W-shaped bottoming cycle airflow pneumatic flotation machine

Abstract

The invention discloses a W-shaped bottoming cycle airflow pneumatic flotation machine. The W-shaped bottoming cycle airflow pneumatic flotation machine comprises an ore pulp receiving groove, a stirring mechanism which is located at the upper end of the ore pulp receiving groove and used for stirring ore pulp in the ore pulp receiving groove, and scraper boards which are located at the upper end of the ore pulp receiving groove and used for scraping off mineralized bubbles, by fixedly installing an air inlet pipe at one end of a first installation hole, the air inlet pipe communicates with a second protective shell, moreover, the top end of the air inlet pipe communicates with an air blower, and a circulating air pipe communicates with the second protective shell, so that when air is pressed into the air inlet pipe by the air blower, the air enters the ore pulp receiving groove when under pressure; and when the air and the ore pulp cannot be completely mixed, the air which is pressed in is pressed into the ore pulp receiving groove from the circulating air pipe by the air blower again when under pressure, and thus cycle airflow is generated, so that the defect that when a traditional pneumatic flotation machine presses external air in a single direction, enough air cannot be guaranteed, and full contact among mineral grains and bubbles cannot be guaranteed, so that bubble refining is affected is solved, and the refining efficiency is improved.

Description

technical field [0001] The invention relates to the structural field of an inflatable flotation machine, specifically a W-shaped bottom circulating airflow inflatable flotation machine, belonging to the application technical field of a circulating airflow inflatable flotation machine. Background technique [0002] The flotation machine is suitable for the separation of non-ferrous and ferrous metals. Generally, the flotation machine is driven by the V-belt drive of the motor to rotate the impeller, which generates centrifugal action to form a negative pressure. At the same time, the foam is refined so that the minerals adhere to the foam and float to the surface of the slurry to form a mineralized foam. [0003] In the traditional inflatable flotation machine, the inflatable mechanism communicates with the slurry tank through the air guide tube when in use, and the air flow enters the slurry tank in one direction along with the air guide tube to mix with the pulp. The tradit...

Problems solved by technology

[0004] The purpose of the present invention is to provide a W-type bottom circulating airflow inflatable flotation machine to solve the traditional inflatable flotation machine. When in use, the inflatable mechanism communicates with the slurry tank through the air guide tube, and the air flow enters the slurry tank in one direction with the air guide tube. The traditional inflatable flotation machine cannot ensure enough air when the external air is pressed in one direction, that is, it cannot ensure that the ore particles and the air bubbles can fully contact, which affects the efficiency of the refined foam; when the refined foam floats After the mineralized foam is formed on the surface of the pulp, the traditional inflatable flotation machine uses a scraper to scrape out the useful foam. The scraper is mostly a plate directly installed on the rotating shaft, and its scraping efficiency is low. When mineralized foam More often, the technical problem that the foam cannot be scraped out in time
