Description

Technical Field

[0001] This application relates to the technical field of crucible cleaning, and in particular to a crucible quick unloading structure. Background Technology

[0002] In the copper rod production process, the crucible, as a core piece of equipment for smelting and casting, directly affects the composition and quality of subsequent products due to residual materials inside. Currently, the copper rod manufacturing industry generally adopts an intermittent production method, requiring thorough cleaning of residual materials from the crucible after each batch to avoid cross-contamination. In recent years, the penetration rate of automated equipment in the metallurgical field has gradually increased, but specialized crucible cleaning technologies for the production of multiple alloys still exist.

[0003] Currently, the industry mainly uses three cleaning methods: First, manual tapping, where operators use steel bars to tap the inner wall of the crucible to remove the residue. This method is labor-intensive and poses safety hazards. Second, high-pressure air blowing, which removes the residue by spraying compressed air. However, this method is energy-intensive and easily causes dust pollution. Third, tilting and dumping, which involves turning the entire crucible over to dump the residue. This method requires a large tilting mechanism and is difficult to completely remove the adhering material.

[0004] Regarding the aforementioned technologies, the inventors believe that manual tapping is time-consuming and has unstable cleaning results; high-pressure air blowing has high equipment investment costs and high noise levels; and tilting and pouring methods are inconvenient to operate and will accelerate the wear of the crucible lining, reducing its service life by 30%. Existing technologies cannot achieve rapid, thorough, and environmentally friendly removal of crucible residues. Utility Model Content

[0005] In order to quickly clean up the waste generated during crucible production, this application provides a crucible quick unloading structure.

[0006] The crucible rapid unloading structure provided in this application adopts the following technical solution: A crucible rapid unloading structure includes a crucible body, an outer casing, and a cleaning assembly. The outer casing has a connection port at its top. The crucible body is housed within the outer casing and within the connection port. A melting tank is located at the top of the crucible body. The cleaning assembly includes a slag discharge pipe, an electric valve, and a collection pipe. The slag discharge pipe is vertically connected to the bottom surface of the crucible body and communicates with the melting tank. The electric valve is mounted on the slag discharge pipe. The collection pipe is a square tube located on the inner bottom wall of the outer casing and below the crucible body. A slag collection port is opened on the top surface of the collection pipe, and the bottom end of the slag discharge pipe extends into the collection pipe through the slag collection port.

[0007] By adopting the above technical solution, after the crucible body completes melting, the electric valve opens, and the waste slag in the melting tank is discharged into the collection pipe through the slag discharge pipe, achieving rapid cleaning of the waste slag. Through the cooperation of the crucible body, outer box, and cleaning components, rapid collection of crucible waste slag is achieved, effectively cleaning up waste generated during crucible production.

[0008] Optionally, the cleaning assembly further includes a cleaning cylinder and a cleaning push plate. The cleaning push plate is vertically disposed in the collection pipe, and the cleaning cylinder is disposed on the outer casing. The output shaft of the cleaning cylinder is parallel to the length direction of the collection pipe, and the output shaft of the cleaning cylinder extends into the collection pipe and is connected to the cleaning push plate in a driving connection.

[0009] By adopting the above technical solution, after a period of collection, the collection pipe is filled with waste residue. At this time, the cleaning cylinder is activated, which drives the cleaning push plate to move in the collection pipe and push the waste residue out of the collection pipe.

[0010] Optionally, a connecting lug is provided on the vertical side wall of the crucible body, a guide rod is vertically connected in the outer box, the guide rod passes through the connecting lug and slides with it, and a driving component is provided in the outer box for driving it to move in the vertical direction.

[0011] By adopting the above technical solution, before cleaning the waste residue in the collection tube, the crucible body moves upward under the drive of the driving component and the guidance of the guide rod, and the slag discharge pipe moves out of the collection tube, thus avoiding the collision between the cleaning push plate and the slag discharge pipe during the slag discharge process.

[0012] Optionally, a sealing ring is provided on the edge of the cleaning push plate, and the sealing ring is fitted to the inner wall of the collection tube.

[0013] By adopting the above technical solution, the sealing ring reduces the possibility of waste residue adhering to the inner wall of the collection pipe.

[0014] Optionally, a groove is provided on the top surface of the collecting pipe along its length, a connecting cover plate is provided on the top surface of the collecting pipe, a slider is provided on the bottom surface of the connecting cover plate, the connecting cover plate is slidably connected to the groove through the slider, and a driving component is provided on the connecting pipe for driving the connecting cover plate to move.

[0015] By adopting the above technical solution, when it is necessary to discharge the waste residue in the collection pipe, the connecting cover plate will block the slag collection port under the drive of the drive component, thus preventing the waste residue from leaking out of the slag collection port during the slag discharge process and affecting the internal environment of the outer box.

[0016] Optionally, a support block is connected to the inner bottom wall of the outer box. The support block includes a vertical part and a horizontal part connected to its top. When the crucible body moves to abut against the top of the horizontal part, the top of the crucible body is flush with the top of the outer box.

[0017] By adopting the above technical solution, the support block limits and supports the crucible body, avoiding the collision between the bottom of the slag discharge pipe and the inner wall of the collection pipe caused by the crucible body falling too low.

[0018] Optionally, an observation window is provided on one of the vertical side walls of the outer casing.

[0019] By adopting the above technical solution, the setting of the observation window makes it easier for operators to observe the slag collection in the outer box.

[0020] Optionally, a vibration motor is installed on the slag discharge pipe.

[0021] By adopting the above technical solution, the vibration motor vibrates during the slag removal process, which helps to dislodge the waste slag from the smelting tank and improves the efficiency of the slag removal process.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the crucible body, outer box and cleaning components, the crucible waste residue is collected quickly, and the waste generated during crucible production is cleaned up quickly. 2. The design of the connecting cover plate prevents waste residue from leaking out of the slag collection port during the slag discharge process and affecting the internal environment of the outer casing; 3. The observation window facilitates operators' observation of the slag collection in the outer box. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be further described in detail below. Embodiments of this application provide a crucible rapid unloading structure, which has the effect of quickly cleaning up waste generated during crucible production.

[0029] Reference Figure 1-3 A rapid crucible unloading structure includes a crucible body 1, an outer casing 2, and a cleaning assembly 3. The crucible body 1 is housed within the outer casing 2. The top of the outer casing 2 has a connection port 21 for the crucible body 1 to extend out. One of the vertical inner walls of the outer casing 2 has an observation window 22 for observing the interior of the outer casing 2. Figure 4 The outer casing 2 is equipped with a heating resistance plate 4 for heating. Two melting tanks 101 are opened parallel to each other on the top surface of the crucible body 1, and the inner bottom wall of the melting tank 101 is provided with an inclined surface.

[0030] Reference Figure 2 and Figure 3 The cleaning component 3 includes a slag discharge pipe 31, an electric valve 32, a collection pipe 33, a cleaning push plate 34, a sealing ring 35, and a cleaning cylinder 36. Two slag discharge pipes 31 are vertically connected to the bottom surface of the crucible body 1. Each slag discharge pipe 31 corresponds to and is connected to one of the two melting tanks 101, with the slag discharge pipe 31 located at the lowest point of the melting tank 101. Each slag discharge pipe 31 is equipped with an electric valve 32 and a vibration motor 6. The collection pipe 33 is a square pipe with one open end and the other closed end. The collection pipe 33 is located on the inner bottom wall of the outer casing 2, below the crucible body 1, with its open end extending out of the outer casing 2. A slag collection port 331 is formed on the top surface of the collection pipe 33, and the bottom end of the slag discharge pipe 31 extends into the slag collection port 331.

[0031] Reference Figure 4Two horizontally arranged connecting lugs 7 are horizontally connected to the vertical side wall of the crucible body 1. A lifting motor 9 is installed in the outer casing 2. A lifting screw 8 is vertically driven to the output shaft of the lifting motor 9. The top end of the lifting screw 8 is rotatably connected to the inner top wall of the outer casing 2. The lifting screw 8 is threadedly connected to one of the connecting lugs 7. A guide rod 10 is connected vertically in the outer casing 2. The guide rod 10 passes through the other connecting lug 7 and is slidably connected to it. A cleaning push plate 34 is vertically arranged in the collection tube 33. A sealing ring 35 is arranged on the edge of the cleaning push plate 34 and fits against the inner peripheral wall of the collection tube 33. A cleaning cylinder 36 is arranged on the outer casing 2. The output shaft of the cleaning cylinder 36 is arranged along the length of the collection tube 33 and extends into the collection tube 33 to be drivenly connected to the cleaning push plate 34.

[0032] Reference Figure 4 A support block 11 is provided on the inner bottom wall of the outer box 2. The support block 11 includes a vertical part 111 and a horizontal part 112. One side of the horizontal part 112 is connected to the top edge of the vertical part 111, and the vertical part 111 is vertically connected to the inner bottom wall of the outer box 2. When the bottom end of the crucible body 1 is placed on the horizontal part 112, the slag discharge pipe 31 is inserted into the inner cavity of the collection pipe 33.

[0033] Reference Figure 2-4 Two chutes 332 are arranged parallel to each other along the length of the top surface of the collecting pipe 33, and the two chutes 332 are located on opposite sides of the slag collection port 331. A connecting cover plate 12 is provided on the top surface of the collecting pipe 33, and two sliders 13 are provided on the bottom surface of the connecting cover plate 12. The two sliders 13 correspond one-to-one with the two chutes 332 and are slidably connected. A connecting cylinder 5 is provided on the top surface of the collecting pipe 33. The output shaft of the connecting cylinder 5 is arranged parallel to the collecting pipe 33 and is drivenly connected to the connecting cover plate 12.

[0034] Reference Figure 2-4 During the melting process in crucible body 1, the heating resistance plate 4 is activated to melt the metal in crucible body 1. After the use of crucible body 1 is completed, the electric valve 32 is opened to discharge the generated waste slag, and the vibration motor 6 is activated to vibrate out the residue in the melting tank 101, improving the efficiency of waste slag cleaning. The waste slag falls into the collection pipe 33 through the slag discharge pipe 31 for collection. After a period of collection, the waste slag fills the collection pipe 33, and the operator can observe the waste slag collection through the observation window 22.

[0035] Reference Figure 2 and Figure 4The lifting motor 9 starts, driving the lifting screw 8 to rotate. Driven by the lifting screw 8 and guided by the guide rod 10, the crucible body 1 moves upward, causing the slag discharge pipe 31 connected to its bottom to move out of the collection pipe 33. The connecting cylinder 5 starts, and the connecting cover plate 12 slides on the collection pipe 33 under the driving action of the connecting cylinder 5 and the limiting guidance of the slider 13 and the sliding groove 332, until the slag collection port 331 is blocked. This reduces the possibility of waste slag in the collection pipe 33 leaking out through the slag collection port 331 during the slag discharge process. The cleaning cylinder 36 starts, driving the cleaning push plate 34 to move in the collection pipe 33. The cleaning push plate 34 pushes out the waste slag in the collection pipe 33, and the sealing ring 35 reduces the possibility of waste slag adhering to the inner wall of the collection pipe 33. The support block 11 provides support and limits the crucible body 1, preventing excessive descent of the crucible body 1 and collision between the bottom end of the slag discharge pipe 31 and the bottom wall of the collection pipe 33.

[0036] The implementation principle of the crucible rapid unloading structure in this embodiment is as follows: When the crucible body 1 is smelting, the heating resistance plate 4 is activated to melt the metal in the crucible body 1. After use, the electric valve 32 is opened to discharge the generated waste slag, and the vibration motor 6 is activated to vibrate out the residue in the smelting tank 101. The waste slag falls into the collection pipe 33 through the slag discharge pipe 31 for collection. The lifting motor 9 is activated, the crucible body 1 moves upward, and drives the slag discharge pipe 31 connected to its bottom to move out of the collection pipe 33. The connecting cover plate 12 seals the slag collection port 331, the cleaning cylinder 36 is activated, and the cleaning push plate 34 moves in the collection pipe 33, pushing out the waste slag in the collection pipe 33.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
