Abstract
The utility model relates to a floatation concentrate collecting device of a large-diameter flotation column and belongs to the field of flotation equipment. The floatation concentrate collecting device of the large-diameter flotation column is composed of an inner ring groove, dividing grooves, an outer ring groove and screens. The inner ring groove is connected with the dividing grooves. The dividing grooves are fixed to the inner side of an overflow weir of a column body of the flotation column. The outer ring groove is fixed to the outer side of the overflow weir of the column body of the flotation column. The screens are evenly arranged in the outer ring groove. The inner ring groove is a V-type ring groove arranged in the middle of the column body. The floatation concentrate collecting device of the large-diameter flotation column is mainly used for collecting floatation concentrate in the middle of the column body of the flotation column, decreasing the thickness of a floatation concentrate layer in the middle of the column body, and improving the discharge efficiency and recovery efficiency of the floatation concentrate. The dividing grooves are V-type conveying tanks connecting the inner ring groove with the overflow weir of the column body. The outer ring groove is a ship-form collecting groove in the outer side of the overflow weir of the column body of the flotation column. The screens are woven meshes evenly distributed on the inner side of the outer ring groove. The floatation concentrate collecting device of the large-diameter flotation column has the advantages that the recovery efficiency of the floatation concentrate is high, and the defoaming effect of the floatation concentrate is good.
Description
Affiliated technical field
The utility model relates to a kind of gathering-device of major diameter flotation column flotation concentrate, belongs to floatation equipment field.
Background technology
Flotation column is widely used in the nonmetal and non-ferrous metals such as floating tail-coal, flyash, graphite.Along with global resources are increasingly poor, the requirement that existing resource is made full use of is more and more higher, requires more and more higher to the rate of recovery of flotation concentrate.
The gathering-device of the flotation column flotation concentrate using is at present: arrange " ship " type feeder in flotation column cylinder downflow weir outside, flotation concentrate flow to feeder certainly along cylinder downflow weir.This gathering-device is less than at column diameter on the flotation column of φ 4500mm and is widely used, effect is better, apply but be greater than at column diameter on the flotation column of φ 4500mm, have the following disadvantages: the flotation concentrate at cylinder middle part is far away apart from cylinder downflow weir, the relative downflow weir of flotation concentrate at middle part exceeds certain distance, could overflow from flowing to downflow weir to periphery, due to middle part flotation concentrate bed thickness, flotation concentrate discharge efficiency is low, stoped the overflow of a part of flotation concentrate in cylinder middle part, the rate of recovery of flotation concentrate is low simultaneously.Especially when major diameter flotation column flotation graphite and non-ferrous metal fine, the flotation concentrate at cylinder middle part can not be discharged in time, has a strong impact on the rate of recovery of flotation concentrate; The bubble of flotation concentrate is more in addition, and to postorder, processing makes troubles, and pollutes cylinder surrounding environment when serious.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of gathering-device that improves the flotation concentrate rate of recovery, major diameter flotation column flotation concentrate that concentrate defoaming effect is good is provided.
The gathering-device of a kind of major diameter flotation column flotation concentrate described in the utility model, is made up of inner groove, splitter box, outer groove, screen cloth; Inner groove connects with splitter box, and splitter box is fixed on flotation column cylinder downflow weir inner side, and outer groove is fixed on flotation column cylinder downflow weir outside, and screen cloth is evenly arranged in outer groove.
Described inner groove is arranged " V " type annular groove, Main Function at cylinder middle part: collect the flotation concentrate at flotation column cylinder middle part, reduced the thickness of cylinder middle part flotation concentrate layer, improved flotation concentrate discharge efficiency and the rate of recovery.
Described splitter box is multiple " V " type feeding groove that connects inner groove and cylinder downflow weir, its Main Function: the flotation concentrate that inner groove is collected is delivered in outer groove, extend the length of downflow weir simultaneously, further improved flotation concentrate discharge efficiency and the rate of recovery.
Described outer groove is arranged " ship " type feeder, its Main Function: collect all flotation concentrates, and discharge by flotation concentrate discharge gate in flotation column cylinder downflow weir outside.
Described screen cloth is the several establishment nets that are evenly arranged in outer groove inner side, its Main Function: flotation concentrate slides to screen cloth under inclined-plane, outer groove bottom accelerates, with screen cloth collision, a part of flotation concentrate bubble breaking is stitched and is flow to discharge gate discharge by sieve with flotation concentrate liquid; Another part flotation concentrate bubble is adsorbed on screen cloth; through rinsing and dilute along the dirty shower water of screen cloth; because bubble surface film tension failure makes also to be stitched and flow to discharge gate discharge by sieve with flotation concentrate liquid after bubble breaking, flotation concentrate defoaming effect is good, has protected cylinder surrounding environment.
The beneficial effects of the utility model are: the flotation concentrate rate of recovery is high, flotation concentrate defoaming effect is good.
Brief description of the drawings
Fig. 1 is front view of the present utility model,
Fig. 2 is the top view of Fig. 1,
In figure: 1-inner groove, 2-splitter box, 3-outer groove, 4-screen cloth.
Detailed description of the invention
As shown in the figure: flotation concentrate layer is formed at cylinder top, the flotation concentrate overflow at middle part is to inner groove 1, all the other flotation concentrate overflows are to splitter box 2 and outer groove 3, the flotation concentrate that inner groove 1 and splitter box 2 are collected is from flowing in outer groove 3, the flotation concentrate flowing automatically in outer groove 3 glides and collides after froth breaking with screen cloth 4 through outer groove 3 inclined-planes, bottom acceleration, is stitched and is flow to discharge gate discharge by sieve.
