System for feeding aquatic organisms and cleaning unit for water tank

Abstract

An aquarium system for aquatic organisms capable of easily performing maintenance of a purifying device and a circulation pump, etc., and downsizing a purifying zone is provided. The system of the present invention includes an aquarium 1, a partition wall 2 dividing the aquarium into a nurturing zone 11 and a purifying zone 12, a circulation pump 81 for circulating water between the nurturing zone 11 and the purifying zone 12, and at least one purifying device selected from a filter 50 for filtering water by making the water pass through a filtering material, a protein skimmer 70 for removing proteins contained in the water by making the proteins adhere to air bubbles, and an ultraviolet light irradiator for sterilizing the water by irradiating ultraviolet light to the water. The circulation pump and the at least one purifying device constitute a unit member. The unit member is mounted on a mounting frame to thereby form a purification unit 3. The purification unit 3 is accommodated in the purifying zone 12 in a removably inserted manner in a state in which the unit member is mounted on the mounting frame.

Description

technical field [0001] The present invention relates to an aquaculture system of an internal purification method in which a purification device such as a filter is arranged in a water tank, and a purification unit for the water tank. Background technique [0002] When aquarium fish are raised in an aquarium, a filtration device is generally installed in order to keep the water in the aquarium clean. [0003] As a system for filtering water in a water tank, an external filtration system in which a filter device is provided separately from the water tank, an internal filtration system in which a filter device is incorporated in the water tank, and the like are known. [0004] For example, as shown in the following patent documents 1 and 2, the water tank of the ornamental fish breeding system of an internal filter type is divided into a breeding area and a filtering area. In addition, the filtration area is divided into a plurality of water passage chambers communicating with...

AI Technical Summary

Problems solved by technology

Therefore, there is a problem that, in addition to the installation space of the parts, a work space for taking out and putting in the parts is required in the filtering area, and accordingly the filtering area becomes larger, resulting in an increase in the size of the entire breeding system.

[0008] In addition, if the working space in the filter area is reduced, it will be difficult to take out and put in parts, and troublesome problems such as maintenance work will arise.
