Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of copper conductor wires, specifically relating to an annealing furnace for copper conductors of ultra-high voltage cross-linked power cables. Background Technology
[0002] Copper conductor wire, as the name suggests, is a conductive wire made of copper. Based on its different physical properties and applications, copper conductor wire can be divided into various types, such as hard copper wire, soft copper wire, semi-hard copper wire, tinned copper wire, oxygen-free copper wire, enameled wire, copper foil wire, copper-clad steel, and alloy copper, etc. Copper conductor wire is widely used in many fields such as power, communications, construction, transportation, and home appliances. In power transmission, copper conductor wire is an important component of power cables, transformers, switches, connecting elements, and connectors; in the communications field, copper conductor wire is used to transmit various signals, ensuring signal transmission quality and stability; in home appliances, copper conductor wire is used for circuit connections, ensuring normal power supply and safe use of appliances.
[0003] Chinese patent CN205656909U discloses a tin-plated copper wire annealing furnace, comprising a wire guide tube for passing tin-plated copper wire and a heat-insulating tube for heat preservation. The wire guide tube has a cavity in the middle for the tin-plated copper wire to pass through. The wire guide tube includes a first heating layer near the cavity, a second heating layer near the heat-insulating tube, and a magnesium oxide layer disposed between the first and second heating layers. The tin-plated copper wire annealing furnace proposed in this invention directly uses the wire guide tube as the heating element, significantly improving heat transfer efficiency. It simplifies the multiple radiation and conduction processes of the heat transfer structure into a single radiation and conduction process, eliminating shielding losses and additional heat losses. It employs concentric normal radiation, greatly improving heat transfer efficiency and minimizing energy loss. Furthermore, the temperature at all points within the tube is uniform, ensuring stable and uniform physical and mechanical properties of the tin-plated copper wire passing through the annealing furnace at a constant speed. This makes the wire less prone to oxidation, prevents the fine wire from sticking together, and results in high-quality annealing. Compared to the aforementioned documents, while the aforementioned documents can directly use the conduit as a heating element, significantly improving heat transfer efficiency, simplifying the multiple radiation and conduction processes of the heat transfer structure into a single radiation and conduction process, eliminating shielding losses and additional heat losses, and employing center-to-center normal radiation, resulting in significantly improved heat transfer efficiency, low energy consumption loss, and uniform temperature at all points within the conduit, ensuring stable and uniform physical and mechanical properties of the tin-plated copper wire passing through the annealing furnace at a constant speed, making it less prone to oxidation, preventing the fine wires from sticking together, and ensuring good annealing quality, the copper wire needs to be burned during the annealing process. Since copper wire contains some sulfur, the combustion of sulfur produces harmful fumes. After annealing, some harmful fumes accumulate inside the annealing furnace. When the furnace lid is opened, the harmful fumes diffuse from the inside of the annealing furnace to the outside, indirectly reducing the environmental quality of the copper wire production site. Therefore, an annealing furnace for copper conductors of ultra-high voltage cross-linked power cables is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an annealing furnace for copper conductors of ultra-high voltage cross-linked power cables, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An annealing furnace for copper conductors of ultra-high voltage cross-linked power cables includes an annealing furnace and further includes: An exhaust purification mechanism is used to purify and discharge the gas generated inside the annealing furnace. The exhaust purification mechanism is located above the annealing furnace and includes a suction fan installed on the top of the annealing furnace. An exhaust pipe is connected to the top of the suction fan. Multiple fixed plates are fixedly connected inside the exhaust pipe. A rotating shaft is rotatably connected to the fixed plates. A drive fan is fixedly connected to the outer wall of the rotating shaft. A rotating magnetic block is fixedly connected to the end of the drive fan. Multiple storage tanks are fixedly connected to the top of the outer wall of the exhaust pipe. The bottom of the storage tank and the exhaust pipe are both provided with outlets, and two outlets are correspondingly connected. Tension springs are fixedly connected to the bottom of the inner wall of the storage tank on both sides of the outlet. A sliding rod is fixedly connected to one end of the tension spring. A baffle is fixedly connected to one end of the sliding rod. An exhaust mesh plate is fixedly connected to the end of the exhaust pipe away from the suction fan. A feeding mechanism is used to add the copper wire to be annealed into the interior of the annealing furnace. The feeding mechanism is located on the annealing furnace and includes a sliding cavity opened on the annealing furnace. A telescopic spring is fixedly connected inside the sliding cavity. A telescopic plate is fixedly connected to the bottom end of the telescopic spring and slides to the outside of the sliding cavity. A mounting baffle is fixedly connected to the bottom of the telescopic plate, and an arc-shaped block is fixedly connected to the mounting baffle.
[0006] Preferably, the outer diameter of the sliding rod is smaller than the inner diameter of the outlet, and the outer wall of the bonding baffle is slidably bonded to the inner wall of the outlet.
[0007] Preferably, the bonding baffle is a magnetic block, and the bonding baffle and the rotating magnetic block are arranged with opposite poles attracting each other.
[0008] Preferably, the annealing furnace has an air outlet at the top, and the suction fan is connected to the interior of the annealing furnace through the air outlet.
[0009] Preferably, the top of the annealing furnace is provided with a feeding port, and the mounting baffle is correspondingly fitted to the feeding port.
[0010] Preferably, the arc-shaped block extends into the interior of the feed inlet.
[0011] Compared with the prior art, the beneficial effects of this utility model are: Through the exhaust purification mechanism, as gas is discharged through the exhaust pipe, the impact of the gas drives the fan to rotate. This rotation of the fan, in turn, causes the rotating magnetic block at its end to rotate. When the magnetic block reaches the position of the contact baffle, the attraction between the opposite poles causes the contact baffle to slide outwards from the outlet, opening the outlet and allowing the purifying agent inside the storage tank to be discharged through the outlet. This allows the purifying agent to mix with the gas. Furthermore, the exhaust mesh plate reduces the gas discharge speed, ensuring thorough contact and mixing between the gas and the purifying agent, thus improving the purification effect of the discharged gas. This prevents the accumulation of harmful fumes inside the annealing furnace after annealing, thereby improving the environmental quality of the copper wire production site.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Example 1 like Figure 1-4As shown, an annealing furnace for copper conductors of ultra-high voltage cross-linked power cables includes an annealing furnace 1 and a furnace cover 4 installed on the top of the outer wall of the annealing furnace 1. It also includes an exhaust purification mechanism for purifying and discharging the gas generated inside the annealing furnace 1. The exhaust purification mechanism is located above the annealing furnace 1 and includes a suction fan 2 installed on the top of the furnace cover 4. An exhaust pipe 201 is connected to the top of the suction fan 2. Multiple fixing plates 202 are fixedly connected inside the exhaust pipe 201. A rotating shaft 2011 is rotatably connected to the fixing plate 202. A drive fan 203 is fixedly connected to the outer wall of the rotating shaft 2011. A rotating magnetic block 204 is fixedly connected to the end of the drive fan 203. Multiple storage tanks 205 are fixedly connected to the top of the outer wall of the exhaust pipe 201. Both the bottom of the storage tank 205 and the exhaust pipe 201 are provided with outlets 206, and the two outlets 206 are connected to each other. Tension springs 207 are fixedly connected to the bottom of the inner wall of the storage tank 205 on both sides of the outlets 206. A sliding rod 208 is fixedly connected to one end of the tension spring 207. A fitting baffle 209 is fixedly connected to one end of the sliding rod 208. An exhaust mesh plate 2010 is fixedly connected to the end of the exhaust pipe 201 away from the suction fan 2. The present invention is further described in detail as follows: the outer diameter of the sliding rod 208 is smaller than the inner diameter of the outlet 206; the outer side wall of the contact baffle 209 and the inner side wall of the outlet 206 are slidably contacted; the contact baffle 209 is a magnetic block; the contact baffle 209 and the rotating magnetic block 204 are corresponding opposite poles attracting each other; the top of the furnace cover 4 is provided with an air outlet; the suction fan 2 is connected to the interior of the annealing furnace 1 through the air outlet. As can be seen from the above, the annealing furnace 1 is used to anneal and heat copper wires. This is existing technology, and its working principle will not be described in detail. When annealing furnace 1 anneals copper wires, the suction fan 2 is turned on to make it work, so that the gas generated inside annealing furnace 1 is drawn into the suction fan 2 through the air outlet and discharged through the exhaust pipe 201. When the gas is discharged through the exhaust pipe 201, the impact of the gas blows the drive fan 203 to rotate. When the drive fan 203 rotates, it drives the rotating magnetic block 204 at its end to rotate. When the rotating magnetic block 204 rotates to the position of the contact baffle 209, the contact baffle 209 slides towards the outside of the outlet 206 due to the attraction between the opposite poles of the two, opening the outlet 206 and allowing the purifying agent inside the storage tank 205 to be discharged through the outlet 206. This allows the purifying agent to mix with the gas. In addition, the gas outlet mesh plate 2010 reduces the gas discharge speed, allowing the gas and purifying agent to fully contact and mix, improving the purification effect of the discharged gas. This prevents harmful fumes from accumulating inside the annealing furnace 1 after annealing, thereby improving the environmental quality of the copper wire production site.
[0016] Example 2 like Figure 1-4 As shown, a feeding mechanism is added based on the above embodiment 1 to add the copper wire to be annealed into the interior of the annealing furnace 1. The feeding mechanism is located on the furnace cover 4 and includes a sliding cavity 3 opened on the furnace cover 4. A telescopic spring 301 is fixedly connected inside the sliding cavity 3. A telescopic plate 302 is fixedly connected to the bottom end of the telescopic spring 301, and the telescopic plate 302 slides to the outside of the sliding cavity 3. A mounting baffle 303 is fixedly connected to the bottom of the telescopic plate 302, and an arc-shaped block 304 is fixedly connected to the mounting baffle 303. The present invention is further described in detail as follows: the top of the furnace cover 4 is provided with a feeding port, the mounting baffle 303 is correspondingly fitted to the feeding port, and the arc-shaped block 304 extends into the interior of the feeding port; As can be seen from the above, when the workers are feeding copper wire materials, they add the materials into the annealing furnace 1 through the feeding port. Under the action of gravity, the mounting baffle 303 and the arc block 304 can be pressed down, causing the mounting baffle 303 to separate from the feeding port, so that the materials can be added into the annealing furnace 1. With this structure, after the materials are added, the mounting baffle 303 can automatically close and block the feeding port according to the action of the telescopic spring 301, preventing harmful gases from being discharged through the feeding port.
