Description

Technical Field

[0001] This invention relates to the field of copper busbar processing technology, specifically to a waste heat recovery and utilization device in the copper busbar production process. Background Technology

[0002] In the copper busbar production process, smelting is a key step, which involves high-temperature heating to melt the copper raw materials. During this process, the copper busbar generates a large amount of waste heat. If this waste heat is not recovered and utilized and is directly discharged into the environment, it will not only waste energy but also cause the internal temperature of the factory to rise, thereby affecting the working environment and the operating efficiency of equipment. Therefore, waste heat recovery and utilization equipment in the copper busbar production process has emerged.

[0003] There are still some problems with existing waste heat recovery and utilization equipment in the copper busbar production process. During the copper busbar smelting process, some impurities are inevitably generated in the smelted copper. These impurities mainly come from trace elements contained in the copper raw materials themselves, as well as compounds formed by the interaction with furnace charge and refractory materials during the smelting process. When the vacuum pump draws the waste gas generated during the smelting process into the device, these impurities are drawn in along with the waste gas and adhere to the external heat exchange equipment or other key components inside the device. These adhered impurities gradually form a layer of thermal resistance, hindering the transfer of heat, which makes it impossible to effectively recover and reuse waste heat, resulting in a decrease in energy utilization efficiency.

[0004] The presence of thermal resistance leads to the need for more energy to maintain the same production rate during the smelting process, thereby increasing production costs. Secondly, the reduction in heat exchange efficiency affects the stability and controllability of the smelting process, increasing operational difficulty and product quality instability. Furthermore, the accumulation of thermal resistance over long-term operation also leads to equipment overheating, accelerated wear, and shortened equipment lifespan. Existing equipment relies on manual cleaning of its interior, which is not only cumbersome but also poses a significant risk of accidental injury to operators, thus compromising their safety.

[0005] Meanwhile, during the copper busbar production process, the internal temperature of the waste gas entering the waste heat recovery device will not remain constant, which will affect the heat exchange rate of the heat exchange device to the waste gas. First, the difference in raw material composition will lead to differences in the heat generated during the smelting process and the temperature of the waste gas. Furthermore, the different melting points and thermal conductivity of different metal elements in the raw materials will also affect the heat distribution and the temperature of the waste gas during the smelting process. Second, under high temperature conditions, the waste gas will suffer heat loss or dilution during transmission, resulting in a decrease in the temperature of the waste gas.

[0006] When the temperature of the exhaust gas decreases, the heat transfer efficiency also decreases. This is because the heat transfer efficiency is directly proportional to the temperature difference; the greater the temperature difference, the higher the heat transfer efficiency. When the exhaust gas temperature is low, the temperature difference between the exhaust gas and the recovery medium decreases, the heat transfer power weakens, and the heat recovery efficiency decreases. This not only affects the full utilization of waste heat but also increases the operating and maintenance costs of the equipment.

[0007] Therefore, a waste heat recovery and utilization device for the copper busbar production process is proposed. Summary of the Invention

[0008] The purpose of this invention is to provide a waste heat recovery and utilization device in the copper busbar production process to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a waste heat recovery and utilization device in the copper busbar production process, comprising a vacuum pump, an input pipe fixedly connected to the outer surface of the vacuum pump, an output pipe fixedly connected to the outer surface of the vacuum pump on the side away from the input pipe, a blocking component provided on the outside of the input pipe to prevent impurities generated during copper busbar smelting from being sucked into the vacuum pump, and an adaptive waste gas heat exchange efficiency adjustment component provided inside the input pipe.

[0010] Preferably, the blocking assembly includes a blocking housing, which is fixedly connected to the end of the input pipe away from the vacuum pump. A centrifugal shaft is eccentrically rotatably connected inside the blocking housing. Rotating components are fixedly connected to the surface of the centrifugal shaft in an annular arrangement at equal intervals. Flow blades are rotatably connected to the surface of each rotating component.

[0011] Preferably, the adjusting component includes a fixing plate, which is fixedly connected to the inner wall of the input pipe. A cylinder is fixedly connected to the surface of the fixing plate. A sliding groove is formed on the surface of the telescopic shaft of the cylinder. A sliding rod is slidably connected inside the sliding groove. A valve core is fixedly connected to the surface of the telescopic shaft of the cylinder.

[0012] Preferably, the blocking assembly further includes a circular groove, which is symmetrically formed on the inner wall of the blocking housing. The ends of the flow blades away from the rotating part are slidably connected to the inside of the circular groove. An air inlet is eccentrically formed on the side surface of the blocking housing away from the input pipe, and an air outlet communicating with the input pipe is formed on the side surface of the blocking housing near the input pipe.

[0013] Preferably, the adjustment assembly further includes a push-pull switch, which is fixedly installed on the inner wall of the input tube near the sliding rod. An input shaft is rotatably connected to the surface of the fixed plate away from the cylinder. A mating bevel gear is fixedly connected to the surface of the input shaft. A drive bevel gear connecting rod is rotatably connected through the inner wall of the input tube. A crankshaft is fixedly connected to the end of the input shaft away from the fixed plate. A rotating rod is rotatably connected to the inner wall of the input tube. A guide plate is fixedly connected to the surface of the rotating rod. A connector is rotatably connected to the end of the crankshaft away from the input shaft. The end of the connector away from the crankshaft is rotatably connected to the outer surface of the rotating rod.

[0014] Preferably, the centrifugal shaft is drivenly mounted on a first external motor, and the first external motor and the vacuum pump are electrically controlled to start and stop by an external controller.

[0015] Preferably, the drive bevel gear connecting rod meshes with the mating bevel gear, and the drive bevel gear connecting rod is driven and mounted on a second external motor, which is electrically controlled to start and stop by a push-pull switch.

[0016] Preferably, the cylinder contains nitrogen gas, and the shape of the valve core is adapted to the shape of the inner wall of the input pipe.

[0017] Preferably, both the blocking component and the adjusting component are made of tungsten alloy.

[0018] Preferably, the outer surface of the input pipe is connected to a heat exchange device, and the heat exchange device has a built-in heat treatment device.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The centrifugal force generated by the eccentrically set centrifugal shaft driving the flow blades, along with the design of the air inlet and outlet being off-center, effectively prevents impurities generated during the smelting process from entering key components such as external heat exchange equipment. This not only improves heat exchange efficiency but also enhances the stability and controllability of the smelting process, reduces operational difficulty and product quality instability, while also reducing equipment overheating and wear, extending equipment lifespan. Furthermore, the reduced need for manual cleaning provides more effective protection for operator safety, thereby improving energy utilization efficiency in copper busbar production and reducing production costs.

[0021] 2. The temperature change is sensed by the thermal expansion and contraction of nitrogen in the cylinder, which drives the valve core to move. When the exhaust gas temperature drops, the push-pull switch is triggered, causing the exhaust gas to form turbulence under the swing, thereby improving the heat transfer efficiency. The thermal expansion and contraction of nitrogen in the cylinder can accurately sense the change in exhaust gas temperature, thereby adjusting the movement state of the valve core in time. This not only improves the response speed of heat exchange, but also helps to maintain a stable heat transfer efficiency.

[0022] 3. Secondly, the movement of the valve core can be adaptively adjusted according to the changes in the exhaust gas temperature, ensuring the continuity and stability of the heat recovery process. When the exhaust gas temperature decreases, the guide plate will swing, which will cause the exhaust gas to form turbulence. The turbulent state increases the contact area and flow velocity between the exhaust gas and the recovery medium, thereby improving the heat transfer efficiency. In addition, by improving the heat transfer efficiency, the waste heat is utilized more fully, and energy waste can be reduced, thereby reducing the operating and maintenance costs of the equipment. As the stability of the heat recovery process is enhanced, the wear and failure rate of the equipment will also be reduced accordingly, further extending the service life of the equipment.

[0036] Please see Figures 1 to 8 As shown, the present invention provides an embodiment:

[0037] A waste heat recovery and utilization device in the copper busbar production process includes a vacuum pump 1, an input pipe 2 fixedly connected to the outer surface of the vacuum pump 1, a heat exchange device connected to the outer surface of the input pipe 2, a heat treatment device built into the heat exchange device, an output pipe 3 fixedly connected to the outer surface of the vacuum pump 1 away from the input pipe 2, a blocking component provided on the outside of the input pipe 2 to prevent impurities generated during the smelting of the copper busbar from being sucked into the vacuum pump 1, and an adaptive waste gas heat exchange efficiency adjustment component provided inside the input pipe 2.

[0038] The blocking assembly includes a blocking housing 41, which is fixedly connected to the end of the input pipe 2 away from the vacuum pump 1. A centrifugal shaft 42 is eccentrically rotatably connected inside the blocking housing 41. The centrifugal shaft 42 is driven and mounted on a first external motor.

Rotating parts 43 are fixedly connected in a ring-shaped equidistant arrangement on the surface of the centrifugal shaft 42.

[0039] The adjustment assembly includes a fixing plate 51, which is fixedly connected to the inner wall of the input pipe 2. A cylinder 52 is fixedly connected to the surface of the fixing plate 51.

The end of the flow blade 44 away from the rotating part 43 is slidably connected to the inside of the circular groove 45.

[0041] The adjustment assembly also includes a push-pull switch 56, which is fixedly installed on the inner wall of the input pipe 2 near the sliding rod 54. An input shaft 57 is rotatably connected to the surface of the fixed plate 51 away from the cylinder 52. A mating bevel gear 58 is fixedly connected to the surface of the input shaft 57. A drive bevel gear connecting rod 59 is rotatably connected through the inner wall of the input pipe 2. The drive bevel gear connecting rod 59 meshes with the mating bevel gear 58. The drive bevel gear connecting rod 59 is driven and mounted on a second external motor. The second external motor is electrically controlled to start and stop by the push-pull switch 56. A crankshaft 510 is fixedly connected to the end of the input shaft 57 away from the fixed plate 51. A rotating rod 511 is rotatably connected to the inner wall of the input pipe 2. A guide plate 512 is fixedly connected to the surface of the rotating rod 511. A connector 513 is rotatably connected to the end of the crankshaft 510 away from the input shaft 57. The end of the connector 513 away from the crankshaft 510 is rotatably connected to the outer surface of the rotating rod 511.

[0042] The working principle of the present invention, based on the above implementation, is as follows:

[0043] The initial state is as follows: the sliding rod 54 is located at the bottom of the sliding groove 53, the cylinder 52 is not in the extended state, and the push-pull switch 56 is not triggered.

[0044] The following are the specific steps for operation:

[0045] like Figure 1 and Figure 2 As shown, the operator manipulates the external controller and causes the external controller to electrically control the vacuum pump 1 and the first external motor to start.

[0046] Among these measures, measures are taken to prevent impurities generated during the copper smelting process from entering the inside of the input pipe 2:

[0047] As vacuum pump 1 is started, a vacuum is gradually formed inside vacuum pump 1. At this time, the gas pressure inside vacuum pump 1 is lower than the external atmospheric pressure. Under the action of atmospheric pressure, the waste gas in the copper busbar smelting process will be forced into vacuum pump 1 through vacuum pump 1 and input pipe 2.

[0048] like Figure 3 and Figure 4As shown, at the same time, the first external motor starts, and the output shaft of the first external motor rotates to drive the centrifugal shaft 42 to rotate synchronously. The centrifugal shaft 42 then drives the flow blades 44 to rotate synchronously through the rotating parts 43 on its surface. Under the restriction of the circular groove 45, the flow blades 44 will follow the centrifugal shaft 42 to make an eccentric rotation with the blocking housing 41 as the center.

[0049] According to Bernoulli's principle in fluid mechanics, in an incompressible fluid, the pressure is low where the flow velocity is high and high where the flow velocity is low. Since the exhaust gas enters the input pipe 2 through vacuum pump 1 via inlet 46 and exits through outlet 47, and because outlet 47 and inlet 46 are offset from the center of the obstruction housing 41, the exhaust gas does not move in a straight line along the center of the obstruction housing 41, but rather along an inclined path. Because the flow path of the exhaust gas through the obstruction housing 41 is inclined and constantly changes with the rotation of the flow vanes 44, the flow velocity of the exhaust gas changes as it passes through the obstruction housing 41. This change in velocity leads to a change in pressure, thus forming a dynamic pressure field. This pressure field helps guide the exhaust gas to pass more smoothly through the obstruction housing 41.

[0050] Meanwhile, the rotation of the flow vane 44 inside the circular groove 45 plays a crucial role. The rotating flow vane 44 not only forms a dynamic barrier, but also effectively prevents impurities from entering the interior of the barrier housing 41 through the centrifugal force generated by its rotation. When the flow vane 44 rotates inside the circular groove 45, the flow vane 44 will continuously change its position relative to the centrifugal axis 42. This rotation forms a dynamic barrier, so that when impurities try to enter the barrier housing 41, they will encounter the constantly changing position of the flow vane 44, thereby increasing the difficulty for impurities to enter. Moreover, since the mass of impurities is greater than the mass of exhaust gas, when the flow vane 44 rotates, the impurities are more easily affected by centrifugal force. Centrifugal force is the outward force that an object experiences when rotating. In this way, the centrifugal force will push the impurities away from the side away from the air inlet 46, and the centrifugal force will further enhance the effect of the barrier assembly in preventing impurities from entering the interior of the input pipe 2.

[0051] Furthermore, as described in the above steps, the inclined movement path facilitates the entry of exhaust gas. When the exhaust gas flows, impurities in the exhaust gas are more easily affected by gravity and settle downwards. The inclined path causes impurities to be subjected to the combined effects of gravity and centrifugal force when passing through the inlet 46. Gravity pulls the impurities towards the bottom of the inlet 46, while centrifugal force pushes them towards the periphery of the inlet 46. Under the dual action of gravity and centrifugal force, impurities are more difficult to enter the interior of the blocking housing 41. Thus, under the combined action of the eccentric design, the inclined gas flow trajectory, and centrifugal force, impurities in the exhaust gas are more difficult to enter the interior of the input pipe 2 through the inlet 46. The centrifugal force generated by the centrifugal shaft 42 driving the flow blades 44, along with the off-center design of the air inlet 46 and outlet 47, effectively prevents impurities generated during the smelting process from entering key components such as external heat exchange equipment. This not only improves heat exchange efficiency but also enhances the stability and controllability of the smelting process, reduces operational difficulty and product quality instability, while also reducing equipment overheating and wear, extending equipment lifespan. Furthermore, the reduced need for manual cleaning enhances operator safety, thereby improving energy efficiency in copper busbar production and reducing production costs.

[0052] Among them, adaptive improvement of heat exchange efficiency:

[0053] like Figures 3 to 5 As shown, when the exhaust gas enters the input pipe 2 through the outlet 47, the high temperature of the exhaust gas causes the nitrogen inside the cylinder 52 on the surface of the fixed plate 51 to expand due to heat. The expanding cylinder 52 pushes the telescopic shaft of the cylinder 52 towards the direction of the vacuum pump 1. The telescopic shaft of the cylinder 52 then pushes the valve core 55 to move synchronously. During this process, the sliding rod 54 will come into contact with the push-pull switch 56. In order to overcome the obstruction of the push-pull switch 56 and to follow the movement of the telescopic shaft of the cylinder 52, the sliding rod 54 will slide upward along the trajectory of the push-pull switch 56 inside the sliding groove 53. When the sliding rod 54 completely passes the push-pull switch 56, it will slide to the bottom of the sliding groove 53 under its own gravity. When the exhaust gas passes through the input pipe 2, it will be heat-exchanged by the external heat exchange device on the surface of the input pipe 2. The heat exchange device will then transfer the absorbed heat to the external heat treatment device for further processing.

[0054] When influenced by external factors, the temperature of the exhaust gas drawn into the vacuum pump 1 decreases. At this time, the nitrogen inside the cylinder 52 will contract due to the temperature change of the exhaust gas. Consequently, the telescopic shaft of the cylinder 52 will move away from the vacuum pump 1. The telescopic shaft of the cylinder 52 will then drive the valve core 55 to move synchronously. Due to the movement of the valve core 55, the gap between the valve core 55 and the inner wall of the input pipe 2 increases. As a result, the flow rate of the exhaust gas increases when it passes through the valve core 55. The increase in flow rate can increase the contact speed and contact area between the exhaust gas and the surface of the external heat exchange equipment, thereby accelerating the rate at which heat is transferred from the exhaust gas to the external heat exchange equipment. This helps to compensate for the decrease in heat transfer efficiency caused by the decrease in exhaust gas temperature.

[0055] like Figure 7 and Figure 8 As shown, simultaneously, under the movement of the telescopic shaft of cylinder 52, sliding rod 54 again comes into contact with push-pull switch 56. At this time, due to the shape limitation of push-pull switch 56, sliding rod 54 cannot follow the trajectory of push-pull switch 56 to move along the telescopic shaft of cylinder 52. Therefore, in order to overcome the obstruction of push-pull switch 56, sliding rod 54 will push push-pull switch 56 away from vacuum pump 1 during the process of following the telescopic shaft of cylinder 52. At this time, push-pull switch 56 is opened, and push-pull switch 56 will electrically control the second external motor to start.

[0056] like Figure 1 and Figure 6 As shown, at this time, the second external motor starts, and the output shaft of the second external motor rotates, which drives the bevel gear connecting rod 59 to rotate synchronously. The drive bevel gear connecting rod 59 then drives the meshing bevel gear 58 to rotate. In turn, the meshing bevel gear 58 drives the crankshaft 510 to rotate synchronously through the input shaft 57. When the crankshaft 510 rotates, it will pull the connecting piece 513 to generate a synchronous rotation tendency. In order to adapt to the rotation of the crankshaft 510, the connecting piece 513 will drive the rotating rod 511 to swing back and forth. The swinging of the rotating rod 511 will drive the guide plate 512 to swing synchronously.

[0057] During the oscillation of the guide plate 512, the exhaust gas continues to move towards the vacuum pump 1 along the trajectory of the guide plate 512. During this process, the exhaust gas is forced to change direction and velocity. With these continuous changes in direction and velocity, the exhaust gas in the input pipe 2 is in an unstable flow state, i.e., turbulence. In turbulence, the contact area and contact time between the exhaust gas and the surface of the external heat exchanger increase. This is because the exhaust gas in turbulence constantly undergoes small-scale vortices and mixing, allowing the heat in the exhaust gas to be transferred more fully to the surface of the external heat exchanger. Simultaneously, the more intense movement of fluid molecules in turbulence helps to accelerate the rate at which heat is transferred from the exhaust gas to the external heat exchanger. Furthermore, the exhaust gas in turbulence can be better distributed and mixed inside the input pipe 2, which helps to evenly transfer heat to the surface of the external heat exchanger, avoiding localized overheating or undercooling, thereby improving heat exchange efficiency. Thus, the decrease in thermal efficiency caused by the decrease in exhaust gas temperature is compensated for by the combined effect of the exhaust gas flow rate and the mixing effect of turbulence. The nitrogen gas in cylinder 52 senses temperature changes through thermal expansion and contraction, which in turn moves valve core 55. When the exhaust gas temperature decreases, push-pull switch 56 is triggered, causing the exhaust gas to swirl and form turbulence, thereby improving heat transfer efficiency. The thermal expansion and contraction of the nitrogen gas in cylinder 52 accurately senses changes in exhaust gas temperature, thus adjusting the movement of valve core 55 in a timely manner. This not only improves the response speed of heat exchange but also helps maintain stable heat transfer efficiency. Furthermore, the movement of valve core 55 can adaptively adjust according to changes in exhaust gas temperature, ensuring the continuity and stability of the heat recovery process. When the exhaust gas temperature decreases, guide plate 512 oscillates, causing the exhaust gas to swirl and form turbulence. The turbulent state increases the contact area and flow velocity between the exhaust gas and the recovery medium, thereby improving heat transfer efficiency. In addition, by improving heat transfer efficiency, waste heat is utilized more fully, while reducing energy waste and thus lowering equipment operating and maintenance costs. As the stability of the heat recovery process is enhanced, equipment wear and failure rates are also reduced, further extending the equipment's service life.
