1.overview
Curve of the belt conveyor is a special equipment to solve these problems, is suitable for the bending of the underground coal mine roadway, transfer of open-pit mine, mining transport, port of shipment, the construction of hydropower station is conveying, metallurgy, chemical industry, building materials, hydropower plant raw material conveying, can be used. Chengdu air smelting materiel transportation engineering co., LTD is a professional company engaged in the material conveying, in cooperation with foreign enterprises, development, design, careful study, completed the theoretical calculation and practical application of belt conveyor curves of the validation. In the aspect of equipment manufacturing, improve the production link, supporting the domestic and foreign advanced equipment, to promote the domestic application. Preliminary results have been obtained.
2.、Equipment principle and advantages
Curve within the tape machine is the horizontal turning belt curve up (the reverse and highway, railway bend lateral raise) which is to turn roller level raise installed inside, at the same time combined with roller forward installed on both sides, make the conveyor runs produces an outward centrifugal force to overcome a centripetal force component caused by turning conveyor tension, to ensure the normal operation of the conveyor belt. This kind of conveyor can realize the natural turn of the conveyor belt and avoid the special structure special conveyor belt. The curve tape machine can be used to make the roadway along the terrain to the layout, and the horizontal turn and the vertical turning (the radius of the turn is smaller than 150 meters. On the same piece of tape, there can be five 300-meter turns. To avoid obstructions or unfavorable areas, achieve less or no intermediate transfer station, which has the following advantages:
1.It can realize large quantity and efficient transportation, which can meet the requirement of bulk cargo transportation.
2.Transportation costs can be greatly saved.
3.3d layout can be performed according to the terrain and actual needs.
4.The power supply and control of the system are more concentrated, thereby greatly reducing the investment in power supply and control system.
5.It eliminates the unloading height of the medium and avoids the damage of the object (such as coke) and reduces the energy consumption of the system.
6.Shorten delivery distance and reduce space.
7.Reduce the transfer point, improve the system security reliability.
