Description
Technical field
The utility model relates to salt lake chemical fields, and in particular to a kind of to produce potassium chloride using cold crystallization direct flotation method
When can prevent the crystallizer of underflow blockage.]
Technical background
Cold crystallization direct flotation method production potassium chloride technology is to produce one of potash fertilizer technology the most universal and traditional cold point
Solution direct flotation law technology compares, and solves the problems, such as that product granularity is small, i.e., powdery potassium chloride is upgraded to crystal grain shape, made
It is preferable to obtain product granularity, color.But crystallizer wants material during producing potassium chloride using cold crystallization direct flotation method
Ask higher, by mixed impurity in the obtained material of the drought mode of adopting and carnallite agglomerate meeting so that crystallizer underflow pipe plug
Plug, currently the only method are to interrupt production, are resumed production after the material for discharging crystallizer underflow blockage, a large amount of to arrange
It lets off journey and causes material and waste of time, directly affect the production efficiency of whole system.However, if in process flow
It is middle to greatly increase production cost again using crushing device.
Summary of the invention
To solve problems of the prior art, the utility model provides a kind of crystallizer for preventing underflow blockage,
By fence of the crystalliser feet clipping room away from 4cm to 5cm by material biggish in crystallizer agglomerate enter underflow pipe it
Before be filtered, and by the rotary force of the propeller in crystallizer make bulk material agglomerate with fence shock become smaller even
Dissolution, while the intracorporal underflow pipe entrance structure of crystallizer cylinder is transformed, so that lesser material agglomerates also not after fence filters
Enter underflow pipe, easily to solve impurity and carnallite agglomeration blocking crystallizer when using cold crystallization direct flotation method production potassium chloride
The problem of underflow pipe.
To realize the purpose of this utility model, the utility model uses following technical scheme:
A kind of crystallizer preventing underflow blockage includes variable-frequency motor, propeller, overflow pipe, guide shell, tubular gear
Plate, crystallizer cylinder, underflow tube inlet, fence, impurity delivery pipe, underflow pipe.The variable-frequency motor is mounted on crystallizer cylinder
At the top of body, the propeller is fixed on the rotor of variable-frequency motor and extends in crystallizer cylinder, the overflow pipe peace
The position on the upper side mounted in crystallizer cylinder side, the guide shell is located at crystallizer center and wraps up propeller, described
Cylindrical baffle is located among guide shell and crystallizer cylinder, the underflow pipe be mounted on crystallizer cylinder side-lower and with it is described
The intracorporal underflow tube inlet connection of crystallizer cylinder, the fence is mounted on crystallizer cylinder body bottom and close to underflow tube inlet
Upper end, crystallizer cylinder body bottom side is equipped with an impurity delivery pipe.
Further, the fence is by other parts in the underflow tube inlet of crystallizer cylinder body bottom and crystallizer cylinder
It is completely separated.
Further, the fence is the structure with a horizontal plane and an inclined-plane, and the inclined-plane leans on
Nearly underflow pipe inlet side has simultaneously supported certain space in bottom with a horizontal plane for underflow tube inlet.
Further, the fence is by the reinforcing bar of longitudinal pitch 4cm to 5cm arrangement and laterally with suitable spacing row
The reinforcement welding of column forms.
Further, the underflow tube inlet is the tubular structure for having certain length to have 90 degree of elbows, described curved
The opening direction of head is identical as the direction of rotation of propeller.
In use, new mine is covered on old mine heap, soak to obtain completely soft carnallite by certain time, it will
Soft carnallite, smart potassium mother liquor, fresh water are added in crystallizer cylinder from crystallizer top, and variable-frequency motor driving rotation paddle stirs
It mixes, big material agglomeration is filtered by the fence of bottom before entering underflow pipe, while the bevel structure of fence is by spiral shell
The rotary force for revolving paddle, which smashes big material agglomeration, even to be dissolved, and is continued by the filtered lesser material agglomeration of fence with spiral shell

Into in underflow pipe.After material is reduced in crystallizer cylinder, according to the component of material, it is mixed that new raw ore is added in production process
It closes, after the long period after crystallizer cylinder body bottom has accumulated a large amount of impurity waste materials, stops production and pass through impurity delivery pipe,
Crystallizer cylinder impurity is purged, useful material is recycled, while each component of crystallizer is safeguarded.
Compared with prior art, the present invention the utility model has the following beneficial effects:
1. the fence of installation by the underflow tube inlet of crystalliser feet with other spaces of crystallizer cylinder are complete separates, will be big
Material agglomeration is filtered before entering underflow pipe, at the same the bevel structure of fence by the rotary force of propeller by big object
Material agglomeration, which smashes, even dissolves, and has achieved the purpose that prevent bulk materials from blocking underflow pipe, has prevented production disruption, improve production
Efficiency reduces costs, and has prevented material waste.
2. the underflow tube inlet with 90 degree of elbows of installation, due to the direction of rotation phase of its opening direction and propeller
Together, the opposite direction for making the liquid inside crystallizer prolong propeller rotation enters underflow pipe in a manner of flowing backward, in rotation paddle centrifugation
Lesser material agglomeration is also not easily accessible in underflow pipe after fence filters under the action of power, and reaching prevents lesser material from agglomerating
The purpose that underflow pipe is blocked after accumulation, further prevents production disruption, improves production efficiency, prevented material waste.
It, can 3. the underflow tube inlet with certain length increases underflow tube inlet to the space at crystallizer cylinder bottom
More impurity are precipitated, achieve the purpose that extend the continuous production time, the impurity discharge outlet of bottom can effectively discharge the miscellaneous of precipitating
Matter simultaneously can be used for material recycle, prevent material waste.
4. the solution and impurity parking space due to underflow pipe blockage problem increase, make production can long-time continuous stable
Progress, can be mixed again, be combined according to raw ore component in continuous production, it is more stable to have reached crystallizer control parameter,
Production target is optimized, the purpose of the potassium rate of recovery is improved.
