This invention relates to the field of
shrimp aeration and
oxygenation technology, and discloses a self-sinking rubber tube for
aeration and
oxygenation in small-scale
shrimp farming. The tube includes an air distribution
pipe, an
oxygenation pump, and a liquid delivery pump. The air distribution
pipe has evenly distributed air holes, and one end of the air distribution
pipe has an air guide pipe. It also includes an
aeration pipe located outside the air distribution pipe, with a
spiral blade fixedly installed inside. The
spiral blade is fitted to the outer wall of the air distribution pipe. The aeration pipe has aeration holes arranged in a nine-hole spiral pattern, with the upper and lower
layers of holes staggered by approximately 1 cm. The holes are arranged in three rows at a central angle of 60°. The aeration pipe has two
layers: the inner layer is made of PVC material, which has good elasticity and shrinkage, while the outer layer is made of PP material, which has a
smooth surface, making it difficult for
algae and
dirt to adhere, reducing the risk of blockage. Furthermore, its
specific gravity is greater than water, allowing it to sink in water without the need for additional weights, making the arrangement convenient for management.
