Technical Field

The invention belongs to the technical field of mineral processing equipment, and particularly relates to a bubble pushing mode of a reciprocating type automatic lifting flotation machine.

Background

The efficiency of forced discharge of the suspended froth products from the pulp surface directly affects the processing capacity and the separation efficiency of the flotation machine. The conventional way of discharging froth is to move the froth scraping plate circularly around the axis above the overflow weir of the flotation machine to scrape the froth near the overflow weir out of the tank body of the flotation machine. The contact area of the scraper and the foam is small, the foam scraping amount is an overlapping area of a scraper movement circumferential area and a flotation foam layer, the scraping amount is small, the foam far away from the circumferential area of the scraping foam plate is not discharged timely, and the processing capacity and the flotation effect of the flotation machine are severely limited. Along with the large-scale development of the flotation machine, the length and the width of the cell body of the flotation machine are amplified in an approximately equal proportion, so that the problem is more obvious.

In chinese patent CN200720190917.8, a bubble pushing device of a flotation machine is introduced, wherein the device effectively prolongs the adsorption of the foam to the valuable metal, so that the valuable metal is continuously enriched upwards along the inclined plane of the cone, and the concentrate foam is stably pushed into the outer ring foam groove, and finally the concentrate foam is completely flushed into the concentrate discharge port by the spray pipe water column, thereby achieving the purposes of balancing the sorting process, stabilizing the concentrate foam output and improving the concentrate sorting index, however, the skilled person in the art finds in the actual operation: when the device is used, the cone body is of an inverted structure, so that the generation speed is high, a spray type structure is adopted in a subsequent elimination mode, and when the device is used, concentrate which can be processed at one time is limited, so that the device is suitable for being used in a small range or in a small quantity, but is not suitable for a large mining area.
