Abstract

The invention relates to a device that is used for the preventive and corrective maintenance of diesel tanks. The inventive device comprises a suction arm and an expulsion arm which are inserted in the tank in order to absorb the diesel and the solids created by the tank. Moreover, the expulsion arm is used to clean the inside of the tank using the pressure created by the transfer pump. The aforementioned diesel flows through a pre-filter which is disposed horizontally in order to capture the large solids and which is connected to a sensor. Said sensor is used to analyse the diesel, displaying the quantity of suspended solids contained in the tank and the humidity of said tank on a computer screen. The inventive device comprises the most advanced technology which can be used to clean tanks requiring maintenance in an effective, rapid, precise and reliable manner. Furthermore, the device is designed to ensure that tanks are maintained in good condition. More specifically, the device prevents diesel pumps in truck tractors and injectors from being damaged by the bacteria inside the tank, given that said bacteria produce the black smoke which issues from the exhaust and which is dangerous for the environment.

Description

MACHINE FOR PREVENTIVE AND CORRECTIVE MAINTENANCE OF TANKS

OF DISEL

BACKGROUND OF THE INVENTION

Today the machine for the maintenance of disel tanks is

Composed of: a 1 HP engine, a gear pump, pre-filter, a

Press filter, an exhaust valve, two hoses (one inlet and

another outlet), a relief valve and a pressure gauge that indicates the

flow pressure installed in the press.

The machine system is good, but it is not enough to clean well

the tank since only two hoses are driven: one is the

which sucks and disels and another is the one that returns it to the tank, with these

purifies the disel but the goal is not achieved, which is to maintain

I clean the tank.

It has a prefilter system; to retain all particles

older from the tank. Its manufacturing is totally

inadequate, since at the time of opening it automatically spills

the disel that contains this prefilter and the one coming from the deposit of the

relief valve, these are approximately 10 L. These 10 L. go directly to the ground and cause damage to the environment

environment and apart is totally insecure, so it has to be used

a tray the width and length of the machine so that the disel falls in

the same. Another defect that this machine has is that it counts

only with a pressure gauge which only measures the pressure

in the press and what is needed is to know how contaminated the

disel and how much solids it brings; also the float system that

brings is not suitable because at the time that relieves diesel to the press

it comes back contaminating, it also has no way to retain the

solids that fall to the float and this causes dirt to be giving

turns and there is no clarity in knowing if the solids are the tank or the

float tank.

Its tires are made of rigid material and this does not allow handling

adequate since with anything you can get stuck and prevent it

maneuver safely, and cause accidents, also has

two tubes to maneuver it and these are the ones that can cause damage to

Some part of the body being that the machine steep easily. So

like this one, there are other machines such as: one that has

a motor pump but we know that it does not have the capacity or the strength necessary to extract solids from a tank since its capacity to

transfer is approximately 50 L. per minute and does not have the

absorption and expulsion arms as these are the key to make the

service. In order to obtain a better service, the

more advanced technology for the machine, and protect it by means of the

present request

DESCRIPTION OF THE INVENTION

The characteristic details of this novel machine are shown

clearly in the following description and in the drawings that

accompany, as well as an illustration of it and following them

reference signs to indicate the parts and figures shown.

With reference to figure (No. 1), the machine is formed on its outside

by (No. 1) an aluminum structure, so that it is lighter and

be more maneuverable with (No.2) a tank on the top in

Tank shape, (No.3) The entire pipe is made of aluminum since

With this type of material we avoid corrosion and make it lighter,

(No.4) inflatable tires, with these we will get a better displacement

and it will be more maneuverable. (No.5) electrical installation, it contains a

automatic stop system in cases of current variations.

The construction can be seen in figure (No.2), being able to observe the

changes made; (No.l) suction arm in which it can be a

cylindrical, prismatic or truncated conical configuration, for the best

solid suction at the bottom of the tank, these will be equipped with

Measured according to the difficulty of the tank, they will also have certain folds that they need, being these of a material like aluminum, steel

stainless, or a flexible material. They thought about these so that they could

subtract all solids and impurities from the tank, and have control

on the tank, these are introduced and one absorbs and controls all the

tank reaching places where solids, water and more impurities do not

They can get out so easy and with these is the solution to this problem. The other

arm returns the pressure plate to detach and remove impurities

that contains the tank and with the same disel is washed and without the need of

chemical or by means of water, (No.2) reel where the

inlet hose so that it does not interfere when the machine is operated, this

Reel will be placed at the ends of the machine.

With this type of racing we avoid dragging the hoses and that

these hinder, in addition to being more aesthetic, (No.3) prefilter placed in

vertical position with a sieve, for the retention of larger particles

1 cm With this prefilter placed vertically, since the previous

horizontally it was very problematic, when uncovering the

disel fell and did not have a deposit in which to retain this disel, he thought of

a better type that is prismatic and also has a

unevenness so that all kinds of particles larger than V2 cm And apart with a drain system so that when withdrawing

said particles, the disel does not fall out of control and then we drain it and

we can work safer, plus a pressure gauge was placed to

to indicate when the prefilter is full, in addition a

Acrylic top cap to see inside this cap or

saturate paper or substances that prevent the flow of diesel (No.4)

suspended solids, humidity and density analyzer sensor

disel, is what this sensor will analyze to know the content of the

tank because in this way we will know what the tanks are

contain, (No.5) kill bacteria by means of 03, it kills the bacteria

Created in the tank.

These bacteria are the number one factor that pollutes the disel and the

tank, since it creates water and by having water we will get life and kill

bacteria is the one that will eliminate them by means 03. and thus we protect the

truck injectors and disel pumps, (No.6) pump

transfer of 2, this can vary its size because thanks to this it is

which will give us the pressure we need for the detachment of

the solids inside the tank. This is gears to get a

greater absorption force and greater safety due to its gears, (No.7) 1HP explosion proof engine. This engine has the capacity

enough to move the transfer pump, and it is also totally

closed to prevent diesel from penetrating and causing accidents,

(No.8) filter press with a circular design, with 3 inlet holes and 3

Output, consists of 10 filter plates using paper of a miera.

With this filtration system you will appreciate the amount of solids per

tank; this type of design was made to have a larger field of

filtration, (No.9) filter with cartridges; it is for the retention of solids that

They are in the press because when changing filters

these solids create the surface and are directed to this filter to prevent

go straight to the exhaust valve which returns the disel

Press content. This filtered filter weighs the relief valve

(float) to return to the press and clean and not be recycling

same solids, (No.10) relief valve (float) it returns the

accumulated clean diesel that the press tends to leak, which does not

allows the machine to saturate with disel, (No. l l) reel where the

outlet hose is rolled, using a hose from 1 to 2 of a

fully disel-resistant and durable configuration for changes

of temperature either high or low; these reels will facilitate handling of this, (No.12) output arm is the one that helps us obtain an effective

cleaning the inside of the tank, exerting a pressure by the pump

so that the disel in turn comes out under pressure, since it has a fold in the

tip, this one has adapted to the different tanks that exist to have

cleaning control and covering the walls of said tanks,

(No.13) reel for the machine's electrical cable, this one was thought to

avoid being rolled up anywhere without it having a place

specific, and that is why this reel was put on it, it is also more

Practical and less cumbersome, (No.14) control unit, can be a

laptop or a board, this is to retain all the

information of each tank that is washed and will also allow us

observe by means of graphs or another tool, the impurities that

go through the censor.
