Description

Counterflow biological filter tank

The present invention relates to a filter tank, and more particularly to a counterflow biological filter tank.

In today's busy society, people usually engage in various leisure activities. For example, many people will set up fish tanks indoors to raise water and plants, or raise fish or plant water plants as a profession, by watching the fish Take a leisurely swim in the aquarium to relax your nervousness.

When raising fish, the water quality control of the fish tank is an important issue to raise the fish. The existing fish tank is usually provided with a filter material on one side, and the water in the fish tank is filtered through the filter material to filter impurities and scale in the water. Then, return the clean water to the water tank and repeat the cycle to keep the water in the fish tank clean.

However, after filtering the filter material for a certain period of time, it will adhere to a lot of impurities, scales, etc., and it is necessary to take out the replacement of the filter material from time to time, which is inconvenient to clean and inconvenient to replace. It often takes a lot of money to control the quality of the fish tank. Labor, time and spirit, and a little carelessness, may make the place where the fish tank is placed wet or flooded, or even cause the fish to die. If the fish is quite expensive, it will cause more damage.

Moreover, the traditional filtration system needs to change the filter white cotton frequently. Otherwise, the accumulation of impurities and dirt will cause a blockage, and the water in the filter tank overflows, causing the water to be everywhere! In this way, the filter white cotton is often replaced to produce a large amount of garbage, which does not have the functions of energy saving, carbon reduction and environmental protection.

Please refer to the Taiwan Patent No. M420175, which is additionally installed outside the aquarium. The industry is often referred to as a high-pressure filter sand drum, which uses the high-pressure power of the pumping motor to make a finer material (such as quartz sand). The filter medium, without pores, applies physical high-pressure filtration according to the principle of high-density material. Forcing and pumping water into the filter for filtration and purification procedures can only block the dirt in the water, and the filter material can not provide the retention of nitrifying bacteria colonies. It is not effective to filter water quality by biological action.

It has at least the following disadvantages:

1. Applying motor pumping to form high pressure filtration, which is quite energy-intensive and environmentally friendly.

2. Application of motor pumping is easy to water quality oscillation, affecting the colony of nitrifying bacteria in the biota, and destroying the biological ecology of the aquarium.

3. The filter is usually fine sand/sand, the gas permeability is poor, and the organic matter will accumulate heavily, causing the blockage to be discharged, resulting in a high motor failure rate.

4. The filtering structure is complex, costly, occupying space and destroying beauty.

In addition, the existing aquarium and the filter material of the patent are densely packed in the filtering space, which causes the water flow in the filtering space to be fluent and dispersible, and looks like dead water, which affects the filtering and cleaning effect, especially The flow of water near the lower filter material is more fluent and dispersible.

Therefore, the filtration structure of the current aquarium is still not ideal, and it is necessary to improve it.

Therefore, the present inventors have been working on the design and development of products for many years, as well as actively researching and developing ideas, and through numerous practical tests and experiments, the present invention has been produced.
