Description

A double-layer purification semi-open small desk fish tank

technical field

The invention relates to a desk fish tank, in particular to a double-layer purified semi-open small desk fish tank.

Background technique

At present, common fish tanks on the market are divided into two categories, one is a fish tank for large-scale places; the other is a fish tank for families, offices and other places. Among them, the fish tanks used in places such as homes and offices are relatively large in size and occupy a large space, but specific places often cannot meet this condition. Moreover, currently on the market, the two common types of fish tanks need to be equipped with certain special oxygenation and filtration devices in order to realize the oxygenation and filtration functions.

However, in many places, limited by the local environment, it is inconvenient to use the two commonly used types.

At present, the common aeration device on the market is realized by the aeration pump; the aeration pump presses the air "forcibly" into a certain distance below the liquid surface, and the air bubbles emerge from the sand and come into contact with the water body , to achieve oxygenation function. Common filter devices on the market are mainly composed of a water pump and a filter box: the water pump pumps water into the filter box placed on the upper end of the fish tank, and after being simply filtered by the flat filter cotton, it flows into the fish tank below to realize the filtering function . A "three-in-one" submersible pump has also appeared on the market, which integrates water pumping, oxygenation and filtration to achieve oxygenation and filtration. Although, in the above-mentioned device, all can realize oxygenation and filter function, still, there are following deficiencies:

1. As far as the oxygenation device realizes the oxygenation function: the air is "forcibly" pressed into a certain distance below the liquid surface of the fish tank, so that the air bubbles come out to contact the water body. However, in this way, the bubbles generated are extremely large and come out extremely fast, not only the contact area with the water body is small, but also the contact time is short, and the oxygenation effect is poor. At the same time, when the bubbles are rising, they wash up the residue at the bottom, causing secondary pollution to the water and reducing the ornamental value of the scenery in the fish tank; and the working noise of the aeration device is loud, consumes electric energy, and generates electromagnetic pollution. Due to the low dissolved oxygen in the water body, the food intake of ornamental fish is reduced, which affects the conversion rate of food. All of these will lead to a decrease in the resistance of ornamental fish, and they are susceptible to disease. In severe cases, large-scale infection and death may occur.

2. As far as the filtering device realizes the filtering function: the method adopted is to use the water pump to pump the water body from the bottom to the top, and realize the filtering function through the flat filter cotton. But in this way, the filter cotton is easy to be blocked, and the cleaning cycle is short; the water pump cannot "automatically" pump out all the residue at the bottom, and when the water pump pumps the water body, the residue is crushed, causing secondary pollution to the water.

3. As far as the circulation system is concerned: the water is pumped into the filter box placed on the top of the fish tank with filter cotton, and then drips down. The realized function is single.

4. As far as the ecological nitrification system is concerned: in the entire fish farming device, only the tiled filter cotton placed in the filter box above the fish tank can provide the main breeding place for nitrifying bacteria. However, due to the accumulation of residues in this place, the lack of dissolved oxygen, and the low reproduction rate of nitrifying bacteria, the water body is prone to turbidity, and the cleaning cycle is short, which is not conducive to the growth of ornamental fish. The resistance of ornamental fish decreases, and they may get sick or even die.

In a word, the fish farming devices currently on the market all have the disadvantages of low dissolved oxygen, poor filtering effect and short cleaning cycle, so they need to be improved.
