Definitions

• the invention relates to a device for loading a silo vehicle or the like with flowable bulk material.
• Loading devices of this type are used for the dust-free, vertical filling of dusty and semolina-shaped bulk materials such as cement, lime, gypsum, ready-made plaster, basalt, granules and the like, in some cases highly abrasive bulk materials, in silo vehicles, rail wagons or in other containers ⁇ turns.
• the dust-air mixture displaced in the silo vehicle by filling it with solids is sucked off through the exhaust duct in the loading device.
• a first type of loading device has an inner hose which forms the actual loading hose and which is concentrically surrounded by an outer hose. Both hoses can be pulled together or pulled apart like an accordion. The area between the inner hose and the outer hose serves to discharge the dust-air mixture that is to be filled during the loading process. the container is displaced. The lower end of this double hose loading device can be closed when not in use by a closure part which can be placed on the underside of the loading device in a dust-tight manner from below.
• Raising and lowering. of the closure part takes place via a cable system that connects between the outer and the inner hose
• loading device in which the “loading hose” consists of several wear-resistant, distributed over the drop height, each tapering downwards in the longitudinal direction of the Fal 1 shaft
• the known funnels have the shape of a hollow truncated cone with circular bases.
• the upper funnel sits with its lower end more or less far within the upper area of the lower hopper, which results in a different overall height of the loading device.
• the inner diameter of the funnels is chosen to be as large as possible.
• a funnel shape has resulted in all the funnels on the market in which the upper opening edge in each case has a larger diameter than that of a lower opening edge of the mounting cone to be closed by a sealing part 1.
• the invention has the object of providing a device for loading a silo vehicle or similar with pourable '• specify enabled bulk material, the ußvorrich- with a Verschl is equipped and does not have the disadvantages described above and thus allows the highest possible pouring rate.
• a device for loading a silo vehicle or the like with free-flowing bulk goods which has a hopper for the bulk goods, which has a plurality of funnels which are arranged distributed over the drop height and taper downwards in the longitudinal direction of the drop shaft an outlet duct outside of the Fal 1 shaft to discharge the at .
• the invention is characterized in such a loading device in that at least the lowest funnel is approximately rectangular in its cross-sectional planes normal to the longitudinal direction of the Fal 1 shaft, and that at least one funnel side in each of these cross-sectional planes is smaller than the smallest clear one Diameter of the cross-sectionally shaped Aufsetz ⁇ cone and that the first tension member is present along a straight line in the extraction channel, wherein it is fastened to the closure part in such a way that it can be guided in the free space between the placement cone and the bottom funnel.
• At least one funnel side thus cuts tendon-like in plan through the circular arc of the mounting cone which delimits the opening of the loading device.
• the pulling device therefore does not need to be exposed within the Fal 1 shaft and therefore not to the bulk material flow. This has positive effects on the lifespan of the pulling device and also on the functionality of the closure part.
• the hopper system which is particularly suitable for abrasive bulk materials can also be used in the loading device according to the invention.
• the loading capacity is also optimal, since there is no pulling rope or the like restricting the cross-section and slowing down the falling speed of the bulk material in the chute.
• the possibility with the loading device according to the invention to move the pulling device for the closure part to the outside of the funnel has led to an increase in the loading capacity compared to comparable Trichter loaders of approximately 10%.
• a guide is provided on the outside of the bottom funnel in which the pulling device for the closure part can be adjusted in height so that the Locking part can be positioned so that it can be tilted and twisted in different distances from the lower edge of the mounting cone.
• the tension member present for holding the closure part has two rigid parts in its lower region rod-shaped members and in its adjoining upper region two traction cables, one traction cable each being fastened to a rod-shaped member and each of the rod-shaped members to the closure part. Furthermore, each traction cable is held with its upper end in the upper region of the device so that it can be held and unwound so that the closure part can be held at different heights.
• the funnels are held together by at least one second tension member.
• This second tension member is fastened on two opposite side walls of each funnel, there being a guide on each of the two remaining side walls of each funnel in which the tension member required to hold the closure part is held adjustable in height.
• the funnels are thus held on the one hand downwards in the vertical direction by means of the closure part via the tension member holding the latter and also and independently thereof via the second tension members, on which the funnels are connected one above the other. Even if one of these two tension members fails, the funnel is prevented from falling down in an uncontrolled manner.
• a particularly advantageous development of the invention is characterized in that the chute is formed overall from such funnels.
