摘 要 DG500型圆管带式输送机是一种新型的辅助运输设备。该型主要应用于 ABSTRACT DG500 pipe belt conveyor is a novel type of auxiliary transport equipment. It is designed to transport flour between the two workshops. Besides, it can be used to transport the clean and fast continuous short-range particles items. DG500 pipe belt conveyor mainly composed of electric drum, couplings, bend pulley, belt, roller, frame, tensioning device, cleaning device and feed system components. The bearing segment and return segment of this type of conveyor is complete closed transport. This characteristics can prevent transportation of materials from external debris. Meanwhile, it can prevent materials from rain and sun. So, in principle, this type of conveyor can avoid leakage, spilled materials, etc, and can meet the environmental requirements. DG500-type pipe belt conveyor transportation volume is large, and can finish the transportation volume of 100t / h, and through replace the rack, it can be used to tilted, vertical, turning transport which is the common mode of transport can not complete. This type of conveyor has the feature of compact in frame, approximately symmetrical arrangement of structure; transmission distance is short, easy movement; smooth running, safe and reliable, and easy installation.
