Material conveying device applied to coal blender

Abstract

The invention discloses a material conveying device applied to a coal blender, which comprises at least one set of weighing mechanisms and a material transporting mechanism that cooperate with each other. The weighing mechanism includes a weighing belt and completely seals the upper half of the weighing belt. The sealing unit; wherein, the inlet of the sealing unit is connected with the outlet of the silo of the coal blender, and the outlet of the sealing unit is connected with the inlet of the material transport mechanism; the material transport mechanism includes a closed The casing and the material conveyor belt fixed inside the closed casing, and a blockage removal unit for preventing material clogging are also provided inside the closed casing and above the material conveyor belt. The invention is novel in design, ingenious in structure and convenient in use, and can avoid the phenomenon that coal dust diffuses in the process of coal blending, and avoids the damage of coal dust to the working environment from the root. The invention is suitable for coal blending machines, and is used for weighing single coals in each bunker of the coal blending machine, and transporting the weighed single coals to the crushing agitator of the coal blending machine.

Description

technical field [0001] The invention belongs to the technical field of coal transportation, and in particular relates to a material transportation device applied to a coal blender. Background technique [0002] At present, coking coal resources are scarce in all countries in the world, and the large-scale blast furnace requires higher and higher coke quality and stability, while strong caking coal in coking coal resources is becoming less and less. This contradiction is particularly prominent in our country. Therefore, according to the specific situation of my country's coal resources, all coking plants are committed to the research of coal blending schemes, that is, to combine several single types of coal with different grades in a certain proportion for coking, so as to rationally utilize the resources of coking coal in various regions and expand Reserves of coking coal. Coking with mixed coal can not only save high-quality coking coal, but also make full use of the coking...

Problems solved by technology

However, because the molecular structure of coal is not tight, when the coal in the silo falls into the weighing belt and the coal is transported by the mixing belt, it is easy to cause dust, which causes great damage to the workshop and other production sites. People work in this harsh environment for a long time, which will affect the health of the staff to a certain extent
