Description

A kind of fish tank water EGR

Technical field:

A kind of fish tank water EGR of the utility model, belongs to aquaricullure water treatment technology field.

Background technology

Breed fish and first support water, become the experience that aquarist is generally acknowledged.It is most important how in the family " to support " that a cylinder is limpid, the water of nonhazardous seems.Family breeds fish and is different from fish farm and breeds fish, and family's Water space of breeding fish is narrow and small, and requires water quality as clear as crystal, is convenient to view and admire.Breeding fish in fish farm is in order to make fish Fast Growth, while having professional fish man-hour, supervises water quality, and water body is roomy, is suitable for fish and grows up.Also there is the advantage of oneself but family breeds fish, such as water temperature control, not affected by blowing and raining etc., also have family to breed fish because the water yield is less, be convenient to water quality and observe and medicine control.Family breeds fish and water will be supported and be unable to do without fish tank water EGR and filtering and purifying, in prior art, there is fish jar filtering product, as Granted publication number provides a kind of filter of the sandwich construction that is placed in fish jar top for the utility model patent of CN2680012Y, this filter is by the wire ball in multiple filter cartridges of its inside, scouring pad, wire netting, medical stone, the segmentation that active carbon carries out successively fish tank water is filtered, although play certain filtration, sterilization, oxygenation, increase micro-effect, but still can not fundamentally solve the limpid and water-soluble oxygen amount that water quality keeps the long period, and need frequently change water, and lack attractive in appearance, do not there is sight.And other similar fish jar in the market, pool water within filters, cleaning manure exists following not enough: 1, overflow height is at least 2 centimetres of left and right.2, overflow height is large, just requires the volume that is filled with water of end filter pocket large.3,, under fish jar when water, there is rustlingly rustlingly noise.4, volume greatly, not attractive in appearance, uneconomical.

Utility model content

The purpose of this utility model is to provide a kind of fish tank water EGR, and overflow height is low, completes into the process of water draining and does not have noise, not only attractive in appearance, and economical.

The technical scheme that fish tank water EGR of the present utility model adopts is:

A kind of fish tank water EGR, this device has end cylinder and is arranged on the fish jar of cylinder top, the end, is provided with purifier 4, cylinder built-in water pump in the end in end cylinder; The outlet pipe 2 of fish jar comprises outer tube 9 and inner sleeve 10, and the end cover of outer tube 9 is loaded onto cap 1, and upper cap 1 has hollow out 11, and the height of hollow out 11 is 2mm left and right, and inner sleeve 10 is communicated with the water inlet pipe 3 of end cylinder through the lower water perforate of fish jar bottom; One end of fish jar water inlet pipe 5 is connected with the purge outlet of purifier 4, and the other end of fish jar water inlet pipe 5 is connected with dual non-return insurance combination valve 7 and rotating fish excrement purging dish 8, and rotating fish excrement purging dish 8 is arranged in the upper water inlet of fish jar bottom; Dual non-return insurance combination valve 7 cleans delivery port 6 with fish jar and is connected.

Preferably, this purifier 4 is made up of electrocoagulation, electroxidation and filter course.

In fish tank water EGR of the present utility model, owing to having adopted the combination design of outer tube 9 and inner sleeve 10 and upper cap, first can be by the efficiency of siphonage capable of increasing water discharge capacity and filtration, simultaneously, because outer tube 9 and inner sleeve 10 all fill water in siphonage process, complete into the process of water draining and do not have the sound, thereby eliminated rustlingly rustlingly noise, not only attractive in appearance, and economical and practical.

Brief description of the drawings:

Fig. 1 is the structural representation of fish tank water EGR of the present utility model;

Fig. 2 is the outlet pipe 2 top schematic cross-sections of fish tank water EGR of the present utility model.

Embodiment:

Now by reference to the accompanying drawings the utility model is described further.

As shown in Figure 1, fish tank water EGR of the present utility model has end cylinder and is arranged on the fish jar of cylinder top, the end, in end cylinder, deposit a certain amount of water, in end cylinder, be provided with purifier 4, this purifier 4 is made up of electrocoagulation, electroxidation and filter course, also can be to put water purifier, the built-in water pump of end cylinder at the bottom of the EOA electrocoagulation of extensive use on market.The outlet pipe 2 of fish jar comprises outer tube 9 and inner sleeve 10, outer tube 9 bottoms are communicated with fish jar, and the upper end cover of outer tube 9 is loaded onto cap 1, and upper cap 1 has hollow out 11, the height of hollow out 11 is 2mm left and right, and inner sleeve 10 is communicated with the water inlet pipe 3 of end cylinder through lower water perforate.The water inlet pipe 5 of fish jar is connected with the purge outlet of purifier 4, and the other end of water inlet pipe 5 is connected with dual non-return insurance combination valve 7 and rotating fish excrement purging dish 8, and rotating fish excrement purging dish 8 is arranged in the upper water inlet of fish jar bottom.Meanwhile, dual non-return insurance combination valve 7 is connected with fish jar cleaning delivery port 6.After water pump is opened, water level in fish jar just can rise, water level in outer tube 9 (bottom is communicated with fish jar) rises along with the rising of the water level of fish jar, outer tube 9 tops have been set with upper cap 1, because it is the hollow out 11 of 2 millimeter that upper cap 1 medium position has drop, in the time that outer tube 9 inside and outside water levels rise to the hollow out 11 of upper cap 1, on partition, in cap 1, be connected with outer air, simultaneously, water level inside and outside outer tube 9 is suitable for reading higher than inner sleeve 10, water under the effect of gravity by inner sleeve 10 underflows, the air of taking away in inner sleeve 10 along with the underflow of water forms siphonage, after siphon forms, fish jar water outlet just rolls up and is greater than the output of end cylinder water pump, now, in fish jar, water level sloping portion exposes the hollow out 11 of cap 1, there is air to enter inner sleeve 10 simultaneously, at the interior formation air-water mixture of inner sleeve 10, inner sleeve 10 internal flow proportions are declined, along with inner sleeve 10 internal flow proportions decline, the also corresponding minimizing of fish jar outlet pipe 2 water yields, when fish jar outlet pipe 2 water yields reach a kind of dynamic equilibrium when cylinder water pump output equates the end of with, water in fish jar is received in end cylinder endlessly like this, and then be recovered to after filtration in fish jar, so go round and begin again.

Hollow out 11 drops in upper cap 1 are designed to 2 millimeters, object is that the water yield in order to make fish jar suction from end cylinder is only the water yield of 2 millimeters of height of fish jar, just can reach the siphonage of outer tube 9 and inner sleeve 10, can greatly reduce like this water yield that prestores in end cylinder, the volume of end cylinder can be done littlely, reach object economic, attractive in appearance.The combination design of outer tube 9 and inner sleeve 10 and upper cap, can form the object of siphonage, first can be by the efficiency of siphonage capable of increasing water discharge capacity and filtration, simultaneously, because outer tube 9 and inner sleeve 10 all fill water in siphonage process, complete into the process of water draining and do not have the sound, thereby eliminated rustlingly rustlingly noise.

The foregoing is only a kind of embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
