Fluidized discharge ventilation system for grain steel silos

Abstract

The invention discloses a fluidized discharge ventilation system for steel grain silos, which comprises a grain steel silo body, and the grain steel silo body is composed of a silo roof, a silo wall and a silo bottom by way of an enclosing mode; the silo roof is provided with a vent hole, and the silo bottom is of a conical-surface structure that the center of the silo bottom is lower than the periphery of the silo bottom; the central position of the silo bottom is provided with a discharge outlet; acclivitous V-shaped troughs are arranged evenly along the discharge outlet towards the silo wall, and the lower part of the silo body is provided with an annular air-duct along the silo wall, wherein the annular air-duct is communicated with an external air source; branch air ducts communicated with the annular air-duct are arranged below the V-shaped troughs, the branch air ducts are communicated with the cavity of the silo body by a sieve plate arranged at the bottom of the V-shaped troughs, and the air inlet of each branch air duct is provided with an air door. The system of the invention has the advantages that: for the grain steel silo with large diameter, the height of a foundation platform of the grain steel silo can be effectively reduced, the civil engineering cost can be reduced, the phenomenon of large slope filling can be avoided, and the problem of artificial silo emptying can be solved; and when the grain silo is completely filled, the fluidized discharge ventilation system also has the effects of ventilation and cooling according to the situation of grains and the weather conditions, thereby ensuring safe grain storage.

Description

technical field [0001] The invention relates to a steel plate silo for material storage, in particular to a fluidized discharge ventilation system for a large-diameter steel plate silo. Background technique [0002] At present, with the rise of my country's grain processing industry, the construction of vertical silos is developing rapidly, and the application of steel silos is more extensive. Steel silo turnover warehouses can be seen everywhere in grain processing (flour, oil, feed), chemical industry, brewing, pharmaceutical and other industries, and the construction scale is getting larger and larger, and the diameter of steel silos is also getting bigger and bigger. Only in this way can the construction investment cost per ton of granary be reduced, and good economic and social benefits can be produced. However, due to the increase in the diameter of the steel silo, in order to ensure smooth unloading (grain) material, it is necessary to increase the height of the base...

Problems solved by technology

However, due to the increase in the diameter of the steel silo, in order to ensure smooth unloading (grain) material, it is necessary to increase the height of the base platform of the steel silo, which not only increases the construction cost, but also requires a larger slope filling angle, which reduces the need for a single silo. Capacity, but also need to manually clear the warehouse, increasing the storage cost
