Description
Technical field
The utility model relates to chemical production equipment, is specifically related to a kind of for titanium white production acid hydrolysis tank.
Background technology
At present, titanium white production mainly contains two kinds of techniques, and one is sulfuric acid process, and one is chlorination process.The main process of Titanium White Production By Sulfuric Acid Process is: ilmenite powder and the vitriol oil are carried out acidolysis reaction and produces titanyl sulfate, then generates metatitanic acid through hydrolysis, and namely metatitanic acid obtains titanium dioxide product through calcining, pulverizing.This method can produce anatase titanium dioxide and Rutile type Titanium Dioxide.Production By Sulfuric Acid Process cost is low, and technology is more ripe, and equipment is simple, and anticorrosive easily solves.But long flow path, can only based on periodical operation, and production efficiency is low.
The critical process of sulfuric acid process utilizes the vitriol oil and ilmenite powder to carry out acidolysis reaction exactly, and this reaction, usually in acid hydrolysis tank, is carried out under agitation.Although this reaction is comparatively mature and stable, there is sulfuric acid, water consumption is large, produce a large amount of waste water and waste gas, problem big for environment pollution.
Summary of the invention
The utility model provides a kind of titanium white production acid hydrolysis tank, and main purpose improves the efficiency of acidolysis reaction in Titanium White Production By Sulfuric Acid Process process.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of titanium white production acid hydrolysis tank, comprises tank body and whipping appts, and whipping appts is used for stirred pot intracoelomic cavity material; Described tank body is arranged transparent dismountable cover plate, cover plate is arranged exhaust collection pipe; Described whipping appts comprises the stir shaft that motor and speed reduction unit drive, and stir shaft arranges stirring rake, and described stirring rake comprises the lower oar being arranged in oar on tank inner chamber top, being positioned at oar in the middle part of tank inner chamber, being positioned at tank inner chamber bottom; Stirring rake all adopts along stirring axisymmetric leaf structure, and the gradient that upper oar has the gradient of downward plug-flow, lower oar has upwards plug-flow, middle oar are horizontal whipped-up structure; Described inner tank wall is positioned at position near liquid level and arranges distributing fin, and the plate face of distributing fin is arranged obliquely along stirring rake turning direction.
Preferred: described stirring rake to be arranged through hole and/or stupefied bar.
Preferred: described tank wall arranges diaphany window.
The beneficial effects of the utility model: stirring rake is while stirring, the downward plug-flow material of upper oar, lower oar upwards plug-flow, the material in tank body is made not only to have the motion of horizontal direction, and there is the motion of vertical direction, material obtains more fully stirring, and has more contact reacts chances, is beneficial to sulfuric acid and ilmenite powder fully reacts.And violent washing away makes the part that ilmenite small-particle reacts away be washed away by sulfuric acid, increases surface-area rapidly, accelerated reaction process.Utilize distributing fin can strengthen the stirring and mixing effect of vessel edge further.Stirring rake structure is simple simultaneously, and profile is smooth and easy, and running resistance is little, avoids causing stirring and stagnates or burn the problems such as motor.The utility model can increase substantially the efficiency of acidolysis reaction, lays the foundation for other equipment supporting realize titanium white continuousization production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Introduce preferred embodiment of the present utility model and technique effect below in conjunction with accompanying drawing, but the technical solution of the utility model and design are not limited only to following preferred embodiment.
As shown in Figure 1 for titanium white production acid hydrolysis tank, comprise tank body 2 and whipping appts.Whipping appts is for stirring tank body 2 inner chamber material.The stir shaft 1 that whipping appts generally includes motor, speed reduction unit drives, stir shaft 1 is fixed on support 4 by bearing, and stir shaft 1 arranges stirring rake.This all belongs to conventional structure, therefore motor not illustrated in FIG., speed reduction unit.
Improvement of the present utility model is: described tank body 2 arranges transparent dismountable cover plate 7, cover plate 7 is arranged exhaust collection pipe 4.Open cover plate 7 can add materials, after reaction terminates, can material be discharged from the baiting valve 8 of tank body 2 lower end.Described whipping appts comprises the stir shaft 1 that motor and speed reduction unit drive, and stir shaft 1 arranges stirring rake, and described stirring rake comprises the lower oar 12 being arranged in oar 10 on tank body 2 inner chamber top, being positioned at oar 11 in the middle part of tank body 2 inner chamber, being positioned at tank body 2 inner chamber bottom.Stirring rake all adopts the leaf structure along stir shaft 1 symmetry, rotate smooth and easy, resistance is little, avoids overload to burn the problem such as motor.
Upper oar 10 has the gradient of downward plug-flow, lower oar 12 has the gradient of upwards plug-flow, middle oar 11 is horizontal whipped-up structure.The blade shape of stirring rake is not specifically limited, and can make straight plate or have the bent plate etc. of certain distortion.As long as will upward or below plug-flow then notice that blade and horizontal plane have constant slope when mounted, its structural principle and shape, similar are in the water screw of boats and ships or fan.
Stirring rake is while stirring, and upper oar 10 is plug-flow material downwards, and lower oar 12 upwards plug-flow, makes the material in tank body 2 not only have the motion of horizontal direction, and have the motion of vertical direction.Material obtains more fully stirring, and has more contact reacts chances, is beneficial to sulfuric acid and ilmenite powder fully reacts.And violent washing away makes the part that ilmenite small-particle reacts away be washed away by sulfuric acid, increases granule surface area rapidly, accelerated reaction process.Stirring rake structure is simple simultaneously, and profile is smooth and easy, and running resistance is little, avoids causing stirring and stagnates or burn the problems such as motor.
Described tank body 2 inwall is positioned at position near liquid level and arranges distributing fin 3, and the plate face of distributing fin 3 is arranged obliquely along stirring rake turning direction.In structure as shown in Figure 1, the state stirring rake of overlooking rotates clockwise, then distributing fin 3 as shown in the figure to the right, downwards up time extend.Can play the effect of downward for material water conservancy diversion like this.Utilize distributing fin 3 can strengthen the stirring and mixing effect at tank body 2 edge further.
Be more preferably and through hole 13 and/or stupefied bar are set on described stirring rake.Increase the effect be uniformly mixed, simultaneously because blade is vane-type, can not the anode sludge be adhered to.Acid hydrolysis tank of the present utility model also can carry out other improvement simultaneously, such as, on described upper tank body 20, arrange charging mechanism 6; Or described tank body 2 sidewall arranges diaphany window, be convenient to observe inner workings.The amount etc. that liquidometer 5 is convenient to control to add water can also be set, facilitate equipment use.
