Description

Technical Field

[0001] This utility model relates to a flotation device for sintering machine head ash, belonging to the field of steel production technology. Background Technology

[0002] Sintering machine head ash is a solid waste generated during steel production. Because it contains heavy metals and other harmful substances, direct discharge will pollute the environment. Therefore, comprehensive utilization and treatment of sintering machine head ash is particularly important. Flotation, as a physical separation technology, plays a crucial role in the treatment of sintering machine head ash. Flotation treatment of sintering machine head ash not only contributes to environmental protection but also improves the comprehensive utilization efficiency of resources, bringing dual economic and social benefits. Flotation of sintering machine head ash requires the use of a flotation device. However, existing flotation devices discharge concentrate slurry and tailings slurry from the same outlet, easily leading to incomplete flotation and affecting subsequent processing. Furthermore, uneven mixing of flotation reagents and sintering machine head ash slurry during flotation results in waste of flotation reagents or reduced flotation efficiency. Therefore, this utility model is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6As shown, a flotation device for sintering machine head ash includes a flotation tank 1. Partitions 2 are uniformly fixedly installed inside the flotation tank 1. A stirring assembly 3 is installed inside the flotation tank 1. Screws 4 are installed at both the upper and lower ends of the flotation tank 1, located at the upper and lower ends of the partitions 2. A movable feeding assembly 5 is installed at the upper end of the flotation tank 1, connected to an external flotation reagent tank. Bubbling assemblies 6 are installed on both sides of the lower end of the flotation tank 1, connected to an external air pump. The flotation tank 1 is connected to a discharge pipe 7 installed on both sides of its exterior. The discharge pipe 7 is located below one end of the auger 4. During use, the mobile feeding component 5 sprays the flotation reagent evenly into the flotation tank 1. At the same time, the stirring component 3 can stir the flotation reagent and the raw pulp evenly, thereby improving the uniformity of mixing. Then, the bubble-expelling component 6 introduces air bubbles into the flotation tank 1, thereby completing the separation. The auger 4 can move the upper and lower materials to both ends, and then discharge them through the discharge pipe 7 to complete the flotation.

[0021] Support columns 8 are fixedly installed at the four corners of the lower end of the flotation tank 1. Anti-slip rubber pads are fixedly installed at the lower end of each support column 8. When in use, the structure is first placed at the location of use through the support columns 8.

[0022] The stirring assembly 3 includes a control motor 301, which is fixedly installed on the outside of the flotation tank 1. A rotating shaft 302 is fixedly installed at the output end of the control motor 301. The other end of the rotating shaft 302 passes through the partition 2 and is rotatably connected to one end inside the flotation tank 1. Stirring rods 303 are evenly fixedly installed on the rotating shaft 302. The stirring rods 303 are arranged at intervals with the partition 2. In use, sintering head ash and water are put into the flotation tank 1. Then, the control motor 301 drives the rotating shaft 302 and the stirring rods 303 to rotate, thereby mixing the sintering head ash and water into a slurry.

[0023] The mobile feeding assembly 5 includes a slide rail 501, which is fixedly installed on both sides of the upper end of the flotation tank 1. A reciprocating motor 502 is fixedly installed on one end of the slide rail 501. A movable threaded rod 503 is rotatably engaged inside the slide rail 501. One end of the movable threaded rod 503 is fixedly connected to the output end of the reciprocating motor 502. A movable block 504 is slidably engaged in the slide rail 501. The lower part of the movable block 504 is threadedly sleeved on the movable threaded rod 503. A dispensing tube 505 is fixedly installed on one side of the upper part of the movable block 504. The dispensing tube 505 is located above the flotation tank 1, with the middle of the upper end of the dispensing tube 505... A fixed delivery hose 506 is installed, with the other end of the delivery hose 506 connected to an external flotation reagent tank. Discharge nozzles 507 are evenly fixedly installed at the lower end of the dispensing pipe 505. During use, the flotation reagent can be passed into the dispensing pipe 505 through the delivery hose 506 and sprayed out through the discharge nozzles 507. At the same time, the reciprocating motor 502 drives the moving threaded rod 503 to rotate back and forth, thereby driving the moving block 504 to move back and forth, so that the dispensing pipe 505 can move back and forth, adjusting the spraying position and improving the uniformity of flotation reagent spraying. During spraying, the stirring component 3 mixes the flotation reagent and the raw pulp evenly.

[0024] The foaming assembly 6 includes a connecting pipe 601, which is fixedly installed on both sides of the lower end of the flotation tank 1. An air inlet pipe 602 is fixedly installed in the middle of one side of the connecting pipe 601. The other end of the air inlet pipe 602 passes through the flotation tank 1 and is connected to an external air pump. One-way foaming valves 603 are evenly fixedly installed on the other side of the connecting pipe 601. In use, the external air pump pumps gas into the connecting pipe 601 through the air inlet pipe 602, and then foaming is completed through the one-way foaming valve 603. Lead-containing minerals will float to the surface under the action of bubbles, forming a foamy concentrate slurry, while lead-free minerals remain in the tailings slurry.

[0025] Both ends of the auger 4 are rotatably clamped to the side wall of the flotation tank 1, and slow motors 9 are fixedly installed on both sides of the flotation tank 1. The output end of the slow motor 9 is fixedly connected to one end of the auger 4. A shut-off valve 10 is fixedly installed on the discharge pipe 7. In use, the slow motor 9 drives the auger 4 to rotate, thereby moving the frothy tailings slurry and tailings slurry to the diagonal of the flotation tank 1. Then the tailings slurry is discharged through the discharge pipe 7 first. After it is completely discharged, the tailings slurry is discharged through another discharge pipe 7, thus completing the flotation.

[0026] In use, this invention is first placed at the location using the support column 8. Then, sintering machine head ash and water are placed into the flotation tank 1. Subsequently, the motor 301 drives the rotating shaft 302 and stirring rod 303 to rotate, thus mixing the sintering machine head ash and water into a slurry. The flotation reagent is then introduced into the dispensing pipe 505 through the delivery hose 506 and sprayed out through the dispensing nozzle 507. Simultaneously, the reciprocating motor 502 drives the moving threaded rod 503 to reciprocate, thereby causing the moving block 504 to move reciprocally, allowing the dispensing pipe 505 to move back and forth, adjusting the spraying position and improving the spraying efficiency of the flotation reagent. The uniformity of the flotation reagent and the raw slurry is ensured during spraying. The mixing component 3 mixes the flotation reagent and the raw slurry evenly. Then, the external air pump pumps the gas into the connecting pipe 601 through the air inlet pipe 602. Subsequently, the one-way bubble valve 603 completes the bubble discharge. The lead-containing minerals will float to the surface under the action of the bubbles, forming a foamy concentrate slurry, while the lead-free minerals remain in the tailings slurry. Then, the slow motor 9 drives the screw conveyor 4 to rotate, thereby moving the foamy tailings slurry and the tailings slurry to the diagonal of the flotation box 1. Then, the tailings slurry is first discharged through the discharge pipe 7. After it is completely discharged, the tailings slurry is discharged through another discharge pipe 7, thus completing the flotation.
