Technical Field

[0001] The utility model relates to the technical field of aquaculture, and in particular to an aquaculture circulating water system. Background Art

[0002] Green shrimp mostly live in shallow rivers along the coast of lakes and in waters with abundant aquatic plants. The depth of their habitat varies with the seasons. Green shrimp is one of the freshwater shrimps with higher economic value. It has the characteristics of fast growth, large size and rapid reproduction. Artificial breeding of green shrimp also has good prospects, but the water quality in which green shrimp live must be weakly alkaline or neutral, oxygen-rich, etc., which makes the water quality for green shrimp breeding particularly important.

Then the motor 4 is started to make the driving plate 14 drive the scraper block 18 at the lower end to reciprocate on the surface of the filter screen 7, and at the same time, the stirring blade 11 above is rotated to improve the oxygen absorption efficiency. The driving plate 14 drives the scraper block 18 to slide under the drive of the double-headed reciprocating screw rod 8, and the spring 17 above the scraper block 18 squeezes the scraper block 18 below so that its bottom end always presses against the upper outer wall of the filter screen 7. Then, the driving plate 14 drives the scraper block 18 to slide along the inclination angle of the filter screen 7 during the movement, so that it scrapes off the impurities above the filter screen 7 and pushes them into the storage grooves 21 on both sides below. After that, the impurities can be cleaned up by taking out the storage grooves 21, which reduces the difficulty of cleaning the filter screen 7 and avoids the blockage of the filter screen 7 caused by long-term filtration, which affects the effect of water circulation.
