Technical Field
[0001] This invention relates to the technical field of stainless steel wire production quenching equipment, specifically a stainless steel wire production quenching equipment with waste heat recovery function. Background Technology
[0002] Stainless steel wire quenching equipment is a core component in the deep processing of stainless steel wire. Through a heat treatment process of "high-temperature heating - rapid cooling," it alters the internal microstructure of the stainless steel wire, such as transforming austenite into martensite, thereby significantly improving its mechanical properties such as hardness, strength, and wear resistance. This lays the foundation for subsequent drawing and forming processes. The equipment must balance precise heating, efficient cooling, continuous production, and energy conservation and environmental friendliness, and is widely used in the production of high-performance wires such as spring steel wire, bearing steel wire, and stainless steel wire rope wire.
[0003] In the quenching process of stainless steel wire production, to achieve a significant improvement in the mechanical properties of the wire, it is necessary to precisely control the wire to the austenitizing critical temperature through a high-temperature heating process. However, traditional quenching equipment has a prominent energy consumption problem in this process: the equipment generally lacks an effective heat recovery design, and the oil and gas vapors volatilized after the high-temperature wire exchanges heat with the medium during quenching and cooling, which carry a large amount of sensible heat, are directly discharged into the air, resulting in serious energy waste. Summary of the Invention
[0004] To achieve the above objectives, the present invention provides the following technical solution: a stainless steel wire quenching equipment with waste heat recovery function, comprising:
[0005] A workbench is provided, with a wire feeding frame fixedly connected to one side of the workbench, a wire take-up frame fixedly connected to the side of the workbench away from the wire feeding frame, a straightening component fixedly connected to the top of the workbench, and a high-frequency induction heating furnace fixedly connected to the middle of the top of the workbench.
[0006] A cleaning component is used to clean the stainless steel wire passing through the straightening component, and the bottom of the cleaning component is fixedly connected to the top of the workbench.
[0007] A quenching component is used to quench stainless steel wire passing through a high-frequency induction heating furnace. The side of the quenching component is fixedly connected to the inside of the workbench.
[0008] The cleaning component includes a cleaning frame, the bottom of which is fixedly connected to the top of the workbench. Sliding rods are slidably connected to both sides of the inner cavity of the cleaning frame. A fixed frame is fixedly connected to the other end of each sliding rod. The side of the fixed frame is slidably connected to the inner side of the fixed frame. A cleaning roller is rotatably connected to the side of the fixed frame away from the sliding rods. A first spring is sleeved on the sliding rod. One end of the first spring is fixedly connected to the side of the fixed frame, and the other end of the first spring is fixedly connected to the inner side of the cleaning frame.
[0009] Preferably, after the wire is straightened by the straightening component, it immediately enters the cleaning frame for surface treatment. The cleaning frame is equipped with two sliding rods on the inside. Under the elastic force of the first spring, the two cleaning rollers move closer to each other synchronously, so that the cleaning rollers are in close contact with the side of the wire and generate rolling friction as the wire moves. This elastic and adaptive contact cleaning method can remove impurities such as oxide scale and oil stains attached to the surface of the wire and avoid impurity residue.
[0010] Preferably, the quenching component includes a quenching tank, the side of which is fixedly connected to the inner side of the workbench, support plates fixedly connected to both sides of the top of the quenching tank, a connecting pipe fixedly connected to the inner side of the support plates, a spray frame fixedly connected between the two support plates, one end of the connecting pipe fixedly connected to the inner side of the quenching tank, the other end of the connecting pipe fixedly connected to the spray frame, a water pump fixedly connected to the side of the connecting pipe, a connecting mechanism fixedly connected to the top of the support plates, a fan fixedly connected to the top of the connecting mechanism, and a recovery component fixedly connected to the top of the fan.
[0011] Preferably, when the wire after high-frequency induction heating enters the quenching tank, the water pump continuously delivers the quenching oil in the quenching tank to the spray rack through the connecting pipe. The spray rack evenly sprays the quenching oil onto the surface of the wire to achieve rapid cooling. During this process, the high-temperature wire and the low-temperature quenching oil undergo violent heat exchange, causing the temperature of the quenching oil to rise, and at the same time, high-temperature flue gas is generated by volatilization.
[0012] Preferably, the connecting mechanism includes a connecting plate, the bottom of which is fixedly connected to the top of a support plate, a guide frame fixedly connected to the top of the connecting plate, the middle of the top of the guide frame fixedly connected to the bottom of the fan, an air outlet slot being provided in the middle of the top of the guide frame, a guide plate fixedly connected to the bottom of the inner cavity of the guide frame, a mesh plate fixedly connected to the bottom of the guide plate, a mesh frame fixedly connected to the middle of the top of the guide plate, and filter components fixedly connected to both sides of the bottom of the inner cavity of the connecting plate.
[0013] Preferably, at the same time, the fan is turned on, and the high-temperature flue gas is first filtered by the filter components on both sides of the bottom of the connecting plate to remove large particles of impurities. Then, under the suction of the fan, it enters the inner cavity of the guide frame through the bottom mesh plate of the guide frame. The guide plate on the inner side of the guide frame guides the flue gas to flow in an orderly manner, and the top mesh frame performs secondary filtration on the flue gas to intercept fine impurities. The purified flue gas is discharged through the air outlet slot at the top of the guide frame and enters the recovery mechanism through the air inlet pipe connected to the top of the fan to complete the waste heat recovery and heat exchange. The flue gas after heat exchange and cooling is discharged after purification treatment.
[0014] Preferably, the filter assembly includes a filter housing, the side of which is fixedly connected to the inner side of a connecting plate, a filter plate slidably connected to the inner side of the filter housing, round rods fixedly connected to both sides of the top of the filter plate, the top of which is slidably connected to the bottom of the connecting plate, a third spring sleeved on the round rod, the top of which is fixedly connected to the bottom of the connecting plate, the bottom of which is fixedly connected to the top of the filter plate, a connecting shaft slidably connected to both sides of the filter plate, a scraper fixedly connected to the other end of the connecting shaft, the side of which is slidably connected to the inner side of the filter plate, and a fourth spring sleeved on the connecting shaft, one end of which is fixedly connected to the inner side of the filter plate, and the other end of which is fixedly connected to the scraper.
[0015] Preferably, the gas generated during the quenching process continuously enters the filter housing under the drive of the fan. When the gas flows upward, it pushes the filter plate to rise along the inner side of the filter housing. The filter plate moves upward synchronously through the round rod, while squeezing the third spring sleeved on the round rod. The filter plate drives the scraper to contact the inner wall of the filter housing through the connecting shafts on both sides, and completes the cleaning of the inner wall as the filter plate moves.
[0016] Preferably, by contacting the scraper with the inner wall, the dust and impurities adhering to the inner wall of the outer shell after long-term flue gas circulation are removed, avoiding the accumulation of impurities and clogging of the flow channel, ensuring smooth gas flow, and maintaining long-term efficient operation of the filter. At the same time, a fourth spring is provided between the scraper and the connecting shaft. When the contact pressure between the scraper and the impurities on the inner wall is too large, the fourth spring will contract and buffer, driving the scraper to be slightly adjusted inward towards the filter plate, avoiding scraper wear or damage to the inner wall of the outer shell caused by rigid compression.
[0017] Preferably, when the fan stops working and the gas thrust on the filter plate is less than the reset force of the third spring, the filter plate resets along the inner side of the filter housing under the action of the third spring, preparing for the next filtration cleaning cycle. The whole process realizes the automatic linkage of filtration and self-cleaning, reduces the frequency of manual maintenance, and lowers the operation and maintenance costs.
[0018] Preferably, the recovery component includes a heat exchanger, the bottom of which is fixedly connected to the top of the guide frame, an inlet pipe is fixedly connected to one side of the heat exchanger, an outlet pipe is fixedly connected to the other side of the heat exchanger, a smoke exhaust assembly is fixedly connected to the top of the heat exchanger, and the side of the heat exchanger away from the smoke exhaust assembly is fixedly connected to the top of the fan through an air inlet pipe.
[0019] Preferably, under the continuous suction of the fan, the high-temperature flue gas in the guide frame enters the heat exchanger through the air inlet pipe at the top of the fan, flows through the fin structure in the heat exchanger, and through heat conduction, the heat of the flue gas is transferred to the working fluid inside the heat pipe, thus completing the heat release.
[0020] Preferably, the heated medium enters from the heat exchanger inlet pipe and forms a counter-flow with the heat pipe condenser section, that is, the medium flows in the opposite direction to the flue gas. It absorbs the heat transferred by the heat pipe through the fins. After absorbing the heat, the medium temperature rises and is transported to each energy-consuming equipment through the outlet pipe to realize the utilization of waste heat.
[0021] Preferably, the flue gas after heat exchange and cooling is then filtered and discharged through the exhaust assembly, thus realizing the recovery of waste heat and clean discharge of the flue gas.
[0022] Preferably, the flue gas exhaust assembly includes a flue gas pipe, the side of which is fixedly connected to the inner side of the heat exchanger. A baffle is fixedly connected to the top of the flue gas pipe, and a rotating rod is rotatably connected to the bottom of the baffle. Rotating frames are fixedly connected to both sides of the rotating rod, and fixed rods are fixedly connected to both sides of the rotating frames. A cleaning brush is fixedly connected to the top of the fixed rod, and the top of the cleaning brush is fixedly connected to the bottom of the baffle. A spiral blade is fixedly connected to the bottom of the rotating rod.
[0023] This invention provides a stainless steel wire quenching equipment with waste heat recovery function. It has the following beneficial effects:
[0024] 1. This stainless steel wire quenching equipment with waste heat recovery function is equipped with a cleaning component. Through the buffering and pressing action of the spring, the cleaning roller can automatically adjust the contact force according to the slight changes in the wire diameter, ensuring that the entire surface is cleaned without dead corners, improving surface cleanliness. The thorough removal of impurities can avoid local temperature deviations caused by surface impurities blocking heat conduction during the heating stage, providing a basic guarantee for the uniformity of subsequent high-frequency induction heating, thereby reducing the fluctuation of wire performance caused by uneven heat conduction.
[0025] 2. This stainless steel wire quenching equipment with waste heat recovery function is equipped with a filter assembly. During the quenching process, the gas generated continuously enters the filter shell under the drive of the fan. When the gas flows upward, it pushes the filter plate to rise along the inner side of the filter shell. The filter plate moves upward synchronously through the round rod, and at the same time squeezes the third spring sleeved on the round rod. The filter plate drives the scraper to contact the inner wall of the filter shell through the connecting shafts on both sides, and completes the inner wall cleaning as the filter plate moves.
[0026] 3. The stainless steel wire production quenching equipment with waste heat recovery function is equipped with a recovery component. Under the continuous suction of the fan, the high-temperature flue gas in the guide frame enters the heat exchanger through the air inlet pipe at the top of the fan. It flows through the fin structure in the heat exchanger and, through heat conduction, the heat of the flue gas is transferred to the working fluid inside the heat pipe, thus completing the heat release.
[0027] 4. This stainless steel wire quenching equipment with waste heat recovery function is equipped with a smoke exhaust component. The cleaning mechanism is driven by the impact force of the smoke itself to achieve real-time cleaning of the baffle. This prevents impurities in the smoke from being intercepted by the baffle and adhering to the surface in large quantities, thus preventing the screen blockage problem, ensuring the continuous smooth flow of the smoke exhaust channel, and reducing the frequency of cleaning caused by blockage.

Detailed Implementation
[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0042] Please see Figures 1-2 This invention provides a technical solution: a stainless steel wire quenching equipment with waste heat recovery function, comprising:
[0043] Workbench 1, a wire feeding rack 2 is fixedly connected to one side of workbench 1, a wire take-up rack 7 is fixedly connected to the side of workbench 1 away from the wire feeding rack 2, a straightening component 3 is fixedly connected to the top of workbench 1, and a high-frequency induction heating furnace 5 is fixedly connected to the middle of the top of workbench 1.
[0044] Cleaning component 4 is used to clean the stainless steel wire passing through the straightening component 3. The bottom of the cleaning component 4 is fixedly connected to the top of the workbench 1.
[0045] Quenching component 6 is used to quench stainless steel wire passing through high-frequency induction heating furnace 5. The side of quenching component 6 is fixedly connected to the inner side of workbench 1.
[0046] Please see Figures 1-3 The cleaning component 4 includes a cleaning frame 41. The bottom of the cleaning frame 41 is fixedly connected to the top of the workbench 1. Sliding rods 42 are slidably connected to both sides of the inner cavity of the cleaning frame 41. A fixed frame 43 is fixedly connected to the other end of the sliding rods 42. The side of the fixed frame 43 is slidably connected to the inner side of the fixed frame 43. A cleaning roller 44 is rotatably connected to the side of the fixed frame 43 away from the sliding rods 42. A first spring 45 is sleeved on the sliding rods 42. One end of the first spring 45 is fixedly connected to the side of the fixed frame 43, and the other end of the first spring 45 is fixedly connected to the inner side of the cleaning frame 41.
[0047] After the wire is straightened by the straightening component 3, it immediately enters the cleaning frame 41 for surface treatment. The cleaning frame 41 is equipped with two sliding rods 42 on the inner side. Under the elastic force of the first spring 45, the two cleaning rollers 44 move closer to each other synchronously, so that the cleaning rollers 44 are in close contact with the side of the wire and generate rolling friction as the wire moves. This elastic adaptive contact cleaning method can remove impurities such as oxide scale and oil stains attached to the surface of the wire and avoid impurity residue.
[0048] Please see Figures 1-6 The present invention provides a technical solution: the quenching component 6 includes a quenching pool 61, the side of the quenching pool 61 is fixedly connected to the inner side of the workbench 1, the top of the quenching pool 61 is fixedly connected to both sides of the top, the inner side of the support plate 65 is fixedly connected to a connecting pipe 66, the two support plates 65 are fixedly connected to a spray rack 67, one end of the connecting pipe 66 is fixedly connected to the inner side of the quenching pool 61, the other end of the connecting pipe 66 is fixedly connected to the spray rack 67, the side of the connecting pipe 66 is fixedly connected to a water pump 62, the top of the support plate 65 is fixedly connected to a connecting mechanism 63, the top of the connecting mechanism 63 is fixedly connected to a fan 68, and the top of the fan 68 is fixedly connected to a recovery component 64;
[0049] When the wire after high-frequency induction heating enters the quenching tank 61, the water pump 62 continuously delivers the quenching oil in the quenching tank 61 to the spray rack 67 through the connecting pipe 66. The spray rack 67 sprays the quenching oil evenly onto the surface of the wire to achieve rapid cooling. During this process, the high-temperature wire and the low-temperature quenching oil undergo violent heat exchange, causing the temperature of the quenching oil to rise and at the same time, it volatilizes to generate high-temperature flue gas.
[0050] The high-temperature flue gas is drawn by the fan 68 and filtered through the connecting mechanism 63 before entering the recovery component 64 for waste heat recovery. After the flue gas is cooled by heat exchange, it is then purified before being discharged.
[0051] Please see Figures 1-7 The connecting mechanism 63 includes a connecting plate 631, the bottom of which is fixedly connected to the top of the support plate 65. A guide frame 632 is fixedly connected to the top of the connecting plate 631. The middle part of the top of the guide frame 632 is fixedly connected to the bottom of the fan 68. An air outlet slot is provided in the middle part of the top of the guide frame 632. A guide plate 634 is fixedly connected to the bottom of the inner cavity of the guide frame 632. A mesh plate 633 is fixedly connected to the bottom of the guide plate 634. A mesh frame 635 is fixedly connected to the middle part of the top of the guide plate 634. Filter components 636 are fixedly connected to both sides of the bottom of the inner cavity of the connecting plate 631.
[0052] At the same time, the fan 68 is turned on. The high-temperature flue gas first undergoes preliminary filtration through the filter components 636 on both sides of the bottom of the connecting plate 631 to remove large particulate impurities. Then, under the suction of the fan 68, it enters the inner cavity of the guide frame 632 through the bottom mesh plate 633. The guide plate 634 on the inner side of the guide frame 632 guides the flue gas to flow in an orderly manner. The top mesh frame 635 performs secondary filtration on the flue gas to intercept fine impurities. The purified flue gas is discharged through the top air outlet slot of the guide frame 632 and enters the recovery mechanism through the air inlet pipe connected to the top of the fan 68 to complete the waste heat recovery and heat exchange. The flue gas after heat exchange and cooling is discharged after purification treatment.
[0053] Please see Figures 1-9 The filter assembly 636 includes a filter housing 6361, the side of which is fixedly connected to the inner side of a connecting plate 631. A filter plate 6363 is slidably connected to the inner side of the filter housing 6361. Round rods 6362 are fixedly connected to both sides of the top of the filter plate 6363. The top of the round rods 6362 is slidably connected to the bottom of the connecting plate 631. A third spring 6364 is sleeved on the round rods 6362. The top of the third spring 6364 is fixedly connected to the bottom of the connecting plate 631. The bottom of spring 6364 is fixedly connected to the top of filter plate 6363. Both sides of filter plate 6363 are slidably connected to connecting shaft 6366. The other end of connecting shaft 6366 is fixedly connected to scraper 6365. The side of scraper 6365 is slidably connected to the inner side of filter plate 6363. A fourth spring 6367 is sleeved on connecting shaft 6366. One end of fourth spring 6367 is fixedly connected to the inner side of filter plate 6363, and the other end of fourth spring 6367 is fixedly connected to scraper 6365.
[0054] During the quenching process, the gas generated continuously enters the filter housing 6361 under the drive of the fan 68. When the gas flows upward, it pushes the filter plate 6363 to rise along the inner side of the filter housing 6361. The filter plate 6363 moves upward synchronously through the round rod 6362, while squeezing the third spring 6364 sleeved on the round rod 6362. The filter plate 6363 drives the scraper 6365 to contact the inner wall of the filter housing 6361 through the connecting shafts on both sides 6366. The inner wall is cleaned as the filter plate 6363 moves.
[0055] By contacting the inner wall with the scraper 6365, the dust and impurities adhering to the inner wall of the outer shell after long-term flue gas circulation are removed, preventing the accumulation of impurities from clogging the flow channel, ensuring smooth gas flow, and maintaining long-term efficient operation of the filter. At the same time, a fourth spring 6367 is provided between the scraper 6365 and the connecting shaft 6366. When the contact pressure between the scraper 6365 and the impurities on the inner wall is too large, the fourth spring 6367 will contract and buffer, driving the scraper 6365 to be slightly adjusted inward towards the filter plate 6363, avoiding wear of the scraper 6365 or damage to the inner wall of the outer shell caused by rigid compression.
[0056] When the fan 68 stops working, and the gas thrust on the filter plate 6363 is less than the reset force of the third spring 6364, the filter plate 6363 resets along the inner side of the filter housing 6361 under the action of the third spring 6364, preparing for the next filtration cleaning cycle. The whole process realizes the automatic linkage of filtration and self-cleaning, reduces the frequency of manual maintenance, and lowers the operation and maintenance costs.
[0057] Please see Figures 1-10 The recovery component 64 includes a heat exchanger 641. The bottom of the heat exchanger 641 is fixedly connected to the top of the guide frame 632. A water inlet pipe 642 is fixedly connected to one side of the heat exchanger 641, and a water outlet pipe 643 is fixedly connected to the other side of the heat exchanger 641. A smoke exhaust assembly 644 is fixedly connected to the top of the heat exchanger 641. The side of the heat exchanger 641 away from the smoke exhaust assembly 644 is fixedly connected to the top of the fan 68 through an air inlet pipe.
[0058] Under the continuous suction of the fan 68, the high-temperature flue gas in the guide frame 632 enters the heat exchanger 641 through the top air inlet pipe of the fan 68, flows through the fin structure in the heat exchanger 641, and through heat conduction, the heat of the flue gas is transferred to the working fluid inside the heat pipe, thus completing the heat release.
[0059] The heated medium enters from the inlet pipe 642 of the heat exchanger 641 and forms a counter-flow with the condensing section of the heat pipe, that is, the flow direction of the medium is opposite to that of the flue gas. It absorbs the heat transferred by the heat pipe through the fins. After absorbing the heat, the temperature of the medium rises and is transported to various energy-consuming equipment through the outlet pipe 643 to realize the utilization of waste heat.
[0060] After the flue gas has undergone heat exchange and cooling, it is then filtered and discharged through the exhaust assembly 644, thus realizing the recovery of waste heat and clean discharge of the flue gas.
[0061] Please see Figures 1-12The exhaust assembly 644 includes an exhaust pipe 6441, the side of which is fixedly connected to the inside of the heat exchanger 641. A baffle 6442 is fixedly connected to the top of the exhaust pipe 6441. A rotating rod 6443 is rotatably connected to the bottom of the baffle 6442. A rotating frame 6444 is fixedly connected to both sides of the rotating rod 6443. A fixing rod 6445 is fixedly connected to both sides of the rotating frame 6444. A cleaning brush 6446 is fixedly connected to the top of the fixing rod 6445. The top of the cleaning brush 6446 is fixedly connected to the bottom of the baffle 6442. A spiral blade 6447 is fixedly connected to the bottom of the rotating rod 6443.
[0062] As flue gas is continuously discharged through the exhaust pipe 6441, the baffle 6442 simultaneously filters and intercepts the flowing flue gas, blocking impurities in the flue gas. At the same time, when the flue gas passes through the baffle 6442, it generates an impact force on the spiral blade 6447, driving the spiral blade 6447 to rotate through the rotating rod 6443, thereby causing the rotating rod 6443 to drive the cleaning brush 6446 to dynamically contact and clean the bottom of the baffle 6442 through the fixed rod 6445.
[0063] Specific workflow:
[0064] After the raw material is released through the pay-off frame 2, the straightening component 3 eliminates bending stress to ensure straightness;
[0065] It then continues to enter the surface cleaning device to remove surface oxide scale and oil stains, so as to prevent impurities from hindering heat conduction during heating;
[0066] The pre-treated wire enters the high-frequency induction heating furnace 5, where electromagnetic induction generates eddy currents inside the wire to achieve "simultaneous heating inside and outside". The heating power is dynamically adjusted according to the wire diameter, and an infrared thermometer is used to monitor the surface temperature in real time to ensure heating accuracy.
[0067] After heating, the wire enters the quenching stage. The quenching component 6 sprays quenching oil evenly onto the surface of the wire to complete the cooling process, and simultaneously collects the residual heat from the flue gas released during the quenching process to avoid direct heat loss. Finally, after the tension is stabilized, the wire is neatly coiled by the take-up frame 7 to complete the quenching process.
[0068] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
