With outstanding thickening effect, the thickener can thicken low concentration serum with crystal content being from 5 percent wt to 30 percent wt to more than 50 percent wt and meanwhile, can also control the size of crystal particles inside serum to ensure that obtained crystal has bigger particle diameter and narrower particle diameter distribution, thereby being suitable for thickening low concentration serum with the mother liquor being single saturated solution or containing other materials.
Description
One, technical field
The utility model relates to a kind of novel stiff device with backwash, belongs to the chemical industry equipment of thickening low concentration slurries.
Two, background technology
Common stiff device is not provided with the separated region of mother liquor backwash facility and expansion, cause the granularity of crystal in the slurries after the stiff and the percentage composition of crystal effectively not to control, be unfavorable for follow-up equipment steadily, work efficiently, can not guarantee the resultant crystal that has bigger particle diameter and narrower particle diameter to distribute simultaneously.
Three, summary of the invention
The purpose of this utility model is to provide a kind of novel stiff device, by mother liquor backwash facility is set, the content and the particle diameter of crystal in the slurries that obtain after the stiff are controlled, and can be realized when containing other insoluble material in the mother liquor, mother liquor separates with other material.
The technical solution of the utility model is: a kind of novel stiff device with backwash is characterized in that: be the vertical cylinder structure, return the district and the transition region at middle part and the elutriation district of bottom by the mother liquor on top and form.The drum diameter that the mother liquor on top returns the district is big, and the drum diameter in the elutriation district of bottom is little, and the transition region at middle part is a rounding bench-type structure.The cylinder top that mother liquor on top returns the district is provided with two material mouths of pipe, is provided with overflow weir in the cylinder between the two material mouths of pipe; Slurries discharging opening after being provided with densitometer mouth and densitometer rinse mouth and mother liquor backwash mouth and thickening on the cylinder in the elutriation district of bottom; The bottom of eluriating district's cylinder is a drain; The cylinder top that mother liquor on top returns the district is provided with slurry inlet and steam vent.
The utility model is provided with the densitometer mouth in the bottom of eluriating district's cylinder.
Two mother liquor backwash mouths of the utility model configuration, a place is located at the middle and lower part of eluriating district's cylinder, and another place is located at the bottom of eluriating district's cylinder.
The cylinder top that mother liquor of the present utility model returns the district is provided with hand-hole.
The utility model adopts the vertical cylinder structure, and upper diameter is bigger, for mother liquor returns the district; Lower diameter is less, for eluriating the district, and be provided with the backwash facility at mouth cylinder, adjusting by the mother liquor backwash volume, both can make the thickening of low concentration slurries, the size of crystal grain in the controlled again slurrying liquid, upper diameter is bigger, helps separating of other immiscible with it material that mother liquor and mother liquor carry secretly.The utility model stiff effect is obvious, can make that crystalline content is thickened to more than the crystalline content 50%wt at the low concentration slurries of 5%～30%wt scope in the slurries, can control simultaneously the size of crystal grain in the magma again, to guarantee that getable crystal has bigger particle diameter and narrower particle diameter distributes, be suitable for mother liquor and be containing in single saturated solution or the mother liquor enrichment of the low concentration slurries of other material, have broad application prospects.
Four, description of drawings
Fig. 1 is the schematic diagram of the utility model stiff device.
Among the figure: 1 returns the district for mother liquor; 2 is transition region; 3 for eluriating the district; 4 is mother liquor backwash mouth; 5 are the slurries discharging opening after the thickening; 6 is mother liquor backwash mouth; 7 is drain; 8 is the densitometer rinse mouth; 9 is the densitometer mouth; 10 is material outlet; 11 is material outlet; 12 overflow weir; 13 slurry inlet; 14 blow vents; 15 slurry inlet; 16 hand-holes.
Five, the specific embodiment
The utility model is made up of elutriation district 3 and transition region 2 that the mother liquor on top returns district 1 and bottom, is suitable for mother liquor and is the operating mode of carrying other insoluble material secretly in single saturated solution or the mother liquor.
The utility model is to realize like this; When containing other insoluble material in the mother liquor, it is bigger that the mother liquor on top returns district's 1 diameter, and be provided with adjustable for height overflow weir 12, mother liquor and other insoluble material of carrying secretly are at higher slice, after the material that density is lighter passes through overflow weir 12, flow out by the mouth of pipe 11, the heavier material of density is extracted out from the material mouth of pipe 10 under the overflow weir, and the realization mother liquor separates with other insoluble material.
Elutriation district 3 diameters of bottom are less, and are provided with mother liquor backwash facility.The slurries of low concentration divide one or more to enter stiff device transition region 2, and the sedimentation by crystal is able to enrichment.The backwash mother liquor is sent by pumping to the bottom of eluriating district 3, and mother liquor is upwards motion in the stiff device, and opposite with the direction of crystal sedimentation, the less crystal grain in the magma can not settle down, and take out on the top that rises to the stiff device with mother liquor.Also be provided with the densitometer mouth in elutriation district 3,, illustrate that the crystalline content in the magma is very few, adjust by the flow that reduces the backwash mother liquor if the magma density after the stiff does not reach setting value.The slurries that density reaches after the requirement enter next separation equipment by the downward-sloping discharging mouth of pipe 5.
For mother liquor is single saturated solution, can not establish movable overflow weir, also the mother liquor on top can be returned district 1 and transition region 2 and unite two into one, and diameter is identical with the elutriation district 3 of bottom.
Stiff with sulphur ammonium magma in the ammonium sulfate device is that example is described further below.
The utility model is achieved in that the sulphur ammonium magma of low concentration is by being pumped into stiff device slurry inlet 13,15, saturated ammonium sulfate liquor is by being pumped into stiff device ammonium sulfate liquor recoil mouth 4,6 earlier, reverse flow by backwash mother liquor and crystal sedimentation, the less sulphur ammonium crystal of particle returns district 1 along with the backwash ammonium sulfate liquor moves upward together through eluriating district 3 and transition region 2 to mother liquor, and the addition of mother liquor is controlled by the densitometer that links to each other with densitometer mouth 9.Sulphur ammonium magma after the thickening is discharged by slurries discharging opening 5, is sent to the charging aperture of centrifuge.
Owing to contain the part caprolactam in the ammonium sulfate liquor, mother liquor at the stiff device returns district 1, sulphur ammonium and caprolactam carry out layering, lighter caprolactam floats on the ammonium sulfate liquor, after overflow weir 12, flowed out by material outlet 11, the heavier ammonium sulfate liquor of lower floor's density is then extracted out by material outlet 10, and the realization caprolactam separates with ammonium sulfate liquor.
