Definitions
- the bulk goods can be drawn off without any trough formation.
- the bulk material drops evenly across the entire cross-section. This also applies in particular to the bulk material from the edge regions, since a free slope angle can form below the hollow sliding bodies which are open at the bottom and which favors the flow of the bulk material in the outer region, so that there is no compression as a result of pressure build-up .
- Uniformity of the flow behavior in the entire cross-sectional area prevents blockages of the outlet openings by bridging as well as caking on the bunker walls and the formation of dead zones.
- the uniformity of the flow behavior can be further improved by introducing gas as a fluidizing agent into the cavities open at the bottom.
- the fluidization effect reduces the internal friction of the bulk particles.
- the flow behavior is equalized both in the case of cylindrical bulk material containers with conical discharge funnels and internals, and also in the case of bulk material containers with rectangular or square cross sections.
- the impairments which usually occur in rectangular or square containers in the region of the edge angles of the funnel walls and which can lead to flow delays or even to dead zones are not observed in the configuration according to the invention.
- the sliding body in the case of bulk goods containers with a cross-flow can be configured on the gas outlet side without an outer side wall, in order to take account of the changed bulk material behavior compared to a bulk goods container through which flow passes.
- FIG. 6 shows in cross-sectional representation an outlet funnel of a bulk goods container with a rectangular cross-section;
- FIG. 1 shows a diagram to show the dependencies of the heights of the side walls on the angle of inclination;
- 9 and 10 a modified embodiment of a square bulk goods container in a longitudinally sectioned illustration and in a top view.
- FIGS. 1 and 2 show a bulk container 1 according to the invention of an ionic configuration, to which an outlet funnel 2 in a conical configuration connects.
- a distributor cone 3 designed as a double cone, to which a conical sliding body 4 is assigned, which concentrically surrounds the centrally arranged distributor cone 3 and is connected to the sliding body 4 and the outlet funnel 2 via holding elements (not shown here).
- the walls 8, 9 and 12 and also the boundary walls of the distributor cone 3 are parallel to the wall of the outlet funnel. ters 2 aligned and thus have an equally large angle of inclination 6.
- the bulk material is withdrawn from the bulk material container 1 via a bulk material outlet 5, an unimpeded flow of bulk material occurring in the entire free cross-sectional area, as represented by the flow arrows 11.
- An embankment 10 with an embankment angle 7 is formed on the open side of the sliding body 4. Surprisingly, it is generally sufficient for the sliding body 4 to be open at the bottom in order to achieve a uniform removal of the bulk material from the bulk material container 1.
- FIGS. 3 and 4 show a bulk goods container 1 with a square cross section.
- the outlet funnel 2 is assigned a gas line 13 which is guided around it.
- holders 14 are provided in the center, to which branch lines of the gas line 13 are attached, which connect to the sliding body 4.
- the gas emerging in the area of the slope 10 and identified by arrows has the effect of improving the fluidization of the bulk material.
- the sliding body 4 also has a square cross-sectional shape with four outer side walls 8 and four inner side walls 9, which are connected via four end walls 12, in accordance with the geometry of the square outlet funnel 2.
- the outer side walls 8 are shorter than the inner side walls 9.
- a corner wall 8c (FIG. 4) can be provided in each of the corner areas, each connecting two adjacent side walls 8 and being shorter as this. In this way, the fact is taken into account that, for geometrical reasons, there is a flatter angle of inclination 6 (FIG. 1) in the corner areas than in the wall area
- FIG. 5 shows a bulk goods container 1 through which a gas flows transversely.
- the lateral gas spaces 16 and 17 on the gas inlet and gas outlet side are separated from the bulk material by blinds 15.
- An embankment 10 is formed between the blinds 15.
- the changed gas flow conditions are optimally taken into account in a bulk container 1 through which there is a flow.
- the outer side wall 8 In order to determine the optimum length of the outer side wall 8 on the gas inlet side of the container 1 for a specific bulk material, it may be advisable to design the outer side wall 8 as an outer sliding wall 8b.
- the design as a sliding wall 8b is, however, not only limited to bulk goods container 1 through which air flows transversely, but is also suitable as a control element for bulk goods containers 1 in which the gas is guided from bottom to top (for example according to FIG. 3). .
- FIG. 6 shows a top view of an outlet funnel 2 of a bulk goods container 1 with a rectangular cross-section, in which the transverse walls of the sliding body 4 are 8, 9 and 12 and the longitudinal walls are designated 8a, 9a and 12a.
- the outer side wall 8 " transverse wall
- the outer side wall 8a longitudinal wall
- a corner wall 8c is provided, which in turn is shorter than the side wall 8.
- FIG. 8 shows a sliding body 4 for a bulk goods container 1 with a rectangular cross section in a clear spatial representation. It contains the identification of the heights of the outer side walls, namely the height A of the outer side wall 8a, the height A 1 of the outer side wall 8 and the height B of the corner wall 8c.
- the distributor cone 3 is expanded to a roof-shaped distributor cross 18 which is open at the bottom and which is connected to the sliding body 4 and connects to gas inlets 19 in the outlet funnel 2.
- the area is expanded through which the gas, as indicated by flow arrows 21, can be introduced into the bulk material 22 in order to loosen it up and improve its flow properties.
- the slope 20, which is formed below the entire distributor cross 18 (FIG. 9), is added to the slope 10 below the sliding body 4.
- the total height was around 40 cm, of which the funnel height was 13 cm.
- the length of the container was around 18 cm and the width was around 12.5 cm.
- the outer side wall 8a had an inclination angle of 21.5 and was around 6 cm high.
- the outer side wall 8 had an angle of inclination of 30 ° and was approximately 4 cm high and the corner wall 8c had an angle of inclination of 35 ° and was approximately 2.5 cm high.
