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.
SUMMARY OF THE INVENTION The object of the present invention is to provide a counterflow biological filter tank in which a filter structure is integrated with a water tank, and which facilitates automatic backwashing of the filter material and enhances filtration and cleaning effects.

The water pumping device includes a water pumping pipe and a water pump, and the water pumping pipe communicates with the water pumping tank and the water tank, and the pumping water is used to transport the water of the pumping water to the water pump. sink.
The water in the water tank is naturally filtered into the filter tank by gravity and filtered to overflow the drain.
By switching the switching valve and the water gravity action, the water of the filter tank is discharged from the top to the bottom direction, that is, the backwash water flow is formed opposite to the direction of the water flow during the filtration, and the filter is adhered by the efficient backwash wash. Impurities, scales, etc., it is necessary to remove the filter material by hand, and it is inconvenient to clean and replace the filter structure.
Moreover, the high-filter material of the grid frame forms a void and guides the dispersed water flow, so that the filtered water flow or the backwash water flow is smoother, dispersed, and activated, thereby improving the biological filtration efficiency and the cleaning effect.
The invention can prevent the water from oscillating by biological filtration, does not affect the colony of the nitrifying bacteria of the biological group, prolongs the service life of the filter material, and is environmentally friendly.
The invention can improve the shortcomings of the conventional sand bucket application physical high pressure filtration can not provide the space required for the formation of nitrifying bacteria colonies, and can not effectively filter the water quality. Because of the good biota nitrifying bacteria colonies, it can effectively nitrify organic matter to form stable water quality, provide a good living environment to enhance biological immunity to avoid diseases, effectively reduce drug use, avoid heavy metals and antibiotics and other drugs causing environmental pollution.
The invention has good water flowability, does not require a large power motor to provide a large amount of high-pressure water flow, has energy-saving effect, and uses a single water tank to reduce the heat dissipation range; and does not need to filter white cotton and physical filter materials without pores, thereby effectively reducing the amount of garbage It has the functions of energy saving, carbon reduction and environmental protection.
