Linear reciprocating siphon fish excrement discharging device

Abstract

The invention discloses a linear reciprocating siphon fish excrement discharging device. The linear reciprocating siphon fish excrement discharging device comprises a fish culture tank, a water supplementing normally-closed electromagnetic valve, an electric fish feeder, an automatic fish excrement concentrating obtuse angle or arc-shaped fish tank bottom and an automatic control circuit. The linear reciprocating siphon fish excrement discharging device is characterized by further comprising a plurality of downward parallel siphon fish excrement holes 13 close to fish excrement and a linear reciprocating siphon fish excrement longitudinal extension pipe 14 which are in linkage to do linear reciprocating motion, and the reciprocating stroke is several centimeters, so that the length of thesiphon fish excrement reaches several meters. When a motor 18 and a siphon fish excrement discharging water pump 20 are started once to do linear reciprocating motion, the device works for several seconds once, the plurality of downward parallel siphon fish excrement holes 13 close to the fish excrement can rapidly suck in the fish excrement precipitated in an automatic fish excrement concentrating area 12, and the fish excrement is directly discharged out of a fish culture water system through a fish excrement mixed water discharging connector 21. The heavy burden that 100% of fish excrementis filtered by circulating water is solved from the source, the trouble of daily frequent cotton washing and water changing is avoided, and the fish culture maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of fish tanks and aquariums, and relates to a linear reciprocating siphon fish excrement discharge device. Background technique [0002] Existing fish tank and aquarium device mainly exist following deficiency: [0003] In the prior art: automatic centralized fish feces discharge and siphon circulating water filtration aquarium, it is characterized in that: the automatic siphon fish feces discharge device includes a siphon fish feces longitudinal extension tube, and the siphon fish feces longitudinal extension tube is There are a plurality of siphon fish feces holes that are parallel and close to the fish feces, and the longitudinal extension tube of the siphon fish feces is arranged above the automatic concentration area of ​​fish feces, because the longitudinal extension tube of the siphon fish feces is fixed, Each siphon fish hole can only siphon fish in a fixed range, and the efficiency of the siphon fi...
