Description

[Detailed description of the invention] [Field of industrial application] This invention is installed above the material input port of a solid material conveyor such as a flight conveyor or bucket conveyor, and is used to remove long string-like objects such as strings and wires. The present invention relates to a string-like object removing device.

[Conventional technology]

Conventionally, when processing solid waste, for example, even if shredding is performed, cloth, plastic film, etc. are difficult to cut and tend to remain as string-like materials. Conventionally, no special measures have been taken when such solid waste is transported by, for example, a flight conveyor.

[Problem that the invention attempts to solve]

It became entangled with the flight or bucket, causing trouble. FIG. 1a shows a flight conveyor, in which a chain 3 having a large number of flights 2 circulates through a casing 1, and material to be treated is inputted from an input port 4 and discharged from an outlet 5. . Some of the string-like objects 6 among the items being handled straddle the flight 2 near the input port 4 and are lifted up as they are, and some do not fall even at the exit 5, and further become entangled with the flight 2 when the flight 2 is reversed. , it returns to the vicinity of the input port 4 again without leaving. Furthermore, other string-like objects 2 may become tangled, which has the disadvantage of accumulating and causing the conveyor to stop.

In FIG. 1b, a bucket 13 is driven by a chain 12. On the other hand, a mesh screen is sometimes placed to remove string-like objects from the objects being handled, but this has the drawback that it takes time and effort to remove the string-like objects entangled with the screen.

Comb-shaped screens with one end open are also seen, but string-like objects that extend parallel to the comb teeth pass through the screen and cannot be captured.
There was a problem.

The present invention eliminates the above-mentioned drawbacks of the conventional ones, effectively removes string-like objects from objects to be handled, and can easily remove string-like objects from the screen bar, even after passing through a set of screens. It is an object of the present invention to provide a string-like material removal device that can be captured by the following screen.

[Means for solving problems]

As a means to solve the above-mentioned problems, the present invention is equipped with a plurality of sets of screen bar units each having a plurality of long screen bars held in parallel with one end open above the material input port of a solid material conveyor. To provide a string-like object removing device characterized in that each unit is arranged with a height difference in the vertical direction, and the screen bars of vertically adjacent units are arranged in different directions. It is.

〔Example〕

To explain the present invention with reference to the drawings, FIGS. 2A, 2B, and 2C show a set of screen bar units 10, 7 being screen bars made of round bars or pipes arranged in parallel, One end is attached to a fixture 8, while the other end is opened to form an open end 9. When an object is thrown into such a removing device from above, the string-like object 6 gets caught on the screen bar 7 and does not fall downward. To remove the string-like material 6, it can be easily removed from the open end 9 by sliding it on the screen bar 7 toward the open end 9.

Such screen bars 7, 7', fixtures 8,
8', two sets of screen bar units 10,
10' is arranged on the input port 4 as shown in FIGS. 3a and 3b, one screen bar unit 10 is supported above the other screen bar unit 10' with a certain height difference, and the screen bar 7 and 7' are arranged so that they are not parallel but in different directions.
Even if a string-like object oriented parallel to the upper screen bar 7 passes through the upper screen bar 7, it can be caught by the lower screen bar 7'. Units with three or more stages may also be used.

4a, b, and c show another embodiment of the screen bar unit, in which the screen bar 7 is in the form of a flat plate. The top surface of the screen bar 7 is sloped gradually downward toward the open end 9.
The string-like object 6 hanging on the screen bar 7 gradually moves toward the open end 9 due to its own weight. This movement can be made easier if the screen bar 7 is vibrated. The screen bar 7 may be a round bar or a pipe arranged at an angle. Two sets of such screen bar units 10 are stacked and arranged as shown in FIG.

This invention uses multiple screen bars in parallel.
Moreover, by stacking the units held with one end open so that the screen bars are not parallel to each other, even a string-like object that passes through a set of screen bar units can be reliably captured and handled. It is possible to provide a string-like object removing device that reliably removes string-like objects from inside the screen bar and also easily removes the string-like objects from the screen bar.
It can produce extremely great practical effects.
