A water-changing ecological fish tank with natural water purification and oxygenation

Abstract

The invention provides a water change-free ecology fish jar with naturally purified and oxygenated current; the fish jar comprises a tank, a pedestal, and a purifying oxygenation basin; the tank is the main body of the whole fish jar, and an axial section of which is in an oval shape; one end of an oval minor axis is provided with a big opening, the other end of the minor axis is the bottom of the tank, and the bottom is a concave surface; the pedestal is arranged right below the tank so as to support the tank; a water pump placing room is arranged in the pedestal, and the water pump can ensure the water circulation in the tank; the purifying oxygenation basin is arranged right above the tank, and can realize purifying and oxygenation functions through the water pump having proper outgoing water amount; the fish jar saves energy, can satisfy oxygen consumption demand of the fish of certain quantity; a vegetation zone is arranged in the purifying oxygenation basin so as to purify the water body, thus ensuring the clearness of the water body. The fish jar has water change-free function, is simple in operation, suitable in places like an office, home or a dormitory, thus providing a convenient fish farming device for fish lovers having limited time and energy, like white collars and students.

Description

technical field [0001] The invention relates to a fish tank for water body purification and oxygenation for aquaculture fish, in particular to a water-changing ecological fish tank for natural water purification and oxygenation. Background technique [0002] There are a large number of fish lovers, such as white-collar workers and students, who cannot use larger fish tanks due to limited time and space. They can only choose small fish tanks to raise a few fish. Small fish tanks are used to raise fish on desks, and the same is true for students on desks in dormitories, but the fish often die after a short period of time. [0003] At present, many small fish tanks can be provided on the market, and these small fish tanks usually have several usage methods: [0004] The first is to use small fish tanks without using any filter oxygenation equipment. This method is relatively common, but this method has the following disadvantages: [0005] 1. Since the contact between the su...

Problems solved by technology

In addition, due to the insufficient amount of dissolved oxygen, the amount of food fed is also very small, resulting in unhealthy fish, often presenting a state of "sluggish" fish, which reduces the ornamental value;

[0006] 2. Due to the lack of proper filtering equipment, the fish feces and other residues will settle at the bottom of the tank, and the fish will also stir the sediment at the bottom of the tank when swimming, which will affect the appearance

[0007] 3. Due to the poor fluidity of the water body in the tank and lack of oxygen, and the frequency of water changes is too high, it is difficult to form a good microbial environment required for fish survival, resulting in fish prone to disease and low survival rate;

[0009] 1. When the aeration pump is turned on, it will generate a certain amount of noise on the one hand, and on the other hand, it will also bring up the feces and residues at the bottom of the tank, affecting the clarity of the water and affecting the appearance

[0010] 2. Since the feces and residues in the tank need to be removed with special equipment, such as changing the water and toilet suction, it takes a lot of time on the one hand, and on the other hand, it is difficult to absorb the water because it is easily disturbed by the fish when swimming.

[0011] 3. Since the water body is easily turbid, a certain amount of water needs to be replaced frequently

[0014] 1. The position facing the inflow of water on the filter material is easily blocked by residue

This will reduce the use efficiency of the filter material, require frequent cleaning frequency, and increase the workload of fish farming

[0015] 2. Due to the need for "strong" water or air inhalation, electric energy is wasted, and the noise generated by inhalation will also affect the quiet leisure environment

[0016] 3. The oxygenation method of "spraying" water requires a larger power pump to bring more oxygen into the water body, which will also consume more power

[0017] Based on the above situation, it can be found that the filtration and oxygenation methods commonly used in small fish tanks on the market currently have problems in saving fish farming time, increasing dissolved oxygen in water, saving electricity, and maintaining water clarity. The problem
