Description

Filtration system for aquaculture tanks

The present invention relates to a filtration system for an aquaculture tank, in particular to a high electric field generated by an anode grid and a cathode plate to induce plasma power generation, and high-speed electrons generated during the discharge process collide with solution molecules to generate free radicals. The free radicals react to generate ozone, and electrons, free radicals and ozone all have high oxidizing ability. Once they come into contact with pollutants, they can be oxidized and decomposed to achieve a filtration system that removes pollutants and purifies water.

According to the general aquarium, a good filtration system is needed to achieve a balanced ecological environment, and most aquarium lovers know that the water in the aquarium must establish a good nitrification system, that is, to cultivate a nitrification system. Bacteria can digest and decompose the ammonia contained in the water and oxidize it to nitrite, and the highly toxic ammonia is converted into the less toxic nitrate. In short, the toxicity in the water is decomposed and diluted. Therefore, if you want to raise fish, you must first raise the water, and raising water is usually through a filter device. In addition to filtering dirt and impurities, it is also used to cultivate nitrifying bacteria, so that an ecological balance that is close to nature is established in the aquarium. nitrification system.

A simple built-in or external filter device for general aquariums, such as the Chinese Patent No. 471261, the device is mainly divided into a filter tank and a primary filter chamber containing white cotton, biochemical cotton or other filter materials, a guide A flow chamber, a second filter chamber containing biochemical filter materials such as biochemical balls or activated carbon, and several spaces such as a pumping chamber, and the lower end of the partition plate between the primary filter chamber and the diversion chamber A flow port is formed, and the upper end of the partition plate between the guide chamber and the second filter chamber is lower than the upper end of the partition plate between the primary filter chamber and the guide chamber, and the second filter chamber and the suction chamber, and at the same time On the upper end of the front side plate at the primary filter chamber, there is an overflow port for the water in the aquarium to overflow, and the lower end of the partition plate forms a flow port that communicates the second filter chamber with the bottom of the pumping chamber; , A pump is installed in the pumping chamber, so that the filtered water is pumped back into the aquarium through the pump, so that the water in the aquarium can achieve the purpose of circulating, filtering and purifying.

The filter material in the initial filter chamber of the above-mentioned filter device is usually to filter the fish feed, fish feces or other impurities with large particles in the water first, and then enter the guide chamber through the flow port, and then the water flows upward from the guide chamber and crosses the water. It flows through the baffle and enters the second filter chamber, allowing the water after primary filtration to pass through the filter material in the second filter chamber. In addition to the secondary filtration of small or finely divided feed, feces and other impurities, the water also passes through the biochemical filter material to cultivate nitrification. bacteria, so that the bad substances in the water can be decomposed, and then a good nitrification system in the aquarium is established. Finally, the pump in the pumping chamber pumps the filtered water layer by layer back into the aquarium, and so on.

However, the pumping speed of the pump should not be too fast, so the flow of water in the water filter tank is also relatively gentle, so it is easy to cause the above-mentioned fine feed, feces and other impurities to sink in the bottom of the primary filter chamber and the second filter chamber and it is difficult to discharge along the water flow. , Over time, it will corrupt and produce a large amount of toxins, which makes it difficult for the nitrification system to quickly and effectively decompose toxins, and then return to the aquarium to filter water with toxins, which will cause the farmed fish to become sick or even die.

However, none of the current aquarium filters on the market can filter, deodorize and kill bacteria at the same time. In addition, the size of the aquarium and the amount of water in the corresponding aquarium are also very different. If the filtration efficiency cannot correspond to the amount of water, the filtration is invalid. Therefore, usually users can only Choose to replace a larger filter to deal with it, but the space limitation also makes the filter always have enough problems.

Therefore, the main purpose of the present invention is to provide a plasma power generation induced by the high electric field generated by the anode grid and the cathode plate, and the high-speed electrons generated during the discharge process collide with solution molecules to generate free radicals, and some of the free radicals undergo The reaction generates ozone, and electrons, free radicals and ozone have high oxidizing ability.

Wherein, the anode grid is covered on the outer wall of the cylinder, and the anode grid is enclosed and fixed on the cylinder by a protective cover.

When used in this way, the original water body in the aquarium body is pumped into the first communication pipe and then into the accommodating space of the cylinder body by the function of the first water pump, and when the original water body gradually rises, and continues When flowing through the cathode plate, the original water body will inject water into the space between the cathode plate and the wall of the cylinder, and the power supply can be connected to the cathode plate and the anode grid, then the original water body between the cathode plate and the anode grid , will be subjected to the effect of plasma to produce water purification, deodorization, and sterilization. The high electric field generated by the anode grid and the cathode plate induces plasma power generation, and the high-speed electrons generated during the discharge process collide with solution molecules to generate free radicals, which are partially free. The radicals are then reacted to generate ozone, and electrons, free radicals and ozone all have high chemical ability. Once they come into contact with the water body, they can be oxidized or decomposed to achieve the effects of water purification, deodorization, and sterilization, and become a purified water body. It can be used in today's aquarium filtration system, and it is enough to solve the problem that the current aquarium filters on the market cannot simultaneously filter, deodorize, and kill bacteria. effect.
