Description

Technical Field

[0001] The invention relates to the technical field of microbial oil extraction, in particular to a microalgae oil separation and purification device. Background Art

[0002] Microbial oils, also known as single-cell oils, are oils and other commercially valuable lipids produced by microorganisms such as yeast, mold, bacteria and algae under certain conditions using carbohydrates, hydrocarbons and ordinary oils as carbon sources and nitrogen sources, supplemented by inorganic salts.

[0003] Algae plants have a relatively fast growth rate and strong environmental adaptability. Algae plants can carry out photosynthesis and convert solar energy into bioenergy. This growth environment can produce a large amount of oil in algae plants. Among many algae, Schizochytrium is a marine fungus rich in DHA. The extracted microbial oil contains polyunsaturated fatty acids needed by the human body. Therefore, it has high edible and medicinal properties and higher commercial value.

[0004] However, the existing microalgae oil separation and purification equipment has the following shortcomings: The steps of extracting oil from Schizochytrium microorganisms can be divided into algae culture, algae fermentation, fermentation liquid agglomeration, algae powder preparation, alkali-heat wall breaking, oil-water separation and distillation purification. However, in the oil-water separation stage, the existing equipment gradually forms oil-water stratification as the standing time of the oil and water liquid increases and the density of oil and water is different. The existing method of extracting the oil layer cannot accurately measure the thickness of the oil layer, resulting in a higher water content in the extracted oil, which increases the difficulty of subsequent distillation and purification time.

[0005] Therefore, we propose a microalgae oil separation and purification device to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a microalgae oil separation and purification device, which collects two beams of reflected light at the same time through the separation self-priming mechanism, obtains two optical path offset values, and quickly obtains the accurate distance between the two liquid surface reflection points by the photoelectric detection device, corresponding to the actual height of the oil layer. After the obtained value is fed back to the equipment system, with the assistance of height data, the mechanical transmission component can be flexibly controlled to intermittently lower the liquid inlet end of the oil suction pipe to a specified height range, thereby ensuring that the extracted oil is rarely mixed with external liquid, so as to solve the problems raised by the above-mentioned background technology.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a separation self-priming mechanism, which simultaneously performs alkali thermal wall breaking and oil separation. After the stirring component is pulled away from the alkali solution, the difference in density between the alkali solution and the oil is used to separate the two during the static time. The oil with a smaller density is distributed in the upper layer. The subsequent laser transmitter head can emit a vertical laser beam into the oil. By using the difference in light transmittance and density between the two, a single beam of light will generate two beams of reflected light on the two liquid surfaces, and generate two different optical path offsets. Since the optical path offset is proportional to the actual reflection distance of the optical path, when both offset values ​​are transmitted to the photoelectric detection device, the optical path offset can be quickly obtained. The exact distance of the reflection point corresponds to the actual height of the oil layer. After the obtained value is fed back to the equipment system, the mechanical transmission component can be flexibly controlled under the support of data to intermittently lower the liquid inlet end of the oil suction pipe to the specified height range to ensure that the extracted oil is rarely mixed with external liquid. The mechanism accurately obtains the oil layer height through laser measurement, and with the cooperation of the mechanical transmission component, fully transfers the upper layer of oil. The process is intermittent extraction and the oil will not shake, thereby preventing the oil from diffusing into the alkali solution again, greatly reducing the amount of internal and external liquid mixed with the oil, reducing the difficulty of subsequent distillation, and shortening the time of the steps.

[0018] 2. The present invention is provided with a drying and turning mechanism. During the algae powder preparation stage, the clumping algae cells can be placed on the hollow mesh plate at a fixed point. The mechanical transmission component contained in the mechanism can drive the booster bar to continuously push the clumping algae cells, and gradually fill the blank area on the hollow mesh plate with them. Because the booster bar is flush with the top of the first rectangular frame, it will have the effect of scraping and smoothing the clumping algae cells, and reasonably control the transfer amount of the clumping algae cells, so that the clumping algae cells can be evenly spread on the hollow mesh plate. Furthermore, the high temperature generated by the high-resistance electric heating tube can fully cover the bottom of the hollow mesh plate. Combined with the former, it can ensure that the drying rate of the clumping algae cells on the hollow mesh plate is consistent, thereby improving the subsequent algae powder generation quality.

When the clustered algae cells continue to fall onto the hollow mesh plate 405, the slowly rotating booster bar 412 can continuously push part of the clustered algae cells to fill the blank area on the hollow mesh plate 405, and under the high pressure of the booster bar 412, the clustered algae cells will not overflow, and the evenly spread clustered algae cells make the algae powder output consistent at each location.

[0029] according to Figure 8 and Fig. 9 As shown, two load-bearing frames 413 are welded to the front surface of the first rectangular frame 403, a second rectangular frame 414 is fixedly installed between the outer walls of the two load-bearing frames 413, a group of lining plates 415 are fixedly installed between the two sides of the inner wall of the second rectangular frame 414, and a group of lining plates 415 are provided with high-resistance electric heating pipes 416 inside.

[0030] according to Figure 7 and Figure 8 As shown, the front and rear surfaces of the first rectangular frame 403 are respectively fixedly installed with the first external plate 417 and the second external plate 418, the shaft ends of the forward and reverse servo motors 402 are fixedly inserted inside the first external plate 417, the outer wall of the second external plate 418 is fixedly installed with a locking sleeve 419, the interior of the locking sleeve 419 is fixedly inserted with a first solid rod 420, the inner wall of the drying bin 2 is fixedly installed with a connecting sleeve 421, one end of the outer wall of the first solid rod 420 is movably inserted inside the connecting sleeve 421, a material gathering funnel 422 is fixedly installed at the bottom of the drying bin 2, and the bottom of the material gathering funnel 422 is fixedly connected to a second square tube 423, by presetting the above-mentioned components and utilizing the mutual coordination of the components, the first rectangular frame 403 and its connected components can be flexibly rotated inside the drying bin 2 to realize the free pouring of the algae powder.

[0031] according to Figure 3 , Fig.11 and Fig.13As shown, the shaft end of the first electric push rod 506 is fixedly sleeved with a roller bearing, and the outer shaft outer wall of the roller bearing is fixedly sleeved with a second flange 509, the bottom of the second flange 509 is fixedly installed with a second solid rod 510, the bottom of the lower support plate 502 is fixedly installed with an organic variable component 525, a transmission rod 527 is movably inserted at the center of the separation barrel 503, the output end of the organic variable component 525 is connected to the bottom of the transmission rod 527, an adapter slide 526 is provided at the bottom of the second solid rod 510, a docking joint 528 is fixedly installed on the top of the transmission rod 527, and a group of stirring components 529 are fixedly installed on the outer wall of the second solid rod 510.

[0032] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig.11 As shown, the top of the bottom bracket 501 is connected to the bottom of the drying bin 2, a cover 6 is provided on the top of the mixing bin 1, the top of the cover 6 is fixedly connected to a third-party rectangular tube 7, a second electric valve 8 is provided inside the third-party rectangular tube 7, and grafting plates 9 are fixedly installed on the four outer walls of the lower support plate 502, and adjustable feet 10 are fixedly installed on the outer wall of each grafting plate 9. By presetting the above components, the adjustable feet 10 can be freely adjusted according to the ground conditions of the area to avoid tilting of the equipment body, affecting the normal operation of each mechanism, and reducing the limitations of equipment use.

[0033] The effect achieved by the entire mechanism is as follows: during the equipment preparation stage, the equipment is first moved to the designated work area, the height of each adjustable foot 10 is reasonably adjusted according to the ground conditions, the equipment body is straightened, and then the external lines are respectively inserted into the equipment's main power supply and the independent power supply 305 to provide energy for the multiple electrical components contained therein.

[0034] In the fermentation liquid agglomeration stage, the second electric valve 8 is opened to open the channel in the third rectangular tube 7, and a proper amount of Schizochytrium fermentation liquid is injected into the mixing chamber 1 through the third rectangular tube 7, and then a proper amount of flocculant is injected into the mixing chamber 1 through the channel. After completion, the two can fully wrap the vibration rod 303, and the independent power supply 305 is turned on. Energy is transmitted by the first wire 306 and the second wire 307, and each vibration rod 303 is powered. The vibration generated on its surface can accelerate the mixing of Schizochytrium fermentation liquid and flocculant, and promote the formation of agglomerated algal cells.

[0035] In the algae powder preparation stage, the first electric valve 309 is turned on to open the internal channel of the first square tube 308. By utilizing the certain fluidity of the clumping algae cells, the clumping algae cells in the mixing chamber 1 will continue to be transported by the first square tube 308 and the extended curved tube 310, and transferred from one side of the first rectangular frame 403 to the top of the hollow mesh plate 405. At the same time, the driving motor 408 is turned on to drive the booster bar 412 on the horizontal rod 411 to rotate slowly, and the accumulated part of the clumping algae cells are continuously pushed into the blank area on the hollow mesh plate 405 until the top of the hollow mesh plate 405 is completely filled, and the booster bar 412 is used to scrape them downward, so that the clumping algae cells are finally evenly spread on the hollow mesh plate 405, and the first electric valve 309 is closed in time. The internal channel of the first square tube 308 stops the transfer of the clumping algae cells, and further energizes the high-resistance electric heating tube 416, which can continuously diffuse high temperature to the bottom of the hollow mesh plate 405. On the one hand, it heats the hollow mesh plate 405 body, and on the other hand, the divergence of each notch of the hollow mesh plate 405 can directly act on the evenly spread clumping algae cells, gradually drying the moisture in the clumping algae cells, and promoting the generation of algae powder. After the drying time is reached, the forward and reverse servo motor 402 is turned on, and the movable connection between the first solid rod 420 and the connecting sleeve 421 is used to drive the first rectangular frame 403 and its connected parts to turn over, gradually pouring the algae powder on the hollow mesh plate 405 downward, and gathering it in the gathering funnel 422, and then discharged from the second square tube 423.

[0036] In the stirring and separation stage, before the algae powder is transferred, a proper amount of composite alkali solution is manually injected into the separation barrel 503, and the heating element at the bottom of the separation barrel 503 is energized to quickly heat the composite alkali solution to less than 80°C. When the algae powder is completely transferred to the first rectangular frame 403 through the second square tube 423, it can be quickly mixed with the high-temperature alkali solution, and the wall breaking reaction proceeds. The first electric push rod 506 is turned on, and its inner axis extends outward, driving the second flange 509 and its connected parts to slowly move downward, gradually allowing the docking joint 528 to be accurately inserted into the interior of the matching slide 526, completing the combination of the second solid rod 510 and the machine-changing component 525. The machine-changing component 525 is turned on and acts on the transmission rod 527. By utilizing the physical properties of the roller bearing, the stirring component 529 on the second solid rod 510 is driven to rotate at a uniform speed in the high-temperature alkali solution to accelerate the wall breaking reaction. The generated oil will continue to separate the oil body and the alkali solution under the centrifugal force of the rotating liquid flow. After the stirring time is reached, the first electric push rod 506 resets each component.

[0037] In the oil layer measurement stage, after the reaction solution has been left to stand for a period of time, the separated oil and alkali solution are layered, with the oil layer on top. The laser transmitter 513 is turned on to emit a laser beam vertically into the oil layer. Due to the difference in light transmittance and density between the oil body and the alkali solution, when the light beam contacts the two liquid surfaces, the capture window 515 receives the different light beams reflected by the two liquid surfaces respectively, and obtains two optical path offsets. The obtained data is transmitted to the photoelectric detection device 512 in real time via the information line 516. According to the characteristic that the optical path offset is proportional to the actual reflection distance of the optical path, the photoelectric detection device 512 calculates two The distance between the reflection points of the light beams can accurately obtain the actual height of the oil layer, and the measured data can be shared with the equipment system. When the outer tube is connected to the output end of the liquid pump 518, its end is inserted into the collection container, and the second electric push rod 520 is further turned on to drive the oil suction pipe 521 to slowly descend until it contacts the oil layer, and the liquid pump 518 is started to make the liquid inlet end of the oil suction pipe 521 have a certain adsorption force. The system intermittently controls the extension length of the inner shaft of the second electric push rod 520 according to the numerical limit. During the process, the oil body is gradually extracted until the liquid inlet end of the oil suction pipe 521 descends to the specified height range.
