For example, Chinese patent CN218360692U provides a sieving device for turbine coating material particles, including a screening box, a door hinged to the front surface of the screening box, and support legs fixedly connected to the bottom surface of the screening box near the four corners. The device also includes a sieving assembly inside the screening box, comprising three sets of rectangular mounting blocks fixedly connected to the inner wall of the screening box, a sliding rod fixedly connected to the surface of each rectangular mounting block, and a spring sleeved on the surface of each sliding rod. Each set of rectangular mounting blocks has a filter plate slidably mounted on it via the sliding rod. In such sieving devices, large particles are difficult to remove, and during vibrating screening, they can easily become partially stuck on the filter screen, making removal difficult.
