Abstract
The utility model relates to a device for separating cobalt sulfate crystal, which comprises a crystallizing kettle, a centrifuge and a mother liquid recovery tank. The device is characterized in that the mother liquid recovery tank is connected with one end of a liquid return pump, the other end of the liquid return pump is connected with one end of a cooler, and the other end of the cooler is communicated with the top of the crystallizing kettle. The device has no strict requirement for the specific gravity of concentrated solution, and the crystal separation time is shortened from the original 15-16 hours to 7-8 hours; since the cobalt sulfate crystals are continuously separated out, the mother liquid returned to the crystallizing kettle relatively reduce the concentration of the cobalt sulfate crystals in the solution, the load of a stirring motor is reduced, and the motor burnout or junction box damage is avoided; and since materials continuous flow out, the material outlet is not blocked by sediments, and the operation is simplified.
Description
Technical field
The utility model relates to a kind of device of rose vitriol Crystallization Separation.
Background technology
At present the usual method of producing rose vitriol in hydrometallurgy is to contain the rose vitriol dilute solution of cobalt amount 80g/l-140g/l, through the evaporation concentration dehydration, after making the proportion of cobalt sulfate solution concentration reach 1.5-1.54, put into crystallization kettle, feed the water cooling crystallization in the chuck.When solution temperature was cooled to below 30 ℃, the rose vitriol crystal was isolated in the centrifugation of beginning blowing.Because the proportion of cobalt sulfate solution is wayward, cross single batch of output of low influence, too highly make that easily the rose vitriol xln is too many, cause the motor load overload to cause that motor burns out or shaft joint damages.Consuming time in addition too much, crystallization time reached 15 hours-16 hours and the xln thing easily stops up material outlet, influenced ordinary production.How, become the problem that industry must solve by the improvement of device being avoided the appearance of the problems referred to above.
The utility model content
The purpose of this utility model provides a kind of device of rose vitriol Crystallization Separation.
The technical solution adopted in the utility model is:
A kind of device of rose vitriol Crystallization Separation comprises crystallization kettle, whizzer and mother liquor pond for recovering, described mother liquor pond for recovering with return liquid pump one end and be connected, the described liquid pump the other end that returns is connected with water cooler one end, the described water cooler the other end is communicated with the top of crystallization kettle.
Described whizzer is generic centrifuge or automatic a kind of in the discharging formula whizzer.
The utility model solved the time that exists in the rose vitriol Crystallization Separation long, motor load is big, the problem of the easy congestion affects ordinary production of material outlet.Principle of the present utility model is to put into about evaporating kettle evaporation concentration to 1.54 at the cobalt sulfate solution of 80g/l-140g/l containing the cobalt amount, put into crystallization kettle, chuck feeds water coolant, and adds small amount of seeds, treats that solution temperature drops to about 70 ℃ can carry out centrifugation.The unlap of isolated rose vitriol crystal, the mother liquor of isolating behind the rose vitriol crystal enters crystallization in the crystallization kettle by returning liquid pump after by the external cooler cooling again.Fractional crystallization continuously is until finishing.
Crystallization Separation device of the present utility model is compared with former Crystallization Separation device, and adding heat transfer area is 30M
2-50M
2Heat exchanger with return liquid pump, and this cover add-on device can be shared with many crystallization kettles.Make cooling performance improve greatly, shortened the time,, then can enhance productivity greatly if change centrifugal separation equipment into automatic discharging formula.
The utility model is not strict with the proportion of concentrated solution through after improving, and the Crystallization Separation time shortened to 7 hours-8 hours by original 15 hours-16 hours; Owing to constantly the rose vitriol crystal separation is gone out, mother liquor makes the rose vitriol crystalline concentration in the solution reduce relatively after returning crystallization kettle, has reduced the load of agitator motor, can not take place that motor burns out or shaft joint damages phenomenon; Precipitation can not take place and stop up because of flowing out continuously yet in material outlet, makes operation become easy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein: 1, crystallization kettle, 2, whizzer, 3, the mother liquor pond for recovering, 4, return liquid pump, 5, water cooler.
Embodiment
As shown in Figure 1, the device of a kind of rose vitriol Crystallization Separation of the present utility model comprises crystallization kettle 1, whizzer 2 and mother liquor pond for recovering 3, mother liquor pond for recovering 3 with return liquid pump 4 one ends and be connected, return liquid pump 4 the other ends and be connected with water cooler 5 one ends, water cooler 5 the other ends are communicated with the top of crystallization kettle 1.Whizzer 2 is generic centrifuge or automatic a kind of in the discharging formula whizzer.
The utility model will contain the cobalt amount and put into about evaporating kettle evaporation concentration to 1.54 at the cobalt sulfate solution of 80g/l-140g/l, put into crystallization kettle, chuck feeds water coolant, and adds small amount of seeds, treats that solution temperature drops to about 70 ℃ can carry out centrifugation.The unlap of isolated rose vitriol crystal, the mother liquor of isolating behind the rose vitriol crystal enters crystallization in the crystallization kettle by returning liquid pump after by the external cooler cooling again.Fractional crystallization continuously is until finishing.
Claims (2)
