[0033] Reference Figure 2-Figure 3The outer wall of the rotating shaft 52 is fixedly connected with a plurality of wall-breaking knives 53, and the wall-breaking knives 53 are provided with a plurality of groups. Through the cooperation between the plurality of wall-breaking knives 53, the microalgae cells are broken by the high-speed rotation of the wall-breaking knives 53. The bottom end of the outer wall of the rotating shaft 52 is fixedly connected with a plurality of cleaning plates 55. When the cleaning plates 55 rotate, they will drive the microalgae cells adsorbed on the bottom end of the mixing barrel 4 to be scraped off, and through the through holes on the surface of the cleaning plates, they will be broken by the wall-breaking knives 53 again, so as to prevent some microalgae cells from being adsorbed on the barrel body, resulting in a poor breaking effect. The outer wall of the rotating shaft 52 is fixedly connected with There are two sets of upper and lower fixed blocks 56, the inner wall of the fixed block 56 is elastically connected to the sliding column 58 through a limit spring 57, one end of the limit spring 57 is fixedly connected to the inner wall of the fixed block 56, and the other end of the limit spring 57 is fixedly connected to the outer wall of the sliding column 58. The function of the limit spring 57 is to apply elastic support to the scraper 54 when it is squeezed to prevent damage to the scraper 54 when encountering harder impurities. The sliding column 58 is slidably connected to the inner wall of the fixed block 56, and the outer wall of the sliding column 58 is fixedly connected to the scraper 54. The outer wall of the mixing barrel 4 is provided with a discharging component 6.
[0034] Reference Figure 1 and Figure 4 The discharging component 6 includes a discharging port 61, which is fixedly connected to the outer wall of the mixing barrel 4, and a shielding plate 65 and a filter screen 66 are in contact with the outer wall of the discharging port 61. The shielding plate 65 closes the discharging port 61 to prevent some microalgae cells from overflowing from the discharging port 61 when the mixing barrel 4 is crushed by the crushing component 5, and two groups of filter screens 66 with different finenesses are used alternately, so that different batches of microalgae cells can be discharged and filtered, and a fixed frame 62 is fixedly connected to the top of the outer wall of the discharging port 61, and a rotating rod 64 is rotatably connected to the inner wall of the fixed frame 62, and a group of shielding plates 65 are fixedly connected to the outer wall of the rotating rod 64, and two groups of filter screens 66 are fixedly connected to the outer wall of the rotating rod 64. Through the rotation of the rotating rod 64, a The baffle plate 65 and the two groups of filter screens 66 are used alternately. The inner wall of the fixed frame 62 is elastically connected to the plug rod 63 through a reset spring 67. One end of the reset spring 67 is fixedly connected to the inner wall of the fixed frame 62, and the other end of the reset spring 67 is fixedly connected to the surface of the plug rod 63. The function of the reset spring 67 is that when the plug rod 63 is pulled outward, there is no need for manual reset. It can be automatically reset by the elastic action of the reset spring 67. The plug rod 63 passes through and is slidably connected to the inner wall of the fixed frame 62. Three groups of through holes are opened on the surface of the rotating rod 64. The bottom end of the outer wall of the plug rod 63 is plugged into the inner wall of the through hole. The two are plugged in, so that the rotating rod 64 drives the baffle plate 65 and the two groups of filter screens 66 to rotate and adjust multiple positions for fixing.
[0035] Working principle: When loading and unloading materials into the mixing barrel 4, the plug rod 63 can be pulled to disengage its bottom end from the plugging of the rotating rod 64, thereby rotating the rotating rod 64 to drive the shielding plate 65 at the material outlet 61 to rotate, so that the material outlet 61 can be opened. At this time, the microalgae cells that need to be broken can enter the inner wall of the mixing barrel 4 from the material outlet 61. At this time, the shielding plate 65 can be rotated again to choose to block the material outlet 61, and the plug rod 63 can be released. It will be elastically acted on by the reset spring 67 to restore it to its initial position, thereby closing the material outlet through the shielding plate 65. 61 is closed, at this time, the motor B51 can be started to let the output shaft drive the rotating shaft 52 to rotate, and at the same time, the multiple sets of wall-breaking knives 53, the fixed block 56 and the cleaning plate 55 on the outer wall can rotate. When the wall-breaking knife 53 rotates, the microalgae cells will be broken, and at the same time, the fixed block 56 will drive the sliding column 58 to rotate synchronously during the rotation, thereby driving the scraper 54 to clean the inner wall of the mixing barrel 4, so as to prevent the microalgae cells from being adsorbed on the inner wall of the mixing barrel 4, and at the same time, the cleaning plate 55 will also clean the bottom end of the inner wall of the mixing barrel 4 to prevent adsorption at the bottom end.
[0036] After the microalgae cells are crushed, the plug rod 63 can be pulled to disengage its bottom end from the plugging of the rotating rod 64, thereby rotating the rotating rod 64 to disengage the shielding plate 65 from blocking the discharge port 61, so that the two sets of filter screens 66 can block the discharge port 61, thereby adjusting according to the batch of microalgae cells. After the adjustment is completed, the plug rod 63 is released and it will be elastically acted upon by the reset spring 67 to restore it to its initial position to be plugged into the through hole of the current position of the rotating rod 64, thereby fixing the position of the rotating rod 64 and the filter screen 66. At this time, the motor A2 can be started to allow its output shaft to drive the rotating shaft 3 to rotate, thereby driving the mixing barrel 4 to rotate, so that the discharge port 61 is facing the external collection box, thereby filtering the microalgae cells after the internal wall breaking is completed through the filter screen 66.
