Detailed Description
The present invention will be further explained with reference to the drawings and the embodiments.
Example 1
The utility model provides an evaporative condenser return flow detection device, as shown in fig. 1, fig. 2, the device includes four-way mirror 1 the design installation mould 3 is erect to two side lens 2 outsides of four-way mirror 1, as shown in fig. 3, wherein set up light source 4 (from top to bottom equidistance is arranged or regular a plurality of laser-induced tube) on the design installation mould 3 of one side, make light pass lens 2 and the liquid medium 6 in the pipeline from one side with setting for the incident angle, as shown in fig. 4, set up the same quantity light source receiver 5 (same equidistance or regular arrangement) on the design installation mould 3 of the corresponding position that the light source incides opposite side lens 2, receive and respond to the light signal.
The upper end and the lower end of the shaping installation mould 5 are provided with adjusting devices, so that the emitted light level is guaranteed.
When there is liquid medium 6 in the horizontal pipeline, light passes liquid medium 6 and takes place the refraction for light source receiver 5 that corresponds can not sense light, and the controller judges the liquid level height of liquid medium 6 in the horizontal pipeline through the operating condition who gathers these light source receiver 5, can correspond the size of calculating back flow volume in the pipe according to the liquid level height.
Light absorbing materials are adopted on the bottom plates of the light emitting side and the light receiving side except the positions of the light source 4 and the light source receiver 5, so that misoperation caused by reflected light is avoided.
As shown in fig. 3 and 4, two mutually perpendicular axes of the four-way mirror 1 are respectively provided with a level gauge 15, which is mainly used for judging whether the device is level on the X axis and the Y axis when the device for detecting the reflux amount of the evaporative condenser is installed, and the device is required to be installed horizontally when in use.
As shown in fig. 5, the above-mentioned evaporative condenser reflux amount detection apparatus 10 is applied to distillation separation of organic mixed oil, and specifically includes the following steps: mother liquor (such as methanol and tetracene mixed liquor) is added into a mother liquor distillation kettle 8 from a mother liquor inlet 7, the temperature of the mother liquor distillation kettle 8 is raised, when the temperature reaches a certain low oil boiling point (such as 70 ℃ of methanol), the oil is firstly vaporized and enters a condenser 9 through a pipeline, the condensed oil becomes liquid and flows through an evaporative condenser reflux amount detection device 10, a valve 13 is opened by a controller, the liquid flows into a front fraction receiving kettle 11, because the evaporation capacity is little at the beginning, and the liquid level is low, and evaporation capacity is big along with the temperature rise, and liquid flow is big, and the liquid level in the evaporative condenser return flow detection device 10 rises, and along with the evaporation is close the end sound, evaporation capacity reduces, and the flow reduces, and the liquid level in the evaporative condenser return flow detection device 10 descends, and evaporative condenser return flow detection device 10 is through detecting the liquid level low to the lower limit, and the controller closes valve 13, opens valve 14 simultaneously, gets into back fraction receiving tank 12 and carries out the distillation separation.
The utility model discloses utilize light to have different refraction angle principle detection medium liquid level through air and organic medium, transmitting light source and light source receiver pair in groups, transmitting light source generally is laser emitting source, when not having the medium, transmitting light source is with the incident angle transmission parallel light of setting for, and upper and lower equidistance is arranged, and light is received to the light source receiver homoenergetic that corresponds, exports corresponding signal, gives the controller. The light emitting tube is fixedly arranged on the shaping installation mould, and the incident angle is ensured to be a design value; the upper end and the lower end of the die are provided with adjusting devices to ensure the level of emitted light. The luminotron adopts a plurality of groups of equidistant vertical installation outside the lens at one side of the four-way sight glass, so that light rays pass through the lens, the four-way sight glass and the lens at the other side from one side at a certain incident angle, and the same number of light source receivers are arranged at corresponding positions outside the lens at the other side for receiving and sensing light signals.
