Description

Technical Field

[0001] This utility model relates to a ring-type dry treatment device for smelting slag. Background Technology

[0002] There are many types of slag after smelting, including iron slag, steel slag, and stainless steel slag. Due to incomplete technology, smelting slag was often rejected by smelters and became a burden. With the advancement of technology, various smelting slags have gradually become valuable resources, turning waste into treasure. After various slag treatment processes, they are reused and, after multiple screenings, are handed over to different application scenarios for processing and utilization. Currently, the main slag treatment processes focus on hot quenching, hot pouring, crushing, screening, and magnetic separation, rarely utilizing the heat energy inherent in the slag itself. Smelting slag has an extremely high calorific value, with liquid slag reaching temperatures of over 1,000 degrees Celsius. Even after crushing, it still retains several hundred degrees Celsius. This high heat energy is simply lost and wasted as it is left to cool. Utility Model Content

[0055] like Figure 7 As shown, a cantilever support is provided on one side of the slewing frame; a slag pan tilter is provided on the cantilever support corresponding to the cooling flap;

[0056] In a preferred embodiment of this utility model, the rotary car frame is divided into a slag dumping area, a uniform spreading area, a slag crushing area and a slag falling area in sequence.

[0057] A cantilever support is provided on one side of the rotary car frame in the slag dumping area; a slag pan tilter is provided on the cantilever support corresponding to the cooling flap;

[0058] One or more cantilever supports are provided on one side of the rotary frame in the evenly spreading area; a leveling roller is provided below the cantilever support corresponding to the cooling flap;

[0059] One or more cantilever supports are provided on one side of the rotary frame in the crushing area; crushing rollers are provided below the cantilever supports corresponding to the cooling flaps;

[0060] Furthermore, guide wheels 7 are provided on the inner and / or outer circumferential surfaces of the slewing frame.

[0061] Work process:

[0062] First, the smelting slag is poured into a slag pan. The slag pan is then lifted by a crane onto the slag pan tilting machine 12 in the slag dumping area. The slag pan tilting machine 12, through electronic control, evenly pours the high-temperature liquid slag onto a ring of cooling flaps 3. The cooling flaps 3 have a load-bearing wheel at the bottom center and move in a ring on the support curved rail 6. The cooling flaps 3 are connected to the rotary frame 2 via a hinge support at the bottom in the forward direction. Driven by the main drive 1 and guided by the center of the guide wheel 6, the rotary frame 2 rotates, which in turn drives the outer ring rotor of the rotary joint center 8 to move, causing the cooling flaps 3 to rotate. The number of cooling flaps 2 in a ring is designed to be fan-shaped and evenly distributed according to process requirements. In this invention, 60 pieces are evenly distributed around a ring, and each cooling flap 2 is connected to the rotary frame 2. The main drive 1 is symmetrically arranged on both sides of the slewing frame 2, while the guide wheels 7, corresponding to the number of each cooling flap 2, are arranged inside the slewing frame 2 to ensure that the slewing frame 2 does not become eccentric during its slewing motion on the load-bearing support rollers 5. The entire slewing frame is connected as a single rotating unit. The entire slewing process, starting from the slag pouring start position, passes through the equalization zone, the slag crushing zone, and the slag dropping zone at the end position.

[0063] When the liquid slag is poured onto the cooling flap 3, it flows and accumulates on the cooling flap 3, forming a shape with a high thickness in the middle and a thin edge. As the rotary frame 2 rotates, the cooling flap 3 with accumulated liquid slag comes to the equalization zone. The equalization zone is equipped with a cantilever flat-laying roller 9. The high-temperature slag with good fluidity is evenly distributed to the outer area of ​​the cooling flap 3 under the roller pressure of the cantilever flat-laying roller 9. In this way, the thickness of the slag on each cooling flap 3 is basically uniform, and the area is maximized.

[0064] When the rotary frame 2 moves the flattened cooling flap 3 to the slag crushing area, the slag has been cooling for a certain period of time, and its surface gradually hardens, especially at the bottom of the slag and the top surface of the cooling flap 3 where it contacts and hardens faster. However, the interior of the slag is still very hot and remains in a fluid state. At this time, the cantilever crushing roller 10 above rotates and crushes the flattened slag by squeezing. The surface of the cantilever crushing roller 10 is welded with irregular cones, similar to a mace structure, which punctures and crushes the flattened slag.

[0065] The rotary carriage 2 continues to rotate. When the cooling tipper 3 reaches the slag discharge area, the curved track causes it to gradually change its tilt angle from a horizontal position under gravity. Reaching a critical point, the tipper 3 suddenly flips over to a vertical position, and under gravity and inertia, the slag on it falls directly into the crushing roller 11 below. Under the strong pressure of the crushing roller 11, the slag is further crushed and transported to other locations for screening and utilization. Throughout the rotary motion, as the slag continues to cool and shrink on the cooling tipper 3, there is displacement between the bottom of the slag and the top plate of the cooling tipper 3, preventing slag adhesion. During the absorption of residual heat from the smelting slag, the speed of the entire rotary carriage 2 can be frequency-controlled. Initially, the speed is faster to ensure the hot slag is quickly poured onto the cooling tipper 3. After pouring, the rotation speed decreases, dynamically adjusted according to the cooling rate and the slag delivery time interval, allowing for slow rotation as well.
