Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, and more particularly to an automatic feeding system used in a smelting process. Background Art

[0002] In the metal smelting industry, an accurate, uniform, and stable supply of raw materials is crucial for ensuring a smooth smelting process and high-quality smelted products. Traditional methods of feeding raw materials typically rely on manual operation or simple mechanical feeding devices. This approach is not only inefficient and prone to errors, but also prone to uneven or untimely feeding, which can affect the stability of the smelting process and even lead to quality issues in the smelted products. Especially during the smelting process, where furnace temperatures are extremely high, frequent manual operation poses safety risks, seriously threatening the health and safety of operators.

[0003] With the continuous development of automation technology, automated feeding systems have been introduced in many industries. However, their application in the metallurgical industry is still relatively rare. Existing automatic feeding equipment often uses mechanical control and simple timed feeding methods. This method often cannot flexibly adjust the feeding amount according to changes in the smelting process, resulting in unstable or inaccurate feeding. In addition, the maintenance and cleaning of traditional equipment are also relatively complicated, resulting in low equipment efficiency and high failure rate, further affecting the continuity and stability of the smelting process.

[0004] In practical applications, the smelting process requires a wide variety of raw materials, each with stringent requirements for feed quantity, frequency, and accuracy. Traditional mechanical feeding methods struggle to meet these diverse demands, especially when the smelting process is complex and temperature control is critical. Precise control of feed quantity is crucial.

[0005] Therefore, how to design a system that can automatically adjust the raw material delivery and feeding amount according to the actual process requirements becomes the key to improving the quality of the smelting process. Utility Model Content

The rotating arms arranged in the same direction are rotatably connected by a fixed rod, and the fixed rod is fixedly connected to the discharge port for controlling the opening and closing of the discharge port.

[0011] Preferably, the cylinder is controlled by a control system and can drive the rotating arm to drive the fixed rod to rotate, thereby controlling the opening and closing of the discharge port and adjusting the discharge amount.

[0012] Preferably, the spiral conveying blade is driven by a motor and a reducer to evenly convey the raw materials in the silo to the lower hopper, and the rotation speed of the spiral conveying blade can be adjusted according to the feeding requirements of the smelting process.

[0029] Example

[0030] An automatic feeding system for a smelting process, such as Figures 1 to 3 Shown, including:

[0031] Silo 1: Stores raw materials needed for smelting. A discharge port is located at the bottom of silo 1, and raw materials are transported to the smelting furnace via conveyor channel 2. The silo's large design capacity can meet the continuous demand for raw materials during the smelting process, reducing the frequency of manual feeding.

[0032] Conveying device: The conveying device primarily comprises a conveying channel 2, a spiral conveyor blade 204, a motor 202, and a reducer 203. The spiral conveyor blade 204 is installed within the conveying channel 2 and, driven by the motor 202 and reducer 203, evenly conveys the raw materials from the silo to the lower hopper 3. A maintenance cover 201 is located at the end of the conveying channel away from the silo to allow for maintenance and cleaning of the spiral conveyor blade.

[0033] Weighing and Discharging Mechanism: The hopper 3 is mounted at the lower end of the conveyor channel, near the maintenance cover 201, via a mounting bracket 302. A pair of discharge ports 306 are located at the lower end of the hopper 3, each connected to a weighing plate 307. The weighing plates 307 measure the weight of the material passing through the ports and provide feedback to the control system. A mounting bracket 301 is mounted at the upper end of the hopper, with rotating arms 303 mounted on either side. Cylinders 304 drive the rotating arms to open and close the discharge ports, thereby adjusting the discharge volume.

[0034] Control system: The control system includes a PLC controller that monitors the temperature, raw material consumption, liquid level, and other information within the smelting furnace. Based on sensor feedback, the control system adjusts the speed of the spiral conveyor blades and the opening and closing frequency of the feed port in real time to ensure accurate and stable raw material feeding.

[0035] Preferred embodiments

[0036] Automatic feeding control: The control system adjusts the speed of motor 202 to control the operation of the spiral conveyor blade 204 according to the real-time process requirements within the smelting furnace, ensuring a uniform and continuous supply of raw materials. When the weighing plate 307 detects the required feeding amount, the system controls the opening and closing of the discharge port 306 to ensure accurate feeding.

[0037] Weighing plate's precise monitoring function: The weighing plate 307 monitors the weight of raw materials passing through the feed port in real time and feeds this data back to the control system. The system automatically adjusts the feeding speed and frequency based on the weighing data, ensuring accurate feeding each time and preventing over- or underfeeding.

[0038] Repair and Maintenance: The conveying channel 2 is equipped with a maintenance cover 201 for easy maintenance and inspection of components such as the spiral conveying blade 204 and the motor 202. The lower hopper 3 and the conveying channel are designed to be simple and easy to disassemble and clean, ensuring long-term stable operation of the equipment.
