Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of stock bin anti-blocking, particularly relates to a stock bin integrated rotary anti-blocking device. BACKGROUND
[0002] With the increasing development of industrial and agricultural production, super large stock bins, as the core equipment for material storage and transfer, are widely used in many fields such as mining, metallurgy, power, chemical industry, building materials, etc. Taking the mining industry as an example, super large stock bins need to store a large amount of ore to provide stable raw material supply for subsequent crushing, beneficiation and other processes; in the power industry, large coal bins are used to store coal to ensure the continuous and stable operation of thermal power generation. The capacity of these super large stock bins can reach several thousand or even tens of thousands of cubic meters, which can meet the demand of large-scale production for material storage and greatly improve the continuity and efficiency of industrial production.
[0003] However, in actual operation, super large stock bins face a very tricky problem of blockage. Due to various factors such as material viscosity, humidity, uneven particle size distribution, and unreasonable design of stock bin structure, material in the stock bin is prone to form blockage, bridging, wall hanging and other blockage phenomena. Once blockage occurs, it will not only cause material to discharge poorly, affecting the normal operation of the subsequent production process and reducing the efficiency of the entire production system, but also may cause a series of serious consequences. For example, in cement production, stock bin blockage may cause cement production equipment to idle or overload, resulting in equipment damage; in the grain storage industry, blockage may cause grain accumulation to deteriorate, causing huge economic losses. According to incomplete statistics, the economic losses caused by industrial production interruption due to stock bin blockage problem reach tens of billions of yuan per year.
[0004] The existing technology can alleviate the stock bin blockage problem to some extent, but still has many limitations. Although the vibration anti-blocking technology can promote material flow to some extent, long-term vibration may cause fatigue damage to the stock bin structure, shorten the service life of the stock bin, and the vibration effect is not good for materials with high viscosity or high humidity. The impact force of air cannon unblocking technology is difficult to control accurately, which may cause damage to the stock bin wall, and frequent use of air cannon will consume a large amount of compressed air, increasing the operating cost.
