Description

one

The invention relates to the construction of elevators and can be used in silos for storing grain and other bulk materials.

The closest technical solution to the proposed is storage for bulk materials, including a system of interconnected separate cylindrical containers, loading and unloading galleries 1.

However, the known storage does not allow simultaneous storage of various types of bulk. In addition, with the release of granular in the central container, dynamic processes arise that lead to the need to take them into account and, consequently, to an increase in the material intensity of the structures.

The purpose of the invention is to provide storage for various bulk materials, to eliminate dynamic processes during their production and to increase the volume of stored material.

The goal is achieved by the fact that in the storage for bulk materials, including a system of interconnected individual cylindrical containers, loading and unloading galleries, each of the cylindrical eivacocTeft in conjunction with the neighboring is equipped with vertical cavities, symmetrically about its axis, greedy In the walls of the containers communicating with the cavity, openings are made.

FIG. i shows the vault,

0 where the individual containers-banks are located along a closed trajectory and form an internal large eaten state in a monolithic variant, a plan; Fig. 2 is the same, with the ordinal arrangement of cans in a monolithic variant; in fig. 3 is a fragment of the interface of the main containers with the additional containers in the lunoliths variant; on .fig. 4 - storages; in fig. 5 - location of volumetric elements along the arc of a circle, assembly option; in fig. b - interface of two bulk elements, modular version; in fig. 7 is a variant of the construction of bulk elements for silos with their regular arrangement, a composite version.

Stored in a monolithic version, it consists of jars arranged along a closed path, for example

measures 1-9, formed by the imr of the central container 10 h additional external 11 and internal 12 tanks (figure 1). With the jar arrangement of the cans (р), both additional containers 11 are external, although an alternative is possible when these additional containers are performed on one side.

Each additional container is formed by the walls of the mating cans, for example 1 and 2 (Fig. 3), their joint element 13 and the vertical rectilinear walls 14 and 15 connecting the mating cans. Each additional container is connected through a system of overflow openings 16 located at a height from at least one of the adjacent cans and through openings 17 when the banks are located along a closed trajectory with a central container 10. The containers 11 and 12 are provided with openings 18 for the release of bulk. If necessary, additional banks are made with curved (e.g., along a circular arc) vertical walls. In the latter case, the capacity of the external containers 11 increases, and for the internal containers 12, the carrying capacity of the walls 19 increases (construction improves) due to the pressure of the bulk in the central container 10.

The storage has loading and unloading galleries (not shown on the drawings). Each of the main cans (at their regular arrangement) with the release of bulk, which is the most important operation during the operation of the facility, only works on the effect of static bulk pressure in them, and the dynamic pressure that occurs only in additional containers 11-12 slightly. Its value should be taken into account only when calculating the walls of 14 or 19 external tanks 11

When the cans are located along a closed path, their walls experience static pressure from the bulk in the jars themselves and the bulk in the tank 10. Here, dynamic processes are inherent only in additional capacitances 11 and 12, which, although insignificant, must be taken into account when calculating their walls.

For the implementation of the prefab storage option, three-dimensional elements (Figs. 5-7), consisting of a ring 20 with at least one butt element 21 combined with it, are used. In the areas of conjugation of the rings with a butt element, at least one the vertical cavity 22 adjoins them, communicating with the internal cavity 23 of the ring through the holes 24 in its

wall. In the body of the volume element there are vertical and, horizontal channels 25 and 26, which serve to accommodate, respectively, the vertical force, tension ring 20, reinforcement 27 and horizontal elements 28, which surround the volume elements.

The discharging of bulk silos is discharged through openings 29 in the bottom of vertical cavities 22.

The outer surface of the walls 30 of the vertical cavities 22 is located in the same plane with the surface 31 of the butt elements 21, along which the adjacent volumetric elements are joined.

The dimple keys 32 are made on the surface of the butt elements. They serve to strengthen the joining of adjacent elements using, for example, concrete 33.

In the variant shown in FIG. 7, each inner ring has four butt elements aligned with it, and the corner and side elements, respectively, two and three. At the same time, internal sprocket-stars 34 are formed between the contiguous ring banks, the discharge of which is carried out through one or several outlet openings 29 in cavities 22, from which they communicate through openings 35. The number of interconnecting capacities 22, 23 and 34 depends on the number of types of loose.

Tension of horizontal force elements 28 should be performed after a layer of concrete 33 (on a fine aggregate) or cement mortar (preferably on expanding cement) gains RQ strength, but not less than 80% of the design mark.

Similarly, the tension of the vertical force elements 27 is produced when the rings are installed at the height of the cans, after which cement mortar is injected into all the channels with power fittings to protect it from corrosion.

After tensioning the entire power armature. The structure of the erected cans of the proposed elements has sufficient rigidity, strength and durability.

In the embodiment of the construction of Fig. 1, one (different) type of bulk material can be stored in each of the cans and the central container, since each of these main containers is made in communication with only one additional container with its own outlet.

Since the device additional tanks 11 and 12 for monolithic and 22 for precast options leads to the elimination of dynamic processes

in banks, this leads to a decrease in the consumption of materials for their construction. The device of additional tanks significantly increases the rigidity and, consequently, the strength of the entire structure.

In addition, with this design of the storage, its operation is simplified. The great advantage of the proposed design is that it provides simultaneous storage and processing of various types of bulk and is a repository of a universal type.
