Description
Technical Field
[0001] The utility model belongs to the technical field of mechanical equipment, and further belongs to the technical field of transportation equipment, and specifically relates to a material mixing device for a belt conveyor which has a simple structure, is reliable to use, and can effectively prevent materials from being sucked away. Background Art
[0002] In the production of sintered pellets, the materials used are iron ore concentrate, dust removal ash, flux, and bentonite. The particle size of the materials is relatively fine, generally reaching an average of more than 90% at -200 mesh. In addition, the dust removal ash, flux, and bentonite contain less water, which is easy to generate dust. These materials are batched according to a certain ratio using an electronic scale and need to be transported by a belt conveyor, and different types of materials are arranged in layers on the cross section of the belt conveyor. For example, in a steel company's belt roasting machine pellet production line, the bottom layer of materials on the belt conveyor in the batching room is iron ore concentrate powder with high moisture content and specific gravity, the middle layer is dust removal ash and flux with low moisture content and low specific gravity, and the upper layer is bentonite with low moisture content and low specific gravity. The distribution of materials is as follows: Figure 7 As shown. Due to environmental protection requirements, a dust collector is installed above the belt conveyor. During the operation of the belt conveyor, the light-weight materials in the middle and upper layers are easily sucked away by the dust collector's suction hood. At the same time, the operation of the belt conveyor will generate dust, which will affect the ratio accuracy of the materials and pollute the on-site environment. Therefore, the key to solving this problem is to research and develop a belt conveyor material mixing device with a simple structure, reliable use, and the ability to effectively prevent materials from being sucked away.
