Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a high-efficiency intelligent phosphate flotation cell. Background Technology

[0002] Phosphate ore flotation technology utilizes the differences in interfacial properties of phosphate ore for separation, enrichment, and refining. The flotation cell is a crucial piece of equipment in the phosphate ore flotation process. Its working principle involves mixing phosphate ore with reagents to form a slurry, which is then injected into the flotation cell. After stirring by an agitator, air is injected into the slurry through an air distributor, forming bubbles. Hydrophobic mineral particles adhere to these bubbles and rise, eventually floating to the surface as foam. This foam is then collected by a scraper, while non-hydrophilic mineral particles settle back into the slurry. Currently, existing air distributors have a single aeration hole size, often resulting in insufficient bubble formation and ineffective capture of the minerals to be flotated, thus affecting the flotation effect. Furthermore, the failure to promptly detect changes in the foam layer in the flotation cell makes it difficult for the scraper to collect the foam, or excessive foam that is not promptly scraped away deteriorates the flotation effect. Additionally, the foam scraped out by the scraper during the flotation process may not dissipate in time in the side channels, easily overflowing the cells, causing ore loss and environmental pollution. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a high-efficiency intelligent phosphate rock flotation cell that enables efficient bubble destruction during flotation and improves the flotation effect.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A high-efficiency intelligent phosphate rock flotation cell includes a flotation cell body, which is divided into multiple tanks by multiple baffles. Each tank is equipped with a stirring device. The top of both sides of the flotation cell body is provided with grooves for foam to flow out, and a laser bubble breaker is provided at one end of the groove.

[0006] The above-mentioned flotation cell body is equipped with infrared liquid level scanners at both ends of the top. The infrared liquid level scanners are divided into infrared output devices and infrared receiving devices.

[0007] The bottom of the aforementioned partition is provided with through holes to allow liquid to flow through the bottom of each tank.

[0008] The aforementioned stirring device is driven by a stirring motor at the top of the flotation cell body, and each stirring device is equipped with a stirring motor.

[0009] In a preferred embodiment, the tops of the stirring devices in each of the aforementioned tanks are connected together by pulleys, and a stirring motor drives multiple stirring devices to rotate.

[0010] The aforementioned stirring device is equipped with a stirring shaft, and an air distributor is located at the bottom of the stirring shaft. The air distributor is used for aeration to form bubbles.

[0011] The air distributor described above is cylindrical, with a blocking plate at the bottom and multiple rows of air holes on the outer circumference of the cylinder.

[0012] The aforementioned multiple rows of air holes are formed by axially evenly spaced circular holes of varying diameters.

[0013] The centers of the air holes in adjacent rows are staggered.

[0014] The aforementioned multi-row air holes have two different hole diameters.

[0015] This invention provides a high-efficiency intelligent phosphate rock flotation cell. The aeration holes in the air distributor are improved, with uniformly distributed, varying sizes to generate more bubbles, which is beneficial for capturing hydrophobic mineral particles, resulting in better flotation and higher efficiency. An infrared level gauge installed on the phosphate rock flotation cell body and an air distributor installed at the bottom of the flotation machine's agitator are linked. The infrared level scanner detects the height of the foam layer. When the foam layer is too high, the air distributor automatically reduces the aeration rate to decrease bubble generation; when the foam layer is too low, the air distributor automatically increases the aeration rate to increase bubble generation, achieving intelligent and automated equipment. Laser bubble breaking is used, which, compared to traditional water flushing for bubble breaking, results in faster and more thorough foam destruction and reduces water consumption.

[0024] like Figure 1-6 As shown, a high-efficiency intelligent phosphate rock flotation cell includes a flotation cell body 1. The flotation cell body 1 is provided with multiple partitions 2 to divide the flotation cell body 1 into multiple tanks. Each tank is provided with a stirring device 3. The top of both sides of the flotation cell body 1 is provided with grooves 4 for foam to flow out. One end of the grooves 4 is provided with a laser bubble breaker 6.

[0025] The above-mentioned flotation cell body 1 is equipped with infrared liquid level scanners 5 at both ends of the top. The infrared liquid level scanners 5 are divided into infrared output devices and infrared receiving devices.

[0026] The bottom of the aforementioned partition 2 is provided with through holes to allow liquid to flow through the bottom of each tank.

[0027] The aforementioned stirring device 3 is driven by a stirring motor at the top of the flotation cell body 1, and each stirring device 3 is equipped with a stirring motor.

[0028] In the preferred embodiment, the tops of the stirring devices 3 in each of the aforementioned tanks are connected together by pulleys, and a single stirring motor drives multiple stirring devices 3 to rotate. Connecting them by pulleys requires only one drive motor, resulting in lower cost and higher energy efficiency, but the structure is slightly more complex.

[0029] The aforementioned stirring device 3 is equipped with a stirring shaft 7, and an air distributor 8 is provided at the bottom of the stirring shaft 7. The air distributor 8 is used for aeration to form bubbles.

[0030] The air distributor 8 can be connected to the hollow stirring shaft 7, with air supplied by a rotary joint at the top of the stirring shaft 7, or it can be formed by a plate body that does not rotate with the stirring shaft 7, with air supplied by a pipe on the side of the plate body.

[0031] The air distributor 8 mentioned above is cylindrical, with a blocking plate 9 at the bottom and multiple rows of air holes 10 on the outer circumference of the cylindrical part.

[0032] The aforementioned multi-row air holes 10 are formed by axially evenly spaced circular holes of various diameters.

[0033] The centers of the air holes 10 in the adjacent rows are staggered.

[0034] The aforementioned multi-row air holes 10 have two different hole diameters.

[0035] Example 1:

[0036] A high-efficiency intelligent phosphate rock flotation cell includes a phosphate rock flotation cell body. Infrared level gauges are installed at both ends of the upper part of the phosphate rock flotation cell body. A laser bubble breaker is also installed at one end of the upper part of the phosphate rock flotation cell body. An air distributor is installed at the bottom of the flotation machine's agitator inside the phosphate rock flotation cell body. Numerous aeration holes with different diameters (10mm, 5mm, or other specifications) are evenly distributed on the side of the air distributor. A blocking plate is installed at the bottom of the air distributor. The infrared level gauges, laser bubble breaker, and air distributor installed at the bottom of the flotation machine's agitator on the phosphate rock flotation cell body are linked. A detailed structural diagram is shown in the figure.

[0037] In practice, the slurry is floated in the phosphate flotation cell. Air is injected into the slurry through an air distributor to form bubbles of various sizes. Hydrophobic mineral particles adhere to the bubbles and rise to form foam. Infrared level gauges at both ends of the phosphate flotation cell scan the foam. When the height of the foam layer is too high, the air distributor automatically reduces the aeration to reduce bubble production. When the foam layer is too low, the air distributor automatically increases the aeration to increase bubble production. During the flotation process, the foam scraped off by the scraper is quickly broken by laser waves in the grooves on both sides, and a small amount of water carries away the floated minerals.
