The horizontal scraper is used for beneficiation and is provided with a supporting structure, wherein the supporting structure comprises a support and a fixed disk; the two ends of the support are fixed at the outer edge of an ore concentrate collecting groove, the fixed disk is arranged in the middle of the support, a motor is fixed on the support, a rotation disk is hung on the fixed disk by a thrust bearing, the inner contact surfaces of the rotation disk and the fixed disk are sealed by a pump sealing element, and a border gear of the rotation disk is connected with a gear of the motor and is connected with a water inlet pipe hole on the fixed disk; and the scraper is fixed below the rotation disk, and a spray water pipe is fixed behind the scraper. The horizontal scraper can reduce the loss of useful constituents of ore concentrate, improve the recovery rate of the ore concentrate and control the quality of the ore concentrate, thereby acquiring a higher ore concentrate grade and improving the concentration ratio; the impact of lower grade foams at a lower layer on the ore concentrate grade is eliminated when in the discharging along the border of a cylinder body of the flotation column; and level grade surfaces at foam layers are arranged sequentially in strict accordance with altitude differences.
Description
Technical field
The utility model relates to the flotation column in a kind of preparation equipment.
Background technology
Known flotation column is mineral manufacture field a kind of floatation equipment commonly used, is widely used in the separation operation of non-ferrous metal, ferrous metal, rare precious metal and coal, chemical industry mineral etc., and demonstrates outstanding superiority.The kind of flotation column is numerous, KYZ flotation column (the surplus dragon boat that Canadian CPT flotation column and Bei Kuangyuan are typically arranged, the automatic Detection ﹠ Controling of flotation column froth bed thickness, " the outstanding Master's thesis of Kunming University of Science and Technology " in March, 2008, middle National IP Network), the FCMC flotation column of China Mining University (thanks to the Guangyuan, " mineral dressing ", publishing house of China Mining University, August calendar year 2001).
These flotation columns comprise cylindrical shell and concentrate feeder, have similar working principle, and flotation area and foam enriched layer are all arranged.Realize bubble mineralization in flotation area, and realize the secondary enrichment at froth bed.Make froth bed present grade trend of rising from bottom to top under the effect of shower water, the grade of the froth bed the superiors is the highest, below each layer reduce one by one.
Along with the continuous increase of froth bed thickness, when the froth bed of the superiors exceeded the flotation column cylindrical shell, mineralized froth began to overflow and enters the concentrate feeder.When the froth bed of the superiors overflows, its pressure in inboard, flotation column cylindrical shell edge reduces, and because the viscosity pulling force of the froth bed of the superiors, the froth bed of lower floor enters the concentrate feeder in cylindrical shell edge come-up and under the froth bed of the superiors related, concentrate yield increase, grade are reduced, ratio of concentration descends, and beneficiating efficiency reduces.
In addition, mineral laden bubble will enter concentrate hopper must be to flotation column cylindrical shell edge transitions, and the mineral laden bubble that is positioned at the center produces that radial displacement needs that thickness constantly accumulates, just can take place during projecting froth bed.This must increase the time of staying of mineral laden bubble on froth bed, under the flushing action of shower water, froth bed etc. the product plane be gradually to recessed sphere.This concentrate product that just causes a part to float progressively is flushed to below the froth bed by shower water in the process that stops, and finally enters mine tailing, causes the rate of recovery of floatation process to reduce, and the mineral resources utilization rate is descended.
Summary of the invention
Discharge the reduction of mode grade in order to overcome the flotation column concentrate, ratio of concentration descends, the defective that beneficiating efficiency reduces, and the utility model provides a kind of flotation column horizontal scraper plate, and this flotation column horizontal scraper plate can improve the grade of flotation concentrate, improves ratio of concentration.
The technical solution of the utility model is: this flotation column horizontal scraper plate is provided with supporting construction, drive mechanism and work structuring; Supporting construction comprises support and fixed disk, and the two ends of support are fixed on concentrate feeder outer, and fixed disk is installed in the centre of support, and buoy passes from carriage center; Drive mechanism comprises motor and rolling disc, motor is fixed on the support, rolling disc is lifted on the fixed disk by thrust bearing, the interior contact-making surface of rolling disc and fixed disk seals with seal with pump, the edge gear of rolling disc is connected with motor gear, rolling disc inside is provided with water channel and spray header joins, and link to each other with water inlet pipe mouth on the fixed disk; Work structuring comprises scraper plate and spray header, and scraper plate is fixed on rolling disc below, the knife face of scraper plate forward, spray header is fixed on the scraper plate back and rotates with scraper plate.
Described scraper plate section is " right angle " shape, and the flat shape of scraper plate is a strip, or arc.Scraper plate is active collection top layer concentrate when rotating, and water spray increases along with the increase of the radius of gyration, guarantees the even of shower water.
Advantage of the present utility model: along with the rotation of scraper plate, in time scrape the froth concentrate that has floated, thereby reduce concentrate, reduce the loss of useful constituent in the concentrate, can effectively improve the rate of recovery of concentrate in the time of the accumulation and the stop of froth bed; Scraper plate only scrapes the highest concentrate of top layer grade, can effectively control the quality of concentrate, thereby obtains higher concentrate grade, increases ratio of concentration; The influence to concentrate grade of the relatively poor foam of lower floor's grade when having eliminated along flotation column cylindrical shell edge ore discharge; And make froth bed etc. the product plane be arranged in order in strict accordance with the discrepancy in elevation, make the control of floatation process more accurate.
