Description

Technical Field

[0001] This invention relates to the field of heat treatment technology for flange forgings, specifically to a spray cooling device for heat-treated flange forgings. Background Technology

[0002] Forged flanges are among the flange products with the best mechanical properties. Their raw material is generally a pipe blank, which is then cut and repeatedly hammered to eliminate defects such as segregation and porosity in the steel ingot. Their price and mechanical properties are a grade higher than ordinary cast flanges. Flanges are parts used to connect pipes to each other and valves, attached to the pipe ends; they are also used on equipment inlets and outlets, connecting two pieces of equipment. Forged flanges are primarily made of carbon steel and alloy steel. Steel and stainless steel are mainly categorized according to national standards, electrical standards, American standards, German standards, and Japanese standards. The main anti-corrosion treatments include oiling and galvanizing. Forged flanges have good pressure and temperature resistance and are generally suitable for high-pressure and high-temperature working environments. Heat treatment refers to a metal heat treatment process that uses heating, holding, and cooling methods to obtain the desired microstructure and properties of materials in a solid state. The role of heat treatment was gradually recognized during the transition from the Stone Age to the Bronze Age and Iron Age. Heat-treated flange forgings often require cooling treatment before further production operations can proceed.

[0003] For example, patent document CN 114888233 B discloses a cold water jet type cooling device for wind turbine flange forging. It includes a fixing device and a spraying device disposed on one side of the fixing device. The fixing device includes a clamping mechanism, a driven mechanism on one side of the clamping mechanism, and a locking mechanism on one side of the driven mechanism. This invention can rotate the flange in two directions while spraying water to cool it, avoiding dead zones on the flange surface that would lead to uneven cooling. Simultaneously, the continuous rotation of the flange during cooling quickly dissipates water vapor adhering to and near the flange surface, rapidly reducing the temperature around the flange. Furthermore, the cooling water can directly contact the flange surface, greatly increasing the cooling effect.

[0004] However, when this structure is used for actual heat treatment of flange forgings, due to its structural limitations, it can only achieve cooling by directly spraying water onto the flange forging surface. The sprayed cooling mist cannot flow efficiently on the inner and outer surfaces of the flange forging, and the mist mixes directly with steam, causing abnormal flow problems. This results in insufficient contact with the flange forging surface, leading to a long cooling time and affecting the overall heat treatment efficiency of the flange forgings. At the same time, the equipment cannot perform more suitable positioning and loading / unloading operations for the flange forgings, and the stability of all flange forgings cannot be effectively guaranteed during the spray cooling process, failing to meet daily usage requirements. Therefore, there is an urgent need to design a spray cooling device for heat-treated flange forgings to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a spray cooling device for heat-treated flange forgings, which solves the problems mentioned in the background art. Existing structures, due to their structural limitations, often only allow for direct spraying onto the flange forging surface to achieve cooling. The sprayed cooling mist cannot flow efficiently across the inner and outer surfaces of the flange forgings; the mist mixes directly with steam, causing abnormal flow and insufficient contact with the flange forging surface. This results in a longer cooling time for the flange forgings, affecting the overall heat treatment efficiency of the equipment. Furthermore, the equipment cannot provide more suitable positioning and loading / unloading operations for the flange forgings, and the spray cooling process cannot effectively guarantee the stability of all flange forgings, failing to meet daily usage requirements.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This heat-treated flange forging spray cooling device, through the inclusion of a first mounting base, a second mounting base, a support base, a support frame, a guide bracket, a flow turbine fan, an annular atomizing nozzle, a central atomizing nozzle, an arc-shaped docking seat, a load-bearing arc cover, a movable shaft, a flip-up arc cover, a lifting handle, an air intake mesh groove, an air distribution duct, a flow channel, an upper arc-shaped airbag, a lower arc-shaped airbag, a first sealing strip, a second sealing strip, a third sealing strip, a sealing blind groove, and a sealing through groove, allows the equipment to perform a spray cooling operation on the heat-treated flange forging with more complete contact between the water mist and the flow. In actual use, the operator first feeds the heat-treated flange forging into the first and second mounting seats via the bearing arc cover and the moving frame, along the guide inclined frame fitted on the support base. Initial positioning and docking are achieved through the arc-shaped mating seat between the two. Then, the rotating arc cover is rotated via the movable shaft for a rotating and sealing operation. At this point, the arc-shaped mating seat, the bearing arc cover, and the rotating arc cover are fully fitted and sealed through the first, second, and third sealing strips on their respective edges, ensuring airflow sealing between the first and second mounting seats. Then, the air pumps on one side of the first and second mounting seats can be started simultaneously, drawing air from the air intake slot. Air is then pumped through the upper and lower air ducts on the sides to the upper and lower arc-shaped airbags located near each other on the first and second mounting seats, respectively. The upper arc-shaped airbag aligns with the sealing blind grooves at both ends of the rotating arc cover, while the lower arc-shaped airbag passes directly through the sealing groove of the arc-shaped mating seat, directly mating and sealing with both ends of the bearing arc cover, thus ensuring the airflow sealing between the bearing arc cover and the rotating arc cover. The heat-treated flange forging inside the arc cover is stably and reliably sealed. Simultaneously, the liquid pumps and flow turbines at both ends are started to quickly atomize the cooling water. The water is then sprayed onto the inside and outside of the heat-treated flange forging through the annular atomizing nozzles at the edge and center of one end, as well as the central atomizing nozzle. The design of the two sets of flow turbines allows the mist to undergo high-speed vortex operation between the first and second mounting seats, greatly improving the spray cooling effect on the heat-treated flange forging and enhancing the overall cooling efficiency of the equipment, demonstrating the practicality of the equipment design.

[0019] This heat-treated flange forging spray cooling device, through the inclusion of a liquid control pump, sleeve cover, liquid storage tank, shrink seat, support air cushion, moving wheels, adjusting slide, support arc strip, diverter pipe, air control pump, top air bag, top block, inflation pump, plug groove, plug valve port, sleeve groove, first connecting thread, first sealing ring, second connecting thread, second sealing ring, plug connector, adjusting handle, and shrink groove, further improves the overall performance of the equipment. In daily use, operators can place the high-temperature heat-treated flange forging into the bearing arc cover. Beforehand, the support arc strip inside the bearing arc cover can be adjusted using the adjusting slide to adapt and support the bottom of the heat-treated flange forging one by one. Then, the moving frame at the bottom of the bearing arc cover is used for loading and unloading between the first and second mounting seats. The moving frame moves via the bottom moving wheels. After moving to the designated position, the support air cushion inside the shrink seat is activated to achieve the desired fit. The ground support and fixing operation is completed. After the bearing arc cover and the moving frame are moved between the first and second mounting bases, the air pump on the back of the diversion pipe can be started to inflate the top airbag inside the shrink groove of the support base. The top block at one end of the top airbag can fix the two ends of the moving frame, thereby quickly completing the loading and fixing operation of the bearing arc cover and the moving frame, avoiding abnormal loosening problems during subsequent heat treatment flange forging spray cooling. At the same time, the two sets of liquid storage tanks can be inserted and installed into the sleeve covers at both ends of the first and second mounting bases respectively. The liquid storage tank is screwed and positioned to the first connecting thread on the inner wall of the sleeve groove through the second connecting thread on one side. The plug at one end is directly connected to the plug valve port of the plug groove at one end of the liquid pump. The first sealing ring and the second sealing ring are mated to ensure the tight connection between the sleeve cover and the liquid storage tank. This design allows for quick replacement and recovery of the cooling water inside the liquid storage tank, meeting daily use needs. Attached Figure Description

Simultaneously, the liquid control pumps 6 and the flow turbine fans 9 at both ends are started to quickly atomize the cooling water. The water is then sprayed onto the inside and outside of the heat-treated flange forging through the annular atomizing nozzles 10 and the central atomizing nozzle 11 at the edge and center of one end, respectively. The design of the two sets of flow turbine fans 9 allows the mist to undergo high-speed vortex operation between the first mounting base 1 and the second mounting base 2, greatly improving the spray cooling effect of the equipment on the heat-treated flange forging.

[0034] An arc-shaped docking seat 12 is fixedly connected to the bottom of one end of the first mounting seat 1 and the second mounting seat 2, which are close to each other. A bearing arc cover 13 is movably connected between the arc-shaped docking seats 12. A movable frame 14 is fixedly connected to the bottom end of the bearing arc cover 13. A movable shaft 15 is provided on the back of the arc-shaped docking seat 12. A flip-up arc cover 16 is movably connected to the top of the arc-shaped docking seat 12 through the movable shaft 15.

An adjusting groove 21 is opened on the inner wall of the bearing arc cover 13. Multiple sets of supporting arc strips 22 are movably connected inside the adjusting groove 21. A diversion pipe 23 is fixedly connected to the back of the supporting base 4. A control air pump 24 is provided on the back of the diversion pipe 23.

The support air cushion 19 inside the shrinkage seat 18 is activated to achieve the support and fixation operation with the ground. When the bearing arc cover 13 and the moving frame 14 are moved between the first mounting seat 1 and the second mounting seat 2, the air pump 24 on the back of the diversion pipe 23 can be activated to inflate the top-mounted airbag 25 inside the shrinkage groove 42 of the support base 3. The top-mounted block 26 at one end of the top-mounted airbag 25 can fix the two ends of the moving frame 14, thereby quickly completing the loading and fixing operation of the bearing arc cover 13 and the moving frame 14.

[0035] Working principle: During use, the operator first feeds the heat-treated flange forging into the interior of the first mounting base 1 and the second mounting base 2 via the bearing arc cover 13 and the movable frame 14, along the guide inclined frame 5 fitted on the support base 4. Initial positioning and docking are achieved through the arc-shaped docking seat 12 between the two. Then, the rotating arc cover 16 is rotated and connected via the movable shaft 15. At this time, the arc-shaped docking seat 12, the bearing arc cover 13, and the rotating arc cover 16 are fully fitted and sealed through the first sealing strip 43, the second sealing strip 44, and the third sealing strip 45 on their respective edges, ensuring the airflow between the first mounting base 1 and the second mounting base 2 is sealed. Afterwards, the air pump 2 on one side of the first mounting base 1 and the second mounting base 2 can be started simultaneously. 7. Air is drawn in from the suction mesh groove 28, and then inflated through the side air distribution ducts 29 to the upper arc-shaped airbags 31 and 32 at the upper and lower ends of the first mounting base 1 and the second mounting base 2, respectively. The upper arc-shaped airbag 31 then aligns with the sealing blind grooves 46 at both ends of the flip-up arc cover 16, while the lower arc-shaped airbag 32 passes directly through the sealing through groove 47 of the arc-shaped docking seat 12 and directly aligns with both ends of the bearing arc cover 13 to ensure a stable and reliable sealing connection between the bearing arc cover 13 and the heat-treated flange forging inside the flip-up arc cover 16. At the same time, the liquid control pumps 6 and the flow turbine fan 9 at both ends are started to quickly atomize the cooling water, which is then atomized through the annular atomizing nozzles 10 at the edge and center of one end and the central mist nozzle. The spray nozzles 11 spray the heat-treated flange forgings both inside and out. The design of two sets of flow turbine fans 9 allows the mist to undergo high-speed vortex operation between the first mounting base 1 and the second mounting base 2, greatly improving the spray cooling effect on the heat-treated flange forgings. During daily use, operators can place the high-temperature heat-treated flange forgings into the support arc cover 13. Beforehand, the support arc strips 22 inside the support arc cover 13 can be adjusted using the sliding groove 21 to adapt and support the bottom of the heat-treated flange forgings one by one. Then, the moving frame 14 at the bottom of the support arc cover 13 is used for loading and unloading between the first mounting base 1 and the second mounting base 2. The moving frame 14 is supported by the bottom casters 20. After being moved to the designated position, the support air cushion 19 inside the retraction seat 18 is activated to achieve support and fixation with the ground. When the bearing arc cover 13 and the moving frame 14 are moved between the first mounting seat 1 and the second mounting seat 2, the air pump 24 on the back of the diversion pipe 23 can be started to inflate the top airbag 25 inside the retraction groove 42 of the support base 3. The top block 26 at one end of the top airbag 25 can fix both ends of the moving frame 14, thereby quickly completing the loading and fixing operation of the bearing arc cover 13 and the moving frame 14, avoiding abnormal loosening problems during subsequent heat treatment flange forging spray cooling. At the same time, the two sets of liquid storage tanks 8 can be inserted and installed into the sleeve covers 7 at both ends of the first mounting seat 1 and the second mounting seat 2 respectively.The liquid storage tank 8 is screwed and positioned onto the first connecting thread 36 on the inner wall of the sleeve groove 35 via a second connecting thread 38 on one side. One end of the tank 8 has a plug connector 40 that directly connects to the plug valve port 34 of the plug groove 33 at one end of the liquid control pump 6. The first sealing ring 37 and the second sealing ring 39 are aligned to ensure a tight connection between the sleeve cover 7 and the liquid storage tank 8. This design allows for rapid replacement and recovery of the cooling water inside the liquid storage tank 8. The above describes the entire working principle of this invention.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
