Abstract

The utility model provides an underflow pipeline of a concentrator. The underflow pipeline comprises four ore discharging openings which are uniformly distributed at the same periphery of the bottom of the concentrator, and a general pipeline for joining and connecting the four ore discharging openings into an underflow pump, wherein an extended line of the general pipeline is used for symmetrically and equally dividing the four ore discharging openings by the circle center of the periphery of the ore discharging openings. Two sections of arc-shaped pipelines are symmetrically distributed on the outer side of the periphery of the ore discharging openings along the extended line of the general pipeline; the two sections of arc-shaped pipelines and the periphery of the ore discharging openings are concentric; the two ore discharging openings on each side are connected to the corresponding arc-shaped pipelines along the diameter direction; an outlet is formed in each arc-shaped pipeline and in the middle position of the two ore discharging openings; the middle outlets of the two arc-shaped pipelines are connected with the two ends of one arc-shaped pipeline connected to the general pipeline respectively. According to the underflow pipeline of the concentrator, the line lengths from the parts for placing the four ore discharging openings to the pipeline of the underflow pump are same in a production process, so that pressures of all the ore discharging openings are same, and the bottom concentrations of the concentrator are same, thus the underflow pipeline of the concentrator has a good effect on stabilizing the work of the concentrator.

Description

The thickener underflow pipeline

Technical field

The utility model belongs to ore pulp pipeline field of configuration, particularly a kind of thickener underflow pipeline.

Background technology

Thickener is intermediate link very important in ore dressing plant, plays stable regulation front and back work flow and acts on normally, and along with the progressively expansion of selecting the factory rules and regulations mould, the model of thickener also constantly increases.Often thickener underflow was opened one or two gape and can be met flow in the past, and now a lot of thickener underflow gapes at least need there are four, so how to arrange that the underflow pipeline is extremely important.If the underflow line arrangement is unreasonable, will make thickener production go wrong, such as phenomenons such as underflow density is not up to standard, pressure rakes.

Tradition underflow pipeline arrangement form usually as shown in Figure 1, four drawholes are uniform in the thickener bottom, a drawhole 1 and No. two drawholes 2 converge to pipeline 5 No. one, No. three drawholes 3 and No. four drawholes 4 converge to 6, numbers pipelines 5 of No. two pipelines and feed total pipeline 7 to underflow pump 8(a-worker-a-backup together with No. two pipelines 6).This kind of arrangement form makes a drawhole 1 different apart from the distance of underflow pump 8 from No. two drawholes 2, No. three drawhole 3 is different apart from the distance of underflow pump 8 from No. four drawholes 4, during underflow pump 8 work, impeller has self-suction, make drawhole 1 and No. two drawholes 2, No. three drawholes 3 different with No. four drawhole 4 place's pressure, because having difference, two place's pressure make gape place, thickener bottom CONCENTRATION DISTRIBUTION inequality, cause local concentration excessive, have a negative impact to concentrated, to such an extent as to press rake.

Summary of the invention

The purpose of this utility model is to provide a kind of thickener underflow pipeline, by the reasonable Arrangement to the thickener underflow pipeline, solves thickener production and the problems such as similar underflow density is not up to standard, pressure rake occur.

The purpose of this utility model realizes by following technical proposals:

A kind of thickener underflow pipeline, be included in equally distributed four drawholes on the same circumference in thickener bottom, four drawholes are converged to the total pipeline that accesses underflow pump, and the center of circle of the extended line process drawhole place circumference of total pipeline is also carried out symmetry by four drawholes and is divided equally.Extended line in the outside of drawhole place circumference along total pipeline is arranged symmetrically with two sections arc pipelines, two sections arc pipelines are all concentric with drawhole place circumference, two drawholes of each side are connected on corresponding arc pipeline along the diametric(al) at place respectively, the upper centre position in two drawholes of each arc pipeline is provided with an outlet, and the central exit of two arc pipelines is connected with arc pipeline two ends that are connected on total pipeline respectively.

The described arc pipeline be connected with total pipeline is located at the inboard of the arc pipeline directly be connected with drawhole.
