The specific embodiment
To do to describe in detail further to the embodiment of the invention below.
The present invention can two-way haul combined belt conveyer, its preferable specific embodiment is:
The supporting construction of its upper and lower branch load-transfer device is different types of carrying roller or air cushion.
The carrying roller of selecting following several kinds of different structures for use is respectively as the supporting construction of upper and lower branch load-transfer device: load-transfer device takes the shape of the letter U, and is supported by the U-shaped carrying roller; It is tubular that load-transfer device is, and supported by the tubulose carrying roller; Load-transfer device is flute profile, is supported by the flute profile carrying roller; Load-transfer device is flute profile, is supported by air cushion.Different supporting way combinations through several kinds of upper and lower branch load-transfer devices form five kinds of compound type belt conveyers, can utilize upper and lower branch while or timesharing to carry variety classes and varying number material to both direction.
As shown in Figure 1, top set's load-transfer device takes the shape of the letter U, and is supported by the U-shaped carrying roller; The inferior division load-transfer device is tubular, is supported by the tubulose carrying roller;
As shown in Figure 2, top set's load-transfer device is tubular, is supported by the tubulose carrying roller; The inferior division load-transfer device takes the shape of the letter U, and is supported by the U-shaped carrying roller;
As shown in Figure 3, top set's load-transfer device takes the shape of the letter U, and is supported by the U-shaped carrying roller; The inferior division load-transfer device is flute profile, V-arrangement or U-shaped, is supported by corresponding carrying roller;
As shown in Figure 4, top set's load-transfer device is flute profile, is supported by the flute profile carrying roller; The inferior division load-transfer device is tubular, is supported by the tubulose carrying roller;
As shown in Figure 5, top set's load-transfer device is supported by air cushion by being flute profile; The inferior division load-transfer device is tubular, is supported by the tubulose carrying roller.
Mentality of designing of the present invention is:
Upper and lower branch load-transfer device is chosen the various supports mode, makes the section of load-transfer device form different shapes, with the size that satisfies traffic capacity and the requirement of material characteristic.For example: power plant need carry a large amount of coals in factory, needs outwards to carry the fly ash that lacks some slightly again.The scheme of present general belt conveyer is top set's fortune coal, uses the flute profile carrying roller, and inferior division fortune fly ash is also used the flute profile carrying roller.But the traffic capacity of flute profile carrying roller is less, often needs big bandwidth and higher belt speed.And belt speed one height, the fly ash airborne dust of inferior division is serious, contaminated environment.If top set uses the U-shaped carrying roller, can reduced bandwidth; Inferior division is used tubular carrying roller, can realize the sealing conveying, avoids airborne dust.The multi-form combination of this upper and lower branch carrying roller has produced belt conveyer of the present invention.
Specific embodiment:
The raw coal conveyer of certain power plant, long 8000 meters, require top set per hour in factory, to carry 2100 tons of coals, inferior division is per hour carried 850 tons in fly ash outside factory.Top set's load-transfer device is a U-shaped, chooses the parameter of bandwidth 1400mm, belt speed 4.0m/s.The inferior division load-transfer device is a tubulose, outside diameter 384mm.
The above; Be merely the preferable specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
