Abstract

The present invention provides a pulp preparation device, wherein an agent and pulp can be mixed completely in the pulp preparation device. The pulp preparation device comprises a cylinder provided with a material inlet and a material outlet. An upper end inside the cylinder is provided with a tubular balanced material feeding apparatus communicated with the material inlet. The position of the pulp outlet arranged on the tubular balanced material feeding apparatus is provided with a spiral vortex mixing apparatus. A self-suction micro atomization mechanism is arranged above the spiral vortex mixing apparatus, and a pulp double-layer falling mixer is arranged below the spiral vortex mixing apparatus. The material outlet arranged on the bottom of the cylinder is provided with an inner sleeve material outlet pipe. With the present invention, the pulp dispersion system can be optimized, the agent and the pulp can be mixed completely so as to increase the collecting property and the foam uniformity of the agent; with the device, the power consumption is reduced, the consumption of the flotation reagent is reduced, the effect of the fine coal recovery rate is improved, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to an ore slurry preparer, in particular to a preparation device for fully mixing the ore slurry and the medicament. Background technique [0002] The pulp preparer is a device that disperses the flotation agent in the pulp, pre-contacts with the ore particles, adjusts the concentration of the pulp, and prepares the feed for the flotation machine before the pulp enters the flotation machine. The structure of the currently used pulp preparation device is very simple, and there are common shortcomings that the chemical and the pulp cannot be fully mixed, the chemical consumption is large, and the service life of the equipment is not long. Contents of the invention [0003] The purpose of the present invention is to provide a pulp preparer which can fully mix the medicament and the pulp. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a pulp preparer, which includes...
