Totally-enclosed double-air cushion belt conveyor

Abstract

The invention provides a totally-enclosed double-air cushion belt conveyor. Air cushion gas distribution plates, gas cavities of the air cushion gas distribution plates and air cushion air supplying systems are arranged under a linear upper layer conveyor belt and a linear lower layer conveyor belt of the belt conveyor respectively. A feeding system and a discharging system of the belt conveyor are arranged above the lower layer conveyor belt, and the whole conveying system is placed into a shell of the conveying system. The lower air cushion gas distribution plates are designed to be plane or concave; and the conveyor belts are designed to be skirted. The totally-enclosed double-air cushion belt conveyor has the characteristics of large transport capacity and full enclosure, and is especially suitable for long-distance delivery of powdered materials. The lower layer conveyor belt is used for conveying materials, thus flying materials and materials adhered on the belt can finally drop down to the lower layer conveyor belt, and a cleaning system is not needed.

Description

technical field [0001] The invention relates to an air-cushion belt conveyor used for material transportation, in particular to a fully enclosed double-air-cushion belt conveyor. Background technique [0002] Material conveying is one of the important process links in all kinds of industrial production, and mechanical conveying is one of the main forms. Mechanical conveying specifically includes screw conveying, scraper conveying, vibrating conveying, belt conveying, etc. Among them, belt conveying Conveying mainly includes three types of equipment: roller belt conveyor, air cushion belt conveyor and tubular belt conveyor. Idler belt conveyors have a relatively long conveying distance and stable operation, but have the disadvantages of heavy equipment and high cost, and there is vibration during the movement of the conveyor belt, and the material accumulation only accounts for the middle part within 80% of the total width of the conveyor belt, and the efficiency is relativel...

AI Technical Summary

Problems solved by technology

Idler belt conveyors have relatively long conveying distance and stable operation, but have the disadvantages of heavy equipment and high cost, and there is vibration during the moving process of the conveyor belt, and the material accumulation only accounts for the middle part within 80% of the total width of the conveyor belt, and the efficiency is relatively low. Low, and for powder materials, there will be materials flying during the conveying process, which not only pollutes the environment, but also brings material loss; although the weight of the air cushion belt conveyor has been reduced and the cost has been relatively reduced, it is still There is a certain amount of vibration and there is no airtight problem. The flying problem of the powder material at the inlet and outlet and the return process of the conveyor belt is still serious; the tubular belt conveyor has the problems of heavy equipment and high cost.
