Problems solved by technology

The disadvantages of this drainage method are: first, the noise is high, and the aquarium is placed in a home environment, such a large noise affects people's rest; second, the air bubbles in the water are sprayed on the filter material for filtration without being dispersed (The broken air bubbles are beneficial to increase the gas-liquid contact area and the distribution of dissolved oxygen); third, there is no effective use of gravity to filter impurities

Embodiment 1

[0042] like Image 6 A sewage backflushing filter device as shown includes a partition 17 and a housing 1 with a cavity inside, the partition 17 divides the cavity into at least two chambers, on the wall of the housing There is a water inlet hole for external liquid to enter (the hole in the side wall of the casing 1 inserted into the right end of the water inlet pipe 2 is the water inlet hole), and the chamber connected with the water inlet hole is the first chamber 5, which is tightly closed. The baffle plate adjacent to the first chamber 5 is the first baffle plate 4 , and a first gap 7 through which the liquid overflows is provided above the first baffle plate 4 . In the present invention, the sewage inlet hole is arranged on the shell wall, and the flow of the sewage is as follows: from the inlet hole to the first chamber and then overflowing through the first gap on the first partition plate, and then the next filtration process is performed; Compared with the prior art...

Embodiment 2

[0049] like Figure 7 As shown, the first chamber 5 is provided with a backflushing pipe 8 , the water inlet of the backflushing pipe 8 is connected to the water inlet hole, and the water outlet of the backflushing pipe 8 is connected to the first chamber 5 . combined with figure 2 , with Figure 7 is attached figure 2 A partial enlarged view of the first chamber 5 and the second chamber adjacent to the first chamber, but with attached Figure 7 The structure in the first chamber is different from the attached figure 2 The structure of the inner first chamber.

Embodiment 3

[0051] like image 3 shown, image 3 Yes figure 2 In the schematic diagram of the middle A direction, the difference between the embodiment 3 and the embodiment 2 is that the recoil pipe 8 of the embodiment 3 includes a tee pipe 801 and two transverse pipes 802, and the tee pipe 801 includes an inlet and two The two horizontal pipes 802 are respectively inserted into the two outlets of the three-way pipe 801; the water outlet of the backflushing pipe is set on the horizontal pipe, and the liquid flows from the inlet of the three-way pipe. into the cavity from the water outlet on the cross tube. like Figure 4 As shown, the water outlet is a through hole 25 opened on the horizontal pipe. The opening of the through hole one 25 faces upward. This facilitates the formation of a static flow sedimentation layer under the horizontal pipe, and the overflowing clean water above the horizontal pipe. At least two through holes are included, and the through holes are evenly distrib...

Abstract

The invention relates to a filtering device for an aquarium, in particular to a sewage back-flushing filtering device. The sewage back-flushing filtering device comprises a partition plate and a shell with an inner cavity, wherein the inner cavity is divided into at least two chambers by the partition plate; a water inlet hole through which external liquid enters the shell is formed in the wall of the shell; the chamber communicated with the water inlet hole is a first chamber; a partition plate close to the first chamber is a first partition plate; a first gap through which liquid overflows is formed above the first partition plate. In the prior art, water in a water tank is drained for filtration in a spraying way, and loud noise is produced during spraying; compared with the prior art, the device has the advantages that noise is greatly reduced, and good muting effects are achieved.

Description

technical field [0001] The invention relates to an aquarium filter device, in particular to a sewage recoil filter device. Background technique [0002] like figure 1 As shown, the aquarium usually includes two parts, respectively a fish tank 11 and a casing 13 arranged below the fish tank, a filter tank is placed in the box body 13, and the filter tank includes a housing 1 with a cavity in it, and the filter tank is used to filter the fish tank. The sewage in the tank is filtered and purified before being discharged into the fish tank. In the prior art, the water in the fish tank is sprayed on the filter material 6 above the filter tank through the nozzle 14, one end of the nozzle is connected to the bottom of the fish tank, and the other end is sprayed towards the filter material 6 (when spraying, water contacts with air to increase dissolved oxygen). The disadvantages of this drainage method are: first, the noise is high, and the aquarium is placed in a home environment...
