Description

DRY HUMAN WASTE EVACUATION SYSTEM THAT ELIMINATES 100% THE USE OF DRINKING WATER OR ANY KIND OF WATER IN A

TOILET. SCOPE

The present invention provides a system for evacuating feces and urine from the toilet (WC) without the intervention of water in the system, more specifically a dry human waste disposal system that eliminates 100% the use of drinking water or any type of water of water in a toilet.

DESCRIPTION OF PRIOR ART

Throughout history the disposal of human waste has been a problem because they are a focus of infections, bad odors and the origin of pandemics if they are not treated properly. From relatively soon, the man was aware of the unhealthiness of being exposed to his own and the most primitive peoples were already careful to at least move away from the places of housing to meet their needs.

The point is that, as population density increases, this solution does not work. If a small number of people live in a large area, it is feasible. However, with the emergence of the first population centers, eliminating excrement began to become a real problem - not only because of the discomfort, lack of privacy or smell, but also because of the problem of contamination of drinking water and water. spread of infectious diseases.

The first solution to this problem, well before any sewage system, was the latrine: a hole in the ground, usually inside a small structure to provide privacy. Often, the hole led to a more or less large chamber. When it had been filled, it closed and opened another one on another side, and so on and on. In some places, latrines were collective; in others, each family nucleus had its own.

The latrine, although it is a simple technological solution, still poses problems, all the more the higher the population density. The problem is exacerbated because, although it seems a lie, the gases released by the latrine well are potentially dangerous. Hence, most of them are built outside buildings and with good ventilation. The second problem is the possible contamination of drinking water. Many cultures drank from springs or wells near their homes, and excavated a well to store excreta, which could eventually filter the Organic waste to nearby water sources and contaminating the supply was serious, since it could bring many complications. This is because when it rains, water seeps through the ground until it reaches the water table, crossing the well.

The old cisterns and sewage systems were services with running water that eliminated excreta through sewers. It was not a perfect system, but it eliminated the main problems of the latrines: the water carried the feces away and did not allow the gases to accumulate where there were people.

Already in the sixteenth century, John Harington described, in 1596, a predecessor of the toilet that was emptied by a valve (which he called "The Ajax"). Ajax still had a problem, apart from the noise it could make: unless a huge amount of water was used, or that it was running continuously, the reflux of contaminated water was almost inevitable, and the smell unbearable. In order to have such systems in homes, it was necessary to develop a mechanism that made it impossible for the smell to come back out. The solution was given by Alexander Cummings, a watchmaker from London, in 1775 with his patent No. 814: the siphon. The system is simple but efficient, and consists of an S-shaped pipe. When the water passes through the siphon, the bottom of the S always remains with some water, which acts as a hermetic closure of the rest of the pipe. In this way, the gases that may be "on the other side" cannot leave, and it is possible to install the whole invention in the house. Hence the name of the toilet: after Cummings, the smell would cease to be an insoluble problem.

The particularity of the toilet is that it has an angled drain, so that water is retained in it, forming a hydraulic closure or siphon, which prevents the passage of unpleasant odors. The hauling of organic matter to sanitation requires a device that produces a discharge of large water flow in a very short time, leaving nothing more than clean water in the elbow of the hydraulic seal. This device can be a cistern or a special valve called a flowmeter.

The cisterns, which can be high (fixed to the wall at a height of almost two meters) or low, have a filling mechanism, with a level valve, which cuts the water inlet when it reaches a certain level, and of another download, operated by the user. Because of its position, the high cistern requires less water to operate.

However, when someone decides to use the toilet, they are inevitably contaminating the water. It is estimated that a family of five who use it pollutes more than 150,000 liters of water by transporting about 250 kilos of feces and 2500 liters of urine in a year. However, it is the least polluting method of eliminating human excreta, especially when it is dumped into a sewer system that ends up in an urban purification system (WWTP). Any other method pollutes more and more L2017 / 000005 less controlled.

Therefore, it is necessary to develop toilets that do not use water discharges for emptying.

BRIEF DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION OF THE INVENTION

The present invention has been developed based on existing technology in the market to evacuate the toilet or WC but does not require water. The system seeks to redesign / re-invent the WC and how a traditional toilet works and how the waste arrives in the sewage sewage system, eliminating 100% the use of drinking water or 7 000005 of any type of water.

As Figure 1 shows, the evacuation system (100) of human wastes without water is designed for operation in residential and commercial locations and emulates the operation of the toilets of passenger airplanes. It includes a redesigned toilet (1) that is shaped like a conical shaped cylinder that is bent or curved inward, as it moves towards the bottom of the toilet. Unlike the traditional earthenware bowl, which is extremely porous and that by design serves to "evacuate by sweeping" by large displacement of water, the toilet (1) has a curvature in its design that offers a minimum contact surface, something similar to a funnel, to reduce the contact surface and thereby adherence. It also uses an ad hoc material for its inner surface that makes the adhesion of waste (toilet paper, feces mixed with urine) much more difficult to produce. This is because: it offers a smaller contact area than traditional bowl-shaped toilets; and the material with which the interior of the waterless toilet is manufactured in the form of a conical cylinder (similar to a funnel) curved, can be stainless steel, such as airplane baths. This offers a minimum (almost null) degree of adhesion or can also be made of cheap plastic or polymer material. If it is made of plastic, the inside of the toilet should be coated with a layer of non-stick or non-stick paint or varnish (those that are commercially available) to prevent debris from adhering to the surface when in contact with the toilet (1). This paint or coating is currently used for other uses, is cheap, lasts a long time, and requires minimal maintenance.

The evacuation system (100) of human waste without water, integrates a vacuum pump (13) of variable size, depending on the scalability of the system to be installed. One option is to have a small side channel vacuum pump with a capacity of 200 to 250 cubic meters per hour (m ³ / h), as used in the prototype, to operate a single toilet (1). In this case, the power of the vacuum pump is sufficient to expel the waste into the sewer pipeline, as part of their suction process. For this reason the design for a toilet located very close to the sewer pipeline does not need an intermediate compression valve (14), being able to complete the evacuation process only with the suction power of the pump (13). However, the evacuation system (100) of human waste without water also has the design option in which two or several toilets (1) are connected to a single vacuum pump (13) with adequate capacity and power. In this case, the vacuum pump (13) is still of the side channel type but must have a suction capacity of at least 800 m ³ / h. The vacuum pump (13) performs the suction process of one or several toilets at the same time (depending Of demand). Each of the toilets will be connected to a pipe or pipeline (5) of PVC or similar material, which in turn is connected to the vacuum pump (13) with intake for each toilet. The operation of each toilet (1) is independent of the others and operates by an electronic signal, coming from a controller unit (7) that activates the vacuum pump (13) for evacuation by suction. The capacity of the vacuum pump (13) in this case must be such that it allows you to operate one or several toilets (1) at the same time, depending on the demand at a given time. To do this, it must be able to display a vacuum suction capacity (work) that varies in a range determined by the capacity of the vacuum pump (13). In this way, to evacuate two or more toilets (1) at the same time, the vacuum pump (13) when required, deploys a greater or lesser suction force by means of a variable pressure difference controlled automatically by the controller unit (7).

The evacuation system (100) of human waste without water operates each toilet (1) automatically, once the user has finished using the toilet. It does so in two possible ways: a) through an electronic sensor (11) that detects the discharge of the waste into the toilet or b) through manual activation with a pedal or button (3).

The toilet (1) has at the bottom of its structure (at the base) an outlet connection where the waste is sucked. This opening comprises a valve (2) or outlet gate that automatically opens and closes the controller unit (7), opens for suction and closes after vacuum suction performed by the vacuum pump (13). Therefore, the outlet valve (2) located at the bottom of the toilet (1) is part of the integral evacuation circuit and is directly connected to the vacuum pump (13).

The conical cylinder-shaped toilet (1) that collects waste through which feces and toilet paper are sucked, is connected to a pipe or pipeline (5) of PVC or similar material, which in turn is connected to the vacuum pump (13). The toilet (1) without water sucks and expels waste through that pipeline or pipeline (5).

In the case of operating an evacuation system (100) of human wastes without water with two or more toilets connected to the vacuum pump (13), as would be the case of a public restroom in a shopping center or university, by For example, the design is different. In this case it is required that it also incorporates an intermediate compression valve (14) that is part of the pipeline itself (5), and that is located after a vacuum chamber (6). This vacuum chamber (6) is where the vacuum is produced by pressure difference of the system to perform the suction. The intermediate understanding valve body (14) comprises a spring and a compression nut, with an intermediate shaft, if if necessary, and is available in the market. This intermediate compression valve (14) that is located just towards the end of the PVC pipe or pipe (5) (where the waste is sucked like a bulb) has the function of providing the suction system with an additional capacity to expel waste to the sewer (15). The intermediate compression valve (14) must be located just before the connection of the PVC pipe or pipe (5) with the drain to the sewer (15).

The intermediate compression valve (14) provides the pressure necessary to carry the waste to the sewage or sewer pipe (15). It is important to note that the intermediate compression valve (14) is installed in the pipeline itself (5) and becomes part of the pipeline through which the waste is aspirated and which is responsible for expelling the waste directly to the system sewage or sewage (15). This is the case when the valve (2) or outlet gate is opened and the debris is sucked, by means of the pressure difference that the vacuum chamber (6) produces when the vacuum pump (13) is activated. For the waste to be transported quickly through the PVC pipeline or pipe (5) to the drain pipe (15) (which goes to the sewer), there must be an element that adds sufficient force to the suction to expel said waste. The controlling unit (7) is the one that controls the intermediate compression valve (14), and as the pipeline or pipe (5) through which the suction occurs is longer, the greater the distance with the duct of sewer (15), and greater the force that the intermediate compression valve (14) must have (valve with greater compression capacity).

Finally, the waterless toilet system (100) has a series of sprinklers (not shown) that are installed along the upper inner edge of the toilet (1); and through these sprinklers a disinfectant liquid is poured which is also a fragrance, in the same way that occurs in aircraft toilets. For this there is a container (9) located behind the toilet (1) in a non-visible place and next to the controller unit (7) that controls the disposal system (100) of human waste. This disinfectant liquid is stored in an amount of 1 liter or a liter and a half and is the disinfectant and odor eliminator that can be replenished once it is finished. It is cheap and easy to prepare (a blue tablet is bought which dissolves in 20 liters of water, for sale in commerce and is supplied at the time of suction by the evacuation system (100) of human wastes without water.

The evacuation system (100) of human waste without water also offers design variants in which the system can be mounted on the wall and whenever the user needs to use it, it only pulls out the toilet and seats to evacuate. A Once the debris is finished and evacuated, the system is again pushed or retracted inwards, stored inside the wall, just like some modern washing machine models.

This is achieved by considering a vacuum pump (13) of variable size / capacity, with multiple entries, and a controller unit (7) to operate the entire human waste disposal system (100).

For a system of evacuation (100) of human waste without water that uses a small vacuum pump (13) it is simple and uses an electrical circuit of 220 volts alternating current. In case of climbing to operate the bathrooms of a shopping center or the departments of a floor, the evacuation system (100) of human waste without water, must use higher powers and consider an industrial electrical connection (three-phase) to act on a pump vacuum (13) large.

APPLICATION EXAMPLE

The vacuum pump (13) is connected to 2 or more toilets (1) at the same time. Each toilet (1) sends an electrical signal to the vacuum pump (13), which acts according to the suction demand for the disposal of the waste. For this, a pipeline or pipeline (5) is provided with intermediate compression valves (14), located at strategic points to expel waste to the drain pipe, which ends in the sewer (15). At the same time, the controller unit (7) sends a signal for the discharge of a disinfectant and aromatizer liquid a from the toilet (1) that has been used through a series of sprinklers that are distributed along the inner upper edge of said toilet (1).

The proposal considers these variants and is flexible and adaptable to the needs of the enclosure or room that requires it in a particular mode of operation.
