Its separation principle is to open corresponding solenoid valve according to condenser liquid stream amount size and organic oil vaporization sequence.Presently mainly
Manual method includes a four-way photoscope in reflux unit, corresponding by eye-observation reflux unit liquid level variation switch
Valve, as temperature rises certain value in distillation still, the oil (such as methanol) of low boiling point is begun vaporization, and is cooled to liquid through condenser
Backflow detecting device is flowed through, backflow detecting device includes one or four way view mirrors, since the oil of low boiling point just begins vaporization condensed fluid
Amount is few, and flow is small, and liquid level is low at photoscope, and as the temperature rises, and flow increases, and liquid level rises, then as a kind of organic oil
Vaporization draws to an end, and flow reduces, liquid level decline, according to this rule, judges that a kind of organic matter vaporization terminates, closes before dividing and evaporate
Kettle is received, reception kettle is evaporated after being then turned on, is separated into next organic oil Vaporizing cooling.Since flow is small, usual maximum stream flow
It is 100 ls/h, flow velocity is slow, currently on the market without this small range flow meter or liquidometer, eye-observation is mainly used,
And human eye judges that liquid level changes, manpower demand amount is big, large labor intensity, and separation is not accurate enough, and working efficiency is lower；And it works
Bad environments, harm to the human body are big.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of evaporative condenser reflux amount detecting device, can be improved certainly

Specific embodiment
The present invention is further elaborated with embodiment with reference to the accompanying drawing.
Embodiment 1
A kind of evaporative condenser reflux amount detecting device, as shown in Figure 1 and Figure 2, described device includes four way view mirrors 1, in institute
It states and is provided with sizing installation mold 3 on the outside of the two sides lens 2 of four way view mirrors 1, as shown in figure 3, wherein mould is installed in the sizing of side
Light source 4 (upper and lower equidistant arrangement or several regular lasing fluorescence pipes) are set on tool 3, make light to set incidence angle from side
Liquid medium 6 in lens 2 and pipeline, as shown in figure 4, in the light source incidence to the corresponding position of other side lens 2
Sizing installation mold 3 on the light source receiver 5 (same equidistant or regular arrangement) of identical quantity is set, receive and induction light
Signal.
5 upper and lower side of installation mold of being formed has regulating device, guarantees transmitting light level.
When there is liquid medium 6 in horizontal pipe, light passes through liquid medium 6 and reflects, so that corresponding light source connects
Light cannot be sensed by receiving device 5, and controller is by acquiring the working condition of these light source receivers 5 come liquid in determined level pipeline
The liquid level of body medium 6 can correspond to the size for calculating regurgitant volume in outlet pipe according to liquid level.
Light emitting side, receiving side bottom plate are all made of light absorbent other than 5 present position of light source 4 and light source receiver,
Reflection light is avoided to cause to malfunction.
As shown in Figure 3, Figure 4, it is each provided with a level meter 15 on two orthogonal axis of four way view mirrors 1, it is main
When being used for evaporative condenser reflux amount detecting device installation, whether judgment means guarantee level in X-axis and Y-axis, it is desirable that make
It must be horizontally mounted with middle device.
As shown in figure 5, the distillation that above-mentioned evaporative condenser reflux amount detecting device 10 is applied to organic miscella is separated,
Specific as follows: mother liquor (such as methanol, two or four benzene mixed liquors) is added from mother liquor entrance 7 to mother liquor distillation still 8,8 temperature of mother liquor distillation still
Degree increases, and when temperature reaches certain low oily boiling point (such as 70 DEG C of methanol), this oil is first vaporized, and enters condenser 9 through pipeline, passes through
Evaporative condenser reflux amount detecting device 10 is flowed through at liquid after condensation, controller Open valve 13, liquid flows into front-end volatiles and connects
Kettle 11 is received, evaporating capacity is small when due to starting, and liquid level is low, and as the temperature rises, and evaporating capacity is big, and fluid flow is big, and evaporative condenser returns
Liquid level in flow detector 10 rises, and as vaporization draws to an end, evaporating capacity is reduced, and flow reduces, and evaporative condenser returns
Liquid level decline in flow detector 10, evaporative condenser flow back amount detecting device 10 by detecting liquid level down to lower limit, control
Device processed closes valve 13, while Open valve 14, receives kettle 12 into tails and carries out distillation separation.
The present invention by air and organic media there is different refraction angle principles to detect medium liquid level, transmitting using light
Light source and light source receiver match in groups, transmitting light source be usually lasing fluorescence source, when there is no medium, emit light source with
The incidence angle emitting parallel light set, upper and lower equidistant arrangement, corresponding light source receiver can receive light, and output is corresponding
Signal gives controller.Luminous tube is fixedly mounted on sizing installation mold, and guarantee incidence angle is design value；Above and below mold
End has regulating device, guarantees transmitting light level.Luminous tube is equidistantly mounted on four way view mirror side lens using multiple groups up and down
Outside, light is made to pass through lens and four way view mirrors and other side lens from side with certain incidence angle, it is corresponding outside the lens of the other side
Same amount of light source receiver is placed in position, receives and incude optical signal.When in four way view mirrors being air, such as Fig. 6 (a) institute
Show, adjusts the position of light source and light source receiver, make light source receiver that can receive light；When having liquid in four way view mirrors
When medium, the opticpath on liquid level is constant, and corresponding light source receiver can receive light, subsurface light, such as Fig. 6
(b) shown in, because refractive index and the refractive index in air are different, opticpath is changed, and corresponding light source receiver is equal
Can't accept signal, be based on this principle, determine medium liquid level the light source receiver that can receive light with cannot receive
Between the light source receiver of light.Judge whether the distillation of certain organic matter terminates according to the liquid level lower limit set, convenient for switch
Corresponding valve reaches the automatic control of organic matter separation, realizes that prosthetic participates in, improves degree of automation and efficiency.
