The present invention relates to a ventilating and blanking device for a coal storage Eurosilo. The ventilating and blanking device includes a top blanking pipe, an axial flow fan and a baffle door, the top blanking pipe including a first pipeline and a second pipeline, an air supply pipe is connected to a side wall of the second pipeline, and the baffle door is connected to a driving mechanism; during blanking, the driving mechanism drives the baffle door so as to make the baffle door close the air supply pipe and the axial flow fan is shut off; and during ventilation, the driving mechanism drives the baffle door so as to make the baffle door close the first pipeline, and the axial flow fan is turned on. Compared with the prior art, the present invention has the advantages of ventilation efficiency, good ventilation effect, etc.

The aspects herein relate to the field of fall prevention systems, and more specifically to fall arrest systems for storage bins and more particularly to grain bins or silos. In one aspect, a fall prevention system for a ladder may have an anchor plate coupled to a roof. In another aspect, the fall prevention system for the ladder may have an anchor bar coupled to at least a portion of the ladder. A rope is coupled at one end to the anchor plate or bar and at the other end to at least one rung of the ladder using a fastener. A rope grab is slidably coupled to the rope between the anchor plate or bar and the fastener.

A collapsible storage system for flowable material, for example granular material, includes a base frame and an upper frame which is movable between a collapsed position and a working position spaced above the collapsed position. A plurality of storage silos are supported in a row, each including a hopper discharge cone on the base frame and a collapsible tubular wall assembly connected between the discharge cone and the upper frame. Redundant loading conveyors are provided in communication with the silos across the upper frame for loading and redundant unloading conveyors are provided in communication with the silos across the base frame.
