Abstract
Disclosed is the improved spiral discharge port structure of a horizontal spiral centrifugal machine, comprising three discharge ports and the changeable protective cover sheets of the discharge ports. The three discharge ports are arranged on the spiral cavity of the horizontal spiral centrifugal machine, and the changeable protective cover sheets of the discharge ports are arranged on the discharge ports. Every protective cover sheet whose inner wall is provided with a wear resistant layer is matched with every discharge port. Cone-shaped accelerating buckets are arranged among the discharge ports for accelerating the flow speed of material on the discharge ports. In the utility model, because more than two discharge ports are arranged on the spiral cavity of the horizontal spiral centrifugal machine, and the accelerating buckets are arranged among the discharge ports, the fluidity of the material is improved, and the wear of the discharge ports caused by the material is dispersed. Simultaneously, the discharge ports are provided with the protective cover sheets which can be detached and changed for preventing the material directly wearing the spiral discharge ports. In addition, the inner sides of the center parts of the protective cover sheets are provided with wear resistant layers for staying the wear of the protective cover sheets caused by the material. The surface of the inner side of the spiral cavity is provided with a wear resistant layer for staying the wear of a spiral caused by the material.
