Description

Technical Field

[0001] The present invention relates to the technical field of waste copper recycling for valves, and particularly to an annealing device for rolling in waste copper smelting and treatment. Background Art

[0002] The valve material is usually made of iron, and its valve usually adopts a copper valve core. In the prior art, for environments with higher corrosion resistance requirements, super ferritic can be selected and used with a copper valve core. After the valve life is reached, it involves recycling and treatment. After the copper valve core is taken out, the waste copper needs to be smelted and then rolled. During the rolling process, the metal will undergo cold work hardening. Therefore, it is necessary to anneal the waste copper to eliminate cold work hardening and restore the ductility of the metal so that it can be processed continuously.

[0003] In the prior art, the working mode of the annealing furnace adopts a batch loading and unloading method, pulling out and feeding into the annealing furnace the rack loaded with a large amount of materials. Although it can improve the efficiency to a certain extent, the opening time of the annealing furnace is long, wasting a lot of heat energy. Moreover, pulling out and feeding the material rack into the annealing furnace often requires relying on special artificial equipment. In addition, during the operation process, if there is a delay or a failure of the transportation equipment, it may cause the materials not to be fed into the annealing furnace in time, resulting in a shortage of materials in the annealing furnace, thus affecting the production rhythm.

[0014] Optionally, two auxiliary clamping rods are arranged on one side surface of the carrier plate. The auxiliary clamping rods and the movable clamping rods are provided with empty slots at equal intervals.

[0015] Compared with the prior art, the present invention has the following advantages: 1. A buffer assembly is arranged on the side surface of the annealing box of the present invention. The buffer assembly is composed of two closed discs and a carrier plate. A driving assembly is arranged on the top of the annealing box to drive the carrier plate to rotate. Fixing assemblies are arranged on both side surfaces of the carrier plate of the buffer assembly. The fixing assemblies can fix a plurality of rolled copper strips. The rolled copper strips of the buffer assembly inside the annealing box are annealed inside the annealing box. At the same time, the fixing assemblies of the buffer assembly on the outer side surface of the annealing box can buffer and receive the rolled copper strips from the rolling equipment. After the copper strips in the annealing box are annealed, new copper strips can be immediately replaced, reducing the material changing time and improving the production efficiency. In addition, in the traditional method, the annealed copper strips need to be taken out first and then new copper strips are put in, resulting in a long downtime of the equipment. The design of the buffer assembly can prepare the next batch of materials during the annealing process to achieve seamless connection. Finally, the buffer assembly can reduce the opening time of the annealing box, keep the temperature inside the box stable, and improve the energy utilization rate.

[0016] 2. On the one hand, the fixing component provided by the present invention ensures that the copper bars will not tilt or slip during the caching stage and when transferred into the annealing box, making the copper bars arranged neatly. On the other hand, one of the core structures of the fixing component is a safety component. When the caching component is in the state of caching and loading materials, the safety component based on the mechanical structure prevents the driving component from being accidentally started, thereby avoiding driving the caching component to rotate. By means of mechanical linkage, the accidental start of the driving component is avoided, ensuring operation safety. Without an additional electronic control system, only relying on mechanical principles to achieve safety protection can prevent the copper bars from falling or equipment damage caused by misoperation, improving the stability and safety of the entire annealing process. Moreover, an automatic limit component is additionally provided on the side of the fixing component of the present invention, and the automatic limit component can make the automatic clamping rod in the fixing component quickly approach the auxiliary clamping rod, so as to quickly and batch fix a plurality of rolled copper bars.

[0017] 3. The present invention is provided with a gas supply component on the top of the annealing box. When annealing is carried out inside the annealing box, the gas supply component can inject protective gas into the annealing box to reduce the oxidation of the rolled copper bars during annealing. And there is a linkage between the gas supply component and the caching component. Only when the caching component completely closes the side of the annealing box can the gas supply component inject protective gas into the annealing box. First of all, in terms of safety, if the caching component is not completely closed, gas supply may cause leakage of the protective gas, which not only wastes gas but also may affect the safety of the working environment. For example, if an inert gas is used, leakage may cause lack of oxygen. Therefore, the linkage mechanism can ensure that gas is supplied only when it is closed to prevent leakage. If the gas supply is turned on when the box is not closed, the protective gas will be wasted, increasing costs. The linkage mechanism ensures that gas is supplied only when needed, saving gas usage and reducing operating costs.

[0018] 4. The present invention is provided with a transverse movement component on the rear side of the annealing box. The transverse movement component is linked with the driving component to control the transverse movement of the heating tube. When the driving component does not act, the transverse movement component will make the heating tube as close as possible to a plurality of rolled copper bars inside the annealing box to improve the heating efficiency. The heating tube is closer to the plurality of rolled copper bars, and heat conduction is faster, saving energy. When the driving component acts, it will be linked with the transverse movement component to drive the heating tube to retreat to a certain position to avoid affecting the rotation of the caching component.

[0043] A top arc cover 1 is fixedly provided at the top of the annealing box 5. A gas supply pipe 16 is fixedly provided on the side of the top arc cover 1. The other end of the gas supply pipe 16 is fixedly connected to a docking cylinder 17. The central pipe 27 is inserted into the docking cylinder 17. The gas supply pipe 16 needs to be externally connected to a protective gas supply system, such as a mixed supply device of nitrogen and hydrogen, to avoid both ends of the central pipe 27 being provided with alternating current holes 271. A partition plate 272 is fixedly provided at the middle position of the inner cavity of the central pipe 27. The side of the carrier plate 29 is provided with air outlet holes 291. The alternating current hole 271 at the bottom of the central pipe 27 is communicated with the air outlet holes 291. The setting of the partition plate 272 divides the inner cavity of the central pipe 27 into two independent chambers.

[0044] The transverse movement components include a common plate 6, a central iron disc 9, and a central electromagnet 11. A central electromagnet 11 is fixedly provided at the central position on the side of the rear sealing plate 4. The output end of the central electromagnet 11 extends into the annealing box 5. The side of the common plate 6 is equidistantly provided with heating tubes 61. The common plate 6 is fixedly provided with auxiliary columns 10 on the side opposite to the heating tubes 61. The auxiliary columns 10 are movably inserted into the side of the rear sealing plate 4. One end of the outer wall of the auxiliary column 10 is fixedly connected to one end of a spring 12 away from the common plate 6, and the other end of the spring 12 away from the common plate 6 is fixedly connected to the side of the rear sealing plate 4.

[0045] The common plate 6 is fixedly provided with a central iron disc 9 at the central position on the side opposite to the heating tubes 61. The circuit of the central electromagnet 11 is connected in parallel with the circuit of the flipping cylinder 26. The common plate 6 is made of a heat-insulating material. A one-way valve 8 is fixedly provided at the top of the annealing box 5. A controller 7 is fixedly provided at the edge position on the side of the annealing box 5. The controller 7 is a PLC controller device in the prior art. The one-way gas flow direction of the one-way valve 8 is from the inner cavity of the annealing box 5 to the outside of the annealing box 5. The one-way valve 8 needs to be externally connected to an exhaust gas treatment system. The one-way valve 8 is used for exhausting the waste gas of the annealing box 5.

[0046] The specific implementation steps and principles of the present invention are as follows: When the annealing box 5 is in the standby state, the heating tube 61 on the common board 6 is at the closest distance to the carrier plate 29. The movable clamping rod 31 on the outer side of the carrier plate 29 is at the closest distance from the auxiliary clamping rod 30. The bottom limit block 15 crosses the top limit block 13. The rolled copper strip inside the annealing box 5 on the carrier plate 29 is heated and annealed by the heating tube 61. When it is necessary to cache the rolled copper strip on the outer side of the carrier plate 29, the bottom limit block 15 is pressed down by the release plate 36, and then the movable clamping rod 31 is pulled away from the auxiliary clamping rod 30. At this time, the active magnet 35 at the top of the auxiliary rod 33 moves below the driven magnet 23, repelling the folded rod 22 to move vertically upward, driving the active tooth bar 19 to disengage from the plane where the driven gear 18 is located. At this time, even if the flipping cylinder 26 extends, it is impossible to drive the carrier plate 29 at the bottom of the driven gear 18 to rotate through the active tooth bar 19. At this time, the carrier plate 29 closes the side of the annealing box 5, and the AC hole 271 at the top of the central tube 27 is communicated with the air supply pipe 16.

[0047] When the worker adds enough rolled copper strips to the outer side of the carrier plate 29, the movable clamping rod 31 is manually pushed close to the auxiliary clamping rod 30. At this time, the active magnet 35 at the top of the auxiliary rod 33 moves away from below the driven magnet 23, and the folded rod 22 falls back due to its own weight, driving the active tooth bar 19 to fall back to the plane where the driven gear 18 is located. Due to the existence of the top inclined surface 151 and the bottom inclined surface 14, the bottom limit block 15 will first move downward to compress the release spring 37. After waiting for the bottom limit block 15 to cross the top limit block 13, the release spring 37 resets and drives the bottom limit block 15 to insert into the side of the top limit block 13.

[0048] When the flipping cylinder 26 is started, the central electromagnet 11 will also be started synchronously. By attracting the central iron disk 9, it quickly drives the heating tube 61 on the side of the common board 6 close to the rear sealing plate 4. The flipping cylinder 26 can drive the integral structure of the closing disk 28 and the carrier plate 29 to rotate 180 degrees to anneal the just-cached material. After waiting for a period of time, the central electromagnet 11 is powered off, and under the reset of the away spring 12, the heating tube 61 returns to its initial position.

[0049] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
