Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of iron oxide purification, and more specifically, to a steam flotation apparatus for iron oxide purification. Background Technology
[0002] In the purification process of iron oxide, steam flotation is widely used because it can efficiently separate impurities from minerals. Its principle is that microbubbles generated by steam adsorb impurity particles and carry them to the liquid surface to form froth, thereby separating iron oxide from impurities. However, existing steam flotation devices have significant drawbacks in the froth and floating impurity removal process, severely limiting purification efficiency and purity.
[0003] Traditional flotation equipment relies heavily on manual skimming or settling overflow for foam removal. Manual cleaning requires frequent interruptions to the flotation process, increasing the processing time per batch and making it difficult to completely remove fine floating impurities from the liquid surface, resulting in high impurity residue and directly affecting the purity of the finished iron oxide product. The settling overflow method, due to difficulties in flow rate control, easily causes some purified iron oxide particles to be discharged along with the foam, resulting in material loss.
[0004] Furthermore, the scum that accumulates over time can form sticky clumps as the temperature drops, not only increasing the difficulty of cleaning but also potentially clogging steam pipes and increasing equipment maintenance costs. In continuous production scenarios, this cleaning lag necessitates a production line shutdown for maintenance, shortening the effective operating time. Therefore, developing a steam flotation device that can quickly remove scum and floating impurities has become an urgent need to improve iron oxide purification efficiency and reduce production costs. Utility Model Content

[0024] like Figures 1-4 As shown, it illustrates a steam flotation apparatus for purifying iron oxide in one embodiment of this disclosure, comprising: The processing box 1 and the inclined feeding platform 2 are arranged on one side of the top of the processing box 1; Aeration flotation component 3 is disposed in the treatment tank 1; Cleaning component 4 is disposed on the top of the processing box 1; The aerated flotation component 3 includes a side opening 3-1, which is located on the front of the treatment tank 1. A material box 3-2 is rotatably connected to the side opening 3-1 via a pin. The material box 3-2 is sealed to the inner surface of the side opening 3-1. An air inlet mesh 3-3 is provided at the bottom of the treatment tank 1. Several aeration chambers 3-4 are provided at the bottom of the treatment tank 1. A main pipe 3-5 is provided inside the treatment tank 1. Several connecting pipes 3-6 are connected to the aeration chambers 3-4 via the main pipe 3-5. Aeration ports 3-7 are provided at both ends of the top of the aeration chambers 3-4. A packing spray pipe 3-8 is provided at the top of the treatment tank 1. The packing spray pipe 3-8 is located above the inclined feeding platform 2. Telescopic hydraulic cylinders 3-9 are rotatably connected to both sides of the treatment tank 1 via pins. The output end of the telescopic hydraulic cylinder 3-9 is rotatably connected to the outer surface of the material box 3-2 via a pin.
[0025] In some examples, to achieve uniform aeration and rapid discharge during the iron oxide purification process, an aeration flotation component 3 is designed. This component includes a side opening 3-1 on the front of the treatment tank 1. A material box 3-2 is rotatably connected by a pin and sealed to the inner surface of the side opening 3-1 to ensure stable internal air pressure during aeration. Steam or gas can be introduced through the air inlet mesh 3-3 at the bottom of the treatment tank 1. Several aeration chambers 3-4 are evenly distributed at the bottom. The main pipe 3-5 is connected to the aeration chambers 3-4 through several connecting pipes 3-6, forming a gas delivery network. Aeration ports 3-7 are symmetrically arranged at both ends of the top of the aeration chambers 3-4, allowing for uniform release of gas into the liquid material within the treatment tank 1. The packing spray pipe 3-8 at the top of the treatment tank 1 is located above the inclined feed platform 2, allowing for the spraying of flotation reagents onto the incoming material. The telescopic hydraulic cylinders 3-9 on both sides of the processing box 1 are rotatably connected to the outer surfaces of the processing box 1 and the material box 3-2 respectively via pins, which can drive the material box 3-2 to rotate around the pins. During operation, steam or gas enters the main pipe 3-5 through the air inlet mesh 3-3, and is distributed to each aeration chamber 3-4 through the connecting pipe 3-6. It then escapes evenly from the aeration port 3-7, forming a large number of bubbles. These bubbles combine with impurities in the liquid to form foam, achieving the separation of iron oxide from impurities. After purification, the telescopic hydraulic cylinder 3-9 extends, pushing the material box 3-2 to rotate outwards. The material box 3-2 rotates around the pivot to an inclined position, allowing all internal material to be quickly discharged, avoiding residue. The multi-point distribution of aeration chambers 3-4 and aeration ports 3-7 ensures uniform gas diffusion, improving flotation efficiency. The sealed material box 3-2 prevents air leakage, ensuring stable aeration. The rotating structure of the material box 3-2 driven by the telescopic hydraulic cylinder 3-9 enables rapid discharge, shortening the operation cycle. The filler spray pipe 3-8, in conjunction with the inclined feed platform 2, ensures thorough mixing of the reagent and material, enhancing the flotation effect. This component provides a stable flotation environment for iron oxide purification through uniform aeration and efficient discharge design, thereby improving purification efficiency and material utilization.
[0026] like Figures 1-4 As shown in the figure, the cleaning component 4 in this embodiment includes a pair of rotating disks 4-1, which are vertically rotatably connected to both sides of the processing box 1. The rotating disks 4-1 are driven to rotate by electricity. The surface of the rotating disks 4-1 has a circular opening 4-2. A cylinder 4-3 is connected between the rotating disks 4-1. The surface of the cylinder 4-3 has a collection port 4-4. A plurality of filter plates 4-5 are provided on the surface of the cylinder 4-3. The filter plates 4-5 are fixedly connected at an inclined angle. A collection hopper 4-6 is provided inside the processing box 1. The collection hopper 4-6 extends laterally through the circular opening 4-2 and the interior of the cylinder 4-3. A discharge port 4-7 is provided on one side of the processing box 1. A pusher auger 4-8 driven to rotate by electricity is provided inside the collection hopper 4-6.
[0027] In some examples, to ensure continuous removal of scum and impurities and maintain the continuity of iron oxide purification, a cleaning component 4 is designed. This component includes two rotating disks 4-1 on either side of the processing tank 1, which are vertically connected and driven synchronously by a motor. A circular opening 4-2 on the surface provides a channel for a collection hopper 4-6. A cylindrical cylinder 4-3 connected between them rotates synchronously with the rotating disks 4-1, and its collection opening 4-4 captures scum and impurities. Several filter plates 4-5 on the surface of the cylinder 4-3 are fixed at an inclined angle to intercept impurities and guide them into the collection opening 4-4. The collection hopper 4-6 inside the processing tank 1 extends laterally through the circular opening 4-2 and the interior of the cylinder 4-3, with one end connected to a discharge outlet 4-7 on one side of the processing tank 1. A pusher auger 4-8 inside is driven by a motor to rotate and transport the collected impurities. During operation, the rotating disk 4-1 drives the cylinder 4-3 to rotate, and the filter plate 4-5 rotates with the cylinder 4-3, scraping the foam and impurities on the surface of the treatment tank 1 to the collection port 4-4. The impurities enter the cylinder 4-3 through the collection port 4-4 and fall into the collection hopper 4-6. The rotating auger 4-8 pushes the impurities in the collection hopper 4-6 along the hopper body to the discharge port 4-7 for discharge. The entire process is synchronized with the aeration flotation, achieving continuous cleaning. The rotating cylinder 4-3 and filter plate 4-5 expand the cleaning range, ensuring that foam is collected without dead corners; the inclined filter plate 4-5 uses gravity to assist impurities to enter the collection port 4-4, improving collection efficiency; the cooperation between the collection hopper 4-6 and the auger 4-8 achieves continuous impurity transport and avoids accumulation; the stable rotation of the rotating disk 4-1 ensures continuous cleaning without interfering with the flotation process. This component, through its dynamic cleaning design, continuously removes foam and impurities, maintains a stable feed environment, and ensures efficient iron oxide purification.
[0028] For example, such as Figure 2 As shown, a central cover 5 is provided on one side of the processing box 1, and the central cover 5 is located at the bottom of the discharge port 4-7.
[0029] In some examples, the collection hood 5 on one side of the treatment tank 1 is located at the bottom of the discharge port 4-7 and has a funnel-shaped structure. It can collect the scum and impurities discharged from the discharge port 4-7, preventing impurities from scattering and polluting the surrounding environment. The funnel design of the collection hood 5 can guide impurities into subsequent treatment equipment, reducing the workload of manual cleaning, while preventing impurities from accumulating and clogging near the discharge port 4-7, ensuring the continuous and stable operation of the cleaning component 4, and improving the environmental friendliness and ease of operation of the device.
[0030] For example, such as Figure 3 As shown, the material box 3-2 can be rotated outward by more than 90° driven by the telescopic hydraulic cylinder 3-9.
[0031] In some examples, the material bin 3-2 can be tilted outward by more than 90° via a telescopic hydraulic cylinder 3-9, allowing the opening of the material bin 3-2 to face completely downward. This large-angle tilting allows the material inside the material bin 3-2 to be completely discharged by gravity, preventing residual material from affecting the next purification operation. At the same time, tilting by more than 90° facilitates cleaning and maintenance of the inside of the material bin 3-2, ensuring the cleanliness of the material bin 3-2, preventing cross-contamination between different batches of material, and ensuring the purity of the iron oxide purification.
[0032] In actual use: the material enters the material box 3-2 of the processing tank 1 through the inclined feeding platform 2. The filler spray pipe 3-8 sprays the agent onto the material. Steam enters the main pipe 3-5 through the air inlet mesh 3-3, and is distributed to the aeration chamber 3-4 through the connecting pipe 3-6. It escapes from the aeration port 3-7 to form bubbles, which adsorb impurities and form foam. At the same time, the rotating disc 4-1 drives the cylinder 4-3 to rotate, and the filter plate 4-5 scrapes the foam to the collection port 4-4. Impurities enter the cylinder 4-3 and fall into the collection hopper 4-6. The screw conveyor 4-8 pushes the impurities from the discharge port 4-7 to the collection hood 5. After flotation is completed, the telescopic hydraulic cylinder 3-9 drives the material box 3-2 to flip outward, discharging the purified iron oxide. The entire process is continuous and requires no interruption for cleaning.
