[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: a microalgae harvesting device, including a support leg 1 and a tank body 2, the number of the support legs 1 is set to be multiple, and the multiple support legs 1 are fixedly installed on the circumferential surface of the tank body 2 in a ring with equal intervals, and the tank body 2 is firmly supported by arranging multiple support legs 1, and the stability of the tank body 2 is improved when the microalgae culture mixed liquid is stirred, thereby providing a stable state during operation, a feed pipe 3 is fixedly connected to the left side of the tank body 2, and the microalgae culture mixed liquid is added into the tank body 2 through the feed pipe 3, so that the microalgae culture mixed liquid is fully reacted in the tank body 2, which is convenient for harvesting the microalgae culture mixed liquid, and a separation mechanism is arranged inside the feed pipe 3, and the separation mechanism includes a filter box 4, and a filter structure is arranged inside the filter box 4, which is convenient for filtering the microalgae in the microalgae culture mixed liquid and impurities in the water, and improving the quality of microalgae harvesting, and the filter box 4 is fixedly installed on the inner wall of the feed pipe 3, and a stirring mechanism is arranged inside the tank body 2.

[0032] Reference Figure 3 - Figure 5 The separation mechanism also includes a mounting plate 5, which is slidably mounted on the inner wall of the filter box 4. The sliding direction of the mounting plate 5 is forward and backward sliding. The front side of the mounting plate 5 is fixedly connected with a handle 6 for facilitating the staff to pull the mounting plate 5, which is conducive to quickly pulling the mounting plate 5. The separation mechanism also includes a pull ring 7. The number of pull rings 7 is set to two groups, and the pull ring 7 is set to a semicircular ring for easy use. The side where the two groups of pull rings 7 are close to each other is fixedly connected with a limit block 8 for limiting the displacement of the mounting plate 5. The inner wall of the limit block 8 is elastically connected to the inner wall of the filter box 4 by a spring 9. The spring 9 applies an elastic force to the limit block 8 away from the center direction of the filter box 4. The left and right side surfaces of the mounting plate 5 are provided with limit grooves 10. The shape of the limit groove 10 matches the shape of the limit block 8. The limit block 8 is plugged into the inner wall of the limit groove 10. The cooperation makes it possible to control the movement of the mounting plate 5, and when the limit block 8 is inserted into the limit groove 10, the filter plate 12 is just located at the working position inside the filter box 4, thereby improving the accuracy of installing the filter plate 12 and improving the solid-liquid separation effect of the mixed liquid. The separation mechanism also includes a filter plate 12, by which the microalgae and impurities in the mixed liquid can be filtered out to improve the solid-liquid separation effect. A card slot 11 is provided on the top surface of the mounting plate 5, and the filter plate 12 is plugged into the inner wall of the card slot 11. The number of filter plates 12 is set to two groups, and the filter plates 12 can be taken out from the inside of the card slot 11. During operation, one group of filter plates 12 is located at the working position inside the filter box 4, and the other group of filter plates 12 is located outside the filter box 4. By setting a redundant number of filter plates 12 as a backup, the filter plates 12 can be replaced without stopping the machine.

[0033] Reference Figure 1 - Figure 2The stirring mechanism includes a stirring motor 13, which is fixedly mounted on the top of the tank body 2. The stirring motor 13 is used to provide power. The stirring motor 13 is set as a servo motor. The stirring motor 13 can accurately control the rotation angle of its output shaft, which is convenient for adjusting the stirring speed and frequency. It can be adjusted according to different production needs and has good adaptability. The bottom end of the output shaft of the stirring motor 13 is fixedly connected with a rotating shaft 14, and the stirring motor 13 drives the rotating shaft 14 to rotate. The stirring mechanism includes a stirring blade 15, and the rotating shaft 14 passes through and is rotatably mounted on the inner wall of the tank body 2. The stirring blade 15 is fixedly mounted on the bottom of the rotating shaft 14. The blades of the stirring blade 15 are arranged in an inclined shape. The rotation of the stirring blade 15 allows the mixed liquid inside the tank body 2 to convect up and down, preventing the microalgae in the mixed liquid from sinking to the bottom, and improving the stirring effect. The bottom of the tank body 2 is fixedly connected with a discharge pipe 16 for discharging the mixed liquid inside the tank body 2, and the front of the tank body 2 is fixedly connected with a controller 17 for controlling the working state of the stirring motor 13, which is convenient for controlling the start and stop of the stirring motor 13.

[0034] Working principle: When in use, the microalgae mixture is extracted from the culture pool and injected into the tank body 2 through the feed pipe 3. The microalgae mixture passing through the feed pipe 3 will be filtered by the filter plate 12 inside the filter box 4. When the filter plate 12 needs to be disassembled and replaced after long-term use, the pull rings 7 on both sides of the filter box 4 are pulled outward. The movement of the pull rings 7 drives the limit blocks 8 to move outward to overcome the elastic force of the springs 9 until the limit blocks 8 are completely separated from the inside of the limit grooves 10. At this time, the limit blocks 8 will no longer restrict the mounting plate 5. Then the handle 6 is pulled forward. The movement of the handle 6 drives the mounting plate 5 to move, so that the filter plate 12 inside the filter box 4 is pulled out of the outside of the filter box 4. Then the filter plate 12 can be easily taken out from the inside of the card slot 11, so as to replace the filter plate 12.

[0035] The filtered microalgae mixed liquid enters the interior of the tank body 2, and the power supply of the stirring motor 13 is started through the controller 17. The stirring motor 13 drives the rotating shaft 14 to rotate, and the rotation of the rotating shaft 14 drives the stirring blades 15 to rotate. The stirring blades 15 rotate so that the microalgae mixed liquid inside the tank body 2 is evenly mixed. The inclined stirring blades 15 allow the mixed liquid inside the tank body 2 to convect up and down, thereby preventing the microalgae from sinking to the bottom during the stirring process, further improving the stirring effect, and after the stirring is completed, it is discharged to the outside of the tank body 2 through the discharge pipe 16.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
