Influencing Factors Of Unloading Rate Of Large Steel Silo
Steel Silo unloading rate refers to the material from the Steel Silo unloading the amount of total material as a percentage, also known as unloading rate. Unloading rate directly reflects the advantages and disadvantages of the practical performance of the Steel Silo, Steel Silo is the main performance indicators. When the Steel Silo out of the situation deteriorated, the library material, but the accumulation of more accumulation of material and the slowdown of the material caused by the effective reduction of steel plate volume, causing low unloading rate. Low unloading rate not only to make the Steel Silo can not play a good discharge effect, but also lead to the use of Steel Silo to reduce the economic benefits.
Large steel silo material using pneumatic conveying method, the material flow is the Steel Silo can be the key to the normal discharge. Material flow is subject to a wide range of effects. A long time backlog of materials, material humidity, the outside air and moisture into the library, the bottom of the warehouse wet, and some improper operation and so on are the reasons for the deterioration of material flow.
Material tonnage is too large, material level is too high, so that the material density increased, the bottom of the reservoir by the storage pressure increases, the material pressed the bottom of the library, fluidity performance. If the storage is not carried out for a long time on the material activation, resulting in the library material crushed, giving the material difficult. This phenomenon generally occurs in the material off-season when the material storage volume is much larger than the sale. In order to avoid the material for a long time storage and compaction, Steel Silo use side should regularly use the external circulation pneumatic system to loosen the bottom of the material.
Powder material itself is high water content, resulting in material discharge performance degradation or failure. In this regard, the user should strictly control the material before the storage of water content, the material moisture content to a minimum. The more dry materials, the better fluidization activity, the more difficult to compaction.
The bottom of the cement base layer is not completely dry, nor take effective moisture measures, the bottom of the library to the end of the floor material to increase the humidity of the material into a block, giving the material difficult. In addition, some Party use the unit ranging from the cone naturally dry air required to advance the feed, so the implementation of the bottom of the moisture control measures is particularly critical. Our company has decided to brush the surface of the guide cone waterproof moisture-proof material to improve the dryness of the bottom of the shop at the same time after the completion of smooth and clean moisture-proof layer of the surface is more conducive to the transport of materials.
In order to maximize the moisture-proof effect, the design institute, the Ministry of Quality Supervision, the research center, the purchasing department and the budget department participated in the test of 16 kinds of moisture-proof material samples. These materials can be divided into two components according to the composition, three components, according to the materials used can be divided into paint, epoxy resin, clay. Two parts of the material moisture-proof effect is also relatively good, but the materials used are basically their own manufacturers to prepare their own, taking into account the procurement and transport constraints, not used. Paint and mortar materials, the test results of poor moisture, not used. Taking into account the moisture-proof effect and economic applicability and other factors, approved by the various departments agreed to determine the use of three components of epoxy resin materials, the specific components are: E44 pure epoxy resin + T31 curing agent + acetone). The three components of the combination of materials are common chemical raw materials, easy to purchase in the area where the construction site, is conducive to saving transportation time, reduce transport risk. The construction of the moisture-proof waterproof material after the treatment of the bottom of the guide cone after the cement surface, before the installation of the bottom of the fluid rod. At present in the construction of the Steel Silo project is actively promoting the bottom of this library moisture measures, I believe that the future of the Steel Silo out of the system play a positive role.
