Description

Technical Field

[0001] This invention relates to the field of metal refining technology, specifically to an integrated device for continuous melting and casting of copper-based alloys. Background Technology

[0002] Copper-based alloys, with their excellent electrical conductivity, thermal conductivity, corrosion resistance, and processing performance, have long been used as core basic materials in high-end manufacturing fields such as electronics and information, new energy, and aerospace. They are widely used in key components such as high-frequency busbars for 5G communication base stations, rotors for drive motors in new energy vehicles, precision connectors for aerospace, and high-current-carrying conductors for smart grids.

[0003] Traditional copper-based alloy production uses a segmented process of "melting-transfer-casting": the melting stage involves preparing molten metal through induction furnace, reverberatory furnace or electric arc furnace, and then transferring it (such as by overhead crane or trough conveyor) to casting equipment (semi-continuous casting machine, sand mold) for shaping. However, due to the separation of the melting and casting stages, the molten metal is exposed to air for a long time, which makes it prone to oxidation or hydrogen / nitrogen absorption, resulting in defects such as porosity and inclusions inside the cast billet. For example, the swing-type copper alloy melting and casting equipment with patent number CN205676523U uses a swing mechanism to tilt the furnace body at a certain angle, which facilitates the outflow of liquid copper. However, it only focuses on the casting process and does not closely integrate the melting and casting processes. This can easily prolong the path and time that the molten metal is exposed to air. In addition, it lacks pretreatment of the alloy solution before casting, making it difficult to ensure the stability of the alloy solution quality before casting, which greatly affects the internal quality of the cast billet. Summary of the Invention

[0004] The purpose of this invention is to achieve efficient and continuous operation of copper-based alloy smelting and casting through an integrated "stirring-docking-fine filtration-casting" system. This ensures uniform melting of raw materials, rapid switching between smelting and casting states via a bidirectional docking mechanism, and improved filtration efficiency and bubble suppression through multiple filtration and intermittent lifting mechanisms. This ensures the purity of the billet composition and meets the needs of continuous production of copper-based alloys.

[0005] The objective of this invention can be achieved through the following technical solution: an integrated device for continuous melting and casting of copper-based alloys, comprising a positioning frame, a melting furnace and a casting furnace, wherein the melting furnace is set in the middle section inside the positioning frame via a base, and the casting furnace is set in the bottom section inside the positioning frame, and a bidirectional docking mechanism is provided between the melting furnace and the casting furnace. The furnace top cover of the smelting furnace is vertically connected with a stirring rod, and the top of the stirring rod extends into the interior of the furnace top. A drive wheel is fixedly installed on the outside of the stirring rod at the top of the smelting furnace. Several sets of stirring blades are staggered on the outside of the stirring rod inside the smelting furnace. A conical base is rotatably connected to the bottom of the stirring rod.

[0006] Furthermore, a single-axis motor is installed on the top inner wall of the positioning frame adjacent to the smelting furnace, and a rotating rod is fixedly installed at the bottom of the single-axis motor. A main drive wheel is longitudinally slidably sleeved on the outside of the rotating rod at a position flush with the driven wheel. The main drive wheel slides with the vertical groove on the outer wall of the rotating rod through a slider provided on the inner ring wall. A drive belt is sleeved between the main drive wheel and the driven wheel.

[0007] Furthermore, a material guide pipe is vertically installed inside the casting furnace, and a filter screen plate is fixedly installed on the top of the material guide pipe. The top of the material guide pipe is fixedly installed through the bottom frame of the positioning frame, and the outside of the material guide pipe is set in a curved mesh surface at the bottom inner wall of the casting furnace. A fine filtration mechanism is provided at the furnace opening at the top of the casting furnace.

[0008] Furthermore, the bottom plate of the conical chassis is adapted to the bottom opening of the smelting furnace, and a splash guard is fixedly installed at the bottom of the smelting furnace. The inner diameter of the splash guard is 3 cm larger than the inner diameter of the smelting furnace and the outer diameter of the bottom of the conical chassis.

[0009] Furthermore, the bidirectional docking mechanism includes a dual-axis motor, which is located at the middle of the inner wall of one side of the positioning frame. The upper and lower output shafts of the dual-axis motor are fixedly equipped with spiral guide rods with opposite threads. The outer ends of the two sets of spiral guide rods away from the dual-axis motor are respectively spirally sleeved with concave abutment frame one and concave abutment frame two.

[0010] Furthermore, the concave abutment frame is sleeved on the outside of the stirring rod and the rotating rod, the main drive wheel and the driven drive wheel are respectively fixedly installed inside the concave abutment frame one, and the concave abutment frame two is fixedly installed at the bottom surface of the casting furnace.

[0011] Furthermore, a vertical toothed roller is fixedly sleeved at the bottom of the rotating rod, and an annular toothed ring is meshed with the adjacent part of the vertical toothed roller. The annular toothed ring is rotatably connected to the middle section outside the casting furnace, and triangular abutments are fixedly installed at equal intervals on the top surface of the annular toothed ring.

[0012] Furthermore, a vertical toothed roller is fixedly sleeved at the bottom of the rotating rod, and an annular toothed ring is meshed with the adjacent part on one side of the vertical toothed roller. The annular toothed ring is rotatably connected to the middle section outside the casting furnace, and triangular abutments are fixedly installed at equal intervals on the top surface of the annular toothed ring. The annular toothed ring is connected to the intelligent control module, which includes a bubble sensor and a microprocessor. The bubble sensor is embedded in the mesh of the fine filter cartridge to monitor the concentration of bubbles in the molten liquid in real time. The microprocessor dynamically adjusts the lifting frequency of the triangular abutment based on the sensor data.

[0013] Furthermore, the fine filtration mechanism includes a fine filter cylinder that is movably inserted into the furnace opening at the top of the casting furnace. The inner diameter of the fine filter cylinder opening is 3 cm larger than the outer diameter of the conical base, and the outer diameter of the fine filter cylinder is 2 cm smaller than the inner diameter of the anti-splash cover. The bottom of the fine filter cylinder is set with a mesh structure and inserted into the casting furnace. A limiting ring is fixedly sleeved on the outside of the fine filter cylinder at the furnace opening at the top of the casting furnace. Several sets of spring damping shock absorbers are arranged at equal distances between the top surface of the limiting ring and the bottom of the anti-splash cover.

[0014] Furthermore, several sets of abutment shafts are fixedly installed at equal intervals on the bottom of the limiting ring and outside the casting furnace via uprights. The bottom of the several sets of abutment shafts is in contact with the surface of the annular toothed ring, and the several sets of abutment shafts are staggered with several sets of triangular abutment blocks.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes components such as a stirring rod, where a drive wheel rotates along with the main drive wheel, driving the stirring rod to rotate. The stirring blades on the stirring rod thoroughly stir the copper-based alloy raw materials in the smelting furnace, ensuring uniform heating of the alloy raw materials and improving smelting efficiency. Simultaneously, the conical base at the bottom of the stirring rod scrapes the bottom of the smelting furnace, effectively preventing the alloy raw materials from clumping at the bottom of the smelting furnace and ensuring smelting quality.

[0016] The present invention also incorporates a bidirectional docking mechanism. A dual-axis motor drives the spiral guide rods on the upper and lower output shafts to rotate, causing the first and second concave abutment frames to move in opposite directions. The first abutment frame pushes the stirring rod and the rotating rod towards the casting furnace. At this time, the conical base plate disengages from the inside of the melting furnace, allowing the molten alloy liquid to be smoothly discharged to the casting furnace. The inclined design of the conical base plate helps to slow down the flow of the molten metal, further ensuring the smooth progress of the melting process and realizing the conversion between melting and casting.

[0017] This invention also incorporates a fine filtration mechanism with a dual mechanism of filtration and intermittent operation. Through intermittent lifting, the filter screen is forced to perform preliminary filtration on the smelted copper-based alloy. Simultaneously, a single-axis motor drives the vertical toothed roller and annular toothed ring, while the triangular abutment block lifts the abutment shaft, achieving intermittent lifting of the fine filter cylinder. This further prevents the formation of air bubbles inside the smelted copper-based alloy. Furthermore, the mesh structure at the bottom of the fine filter cylinder allows for secondary filtration of the smelted copper-based alloy, further improving its purity. Attached Figure Description

[0021] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 - Figure 4 As shown, a copper-based alloy continuous melting and casting integrated device includes a positioning frame 1, a melting furnace 2 and a casting furnace 3. The melting furnace 2 is set in the middle section inside the positioning frame 1 via a base, and the casting furnace 3 is set in the bottom of the positioning frame 1. A bidirectional docking mechanism 4 is provided between the melting furnace 2 and the casting furnace 3. A stirring rod 201 is vertically installed through the top of the furnace cover of the smelting furnace 2, and the top of the stirring rod 201 extends into the top interior of the smelting furnace 2. A drive wheel 202 is fixedly installed on the outside of the stirring rod 201 and at the top of the smelting furnace 2. Several sets of stirring blades are staggered on the outside of the stirring rod 201 and inside the smelting furnace 2. A conical base 203 is rotatably connected to the bottom of the stirring rod 201. The bottom plate of the conical base 203 is adapted to the bottom opening of the smelting furnace 2. A splash guard 204 is fixedly installed at the bottom of the smelting furnace 2. The inner diameter of the splash guard 204 is 3 cm larger than the inner diameter of the smelting furnace 2 and the bottom outer diameter of the conical base 203. A single-axis motor 101 is installed on the top inner wall of the positioning frame 1 adjacent to the melting furnace 2, and a rotating rod 102 is fixedly installed at the bottom of the single-axis motor 101. A main drive wheel 103 is longitudinally slidably sleeved on the outside of the rotating rod 102 at a position flush with the driven drive wheel 202. The main drive wheel 103 slides with the vertical groove on the outer wall of the rotating rod 102 through a slider provided on the inner ring wall. A drive belt is sleeved between the main drive wheel 103 and the driven drive wheel 202. A guide pipe 301 is vertically installed inside the casting furnace 3, and a filter screen plate 302 is fixedly installed on the top of the guide pipe 301. The top of the guide pipe 301 is fixedly installed through the bottom frame of the positioning frame 1, and the outside of the guide pipe 301 is set as a curved mesh surface on the bottom inner wall of the casting furnace 3. In practice, the copper-based alloy raw material is first placed into the smelting furnace 2. The single-shaft motor 101 is started and drives the main drive wheel 103 to rotate through the rotating rod 102. Since the main drive wheel 103 and the driven wheel 202 are connected by a transmission belt, the driven wheel 202 will rotate accordingly, thereby driving the stirring rod 201 to rotate. The stirring rod 201 drives its external stirring blades to stir the copper-based alloy raw material in the smelting furnace 2. At the same time, the conical base plate 203 at the bottom of the stirring rod 201 scrapes the material from the bottom of the smelting furnace 2 to prevent the copper-based alloy raw material from clumping at the bottom of the smelting furnace 2. The bidirectional docking mechanism 4 includes a dual-axis motor 41, which is located at the middle of the inner wall of one side of the positioning frame 1. The upper and lower output shafts of the dual-axis motor 41 are fixedly installed with spiral guide rods 42 with opposite threads. The outer ends of the two sets of spiral guide rods 42 away from the dual-axis motor 41 are respectively spirally sleeved with concave abutment frame one 43 and concave abutment frame two 44. Concave abutment frame one 43 is sleeved on the outside of the stirring rod 201 and the rotating rod 102. The main drive wheel 103 and the driven drive wheel 202 are respectively fixedly installed inside the concave abutment frame one 43. Concave abutment frame two 44 is fixedly installed at the bottom of the casting furnace 3. After melting is completed, the dual-shaft motor 41 is started, driving the upper and lower spiral guide rods 42 to rotate in opposite directions. This drives the concave abutment frame 1 43 and concave abutment frame 2 44 to move towards each other. The concave abutment frame 1 43 pushes the stirring rod 201 and the rotating rod 102 towards the casting furnace 3. At this time, the conical base 203 detaches from the interior of the melting furnace 2 and moves into the anti-splash cover 204, facilitating the smooth discharge of the molten alloy to the casting furnace 3. The anti-splash cover 204 reduces molten splashing, and the inclined design of the conical base 203 helps to slow the flow of the molten metal. Copper-based alloy raw materials fall into the casting furnace 3 through the feed pipe 301. Since the feed pipe 301 is set with a curved mesh surface on the inner wall of the bottom of the casting furnace 3, it can help the alloy liquid that has been filtered through multiple layers to be smoothly discharged from the feed pipe 301 and thus realize casting. This is conducive to the realization of continuous melting and casting integrated operation of copper-based alloys.

[0023] Example 2: Please refer to Figure 2 - Figure 7 As shown, a vertical toothed roller 104 is fixedly sleeved at the bottom of the rotating rod 102, and an annular toothed ring 105 is meshed with the vertical toothed roller 104 on one side. The annular toothed ring 105 is rotatably connected to the middle section outside the casting furnace 3, and triangular abutments 106 are fixedly installed at equal intervals on the top surface of the annular toothed ring 105. A fine filtration mechanism 5 is provided at the top of the casting furnace 3. The fine filtration mechanism 5 includes a fine filter cylinder 51 that is movably inserted into the top of the casting furnace 3. The inner diameter of the fine filter cylinder 51 is 3 cm larger than the outer diameter of the conical base 203, and the outer diameter of the fine filter cylinder 51 is 2 cm smaller than the inner diameter of the anti-splash cover 204. The bottom of the fine filter cylinder 51 is set with a mesh structure and inserted into the casting furnace 3. A limiting ring 52 is fixedly sleeved on the outside of the fine filter cylinder 51 at the top of the casting furnace 3. Several sets of spring damping shock absorbers 53 are arranged at equal distances between the top surface of the limiting ring 52 and the bottom of the anti-splash cover 204. Several sets of abutment shafts 54 are fixedly installed at equal distances on the bottom of the limiting ring 52 and outside the casting furnace 3 by uprights. The bottom of the several sets of abutment shafts 54 contacts the surface of the annular toothed ring 105. The several sets of abutment shafts 54 are offset from the several sets of triangular abutment blocks 106. Before the molten material is fed into the casting furnace 3, the molten alloy is first received by the fine filter cylinder 51 and the solid residue in the molten alloy is initially filtered by the filter screen. The molten alloy after the initial filtration is then introduced into the casting furnace 3 and is received and filtered again by the filter screen plate 302. Since the surface mesh of the filter screen plate 302 is smaller than the mesh at the bottom of the fine filter cylinder 51, fine filtration is achieved, effectively removing air bubbles in the molten alloy and ensuring the quality of the casting billet. Meanwhile, during its rotation, the single-axis motor 101 drives the vertical toothed roller 104 to rotate. The vertical toothed roller 104 meshes with the annular toothed ring 105, thereby realizing the rotation of the annular toothed ring 105 and driving several sets of triangular abutments 106 to rotate. Through the alternating pressure of the inclined plane against the abutment shaft 54, the fine filter cartridge 51 is intermittently raised. When the abutment shaft 54 ​​passes the triangular abutment block 106, it sinks. The fine filter cartridge 51 drives the limiting ring 52 to move up and down synchronously, and forces the spring damping shock absorber ring 53 between the limiting ring 52 and the anti-splash cover 204 to compress and reset. This helps to improve the stability of the fine filter cartridge 51 during the alloy liquid casting process and reduce shaking. At the same time, the setting of the spring damping shock absorber ring 53 can also absorb the vibration generated during the casting process, further reducing the fluctuation of the alloy liquid during casting, ensuring that the alloy liquid can be smoothly and evenly introduced into the casting furnace 3, avoiding undesirable phenomena such as splashing and spraying of the alloy liquid during the casting process, and improving casting efficiency and casting quality.

[0024] This process is repeated to achieve intermittent lifting of the fine filter cartridge 51. The pressure on the surface of the filter screen plate 302 changes continuously, which helps to accelerate the overflow of bubbles from the alloy liquid and promotes the flow of the alloy liquid through the filter screen plate 302, thereby improving the filtration efficiency. In addition, the intermittent lifting of the fine filter cartridge 51 can also effectively prevent the filter screen plate 302 from clogging and extend its service life. It is worth mentioning that the annular toothed ring 105 is connected to the intelligent control module, which includes a bubble sensor and a microprocessor. The bubble sensor is embedded in the mesh of the fine filter cartridge 51 to monitor the concentration of bubbles in the melt in real time. The microprocessor dynamically adjusts the lifting frequency of the triangular abutment block 106 based on the sensor data.

[0025] Working principle: First, copper-based alloy raw materials are put into the melting furnace 2. The raw materials are melted into alloy liquid at high temperature in the melting furnace 2. At this time, the single-shaft motor 101 is started, and its output shaft drives the rotating rod 102 to rotate. The rotating rod 102 then drives the main drive wheel 103 to rotate synchronously. Since the main drive wheel 103 and the driven wheel 202 are connected by a transmission belt, the driven wheel 202 will also rotate. This drives the stirring rod 201 to rotate in the melting furnace 2. The stirring blades on the outside of the stirring rod 201 then fully stir the alloy liquid to ensure that the alloy liquid is heated evenly and to prevent the alloy liquid from clumping or depositing in the melting furnace 2. During the stirring process, the conical base plate 203 at the bottom of the stirring rod 201 scrapes the bottom of the melting furnace 2 to ensure that the molten alloy can be smoothly discharged from the bottom of the melting furnace 2. After the melting is completed, the dual-shaft motor 41 starts, and its upper and lower output shafts drive the spiral guide rod 42 to rotate in opposite directions. The rotation of the spiral guide rod 42 drives the concave abutment frame 1 43 and concave abutment frame 2 44 to move towards each other. The concave abutment frame 1 43 pushes the stirring rod 201 and the rotating rod 102 to move towards the casting furnace 3. At this time, the conical base plate 203 gradually leaves the interior of the melting furnace 2 and moves into the anti-splash cover 204. This design helps the molten alloy to be smoothly discharged to the casting furnace 3. At the same time, the anti-splash cover 204 can effectively reduce the splashing of molten liquid. After passing through the anti-splash cover 204, the molten alloy falls into the casting furnace 3 through the guide pipe 301. The curved mesh design on the outside of the guide pipe 301 helps the molten alloy to be discharged smoothly and to achieve casting. During the casting process, the fine filtration mechanism 5 plays an important role. The fine filter cylinder 51 receives the molten alloy discharged from the melting furnace 2 and performs preliminary filtration of the solid residue in the molten alloy through the filter screen at its bottom. The molten alloy after preliminary filtration is then introduced into the casting furnace 3 and is further finely filtered by the filter plate 302. This dual filtration design ensures the purity of the molten alloy and improves the quality of the cast billet.
