[0002] The horizontal spiral centrifuge is a separation device widely used in the industrial field. It uses the density difference between the solid and liquid phases to separate materials under the action of centrifugal force. However, during the operation, due to the rotation of the inner and outer cylinders, leakage may occur at their joints, especially leakage of the liquid phase, which may not only lead to a decrease in production efficiency, but also cause environmental pollution. The anti-leakage device includes structures such as an outer cylinder, an inner cylinder and a spiral auger. When working, the inner wall of the outer cylinder is fixedly connected with a solid phase protective cover and an isolation ring that are movably sleeved on the outside of the inner cylinder. A first sealing bearing is provided between the outer left side of the inner cylinder and the outer cylinder, and a second sealing bearing is provided between the outer right side of the spiral auger and the outer cylinder.
