Dosing and drug administration mechanism for ore dressing

Abstract

The invention discloses a dosing and drug administration mechanism for ore dressing. The dosing and drug administration mechanism comprises a dosing device and a drug administration device, wherein the dosing device comprises an inner box body, an outer ring body and a stirring device; the inner box body comprises a cylindrical barrel body with openings at upper and lower ends; end covers are arranged at upper and lower ends of the cylindrical barrel body; the outer diameters of the two end covers are greater than the outer diameter of the cylindrical barrel body; the end cover at the lower side and the cylindrical barrel body are internally molded; a plurality of first through holes are formed in parts, which are adjacent to the external circular surface, of upper end faces of the two endcovers at equal intervals in the peripheral direction; a plurality of inner annular grooves with semicircular cross sections are formed in the outer side face of the cylindrical barrel body at equalintervals. According to the dosing and drug administration mechanism, a plurality of rectangular cavities are arranged; the plurality of rectangular cavities are arranged so that pressure of a slurrymedicament in a grouting channel can be effectively ensured, and the slurry medicament can be uniformly injected into the inner box body from second through holes of the grouting channel; the drug administration precision is controlled through the changes of the volume and the stability of a drug administration dosage can be ensured.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and relates to a drug dispensing mechanism for mineral processing. Background technique [0002] In the liquid drainage beneficiation process, it is often necessary to add some specific flotation reagents to realize the separation of useful minerals and gangue minerals. The flotation agent is usually added to the flotation operation with a solution of a specific concentration, so the drug must be dispensed before adding the drug. The existing drug dispensing device is mostly a simple mechanical mixing tank, and a certain amount of slurry drug is directly fed from the top of the barrel. After adding water and stirring to form a certain concentration of chemical solution, it is transported to the mineral processing equipment through the pump at the bottom of the discharge pipe. In order to ensure a longer service life of the main shaft of the stirring impeller and to protect the bottom ...
