AI Technical Summary

Technical Problem

Traditional filtration devices suffer from problems such as complex disassembly and assembly that easily damage nitrifying bacteria communities, lack of positioning structure in stacked filter boxes that are prone to misalignment, and fixed overflow ports that cannot dynamically adjust hydraulic retention time, resulting in low water purification efficiency and inconvenient maintenance.

Method used

It adopts a modular tank design, adjustable water level, multi-level positioning structure and embedded foam interception function to achieve dynamic hydraulic control and precise filter media contact. Combined with external aquarium filtration device and spray nozzle aeration, it forms a highly efficient and low-maintenance water quality management system.

Benefits of technology

It improves filtration efficiency, reduces maintenance costs, enhances the stability of biological systems and water purification effects, adapts to different aquaculture load changes, and avoids energy waste and filter media contamination.

Abstract

The novel filtering device comprises a right-side tank body, a middle tank body and a left-side tank body which are divided by partition plates, a water inlet is formed in the bottom of the right-side tank body, and the top of the right-side tank body controls the height of an upper communication opening through a liftable water level adjusting piece to achieve dynamic hydraulic retention time adjustment; filter units with positioning structures are stacked in the middle tank body, and a lower communication port is formed in the bottom of a partition plate between the middle tank body and the left tank body; the left tank body integrates a water pump and a water spray nozzle to form a circulation path and increase the dissolved oxygen content of the water body. The fish tank comprises a tank body and a vertical notch formed in the top end of the tank body and used for intercepting floating foam on the water surface, and the novel filtering device is arranged on one side of the tank body. According to the utility model, through the design of modularized quick release, dynamic water level control, accurate positioning, floating foam interception and the like, the problems of complicated maintenance, insufficient filtration, poor load adaptability and the like of a traditional filtering device are solved, high-efficiency and low-maintenance water quality management is realized, and the water quality management device is suitable for aquaculture and fish tank scenes.
