Abstract
The invention discloses a fluid collaborative forced mixing tempering device and method which are suitable for surface modification of micro-fine mineral particles and mixed dispersion of a solid-liquid system and a liquid-liquid system. The fluid collaborative forced mixing tempering device comprises a vertical cylinder, a cross flow and impact flow generation system and an ore pulp circulation system; ore pulp and an agent are fed into the bottom of a barrel through an ore pulp feeding pipe, enter the ore pulp circulation system through a pre-circulation ore pulp discharging pipe and a circulation ore pulp discharging pipe at the top of a cone under the pumping and sucking action of a circulation pump, are fed into the vertical cylinder through the cross flow and impact flow generation system, and form a high-speed impact flow and a forced shearing cross flow in the vertical cylinder, thus the particles and the agent in the cylinder are fully mixed and dispersed, the surfaces of theparticles are scrubbed in a forced mode, and adsorption of the agent on the surfaces of the particles is strengthened. The fluid collaborative forced mixing tempering device is simple in structure, convenient to use, high in energy utilization efficiency, and high in mixing and disperse efficiency of the particles and the agent, the surfaces of the particles are scrubbed in the forced mode, the adsorption effect of the agent on the surfaces of the particles is strengthened and good, and thus efficient modification of the surfaces of the particles is achieved.
Description
technical field [0001] The invention relates to a fluid synergistic forced mixing conditioning device and method, especially suitable for the surface modification of fine mineral particles and the mixing and dispersion of solid-liquid systems and liquid-liquid systems. Background technique [0002] The surface modification of fine mineral particles or coal particles is the basic premise and guarantee for their efficient mineralization and separation. At present, mechanical agitation is mainly used to pretreat the pulp and chemicals, that is, the particles and chemicals are realized under the agitation of the stirring impeller. The mixing and dispersion of the agent and the adsorption of the medicament on the surface of the particle, in which the action of the fluid runs through it. However, traditional mechanical agitation is mainly based on the dispersion and mixing of particles and agents, which is insufficient in enhancing the spreading and adsorption of agents on particl...
