Abstract

The invention relates to filtering equipment for purifying aquacultural water. The filtering equipment for purifying the aquacultural water comprises a pedestal, a frustum-shaped screen, a driving shaft, a driving device, a water inlet pipeline, a water outlet pipeline, a backflush device and a control device, wherein the pedestal has a disk shape; a water storage space is formed in the middle of the bottom part of the pedestal; a pipe orifice communicated with the water outlet pipeline is arranged on one side wall of the bottom part of the pedestal; a sewage draining groove is formed in the pedestal; a plurality of sewage draining holes are formed at the bottom of the sewage draining groove; the frustum-shaped screen is formed by arranging a stainless steel surface on a fixed frame; a fixed part which has a small diameter and is fixedly connected to the driving shaft is arranged at the top of the fixed frame; a fixed hoop with a big diameter is arranged at the bottom of the fixed frame; the bottom edge of the fixed hoop extends to above the sewage draining groove; a plurality of reinforcing ribs are connected between the fixed part and the fixed hoop; the water inlet pipeline guides water to the top of the screen, so that under the action of gravity, the water flows downwards from the top of the screen, is filtered by the screen and then flows to the water storage space; and according to a user programmable program, the control device automatically controls the backflush device to synchronize with the rotation of the screen to flush the screen, so low-energy-consumption and high-efficiency automatic washing is realized.

Description

technical field [0001] The invention relates to water body purification technology in the field of aquaculture, in particular to a filtering device for purifying aquaculture water body. Background technique [0002] Circulating water treatment technology is the core part of the aquaculture system, and the technological advancement of the former determines the advancement, stability and operating economy of the latter. The primary task of water treatment in all aquaculture systems is to remove suspended solids in the water. These suspended solids include inorganic and organic components, mainly produced by biological excretion, biogel, and uningested food residues. The size varies from a few centimeters to a few microns. The organic fraction, so-called volatile suspended solids (VSS), contributes to oxygen depletion and biocombustion problems. Inorganic components contribute to the formation of silt deposits. From the diameter of the particles, the aquaculture water solids...
