Description
Technical field
The present invention relates to a kind of seed precipitation tank to carry material device, more particularly to a kind of low-pressure air dosage seed precipitation tank carries material dress
Put, material is carried suitable for aluminum oxide industry seed precipitation tank, seed precipitation tank extraction pipe compressed air dosage can be significantly reduced, it is empty to reduce compression
The energy consumption of gas consumption, reduces and substitutes into kind of a carbon dioxide quantity for sub-material slurry by compressed air.
Background technology
At this stage, the seeded precipitation process of alumina industry uses more seed precipitation tank cascades, and in groove top portion, slurry passes through
Chute enters groove body, and after agitated mixing, slurry enters extraction pipe from trench bottom extraction pipe lower ending opening, flows up, by carrying
Expects pipe upper end opening flows out seed precipitation tank.
Traditional extraction pipe is integrally fixed at seed precipitation tank close to one of cell wall position or two vertical steel as shown in Figure 1
Manage, 0.5~1 meter or so of diameter, below generally two meters away from trough floor of bottom, make 45 degree of diagonal cut joint forms, opening direction is general
It is directed toward the center of groove body.Extraction pipe upper outlet is opened wide, and positioned at groove top portion and is higher than liquid level certain distance, through cell wall after with it is outer
Portion's chute connection.The compressed air hose that extraction pipe is set is the thinner steel pipe of a diameter, enters extraction pipe from extraction pipe top
Inside, 2 meters away from extraction pipe lower end or so of lower end.
The slurry of seed precipitation tank is solidliquid mixture, containing substantial amounts of aluminum hydroxide particles, although slurry is stirred through seed precipitation tank
Device mixes, but the concentration of solid particles of seed precipitation tank top and bottom slurry is not quite identical, and the concentration of solid particles of bottom is high
In top.Slurry in extraction pipe is all from seed precipitation tank bottom, therefore the density of slurry is greater than groove body in extraction pipe
Slurry averag density, the height of extraction pipe liquid level are less than the height of groove body liquid level.
When seed precipitation tank is fed, liquid level is gradually increasing, and slurry communication in extraction pipe and groove, liquid level is all rising, but extraction pipe
The height of liquid level is consistently lower than groove and puies forward slurry level, and liquid level difference reaches more than 1 meter.Go out when the height of groove body slurry reaches extraction pipe
During open height, discharge nozzle can not also discharge, it is therefore necessary to compressed air is passed through in extraction pipe, makes the normal slurry in extraction pipe
Density reduces, and extraction pipe liquid level can rise therewith, after extraction pipe slurry averag density is less than or equal to slurry averag density in groove,
Slurry can be exported from extraction pipe and discharged.In order to ensure that slurry continuously outflows, compressed air can continue to be admitted to larger flow
In extraction pipe.But compressed air can consume more electric energy, and carbon dioxide is substituted into slurry, produce carbonate and influence to decompose effect
Rate.
The content of the invention
In order to solve the above technical problem, the present invention provides a kind of low-pressure air dosage seed precipitation tank to put forward material device, purpose
It is seed precipitation tank agitating device to the horizontal circumferential flow of slurry generation, utilizes the strength of the circumferential flowing of slurry, promote extraction pipe material
Slurry discharging, can substantially reduce compressed air dosage, realize pollution energy-saving and that reduction carbon dioxide is to slurry.
To achieve these goals, the present invention is realized in：
Low-pressure air dosage seed precipitation tank carries material device, is that the extraction pipe bottom in seed precipitation tank groove body sets a babinet,
Extraction pipe is located at casing top, and the fluoran stream surface of babinet is equipped with opening.
Roof box and extraction pipe sealing welding.
Box bottom tilts, and meets stream side and is highly less than offside.
Box width is more than extraction pipe diameter.
It is open as rectangle or approximate rectangular.
Opening is located at the lower part of fluoran stream surface siding.
45 degree of diagonal cut joints are made in extraction pipe bottom, and opening direction is directed toward fluoran stream surface tank wall.
Advantages of the present invention effect：Present invention increase babinet and inclined floor structure, using the impact force of slurry liquid stream, when
When slurry rushes at box opening, due to tank floor angle of inclination, liquid stream is set to accelerate to flow into box house, liquid flow impact power makes case
The fluid pressure rise of internal portion, babinet and extraction pipe are enclosed constructions, and extraction pipe pressure also increases, and makes on extraction pipe liquid level
Rise.Therefore using a small amount of or without using compressed air, so that it may so that slurry is discharged from extraction pipe upper end, realize reduction even
Without using the purpose of compressed air.So as to reduce the energy consumption of compressed air consumption, the carbon dioxide quantity into slurry is reduced.

Embodiment
The embodiment of the present invention combination attached drawing is described in detail in below, but the protection domain invented is from embodiment institute
Limit.
As shown in Figures 2 and 3, low-pressure air dosage seed precipitation tank is carried in material device, including seed precipitation tank groove body, seed precipitation tank groove body
Extraction pipe, 2 bottom of extraction pipe set a babinet 3, extraction pipe 2 from roof box 4 enter babinet 3 inside, babinet 3 meeting stream
Plate of facing the wall and meditating is equipped with an opening 6.
Roof box 4 and 2 sealing welding of extraction pipe.
Box bottom 5 tilts, and meets stream side and is highly less than offside.
3 width of babinet is more than extraction pipe diameter.
Opening 6 is rectangle or approximate rectangular.
Opening 6 is located at the lower part of fluoran stream surface siding.
45 degree of diagonal cut joints are made in extraction pipe bottom, and opening direction is directed toward fluoran stream surface tank wall.
The operation principle of the present invention：
Using the impact force of slurry liquid stream, when slurry rushes at box opening, due to tank floor angle of inclination, make liquid stream
Accelerate to flow into box house, liquid flow impact power raises box house fluid pressure, and babinet and extraction pipe are closed communications, carry material
Pipe pressure also increases, and extraction pipe liquid level is increased.Therefore using a small amount of or without using compressed air, slurry can be from carrying
Expects pipe upper end is discharged, and realizes the purpose for reducing and not using compressed air even.
