Abstract
The invention provides and a kind ofly improve the dense device of phosphorus mine tailing, it is characterized in that, with the central tube of concentrator for the center of circle, concentrator nominal length is radius, setting up a diameter is the spray header of 30-40mm, arrange the annular spray tank that a volume is 1.5 cubic metres outside the central tube of concentrator, water inlet place of annular spray tank is connected with accident pool through flexible pipe, and annular spray tank is connected with spray header through spray pump.Concentrator is also provided with a centrifugal pump of horizontal axis, this horizontal centrifugal pump inlet sprays tank with annular and is connected, and outlet is connected with spray header.Spray header is also provided with multiple nozzle, and injector spacing is 60mm, and nozzle diameter is 0.3mm.This equipment significantly reduces operating cost, can large-scale popularization use in the art.
Description
Technical field
The present invention relates to a kind of dense device, be specially the dense device improving phosphorus mine tailing, belong to field of chemical equipment.
Background technology
Chemical inc of state, Hubei six produces 80kt concentrate ore-dressing plant per year, because processing mine tailing 35 ~ 400,000 tons every year, goes into operation so far from October 1st, 2012, and tailings glass system is the bottleneck that stagnant about whole ore-dressing plant is produced all the time, due to flotation raw ore P
2o
5the decline of content, the rising of content of MgO, in Floating Production Process, consume more flotation agent, flotation tailing exists with form of foam, is constantly enriched in thickening pond surface, and make a big impact to mine tailing sedimentation, major influence factors is as follows:
1, the flowing of foam baffle overflow water is blocked in the increase of foam enrichment amount, occurs " running muddy ", finally affects concentrate product quality.
2, due to the increase of foam enrichment amount, nature antifoaming speed declines, part foam is delivered to next process after mixing with certain density ore pulp with gravitational settling: ceramic filter filters, lower with the Tailings Slurry concentration of form of foam existence by analysis, the flotation agent do not digested and not assimilated in floatation process adheres to organic matter form and spreads upon ceramic wafer surface, very easily block ceramic filtering plate micropore, cause intensity filter to decline, serious service life of reducing ceramic filtering plate.
Summary of the invention
The object of the present invention is to provide a kind of novel concentrator, eliminate the foam of enrichment in phosphorus mine tailing floatation process.Concrete technology is as follows:
A kind of dense device improving phosphorus mine tailing, with the central tube of concentrator for the center of circle, concentrator nominal length is radius, setting up a diameter is the spray header of 30-40mm, the annular spray tank that a volume is 1.5 cubic metres is set outside the central tube of concentrator, water inlet place of annular spray tank is connected with accident pool through flexible pipe, and annular water tank is connected with spray header through spray pump.
Be provided with water circulating pump in described accident pool, this water circulating pump is connected with flexible pipe.
Described concentrator is also provided with a centrifugal pump of horizontal axis, this horizontal centrifugal pump inlet sprays tank with annular and is connected, and outlet is connected with spray header.
Described spray header is also provided with multiple nozzle, and injector spacing is 60mm, and nozzle diameter is 0.3mm.
Also be equipped with filling pipe in described annular spray tank, this filling pipe is connected with flexible pipe.
The flow of described centrifugal pump of horizontal axis be 30 cubic metres per hour, lift is 20m, and power is 3kw, and rotating speed is 2900r/min.
The running speed of described concentrator is 20min/ circle.
Adopt technical scheme of the present invention to have following beneficial effect: before transformation, due to the ceramic filtering plate of the beneficiation reagent blocking ceramic filter that foam is carried secretly, cause filter plate serious curtailment in service life.Overlap through adding up the annual accumulative ceramic filtering plate 8 that consumes in 2013, a set of filter plate most 4 months long lives, the shortest has only used 2 months.
Within improved 2014, the annual ceramic filtering plate 2 that only consumes overlaps, and saving ceramic filtering plate 6 of comparing overlaps, and calculates, save ceramic filtering plate buying expenses 2304000 yuan the whole year altogether by 384000 yuan/cover; The raising of filter efficiency simultaneously makes the filter capacity of unit are increase, make the year of ceramic filter total driving rate from 16.11% in 2013 be reduced to 2014 9.28% (there are three filters in company, generally " one open two standby ", sometimes " two open one standby "), operating cost, installation and maintenance cost, regenerative agent cost meter 51840 yuan that contrast is saved; Namely this invention can every year for company brings the benefit of about 2,360,000 yuan.
