AI Technical Summary

Technical Problem

Existing spiral chutes are unstable in the introduction of ore slurry in fine-grained mineral beneficiation, requiring manual guidance, which is cumbersome and dangerous, affecting beneficiation efficiency and safety.

Method used

A flow diversion mechanism, including a spiral track and a flow diversion box, is installed inside the spiral chute. Stable flow diversion is achieved through drive cone wheels and motor gear transmission. Combined with a climbing mechanism, a safe maintenance passage is provided, and the support structure ensures the stability of the equipment.

Benefits of technology

It achieves uniform distribution and continuous sorting of minerals in the sluice, improves mineral processing efficiency and safety, reduces the risk of manual operation, and enhances the portability and flexibility of the equipment.

Abstract

The utility model relates to fine-fraction mineral medium spiral chute beneficiation equipment which comprises a spiral chute, a drainage mechanism is arranged in the spiral chute and comprises two spiral tracks and a drainage box, the two spiral tracks are arranged on the outer spiral inner side wall and the inner spiral inner side wall of the spiral chute respectively, and the drainage box is arranged in the spiral chute. The drainage box is slidably installed between the two spiral rails through driving cone pulleys, the driving cone pulleys are installed on the two sides of the drainage box, clamping plates are connected to the two sides of the drainage box, a drainage roller is rotationally connected between the two clamping plates, and the drainage roller makes contact with the inner bottom face of the spiral chute. According to the equipment, through ingenious combination of the spiral chute and the drainage mechanism, minerals can be evenly distributed on the spiral chute and continuously flow downwards along with water flow, and therefore efficient drainage and accurate separation of the minerals are achieved.
