It is supported by a guiding device 14 having 2,13.

Further, the lower conveyor belt 2 is extended at the lower horizontal portion 3C of the opposing portion 3, and the input port 1B is configured to drop the scattering material 9 onto the extended portion 15 and supply it between the conveyor belts 1 and 2. Further, at the end of the upper horizontal part 3B of the opposing part 3, a receiving opening 17 is provided for receiving the scattering materials 9 conveyed by the conveyor belt 1.2. In the figure, 1° and 2° indicate the return portion of the conveyor belt 1.2.

When the conveyor belts 1.2 are driven so that the facing portion 3 moves upward at the same speed as shown by the arrows in FIG. 9, both width ends 7.8 are pressure rollers 10. The conveyor belt 1.2 is accommodated in the closed conveyor belt 1.2 by pushing it apart against the pressing force of the pressing roller 12.13 (from the state shown in FIG. 7 to the state shown in FIG. 8). state), and is fed into the receiving port 17 via the lower horizontal portion 3C1, the upward conveyance portion 3A, and the upper horizontal portion 3B while being subjected to the pressing force of the pressing rollers 12 and 13.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional upward conveyor, when conveying hard materials 9 such as crushed stone or coal upward, the required tension and the pressure as shown in Fig. 7.8 are required. Guidance device! Since it is necessary to convey the conveyor belt 1.2 while applying the pressing force of 14 to the conveyor belt 1.2, only one side of the conveyor belt 1.2, especially on the side of the scattering material 9, is used under harsh conditions. Abnormal wear on one side of the conveyor belt 1.2 significantly shortens its lifespan, necessitating replacement within a short period of time.

In addition to the above-mentioned upward conveyor, there are also devices for dehydrating sludge, etc., or dewatering devices for papermaking materials in papermaking machines, etc.
In an apparatus that dewaters a muddy substance by holding it between a conveyor belt and conveying it under pressure, there is a problem that the side of the conveyor belt that comes into contact with the guide roller is quickly worn out and damaged.

The present invention was made by focusing on the above-mentioned conventional problems.
The purpose of this invention is to extend the life of the conveyor belt in a belt conveyor device that conveys crushed materials or muddy substances while being held under pressure by the conveyor belt.

[Means for Solving the Problems] The present invention provides a belt conveying device in which scattered materials, muddy substances, etc. are held and conveyed by a conveying belt, in which a part of the conveying belt is provided with a twisted part. The present invention relates to a belt conveying device characterized in that an endless Möbius strip is formed.

[Function] Since the conveyor belt is twisted to form an endless Möbius strip, the entire surface of the conveyor belt receives uniform wear, thereby extending the life of the conveyor belt.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows one embodiment of the present invention, and the parts in the figure with the same reference numerals as in FIG. 6 represent the same parts.

FIG. 1 shows return sections 1' and 2' of two endless conveyor belts 1.2 in the upward conveyor shown in FIG.
