throw different distances.

There are furnace charging devices are known in which the coals by several Alternately working throwing shovels are thrown onto the grate and the individual throws be distributed over the length of the grate by the throwing distance of each shovel with each single litter is different from the previous and following litter, whereby the throwing distance is usually three-fold.

ίο On this type of loading device the present invention relates. It consists in the fact that the throwing blades Fill in the entire width of the grate without any gaps, only through the partitions dividing the coal feed shaft are separated and all cast at the same time, each with a different throw.

The aim of this is to ensure uniformity and to counteract the formation of smoke as much as possible Loading can be achieved better than with the older devices.

Another feature of the invention is the special type of fuel supply in front of every throwing shovel. When the coals are pushed together to all three shovels, each one is brought above Shovel an intermediate container, the emptying opening of the associated Bucket is controlled out. In this way, the containers fill up with the evenly closed one Coal to open individually at the appropriate moment and the coal in front of the one ready to act Dropping shovel;

In a version with three throwing blades, the new loading device is on the Drawing shown. Fig. 1 gives a longitudinal section with a subsequent boiler. Fig. 2 is a vertical cross-section along the line 2-2 of Fig. 1 seen in the direction of the arrow. Fig. 3 to 5 are special representations. Figure 6 is a loading scheme.

The coals in the hopper A are conveyed over the bridge B through the opening C onto the plate D , which is bent equiaxially to the pivot point of the throwing vanes and from which the fuel is thrown onto the grate E by means of the throwing vanes.

The three litter shovels a, b, c each sit on a special shaft. These waves are nested within each other. The inner shaft d carries the throwing blade α. A lug e (see also FIG. 5) is adjustably attached to one end of this shaft. This lug cooperates with the stops f, g, h , which are attached to a disk i . The disc * sits on the driven shaft k. The stops are designed as ring sectors coaxial with the center of the disk. Their distance from the center is different in such a way that the sector f is on the circumference of the disk, the sector g closer to the center dci disk and dei§ektocA. is even closer to the 'center of the disc'. The disc, t rotates .-! Rotates% ι * BfeilHM ^ h direction (Fig. 5).

Accordingly, blade α experiences a different degree of oscillation. During this oscillation, as can be seen from FIG. 1, the coiled spring / is tensioned. It is wound around a horizontally guided pole and lies at one end; to a disk attached to the rod η j and with its other end against the cabinet F. The rod is hinged to an upper ■ ίο extension ο of the shovel. The same setup is for the show; fine b and c hit. They sit on the j shafts d1 and d2, on which the lugs el \ and e2 are attached. These lugs work j with the stops f1, h1, g1, g2 and h2, f-! together that on both sides of the on the; Shaft k seated disk i1 (Fig. 2) are attached. The stops f, f1, f2, g, g1, g2 and h, h1, h2 are, as can be seen from FIGS. of the adjacent disk the corresponding stop (e.g. Z "1 against f or f- against f1) has moved back one place. e1 and e2 \ each with a stop for engagement, e.g. with the stops h, g1 and f'1. This causes the throwing vanes a, b, c to pivot backwards i; the vane α least, j the vane b a little more and the blade c the most. The different swiveling corresponds to a different tension ■ of the associated springs I, I1, / 2. As the disks i and il continue to rotate, the lugs e, e1, e2 leave the associated stops at the same instant. The three blades a, b, c deflect forward and convey the fuel located on the curved plate D onto the grate E. Since the deflection is different due to the different spring tension, a charging scheme according to FIG. 6 arises, from d em first comes into question the left field. The shovel α conveys the coal to the associated field α1, the shovel b to the field bl and the shovel c to the field c1. As the disks i and i1 continue to rotate, the lugs e, el, evon are raised anew and the springs I, I1, P are tensioned anew. But now the stops f, h1 and g2 work together with the lugs. This creates a loading scheme for which the middle field in FIG. 6 is suitable. The coals are conveyed voii.vdeh .Wurfschau'feln'a, b, c to the fields α% -φ? Ρ «* Ι.

During the forward oscillation of the throwing blades a, b, c, the fuel is now thrown onto the grate in the manner shown in the third field of FIG. b3, cs. When one revolution of the disks i, i1 has been completed, the whole grate has been charged. The game begins again. Of course, it does not matter in which sequence the individual throwing blades are operated, except for that successively covered fields should be as far apart as possible, but in any case not edge to edge. The flaps q are also hinged to the upper extensions 0, o1, o2 of the blades a, b, c by means of a linkage p. These flaps are used for closure of the intermediate container G, which is above each Wu rfschaufel is formed by the cabinet and the partition wall γ. The intermediate container is divided into three compartments by partitions s and t. One flap q each closes the emptying opening of the compartment belonging to the corresponding shovel a, b, c when the throwing shovel is flicked forward; they clear the emptying opening when the scoop recedes. In this way, the right amount of coal is fed to each shovel at the right time. The fuel is brought close to the throwing shovel in question with each stroke, since the closing flap, which also serves to guide the fuel, makes the same deflections as the corresponding throwing shovel. P α te ν τ claims: 1. Furnace feeder with throwing shovels, which are alternately different throw far, characterized in that the throwing blades fill the entire width of the grate without gaps, only through the the partition walls dividing the coal inlet shaft are separate and all at the same time each with a different throw distance. 2. furnace charging device according to claim 1, characterized in that no an intermediate container is attached above each throwing shovel, its emptying opening opened and closed by means of a flap hinged to the throwing shovel and controlled by it will.
