EA015585B1 - Sanitary plumbing device for protection sewerage system from clogging - Google Patents

Abstract

The invention relates to plumbing devices in fresh and waste water for use inside buildings, more definite to inserts, collectors etc and can be used in municipal public water supply for protection sewerage system from clogging. A sanitary-technical arrangement for separating solid wastes from waste waters comprises an upper input sink (1), to a drainage pipe (2) of which a garbage-collecting bag (4) is fixed by its neck, the bag is freely hanging down into a lower input sink (5) connected to the sewerage system. A knitted bag (a golf type) is manufactured at a universal hosiery knitter, pass water freely and reliably collect rubbish (solids, sand, food wastes etc.). Upon the filling the bag is stretched out thus increasing its volume by several times. It further can be easily removed and utilized with solid wastes, or emptied for repeated use.

Description

The invention relates to plumbing installations for fresh and waste water used inside buildings, and more specifically to inserts, collectors, etc. devices in drain devices for garbage collection, and can be used in urban utilities. The device can be installed in public buildings, such as train stations, airports; in catering points, cafes, restaurants; in kitchens of residential buildings for the separation of municipal solid waste (MSW) from wastewater.

There is a known sump under the sink for collecting solid waste (ΙΡ 2006336245; Е03С 1/26; 2005), where solid debris is deposited on the bottom of the container, and the liquid flows through a siphon into the sewer network.

The disadvantage is that the container requires regular cleaning and disinfection, as it provokes stagnation and decay.

A construction is known (ΙΡ 59160591; С02Е 3/00; 1983] for multi-stage filtration of wastewater in the form of a barrel, at the entrance of which a mesh bag for collecting solid waste is built in. It is used in collectors, but not inside buildings.

Known sink (SI 2706523Υ; E03C 1/264; E03C 1/26; 2003) with a mesh bag for filtering, which is inserted into the drain hole from above.

A disadvantage of the known designs is that the size of the mesh bag is small and limited by the inner diameter of the pipe, and also requires frequent emptying and cleaning.

The objective of the invention is to ensure the reliability of the separation of municipal solid waste from liquids in the drain devices for wastewater, i.e. creation of a device that is reliable in operation, cheap to manufacture and easy to use.

The invention is illustrated by drawings, where in FIG. 1 shows a static state, and FIG. 2 shows the state during operation.

The device consists of an upper inlet 1, a drain pipe 2, a knit filter retainer 3, an empty knit filter 4 in FIG. 1 and a knitted filter filled with municipal solid waste and a bottom outlet 5 in FIG. 2.

The problem is solved in that the proposed sanitary-technical device for separating municipal solid waste from wastewater consists of an upper inlet sink, to the drain pipe of which a removable filter for collecting municipal solid waste is attached with a neck. The filter hangs freely in the lower outlet, connected to the sewer, and is a knitted bag made on a standard hosiery.

Comparison of the claimed technical solution with known solutions from the prior art did not reveal similar solutions, which allows us to establish its compliance with the criterion of novelty.

The proposed device is industrially applicable, and the developed technical means meet the criterion of inventive step, since they do not explicitly follow from the prior art.

Moreover, from the last, no transformations, characterized by distinctive essential features, were found to achieve the specified technical result.

The device is assembled as follows (see Fig. 1). An existing sink 1 is disconnected from the sewer and a second outlet sink 5 is installed under it, the drain pipe of which is connected to the sewer, and a latch 3 of the knit filter neck is installed on the drain pipe 2 of the upper shell 1. The filter 4 is made in the form of a bag of knitted material (type golf) and hangs freely in the lower outlet sink 5.

These accessories 3 and 5 can be stamped from cheap plastic. Knee socks used as a knit filter 4 are available in retail. But it is better to knit the knitted bags on a hosiery knitting machine from a special thread made of biodegradable plastic.

The spiral flow of water with mud (see Fig. 2), under the action of the Coriolis force from the inlet 1, rushes into the drain pipe 2, is screwed into the knitted bag 4, stretches it several times and rams the dirt in it into a dense lump weighing up to several kilograms. And water, losing energy and speed, freely seeps between the loops and drains quietly without spraying on the outer surface of the bag into the sink 5 and further into the sewer.

Knitted weaving loops volumetric, i.e. the loops and the gaps between them are bent in three coordinate directions. In addition, the thread is twisted, which allows the product to stretch in volume. This is a special property of knitted weaving and is used as a barrier to solid waste, earth, sand, food waste. Curved loops trap quite small fractions of debris. A knitted bag allows water to pass through and reliably retain solid waste. As it fills up, it is easily removed and disposed of with solid household waste, or emptied and can be reused.

Claims (1)

CLAIM Sanitary-technical device containing two sinks installed one under the other, and a replaceable filter for separating solid household waste from waste water, while the filter is made in the form of a bag of knitted material attached by the neck to the drain outlet of the upper sink, designed to receive the cleaned waste water that can increase in volume as it is filled with waste and hangs freely in the lower sink, the drain pipe of which serves to connect to the sewage system.
