Abstract

<P>PROBLEM TO BE SOLVED: To provide a filter designed to hardly clog a filtration tank through removing organic matter deposited onto a filtering material in the tank and organic matter sucked onto the tank out of the tank. <P>SOLUTION: The filter is configured such that: by setting wood stones 2 at the bottom of a filtering material 3 spread all over a sloping columnar filtration tank 1, microbubbles released from the wood stones 2 remove organic matter deposited onto the filtering material 3; the organic matter thus removed from the filtering material 3 and organic matter sucked into the columnar filtration tank 1 are made to float at the upper part of the sloping columnar filtration tank 1 by aeration; the organic matter thus made to float is adsorbed to the interface of the microbubbles; a pipe 4 projects from the surface 5 of water to discharge the resultant microbubbles via the pipe 4; and a sloping columnar organic matter-retrieving container 6 is attached to the exit of the pipe 4 for retrieving the resultant microbubbles discharged via the pipe 4. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention aims to remove the organic matter adhering to the filter medium laid in the filtration tank and the organic matter sucked into the filtration tank to the outside of the filtration tank to make the filtration tank difficult to clog. The present invention relates to a filter device for preventing clogging.

  If the filter medium in the filtration tank becomes dirty or organic matter accumulates in the filtration tank, the filtration tank is clogged.

  Provided is a filtration device that removes organic matter adhering to a filter medium in a filtration tank and organic matter sucked into the filtration tank to the outside of the filtration tank so that the filtration tank is not easily clogged.

  In order to solve the above-mentioned problems, the present invention is configured so that the shape of the filtration tank is a Nade type cylindrical filtration tank so that the bubbles are bubbled in the upper part of the filtration tank, and the bubbles flow in the upper part of the Nade type cylindrical filtration tank In order to remove the organic matter adhering to the filter medium by installing a Nade type cylindrical filter tank in the water and aeration of the entire filter medium, a wood stone is installed at the bottom of the filter medium, and the organic substance removed from the filter medium and the filter tank The aspirated organic matter floats to the top of the Nade shaped cylindrical filtration tank by aeration, the organic matter floated on the top of the Nade shaped cylindrical filtration tank is adsorbed to the interface of the foam, and a pipe is attached to the top of the Nade shaped cylindrical filtration tank. The pipe protrudes from the water surface to discharge the organic substance adsorbing foam from the pipe, and a Nade shaped cylindrical organic substance recovery container is attached to the outlet of the pipe to recover the organic substance adsorbing foam discharged from the pipe. An air discharge port is made at the bottom of the Nde-shaped cylindrical organic matter collection container to discharge the air inside the De-shaped cylindrical organic matter collection container, and a small filter is installed at the air discharge port to prevent the organic substance adsorption bubbles from being ejected from the air discharge port. In order to allow seawater to circulate in the filtration tank, a plurality of water inlets are formed around the upper side surface of the Nade type cylindrical filtration tank, and a drain port is formed on the bottom side surface of the Nade type cylindrical filtration tank. Attach a drainage water pump to the mouth and clog the filter between the drainage port and the woodstone to prevent the drainage water pump from sucking bubbles.

  By installing a wood stone at the bottom of the filter medium laid in the filter tank and aeration of the entire filter medium, organic substances adhering to the filter medium were removed and aerobic bacteria living in the filter medium were activated and removed from the filter medium. By removing the organic matter and the organic matter sucked into the filtration tank into the organic matter recovery container, it becomes difficult for the organic matter to be accumulated in the filtration tank, so that the filtration tank is less likely to be clogged.

An embodiment of the present invention is shown in FIG.
A Nade type cylindrical filtration tank 1 is installed in the water, Woodstone 2 is installed at the bottom of the Nade type cylindrical filtration tank 1, a filter medium 3 is laid on top of the Woodstone 2, and a pipe is placed on the top of the Nade type cylindrical filtration tank 1. 4, the pipe 4 protrudes from the water surface 5, a nade-shaped cylindrical organic matter recovery container 6 is attached to the outlet of the pipe 4, an air outlet is formed at the bottom of the nade-shaped cylindrical organic matter recovery container 6, and a small filter 7 is provided at the air outlet The tube 8 is connected to the woodstone 2, the air pump 9 is connected to the other port of the tube 8, the drainage port 10 is formed on the lower side surface of the nade type cylindrical filter tank 1, and the nade type column filter tank 1 A plurality of water inlets 11 are formed around the upper side surface of the basin, a water pump 12 for drainage is attached to the drain port 10, and a filter 13 is packed between the drain port 10 and the woodstone 2.

"Other embodiments"
In the embodiment of FIG. 1, the shape of the filtration tank and the organic matter recovery container is a Nade type cylindrical container, but in other embodiments, a funnel-shaped polygonal container may be used. In the embodiment of FIG. 1, aeration is generated by woodstone, but airstone may be used in other embodiments.

It is the top view which showed embodiment of the clogging prevention filtration apparatus for saltwater fish breeding.
