Flotation cell without transmission

Abstract

The invention discloses a flotation cell without transmission, which comprises a cell body and a pulp distributer; wherein, a feeding pipe arranged above the pulp distributer, and at least one venturi pipe is arranged under the pulp distributer; the venturi pipe is connected with a mineralized pipe which is connected with the pulp distributer, the bottom end of which is provided with at least onepiece of steel pipe, and a pulp ejector device is arranged at the bottom end of the steel pipe and is provided with a plurality of nozzles; the steel pipe is installed in the cell body, and a foam collecting groove is installed at the upper part of the cell body; the cell body is connected with a middling ore box by a pipeline; the flotation cell has high separation efficiency and low energy consumption, can meet the requirements of aluminum-silicon separation process of alumyte flotation desiliconization with different fractions, and has wide application scope.

Description

technical field [0001] The present invention relates to a flotation device, in particular to a flotation cell, which belongs to the technical field of separation of granular materials. Background technique [0002] At present, there are many types of flotation equipment, mainly including flotation machines and flotation columns. The development of flotation machines has a history of many years at home and abroad, and the technology is becoming mature. But its inherent disadvantages are obvious, such as: high energy consumption, large footprint and so on. [0003] Flotation column is a kind of flotation equipment developed in this technical field in recent years, which is famous for its low energy consumption, small footprint and relatively simple structure. In order to ensure the sufficient mineralization of air bubbles and a series of separation processes to be fully and effectively carried out, the height of the flotation column is generally 7 to 8 meters, and some are e...

Problems solved by technology

Moreover, under the effect of microbubble buoyancy, coarse particles cannot rise rapidly upward in a low turbulence state, nor can they quickly reach the foam layer and overflow into the foam tank, so the feature of "coarse particle flash floating" cannot be realized.

Moreover, since the air bubbles are mineralized in the column with a larger diameter, the dispersion of the gas in the column is uneven. Mineralization probability, thus prolonging the induction time of high-energy micro-bubbles and fine particles, reducing the attachment efficiency of fine particles and bubbles, making it impossible to achieve fine-grained high-energy micro-bubble flotation
