Description

Technical Field

[0001] This invention belongs to the field of smelting technology, and specifically relates to a smelting apparatus and smelting method for recycling waste copper. Background Technology

[0002] Smelting, simply put, is the entire industrial production process of taking raw materials such as ores and scrap metals, heating, melting, and chemically reacting them to remove impurities and purify them, ultimately obtaining pure metals or alloys.

[0003] Smelting equipment is required in the process of recycling and smelting scrap copper. Medium frequency furnace is one of the commonly used smelting equipment. When the scrap copper blocks inside the existing medium frequency furnace are in use, the scrap copper blocks inside are prone to collapse when they lose the support of the scrap copper blocks below during the melting process. This causes the scrap copper blocks to hit the furnace wall, which will damage the furnace wall in the long run and affect the use of the furnace.

[0004] Therefore, it is necessary to invent a smelting device and smelting method for recycling waste copper to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a smelting apparatus and method for recycling waste copper, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A smelting apparatus for recycling scrap copper includes a furnace body, the furnace body having a heating chamber inside, and the heating chamber having an anti-collision component inside, the anti-collision component being able to prevent the molten scrap copper from collapsing and colliding with the inner wall of the heating chamber; The anti-collision assembly includes: a ring plate, a baffle, a base plate, an elongated hole, a swing assembly, and a shielding assembly; The ring plate is positioned above the heating chamber. The baffles are fixedly installed at equal intervals around the bottom of the ring plate. The base plate is connected to the bottom of the multiple baffles. The elongated holes are equally spaced around the base plate. The swinging assembly is mounted on the furnace body to drive the ring plate to swing. The shielding assembly is used to prevent the molten liquid on the baffles from being thrown out of the heating chamber.

[0007] Furthermore, the swinging assembly includes: a ring frame, a support base, a connecting plate, and a rotating assembly; The support base is fixedly installed on the top of the furnace body, the ring frame is rotatably installed inside the support base, the ring frame is fixedly connected to the ring plate through a connecting plate, and the rotating assembly is located on the top of the furnace body to drive the ring frame to rotate rapidly.

[0008] Furthermore, the rotating assembly includes: teeth, a motor, and a gear; The teeth are equidistantly arranged around the top of the ring frame, the motor is fixedly installed on the top of the furnace body, the gear is fixed to the end of the motor's output shaft, and the gear meshes with the teeth.

[0009] Furthermore, the blocking component includes: a retaining ring and an adjustment component; The retaining ring is slidably disposed inside the ring frame, and the adjustment component is disposed on the ring frame for adjusting the position of the retaining ring.

[0010] Furthermore, the adjustment assembly includes: a lead screw and a crank handle; The lead screws are symmetrically rotated and mounted on the ring frame, the retaining rings are threaded onto the outside of the pair of lead screws, and the crank handle is fixedly mounted on the top of the lead screws.

[0011] Furthermore, the gap between adjacent baffles and the area of ​​the elongated hole can both block impurities generated during the smelting process.

[0012] Furthermore, the base plate is slidably sleeved on the outside of the stop rod, and the bottom of the multiple stop rods are jointly fixedly installed with a retaining ring. A pull rod is fixedly installed at the top center of the base plate, and a handle is fixedly installed at the top of the pull rod.

[0013] Furthermore, there is a gap between the base plate, the stop bar, and the heating chamber.

[0014] The present invention also provides a method for smelting using the above-mentioned smelting apparatus for recycling waste copper, comprising the following steps: S1. When using, place the scrap copper block on the bottom plate, turn on the furnace to heat the scrap copper block, and melt the scrap copper block; S2. During the melting process, if the scrap copper block collapses in the area formed by the baffle and the base plate, that is, the scrap copper block below melts and the scrap copper block above loses support and falls, the falling scrap copper block will hit the base plate and will not hit the inner wall of the heating chamber. Therefore, the inner wall of the heating chamber can be protected. The molten liquid flows into the interior of the heating chamber through the elongated hole and the gap between adjacent baffles. S3. After melting is complete, tilt the furnace body to pour out the molten liquid in the heating chamber. During the pouring process, some molten liquid will remain on the baffle and bottom plate. After the furnace body is reset, the ring plate is swung by the swinging component, which in turn swings the baffle and bottom plate, thus throwing the remaining molten liquid onto the inner wall of the heating chamber. During this process, the shielding component can prevent the molten liquid on the baffle from being thrown out of the heating chamber. The molten liquid thrown onto the inner wall of the heating chamber slides down the inner wall of the heating chamber and collects at the bottom of the heating chamber. Then, tilt the furnace body again to pour out this remaining molten liquid. This completes the smelting of scrap copper.

[0015] The technical effects and advantages of this invention are as follows: 1. The present invention, through the anti-collision components, can prevent the upper scrap copper from collapsing and colliding with the inner wall of the heating chamber during the smelting of scrap copper, thus protecting the inner wall of the heating chamber. 2. The present invention can also filter impurities in the molten liquid through the anti-collision component, thereby improving the purity of the molten liquid and facilitating the cleaning of the filtered impurities. This prevents blockage of the long holes and the gaps between adjacent baffles, ensuring normal use of the whole. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] This invention provides a smelting apparatus for recycling waste copper, such as... Figures 1 to 7 As shown, it includes a furnace body 1, which is a medium-frequency furnace in the prior art. The furnace body 1 is provided with a heating chamber 2 inside, and the heating chamber 2 is provided with an anti-collision component inside. The anti-collision component can prevent the molten scrap copper from collapsing and colliding with the inner wall of the heating chamber 2. The anti-collision components include: ring plate 3, baffle 4, base plate 5, elongated hole 6, swing assembly, and shielding assembly; The ring plate 3 is positioned above the heating chamber 2. The baffles 4 are fixedly installed around the bottom of the ring plate 3 at equal intervals. The base plate 5 is connected to the bottom of the multiple baffles 4. The elongated holes 6 are opened around the base plate 5 at equal intervals. The swinging assembly is set on the furnace body 1 to drive the ring plate 3 to swing. The shielding assembly is used to prevent the molten liquid on the baffles 4 from being thrown out of the heating chamber 2.

[0019] In use, place the scrap copper block on the base plate 5, turn on the furnace body 1 to heat the scrap copper block, causing it to melt. During the melting process, if the scrap copper block collapses within the area formed by the baffle 4 and the base plate 5 (i.e., the lower scrap copper block melts and the upper scrap copper block loses support and falls), the falling scrap copper block will impact the base plate 5, not the inner wall of the heating chamber 2, thus protecting the inner wall of the heating chamber 2. The molten liquid flows into the interior of the heating chamber 2 through the elongated hole 6 and the gap between adjacent baffles 4. After melting is complete, tilt the furnace body 1 to pour out the molten liquid in the heating chamber 2. During the pouring process, some molten liquid will remain on the baffle. 4. After the furnace body 1 is reset on the bottom plate 5, the ring plate 3 is swung by the swinging assembly, which in turn swings the baffle 4 and the bottom plate 5, thereby throwing the remaining molten liquid onto the inner wall of the heating chamber 2. During this process, the shielding assembly can prevent the molten liquid on the baffle 4 from being thrown out of the heating chamber 2. The molten liquid thrown onto the inner wall of the heating chamber 2 slides down the inner wall of the heating chamber 2 and collects at the bottom of the heating chamber 2. Then the furnace body 1 is tilted to pour out this part of the remaining molten liquid. Thus, the smelting of scrap copper is completed. During the whole process, the scrap copper above will not collapse and collide with the inner wall of the heating chamber 2 due to the loss of support from the scrap copper below, thus protecting the inner wall of the heating chamber 2.

[0020] like Figures 1 to 3 As shown, the swinging assembly includes: a ring frame 7, a support base 9, a connecting plate 18, and a rotating assembly; The support base 9 is fixedly installed on the top of the furnace body 1, and the ring frame 7 is rotatably installed inside the support base 9. The ring frame 7 is fixedly connected to the ring plate 3 through the connecting plate 18. The rotating component is set on the top of the furnace body 1 to drive the ring frame 7 to rotate rapidly.

[0021] The rotating assembly drives the ring frame 7 to rotate rapidly, along with the connecting plate 18, ring plate 3, baffle 4, and bottom plate 5. This generates centrifugal force, which throws the molten liquid remaining on the baffle 4 and bottom plate 5 onto the inner wall of the heating chamber 2. Under the influence of gravity, the molten liquid moves downward and collects at the bottom of the heating chamber 2. When it is poured out later, because the amount of molten liquid is small, it will not come into contact with the baffle 4 and bottom plate 5, allowing it to be discharged to the outside of the furnace body 1.

[0022] like Figure 1 As shown, the rotating assembly includes: teeth 10, motor 11, and gear 12; The teeth 10 are equidistantly arranged around the top of the ring frame 7, the motor 11 is fixedly installed on the top of the furnace body 1, and the gear 12 is fixed to the end of the output shaft of the motor 11, and the gear 12 meshes with the teeth 10.

[0023] The motor 11 is started so that its output shaft drives the gear 12 to rotate, thereby cooperating with the teeth 10 to drive the ring frame 7 to rotate rapidly.

[0024] like Figures 2 to 3 As shown, the shading assembly includes: a retaining ring 8 and an adjustment assembly; The retaining ring 8 is slidably disposed inside the ring frame 7. Specifically, vertical grooves are symmetrically provided on the ring frame 7, and both ends of the retaining ring 8 are slidably disposed in the vertical grooves. The adjustment component is disposed on the ring frame 7 and is used to adjust the position of the retaining ring 8.

[0025] By adjusting the position of the baffle ring 8, the baffle ring 8 is moved down and extended into the heating chamber 2, but does not contact the inner wall of the heating chamber 2. The baffle ring 8 can block the melt on the baffle 4 near the liquid outlet of the furnace body 1, preventing this part of the melt from being thrown out of the heating chamber 2.

[0026] like Figures 2 to 3 As shown, the adjustment components include: lead screw 13 and crank handle 14; The lead screw 13 is symmetrically rotated and mounted on the ring frame 7. The retaining ring 8 is threaded on the outside of the pair of lead screws 13. The crank handle 14 is fixedly mounted on the top of the lead screw 13. Specifically, the lead screw 13 is rotatably mounted in the vertical groove, and the retaining ring 8 is threaded on the outside of the lead screw 13.

[0027] Rotating a pair of cranks 14 causes the lead screw 13 to rotate in the forward direction, thereby driving the retaining ring 8 to move downward. Conversely, rotating the cranks 14 in the reverse direction can achieve the upward reset of the retaining ring 8.

[0028] like Figure 2 As shown, the gap between adjacent baffles 4 and the area of ​​the elongated hole 6 can both block impurities generated during the smelting process.

[0029] This allows the area formed by the baffle 4 and the base plate 5 to filter impurities, thereby improving the purity of the molten liquid.

[0030] like Figures 2 to 7 As shown, the base plate 5 is slidably sleeved on the outside of the stop bar 4, and the bottom of multiple stop bars 4 are fixedly installed with a retaining ring 15. A pull rod 16 is fixedly installed at the top center of the base plate 5, and a handle 17 is fixedly installed at the top of the pull rod 16.

[0031] Due to long-term use, the gap between adjacent baffles 4 and the elongated hole 6 will be filled with impurities, which will affect the outflow of the melt. Therefore, after each use, by pulling the handle 17, the pull rod 16 and the base plate 5 are raised, thereby driving the impurities upward. Finally, the base plate 5 is located outside the heating chamber 2. At this time, the impurities scraped from the elongated hole 6 and the baffle 4 by the base plate 5 can be cleaned, so as to avoid the gap between the elongated hole 6 and the adjacent baffle 4 being blocked, and to ensure the normal use of the whole.

[0032] like Figure 2 As shown, there is a gap between the base plate 5, the stop bar 4 and the heating chamber 2.

[0033] This ensures that the molten liquid cleaned from the baffle 4 and the base plate 5 does not come into contact with the baffle 4 and the base plate 5 again when it leaves the heating chamber 2.

[0034] The components within the anti-collision assembly are all made of high-chromium-nickel heat-resistant cast steel.

[0035] The method of smelting using the smelting equipment for scrap copper recycling described above includes the following steps: Working Principle: During use, place the scrap copper block onto the base plate 5, turn on the furnace body 1 to heat the scrap copper block, causing it to melt. During the melting process, if the scrap copper block collapses within the area formed by the baffle 4 and the base plate 5 (i.e., the lower scrap copper block melts and the upper scrap copper block loses support and falls), the falling scrap copper block will impact the base plate 5, not the inner wall of the heating chamber 2, thus protecting the inner wall of the heating chamber 2. The molten liquid flows into the interior of the heating chamber 2 through the elongated hole 6 and the gap between adjacent baffles 4. After melting is complete, tilt the furnace body 1 to pour out the molten liquid in the heating chamber 2. During the pouring process, some molten liquid will remain on the baffle 4 and the base plate 5. After resetting the furnace body 1, rotate a pair of crank handles 14 to rotate the lead screw 13 clockwise, thereby driving the retaining ring 8 downwards, extending it into the heating chamber 2 without contacting the inner wall of the heating chamber 2. Start the motor 11... The output shaft drives the gear 12 to rotate, which in turn drives the ring frame 7 to rotate rapidly in conjunction with the gear 10. The ring frame 7, along with the connecting plate 18, ring plate 3, baffle 4, and bottom plate 5, rotates rapidly, causing the centrifugal force generated to throw the molten liquid remaining on the baffle 4 and bottom plate 5 onto the inner wall of the heating chamber 2. Under the action of gravity, the molten liquid moves down and collects at the bottom of the heating chamber 2. The baffle ring 8 can block the molten liquid on the baffle 4 near the outlet of the furnace body 1, preventing this part of the molten liquid from being thrown out of the heating chamber 2. Finally, the molten liquid on the baffle ring 8 also falls back into the heating chamber 2 under the action of gravity. Then, the motor 11 is stopped, and a pair of cranks 14 are reversed. Conversely, the baffle ring 8 is moved up and reset. Then, the furnace body 1 is tilted to pour out the remaining molten liquid. Thus, the smelting of scrap copper is completed. During the whole process, the scrap copper above will not collapse and collide with the inner wall of the heating chamber 2 due to the loss of support from the scrap copper below, thus protecting the inner wall of the heating chamber 2. During the smelting process, the area formed by the baffle 4 and the base plate 5 can also filter impurities, thereby improving the purity of the molten liquid. Due to long-term use, the gap between adjacent baffles 4 and the elongated hole 6 will be filled with impurities, which will affect the outflow of the molten liquid. Therefore, after each use, by pulling the handle 17, the pull rod 16 and the base plate 5 are raised, thereby driving the impurities upward. Finally, the base plate 5 is located outside the heating chamber 2. At this time, the impurities scraped from the elongated hole 6 and the baffle 4 by the base plate 5 can be cleaned, so as to avoid the gap between the elongated hole 6 and the adjacent baffle 4 being blocked, and to ensure the normal use of the whole.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
