1 results about "Yellow iron oxide" patented technology

This utility model relates to the field of iron oxide yellow production technology, and discloses a feeding device for producing low-sulfur iron oxide yellow. The device includes a support frame, a weighing mechanism on the inner side of the support frame, a pad at the bottom of the support frame, and multiple support legs fixedly connected to the top left side of the pad. The tops of the multiple support legs are fixedly connected to the same storage tank, and the storage tank has an anti-blocking mechanism inside. The weighing mechanism includes a fulcrum rod, which is fixedly connected to the middle of the inner side of the support frame. A balance rod is rotatably connected to the outer wall of the fulcrum rod. In this utility model, when the weights at both ends of the balance rod are equal, a trigger switch is activated to close the electric valve, and cylinder two is activated, causing the balance rod to rotate 90 degrees. Subsequently, cylinder one is activated to push the moving block to slide, causing the opening and closing plate to move to both sides of the material container, allowing the material inside the container to fall downwards, thus achieving a quantitative feeding process.
