Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial application field" The present invention relates to a screen used in a contra-wave vibrating screen machine.

"Prior Art" The conventional contra-wave net can be sufficiently used as a sifting net for a lightweight net product without clogging. However, the width of the slit gap between the horizontal strands is difficult to be kept constant, and the collapse of the horizontal strands is quick, and there is no wear of the horizontal strands themselves, but they cannot be used. Therefore, crimp the flat wire or round wire of the horizontal wire and fix the slit gap (mesh) with the crimp, or press the upper part of the horizontal wire with a vertical rubber strip to fix the mesh. There are many things. In the case where the slit gap (mesh) is fixed by the crimp, the horizontal strands jump upwards, which easily causes collapse and prevents the horizontal strands from jumping up due to vibration even if they are pressed by the vertical rubber strips. It was difficult to get along with. In addition, a wire mesh was developed in which horizontal strands were woven with two warp woven lines, and the upper and lower parts of the horizontal strands were vertically covered with abrasion-resistant materials such as rubber along this warp woven line. Divides the wear-resistant material into the slit gap and the outer circumference of the horizontal strands to the left and right, and the warp woven lines are easily broken by the vibration friction between the warp woven lines and the horizontal strands, which makes it difficult to maintain the slit gaps. There was a problem that it is easy for the eyes to collapse (Acts 62-7)
431).

[Problems to be solved by the invention] The purpose of the present invention is to obtain a contra-wave vibrating screen mesh which keeps the width of the slit gap between the horizontal strands constant and has few collapses.

"Means for solving the problem" The present proposal is that in a vibrating screen mesh in which a plurality of horizontal strands are stretched at right angles to the flow direction and a slit gap for sieving is interposed between the horizontal strands, Urethane vertical materials facing each other are arranged above and below the horizontal strands, and the upper and lower vertical materials are welded to each other continuously over the entire width of the welded portion in the horizontal direction, and the slit gap and the entire circumference of the horizontal strands. And a vertical reinforcing wire in the flow direction is stretched on the lower surface of the horizontal wire, and the reinforcing wire is embedded in the lower material to form a contra-wave network. To be done.

[Operation] Accordingly, the horizontal strands 2 are arranged on the vibrating screener at right angles to the flow direction a of the objects to be sorted to support the screen. Then, when the vibrating screener is operated, the horizontal strands 2 are made of urethane, and the vertical vertical material 1,
1 vibrates up and down integrally with 1 and with respect to the operation in the flow direction a, operates integrally with the welded portion 1'in the slit gap t,
Moreover, in the above-mentioned vibration in the up-and-down direction, the vertical reinforcing wire 3 has a plurality of horizontal strands 2.
The horizontal wire 2 is restrained from jumping up by exerting the action of pulling the wire downward.

"Example" A contra that has a plurality of horizontal stainless steel strands 2 stretched at right angles to the flow direction a, and a slit gap t for sieving is interposed between the horizontal strands 2. In the tave vibrating screen, the urethane vertical materials 1, 1 facing in the flow direction a
Are arranged above and below the horizontal strand 2, and the same strands 1 and 1 are welded together by heating to fill the slit gap t and the outer periphery of the horizontal strand 2 with the welded portion 1 '. . As shown in FIG. 2, such vertical materials 1 and 1 have a plate-shaped vertical material 1a and a linear vertical material 1b arranged in parallel between them. A vertical reinforcing wire 3 made of stainless steel in the flow direction a is stretched on the lower surface of the horizontal wire 2, and the reinforcing wire 3 is embedded in the lower vertical material 1.
The same line 3 is embedded in the linear vertical material 1b as shown in FIG. 2, but can be embedded in the plate-shaped vertical material 1. However, a warp weaving wire for weaving the horizontal strands 2 in the longitudinal direction must not be embedded inside the above vertical materials 1a, 1b.

[Effect] Since the present invention is constructed as described above, the slit gap t for screening between the horizontal strands 2 and 2 and the outer periphery of the horizontal strand 2 are filled with the welded portion 1'of the urethane vertical material 1, 1. With the gap t kept constant, the vertical materials 1 and 1 are integrally adhered to the outer periphery of the horizontal wire 2, and the vertical materials 1 and 1 and the vertical reinforcing wire 3 vibrate in cooperation with the horizontal wire 2. The change of the above-mentioned gap t due to the jumping up of the horizontal strands 2 can be suppressed to prevent the collapse of the mesh, and the benefit of being able to be sufficiently used as a sieving net without clogging even on a relatively heavy net product. is there.
