A fast foam scraping device for stabilizing flotation flow field

Abstract

The invention discloses a quick foam scraping device for stabilizing a flotation flow field, and belongs to the field of flotation machines. The quick foam scraping device for stabilizing the flotation flow field comprises a tank, wherein a large foam collection box is fixedly connected with the left end of the tank, symmetrical support rods are fixedly connected with two ends of the tank and connected with chain wheels through rotating shafts, and the two chain wheels are connected through a chain belt. According to the device, motor driving shafts rotationally connected to corresponding fixed plates can drive corresponding rotating rollers to rotate, and when the rotating rollers rotate one cycle, limiting slide blocks drive moving plates to move back and forth one cycle under the action of the limiting slide blocks with effects of limiting and driving in circumferential closing limiting slide grooves in the rotating rollers, so that the moving plates drive second foam scrapers to move front and back, and foam accumulated gradually in front of first foam scrapers is scraped into small foam collection boxes on both sides. Floating blockage of the mineralized foam is effectively avoided, the foam can quickly float to the upper surface, and the mixing effect of air and ore pulp in the tank is ensured.

Description

technical field [0001] The invention relates to the field of foam scraping in the flotation flow field of a flotation machine, in particular to a foam rapid scraping device for stabilizing the flotation flow field. Background technique [0002] Flotation is the main method of separating fine-grained minerals. Almost all minerals can be separated from ores by flotation. At the same time, secondary resources and non-mineral resources can be processed. The flotation machine is driven by a motor V-belt to drive the impeller. Rotation produces centrifugal action to form a negative pressure. On the one hand, it inhales sufficient air to mix with the pulp, on the other hand, it stirs the pulp to mix with the medicine, and at the same time refines the foam, so that the minerals adhere to the foam and float to the pulp surface to form mineralized foam. Then adjust the height of the gate to control the liquid level so that the useful foam is scraped off by the scraper, but when the sc...

Problems solved by technology

[0004] Aiming at the problem in the prior art that the foam scraped by the scraper increases, and the mineralized foam is hindered from floating to the upper surface quickly, resulting in a low mixing effect between the air and the pulp in the tank, the purpose of the present invention is to provide a method for The foam rapid scraping device that stabilizes the flotation flow field can effectively prevent the mineralized foam from being blocked from floating up, ensure that it can quickly float to the upper surface, and ensure the mixing effect of the air in the tank and the pulp
