Buffer breakage-proof flat bottom silo

Abstract

The invention relates to a buffer breakage-proof flat bottom silo, wherein, a central blanking barrel and a central column which are connected through a rigid mechanism are fixed in the center of the silo; an internal screw downspouting is arranged in the central blanking barrel and the central column is coiled with one or a plurality of screw downspoutings. In the buffer breakage-proof flat bottom silo in the invention, materials firstly pass through the internal screw downspouting, then pass through an external screw downspouting, and freely fall to the bottom part of the flat bottom silo by ensuring the minimum fall in a slipping manner, thus forming a pointed piling form with high center and low center peripheral part. When the materials account for 60% of the silo body space, a mobile distributing device is started to locate randomly, and a rotary distributing bridge does rotary movement along an annular orbit; blocky materials slip from the inner part of the silo center to the periphery of the center along the pointed piling gradient of raw materials and complete the distribution of the remaining 40% of the peripheral space of the silo. The invention effectively controls the fall of material free fall, increases blanking friction force, mitigates the impact of materials and reduces flow rate, thus being in particular applicable to the storage of blocky materials.

Description

technical field [0001] The invention relates to a device for storing bulk materials, which enables the materials to slide into the warehouse to prevent the block materials from being broken due to free fall without buffering. Background technique [0002] At present, there are basically the following structures to reduce the crushing of bulk materials: [0003] One is to reserve a coal drop hole on the outer wall of the silo and add a spiral chute device. This device has a good anti-shattering effect. The biggest advantage is that after installation, no power is needed, and the material slides on the spiral chute by its own weight and speed, resulting in The strength of the silo is reduced, the storage space cannot be fully utilized, or it is only suitable for silos with a higher height and a smaller diameter. Or the silo is set up as two floors inside and outside, and the "intermediate silo" is used to alleviate the gravity impact of the material, but the cost of building ...

AI Technical Summary

Problems solved by technology

The silo buffer distribution device of the present invention can make the material reach the distribution slewing bridge in a sliding way through the spiral slideway, and then freely fall to the surface of the material layer in the silo with the smallest drop, but the structure is complicated and maintenance is difficult
