Description

Technical Field

[0001] The present invention relates to the technical field of steel smelting, and in particular to a system and method for recycling and treating solid waste from steel smelting. Background Art

[0002] Solid waste, namely steel slag, will appear in the steelmaking process. It is composed of various oxides formed by oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts generated by the reaction of these oxides with solvents. Steel slag contains a variety of useful components, including metallic iron, calcium oxide, magnesium oxide, etc., so it can be used as a raw material for steel metallurgy. There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle it in the factory as a smelting solvent, which can not only replace limestone, but also recover a large amount of metallic iron and other useful elements from it; the other is to use it as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers.

[0003] At present, when recycling and reusing solid waste from steel smelting in the market, the steel slag needs to be poured between two crushing rollers for crushing. However, in the specific operation process, due to the large volume of steel slag, it is inconvenient for the crushing roller to crush it, which affects the crushing effect of the steel slag; at the same time, excessive steel slag falls on the crushing roller, which also affects the crushing effect of the steel slag and leads to low overall crushing effect of the steel slag.

[0052] The present invention also discloses a method for recycling and treating solid waste from steel smelting, including a system for recycling and treating solid waste from steel smelting, and further comprising the following steps:

[0053] S1: The steel slag to be crushed is manually dumped into the feed shell 101 by a forklift. At this time, the second baffle 4 closes the space between the feed shell 101 and the extrusion shell 102, and the first baffle 3 closes the space between the extrusion shell 102 and the crushing shell 103;

[0054] S2: Then the main driving component is controlled to work, so that the second driving component drives the second baffle 4 to move, and the second baffle 4 moves into the working box 2. The iron slag in the feed shell 101 falls on the first baffle 3 from the gap after the second baffle 4 is removed. At this time, part of the iron slag is temporarily stored in the extrusion shell 102. Then the third driving component drives the extrusion plate 5 to move, so that the extrusion plate 5 squeezes and breaks the iron slag in the extrusion shell 102. Then the first driving component drives the first baffle 3 to move, so that the first baffle 3 moves into the working box 2. At this time, the iron slag squeezed and broken by the extrusion plate 5 falls into the crushing shell 103;

[0055] S3: The crushing assembly in the crushing shell 103 crushes the iron slag after the initial crushing again, and the crushed iron slag falls from the opening at the lower side of the crushing shell 103, and the staff collects and processes it in a centralized manner.

[0056] Working principle: The steel slag to be crushed is manually dumped into the feed shell 101 by a forklift. At this time, the second baffle plate 4 closes the space between the feed shell 101 and the extrusion shell 102, and the first baffle plate 3 closes the space between the extrusion shell 102 and the crushing shell 103. Then, the main drive assembly is controlled to work, so that the first motor 6 drives the first gear 6011, the second gear 6012 and the third gear 6013 to rotate through the driving rod 601 when the first motor 6 is running. When the driving rod 601 rotates, it drives the second gear 6012 to mesh and rotate with the fifth gear 802. At this time, the gears in the other two groups of drive assemblies are not meshed. The fifth gear 802 drives the second rotating rod 8 to rotate on the second support plate 202. When the second rotating rod 8 rotates, the fifth gear 802 drives the second rotating rod 8 to rotate on the second support plate 202. The two protrusions 801 abut against the inner wall of the second concave hole 401 of the second baffle plate 4, so that the second baffle plate 4 is displaced in the horizontal direction and moves to the working box 2, the feed shell 101 and the extrusion shell 102 are connected, and the steel slag in the feed shell 101 falls on the first baffle plate 3. As the fifth gear 802 meshes and rotates for one circle, the second protrusion 801 pushes the second baffle plate 4 to reset, and the feed shell 101 and the extrusion shell 102 are blocked; then the third driving assembly works, and when the driving rod 601 rotates, it drives the third gear 6013 to mesh and rotate with the sixth gear 903. At this time, the gears in the other two sets of driving assemblies are not meshed, and the sixth gear 903 drives the third rotating rod 9 to rotate on the third support plate 203, and the third rotating rod 9 rotates When the first connecting plate 901 is driven to rotate, the first connecting plate 901 drives the second connecting plate 902 to swing, so that the second connecting plate 902 drives the extrusion plate 5 to move in the extrusion shell 102, and the steel slag in the extrusion shell 102 is extruded and broken; when the sixth gear 903 rotates one circle, the extrusion plate 5 is reset, and the first driving assembly works at this time. When the driving rod 601 rotates, it drives the first gear 6011 to mesh and rotate with the fourth gear 702, and the gears of the other two sets of driving assemblies are not meshed at this time. The fourth gear 702 drives the first rotating rod 7 to rotate on the first supporting plate 201. When the first rotating rod 7 rotates, the first protrusion 701 is pressed against the inner wall of the first concave hole 301 of the first baffle plate 3, so that the first baffle plate 3 is displaced in the horizontal direction. The extrusion shell 102 is connected to the crushing shell 103. After the fourth gear 702 rotates one circle, the first baffle 3 moves back and resets again to separate the extrusion shell 102 from the crushing shell 103. As the main drive component continues to work, the slag is continuously discharged in batches; the extruded and broken slag enters the crushing shell 103 when the first baffle 3 is removed, and the crushing component works to make one of the rotating shafts 1031 at the output end of the second motor 14 rotate, and the moving gear 1032 on the rotating shaft 1031 meshes with the moving gear 1032 on the other rotating shaft 1031, so that the two rotating shafts 1031 rotate relative to each other, and then the crushing rollers 1033 on the two rotating shafts 1031 crush the slag.

At this time, the second baffle plate (4) closes the space between the feed shell (101) and the extrusion shell (102), and the first baffle plate (3) closes the space between the extrusion shell (102) and the crushing shell (103). Then, the main drive assembly is controlled to operate so that when the first motor (6) is running, the first gear (6011), the second gear (6012) and the third gear (6013) are driven to rotate through the drive rod (601). When the drive rod (601) rotates, the second gear (6012) is driven to mesh with the fifth gear (802) and rotate. At this time, the gears in the other two groups of drive assemblies are not meshed, and the fifth gear (802) is engaged. The wheel (802) drives the second rotating rod (8) to rotate on the second support plate (202). When the second rotating rod (8) rotates, the second protrusion (801) abuts against the inner wall of the second concave hole (401) of the second baffle (4), so that the second baffle (4) is displaced in the horizontal direction and moves toward the working box (2). The feed shell (101) and the extrusion shell (102) are connected, and the steel slag in the feed shell (101) falls onto the first baffle (3). As the fifth gear (802) meshes and rotates one circle, the second protrusion (801) pushes the second baffle (4) to reset, thereby blocking the feed shell (101) and the extrusion shell (102). Then the third driving component works, and when the driving rod (601) rotates, The third gear (6013) is driven to mesh with the sixth gear (903) and rotate. At this time, the gears in the other two groups of driving components are not meshed. The sixth gear (903) drives the third rotating rod (9) to rotate on the third support plate (203). When the third rotating rod (9) rotates, it drives the first connecting plate (901) to rotate. The first connecting plate (901) drives the second connecting plate (902) to swing, so that the second connecting plate (902) drives the extrusion plate (5) to move in the extrusion shell (102), and the steel slag in the extrusion shell (102) is extruded and broken. When the sixth gear (903) rotates one circle, the extrusion plate (5) is reset. At this time, the first driving component is working. When the driving rod (601) rotates, it drives the first gear ( The first gear (6011) meshes with the fourth gear (702) and rotates. The gears of the other two sets of driving components are not meshed at this time. The fourth gear (702) drives the first rotating rod (7) to rotate on the first support plate (201). When the first rotating rod (7) rotates, the first protrusion (701) abuts against the inner wall of the first concave hole (301) of the first baffle plate (3), so that the first baffle plate (3) moves in the horizontal direction, so that the extrusion shell (102) and the crushing shell (103) are connected. After the fourth gear (702) rotates one circle, the first baffle plate (3) moves back again to reset and separate the extrusion shell (102) and the crushing shell (103). As the main driving component continues to work, the slag is continuously discharged in batches.

The iron slag in the feeding shell (101) falls onto the first baffle (3) from the gap after the second baffle (4) is removed. At this time, part of the iron slag is temporarily stored in the extrusion shell (102). Then, the third driving component drives the extrusion plate (5) to move, so that the extrusion plate (5) squeezes and breaks the iron slag in the extrusion shell (102). Then, the first driving component drives the first baffle (3) to move, so that the first baffle (3) moves into the working box (2). At this time, the iron slag squeezed and broken by the extrusion plate (5) falls into the crushing shell (103); S3: The crushing assembly in the crushing shell (103) crushes the iron slag after the initial crushing again, and the crushed iron slag falls from the opening at the lower side of the crushing shell (103), and the staff collects and processes it in a centralized manner.
