Description

Technical Field

[0001] The utility model relates to the technical field of tailings conveyors, in particular to a tailings conveyor which is easy to clean. Background Art

[0002] Tailings ponds are an important part of the production of mining enterprises. Tailings dry discharge is a new tailings disposal technology that has gradually emerged in recent years. It refers to the tailings slurry output from the beneficiation process, which is concentrated at multiple stages and then treated by dehydration and filtration equipment to form tailings slag with low water content, easy precipitation and solidification, and can be stored on site. The slag can be transported to a fixed location for dry storage through conveyor belts, bulldozers and other related facilities. In the production and operation of the tailings pond, the tailings slag after filtration and dehydration needs to be transported to the reservoir area through fixed or mobile conveyor belts, and the production operation must be smooth and safe.

[0003] However, the existing conveyor belt machine has certain defects. The tailings slag is piled up along the mountain line of the machine body. When the tailings slag piles up to a certain extent at the head unloading place, if the unloading device is not changed in time, a material blockage accident will occur. In addition, it is not easy to ensure that the slag on the conveyor belt falls completely, and it is easy for some slag to adhere to the conveyor belt. For this reason, we propose a tailings conveyor that is easy to clean. Utility Model Content
