The bottom of elevated tank 2 is communicated with the elevated tank outlet pipe 21 on filtering tank 3 top, it is provided with in described filtering tank 3 and passes vertically through the filtering tank outlet pipe 31 that filtrate connects with filtered water tank 4, the filtered water tank outlet pipe 41 bottom nitration reaction tank 5 it is communicated with on described filtered water tank 4, filtered water tank outlet pipe 42 is provided with the filling pipe connected with tap water, filling pipe is provided with moisturizing electromagnetic valve 43, and the top of nitration reaction tank 5 is communicated with the fish jar feed pipe 52 in fish tank body 1.
nullSiphon sleeve pipe 6 includes the siphon stay pipe 61 being sequentially sleeved at from outside to inside together being vertically arranged、It is siphoned off water pipe 62 and auxiliary siphon tube 63,The two ends up and down of described siphon stay pipe 61 all seal,All there is opening at the two ends of auxiliary siphon tube 63 and the two ends being siphoned off water pipe 62,The position of auxiliary siphon tube 63 upper end is higher than the position being siphoned off water pipe 62 upper end,The lower end of auxiliary siphon tube 63 is positioned at and is siphoned off water pipe 62,The side wall surface being siphoned off water pipe 62 lower end offers outlet,Auxiliary siphon tube 63 lower end and be siphoned off water pipe 62 lower end and all stretch out siphon stay pipe 61,Siphon stay pipe 61 is provided with the siphon destructing tube 611 and backwash water inlet pipe 612 all connected with filtered water tank,Siphon destructing tube 611 is positioned at the position above backwash water inlet pipe 612,The top of auxiliary siphon tube 63 is provided with from being siphoned off the wall of water pipe 62 top branch's water inlet 621 of passing through,The height of branch's water inlet 621 is less than siphon destructing tube position on auxiliary siphon tube.The lower section of siphon sleeve pipe 6 is provided with for by auxiliary siphon tube 62 be siphoned off the flashback tank 8 that water pipe 63 lower end seals, and described flashback tank 8 connects drain pipe 81.
The self-cleaning fish jar of the present embodiment also includes the inflator pump 7 by aerating pipe 71 oxygen supply in fish tank body and electric cabinet, and aerating pipe 71 is provided with check valve 72, and one end that aerating pipe extend in fish tank body is provided with aeration head 73.Electric cabinet can be used for controlling moisturizing electromagnetic valve break-make, and electric cabinet and inflator pump are arranged at the position below fish tank body.
nullWhen the present embodiment uses,Breed fish in fish tank body,This internal water of breeding fish of cylinder is according to the direction flowing shown in arrow in figure,Water of breeding fish first flows in quiet compression chamber from fish jar outlet pipe,The pressurized pump of water of breeding fish is lifted into high position distribution water tank,Filtering tank top is entered into again through elevated tank outlet pipe,Water of breeding fish when passing downwardly through filtrate indissolubility float therein fallen by media filtration,Breed fish water in filtering tank outlet pipe enters into nitrification denitrogenation tank after filtration,Owing to the biologic packing material of the bigger serface of installing in nitrification denitrogenation tank having the antibacterial carrying out nitrification and denitrification reaction,In water of breeding fish with a small amount of dissolved oxygen under conditions of,Antibacterial can carry out nitration reaction,Thus rest ammonia nitrogen substances poisonous in fish and water and be converted into nontoxic nitrate,Water of breeding fish nontoxic after nitration reaction enters in fish tank body further through fish jar feed pipe.
When the float retained on filtrate gets more and more, filtering layer blocks, water level in elevated tank and filtered water tank will gradually rise, siphon stay pipe and the water level being siphoned off between water pipe and filtered water tank synchronize to rise, when water level is increased to auxiliary siphon tube branch water inlet position, water will in auxiliary siphon tube to flow away, namely according to the direction flowing shown in arrow in auxiliary siphon tube in Fig. 2, because lower auxiliary siphon tube bottom is lived by the water seal in flashback tank, so the air between siphon stay pipe and waterline is pulled away, vacuum is formed at siphon sleeve pipe top.After being vacuum formed, the water of filtered water tank enters into bottom filtering tank by outlet pipe from top to bottom, the most from top to bottom pass through filtrate, thus upwards backwash filtrate, backwash water after backwash filtrate is according to the direction flowing shown in arrow in Fig. 2, and backwash water is first upwardly in the cavity being siphoned off between water pipe and siphon stay pipe from backwash water inlet pipe, then drains down into from the cavity being siphoned off between water pipe and auxiliary siphon tube in water sealed tank, finally discharging through drain pipe, backwash water can be used to water flowers.When in filtered water tank, water level decreasing to siphon destructing tube sucks air, rinse and stop.
For avoiding the water level of fish jar to fall a lot, the correct position on fish tank body 1 wall equipped with liquid-level switch 16, when the water level decreasing of fish jar is to time below the waterline set, automatically opens up moisturizing electromagnetic valve 42, fish jar carries out the slow moisturizing of low discharge.In backwash process, the water of loss is automatically replenished, and this process achieves automatic water-replacing.
In the present embodiment, fish jar water inlet pipe and fish jar outlet pipe can select the water pipe of a diameter of 6mm and 25mm respectively, first can buy cheap nautilus of rushing from food market and support in fish tank body, die if any fish, repurchase new fish to add, after cheap fish all survives, just represent nitrobacteria and cultivate successfully, the high-grade pet fish such as the Cyprinus carpio L. bought back from birds and flowers market can be fed.Only needing the quantitative feeding of every day one to twice, fish in fish tank body can be kept to enliven, cylinder body is clean, and in cylinder, water is clear as new, and living to the house of people, it is permanent happy to bring.The fish jar of the present embodiment comprises filtering function, biological nitrification and denitrification function, siphon backwash filtrate and automatic water supplement function, the fish jar of 500 liters, and water treatment system total energy consumption is less than 30W.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Those skilled in the art it should be recognized that; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
