DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

[0032] like Figures 1 to 4As shown, the intelligent monitoring smelting furnace in this embodiment is suitable for the smelting process of non-ferrous metals such as aluminum, copper, zinc, etc. The design of this equipment is to achieve full automation control of the smelting process, precise adjustment of temperature and atmosphere, and ensure the efficiency and safety of the smelting process.

[0033] 1. Smelting furnace structure design

[0034] 1.1 Shell 1

[0035] The housing 1 is made of high-temperature resistant material with good corrosion and oxidation resistance. A smelting furnace 3 is mounted inside the housing 1 via multiple fixing brackets 104. A sealing cover 2 is provided at the upper end of the housing 1 to seal the smelting chamber and maintain the sealing and temperature stability of the furnace.

[0036] 1.2 Sealing cover 2

[0037] A sealing cover 2 is mounted on the upper end of the housing 1 to ensure that the smelting furnace 3 remains sealed during operation, preventing leakage of high-temperature gases and smoke. A charging cap 201 is provided on the sealing cover 2, which can be opened to add materials during the smelting process. The design of the charging cap 201 ensures operational safety and allows for the rapid addition of smelting materials without affecting the sealing condition of the smelting process.

[0038] 1.3 Heating device 4

[0039] The heating device 4 utilizes an electric heating structure. Multiple heating devices 4 are arranged in a ring inside the housing 1, providing uniform heating for the smelting furnace 3. Each heating device 4 operates independently and is connected via a temperature control module 5. This module collects real-time temperature data within the smelting furnace 3, ensuring precise and stable temperature control at different locations. The heating devices 4 can be configured to perform regional heating according to the requirements of different smelting processes, ensuring uniform heating.

[0040] 2. Intelligent control system

[0041] 2.1 Temperature Control Module 5

[0042] The temperature control module 5 is responsible for precisely regulating the operation of the heating device 4. This module, connected to the temperature monitoring module 8, automatically adjusts the heating power based on real-time temperature data collected from the smelting furnace 3. The temperature monitoring module 8 is mounted on the charging cover 201 and directly measures the temperature within the smelting furnace 3 through the charging cover 201, providing feedback signals to the temperature control module 5.

[0043] 2.2 Liquid level sensor 6

[0044] Liquid level sensor 6, installed at the center of smelting furnace 3, monitors the level of the liquid metal in real time. During the smelting process, liquid level sensor 6 detects the melting state of the metal and the liquid level, and issues an alarm when the liquid level reaches a preset upper or lower limit. This sensor ensures the safety of the smelting process and prevents over-smelting or insufficient liquid level.

[0045] 2.3 Pressure monitoring module 7

[0046] The pressure monitoring module 7 is located above the smelting furnace 3 and is used to monitor the pressure changes of the gas in the smelting furnace 3 in real time. When high-temperature gas or abnormal air pressure is generated during the smelting process, the pressure monitoring module 7 can promptly feedback data to the temperature control module 5 and activate the automatic exhaust system to adjust the atmosphere in the smelting furnace 3 through the air inlet 102 and exhaust port 103 at the bottom of the housing 1.

[0047] 3. External support and tilting operation

[0048] 3.1 External support mechanism 9

[0049] The external support mechanism 9 comprises multiple brackets 101, a rotating shaft 901 mounted on the brackets 101, and a motor 902. The rotating shaft 901 is mounted on top of the brackets 101, and the motor 902 is connected to the rotating shaft 901. The motor 902 drives the rotating shaft 901 to rotate, thereby tilting the smelting furnace 3. This tilting operation is used to discharge the molten metal after smelting. This design simplifies the molten metal discharge process, making it more efficient and accurate.

[0050] 4. Workflow

[0051] 4.1 Preparation

[0052] Before smelting begins, the operator first adds smelting raw materials (such as aluminum, copper, etc.) to the smelting furnace 3 through the charging cover 201 on the sealing cover 2. After the charging is completed, the sealing cover 2 is completely closed to ensure a tight seal in the smelting environment. Based on the set smelting process parameters, the system activates the heating device 4 to begin heating the raw materials in the smelting furnace 3.

[0053] 4.2 Automated smelting process

[0054] During the heating process, the temperature control module 5 monitors the temperature within the smelting furnace 3 in real time via the temperature monitoring module 8, ensuring uniform heating and temperature stability. The liquid level sensor 6 monitors the height of the molten metal to ensure it remains within a safe range. Simultaneously, the pressure monitoring module 7 monitors the gas pressure within the smelting furnace 3. If the gas pressure is too high, the system adjusts the atmosphere through the air inlet 102 and exhaust port 103 to ensure a stable smelting environment.

[0055] 4.3 Liquid metal discharge

[0056] After smelting is complete, the system uses motor 902 to drive shaft 901, achieving tilting of smelting furnace 3. The molten metal automatically flows out through discharge port 301 and into a designated container. Liquid level sensor 6 monitors the discharge process in real time to ensure accurate discharge.

[0057] 4.4 System Maintenance

[0058] After each smelting operation, the heating device 4 can be easily inspected and replaced due to its detachable structure, ensuring long-term stable operation of the equipment. The ventilation area 202 between the housing 1 and the smelting furnace 3 can also effectively regulate the airflow during the smelting process, preventing the furnace atmosphere from being too closed, and ensuring the efficiency and stability of the smelting process.

[0059] 5. Equipment advantages

[0060] Intelligent monitoring: Through real-time data collection and feedback from the temperature control module 5, liquid level sensor 6, pressure monitoring module 7, etc., the fully automatic control of the smelting process is achieved.

[0061] Efficient heating: Multiple independently operated heating devices 4 ensure uniform temperature distribution inside the smelting furnace 3, which is suitable for the requirements of different smelting processes.

[0062] Automatic discharge: The electric tilting system of the rotating shaft 901 is driven by the motor 902 to achieve rapid discharge of the molten metal after smelting, thereby improving operation efficiency.

[0063] High safety: Multiple monitoring modules and atmosphere adjustment systems ensure the safety and stability of the smelting process.

[0064] In summary, this embodiment provides an intelligent non-ferrous metal smelting furnace that can efficiently and stably complete the entire process of metal smelting and ensure the safety and accuracy of smelting through an intelligent monitoring system.
