Description

Technical Field

[0001] The invention relates to the technical field of tea oil processing, in particular to a tea oil processing and purification system. Background Art

[0002] Tea oil is the common name for camellia oil, also known as camellia oil and camellia seed oil. It is a pure natural high-grade edible vegetable oil extracted from the mature seeds of common camellia oil plants of the Theaceae family. It is golden or light yellow in color, pure in quality, clear and transparent, with a fresh and fragrant smell and a pure taste. During the production and processing of tea oil, a small amount of residue and other sediments remain inside. In order to improve the clarity of tea oil, the sediments contained in the tea oil need to be filtered out.

[0003] When filtering out the sediment in the tea oil, an oil residue separator is used. The existing oil residue separator generally filters the tea oil by centrifugation. Since the oil residue separator swings the tea oil by rotating the inner tank, the inner tank intercepts the oil residue, and the tea oil enters the outer tank of the separator through the filter holes opened on the inner tank, thereby achieving the purpose of separating the tea oil and the oil residue. However, since the tea oil itself is sticky, the oil residue with tea oil is easy to adhere to the inner wall of the inner tank, resulting in the filter holes of the inner tank being blocked, and the flow rate of tea oil entering the outer tank is reduced, making the filtering effect of the centrifuge worse and worse, affecting the efficiency of tea oil processing and purification.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] Embodiment 1: like Figures 1 to 3 As shown, a tea oil processing and purification system includes a support frame 1, on which an oil residue separator 2 is installed, and the oil residue separator 2 includes: The outer tank body 3 is fixedly mounted on the support frame 1. The support frame 1 is provided with a driving motor 31 on the side of the outer tank body 3. A slag outlet 32 ​​is provided at the center of the bottom surface of the outer tank body 3. A cover plate 33 is hinged on the slag outlet 32. One side of the bottom surface of the outer tank body 3 is connected to an oil outlet pipe 34. The filter tank 4 is rotatably mounted at the center of the outer tank body 3, the filter tank 4 is slidably connected to the top wall and the bottom wall of the outer tank body 3, the side wall of the filter tank 4 is evenly provided with filter holes, the upper end of the filter tank 4 is rotatably mounted with an oil inlet 41, and the oil inlet 41 is fixedly connected to the outer tank body 3 through fixing rods 42 symmetrically arranged on both sides; The driving shaft 5 is connected to the driving motor 31. A first gear 51 is arranged on the driving shaft 5. A second gear 52 is fixedly sleeved on the upper end of the filter tank 4. The second gear 52 is at the same height as the first gear 51. Sprockets 53 are synchronously nested on the first gear 51 and the second gear 52; The fixing bracket 6 is arranged on the upper end surface of the outer tank body 3, the fixing bracket 6 is U-shaped, and a driving rod 61 is rotatably installed in the middle of the end surface of the fixing bracket 6 facing the oil inlet 41, and the lower end of the driving rod 61 is inserted into the interior of the filter tank 4, and a rotating unit is arranged on the driving rod 61.

[0020] The scraper 7 is slidably mounted on the inner wall of the filter tank 4, and a connecting ring 71 is slidably sleeved on the position of the driving rod 61 near the scraper 7. A plurality of connecting rods 72 are evenly mounted on the outer wall of the connecting ring 71. The connecting ring 71 and the scraper 7 are connected via the connecting rod 72. A spiral groove is provided on the driving rod 61. The inner wall of the connecting ring 71 is slidably connected in the spiral groove. Two fixed blocks 75 are symmetrically arranged on the side wall of the slag outlet 32. A limiting shaft 76 is fixedly mounted on the fixed block 75. The upper part of the limiting shaft 76 is inclined. The upper end of the limiting shaft 76 is slidably connected to the inner wall of the filter tank 4. A corresponding slide groove is provided on the filter tank 4. The limiting shaft 76 passes through the connecting ring 71 and is slidably connected to the connecting ring 71.

[0021] Specifically, the rotating unit includes: a driving rod 61 is located above the oil inlet 41 and is fixedly sleeved with a third gear 62; two supporting columns 63 are symmetrically rotatably installed on the upper end surface of the outer tank body 3; a first sector-shaped gear ring 64 and a second sector-shaped gear ring 65 are respectively provided at the upper ends of the two supporting columns 63; the first sector-shaped gear ring 64 and the second sector-shaped gear ring 65 are meshed with the third gear 62 in sequence; a first pulley 66 is sleeved on the supporting column 63; a second pulley 67 is fixedly sleeved on the driving shaft 5; the second pulley 67 is located above the first gear 51; a belt 68 is synchronously sleeved on the first pulley 66 and the second pulley 67.

[0022] The specific working process is as follows: when it is necessary to improve the clarity of tea oil and remove the sediment in the tea oil, the tea oil is injected into the purification system. When the tea oil flows to the oil-residue separator 2, the tea oil will flow into the filter tank 4 from the oil inlet 41, and the drive motor 31 is started. The drive motor 31 can drive the drive shaft 5 to rotate, and the drive shaft 5 drives the No. 1 gear 51 to rotate synchronously, the No. 1 gear 51 drives the sprocket 53 to rotate synchronously, the sprocket 53 drives the No. 2 gear 52 to rotate synchronously, and the No. 2 gear 52 drives the filter tank 4 to rotate synchronously. The tea oil in the filter tank 4 rotates synchronously along the rotation direction of the filter tank 4. Step rolling, since the filter tank 4 rotates around its own central axis, the tea oil in the filter tank 4 will roll toward the inner wall of the filter tank 4, so that the tea oil can flow out of the filter tank 4 from the filter holes on the side walls of the filter tank 4, and then enter the outer tank body 3, and finally flow out from the oil outlet pipe 34 at the bottom of the outer tank body 3. The size of the sediment contained in the tea oil is larger than the diameter of the filter hole, so that the sediment will gather on the inner wall of the filter tank 4 and cannot enter the outer tank body 3, so that the tea oil and the sediment can be separated, thereby achieving the purpose of filtering the sediment in the tea oil; When the driving shaft 5 drives the No. 1 gear 51 to rotate, the driving shaft 5 also drives the two No. 2 pulleys 67 to rotate synchronously, the No. 2 pulley 67 drives the corresponding belt 68 to rotate synchronously, the belt 68 drives the No. 1 pulley 66 to rotate synchronously, the No. 1 pulley 66 drives the supporting column 63 to rotate synchronously, the supporting column 63 drives the corresponding No. 1 sector gear ring 64 and No. 2 sector gear ring 65 to rotate synchronously, when the No. 1 sector gear ring 64 rotates to mesh with the No. 3 gear 62, the No. 1 sector gear ring 64 can drive the No. 3 gear 62 to rotate, and the No. 3 gear 62 drives the driving rod 61 to rotate synchronously. Since the limiting shaft 76 runs through the setting of the connecting ring 71, the limiting shaft 76 can limit the connecting ring 71 when the driving rod 61 drives the connecting ring 71 to move, so that the driving rod 61 can drive the connecting ring 71 to move downward synchronously according to the principle of the screw slider when rotating, and the connecting ring 71 drives the three connecting rods 72 to move synchronously. The connecting rod 72 drives the scraper 7 to move synchronously. When moving, the scraper 7 can scrape off the tea oil sediment attached to the inner wall of the filter tank 4, so that the sediment will move downward and finally fall into the slag outlet 32 ​​for collection. When the oil-residue separator 2 is shut down and the sediment needs to be cleaned, the cover plate 33 at the bottom of the outer tank body 3 can be opened for cleaning; because the driving motor 31 first drives the filter tank 4 to rotate through the sprocket 53, the scraper 7 has not started to move up and down at this time. When the equipment does not work for a period of time, due to the viscosity of the tea oil itself, the scraper 7 may stick to the filter tank 4, so that when the filter tank 4 rotates, the filter tank 4 and the scraper 7 will rotate relative to each other, so that the scraper 7 originally bonded to the filter tank 4 can be displaced, so that the scraper 7 and the filter tank 4 are no longer bonded, ensuring that the subsequent scraper 7 can move up and down normally, thereby further improving the cleaning effect of the scraper 7 on the inner wall of the filter tank 4.

[0023] When the first sector gear ring 64 rotates to no longer mesh with the third gear 62, the scraper 7 has moved to the lower end height position of the spiral groove 73, and the second sector gear ring 65 just rotates to mesh with the third gear 62, the second sector gear ring 65 drives the third gear 62 to rotate in the opposite direction, and the third gear 62 drives the driving rod 61 to rotate in the opposite direction synchronously, and the driving rod 61 drives the connecting ring 71 to move upward synchronously through the screw slider principle, and the connecting ring 71 drives the scraper 7 to move upward synchronously through the connecting rod 72 until it moves to the upper end height position of the spiral groove 73, and the scraper 7 realizes a lifting reciprocating motion. The sector gear ring 65 rotates to a position where it is no longer meshed with the gear 62 No. 3, and the sector gear ring 64 rotates again to mesh with the gear 62 No. 3, thereby achieving the purpose of scraping off the sediment attached to the inner wall of the filter tank 4 by driving the scraper 7 to move up and down, preventing the sediment from accumulating on the inner wall of the filter tank 4 and blocking the filter holes, resulting in the tea oil being unable to enter the outer tank body 3 for extraction, thereby ensuring the filtering effect of the oil residue separator 2, so that the oil residue separator 2 of the purification system can simultaneously filter and clean the tea oil sediment, thereby ensuring that the extracted tea oil is clean and pure, and improving the quality of the tea oil.

[0024] Embodiment 2: like Figure 3 and Figure 4 As shown, a slag storage groove 43 is provided at the lower end of the filter tank 4, and the slag storage groove 43 is concentrically arranged with the slag outlet 32, and the inner diameter of the slag storage groove 43 is equal to the slag outlet 32, and the side wall of the filter tank 4 near the upper part of the slag storage groove 43 is arranged as an inclined surface, and the inclined surface and the oil inlet 41 are both inverted cones; the lower part of the connecting ring 71 is provided with an extrusion head 711 which is inclined from the middle to the surrounding areas in a conical shape, and the diameter of the extrusion head 711 is equal to the inner diameter of the slag storage groove 43, and the driving rod 61 passes through the center of the extrusion head 711.

[0025] The specific working process is as follows: when the driving rod 61 rotates and drives the connecting ring 71 to move downward through the spiral groove 73 and the limit block 74, the extrusion head 711 on the connecting ring 71 moves downward synchronously, and when the connecting ring 71 moves to a position close to the lower end of the spiral groove 73, the extrusion head 711 begins to enter the residue storage groove 43. Since the diameter of the extrusion head 711 is equal to the inner diameter of the residue storage groove 43, the extrusion head 711 will squeeze the sediment in the residue storage groove 43 along the groove wall of the residue storage groove 43, so that the tea oil originally attached to the sediment will be squeezed out by the extrusion head. As the extrusion head 711 continues to move toward the bottom of the residue storage groove 43, since the side wall of the residue storage groove 43 is provided with filter holes, at this time, the tea oil squeezed out from the sediment will flow toward the side wall of the residue storage groove 43, and finally from the residue storage groove The tea oil flows out from the filter hole 43 and enters the outer tank body 3 for collection. By arranging the extrusion head 711, the sediment in the residue storage tank 43 can be squeezed when the connecting rod 72 descends, so that the tea oil accumulated in the sediment can also be collected, thereby increasing the extraction amount of the tea oil. Since the extrusion head 711 is located at the center of the filter tank 4, when the tea oil enters the filter tank 4, the tea oil may drip on the upper end surface of the extrusion head 711. By setting the upper end surface of the extrusion head 711 to be a cone inclined from the center to the surrounding areas, the tea oil can flow along the inclined surface of the extrusion head 711 to the edge of the extrusion head 711, and finally flow from the extrusion head 711 to the side wall of the filter tank 4 or the residue storage tank 43, so that the tea oil will not accumulate on the extrusion head 711, thereby ensuring the normal extraction and collection of the tea oil.

[0026] Embodiment three: like Figure 5 As shown, a secondary filter plate 44 is fixedly installed inside the side wall of the filter tank 4. The secondary filter plate 44 is arranged in an annular shape, and the filter hole size of the secondary filter plate 44 is smaller than the filter hole of the filter tank 4.

[0027] The specific working process is as follows: Since tea oils of different purities contain precipitates of different sizes, under normal circumstances, the filter tank 4 can filter the tea oil with lower purity, so that the larger precipitates can remain in the filter tank 4 and will not enter the outer tank body 3. When the tea oil with higher purity needs to be filtered, since the precipitates in the high-purity tea oil are smaller, the filter holes of the filter tank 4 cannot achieve the filtering effect. At this time, the filter hole size of the secondary filter plate 44 inside the filter tank 4 is smaller than the filter holes on the filter tank 4, so that the secondary filter plate 44 can filter the precipitates in the high-purity tea oil, so that the oil residue separator 2 can achieve the purpose of filtering when facing tea oils of different purities, thereby improving the applicability of the oil residue separator 2 when filtering tea oils of different purities.

[0028] Embodiment 4: like Figure 2 and Figure 5As shown, a brush 8 is provided at a position of the outer tank body 3 near the filter tank 4, and both ends of the brush 8 are fixedly mounted on the inner wall of the outer tank body 3. The shape of the brush 8 is adapted to the side wall of the filter tank 4, and the bristles of the brush 8 can extend into the filter holes of the filter tank 4 and the secondary filter plate 44, and the bristles can contact the inner walls of the filter holes.

[0029] The specific working process is as follows: when the filter tank 4 is driven by the driving motor 31 to rotate, the brush 8 in contact with the outer wall of the filter tank 4 can be extended into the filter hole on the side wall of the filter tank 4 to scrape the residual sediment in the filter hole, so that the sediment in the filter hole is pushed into the interior of the filter tank 4 by the bristles. Since the shape of the brush 8 is adapted to the side wall of the filter tank 4 and the filter tank 4 is rotating all the time, the filter tank 4 can be scraped in all directions. Since the secondary filter plate 44 is located inside the filter tank 4, the sediment in the filter holes on the filter tank 4 and the secondary filter plate 44 can be cleaned, ensuring that the filter holes will not be blocked by sediment, resulting in the inability of tea oil to flow from the filter holes into the outer tank body 3 for extraction, thereby preventing the filtering effect of the oil residue separator 2 from failing and improving the stability of the filter tank 4 when filtering tea oil.

[0030] Embodiment five: like Figure 3 and Figure 4 As shown, the filter holes on the side wall of the slag storage tank 43 are smaller than the filter holes on the side wall of the filter tank 4.

[0031] The specific working process is as follows: when the extrusion head 711 enters the residue storage tank 43 to extrude the oil residue sediment, the tea oil attached to the sediment will flow out from the inside of the sediment under the action of pressure and space reduction, and then enter the residue storage tank 43, and finally flow out from the filter holes of the residue storage tank 43. The purpose of setting the filter hole size on the side wall of the residue storage tank 43 to be smaller than the filter holes on the side wall of the filter tank 4 is to prevent the sediment from being pressed into the filter holes of the residue storage tank 43 when the extrusion head 711 squeezes the sediment, causing the sediment to block the filter holes or even enter the outer tank body 3 from the filter holes, thereby ensuring that the outer tank body 3 is a clean tea oil extraction chamber without any sediment, thereby improving the stability of the oil residue separator 2 in extracting tea oil.

[0032] Embodiment six: like Figure 6 As shown, the upper and lower end surfaces of the scraper 7 are both arranged as inclined surfaces inclined toward the center of the scraper 7 .

[0033] The specific working process is as follows: when tea oil enters the filter tank 4 from the oil inlet 41, part of the tea oil may drip onto the scraper 7. Since the upper end surface of the scraper 7 is inclined toward the center of the scraper 7, the tea oil will slide off the scraper 7 to prevent the tea oil from accumulating on the scraper 7 and affecting the extraction amount of the tea oil; the purpose of setting the lower end surface of the scraper 7 to be inclined toward the center of the scraper 7 is that when the scraper 7 moves downward, the scraper 7 can scrape the sediment attached to the inner wall of the filter tank 4. Compared with the plane, the inclined end surface is similar to a blade, which has a better scraping effect on the sediment, prevents the sediment from blocking the filter holes of the filter tank 4, and further improves the filtering effect of the filter tank 4.
