Description

Technical Field

[0001] The utility model relates to the technical field of oil extraction auxiliary equipment, in particular to a multifunctional rosemary essential oil processing device. Background Technique

[0002] Rosemary essential oil is a colorless to light yellow liquid and is a spice with a long history, widely used in fields such as perfumes, cosmetics, medicine, soaps, and air fresheners. Rosemary essential oil has the effects of conditioning greasy and unclean skin, promoting blood circulation, and stimulating hair growth; it has the effects of reducing skin congestion, swelling, and edema, and can astringe the skin and improve dandruff; it has the effects of relieving menstrual pain, diuresis, weight loss, and has a health care effect on the stomach, intestines, heart, lungs, liver, and gallbladder; it also has the effects of lowering blood pressure, conditioning anemia, refreshing the mind, and restoring the vitality of the central nervous system. The extraction methods of rosemary essential oil mainly include the following, such as steam distillation method, solvent rectification method, ultrasonic extraction method, supercritical carbon dioxide extraction method, microwave extraction method, enzymatic hydrolysis method, microcapsule aqueous two-phase extraction method, etc., which are too numerous to mention. Among them, the solvent rectification method has the advantages of high extraction rate (the extraction rate is 92.38%), good stability, high purity of the extract, relatively convenient operation, and relatively low cost. Therefore, this method is widely used in actual production. Specifically, one or more organic solvents such as petroleum ether, n-hexane, ethyl acetate, acetone, and ethanol are used as extraction solvents to dissolve the active substances in the dried and crushed raw materials for rosemary essential oil extraction (olea europaea) (extraction process), and then the rectification solvent is evaporated by evaporation and condensed by a condenser through filtration, and then the finished product of rosemary essential oil is obtained.

[0003] Although the existing solvent extraction equipment meets the production needs to a certain extent, due to structural limitations, there are still some technical drawbacks as follows. First: The solvent is evaporated by heating in a static state. In this way, the evaporation state is relatively single and the evaporation speed is relatively slow, resulting in relatively low work efficiency. Second: Before the rectification solvent and essential oil mixture enter the rectification tank, it is generally only filtered through a single-stage filtration device. In this way, the filtration effect is relatively poor. Further, relatively more raw material residues precipitate at the bottom of the rectification tank, and the staff needs to open the rectification tank for cleaning at relatively short time intervals, which brings inconvenience to the staff and correspondingly reduces the work efficiency. In summary, it is very necessary to provide a rosemary essential oil rectification device that can improve work efficiency and product quality. Content of the Utility Model

[0004] In order to overcome the drawbacks described in the background due to structural limitations of existing rosemary oil rectification processing equipment, the present utility model provides a multifunctional rosemary essential oil processing device which, under the combined action of relevant mechanisms, enables the solvent components in the mixed liquid in the rectification tank body to evaporate relatively faster into the condenser to be cooled into a liquid through heating and negative pressure air extraction methods, and the mixed liquid before entering the rectification tank body can be filtered through multiple-stage filters, reducing the amount of raw material residues entering the rectification tank body, improving work efficiency and correspondingly bringing convenience to the staff.

[0016] Figure 1 、 2As shown in the figure, there is a rectangular opening at the lower front outer side of the rectifying tank body 1. The opening is equipped with a movable plate 5. The side end of the opening has multiple threaded holes.

The prompting circuit includes an operational amplifier W4, resistors R1, R2, R3, R4, R5, a triode Q1, and a buzzer B1, which are connected through circuit board wiring; one end of the first resistor R1, one end of the second resistor R2, and the non-inverting input terminal 3 of the operational amplifier W4 are connected; one end of the third resistor R3, one end of the fourth resistor R4, and the inverting input terminal 2 of the operational amplifier W4 are connected; the output terminal 6 of the operational amplifier W4 and one end of the fifth resistor R5 are connected; the positive power input terminal 7 of the operational amplifier W4 and the positive power input terminal of the buzzer B are connected; the other end of the fifth resistor R5 and the base of the triode Q1 are connected; the collector of the triode Q1 and the negative power input terminal of the buzzer B are connected; the other ends of the second resistor R2 and the fourth resistor R4 and the negative power input terminal 4 of the operational amplifier W4 and the emitter of the triode Q1 are connected. One side end of the liquid inlet pipe 24 of the upper set of filtering mechanisms and one side end of the liquid discharge pipe 25 of the lower set of filtering mechanisms respectively have a threaded hole. The liquid inlet pipes of two pressure switches W2 and W3 are respectively screwed into the two threaded holes through threads and installed at the side ends of the liquid inlet pipe 24 and the liquid discharge pipe 25. The condensing mechanism includes a metal housing 43, a serpentine condensing pipe 44, and a semiconductor refrigeration mechanism M1. The serpentine condensing pipe 44 is hermetically installed inside the housing 43, and its upper liquid inlet pipe A41 and lower liquid discharge pipe A42 are respectively located outside the upper and lower ends of the housing 43. Multiple sets of semiconductor refrigeration mechanisms M2 are respectively installed outside the front side end of the housing 43 from top to bottom.

[0017] Figure 1 , 2 As shown in the figure, the power input terminals 1 and 2 of the power supply module W1 and the two poles of the AC 220V power supply are respectively connected through wires. The power output terminals 3 and 4 of the power supply module W1 and the power input terminals 1 and 2 of the pressure switches W2 and W3, the power input terminals 7 and 4 of the operational amplifier W4 of the prompting circuit, and the power input two ends of multiple sets of semiconductor refrigeration mechanisms M1 of the condensing mechanism are respectively connected through wires. The signal output terminals 3 of the pressure switches W2 and W3 and the signal input terminals 3 and 2 of the operational amplifier W4 of the prompting circuit are respectively connected through wires. The power input terminal of the electric air pump M2 is connected in series through a power switch S1, and the power input terminals of two electric heating tubes RT are connected in series through a temperature switch D1 and the two poles of the AC 220V power supply are respectively connected through wires.

[0018] Figure 1 , 2As shown, when the main power switch is turned on and the power module W1 is powered on, the stable DC 12V power supply output from pins 3 and 4 of the power module W1 enters the power input terminals of the two pressure sensors W2, W3 and the prompting circuit, and the above-mentioned mechanisms are powered on to work. During the production of this application, after the active substances in the raw materials for rosemary essential oil extraction (herba pectinatulae) are dissolved (extraction process) after drying and pulverization in the previous process, they enter the filter screen 22 of the upper set of filtering mechanisms through the liquid inlet pipe 24 (the liquid outlet pipe of the extraction equipment and the upper end of the liquid inlet pipe 24 are connected by a pipeline). After the mixed liquid is filtered by multiple sets of filtering mechanisms, it enters the rectifying tank body 1 through the liquid discharge pipe 25 of the lower set of filtering mechanisms. After the electric heating tube RT is powered on, it generates heat and heats the mixed liquid in the rectifying tank body 1 (the evaporation temperature of rosemary essential oil is about 190°C). When the temperature in the rectifying tank body 1 is lower than a certain value (for example, when ethanol is used as the solvent and the temperature is lower than 100°C), the internal contacts of the temperature switch D1 are closed. In this way, the electric heating tube RT is powered on to generate heat and heat the mixed liquid in the rectifying tank body 1; when the temperature in the rectifying tank body 1 is higher than a certain value (for example, the temperature is higher than 100°C), the internal contacts of the temperature switch D1 are open. In this way, the electric heating tube RT is no longer powered on to generate heat to heat the mixed liquid in the rectifying tank body 1. Through the above, this new type can evaporate the solvent under a constant temperature state. After the power switch S1 is turned on, the electric air pump M2 is powered on to work and generates a negative pressure to extract the gas during evaporation. Due to the effect of the negative pressure, the solvent components in the mixed liquid in the rectifying tank body 1 can evaporate relatively faster into the condenser and be cooled into a liquid. After the condenser mechanism works, several sets of semiconductor refrigeration mechanisms M1 are powered on to work and cool the outer shell 43. The temperature inside the outer shell is below 20°C. Since the temperature of the solvent (such as ethanol, whose condensation temperature is 78.5°C) is lower than the temperature of the solvent, the solvent entering the serpentine condenser tube 44 is cooled into a liquid and enters the recovered solvent tank. After the subsequent solvent has completely volatilized, the staff places the finished essential oil tank under the valve 6, opens the valve 6, and the essential oil will automatically flow into the essential oil tank. After the outflow is complete, the valve 6 is closed.

[0019] Figure 2As shown in the figure, after the two pressure sensors W2 and W3 are powered on and working, their signal output terminals will output a voltage signal that changes dynamically with the intake pipe pressure to pins 3 and 4 of the operational amplifier W2. When the filter is not blocked (the liquid flows smoothly, and the pressure in the liquid inlet pipe 24 of the upper set of filtering mechanisms is relatively low), the voltage signal output from pin 3 of the pressure sensor W2 is relatively low. This voltage signal is divided by resistors R1 and R2 and enters pin 3 of the operational amplifier W4 (such as 3V), which is lower than the voltage signal output from pin 3 of the pressure sensor W3 and divided by resistors R3 and R4 and enters pin 3 of the operational amplifier W4 (such as 3.1V). The output of pin 6 of the operational amplifier W4 is a low level. Then, the buzzer B will not be powered on and sound, indicating that the filter is not blocked. When one or more sets of filters are blocked (the liquid flow is no longer smooth, and the pressure in the liquid inlet pipe 24 of the upper set of filtering mechanisms is relatively high), the voltage signal output from pin 3 of the pressure sensor W2 is relatively high. This voltage signal is divided by resistors R1 and R2 and enters pin 3 of the operational amplifier W4 (such as higher than 3.2V), which is higher than the voltage signal output from pin 3 of the pressure sensor W3 and divided by resistors R3 and R4 and enters pin 2 of the operational amplifier W4. The output of pin 6 of the operational amplifier W4 is a high level. The high level is limited in current and stepped down by resistor R5 and enters the base of the triode Q1. The triode Q1 conducts, and the collector outputs a low level and enters the negative power input terminal of the buzzer B. The buzzer B is powered on and sounds, indicating that a filtering mechanism is blocked. Subsequently, the operator can open the sealing plate at the front end of the outer shell 26 to clean or replace the corresponding filtering mechanism, etc. Figure 2 As shown in the figure, the electric heating tube RT is a finished product of a dry-burning type electric heating tube with a power of 1500W and a brand of COOKRHOUL / Coolkao; the power supply module W1 is a finished product of an AC 220V to DC 12V switching power supply module; the temperature switch D1 is a finished product of a 100°C snap-action normally closed contact temperature switch of model KSD301; the semiconductor refrigeration mechanism M1 has a power of 120W (its cold end is closely attached to the outer box body, and the hot end is located outside); the operational amplifier W4 is of model UA741; the triode Q1 is an NPN type triode of model 9013; the buzzer B is a finished product of an active continuous sound buzzer alarm of model FM12; the resistance values of resistors R1, R2, R3, R4, and R5 are 10K, 9.8K, 10K, 10K, and 4.7K respectively; the electric air pump M has a power of 1.2KW; the pressure sensors W3 and W2 are pressure transmitters of model PCM300, which have two power input terminals and one signal output terminal.
