Description

Technical Field

[0001] This utility model belongs to the field of steel slag transfer and unloading technology, specifically relating to a steel slag hot-baking unloading device with a splash-proof structure. Background Technology

[0002] In the steel metallurgical production process, the treatment of steel slag is a crucial step. Currently, the hot quenching process is widely used to cool and pulverize high-temperature molten steel slag. In this process, high-temperature steel slag produced by converters, electric furnaces, etc., is typically hoisted and transported to a dedicated hot quenching tank for water spraying and quenching.

[0003] Under current technology, the commonly used operating method is to use lifting equipment to hoist a hopper carrying steel slag directly above the hot quenching tank, and then use simple mechanical traction to tilt the hopper, causing a large amount of steel slag to be dumped into the tank in a short period of time. This one-time dumping method has significant drawbacks: the sudden fall of high-temperature steel slag creates a huge impact on the tank, which can easily trigger violent molten slag splashing and explosive spraying. This phenomenon not only seriously threatens the personal safety of on-site operators, but may also damage the walls of the hot quenching tank, water spray devices, and other surrounding equipment, while causing a large amount of smoke and dust to escape instantly, polluting the working environment. In addition, concentrated dumping affects the overall effect and efficiency of the hot quenching treatment.

[0004] Therefore, this utility model proposes a steel slag hot-baking feeding device with a splash-proof structure, which can realize slow feeding, suppress the impact force when steel slag enters the pool, eliminate splashing, and improve the safety, environmental protection and automation level of the steel slag treatment process. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot slag feeding device with a splash-proof structure, comprising a hopper and a hanger. The top two sides of the hopper are integrally connected with first lifting lugs. The top of the hopper has a feed inlet, and the bottom of the hopper has a discharge outlet. A baffle structure is installed at the discharge outlet of the hopper. The baffle structure includes a baffle body. The top of the baffle body and the bottom of the hopper are slidably connected. The bottom end face of the baffle body is uniformly welded with first reinforcing ribs. One end of the first reinforcing ribs is hinged to a connecting beam. A hook assembly is fixed at the center of the connecting beam.

[0006] As a preferred embodiment of this utility model, the bottom of the hopper has an inverted conical structure, and the outer wall of the hopper is uniformly welded with a second reinforcing rib.

[0007] As a preferred technical solution of this utility model, the cross-sections of the baffle body and the bottom edge of the discharge port are both arc-shaped structures, and the bottom edge of the discharge port is set to fit the inner surface of the baffle body.

[0008] As a preferred embodiment of this utility model, the hanger includes a crossbeam, a second lifting lug integrally connected to the center of the top of the crossbeam, and hooks hinged to both sides of the bottom of the crossbeam, with the hook body hooked to the first lifting lug.

[0009] As a preferred embodiment of this utility model, the hook assembly includes a side plate, which is symmetrically fixed to both sides of the connecting beam. A connector is fixed to the bottom of the side plate, and a hook rod is fixed to the bottom of the connector.

[0010] As a preferred embodiment of this utility model, a supporting rib is fixed between adjacent first reinforcing ribs and adjacent second reinforcing ribs.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This device uses a sliding slow-opening design of the baffle body to allow steel slag to enter the hot quenching tank at a low speed and in a uniform manner, which completely eliminates the risk of molten slag splashing and explosive spraying caused by the sudden drop of high-temperature steel slag. This not only ensures the personal safety of on-site operators, but also avoids damage to the walls of the hot quenching tank, water spraying devices and other surrounding equipment due to impact, thus solving the safety pain points of traditional processes.

[0013] (2) In the traditional centralized one-time dumping mode, the violent impact of steel slag will cause a large amount of smoke and dust to spread instantly, polluting the working environment. This device allows the steel slag to enter the pool smoothly by slow feeding, which greatly reduces the amount of smoke and dust generated and the diffusion speed. Combined with the sealing facilities of the hot blanching pool, it can effectively control the spread of smoke and dust, which meets the environmental protection production standards of the steel industry and reduces the impact on the surrounding environment and personnel health.

[0014] (3) The second reinforcing rib on the outer wall of the hopper, the first reinforcing rib at the bottom of the baffle body and the supporting rib between them form a multi-dimensional structural reinforcement system, which can effectively resist the gravity load, material impact and thermal expansion and contraction stress of high temperature steel slag, avoid deformation or damage of the hopper and baffle due to long-term use, extend the overall service life of the device, and reduce equipment maintenance costs and replacement frequency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figure 1-3 The present invention provides the following technical solution: a hot slag feeding device with a splash-proof structure, comprising a hopper 1 and a hanger. The top two sides of the hopper 1 are integrally connected with first lifting lugs 2. The top of the hopper 1 is provided with a feed inlet 3 and the bottom of the hopper 1 is provided with a discharge outlet 4. A baffle structure is installed at the discharge outlet 4 of the hopper 1. The baffle structure includes a baffle body 5. The top of the baffle body 5 and the bottom of the hopper 1 are slidably connected. The bottom end face of the baffle body 5 is uniformly welded with a first reinforcing rib 6. One end of the first reinforcing rib 6 is hinged to a connecting beam 7. A hook assembly is fixed at the center of the connecting beam 7.

[0023] In order to utilize gravity to guide the steel slag to naturally collect at the discharge port 4, and at the same time enhance the structural strength of the outer wall of the hopper 1 to resist the gravity load and thermal stress of the high-temperature steel slag, in this embodiment, as a preferred technical solution of the present invention, the bottom of the hopper 1 has an inverted conical structure, and the outer wall of the hopper 1 is uniformly welded with a second reinforcing rib 8.

[0024] In order to achieve a reliable seal of the discharge port 4 through the tight fit of the arc-shaped surfaces and prevent steel slag leakage or spillage during loading and hoisting, in this embodiment, as a preferred technical solution of the present invention, the cross-section of the bottom edge of both the baffle body 5 and the discharge port 4 is an arc-shaped structure, and the bottom edge of the discharge port 4 is fitted to the inner surface of the baffle body 5.

[0025] In order to construct a stable hoisting and load-bearing system, achieve precise and reliable connection between external hoisting equipment and hopper 1, ensure the balance and stability of hopper 1 during hoisting, and avoid steel slag shaking and spillage due to hoisting offset, in this embodiment, as a preferred technical solution of this utility model, the hoist includes a crossbeam 9, a second lifting lug 10 integrally connected at the top center of the crossbeam 9, and hooks 11 hinged on both sides of the bottom of the crossbeam 9, with the hook body of the hook 11 hooked at the first lifting lug 2.

[0026] In order to provide a standardized and stable connection carrier for the external automated traction mechanism, and to ensure that the traction force can be evenly transmitted to the connecting beam 7 and to achieve precise control of the feeding rate, in this embodiment, as a preferred technical solution of the present invention, the hook assembly includes a side plate 12, which is symmetrically fixed on both sides of the connecting beam 7. A connector 13 is fixed at the bottom of the side plate 12, and a hook rod 14 is fixed at the bottom of the connector 13.

[0027] In order to further disperse the gravity load and impact of the high-temperature steel slag, prevent the hopper 1 and the baffle body 5 from deforming due to local stress concentration, and improve the overall structural stability of the device, in this embodiment, as a preferred technical solution of the present invention, a supporting rib 15 is fixed between the adjacent first reinforcing rib 6 and the adjacent second reinforcing rib 8.

[0028] In summary, by utilizing the above-mentioned technical solution of this utility model, the slow and safe introduction of high-temperature steel slag into the pool is achieved. The specific workflow is as follows:

[0029] 1. Loading and Sealing Preparation Stage: High-temperature steel slag is loaded into the hopper 1 through the feed inlet 3 at the top of the device. The inverted cone-shaped structure at the bottom of the hopper 1 can use gravity to guide the steel slag to naturally collect to the discharge port 4. At this time, the baffle body 5 and the bottom edge of the discharge port 4 are tightly fitted in an arc shape. Through the sealing adaptability of the arc surface, the discharge port 4 is completely sealed by the weight of the baffle body 5, effectively preventing steel slag leakage or spillage during loading and hoisting.

[0030] II. Lifting Connection and Positioning Stage: The hanger serves as a load-bearing connection structure, with its hooks 11 on both sides precisely hooking into the first lifting lug 2 on the top of the hopper 1, forming a stable lifting arrangement; external lifting equipment, such as a bridge crane, hooks into the second lifting lug 10 on the top of the hanger beam 9 to achieve overall lifting and fixing of the hopper 1 carrying steel slag; subsequently, the lifting equipment lifts the hopper 1 to directly above the hot quenching tank, adjusts the position of the hopper 1 so that the discharge port 4 is vertically aligned with the feeding area of ​​the hot quenching tank, and completes the positioning before discharge.

[0031] III. Slow Discharge Control Stage: Through the connection between the external automated traction mechanism, such as the winch, and the hook rod 14 of the hook assembly, the traction mechanism slowly applies tension through the hook rod 14 and the connector 13 to the connecting beam 7. Since the connecting beam 7 is hinged to the first reinforcing rib 6 at the bottom of the baffle body 5, the tension is evenly transmitted to the baffle body 5 through the first reinforcing rib 6, driving the baffle body 5 to move smoothly along the sliding track at the bottom of the hopper 1, so that the discharge port 4 gradually opens from the closed state.

[0032] Under the influence of gravity, the steel slag flows evenly along the inverted conical inner wall of the hopper 1 to the open discharge port 4, and falls into the hot slag pool at a low speed and continuously. By adjusting the pulling speed of the traction mechanism, the opening of the baffle body 5 can be precisely controlled, thereby realizing the dynamic adjustment of the steel slag discharge rate and avoiding the concentrated falling of steel slag in a short period of time.

[0033] IV. Material Discharge Completion and Reset Stage: After all the steel slag in hopper 1 has been discharged, the baffle body 5 resets under its own weight, slides along the bottom of hopper 1 to the initial position, and re-fits with the arc edge of the discharge port 4 to close the discharge port 4; then the lifting equipment lifts the empty hopper 1 to the loading area and enters the next round of operation.

[0034] During this process, the second reinforcing rib 8 on the outer wall of the hopper 1 and the supporting rib 15 between the adjacent first reinforcing rib 6 and the second reinforcing rib 8 can effectively disperse the gravity load and material impact of the high-temperature steel slag, prevent the hopper 1 and the baffle body 5 from deforming, and ensure the structural stability of the device.
