Abstract
The utility model relates to a multistage countercurrent centrifugal extractor. The multistage countercurrent centrifugal extractor comprises a shell, wherein a motor is arranged at the top of the shell, a light-phase liquid outlet and a heave-phase liquid outlet are formed in the upper end of the shell and are formed in the middle of the outer side of the shell, a light-phase weir plate is arranged on the inner side of the upper part of the shell, a heavy-phase weir plate is arranged at the lower part of the light-phase weir plate, and a boundary surface is arranged at the bottom of the heavy-phase weir plate. The multistage countercurrent centrifugal extractor is characterized in that collection chambers are formed in the lower parts of the light-phase liquid outlet and the heave-phase liquid outlet, wherein a rotor drum is arranged on the outer side of the heavy-phase weir plate at the bottom of the light-phase weir plate, a blade is arranged in the middle of the rotor drum, an impeller is arranged at the bottom of the rotor drum, and a flow baffle disc is arranged at the lower part of the impeller. The multistage countercurrent centrifugal extractor has the advantages that the structure is compact, liquid is gradually separated while flowing in a rotor from bottom to top, a separation region ranges from the flow baffle disc to the light-phase weir plate, the separated liquid-liquid phases are collected to each collection chamber respectively through the light-phase weir plate and the heavy-phase weir plate and are discharged through each outlet, and the heavy-phase weir plate can be detached to be exchanged so as to change the diameter of the weir plate.
Description
Technical field
The utility model relates to industrial equipment technical field, especially relates to a kind of multi-stage countercurrent centrifugal extractor.
Background technology
Centrifugal extractor first fully mixes in centrifugal force field, impel the transfer of solute, then carry out separation and the discharge of two-phase liquid, light phase liquid is from close rotatory drum wall charging, heavy-fluid, mutually from rotary drum central feeding, forms the counter current contacting that two-phase is disperseed in rotary drum.When final two-phase reaches the other end of rotary drum, weight liquid phase is concentrated in respectively rotary drum center and inwall place discharges, but current centrifugal extractor separates with maleic acid for maleic anhydride, and separating effect is not obvious, does not reach separation criterion.
Utility model content
In order to address the above problem, the technical solution adopted in the utility model is as follows:
A kind of multi-stage countercurrent centrifugal extractor, comprise housing, case top is provided with motor, be provided with light phase liquid outlet and heavy-phase liquid outlet in housing upper end, light phase liquid entrance and heavy-phase liquid entrance are arranged in the middle of hull outside, housing upper inner is provided with light phase weir plate, light phase weir plate bottom is heavy phase weir plate, heavy phase weir plate bottom is interface, it is characterized in that: described light phase liquid outlet and heavy-phase liquid outlet bottom are collecting chamber, outside light phase weir plate bottom, heavy phase weir plate, are provided with rotary drum, and rotary drum middle part is provided with blade, bottom of the drum is provided with impeller, and impeller bottom is baffle dish.
Described motor is direct-connection type motor, drives rotary drum High Rotation Speed by direct-connection type motor by shaft coupling, produces needed powerful centrifugal force field, changes motor speed by frequency converter, can change the size of centrifugal force field, to adapt to different systems.
Light phase liquid is contrary with the flow direction of heavy-phase liquid in extracter, good separating effect, and extraction purity is high.
Centrifugal extractor is two, and connected mode is for being connected in series.
Described heavy phase weir plate is disassembled and change the weir plate of different-diameter.
Advantage of the present utility model: drive rotary drum High Rotation Speed by direct-connection type motor by shaft coupling, produce needed powerful centrifugal force field, change motor speed by frequency converter, can change the size of centrifugal force field, to adapt to different systems.In this centrifugal force field, heterogeneous mixed liquor is because of its density difference, and suffered centrifugal force is also different, Gu and produce lamination, thus the object that reaches extraction or separate.
This machine collection mixes and is located away from one, and compact conformation accelerates the separation of liquid-liquid two-phase with difference in specific gravity by centrifugal force, two liquid phases that do not merge enter respectively the exocoel of rotor from two charging mouths of pipe, by the rotation of rotor and rapid mixing, mixed liquid enters internal rotor by the passage of rotor bottom, the internal rotor with self priming pump function is divided into four vertical cavitys, the mutual balance of liquid entering, liquid separates gradually in flow process from below to up in rotor, Disengagement zone is from baffle dish until light phase weir, ensure time enough and form liquid-liquid interface, the liquid-liquid phase of separating is respectively by light, heavy phase weir is pooled to collecting chamber separately, and respectively by exporting separately discharge, heavy phase weir plate can be pulled down and change to change weir plate diameter.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
