Description

Technical Field

[0002] An aging furnace for cast iron is an industrial heating device used for aging treatment of cast iron parts. By controlling the temperature and holding time, it eliminates internal stress in the castings, stabilizes dimensions, and improves mechanical properties. It is applied in machinery manufacturing to reduce deformation during subsequent processing and improve the precision and stability of cast iron parts.

[0003] The cooling system of the aging furnace for cast iron is used to control the temperature inside the furnace and prevent overheating from damaging the equipment and workpieces. Aging treatment requires precise temperature control. When rapid cooling is needed after heating, the cooling system uses a cooling medium to remove excess heat, ensuring the temperature remains stable within the process range. This protects the furnace's refractory materials and heating elements, extends equipment life, and guarantees the aging effect.

Specifically, when the cooling mechanism 3 is working, multiple branch pipes 31 at the bottom of the main pipe 2 are connected to the connecting seat 3112 through the flange 3111 of the connecting assembly 311. The bolts 3121 of the fixing assembly 312 pass through the flange 3111 and are threadedly connected to the nut 3122, so as to achieve a sealed connection between the branch pipes 31 and the top of the ball valve 33.

The branch pipes 32 at the bottom of the front and rear sides of the furnace body 1 control the flow through the ball valve 33 at the top. The opening degree of the ball valve 33 is adjusted by turning the wrench 34. The medium flow is regulated by the solenoid valve 35 and the manual valve 36 on the right side. The fan 37 provides the air source. The cooling intensity is controlled by the cooperation of the ball valve 33 and the solenoid valve 35.

Through the cooperation of the support bar 3101 and the fixing frame 3102, the structural stability of the furnace body 1 during the cooling process is enhanced. During the cooling process, the fan 37 sends cold air into the main pipe 2 through the solenoid valve 35 and the manual valve 36, and then into the furnace body 1 through the eight branch pipes 31 and the branch pipes 32 at the bottom of the main pipe 2. The branch pipes 31 and the branch pipes 32 work together to transport the cooling medium, and the ball valve 33 and the fan 37 dynamically adjust the cooling rate to work together to maintain the temperature of the furnace body 1.

[0020] Reference Figure 1 and Figure 5 The exhaust mechanism 4 includes two exhaust seats 41. The bottom of the two exhaust seats 41 is fixedly connected to the top of the furnace body 1. The top of the two exhaust seats 41 is fixedly connected to a butterfly valve 42. The top of the two butterfly valves 42 is fixedly connected to an output pipe 43. The top of the furnace body 1 is fixedly connected to two support frames 44. The top of the two support frames 44 is fixedly connected to an angular stroke actuator 45. Specifically, when the exhaust mechanism 4 is working, the bottom of the two exhaust seats 41 are fixed to the top of the furnace body 1 to provide an installation base for the exhaust outlet. The top butterfly valve 42 controls the opening and closing of the exhaust channel by rotating the valve disc. The output pipe 43 is connected to the top of the butterfly valve 42 to export the gas in the furnace body 1. Through the cooperation of the exhaust seats 41 and the butterfly valve 42, the on and off control of the exhaust channel is realized. Two support frames 44 on the top of the furnace body 1 support the angular stroke actuator 45. The output shaft is connected to the butterfly valve 42. After receiving the control signal, the butterfly valve 42 is driven to rotate to adjust the channel opening. Through the cooperation of the support frame 44 and the angular stroke actuator 45, the butterfly valve 42 is automatically adjusted. When the gas inside the furnace body 1 needs to be discharged, the angular stroke actuator 45 drives the butterfly valve 42 to open. The gas enters the butterfly valve 42 through the exhaust seat 41 and is then discharged outside the furnace through the output pipe 43. Through the linkage between the actuator and the butterfly valve 42, the exhaust process can be precisely controlled. During the exhaust process, the exhaust seat 41 maintains a sealed connection with the furnace body 1 to prevent gas leakage. The support frame 44 firmly supports the actuator to ensure stable transmission of output torque. The angular stroke actuator 45 adjusts the opening of the butterfly valve 42 in real time according to the changes in gas pressure inside the furnace to maintain a stable exhaust rate.

[0021] Working principle: The cooling mechanism 3 is connected and debugged. The top of multiple branch pipes 31 is fixed to the bottom of the main pipe 2. The bottom is connected to the connecting seat 3112 through the flange 3111 of the connecting component 311. The bolt 3121 of the fixing component 312 passes through the flange 3111 and is threadedly connected to the nut 3122 at the bottom, sealing the branch pipes 31 to the top of the ball valve 33 to ensure that the cooling medium transmission channel is stable and sealed. The top of multiple branch pipes 32 at the bottom of the front and rear sides of the furnace body 1 is fixed with ball valves 33. By turning the wrench 34 on the side away from the ball valve 33, the opening degree of the ball valve 33 can be adjusted, thereby controlling the flow rate of cold air. The solenoid valve 35 on the right side of the furnace body 1 works in conjunction with the manual valve 36 at the bottom to further regulate the flow of the cooling medium. The fan 37 on the right side of the manual valve 36 provides the air source. The cold air enters the main pipe 2 through the solenoid valve 35 and the manual valve 36, and then enters the furnace body 1 from the branch pipe 31 at the bottom of the main pipe 2 and the branch pipes 32 at the bottom of the front and rear sides of the furnace body 1. In the mounting assembly 38 on the right side of the furnace body 1, the distribution box 381 is fixed to the right side of the furnace body 1 on the left. In the internal electrical components 39, the touch screen 391 receives the operation... When the inverter 392 is given a command, it adjusts the speed of the fan 37. When the cover 382 on the right side of the distribution box 381 is closed, it protects the internal components. In the support assembly 310 on the front and rear sides of the furnace body 1, multiple V-shaped supports 3101 are fixed to the front and rear sides of the furnace body 1 to distribute the weight of the furnace body 1. The fixing frame 3102 on the side away from the support 3101 and the limiting block 3103 on the top limit the displacement of the furnace body 1 and enhance the structural stability of the furnace body 1 during the cooling process. The exhaust mechanism 4 starts working. The bottom of the two exhaust seats 41 is fixed to the top of the furnace body 1, providing an installation base for the exhaust system. The butterfly valve 42 at the top controls the opening and closing of the exhaust channel by rotating the valve disc. The output pipe 43 at the top of the butterfly valve 42 discharges the gas in the furnace body 1. The two support frames 44 at the top of the furnace body 1 support the angular stroke actuator 45. The output shaft of the angular stroke actuator 45 is connected to the butterfly valve 42. After receiving the control signal, it drives the valve disc of the butterfly valve 42 to rotate, adjusting the opening of the exhaust channel. When the gas in the furnace body 1 needs to be discharged, the angular stroke actuator 45 drives the butterfly valve 42 to open. The gas enters the butterfly valve 42 through the exhaust seat 41 and is discharged outside the furnace through the output pipe 43.
