Description

Technical Field

[0001] The utility model relates to the technical field of spiral discharge ports, in particular to a spiral large discharge port structure for a scale turbid water treatment centrifuge. Background Art

[0002] The horizontal screw centrifuge is a horizontal spiral unloading, continuously operated sedimentation equipment. Its working principle is that the drum and the screw pusher rotate at high speed in the same direction with a certain speed difference. The material is continuously introduced into the feeding bin of the screw pusher through the feed pipe, and enters the drum after acceleration. Under the action of centrifugal force, the heavier solids are deposited on the drum wall to form a sediment layer. The screw pusher continuously pushes the deposited solid phase to the cone end of the drum and pushes it out of the machine through the slag outlet.

[0003] To reduce the amount of wastewater produced by continuous casting and rolling of steel mills, it is necessary to reduce the moisture content of the discharged mud. The solid concentration of the wastewater will cause the screw pusher to be easily blocked, and the material will continuously enter the feed bin of the screw pusher from the feed pipe, enter the drum after acceleration, and be stratified through the centrifuge. When separating some materials that are easy to accumulate, easy to bridge, and sticky fibers, they will accumulate and clog in the feed cone and feed bin. After the feed bin is accumulated, the dynamic balance will be unbalanced, causing large vibration of the whole machine, excessive operating noise, and reduced life of the whole machine.
