High-speed disc type dehydrator

Abstract

The invention discloses a high-speed disc type dehydrator, and belongs to the field of preparation equipment. The high-speed disc type dehydrator comprises a motor, a drum cover shell, a transmission device and a drum component, wherein the drum component is positioned in the drum cover shell, and comprises a main shaft, a working disc component and a drum; the main shaft is vertically inserted in the vertical center position of the drum, and is sealed and fixedly connected with the lower end of the drum; the upper end of the drum is an opening; the working disc component is mounted in the drum; and the motor is connected with the main shaft through the transmission device. Pulp with a concentration of 5-7% can be concentrated and dehydrated by the equipment to change the concentration about 40%. In particular, after fine particles about -10 microns are treated by the equipment, overflow solid contents thereof are lower than 0.5%, so that such advantages as obvious concentration effect, high production efficiency and small floor area are achieved; and polished fine tailings can be concentrated before a floatation section, so that the tailing transport cost is reduced, and the water recycling rate is improved.

Description

technical field [0001] The invention belongs to the field of mineral processing equipment, in particular to a high-speed disc dehydrator. Background technique [0002] In wet processing plants, the mineral processing products (concentrate, medium ore and tailings) exist in the form of slurry in most cases. In order to facilitate further processing and smelting, and fully recycle water resources, there are certain requirements for product moisture. Mineral dressing tailings, in order to facilitate transportation and stacking and use backwater, the tailings also need to be concentrated and dehydrated. In the mineral processing production process, sometimes subsequent operations also have concentration requirements for the products of the previous operation, so dehydration of mineral processing products is an indispensable production link. [0003] The pollution sources of mineral processing plants include waste water, waste gas and waste residue, among which waste water poll...
