A self-cleaning fish tank

Abstract

The inventiondiscloses aself-washing fish tank which comprises a fish tank body, a clean water tank, a filtering tank, a high-level water tank, a nitratlon reaction tank and a siphon casing, wherein a fish tank water outlet tube is communicated between the fish tank body and thehigh-level water tank; a high-level water tank water outlet tube is communicated between the high-level water tank and the upper part of the filtering tank; the filtering tank is internally provided with a filtering tank water outlet tube which vertically penetrates through packing and is communicated with the clean water tank; a clean water tank water outlet tube is communicated between the clean water tank and the nitratlon reaction tank; a fish tank water supply tube which is communicated inside the fish tank body is arranged at the upper part of the nitratlon reaction tank; the siphon casing comprises a siphon support tube, a siphon water outlet tube and an auxiliary siphon tube which are arranged vertically and sleeved together from outside to inside in sequence; a siphon damage tube and a backwash water inlet tube which are communicated with the clean water tank respectively are arranged on the siphon support tube; the siphon damage tube is positioned above the backwash water inlet tube; a water seal tank is arranged below the siphon casing. By adopting the self-washing fish tank, functions of filtration, biological nitrification and denitrification, siphon backwash and automatic washing stopping can be achieved.

Description
