The furnace concerns a round silo container with an upper material ; feed device and at least one discharge opening; in the silo floor, consisting of an upright, both ends open cylinder jacket, which / rotatably supported and means at its periphery engaging drive members in rotation the cylinder axis can be displaced, the inner one from the cylinder jacket in the radial direction to a central pivot bearing running struts to accommodate radial and perpendicular we- * kenden forces and serve for centering.

It is known, round silo, which in the above are designed to be used when it comes to using simple means to ensure that the Can be well distributed evenly over the container cross-section and can also be discharged evenly. if however, with the lowest possible overall height, the largest possible Fit is to be achieved, then result at the known round silo containers of the type in question hereditary problems.

The well-known round silo containers either have one firmly connected to the cylinder jacket or rotatable by itself

supported soil. The central pivot bearing, rait -which the radial forces are derived, is therefore arranged under the floors of these silos. That means at least for them Accommodation of the central pivot bearing overall height is lost, which is not used to increase the receiving volume can be. If an overhaul or repair is required on the central pivot bearing of these known round silo containers, then there are usually considerable difficulties because these bearings are not accessible, at least when the container is full are. To implement central pivot bearings that can be serviced, additional complex measures, in particular Increases in construction heights must be accepted.

The price increase is based on the task of a round silo container of the type mentioned in such a way that it has the lowest possible overall height with a large capacity and has a serviceable central pivot bearing with a simple structure.

In order to solve the above-mentioned problem, the is indicated in the introduction said round silo container according to the innovation in that the silo base is fixed with respect to the cylinder jacket and that the central pivot bearing from one of the upper face of the cylinder jacket to the silo bottom reaching, with the cylinder jacket circumferential maintenance shaft is covered.

In contrast to the previously known silo containers, the new container has a solid silo bottom. As a result, the cylinder

"This measure only makes sense when the fixed silo floor is used. The overall height of the container can thus be reduced by all the proportions previously required to accommodate the central pivot bearing the central pivot bearing protects against the garbage and at the same time enables constant maintenance of the pivot bearing. -'- Y-

It has proven to be advantageous if the struts which transmit the radial forces to the central bearing are at the same time designed as scraping plates projecting upwards from the silo floor over a noticeable height or are provided with such plates. In a typical application example there are six; those arranged at even circumferential intervals © struts with scraper blades provided ^ /; ; _; . :

Advantageously, several, e.g. three, reciprocating piston engines arranged at equal angular intervals are also included synchronous operation provided. The arrangement can be in one practical example be provided so that the container itself turns completely about 2 1/2 times in 24 hours. Around blind spots to avoid and at the same time allow maintenance of the central bearing, the central pivot bearing can advantageously from one of the upper face of the sheet metal jacket to Maintenance shaft extending around the silo floor and surrounding the sheet metal jacket be covered.

The inflation is explained in more detail below with reference to the schematic drawings of an exemplary embodiment. /]

fig. 1 shows the new round silo container, which is also more advantageous- * wise as a transportable or prefabricated container can be designed, in Seitenanssehen, namely in .der right half in vertical section, while Figure 2 is a top plan view of the container. ,

The jacket 5, composed of individual shots of sheet metal, of the container 1 is on its top 7 ^ and ^ its Onterseite 8 open. The upper part can be formed by a sloping edge area β somewhat narrowed to prevent the good from falling out to be avoided in the case of strong enamel. The goods can be arranged in the circular container by one above the container Screw conveyor 3 with discharge openings, 26 are covered.

The lower end of the silo container 1 is covered by a fixed silo floor 2, e.g. a concrete ceiling of a Building. In the silo bottom 2 discharge openings are in Sorm of Breakthroughs 9 arranged. Maintenance of the discharge openings; Discharge conveyors 4 are provided in IOrm from Schneeken conveyors. , -; ';. "

The sheet metal jacket 5 is reinforced in its lower area by belt-shaped stiffeners 10,11, which are made of profile iron in Can exist in a ring shape. In the example shown, two T-shaped iron belts are provided. These are solid with the lead jacket connected and are at a mutual distance as well as in Distance from the floor 2. In the example shown, the two stiffeners 10 and 11 are on the outside of the sheet metal jacket arranged. With the stiffeners 10 and 11 act Pührungs-. roll together, which on supports distributed in the longitudinal direction 12 or 15 and 14 are provided, the rollers on the underside the lower reinforcement 10 or the upper side of the Aus; stiffener 11 rest. Since the round silo container with the accompanying ropes can be designed relatively easily, it is sufficient to him with the help of the rolling devices mentioned to a few in the circumferential direction to support distributed places. In the example shown, there are six such support units 12 in the circumferential direction arranged distributed. This possibility exists because; by, the roles are only part of the; G-weight added to needs and a substantial part of the weight of the Good is caught by the silo floor itself.

The other salvation of the vertical weight or the vertical ^ Forces is absorbed by a central roller bearing 16, whose rollers are arranged so that they can absorb not only the vertical, but also the radial forces. Of the The raceway of the central roller bearing is made by radial struts 15 firmly connected to the belt-shaped reinforcement 10 or 11, which struts 15 evenly transmit the radial forces to the raceway. Because the silo container due to its rotation is always evenly loaded and the speed of movement is only small, only small unbalanced radial forces occur so that there is a very simple stable "arrangement.

In order to avoid dead spaces above the central roller bearing and at the same time a slight monitoring of the central one To enable roller bearing, this is done by using the entire height of the jacket 5 reaching shaft 17 covered by the maintenance person to the warehouse

The drive of the round siio container takes place with the help of a kind Ratchet drive, for what purpose the belt-shaped stiffening 11 is occupied on its outside with drivers 18, with which the tappets of piston engines 19 interact. In the example shown, there are three such thrust piston engines 19 evenly distributed in the circumferential direction, two of these Piston engines only by arrows 19a and 19b are reproduced. The reciprocating piston engines can be derived from the same are driven in such a way that they are simultaneously

work at the same time _? However, the arrangement can also be such that "in the case of a plurality of So-stroke basket motors, the mode of operation overlaps, so that an essentially uniform rotary movement is achieved. However, since the speed is extremely low, preferably only a few revolutions per 24 hours intermittent movement of the silo container is irrelevant.

The aim is that the filling material rotates evenly with the container. Only when this is achieved can a completely uniform filling or emptying be guaranteed under all circumstances. In order to let the filler take part in the rotation: inevitably, the struts are. 15 advantageous "advantageously provided with scraper plates 25, which, for example, in a practical application example, protrude up to a height of about 1 1/2 m from the silo bottom 2 and are provided with corresponding scraping edges> which strip tightly over the silo bottom and may also be provided with elastic flaps or tongues in order to sweep the silo floor empty when the silo is completely emptied is forcibly driven at least in untereriBereich, it moves with check at almost empty vessel, while 'at very full container, the opposite in the upper ^regions; Good by rotating walls or the inevitably entrained ■

The lower layer of the goods is moved along with it. It can be seen that the infeed conveyor has two discharge openings 26 which are arranged in such a way that they load under the former radial areas of the container uniform loading is further promoted. ^: ,
