Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical waste sorting, and particularly to equipment for sorting metallurgical waste. Background Art

[0002] When sorting metallurgical waste, flotation is often used for sorting, and metal particles in the metallurgical waste are recovered by flotation for subsequent utilization.

[0003] In the use of existing flotation equipment, it is inconvenient to control the size of metal particles in metallurgical waste. When the sizes of metal particles are inconsistent, the particles with too large size have a large gravity and are easy to fall off, while the particles with too small size are easy to agglomerate, making the flotation complex. In addition, the size of flotation bubbles will directly affect the flotation efficiency. It is inconvenient to adjust the size of flotation bubbles in existing flotation equipment, and it is difficult to meet different usage requirements. Therefore, in view of the above situation, there is an urgent need to develop equipment for sorting metallurgical waste that is convenient for controlling the size of metal particles, convenient for adjusting the size of bubbles, and has higher flotation efficiency, so as to overcome the deficiencies in current practical applications and meet the current needs.

The grinding box 2 is fixedly installed above the flotation water tank 1. One side of the grinding box 2 is fixedly provided with a feed port 201. A grinding mechanism 3 extending into its interior is installed at the top of the grinding box 2. The screening mesh 4 is fixedly installed at the bottom of the grinding box 2. The mesh aperture on the screening mesh 4 is 0.1 mm, so as to screen the metallurgical waste powder to 0.1 mm. The adjustable bubble emission mechanism 5 is arranged on the ground and extends to the inner bottom end of the flotation water tank 1. The floating material collection mechanism 6 is installed on the left side inside the flotation water tank 1. A collection box 7 is fixedly installed on the left side of the flotation water tank 1. A stirring and mixing mechanism 8 extending into its interior is installed at the bottom of the flotation water tank 1. During use, first add water flow and flotation agents into the flotation water tank 1, then add metallurgical waste into the grinding box 2 from the feed port 201. Grind the metallurgical waste through the grinding mechanism 3 and screen it through the screening mesh 4, so that the diameter of the waste falling into the flotation water tank 1 is 0.1 mm, in order to improve the subsequent flotation efficiency. The metal particles in the waste residue have hydrophobicity under the action of the flotation agents. Then, inject bubbles into the water flow through the adjustable bubble emission mechanism 5, and stir the water flow through the stirring and mixing mechanism 8, so that the bubbles are in full contact with the metal particles in the waste residue. The metal particles rise to the water surface with the bubbles, and the floating material collection mechanism 6 pushes the metal particles on the water surface into the collection box 7 for collection.

[0031] A drain pipe 101 is installed at the lower end of the flotation water tank 1, and a first valve 102 is installed on the drain pipe 101. After the flotation is over, open the first valve 102 to drain the waste water.

[0032] The grinding mechanism 3 includes: a first motor 301, a large grinding roller 302, a first gear 303, a small grinding roller 304, and a second gear 305.

During use, first close the second valve 506 and open the third valve 507. Use the diaphragm air pump 501 to evacuate or inflate the elastic airbag column 508, so as to adjust the degree of inflation of the elastic airbag column 508. Different degrees of inflation of the elastic airbag column 508 result in different sizes of the gaps through which air can escape on the air outlet nozzle 504, thereby adjusting the size of the bubbles discharged from the air outlet nozzle 504. After adjustment, open the second valve 506 and close the third valve 507. Use the diaphragm air pump 501 to inflate the first conduit 503 and the air outlet nozzle 504. The air flow is discharged from the outlet of the air outlet nozzle 504, and the air flow forms bubbles in the water.

[0034] The floating material collection mechanism 6 includes: a second motor 601, a third gear 602, a fourth gear 603, a transmission shaft 604, and a dial 605. The second motor 601 is fixed to the outside of the flotation water tank 1. A third gear 602 is fixed to the output shaft of the second motor 601.

Push the metal floating on the water surface into the collection box 7 for collection through the dial 605.

[0035] The stirring and mixing mechanism 8 includes: a stirring shaft 801, a synchronous pulley 802, a synchronous belt 803, and a third motor 804. Two stirring shafts 801 are rotatably connected in the flotation water tank 1. A synchronous pulley 802 is fixed to the lower end of each stirring shaft 801. The two synchronous pulleys 802 are drivingly connected by a synchronous belt 803. The third motor 804 is fixed to the ground, and the output shaft of the third motor 804 is fixed to one of the stirring shafts 801. During use, the third motor 804 drives the stirring shaft 801 to rotate, and the stirring shaft 801 stirs the water in the flotation water tank 1.

[0036] A PLC controller 9 is installed on the side of the flotation water tank 1. The first valve 102, the first motor 301, the diaphragm air pump 501, the second valve 506, the third valve 507, the second motor 601, and the third motor 804 are respectively electrically connected to the PLC controller 9 for convenient control.

[0037] Working principle: When the sorting and metallurgical waste equipment is in use, first, water flow and a flotation agent are added into the flotation water tank 1, and then the metallurgical waste is added into the grinding box 2 from the feed port 201. The first motor 301 drives the large grinding roller 302 and the first gear 303 to rotate. The first gear 303 drives the second gear 305 and the small grinding roller 304 to rotate. The large grinding roller 302 and the small grinding roller 304 cooperate to grind the waste residue. The waste residue is screened by the screening mesh 4 so that the diameter of the waste falling into the flotation water tank 1 is 0.1 mm, which is convenient for subsequent flotation. Then, the third motor 804 drives the stirring shaft 801 to rotate, and the stirring shaft 801 stirs the water in the flotation water tank 1, so that the flotation agent fully contacts the metal particles in the waste residue. The metal particles in the waste residue become hydrophobic under the action of the flotation agent. Then, the second valve 506 is closed and the third valve 507 is opened. The diaphragm air pump 501 pumps air into or out of the elastic airbag column 508, thereby adjusting the degree of expansion of the elastic airbag column 508. Different degrees of expansion of the elastic airbag column 508 result in different sizes of the gaps through which air can escape on the air outlet nozzle 504, thereby adjusting the size of the bubbles discharged from the air outlet nozzle 504. After adjustment, the second valve 506 is opened and the third valve 507 is closed. The diaphragm air pump 501 fills the first conduit 503 and the air outlet nozzle 504 with air. The air flow is discharged from the outlet of the air outlet nozzle 504, and the air flow forms bubbles in the water. Under the stirring action of the stirring and mixing mechanism 8, the bubbles fully contact the metal particles. The metal particles rise to the water surface with the bubbles, and the floating material collection mechanism 6 pushes the metal particles on the water surface into the collection box 7 for collection.
