Description

Square granary

Technical Field

The utility model relates to a grain storage device field, specifically a square granary.

Background

The metal granary used outdoors is divided into a round granary and an integrally welded square granary (called square granary for short), the round granary is higher in construction cost, and the integrally welded square granary is simpler in structure and lower in construction cost than the round granary.

However, the construction methods of the two types of granaries are complicated, the circular granaries need to build a deep foundation, and the construction period is long; the structural members and the barn plates required by the integrally welded square granary need to be processed and welded on site, the processing part is convenient, and the welding requirement is high in technology.

The prior assembled square granary basically solves the problems of the two granaries. However, most of the aforementioned silos employ loading grain into the silo from the top center of the silo via a conveyor system; the grain discharging mostly adopts a bottom center discharging form or a bottom multi-position discharging form.

However, grain accumulation modification angles are formed during the warehousing process due to the fact that grain has different grain sizes. Typically, the modification angle is in the range of 25-35 °. Grain particles and impurities with larger grain diameters fall to the outer edge of the storage bin along the formed modification angle, and grain particles with smaller grain diameters are accumulated in the middle area of the storage bin.

Therefore, the following problems still exist in the granary after continuous development and improvement:

firstly, because the conical top with the modified angle is formed on the grain pile when the traditional mode is adopted for loading the grain, the effective use volume of the granary is seriously influenced.

The grain size in the bin (II) is not uniformly distributed, and the grain discharging from the bin and the production processing directly influence the product quality of the subsequent grain production.

Thirdly, because the gaps between the large and small grain size materials are different, the ventilation, the air exchange, the insect killing and the like in the bin are seriously influenced, and the grains are greatly mildewed and grow insects in the middle area of the grain accumulation with the effective grain size; meanwhile, because grain particles and impurities with larger particle sizes fall onto the edge of the granary, the outlet is easily blocked when grains are discharged.

The granary capable of eliminating or obviously relieving the problems is developed, so that the granary is of great significance to grain storage, and has wide market prospects.
