Sieve bend filtering device for aquaculture

Abstract

The invention relates to a sieve bend filtering device for aquaculture, which comprises a water tank, a sieve bend and an automatic cleaning device, wherein a clear water trough is formed at the bottom of the water tank, a water outlet pipe is arranged on one side of the clear water trough, an overflow trough is arranged at the upper end part on the front side of the water tank, and a water inlet pipe is arranged on the outer side wall of the overflow trough; the upper end of a net body of the sieve bend is connected to the upper edge on the inner side of the overflow trough, the lower end is connected to the upper edge on the inner side of a pollution collecting trough fixed at the bottom of the water tank, and a pollution discharge port is arranged at the bottom of the pollution collecting trough; and the automatic cleaning device comprises a cleaning brush and a driving device, the bottom surface of the cleaning brush and the inner surfaces of the sieve bend and the pollution collecting trough are in consistent shapes, the driving device comprises a motor, a reduction gearbox and a transmission mechanism, the transmission mechanism comprises a threaded lead screw and a movable nut, and travel switches are further respectively arranged at two ends of the threaded lead screw. The favorable point is that a programmable timer is further arranged in the driving device, so that dirt retention on the net surface of the sieve bend can be removed by driving the cleaning brush to reciprocate along the horizontal direction which is parallel to the sieve bend in a timing manner; and the sieve bend filtering device for the aquaculture is simple in structure, reliable for operation and obvious in energy-saving effect.

Description

technical field [0001] The invention relates to the water body filtering technology in the field of aquaculture, in particular to a curved sieve filtering device for aquaculture with an automatic cleaning device. 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, t...

Problems solved by technology

Its disadvantage is that it has not effectively solved the problem of automatic cleaning of the curved screen surface. When the breeding load is high, it is even necessary to manually brush the screen surface once an hour to maintain the normal operation of the filter device.
