However, because powdered materials are prone to containing impurities, they can easily cause blockages in pipes and equipment during the addition process. Existing powdered material adding equipment often requires manual operation and unblocking, resulting in high labor intensity for workers and posing safety and environmental risks. Furthermore, manual operation makes it difficult to accurately control the amount of material added, easily leading to inaccurate proportions and wasted resources. Summary of the Invention

The switching valve and the metal detection device are sequentially arranged on the first conveying pipe between the material source and the powdered material metal removal device. The powdered material metal removal device includes a shell, a partition, a first valve, and a second valve. Two valves, a first electromagnet, and a second electromagnet are present. A partition divides the inner cavity of the housing into a first cavity and a second cavity. The first valve and the second valve are connected to the partition. The first electromagnet is disposed in the first cavity, and the second electromagnet is disposed in the second cavity. When the first valve and the second valve are open, the first conveying pipe is connected to the first cavity. When the first valve and the second valve are closed, the first conveying pipe is connected to the second cavity. Initially, the first valve and the second valve are open. The control unit includes a main controller, a metal detection device controller, and a powdered material metal removal device controller. The level gauge is connected to the main controller, and the metal detection device controller... The controller connects the metal detection device and the main controller. The powdered material metal removal device controller connects the powdered material metal removal device and the main controller. When the level gauge detects a low material level in the material storage device, it transmits the low material level information to the main controller, opening the switching valve and allowing the material source to enter the first conveying pipe. When the metal detection device detects metal impurities in the material in the first conveying pipe, it sends a signal to the metal detection device controller. The metal detection device controller then sends a signal to the main controller, which in turn sends a signal to the powdered material metal removal device controller. The powdered material metal removal device controller controls the first electromagnet to operate. When the metal detection... After the detection device sends a preset number of signals to the metal detection device controller, the metal detection device controller sends a signal to the main controller. The main controller then controls the first valve and the second valve to close. The first valve and the second valve transmit their closing signals to the main controller. The main controller then sends a signal to the powdered material metal removal device controller, which controls the first electromagnet to stop working. The first electromagnet transmits its stoppage information to the powdered material metal removal device controller, which in turn transmits this information to the main controller. Finally, the main controller controls the second electromagnet to operate.After the metal detection device sends a preset number of signals to the metal detection device controller, the main controller controls the first valve and the second valve to open, and the first electromagnet to operate.
