Material conveying device applied to coal blending machine

Abstract

The invention discloses a material conveying device applied to a coal blending machine. The device comprises at least one set of weighing mechanism and conveying mechanism which are matched, the weighing mechanism comprises a weighing belt and a seal unit for completely sealing the upper half part of the weighing belt, a feeding opening of the seal unit communicates with a discharging opening of astock bin of the coal blending machine, a discharging opening of the seal unit communicates with a feeding opening of the conveying mechanism, the conveying mechanism comprises a closed shell and a material conveying belt fixedly mounted in the closed shell, a blockage clearing unit used for preventing material blockage is arranged at the position, above the material conveying belt, in the closedshell, the device is novel in design, ingenious in structure and convenient to use, in the coal blending process, the phenomenon of dust diffusion can be avoided, the damage of the coal dust to the work environment can be avoided from the source, the device is suitable for the coal blending machine and used for weighing single kind of coal in all stock bins of the coal blending machine, and the weighed single-kind coal is conveyed to a breaking stirring device 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
