Description
Technical field
The utility model belongs to preparation equipment technical field, integrated more particularly to a kind of coal slime flotation use of flotation concentrate
Defoaming device.
Background technique
With the development of mining mechanization and national economy, the demand and yield of coal increase year by year, still, raw coal
Quality but declining, good coal resources are fewer and fewer, and coalcutter is adopted unlike artificial big gun, coalcutter without selectivity,
No matter how down-hole coal bed quality cuts down as raw coal, and the fine coal content in raw coal is higher and higher, some coals
Mine is more than 30%, wherein needing after coal mining containing the non-coal mine object for being largely easy to argillization in order to make full use of coal resources
Coal separation processing is carried out, to remove the noncombustibles such as spoil, reduces former pit ash.
Sorting for Bed for Fine Coal, widely used, maximally efficient method are flotation, and flotation is using foaming agent in mine
A large amount of bubble is generated in slurry, there is hydrophobic coal grain to attach on bubble on surface, and with bubble floating to froth zone, then use
Bubbler is scraped to scrape foam to concentrate slot, and the particle that surface hydrophobic is poor, such as particulate spoil, it is left in ore pulp, with mine
Slurry flow to flotation machine tail end as tail coal, to realize the sorting of particulate raw coal.
Flotation column is widely used in coal slime flotation, flyash flotation, and flotation pulp, air and medicament are in microvesicle generators
It is sufficiently mixed under effect, after mineralising, selects concentrate using the effect of bubble and medicament, flotation concentrate carries a large amount of microvesicle and enters
Concentrate collecting tank is simultaneously flow in concentrate collecting vessel certainly；When entering to wash one of parameters such as raw ore amount, washing water consumption, hygienic water
It changes, all the concentration of flotation pulp can be made instantaneously to change, when floating agent has little time adjustment, often will appear floating
Concentrate selection carries a large amount of macrofoam and enters concentrate collecting tank and flow in concentrate collecting vessel certainly, these microvesicles and air pocket are in essence
It is difficult to be voluntarily crushed in mine collecting vessel, is partially bonded together the bubble for becoming bigger, causes concentrate bucket bubble cumulative, very
To overflow, make troubles to postorder processing: pulp conveying pump is also easy to produce cavitation, serious wear；The filter press pan feeding time is long,
The problems such as filter efficiency is low, and filter cake moisture is big.
Bubble is the indispensable part of coal slime flotation, it is the medium of slime separation, and is the delivery work of valuable mineral
Tool.But the presence of bubble but brings many difficulties to the subsequent dewatering operation of floatation clean coal.Floatation clean coal generally uses
The method of pressure filtration or vacuum filter separates coal grain and water, due to containing a large amount of grade and micron order in floatation clean coal
Bubble, cause the pressure difference in filter medium two sides impacted, filter cake is empty and thin, and dehydration efficiency is low, and power consumption is big, and final essence
The moisture content of coal is high, can not meet requirement of the user for moisture content index.Therefore, floatation clean coal is before entering dewatering operation
It is defoamed, the bubble removal in floatation clean coal ore pulp is fallen.The defoaming mode of current use is generally single disappear
Bubble is defoamed, such as artificial defoaming, water spray defoaming, defoaming agent defoaming, and traditional single formula defoaming mode, which has, to be had a single function,
The defects of defoaming capacity is limited, and application range is small；One kind be provided thus have a wide range of application, defoaming effect it is good, can be according to bubble
The diversification of big how many adjustment defoaming modes integrates defoaming device.
