FR2807083A1 - Communal refuse sorting system, for multiple occupancy buildings, has chute access trap in each apartment and basement collection bins for each refuse category - Google Patents

Abstract

On every floor (E1,E2,E3), each apartment ha a sealed trap (3) concealing a branch duct that leads (2) into a common chute (1), running vertically down to a routing box (4) in a ground floor or basement compartment. Access traps are conveniently placed e.g. in kitchens, balconies, etc. and opened by push-button control pads (7). Having sorted the refuse, typically into 3 plastic bags, the householder opens the trap with the category button corresponding to the contents of the next bag to be dispatched. This actuates the appropriate exit shutter (6) in the routing box, so that the bag falls through the correct delivery channel (4a,4b,4c) into its collecting bin (5a,5b,5d). Bins are fixed receptacles, whose contents are periodically removed (5c) by suction; wheeled bins (5d) are used. Bins have comminuting (9) and/or compacting facilities. Discriminatory control push-buttons are omitted, and a sensor (8) identifies and correctly routes the sorted refuse automatically. Also, induced draught fans (10) assist gravitational flow. Deodorant and disinfectant treatment (11,12) may also be installed at the top of the chute.

Description

<U> INSTALLATION </ U> OF <U> DISPOSAL </ U> HOUSEHOLD WASTE <U> IN BUILDINGS. </ U> The object of the invention is related to the technical sector of means of evacuation of garbage in buildings, garbage type.

For many years, garbage disposal facilities have been known in collective buildings which, from a hatch located upstairs or between two floors on the landing, or even in a loggia or balcony, evacuate household waste by a column communicating with bins housed in a suitable room on the ground floor or basement of the building.

Recently, to facilitate the further processing of waste and garbage in collection stations, and to meet the new standards of hygiene, have appeared the specific bins or containers for sorting this waste from large families, namely: paper, plastics, glasses ..... These selective containers are either collected in a dump with regard to the rural world, or distributed in various points of a city, or still provided directly at the level of a building in a local or outside.

While this selective sorting of garbage constitutes a definite improvement over previous installations, it proves difficult to implement mainly because it obliges users not only to first sort their waste, but above all it requires transport them once sorted in garbage bags from the housing to the place of storage and collection, in this case the appropriate container. This constraint can be misunderstood or even very difficult for some people with reduced mobility. Moreover, it requires going to places that are often difficult to access, unhygienic, unsafe or offering no security for vulnerable people if these containers are outside and sometimes far enough away from the building.

The installation according to the invention overcomes these drawbacks in that it prevents the user from handling several bin bags selected container from its housing to the storage and collection points, it meets the new standards in the area of the environment, particularly in terms of sanitation and can be implemented in both existing buildings and new buildings.

To solve the problem of waste handling, the installation according to the invention comprises in known manner in each building at least one waste transport column communicating with one or more bypass ducts and terminated by an access hatch for each landing or each apartment.

According to a first characteristic, the installation is equipped with an automatic waste selection device introduced into the trough or troughs, whether these wastes are unitary, or grouped by family at the start, said selected and evacuated waste being then stored in containers. specific containers distributed around and at the lower end of the column.

To solve the problem of selection of the waste to be evacuated in the column or void of garbage of new or existing buildings, a manual or remote controlled device of the housing type comprising as many control buttons as there are families of waste, is arranged at each landing or in each apartment, near the hatch; this device, when activated, allowing the opening of the entrance door of the waste previously sorted by the user. For new constructions, the waste selection device is of the automatic type, in the form of a cell located at the bottom of the column and recognizing the nature of the waste sorted by family and introduced into said column.

To ensure the selective storage of sorted waste arriving at the bottom of the column, a multi-way and valve switch is arranged at the lower end of the column, the different channels each cooperating with a suitable container.

To increase the volume of waste storage, grinding or compaction means are inserted between the routes of the switch and the containers.

To avoid handling full containers, an evacuation device is provided at the base of the containers in connection with a vacuum fitted to garbage collection vehicles.

To further improve the operating conditions of the installation, waste suction turbines are mounted in the inlet chutes or at the base of the column.

To ensure better hygiene and remove unpleasant odors, a blower is located at the top of the column, this blower diffusing a deodorant or disinfectant product.

These and other features will become apparent from the following description.

To fix the object of the invention, without however limiting it in the accompanying drawings # 1 is a schematic sectional view of an embodiment of the installation according to the invention in a new building. # Figure 2 is a detailed view of the control box or remote control selection of waste.

 Fig. 3 is a cross-sectional view taken along line 3-3 of Fig. 1, showing an example of selective waste storage.

In order to make more concrete the object of the invention, it is now described in non-limiting embodiments illustrated in the figures of the drawings.

Figure 1 shows schematically a sorting facility for household waste applied in a new building.

In this example each stage (E1, E2, E3 .....) is crossed by at least one column (1) for two apartments, if this is technically possible. Access to the column is made by derivations in the form of chutes (2) opening into a specific place of the apartment (kitchen, loggia, balcony ....) and closed by a hatch (3) preferably waterproof and lockable by any means. At the bottom of the column, a switch (4) to several channels (4a, 4b, 4c, ....) allows the disposal of waste in one of the containers (5) provided for storage. The occupant of the apartment wishing to throw his waste through this door must first optionally sort them by family (paper, plastics ....) and throw them as they are in the chute. For this, it acts on a manual selection box (7) or a remote control comprising as many buttons (7a) as there are families of waste. This housing is disposed near the hatch on the landing or in the apartment. The activation of this command then allows the unlocking of the hatch and automatically opens one of the valves (6) placed between the switch (4) and the containers (5), thus ensuring the passage of selected waste in the appropriate container. In practice, there is a triple selection or family, namely: paper, plastics and other household waste. However, it is not excluded to add others such as glass, wood, fabrics ...

Alternatively, it is also possible to provide automatic selection of waste either at the level of the user by the control box, but directly at the base of the column before the switch (4). For this, the user manually opens the hatch (3), throws the waste of the same family in the chute. At the bottom of the column, this waste passes a cell (8) which recognizes the nature of this waste and then controls the opening of the valve (6) corresponding to the specific container of this type of waste.

Of course, the shape of the switch, in particular the channels (4a, 4b, 4c ......) is studied to ensure complete evacuation, without the risk of stagnating waste in the switch or between two tract.

In order to increase the storage capacity of the containers, provision is also made for means (9) for grinding the waste that is either inserted between the switch channels and the containers, or integrated into the containers at the top. It is also possible to provide compaction means (not shown).

These containers are either fixed (5a, 5b), the waste they contain then being discharged through a connection (5c) to the lower part by suction using a vacuum fitted to the collection vehicle, or movable (5d) for manual evacuation of said container.

To further improve the disposal of selected waste suction turbines (10) are mounted either in the inlet chutes, if they are offset from the main column or at the base of the column.

On the other hand, to ensure better hygiene and remove unpleasant odors, a blower (11) is arranged at the top of each column, or a blower common to all columns of the building. This blower is equipped with a member (12) for diffusing deodorant or disinfectant product.

It should also be noted that the switch (4) is of the type with an S-shaped molded tube, that it is perfectly sealed and resistant to compression and to the different air flows to which it is subjected, and that it can be suitable for wall or ceiling mounting following the site.

The advantages are apparent from the description, it emphasizes the flexibility of use of this type of installation that avoids the occupants of a building to handle selected waste from their apartment to a receptacle at the bottom of the building or away from the building; the sanitary improvement obtained with this installation compared to the old garbage chute because of the contribution of automatism and electronics allowing the implementation of disinfectant products by diffusion at the top of the evacuation columns, the possibility by means of minimal transformations, adaptation in existing buildings with conventional garbage disposal.
