[0002] In aquaculture, algae serve as an important source of feed and a water quality regulator. The cultivation and concentration processes of algae directly affect aquaculture efficiency and costs. Algae concentration devices typically reduce the water content in algal solutions and increase algae concentration through solid-liquid separation and circulating filtration, facilitating storage, transportation, and subsequent feeding. Therefore, they occupy a key position in the aquaculture industry chain. With the promotion of intensive aquaculture models, the demand for efficient and automated algae concentration equipment is increasing, leading to the development of various concentration devices aimed at improving the economy and practicality of algae treatment by optimizing separation efficiency and reducing energy consumption.

A water pipe 62 is fixedly connected to the rear surface of the water tank 61 for replenishing water to the water tank 61. The end of the water pipe 62 away from the water tank 61 is connected to an external water source. A baffle 65 is elastically connected to the inner wall of the water tank 61 by a compression spring 64. The baffle 65 is used to prevent water in the water tank 61 from entering the flushing pipe 66. A flushing pipe 66 is fixedly connected to the front surface of the water tank 61. A sprayer 67 is provided at the front end of the flushing pipe 66 for flushing the filter plate 51. The sprayer 67 is prior art and can be implemented by those skilled in the art. Since this is existing technology, it will not be described in detail in this case.

The guide block 75 is slidably connected to the inner wall of the guide groove 77. A second guide rod 76 is rotatably connected to the upper surface of the support plate 71. A motor 78 is fixedly installed on the lower surface of the support block 72. The motor 78 is connected to the guide rod... The guide rod 74 is connected to the lower surface of the first guide rod 74. The rear end of the guide rod 74 is fixedly connected to the connecting rod 79. The lower surface of the connecting rod 79 is fixedly connected to the swing plate 710, which is used to swing left and right to stir the algae liquid. The output shaft of the motor 78 is fixedly connected to the front end of the lower surface of the second guide rod 76, which is used to rotate the second guide rod 76 to drive the guide block 75 to slide in the guide groove 77 of the first guide rod 74. The output shaft of the motor 78 passes through the inner surface of the support block 72 to avoid motion interference caused by the output shaft of the motor 78. The end of the second guide rod 76 away from the motor 78 is hinged to the lower surface of the guide block 75. The moving guide rod 76 will drive the guide block 75 to press against the inner wall of the guide groove 77, causing the first guide rod 74 to swing.

[0038] Working principle: The algal liquid to be treated first enters the sedimentation tank 4. The lower half of the sedimentation tank 4 is a conical structure that is wider at the top and narrower at the bottom, which can guide the algal liquid to gather at the bottom. After sedimentation, the algal liquid is discharged through the discharge pipe 52 at the bottom of the sedimentation tank 4 and flows onto the filter plate 51.

[0039] The filter plate 51 is an inclined surface that gradually slopes upward from front to back. The water in the algal solution permeates through the filter holes of the filter plate 51 to the collection tank 2 below, while the algae are trapped and slide along the inclined surface to the front end of the collection tank 2, completing the initial solid-liquid separation and algae collection. The algal solution will fall into the receiving tank 3 through the filter holes. The inner wall of the bottom end of the receiving tank 3 is also inclined to facilitate liquid collection. The circulation pipe 54 on the left side of the receiving tank 3 works with the water pump 53 to pump the algal solution back into the sedimentation tank 4, forming a circulation path of sedimentation tank 4, filter plate 51, receiving tank 3, and sedimentation tank 4.

[0040] Through circulation, algae can be collected in collection tank 2.

[0041] After the motor 78 starts, its output shaft drives the second guide rod 76 to rotate. The end of the second guide rod 76 away from the motor 78 is hinged to the guide block 75. The guide block 75 slides in the guide groove 77 of the first guide rod 74, thereby pushing the first guide rod 74 to swing left and right with the positioning block 73 as the fulcrum. The connecting rod 79 at the lower end of the first guide rod 74 drives the swing plate 710 to swing left and right synchronously, stirring the algae liquid in the receiving tank 3, so that the algae are evenly dispersed in the liquid, ensuring that they can re-enter the sedimentation tank 4 with the algae liquid during circulation, avoiding resource waste, and ensuring that the algae liquid is evenly distributed, which is convenient for algae cultivation.

[0042] To prevent the filter plate 51 from being clogged by trapped algae, the flushing assembly 6 can achieve automatic cleaning. The water tank 61 is connected to an external water source to store clean water through the water pipe 62. The baffle 65 inside the water tank 61 is connected to the inner wall through the compression spring 64. Under normal conditions, the baffle 65 closes the flushing pipe 66 under the action of the spring force. When the liquid level in the sedimentation tank 4 drops, the baffle 65 is pulled upward by the pull rope 63 to overcome the spring force and open the flushing pipe 66. The clean water in the water tank 61 is transported to the sprayer 67 through the flushing pipe 66. The sprayer 67 sprays water onto the upper surface of the filter plate 51 through multiple spray holes to flush away the trapped algae and prevent the filter holes from clogging. When the liquid level in the sedimentation tank 4 rises, the hollow annular float ring 68 does not hinder the liquid flow and floats upward. The baffle 65 is reset under the action of the compression spring 64, closing the flushing pipe 66 and stopping the flushing, thus saving water resources.
