DESCRIPTION

Device and procedure for reducing bad odors for garbage containers. Object of the invention

The scope of industrial application is that of garbage storage containers that are subsequently dumped into a collection truck. By capacity, they are usually containers of about 1000 liters. The object of the present invention application refers to a device that including different elements allows the bad odors that are usually associated with the presence of containers on the public highway to be significantly reduced, especially with elevated temperatures associated with the summer season. As is well known, this is a particularly unpleasant problem for pedestrians, when there is also little natural ventilation in the environment of the container.

To solve this problem, the manufacturing process of garbage containers is modified: First, by creating siphon-shaped grooves or perforations for the entry of air into the lower part of the main body of the container. And second, creating an air outlet at the top or lid, to create forced ventilation thanks to the action of a small motor that will operate as an extractor and that will be powered by solar energy. There will also be a chemical doser that will neutralize the smelly particles with the help of a disposable carbon barrier or filter. The whole set should be built thinking, not only in extreme weather, but also in the face of foreseeable vandalism.

Background of the invention

There are devices or gadgets to improve the deposit or treatment of urban waste, but nothing similar to what is presented here has been found. Thus, there are devices that seek an aesthetic improvement and removal of garbage, conceal the containers or waste deposits, using electrical or hydraulic mechanisms, in the subsoil or below ground level. But, as a counterpart they involve a high cost of implantation and maintenance. There are devices where, when depositing garbage in the container, it must be done through a valve structure that allays the waste, once placed. And with respect to air extraction and odor reduction devices, those that combine the fan itself with a deodorizer that neutralizes the bad smell using gels that have a chemical composition that, once released through a dispenser, produce the bad smell absorption.

The advantage of the device presented with this application, with respect to the state of the art described, is, first of all, the low price of its implementation since it is not about burying or burying the containers, but of making a modification to existing containers. And secondly, this device offers a simple and cheap solution for the reduction of odors, since it is autonomously energized with solar energy. This implies the advantage that the more sun it does, the more effectively it will work, just when it is most needed: We know that bacterial fermentation, largely responsible for bad odors, depends on the temperature, linked in turn to the increase in solar exposure, that is, when photovoltaic panels can transmit more energy to the exhaust motor.

Description of the invention

Device and procedure for reducing bad odors in garbage containers that usually contain garbage bags with organic or inorganic material. We start with a conventional garbage container that usually has wheels with brakes, an upper lid and a main body that supports the whole assembly and that has a drain plug to facilitate internal cleaning. The device presented modifies in a characteristic way the body and the lid of the conventional container. The body is modified to create an air inlet at the bottom. And the top cover is modified to force the passage of bad odors from the base of the container. The way in which the air is forced, is thanks to the fixation on the outer face of the upper cover, of a housing-motor assembly that is fed by photovoltaic panels that extend over the entire surface of said cover.

At the same time that air is passed, first, through a disposable active carbon filter, and second, it is passed through a dispenser, which taking advantage of the venturi effect caused by the extractor, creates a nebulized mixture where the molecules of an gel, essence or product that neutralizes the particles that produce bad odors. The device is thinking so that although maintenance is poor, basic operation is guaranteed.

Brief description of the drawings

Figure 1: Conventional garbage container

Figure 2: Container with odor reduction device (perspective)

Figure 3: Container with odor reduction device (section) Description of a form of realization

In view of Figure 1 the device is described as follows: We start from a conventional container, which is essentially composed of: A lid (1) that is usually opened upwards, either manually or by stepping on a lever. A main body (2) where the garbage bags are poured, with some lateral projections for the elevation and unloading of its contents in the garbage truck. Normally there is a drain plug (3) in the base for easy cleaning. And it has wheels that support the whole set, wheels equipped with brakes, to prevent accidental displacement of the container, for example, by wind action or by the slope of the street.

In view of Figures 2 and 3 the device is described as follows: Starting from Figure 1 above, where the conventional garbage container is described, the following is done:

First, the upper cover is modified (1) Photovoltaic panels (5) of the maximum available solar performance are attached to the cover, according to the state of the art of the moment, with the possibility of giving them, interposing the necessary regulation piece, an orientation and optimal solar inclination (latitude of the place. plus ten degrees in winter and less ten degrees in summer) These photovoltaic panels will feed a rechargeable and renewable battery, which in turn will feed an extractor motor (8) of variable power, to

be able to operate with the predictable ups and downs of energy supplied by the photovoltaic panels. In addition, the extractor motor will have attached a doser of products, essences or gels that neutralize odors (9) and can be filled periodically. In the lid itself there will be an active carbon filter (7) through which the air is also circulated and can be periodically renewed. The engine, battery, dosing and carbon filter assembly will be housed inside a housing (4) that will have an aerodynamic shape so that the air leaves the container with the minimum possible turbulence and an outlet that prevents rainwater , enter inwards. All the elements will be manufactured to withstand the weather and also preferably vandal acts. The odor neutralizing gel dispenser is activated by venturi effect when the air current generated by the extractor passes over some slots to the effect incorporated by the doser itself.

Second, the main body (2) is modified by placing on its sides, near the base of the container, air inlet elements (6) that take air from the outside to make it pass inwards. and later, with the action of forced ventilation, return it to the outside already purified by the action of the active carbon and by the action of the gels or essences neutralizing the bad smell. These air inlet elements (6) hide a perforation that carries the main body of the container (2) to ventilate it. To prevent part of the contents inside the container from leaving, these air inlet elements are placed, which force the air to pass through a kind of "air siphon", and prevent the perforation or air inlet slot, is clogged by the accidental pressure of the garbage bags. Said air inlet elements (6) carry a curtain that serves as an anti-return element of odors to the outside, so that if there is no air suction, from the inside out, the air inlet hole is closed to avoid that the bad smells go out through the ventilation hole. The whole set is regulated by a control and control center with a bad smell sensor and that will allow, in addition to the obvious shutdown or disconnection of the entire device, a continuous or discontinuous operation procedure.

Continuous operation: At night, the extractor motor (8) operates until the battery runs out. Of this, a part of the energy generated by the photovoltaic panels recharges the battery, and another part of the energy generated by said panels drives the extractor motor.

Discontinuous operation: When a sensor designed for this purpose detects a bad smell inside the container, according to a predetermined threshold, the extractor motor will be activated, and otherwise it will remain off recharging the battery if it is a day, or maintaining its charge if it is night .

The operation of the extractor, in addition to causing an evident ventilation, implies the action of the active carbon and the doser that is combined with the malodorous air to be neutralized by the action of gels, essences or any product, for example, by fogging using the effect venturi
