Embodiment Construction

[0081] Because the rotor is light, the centrifuge of the present invention has separate, horizontal, and inclined-horizontal structures.

[0082] figure 1 As shown, it is a vertical upward-feeding pulp two-phase separation internal rotor settling centrifuge designed according to the technical solution of the present invention. The centrifuge is composed of a transmission device 3, a pin wheel 5 rotor, a transmission positioning assembly 4, a centrifugal cavity assembly 7, a shell assembly 6, a slurry filter 8, an aerator 9 and a discharge assembly.

[0083] Needle wheel 5 is that U-shaped needle seedlings are radially evenly densely arranged and hung on the ring sheet, and the ring sheet of the needle seedlings plus the spacer ring are layered and stacked and combined on the wheel hub through the key plate and the elastic retaining ring. There are two pin wheels 5 connected in series on the power transmission shaft with a certain interval. The overall profile of the pin whee...

Abstract

The invention discloses an internal rotor sedimentation centrifuge and belongs to the technical field of centrifugal separation of mixed liquids. Existing centrifuge technology suffers from wear and poor ability to separate fine particles or phases with small phase differences. The centrifuge has 5 rotors of light-duty inner-rotating needle wheel, a stator centrifugal cavity that can be covered with filter material, a slurry filter 8, a light phase skimmer 20, and the like. The centrifuge cavity has various forms such as cylindrical shape, conical shape, double-cone parallel shape, double-cone ridge butt joint shape, etc. There are various combinations of slurry inlet and outlet and discharge structures. This technology adopts comprehensive measures such as hydraulic pre-separation and unloading, uniform circumferential slurry feeding, strong centrifugal swirling effect, strengthening the axial symmetry of the centrifugal cavity, uniform circumferential slurry discharge, weakening turbulent flow generation conditions, and stable stratification. The wear resistance is improved, and the separation performance under the same separation factor is significantly improved, and the three-phase separation can be achieved at the same time, while maintaining superior economy. The invention is used in chemical industry and sewage treatment.

Description

1. Technical field [0001] The invention belongs to the technical field of separation of solid suspended particles and liquid, liquid and liquid, solid particles and liquid and liquid of chemical mixed liquid, and relates to the improvement of a settling centrifuge and mass transfer reaction technology. 2. Background technology [0002] Chinese Patent Gazette "Water Treatment Centrifugal Method and Device" (Application No. 98102010.0) discloses a centrifuge technology. This technology uses a needle wheel instead of a drum as the rotor, which has a simple structure and superior economy, but the effect of separating fine particles or mixed liquids with small phase density differences is not ideal. 3. Contents of the invention [0003] Technical problem to be solved: [0004] There are three technical problems to be solved. [0005] First of all, it is to solve the problem of wear and tear on the equipment caused by the particles generated by the accelerated rotation of the ...
