Inclined plate type device for preventing lump coal from being broken in process of entering bin

Abstract

The invention relates to an inclined plate type device for preventing lump coal from being broken in the process of entering a bin. Steel rails are paved at the top of the bin, so that a belt conveyor can move reversibly and the bin distribution requirement during high bin position can be met; and lump coal is gathered by a short inclined plate, the lump coal subjected to speed reduction can turn to slip along the inclined plate of the bin at a low speed by virtue of the gravitational potential energy of the lump coal, a buffering mechanism at the lower end part of the inclined plate of the bin performs secondary buffering speed reduction on the low-speed lump coal, and the lump coal slips into the storage along the conical slope of the bin by virtue of the gravitational potential energy of the lump coal, so that the process of the lump coal entering the bin without being broken and without broken points is implemented. The device can realize natural gathering, buffering speed reduction, low-speed slip and natural distribution and storage of the lump coal under the all-day unattended condition, realizes high utilization ratio of the bin volume and automatic warning in high storage position, overcomes the defects of the traditional device for preventing the lump coal from being broken in the process of entering the bin, solves the problem that the lump coal is broken when entering the bin, and has the characteristics of small investment, high efficiency and operating reliability.

Description

technical field [0001] The invention relates to an inclined plate type lump coal silo anti-breakage device, which belongs to the technical field of coal washing and processing. Background technique [0002] With the intensification of coal mining, the products produced by coal washing and processing cater to the market demand and bring huge economic benefits to the enterprise at the same time. Lump coal can be widely used in gas plants, refractory material plants, aluminum plants, ceramic plants, and some chemical plants. With the rapid development of chemical industries such as chemical fertilizers and methanol, the market demand for lump coal continues to increase, and at the same time, higher quality requirements are put forward for lump coal. Therefore, in order to meet market demand, it is an inevitable requirement and trend to improve the quantity and quality of lump coal products by adopting advanced scientific technical facilities and devices and strengthening the ...

AI Technical Summary

Problems solved by technology

The traditional storage devices for lump coal storage include: spiral chute, telescopic chute, mobile hopper, etc. These devices have been used in the process of lump coal storage in coal preparation plants, and have certain advantages. Dismantled and withdrawn from the stage of history, its common disadvantages are: ① heavy weight, too large structure, complicated operation, low work efficiency, high energy consumption, and heavy maintenance workload; ③ The flexibility is not enough, the lump coal can only be piled up in a small area when entering the warehouse, and cannot be used for storage in large warehouses
