AI Technical Summary

Problems solved by technology

[0005] The disadvantage of the round pool rake thickener is that its underflow concentration is not high, which cannot meet the requirements of outputting high-concentration products; and the deep cone thickener has high construction and operation costs due to its structural characteristics.

Embodiment Construction

[0017] see figure 1 , figure 2 , the present invention is a semi-deep cone thickener, which has a thickener bracket 9, a tank body is installed on the thickener bracket, a crossbeam 1 is arranged on the upper part of the tank body along the diameter direction, and a circle of overflow grooves is arranged on the upper part of the tank body along the circumferential direction 2. A number of overflow outlets 18 are provided on the overflow tank, and a feed cylinder 15 is provided at the center of the pool body. The pool body is composed of an upper cylinder 3 and a lower double-cone structure. The lower double-cone structure It is composed of an inverted large cone 5 and an inverted small cone 6, wherein the large cone is located above the small cone, and the angle between the conical surface of the large cone and the horizontal plane is 8-12°. The inclination angle between the conical surface of the cone and the horizontal plane is 50-60°, the preferred angle is 55°, the upper...

Abstract

The invention relates to a half-deep-cone thickener. The half-deep-cone thickener is provided with a thickener support, a pool is formed in the thickener support, a beam is arranged on the upper partof the pool in the diameter direction, a feeding barrel is arranged at the center of the pool, and the pool is composed of an upper part cylinder and a lower part double cone structure, wherein the lower part double cone structure is formed by connecting an inverted large cone and an inverted small cone; a driving device is arranged on the part, located at the center of the pool, on the beam, a transmission vertical shaft which is arranged downwards is in transmission connection with the driving device, a rake device and a stirring device are arranged on the transmission vertical shaft, the rake device and the stirring device are integrated together through a flange and are driven to run by the driving device respectively and simultaneously, and the rake device is arranged in the inner space of the large cone, while the stirring device is arranged in the inner space of the small cone. The thickener is novel in structural design and obvious in use effect and has high actual use and popularization values.

Description

technical field [0001] The invention relates to the technical field of thickening or clarifying equipment, in particular to a semi-deep cone thickener. Background technique [0002] Currently, there are two main types of thickening and clarification equipment used for continuous work: one is the traditional cylindrical pool rake thickener, also known as the ordinary thickener, which consists of a circular thickening pool and a rake mud scraper. Most of the composition; the solid particles suspended in the pulp in the thickening tank settle under the action of gravity, and the upper part becomes clarified water to separate the solid and liquid; the mud deposited at the bottom of the thickener is continuously scraped by a rake scraper It is discharged from the ore outlet in the center of the bottom of the pool, while the clarified water overflows from the upper edge of the thickening pool. [0003] The other type is the deep cone thickener, which consists of a cylinder and a ...
