Description

Technical Field

[0001] The present invention relates to the technical field of potassium salt beneficiation, and particularly to an automated flotation system for potassium chloride in a magnesium sulfate subtype salt lake. Background Art

[0002] Xitai Jinaier Lake belongs to a magnesium sulfate subtype salt lake. The brine development of this salt lake makes full use of the characteristics of its resource endowment. The main steps for producing potassium sulfate products by the conversion method are as follows: First, in the ore-forming stage of the salt pan, the processes of segmented solar evaporation of brine and brine mixing are adopted to form potassium salt ore into potassium mixed salt ore and carnallite ore. Subsequently, a conversion flotation process is used to prepare the intermediate product of kainite, and a cold decomposition - positive flotation process is used to prepare the intermediate product of potassium chloride. Finally, potassium sulfate products are obtained through two-stage reaction conversion. The potassium salt ore sun-dried in the salt pan generally exists in the form of double salts and mixed salts. Generally, the target product is obtained after decomposition or conversion, and then impurity separation is carried out through the flotation process. Currently, the flotation process is an indispensable step in the production of potash fertilizer from salt lake brine, which is related to the production efficiency and final product quality of the product.

[0044] Embodiment 2

[0045] Refer to Figure 1 , an automated flotation system for potassium chloride in a magnesium sulfate subtype salt lake. The raw material is 220 t / h carnallite ore (potassium ion content is 6.85%, magnesium ion content is 8.16%, chloride ion content is 27.41%, sulfate ion content is 13.76%). It is transported from the ore bin 1 to the decomposition tank one 2 by belt, and is proportioned with carnallite raw ore: mother liquor: fresh water at a ratio of 1:0.3:0.07. 65 m of mother liquor and 15 m of fresh water are added to the decomposition tank one 2 3 / h and fresh water 15 m3 After the liquid level reaches the stirring blades, start stirring. When the liquid level reaches half of the entire tank body, start the belt to convey materials to the decomposition tank 1-2. After the decomposition tank 1-2 is filled with slurry, it overflows to the decomposition tank 2-3. After the liquid level reaches, start stirring. When the decomposition tank 2-3 is filled with slurry, it overflows to the decomposition tank 3-4. After the liquid level reaches, start stirring. Stir for 2 hours at room temperature. Add a certain amount of flotation reagent to the decomposition tank 3-4. The slurry flows by gravity through the pipeline to the foam collection tank 2 of the flotation machine 2-6 (rougher). When there is foam overflow in the foam collection tank 2 of the flotation machine 2-6 (rougher), start the scraper to scrape the foam. The foam is scraped into the foam collection tank 1 of the flotation machine 1-5 (cleaner). The tail liquid of the flotation machine 1-5 and the flotation machine 2-6 flows through the bottom pipeline to the foam collection tank 3 of the flotation machine 3-7 (tail selector), and is discharged to the tail salt tank through the pipeline of the foam collection tank 3 (tail selector). The foam in the foam collection tank 3 of the flotation machine 3-7 (tail selector) is scraped by the scraper into the rougher of the flotation machine 2-6. The foam in the foam collection tank 1 of the flotation machine 1-5 (cleaner) flows by gravity to the belt filter 15. After solid-liquid separation, it is the solid potassium chloride product. In this case, the employees of the first shift adopted a detailed observation method, observed the liquid level of the flotation tank every 5 minutes, and when controlling the valve opening, adhered to the principle of adjusting in small increments multiple times. However, when the employees of the first shift adjusted the liquid level, they were too dependent on the fixed adjustment mode and failed to change flexibly according to the actual production situation. When facing some emergencies, the liquid level adjustment was not timely. These different factors led to the instability of the grade and output of the potassium chloride product. The potassium content of the obtained potassium chloride product is 37.08%, the magnesium ion content is 1.00%, the chloride ion content is 38.12%, the sulfate ion content is 1.27%, the output is 36.58 t / h, and the total potassium recovery rate is 90%.

[0046] Example 3

[0047] Refer to Figure 1 , the raw material of an automated flotation system for potassium chloride in a magnesium sulfate subtype salt lake is 220 t / h of carnallite ore (the potassium ion content is 6.85%, the magnesium ion content is 8.16%, the chloride ion content is 27.41%, and the sulfate ion content is 13.76%). It is conveyed from the ore bin 1 to the decomposition tank 1-2 by belt. The proportion of carnallite raw ore: mother liquor: fresh water is 1:0.3:0.07. Add 65 m 3 / h of mother liquor and 15 m 3 / h. Start stirring after the liquid level reaches the stirring blades. When the liquid level reaches half of the entire tank body, start the belt to convey materials to the first decomposition tank 2. After the first decomposition tank 2 is filled with slurry, it overflows to the second decomposition tank 3. Start stirring after the liquid level reaches. When the second decomposition tank 3 is filled with slurry, it overflows to the third decomposition tank 4. Start stirring after the liquid level reaches. Stir for 2h at normal temperature in all cases. Add a certain amount of flotation reagent to the third decomposition tank 4. The slurry flows by gravity through a pipeline to the foam collection tank 2 (rougher tank) of the second flotation machine 6. Start the scraper conveyor to scrape the foam when there is foam overflow in the foam collection tank 2 (rougher tank) of the second flotation machine 6. Scrape the foam into the foam collection tank 1 (cleaner tank) of the first flotation machine 5. The tail liquid of the first flotation machine 5 and the second flotation machine 6 flows through the bottom pipeline to the foam collection tank 3 (tailings tank) of the third flotation machine 7 and is discharged to the tail salt tank through the pipeline of the foam collection tank 3 (tailings tank). The foam in the foam collection tank 3 (tailings tank) of the third flotation machine 7 is scraped by the scraper into the rougher tank of the second flotation machine 6. The foam in the foam collection tank 1 (cleaner tank) of the first flotation machine 5 flows by gravity to the belt filter 15 and is separated into solid potassium chloride products through solid-liquid separation. In this case, when the employees of the second shift were operating, they mainly judged the liquid level of the flotation cell based on personal experience, and the observation frequency was about once every 15 minutes. When controlling the valve opening, they were used to making large adjustments to quickly change the liquid level. Compared with the operation method of the first shift personnel in Case 1, this method makes the liquid level fluctuate greatly and is affected by subjective judgments during operation, observation time intervals and other influencing factors, resulting in unstable quality and output of potassium chloride products. The obtained potassium chloride product has a potassium content of 37.06%, a magnesium ion content of 0.44%, a chloride ion content of 38.23%, a sulfate ion content of 1.17%, an output of 34.56t / h, and a total potassium recovery rate of 85%.

[0048] Example 4

[0049] An automated flotation system for potassium chloride in a magnesium sulfate subtype salt lake. The raw material is 220t / h of carnallite ore (with a potassium ion content of 6.85%, a magnesium ion content of 8.16%, a chloride ion content of 27.41%, and a sulfate ion content of 13.76%). It is conveyed from the ore bin 1 to the first decomposition tank 2 by a belt. The proportion of carnallite raw ore: mother liquor: fresh water is 1:0.3:0.07 for batching. Add 65m 3 / h of mother liquor and 15m 3 / h. Start stirring after the liquid level reaches the stirring blades. When the liquid level reaches half of the entire tank, start the belt to convey materials to the first decomposition tank 2. After the first decomposition tank 2 is filled with slurry, it overflows to the second decomposition tank 3. Start stirring after the liquid level reaches. When the second decomposition tank 3 is filled with slurry, it overflows to the third decomposition tank 4. Start stirring after the liquid level reaches. Stir at normal temperature for 2 hours. Add a certain amount of flotation reagent to the third decomposition tank 4. The slurry flows by gravity through a pipeline to the foam collection tank 2 (rougher) of the second flotation machine 6. Start the scraper to scrape the foam when there is foam overflow in the foam collection tank 2 (rougher) of the second flotation machine 6. The foam is scraped into the foam collection tank 1 (cleaner) of the first flotation machine 5. By installing level gauges 9, 10, and 11 in the first flotation machine 5, the second flotation machine 6, and the third flotation machine 7 to control the opening degrees of solenoid valves 12, 13, and 14 to adjust the liquid level. The tail liquid flows to the foam collection tank 3 (tailings selection tank) of the third flotation machine 7 through the solenoid valves 12 and 13 on the bottom pipelines of the first flotation machine 5 and the second flotation machine 6 to control the opening degrees of the valves, and is discharged to the tail salt tank through the pipeline on the foam collection tank 3 (tailings selection tank) controlled by the 14 - solenoid valve. The foam in the foam collection tank 3 (tailings selection tank) of the third flotation machine 7 is scraped into the foam collection tank 2 (rougher) of the second flotation machine 6. The foam in the foam collection tank 1 (cleaner) of the first flotation machine 5 flows by gravity to the belt filter 15 and is separated into solid potassium chloride products through solid - liquid separation. In this case, the liquid level control of the flotation tank relies on advanced level gauges for real - time and precise detection, and the opening degrees of the solenoid valves are intelligently controlled based on the detected data, so as to realize the dynamic optimization adjustment of the liquid level of the flotation tank. This intelligent control scheme, compared with the traditional manual operation, the most significant advantage lies in timeliness. Once there is a slight change in the liquid level, the system can quickly capture the signal and immediately adjust the opening degree of the solenoid valve, avoiding the problem of reaction lag that may occur in manual control. With this almost real - time response speed, the liquid level is always maintained in an ideal state, not only effectively improving the stability of the product quality, but also greatly improving the production efficiency, ensuring that both the product grade and output reach relatively high standards. The obtained potassium chloride product has a potassium content of 38.37%, a magnesium ion content of 0.96%, a chloride ion content of 38.56%, a sulfate ion content of 1.17%, a production output of 39.28 t / h, and a total potassium recovery rate of 100%.
