Definitions
- Another known device requires the placing of a box with rigid side walls and a rigid, perforated top wall, on the bottom of the container, in order to form a hopper about the discharging outlet.
- the top wall of the box is covered by a pervious material.
- the interior of such a box is connected to a pressure-air source so that when admitted into the box, the pressure-air flows through the perforated top wall and the pervious material and penetrates into the powdery or granular material in the container.
- the pressure-air thereby fluidizes the powdery or granular material, so that the material acquires a form enabling it to flow like a liquid downward to a collecting area adjacent to the discharging outlet at the bottom of the container.
- the instant invention provides a discharge device comprising a membrane member made of an easy flexible, pervious material, which is attached to the insides of the container. At the bottom of the container the material defines a space between the side walls and a zone adjacent to the discharge outlet of the container. This space is connectable with a source of air under pressure.
- the membrane member has fine air channels of such a width, that when the pressure-air is admitted into the defined space, it inflates the membrane member, Simultaneously, however, the pressure-air escapes through the fine air channels. This pressure-air is also used to fluidize the material to be discharged. In the inflated position, the surface of the membrane member smoothly inclines toward the zone adjacent to the discharging outlet of the container.
- the membrane member is constituted by the top wall of a pad, the side walls and bottom of which consist of impervious, air-proof material.
- the top wall is connected with the bottom of the pad at the zone adjacent to the discharge outlet of the container.
- the membrane member is made as a cover, the edges of which are attached to the bottom and insides of the container with an air-proof seal.
- the membrane member for use in a horizontal, cylindrical container is made as a cover with a generally V-shaped cross-section profile and inclines from the ends of the container towards the zone adjacent to the discharge outlet at the bottom of the container.

- Element 3 is a suction pipe, which extends into the cargo hold, and by means of which the cement is discharged from the cargo hold when the vessel is unloaded.
- the suction pipe 3 is located approximately at the center of the cargo hold and extends downwardly nearly to the bottom 2.

- the chambers radially extend from the central area to the side walls 5.
- FIGURE 2 shows the form of the pad during the discharge of cement bulk 16 from the cargo hold.
- Pressureair is admitted through the'hoses 7 into the deflated chamber 13, so that the top wall of the pad is raised and constitutes a surf-ace, which smoothly inclines downwards from the side walls 5 to the central area 9.
- the fine air channels in the pervious fabric material of the top wall 6 are of such a width, that the pressure-air simultaneously escapes through the fabric of the top wall, so that the air penetrates into the cement bulk 16 and, in effect, fluidizes the cement, causing it to rapidly flow downward over the inclined surface to the central area 9, where the cement is sucked into the pipe 3 for discharge.
- the pressure-air admitted into the chamber 13 of t-the pad also flows through the pervious gores 15 and is rapidly distributed to each section 14 of the pad.
- the tightness of the meshes i.e. the width of the fine air channels of the fabric of the top wall 6, should be selected according to the consistency of the actual powdery or granular bulk material.
- Gravel for example, r q ires m9? P essure-air than cement, in order to be fluidized, and thus flow rapidly downward to the discharge outlet suction pipe 3.
- FIGURE 4 shows a modified embodiment of the pad, in which the chamber 13 is divided into four cells, by means of partition walls 17 made of air-proof fabric.
- the top wall of each cell is supported by gores 15 of pervious fabric. This construction makes it possible to distribute the pressure-air only to the one or to the other side of the pad in order to trim the vessel during the loading and unloading operations.
- FIGURES 5-7 show a further embodiment of the pad, in which the discharge outlet 3 is located at one side of the pad.
- the pad is divided into cells by means of airproof partition walls 17 extending radially from a semicircular collection area 19.
- the top surfaces of the cells are supported by gores 15 of pervious synthetic resin fabric.
- FIGURE 8 shows an alternative means for attaching the pad to the side walls 1 of the cargo hold.
- the pad is provided with surrounding flaps 20 of flexible synthetic resin fabric.
- Anchoring steel profiles 21 with a longitudinal, dovetail-shaped channel 22 are attached to side walls 1 and bottom 2.
- the pad is attached to the steel profiles 21 by pressing the flaps 20 into the channels 22 and holding them securely in place by means of short securing flat bars 23, so that the flaps are wedged tight between the steel profiles 21 and the flat bars 23.
- FIGURE 9 shows an alternative embodiment of the pad, wherein it is provided with a surrounding air channel comprising a separate hose 24 of pervious synthetic resin fabric having a triangular cross-section and fastened to the edge of the top wall 6.
- the hose or channel 24 is provided with an pressure-air inlet hose 18.
- FIGURES 10 and 11 show an alternative embodiment, in which the pad is provided with a surrounding air channel 25, which is formed by a top wall 26 of pervious synthetic resin fabric, the air-proof bottom 4 and side walls 5 of the pad and inner Walls 27 of air-proof synthetic resin fabric, which separate the channel 25 from the chamber 13 of the pad.
- the channel 25 is provided with a short hose 28 projecting through a recess in the side wall 1 of the cargo hold and is adapted to be connected with a hose (not shown) from the pressure-air source.
