Description

A multi-stage cyclone thickener

technical field

The utility model relates to the technical field of flotation machines, in particular to a multi-stage cyclone thickener.

Background technique

Thickeners are widely used in the treatment of sludge, waste water and waste residues in metallurgy, mining, coal, chemical industry, building materials, environmental protection and other departments, especially for improving the utilization rate of return water and the concentration of underflow conveying and protecting the environment. Thickeners are usually divided into three categories: ordinary thickeners, inclined plate thickeners and high-efficiency thickeners.

Ordinary thickener (commonly known as rake thickener) is currently the most widely used thickening equipment in mineral processing plants. According to its transmission mode, it is divided into central transmission type (small diameter) and peripheral transmission type (large diameter). This type of thickener is simple in structure, easy to manage and reliable in production. However, due to its large diameter, it occupies a large area, requires a large investment in infrastructure, and has a low production capacity per unit area, and the concentration efficiency is not high.

The inclined plate (tube) type thickener is installed in the upper part of the cylindrical tank of the ordinary thickener, and many inclined plates (tubes) inclined to the center of the thickener are installed along the circumferential direction, and the angle with the horizontal is about 60°. These measures accelerate the separation of ore particles, strengthen the separation and sedimentation process, and improve the concentration efficiency. Compared with ordinary thickeners, it reduces capital investment. Its production capacity can also be increased by about 3 times. Due to its improved efficiency, the settlement area is greatly reduced, and it is more suitable for concentration and dewatering of fine concentrates and tailings. However, due to its complex structure, the inclined plate is easy to fall off, deform and age, and it is troublesome to maintain and operate.

The high-efficiency thickener is a thickener that has emerged and successfully applied later. In addition to the inclined plate in the round tank, it has a special flocculant adding mechanism. In fact, it is not a simple settling equipment, but a new type of dewatering equipment combined with the filtering characteristics of the mud tail. Its diameter can be reduced to 1/3-1/2 of the ordinary thickener, and the area is only 1/2 of the ordinary thickener. 9-1/4, while the processing capacity per unit area has increased by dozens of times, it is a new type of thickener that is increasingly widely used; however, due to the incomplete sedimentation of fine particles and the high content of suspended solids in the effluent, the quality of circulating water is difficult. It can better meet the requirements of production, and like the previous two thickeners, its transmission machinery and a large number of inclined plates with complex structures all increase the difficulty of maintenance and use.
