Description

Technical Field

[0001] The present invention relates to the technical field of plant essential oil purification, and more specifically, it relates to an extraction and purification device for continuous production of gardenia essential oil. Background Art

[0002] Gardenia essential oil is a natural aromatic substance extracted from Gardenia jasminoides. It is used in aromatherapy, skin care, mood regulation and other fields due to its unique aroma and potential efficacy. Distillation is the oldest and most widely used method for extracting essential oils. The process involves heating the plant in a distillation container with water or steam (or both) to expel the water vapor, thus producing a concentrated liquid.

[0003] After distilling and extracting gardenia essential oil, the distilled gardenia essential oil is purified by filtration, mainly to remove residual solid particles, moisture, gum or other impurities to improve the purity, stability, safety and quality of gardenia essential oil. In the prior art, the plant gardenia essential oil is usually filtered and purified through a filter screen. Although a good purified product can be obtained, since the filter screen is easily blocked and needs to be replaced in time, and during filtration, the gardenia essential oil passes through the filter screen by its own gravity, resulting in low filtration efficiency of the gardenia essential oil. Summary of the Invention

[0004] The present invention overcomes the problems in the prior art that when purifying essential oils by filtration, since the filter screen is easily blocked and needs to be replaced in time, and during filtration, the essential oil passes through the filter screen by its own gravity, resulting in low filtration efficiency of the essential oil; provided an extraction and purification device for continuous production of gardenia essential oil, which can extend the replacement time of the filter screen, reduce the efficiency of delaying the purification of gardenia essential oil due to replacing the filter screen, and can improve the efficiency of the essential oil passing through the filter screen, thereby improving the extraction and purification efficiency of gardenia essential oil.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: An extraction and purification device for continuous production of gardenia essential oil, comprising: A filtering component, including a filtering tank, an arc-shaped filter plate arranged in the filtering tank, and an arc-shaped filtering sponge arranged above the arc-shaped filter plate. An arc-shaped filter screen is arranged between the arc-shaped filtering sponge and the arc-shaped filter plate. A number of through holes are evenly distributed on the arc-shaped filter plate; an oil outlet cavity is formed by the cooperation between the arc-shaped filter plate and the bottom of the filtering tank; The extrusion assembly includes a rotating shaft disposed above the arc-shaped filter sponge, an extrusion cam disposed on the rotating shaft, and a driving motor connected to the rotating shaft; an extrusion section and a cleaning section are provided on the outer side of the extrusion cam; a cleaning brush is provided on the outer surface of the cleaning section; the diameter of the rotating shaft from the surface of the arc-shaped filter sponge is D, the rotation radius of the extrusion section is greater than D, and the rotation radius of the cleaning section is less than or equal to D; The oil storage barrel has an oil outlet at the bottom, the oil outlet is communicated with an oil pipeline, and the output end of the oil pipeline is disposed above the arc-shaped filter sponge.

[0006] In the present invention, the gardenia essential oil to be purified is stored in the oil storage barrel. The gardenia essential oil flows from the bottom oil outlet through the oil pipeline and then reaches the arc-shaped filter sponge. After the gardenia essential oil is absorbed by the arc-shaped filter sponge, the impurities in the gardenia essential oil remain on the upper end surface of the arc-shaped filter sponge; at the same time, the driving motor rotates to drive the rotating shaft to rotate, and the rotating shaft drives the extrusion cam to rotate. When the extrusion section on the extrusion cam passes through the arc-shaped filter sponge, the extrusion section will extrude the arc-shaped filter sponge, thereby extruding the gardenia essential oil in the arc-shaped filter sponge. After the extruded gardenia essential oil passes through the arc-shaped filter net, it passes through the perforations of the arc-shaped filter plate and drips into the oil outlet cavity, and then flows out from the oil outlet cavity for further processing. After the extrusion section extrudes the arc-shaped filter sponge, the amount of essential oil in the arc-shaped filter sponge at this time decreases. Therefore, when the new gardenia essential oil flows above the arc-shaped filter sponge, it will be quickly absorbed by the arc-shaped filter sponge, and the impurities therein (such as dust and solid particles) will fall above the arc-shaped filter sponge; when the cleaning section passes through the arc-shaped filter sponge, the cleaning brush on the cleaning section will clean the impurities above the arc-shaped filter sponge to prevent the impurities from accumulating above the arc-shaped filter sponge.

[0007] Therefore, when filtering the gardenia essential oil in this application, the preliminary filtration is achieved through the arc-shaped filter sponge, and most of the impurities are filtered on the surface of the arc-shaped filter sponge, thereby effectively reducing the blockage of impurities on the surface of the arc-shaped filter net, prolonging the service life of the arc-shaped filter net, and reducing the time spent on replacing the filter net. And through the cooperation of the extrusion cam and the arc-shaped filter sponge, the filtration efficiency of the gardenia essential oil can be improved, and at the same time, the impurities on the surface of the arc-shaped filter sponge can be cleaned. And the overall structure adopts a pure mechanical structure, which can effectively avoid the influence on the gardenia essential oil.

[0008] Preferably, an oil inlet groove is provided on one side of the filter tank, and the outlet of the oil pipeline is communicated with the oil inlet groove; a diversion groove communicated with the oil inlet groove is provided at one end of the arc-shaped filter sponge, and the length direction of the diversion groove is perpendicular to the rotating shaft.

[0009] Preferably, the oil inlet groove is provided at the middle position of the filter tank.

[0010] Preferably, a dust collecting groove is provided at one end of the arc-shaped filtering sponge away from the diversion groove, and the length direction of the dust collecting groove is parallel to the rotating shaft; a dust discharging groove communicating with the dust collecting groove is provided on the side wall of the filtering groove.

[0011] Preferably, the bottom of the filtering groove is arc-shaped.

[0012] Preferably, an oil outlet pipe communicating with the oil outlet cavity is provided at the bottom of the filtering groove.

[0013] Preferably, support plates are provided on both sides of the filtering groove, support bearings are provided on the support plates, the rotating shaft is arranged on the support bearings on the two support plates; the extrusion cam is arranged between the two support bearings.

[0014] Preferably, a closed cover cooperating with the filtering groove is provided above the filtering groove, and slots cooperating with the two support plates are provided on both sides of the closed cover.

[0015] Preferably, the bottom of the oil storage barrel is conical, and the oil outlet is arranged at the bottom of the cone.

[0016] Preferably, a filtering box is further included, the filtering assembly and the extrusion assembly are arranged in the filtering box, and the oil storage barrel is arranged on the top of the filtering box.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the gardenia essential oil to be purified is stored in the oil storage barrel. The gardenia essential oil flows from the oil outlet at the bottom through the oil pipeline and then flows onto the arc-shaped filtering sponge. After the gardenia essential oil is absorbed by the arc-shaped filtering sponge, the impurities in the gardenia essential oil remain on the upper end surface of the arc-shaped filtering sponge. At the same time, the driving motor rotates to drive the rotating shaft to rotate, and the rotating shaft drives the extrusion cam to rotate. When the extrusion section on the extrusion cam passes through the arc-shaped filtering sponge, the extrusion section will squeeze the arc-shaped filtering sponge, so as to squeeze out the gardenia essential oil in the arc-shaped filtering sponge. After the squeezed-out gardenia essential oil passes through the arc-shaped filter screen, it passes through the perforations of the arc-shaped filter plate and drips into the oil outlet cavity, and then flows out of the oil outlet cavity and is further processed. After the extrusion section squeezes the arc-shaped filtering sponge, the amount of essential oil in the arc-shaped filtering sponge at this time decreases. Therefore, when the new gardenia essential oil flows above the arc-shaped filtering sponge, it will be quickly absorbed by the arc-shaped filtering sponge, and the impurities therein (such as dust and solid particles) will fall above the arc-shaped filtering sponge. When the cleaning section passes through the arc-shaped filtering sponge, the cleaning brush on the cleaning section will clean the impurities above the arc-shaped filtering sponge to prevent the impurities from accumulating above the arc-shaped filtering sponge.

[0018] Therefore, when filtering gardenia essential oil in this application, preliminary filtration is achieved through an arc-shaped filter sponge, and most impurities are filtered on the surface of the arc-shaped filter sponge, which can effectively reduce the blockage of impurities on the surface of the arc-shaped filter net, extend the service life of the arc-shaped filter net, and reduce the time spent on replacing the filter net. Moreover, through the cooperation of the extrusion cam and the arc-shaped filter sponge, the filtration efficiency of gardenia essential oil can be improved, and at the same time, the impurities on the surface of the arc-shaped filter sponge can be cleaned. And the overall structure adopts a pure mechanical structure, which can effectively avoid affecting the gardenia essential oil. Brief Description of the Drawings

[0027] The following will further specifically describe the technical solutions of the present invention through specific embodiments in conjunction with the drawings: Example 1: Refer to Figures 1 to 5 As shown, a continuous production extraction and purification equipment for gardenia essential oil includes: a filtration tank 1, in which a filtration component 2 and an extrusion component 3 are arranged. At the top of the filtration tank 1, there is an oil storage barrel 4, and the essential oil to be filtered and purified is stored in the oil storage barrel 4. At the top of the oil storage barrel 4, there is a top inlet 41, and the gardenia essential oil enters the oil storage barrel 4 from the top inlet 41.

[0028] The filtration component 2 includes a filtration tank 21, an arc-shaped filter plate 22 arranged in the filtration tank 21, and an arc-shaped filter sponge 23 arranged above the arc-shaped filter plate 22. An arc-shaped filter net 24 is arranged between the arc-shaped filter sponge 23 and the arc-shaped filter plate 22. A number of through holes 221 are evenly distributed on the arc-shaped filter plate 22; a matching oil outlet cavity 25 is formed between the arc-shaped filter plate 22 and the bottom of the filtration tank 21. The holes on the arc-shaped filter net 24 are smaller than the diameter of the through holes 221.

[0029] The extrusion component 3 includes a rotating shaft 31 arranged above the arc-shaped filter sponge 23, an extrusion cam 32 fixedly arranged on the rotating shaft 31, and a driving motor 33 connected to the rotating shaft 31; an extrusion section 321 and a cleaning section 322 are arranged on the outer side of the extrusion cam 32; the diameter of the extrusion section 321 is larger than that of the cleaning section 322, and a cleaning brush 323 is arranged on the outer surface of the cleaning section 322; the distance from the axis of the rotating shaft 31 to the surface of the arc-shaped filter sponge 23 is D, the rotation radius of the extrusion section 321 is larger than D, and the rotation radius of the cleaning section 322 is less than or equal to D.

[0030] An oil outlet 42 is arranged at the bottom of the oil storage barrel 4, the oil outlet 42 is communicated with an oil delivery pipe 43, and the output end of the oil delivery pipe 43 is arranged above the arc-shaped filter sponge 23.

[0031] In this embodiment, the gardenia essential oil to be purified is stored in the oil storage barrel 4. The gardenia essential oil flows from the oil outlet 42 at the bottom through the oil pipeline 43 and then reaches the arc-shaped filter sponge 23. After being absorbed by the arc-shaped filter sponge 23, the impurities in the gardenia essential oil remain on the upper surface of the arc-shaped filter sponge 23. At the same time, the driving motor 33 rotates to drive the rotating shaft 31 to rotate, and the rotating shaft 31 drives the extrusion cam 32 to rotate. When the extrusion section 321 on the extrusion cam 32 passes by the arc-shaped filter sponge 23, the extrusion section 321 will squeeze the arc-shaped filter sponge 23, thereby squeezing out the gardenia essential oil in the arc-shaped filter sponge 23. After the squeezed-out gardenia essential oil passes through the arc-shaped filter net 24, it passes through the perforation 221 of the arc-shaped filter plate 22 and drips into the oil outlet cavity 25, and then flows out of the oil outlet cavity 25 for further processing. After the extrusion section 321 squeezes the arc-shaped filter sponge 23, the amount of essential oil in the arc-shaped filter sponge 23 decreases at this time. Therefore, when the new gardenia essential oil flows above the arc-shaped filter sponge 23, it will be quickly absorbed by the arc-shaped filter sponge 23, and the impurities therein (such as dust and solid particles) will fall above the arc-shaped filter sponge 23. When the cleaning section 322 passes by the arc-shaped filter sponge 23, the cleaning brush 323 on the cleaning section 322 will clean the impurities above the arc-shaped filter sponge 23 to prevent the impurities from accumulating above the arc-shaped filter sponge 23.

[0032] Therefore, when filtering the gardenia essential oil in this application, the initial filtration is achieved through the arc-shaped filter sponge 23, and most of the impurities are filtered on the surface of the arc-shaped filter sponge 23, which can effectively reduce the blockage of impurities on the surface of the arc-shaped filter net 24 and extend the service life of the arc-shaped filter net 24. Moreover, through the cooperation of the extrusion cam 32 and the arc-shaped filter sponge 23, the filtration efficiency of the gardenia essential oil can be improved, and at the same time, the impurities on the surface of the arc-shaped filter sponge 23 can be cleaned.

[0033] In one embodiment, the cleaning brushes 323 are arranged on the outer surface of the cleaning section 322 along the direction of the rotating shaft 31.

[0034] In one embodiment, a layer of filter paper can be placed above the arc-shaped filter net 24 to improve the filtration effect, or the arc-shaped filter net 24 can be replaced with filter paper. In addition, a box door is provided on the side wall of the filter box 1 to facilitate the inspection of the structure inside the filter box 1.

[0035] In one embodiment, an oil inlet groove 211 is provided on one side of the filtering tank 21, and the outlet of the oil delivery pipe 43 is communicated with the oil inlet groove 211; a diversion groove 231 communicated with the oil inlet groove 211 is provided at one end of the arc-shaped filtering sponge 23, and the length direction of the diversion groove 231 is perpendicular to the rotation shaft 31. After the gardenia essential oil in the oil outlet cavity 25 flows out from the oil delivery pipe 43, it flows into the oil inlet groove 211, then flows from the oil inlet groove 211 into the diversion groove 231, and finally the gardenia essential oil is absorbed by the arc-shaped filtering sponge 23 in the diversion groove 231.

[0036] In addition, in order to enable the arc-shaped filtering sponge 23 to absorb the gardenia essential oil evenly, in this application, the oil inlet groove 211 is arranged at the middle position of the filtering tank 21. Correspondingly, the diversion groove 231 is also arranged at the middle position of the arc-shaped filtering sponge 23.

[0037] In one embodiment, a dust collecting groove 232 is provided at one end of the arc-shaped filtering sponge 23 away from the diversion groove 231, and the length direction of the dust collecting groove 232 is parallel to the rotation shaft 31; an ash outlet groove 212 communicated with the dust collecting groove 232 is provided on the side wall of the filtering tank 21. After the cleaning section 322 finishes cleaning the surface of the arc-shaped filtering sponge 23, the impurities to be cleaned can accumulate in the dust collecting groove 232. Therefore, after the equipment works for a period of time, it is necessary to regularly clean the impurities in the dust collecting groove 232 through the ash outlet groove 212. Specifically, a small rake can be used to clean the impurities in the dust collecting groove 232.

[0038] In one embodiment, the bottom of the filtering tank 21 is also formed into an arc shape. The arc-shaped filtering tank 21 can gather the purified essential oil at the bottom of the arc-shaped filtering tank 21, which is convenient for discharging the filtered gardenia essential oil. An oil outlet pipe 251 communicated with the oil outlet cavity 25 is provided at the bottom of the filtering tank 21.

[0039] In one embodiment, support plates 26 are provided on both sides of the filtering tank 21, support bearings are provided on the support plates 26, and the rotation shaft 31 is arranged on the support bearings of the two support plates 26; the extrusion cam 32 is arranged between the two support bearings.

[0040] The support plates 26 on both sides of the filtering tank 21 can support the rotation shaft 31, so that the rotation shaft 31 can be stably arranged above the filtering tank 21.

[0041] In one embodiment, in order to reduce the pollution of the essential oil in the filtering tank 21 by dust, a closed cover 5 is provided above the filtering tank 21, and slots 51 matched with the two support plates 26 are provided on both sides of the closed cover 5. The slots 51 can cooperate with the support plates 26 to jointly cover above the filtering tank 21, so as to form a filtering space isolated from the outside world in the closed cover 5 and prevent impurities such as dust from polluting the gardenia essential oil.

[0042] In one embodiment, the bottom of the essential oil barrel 4 is configured to be conical, and the oil outlet 42 is provided at the bottom of the cone. By setting the oil outlet 42 at the bottom of the cone, the essential oil in the essential oil barrel 4 can flow out better.

[0043] The working principle of this embodiment is as follows: The gardenia essential oil to be purified is stored in the essential oil barrel 4. The gardenia essential oil flows through the oil delivery pipe 43 from the bottom oil outlet 42 and then reaches the arc-shaped filter sponge 23. After being absorbed by the arc-shaped filter sponge 23, the impurities in the gardenia essential oil remain on the upper surface of the arc-shaped filter sponge 23. At the same time, the driving motor 33 rotates to drive the rotating shaft 31 to rotate, and the rotating shaft 31 drives the extrusion cam 32 to rotate. When the extrusion section 321 on the extrusion cam 32 passes through the arc-shaped filter sponge 23, the extrusion section 321 will squeeze the arc-shaped filter sponge 23, thereby squeezing out the gardenia essential oil in the arc-shaped filter sponge 23. After being squeezed out, the gardenia essential oil passes through the arc-shaped filter net 24 and then passes through the perforation 221 of the arc-shaped filter plate 22 and drips into the oil outlet cavity 25, and then flows out from the oil outlet cavity 25 for further processing. After the extrusion section 321 squeezes the arc-shaped filter sponge 23, the amount of essential oil in the arc-shaped filter sponge 23 at this time decreases. Therefore, when the essential oil flows above the arc-shaped filter sponge 23, it will be quickly absorbed by the arc-shaped filter sponge 23, and the impurities therein (such as dust and solid particles) will fall on the upper surface of the arc-shaped filter sponge 23. When the cleaning section 322 passes through the arc-shaped filter sponge 23, the cleaning brush 323 on the cleaning section 322 will sweep the impurities above the arc-shaped filter sponge 23 into the dust collecting groove 232 to prevent the impurities from accumulating above the arc-shaped filter sponge 23.

[0044] Therefore, when filtering the gardenia essential oil in this application, the primary filtration is achieved through the arc-shaped filter sponge 23, and most of the impurities are filtered on the surface of the arc-shaped filter sponge 23, thereby effectively reducing the blockage of impurities on the surface of the arc-shaped filter net 24, extending the service life of the arc-shaped filter net 24, and improving the filtration and purification efficiency of the gardenia essential oil. Moreover, the extrusion section 321 can squeeze the arc-shaped filter sponge 23 to improve the filtration rate of the essential oil. At the same time, by cleaning the surface of the arc-shaped filter sponge 23 through the cleaning section 322, it can prevent the impurities from accumulating on the surface of the arc-shaped filter sponge 23. Therefore, through the cooperation of the extrusion cam 32 and the arc-shaped filter sponge 23, the filtration efficiency of the gardenia essential oil can be improved, and at the same time, the impurities on the surface of the arc-shaped filter sponge 23 can be cleaned.

[0045] Embodiment 2: Refer to Figure 6 and Figure 7As shown, the structure in this embodiment is similar to that in Embodiment 1. The difference is that an installation groove 324 is provided on the outer surface of the extrusion section 321, and a plurality of extrusion rollers 325 are rotatably arranged in the installation groove 324. The axial direction of the extrusion rollers 325 is parallel to the rotation axis 31, and both ends of the extrusion rollers 325 are rotatably arranged at both ends of the installation groove 324. The number of the extrusion rollers 325 corresponds to the arc length of the cleaning section 322. In this embodiment, one extrusion roller 325 is provided on the outer side wall of the extrusion section 321.

[0046] Thus, when the extrusion section 321 passes through the arc-shaped filter sponge 23, the extrusion rollers 325 can rotate along the surface of the arc-shaped filter sponge 23, thereby reducing the friction between the cleaning section 322 and the arc-shaped filter sponge 23.

[0047] The above-described embodiments are only preferred solutions of the present invention, and do not impose any form of limitation on the present invention. There are other variations and modifications without exceeding the technical solutions recorded in the claims.
