Abstract
Description
Technical Field
[0001] This utility model relates to the field of iron and steel smelting technology, and in particular to a slag pan residue crushing device. Background Technology
[0002] In the steel smelting process, high-temperature steel slag at 1400-1600℃ is poured into a slag pan and must undergo natural cooling to room temperature before proceeding to subsequent processing stages. During this process, due to the characteristics of the smelting process, a small amount of molten steel accompanying the slag will naturally settle at the bottom of the slag pan due to its density advantage. When the temperature of the molten steel and slag mixture drops below 1200℃, the steel slag and molten steel will form a high-strength solidified mixture at the bottom of the slag pan. This phenomenon makes it difficult to completely separate the solidified mixture from the slag pan during subsequent transfer and dumping operations. This not only significantly reduces the efficiency of steel slag processing but also easily leads to problems such as slag pan residue accumulation and shortened slag pan lifespan. This seriously restricts the continuity of the smelting production line and equipment turnover efficiency, becoming a key bottleneck affecting production efficiency and cost control.
[0003] Traditional slag pan residue treatment often uses blasting machines, which has drawbacks such as low processing efficiency, high energy consumption and cost, and significant noise pollution. Utility Model Content
[0004] The purpose of this utility model is to provide a slag pan residue crushing device. Based on the principle of mechanical balance, the crushing device converts the weight of the slag pan into the unlocking power source of the breaker hammer. It can efficiently crush the residue in the slag pan without the need for additional energy drive. It has a simple structure, low cost, and is durable. It greatly reduces manual intervention and lowers the labor intensity of personnel.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A slag pan residue crushing device includes an overhead crane, a lifting device, and a breaker hammer. The lifting device is connected to the overhead crane via a chain, and the breaker hammer is suspended on the lifting device. The overhead crane can lift the breaker hammer through the lifting device. After the overhead crane lifts the breaker hammer to a predetermined height, the breaker hammer can automatically unlock from the lifting device, and the breaker hammer falls into the slag pan, thereby crushing the residue in the slag pan.
[0007] Furthermore, in the aforementioned slag pan residue crushing device, the lifting device includes a lifting handle and a lifting hook, the lifting handle and the lifting hook being an integral structure, with one end of the lifting handle connected to one end of the lifting hook.
[0008] Furthermore, in the aforementioned slag pan residue crushing device, a through hole is provided in the middle of the lifting handle, and the lower end of the chain is connected to the lifting device through the through hole.
[0009] Furthermore, in the aforementioned slag pan residue crushing device, the axis of the hook is arc-shaped, the arc angle of the hook is 45°, and the arc length is 15cm.
[0010] Furthermore, the aforementioned slag pan residue crushing device also includes a wire rope, with a positioning hole at the other end of the lifting handle and a lifting lug on the slag pan; one end of the wire rope is connected to the lifting lug, and the other end of the wire rope is connected to the lifting handle through the positioning hole.
[0011] Furthermore, in the aforementioned slag pan residue crushing device, the breaker hammer has a truncated pyramidal structure, and a lifting ring is provided on the small end of the breaker hammer. The hook engages with the lifting ring. After the lifting device lifts the breaker hammer to a predetermined height, the wire rope is straightened. Under the tension of the wire rope, the lifting device rotates around the connection between the chain and the through hole. When the lifting device rotates, the breaker hammer can be disengaged from the hook, thus achieving automatic unlocking between the breaker hammer and the lifting device.
[0012] Furthermore, in the aforementioned slag pan residue crushing device, the mass of the breaker hammer is 50kg to 100kg.
[0013] Furthermore, in the aforementioned slag pan residual slag crushing device, the overhead crane can lift the breaker hammer to a height of 10m.
[0014] Analysis reveals that this utility model discloses a slag pan residue crushing device. This device features a simple structure and convenient, efficient operation. Operators only need to precisely engage the lifting device with the lifting ring of the breaker hammer to quickly complete the lifting preparation, significantly shortening preparation time and greatly improving operational convenience. When the crane lifts the breaker hammer to the preset height, the lifting device automatically unlocks, allowing the breaker hammer to fall freely under gravity, precisely striking the residue in the slag pan and efficiently completing the crushing operation without secondary manual intervention, ensuring the continuity and safety of the operation process. This crushing device, through its automatic unlocking design between the breaker hammer and the lifting device, minimizes manual intervention, effectively avoiding safety risks such as high-altitude operations and heavy object collisions in traditional manual operations. Simultaneously, it significantly reduces the labor intensity of operators, improves operational comfort and efficiency, and provides a solid guarantee for safe production. Attached Figure Description

[0022] The accompanying drawings illustrate one or more examples of the present invention. The detailed description uses numerals and letters to refer to features in the drawings.

As used herein, the terms “first,” “second,” and “third,” etc., are used interchangeably to distinguish one component from another and are not intended to indicate the location or importance of individual components.
[0023] like Figures 1 to 2 As shown, according to an embodiment of the present invention, a slag pan residue crushing device is provided, such as... Figure 1As shown, the system includes an overhead crane, a lifting device 2, and a hydraulic breaker 3. The lifting device 2 is connected to the overhead crane via a chain 1, and the hydraulic breaker 3 is suspended on the lifting device 2. The overhead crane can lift the hydraulic breaker 3 via the lifting device 2. After the overhead crane lifts the hydraulic breaker 3 to a predetermined height, the hydraulic breaker 3 can automatically unlock from the lifting device 2 and fall at high speed into the slag pan 5. The high-speed falling hydraulic breaker 3 precisely strikes the remaining slag in the slag pan 5, thereby crushing the remaining slag in the slag pan 5.
[0024] Furthermore, such as Figure 2 As shown, the lifting device 2 includes a lifting handle 7 and a hook 8, which are integrally formed. One end of the lifting handle 7 is connected to one end of the hook 8, and the other end of the hook 8 extends to one side of the lifting handle 7. A through hole 9 is provided in the middle of the lifting handle 7, through which the lower end of the chain 1 is connected to the lifting device 2. The axis of the hook 8 is arc-shaped, with an arc angle of 45° and an arc length of 15cm. This design allows the hydraulic breaker 3 to disengage from the opening of the hook 8 after the lifting device 2 has rotated a certain angle.
[0025] Furthermore, it also includes a wire rope 11, with a positioning hole 10 at the other end of the lifting handle 7, and a lifting lug 6 on the slag pan 5; one end of the wire rope 11 is connected to the lifting lug 6, and the other end of the wire rope 11 is connected to the lifting handle 7 through the positioning hole 10. Since the weight of the slag pan 5 is significantly greater than the pulling force of the overhead crane lifting the breaker hammer 3, after the overhead crane lifts the breaker hammer 3 to the predetermined height, the wire rope 11 can pull the lifting handle 7 to rotate. After the lifting handle 7 rotates a certain angle, the breaker hammer 3 disengages from the opening of the hook 8, realizing the automatic unlocking of the breaker hammer 3 and the lifting device 2. This crushing device is based on the principle of mechanical balance and adopts a "gravity difference unlocking" mechanism (the weight of the slag pan 5 is greater than the weight of the breaker hammer 3), converting the weight of the slag pan 5 into a power source for unlocking the breaker hammer 3, without the need for additional energy drive, thus improving crushing efficiency and reducing labor intensity.
[0026] Furthermore, the breaker hammer 3 has a truncated pyramidal structure, and a lifting ring 4 is provided on the small end of the breaker hammer 3. The mass of the breaker hammer 3 is 50kg to 100kg. The hook 8 of the lifting device 2 engages with the lifting ring 4 of the breaker hammer 3. After the lifting device 2 lifts the breaker hammer 3 to the predetermined height, the wire rope 11 is gradually straightened. Under the tension of the wire rope 11, the lifting device 2 rotates around the connection between the chain 1 and the through hole 9. After the lifting device 2 rotates a certain angle, the breaker hammer 3 is released from the opening of the hook 8 and falls at high speed into the slag pan 5 under its own gravity. This crushing device achieves automatic operation through the automatic unlocking of the breaker hammer 3 and the hook 8. When the crane lifts the breaker hammer 3 to the preset height, the lifting device 2 triggers automatic unlocking, and the breaker hammer 3 falls freely under the action of gravity, accurately striking the remaining slag in the slag pan 5, efficiently completing the crushing operation, reducing manual intervention, effectively avoiding the safety risks of high-altitude operation and heavy object collision in traditional manual operation, ensuring the continuity and safety of the operation process, and at the same time, significantly reducing the labor intensity of operators, improving the comfort and efficiency of operation, and providing a solid guarantee for safe production.
[0027] The crushing device uses an overhead crane to lift the breaker hammer 3 to precisely impact the remaining slag in the slag pan 5. A single impact can generate a high-efficiency crushing force, and the remaining slag in the slag pan 5 can be crushed in just 2-3 operations. This significantly improves the processing efficiency compared to a blasting machine, while effectively reducing equipment operating time and fuel consumption, and significantly reducing operating noise. This achieves a triple optimization of steel slag processing efficiency, cost, and environmental benefits.
[0028] Furthermore, the overhead crane can lift the breaker 3 to a height of 10m, ensuring that the breaker 3 has sufficient impact force to achieve the purpose of crushing the remaining slag in the slag pan 5.
[0029] like Figure 3 As shown, the method for crushing residual slag in the slag pan using this crushing device includes the following steps:
[0030] Step 1: Position the overhead crane. When solidified mixture (residual slag) appears in slag pan 5, the operator controls the overhead crane to precisely position it directly above slag pan 5, providing a spatial basis for subsequent operations.
[0031] Step 2: Install the lifting device 2, fasten one end of the lifting device 2 to the lifting ring 4 of the breaker 3, and securely connect the other end of the lifting device 2 to the chain 1 of the overhead crane;
[0032] Step 3: Install wire rope 11, reliably connect one end of wire rope 11 to the lifting lug 6 of slag pan 5, and insert the other end of wire rope 11 into the positioning hole 10 of lifting device 2 and lock it, forming a double connection system of overhead crane, lifting device 2, breaker hammer 3 and slag pan 5, wire rope 11 and lifting device 2.
[0033] Step 4: Lift the hydraulic breaker 3. The overhead crane starts the lifting mechanism and smoothly lifts the hydraulic breaker 3 using the lifting device 2.
[0034] Step 5, single-stage slag crushing: When the crane lifts the breaker hammer 3 to the predetermined height, the wire rope 11 is gradually straightened. Since the weight of the slag pan 5 is significantly greater than the pulling force of the crane lifting the breaker hammer 3, under the tension of the wire rope 11, the lifting device 2 is automatically unlocked, and the breaker hammer 3 falls at high speed and accurately impacts the solidified mixture in the slag pan 5, thus achieving single-stage crushing of the slag in the slag pan 5.
[0035] Step 6: Crush the remaining slag. After each crushing operation, repeat steps 4 and 5 until the remaining slag in the slag pan 5 is completely crushed.
[0036] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:
[0037] 1. The crushing device has a simple structure and is easy and efficient to operate. Operators only need to accurately fasten the lifting tool 2 onto the lifting ring 4 of the breaker hammer 3 to quickly complete the lifting preparation, which greatly shortens the operation preparation time and significantly improves the convenience of operation.
[0038] 2. When the crane lifts the breaker hammer 3 to the preset height, the lifting device 2 is automatically unlocked, and the breaker hammer 3 falls freely under the action of gravity, accurately hitting the remaining slag in the slag pan 5, efficiently completing the crushing operation without the need for secondary manual intervention, ensuring the continuity and safety of the operation process.
[0039] 3. The crushing device features an automatic unlocking design between the breaker hammer 3 and the lifting device 2, which minimizes manual intervention and effectively avoids safety risks such as high-altitude operations and heavy object collisions in traditional manual operations. At the same time, it significantly reduces the labor intensity of operators, improves work comfort and efficiency, and provides a solid guarantee for safe production.
[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
