The invention discloses a no-dust
air cushion conveyor and a modular groove
pipe prefabrication and installation method. The no-dust
air cushion conveyor is characterized by comprising a frame, a modular groove
pipe, a conveying
system, an air feeding device, a sealing box and a filter device. The modular groove
pipe is prefabricated as a standard module according to a certain specification length, so that the field installation and construction are simple and fast, and the manufacturing and installation cost is saved; and the no-dust
air cushion conveyor changes rolling friction supported bya general conveyor support roller to air
fluid friction, achieves the sliding performance of the support roller supporting and the operation stability and tightness of the pipe supporting, and is particularly suitable for
powder conveying. The no-dust air
cushion conveyor solves the problems of high operation resistance of a conveying belt, easy
material scattering, generation of flying dust, environmental
pollution and influence on the material purity by invasion of external pollutants in a
belt conveyor in the prior art, and solves the problem of material
pollution due to easy wear and degumming of the edge of the conveying belt of the tubular
belt conveyor.
