A pharmaceutical centrifugal atomization device and a complete set of flotation equipment based on shear atomization

Abstract

The invention discloses a pharmaceutical centrifugal atomization device and a complete set of flotation equipment based on shear atomization, including a pharmaceutical centrifugal atomization device, a double-wheel jet stirring device and a high-speed shear emulsification device; It has a pulp circulation inlet, an emulsifier inlet and an atomization inlet, and a pulp circulation outlet at the lower end. The atomization inlet is connected to the atomization outlet or the suddenly expanded atomization chamber through the atomization agent addition pipe; the emulsifier inlet is through the collection The emulsifier addition pipe is connected with the emulsifier outlet; the pulp circulation inlet is connected with the pulp circulation outlet through the pulp circulation inlet through the circulation pump; the invention realizes the effective utilization of energy, reduces energy consumption, and makes the collector Pre-react with the pulp to maintain the stability of the micro-bubble system. At the same time, multiple times of shearing and turbulent mixing make the micro-bubble system more balanced, provide sufficient contact opportunities for the efficient mineralization of the bubbles, greatly improve the mineralization efficiency, and improve the flotation process. Effect.

Description

technical field [0001] The invention relates to the technical field of mining machinery manufacturing, in particular to a complete set of flotation equipment for separating ore particles, and more specifically to a pharmaceutical centrifugal atomization device and a complete set of flotation equipment based on shear atomization. Background technique [0002] In the mineral separation process, for example, flotation is the first choice for the separation of fine-grained coal. At present, the mainstream flotation devices mainly include mechanical agitation flotation machines, jet flotation machines, flotation columns, etc. Before the election, it is usually equipped with auxiliary pretreatment devices such as pulp preprocessor, flotation agent addition equipment, and agent emulsification equipment, and the auxiliary pretreatment device is very important for efficient flotation of ore pulp. [0003] For the current flotation device and auxiliary pretreatment device, they are us...

Problems solved by technology

[0004] For improving the flotation efficiency, the addition method of the agent will greatly affect the mineralization system of the bubbles, and then affect the emergence efficiency. Currently, the commonly used flotation agents are mainly foaming agents and collectors. For the foaming agent, It is mainly to change the surface tension of the gas-liquid interface. The addition of the existing air bubble agent is mainly added during the flotation process of the flotation machine. Because it cannot be added uniformly and cannot effectively act on the gas-liquid interface, it will cause a lot of waste of the agent. And it cannot be quantitatively controlled to affect the flotation efficiency, and the phenomenon of "running fine" appears; for the collector, it mainly changes the hydrophobicity of the mineral surface, so that the floating mineral particles can effectively adhere to the air bubbles. The addition of the existing collector In the process, it is usually added directly, or added after a certain emulsification, and the collector after emulsification is more effective than direct addition in terms of reducing chemical consumption and improving flotation efficiency, but there may still be large energy loss and structural Complicated, occupying plant area and other phenomena
