Description

Technical Field

[0001] This utility model relates to a pressure roller transmission mechanism, and in particular to a melt heat preservation device for electrolytic copper processing, belonging to the field of electrolytic copper processing technology. Background Technology

[0002] In the electrolytic copper processing, an tundish is used. The tundish plays a crucial buffering role. Its function is to receive the molten copper continuously flowing from the refining furnace and then pouring it into the next stage. The flow rate and temperature of the molten copper entering the tundish may fluctuate to some extent.

[0003] In the prior art, such as the utility model with application number 201020221695.3, a quantitative casting tundish for copper anode plates is disclosed. It has a simple structure, is easy to operate, and requires little space for installation. The height difference from the copper outlet to the anode mold only needs to be 1.3 meters for installation. The tundish can be tilted at different angles and can stop at two different angles, which slows down the outflow of molten copper. Charcoal can be covered on the surface of the molten copper to isolate it from the air, slow down the trend of secondary oxidation, and also to keep it warm and reduce heat loss.

[0004] The above-mentioned applications still have shortcomings:

[0005] The top of this type of copper anode plate quantitative casting tundish is open. The surface of the molten copper in electrolytic processing has a large contact area with the air. When the copper molten copper is poured into the interior, the open entrance will emit a large amount of radiant heat, resulting in heat loss and poor heat preservation. Although charcoal can be used to cover the tundish to isolate the air and keep it warm, the charcoal will form carbon ash impurities, affecting the quality of the electrolytic copper product. In addition, it will increase the consumption of charcoal, making it inconvenient to use and difficult to operate.

[0006] To address these issues, a melt holding device for electrolytic copper processing was designed. Utility Model Content

[0007] The main objective of this invention is to provide a melt heat preservation device for electrolytic copper processing, so as to solve the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A melt insulation device for electrolytic copper processing includes an tundish body with an insulation layer installed inside. A conical cylinder is provided on the top of the tundish body, and an installation mechanism is provided between the tundish body and the conical cylinder. Outlets are provided on both sides of the conical cylinder, and discharge structures are provided on both sides of the conical cylinder at the outlets. A limit sleeve is fixed on the top of the conical cylinder, and a guide cylinder is movably connected inside the limit sleeve. A bolt is provided between the limit sleeve and the guide cylinder. A filter cylinder is fixed at the bottom of the guide cylinder, and the filter cylinder penetrates and extends into the interior of the tundish body. Through holes are uniformly provided on the filter cylinder.

[0010] Preferably, the discharge structure includes a discharge frame and a rotating shaft. The discharge frame is located on both sides of the conical cylinder and is connected to the outlet. The rotating shaft is fixed inside the discharge frame. A movable plate is rotatably installed on the outside of the rotating shaft. A counterweight is installed through the bottom of the movable plate. Limit plates are fixed on the outside of the movable plate, and one side of the limit plate is movably connected to one end of the discharge frame.

[0011] Preferably, the installation mechanism includes a retaining ring one, a limiting ring and a retaining ring two. The retaining ring one is located on the top side wall of the intermediate package body, the retaining ring two is located on the bottom side wall of the conical cylinder, and bolts two are evenly installed between the retaining ring one and the retaining ring two. The limiting ring is located on the inner side wall of the conical cylinder, and the bottom of the limiting ring is in contact with the top of the insulation layer.

[0012] Preferably, the inner bottom wall of the discharge frame is provided with a guide groove, and the guide groove is a V-shaped groove.

[0013] Preferably, the guide tube is a V-shaped tube, and a buffer layer is provided inside the guide tube.

[0014] Preferably, the bottom length of the movable plate is less than the length of the limiting plate, and the bottom shape of the movable plate matches the shape of the guide channel.

[0015] Preferably, the bottom of the limiting ring is provided with a buffer ring, and the bottom of the buffer ring is set as an inclined surface.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the combined use of the tundish body, conical cylinder, limiting sleeve, guide cylinder, bolt, outlet, filter cylinder, through hole, and insulation layer, can add a guide cylinder and conical cylinder at the top inlet of the tundish body. This reduces the contact area between air and melt while facilitating melt flow, thus reducing heat loss and oxidation. Furthermore, the bolt and limiting sleeve facilitate the disassembly of the guide cylinder and filter cylinder, making it more flexible to use. This improves the insulation performance and flexibility of the melt insulation device for electrolytic copper processing.

[0018] 2. This utility model utilizes the combined use of a discharge structure, discharge frame, rotating shaft, movable plate, counterweight, limiting plate, and guide channel. When the tundish body is tilted to one side to pour out the melt, the tundish body drives the conical cylinder to tilt to one side. Under the gravity of the counterweight, the movable plate rotates outward around the axis of the rotating shaft. The more the tundish body tilts, the greater the rotation angle of the movable plate, resulting in a larger melt flow rate. This further reduces the contact area between the melt and air at the outlet. When not tilted, the movable plate seals the discharge frame under the gravity of the counterweight, preventing air from entering and improving the heat preservation effect on the melt at the outlet.

[0019] 3. This utility model utilizes the combined use of retaining ring one, retaining ring two, bolt two, and limiting ring. Bolt two is removed sequentially from between retaining ring one and retaining ring two. Then, the conical cylinder and retaining ring one are lifted upwards, causing retaining ring one to drive the limiting ring upwards simultaneously. After the intermediate tundish body and the conical cylinder are separated, the insulation layer inside the intermediate tundish body can be replaced or the internal structure of the intermediate tundish body can be maintained, thereby improving the overall flexibility and facilitating the maintenance work of the staff.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes a melt insulation device for electrolytic copper processing, including a tundish body 1, an insulation layer 11 installed inside the tundish body 1, a conical cylinder 2 provided on the top of the tundish body 1, an installation mechanism 10 provided between the tundish body 1 and the conical cylinder 2, outlets 7 opened on both sides of the conical cylinder 2, a discharge structure 3 provided on both sides of the conical cylinder 2 and located at the outlets 7, a limiting sleeve 4 fixed on the top of the conical cylinder 2, a guide cylinder 5 movably connected inside the limiting sleeve 4, a bolt 6 provided between the limiting sleeve 4 and the guide cylinder 5, a filter cylinder 8 fixed at the bottom of the guide cylinder 5, and the filter cylinder 8 penetrates and extends into the interior of the tundish body 1, with through holes 9 evenly opened on the filter cylinder 8.

[0036] The guide tube 5 is inserted into the limiting sleeve 4, and the filter tube 8 at the bottom of the guide tube 5 is inserted into the interior of the tundish body 1, so that the bottom end of the filter tube 8 is attached to the inner bottom wall of the tundish body 1. The guide tube 5 is installed and fixed on the limiting sleeve 4 by the bolt 6 on the limiting sleeve 4. The copper melt for electrolytic copper processing is poured from the guide tube 5 into the filter tube 8. The slag in the melt is filtered through the through hole 9. The melt is separated and stored in the filter tube 8 and the space between the filter tube 8 and the tundish body 1. The filter tube 8, which is smaller than the top diameter of the tundish body 1, reduces the contact area between the air and the surface of the melt. The conical tube 2, in conjunction with the guide tube 5, forms a sealed connection to avoid direct contact between the melt and the air between the filter tube 8 and the conical tube 2, thereby reducing heat loss and improving heat preservation performance.

[0037] Example 2

[0038] The solution in Example 1 will be further described below with reference to its specific working method.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, the discharge structure 3 further includes a discharge frame 301 and a rotating shaft 302. The discharge frame 301 is located on both sides of the conical cylinder 2 and is connected to the outlet 7. The rotating shaft 302 is fixed inside the discharge frame 301. A movable plate 303 is rotatably installed on the outside of the rotating shaft 302. A counterweight 304 is installed through the bottom of the movable plate 303. A limit plate 305 is fixed on the outside of the movable plate 303, and one side of the limit plate 305 is movably connected to one end of the discharge frame 301.

[0040] When the tundish body 1 is lifted as a whole by external equipment and tilted to one side to pour out the melt, the tundish body 1 begins to tilt, causing the tundish body 1 to drive the conical cylinder 2 to tilt to one side. Under the gravity of the counterweight 304 and the rotational connection between the movable plate 303 and the rotating shaft 302, the movable plate 303 rotates outward around the axis of the rotating shaft 302. The more the tundish body 1 tilts, the greater the rotation angle of the movable plate 303 becomes, and the greater the outward flow of the melt. This further reduces the contact area between the melt and the air at the outlet 7. When not tilted, the movable plate 303 seals the discharge frame 301 under the gravity of the counterweight 304, preventing air from entering and reducing heat loss and oxidation.

[0041] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the installation mechanism 10 further includes a first retaining ring 101, a limiting ring 104, and a second retaining ring 102. The first retaining ring 101 is located on the top side wall of the intermediate package body 1, the second retaining ring 102 is located on the bottom side wall of the conical cylinder 2, and bolts 2 103 are evenly installed between the first retaining ring 101 and the second retaining ring 102. The limiting ring 104 is located on the inner side wall of the conical cylinder 2, and the bottom of the limiting ring 104 is in contact with the top of the insulation layer 11.

[0042] Remove bolt 103 from between retaining ring 101 and retaining ring 102 in sequence. Then lift the conical cylinder 2 and retaining ring 101 upwards, so that retaining ring 101 drives the limiting ring 104 upwards at the same time. After the intermediate tundish body 1 and the conical cylinder 2 are separated, the insulation layer 11 inside the intermediate tundish body 1 can be replaced or the interior of the intermediate tundish body 1 can be maintained.

[0043] like Figure 3 As shown, in a preferred embodiment, based on the above method, the inner bottom wall of the discharge frame 301 is provided with a guide groove 306, and the guide groove 306 is a V-shaped groove.

[0044] The V-shaped guide groove 306 makes it easier for the poured melt to be discharged outward, thus providing better flow guidance.

[0045] like Figure 1 As shown, in a preferred embodiment, based on the above method, the guide tube 5 is further a V-shaped tube, and a buffer layer is provided inside the guide tube 5.

[0046] The V-shaped guide tube 5 can better collect the melt into the interior of the tundish body 1, and the buffer layer can reduce the impact loss on the guide tube 5.

[0047] like Figure 3 As shown, in a preferred embodiment, based on the above method, the bottom length of the movable plate 303 is less than the length of the limiting plate 305, and the bottom shape of the movable plate 303 matches the shape of the guide groove 306.

[0048] The limiting plate 305, which is longer than the movable plate 303, is used to make the limiting plate 305 fit against the outside of the discharge frame 301, and the bottom of the movable plate 303 matches the shape of the guide channel 306 so that the two fit better and improve the sealing.

[0049] like Figure 1 As shown, in a preferred embodiment, based on the above method, a buffer ring is further provided at the bottom of the limiting ring 104, and the bottom of the buffer ring is set as an inclined surface.

[0050] The buffer ring and the inclined bottom surface reduce the impact of the melt on the limiting ring 104.

[0051] Example 3

[0052] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0053] The guide tube 5 is inserted into the limiting sleeve 4, and the filter tube 8 at the bottom of the guide tube 5 is inserted into the interior of the tundish body 1, so that the bottom end of the filter tube 8 is attached to the inner bottom wall of the tundish body 1. The guide tube 5 is installed and fixed on the limiting sleeve 4 by bolts 6. The copper melt for electrolytic copper processing is poured from the guide tube 5 into the filter tube 8. The slag in the melt is filtered through the through hole 9. The melt is separated and stored in the filter tube 8 and the space between the filter tube 8 and the tundish body 1. The filter tube 8, which is smaller than the top diameter of the tundish body 1, reduces the contact area between the air and the surface of the melt. The conical tube 2, in conjunction with the guide tube 5, forms a sealed connection to avoid direct contact between the melt and the air between the filter tube 8 and the conical tube 2, reducing heat loss and improving heat preservation performance. When the tundish body 1 is lifted as a whole by external equipment and tilted to one side to pour out the melt, the tundish body 1 begins to tilt, causing the tundish body 1 to move. The conical cylinder 2 tilts to one side. Under the gravity of the counterweight 304 and the rotational connection between the movable plate 303 and the rotating shaft 302, the movable plate 303 flips outward around the axis of the rotating shaft 302. The more the tundish body 1 tilts, the greater the flipping angle of the movable plate 303 becomes, and the greater the outward flow of the melt. This further reduces the contact area between the melt and air at the outlet 7. When not tilted, the movable plate 303 seals the discharge frame 301 under the gravity of the counterweight 304, preventing air from entering and reducing heat loss and oxidation. The bolt 103 is removed from the retaining ring 101 and retaining ring 102 in sequence. Then, the conical cylinder 2 and retaining ring 101 are lifted upward, causing retaining ring 101 to drive the limiting ring 104 upward at the same time. After the tundish body 1 and the conical cylinder 2 are separated, the insulation layer 11 inside the tundish body 1 can be replaced or the interior of the tundish body 1 can be maintained.

[0054] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
