Description

Technical Field

[0001] The present invention belongs to the technical field of microalgae oil separation, and specifically relates to a device for extracting and separating Schizochytrium oil. Background Art

[0002] As a microalgae rich in docosahexaenoic acid (DHA), Schizochytrium has problems such as low cell wall breaking efficiency, high solvent residue, and large DHA loss in traditional methods. In the early stage, high-pressure homogenization or mechanical grinding required complex equipment, high energy consumption, and was prone to cause oil peroxidation. Moreover, the special structure of the Schizochytrium cell wall resulted in too low oil extraction rate by conventional methods. Therefore, an oil separation device is needed.

[0003] Patent No. CN220618846U discloses a device for separating and purifying microalgae oil, including a storage tank. A drain pipe and an oil outlet are arranged on the outer wall of the storage tank. A support frame is arranged at the top of the storage tank. A liquid scraping component for scraping the residual liquid on the inner wall of the storage tank for distillation is arranged inside the support frame. The liquid scraping component includes a translation frame arranged inside the support frame. An I-shaped block is arranged inside the translation frame. A connecting rod and a cover plate are arranged at the bottom of the I-shaped block. Scrapers are arranged around the outer wall of the cover plate. A filter screen is arranged at the bottom of the cover plate. A cavity is arranged inside the cover plate. A sponge block and a pressing plate are arranged inside the cavity. The utility model realizes scraping and cleaning of the residual liquid on the wall of the distillation chamber, reduces the oil-water residue, and can prevent the oil-water from splashing, and captures the splashed oil-water and injects it into the distillation tank, reducing waste.

[0004] However, when this device is used, it cannot filter and screen Schizochytrium, and cannot effectively improve the oil extraction rate.

[0036] Adopting the above solution: After the schizochytrium algal mud solution enters the inside of the centrifuge cylinder 8, the oil outlet 9 is started, so that the oil outlet 9 drives the whole centrifuge cylinder 8 to rotate, thereby centrifuging the schizochytrium algal mud solution inside the centrifuge cylinder 8, separating the oil contained in the schizochytrium algal mud solution, and then extracting the oil. After the separation is completed, the oil is discharged through the oil outlet 9.

[0037] As Figures 1 to 5 shown in the figure, the filtering mechanism 4 includes a limiting plate 401, a filter plate 402 and an extension plate 403.

A first connecting rod 407 is rotatably connected inside the housing 1. The top end of the first connecting rod 407 is fixed with a first servo motor 408. An eccentric wheel 409 is fixed outside the first connecting rod 407. The return spring 404 is used to squeeze the extension plate 403 and keep it in the centered position. There are two groups of extension rods 405, and the extension rods 405 are symmetrically distributed about the central axis of the filter plate 402. The first servo motor 408 is fixed at the top end of the housing 1, and there are three groups of eccentric wheels 409.

[0039] Adopt the above - mentioned scheme: Add the Schizochytrium algae mud solution into the device through the feed inlet 3, so that the Schizochytrium algae mud solution is located at the top of the limiting plate 401. Start the first servo - motor 408, so that the first servo - motor 408 drives the first connecting rod 407 and the eccentric wheel 409 to rotate. Then, the eccentric wheel 409 squeezes and disengages from the trigger plate 406, and then drives the whole filter plate 402 to move. When disengaging, it is reset by the return spring 404, so that the Schizochytrium algae mud solution located at the top of the filter plate 402 shakes under the reciprocating movement of the filter plate 402, and then filters the Schizochytrium algae mud solution at the top, making it fall onto a group of filter plates 402 below for filtration. There are three groups of filter plates 402 in total, and the aperture of the filter holes of each group of filter plates 402 decreases from top to bottom, so as to improve the filtration effect. And heating tubes are installed on the inner wall of the housing 1 in the filtration area of the three groups of filter plates 402, so that when filtering the Schizochytrium algae mud solution, it is heated synchronously, assisting in opening the cell wall of Schizochytrium, so as to improve the oil yield in the subsequent separation process.

[0040] As Figures 1 to 7 shown, the heating mechanism 5 includes a collection cylinder 501, a second connecting rod 502 and a limiting wheel 503. The collection cylinder 501 is fixed inside the housing 1. The second connecting rod 502 is rotatably connected inside the collection cylinder 501. The limiting wheel 503 is fixed to the outside of the second connecting rod 502. The first bevel gear 504 is fixed to the outside of the second connecting rod 502. The second bevel gear 505 is fixed to the bottom end of the first connecting rod 407. The heating ring 506 is fixed to the outside of the collection cylinder 501. A slope is provided at the top of the collection cylinder 501, and a discharge port is provided at the bottom end of the collection cylinder 501. The second connecting rod 502 is rotatably connected to the housing 1. A number of groups of blades are provided on the outer wall of the limiting wheel 503, and the blades are equidistantly distributed about the central axis of the limiting wheel 503. A number of groups of teeth are provided on the outer wall of the first bevel gear 504, and a number of groups of teeth are provided on the outer wall of the second bevel gear 505. The first bevel gear 504 and the second bevel gear 505 are meshed.

[0041] Adopt the above - mentioned scheme: After filtering the Schizochytrium algae mud solution, it falls into the top of the collection cylinder 501 for collection and then into the slot of the limiting wheel 503. Start the heating ring 506 on the outer wall of the collection cylinder 501. The heating ring 506 heats, and the temperature of the heating ring 506 is higher than that of the heating tubes in the area of the upper filter plate 402, so that the Schizochytrium algae mud solution further breaks the cell wall due to the temperature difference, thus improving the oil yield. And while the first servo - motor 408 drives the first connecting rod 407 to rotate, it also drives the second bevel gear 505 to rotate. Through the second bevel gear 505, it drives the first bevel gear 504, the second connecting rod 502 and the limiting wheel 503 to rotate, so that the Schizochytrium algae mud solution is temporarily stored in the slot of the limiting wheel 503, heated to open the cell wall and then continues to fall.

[0042] As shown Figures 1 to 10 in FIG. Figures 1 to 10 , the air blowing mechanism 6 includes an air pump 601, an air delivery pipe 602 and a connector 603. The air pump 601 is fixed outside the collection cylinder 501. The output end of the air pump 601 is communicated with the air delivery pipe 602. The connector 603 is movably connected inside the air delivery pipe 602. There are four groups of air pumps 601, and the air pumps 601 are symmetrically distributed about the central axis of the collection cylinder 501. The air delivery pipe 602 is fixedly connected inside the collection cylinder 501, and the air delivery pipe 602 and the connector 603 are rotatably connected.

[0043] As shown Figures 1 to 10 in FIG. Figures 1 to 10 , a transmission blade 604 is fixed outside the connector 603, and a blow pipe 605 is fixed at the bottom end of the connector 603. A limiting ring 606 is fixed outside the air pump 601. There are several groups of transmission blades 604, and the transmission blades 604 are equidistantly distributed about the central axis of the connector 603. The blow pipe 605 is provided with two air outlets.

[0044] With the above scheme: when the Schizochytrium algae mud solution falls inside the collection cylinder 501 and contacts the transmission blade 604, the connector 603 and the blow pipe 605 rotate, thereby changing the positions of the connector 603 and the blow pipe 605. Start multiple groups of air pumps 601, so that the air pumps 601 blow air into the blow pipe 605 through the air delivery pipe 602. When the centrifuge cylinder 8 is not started for centrifugation, the overall rotation of the blow pipe 605 can blow and clean the inner wall of the centrifuge cylinder 8, and the Schizochytrium algae mud solution can fall into the centrifuge cylinder 8 along the transmission blade 604, the connector 603 and the blow pipe 605 to guide it. When the centrifuge cylinder 8 is centrifuging, there is no Schizochytrium algae mud solution on the top of the transmission blade 604. At this time, the whole connector 603 is in a stationary state. Start the air pump 601 to blow air and cooperate with the rotation of the centrifuge cylinder 8, so that the air flow blows the residual solid particles on the inner wall of the centrifuge cylinder 8, reduces the adhesion resistance, and improves the separation efficiency.

[0045] Working principle and usage process of the present invention: Add the Schizochytrium algal mud solution into the device through the feed port 3, so that the Schizochytrium algal mud solution is located at the top of the limiting plate 401. Start the first servo motor 408, so that the first servo motor 408 drives the first connecting rod 407 and the eccentric wheel 409 to rotate. Then, the eccentric wheel 409 squeezes and disengages from the trigger plate 406, thereby driving the overall movement of the filter plate 402 and using the return spring 404 to reset when disengaging. Make the Schizochytrium algal mud solution located at the top of the filter plate 402 shake under the reciprocating movement of the filter plate 402, thereby filtering the Schizochytrium algal mud solution at the top and making it fall onto a set of filter plates 402 below for filtering. There are three groups of filter plates 402 in total, and the pore diameters of the filter holes of each group of filter plates 402 decrease from top to bottom, so as to improve the filtering effect. And heating tubes are installed on the inner wall of the housing 1 in the filtering area of the three groups of filter plates 402, so that it is heated synchronously when filtering the Schizochytrium algal mud solution, assisting in opening the cell wall of Schizochytrium and increasing the oil yield in the subsequent separation process. And after filtering the Schizochytrium algal mud solution, it falls onto the top of the collection cylinder 501 for collection and falls into the slot of the limiting wheel 503. Start the heating ring 506 on the outer wall of the collection cylinder 501, and the heating ring 506 heats up, and the temperature of the heating ring 506 is higher than that of the heating tubes in the area of the upper filter plate 402, so that the Schizochytrium algal mud solution further breaks the cell wall after being affected by the temperature difference, thereby increasing the oil yield. And while the first servo motor 408 drives the first connecting rod 407 to rotate, it also drives the second bevel gear 505 to rotate. Through the second bevel gear 505, it drives the first bevel gear 504, the second connecting rod 502 and the limiting wheel 503 to rotate, so that the Schizochytrium algal mud solution is temporarily stored in the slot of the limiting wheel 503, heated to open the cell wall and then continues to fall. And after the Schizochytrium algal mud solution falls into the collection cylinder 501, it contacts the transmission blade 604, so that the connector 603 and the air blowing pipe 605 rotate, thereby changing the positions of the connector 603 and the air blowing pipe 605. Start multiple air pumps 601, so that the air pumps 601 blow air into the air blowing pipe 605 through the air delivery pipe 602. When the centrifuge cylinder 8 is not started for centrifugation, the rotation of the entire air blowing pipe 605 can blow air to clean the inner wall of the centrifuge cylinder 8, and the Schizochytrium algal mud solution can fall into the centrifuge cylinder 8 along the transmission blade 604, the connector 603 and the air blowing pipe 605 to guide it. When the centrifuge cylinder 8 is centrifuging, there is no Schizochytrium algal mud solution on the top of the transmission blade 604. At this time, the entire connector 603 is in a stationary state. Start the air pump 601 to blow air and cooperate with the rotation of the centrifuge cylinder 8 to make the airflow blow the solid particles remaining on the inner wall of the centrifuge cylinder 8, reduce the adhesion resistance and improve the separation efficiency. After the Schizochytrium algal mud solution enters the centrifuge cylinder 8, start the oil outlet 9, so that the oil outlet 9 drives the entire centrifuge cylinder 8 to rotate, thereby centrifuging the Schizochytrium algal mud solution inside the centrifuge cylinder 8 and separating the oil contained in the Schizochytrium algal mud solution, and then extracting the oil.After the separation is completed, the grease is discharged through the oil outlet 9.,
