Flotation machine equipped with abrasion-resistant main shaft and applied to production of ammonium phosphate salt mineral

Abstract

The invention discloses a flotation machine equipped with an abrasion-resistant main shaft and applied to the production of an ammonium phosphate salt mineral, and relates to the technical field of flotation machines. The flotation machine comprises a machine body, wherein a central cylinder is fixedly mounted at the center of an inner cavity of the machine body; a main shaft is inserted into thecenter of an inner cavity of the central cylinder; a pulp inlet is arranged on one side of the central cylinder; a pulp inlet pipe is fixedly mounted on one inner side of the machine body; one end ofthe pulp inlet pipe is fixedly connected with the pulp inlet; and a protective sleeve is movably mounted at the position, corresponding to the pulp inlet, of the outer surface of the main shaft. By adoption of the flotation machine equipped with the abrasion-resistant main shaft and applied to the production of the ammonium phosphate salt mineral, the main shaft can be effectively protected by theproactive sleeve against abrasion; the protective sleeve is detachable, and convenient to maintain and replace; through sealing gaskets, the main shaft can be effectively protected against abrasion and corrosion; convex thorns have excellent shock absorbing capacities; mineral pulp can be prevented from sinking to the bottom of a tank; a waterproof layer has the waterproof, corrosion-resistant and anti-impact effects; enough air can be sucked; the sucked air and the mineral pulp can be conveniently mixed; and accordingly, the use convenience and the bubble uniformity can be achieved.

Description

technical field [0001] The invention relates to the technical field of flotation machines, in particular to a main shaft belt wear-resistant flotation machine for producing ammonium phosphate minerals. Background technique [0002] The flotation machine is a kind of equipment widely used in mineral processing plants. When working, the motor drives the impeller to rotate, and a centrifugal effect is generated in the tank to form a negative pressure. The pulp in the cylinder is mixed. On the one hand, the impeller stirs the pulp to mix with the medicine, and at the same time refines the foam, so that the mineral sticks to the foam and floats to the pulp surface to form a mineralized foam. The foam is scraped out by the scraper driven by the motor. , where the slurry entering the central cylinder from the slurry inlet produces continuous scouring force on the main shaft, which accelerates the wear rate. In actual work, the service life of the main shaft is 6 months, resulting i...
