Description
Technical field
The present invention relates to a kind of slurry concentrating device, more precisely, being a kind of medicament adding device of high-efficiency concentrator.
Background technology
Whether the production that the quality of slurry concentrating treatment directly affects Zhe Xuan factories can be smoothed out, and be to evaluate a Zuo Xuan factories
One of technology and the most important factor of managerial skills, the quality influence of slurry concentrating treatment effect even determine the warp in mining area
Ji benefit and social benefit.Pulp thickening system is responsible for the effect of recovery process water, and its final purpose is to meet environmental requirement
Realize closed water circuit.
General high efficiency thickener improves material sinking speed, whether timely, the flocculation of flocculant addition by flocculant
How much the consumption of agent is all related to the concentration degree and clarifying speed of thickener overflow water.Additionally, rationally flocculant mixes with ore pulp
It is more abundant, medicament utilization rate is higher, medicine consumption it is smaller, the action effect of medicament is better.Traditional flocculant adding method is first logical
Cross manual method (utilize a kind of stock, above there is scale to visit the thickness of bed in thickener) elicite it is material bed in concentrator
Thickness, rule of thumb judges that addition flocculating agent and flocculation dosage increase or reduces.When pulp dewatering is processed, technical staff
Generally according to concentration distribution material bed in concentration basin, the method that pan feeding pipeline directly adds flocculant before thickener is taken,
To accelerate particle agglomeration precipitation purpose.The number of flocculant addition directly affects the effect of settling of black water.
In the prior art, Automatic Dosing mode more advanced both at home and abroad is disclosed in Chinese patent literature CN1958116A
" automatic adding flocculant is united and its method ", its concentration and flow that black water is detected according to densimeter and flowmeter, by work
Control machine controlling pump adds flocculant, sensor to detect the concentration of overflow water, then judges overflow water concentration by industrial computer, decides whether
Start pump to dosing in concentration basin.
Traditional flocculant adding method needs enough field experiences, but is added without advanced detecting system and medicament
System, it is unstable to easily cause overflow back water index, and with hysteresis quality；In addition do not account for how improving pharmacy effect effect
Really.
On " automatic adding flocculant is united and its method ", the system and method disclosed in patent document CN1958116A
Save flocculant usage, improve clean coal yield, but there is problems with,：(1) system imperfection, only provides a kind of automatic
How adding method thereof, add medicament and which kind of means dispersions taken without explanation, to reach depth clarification black water and section
Save the purpose of medicament；(2) using thickener overflow concentration as unique performance assessment criteria, it is not inconsistent with actual conditions, in coal slime water depth
In clarification, engineers and technicians would generally be concerned about two problems, first be the concentration distribution situation of bed in thickener, next to that
Overflow water concentration, bed change in thickener is ignored if being only concerned overflow water concentration, medicament is added simply, it will cause dense
Contracting machine " pressure rake " phenomenon (namely due in thickener bed it is too thick, concentration is too big, causes the rake stop motion of circular motion,
And cause the material cannot be from the phenomenon of thickener underflow mouthful discharge), the normal production of coal preparation plant will be had a strong impact on.
