Microalgae filtering barrel

Abstract

The invention discloses a microalgae filtering barrel. The microalgae filtering barrel comprises a water tank, wherein a water feeding tube is arranged on the bottom of the water tank; a pressure resisting tube is longitudinally arranged in the water tank in a penetrating manner; a tray sleeves a portion, which is close to the bottom of the water tank, of the pressure resisting tube; a top cover is arranged on a portion, which is close to the upper edge of the water tank, of the pressure resisting tube; a funnel-shaped filtering screen with the large top and the small bottom is arranged between the edge of the top cover and the edge of the tray; a water overflowing tube is arranged on a portion, which is close to the upper edge, of a side surface of the water tank; one end of the pressure resisting tube is connected with an ozone inflating device; a pressure resisting valve is arranged at the other end of the pressure resisting tube; and a through hole is formed in a portion, which is positioned between the top cover and the tray, of the pressure resisting tube. The microalgae filtering barrel has the advantages that microalgae can be concentrated conveniently, water of algae liquid can be extracted, sundry algae can be prevented from being bred and accumulated, pollution on water is low, and the microalgae filtering barrel is easy and convenient to operate, not easy to block, high in reliability and low in cost.

Description

technical field [0001] The invention relates to equipment for preparing and extracting open bait for aquaculture, in particular to a microalgae filter bucket. Background technique [0002] In order to ensure the survival rate of fry, it is often necessary to supply palatable, rich and nutritious open bait in the early stage of breeding. At present, several open baits commonly used in the seedling cultivation process are egg yolk, soybean milk, rotifers, algae and aquatic microecological preparations. Algae individuals are smaller than rotifers, and are suitable for use as opening bait in the early opening stage of fish fry. As the fry grow, the mouth cracks widen, and rotifers become the most suitable bait. The two are complementary. The prior art, such as authorized announcement number CN 203613063 U, discloses a multi-phase whole-process comprehensive water processor. The utility model relates to a comprehensive water processor, in particular to a multi-phase whole-proc...
