Description

Technical Field

[0001] This invention relates to the field of carburizing and quenching technology for wind turbine gears, specifically to a carburizing and quenching device for processing wind turbine gears. Background Technology

[0002] Carburizing and quenching is a heat treatment process used to improve the surface hardness and wear resistance of metallic materials. The entire process of carburizing and quenching wind turbine gears generally includes the following steps: after cleaning the surface of the wind turbine gears, preheating it to a suitable range, then sequentially performing carburizing, quenching, tempering, cooling and cleaning, and finally finishing.

[0003] In the quenching process mentioned above, the wind turbine gear is usually placed directly into the quenching agent for quenching. However, when the wind turbine gear is too large, the quenching agent has difficulty penetrating into the interior of the gear when it comes into contact with the gear surface, thus affecting the uniformity of quenching. Existing technology uses spray quenching to replace this. Spray quenching involves continuously spraying the quenching agent (such as water, oil or other polymer materials) onto the surface of the wind turbine gear through a nozzle or spray gun. The quenching agent cools rapidly when it comes into contact with the surface of the wind turbine gear, causing the surface of the wind turbine gear to cool and harden quickly, thereby making the quenching more uniform.

[0004] However, spray hardening requires the use of large amounts of quenching agents, such as water, oil, or other polymeric materials. These quenching agents are usually released into the environment after use, which can cause pollution. Secondly, spray hardening requires the use of high-pressure gas or water jets to spray the quenching agent, which may lead to quenching agent splashing and waste.

[0005] Therefore, we need a carburizing and quenching device for wind turbine gear processing to solve the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. This device can avoid the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. Summary of the Invention

[0011] Preferably, the reinforcing component includes a support tray, the two edges of the top of the support tray being chamfered. The support tray is located inside the water storage device. Multiple connecting blocks are fixedly connected between the support tray and the water storage device, evenly arranged around the center of the quenching cylinder.

The used quenching agent is screened by a sieve and eventually flows into the recovery cylinder. After it cools down, it can be reinjected into the water storage device through a conduit and a water pump. This solves the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. Attached Figure Description

[0032] Please see Figures 1 to 6This invention provides a technical solution: a carburizing and quenching device for wind turbine gear processing, comprising a quenching cylinder 1, characterized in that: a splash-proof component and a recovery cylinder 3 are respectively provided at the top and bottom of the quenching cylinder 1; a carburizing cylinder 2 is provided at the top of the splash-proof component; a quenching component and a reinforcing component are provided inside the quenching cylinder 1; the interior of the splash-proof component is interconnected with the recovery cylinder 3; a through-type outlet 28 is opened on one side of the inner wall of the recovery cylinder 3; a filter device is provided inside the outlet 28; a scraping component is provided on the outer wall of the quenching cylinder 1, a portion of which is located inside the quenching cylinder 1. The top of the scraping component is equipped with a drive device 19; the anti-splash component needs to be started before the quenching component. The two electric push rods 30 drive the two lead screws to slide the two anti-splash plates 31 out of the two collection slots respectively. When the two come into contact with each other, they form a sealed space with the quenching cylinder 1. The used quenching agent is screened by the sieve plate 27 and finally flows into the recovery cylinder 3. After its temperature cools down, it can be injected back into the water storage device 4 through the set conduit 12 and water pump 13, which solves the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. Example

[0033] See attached document Figures 1 to 9Based on Embodiment 1, the splash guard assembly includes two symmetrically distributed square layers 29. The two square layers 29 are fixedly connected at one end near the center of the quenching cylinder 1. Semi-circular openings are provided at both the top and bottom of the two square layers 29, forming a circular channel for the passage of the wind turbine gear. A receiving groove is provided inside each of the two square layers 29, and a splash guard plate 31 is slidably connected inside the receiving groove. A lead screw is fixedly connected to the side wall of the splash guard plate 31. An electric push rod 30 is provided at one end of the outlet 28, and the output end of the electric push rod 30 is connected to the lead screw. The quenching assembly includes a water storage device 4. The water storage device 4 is located inside the quenching cylinder 1. Multiple connecting blocks 1, evenly arranged around the center of the quenching cylinder 1, are fixedly connected to the water storage device 4 and the quenching cylinder 1. The water storage device 4 is ring-shaped with a concave top surface. Multiple water spray components are fixedly connected to the top surface of the water storage device 4. These components are equidistantly arranged around the center of the quenching cylinder 1. Each water spray component includes a spray head 9 and a water collection box 10. The spray head 9 and the water collection box 10 are fixedly connected and connected by four evenly distributed short pipes. The bottom end of each spray head 9 is fixedly connected to the top surface of the water storage device 4. One side of the water collection box 10... A curved pipe is fixedly connected to and communicates with the top surface of the water storage device 4. Each spray head 9 has four evenly distributed temporary storage slots inside, and the interior of each temporary storage slot is interconnected with the interior of each short pipe. Each temporary storage slot has multiple evenly distributed pressure-boosting openings 11 at one end near the center of the quenching cylinder 1. The cross-section of each pressure-boosting opening 11 is composed of two trapezoids, with the cross-sectional area of ​​the pressure-boosting opening 11 near the center of the quenching cylinder 1 being larger than the cross-sectional area away from the center of the quenching cylinder 1. The reinforcing component includes a support tray 5, with both edges of the top of the support tray 5 being chamfered. The support tray 5 is located at the water storage... Inside the water device 4, a number of connecting blocks 2 are fixedly connected between the support tray 5 and the water storage device 4, and are evenly arranged around the center of the quenching cylinder 1. A number of limiting protrusions 6 are fixedly connected to the top of the support tray 5, and are evenly arranged around the center of the quenching cylinder 1. Each limiting protrusion 6 has five evenly distributed flow guide openings 7 on its side wall near the center of the quenching cylinder 1. The top of the support tray 5 has a number of sets of through grooves evenly arranged around the center of the quenching cylinder 1. Each set of through grooves contains a number of evenly distributed circular holes 8, and each circular hole 8 is located next to each flow guide opening 7.

[0034] When the wind turbine gear is fixed in the appropriate position, its bottom end contacts the top surface of the support plate 5, and the gap between adjacent gear blocks is occupied by the limiting protrusions 6. The wind turbine gear is just locked between each limiting protrusion 6 to prevent displacement caused by the impact of the quenching agent, which would affect the processing. The water storage device 4 is filled with water as a quenching agent. When the water storage device 4 is activated, the water inside it will quickly flow into the interior of each bend, then into the interior of each water collection box 10, and then into the interior of each temporary storage tank through each short pipe. As the water volume in the temporary storage tank increases, this water will be sprayed out from each relatively small pressurization opening 11. Through the pressurization opening 11, just as Figure 6 As shown, when these water flows enter the center of the pressurization opening 11, the pressure on the water flow gradually increases due to the gradual reduction of the orifice diameter, thereby strengthening the impact force of the sprayed water flow and improving the quenching effect. The strong water flow will cause water to splash when it comes into contact with the tooth surface of the wind turbine gear. Since the two edges of the top of the support tray 5 are chamfered, it is easy for the water flow to fall and prevent it from stagnating on the top surface of the support tray 5, which would cause an impact or waste. The water flow between the guide opening 7 and the wind turbine gear surface will flow downward through the various circular holes 8, further solving the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. Example

[0035] See attached document Figures 1 to 9 Based on Embodiment 2, the filter assembly includes a protective box 24, which is fixedly connected to the side wall of the recovery cylinder 3. A first motor 25 is fixedly connected inside the protective box 24. A gear 1 is fixedly connected to the output shaft of the first motor 25. A gear 2 meshes with the outer wall of the gear 1. A connecting shaft is fixedly connected to the top of the gear 2. The top of the connecting shaft passes through the top of the protective box 24 and is fixedly connected to a connecting plate 26. A sieve plate 27 is fixedly connected to one end of the connecting plate 26. The outer wall of the connecting plate 26 is slidably connected to the outlet 28. The sieve plate 27 is a round block without a top surface and hollow inside with several holes at the bottom. Two symmetrically distributed water pumps 13 are arranged inside the recovery cylinder 3. The water outlet of the water pumps 13 is fixedly connected to and communicates with a conduit 12. One end of the conduit 12 passes through the interior of the recovery cylinder 3 and the quenching cylinder 1 and is fixedly communicated with the interior of the water storage device 4.

[0036] Water flowing downwards through the top edge of the support tray 5 and each of the circular holes 8 will successively flow into the inner cavity of the screen tray 27. Filtration is completed under the action of each hole. Impurities are generated when water interacts with the wind turbine gears. These impurities will remain on the inner cavity of the screen tray 27 and will not pass through. When a processing operation is completed, the first motor 25 can be started. Through the set gear one, gear two and connecting plate 26, the screen tray 27 can be slid out along the outlet 28 to the outside of the recovery cylinder 3, so as to clean up the collected impurities and facilitate subsequent processing operations. This further solves the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. Example

[0037] See attached document Figures 1 to 9 Based on Embodiment 3, this embodiment adds a scraping component;

[0038] The scraping assembly includes an arc-shaped component 18 and an arc-shaped component 20. The arc-shaped component 20 is fixedly connected to the outer wall of the quenching cylinder 1. The driving device 19 includes a second motor and a threaded rod. The second motor is fixedly connected to the outer wall of the quenching cylinder 1, and its output end is fixedly connected to the threaded rod. The bottom end of the threaded rod passes through the arc-shaped component 18 and is threadedly connected to it. The bottom end of the threaded rod is rotatably connected to the top of the arc-shaped component 20. The threaded rod is located in the middle of the arc-shaped component 18 and the arc-shaped component 20. The outer wall of the quenching cylinder 1 has two sets of threads oriented around the central axis of the threaded rod. The slide grooves are symmetrically distributed. Each set of slide grooves includes two spaced vertical grooves 14. The bottom of the vertical grooves 14 is through. A vertical block 15 and a rectangular block 16 are slidably connected on the inner wall of the vertical grooves 14. The vertical block 15 is fixedly connected to the bottom of the rectangular block 16. One end of each rectangular block 16 is fixedly connected to the arc-shaped part 18. The other end of each rectangular block 16 is fixed with the same scraper 17. The scraper 17 is located inside the quenching cylinder 1 and is slidably connected to the inner wall of the quenching cylinder 1. The top and bottom ends of the scraper 17 are chamfered.

[0039] After the quenching operation is completed, two second motors are started to drive two scraping components. Through the threaded rod, rectangular block 16 and arc-shaped component 20, the scraper 17 and arc-shaped component 18 move downward synchronously under the connection of the rectangular block 16. The scraper 17 slides down along the inner wall of the quenching cylinder 1, and the arc-shaped component 18 moves down along the outer wall of the threaded rod. Since the top and bottom of the scraper 17 are chamfered, i.e. streamlined, water is prevented from staying on the scraper 17. The water adhering to the inner wall of the quenching cylinder 1 is also scraped off, and the scraping effect is good. The scraped water will flow into the inner cavity of the recovery cylinder 3 through the gap between the quenching cylinder 1 and the water storage device 4, further solving the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. Example

[0040] See attached document Figures 1 to 9Based on Embodiment 4, this embodiment adds a striking component;

[0041] The striking assembly is located at the bottom end of the arc-shaped part 18. The striking assembly includes a vertical rod 21 and a gear 22. The top of the vertical rod 21 is fixedly connected to the bottom end of the arc-shaped part 18. The vertical rod 21 passes through the interior of the arc-shaped part 20 and is slidably connected to the interior of the arc-shaped part 20. The vertical rod 21 can be divided into upper and lower parts. The lower part of the vertical rod 21 has a first evenly distributed tooth groove on the outer wall near the gear 22. The lower part of the vertical rod 21 meshes with the gear 22. One end of the gear 22 is fixedly connected to a horizontal bar. One end of the horizontal bar passes through the interior of the quenching cylinder 1 and is rotatably connected to the interior of the quenching cylinder 1. Three sets of striking components are fixedly connected to the outer wall of the horizontal bar. Each set of striking components includes three striking blocks 23 that are equidistantly distributed with the center line of the horizontal bar as the center. The striking blocks 23 are made of rubber.

[0042] Impurities generated when water interacts with the wind turbine gears may clog some holes at the bottom of the screen disc 27, reducing the filtration effect and rate. When the scraping component is activated, the striking component is also driven by the vertical rod 21 and gear 22. That is, the vertical rod 21 moves down, causing the gear 22 to rotate and drive the horizontal rod to rotate. When the horizontal rod rotates, it drives each set of striking parts to rotate and repeatedly lifts and shakes the bottom of the screen disc 27. Because the striking block 23 is made of rubber, it avoids deformation of the bottom of the screen disc 27 under repeated striking. The repeated shaking of the screen disc 27 can lift the impurities clogging the holes, allowing water to pass through quickly, further solving the problem of quenching agent splashing into the environment during the spray quenching process, causing pollution and waste. Example

[0043] A method for using a carburizing and quenching device for processing wind turbine gears includes the following steps:

[0044] Step 1: The wind turbine gear is snapped between each limiting protrusion 6, so that its bottom end contacts the top surface of the support tray 5 and the gap between adjacent gear blocks is occupied by the limiting protrusion 6. Then the splash-proof assembly is activated, and the two electric push rods 30 drive the two lead screws to slide the two splash-proof plates 31 out of the two receiving slots respectively. When the two contact each other, they form a sealed space with the quenching cylinder 1.

[0045] Step 2: Start the water storage device 4. The water inside it will quickly flow into the interior of each bend, then into the interior of each water collection box 10, and then into the interior of each temporary storage tank through each short pipe. As the water volume in the temporary storage tank increases, the water will be sprayed out from each relatively small pressurization opening 11. The pressurization opening 11 strengthens the impact force of the sprayed water flow and improves the quenching effect.

[0046] Step 3: Start the two second motors to drive the two scraping components. Through the set threaded rod, rectangular block 16 and arc-shaped part 20, the scraper 17 and arc-shaped part 18 move downward synchronously under the connection of the rectangular block 16. The scraper 17 slides down along the inner wall of the quenching cylinder 1, and the arc-shaped part 18 moves down along the outer wall of the threaded rod. The streamlined scraper 17 prevents water from staying on its surface. The water adhering to the inner wall of the quenching cylinder 1 will also be scraped off, and the scraping effect is good. When the arc-shaped part 18 moves down, the striking components will also be driven together. That is, the vertical rod 21 moves down, causing the gear 22 to rotate and drive the horizontal rod to rotate. When the horizontal rod rotates, it will drive each set of striking parts to rotate and repeatedly lift the bottom of the screen plate 27 to make it shake, lifting the impurities blocking the holes and allowing water to pass through quickly.

[0047] Step 4: The used quenching agent is screened by the sieve 27 and eventually flows into the recovery cylinder 3. After it cools down, it can be injected back into the water storage device 4 for reuse through the set conduit 12 and water pump 13. In addition, when a processing operation is completed, the first motor 25 can be started. Through the set gear one, gear two and connecting plate 26, the sieve 27 can be slid out along the outlet 28 to the outside of the recovery cylinder 3, so as to clean the collected impurities and facilitate subsequent processing operations.
