The utility model discloses an aquatic firefly
larva breeding box with a
backwashing function, which comprises a box body, a partition plate is arranged in the box body, a water inlet
pipe is arranged at the top of the outer side surface of the box body, a floating
ball valve is connected onto the water inlet
pipe, a supporting layer is arranged below the partition plate, a filtering layer is arranged above the supporting layer, and a water outlet
pipe is arranged below the filtering layer. A connecting
water pipe is arranged on the box body, a water pump is installed on the outer side face of the box body, a water outlet pipe is arranged between the bearing layer and the partition plate, and a blow-off pipe is arranged at the top of the partition plate. According to the aquatic firefly
larva breeding box with the
backwashing function, through the arrangement of the water pump, the connecting
water pipe, the filtering layer and the water outlet pipe, water in breeding is continuously filtered, through the arrangement of the blow-off pipe, after the filtering effect of the filtering layer is reduced, the filtering material is subjected to
backwashing, impurities in the filtering material are discharged, and therefore the breeding effect of the aquatic firefly
larva is improved. Through the arrangement of the water inlet pipe and the floating
ball valve, water is supplemented to the culture box, and a good
culture environment for the aquatic fireflies is kept.
