Description

The invention relates to the construction, in particular to facilities for the storage of bulk materials.

A silo-type structure is known, including external and internal containers. This structure has a large diameter and height, its spatial rigidity is provided by the device of internal tanks or partitions £ 1].

However, a large volume of the central container causes an increased pressure of the grain mass · on the walls and pulsation during unloading.

The technical solution closest to the invention is a silo for storing bulk materials of a polygonal shape in plan, including central and peripheral containers separated by radial partitions ^ 2].

A disadvantage of the known solution is that under the influence of horizontal seismic forces, peripheral capacities having a trapezoidal plan are subject to a change in the configuration of both individual capacities and the design in the chain. In addition, in the peripheral containers, all the outer walls border the external environment, which leads to the effect of atmospheric moisture on the grain.

The chain of invention is an increase in the spatial rigidity of a structure due to the effect of seismic loads and an increase in the tightness of peripheral containers.

The stump is achieved by the fact that in a silo for storage of bulk materials of a polygonal shape in plan, including the central and peripheral containers located along its perimeter, the latter are made triangular in plan and rigidly interconnected by the vertices of the triangles.

The drawing shows a silo in plan.

The silo consists of a central tank 1 and peripheral tanks 2, which are made triangular in plan and formed by panels 3, rigidly connected to nodes 4 along the entire height of the silo, have bypass holes 5 to eliminate grain pulsation during discharge.

The proposed device operates as follows.

In a loaded state, under the influence of the pressure of the grain mass located in the central container 1, the load is perceived by the vertical panels 3 and nodes 4 forming the peripheral containers.

Under the influence of horizontal seismic forces, peripheral capacities having a triangular shape in plan are less susceptible to configuration changes and form a more rigid system compared to known solutions. The redistribution of loads on all pa-, non-silo and container nodes in a triangular pattern contributes to the uniform load of the elements of the entire silo structure. Most of the grain mass located in the central and peripheral containers is isolated from atmospheric influences, since increased humidity disrupts the microbiological process, increases the physiological activity of the grain mass, which causes vertical wall or nesting self-heating. The temperature difference leads to fluctuations in the thermal balance, the violation of the thermodynamic equilibrium of the grain mass, vapor condensation, mass loss, deterioration in quality, S resulting in a significant increase in grain toxicity. The insignificant area of the silo enclosing wall in contact with the external environment requires much less active ventilation, drying, and control of the grain mass. The number of peripheral silos can be different, depending on a given total capacity. The walls of peripheral silos reduce the design spans of super silo ceilings,.

foundations and bottoms, thereby achieving material savings.

in plan and formed by panels 3, rigidly connected in nodes 4 along the entire height of the silo, have bypass holes 5 for eliminating grain pulsation at the inlet. The proposed device works as follows: In the loaded state under the pressure of the grain mass The central container 1, the load is taken up by the vertical panels 3 by the nodes 4 forming the peripheral tanks. Under the influence of horizontal seismic forces, peripheral vessels having a triangular shape in plan are less susceptible to changing configurations and form a more rigid system compared to known solutions. Redistribution of loads on all pa-. The vessels and the nodes of the containers in a triangular pattern contribute to the uniform workload of the elements of the 5-s silo design. Most of the grain mass, located in the central and peripheral vessels, is isolated from atmospheric influences, since the increased humidity disrupts the microbiological process, increases the physiological activity of the grain mass, which causes vertical wall or anemia self-heating. The temperature difference leads to fluctuations in the heat balance, disturbance of the thermodynamic equilibrium of the grain mass, vapor condensation, loss in mass, deterioration of qualities. As a result, the toxicity of the grain increases significantly. The insignificant area of the silo fencing wall in contact with the external environment requires much less active ventilation, drying and control of the grain mass. The number of peripheral silos may be different, depending on the given total capacity. The walls of the peripheral silos reduce the design spans of oversize ceilings, foundations and bottoms, thereby saving material. The invention The silo for storing bulk materials in a polygonal shape in plan, including a central container and peripheral vessels located along its perimeter, is distinguished by the fact made of triangular shape in plan and rigidly interconnected vertices of triangles.
