Description

Technical Field

[0001] The utility model relates to the field of iron concentrate processing, and in particular to a deep desulfurization device for iron concentrate. Background Technology

[0002] Iron concentrate, as a crucial raw material in steel production, directly impacts the quality of the final product. However, iron ore naturally contains sulfur, primarily in the form of sulfides such as pyrite. During steelmaking, sulfur reduces the quality of steel, increasing hot brittleness and affecting its mechanical and corrosion resistance. Therefore, effective desulfurization of iron concentrate before it enters the blast furnace or direct reduction process is of paramount importance.

[0003] In existing iron concentrate desulfurization processes, only sulfur-containing air bubbles at the front end of the discharge port can be scraped off. The remaining air bubbles will remain on the surface of the water and need to be manually scraped off by the staff, which will affect subsequent processing.

[0004] Therefore, we need to provide a deep desulfurization device for iron concentrate. Summary of the Invention

[0005] In order to overcome the shortcomings of existing desulfurization devices that can only scrape off the bubbles in the first half of the process, this utility model provides a deep desulfurization device for iron concentrate.

[0006] The technical solution of this utility model is: a deep desulfurization device for iron concentrate, including a reaction frame, a fixed block, a mixer and a crossflow fan. The fixed block is installed on the top of the reaction frame, and the mixer is installed on the fixed block. The stirring rod of the mixer is inside the reaction frame. A crossflow fan is installed on the rear side of the reaction frame. The crossflow fan can blow the air bubbles floating on the water surface to the outlet.

[0007] Furthermore, it also includes a motor and a scraper. A motor is installed on one side of the reaction frame, and a scraper is connected to the output shaft of the motor. The scraper can remove air bubbles floating on the water surface.

[0008] Furthermore, it also includes a fixing plate, a collection frame, a limiting block, a pull rod, and a stop block. Fixing plates are installed on both sides of the reaction frame, and a collection frame is slidably provided between the two fixing plates. A limiting block is installed on the top of the fixing plate, and a pull rod is slidably provided on the limiting block. A stop block is installed at one end of the pull rod.

[0009] Furthermore, it also includes a spring, with the spring sleeved on the pull rod, and the two ends of the spring connected to the limit block and the stop block respectively.

[0010] Furthermore, it also includes a water tank, a water pump, and a water supply pipe. Water tanks are placed on both sides of the reaction frame, and a water pump is installed inside the water tank. A water supply pipe is connected to the outlet of the water pump, with the end of the water supply pipe away from the water pump facing inwards towards the reaction frame.

[0011] Furthermore, it also includes multiple anti-slip sleeves on the pull rod.

[0012] The beneficial effects of this utility model are as follows: 1. By setting up a crossflow fan, the crossflow fan will blow the bubbles after the mineral slurry reaction to the outlet, and then the scraper will rotate to scrape off the bubbles on the surface of the mortar, thus achieving the effect of keeping the mortar surface clean.

[0013] 2. By setting up a collection frame, the rotating scraper will scrape the air bubbles on the surface of the slurry into the collection frame. When the air bubbles in the collection frame reach a certain level, the sulfur-containing air bubbles will be poured out, thus achieving the effect of sulfur collection. Attached Figure Description

Detailed Implementation

[0020] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0021] A deep desulfurization device for iron concentrate, such as Figures 1-5As shown, the system includes a reaction frame 1, a fixing block 2, a mixer 3, a crossflow fan 4, a motor 5, a scraper 6, a fixing plate 7, a collection frame 8, a limiting block 9, a pull rod 10, a stop block 11, a spring 12, a water tank 13, a water pump 14, and a water supply pipe 15. The fixing block 2 is mounted on the top of the reaction frame 1, and the mixer 3 is mounted on the fixing block 2. The stirring rod of the mixer 3 moves inside the reaction frame 1. The crossflow fan 4 is mounted on the rear side of the reaction frame 1. The crossflow fan 4 blows air onto the bubbles floating on the water surface, and the air blown by the crossflow fan 4 pushes the bubbles to the outlet. The motor 5 is mounted on one side of the reaction frame 1, and the scraper 6 is connected to the output shaft of the motor 5. The scraper 6 can scrape off the bubbles blown to the outlet by the crossflow fan 4. The reaction frame 1 has... The fixing plate 7 is installed, and the collection frame 8, which can collect air bubbles, is slidably provided between the two fixing plates 7. The limiting block 9 is installed on the top of the fixing plate 7, and the pull rod 10 is slidably provided on the limiting block 9. The pull rod 10 is provided with multiple anti-slip sleeves, and the stop block 11 is installed at one end of the pull rod 10. The stop block 11 can limit and fix the collection frame 8. The spring 12 is sleeved on the pull rod 10. The spring 12 can reset the stop block 11. The two ends of the spring 12 are respectively connected to the limiting block 9 and the stop block 11. The water tank 13 is placed on both sides of the reaction frame 1. The water pump 14 is installed in the water tank 13. The water outlet of the water pump 14 is connected to the water delivery pipe 15. The end of the water delivery pipe 15 away from the water pump 14 faces the inside of the reaction frame 1.

[0022] When this device is needed, first pour the mixed slurry into the reaction frame 1, then turn on the mixer 3. The mixer 3 will stir the mixed slurry. Then pour in the flotation reagent. After thorough stirring, many bubbles will rise on the surface of the slurry. Turn on the crossflow fan 4. The air blown by the crossflow fan 4 will blow the bubbles to the outlet. Then turn on the motor 5. The output shaft of the motor 5 will rotate, driving the scraper 6 to rotate. The rotation of the scraper 6 will scrape the bubbles on the surface of the slurry into the collection frame 8. When the bubbles in the collection frame 8 have been collected to a certain extent, pull the pull rods 10 on both sides. Pulling the pull rods 10 will compress the spring 12, and at the same time... The baffle 11 will rise. When the baffle 11 is no longer in contact with the fixed plate 7, the collecting frame 8 will be pulled out from the fixed plate 7, and the air bubbles in the collecting frame 8 will be collected. Then the collecting frame 8 will be pushed back into the fixed plate 7. Then the pull rod 10 will be released, and the baffle 11 will be reset under the action of the spring 12. When the slurry in the reaction frame 1 has reacted to a certain extent, one of the water pumps 14 will be turned on. The water pump 14 will pump the water in the water tank 13 into the water pipe 15, and then flow into the reaction frame 1. When the slurry in the reaction frame 1 has reacted completely, the outlet at the back of the reaction frame 1 will be opened to pour out the slurry in the reaction frame 1.
