Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for extraction devices, in particular to post-processing equipment for distillation of geranium essential oil. Background Art

[0002] Geranium essential oil is a commonly used natural aromatic substance with a comprehensive sweetness, a complex taste of rose and mint. Geranium essential oil is colorless or light green and is often used in the fields of beauty and medicine. Geranium essential oil is generally extracted by the extraction method, and the collected flowers and leaves of the geranium tree are prepared through processes such as crushing, distillation, and separation (collectively referred to as extraction). Specifically, the staff crushes the washed raw materials through a crushing equipment, and then sends the raw materials mixed with water into a distiller for distillation, and the condensation mechanism condenses the water vapor and essential oil gas into liquid. Finally, the geranium essential oil obtained by distillation is collected through a collection device, and the final geranium essential oil product is obtained after separating the water.

[0003] Although the existing geranium essential oil extraction device meets the production needs to a certain extent, it is limited by the structure and still has the following shortcomings. Specifically, its condensing mechanism generally uses water cooling to cool the water vapor and essential oil gas after distillation. The cooling effect of water is relatively limited and cannot guarantee that all essential oils can be converted from gas to liquid (especially when the amount of essential oil and steam produced by distillation is large, and the cooling water flow rate is fixed, or the ambient temperature is relatively high). In this way, the gas discharged by the condensing mechanism contains more or less essential oil gas, which will cause unnecessary waste. In summary, it is very necessary to provide a post-processing device that can be used in conjunction with the condensing mechanism to re-condense and recover the geranium essential oil in the exhaust gas discharged by the condensing mechanism. Utility Model Content

[0004] In order to overcome the existing geranium essential oil extraction device, the condensing mechanism used in conjunction with it cannot effectively ensure that all the essential oil is extracted due to structural limitations.

[0005] In order to overcome the drawbacks of extraction and recovery, the utility model provides a geranium essential oil distillation post-processing device that provides a coordinated condensation mechanism. During application, the essential oil-containing gas discharged from the exhaust pipe of the condensation mechanism can be cooled again through water cooling and semiconductor refrigeration mechanisms, so that a small amount of essential oil discharged from the condensation mechanism can also be recycled, thereby correspondingly improving the production efficiency.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

The semiconductor refrigeration module is installed on the outside of the shell, and ventilation pipes are respectively installed on the side end and the upper end of the shell. The shell is installed on the side end of the bottom plate, and the vacuum pump A is installed on the upper end of the shell.

[0009] Furthermore, the finished product tank is made of transparent material, and there is an opening on the front side of the water cooling box, and a transparent observation plate is installed in front of the opening.

[0010] Furthermore, the drainage mechanism includes a guide pipe and a drainage pipe. The guide pipe is installed on one side of the upper part of the water cooling box. An elastic sealing pipe is installed in the guide pipe. Bolts are installed on the outside of the guide pipe. The drainage pipe is movably sleeved in the sealing pipe. A guide pipe is installed on one side of the upper end of the drainage pipe. The upper end branch pipe of the cooling pipe is respectively connected in parallel to one end of two valves A, and the other end of one of the valves A is connected to the upper end of the guide pipe.

[0011] Furthermore, the upper end of the finished product tank is provided with a liquid inlet.

[0012] Furthermore, the height of the drainage pipe is higher than the height inside the water cooling box.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the utility model is used in conjunction with the condensing mechanism of the geranium essential oil extraction device. In application, the essential oil-containing gas discharged from the exhaust pipe of the condensing mechanism can be cooled again through a water cooling box, a semiconductor refrigeration mechanism, etc. When the amount of recovered essential oil liquid reaches a certain amount, the staff can conveniently generate negative pressure through a pump to extract the essential oil in the water cooling box into the finished product tank. The utility model allows a small amount of essential oil discharged from the condensing mechanism to be recycled, thereby correspondingly improving production efficiency.

[0018] Figure 1 , 2As shown in , a one-way air valve 7 is installed at the upper rear end of the water cooling box (the air intake pipe and the water cooling box are interconnected, and the one-way air valve 7 discharges the excess air in the water cooling box), and a manual stop valve 81 and 82 are installed at the front of the lower left end of the water cooling box and the middle of the lower left end of the finished product tank (the inlet of the valve is interconnected with the water cooling box and the finished product tank respectively). The finished product tank 1 is made of transparent plastic material, and there is a rectangular opening vertically at the left end of the front side of the water cooling box 2. A transparent plastic observation plate 26 is sealed and glued in front of the opening (the left and right ends of the water cooling chamber at this position are sealed and isolated from the observation plate 26, and the upper end of the water cooling chamber is interconnected). The drainage mechanism includes a guide tube 91 and a "˥"-shaped drainage tube 92. The lower end of the guide tube 91 is welded to the middle of the left end of the water cooling box 2 and the lower end of the guide tube 91 is interconnected with the water cooling box 1. A hollow rubber sealing tube 93 is glued in the guide tube 91. There is a thread hole on the outside of the middle part of the guide tube. A manual fixing screw 94 is screwed into the thread hole through a thread. The right end of the drainage tube 92 is vertically sealed in the guide tube 91 and the sealing tube 93. A guide tube 94 that is interconnected with the inside of the drainage tube 92 is vertically welded to the upper left end of the drainage tube 92. The outer side of the lower side branch pipe 41 on the upper left end of the cooling tube 2 is connected to the first end of a three-way pipe through a pipe joint. The second end and the third end of the three-way pipe are connected to one end of two manual stop valves A95 through pipe joints respectively, and the other end of one of the valves A95 is connected to the upper end of the guide tube 94 through a pipe. There is a liquid inlet 101 in the middle of the upper end of the finished product tank 1, and the middle of the liquid inlet 101 is located at the lower left end of the drainage tube 92. The vertical height of the right end of the drainage tube 92 is higher than the height in the water cooling box 2, and the right end of the drainage tube 92 and the inner side of the rubber sealing tube 93 are in a sealed sliding structure. The power input terminals 1 and 2 of the power module A1 are connected to the two poles of the AC 220V power supply through wires, respectively, the power output terminals 3 and 4 of the power module A1 are connected to the power input terminals of the semiconductor refrigeration module M and the air pump AM1 through wires, respectively, and the power input terminal of the air pump M2 is connected in series with the power output terminals 3 and 4 of the power module A1 through the power switch S1, respectively, through wires.

[0019] Figure 1 , 2As shown, the condensing mechanism of the novel collaborative geranium essential oil extraction device (geranium essential oil extraction device is a mature technology, and this application will not repeat it). After the AC 220V power supply enters the power input end of the power module A1, the power module A1 outputs a stable DC 12V power supply to enter the power input end of the semiconductor refrigeration module M and the air pump AM1 (after the power switch S1 is turned on, the air pump M2 is powered on to work and the mixed gas discharged from the exhaust pipe of the condensing mechanism is sucked into the cooling pipe 4), the two sets of semiconductor refrigeration modules M and the air pump AM1 are powered on, and after the air pump AM1 is powered on, the external air is sucked into the shell 5, and the two sets of semiconductor refrigeration modules M cool the shell, and the air entering the shell is correspondingly cooled, and the cooled air enters the air cooling chamber 25 (one valve A95 is closed, and the other valve A95 is opened, and the air that cools and absorbs heat is discharged outward through the other valve A95), and the mixed gas containing geranium essential oil and water vapor discharged from the condensing mechanism in the cooling pipe 4 is cooled again. Tap water flows in through the water inlet pipe 22 and flows out through the water outlet pipe 23. During the process of cooling water flowing in and out, the liquid and a small amount of residual mixed gas entering the water cooling box 2 will be cooled again. After cooling, the essential oil and water are collected in the water cooling box. When the geranium essential oil extraction device stops working (or stops working for many times), the staff turns off the power switch of the air pump M2, and then closes another valve A95. The staff observes the distribution of the essential oil and liquid water in the water cooling box 2 through the observation plate 26 (the specific gravity of water is large and located at the lower end of the essential oil), and then loosens the screw 94, and adjusts the height of the drainage pipe 92 along the guide pipe 91 up or down, so that the lower right end of the guide pipe 91 is located at a certain position at the lower end of the essential oil (located about 2 mm above the water, the main purpose is to prevent the drainage pipe from pumping water into the finished product tank), and then tightens the screw 94, and the drainage pipe is at a suitable height and no longer moves. Then, the staff opens one of the valves A95 by hand, and the gas discharged from the vacuum pump AM1 is discharged downward at high speed through one of the valves A95 and the guide pipe 94 (discharged downward from the upper left end of the drainage pipe). In this way, negative pressure will be generated at the right end of the drainage pipe, and the geranium essential oil will flow into the finished product tank 1 through the left end of the drainage pipe. After the essential oil is extracted, all power switches are turned off. After a period of time (it can also be after multiple extractions of essential oils), the staff opens valve 82, so that the essential oil in the finished product tank 1 will flow out into other low-level transfer tanks, etc.; after opening valve 81, the water in the water cooling tank 2 will flow out into the waste water tank (the other end of the valve is connected to the liquid inlet pipe of the waste water tank through a pipeline). After the water is discharged, the valve is closed to prevent the remaining essential oil inside from being discharged and causing waste. This new type allows the small amount of essential oil discharged by the condensing mechanism to be recycled, which correspondingly improves the production efficiency.
