Ultra-long-distance large-volume aluminum oxide conveying method and system

Abstract

The invention belongs to the technical field of conveying equipment, and particularly discloses an ultra-long-distance large-volume aluminum oxide conveying method and system. Conveying modes are selected according to terrains, a tubular belt conveyor is selected in a long-distance uphill section, and a pneumatic chute system is selected in a downhill section or a gentle section; an air cushion belt conveyor is selected in a short-distance uphill section or for lifting requirements; and a transfer station and a dust removal device are arranged at the joint of the each conveying mode. The ultra-long-distance large-volume aluminum oxide conveying method and system have the beneficial effects that the method and the conveying system are provided, multiple conveying tools are comprehensively utilized, the application of the alumina powder in different terrains is realized by utilizing the combination of different characteristics of the multiple conveying tools, and the problems of ultra-long distance transportation of the alumina powder, flying dust in the transportation process and the like are solved, and the ultra-long-distance large-volume aluminum oxide conveying method and systemhave the characteristics of high efficiency, environment friendliness, high stability, small in suffering external influence and high comprehensive cost performance, and can meet the requirement of large-volume transportation.

Description

technical field [0001] The invention relates to the technical field of conveying equipment, in particular to an ultra-long-distance and large-capacity alumina transportation method, and also to an ultra-long-distance and large-capacity alumina transportation system. Background technique [0002] Alumina is an important industrial raw material, and the cross-border or long-distance transportation of alumina is mostly carried out by ship. Because alumina is a corrosive powder that is difficult to transport, and alumina powder is easy to leak, when unloading at the port, affected by factors such as sealing degree, dust, and strong wind, traditional grabs are used to transport the alumina. Aluminum powder is almost impossible to achieve. The current port treatment method for alumina is as follows: first use a special alumina ship unloader to unload the ship, then use the packing equipment to pack the alumina powder, and then transport it out by other transportation equipment su...

AI Technical Summary

Problems solved by technology

This alumina unloading treatment method has many restrictions on the geographical location of the port, the conditions of alumina collection and distribution, and the storage yard of alumina powder. It is only suitable for certain ports that are suitable for all aspects.

However, some ports with limited space are not suitable for this method; in addition, some alumina processing plants or storage yards are located several kilometers away from the port. The cost of the above method is extremely high and cannot meet the needs of enterprises. , currently there is no delivery and transportation method for this type of factory or storage yard

In addition, in the field of transportation, a distance of more than 1,000 meters is long-distance remote transportation. At present, the long-distance remote transportation of alumina powder is mostly carried out by means of transfer and connection of pneumatic chute. The pneumatic chute transportation system has high requirements on terrain. In complex areas, the cost of renovation and construction is extremely high, so the pneumatic chute system is generally used within the enterprise
