Description

Known collapsible reinforced concrete semi-bunker warehouses for cement, made with. underground gallery tent forms, with lateral gravitational chutes located in the inclined walls of the tent. In these warehouses, there is no means of loosening the packed cement, which is why it is impossible to unload all the cement gravitationally and some of it is unloaded only after manual collapse from the inside. In addition, it is necessary to arrange the internal longitudinal embankment, on which the foundations of the middle support columns of the warehouse tent are installed, which reduces the capacity of the warehouse and reduces its precast,

The purpose of the invention is to increase the capacity of warehouses, to ensure, during unloading, the movement of material through air enrichment (aeration) along a slope with tilt angles less than the angle of internal friction.

This is achieved by the fact that the proposed warehouse is made with an underground gallery located in the center of the warehouse. The gallery has the shape of a tent, in the sloping walls of which the side chutes are made. Inside the gallery, there are mounted air-jets, which are adjacent to the air flow, combined into one with continuous air paths. Air tracks are made with a soft porous coating, for example, from a whole-woven non-rubberized

conveyor belt laid on perforated steel sheet. The gallery also serves as the base of the columns supporting the floor.

FIG. 1 shows the scheme of the proposed warehouse - transverse section; in fig. 2 - the same, longitudinal section; in fig. 3 - warehouse, plan view; in fig. 4 - technological scheme of the warehouse.

The warehouse consists of a hip gallery / made of closed reinforced concrete links. The gallery has side openings 2, in which air leakages 5 pass, combined into one with continuous air tracks 4. Air tracks are made with a soft porous cover 5, for example, from a whole-woven non-rubberized conveyor belt, laid on a perforated steel sheet 6 of the duct. The air duct is divided by transverse partitions into three sections with an independent supply of compressed air to them by pipes 7, from air line 8.

Inside the aerotechka there is a cantilever flap 9 for controlling the amount of cement being discharged.

The cement that is discharged from the warehouse from the aerotechka 3 enters the 10 air deflectors installed in the underground gallery, then into the transverse air deflectors And, into the airlift 12, from it

pipeline 13 to the distribution funnel 14, from there to the channel / 5 delivery.

During the internal transfer of cement from the compartment to the compartment, the cement from the funnel 14 enters the loading and veneer 16 and from there via the side discharge link 17 into the warehouse.

The capacity of the warehouse is formed by bumps 18 with internal slopes 19 reinforced with concrete tiles. A tent 20 is placed on top of the embankments, resting on the foundation pillars 21 and columns 22, which in turn rests directly on the supporting closed links 23.

The warehouse has four compartments, formed by transverse embankments and collapsible reinforced folded partition walls 24.

The warehouse is loaded with cement or (from bunker cars) through receiving device 25, air duct 26, airlift 12 air duct 16, etc., or (from covered cars) with the help of a pneumatic loader through a receiving hopper 27.

Subject invention

A collapsible reinforced concrete semi-bunker warehouse for powder-like materials, such as cement, with an underground gallery of a tent shape, with side chutes located 11 in the inclined walls of the tent, characterized in that, in order to increase the storage capacity

dimensions, as well as ensuring, when unloading a warehouse, the movement of a material by saturating it with air, along a slope with a tilt angle less than the angle of internal friction, the warehouse is made from a centrally located

the gallery, also used as the base of the columns supporting the coating, and inside the gallery there are mounted airgel, which are adjoined to the aerotech, combined with continuous air tracks made with a soft porous coating, for example, one-piece non-rubberized conveyor belt, laid on a perforated steel sheet .
