から濾過処理された清澄な液体が得られることとなる。(Function) In the filtration device having the above-mentioned former configuration, among the liquid to be filtered supplied into the storage tank 1, impurities larger than the minute gap 9 between the filtration materials 717a pass through the minute gap 9. Instead, only the clear liquid passes through the minute gap 9 and is then discharged to the outside of the water-permeable side wall 6, resulting in a filtered clear liquid.

のとなる。Thus, the small-diameter filter medium 7a has a portion protruding from the inner peripheral surface of the large-diameter filter medium 7 that rotates in the filter medium pressing means 1.
4 in the radially outward direction, even if solid matter adheres to the small-diameter filter medium Ia, the solid matter will be removed from the other large diameter when the filter medium 7a moves radially outward. It will be rubbed off toward the hollow part 13 side by the filter material 7 of the diameter, and it will be difficult to get caught between the surface filter materials 7 and 73.

９に目詰まりを生じないものとなるのである。Furthermore, even if solid matter is caught in the minute gap 9 between the refiltration materials 7 and 7a, the solid matter will be crushed by the surface filtration materials 7 and 7a and pass through the minute gap 9 in a minute state. Otherwise, it is rubbed off toward the hollow portion 13, and the minute gap 9 is not clogged.

ある。On the other hand, in the latter dehydration filtration device, even if the object to be filtered is sludge or the like with a small water content, the substance is compressed by the screw 14a and formed by the filter medium 7b in the filtration tank 1a. It can be transferred within the hollow part 13a. Here, moisture is released from the substance to be dehydrated by compression and transfer by the screw 14a, but the moisture passes through the minute gaps 9a between the filtering materials 7b and is drained outside in a filtered state. The solids that do not pass through the minute gap 9 are discharged from the outlet 21 of the filter tank 1a in a dehydrated state.

It is. One of the filtering media 7, 7a of the pair of filtering media 7, 7a is formed so that its outer diameter D2 is approximately the same as the inner diameter of the filter tank 1. Moreover, the other filter medium 7a has an inner diameter Da,
It is formed in the shape of a hollow disk whose outer diameter Da2 is smaller than the diameter D1102 of one filter medium 7, and its width La is the same as the width of one filter medium 7. These plurality of filter media 7, 7a of different diameters can be mutually slidably contacted between collar-shaped support plates 8, 83 protruding from upper and lower appropriate positions in the filtration tank 1 in a state in which the filter media 7, 7a are stacked alternately in different sizes. The water-permeable side wall portion 6 is provided inside the water-permeable side wall portion 6. Reference numeral 9 denotes a minute gap formed between each filter medium 7, 7a as shown in FIG.

The filter medium 7 is attached to a crankshaft 16 that is rotated by a motor 15 with a speed reducer mounted on the upper part of the filter medium 7, and is set to perform circular motion along the inner circumferential surface of one large diameter filter medium 7. Further, the pressing roller 14 can idle relative to the crankshaft 16.

本実施例は以上の構成からなり、次にその使用例並びに
作用について説明する。The present embodiment has the above configuration, and next, an example of its use and operation will be explained.
先ず、供給口２から濾過槽１内に汚水が供給された場合

下方の貯留槽５内に沈降する。First, when waste water is supplied into the filter tank 1 from the supply port 2, a plurality of filter materials 7, 7a are stacked on top of each other inside the water-permeable side wall 6 of the filter tank 1. Because of this presence, the waste water does not pass through the side wall portion 6 as it is. Substances (clear water) smaller than the minute gaps 9 between the filter media 7.7a are filtered through the filter media 7.7a. Solid substances that are larger than the minute gap 9 do not pass between the filter media 7 and 73, and are discharged to the outside of the side wall portion 6 after passing through the space between Ia.
It settles into the storage tank 5 below.

と摺接することとなる。Next, in the above state, the motor 15 is operated to cause the suppressing roller 14 to perform a circular motion along the inner circumferential surface of the large-diameter filter medium 7 by the action of the crankshaft 16. One large-diameter filter material 7 has approximately the same dimensions as the inner diameter of the storage tank 1, so it does not move radially outward, but the inner circumferential surface of the other small-diameter filter material 7a Since the small-diameter filter medium 7a is partially protruded inward from the inner circumferential surface of the filter medium 7a, the inner circumferential surface of the small-diameter filter medium 7a is pressed by the pressing roller 14. the result,
As shown in FIGS. 3 and 4, the small-diameter filter material 7a is sequentially pressed outward in the radial direction and slides against the large-diameter filter material 7. Furthermore, although the refiltering media 7 and 7a have different outer diameters and inner diameters, their width and La are the same, so the smaller diameter filtering material 7a is in sliding contact with the entire surface of the larger diameter filtering material 7. Become.

The filtering material 7a then moves in the direction of arrow B and reaches the state shown in FIG. This means that it is removed by being pressed by the user, making it difficult for undue biting to occur.

りが生じ難いものとなった。(Effect of the invention) As shown in the above, in the sewage filtration device according to the present invention, filtering materials of different sizes and diameters are stacked one on top of the other, and the object to be filtered passes through the minute gaps formed between the filtering materials. In addition, the small-diameter filter material protruding inward from the inner peripheral surface of the large-diameter filter material is pressed by the pressing means, and the small-diameter filter material is pushed outward in the radial direction. Since the structure is configured so that the solids are pressed sequentially in one direction, when solids larger than the small gap between the filter media adhere to the surface of the small diameter filter, they are scraped off to the hollow side by the other large diameter filter. So,
It is difficult for solids to get caught between the refiltration materials, and even if solids do get caught between the refiltration materials, the solids will be crushed by both filtration materials and will pass through the minute gap, or will be trapped in the hollow part. In any case, it was rubbed off to the side, and in any case, it became difficult for clogging to occur in minute gaps.

処理が行えるという格別な効果を有するに至った。As a result, even when filtering heavily contaminated sewage, there is no need to replace clogged filter media in a short period of time, which is the case with conventional filtration devices, and the filter can be filtered for a long period of time. This has resulted in the exceptional effect of being able to perform highly efficient filtration processing without replacing the material.

It goes without saying that filtration can be performed through the small gaps between the materials, and dehydration of the object to be filtered can be carried out, but the tapered portions provided on the inner peripheral surface of each filter material and the screw blades come into contact with each other, allowing them to slide against each other. Similarly to the above, it was possible to prevent solid matter from clogging between the filter media. As a result, the water emitted from the object to be filtered is not unduly retained in the filtration tank, and the wastewater removal process can be performed appropriately, resulting in a biased effect that the dehydration filtration efficiency can be made very good. There is.
