[0002] In the existing technology, the slag sample extraction device faces a significant problem during the converter steelmaking operation: due to the high hardness of some steel slags, if the scraper in the extraction device exerts too much force during sampling, the scraper may be damaged. This phenomenon has a negative impact on the use effect of the extraction device.

[0003] The damage of the scraper not only reduces the service life of the extraction device, but also may lead to inaccurate sampling, affecting the control of the steelmaking process and the product quality. During the converter steelmaking process, accurate slag sample analysis is crucial for optimizing the smelting process and ensuring product quality. Therefore, the damage of the scraper not only increases the maintenance cost, but also may have an adverse impact on the normal operation of the steel plant. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a slag sample sampling device for the steelmaking process in view of the deficiencies of the existing technology. When the strength of the steel slag exceeds the friction force between the connecting mechanism and the follower mechanism, the slider and the limiting rod are separated from each other, so that the scraper can rotate idly with the connecting mechanism, realizing the protection of the scraper and avoiding the damage of the scraper.

Detailed implementation manners

[0031] The preferred embodiments of the present utility model will be described in more detail below. Although the preferred embodiments of the present utility model are described below, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.

[0032] The present utility model provides a slag sample sampling device for the steelmaking process, including a connection mechanism, a follow-up mechanism, and a collection mechanism. The connection mechanism connects two limit rods through a bidirectional rod. The limit rod not only realizes the transmission of the acting force, but also through the cooperation of the limit rod and the follow-up mechanism, enables the scraper to switch between the connected and disconnected states. When the strength of the steel slag is relatively large, in order to ensure that the scraper will not be damaged, the connection between the follow-up mechanism and the limit rod is disconnected, so that the scraper can rotate idly and will not make the scraper come into hard contact with the steel slag; one limit rod is connected to an external transmission structure, and the rotational force is transmitted to the collection mechanism through one limit rod, the bidirectional rod, and the other limit rod in sequence, driving the collection mechanism to rotate, so that the scraper can cut the steel slag, and the sampled slag is collected through the collection shell.

[0033] A fixed sleeve, a shrinkage block, a positioning sleeve and a rotating sleeve are also provided in the connecting mechanism. Except that one end of the limit rod which is away from each other is located outside the fixed sleeve, the other parts of the limit rod and the bidirectional rod are arranged in the fixed sleeve. Two groups of shrinkage blocks are respectively provided at both ends of the fixed sleeve. Each group of shrinkage blocks has a plurality of circumferentially arranged blocks to form a conical hole in the fixed sleeve. The hole is coaxially arranged with the fixed sleeve. The closer the hole is to the end of the fixed sleeve, the smaller the aperture is. Two rotating sleeves are provided in the middle of the fixed sleeve. The two ends of the first spring on the outer periphery of the bidirectional rod are respectively against the rotating sleeve. The rotating sleeve is slidably fixed in the fixed sleeve by the positioning sleeve, so that when the limit rod rotates with a rotating force, the first spring and the rotating sleeve can rotate synchronously, and the first spring and the rotating sleeve will not deflect during the rotation process. In addition, in the natural state of the first spring, the spring pushes the rotating sleeve to move toward the two ends of the fixed sleeve, and the rotating sleeve drives the slider to the end with a smaller aperture in the shrinkage block through the second spring. Since the pressure plate is tightly held around the limit rod, the clamping force will be further increased to form a self-locking situation, and the scraper can cut the slag with a greater force.

[0034] A threaded sleeve is also provided in the follow-up mechanism, and the threaded sleeve is threadedly connected to the outside of the fixed sleeve. When it is necessary to disconnect the pressure plate and the limit rod, the threaded sleeves at both ends of the fixed sleeve need to be rotated in the direction of approaching each other, so that the threaded sleeve can push the push plate to move toward the middle section of the fixed sleeve, so that the slider moves toward the end with a larger aperture of the shrinkage block, and the extrusion force applied by the pressure plate to the limit rod is reduced. Finally, the pressure plate and the limit rod are separated from each other. When the scraper encounters harder slag, the scraper will protect itself, and the scraper will not come into head-on contact with the slag, thereby avoiding damage to the scraper.

[0035] A hexagonal sleeve is arranged on the threaded sleeve, so that the threaded sleeve can be rotated by a wrench, and adjustment is more convenient.

[0036] An intermediate spring is arranged between multiple collecting shells. When the collecting shell is driven to rotate by an external driving device, the scraper will fit on the slag, and then flow into the collecting shell through the separator. The design of multiple intermediate springs ensures that the angle can be changed with the converter, thereby improving the diversity of extraction and further improving the use effect.

[0037] Example

[0038] like Figures 1 to 5 As shown, the utility model provides a slag sampling device for a steelmaking process, comprising:

[0039] The connection mechanism includes two limit rods 5 and a plurality of contraction blocks 3. The contraction blocks 3 are surrounded by the outer periphery of the limit rod 5. One end of the limit rod 5 located at the top is used for connecting with an external transmission mechanism. The inner side of the contraction block 3 gradually decreases the distance between the limit rod 5 and the inner end of the limit rod 5 along the outer end of the limit rod 5 toward the inner end of the limit rod.

[0040] A follower mechanism is arranged on the outer periphery of the limit rod 5. The follower mechanism includes a slider 4 and a push plate 13 that move along the axial direction of the limit rod. The outer end of the push plate 13 extends to the outside of the connecting mechanism. The inner end of the push plate 13 is connected to the outer side of the slider 4. The inner side of the slider 4 is matched with the outer surface of the limit rod 5.

[0041] A collection mechanism is connected to the lower end of the limit rod 5 located below. The collection mechanism includes a collection shell 1 and a scraper 17. The scraper 17 is arranged on the outer periphery of the collection shell 1.

[0042] In this embodiment, the connecting mechanism further includes a fixing sleeve 2. The fixing sleeve 2 is sleeved on the outer periphery of the two limit rods 5. A lateral groove 14 is formed on the fixing sleeve 2. The push plate 13 is slidably arranged in the lateral groove 14. The outer side of the contraction block 3 is connected to the inner wall of the fixing sleeve 2.

[0043] In this embodiment, the limit rods 5 are connected by a bidirectional rod 8. A first spring 9 is sleeved on the outer periphery of the bidirectional rod 8. Both ends of the first spring 9 abut against the slider 4.

[0044] In this embodiment, a positioning sleeve 11 is arranged inside the fixing sleeve 2. A rotating sleeve 12 is rotatably arranged inside the positioning sleeve 11. One relatively close end of the rotating sleeve 12 is connected to the end of the first spring 9. The relatively far end of the rotating sleeve 12 is connected to the slider 4 through a second spring.

[0045] In this embodiment, an insertion hole 10 is arranged at one relatively close end of the limit rod 5. The bidirectional rod 8 is inserted into the insertion hole 10.

[0046] In this embodiment, the follower mechanism includes a threaded sleeve 15 screwed on the outside of the fixing sleeve 2. The end of the threaded sleeve 15 abuts against one end of the push plate 13. A hexagonal sleeve 16 is arranged on the threaded sleeve 15.

[0047] In this embodiment, the follower mechanism further includes a pressure plate 7. One side of the pressure plate 7 is connected to the other side of the slider 4 through a compression spring 6. The other side of the pressure plate 7 is in sliding fit with the outer surface of the limit rod 5.

[0048] In this embodiment, a plurality of collection shells 1 are provided. Adjacent collection shells 1 are connected by an intermediate spring 18.

[0049] In this embodiment, a partition piece 19 is arranged inside the collection shell 1. The partition piece 19 is bent to form a slag sample collection cavity. Both ends of the partition piece 19 are respectively connected to the scraper 17.

[0050] In this embodiment, a plurality of guide pieces 20 are arranged in the slag sample collection cavity.

[0051] In summary, during the use of this slag sample sampling device: when steel slag collection is required, first, an external device drives the rotation of the limit rod 5, and then drives the scraper 17 to fit on the steel slag, thus completing the collection process. When the force of the steel slag exceeds the elastic force of the compression spring 6, the connection between the pressure plate 7 and the limit rod 5 will be released, so as to avoid damaging the scraper 17. Due to the positioning between the two limit rods 5 being ensured by the action of the bidirectional rod 8 and being pushed on the two limit rods 5 by the spring 9, the two limit rods 5 tend to move outwards. Since the pressure plate 7 presses on the limit rod 5, it will move accordingly. Since the outward movement causes the slider 4 to contract along the contraction block 3, the clamping force will be further increased, thus forming a self-locking situation, and the clamping process can be completed. In this way, the steel slag can be cut by the scraper 17; when the connection between the two needs to be released, rotating the threaded sleeve 15 can drive the movement of multiple push plates 13, causing the multiple sliders 4 to slide and expand relative to each other, thus releasing the connection with the limit rod 5, and then completing the release process.

[0052] The various embodiments of the present invention have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
