ABSTRACT:
A compact vacuum conveyor apparatus for the pneumatic conveyance of loose bulk materials includes a separator, a delivery device, a vacuum pump aggregate and the necessary appurtenances which are operationally assembled and contained in a support cabinet of rectangular parallelepipedal shape and of about the size of a large shipping container which can be loaded onto a truck. A hollow tubular conveyor extends from and is supported on the front wall of the cabinet and is connected to the separator. A crane structure supports the conveyor and is likewise mounted on the front wall of the cabinet, a compression chord of the crane being supported on bearing lugs along the cabinet front wall, and being upwardly and downwardly pivotable about a horizontal axis of rotation by means of hydraulic piston and cylinder units extending between a tension chord of the crane and the roof of the cabinet. The tubular conveyor includes a telescoping tube arrangement as a horizontal segment, and has a vertical segment including a flexible intermediate member. The horizontal segment may be adjusted to the desired length by a tugging device. When loaded onto a vehicle, the apparatus may be used as a mobile installation, or may be deposited at the site as a stationary installation or, when coupled with a slewing gear arrangement, may form a slewing installation.
