Description

"WATER AND SOLID SEPARATOR APPARATUS CONTAINING DIESEL, HIGH FLOW CAPACITY, IMPROVED".

Background of the invention.

It is known that the quality and refining of the fuels used in Mexico by motor vehicles is not the best in the world. Originating premature wear in the motor vehicle and consequently, in the economic aspect. This is maximized if fuel consumption is required by large engines such as ship engines, boilers, etc. The fuels obtained in our country are of poor quality due to their high content of sulfur, paraffin and sulfuric acid, elements that damage the life of the internal combustion engines of motor vehicles. To the above, the dust or garbage that is introduced into the storage tank during the filling operation is added. In addition, the metallic nature of the storage tanks together with the water condensation layer that commonly forms on the upper and inner surface of the tank, gives rise to the oxides that, when mixed with diesel, further deplete the combustion capacity.

There is currently a refiner conventionally specified in Mexican patent no. 155717, this refiner is aimed at separating the impurities contained in the fuel, diesel, due to the generation of a force equivalent to centrifugation, where the diesel is introduced through a hole and exits through another already refined. As you might think, this refining apparatus protected by Mexican patent no. 155717, is not designed to receive diesel in high flow, coming from machines that require high consumption, such as naval machinery, boilers, etc. What causes to provide a diesel fuel with a high percentage of impurities, which the primary filter can not retain, causing the rapid replacement of this, in addition to providing an unpurified fuel, with a high degree of impurity concentration, in addition to a once the water or solids have been separated from diesel and they reach a certain level within said apparatus can cause problems due to not being drained (the separating apparatus) in time. With the purpose of eliminating these and other inconveniences, the present Water and Solids Separating Apparatus that Contains Diesel, High Flow Capacity, Improved, which is intended to be protected by means of the present application, was considered, since it is a apparatus that decreases in its interior the inlet pressure of the fuel in it, causing the fuel to separate from the impurities by the precipitation principle, depositing them in the lower part of the apparatus, and which also incorporates a sensor that detects when the level of impurities and water reaches its maximum, supplying diesel fuel free of water and impurities in. 99% at the top, ready for use, which can be preheated by a resistor built into the bottom.

Object of the invention.

The object of the invention is to provide a new type of Water and Solids Separator Apparatus Containing Diesel, High Flow Capacity, Improved, whose main feature is that it allows water and impurities to be separated from diesel fuel even if the needs of consumption are very high,. and in a more efficient way, as the pressure in the inlet flow of diesel fuel decreases, for the separation of impurities (water, oxides, sulfur, etc.), being placed between the storage tank and the filter of the vehicle or machine , so that the diesel received in the engine injection system, via the primary filter, is of maximum purity, also incorporating a sensor that indicates when the level of impurities are these water or solids reached the maximum to be drained by the valve placed on the bottom cover, also incorporating a copy with a pressure plug to purge the air when the tank is empty, and will be filled in addition to providing precautionary It is placed on the diesel by means of a resistor placed in the threaded tube incorporated in the lower cover of the device.

Preferred embodiment of the invention (or best known method for carrying out the invention.

With reference to said figures, the Water and Solids Separator Apparatus Containing the Diesel, High Flow Capacity, Improved, (figs. 1 and 2) is formed by a metal cylinder made by mechanical means of formation, such as bending, extruded, stamping, etc., depending on the process used for its realization, welding is used to join it, being able to be welded with or without metal, autogenous or electrical, manual or automatic, externally to the cylinder a threaded tube is incorporated (1.2) to connect the hose (not illustrated) that supplies the fuel that comes from the storage tank, this tube (1 _* 2) is in correspondence with the inlet hole (3.3) of the rectangular cubic body (3.1) placed in the inside the cylinder (figs. 3 and 4), this hole (3.3) has the same dimension as the inside diameter (2.3) of the fuel inlet pipe (1.2), the rectangular cubic body (3.1) placed inside, has a length (figs. 3 and 4) almost the same as the dividing plate (3.10) placed diametrically inside (fig. 4), the rectangular cubic body (3.1) incorporates in the face that corresponds to the inside of the cylinder and in the lower part a hole of greater diameter (3.2) than the entrance hole (3.3), and it is through the hole of greater diameter (3.2) where the diesel fuel inside the cylinder is released once it enters the apparatus, in the same way it it provides in the lower part an opening as a result of the angle of the lower plate (8.1) which is auxiliary in the dissipation of the pressure in the Diesel fuel inlet flow, inside the cylinder a plate (3.10) is incorporated whose measure in width corresponds to the inner diameter of the cylinder and longitudinally its measurement is relative to the size of the cylinder without its covers (figs. 3 and 4) , this plate (3.10) internally divides the cylinder into two equal semicircles, and allows the turbulence created by the passage of the fuel not to affect the already purified fuel, in addition this plate (3.10) supports the breakwater plates (figs. 3 , 4, 5, 6 and ^j 7, 3.4, -3.5, 3.6, 3.7, 3.8 and 3.9), each 'rσmpeoia plate has a different shape which allows the fuel inlet pressure of the water separating apparatus and solids that can be between 40 and 150 or more gallons per minute, be dramatically decreased, this is due to its strategic placement and with an approximate angle of 45s with breakwaters can vary according to the needs in each purifying device and depend Of the amount of fuel to be purified, these breakwaters (3.4, 3.5, 3.6, 3.7, 3.8 and 3.9) are placed inside the cylinder, where the square-shaped breakwater (3.4) is at the same height as the hole outlet (3.2) of the rectangular cubic body, attached to the inner wall of the cylinder by means of welding, said breakwater is placed vertically, just above this breakwater and in correspondence with the semicircle where the rectangular cubic body is located is placed Another breakwater (3.5) that has a flat face to fit perfectly with the internal dividing plate (3.10), this breakwater (3.5) has a semicircular shape with triangular cuts and following the shape of the rectangular cubic body (fig. 5) and is installed with an approximate angle of 452, in the semicircle that corresponds to the exit hole (1.3) of the purified fuel, it locates another breakwater (3.6) that fits perfectly by welding and that has triangular shaped cuts placed at an angle of approximately 455, likewise, in that same sector a Breakwater (3.7) that has triangular cuts, located at an approximate angle of 22 or 32, also, optionally and according to the purification needs according to the inlet pressure of the diesel fuel in the purifying apparatus, they can incorporate more breakwaters (3.8 and 3.9), both in the sector corresponding to the rectangular cubic body and in the sector corresponding to the exit hole of the diesel fuel already purified (illustrated in figs. 5 and 6), the breakwaters (3.4, 3.5 , 3.6, 3.7, 3.8 and 3.9) have been incorporated in order to prevent impurities from entering the diesel fuel outlet due to the pressure of the device's fuel flow, without this meaning that the separator does not perform properly its function of separating impurities from diesel fuel, in addition this device has two covers, one upper (2.1) and one lower (2.2) where two plugs (1.5 and 1.6) have been incorporated that- it serves to purge the indoor air of the purifying apparatus and a purge valve of the impurities deposited in the lower part of the apparatus, where the plug incorporated in the upper cover (1.6) works to remove the air from the apparatus, and the purge valve bottom (1.5) serves to remove the impurities deposited on the inner bottom surface of the separator apparatus, to provide the primary filter with a fuel with a purification of between 98 and 99%, leaving the Separator of Water and Solids that Contains Diesel , High Flow Capacity, Improved, through the outlet pipe (1.3) so that it passes to the totally pure engine, in addition to the body of the Water and Solid Separator Apparatus that Contains the Diesel, High Flow Capacity, Improved, a copy (1.8) has been incorporated in 1/8 ^"size that functions as an input for a (commercial) sensor that indicates when the device must be purged when the level of impurities has reached its maximum as allowed, preventing impurities from entering the engine, and damaging it, and a copy that works as a cover has also been incorporated into the upper cover (2.1). Exhaust valve (1.7) for the air that the device contains when it does not have diesel and is to be connected to the combustion system, likewise incorporates an inlet (1.4) in the form of a threaded tube, in the lower cover (2.2) to place the device that preheats diesel fuel, to send a preheated fuel to the engine. The principle under which the present Water and Solid Separator Apparatus Contains Diesel, High Flow Capacity, Improved, acts is the principle of separation of elements due to their specific weight, in the case of being elements of different specific weight , such is the case of diesel fuel, whose specific weight is less than 1, which is of lower density than water whose specific weight is 1, so diesel fuel is kept separate from water and impurities at the top of the purifying apparatus, leaving the impurities that are of a specific weight equal to or greater than 1 and the water on the lower surface inside the Separating Apparatus.

The diesel fuel supplied from the storage tank enters the purifying apparatus (figs. 1 and 2) with a pressure between 40 and 150 gallons per minute, entering the rectangular cubic body, generating an effect similar to centrifugation, causing The separation of the elements, due to the pressure of the inlet flow, if the Water and Solid Separator Apparatus that Contains the Diesel, High Flow Capacity, Improved, will not have the breakwater plates, the fuel flow required by the Internal combustion engine would be such that the purified fuel, when sucked by the outlet tube would be re-mixed with the separated impurities, so the diesel fuel already purified exits through the tube provided for that action, towards the primary filter that supplies finally the fully purified fuel to the engine.

According to field tests carried out with the Water and Solids Separator Apparatus Containing Diesel, High Capacity Flow, Improved, it can be affirmed that the retention of impurities such as water, sulfuric acid, sulfur, paraffin, oxides from storage tanks and other impurities that the fuel could have before entering the purifying apparatus, are eliminated in a percentage of between 98 and 99%. For all the above, it can be affirmed that these characteristics of separation of materials, have not been achieved by any other similar device and brings together the characteristics of separation in a percentage of 98 to 99% in fuel flows with inlet pressures ranging from 40 to 150 gallons per minute or more, in addition to providing a sensor that indicates when the impurities separated from the diesel have reached their maximum limit and must be purged, in addition to incorporating a copy for air purge valve and a input for the device that preheats the fuel, thus obtaining a preheated diesel fuel and with an impurity-free percentage of between 98 and 99%.

Another feature of this Water and Solid Separator Apparatus that Contains Diesel, High Flow Capacity, Enhanced, is that it can also be used to separate other combustible materials such as gasoline.
