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:

[0005] 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.

[0006] Therefore, we propose a microalgae oil separation and purification device to solve the above-mentioned problems. Summary of the invention

[0007] 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.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 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.

[0022] 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.

[0040] According to Figure 1 、 Figure 5 and Figure 6 As shown, the mixing and flocculation mechanism 3 includes a group of hollow covers 301.

By utilizing the physical vibration generated on the surface of the vibrating rods 303, the mixing of the two can be accelerated, and the algal cells can be accelerated to aggregate into large lumps.

[0041] According to Figure 5 and Figure 6 As shown, a wiring base 304 and an independent power supply 305 are fixedly installed on the rear surface of the mixing bin 1 respectively. The output end of the independent power supply 305 is fixedly connected to a first wire 306. The output end of the first wire 306 is connected to the wiring end of the wiring base 304. A group of second wires 307 are fixedly connected inside the wiring base 304, and the number of the group of second wires 307 is equal to that of a group of power supply connectors 302.

By presetting the above components, the set independent power supply 305 can independently supply power to the vibrating rod 303 to ensure the stability of energy transmission and ensure the continuous oscillation mixing.

[0042] According to Figure 5 and Figure 6 As shown, a first square tube 308 is fixedly communicated with the bottom of the mixing bin 1. The discharging end of the first square tube 308 is fixedly communicated with an extension elbow 310. A first electric valve 309 is arranged inside the first square tube 308. By presetting the above components, by using the certain fluidity of the volvox cells, the volvox cells can be transferred to the hollow mesh plate 405 through the transportation of the first square tube 308 and the extension elbow 310.

[0043] According to Figure 1 、 Figure 7 、 Figure 8 and Figure 9 As shown, the drying and turning mechanism 4 includes a first locking frame 401. The first locking frame 401 is fixedly installed on the rear surface of the drying bin 2. A forward and reverse servo motor 402 is fixedly installed inside the first locking frame 401. A first rectangular frame 403 is movably arranged inside the drying bin 2. A positioning frame 404 is fixedly installed on the inner wall of the first rectangular frame 403. A hollow mesh plate 405 is fixedly embedded inside the positioning frame 404. By presetting the above components, there are a plurality of equally spaced small notches in the hollow mesh plate 405. Furthermore, the high temperature diffused at the bottom thereof will diverge into the volvox cells from each notch, accelerating the water loss rate and shortening the algal powder generation time.

[0044] According to Figure 8 、 Figure 9 and Figure 10As shown, a first support 406 is fixedly installed at the top of the first rectangular frame 403. A heat insulation sleeve 407 is fixedly installed at the center of the first support 406. A drive motor 408 is fixedly inserted inside the heat insulation sleeve 407.

By presetting the above components, the booster bar 412 is flush with the top of the first rectangular frame 403. After the colonial algae cells continuously fall onto the hollow mesh plate 405, the slowly rotating booster bar 412 can continuously push some of the colonial algae cells to fill the blank areas on the hollow mesh plate 405. And under the pressing of the height of the booster bar 412, the colonial algae cells will not overflow. The evenly spread colonial algae cells make the algal powder output consistent at each place.

[0045] According to Figure 8 and Figure 9 As shown, two load-bearing frames 413 are welded on the front surface of the first rectangular frame 403. A second rectangular frame 414 is fixedly installed between the outer surfaces of the two load-bearing frames 413. A group of inner lining plates 415 are fixedly installed between the two inner walls of the second rectangular frame 414. A high-resistance electric heating tube 416 is arranged inside the group of inner lining plates 415. By presetting the above components, after the high-resistance electric heating tube 416 is powered on, it can continuously dissipate heat to the bottom of the hollow mesh plate 405, providing necessary conditions for drying the colonial algae cells.

[0046] According to Figure 7 and Figure 8 As shown, a first outer plate 417 and a second outer plate 418 are respectively fixedly installed on the front and back surfaces of the first rectangular frame 403. The shaft end of the forward and reverse servo motor 402 is fixedly inserted inside the first outer plate 417. A locking sleeve 419 is fixedly installed on the outer surface of the second outer plate 418. A first solid rod 420 is fixedly inserted inside the locking sleeve 419.

A material collecting funnel 422 is fixedly installed at the bottom of the drying bin 2. The bottom of the material collecting funnel 422 is fixedly communicated with a second square tube 423. By presetting the above components, through the mutual cooperation of each component, the first rectangular frame 403 and its connected components can rotate flexibly inside the drying bin 2 to realize the free pouring of the algal powder.

[0047] According to Figure 3 、 Figure 11 and Figure 13As shown, a roller bearing is fixedly sleeved on the shaft end of the first electric push rod 506, and a second flange 509 is fixedly sleeved on the outer wall of the outer shaft of the roller bearing. A second solid rod 510 is fixedly installed at the bottom of the second flange 509. A machine variable component 525 is fixedly installed at the bottom of the lower support plate 502. A transmission rod 527 is movably inserted at the center of the separation barrel 503. The output end of the machine variable component 525 is connected to the bottom of the transmission rod 527. An adaptation slideway 526 is opened at the bottom of the second solid rod 510. A docking head 528 is fixedly installed at the top of the transmission rod 527. A set of stirring components 529 is fixedly installed on the outer wall of the second solid rod 510.

[0048] According to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 11 shown, the top of the bottom bracket 501 is connected to the bottom of the drying bin 2. A cover 6 is provided at the top of the mixing bin 1. A third square pipe 7 is fixedly communicated at the top of the cover 6. A second electric valve 8 is provided inside the third square pipe 7. Grafting plates 9 are fixedly installed on the four outer walls of the lower support plate 502. Adjustable support feet 10 are fixedly installed on the outer wall of each grafting plate 9. By presetting the above components, the adjustable support feet 10 can be freely adjusted according to the ground conditions of the area, avoiding the inclination of the equipment body and affecting the normal operation of each mechanism, and reducing the use limitations of the equipment.

[0049] The effect achieved by the entire mechanism is as follows: In the equipment preparation stage, first move the equipment to the designated working area, reasonably adjust the height of each adjustable support foot 10 according to the ground conditions, straighten the equipment body, and then insert the external wires into the main power supply and the independent power supply 305 of the equipment respectively to provide energy for multiple electrical components included therein.

[0050] In the stage of the fermentation broth forming into a mass, open the second electric valve 8, open the inner channel of the third square pipe 7, and inject an appropriate amount of Schizochytrium fermentation broth into the mixing bin 1 through the transportation of the third square pipe 7, and then inject an appropriate amount of flocculant into the mixing bin 1 through the channel. After completion, both can fully wrap the vibrating rod 303. Open the independent power supply 305, and the energy is transmitted by the first wire 306 and the second wire 307, and power is supplied to each vibrating rod 303. The vibration generated on its surface can accelerate the mixing of the Schizochytrium fermentation broth and the flocculant, and promote the formation of agglomerated algal cells.

[0051] During the algal powder preparation stage, the first electric valve 309 is opened to open the internal passage of the first square tube 308. By taking advantage of the certain fluidity of the agglomerated algal cells, the agglomerated algal cells in the mixing bin 1 will continuously be transported through the first square tube 308 and the extended elbow 310, and transferred from one side of the first rectangular frame 403 to above the hollow mesh plate 405. At the same time, the drive motor 408 is started to drive the boosting strip 412 on the horizontal rod 411 to slowly rotate, continuously pushing some of the accumulated agglomerated algal cells into the blank area on the hollow mesh plate 405 until the area above the hollow mesh plate 405 is completely filled. Then, by means of the pressing and scraping of the boosting strip 412, the agglomerated algal cells are finally evenly spread on the hollow mesh plate 405. The first electric valve 309 timely closes the internal passage of the first square tube 308 to stop the transfer of the agglomerated algal cells. Further, the high-resistance electric heating tube 416 is powered on, and high temperature can be continuously diffused below the hollow mesh plate 405. On the one hand, it heats the hollow mesh plate 405 itself, and on the other hand, it can directly act on the evenly spread agglomerated algal cells through the divergence of each notch of the hollow mesh plate 405, gradually drying the water in the agglomerated algal cells and promoting the generation of algal powder. After the drying time is reached, the positive and negative servo motor 402 is started. By using the movable connection of the first solid rod 420 and the connecting sleeve 421, the first rectangular frame 403 and its connected components are driven to turn over, and the algal powder on the hollow mesh plate 405 is gradually poured down and gathered in the material collecting funnel 422, and then discharged through the second square tube 423.

[0052] During the stirring and separation stage, before the transfer of the algal powder, an appropriate 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 powered on to quickly heat the composite alkali solution to within 80 °C. When the algal 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 will follow. The first electric push rod 506 is started, and its inner shaft extends outwards, driving the second flange 509 and its connected components to slowly move downwards, gradually making the docking head 528 accurately inserted into the internal of the adapter slideway 526 to complete the combination of the second solid rod 510 and the mechanical transformation component 525. The mechanical transformation component 525 is started and acts on the transmission rod 527. By using the physical characteristics of the roller bearing, the stirring component 529 on the second solid rod 510 is driven to rotate uniformly in the high-temperature alkali solution, accelerating the progress of the wall-breaking reaction. The generated oil will be continuously separated from the alkali solution under the centrifugation of the rotating liquid flow. After the stirring duration is reached, each component is reset by the first electric push rod 506.

[0053] In the oil layer measurement stage, after the reaction liquid has been static for a period of time, the separated grease and lye are stratified, with the oil layer on top. The laser emission head 513 is turned on, and a laser beam is vertically emitted into the oil layer. Due to the different light transmittance and density of the oil body and the lye, when the beam contacts the two liquid surfaces, the capture window 515 receives the different beams reflected by the two liquid surfaces respectively, and two optical path offsets are obtained. The data obtained is transmitted in real time to the photoelectric detection device 512 through 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 the distance between the reflection points of the two beams, accurately obtains 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 extraction pump 518, its end is inserted into the collection container. Further, the second electric push rod 520 is turned on to drive the oil suction pipe 521 to slowly descend until it contacts the oil layer. The liquid extraction 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, and gradually extracts the oil body during the process until the liquid inlet end of the oil suction pipe 521 descends to the specified height range.
