Description

Technical Field

[0001] This utility model relates to the technical field of electro-hydraulic slag cleaning devices, and in particular to a fully automatic mechanical reciprocating electro-hydraulic slag cleaning device. Background Technology

[0002] During the refining furnace smelting process, slag is generated on the furnace cover. After being cooled by the water cooling of the furnace cover, the slag falls off naturally and gradually accumulates in the slag channel. After accumulation, it forms refined steel slag blocks in the pit. The accumulation affects the operation and entry and exit of the ladle car and poses a safety hazard to the equipment and process equipment at the bottom of the ladle. Personnel need to clean the refined steel slag in the slag channel from time to time.

[0003] Current cleaning methods primarily rely on manual labor. During manual labor, there is still a risk of slag falling or collapsing inside the furnace cover. Given the extremely high risks associated with manual slag removal during the refining and smelting process, a safer and more efficient cleaning method is urgently needed. Utility Model Content

[0020] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of implementation of this utility model. Therefore, they have no substantial technical significance.

[0021] Please refer to Figure 1 , Figure 2 This utility model discloses a fully automatic mechanical reciprocating electro-hydraulic slag cleaning device, which includes a drive assembly and a flap assembly.

[0022] It should be noted that the directions up and down and left and right mentioned below refer to... Figure 1 The top, bottom, left, and right directions in the middle.

[0023] The drive assembly includes a rotating component and a telescopic component 4. The rotating component is hinged to the bottom of the ladle car, with the hinge axis perpendicular to the telescopic direction of the telescopic component 4. The flap assembly includes a flap 6 and multiple slag-cleaning components 7. The flap 6 is mounted on the rotating component. The slag-cleaning components 7 are mounted on the flap 6. The telescopic component 7 has a lowered state and a retracted state. When the slag-cleaning component 7 is in the lowered state, it is close to the bottom of the slag channel and can move with the ladle car 1 within the slag channel to clean the steelmaking slag blocks in the slag channel. When the slag-cleaning component 7 is in the retracted state, it is away from the bottom of the slag channel. The telescopic component 4 drives the rotating component to rotate, thereby switching the slag-cleaning component 7 between the retracted and lowered states.

[0024] Specifically, the telescopic component 4 can be a device with telescopic function, such as a cylinder, an electric actuator, or a hydraulic cylinder. In this embodiment, the telescopic component 4 is an electric actuator. The electric actuator includes a main body 41 and a push rod 42. The main body 41 is installed on the lower side of the ladle car 1. The push rod 42 is slidably disposed inside the main body 41 and can extend and retract in the horizontal direction, with the extension and retraction direction parallel to the movement direction of the ladle car 1.

[0025] The rotating component is generally L-shaped, including a first rotating plate 2 and a second rotating plate 3. The width direction of both the first rotating plate 2 and the second rotating plate 3 is parallel to the width direction of the slag channel. The lower side of the first rotating plate 2 is fixedly connected to the left side of the second rotating plate 3 and then hinged to the bottom of the ladle car 1. Since the push rod extends and retracts in the horizontal direction, the hinge axis of the rotating component is horizontal and perpendicular to the extension and retraction direction of the extension and retraction component 4. Therefore, the rotating component can convert the extension and retraction motion of the push rod into the rotation of the slag cleaning component 7 around the hinge axis of the rotating component, thereby realizing the switching between the retracted state and the lowered state of the slag cleaning component 7.

[0026] The rotating component can be hinged to the ladle car 1 using suitable components such as a pin or hinge 5. In this embodiment, the rotating component is hinged to the bottom of the ladle car 1 via hinge 5.

[0027] When the widths of the first rotating plate 2 and the second rotating plate 3 are large, the rotation of the rotating component supported by a single hinge 5 becomes unstable. Therefore, in a preferred embodiment of this invention, there are multiple hinges 5, which are evenly spaced along the width direction of the slag channel.

[0028] Please continue to refer to Figure 1 , Figure 2 The flap 6 is flat and is fixedly connected to the right side of the second rotating plate 3. Alternatively, the lower part or all of the flap 6 is fixedly connected to the upper side of the second rotating plate 3. In practical applications, when the slag-cleaning component 7 is cleaning slag, both the flap 6 and the slag-cleaning component 7 on it are subjected to a large reaction force. In order to ensure the firmness of the flap 6 installation, in a preferred embodiment of this utility model, the lower part of the flap 6 is fixedly connected to the upper side of the second rotating plate 3.

[0029] The slag-cleaning component 7 is located below the flap 6 and away from the rotating component. The slag-cleaning component 7 cleans the steelmaking slag blocks in the slag channel by pushing, and can be of various shapes such as long rods, flat plates, or arcs. Because the slag-cleaning component 7 is long rods or flat plates, it is easy for it to get stuck in the gaps between the steelmaking slag blocks and become difficult to move, and there is even a risk of breakage. Therefore, in a preferred embodiment of this invention, the longitudinal section of the slag-cleaning component 7 is arc-shaped.

[0030] Specifically, the upper edge of the slag cleaning component 7 is fixedly connected to the bottom right side of the flap 6, the middle part rises horizontally and away from the flap 6, and the lower edge bends horizontally and towards the flap 6, thus making the longitudinal section of the slag cleaning component 7 arc-shaped. This smoothly transitioned shape of the slag cleaning component 7 makes it less susceptible to obstruction by steelmaking slag blocks, which helps improve the slag cleaning efficiency of the slag cleaning component 7.

[0031] To further improve slag removal efficiency, the fully automatic mechanical reciprocating electro-hydraulic slag removal device of this utility model also includes a controller. The controller is communicatively connected to the telescopic component 4 and can control the movement of the telescopic component 4. The controller is also communicatively connected to the control component that controls the movement of the ladle car 1, realizing automatic control of the telescopic component 4 when the ladle car 1 moves. By programming the control component that controls the movement of the ladle car 1, it is possible to realize that when slag removal is needed, the controller controls the telescopic component 4 to extend, causing the rotating component to rotate and switching the slag removal component 7 to the lowered state; or when slag removal is not needed, the controller controls the telescopic component 4 to retract, causing the rotating component to rotate in the opposite direction and switching the slag removal component 7 to the retracted state.

[0032] The operating principle of this fully automatic mechanical reciprocating electro-hydraulic slag cleaning device is as follows: When slag cleaning is required, the control component controlling the movement of the ladle car 1 controls the slag cleaning component 7 to switch to the lowered state via the controller, and simultaneously controls the movement of the ladle car 1, causing the ladle car 1 to move the slag cleaning component 7, which is in the lowered state, within the slag channel, thereby cleaning the steelmaking slag blocks within the slag channel. When slag cleaning is not required, the control component controlling the movement of the ladle car 1 controls the slag cleaning component 7 to switch to the retracted state via the controller, and simultaneously controls the movement of the ladle car 1. The slag cleaning component 7, in the retracted state, will not obstruct the movement of the ladle car 1.

[0033] This utility model's fully automatic mechanical reciprocating electro-hydraulic slag cleaning device, by installing a slag cleaning component 7 on the underside of the ladle car 1, which can switch between a lowered state and a retracted state, replaces manual cleaning of steelmaking slag blocks in the slag channel, avoiding safety risks for workers during slag cleaning operations. Furthermore, the slag cleaning operation can be fully automatically controlled by a control component that controls the movement of the ladle car 1 or by a host computer connected to this component, requiring no manual intervention and improving the efficiency of the slag cleaning operation.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
