【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 1 is a top view showing an embodiment of the filter body of the present invention, FIG. 2 is an operation explanatory view of the filter body of the same embodiment, and FIG. 3 is an embodiment of the filter device of the present invention. FIG. 4 is a perspective view showing an example, and FIG. 4 is an installation explanatory view of a filtering device in the same embodiment. 1 to 4, parts that are the same as or correspond to those of FIG. 5 showing a conventional example are assigned the same reference numerals and explanations thereof will be omitted.

The filter body 30 is formed into a flat bag-like shape by stacking same-shaped cloths on each other and sewing them together as shown by a broken line, and each chamber described later is formed separately. The cloth is preferably cotton, for example, because of its excellent filtering ability. Further, the filter body 30 can be configured in any shape according to the shape of the water surface of the water tank.

The filter body 30 is provided with an inflow port 31 for introducing water to be filtered, and a water diversion chamber 32 communicating with the inflow port 31 is formed. A plurality of filtration chambers 33, one end of which communicates with the water diversion chamber 32 and the other end of which is closed, are arranged in parallel. Each water diversion chamber 32 forms a substantially rectangular envelope-shaped space, and can be expanded into a cylindrical shape by being filled with water.

A storage chamber 34 that forms a rod-shaped space is provided along the three sides of the side edge of the filter body 30. An opening 34a is provided in at least one end of each storage chamber 34.

FIG. 2 is an explanatory diagram showing a completed state of the filter body 30. In the water diversion chamber 32 of the filter body 30, a filter material 35 made of, for example, soft wool, felt, or sponge is housed and held so as to be located between the inflow port 31 and the openings of the respective filtration chambers 33. .

On the other hand, a levitation body 36 (shown by hatching in FIG. 2) is inserted into each storage chamber 34 of the filter body 30 from each opening 34 a and is stored and held. The levitation body 36 is mounted to levitate the filtration body 30, and is composed of, for example, a rod-shaped body formed of a substance having a specific gravity lower than that of water, or a hollow tubular body having both ends sealed. can do.

A connection pipe 41 that constitutes a relay pipe 40 that guides water discharged from a pump described later is inserted into the inflow port 31 of the filter body 30. The connecting pipe 41 is formed with a bulging step portion 41a which can be fitted into the inflow port 31 and has a diameter larger than that of the inflow port 31. That is, the bulging step portion 41a, when fitted to the inflow port 31, serves as an anti-drop function that prevents the bulging step part 41a from falling off from the inflow port 31 due to the force of the discharged water.

FIG. 3 is a perspective view showing an embodiment of the filtering device 60 of the present invention. The filtering device 60 includes a filter body 30, a relay pipe 40, and a pump 50. The pump 50 includes a water intake port 51 for taking in water, and a water discharge pipe 52 for discharging water. A net 51a is attached to the water inlet 51 to prevent inhalation of breeding organisms such as fish and relatively large dust. Reference numeral 53 is a power cord for supplying power to the pump 50. The relay pipe line 40 is composed of the connection pipe 41, a water discharge pipe 52 of the pump 50, and a detachably provided relay pipe 42 connecting the both.

FIG. 4 is an explanatory view showing the installation state of the filtration device 60. The pump 50 is installed on the bottom surface of the water tank 10, and the filter body 30 formed in a flat bag shape is floated on the water surface by the action of the float body 36. Therefore, even if the area of the filter body 30 is slightly increased, it does not occupy the migration space or breeding space for fish or the like.

On the other hand, the pump 50 and the filter body 30 are connected by a relay conduit 40. Here, when the pump 50 starts the pumping operation, the water W in the lower part of the water tank 10 is absorbed toward the water inlet 51 of the pump 50 as shown by the arrow, and passes through the relay pipe 40 to the inside of the filter body 30. Is supplied to.

As shown in FIG. 2, the water supplied from the connecting pipe 41 is primarily filtered by passing through the filter medium 35 held in the water diversion chamber 32. Here, since the plurality of filtration chambers 33 are arranged in parallel along the advancing direction of the filtered water, the filtered water that has passed through the filter material 35 is dispersed in each of the filtering chambers 33 as shown by the arrow. Supplied.

As shown in FIG. 3, each of the filtration chambers 33 is filled with the filtered water that is forced to flow by the pump 50 and expands into a substantially cylindrical shape. The filtered water that fills the inside of each water diversion chamber 32 permeates outward from the wall formed by the cloth of each filtration chamber 33 as indicated by the arrow, and is secondarily filtered. That is, the water W is filtered in two stages by the filter medium 35 and each filter chamber 33. Therefore, it is preferable that the effective flow path diameter at the time of filtering is smaller than that of the cloth forming the wall of each filtration chamber 33 than that of the filter medium 35.

As shown by the arrow in FIG. 2, the filtered water is evenly dispersed and flows down into the water tank 10 from the entire area of the walls of the respective filtration chambers 33 constituting the filter body 30. In this way, as long as the pump 50 is performing the pumping operation, the water in the water tank 10 is circulated and filtered by the filter medium 35 of the filter body 30 and the filter chambers 33.

As described above, the filter body 30 has a flat bag-like shape and floats on the water surface. Therefore, even if the filter body 30 is large, that is, the filtration area is wide and a large filtration capacity is secured, the breeding space is maintained. Never occupy. Further, if the filter body 30 has a large filtration capacity, the frequency of clogging of each filter chamber 33 is low, so that the filter body 30 does not need to be frequently washed, and management is easy.

It should be noted that in the filter body 30, the filter chamber 33 may be divided into a plurality without being divided into a plurality, but in that case, the drainage is the end portion in the traveling direction (the closed end of the filter chamber 33). Portion), the filtering action may be concentrated only in the vicinity of the closed end portion. Considering these things, it is preferable to provide a plurality of filtration chambers 33.

By the way, the length of the relay pipe 40 connecting the pump 50 and the filter body 30 needs to be adjusted according to the water depth of the water tank 10. The length of the relay pipe 40 may be adjusted by cutting the relay pipe 42 according to the water depth, or a plurality of relay pipes 42 having different lengths may be prepared in advance and selected from them. You may do it. Further, the relay conduit 40 is configured by using at least a part thereof a flexible member that can bend and stretch, and the pump 50 and the filter body 30 can be connected to each other when the water depth of the water tank becomes maximum. If the length of the relay conduit 40 is set in this way, it is not necessary to adjust the length of the relay conduit 40 according to the change in water depth. In this case, for example, the relay pipe 42 may be made of a highly flexible material such as a rubber pipe or a vinyl pipe. In this embodiment, the connection pipe 41 and the relay pipe 42 are formed separately, but they may be formed integrally.

The filter material 35 of the filter body 30 and the cloth forming the filter chambers 33 exhibit a so-called closed filtration mode as dirt is captured, and the filtering function is not improved over time. As is well known. In addition, the cloth forming the filter medium 35 and each of the filtration chambers 33 is not limited to merely performing physical filtration, but is also a biological material that can be treated by adsorbing and decomposing dirt by forming a biofilm such as bacteria. The simple filtration is the same as the conventional filtration device. Therefore, by adhering bacteria to the filter material 35 in advance, the filtration performance of the filter body 30 can be further improved.

The filter material 35 can be omitted depending on the necessity of the filtering ability. Further, the inflow port 31, the water diversion chamber 32, the filtration chamber 33, the storage chamber 34, etc. formed in the filter body 30 may be formed separately by sewn as in the present embodiment, or separated by adhesion. You can also The pump 50 is not limited to the one installed in water shown in this embodiment, and it goes without saying that the pump 50 may be installed outside the water tank.

As described above, according to the filter body and the filter device of the present embodiment, since the filter body has a flat bag shape and floats on the water surface, the filtration area is widened to secure a large filtration capacity. be able to. Therefore, it is not necessary to wash the filter body frequently, and it does not occupy a breeding space for fish or the like and can be made compact. Further, since the filter body is a cloth, it is easy to care for cleaning and the like, and the storage space can be reduced by folding.

[0034]

[Effect of device]

 As described above in detail, since the filter body of the present invention has a flat bag shape and floats on the water surface, it occupies a breeding space for fish etc. even if the filter area is wide and a large filter capacity is secured. Never. By ensuring a large filtration capacity, it is possible to reduce the frequency of washing, so management is easy. Further, since the filter body is made of cloth, there are advantages that the material cost is low, maintenance such as washing is easy, and the storage space is small by folding.

When the filter medium is housed in the water diversion chamber of the filter body, the filtration ability is further improved because the filter medium and the cloth forming the filter chamber of the filter body are filtered in two stages. Furthermore, it is possible to accelerate the biological filtration process by attaching bacteria to the filter medium.

When the opening for inserting the levitation body is provided in the storage chamber of the filtration body, the work of attaching the levitation body to the filtration body is facilitated and the manufacturing cost is reduced.

Further, since the filter device of the present invention has the filter body, a pump for pumping water, and a relay pipe line for guiding the water from the pump to the filter body, it is floated on the water surface. Circulating filtration can be performed by supplying water to the filter.

When a bulging step is provided at the discharge side end of the relay pipe, the bulging step fits into the inlet of the filter, so that the filter falls out of the relay pipe. Can be prevented.
