DESCRIPTION

" AUTONOMOUS CONTAINER WITH SOLID WASTE COMPACTION SYSTEM " 1. Introduction

This equipment arises in order to solve, several problems that arise every day from the need to collect solid urban waste, whether they are undifferentiated or recyclable. The high deposition capacity, safety, versatility, mobility, allied to a low cost of acquisition and use, make this equipment ideal for uses such as urbanization, villages and small villages inland, beaches, campsites, tourist resorts, fairs, concerts or summer festivals, football stadiums, centralized points of discharge for the sweeping of large cities, ecopoints for places with large amounts of waste.

This equipment is intended to be transported in vehicles equipped with a loading arm of the type DIN 14505 and 30722, commonly known as "polybonds", DIN 30720 commonly referred to as "multibennes". or similar. 2. Introduction

In recent years, we have been collecting urban solid waste, tending to increase storage capacity at collection points, due to the fact that the population density in the urban network has increased, but also due to the need to rationalize collection circuits. 1 The protection of stored waste is also critical, avoiding the action of " scavengers " and the animals, which disperse the waste making it difficult to collect. The equipment presented here, besides having these two characteristics, allows the compaction of the deposited waste, since it has an electro-hydraulic compression mechanism (5). At this point in time nothing new, the waste compactor has been in existence for a long time, but it has the drawback of needing an electrical connection to the distribution network which limits its use on the public road, either by the need of the electrical connection point, or by the danger of its existence.

This equipment is innovative especially in its energy independence, which until today had always been the great obstacle to the use of compactors in the public road. What was done was to re-evaluate and resize the power requirements, the hydraulic group (6) and the compression mechanism (5) adapting to work at low voltage, and allowing it to be powered by solar panels. This mechanism is autonomous without requiring electrical connection to the fixed network and works at low voltage. In this way we achieve autonomy, mobility, high rates of collection and security.

In order to increase its versatility and adaptability this equipment can be connected to mains, diesel generator or gasoline, and adjustable solar panels. 2

Figure 1 shows a perspective view of a stand-alone container with solid waste compaction system according to the present invention. The reference numerals indicated refer to the following elements: 1 - guiding means; 2 - openings to dump the garbage; 3 - rear door; 4 - drum; 5 - compression mechanism; 6 - hydraulic group; 7 - solar panels; 8 - volume of compacts; 9 - instrument panel protection door; 10 - double acting cylinders for opening and closing the door. Figure 2 shows a partly cutaway perspective figure where the inner compaction mechanism in the drum with the respective pneumatic cylinder and the storage volume of the compacted waste can be observed. Figure 3 shows the schematic of the electro-hydraulic control circuit of the compaction cylinder and of opening and closing the container door (3), in which it can be seen that the control of the compaction cylinder and the control of the opening and closing cylinders The door closure is made by two solenoid valves which are controlled by the programmable controller. The reference numbers indicated refer to the following elements: 11 - Double acting cylinder for compaction; 12 - door control solenoid valve; 13 - directional control valve of the compactor; 14 - rear door control solenoid valve; 15 - pump; 16 - pressure controller; 17 - pressure regulators in the compaction cylinder circuit; 18 - unidirectional control valve. Figure 4 shows a perspective view of a stand-alone container with solid waste compaction system according to the present invention. The reference numerals indicated refer to the following elements: 1 - guiding means; 2 - openings to dump the garbage; 3 - rear door; 4 - drum; 5 - compression mechanism; 7 - solar panels. 3. Characteristics The basic equipment consists of a container consisting of the following main elements: • Drum (s) (4) • Compression mechanism (5) • Solar panels (7) • Accumulators 4 • Accumulator charge controller • Group electro-hydraulic (6) • Electrical power and control cabinet (protected by an anti-vandalism door) • Door (9) protecting the electrical cabinet. The equipment was designed to be placed on the public road with no access restrictions for its use. The placement of the control gear will be so high that it will only allow operation by adults, although its use by children is not problematic. Its operation is extremely simple, the control being executed automatically, preferably by a programmable automaton. A set of instructions transmitted by light signals (LEDs) were designed to facilitate their first use and are:

Information

Green signal - Operational equipment;

Yellow sign - Equipment in operation;

Red signal - Equipment out of service (eg due to lack of electrical charge in the accumulators or being full of garbage).

Operation

With the green light, press the black button to open the drum.

Lift the drum and deposit 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 5 2.2 m, and each drum has a diameter of 0.470 m, a length of 0.730 m therefore a capacity of about 130 liters. The storage volume (8) of the compacted waste has a variable capacity of 12-30 m 3. 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 the longest possible period of time, as its load is constant it is already preloaded .

Users are depositing their garbage following the procedure described above, until the garbage accumulated in the container raises the compaction pressure up to 3/4 of its maximum limit and is detected by a pressure sensor. At this point an SMS is automatically sent to the exchange (with modem communication system), indicating that the equipment has reached 3/4 of its maximum capacity and that it is necessary to collect it. With the continuous use the equipment will eventually reach its maximum operating pressure, which will cause the deposition drum (4) to lock, when the red signal of the condition of the equipment lights up, and another SMS to the control unit with the that the equipment is full.

If the compaction cycle takes longer than expected, the equipment will switch on the red signal and an SMS will be sent to the control panel informing that the equipment is defective. If the battery voltage is less than 6 preset thresholds, an SMS will be sent informing no load.

Once filled, the equipment is collected and taken to the appropriate place. The hydraulic opening of the tailgate (3) conveniently allows it to be discharged into a landfill or into the pit.

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

The panels used, will be of superior quality and resistance, resisting even 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 the compaction of paper / carton on one side, and packages on the other.

The following claims further represent preferred embodiments of the present invention.
