[0035] Compared with the prior art, the fatty acid extraction equipment with the impurity separation structure using the above technical solution has the following beneficial effects:

[0036] 1. After the impurities are separated, they are accumulated on the inner bottom surface of the separation shell. At this time, the motor is started, and the output shaft of the motor drives the rotating shaft to swing. The rotating shaft drives the scraper to swing through the telescopic mechanism. Due to the action of the telescopic mechanism, the bottom end of the scraper is close to the inner bottom surface of the separation shell, and the scraper swings back and forth along the arc, so that the bottom end of the scraper scrapes the impurities accumulated on the inner bottom surface of the separation shell to avoid the impurities from being concentrated together, so as to facilitate the downward flow of raw materials and improve the extraction efficiency of fatty acids;

[0037] 2. In use, when the rotating shaft swings counterclockwise, the rotating shaft drives the arc plate to swing counterclockwise through the two second support plates. At the same time, the rotating shaft drives the scraper to swing counterclockwise through the telescopic mechanism. The bottom end of the scraper pushes the impurities accumulated on the bottom surface of the separation shell to move to the right to avoid the impurities from piling up together; when the pull rope moves to the right end of the arc groove, the rotating shaft switches to clockwise swing, and the rotating shaft drives the arc plate to swing clockwise through the two second support plates. At the same time, the rotating shaft drives the scraper to swing clockwise through the telescopic mechanism. During this process, the bottom end of the scraper is always in close contact with the bottom surface of the separation shell, so that the impurities on the right side of the scraper slowly flow downward to avoid a large amount of impurities. Then the rotating shaft drives the scraper to continue to swing to the left. When the pull rope contacts the left end of the arc-shaped groove, the top end of the pull rope is bent by the annular shell and the pull rope is located between the inner wall of the annular shell and the outer wall of the arc plate. At this time, the bottom end of the pull rope pulls the scraper upward, so that the bottom end of the scraper is separated from the inner bottom surface of the separation shell, thereby facilitating the impurities accumulated on the left end of the inner bottom surface of the separation shell to flow downward to the position directly below the rotating shaft, wherein the telescopic mechanism is in a compressed state; conversely, when the rotating shaft changes direction and rotates counterclockwise, the top end of the pull rope will straighten at the left end of the arc-shaped groove, and the telescopic mechanism will return to its initial length at this time, so that the bottom end of the scraper will again be tightly attached to the left side of the inner bottom surface of the separation shell, so as to facilitate the scraper to scrape the accumulated impurities to the right, and effectively avoid the impurities from accumulating on the left side of the inner bottom surface of the separation shell;

[0038] 3. During use, when the telescopic mechanism is in a vertical downward state, under the elastic force of the rectangular coil spring, the bottom end of the scraper is close to the inner bottom surface of the separation shell; when the top end of the pull rope is bent by the annular shell, the scraper is pulled upward by the pull rope, so that the scraper drives the telescopic head and the sliding block to move toward the telescopic seat, so that the rectangular coil spring is compressed and shortened by the sliding block and stores elastic potential energy, wherein the bottom end of the scraper is separated from the inner bottom surface of the separation shell, so as to facilitate the impurities on the left side of the inner bottom surface of the separation shell to flow toward the bottom of the rotating shaft; when the top end of the pull rope is separated from the left end of the arc groove, under the action of the elastic potential energy of the rectangular coil spring, the sliding block and the telescopic head drive the scraper to move toward the inner bottom surface of the separation shell, so that the scraper can scrape the accumulated impurities to the right, avoid the accumulation of large amounts of impurities, and improve the extraction efficiency of fatty acids.

[0039] 4. After using this equipment for a long time, more impurities will accumulate on the inner bottom surface of the separation shell. The impurities push the scraper upward, making the pull rope loose. At this time, the detection value of the tension sensor is equal to zero, and the control module controls the alarm to send an alarm signal. After receiving the alarm signal, the staff will clean up the impurities inside the separation shell in time to facilitate the smooth use of this device in the future.

[0049] The present invention is further described below in conjunction with the accompanying drawings.

[0051] A rotating shaft 32, wherein the rotating shaft 32 is rotatably disposed between two side walls of the separation shell 2, wherein the inner bottom surface of the separation shell 2 is an arc-shaped surface, and the axis of the arc-shaped surface coincides with the axis of the rotating shaft 32;

[0052] A driving member 31, wherein the driving member 31 is mounted on the outer wall of the separation housing 2, and an output shaft of the driving member 31 is fixedly connected to a rotating shaft 32, wherein the driving member 31 is a motor;

[0053] A telescopic mechanism, the top of which is fixedly connected to the bottom of the rotating shaft 32;

[0054] The scraper 45 is fixed on the bottom end of the telescopic mechanism, and the telescopic mechanism is used to make the bottom end of the scraper 45 contact the inner bottom surface of the separation shell 2.

[0055] During use, the staff adds the raw materials required for fatty acid extraction into the separation shell 2 through the feed port 21. The raw materials flow into the centrifuge 1 below after impurity separation in the separation shell 2. The centrifuge 1 extracts and processes the filtered raw materials to obtain fatty acids. Among them, the centrifuge 1 is the content of the prior art and is not described in detail here. The impurity separation process is as follows: the impurities are separated and accumulated on the inner bottom surface of the separation shell 2. At this time, the motor is started, and the output shaft of the motor drives the rotating shaft 32 to swing. The rotating shaft 32 drives the scraper 45 to swing through the telescopic mechanism. Due to the action of the telescopic mechanism, the bottom end of the scraper 45 is close to the inner bottom surface of the separation shell 2, and the scraper 45 swings back and forth along the arc, so that the bottom end of the scraper 45 scrapes the impurities accumulated on the inner bottom surface of the separation shell 2 to avoid the impurities from being concentrated and piled up together, so as to facilitate the downward flow of the raw materials and improve the extraction efficiency of fatty acids.

[0056] like Figure 4-Figure 7 As shown, it also includes:

[0057] an annular shell 51, the annular shell 51 surrounds the outer side of the rotating shaft 32; a first support plate 52, the first support plate 52 is fixed between the outer wall of the annular shell 51 and the inner wall of the separation shell 2, wherein the number of the first support plates 52 is two, and the two first support plates 52 are respectively fixed on the inner front wall and the inner rear wall of the separation shell 2;

[0058] An arc plate 54, which surrounds the outer side of the rotating shaft 32 and is located inside the annular shell 51; a second support plate 53, which is fixed between the surface of the rotating shaft 32 and the inner wall of the arc plate 54, wherein there are two second support plates 53, which are respectively fixed on the two ends of the inner wall of the arc plate 54, and the second support plates 53 are arranged along the radial direction of the rotating shaft 32.

[0059] An arc groove 55, wherein the arc groove 55 is formed on the annular shell 51 along a circumferential direction;

[0060] A pull rope 56, the pull rope 56 is fixed between the bottom surface of the arc plate 54 and the top surface of the scraper 45, and the pull rope 56 passes through the arc groove 55;

[0061] The central angle of the arc plate 54 is 170 degrees. When the pull rope 56 is in a vertical downward state, the left end of the arc groove 55 is located on the left side of the left end of the arc plate 54 .

[0062] refer to Figure 4 , Figure 5As shown, in use, when the rotating shaft 32 swings counterclockwise, the rotating shaft 32 drives the arc plate 54 to swing counterclockwise through the two second support plates 53. At the same time, the rotating shaft 32 drives the scraper 45 to swing counterclockwise through the telescopic mechanism, and the bottom end of the scraper 45 pushes the impurities accumulated on the bottom surface of the separation shell 2 to move to the right to avoid the impurities from piling up; when the pull rope 56 moves to the right end of the arc groove 55, the rotating shaft 32 switches to swing clockwise, and the rotating shaft 32 drives the arc plate 54 to swing clockwise through the two second support plates 53. At the same time, the rotating shaft 32 drives the scraper 45 to swing clockwise through the telescopic mechanism. During this process, the bottom end of the scraper 45 is always in close contact with the inner bottom surface of the separation shell 2, so that the impurities on the right side of the scraper 45 slowly flow downward to avoid a large amount of impurities. Then the rotating shaft 32 drives the scraper 45 to continue to swing to the left When the pull rope 56 contacts the left end of the arc groove 55, the top end of the pull rope 56 is bent by the annular shell 51 and the pull rope 56 is located between the inner wall of the annular shell 51 and the outer wall of the arc plate 54. At this time, the bottom end of the pull rope 56 pulls the scraper 45 upward, so that the bottom end of the scraper 45 is separated from the inner bottom surface of the separation shell 2, thereby facilitating the impurities accumulated on the left end of the inner bottom surface of the separation shell 2 to flow downward to the position directly below the rotating shaft 32, wherein the telescopic mechanism is in a compressed state; conversely, when the rotating shaft 32 changes direction and rotates counterclockwise, the top end of the pull rope 56 will straighten at the left end of the arc groove 55, and the telescopic mechanism will return to its initial length, so that the bottom end of the scraper 45 will again be close to the left side of the inner bottom surface of the separation shell 2, so as to facilitate the scraper 45 to scrape the accumulated impurities to the right, effectively avoiding the accumulation of impurities on the left side of the inner bottom surface of the separation shell 2. When the rotating shaft 32 swings back and forth, the scraper 45 can be driven to swing back and forth, thereby preventing impurities from piling up.

[0063] like Figure 8 As shown, the telescopic mechanism comprises:

[0064] A telescopic seat 41, the top surface of which is fixed on the bottom surface of the rotating shaft 32, and the telescopic seat 41 is a long cylindrical structure;

[0065] The telescopic head 42 has a top end slidably disposed inside the telescopic seat 41, a bottom surface of the telescopic head 42 is fixedly connected to a top surface of the scraper 45, and the telescopic head 42 is a slender rod-shaped structure;

[0066] A sliding block 44, wherein the sliding block 44 is slidably disposed in the telescopic seat 41, and the bottom surface of the sliding block 44 is fixedly connected to the top surface of the telescopic head 42;

[0067] The elastic member 43 is fixed between the top surface of the sliding block 44 and the inner top surface of the telescopic seat 41 , and the elastic member 43 is a rectangular coil spring.

[0068] There are two telescopic mechanisms, and the two telescopic mechanisms are symmetrically distributed about the pull rope 56 to improve the stability of the scraper 45 during the swinging process.

[0069] During use, when the telescopic mechanism is in a vertical downward state, under the elastic force of the rectangular coil spring, the bottom end of the scraper 45 is close to the inner bottom surface of the separation shell 2; when the top end of the pull rope 56 is bent by the annular shell 51, the scraper 45 is pulled upward by the pull rope 56, so that the scraper 45 drives the telescopic head 42 and the sliding block 44 to move toward the telescopic seat 41, so that the rectangular coil spring is compressed and shortened by the sliding block 44 and stores elastic potential energy, wherein the bottom end of the scraper 45 is separated from the inner bottom surface of the separation shell 2, so as to facilitate the impurities on the left side of the inner bottom surface of the separation shell 2 to flow toward the bottom of the rotating shaft 32; when the top end of the pull rope 56 is separated from the left end of the arc groove 55, under the action of the elastic potential energy of the rectangular coil spring, the sliding block 44 and the telescopic head 42 drive the scraper 45 to move toward the inner bottom surface of the separation shell 2, so that the scraper 45 can scrape the accumulated impurities to the right, avoid the accumulation of a large amount of impurities, and improve the extraction efficiency of fatty acids.

[0071] Two connecting rods 61, the two connecting rods 61 are respectively fixed on the outer walls of the two telescopic seats 41;

[0072] The scraper frame 62 is fixed between the bottom ends of the two connecting rods 61 , and the scraper plate 45 is slidably disposed in the scraper frame 62 .

[0073] During use, the two connecting rods 61 are used to fix the position of the scraper frame 62. When the pull rope 56 pulls the scraper 45 toward the rotating shaft 32, the scraper 45 slides relatively in the scraper frame 62, so that the scraper frame 62 can scrape off impurities attached to the surface of the scraper 45, preventing impurities from adhering to the scraper 45 for a long time and preventing impurities from corroding the scraper 45, thereby protecting the scraper 45.

[0074] like Figure 2 , Fig. 9 As shown, it also includes: a tension sensor 7, which is arranged on the bottom end of the pull rope 56; a control module, which is electrically connected to the tension sensor 7; a judgment module and an alarm, which are both electrically connected to the control module; when the judgment module determines that the detection value of the tension sensor 7 is zero, the control module controls the alarm to send an alarm signal.

[0075] In use, when the bottom end of the scraper 45 contacts the inner bottom surface of the separation shell 2, under the action of the elastic member 43, the pull rope 56 is in a tightened state, and the detection value of the tension sensor 7 is greater than zero; when the top end of the pull rope 56 is bent and pulls the scraper 45 upward, the pull rope 56 is also in a tightened state, and the detection value of the tension sensor 7 is greater than zero. The alarm is not activated in these two working states. After using this device for a long time, there will be more impurities accumulated on the inner bottom surface of the separation shell 2. The impurities push the scraper 45 upward, making the pull rope 56 in a loose state. At this time, the detection value of the tension sensor 7 is equal to zero, and the control module controls the alarm to send an alarm signal. After receiving the alarm signal, the staff will clean up the impurities inside the separation shell 2 in time to facilitate the smooth use of this device in the future.
