of the fixed end portions 21 has a V-shaped cross-sectional shape perpendicular to the axis L. The heads 22 each have a connecting portion 221 connected to the fixed end portion 21 and a screening surface 222 opposite to the connecting portion 221, and are gradually enlarged when the connecting portion 221 extends toward the screening surface 222. shape.

The screen holes 30 are formed between the band 12 and the screen bars 20, respectively.

Therefore, the high-efficiency energy-saving screen of the present invention can be spirally positioned, and the hoop strip 12 of the hoop unit 10 is continuously extended in a spiral shape, and the inner ring surface 121 is used to provide the joint portion 211 of the screen strip 20 to be welded and fixed. The mesh holes 30 can be formed between the hoop strip 12 and the screen bars 20, and the overall structure is simple.

As shown in FIG. 5, at the time of manufacture, a jig 40, the sieve bars 20, and a hoop blank 12' which has not been rolled and has a straight strip shape are prepared, and the jig 40 has a hollow cylindrical shape. And having an outer peripheral surface 41, two end planes 42 perpendicular to the outer peripheral surface, and a plurality of recesses 43 recessed by the outer peripheral surface 41 and communicating in the axial direction to the end planes 42, the cross-sectional shape of the recesses 43 The cross-sectional shape of the head 22 of the screen 20 is matched, and is narrow inside and wide.

Then, the heads 22 of the screen strips 20 are inserted into the cavities 43 from the one end plane 42 and the fixed end portions 21 are protruded from the outside of the outer peripheral surface 41.

Continuing, as shown in FIG. 6, the hoop blank 12' is surrounded by the jig 40 and the slats 20 embedded in the jig 40 by a rolling device 50. The hoop 12 is rolled and bent into a spiral shape. Subsequently, the welding device 60 disposed on one side of the rolling equipment 50 welds each of the screen bars 20 to the spirally wound band 12 so that the joint portion 211 of the screen bars 20 and the band The tip end portion 122 of the inner annular surface 121 of 12 is fused integrally, and the screen bars 20 are welded and fixed to the hoop unit 10. The tip end portion 122 of the hoop strip 12 has a V-shaped cross section, and the joint portion 211 of the screen strips 20 has a V-shaped cross-sectional shape, and can be easily sintered integrally during welding.

Finally, the welded hoops 12 and the slats 20 are detached from the jig 40, and the highly efficient and energy-saving screen of the spiral locating screen of the present invention can be obtained (see FIG. 1, FIG. 2 and FIG. 3).

Therefore, the manufacturing of the present invention is relatively easy, the manufacturing speed is fast, and the productivity can be improved.

In summary, the high-efficiency energy-saving screen of the spiral positioning screen of the invention has the advantages of simple overall structure, easy manufacture, and good overall structural strength after manufacture, and can indeed achieve the object of the present invention.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
