Liquid skimming device in settling and filtering type centrifuge

Abstract

The invention discloses a liquid skimming device in a settling and filtering type centrifuge which can suck liquid phase, comprising a bottom plate arranged on a shell, wherein a bearing seat is arranged on the bottom plate, a bearing cavity is arranged in the bearing seat, a bearing is arranged in the bearing cavity, the bearing seat is provided with a pressing cover at the outer side of the bearing, an adjusting nut is arranged in the bearing, an axial through hole which penetrates through the bearing seat is arranged at the bottom of the bearing cavity, the adjusting nut extends out of the pressing cover and is fixed with an adjusting handle wheel, a hollow screw rod which is arranged inthe axial through hole in a penetrating way is in threaded connection with the adjusting nut, axial key grooves which are mutually matched are respectively arranged on the inner wall of the axial through hole and the outer wall of the hollow screw rod, guide keys are arranged in the axial key grooves, and a liquid skimming pipe which is communicated with the hollow screw rod is connected to the tail part of the hollow screw rod. The invention broadens the application range of the settling and filtering type centrifuge.

Description

Technical field [0001] The invention relates to a sedimentation and filtration centrifuge, and particularly relates to a liquid skimming device in a sedimentation and filtration centrifuge. Background technique [0002] As we all know, centrifugal filtration is a process of solid-liquid separation of suspended material liquid by centrifugal force. Both sedimentation and filtration centrifuges belong to the separation machinery of fixed-layer filter cake centrifugal filtration. Although these centrifuges have different structures and operating methods, their working processes are basically the same, usually consisting of feeding, settling, filtering, washing and drying stages. The specific process is as follows: After the centrifuge is started, the material liquid is added to the rotating drum. Under the action of centrifugal force, the solid particles in the material liquid are trapped on the filter medium, and continue to accumulate into a filter cake layer. At the same time, th...

Problems solved by technology

However, in the actual use process, when encountering some materials with special physical properties such as particularly fine and high viscosity, it is difficult to separate the solid and liquid phases.

This restricts the application range of sedimentation and filter centrifuges
