Problems solved by technology

[0005] (1) Since an L-shaped partition is arranged in the diversion body, and the side of the partition is the first heavy phase diversion hole, in addition, the lower side of the partition protrudes inward and is provided with a light phase weir, therefore, the The setting of the separator and the light phase weir is not a centrosymmetric structure. Therefore, in the actual processing, the processing technology is very high to ensure its dynamic balance. Limited by the current processing accuracy, the entire diversion body is designed It is very easy to have a dynamic balance deviation during processing, which will cause the guide body to vibrate during high-speed rotation, and with the increase of the rotational speed, the greater the vibration amplitude, the vibration will seriously affect the stability of the two-phase separation interface in the drum , which leads to the deterioration of the separation effect. In addition, for some materials that are difficult to separate (such as the light phase and the heavy phase, the phase difference is very close, such as the minerals in the salt pond slurry, etc.), the motor must be required to rotate at an ultra-high speed. High centrifugal separation efficiency is achieved, but the vibration caused by high-speed rotation will make the two-phase separation interface very unstable, which will lead to poor separation effect;
[0006] (2) The gland of the centrifugal extractor is integrally designed on the guide body. It is inconvenient to clean the blockage inside the guide body. In addition, because there are many structural parts that cooperate with each other inside the centrifugal extractor, the replacement of the heavy phase weir and other parts The maintenance is very inconvenient and the processing technology is complicated, and the integral design of the gland will make debugging more difficult

Abstract

The invention discloses a centrifugal extractor which comprises a motor, a flow deflector assembly, a rotary drum and a housing, wherein the flow deflector assembly comprises a flow deflector that is a centrosymmetric structural body, a baffle is arranged in the flow deflector and divides the flow deflector into an inlet chamber and an outlet chamber, a plurality of light-phase flow deflection holes distributed in a central symmetry manner through taking a rotation axis of the flow deflector as the center are formed in the baffle, inlet ends of the light phase flow deflection holes are communicated with the neighborhood of the center of the inlet chamber, outlet ends of the light phase flow deflection holes penetrates from the flow deflector and are communicated with a light phase outlet, a plurality of first heavy phase flow deflection holes communicated with the inlet chamber and the outlet chamber are formed in the baffle, and the first heavy phase flow deflection holes are distributed in a central symmetry manner through taking the rotation axis of the flow deflector as the center. The centrifugal extractor has a reasonable structural design, is convenient to process accurately by means of overall dynamic balance, and is good in dynamic balance; the flow deflector is less in vibration during the high-speed operation process, the two-phase separation interface is stably controlled, the extraction and separation effect is good, and meanwhile, the centrifugal extractor is also applicable to high-speed extraction and separation of materials difficult to separate.

Description

Technical field [0001] The invention relates to a centrifugal extractor. Background technique [0002] Centrifugal extractor is a kind of high-efficiency liquid-liquid extraction equipment designed by the principle of extraction and separation, which is widely used in hydrometallurgy, medicine, fine chemicals and other fields. The main structure of a traditional centrifugal extractor includes a motor, a diversion fluid, a rotating drum and a housing. A partition is arranged in the diversion fluid, and a light-phase diversion hole is arranged under the partition. Between the side of the partition and the inner wall of the diversion fluid An axial heavy phase guide hole is formed, a heavy phase weir is arranged above the fluid guide, an axial flow control hole is arranged on the heavy phase weir, and a material inlet, a heavy phase outlet and a light phase outlet are arranged on the shell. For details, please refer to the XS-34 (ring) centrifugal extractor of "Cylinder Centrifugal...
