Description

Loading equipment for artificially synthesizing bauxite Technical Field The invention relates to the technical field of bauxite transportation, in particular to loading equipment for artificially synthesizing bauxite. Background The artificially synthesized bauxite is a novel refractory raw material prepared from bauxite raw material serving as a main raw material through the processes of proportioning, grinding, balling, calcining and the like, has the advantages of high volume density, low porosity, good thermal stability and the like, and is widely applied to the high-temperature industrial fields of steel, cement, ceramics and the like. In the production process of artificially synthesized bauxite, after the finished raw materials are calcined and cooled, the finished raw materials are required to be transferred to a transport vehicle through a conveying line so as to be stored in a warehouse or sold in an outward transport way. At present, the loading operation of artificially synthesized bauxite mostly adopts the following modes that raw materials are conveyed to a loading station through a belt conveyor or other conveying equipment and directly fall into a transport carriage through a chute or a telescopic chute. However, this conventional loading method has the following disadvantages in practical application; Firstly, bauxite clinker is rubbed and collided with each other in the conveying and falling processes, and a large amount of dust is easily generated due to the fact that dust possibly adheres to the surfaces of raw materials. The dust not only seriously pollutes the working environment and endangers the occupational health of operators, but also causes raw material loss and increases the production cost; In addition, although some existing loading equipment is provided with a dust removing interface, the dust removing effect is not ideal because the dust removing points are unreasonably arranged or the air suction direction and the material flow direction are mutually interfered. For example, the dust removing port is directly arranged near the blanking point, so that part of fine particle materials are easily sucked away together, the raw materials are wasted, and if the air suction speed is too low, the dust can not be effectively trapped.
