Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a polluted water filtration device, and in particular, it filters polluted water such as an aquarium for live fish, industrial wastewater, etc. to make it pollution-free or low-pollution and re-use it as clear water. It depends on the device used.

[0002]

2. Description of the Related Art Conventionally, as a device for filtering contaminated water, there are roughly classified an open permeation filtration type, a forced filtration type, and a multi-tank type.

The open osmosis filter type is one in which polluted water is poured over the filter material put in the container and the filter material is permeated to filter the polluted water and then drained from the lower part of the container. Met.

In the forced filtration type, the filtration material is filled in a sealed container provided with an intake port and a drain port, and the contaminated water forcibly taken in through the intake port is allowed to pass through the filtration material. It was filtered into clear water and drained from the drain.

In the multi-tank type, a precipitation tank and a filtration tank are provided separately,
First, a large amount of pollution is settled in the settling tank, the sludge water after the precipitation is poured into the filtration layer, and then, like the open osmosis filtration type, the polluted water is poured from the top of the filtration material in the container to filter the filtration material. The permeated water was filtered to remove the contaminated water and drained from the lower part of the container.

[0006]

However, in the open permeation filtration type, since the filtered contaminants cover the upper surface of the filtration material, the water permeability of the filtration material deteriorates in a short time.

[0007] In the forced filtration type, polluted water is forcibly taken in rather than natural running water and the filtration material is permeated and filtered to cause clogging in the filtration material, resulting in poor water permeability.

Therefore, both the open osmosis filtration type and the forced filtration type have a problem that the water permeability is deteriorated and the filtration ability is inevitably lowered. In the forced filtration type,
Since the polluted water is forcibly taken in, there is a problem that clogging of the filtration material is persistent and cannot be easily regenerated.

The multi-tank type has the problems that the apparatus is large and complicated and that cleaning is time-consuming.

It is an object of the present invention to provide a polluted water filter device which is a small and simple device, is less likely to cause clogging, and is easy to wash.

Therefore, the present invention is

A filter material is provided between the intake port and the drain port inside the main body, which is hollow and has an intake port provided in the middle part and a drain port provided in the upper part and a pollutant discharge port provided in the lower part. Water filtration device characterized by making the space of the room a pollutant sedimentation chamber

The above-mentioned problems can be solved by providing

[0013]

[Operation] The filtered water that passes through the intake is taken in. The filtered water taken in deposits relatively heavy pollutants in the pollutant settling chamber in the main body. The filtered water that has been precipitated passes through the filtering material. The relatively light weight contaminants that did not settle by passing through the filter material are filtered by the filter material and discharged from the drainage port.
