Description

Settle extractor

The utility model is that a kind of mixing chamber occupies the bottom, and the clarifying chamber places the liquid-liquid extraction mixer-settler extractor on top.

Mixer-settler extractor is to use liquid-liquid extraction equipment very widely, the horizontal tandem arrangement in the mixing chamber of general horizontal mixer-settler extractor and clarifying chamber.Make the mixer-settler extractor floor space big like this, can not be than the space of good utilisation factory building, flux is little, organic facies, the water hold-up is big, produces substantial contribution and overstocks.Enter light, the heavy phase of mixing chamber, the employing that has enters from the mixing chamber bottom simultaneously, and it needs bigger suction force, and consume additional power is many.Have gently from the top, heavy phase enters mixing chamber from the bottom, mixes from the mixing chamber middle part to flow out, it is short in the mixing chamber time of staying that this method easily produces the part particle, and cause stage efficiency low.The employing that has is from top (Shang Xiangkou) gently, and (Xia Xiangkou) enters mixing chamber to heavy phase from the bottom.Heavy phase through mixing is taken mixing chamber out of by mixing to flow out from last phase mouth, and gently returns mixing chamber from last phase mouth after the phase-splitting, mixed from mouthful flowing out mutually down through gently communicating of mixing and take mixing chamber out of, and the heavy phase after the phase-splitting is returned mixing chamber again.Because light, heavy phase that already hybrid reaction is crossed are returned mixing chamber again again, cause mixing chamber, clarifying chamber's load to increase about 1 times, processing flux will be little like this, and perhaps stage efficiency reduces.Moreover weight boundary fluctuation has considerable influence to the product quality of extract and separate stable in the mixer-settler extractor.Existing mixer-settler extractor does not have fine addressing this problem.

The purpose of this utility model is will provide a kind of can utilize the factory building space, and floor space is little, but not too high again when equipment is large-scale, flux is big, and the stage efficiency height is easy to make, stable, the liquid-liquid extraction mixer-settler extractor that consume additional power is low.

Mixing chamber of the present utility model occupy the bottom of extractor, and the top of extractor is last clarifying chamber, and mixing chamber one side is other to be the Entry Interface district.Improve the horizontal tandem arrangement of mixing chamber and clarifying chamber in the past like this, floor space reduces at double, can utilize the factory building space.The utility model is because the clarifying chamber mainly on extractor top, so can make settling section be the thin layer phase-splitting, can dwindle the volume of clarification so greatly.The pallet that can keep heavy phase is arranged at mixing chamber of the present utility model top, and having realized like this has heavy phase and light interface mutually on extractor top, is beneficial to the clarification that mixes phase.Arrive the Entry Interface district and enter in this district's heavy phase at the heavy phase that this pallet is clarified out the pallet overfall that overflow.Under occasions such as some extraction system or specified conditions, the Entry Interface district of mixing chamber one side also can be used as settling section, carries out clarification mutually to mixing.This moment on pallet also not the mixing of the phase-splitting pallet overfall that also overflow mutually arrive the Entry Interface district and further clarify.Pallet has and mixes the tube outlet of phase garden, or and (one or several) rectangle mix mutually and export.Threaded in mixing phase garden tube exports, make outer movable threaded energy height up and down, rectangle is mixed outlet mutually the big or small portable plate of the outlet can regulated.

Weight of the present utility model is to enter mixing chamber so mutually, and the shaft hypomere is hollow pipe (claiming hollow tubular axis), has several holes (promptly gently portal mutually and heavy phase portal) at the hollow tubular axis in paddle place.Hollow tubular axis has several and gently enters the hole mutually above stirring vane.There is a little socket broad in the middle in two hollow tubular axis outside in this position, as gently sucking mutually every the tube of diving.Rotate when stirring, the suction force of agitator passes to by hollow tubular axis gently enters the hole mutually, is to make the suction force of gently entering the hole mutually can aspirate the light phase that will advance mixing chamber every latent effect.The light suction mutually every the tube of diving is communicated with light passage mutually.The lower ending opening of hollow tubular axis, and place the heavy out pipe.Hollow tubular axis lower ending opening rotates when stirring, in can suck heavy phase and stir.Weight of the present utility model enters mixing chamber mutually like this, needs less suction force, can not reduce stage efficiency simultaneously or reduce flux.Stirring vane shape of the present utility model is trapezoidal greatly, can be by two, and three, four or multi-disc composition agitator.Because agitator is big trapezoid blade, and major diameter is arranged, large tracts of land is so agitator upper and lower suction is less than gently advancing hole, heavy phase import mutually.Can stir under the slow-speed of revolution like this, peptizaiton is evenly distributed, avoid the meticulous phenomenon of drop to produce, power consumption is low.The mass-transfer efficiency height.

The weight boundary of the utility model extractor is control like this, have in the heavy phase channels of settling section upper end and the adjacent level aperture of intercommunication (hole on the phase of the weighing passage) mutually, adjacent level gently is on good terms to flow in the heavy phase channels, because the light boundary height of adjacent level equates, thus in the heavy phase channels light phase liquid level gently liquid level is similar mutually with this level.The heavy phase height in heavy phase height and Entry Interface district is suitable in the heavy phase channels like this, and dividing plate and interface adjustable plate are arranged in the heavy phase channels.When heavy phase was higher than the interface adjustable plate in the Entry Interface district, the heavy phase in the heavy phase channels also was higher than the interface adjustable plate, and the heavy phase interface adjustable plate that can overflow flows to next stage like this.When the adjustable plate of the low interface of heavy phase in the Entry Interface district, heavy phase in the heavy phase channels also is lower than the interface adjustable plate, the heavy phase interface adjustable plate that can not overflow, because next stage has suction force to heavy phase channels, heavy phase height in the dividing plate will descend, light also decline mutually in the heavy phase channels like this, because hole on the heavy phase channels is arranged, adjacent levels gently adds in the heavy phase channels by this hole, make in the heavy phase channels light light highly quite mutually with this level all the time mutually, the heavy phase height in the heavy phase channels can not raise because heavy phase decline in the dividing plate like this.If next stage is too big to heavy phase suction force in the heavy phase channels dividing plate, to cause in the dividing plate heavy phase to suck and further aspirate light phase.Can pass through to change conditions such as stirring in this case, and/or regulate the heavy phase traffic controller and aligned.The utility model carries out like this, and the fluctuation of weight boundary is little, and the heavy phase of inter-stage is steadily flowed uniformly, and stage efficiency is steady, is beneficial to the products of separated steady quality.Reduced the suction force of next stage simultaneously to this grade heavy phase.In like manner also reduce the suction force to the upper level heavy phase at the corresponding levels, thereby reduced power consumption.

The utility model is to realize like this, when being used for the liquid-liquid extraction, after agitator rotates, the suction force of agitator passes to by hollow tubular axis gently enters the hole mutually, since every the existence of the tube of diving make easily light phase on the lenient side the phase passage through entering stirring every the tube of diving, hollow tubular axis, hybrid reaction in mixing chamber, heavy phase is under the suction force effect of agitator, from heavy phase channels, enter through heavy phase inlet tube, hollow tubular axis and to be stirred in hybrid reaction in the mixing chamber.Mix from mixing the tube outlet of phase garden, or/and mix outlet mutually from rectangle, flow in the pallet on the mixing chamber top and clarify, mix the portable plate of outlet mutually by regulating rectangle, and/or the garden tube mixes the movable tube high and low position of outlet mutually, can control the size of mixing the phase export volume.The heavy phase of clarifying on the pallet (the perhaps same not mixing phase of phase-splitting), the pallet overfall that overflow arrives Entry Interface district (or further clarification).Pallet heavy phase overfall has the overfall adjustable plate, regulates this plate and can control pallet weighed boundary height.Light phase after clarification phase passage on the lenient side flows in upper level (or next stage) mixing chamber, and the heavy phase after the clarification flows to the mixing chamber of next stage (or upper level) from the heavy phase channels interface adjustable plate that overflow.
