Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to an anti-adhesion net for a vibrating sieve that does not cause clogging due to adhesion of powdered material to the screen surface. .

<Prior art and its problems> A screen for a vibrating sifter is used by attaching it to the sifter body, and usually hook-shaped fittings are connected to both sides of the screen itself, and these fittings are attached to the screen itself. It has a structure that is attached to the sieving machine body. For example, the configuration is as shown in FIGS. 1 to 3 of Japanese Utility Model Publication No. 54-45256, or as shown in FIG. 4 to prevent the mesh from becoming loose. That is, conventionally, in order to create a structure in which the net does not loosen as much as possible, emphasis has been placed on connecting the net and the fixtures as strongly as possible. It is true that if the net becomes loose, as shown in the above-mentioned Utility Model Publication No. 54-45256, the net will flap and constantly come into contact with the tip of the support frame on the back, damaging the net. Therefore, as mentioned above, it is important to prevent the net from becoming loose.

However, no matter how long the lifespan of a screen is, it cannot be said to be useful unless it is used for sufficient sifting work, and as a screen for a sifting machine, it is important to make sure that it does not become clogged during use. If this happens, the sieving efficiency will be significantly reduced. By the way, various types of nets such as those shown in the above-mentioned Japanese Utility Model Publication No. 54-45256 are susceptible to clogging because tension is applied to the wires that constitute the net. The more tension you put on the net itself, the stronger the net will be fixed.
As a result, the powder adheres to the mesh without causing any flapping in the mesh itself. This adhesion of powder is even more severe when the object to be treated is wet, and temporarily it even loses its sieving effect. Therefore, there are methods in which a tapping ball is placed under the net so that it can move up and down, and the attached material is dropped and removed by the impact of the tapping ball, or a heavy object such as a chain is placed on the surface of the net and its vibration is removed. Methods such as hitting the surface of the net with a hammer have been considered, but currently none of these methods are very effective considering the amount of damage to the net.

The object of the present invention is to provide a net that does not cause wear and tear and does not become clogged with the powdery material.

<Means for solving the problem> The means for achieving the above objective are as follows. That is, the net body is mounted and joined to the top of a plurality of pipes made of flexible materials such as plastic or rubber that are opened at both ends and arranged approximately parallel to each other at required intervals, and each pipe is connected to the inner wall of the pipe. Insert a core material such as a wire or wire rope that has an outer diameter large enough to create a gap between them, make both ends of the core material protrude from both ends of the pipe, and attach the protruding parts of both ends of the core material directly or with hook fittings, etc. This anti-adhesion net for a vibrating sieve is characterized in that it is connected to the sieving machine main body via a tool, and the pipe and the net main body integrally connected thereto are not connected to the sieving machine main body.

In this case, it is effective to make the core material sufficiently smaller than the inner diameter of the pipe because it can cause the net to flutter even more.

<Embodiments and operations> The net of the present invention will be described in detail below with reference to drawings showing embodiments thereof.

The net of the present invention is composed of a net main body 1, a pipe 2 attached to the back side of the net main body, and a core material 3 inserted into the pipe. The net body 1 is not particularly limited, and may be made of ordinary metal or one whose surface is coated with plastic or rubber. As shown in FIGS. 1 and 2, pipes 2, 2, . . . are attached to the back surface of such a net main body 1 in a substantially parallel manner at appropriate intervals. This pipe 2
is made of a flexible and preferably elastic material such as plastic or rubber, into which a core material 3 such as a wire or wire rope is inserted, with both ends protruding.

The core material 3 is configured to be able to move freely within the pipe 2, and preferably has an outer diameter that is sufficiently smaller than the inner diameter of the pipe 2, the reason for which will be explained later. Both protruding ends of the mesh core material 3 having such a structure are joined to a fitting 5 for attachment to the sieving machine main body 4, as shown in FIG. 3, for example. In FIG. 3, the net body 1 is not directly connected to the fixture 5, and therefore, when it is attached to the sieving machine body 4 under considerable tension, the tension is not directly applied to the net body 1. There is nothing to join.

Note that the gist of the present invention is to connect the core material inserted into the pipe to the sieving machine body, so the core material is directly connected to the sieve machine body instead of using a fitting as in the above embodiment. This also includes cases where

As can be seen from the structure shown in the above-mentioned embodiments, the net of the present invention is connected to the sieving machine body through the core material and not through the net body, so there is no tension on the net body, and therefore it is difficult to use. In this case, the net itself can perform a flapping motion on its own. The flapping motion becomes even more effective when the core material inserted into the pipe is sufficiently smaller than the inner diameter of the pipe, since the flapping motion is allowed to increase by the gap. In the net of the present invention, the net moves up and down finely due to the above-mentioned flapping motion,
Because of the pipe, there is no direct contact between the net body and the lower support frame, which prevents damage to the net body.

<Effects of the invention> As explained above, the net of the invention has no tension applied to the net itself, so the net itself can vibrate or flutter on its own during use. Vibration can prevent powder from adhering and improve sieving efficiency.
