Description
Technical field
The utility model is related to waste water or technical field of sewage, and in particular to a kind of recycling for bauxite sewage
Tank.
Background technology
China's bauxite resource is abundant, and reserves occupy the 4th, the world, are mainly distributed on Shanxi, Guizhou, Henan, Guangxi, Sichuan
With the ground such as Yunnan.The average grade of bauxite is：Al2O361.99%, SiO210.40%, mainly based on diaspore.
The alumina producer of 95% or more the country uses Bayer process production technology at present.Chemical formula is：Al2O3+ (1 or 3) H2O+2NaOH+aq
→2NaAl(OH)4The core of+aq, Bayer process production technology are the dissolution processes of bauxite ore pulp, due to ore alumina silica ratio compared with
It is low, thus cause China's process for making alumina complicated, production cost is high, while the aluminium spent acid contained in sewage is excessive, directly
Discharge not only results in environmental pollution, while will also result in the waste of resource, it is therefore desirable to the aluminium of the inside is extracted, due to
Contain higher Al in flyash2O3, content generally can reach 20%~40%, reaches as high as 50% or more, can replace bauxite
As a kind of good alumina resource, therefore the technology of extraction aluminium oxide is received more and more attention and is ground from flyash
Study carefully.The method of China's treated coal ash mainly has the acid-hatching of young eggs, alkali fusion.Wherein the acid-hatching of young eggs is more flexible relative to alkali fusion, and two
Secondary residue is less, and silicon and aluminium in flyash easy to implement, iron are completely separated, and become the heat of flyash extraction aluminium oxide research
Point field.But a large amount of liquid containing aluminic acid are generated in acidity extraction alumina process, if direct emission not only results in resource
Waste, can also cause environment prodigious destruction.
A kind of recycling profit of flyash acidity extraction aluminum oxide technology sewage as disclosed in Publication No. CN103936048B
With method, it is the sewage generated using the steel slag treated coal ash acidity extraction aluminium oxide being discharged in steelmaking process, recycles it
Middle aluminium oxide and iron oxide, and acid solution is consumed, the combined recovery for belonging to spent acid containing aluminium and solid waste utilizes technical field.
Steel slag is added in sewage with certain solid-liquid ratio by this method first；Operation temperature is 50-100 DEG C, reaction time 1-
3h；The hydrogen recycling generated in reaction, for providing heat source for reaction；It is separated by solid-liquid separation, joint removal of impurities, crystallization, calcines, obtain oxygen
Change aluminium and ferric oxide solid；The filter residue of separation of solid and liquid can be doped in steel slag, doping ratio 1-10:1 (steel slag：Filter
Slag), realization recycles.The utility model utilizes the steel slag treated coal ash acidity extraction aluminium oxide being discharged in steelmaking process
Technology sewage, the treatment of wastes with processes of wastes against one another realize the combined governance and resource reclaim of liquid solid refuse.
It needs to carry out crystallisation step when being separated by solid-liquid separation, crystallization needs to use crystallizing tank, the solid after general crystallization
Substance is from the bottom discharge of crystallizing tank, since the bottom of crystallizing tank is conical lower section, and be located at bottom discharge port nor
It is very big, some dead angles for being difficult to clear up are there is, are difficult to discharge after causing crystallization.
Utility model content
The utility model is intended to provide a kind of recycling can for bauxite sewage, to solve the discharging of prior art crystallizing tank
Difficult problem.
A kind of recycling can for bauxite sewage in this programme, including tank body, the inlet tube on tank body and go out
Material mouth, is equipped with blender in tank body, and the tank body includes bottom plate, capping and connecting bottom board and the wall of capping, it is described into
Liquid pipe be located at capping top, on the wall of inlet tube opposite side be equipped with outlet tube, the nozzle direction of the outlet tube
Diagonally downward；The bottom plate is the elliptical flat-plate being obliquely installed, and the shape of the elliptical flat-plate is matched with wall, the discharge port
On the side wall of the minimum point contacted with the elliptical flat-plate positioned at wall, the outside of discharge port is equipped with discharge port sealed set
Sealing door.
The operation principle of the utility model：Concentrate after concentration is sent into recycling can, feeds, is stirring from inlet tube
Under the action of motor, blender starts, and is stirred to the concentrate in recycling can, mixing speed is small, stirs evenly, and makes crystallization
Body uniformity reduces generation that is molten brilliant and gluing crystalline substance；After crystallizing a period of time, stop stirring, crystallization sedimentation, in the work of vacuum pump
Supernatant liquor extraction is entered into the storage of vacuum recycling can with lower；Crystallization is adhered on elliptical flat-plate and wall, and elliptical flat-plate is to incline
Tiltedly it is arranged and is matched with wall, discharge port is located on the side wall for the minimum point that wall is contacted with elliptical flat-plate；When discharging, envelope is opened
Mouth door, crystallization is dug using tool outward, since bottom plate is inclined plate, under the action of gravity and the holding power tilted upward, and knot
Brilliant friction becomes smaller, and can easily take out crystallization very much, discharge port in the minimum point of elliptical flat-plate, is not present dead angle, makes knot again
Crystalline substance discharging more convenient and quicker.
The beneficial effects of the utility model：Since the crystallization content of concentrate is small, need first to extract supernatant liquor out, it could be right
Crystallization discharges, and by the setting of inclined elliptical flat-plate and side discharge port, reduces the frictional force and tank body of crystallization
Dead angle keeps the discharging of crystallization convenient and efficient.
Further, the angle of inclination of the elliptical flat-plate is 8~15 °.While ensureing to discharge effect, difficult processing is reduced
Degree, more than 15 °, difficulty of processing becomes larger, and is less than 8 °, and discharging effect is small, and therefore, 8~15 ° are optimum angle value.
Further, the sealing door and discharge port are hinged, and the inside of sealing door is equipped with sealing strip.
Further, the inside of the sealing door and discharge port mortise-tenon joint, sealing door is equipped with sealing strip.
Hinged or mortise-tenon joint all easily sealing doors opening and closing operation, makes sealing effect more by sealing strip
It is good, avoid the leakage of concentrate.
Further, the nozzle of the outlet tube be equipped with for prevent from crystallizing across strainer.Make the separating effect of solid-liquid more
It is good, the concentration of aluminic acid liquid in supernatant liquor is reduced, ensures wastewater treatment efficiency and recovering effect.
Further, the top of the elliptical flat-plate is equipped with telescopic cyclic annular scraper plate.For the ease of to crystallization material discharging,
Cyclic annular scraper plate is arranged to telescopic, holds the side of cyclic annular scraper plate, repeatedly scrape back and forth, you can by the knot on elliptical flat-plate
Crystalline substance material scrapes.
