System for feeding aquatic organisms and cleaning unit for water tank

Abstract

Provided is a system for feeding aquatic organisms in which the maintenance of a cleaning device, a circulating pump and so on can be easily conducted and the size of a cleaning zone can be reduced to give a compact device. A system comprising a water tank (1), a partition wall (2) for dividing the water tank (1) into a feeding zone (11) and a cleaning zone (12), a circulating pump (81) for circulating water between the feeding zone (11) and the cleaning zone (12) and one or more cleaning devices selected from among a filtration device (50) by which water is allowed to penetrate through a filter material and thus filtered, a protein skimmer (70) by which proteins contained in the water are adhered to bubbles and thus removed and an ultraviolet light irradiator by which the water is sterilized by ultraviolet light irradiation. The circulating pump and at least one cleaning device constitute components of a unit. These unit components are loaded on a load frame to construct a cleaning unit (3). As the unit components are loaded on the load frame, the cleaning unit (3) is put in the cleaning zone (12) in an insertable / ejectable manner.

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.
