Description

Bio-helix filtration device and aquaponics system for aquaponics {FILTRATION APPARATUS FOR AQUAPONICS AND AQUAPONICS SYSTEM USING SAME}

The present invention relates to a bio-helix filtration device and an aqua phonics system for aqua phonics.

Aqua phonics is a production method that combines fish farming and hydroponic cultivation of plants, and it is a circulation method in which the water used for aquaculture is used for aquaculture after hydroponics, and water is circulated so that both aquaculture and crop cultivation can be used. It is an eco-friendly production method that minimizes the impact on the environment as it is used.

Aqua phonics creates an environment in which fish species and plants can coexist. In aquaculture, the excrement that fish eats and discharges pollute the water, so a continuous water purification device is required. It can purify water by absorbing fish excrement as nutrients.

As the prior art for the water purification device and heat exchange device of the conventional aquaponics device, Patent Publication No. 10-1061439 (filter device for aquarium), Patent Publication No. 10-0957173 (water purification device for aquarium) and Registered Patent Publication No. 10-1247648 (a water temperature control device for a fish storage tank) has been proposed.

Registered Patent Publication No. 10-1061439 includes a tubular case, a pump that sucks water from an aquarium and discharges it to the top of the case, a filter installed inside the case and filters foreign substances contained in the water discharged from the pump. , It is a structure that includes a skimmer cylinder connected to the top of the case through a connection pipe and collecting and discharging floating substances floating along with air bubbles, and a discharge pipe connected to the bottom of the filter of the case and discharging the water that has passed through the filter toward the aquarium. . However, the water in the aquarium is sucked in by a pump installed in the aquarium, filtered through a filter in the case, sent to the aquarium, and the bubbles generated in the above process are sent to the skimmer to be discharged. It is a filtration device that purifies the water and has a disadvantage in that the filtration capacity is limited and the filtration efficiency is lowered, and the structure of the discharge of bubbles discharged during the filtration process is also unstable, and thus there is a problem such as insufficient purification and filtration process of the aquarium water.

Registered Patent Publication No. 10-0957173 (Water purification device for aquariums) is installed in a case divided into a bubble removal zone, a water purification zone, and a flow control zone, and in a bubble removal zone, and floating substances such as proteins along with bubbles contained in water It is installed in the flow control pipe that connects the bubble removal device to the bubble removal zone and the flow control zone, and the water purification zone, and passes through the bubble removal device to secondarily purify the water flowing in the state where bubbles and suspended substances are removed. It is a structure that includes a gravity filter device that removes foreign substances such as solids.
