Description
Technical field
The present invention relates to the fall cyclone bar shaped unit integrated technologies such as a kind of overflow fineness appreciation one one liter of nothing of fall, low in genus
Grade collophane and other mineral grind gradings be theoretical and technology.
Technical background
The fall cyclone annular units such as annular unit Φ 660mm are all used at the cyclone unit that grinding classification system is conventional
Pulp-inlet pipe 10 is arranged on unit bottom, and slurry is entered slurry dispenser 3 by Pulp pump pump pressure through pulp-inlet pipe 10, is assigned to 4 for 2
The fall cyclones 1 such as (4 operations 2 are standby) Φ 660mm, hydrocyclone sand is drained into sand setting case 7, through sand setting channel nozzle 11 row
Enter to sand setting sampling cabinet 12, return primary grinding machine through sand setting outlet and regrind.Overflow product enters overflow through outer overflow pipe 2
Case 6, then through spill box overflow discharge connection 14, enter overflow sampling cabinet 13, it is discharged to two-stage nitration through overflow sampling cabinet discharge pipe 16
After Product mix is arranged with two-stage nitration mill in ore mill ore discharge pump pond, squeeze into the fall cyclone annular units such as Φ 500mm with Pulp pump.
The fall cyclone annular unit such as Φ 500mm enters pipe 10 and is arranged on unit bottom, and slurry is pumped through entering by Pulp pump
Slurry pipe 10 enters slurry dispenser 6, is assigned to 6 for fall cyclones 3 such as 3 (6 operations 3 are standby) Φ 500mm, and cyclone sinks
Sand is drained into sand setting case 1, is drained into sand setting sampling groove 8 through sand setting channel nozzle, returns secondary grinding machine again through sand setting outlet
Mill.Overflow product enters spill box 4 through outer overflow pipe 2, then enters overflow sampling cabinet 9 through spill box overflow discharge connection,
Follow-up flotation operation agitator is entered through overflow sampling cabinet discharge pipe.
There are serious point of slurry inequality, No. 6 hydrocyclone sands in the fall cyclone annular unit such as background (existing) technology Φ 660mm
Drawing dry tie rod, No. 3 hydrocyclone sands to have loose bowels, the former overflow is run thick and the latter is then thin and dilute, and its result is as shown in table 1.Φ
The fall cyclone annular unit such as 500mm is also to there is a point slurry inequality, and its result is as shown in table 2.
Two grooves, in addition to point slurry granularity inequality, owing to sand setting and overflow stream are in changeless position, are not stopped by annular unit
Impact, single-point abrasion especially severe, cause whole casing short-term to have to because of single-point spillage a complete set of replacing, cause greatly
Waste.
Being open trough additionally, due to annular unit discharging opening, ore pulp fog is soaring, environmental pollution especially severe.For example
Such as alumina producer, grind grading runs under the conditions of high temperature 95 DEG C and high-alkali 200 gram liters, and uncovered two grooves cannot ensure safe life
Produce, personal safety accident can occur at any time.
Summary of the invention:
Too high and the closed circuit Φ of two-stage nitration for fall cyclone overflow fineness appreciations such as annular one section of closed circuit Φ 660mm of unit
The fall cyclone overflow fineness such as 500mm appreciates too low;The fall cyclone annular unit such as Φ 660mm enters slurry from unit bottom to be caused point
Slurry granularity is uneven, opens one sand setting of three cyclones and draws dry tie rod, and overflow is run slightly, a sand setting is had loose bowels, and overflow is the thinnest but also dilute
Deng three big problems.The present invention provides the fall cyclone bar shaped unit integrated technologies such as a kind of overflow fineness appreciation one one liter of nothing of fall.Tool
Body say be existing two section of two closed circuit overflow fineness is appreciated " one high and one low "+wait fall cyclone+annular unit integrated technology, transform
