Description

The disadvantage of all loading bunkers is the presence of inclined walls in bunker installations, which in view of the oncoming flow of materials to the mouth (gate), the wedging of bulk materials, the formation of internal compacted vaults and the overlying layers hang. In order to eliminate hang-ups, a mechanical impact on the material is always required (pushing through, destruction of the roof).

The proposed device is aimed at helping to eliminate the possibility of formation of arches and sticking of materials, and thereby facilitate the release of material through the gate. For this, the bunker is divided into a number of compartments by partitions in the form of hinged shields, which, for the purpose of heating the loaded material, can be made box-shaped for admitting their heated gaseous or other agent into the cavity through hollow axles supporting the shields.

In FIG. 1 depicts a longitudinal section of the hopper; FIG. 2 is a cross-section of it.

Inside the bunker, mainly above the shutter, and at large distances between the closures and between them, are freely suspended on hinges / flat shields A. Shields A are located under the beams of the bunker rack or under

grate bars from rails, usually arranged above bunkers on rails, and therefore protected from direct impacts of materials falling into the bunker.

Thus, the entire volume of the bunker is divided into a number of vertical compartments by mi-shields L for a number of vertical compartments, the formation of arches and the freezing of materials in which it is impossible. When the shutter is opened, the pillar of material in the compartment freely falls through the open shutter, and the material is also carried along to a number of compartments separated by shields.

If the lowering of materials through the valve is uneven, i.e., the material from the compartment located above the valves first fails, then when lowering the upper layer of this column under the lower edge D of the shield, the latter, as a freely suspended one, will not hold the column of material located in the compartment and will be moved to position B by the material of this compartment falling to the gate.

The use of dividing panels allows the heating of materials, in the bunker, as the most rational way of using heat.

For this purpose, the proposed separation shields A are made in the form of closed flat boxes in which cavities are located in the cavity to form channels for the passage of heated gaseous or liquid agent through them. When steam is used, a device should be provided for the release of condensation water,

The heated agent is supplied and discharged through hollow axles connected to the shields by conventional clutches so that each shield has the ability to tilt in one direction or another, independently of the other shields.

The thickness of the shield sheets depends on the size of the hopper, the depth and pressure of the heated gaseous or liquid agent. The rigidity of the entire shield can be increased by longitudinal ribs on the shield. Shield weight should be minimal. The loss of the capacity of the bunker from 1CITS is negligible compared with the volume of the bunker.

The subject matter of the invention.

Claims (2)

1. A loading bunker, characterized by the use in us of a number of sections that divide it into compartments in the form of shields A (Fig. 1), freely suspended from above on hinges G in order to allow them to freely deflect when pressure changes along the other their side and so contribute to the elimination of blockages and arches. 2. Variations of the bunker according to claim 1, characterized in that the shields A (Fig. 2) are made box-shaped for admission into their cavity, for the purpose of heating the heated gaseous or other agent supplied and withdrawn in the usual way through hollow axles supporting the shields. ±) and and g .: XS ± OS OS ± Z t SSr. ± r | 55 4 5 | % t 1 N Fig 2 A, - rs t l Si .- J 5 rt 3 W /
