System and method for powder transportation

Abstract

The invention discloses a system and a method for powder transportation. An international standard container is used, the top of the transformed container is provided with a feeding port, and the bottom of a back door of the transformed container is provided with a discharging port. At the departure place, after the powder is loaded with zero pressure through the feeding port, the feeding port is sealed, the container serves as a multimodal transport device to transport the powder to the destination, a fluidized bed feeding tank is arranged at the destination, the discharging port of the container and an inlet of the fluidized bed feeding tank are aligned, and thereby the powder discharges automatically under own gravity. By means of the system and the method for powder transportation, an international standard container can be utilized directly and transformed, and thereby the advantages of simple production and strong generality are provided, and the purpose of international multimodal transportation is achieved. The method adopted is simple, the transportation efficiency of the powder can be improved greatly, the working environment is improved, the workers and workload are reduced, the transportation cost is reduced, and the market competitiveness is improved.

Description

Technical field [0001] The invention relates to the field of material transportation, in particular to a system and method for transforming a container structure to satisfy powder transportation. Background technique [0002] The existing transportation method for alumina ore powder is to load the ore powder into the ore powder hoisting bag and seal it, then hoist it to a truck, and then transfer it to a long-distance car or train by the truck, and transport the ore powder hoisting bag by a long-distance car or train. After reaching the destination, it is hoisted to the top of the corresponding container, and the slag bag is cut out of the blanking seam with a knife, and the slag powder flows into the corresponding container along the blanking seam, and finally the slag powder is transported to the storage tower by conveying equipment such as fluidized bed Used within. The existing transportation of alumina ore powder has serious drawbacks: 1. The efficiency of loading, sealing ...

AI Technical Summary

Problems solved by technology

There are serious disadvantages in the existing transportation of alumina powder: 1. The loading, sealing and transfer efficiency of the powder hanging bag is low, requiring a high degree of manual participation, high labor costs, extremely harsh working environment, and the accumulation of dust in the lungs to form pneumoconiosis Diseases and workers’ health are threatened. Mineral powder hanging bags are disposable products. Each mineral powder hanging bag costs about 50 yuan, and the additional cost of each transfer is 80-100 yuan / ton; 2. Transferring from trucks to long-distance vehicles The process requires auxiliary hoisting equipment and manual control, which increases labor costs. The hoisting process will cause dust leakage and affect the working environment. Cargo speed, long-distance vehicles occupying the road for a long time will affect the entry of other vehicles, and there is a gap between the mineral powder hanging bags to reduce the loading capacity; 3. The degree of dust raised during unloading is greater, and special hoisting tools are required to be hoisted to the top of the container for cutting Unloading, the working environment is even worse, and the floating waste of mineral powder is serious

The above-mentioned alumina powder transportation problem has not been effectively solved for a long time, which has a great impact on the environment of all enterprises in the industrial chain, increases production costs, endangers the health of workers and leads to high human resource costs. There is an urgent need for a reasonable and effective transportation method
