WO2019139464A1 - Autonomous mechanical system for collecting domestic refuse and waste - Google Patents

Abstract

The autonomous mechanical system for collecting domestic refuse and waste involves a method for collecting and transporting domestic refuse and waste over short or medium distances; it improves a standard collection system based on refuse collectors passing through virtually every neighbourhood in order to empty waste containers placed close to houses and at the corner of each street or avenue into trucks or the like, with the purpose of removing the contents thereof to the dump. It is a mechanism for carrying domestic refuse and waste from one point to another in an underground culvert and automatically and autonomously to a collection point centralizing one or more neighbourhoods at a time. This system is made up of: 1- Fixed hermetically sealed collection containers that replace the standard movable containers; they will be located so as to be within range of "civilian" users in residential areas and the like; they are designed to receive and swallow up the refuse and waste in the "collection vessel" lower part thereof. 2- A network of underground culverts in which conveyor belts are positioned that transport the waste to the waste disposal site. 3- A semi-underground or underground waste disposal site for intermediate collection between the neighbourhood(s) and the dump. The process of conveying refuse is activated automatically and autonomously once the container collection vessel has reached a given quantity or a certain volume or weight set as an activation setpoint, the operation of transporting the refuse via conveyor belt to the intermediate collection site begins. From one collection container to another, the refuse is transported to the intermediate collection destination, this making it possible to empty the collection vessels in order to receive further quantities of refuse and waste. In the intermediate collection site where the refuse from one or more neighbourhoods is collected, all of the refuse and waste packaged and compressed in hermetically sealed sacks by virtue of a machine is collected by truck or the like in order to be evacuated in an odour-free manner to its final destination: landfill, processing or incineration.

Description

 Autonomous Mechanical System for Waste Collection and

 Household Garbage

1-Description:

introduction

 The household garbage is collected in all the communes and urban agglomerations of the world at least once a day. It is an operation that requires huge resources in material! and in budget, which vary according to the size of the population density.

 Studies show that an individual produces between 0.900 and 1.400 kg of waste on average daily. The collection points are real nuisances as much by the smell they give off as by their unpleasant appearance.

 Household waste is incessantly generated in increasing quantities with the development of the way of life of societies. They are heterogeneous and their quantitative composition varies according to the space (from one society to another, from one country to another, from one city to another, from one household to another , etc.) and time (days of the week, season, year, etc.).

 Geographical, climatic, economic and demographic factors are decisive in the quantification of waste generated by a community.

 Knowledge of the amount of waste produced in a given environment is essential for planning a management system in order to better predict the amount of garbage containers for each neighborhood and the means of transport to the places of storage of this waste.

 The quantities of waste produced per capita in some cities in developing countries are shown in the table below:

Technique de collecte Actuelle

Current collection technique

 The collection is generally done in all neighborhoods, the employees responsible for this mission pass virtually in all neighborhoods to empty large bins and containers in trucks.

Objectives of the invention

 The purpose of developing this collection system is to:

 1- Permanently stop the passage of garbage trucks in some neighborhoods and reduce it to a minimum in others.

 2- Reduce and centralize the points of collection and collection of waste using trucks

 3- Automate and empower the collection and transport of waste

 4- Optimize transport

 5- Obtain a saving of energy and effort

 6- Preserve and protect the environment.

The Automatic Garbage and Garbage Collection System has several steps

1 ^st * step

 Recovery Container (Drawings # 1)

 The container must be placed close to the houses and comes to replace the big bins classics it comprises two parts: a- A visible part except stupid including (Drawing n ° 2):

 1 - A fixed container hermetically isolated by a rotating propeller system downwards (Drawing n ° 4)

 2- An electrical box for system control and anomaly detection

 3- A trap door for maintenance and repair operations b- An underground part composed of (Drawings 4 and 5):

 1- A basement bin for waste recovery

 2- A detection and start-up system connected to an adjustable sensing probe to determine the amount needed to trigger the system.

3- An electric motor connected to a gearbox. 4- A treadmill with stretches extendable downward to sweep the waste that falls into the gutter and bring them back to the starting point.

 5- A look of recovery of iixiviat provided with a vacuum pump cellar connected to the sewers.

6- A worm system to put the swept waste from the gutter back to the recovery tank.

C- Hermetic seal with recovery container propeller (Drawing n ° 3)

 In order to insure the insulation against the rising of odors, the recovery container inspection hatch is equipped with a hermetic impeller insulation system which operates so that the next pay comes close the opening at each once a quantity of waste is placed on the lower pay of the propeller. It was rotated by a quarter of a turn to empty the waste into the recovery tank located under the container.

 The blade tips are made of rubber and a spring adjusts the engaging weight of the process.

^2nd step

 Waste routing

 Once the tank is filled to the desired level, the level sensor triggers the waste routing process with a conveyor belt located in a gutter connecting one point to the other to the final recovery room. {Drawings nº4).

 The treadmill will route the waste to one or more intermediate recovery points (Drawing # 9) between the starting point and the final recovery facility (Drawing # 7). These points have the same functionality as the starting point and the same principles of operation. They will in turn drive the garbage to other points to the final collection site.

^Step 3

 Final collection

 From point to point as needed, distance and availability, trash will be conveyed by treadmill in the underground network to the final collection point (Drawing # 7).

 A basement room large enough to house evacuation trucks to the dump or to a waste incineration plant.

Once arrived, the waste is directly thrown in a machine to either compress or grind it in order to reduce their volume and put them in bags hermetic or vacuum. The machine will pile them into containers that will be loaded onto the trucks.

When the containers are full a signal is sent to a central that manages the logistics for the deployment of the waste recovery trucks and the replacement of the on-board containers.

_{4th step}

Self cleaning system of gutter

 The treadmill is equipped with several blades {Drawings n ° 8)

 Once upside down, an extensible broom sprung by gravity (Drawings 13 and 14).

 These pennies have the role of shoveling waste.

 It allows the trash to be swept back into the gutter and back to the point of departure.

 This waste falls directly into a small recovery tank located at a low level at the end of the gutter and a worm up to the main tank to undergo the same process (Drawing No. 11).

Selective sorting:

 The Autonomous Mechanical System for the collection of waste and garbage can possibly meet the needs and actions of selective sorting by a range of recovery containers designed specifically to receive waste according to their nature (Drawing n ° 12). The routing process will vary from that of other waste, the recovery tank is divided into three parts (Drawing # 13)
