Description

[Detailed description of the device]

INDUSTRIAL APPLICABILITY The present invention is used in a washing machine or the like for washing or laundering various articles, and can easily replace a filter part for filtering dirty water and dispose of a used filter part. Regarding tubular filters that can be used.

[Prior Art] A conventional tubular filter used for treating wastewater of a washing machine or the like has a belt-like circular shape on the outer side or the inner side as illustrated in FIG. 4 by referring to Japanese Utility Model Publication No. 1-16490. A filter material 14 for removing dust and the like retained by the shape-retaining belt 21, a porous protective cylinder 15 for supporting the filter material 14 from inside, and a discharge tube 16 for the washed solution, and the above-mentioned protection. The net bag-like adsorbent 17 between the pipe 15 and the discharge pipe 16 and the ends of the protective pipe 15 and the discharge pipe 16 are supported, and the openings of both ends of the filter material 14 and the adsorbent 17 are closed. A ring-shaped end plate 18 and a ring-shaped end plate 18 sandwiching the filter material 14 are stretched around the ring-shaped end plates 18 to tighten them. It is composed of a plurality of annular packings 20. Therefore, all of these components are constructed in a disassembled and assembled manner, and when assembled, all the components are tightened by the elastic force of the expandable fixing rod 19.

[Problems to be solved by the invention] A cylindrical filter such as a cleaning machine passes sewage from the outer peripheral side to the inner side and filters it. Therefore, the higher the filtering capacity of the filtering material, the higher the water pressure. Since it needs to be raised, high water pressure is applied to the outer filtration material. The conventional tubular filter for sewage treatment is constructed so that all parts can be disassembled and assembled, and is supported by a fixed rod that can expand and contract when in use.Therefore, when the tubular filter is deformed by water pressure, the fixed rod expands and contracts. The length may change and unfiltered sewage may enter the interior. Therefore, it is required to increase the elasticity of the fixed rod, but the stronger the expansion and contraction elasticity, the more difficult it is to hang and remove the work, and in practice the usage is restricted depending on the filter material. It will be.

Unlike the domestic sewage, the sewage of a washing machine contains a lot of cleaning chemicals, dust, and pollutants. Therefore, when replacing the tubular filter, the tubular filter must be replaced. Since these pollutants and polluted solutions are remarkably attached, the human body becomes dirty and extremely unsanitary. In the conventional tubular filter, when removing the tubular filter part, the expandable fixing rod is removed and all the components are disassembled. Therefore, when removing the fixing rod, the tubular filter part is of course pulled out. In some cases, it will come into contact with a highly contaminated tubular filter, and in the assembly after replacing the tubular filter, the work of interposing annular packings at the contact points of all parts to which contaminants are attached is necessary. Therefore, the replacement work of the tubular filter portion was unsanitary and inefficient.

[Means for Solving the Problems] In order to solve the problems of the prior art, the present invention is composed of a paper filter, and a shape-retaining tape is adhered to retain the outer shape, and the upper and lower ends are incinerated. A cylindrical filter, which is made by adhering circular ring packing made of an easy material and is integrated, a perforated outer cylinder to which this cylindrical filter is fitted and a cloth bag filled with adsorbed deodorant, are concentrically spaced. The multi-inner cylinder is installed on the annular plate and integrated, and the annular fixing screw is screwed onto the multi-inner cylinder to open the openings of the cylindrical filter, multi-outer cylinder and multi-inner cylinder. Since the structure is such that the annular lid covering the ends is tightened, all the components are put together in the minimum number of components, and it is easy to replace the cylindrical filter.

That is, when replacing the cylindrical filter and the cloth bag-containing adsorption deodorant, it can be taken out by a simple operation of removing the annular fixing screw and removing the annular lid, and after replacing, the annular lid is removed. Since it is only the operation of covering the body with the annular fixing screw and tightening it, the replacement can be efficiently performed without polluting the human body.

[Action]

 The tubular filter 6 according to the present invention accommodates the adsorbing deodorant 10 contained in a cloth bag in the space between the perforated outer cylinder 2 and the perforated inner cylinder 3, and after the cylindrical filter 6 is fitted onto the perforated outer cylinder 2, The open ends of the filter 6, the porous outer cylinder 2 and the porous inner cylinder 3 are covered with an annular lid 11, and the distal end side of the annular fixing screw 13 is passed through the center hole 12 of the annular lid 11 so that the distal end of the porous inner cylinder 3 is covered. It is a structure that is assembled by being screwed onto the part.

Therefore, since it is constituted by the minimum number of constituent parts, when replacing the cylindrical filter 6, it is only necessary to remove the annular fixing screw 13 and remove the annular lid 11. The adsorbing deodorant 10 can be easily removed, and after the replacement, the replacement is completed only by fitting the annular lid 11 and tightening the annular fixing screw 13. In this case, by making it easier to rotate the ring-shaped fixing screw 13, the removal and tightening operations become easier.

Since the cylindrical filter 6 is shaped by the annular felt 8 adhered to both end surfaces and is shaped by the inexpensive shape-preserving tape 9 wound around the outer periphery by the adhesive, a dedicated band-shaped circular shape protector is used. The band is no longer necessary, and the annular felt 8 comes into contact with the annular lid 11 and the annular plate 4 after assembly and acts as a packing material.

The present invention has the above-mentioned effects in the configuration, and when assembled into a sewage treatment tubular filter, sewage passing from the outside to the inside is dusted by the outer cylindrical filter 6 and hair. The substances contained in are removed, and the adsorbed deodorant 10 on the inside filters and deodorizes the polluted substances. In this case, since the annular plate 4 and the annular lid 11 at both ends are fixed by the annular fixing screw 13 via the porous inner cylinder 3, and the cylindrical filter 6 is tightened from above and below via the annular ring 8, the hydraulic pressure is reduced. Even if it is deformed, unfiltered sewage will not leak inside.

[Embodiment] An embodiment of the present invention shown in FIG. 1 will be described. On the annular plate 4, one end side of the perforated outer cylinder 2 and the perforated inner cylinder 3 having the threaded portion 5 on the outer circumference of the other end is installed concentrically with a gap therebetween to form the filter mounting portion 1. On the other hand, the bent paper 7 is formed into a cylindrical shape, and an annular felt 8 which also serves as a packing is adhered to both opening surfaces of the paper to retain the shape, and a plurality of shape-retaining tapes 9 are attached to the outer periphery of the paper 7. A cylindrical filter 6 is formed by being wound with an adhesive and fitted onto the porous outer cylinder 2. An adsorbing deodorant 10 in a cloth bag that fits in the gap between the porous outer cylinder 2 and the porous inner cylinder 3, and an annular lid 11 that covers the open ends of the cylindrical filter 6, the porous outer cylinder 2 and the porous inner cylinder 3. An annular fixing screw 13 is formed which penetrates the center hole 12 of the annular lid 11 and is screwed to the other end of the perforated inner cylinder 3 to tighten the annular lid 11.

Therefore, the present invention comprises the filter mounting portion 1, the cylindrical filter 6, the absorbent odorant 10 with cloth, the annular lid 11, and the annular fixing screw 13, which is the minimum in disassembly and assembly. It is composed of 5 parts, and when these 5 parts are assembled, a sewage treatment cylindrical filter as shown in FIGS. 2 and 3 is obtained.

[Effects of the Invention] The present invention is composed of a minimum number of constituent parts, and by removing the annular fixing screw and the annular lid, both the cylindrical filter and the adsorbing deodorant can be easily replaced. In this case, the filter mounting part is not disassembled, so the assembly after replacement becomes simple and hygienic, which is extremely effective in practice. In addition, the cylindrical filter to be discarded after it is used is composed of paper, felt and tape that are inexpensive and can be incinerated without pollution, which not only reduces the consumption cost but also disposes of the dirty used cylindrical filter. The treatment becomes easier and it can contribute to environmental purification.
