Description

High-efficiency energy-saving sieve with spiral positioning screen

The invention relates to a screening screen, in particular to a high-efficiency and energy-saving screen screen capable of arranging spirally.

There is a screening network (TW certificate No. I314172 patent case), which includes most positioning rings and most of the sieve bars fixed to the positioning rings. The positioning rings are spaced along an axis and each has an inner ring surface and Most of the recesses recessed by the inner annular surface, each of the sieve bars has a root that can be embedded in the recesses, a body connected to the root, and a body opposite to the root and connected to the body In the head of the machine, most of the sieve holes can be formed together by using the positioning rings and the sieve bars.

Although this screening net can achieve the desired screening purpose, when manufacturing, most of the straight bar-shaped blanks and these sieve bars are prepared, and most of the caulks are opened on one side of the blanks. The roots of these sieve bars are then embedded in the cavities. Finally, a roll mill is used to wind the green material that has been passed through the sieve bar into a hollow ring, and is carried out at the opposite end of the green material. These positioning rings can be formed separately by welding.

The production speed of such screening nets is slow, and the production capacity cannot be increased.

Therefore, the object of the present invention is to provide a highly efficient and energy-saving screen with a spirally positioned screen bar that can be manufactured quickly and can increase the production capacity.

Therefore, the high-efficiency and energy-saving screen of the present invention capable of spirally positioning the screen bar includes a hoop unit, a plurality of screen bars and a plurality of screen holes. The hoop unit extends along an axis and can be formed to form a sieve filtering space. The hoop unit is formed by a continuously extending hoop and spirally surrounds the axis. The hoop has an adjacent filtering screen. The inner ring surface, the sieve bars are parallel to the axis and are fixed to the hoop unit, respectively, and each has a fixed end fixed to the inner ring surface and an opposite end to the fixed end and extended on Each of the heads and fixed ends in the sieve filtering space has a joint portion fused to the inside of the inner annulus and fused with the hoop, and the sieve holes are respectively formed on the hoop and the Wait between sieve bars.

The effect of the present invention is that the hoop of the hoop unit extends spirally, and after the hoop is fixed to the fixed ends of the screen bars, the hoop unit and the screen bars can be firmly connected. The overall structure of the screen has good strength and rapid manufacturing, which can increase production capacity.

Referring to FIG. 1 to FIG. 4, an embodiment of a high-efficiency and energy-saving screen of a spirally positionable screen bar according to the present invention includes a hoop unit 10, a plurality of screen bars 20, and a plurality of screen holes 30.

The hoop unit 10 extends along an axis L and can be formed to form a sieve filtering space 11. The hoop unit 10 is formed by a continuously extending hoop 12 and spirally surrounds the axis L. The hoop 12 has a Adjacent to the inner annular surface 121 of the filtering space 11, the inner annular surface 121 is V-shaped in cross section parallel to the axis L, and has a tip portion 122.

The sieve bars 20 are parallel to the axis L and fixed to the hoop unit 10, respectively, and each has a fixed end portion 21 fixed to the inner ring surface 121 and a fixed end portion 21 opposite to the fixed end portion 21 and extended. In the head 22 in the filtering space 11, the fixed ends 21 each have a joint portion 211 that can be fused into the inside of the tip portion 122 of the inner annular surface 121 and fused with the hoop 12. The cross-sectional shape of the joint portions 211 of the fixed ends 21 perpendicular to the axis L is V-shaped. Each of the heads 22 has a connecting portion 221 connected to the fixed end portion 21 and a sieve filtering surface 222 opposite to the connecting portion 221, and gradually expands from the connecting portion 221 toward the sieve filtering surface 222. shape.

The screen holes 30 are respectively formed between the hoop strip 12 and the screen strips 20.

Therefore, in the present invention, the high-efficiency and energy-saving screen of a sieve can be positioned spirally, the hoops 12 of the hoop unit 10 are continuously extended in a spiral shape, and the inner ring surface 121 is used to provide the welding portions 211 of the sieve bars 20 for welding The screen holes 30 can be formed between the hoop strip 12 and the screen strips 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 preform 12 'that has not been rolled and is in the shape of a straight bar are prepared. The jig 40 is in the shape of a hollow cylinder. And has an outer peripheral surface 41, two end planes 42 perpendicular to the outer peripheral surface, and most of the recesses 43 recessed from the outer peripheral surface 41 and communicating with the end planes 42 in the axial direction, and the cross-sectional shapes of the recesses 43 The cross-sectional shape of the head 22 of the sieve bars 20 is adapted to be wide inside and narrow outside.

Then, the heads 22 of the sieve bars 20 are respectively penetrated from one end plane 42 of the sieve bars 20 into the recesses 43 so that the fixed ends 21 protrude from the outside of the outer peripheral surface 41.

Continuing, as shown in FIG. 6, using a rolling device 50, the hoop blank 12 ′ surrounds the jig 40 and the screen bars 20 inserted in the jig 40. The hoop blank 12 ′ will The rolled hoop 12 is rolled into a spiral shape. Subsequently, the welding equipment 60 provided on the side of the rolling equipment 50 welds each of the sieve bars 20 and the spiral hoop 12 to make the joint portions 211 of the sieve bars 20 and the hoop. The tip portion 122 of the inner ring surface 121 of 12 is fused together, and the screen bars 20 and the hoop unit 10 are welded and fixed. By virtue of the V-shaped cross-section of the tip portion 122 of the hoop strip 12 and the V-shaped cross-section of the joint portion 211 of the sieve strips 20, it can be easily fused into one body during welding.

Finally, the hoop strip 12 that has been welded into one body and the screen strips 20 are separated from the fixture 40, and the high-efficiency and energy-saving screen screen of the spirally positionable screen strip of the present invention can be obtained (see Figures 1, 2 and Figures) 3).

Therefore, the present invention is relatively easy to manufacture, has a fast manufacturing speed, and can increase production capacity.

In summary, the high-efficiency and energy-saving screen of the present invention can be positioned spirally, and the overall structure is simple, easy to manufacture, and the overall structural strength is good after it is made, which can indeed achieve the purpose of cost invention.

However, the above are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
