Abstract

The utility model relates to a water filtering device for an aquarium, which mainly comprises a forced type filtering main box and a physiochemical wheel, wherein a horizontal notch of the side wall of the main box is connected with a water outlet groove to form a water outlet channel with filtering cycle water flow. The physiochemical wheel is adjacent to the water outlet channel, and the height of one fifth to one second of the physiochemical wheel is dipped in water. The physiochemical wheel can slowly rotate under the pushing of filtering cycle water flow, and organic matters in water are adsorbed in the process of the rotation of the physiochemical wheel. Then, nitrifying bacteria are prompted to propagate largely through a rotating and aeration mode and gradually flow back to the aquarium. The filtering device can fully filter dirt impurity in water in a force mode, and keep the stable water quality for a long time.

Description

A kind of aquarium filter

The utility model relates to a kind of device that the water of culturing in the aquarium is filtered.

The traditional filtering device that is applied to culture aquarium mainly contains two kinds of frame modes.First kind is open flute profile filter, during filtration current can be in biochemical cotton abundant aeration, help nitrifying bacteria and breed in a large number, but current are in the flow regime of nature in filter process, can't be with the thoroughly filtering of the assorted dirt of the dirt in the water, filter effect is relatively poor; In order to address this problem, people have adopted the outer filter vat of a kind of sealed cylinder again, its structure more complicated, current are in the airtight container and are flowed by the suction pump forced circulation during filtration, therefore flow through the multilayer filter material, the filtering effect of this filter vat is better, but since in filter process current be in sealing state can't aeration, make nitrifying bacteria be difficult to a large amount of breedings, water quality can't keep stable for a long time.Its band can wear out gradually and produce drainage in addition.

The purpose of this utility model provides a kind of filter, and it can carry out mandatory abundant filtration to the water of culturing aquarium, can produce nitrifying bacteria in large quantities again simultaneously in the cyclic process of filtered water stream, makes water quality keep stable for a long time.

The utility model can be realized like this: it comprises water pump, main body case, the delivery port of water pump is communicated to the water inlet of main body case bottom, the main body case middle part is fixed with the biochemistry filtered basket of filling the biochemistry filtered material of each layer, the outside of biochemistry filtered basket sidewall and the inner face of main body case fit tightly, and a plurality of water apertures of crossing are arranged at the bottom of the basket of biochemistry filtered basket; Be provided with breach on a sidewall on main body case top, the breach front is connected with effluent trough and forms aquaporin; Near breach base or effluent trough bottom surface rotating biochemical wheel is installed, has biochemical wheel freely to rotate required radial clearance between the two, biochemical wheel contains microporous absorbent material.

Fig. 1 is the main body case of first embodiment of the utility model and shape, the organigram of effluent trough;

Fig. 2 is the vertical view of first embodiment when being affiliated on aquarium;

Fig. 3 is that Fig. 2 is along A-A line cutaway view;

Fig. 4 is that Fig. 2 is along B-B line cutaway view;

Fig. 5 is the cutaway view of another embodiment of the utility model.

Below in conjunction with drawings and Examples the utility model is described further:

Embodiment 1, the shape of main body case 1 and structure as shown in Figure 1, water inlet 11 is arranged at its bottom, has the Cross slat v notch v on the sidewall on top, breach is connecting effluent trough 4, the effluent trough side wall upper part has the rotating shaft axle bed 41 that can lay biochemical wheel.Fig. 2, Fig. 3 and shown in Figure 4, the delivery port of water pump 5 is connected with water pipe 6, and the delivery port of water pipe 6 feeds header tank 7, a header tank 7 and main body case 1 a shared sidewall, both are communicated with by the water inlet 11 of main body case bottom.Biochemistry filtered basket 2 is fixed on main body case 1 middle part, is supported with cushion block 8 below, and sidewall 21 outsides of biochemistry filtered basket and the inner face of main body case 1 sidewall fit tightly, at the bottom of the basket of biochemistry filtered basket 23 and basket lid 24 be covered with the latticed water aperture of crossing.The periphery support 32 and the rotating shaft 31 of biochemical wheel are connected and fixed and are integral, and support 32 internal supports and contained microporous superabsorbent fibrous material 33.Biochemical wheel 3 is placed on the axle bed 41 of effluent trough free to rotate by its rotating shaft 31, the rotating shaft 31 of biochemical wheel is parallel to the breach base 12 of main body case, between the radial edges of biochemical wheel 3 and the bottom land of effluent trough 4 narrow gap is arranged, narrow gap is also left in the axial two sides of biochemical wheel and the two side of effluent trough.Whole filter relies on hook 10 to be suspended on the aquarium sidewall 9, and effluent trough 4 is positioned at above the aquarium sidewall 9, and the outlet of effluent trough 4 is towards aquarium.

When the water to aquarium filtered, current from bottom to top covered biochemistry filtered basket 2 by water pump 5 suction header tanks 7 lentamente through main body case water inlet 11.Because biochemistry filtered basket 2 fits tightly with main body case 1, current all are forced to pass through from biochemistry filtered basket 2 basically, and the dirt foreign material in the water are filtered substantially all that the biochemistry filtered material 22 of each layer filters out in the basket, reach the filter effect of sealed filter vat.After the water level in the main body case 1 covers breach base 12, current will flow to effluent trough 4, promote biochemical wheel 3 rotations.Because narrow gap is only left with biochemical wheel edge in the effluent trough bottom surface, current are blocked, and water level raises again again, have 1/5th to 1/2nd highly under water until the biochemistry wheel.The fibrous material 33 of biochemical wheel 3 is the organic matter in the adsorbed water in large quantities, allows nitrifying bacteria adhere to breeding; And the rotation of biochemical wheel can make the nitrifying bacteria that adheres to fully exchange with airborne oxygen by the mode of rotating aeration, helps the raised growth breeding of nitrifying bacteria more, and gradually along with circulating water flow flows back to aquarium.

Embodiment 2, see accompanying drawing 5, and biochemical wheel is placed on main body case inside and near water outlet breach base, biochemical wheel is polygon, and rotate between formed peripheral curved track and the breach base on its corner angle limit a narrow gap.The sorbing material 33 of this biochemistry wheel adopts sponge class material, because the micropore quantity of sponge class material is more intensive, can more effectively adsorb organic matter.Top at main body case also is provided with top cover 13.

The utility model has the following advantages and effect:

1. because biochemical wheel adopts the rotation aeration mode, can make filtered water stream in cyclic process Produce a large amount of nitrobacterias, make water quality keep for a long time stable.

2. filter of the present utility model has adopted the Cross slat v notch v front of main body case to connect the structure of effluent trough, makes circulating water flow after flowing through filter basket, through expansions of tile in effluent trough of Cross slat v notch v, and promotes biochemical the wheel and rotates.Adopt said structure to have the advantage of two aspects; The first makes current wideer with the contact-making surface of biochemical wheel, and absorption is organic more to help biochemical wheel, allows more substantial nitrifying bacteria growth and breeding; It two is make whole filter simple and compact for structure, has reduced manufacturing cost, is convenient to the operation operation.

The utility model can be earlier by water pump with water suction header tank, flow directly into main body case then, flow back to aquarium by effluent trough at last.In whole current forced circulation process, do not have to have the weak link of outside aquarium, leaking easily, overcome the shortcoming that conventional seals formula filter vat leaks easily.
