Description
Technical field
The invention belongs to technical field of alumina production, relate generally to a kind of collocation method of red-mud settlement and separation washing procedure, be particularly useful for Bayer process alumina producer and be separated and wash the technique all adopting same size deep-cone settling groove.
Background technology
In Bayer process alumina producer production process, red-mud settlement and separation washing procedure common equipment is deep-cone settling groove, the subsider of appropriate size is selected according to red mud amount and related experiment report, because this device diameters is comparatively large, red-mud settlement and separation washing procedure floor space is also larger.Same size subsider is selected in current separation and washing usually, if one is separated and washs public affairs jointly for subsequent use for subsider.The collocation method that this kind of technique adopts usually has following two kinds: a kind ofly configure for " band shape ", namely all subsider central points are arranged point-blank, form a line, in subsider opening for feed direction, the one-sided pipe rack that arranges is for stringing, lower than subsider opening for feed about 1 meter of by subsider cell wall and pipe support pillar setting operation steel platform, platform edges need meet operating space apart from cell body edge closest approach distance, the corresponding distance about 8 meters of usual Ф 20 meters of subsiders, this distance increases along with the increase of subsider diameter.Establish cofferdam in red-mud settlement and separation washing zone surrounding, cofferdam inner compartment is not only thin but also long, is not suitable for the alumina producer that the terrace discrepancy in elevation is larger; Another kind is " eight pies " configuration, namely all subsiders in two separate ranks and configure side by side, in the middle of two row's subsiders, a pipe rack is set for stringing, subsider opening for feed is arranged on pipe support direction, lower than subsider opening for feed about 1 meter of by both sides subsider cell wall and intervalve post setting setting operation steel platform, two row subsider closest approach distances need meet operating space, and the corresponding distance about 15 meters of usual Ф 20 meters of subsiders, this distance increases along with the increase of subsider diameter.Red-mud settlement and separation washing zone surrounding establishes cofferdam, and cofferdam inner compartment is generally rectangle, and because two row subsiders configure side by side, two row subsider width between centerss are comparatively large, and red-mud settlement and separation washing zone floor space is also larger.
It is large to there is floor space in above two kinds of collocation methods, and configuration underaction, invests high problem.
Summary of the invention
The present invention is exactly the collocation method of a kind of red-mud settlement and separation washing procedure provided to solve the problem, and its objective is and realizes reducing red-mud settlement and separation washing procedure floor space, reduce investment outlay.
For reaching above-mentioned purpose, the present invention is achieved in that
A collocation method for red-mud settlement and separation washing procedure, all subsiders are in two separate ranks and be crisscross arranged; Arrange a pipe rack for stringing in the middle of two row subsiders, pipe support lower channel is as red-mud settlement and separation washing zone inspection gallery; Lower than subsider opening for feed 0.8-1.2 rice by both sides subsider cell wall and intervalve post setting setting operation steel platform, red-mud settlement and separation washing zone surrounding establishes cofferdam.
Described subsider in two separate ranks and be crisscross arranged, makes two row subsider central points be positioned in the flex point of " W ".
In the middle of described two row subsiders, a pipe rack is set for stringing, pipe support lower channel as red-mud settlement and separation washing zone inspection gallery, guaranteeing by middle-size and small-size tool car of pipe support lowest layer absolute altitude and pipe support width.
Described subsider opening for feed is arranged on pipe support direction.
Be about 0.8-1.2 rice lower than subsider opening for feed by both sides subsider cell wall and intervalve post setting setting operation steel platform, this distance increases along with the increase of subsider diameter.
Described red-mud settlement and separation washing zone surrounding establishes cofferdam, and ramp is established at two ends, cofferdam, is convenient to red-mud settlement and separation washing zone inspection gallery and enters car.
Described cofferdam inner compartment is parallelogram.
Described cofferdam inner compartment is trapezoidal.
Lower than subsider opening for feed about 1 meter of by both sides subsider cell wall and intervalve post setting setting operation steel platform.
Advantage of the present invention and effect are: the technical program flexible configuration, and floor space is little, reduces investment outlay.
Accompanying drawing explanation
Fig. 1 is the layout diagram of the collocation method of a kind of red-mud settlement and separation washing procedure of the present invention;
Fig. 2 is service platform floor map;
In accompanying drawing: 1, subsider; 2, pipe support; 3, cofferdam; 4, subsider opening for feed; 5, steel platform is operated; 6, ramp A; 7, ramp B.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail, but protection scope of the present invention not limit by embodiment.Subsider quantity of the present invention is not limited only to the form disclosed in embodiment, and as subsider can be set to odd number, its cofferdam shape should be trapezoidal mutually.
As shown in Figure 1 and Figure 2, all subsiders 1 in two separate ranks and be crisscross arranged; Arrange a pipe rack 2 for stringing in the middle of two row subsiders 1, pipe support 2 lower channel is as red-mud settlement and separation washing zone inspection gallery; Lower than subsider opening for feed 0.8-1.2 rice by both sides subsider 1 cell wall and pipe support 2 pillar setting operation steel platform 5, red-mud settlement and separation washing zone surrounding establishes cofferdam 3.
Described subsider 1 in two separate ranks and be crisscross arranged, makes two row subsider central points be positioned in the flex point of " W ".
In the middle of described two row subsiders 1, a pipe rack 2 is set for stringing, pipe support lower channel as red-mud settlement and separation washing zone inspection gallery, guaranteeing by middle-size and small-size tool car of pipe support 2 lowest layer absolute altitude and pipe support width.
Described subsider opening for feed 4 is arranged on pipe support 2 direction.
0.8-1.2 rice is being about by both sides subsider 1 cell wall and pipe support 2 pillar setting operation steel platform 5 lower than subsider opening for feed, platform edges need meet operating space apart from cell body edge closest approach distance, the distance about 8 meters that usual Ф 20 meters of subsiders are corresponding, this distance increases along with the increase of subsider diameter.
