Description

Mixing and clearing unit

The utility model is a kind of mixing and separator, is a kind of mixer-settler extractor, is specially adapted to liquid-liquid extraction.

General Box Mixer-settler all is made of mixing chamber and clarifying chamber.Water and organic facies (hereinafter to be referred as two-phase) enter from the mixing chamber bottom simultaneously, mix overflowing to the clarifying chamber by the mixing chamber top; Or two-phase enters by mixing chamber top and bottom respectively, mixes by entering the clarifying chamber in the middle part of the mixing chamber.Such mixer-settler extractor, its mixing chamber generally all are provided with cup, and the effective rate of utilization that this not only cleans difficulty and has reduced mixing chamber simultaneously, also needs bigger stirring and pumping power and vertical mixing intensity and could stablize the clarification interface and reduce line to line fault.

Task of the present utility model is to provide a kind of simple in structure, stable, easy to operate, the few and adaptable liquid-liquid extractor of solvent loss.

The basic principle of the utility model institute foundation is that the centrifugal force that relies on formed motive force of two-phase difference in specific gravity and stirring blade to produce forces two-phase to do reverse flow in mixer-settler extractor.

Characteristics of the present utility model are, mixing chamber does not have cup, and no independent mixing exports mutually, and two-phase all is reverse flow in mixing chamber, clarifying chamber and whole extractor, and the latter end clarifying chamber specializes in the usefulness that is separated.Implementing critical component of the present utility model is by specification requirement oil baffle, water fender and dividing plate to be set in clarifying chambers at different levels.

Below in conjunction with accompanying drawing the utility model is further described:

Accompanying drawing is stereochemical structure and the critical component schematic diagram that mixes a clarifier; ［ 1 ］ is the clarifying chamber among the figure, and ［ 2 ］ are oil baffles, and ［ 3 ］ are water fenders, and ［ 4 ］ are dividing plates, and ［ 5 ］ are Xia Xiangkou, and ［ 6 ］ are mixing chambers, and ［ 7 ］ are Shang Xiangkou, and ［ 8 ］ are flow-stopping plates.

The utility model constitutes a mixed cell by a mixing chamber ［ 6 ］ and a clarifying chamber ［ 1 ］, and mixing chamber ［ 6 ］ is established mouthful ［ 7 ］ and following mouthful ［ 5 ］ mutually mutually.The clarifying chamber that links to each other with first section mixing chamber is the clarifying chamber of load organic phases, and each mixing chamber is at the corresponding levels with adjacent clarifying chamber's (being communicated with by Shang Xiangkou ［ 7 ］) formation.Four limits of mixing chamber ［ 6 ］ equate that its effective depth (Shang Xiangkou ［ 7 ］ lower edge) is 0.8-1.2/1 with the mixing chamber side ratio.Clarifying chamber ［ 1 ］ is 2.5-5/1 with the side ratio of mixing chamber ［ 6 ］.Each clarifying chamber is provided with each one on oil baffle ［ 2 ］, water fender ［ 3 ］ and dividing plate ［ 4 ］.Oil baffle ［ 2 ］ is used for preventing organic facies flow between organic facies back-mixing and controlled stage, this plate is mouth of Ge Kai up and down, lower ports ［ 2b ］ only allows water to pass through, its height (h) is the 80-90% of water fender ［ 3 ］ height, width equates with clarifying chamber ［ 1 ］ width or is slightly less than it, upper port ［ 2a ］ is for logical organic facies or mix usefulness mutually, and its height (H) is the 120-130% of mixing chamber ［ 6 ］ effective depth.

Water fender ［ 3 ］ is used for controlling clarifying chamber's interfacial level, avoids the mixing disturbance of middle part settling section relatively by Xia Xiangkou ［ 5 ］ discharge, increases the bottom mass transfer of this settling section.The height of this plate is 1/3 to 1/2 of a mixing chamber effective depth, and its width equates with the mixing chamber length of side.

Dividing plate ［ 4 ］ constitutes a side of mixing chamber ［ 6 ］, open a mouth in its bottom, i.e. down mutually mouthful ［ 5 ］, for water inlet mutually and go out mixing and use mutually, the following width of mouthful ［ 5 ］ mutually is the 80-90% of mixing chamber ［ 6 ］ length of side, and it highly is the 5-15% of mixing chamber ［ 6 ］ effective depth.

Distance between dividing plate ［ 4 ］ and the oil baffle ［ 2 ］ is the 50-100% of mixing chamber ［ 6 ］ length of side.Water fender ［ 3 ］ is located between oil baffle ［ 2 ］ and the dividing plate ［ 4 ］, and its position is the 25-75% from dividing plate ［ 4 ］ to oil baffle ［ 2 ］ distance.

Open on the partition wall of mixing chamber ［ 6 ］ last mouthful ［ 7 ］ mutually, and it is used for supplying organic facies and going out to mix mutually, and its width is the 30-60% of mixing chamber ［ 6 ］ length of side.

The disturbance of settling section in the middle part of the mixing relatively that flow-stopping plate ［ 8 ］ is used to prevent to be discharged by Shang Xiangkou ［ 7 ］.

Can starch with four leaves are flat with the agitating device that the utility model matches, also the stirring arm of available other form adopts the low-power stirring to meet the demands.

The utility model can form a whole multistage mixing one clarifier unit as required.If progression is too much, as nearly tens grades, hundreds of grades the time, so long mix a clarification unit to several and be processed into an assembly, carry out many combined serial.For increasing clarifying effect, in the end one-level adds a clarifying chamber.All the other are identical with the conventional mixing of design one clarifier.Be used to implement material of the present utility model and can be poly (methyl methacrylate) plate, plastic plate, various metallic plates, this is decided by scale and the extraction system used.

During operation, the direction that the trend of organic facies is pressed dotted arrow indication among the figure flows, and the direction that water is pressed the solid arrow indication flows.After extraction stoste (water) is added by clarifying chamber ［ 1 ］, by oil baffle ［ 2 ］, water fender ［ 3 ］, enter first order mixing chamber from following mouthful ［ 5 ］ mutually, and fully mix with the organic facies that Shang Xiangkou ［ 7 ］ from mixing chamber ［ 6 ］ overflows into, mix mutually respectively continuously from down mutually mouthful ［ 5 ］ discharge with last mouth mutually ［ 7 ］.After the mixing that enters first order clarifying chamber from last phase mouth ［ 7 ］ was passed through phase-splitting mutually, water entered second level mixing chamber continuously.From mixing phase-splitting between oil baffle ［ 2 ］ and dividing plate ［ 4 ］ of mouthful ［ 5 ］ discharge mutually down, water returns mixing chamber, and organic facies enters clarifying chamber's the last period through the upper port of oil baffle ［ 2 ］.Other are at different levels, and the rest may be inferred.Like this, two-phase just forms the trend of an adverse current in mixing a clarifier.

The utility model is compared with general box mixing one clarifier, have simple in structure, stable, easy to operate, the advantage such as solvent loss is few. It does not need inter-stage control, only need keep two-phase and import and export stability of flow, gets final product normal operating. During parking, two-phase is tandem not, does not flow backwards, and not only can produce continuously but also can be interrupted production. Two-phase of the present utility model is mixed the employing slow-speed of revolution and is stirred, and not only energy consumption is low, has avoided again owing to drop is crossed be separated difficulty and the high shortcoming of solvent entrainment loss that pulverizing causes.

The utility model can be used for the extract and separate of the industries such as non-ferrous metal, heavy metal, noble metal, rare earth, antibiotic, is specially adapted to easy emulsification, the extraction system that progression is many.
