Description

The present invention relates to a drain sludge removal device as described and claimed herein. With this drainage sludge disposal device of the invention a sludge prevention / disposal is used (described in European patent application EP-A-1676478, which is divisive of the present application) which is installed in a place where the one that metabolites of various germs, molds and the like cause mud and bad odors, such as drainage outlets from kitchen sinks, bathrooms and toilet floors, and which is useful for removing mud, to prevent the appearance of mud or To control it. The present invention also relates to a sludge removal device comprising a container therefor, and to a sludge removal process therewith. The invention relates, in particular, to a sludge disposal device for a waste basket in a kitchen sink, of a type in which the drain outlet of a domestic kitchen sink is made wider than the waste pipe. main drain, a waste basket is installed that collects the waste that comes out along with the drain material, such as kitchen material waste, and the disposal device is disposed of when a certain amount of waste accumulates.

It is known that the main component of the sludge in the drain outlets of kitchen sinks and bathrooms are polysaccharides secreted by bacteria, when they use food materials, surfactants, soaps, human dirt and other sources of nutrients.

So far, it is well known, as sludge prevention chemicals for waste baskets installed in the drain outlets of domestic kitchen sinks, store in plastic networks

or containers in the form of a compressed basket, of which a chlorine-type oxidizing agent, such as trichloroisocyanuric acid, dichloroisocyanuric acid or bromochlorodimethylhydantoin, alone or mixed with other components, is molded under pressure and hung on chains or similar in waste baskets to prevent the appearance of mud in the baskets (Japanese patent open to the public No. Hei 8-128090). These chemicals have been marketed under trademarks, such as "Slime Removing Agent," for practical use in recent years.

Among the chemicals mentioned above, the bleaching powder type mud removal agents show effects in the prevention of sludge and bad odors from waste baskets, thanks to the high sterilization power of the active component of a hypochlorite oxidizing agent, and by Both are widely used. Due to their high oxidation power, waste baskets and drainage pipe materials around them deteriorate or corrode, and poisonous chlorine gas is also generated. An amount of chlorine gas generated increases particularly when the agent reacts with an acidic substance, such as vinegar, causing a dangerous situation. Chemicals of the isocyanuric acid type containing trichloroisocyanuric acid or the like as an active component present safety problems so that their contact with sodium hypochlorite or alkaline detergents generates gas with irritating odors, such as explosive nitrogen trichloride.

To solve the above problems, a variety of "sludge removal agents" using germicides other than chlorine-type oxidizing agents have been proposed. For example, those known are peroxides, such as sodium percarbonates, potassium persulfate and sodium perborate (Japanese patents open to the public No. Hei 8-268818 and No. 9-31495), iodine-type germicides such as povidone iodine (Japanese patents open to the public No. Hei 9-124423 and No. 9-227317), chemical products that are composed of sulfur compounds, such as sulfite, and chemical products for pasteurization (Japanese patent publication open to the public No. Hei 9-124422), agents Volatile pasteurization agents such as ortho-phenylphenol, diphenyl, 2-isopropyl-5-methylphenol and hinoquitiol (Japanese Patent Publication Publication No. Hei 9-206040), inorganic germicides whose silver ions, copper ions or the like are supplied by inorganic compounds such as zeolite or silica gel (Japanese patent applications open to the public No. Hei 8-157305.9-30915 and No. 9-194313), and germicidal tablets are molded under pressure industrial or the like, such as para-chlorometaxylenol, alone or with suitable dissolution regulators added.

These “sludge removal agents” that use germicides other than chlorine-type oxidizing agents are stored in plastic nets or basket-shaped containers and hung by chains or other means in the waste baskets, similar to the “agents of waste sludge removal ”which is composed of chlorine-like oxidizing agents. Some of the above agents are marketed as "sludge removal agents" that do not use chlorine-like oxidizing agents. These have a weaker sterilization power than the known "mud removal agents" containing chlorine-like oxidizing agents as the active components and insufficient preventive effects for mud and odors so that it is not yet popularized.

Japanese Patent Publication Publication No. Hei 7-184823 has disclosed "mud removal agents" in which an antimicrobial agent, such as a mixture of 5-chloro-2-methyl-4-isothiazolin-3- one and 2-methyl-4-isothiazolin-3-one, is supported by porous fine inorganic particles, such as hollow porous silica, and is stored in a water permeable bag, for example, composed of nonwoven textile material, or supported by a Water soluble substance, such as a protein or polysaccharide, and is manufactured as a film. 5-Chloro-2-methyl-4-isothiazolin3-one has a strong antimicrobial potency and does not corrode materials or generate gas. However, it is easily soluble in water, so that it suffers from the inconvenience of a shorter shelf life than known chemicals. In addition, there is a safety problem when used in homes due to severe skin irritation.

In addition to those mentioned above, devices are known that have fixing sections for fixing containers that store sludge removal agents to waste basket handles through the joints (Japanese Patent Publication Publication No. Hei 9-292), types using mesh baskets for fluororesin-coated waste (Japanese patent publication open to the public No. Hei 8-158441), electrolytic, acidic, ionic water jet launching devices from circular tubes fixed around the mesh baskets (no. Japanese publication of utility model registration Hei 6-46069), and germ and mold preventive devices that provide solutions that have a germ and mold prevention action on the upper parts of the inlet tubes (Japanese open patent publication to the public No. Hei 9-154923).

The sludge prevention / disposal agents for use with the drain sludge disposal device of the present invention are described in European patent application EP-A-1676478, which is divisive of the present application.

The drain sludge removal device of the present invention comprises a rubber or plastic filter and a container for the storage of solids containing a substance that retards the growth of microorganisms that can be installed in the lower part of said rubber filter or plastic and that presents a way to allow its installation on top or above an inlet pipe. The rubber or plastic filter has rectangular drain inlet holes provided on the inner peripheral edge of the filter and has solution outlet holes provided on the inner side of the filter, and can spread the solution of dissolved solid on the surfaces of walls contaminated with mud. The container has an annular shape and comprises a lid and a main body. The drain inlets of the rubber or plastic filter in places in fluidic communication with the drain inlet holes were provided in the container.

In order to spread a solution of dissolved solid on the surfaces of mud-contaminated walls, circular holes of solution outlet are provided on the inner face of the main body of the container.

A solid, if it is small granules, can be placed inside the drain inlet holes. When a solid is stored in a container, a container can be used that has a structure that can be divided into two parts and combined with known joint materials, or that has an opening to put solids and a filter part of the container inside. It is possible to install the container on top or above an inlet tube. If there is a plug or a filter in an inlet pipe or a waste basket, a container similar to the plug or filter can preferably be used. Examples of filter shapes include a variety of commercially available filters attached to the drain outlets of kitchens, bathrooms and others, such as radially cut rubber filters, plastic filters with waste inlet openings in the center of the filter. , filters with slit-type waste collectors that can be opened and closed, and small plate-shaped filters that have metal nets or small holes to prevent debris from entering and allow only one drain inlet. A container can be installed in a simple way, as such, if it is a filter to be fixed at the drain outlet of a kitchen sink.

Various known materials, such as plastics, rubber and metal, can be used for the containers. A variety of plastics is preferably used from the point of view of cost, processing and other conditions. In the case where a container consists of a filter to be fixed in a drain outlet of a kitchen sink, a plastic filter, for example, a colored plastic filter, can be used instead of conventional rubber filters .

The drain inlet holes extend from the top surface to the top of the surface facing into the container. By providing said drain inlet holes, an inlet amount is controlled to prevent a solution of dissolved solid from flowing back through the drain inlet holes, even if the water is in large quantity.

Solution outlet holes are provided on the inner face of the container so that a solution of dissolved solid can be spread on the surfaces of mud-contaminated walls. Solution outlet holes are also provided on the inner side of the peripheral edge of the filter, such as a radially cut rubber filter, to diffuse the solution on the front and rear surfaces of the rubber filter.

Circular holes of solution outlet are provided in the lower part of the container and the inner and outer faces so that a solution can be diffused over the surrounding area of an inlet pipe, a waste basket and the front and rear surfaces of a rubber filter

The drain inlet holes in the container are configured as grooves, which are effective in preventing waste from entering. In this case, the slit width is adjusted in an interval so that only a small amount of waste is entered and the water entering is not blocked due to surface tension. It is possible to cover the openings with a material that allows water to pass through it, such as non-woven textile material, if it allows drainage to enter. In this case, the total opening area of the drain inlet holes is considered to be an opening area for an equivalent amount of water flowing through it.

The way that guides the drain water into the container smoothly and prevents waste from entering the container refers to slit-shaped drain holes. It is characterized in that the drain inlet slits extend from the upper surface of the container to the top of the surface facing into the container, and have more than one drain inlet groove consisting of one or more grooves along from the direction towards the center of the inlet tube at appropriate intervals. The grooves are 0.5 to 4 mm, additionally 0.5 to 3 mm, and particularly 1 to 2 mm wide. The slits of 0.5 mm or wider may allow water to enter the vessel, since the balance of the surface tension of the water, which differs from the circular holes, is broken. The entry of waste can be avoided as far as possible if the grooves are 4 mm or narrower, preferably 3 mm or narrower.

If grooves are provided along the direction toward the center of the inlet tube from the periphery when the drain enters the inlet tube, even narrow grooves may allow the drain to enter the container. The grooves extend from the top surface of the container to the top of the surface facing into the container. The length of the slits is longer than the width, and is selected arbitrarily. It is preferable that it is 2 mm or longer, preferably 5 mm or longer, in the total length of the upper and lateral parts. The grooves can also extend towards the lower side or the lower part of the container, also being used as solution outlet holes.

Materials used for containers with inlet holes can be made so that they are

hydrophilic by the use of hydrophilic plastic materials for the containers, using materials with hydrophilic surfactants kneaded inside the plastics of the container, or by applying hydrophilic paints or coating agents on the surface of the containers. Next, the influence of surface tension of water becomes small. Therefore, it is possible to let the water flow from the inlet drainage holes of the container into the container more smoothly and also prevent the oils contained in the drain from adhering to the container.

It is possible to make a drain inlet holes of the container which, if they are composed of hydrophilic non-woven textile material, allow only water to infiltrate into the textile material and flow into the container to dissolve a chemical without waste entering the same. For this, the size of the inlet holes can be selected arbitrarily considering infiltration through the nonwoven textile material.

In the present invention, a wall surface contaminated with mud refers to an extension that has an area, such as a flat or curved surface, on which mud is generated, such as the surface of the internal wall of the drainage pipes of kitchen sinks, bathrooms and toilet floors, the front and rear surfaces of rubber filters at the drain outlets of kitchen sinks, and side and bottom parts of the waste baskets installed under the filters or located in sink sinks kitchen.

The mud removal devices of the present invention, particularly those applied to rubber filters in the drain outlets of kitchen sinks or to waste baskets fixed thereunder, are specifically described. However, the scope of the technique of the present invention is not limited to these descriptions.

Figure 1 shows a mud removal device of the present invention. Figure 2 is an enlarged view of a part thereof. A sludge removal device of this type has a rubber filter 8, in which an annular shaped container that can be installed in the lower part of the rubber filter 8 is fixed. The rubber filter 8 has more than one rectangular hole. of drain inlet in the inner peripheral edge, more than one solution outlet hole in the inner side, and 3 pieces of clamping tabs 25 'that can hook and fix the container to the bottom of the filter. The annular shaped container whose lid and the main body of the container are firmly fixed to each other during use, has drain inlet grooves that are composed of more than one groove along the direction towards the center of the inlet tube. and that they are located in positions that extend from the upper surface of the container to the upper part of the surface facing into the container at the positions in fluidic communication with the rectangular rectangular inlet drain holes. It also has more than one circular solution outlet orifice 5 on the inner side, more than one solution outlet / outlet 26 on the outer face, more than one circular solution outlet orifice 5 on the bottom, and more than one solution outlet orifice 26 'on the outer face.

BETTER MODE OF PRACTICEING THE INVENTION

The present invention is specifically described with reference to the examples. However, the present invention is not limited to such examples.

Examples of the chemical compositions used and their tests are described in European patent application EP-A-1 676 478, which is divisive of the present application.

EXAMPLE 1

Solid chemicals, pressure molded 10 mm in diameter were prepared according to the conditions described below. 24 of them were placed in the container of the sludge removal device shown in Figure 1 which presented a radially cut rubber filter with a storage of chemical products [inlet hole of container: 6 inlet slits which They consist of 6 grooves 1.5 mm wide and 10 mm long (upper surface 7 mm and upper part of the inner side of 3 mm), and a solution solution outlet hole: 9 holes 3 mm in diameter at the bottom, 6 holes 1.5 mm wide x 5 mm long at the top of the inner side and 6 holes 2 mm wide x 3 mm long at the top of the outer side]. The mud removal device of the present invention was installed in a domestic kitchen sink for 2 months for a monitoring test.

INDUSTRIAL APPLICABILITY

The drainage sludge removal devices of the present invention can be easily installed in the upper parts of the inlet tubes and are excellent in terms of safety and handling. From a container that stores a sludge prevention / disposal agent, a solution of dissolved agent can be spread on the wall surface of a drain pipe. Because the opening areas fit both the drain inlet holes, and the solution outlet holes, only a minimum amount of water is required inside the container while the drain is flowing. A solution of dissolved chemical leaves the container even after the water drain has finished. When a conventional basket-type container is used, most of the chemicals come out along with the drain so that the agent cannot remain sufficiently on the contaminated part of the mud, without presenting any effect on the removal of sludge. In contrast, with the drain sludge removal devices of the present invention, a solution of dissolved chemical, which is not diluted with drain water, comes into contact with parts contaminated with mud for a long period of time. Therefore, a small amount of chemical effectively prevents sludge from being generated, and the impact on the environment is small even if a chlorine-type chemical is used, thanks to the fact that a very small volume of chemicals comes out in the drain. In addition, the active component dissolves at a suitable rate, so that the sludge is not only removed, but also prevented from being generated for a long time, when a disposal device is installed in a place where it is generated sludge by metabolites of various germs, molds and the like, such as drain outlets from kitchen sinks and bathrooms.
