Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation centrifuges, in particular to a horizontal spiral discharge sedimentation centrifuge for fly ash treatment. Background Art

[0002] The working principle of a horizontal spiral discharge sedimentation centrifuge is that a liquid or suspension containing fly ash enters the centrifugal cavity of the device, and then the fly ash particles settle in the liquid under the centrifugal force generated by the high-speed rotating centrifuge rotor. The settled fly ash particles are discharged from the bottom of the device through a spiral discharge device, while the clean liquid is discharged from the top of the device. For example, the utility model patent with the publication number CN204320467U discloses a horizontal spiral discharge sedimentation centrifuge for mines, including a housing. A drum is arranged inside the housing, and a feeding screw is concentrically arranged inside the drum. The drum and the feeding screw are respectively connected to a differential. The inner cylinder of the feeding screw is connected with a feeding pipe. The drum includes a straight section and a conical section connected to each other. A clarified liquid pipe is arranged at the end of the straight section, and a sediment pipe is arranged at the small end of the conical section. This horizontal spiral discharge sedimentation centrifuge for mines mainly solves the problems of environmental pollution and resource waste caused by the direct discharge of existing mine flushing liquid. It can perform solid-liquid separation and particle size classification on a suspension with a solid phase (particle size 0.005 - 2 mm) concentration of 2% - 40%, realizing the recycling of resources and avoiding environmental pollution. However, when the existing horizontal spiral discharge sedimentation centrifuge is in use, due to the uncontrolled dryness and wetness of the material, the material sometimes agglomerates, which may cause the blockage of the feeding pipe. Therefore, improvement is needed. Content of the Utility Model
