Abstract
The present invention relates to a floating ball self-absorption pure titanium liquid art, which comprises an absorbing pipe, wherein, one end of the absorbing pipe is communicated with a pure titanium liquid pond. A floating ball is mounted in the inlet of the other end of the absorbing pipe. The inlet end of the absorbing pipe with the floating ball is arranged on the liquid surface of the mixed liquid of metatitanic acid and green copperas. At first, the mixed liquid of metatitanic acid and green copperas is the viscous liquid of large density. The buoyancy of the floating ball is large, therefore, the port of the inlet end of the absorbing pipe is toward upward and can not absorb liquid. The density of the upper layer of pure titanium liquid is decreased with the gradual delamination of the metatitanic acid and green copperas, therefore, the buoyancy of the floating ball is decreased. The port of the inlet end of the absorbing pipe is inserted into the cleaning titanium liquid layer in the slanting state and absorbs the pure titanium liquid automatically. The present invention makes use of the change of liquid density of the metatitanic acid and green copperas in sedimentation delamination state, therefore, the absorbing pipe with the floating ball can absorb the upper layer of the pure titanium liquid. The present invention has the advantages of high separating efficiency and safe and reliable operation, therefore, which is applicable to production plants of titanium pigment.
Description
[technical field]
The present invention relates to a kind of liquid separation technology, especially relate to a kind of floating ball self-sucking titanium liquid-cleaning technique that clear titanium liquid in metatitanic acid and the ferrous sulfate mixed liquor is separated.
[background technology]
The production process of Titanium White Production By Sulfuric Acid Process is: ilmenite is placed acidproof reactor, the dilute sulfuric acid of adding 20～30%, and stir, when being preheating to the 90 degree left and right sides, add the metatitanic acid hydrolysis crystal seed, the reducing agent of trivalent titanium ion solution, the ilmenite of pulverizing, continuous rising temperature in the time of reinforced, reinforced finishing temperature maintenance at little state that boils, ilmenite constantly is decomposed, do not cut off the water supply and solve metatitanic acid and ferrous sulfate, di-iron trioxide in the ore deposit also is decomposed and is reduced to ferrous sulfate, also corresponding generation calcium sulfate of calcium oxide and magnesia and magnesium sulfate are for compositions such as the mineral of diluted acid dissolving such as silica then remain in the slag, in the process of whole decomposition and hydrolysis, trivalent titanium ion constantly is consumed, need constantly replenish, the concentration that needs to keep titanium ion in entire reaction is decomposed fully and metatitanic acid hydrolysis end up to ilmenite at 0.5～1g/L.Finish after cold water filters, metatitanic acid separates with mother liquor, metatitanic acid is isolated the rugosity big slightly undecomposed slag of crude density slightly through the stage division such as the equipment such as hydrocyclone and shale shaking table of gravity separation from metatitanic acid, metatitanic acid is handled, is calcined through routine washing, bleaching, salt then, produces titanium dioxide through wet-milling, classification, surface treatment and drying and crushing.The by-product ferrous sulfate heptahydrate.
In above-mentioned production process, when metatitanic acid separates with mother liquor, to separate in metatitanic acid and the ferrous sulfate mixed liquor input settling tank, mixed liquor is thick suspension, along with the increase of sedimentation time, titanium liquid gradually with the copperas solution layering, clear titanium liquid density is littler than the inferior solution iron of sulfuric acid density, is positioned at the upper strata of liquid, and existing separation method all is to take manual method to separate, by Artificial Control suction pipe is inserted in the clear titanium liquid layer, in time clear titanium liquid is separated.This method both wasted time and energy, and was difficult to again control.
[summary of the invention]
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of floating ball self-sucking titanium liquid-cleaning technique, utilize floating ball device to draw clear titanium liquid automatically and separate, reach and raise the efficiency and reliable purpose.
The technical solution adopted for the present invention to solve the technical problems is: a kind of floating ball self-sucking titanium liquid-cleaning technique, comprise suction pipe, one end of suction pipe communicates with clear titanium liquid pool, import department at the suction pipe other end is set with ball float, the suction pipe entrance point that will be fitted with ball float then places the liquid level of metatitanic acid and ferrous sulfate mixed liquor, during beginning, because metatitanic acid and ferrous sulfate mixed liquor are the big thick liquid of density, the suffered buoyancy of ball float is big, and the port that makes the suction pipe import up and can not imbibition; Along with the layering gradually of metatitanic acid liquid and ferrous sulfate liquid, the density of the clear titanium liquid in upper strata reduces gradually, and the suffered buoyancy of ball float reduces, and makes the suction pipe inlet ports tilt to insert in the clear titanium liquid layer, and clear titanium liquid is siphoned away automatically.
On described ball float, be fitted with balancing weight, and, make the port of suction pipe import tilt to insert in the clear titanium liquid layer, clear titanium liquid is siphoned away automatically by adjusting the quality of balancing weight.
Described suction pipe adopts soft material.
Described ball float is cylindrical, is provided with jack in the cylinder, is contained on the suction pipe by this jack sleeve.
The invention has the beneficial effects as follows: utilize the variation of metatitanic acid and ferrous sulfate mixed liquor fluid density when the sedimentation layering, make the suction pipe that is set with ball float automatically the clear titanium liquid in upper strata be siphoned away separation, has the separative efficiency height, advantage safe and reliable to operation, the manufacturer that is suitable for titanium dioxide applies.
[description of drawings]
Fig. 1 is an apparatus structure schematic diagram of the present invention;
Among the figure: 1-suction pipe, 2-ball float, 3-balancing weight, 4-import, 5-metatitanic acid and ferrous sulfate mixed liquor, 6-settling tank.
[specific embodiment]
The present invention is further described below in conjunction with drawings and Examples.
Referring to Fig. 1, a kind of floating ball self-sucking titanium liquid-cleaning technique comprises suction pipe 1, this suction pipe 1 adopts soft material, and an end of suction pipe 1 communicates with clear titanium liquid pool, in an embodiment, one end of suction pipe 1 is installed in the bottom of settling tank 6, and the passage of the bottom by settling tank 6 communicates with clear titanium liquid pool; Import 4 places at suction pipe 1 other end are set with ball float 2, this ball float 2 is cylindrical, be provided with jack in the cylinder, and be contained on the suction pipe 1 by this jack sleeve, and on ball float 2, be fitted with balancing weight 3, import 4 ends that will be fitted with the suction pipe of ball float 2 and balancing weight 3 then place on the liquid level of metatitanic acid and ferrous sulfate mixed liquor 5, during beginning, because metatitanic acid and ferrous sulfate mixed liquor 5 are the big even thick liquid of density, ball float 2 suffered buoyancy are big, by adjusting the quality of balancing weight 3, the port that makes suction pipe 1 import 4 up and can not imbibition; Along with metatitanic acid liquid and ferrous sulfate solution layering gradually, the density of the clear titanium liquid in upper strata reduces gradually, and ball float 2 suffered buoyancy reduce, and makes suction pipe 1 import 4 ports tilt to insert in the clear titanium liquid layer, and clear titanium liquid is siphoned away automatically.The present invention utilizes the variation of metatitanic acid and ferrous sulfate mixed liquor fluid density when the sedimentation layering, make the suction pipe that is set with ball float automatically the clear titanium liquid in upper strata be siphoned away separation, have the separative efficiency height, advantage safe and reliable to operation, the manufacturer that is suitable for titanium dioxide applies.
