Description

A kind of high intensity Potash Industry crystallizer of simple support

Technical field

The utility model is related to Potash Industry crystallizer technology field, more particularly to a kind of high intensity potassium of simple support Salt industrial crystallizer.

Background technology

Using very extensively in the industries such as chemical industry, food, pharmacy, metallurgy, common crystallizer has outside pressure for mechanical crystallization Circular form (FC types) crystallizer, grading type (Oslo types) crystallizer, DTB types crystallizer, DP types crystallizer, Messo types are rapid Flow crystallizer.

DTB type crystallizers are a kind of very high crystallizers of the efficiency occurred the fifties in last century, its crystal property is good, Larger crystal grain, generally up to 0.6mm~1.2mm can be produced, production intensity is high, and is not easy to scab, and is continuous crystalizer One of broad form.The Main Tectonic Characteristics of the type crystallizer have a guide shell for centre, and guide shell surrounding has cylindrical shape gear Plate, formula agitator arm of boosting is provided in guide shell at lower end, and crystallizer passes through impeller rotation forces material when working Slurry is flowed up out of guide shell, and slurry flows downward after reaching liquid level along the annulus between cylinder baffle and guide shell again It to crystalliser feet, and is sucked in guide shell and flows up again by impeller, so as to form a closed cycle, crystal is cycling Good mixing in the process, then the process regulation solution degree of supersaturation of crystallization power and crystal growth speed are influenced by controlling Rate, and then slurry is made constantly to grow the big and uniform crystal of granularity in this cyclic process.At present, DTB types crystallizer is being changed It is widely used in work, food and pharmaceutical industry.

DP type crystallizers are developed in the seventies in last century, are considered as the improvement of DTB type crystallizers, with DTB type crystallizers The main distinction be that DTB types crystallizers only installs propeller in guide shell, push circulation fluid upwards, and DP types crystallizer is then One group of counter rotating propeller is also provided in the annulus on the outside of guide shell, pushes circulation fluid, inside and outside two groups of propellers downwards Synchronous rotary promotes circulation fluid efficient circulation.The characteristics of type crystallizer, is that diameter of propeller blade is larger, can under same loop state Wheel speed is effectively reduced, so as to reduce secondary nucleation rate, compared with DTB type crystallizers, nucleation rate about declines 1/3, by Be greatly reduced in nucleation amount, the particle mean size of crystal significantly increases, by taking ammonium sulfate as an example, crystal size can grow to 0.9mm~ 1.3mm.But the shortcomings that type crystallizer is that accuracy of manufacture requirement is high, manufacture, maintenance difficult.

DTB type crystallizers are generally used in sylvite industry, as Chinese patent CN104722098A, CN103073030A, but these patents are all crystallizing relative separation when producing without solving crystallization raw material emphatically with crystalline product Problem, also without solving the problems, such as the circulation crystallization of bulky grain raw material, it is even more impossible to further improve the pulp density of race way, to crystalline substance Body growth, discharge and raising crystallizer treating capacity are unfavorable.Such as CN103073030A its raw material granularity in actual production controls Below -2mm, discharge concentration 28%~32% according to crystallizer working condition its slurry circulation concentration less than 28%, gives birth to crystal grain Length is very unfavorable, while main chloride containing potassium and sodium chloride are answered in its underflow discharge system, but actual still containing 5%~20% light Halogen stone；CN104722098A solves emphatically slurry and is cut in cyclic process by sharp guide shell upper and lower side cross section notch It cuts, the problem of so as to which crystal grains fine, nucleus be caused to increase, there is also crystalline products in actual production to be mingled with certain proportion original The problem of material, it is all powder that it, which crystallizes raw material, in addition, does not solve crystallization and the circulatory problems of bulky grain raw material.

Chinese patent CN201610151720.7, a kind of mechanical crystallizer of Potash Industry, including crystallizer body, outside Cylinder, guide shell, feed baffle, main agitating device, bowl-type baffle and discharge agitating device, the outer barrel, guide shell, feed gear Plate, bowl-type baffle are fixedly connected with crystallizer body, and the main agitating device, discharge agitating device pass through stent and bearing and knot Brilliant device body connection, the crystallizer body upper end are equipped with mother liquor overflow mouth, and bottom is equipped with discharge gate, and the bowl-type baffle is located at Immediately below guide shell, in the low domes of intermediate high surrounding, bottom is surrounded by material intercommunicating pore for bottom.Utilize the invention pair Potassium chloride and potassium sulfate carry out crystallization production, and raw material feeding granularity can be made to be amplified to 8mm, crystallisation cycle slurry and crystalline product phase To separation, Xun Huan slurry mass concentration and crystallizer treating capacity are effectively improved, increases crystalline product granularity, is reduced in crystalline product Raw material entrainment rate, obtain better crystallization effect.

But mechanical crystallizer is due to its structure crystalline device top load（Top platform, upper driving and stirring shaft assembly etc.） By the section bar intensity for increasing top platform（Increase cost）, while strengthen the stiffness of outer barrel again, lead to entire top load It crosses plus rear platform is added to be transferred on strengthened cylinder.It is such it is complicated, be not easy to make, how of high cost materials are etc. lacks.
