Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mine tailings treatment, more particularly to a mine tailings harmless treatment device. BACKGROUND

[0002] Tailings are the product with low useful components after the main components of the raw ore are enriched in the concentrate after the selection operation, and the secondary components of the ore or other associated metals are recovered. Mine tailings have always been one of the difficult problems, and the pollution problem of construction waste is one of the big pollution problems.

[0003] After searching, the utility model patent with publication number CN216835850U discloses a mine tailings harmless treatment device. The mud tank is arranged at the front end of the conveying belt, and the mud inlet cavity is arranged at one side of the middle part of the mud tank. The ore tail mixture is pumped into the mud inlet cavity by the feeding pipe at a certain pressure to drive the impeller in the mud inlet cavity to rotate, so that the impeller drives the mud discharge mechanism arranged in the mud tank to rotate synchronously through the transmission assembly, so as to push the mud water in the mud tank into the arc-shaped mud guide plate on one side of the mud tank, and then into the conveying belt through the water-permeable guide plate at the end of the arc-shaped mud guide plate. The above technical scheme is adopted to improve the pre-filtering efficiency of the ore tail mud by double filtering. At the same time, by arranging the impeller and the mud discharge mechanism, the mud water in the feeding pipe entering the mud inlet cavity drives the impeller to drive the mud discharge mechanism to rotate synchronously, which saves energy and reduces consumption, and reduces the problem of tail mud sedimentation and accumulation in the mud tank, greatly improving the harmless treatment efficiency of mine tailings.

[0004] However, the above-mentioned patent still has the following disadvantages: although the pre-filtering efficiency of the ore tail mud is improved by double filtering, the tail mud entering the mud tank will be scraped by the scraper, and the water in the tail mud will also be scraped away, which is not convenient for the water in the tail mud to pass through the filter net; at the same time, it takes a certain time for the sewage in the water-permeable guide plate to pass through, which also affects the pre-filtering effect, and the practicability is poor; in addition, the tailings falling on the conveying belt are easy to accumulate, which affects the conveying effect of the conveying belt. Therefore, we propose a mine tailings harmless treatment device. UTILITY MODEL CONTENTS
