(54) BUNKER FOR STORAGE AND DOSED DELIVERING OF BULK MATERIALS

12

The invention relates to the storage and distribution of bulk materials and can be used dp dosage of weakly flowing materials.

on the main auth. St. W 59вв22 is a known hopper for storing and metering out bulk materials, containing a cylindrical body and a rotating bottom in the form of a disk with a radial discharge slot, the outer edge of which is located under the lower edge of the body, and the inner edge passes through the center of the disk, while at least one fixed plate 1.

A disadvantage of the known hopper is that the disk rotates with respect to the cylindrical body, therefore it is necessary to observe the required gap between the / lower edge of the cylinder and the surface of the disk. When the disk is rotated, if fine-grained materials are unloaded, its particles pass through the gap and are poured from the disk, which causes material loss.

The aim of the invention is to provide sealing of the hopper.

The goal is achieved by the fact that a sealing means is placed between the hopper body and the rotating disk.

In this case, the sealing means consists of upper and lower rings, rigidly fixed respectively on the above-mentioned body and disk, and an extrusion element,

10 located between these rings.

Figure 1 shows the proposed bunker, front view; figure 2 is the same, top view.

The hopper contains a cylindrical

15 housing 1 and the bottom in the form of a disk 2 with a radial discharge gap 3. disk 2 rests on guide rollers 4. Backlash 5 between the lower edge of the housing 1 and disk 2 seals et 20 with an annular projection 6 fixed to disk 2. Protrusion 6 interconnected with the seal to the cimma material 7, inserted into the annular socket 8, fixed in the lower part of the outer surface of the housing 1 / cylinder. The outer edge 9 of the slit 3 is located under the lower edge of the housing 1, and the inner edge 10 passes through the center of the disk 2. Under the disk 2 30 there is a conical chute 11.

The rollers 4 are rotatably secured to the brackets 12, which in turn are rigidly connected to the housing 1 and to the conical chute 11 A fixed vertical plate 13 is attached to the housing 1. The disk 2 is brought into gear from the toothed drive gear 14.

When the disk 2 rotates, the discharge gap 3 moves and the material is evenly poured into the chute 11. Due to the indicated location of the gap 3, the latter, during its movement, covers the entire area of the circle under the housing 1, thereby preventing the formation of stagnant zones of the material. In this case, the rotating annular protrusion 6, interconnected with the sealing material 7, prevents the loose material from falling through the gap 5. The plate 13 keeps the lower layers of the material from rotating together with the disk 2.

In rafts, the mechanism increases the feasibility of using the known bunker for fine-grained bonded materials, which is even more

increases its economic effect by eliminating significant material losses under load.
