Description

Technical Field

[0002] Coal slag is a kind of industrial solid waste, which is the waste slag discharged from coal-fired power plants, industrial and civil boilers and other equipment. The mineral composition of coal slag mainly includes: calcium feldspar, quartz, mullite, magnetite and pyrite, a large amount of silicon-containing glass (Al2O3·2Si02), and active SiO2, active Al2O3 and a small amount of unburned coal. At present, this kind of waste slag is widely distributed in my country, and the utilization amount is far less than the discharge amount. When it is abandoned and piled up, it can also release sulfur-containing gas to pollute the atmosphere and harm the environment. These coal slag wastes are recyclable dry garbage and can be reused. The uses of coal slag include making masonry mortar and wall materials, as cement mixed materials and as lightweight concrete aggregates.

[0039] How it works

[0040] The staff puts the coal slag into the first classification cylinder 10 through the feeding funnel 11. The coal slag entering the first classification cylinder 10 falls onto the conical filter cylinder 19. The first motor 33 starts to drive the transmission disk 34 to rotate forward. The rotation of the transmission disk 34 drives the spline keypad 35 to rotate. The rotation of the spline keypad 35 drives the first rotating column 18 to rotate through the spline. The rotation of the first rotating column 18 drives the two sliders 32 to rotate forward. The two sliders 32 rotate forward and move downward in the spiral chute 31, driving the first rotating column 18 to move downward. The first motor 33 rotates forward and reverse alternately to make the first rotating column 18 cooperate with the spiral chute 31 to move up and down in the conical block 16.

[0041] The rotation of the first rotating column 18 drives the conical filter cartridge 19 to rotate, and the rotation of the conical filter cartridge 19 moves the coal slag in the circumferential direction. The coal slag is filtered through multiple filter holes 20, and large particles are guided by the inclined wall of the conical filter cartridge 19 through the through hole 24 to enter the conical cylinder 12; when the conical filter cartridge 19 rotates upward, the filter holes 20 at the lower part of the conical filter cartridge 19 are blocked by the protrusions 23 and the inclined plate 22, and the strong magnetic block 29 is located in the conical block 16, so that the magnetic force of the annular magnetic block 30 is strengthened; small particles are filtered through the filter holes 20 at the upper part of the conical filter cartridge 19 and fall onto the annular magnetic block 30, and the iron ore is attracted by the annular magnetic block 30, and the remaining particles move outward through the inclined surface of the annular magnetic block 30 and fall onto the first inclined guide block 43, and are guided by the first inclined guide block 43 through the second discharge port 42 to enter the second classification cylinder 13.

[0042] When the conical filter cartridge 19 rotates downward, the first rotating column 18 moves downward through the connecting block 28 to drive the strong magnetic block 29 to move downward into the fixed column 17, so that the magnetic force of the annular magnetic block 30 is reduced, and the magnetic field generated by the strong magnetic block 29 moves to the bottom of the conical block 16. The conical filter cartridge 19 moves downward and separates from the inclined plate 22, so that the filter hole 20 at the bottom of the conical filter cartridge 19 is opened, and the particles on the upper side of the conical filter cartridge 19 fall through the filter hole 20 at the bottom of the conical filter cartridge 19, and the magnetic field generated by the strong magnetic block 29 The iron ore is attracted to move inward and fall into the collecting cylinder 40, and the conical filter cylinder 19 moves downward to drive the T-shaped block 36 to contact the annular magnetic block 30. The T-shaped block 36 is squeezed and slides in the conical filter cylinder 19, and the solution in the hydraulic chamber 38 squeezes the pointed blocks 39 on both sides to slide out to clean the filter holes 20 on the upper part of the conical filter cylinder 19; the T-shaped block 36 rotates to brush the iron ore on the annular magnetic block 30, and then the iron ore is attracted to move inward and fall into the collecting cylinder 40 through the magnetic field generated by the strong magnetic block 29.

[0043] The large particles in the conical barrel 12 are guided by the second inclined guide block 52 to pass through the first discharge port 41 and enter the third classification barrel 14. The second motor 44 is started to drive the second rotating column 45 to rotate. The rotation of the second rotating column 45 drives the spiral plate 46 to rotate. The rotation of the spiral plate 46 causes the large particles to move downward evenly. The large particles fall onto the inclined guide plate 47, and are guided by the inclined guide plate 47 to move to the inclined filter plate 48. The small particles carried by the large particles are filtered by the inclined filter plate 48 and fall into the middle storage chamber 60 through the fourth discharge port 50 for storage. The large particles pass through the inclined filter plate 48 and then enter the storage chamber 60 on the rear side through the third discharge port 49 for storage.

[0044] The small particles entering the second classification cylinder 13 fall into the funnel 51, and are guided by the funnel 51 to the middle and fall down. The third motor 53 is started to drive the rotating sleeve 54 to rotate counterclockwise. The rotating sleeve 54 rotates to drive the six rotating magnetic rods 55 to rotate. The rotating magnetic rods 55 rotate to the side of the positive magnetic block 61 to strengthen the magnetic force to adsorb the iron ore in the small particles on the rotating magnetic rods 55. The small particles are beaten to the side of the fifth discharge port 56 through the rotating magnetic rods 55, and fall into the middle storage chamber 60 through the fifth discharge port 56; the rotating magnetic rods 55 rotate to the side of the negative magnetic block 62 to generate a repulsive force to remove the iron ore on the rotating magnetic rods 55 to the side of the sixth discharge port 57, and the iron ore falls into the front storage chamber 60 through the rotating sleeve 54 for storage.
