Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a mineral conveying device. Background Technology

[0002] Mineral conveying systems are devices used to transport bulk materials such as ore, coal, and sand from one location to another. These systems play a vital role in mining, construction, and logistics. The primary function of mineral conveying systems is to provide efficient, stable, and safe mineral transport solutions to meet ever-growing industrial demands. Modern mineral conveying systems typically employ various forms such as belt conveyors, chain conveyors, and screw conveyors. Among these, belt conveyors are widely used due to their simple structure, high transport capacity, and wide applicability.

[0003] Patent CN222409876U discloses a coal mine raw material conveying device, including a conveyor body, a water spray dust suppression device, and a water supply pipe. The conveyor body is a belt conveyor used to transport coal raw materials. The water spray dust suppression device is installed on a support in the conveyor body. The belt conveyor includes several inner roller conveyors, which form a rinsing zone on the belt. A rinsing spray pipe is provided on the lower side of the rinsing zone, and the rinsing spray pipe is connected to the water supply pipe. This invention sets a rinsing zone on the belt of the conveyor body, and the rinsing spray pipe connected to the water supply pipe is aligned with the rinsing zone to wash away the wastewater on the belt. A sinking zone is set on the belt of the conveyor body, and a wiping cloth is placed in the sinking zone to wipe away excess water on the belt. At the same time, heated air is introduced through the wiping cloth to dry the belt quickly.

[0004] In practical use, existing technologies can effectively wash away wastewater from conveyor belts by setting up rinsing zones. However, the rinsing spray pipes used to rinse the belts in these zones rely on external water supply pipes. This design requires a continuous supply of external water during operation, potentially leading to water waste. This is especially problematic in water-scarce areas, where it increases operating costs. Therefore, to address these issues, we propose a mineral conveying device designed for more efficient water resource utilization. Utility Model Content
