气体支承胶带是一种不使用槽式托辊,将胶带浮运在一层气膜上的散装带式输送机。这种理论是十年前荷兰通过一系列实验室和现场试验研究出来的。目前,这种带式机在欧洲已安装了150多台,在美国和加拿大也安装了50多台,用来运输从烟叶到碎石等各种各样的物料。除了支撑负载胶带的方式外,从各方面来说,气体支承带式输送机的功能与槽式托辊机的功能相同。该设备具有通常的机头、机尾、驱动电机、回带托辊及胶带。但它不象普通带式输送机那样每隔3～5英尺,就有一排槽式托辊。它的胶带是运行在一个成半园形的金属槽中。用一台小型离心鼓风机,将气体压进金属
Gas Support Tape is a bulk belt conveyor that floats tape on a film of gas without the use of a grooved roller. This theory was developed ten years ago by the Netherlands through a series of laboratory and field experiments. Currently, more than 150 of these belt machines have been installed in Europe and over 50 in the United States and Canada to transport a wide range of materials, from tobacco leaves to gravel. In addition to the means of supporting the load tape, the function of the gas-carrying belt conveyor is the same as that of the grooved roller machine in every respect. The device has the usual head, tail, drive motor, return roller and tape. However, unlike conventional belt conveyors, there are rows of grooved rollers every 3 to 5 feet. Its tape runs in a semi-circular metal groove. Use a small centrifugal blower to press the gas into the metal
