Abstract

The present invention shows a container with a solid waste compacting system having hoisting means (1) for lifting the container with a loading arm of a waste collecting vehicle, or an equivalent hoisting device, the container having one or more garbage discharge openings (2) and a rear waste discharge door (3), and also one or more waste storage drums (4) for and a garbage compression mechanism or mechanisms (5) in each drum. The solar panels (7) of which the container is equipped supply electric energy to the electro-hydraulic compression mechanisms (5) and charge the electric energy accumulators. The system thus has a long operation autonomy and can additionally comprise generator assemblies or a wired connection to the electric grid.

Description

DESCRIPTION

"AUTONOMOUS CONTAINER WITH WASTE COMPACTING SYSTEM

SOLID "

1. Introduction

This equipment is designed to solve various problems that arise every day from the need for collection of municipal solid waste, whether undifferentiated or recyclable.

The large deposition capacity, safety, versatility, mobility, coupled with low cost of purchase and use, make this equipment ideal for uses such as: urbanization, inland villages and villages, beaches, campsites, holiday villages, fairs, concerts or summer festivals, football stadiums, centralized unloading points for sweeping large cities, ecopoints for high waste sites.

This equipment is intended to be transported in vehicles fitted with a loading arm of type DIN 14505 and 30722, commonly known as "polybennes", DIN 30720 or "multibennes" or the like.

2. Presentation

In recent times, in the collection of municipal solid waste, there has been a tendency to increase the storage capacity at collection points. collection circuits. The protection of stored waste is also crucial, avoiding the action of "pickers" and animals, which disperse the waste making it difficult to collect.

The equipment presented here in addition to having these two characteristics allows the compaction of the deposited waste, as it has incorporated an electro-hydraulic compression mechanism (5). At this point nothing new, the waste compactor has been around for a long time, but it has the disadvantage that it needs an electrical connection to the distribution network which limits its use on the public road, either by the need for the electrical connection point, because of the danger of its existence.

This equipment is innovative especially in its energy autonomy, which until today had always been the major obstacle to the use of compactors on public roads.

What was done was to reassess and resize the power requirements, adapting the hydraulic group (6) and the compression mechanism (5) to work at low voltage, and allowing it to be powered by solar panels. This mechanism is autonomous and does not require electrical connection to the fixed network and works at low voltage. In this way we achieve autonomy, mobility, high collection rates and safety.

In order to increase its versatility and adaptability this equipment can be connected to the power grid, diesel or gasoline generator, and adjustable solar panels. Brief Description of the Figures

3. Features

The basic equipment consists of a container consisting of the following main elements:

• Drum (s) (4)

• Compression mechanism (5) Solar Panels (7)

Accumulators

Battery charge regulator

Electrohydraulic Group (6)

Power and control switchboard (protected by an anti-vandalism door)

Protection panel door (9).

The equipment has been designed to be placed on the public road without access restrictions for its use. The placement of the controls will be so high that it will only allow operation by adults, although their use by children is not problematic.

Its operation is extremely simple, the control being executed automatically, preferably by programmable automaton. It was designed a set of instructions transmitted by light signals (LED's) to facilitate its first use and which are:

Information

^■ Green light - Operational equipment;

^■ Yellow light - Equipment in operation;

^■ Red light - Equipment out of service (eg due to lack of electrical charge in the accumulators or being full of trash).

Operation

^■ With the green light, push the black button to open the drum.

^■ Raise the drum and dispose of the trash bag.

^■ Close the drum. In its preferred embodiment the container has a length of 5.5 m, a width of 2.5 m and a height of 2.2 m, and each drum has a diameter of 0.470 m, a length of 0.730 me therefore a capacity of about 130 liters.

The storage volume (8) of compacted waste has a variable capacity of 12-30 m3.

4. Operation

The equipment is installed on the public road, for example in a garden, or in a parking space, where it can receive solar radiation for as long as possible, since its charge is constant, it is already previously charged.

Users will deposit their waste following the procedure described above, until the accumulated waste in the container raises the compaction pressure to 3/4 of its maximum limit, being detected by a pressure sensor. At this point an SMS is automatically sent to the central (with a modem communication system), signaling that the equipment has reached 3/4 of its maximum capacity and that it is necessary to collect it. Continued use of the equipment will eventually reach its maximum operating pressure, which will result in the locking of the deposition drum (4), the red status signal of the equipment lighting up, and a further SMS to the control panel. information that the equipment is full.

Claims

In the event that the compaction cycle takes longer than expected, the equipment will light up red and an SMS will be sent to the control panel stating that the equipment is malfunctioning. If the battery voltage is below a pre-set threshold, an SMS will be sent informing you of a charge.

Once filled, the equipment is collected and unloaded at an appropriate location. The hydraulic opening of the tailgate (3) allows for convenient discharge into landfill or pit.

Although the system is so simple that its probability of failure is extremely low, there is the possibility of internally connecting a parallel supply system to operate the equipment.

The panels used will be of superior quality and strength, even resisting the projection of stones. In any case they are placed, barely visible and protected against acts of vandalism or even theft.

This equipment may be for single or bi-flow packaging, having for this purpose two compression mechanisms and two independent containers for use for example in paper / board compaction on one side and packaging on the other.
