Description
Technical Field
The utility model relates to a flotation machine technical field, in particular to concentrated machine of multistage spiral-flow type.
Background
The thickener is widely applied to the treatment of slime, waste water and waste residue in the departments of metallurgy, mine, coal, chemical industry, building materials, environmental protection and the like, and has important significance for improving the backwater utilization rate and the underflow conveying concentration and protecting the environment. Thickeners are generally classified into three major categories, i.e., general thickeners, inclined plate thickeners, and high-efficiency thickeners.
The common thickener (commonly called rake thickener) is the most used thickener in the current concentrating plant, and is divided into a central transmission type (small diameter) and a peripheral transmission type (large diameter) according to the transmission mode. The thickener has simple structure, easy management and reliable production. However, because of its large diameter, it occupies a large area, and has large investment in capital construction, low production capacity per unit area, and low concentration efficiency.
The inclined plate (tube) type thickener is characterized by that on the upper portion of cylinder pool of general thickener, along the circumferential direction several inclined plates (tubes) are mounted, and said inclined plates (tubes) are inclined towards the centre of thickener, and their included angle with horizontal is about 60 deg. The measures accelerate the separation of ore particles, strengthen the separation and sedimentation process and improve the concentration efficiency. Compared with a common thickener, the production capacity of the thickener is improved by about 3 times, and the thickener greatly reduces the settling area due to the improvement of the efficiency, and is more suitable for the concentration and dehydration of fine-grained concentrate and tailings. However, the inclined plate is easy to fall off, deform and age due to its complicated structure, and is troublesome to maintain and operate.
High efficiency thickeners, which have been the ones that have been created and successfully used later, have a special flocculant addition mechanism in addition to the inclined plates in the round basin. In fact, the diameter of the dewatering equipment can be reduced to l/3-1/2 of a common thickener, the occupied area is only 1/9-1/4 of the common thickener, the unit area processing capacity is increased by dozens of times, and the dewatering equipment is a novel thickener which is increasingly widely applied; however, because the fine particles are not settled thoroughly and the content of suspended matters in the effluent is still more, the quality of the circulating water is difficult to better meet the production requirement, and as the former two thickeners, the transmission mechanical equipment and a large number of inclined plates with complex structures all increase the difficulty for maintenance and use.
