Description

Technical Field

[0001] This invention relates to the field of heat treatment equipment technology, specifically to a heat treatment equipment for high-strength wear-resistant flange castings. Background Technology

[0002] In the field of metal processing, heat treatment is a key step in improving the performance of high-strength wear-resistant flange castings. Currently, heat treatment is a commonly used process for heating metal materials, characterized by high efficiency, speed, low energy consumption, and environmental friendliness. Traditional heat treatment equipment mainly includes high-frequency heating machines, medium-frequency induction heating equipment, and ultra-high-frequency induction heating equipment.

[0003] Existing heat treatment equipment makes it difficult to ensure uniform heating of all parts of the flange during the heating process, and quenching mainly relies on manual operation, and the fumes during quenching are often not treated. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a heat treatment equipment for high-strength wear-resistant flange castings, including an equipment base plate, an equipment support fixedly connected to the top of the equipment base plate, a quenching device fixedly connected to the top of the equipment support, and a heating device fixedly connected to the top of the equipment base plate, the heating device being positioned above the quenching device.

[0005] The quenching device includes a quenching pool, a partition plate fixedly connected to the inner wall of the quenching pool, a diversion plate fixedly connected to the top of the partition plate, a guide component connected to the bottom of the partition plate, an arc-shaped collection pool connected to the bottom of the quenching pool, a fixed end of an electric lift fixedly connected to the side of the quenching pool, a drive component fixedly connected to the movable end of the electric lift, a fixed component fixedly connected to the top of the drive component, a support component rotatably connected to the top of the fixed component, a bottom of the arc-shaped collection pool fixedly connected to the top of the equipment base plate, and a side of the quenching pool fixedly connected to the side of the equipment support.

[0006] The preferred guiding component includes a guide tube, with an arc-shaped guide block fixedly connected to the bottom of the inner wall of the guide tube. A trapezoidal opening is provided on the side of the guide tube, and the top of the guide tube is connected to the bottom of the partition plate.

[0007] Preferably, the drive assembly includes a connecting base plate. A first worm gear is rotatably connected to the side of the connecting base plate via a bracket. A turntable handle is fixedly connected to the side of the first worm gear. A first worm wheel meshes with the bottom of the first worm gear. A drive shaft is fixedly connected to the side of the first worm wheel. A second worm gear is fixedly connected to the end of the drive shaft away from the first worm wheel. A second worm wheel meshes with the side of the second worm gear. A base plate bracket is rotatably connected to the bottom of the second worm wheel. The second worm gear is rotatably connected to the top of the base plate bracket via a bracket. The side of the connecting base plate is fixedly connected to the moving end of the electric lifter. The top of the second worm wheel is fixedly connected to the bottom of the fixed assembly.

[0008] Preferably, the fixing assembly includes a lower base plate, the top of which has an arc-shaped sliding hole, and an upper top plate rotatably connected to the top of the lower base plate. The top of the upper top plate has a straight sliding hole, and a sliding shaft is slidably connected to the inner wall of the arc-shaped sliding hole. The top of the upper top plate has a fixed shaft, and the upper top plate is fixedly connected to the top of the base plate bracket. The bottom of the lower base plate is fixedly connected to the top of the second worm gear, and a support assembly is rotatably connected to the top of the sliding shaft.

[0009] The preferred support assembly includes a movable base plate, with sliding strips fixedly connected to both sides of the bottom of the movable base plate, and limit strips fixedly connected to both sides of the top of the movable base plate. A support base is rotatably connected to the top of the movable base plate, and a support rod is fixedly connected to the top of the support base. An arc-shaped support strip is fixedly connected to the top of the support rod. The bottom of the movable base plate is fixedly connected to the top of the sliding shaft. The movable base plate is slidably connected to the top of the upper top plate via the sliding strips. The rotation of the second worm gear drives the lower base plate and the upper top plate to rotate relative to each other, thereby driving the sliding shaft to slide along the inner wall of the arc-shaped sliding hole and the straight sliding hole. This drives multiple sets of sliding shafts to move synchronously, thereby fixing the flange from multiple directions and ensuring uniform force distribution at different angles inside the flange, thus avoiding deformation caused by uneven force distribution after the metal heats up. The sliding shaft moves, causing the moving base plate to move. The moving base plate is slidably connected to the inner wall of the flange via a sliding strip. The movement of the moving base plate causes the support base to move, which in turn presses and fixes the inner ring of the flange. The rotational connection between the support base and the moving base plate allows the support base to rotate at a certain angle on top of the moving base plate. The rotation angle of the support base is limited by the limit strip, ensuring that the support rod has free movement within a certain angle range when it contacts the inner wall of the flange. The arc design of the arc-shaped support strip ensures a certain angle of guidance, keeping the flange stable on the side of the support rod. This ensures the stability of the flange during quenching and prevents it from loosening during movement. After quenching, the flange can be removed from the quenching tank for further tempering or subsequent processing.

[0010] Preferably, the heating device includes a support frame, a heating shell fixedly connected to the side of the support frame, a guide plate fixedly connected to the bottom of the heating shell, a heating outer ring fixedly connected to the inner wall of the heating shell, a heating column fixedly connected to the top of the inner wall of the support frame, a heating inner ring fixedly connected to the side of the heating column, an exhaust device connected to the top of the heating shell, a collection device connected to the side of the exhaust device, a bottom of the exhaust device fixedly connected to the top of the support frame, a bottom of the collection device fixedly connected to the top of the support frame, and a bottom of the support frame fixedly connected to the top of the equipment base plate.

[0011] Preferably, the exhaust device includes an active fan, an upper gear ring fixedly connected to the bottom of the active fan, a reversing gear meshing at the bottom of the upper gear ring, a lower gear ring meshing at the bottom of the reversing gear, a driven fan fixedly connected to the bottom of the lower gear ring, and a fixed shaft rotatably connected to the side of the reversing gear. The heating device also includes a fan housing, the bottom of which is fixedly connected to the top of the support frame, and the bottom of the fixed shaft is fixedly connected to the top of the support frame.

[0012] The preferred collection device includes an air guide shell, with a water storage tank at the top. A water droplet pipe is connected and fixedly attached to the inner wall of the water storage tank. A drum filter element is fixedly connected to the side of the water droplet pipe. An air inlet adapted to the drum filter element is located on the side of the air guide shell, and an air outlet is located on the side of the air inlet. The side of the air guide shell communicates with the side of the fan shell. When the outer and inner heating rings are activated, an electric lifter raises the flange. The outer heating ring heats the outer ring of the flange, and the inner heating ring heats the inner ring of the flange, thus heating the flange bidirectionally. This improves heating efficiency compared to traditional heating methods. During quenching, an active fan is activated, and the active fan rotates to drive the upper... The upper gear ring rotates, driving the reversing gear to rotate, which in turn drives the lower gear ring to rotate. The lower gear ring then drives the driven fan to rotate, which in turn moves the quenching fumes. The active fan draws air down from above to mix with the fumes, thus lowering their temperature. Wind pressure is generated inside the fan housing, causing the air to flow along the inlet. The fumes pass through the inner wall of the inlet and enter the drum filter element. The drum filter element adsorbs the fumes, causing them to accumulate inside. Water is guided through a drip irrigation system to keep the inner wall of the drum filter element moist, ensuring effective adsorption and cooling of the fumes. This facilitates fume collection and reduces pollution.

[0013] This invention provides a heat treatment device for high-strength wear-resistant flange castings. It has the following beneficial effects:

[0014] 1. The heat treatment equipment for this high-strength wear-resistant flange casting is equipped with an electric lifter. The moving end of the electric lifter drives the lifting or lowering of the casting, and the moving drive component drives the fixed component to lift or lower. The quenching tank is filled with quenching liquid, which submerges the top of the partition plate. During quenching, impurities are guided by the guide component and fall under the action of gravity, thus allowing the impurities to settle to the bottom. The design of the guide component prevents impurities from flowing back into the top of the partition plate, thereby preventing impurities from flowing back into the upper layer of the quenching liquid. This ensures that the quenching liquid layer remains pure, which is beneficial to ensuring the quenching quality.

[0015] 2. The heat treatment equipment for this high-strength wear-resistant flange casting is equipped with a guide pipe. The quenching liquid passes through the inner wall of the guide pipe and is guided by the arc-shaped guide block to descend, thereby causing impurities to fall under the action of gravity and accumulate at the top of the arc-shaped collection pool. Furthermore, the trapezoidal design of the arc-shaped guide block prevents impurities from flowing back along the inner wall of the guide pipe.

[0016] 3. The heat treatment equipment for this high-strength wear-resistant flange casting is equipped with a turntable handle. Manually rotating the handle rotates the first worm gear, which in turn rotates the first worm wheel. The first worm wheel then rotates the drive shaft, which in turn rotates the second worm gear, which in turn rotates the second worm wheel. This rotation, along with the worm wheel-worm gear engagement between the first and second worm gears, ensures the flange's self-locking function after fixing. Furthermore, during flange heating, the engagement between the first worm gear and the turntable handle is kept away from the heating zone, preventing self-locking failure due to heating. This ensures the flange remains stable during heating and avoids deformation during quenching after heating, thus preventing issues with product quality.

[0017] 4. The heat treatment equipment for this high-strength wear-resistant flange casting is equipped with a second worm gear. The rotation of the second worm gear drives the lower base plate and the upper top plate to rotate relative to each other, thereby driving the sliding shaft to slide along the inner wall of the arc-shaped sliding hole and the straight sliding hole. This causes multiple sets of sliding shafts to move synchronously, thus fixing the flange from multiple directions and ensuring that the flange is subjected to uniform force at different angles inside, thereby avoiding deformation caused by uneven force after the metal is heated. The movement of the sliding shaft drives the movement of the moving base plate, which is slidably connected to the inner wall of the flange through a sliding strip. The movement of the moving base plate drives the movement of the support base, which compresses and fixes the inner ring of the flange. The rotational connection between the support base and the moving base plate allows the support base to rotate at a certain angle on the top of the moving base plate. The rotation angle of the support base is limited by the limit strip, thus ensuring that the support rod has free movement within a certain angle range when it contacts the inner wall of the flange.

[0018] 5. The heat treatment equipment for this high-strength wear-resistant flange casting is equipped with an outer heating ring and an inner heating ring. When the outer and inner heating rings are activated, the electric lifter raises the flange. The outer heating ring heats the outer ring of the flange, and the inner heating ring heats the inner ring, thus heating the flange bidirectionally. This improves heating efficiency compared to traditional heating methods. During quenching, the active fan is activated. The rotation of the active fan drives the upper gear ring to rotate, which in turn drives the reversing gear to rotate. The reversing gear then drives the lower gear ring to rotate, which in turn drives the driven fan to rotate. The driven fan moves the quenching fumes, and the active fan drives air to descend from above and mix with the fumes, thereby reducing the temperature of the fumes.

[0019] 6. The heat treatment equipment for this high-strength wear-resistant flange casting is equipped with a fan housing. The air pressure generated inside the fan housing drives the air to flow along the air inlet. The flue gas enters the interior of the drum filter element through the inner wall of the air inlet. The drum filter element adsorbs the flue gas, causing it to accumulate inside. Water is guided by a water droplet to keep the inner wall of the drum filter element moist, thus ensuring the adsorption effect and cooling the flue gas, facilitating its collection and reducing pollution.

Detailed Implementation

[0031] 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.

[0032] Please see Figures 1-2 The present invention provides a technical solution: a heat treatment equipment for high-strength wear-resistant flange castings, including an equipment base plate 1, an equipment support 2 fixedly connected to the top of the equipment base plate 1, a quenching device 3 fixedly connected to the top of the equipment support 2, and a heating device 4 fixedly connected to the top of the equipment base plate 1, the heating device 4 being positioned above the quenching device 3.

[0033] The equipment base plate 1 and equipment bracket 2 provide overall support for the equipment. The quenching device 3 fixes the flange. The heating device 4 performs high-frequency heating on the inner and outer rings of the flange, so that the flange is heated simultaneously inside and out, thus ensuring uniform heating. The quenching device 3 also fixes and limits flanges of different sizes, ensuring that flanges of different diameters receive the same heating conditions, thus ensuring uniform heating. The heat treatment is carried out by directly quenching the flanges as they descend. The heating device 4 collects and treats the residue from the heat treatment process, thus ensuring the quality of quenching.

[0034] The quenching device 3 includes a quenching pool 301. A partition plate 302 is fixedly connected to the inner wall side of the quenching pool 301. A diversion plate 303 is fixedly connected to the top of the partition plate 302. A guide component 304 is connected to the bottom of the partition plate 302. An arc-shaped collection pool 305 is connected to the bottom of the quenching pool 301. The fixed end of an electric lifter 306 is fixedly connected to the side of the quenching pool 301. A drive component 307 is fixedly connected to the movable end of the electric lifter 306. A fixing component 308 is fixedly connected to the top of the drive component 307. A support component 309 is rotatably connected to the top of the fixing component 308. The bottom of the arc-shaped collection pool 305 is fixedly connected to the top of the equipment base plate 1. The side of the quenching pool 301 is fixedly connected to the side of the equipment support 2.

[0035] When the electric lift 306 is activated, the moving end of the electric lift 306 drives the drive component 307 to rise or fall. The movement of the drive component 307 drives the fixed component 308 to rise or fall. The quenching pool 301 contains quenching liquid, which submerges the top of the partition plate 302. During quenching, impurities are guided by the guide component 304 and fall under the action of gravity, thus allowing the impurities to settle to the bottom. The design of the guide component 304 also prevents impurities from flowing back into the top of the partition plate 302, thereby preventing impurities from flowing back into the upper layer of the quenching liquid. This ensures that the quenching liquid remains pure, which is beneficial to ensuring the quenching quality.

[0036] Please see Figures 1-4 The present invention provides a technical solution: the guide component 304 includes a guide tube 3041, an arc-shaped guide block 3042 is fixedly connected to the bottom of the inner wall of the guide tube 3041, a trapezoidal opening 3043 is provided on the side of the guide tube 3041, and the top of the guide tube 3041 is connected to the bottom of the partition plate 302.

[0037] The drive assembly 307 includes a connecting base plate 3071. A first worm gear 3072 is rotatably connected to the side of the connecting base plate 3071 via a bracket. A turntable handle 3073 is fixedly connected to the side of the first worm gear 3072. A first worm wheel 3074 is meshed with the bottom of the first worm gear 3072. A drive shaft 3075 is fixedly connected to the side of the first worm wheel 3074. A second worm gear 3076 is fixedly connected to the end of the drive shaft 3075 away from the first worm wheel 3074. A second worm wheel 3077 is meshed with the side of the second worm gear 3076. A base plate bracket 3078 is rotatably connected to the bottom of the second worm wheel 3077. The second worm gear 3076 is rotatably connected to the top of the base plate bracket 3078 via a bracket. The side of the connecting base plate 3071 is fixedly connected to the moving end of the electric lift 306. The top of the second worm wheel 3077 is fixedly connected to the bottom of the fixing assembly 308.

[0038] The quenching liquid flows through the inner wall of the guide pipe 3041 and is guided by the arc-shaped guide block 3042, causing the liquid to descend. This allows impurities to fall under gravity and accumulate at the top of the arc-shaped collection pool 305. The trapezoidal design of the arc-shaped guide block 3042 prevents impurities from flowing back along the inner wall of the guide pipe 3041. Manually turning the turntable handle 3073 rotates the first worm gear 3072, which in turn rotates the first worm wheel 3074. The first worm wheel 3074 rotates the drive shaft 3075, which in turn rotates the second worm gear 3076. The rotation of the second worm gear 3076 drives the second worm wheel 3077 to rotate, thereby causing the fixing component 308 to rotate. The worm wheel and worm gear cooperation between the first worm wheel 3074 and the first worm gear 3072, and between the second worm gear 3076 and the second worm wheel 3077, achieves the self-locking function of the flange after it is fixed. During the flange heating process, the cooperation between the first worm gear 3072 and the turntable handle 3073 is away from the heating zone, thereby avoiding self-locking failure caused by heating. This ensures that the flange maintains a stable state during the heating process, thus preventing deformation of the flange during the quenching process after heating, which would affect the yield.

[0039] Please see Figures 1-6The present invention provides a technical solution: the fixing component 308 includes a lower base plate 3081, an arc-shaped sliding hole 3082 is provided on the top of the lower base plate 3081, an upper top plate 3083 is rotatably connected to the top of the lower base plate 3081, a straight sliding hole 3084 is provided on the top of the upper top plate 3083, a sliding shaft 3085 is slidably connected to the inner wall of the arc-shaped sliding hole 3082, a limiting slide 3086 is provided on the top of the upper top plate 3083, the upper top plate 3083 is fixedly connected to the top of the base plate bracket 3078 through a fixing shaft, the bottom of the lower base plate 3081 is fixedly connected to the top of the second worm gear 3077, and a support component 309 is rotatably connected to the top of the sliding shaft 3085.

[0040] The support assembly 309 includes a movable base plate 3091, with slide bars 3092 fixedly connected to both sides of the bottom of the movable base plate 3091, limit bars 3093 fixedly connected to both sides of the top of the movable base plate 3091, a support base 3094 rotatably connected to the top of the movable base plate 3091, a support rod 3095 fixedly connected to the top of the support base 3094, an arc-shaped support bar 3096 fixedly connected to the top of the support rod 3095, the bottom of the movable base plate 3091 fixedly connected to the top of the sliding shaft 3085, and the movable base plate 3091 slidably connected to the top of the upper top plate 3083 via the slide bars 3092.

[0041] The rotation of the second worm gear 3077 causes relative rotation between the lower base plate 3081 and the upper top plate 3083, thereby causing the sliding shaft 3085 to slide along the inner wall of the arc-shaped sliding hole 3082 and the straight sliding hole 3084. This causes multiple sets of sliding shafts 3085 to move synchronously, thus fixing the flange from multiple directions and ensuring uniform force distribution at different angles inside the flange. This avoids deformation caused by uneven force distribution after the metal heats up. The movement of the sliding shaft 3085 causes the moving base plate 3091 to move. The moving base plate 3091 is slidably connected to the inner wall of the limiting slide 3086 through the sliding strip 3092. The movement of the moving base plate 3091 causes the support base 3094 to move, and the movement of the support base 3094 squeezes the inner ring of the flange. The support base 3094 is fixed in place and rotated with the movable base plate 3091 through a support base 3094, allowing the support base 3094 to rotate at a certain angle on top of the movable base plate 3091. The rotation angle of the support base 3094 is limited by the limit strip 3093, thus ensuring that the support rod 3095 has free movement within a certain angle range when it contacts the inner wall of the flange. Furthermore, the arc design of the arc-shaped support strip 3096 ensures a certain angle of guidance, keeping the flange stable on the side of the support rod 3095. This ensures the stability of the flange during moving and quenching, preventing loosening during movement. This ensures that after quenching, the flange can be moved out of the quenching pool 301 for the next step of tempering or subsequent processing.

[0042] Please see Figures 1-9 The present invention provides a technical solution: the heating device 4 includes a support frame 401, a heating shell 402 is fixedly connected to the side of the support frame 401, a guide plate 403 is fixedly connected to the bottom of the heating shell 402, a heating outer ring 404 is fixedly connected to the inner wall of the heating shell 402, a heating column 405 is fixedly connected to the top of the inner wall of the support frame 401, a heating inner ring 406 is fixedly connected to the side of the heating column 405, an exhaust device 407 is connected to the top of the heating shell 402, a collection device 408 is connected to the side of the exhaust device 407, the bottom of the exhaust device 407 is fixedly connected to the top of the support frame 401, the bottom of the collection device 408 is fixedly connected to the top of the support frame 401, and the bottom of the support frame 401 is fixedly connected to the top of the equipment base plate 1.

[0043] The exhaust device 407 includes an active fan 4071, an upper gear ring 4072 fixedly connected to the bottom of the active fan 4071, a reversing gear 4073 meshing with the bottom of the upper gear ring 4072, a lower gear ring 4074 meshing with the bottom of the reversing gear 4073, a driven fan 4075 fixedly connected to the bottom of the lower gear ring 4074, and a fixed shaft 4076 rotatably connected to the side of the reversing gear 4073. The heating device 4 also includes a fan housing 4077, the bottom of the fan housing 4077 fixedly connected to the top of the support frame 401, and the bottom of the fixed shaft 4076 fixedly connected to the top of the support frame 401.

[0044] The collection device 408 includes an air guide shell 4081, a water storage tank 4082 is provided on the top of the air guide shell 4081, a water drop pipe 4083 is connected through and fixed to the inner wall of the water storage tank 4082, a roller filter element 4084 is fixedly connected to the side of the water drop pipe 4083, an air inlet 4085 adapted to the roller filter element 4084 is provided on the side of the air guide shell 4081, an air outlet 4086 is provided on the part of the air guide shell 4081 located on the side of the air inlet 4085, and the side of the air guide shell 4081 is connected to the side of the fan shell 4077.

[0045] The outer heating ring 404 and the inner heating ring 406 are activated. The electric lifter 306 raises the flange. The outer heating ring 404 heats the outer ring of the flange, and the inner heating ring 406 heats the inner ring, thus heating the flange bidirectionally. This improves heating efficiency compared to traditional heating methods. During quenching, the active fan 4071 is activated. The rotation of the active fan 4071 drives the upper gear ring 4072 to rotate, which in turn drives the reversing gear 4073 to rotate. The reversing gear 4073 then drives the lower gear ring 4074 to rotate, which in turn drives the driven fan 4075 to rotate. The driven fan 4075 then dissipates the fumes generated during quenching. The dust moves, and the active fan 4071 drives air downwards to mix with the dust, thereby reducing the temperature of the dust. The air pressure generated inside the fan housing 4077 drives the air to flow along the air inlet 4085. The dust enters the interior of the drum filter element 4084 through the inner wall of the air inlet 4085. The drum filter element 4084 adsorbs the dust, causing it to accumulate inside. Water is guided by the water droplet 4083 to keep the inner wall of the drum filter element 4084 moist, thus ensuring the adsorption effect and cooling the dust, facilitating dust collection and reducing pollution.

[0046] Please see Figures 1-10 This invention provides a technical solution: a heat treatment device and process for high-strength wear-resistant flange castings, comprising the following steps:

[0047] S1. Start the electric lift 306. The moving end of the electric lift 306 drives the drive component 307 to rise or fall. The moving drive component 307 drives the fixed component 308 to rise or fall. The quenching pool 301 contains quenching liquid. The liquid submerges the top of the partition plate 302. During quenching, impurities fall through the guide component 304 under the action of gravity.

[0048] S2. The quenching liquid flows through the inner wall of the guide pipe 3041 and is guided by the arc-shaped guide block 3042 to descend, causing impurities to fall under the action of gravity and accumulate at the top of the arc-shaped collection pool 305. The trapezoidal design of the arc-shaped guide block 3042 prevents impurities from flowing back along the inner wall of the guide pipe 3041. The turntable handle 3073 is manually rotated, which drives the first worm 3072 to rotate. The first worm 3072 drives the first worm wheel 3074 to rotate. The first worm wheel 3074 drives the transmission shaft 3075 to rotate. The transmission shaft 3075 drives the second worm 3076 to rotate. The second worm 3076 drives the second worm wheel 3077 to rotate.

[0049] S3. The rotation of the second worm gear 3077 causes the lower base plate 3081 and the upper top plate 3083 to rotate relative to each other, thereby causing the sliding shaft 3085 to slide along the inner wall side of the arc-shaped sliding hole 3082 and the straight sliding hole 3084, thereby causing multiple sets of sliding shafts 3085 to move synchronously, thereby fixing the flange from multiple directions. The movement of the sliding shaft 3085 causes the moving base plate 3091 to move. The moving base plate 3091 is slidably connected to the inner wall of the limiting slide 3086 through the sliding strip 3092. The movement of the moving base plate 3091 causes the support base 3094 to move. The movement of the support base 3094 presses and fixes the inner ring of the flange, and restricts the rotation angle of the support base 3094 under the restriction of the limiting strip 3093.

[0050] S4. Start heating the outer ring 404 and the inner ring 406. The electric lifter 306 drives the flange to rise. The outer ring 404 heats the outer ring of the flange, and the inner ring 406 heats the inner ring of the flange, thus heating the flange bidirectionally. During quenching, start the active fan 4071. The rotation of the active fan 4071 drives the upper gear ring 4072 to rotate. The rotation of the upper gear ring 4072 drives the reversing gear 4073 to rotate. The rotation of the reversing gear 4073 drives the lower gear ring 407... 4. Rotation: The lower gear ring 4074 rotates, driving the driven fan 4075 to rotate. The driven fan 4075 rotates, causing the quenching fumes to move. The active fan 4071 drives air to descend from above and mix with the fumes. Wind pressure is generated inside the fan housing 4077, causing the air to flow along the air inlet 4085. The fumes pass through the inner wall of the air inlet 4085 and enter the interior of the drum filter element 4084. The drum filter element 4084 adsorbs the fumes, thus completing the adsorption of the fumes.

7. A heat treatment process for high-strength wear-resistant flange castings, characterized in that, Includes the following steps: S1. Start the electric lift. The moving end of the electric lift will drive the rise or fall. The drive component will move and drive the fixed component to rise or fall. The interior of the quenching tank is filled with quenching liquid. The liquid is submerged at the top of the partition plate. During quenching, impurities will fall under the action of gravity through the guide component. S2. The quenching liquid flows through the inner wall of the guide pipe and is guided by the arc-shaped guide block to descend, causing impurities to fall under the action of gravity and accumulate at the top of the arc-shaped collection pool. The trapezoidal design of the arc-shaped guide block prevents impurities from flowing back along the inner wall of the guide pipe. The turntable handle is manually turned, which drives the first worm to rotate, which in turn drives the first worm wheel to rotate, which in turn drives the drive shaft to rotate, which in turn drives the second worm to rotate, which in turn drives the second worm wheel to rotate. S3. The rotation of the second worm gear causes relative rotation between the lower base plate and the upper top plate, thereby causing the sliding shaft to slide along the inner wall side of the arc-shaped sliding hole and the straight sliding hole, thereby causing multiple sets of sliding shafts to move synchronously, thus fixing the flange from multiple directions. The movement of the sliding shaft causes the moving base plate to move. The moving base plate is slidably connected to the inner wall through the sliding strip. The movement of the moving base plate causes the support base to move. The movement of the support base squeezes and fixes the inner ring of the flange, and the rotation angle of the support base is limited by the limit strip. S4. Start the heating outer ring and heating inner ring. The electric lifter drives the flange to rise. The heating outer ring heats the outer ring of the flange, and the heating inner ring heats the inner ring of the flange, thus heating the flange bidirectionally. During quenching, start the active fan. The rotation of the active fan drives the upper gear ring to rotate, which in turn drives the reversing gear to rotate. The reversing gear drives the lower gear ring to rotate, which in turn drives the driven fan to rotate. The driven fan moves the quenching fumes. The active fan drives the air to fall from above and mix with the fumes. The air pressure generated inside the fan housing drives the air to flow along the air inlet. The fumes enter the interior of the drum filter element through the inner wall of the air inlet and are adsorbed by the drum filter element.
