Tailing retreating type ore drawing device

Abstract

The invention discloses a tailing retreating type ore drawing device which comprises a crawler-type walking trolley, a fill dam and a tailing pond dry beach. A hydraulic telescopic rod is mounted on the upper surface of the crawler-type walking trolley, the telescopic end of the hydraulic telescopic rod is connected with a tailing conveying pipe through a mounting frame, an extension pipe is arranged on the front side of the right end of the outer side face of the tailing conveying pipe, and a sealing cover is arranged on the left end face of the tailing conveying pipe. According to the tailing reverse type ore drawing device, formation of a fine fraction tailing discharge dry beach can be promoted, the length of the dry beach is effectively prolonged, the gradient of the dry beach is increased, safe and stable operation of a tailing pond is ensured, meanwhile, operation and maintenance are convenient, and blockage in the pipeline operation process can be effectively avoided; the moving convenience of the device can be effectively improved through the crawler-type walking trolley, the tailing conveying pipe can conveniently move along the top of the fill dam, and the screw motor can push away solid particles accumulated at the end of the tailing conveying pipe by driving the discharging screw to rotate.

Description

technical field [0001] The invention relates to the technical field of beneficiation, in particular to a tailings reverse type ore drawing device. Background technique [0002] The mining of gold ore belongs to the fine-grained encapsulated gold-bearing ore. The grinding fineness of gold ore in the concentrator is relatively high. After the tailings are classified, the coarse-grained tailings are used for underground goaf filling, and the fine-grained tailings are discharged. Into the tailings pond, the fineness of the fine-grained tailings of 200 mesh is as high as 95%. Generally, the conventional discharge method of such fine-grained tailings will lead to very gentle tailings deposition slope, short dry beach length, high reservoir water level, and difficulty in consolidation of ore sludge for a long time, which will affect the stability of the dam body. [0003] As the tailings discharge is consolidated on the shoal, the position of the slurry outlet of the tailings draw...

AI Technical Summary

Problems solved by technology

Generally, if such fine-grained tailings are discharged in a conventional way, the tailings deposition slope will be very gentle, the length of the dry beach will be short, the water level in the reservoir will be high, and the ore slime will be difficult to consolidate for a long time, which will affect the stability of the dam body.

[0003] As the tailings discharge consolidates on the material bank, the slurry outlet of the tailings drawing device needs to change its position regularly. In the prior art, the common method is that workers move the tailings discharge pipe by hand to change its position. Or install an extension pipe at the tailings discharge port, which is time-consuming and labor-intensive to operate, and the discharge pipe needs to stop the ore discharge during the operation, which affects the production progress; at the same time, the existing tailings discharge device will The particles contained in the ore are easy to accumulate in the ore-drawing pipeline, causing the pipeline to be blocked; based on this, the present invention designs a tailings retrograde ore-drawing device
