Description

Technical Field

[0001] The present invention relates to the technical field of cosmetic production, and in particular to a purification device for processing cosmetic raw materials and related processes. Background Art

[0002] In the production process of cosmetics, in order to improve the efficacy of cosmetics, various types of vegetable oils are usually added to the cosmetics, such as avocado oil, olive oil, etc. The extraction method of these vegetable oils is usually to use an oil press to press the processed pulp, so as to squeeze out the oil in the pulp. The oil press is usually used to extract edible oil. For cosmetics, more attention is paid to the retention of active ingredients such as vitamins in vegetable oils. During the oil pressing process of the existing oil press, the squeezed oil is usually exposed to the air, which easily causes the vitamins in the vegetable oil to be oxidized in the air, thereby reducing the active ingredients in the vegetable oil, thereby reducing the efficacy of the vegetable oil in cosmetics. In addition, in order to retain the nutrients in the oil, the cold pressing method is usually used to squeeze the oil. However, when the cold pressing method is used, heat will still inevitably continue to be generated during the oil pressing process, thereby increasing the temperature of the squeezed vegetable oil, thereby causing the active ingredients in the vegetable oil to be destroyed by heat, further reducing the efficacy of the vegetable oil. Summary of the invention

[0003] In order to overcome the disadvantages that in cosmetic production, although cold pressing is used to press vegetable oils to retain active ingredients such as vitamins therein, the oils are easily oxidized when exposed to the air during the pressing process, and cold pressing still generates heat, causing the temperature to rise, which will reduce the active ingredients of the vegetable oils and further affect their efficacy in cosmetics, the present invention provides a purification device for processing cosmetic raw materials and related processes.

The temperature inside the oil cake is lowered by low-temperature nitrogen, thereby preventing the vitamin components in the oil from being destroyed due to excessive temperature, thus ensuring the quality of the oil. When the oil is discharged from the oil outlet tank, the low-temperature nitrogen in the closed chamber is blown to the oil, thereby further cooling the oil, keeping the oil in a low-temperature state for storage, which is convenient for the preservation of the effective components in the oil. Compared with conventional oil pressing devices, after the oil pressing is completed, the oil outlet tank is cleaned by scrapers and air blowing, eliminating the workload of manual cleaning of the oil outlet tank. In addition, self-cleaning can be achieved after each oil pressing is completed, avoiding the pulp from remaining in the oil outlet tank for a long time, ensuring that the quality of the oil is not affected.

[0022] It also includes a scraper 208 ; a plurality of scrapers 208 arranged in a ring shape are provided on the bottom plate 207 ; each scraper 208 corresponds to an adjacent oil outlet groove 3001 .

[0023] Furthermore, in order to improve the cleaning effect of the pulp in the oil outlet groove 3001 , the positions of all the exhaust holes 5001 correspond to the adjacent oil outlet grooves 3001 .

[0024] The following is a detailed description of the extraction process of plant oils required in cosmetics: Before extracting vegetable oil, first place the corresponding plant pulp required for extracting vegetable oil in the storage chamber 3002 inside the cylinder 3, then control the first driving member 2 to drive the pressing block 2001 to move downward, so that the pressing block 2001 fits the inner wall of the cylinder 3, and then squeezes the plant pulp in the storage chamber 3002. The pressing block 2001 continues to squeeze the plant pulp, so that the oil in the plant pulp is squeezed out, and the oil seeps out to the outer wall of the cylinder 3 through the oil outlet groove 3001, flows downward along the outer wall of the cylinder 3, and then flows into the oil collecting groove 6001, and then the oil is transferred to the external storage tank through the oil drain valve on the retaining ring 6 for sealed storage. The pulp forms oil cakes during the continuous squeezing process, thereby realizing the extraction and collection of vegetable oil. During the extraction, the squeezed oil is in continuous contact with the outside air, which causes the vitamins and other natural active ingredients in the oil to be oxidized, the quality of the oil is reduced, and the efficacy of the cosmetics is reduced. Therefore, before squeezing the oil, the second driving member 201 is controlled to drive the protective cover 4 and the air ring 5 to move downward until the lower end of the air ring 5 is in contact with the upper end of the baffle ring 6, and the air ring 5 stops moving. At the same time, the pressing block 2001 is controlled to drive the fixed plate 202, the round rod 203 and the bottom plate 207 to move downward, so that the bottom plate 207 is inserted into the storage cavity 3002, and there is space between the pressing block 2001 and the cylinder 3, and then the plant pulp is placed on the bottom plate 207 in the storage cavity 3002 to complete the placement of the pulp, and then the pressing block 2001 is controlled to continue to move so that the bottom plate 207 is inserted into the storage cavity 3002. The plate 207 is fitted with the bottom of the storage cavity 3002, and the bottom of the round rod 203 is fitted with the upper end of the exhaust pipe 206. At this time, the bottom of the round rod 203 cannot move downward any further, and the inside of the round rod 203 is connected with the exhaust pipe 206, and the pressing block 2001 is controlled to move downward any further, so that the fixed plate 202, the round rod 203 and the pressing block 2001 slide relative to each other, until the pressing block 2001 fits with the inner wall of the cylinder 3 and stops moving. At this time, a closed cavity is formed between the cylinder 3, the protective cover 4, the air ring 5 and the retaining ring 6. At this time, the air inlet end of the external air supply device is connected with the communicating vessel 205, and the air outlet end is connected with the air ring 5. Then, the air pump in the external air supply device is controlled to start pumping air, so that the gas in the closed cavity passes through the communicating pipe 204, the cavity 2002, the round rod 203 in sequence. 203, the exhaust pipe 206 and the communicating vessel 205, and then the gas in the closed cavity is discharged through the external gas supply device, so as to ensure that the oxygen in the closed cavity is discharged, and then the nitrogen is transported into the gas ring 5 by controlling the gas outlet end of the external gas supply device, so that the nitrogen enters the closed cavity through the exhaust hole 5001, and then the nitrogen flows upward and enters the cavity 2002 through the communicating pipe 204, and then the nitrogen passes through the inside of the round rod 203 and the exhaust pipe 206 in turn, and finally merges into the communicating vessel 205, and flows back from the communicating vessel 205 to the external gas supply pipeline, so that the closed cavity is filled with nitrogen, and then the pressing block 2001 is controlled to continue to move downward, and the oil cake is located between the bottom plate 207 and the pressing block 2001, and the oil cake is continuously squeezed by the pressing block 2001,The oil is extracted and collected. Compared with the conventional oil pressing method, during the oil pressing process, the closed cavity formed by the cylinder 3, the protective cover 4, the air ring 5 and the baffle ring 6 prevents the outside air from contacting the oil, thereby preventing the vitamin components in the oil from being oxidized by the outside air, ensuring the quality of the oil, and thus improving the efficacy of the cosmetics. In addition, before the oil is pressed, the oxygen in the closed cavity is discharged, and then the nitrogen is filled in the closed cavity to prevent the vitamin components in the oil from being oxidized by the oxygen in the closed cavity, thereby further improving the quality of the oil.

[0025] On this basis, when the pressing block 2001 continues to squeeze the oil cake, the pressure applied by the pressing block 2001 overcomes the internal resistance of the oil cake to do work, and this part of energy is converted into heat energy inside the oil cake, which causes the temperature of the oil cake to rise, and then causes the temperature of the oil in the oil cake to be too high, causing the vitamin components in the oil to be destroyed due to heat, thereby reducing the quality of the oil. For this reason, the low-temperature nitrogen is delivered to the air ring 5 by controlling the external air supply device, so that the low-temperature nitrogen passes through the closed cavity, the cavity 2002, the round rod 203, the exhaust pipe 206 and the connecting vessel 205 in sequence, so that the round rod 203 is cooled by the low-temperature nitrogen. Since the round rod 203 runs through the inside of the oil cake at this time, and the round rod 203 is configured to adopt a heat-conducting metal material, the inside of the oil cake is cooled by the round rod 203, so that the temperature inside the oil cake is reduced, thereby avoiding the destruction of the vitamin components in the oil due to excessive temperature, ensuring the quality of the oil, and when the oil is discharged from the oil outlet groove 3001 , the low-temperature nitrogen in the closed cavity is blown toward the oil, thereby further cooling the oil, so that the oil is kept in a low-temperature state for storage, which is convenient for the preservation of the effective ingredients in the oil. At the same time, when the pressing block 2001 continues to squeeze the oil cake, compared with the outside of the oil cake, the distance between the oil inside the oil cake and the oil outlet groove 3001 is farther, so the oil inside the oil cake is more difficult to be squeezed out. For this reason, a plurality of first-row oil grooves 20301 are opened on the round rod 203, so that the oil inside the oil cake can enter the first-row oil grooves 20301. The oil flows downward through the first-row oil grooves 20301 to the second-row oil grooves 20701 on the bottom plate 207, and then flows through the second-row oil grooves 20701 to the connection between the bottom plate 207 and the inner wall of the cylinder 3, so that the oil is discharged from the oil outlet groove 3001. The outflow of the oil inside the oil cake is guided by the first-row oil grooves 20301 and the second-row oil grooves 20701, thereby improving the oil yield of the plant pulp.

[0026] Further, after the pressing block 2001 completes squeezing the oil cake, the first driving member 2 is then controlled to drive the pressing block 2001 to continuously move upward, drive the round rod 203 and the bottom plate 207 to move upward, and thus drive the oil cake to move upward until the oil cake is separated from the cylinder 3, so that after the oil pressing is completed, the oil cake is synchronously taken out of the cylinder 3. On this basis, by setting the bottom plate 207 to be clamped on the round rod 203, when the oil cake is separated from the cylinder 3, it is only necessary to manually press the bottom plate 207 downward to make the bottom plate 207 and the round rod 2 03 is separated, and then the oil cake is pressed downward to move the oil cake downward and separate from the round rod 203, completing the collection of the oil cake, and then the bottom plate 207 is re-connected to the round rod 203, so as to achieve rapid separation and collection of the oil cake, which is convenient for the subsequent placement of the pulp, and by separating the bottom plate 207 from the round rod 203, it is convenient to manually clean the first row of oil grooves 20301 and the second row of oil grooves 20701 separately, ensuring that the connection between the bottom plate 207 and the round rod 203 can be fully cleaned, thereby improving the cleaning effect.

[0027] During the oil pressing process, part of the plant pulp will be stuck in the oil outlet groove 3001, thereby causing the oil outlet groove 3001 to be blocked. Therefore, when the pressing block 2001 drives the bottom plate 207 to move downward and fit the bottom of the storage chamber 3002, it simultaneously drives the scraper 208 to move downward so that the scraper 208 is located at the bottom of the corresponding oil outlet groove 3001. When the oil pressing is completed, the bottom plate 207 moves upward, driving the scraper 208 to scrape the oil outlet groove 3001 upward, thereby scraping out the pulp stuck in the oil outlet groove 3001 to avoid the oil outlet groove 3001 being blocked. On this basis, the external air supply device is controlled to deliver nitrogen to the air ring 5. Since all the exhaust holes 5001 are opened The directions are all set to be toward the center of the cylinder 3, so that the transported nitrogen is blown vertically to the oil outlet groove 3001, and then the second driving member 201 is controlled to drive the protective cover 4 and the air ring 5 to move upward, so that the nitrogen is blown to the oil outlet groove 3001 from bottom to top, so that the pulp remaining in the oil outlet groove 3001 is cleaned by the blown nitrogen. Compared with the conventional oil pressing device, after the oil pressing is completed, the oil outlet groove 3001 is cleaned by the scraper 208 and the air blowing, eliminating the workload of manual cleaning of the oil outlet groove 3001, and self-cleaning can be achieved after each oil pressing is completed, so as to avoid the pulp remaining in the oil outlet groove 3001 for a long time, and ensure that the quality of the oil is not affected.

[0028] Example 2 On the basis of Example 1, Figure 1 and Figure 8-Figure 9As shown, a filtering system is also included, which includes a support plate 301, a filter screen 302 and a scraper ring 303; two left-right symmetrical support plates 301 are connected under the air ring 5 through a spring; the two support plates 301 are fixedly connected with a filter screen 302; the filter screen 302 is sleeved on the cylinder 3; the scraper ring 303 is fixedly connected to the filter screen 302; the scraper ring 303 is slidably connected to the outer wall of the cylinder 3.

[0029] Furthermore, in order to improve the efficiency of filtering grease, a concave arc surface 30301 is provided on the scraper ring 303.

[0030] Furthermore, in order to improve the cooling effect of nitrogen on the grease, a slope 30302 is provided on the scraper ring 303 .

[0031] During the oil pressing process, some impurities such as fibers in the pulp are easily squeezed out and flow into the oil collecting tank 6001 together with the oil. Compared with pure oil, impurities such as fibers in the pulp are easy to deteriorate, thereby easily reducing the quality of the oil. Therefore, it is necessary to separate the fiber impurities in the oil. For this purpose, when the second driving member 201 drives the protective cover 4 and the air ring 5 to move downward, it simultaneously drives the support plate 301 to move downward, thereby driving the filter 302 and the scraper ring 303 to move downward on the cylinder 3, so that the support plate 301 first fits with the baffle ring 6. As the protective cover 4 and the air ring 5 continue to move downward, the spring between the support plate 301 and the air ring 5 is compressed until the air ring 5 fits with the baffle ring 6. At this time, the filter 302 is located between the air ring 5 and the baffle ring 6, so that the fiber and other impurities in the oil are intercepted by the filter 302, ensuring that the oil flowing into the oil collecting tank 6001 does not contain impurities such as pulp fibers, thereby improving the quality of the oil.

[0032] On this basis, when the air ring 5 is fitted with the retaining ring 6, the junction of the concave arc surface 30301 and the inclined surface 30302 is directly opposite to the exhaust hole 5001. When nitrogen is discharged from the exhaust hole 5001, the air flow is blown to the concave arc surface 30301 and the inclined surface 30302 respectively. At the same time, the grease is discharged from the oil outlet groove 3001 and flows downward along the outer wall of the cylinder 3 until it flows to the inclined surface 30302, and then falls from the lower edge of the inclined surface 30302 to the oil collecting groove 6001. In this process, compared with nitrogen blowing vertically to the grease surface, when nitrogen blows to the grease on the inclined surface 30302, the contact area with the grease is larger, thereby improving the cooling effect of nitrogen on the grease. On this basis, when the grease is squeezed out and passes through the filter 302, due to the viscosity of the grease, the speed at which the grease passes through the filter 302 decreases, thereby reducing the efficiency of filtering the grease. For this reason, by blowing nitrogen The concave arc surface 30301 guides the nitrogen to flow downward through the concave arc surface 30301, so that the nitrogen is blown to the grease on the surface of the filter screen 302, thereby pushing the grease to flow downward, accelerating the speed of the grease passing through the filter screen 302, and improving the efficiency of filtering the grease. When the oil pressing is completed, the grease in the oil collecting tank 6001 is first discharged through the oil discharge valve, and then the protective cover 4 and the air ring 5 are driven to move upward through the second driving member 201, thereby driving the support plate 301, the filter screen 302 and the scraper ring 303 to move upward. At this time, the spring between the support plate 301 and the air ring 5 is reset, so that the filter screen 302 and the scraper ring 303 move downward relative to the air ring 5, so that the nitrogen in the air ring 5 is blown to the oil outlet tank 3001 through the exhaust hole 5001. At the same time, when the scraper ring 303 moves upward, it scrapes with the outer wall of the cylinder 3, so that the outer wall of the cylinder 3 is cleaned synchronously, thereby improving the cleaning efficiency.
