Description

Technical Field

[0001] The utility model relates to the technical field of metal processing devices, in particular to a pit-type annealing furnace for processing non-ferrous metal copper. Background Art

[0002] Annealing is a crucial step in the processing of non-ferrous copper. Annealing furnaces, as key equipment, are used to heat copper to modify its physical properties, improving its plasticity and toughness. Pit-type annealing furnaces, due to their unique structural design, are widely used in non-ferrous copper processing.

[0003] Traditional non-ferrous copper annealing furnaces often lack convenient unloading devices in their structural design. This often requires tedious manual handling and lowering operations, which is not only labor-intensive but also inefficient and can easily pose safety risks to operators.

[0004] During the heating process, traditional annealing furnaces suffer from uneven temperature distribution across the furnace due to limitations in their heating methods and structure. This results in inconsistent heating levels across different copper parts during the annealing process, impacting the annealing quality. Uneven temperatures can also cause variations in copper properties, preventing ideal annealing results and hindering subsequent processing and use. Utility Model Content

[0033] The operating principle of the present invention's pit-type annealing furnace for nonferrous copper processing is as follows: a heating assembly 3 heats the interior of the furnace body 1. A temperature sensor monitors the temperature within the furnace body 1 in real time and transmits the temperature signal to a PLC controller 13. The PLC controller 13 regulates the heating assembly 3 according to the set temperature to achieve precise temperature control. A circulating fan 6 continuously circulates the hot air within the furnace body 1, ensuring uniform temperature throughout the interior of the furnace body 1. A motor 10 rotates the rotating shaft 4 via a driving gear 11 and a driven gear 12, thereby uniformly heating the nonferrous copper parts in the storage basket 5. An exhaust valve 14 regulates the internal pressure of the furnace body 1, ensuring a safe and stable annealing process.

[0034] The use process of the utility model of the pit annealing furnace for nonferrous metal copper processing is as follows:

[0035] 1. Preparation stage: Check whether all parts of the annealing furnace are normal, and ensure that the heating component 3, temperature sensor, PLC controller 13, circulation fan 6, motor 10 and other equipment are in good condition.

[0036] 2. Unloading stage: Start the electric push rod 9 to push the gantry 8 up, thereby driving the furnace cover 2 to rise. Place the non-ferrous metal copper parts that need to be annealed in the storage basket 5.

[0037] 3. Close the furnace cover: After the material is placed, start the electric push rod 9 again to lower the gantry 8, and the furnace cover 2 is covered on the furnace body 1 to ensure a good seal.

[0038] 4. Start the annealing process: After setting the annealing temperature and other parameters via the PLC controller 13, the heating assembly 3 is activated to begin heating. Simultaneously, the circulating fan 6 and motor 10 also begin operating. The circulating fan 6 circulates the hot air within the furnace 1, ensuring a uniform temperature. The motor 10 drives the rotating shaft 4 to rotate, ensuring uniform heating of the copper parts in the storage basket 5.

[0039] 5. Monitoring the Annealing Process: During the annealing process, a temperature sensor monitors the temperature inside furnace body 1 in real time and transmits the temperature signal to PLC controller 13. Based on the temperature signal, PLC controller 13 regulates heating element 3 to ensure that the temperature remains within the set range. Simultaneously, it operates exhaust valve 14 to prevent excessive pressure inside furnace body 1.

[0040] 6. Annealing is completed: When the set annealing time is reached, turn off the heating component 3, the circulating fan 6 and the motor 10. After the temperature in the furnace body 1 drops to a safe range, start the electric push rod 9 again, raise the furnace cover 2, and take out the annealed non-ferrous metal copper parts.
