    DESCRIPTION

    Tissue oil removal procedure.

    The present invention discloses a tissue washing process. More specifically, the present invention discloses a method of removing oil from fabrics and the like in a simple, efficient manner and with a very good washing effect providing sensitive characteristics of novelty and inventive activity.

    Currently, tissue oil washing processes are carried out in which depletion is acted upon, that is, the fabric is advancing through different rollers in which said tissue is partially submerged in a tank containing a washing fluid. As is known, the washing process is comprised of a tank where the tissue is bathed through a roller system, then going through a draining phase. Normally, said bath is at rest, that is, there is no movement of the fluid. Generally, the washing process 15 is formed by a single main tank comprising a plurality of rollers.

    According to known technique, most current depletion washing procedures have a rest bath in a tank where the tissue is submerged in said bath. The washing of the tissue is not very effective, and the quality of the tissue after washing is not good. A problem with using a single tank is that different concentrations of detergent cannot be used, that is, different washing liquids at different washing stages. According to known technique, there are devices that generate bubbles to stir the bath in order to improve the quality of washing and accelerate the process of removing oil from tissues. However, there is still a need for more efficient washing processes for the removal of oil in tissues.

    The applicant has performed tests with different speeds of rotation of the rollers, tissue tensions, number of rollers, dimensions of the tank, types of detergents and concentrations of detergent in water. However, although the control of the aforementioned 30 parameters improves the efficiency of the washing process, the results are expected and do not provide substantial improvements.

    An object of the present invention is to improve the process of removing oil from fabrics, obtaining fabrics with less oil in them after the washing operation in a more effective way and with higher quality than is known in the state of the art. current.

    The method of removing oil from tissues object of the present invention comprises a first phase in which a washing liquid contained in a first tank is forced to pass through an object tissue from which the oil is to be removed in a transverse direction. to the fabric, from an inlet face in the washing liquid to the opposite side of the fabric, which is the opposite face of the washing liquid, during the movement of the tissue through the washing liquid contained in the tank when a flow of washing liquid

    Preferably, the present invention achieves said flow of transverse washing liquid by submerged suction. Said submerged suction is created by the aspiration of a washing liquid through the tissue by means of tubular elements of forced aspiration as a result of the suction or aspiration of at least one aspiration pump. That is to say, the washing liquid contained in a tank is forced to pass through the object tissue when a flow of washing liquid is created transverse to the longitudinally displaced tissue.

    Preferably, the fabric is applied tangently on grids of the aspiration tubes, in which said aspiration tubes are connected to a pump. So, the flow of
    Washing liquid transverse to the tissue is generated by the aspiration of the washing liquid through an aspirating pump or a plurality of aspirating pumps that sucks the washing liquid through at least one tube from the tissue outlet face. Preferably, the suction of the washing liquid is carried out by means of two suction tubes for each tank in which each suction tube has a grid. 5

    Preferably, the washing liquid is a mixture comprising water and detergent.

    The process may comprise a recirculation of the washing liquid. This can be achieved by a feedback system of washing liquid in which said washing liquid 10 returns back to a tank allowing the circuit to close. Preferably, the process comprises a recirculation of the first washing liquid and / or the second washing liquid in the first and / or in the second phase. More preferably, the recirculated liquid is introduced into the respective first or second tank at a point below the level of the respective washing liquid. In addition, the tissue oil removal apparatus may have an intermediate tank and two drains one for each tank.

    The present invention also provides for the two-phase embodiment, in which each phase is carried out in a different tank and in suction submerged with a different mixture of water and detergent in each tank. twenty

    The process object of the present invention may comprise a second phase in which a second washing liquid contained in a second tank is forced to pass through an object tissue from which the oil is to be removed in a transverse direction to the fabric, from a inlet face in the second washing liquid to the opposite side of the fabric, which is the opposite side of the second washing liquid, during the movement of the tissue through the second washing liquid contained in the second tank.

    Thus, the tissue oil removal process may comprise two phases: first phase and second phase. Preferably, the process is carried out in two independent tanks 30, one for each phase, which can be configured to control the concentration of detergent in water, the suction of the bath and the rotation speed of the cylinders of the tanks. In particular, the concentration of detergent and water has to be appropriate for the detergent to emulsify the oil. In the second phase, said detergent is introduced into the second tank with a concentration that may be different from the first phase, that is, the first washing liquid in the first phase and the second washing liquid in the second phase may be different. Consequently, the percentage of water and detergent of the first washing liquid and the second washing liquid may be different, the second washing liquid having a lower detergent concentration than the first washing liquid. Also, the recirculation of water in the second phase, that is, in the second tank, is usually greater. In this way, the recirculation of water allows the tanks to be fed with clean water and the dirty bath is renewed by overflow. The dirty bath refers to the solution of washing liquid and removed oil arranged in a tank. In the second phase, more water recirculation is needed to clarify the tissue, in which said water recirculation can be regulated with a variator. Depending on the fabric, the optimum degree of water recirculation can be adjusted.

    In the present invention, the flow of washing liquid transverse to the tissue refers to the direction of the flow of said liquid being perpendicular to the object tissue, that is, perpendicular to the displacement of the tissue. fifty

    Water recirculation refers to the concept of driving water circulation back into the same circuit. Recirculation can be partial or total. Partial recirculation refers to the washing liquid that is reintroduced to the circuit that can be formed by a
    combination of clean water and dirty water. Also, only clean water can be used in the partial recirculation operation, the respective tank or both being fed with clean water. Clean water refers to water that has not been used by the tissue oil removal machine. Dirty water refers to the washing liquid that has been used by the tissue oil removal machine. Dirty bath refers to the solution of washing liquid and removed oil arranged in a tank. Total recirculation refers to the water that is reintroduced to the circuit that consists only of dirty water. Additionally, dirty water can be treated by a purification operation.

    The fabric washing process can be performed in a plurality of tanks, preferably resulting in two tanks. The percentage of water and detergent in the washing liquid can be different in each tank. Preferably, the detergent used is a detergent that emulsifies the oil. More preferably, the solution of water and detergent in the second cell has a lower detergent concentration than in the first cell. In a particularly preferred embodiment, the second washing liquid does not comprise detergent and may be, for example, water.

    Preferably, the suction of the washing liquid is carried out by means of two suction tubes for each tank in which each suction tube has a grid.
     twenty
    Next, preferred exemplary embodiments of the present invention will be described in detail in reference to the accompanying drawings. It should be noted that known functions or configurations will not be described in detail or will be omitted so as not to disclose an unnecessarily ambiguous invention.
     25
    The foregoing and other features and advantages of the invention will be better understood through the following illustrations and the detailed non-limiting description of preferred embodiments thereof, with reference to the drawings in question, in which:

    Figure 1 schematically shows the process of removing oil from tissues. 30

    Figure 2 schematically shows two tanks with their respective solutions for the removal of oil from tissues.

    The tissue oil removal process of the example is comprised of two phases: a first phase -100- and a second phase -200-, in which each phase is carried out in a vat and in submerged suction.

    The first phase -100- of the process comprises a first tank -1- in which a fabric -3- is guided through a roller system -4-. The first tank -1- is filled with a first washing liquid to which the tissue is subjected. The first washing liquid, in turn, is formed by water and detergent. The first tank -1- receives a first washing liquid, presenting a communication overflow with a lower conduit -5- destined for the conduction of the bath towards the outside. In the example of the present invention,
    tubular elements such as elements -6- and -7- that are connected to a suction pump that sucks the bath located in the first Cuba -1- through front suction grilles -8- and -9-, doing so then pass through a conduit back to the bathroom, that is, operating in a closed circuit. The front suction grilles -8- and -9- receive the tissue -3- that pass in friction thereon, so that given the aspiration of the first washing liquid by the action of an aspiration pump, a forced passage occurs 50 of the first wash liquid through the tissue.

    The second phase -200- of the process begins at the end of the first phase -100- and comprises a second tank -2- in which said fabric -3- is passed through a roller system -10-
    similar or equal to roller system -4- located in the first tank -1-. The second tank -2- is filled with a second washing liquid which may comprise a different solution than the first tank -1-. The washing liquid, in turn, can be formed by water and detergent in a different percentage than the first washing liquid of the first tank -1-. The second tank -2- receives a bath of a second washing liquid, presenting a communication overflow 5 with a lower conduit -11- destined for the conduction of the bath towards the outside. In the embodiment of the present invention, tubular elements such as elements -12- and -13- are available which are connected to a suction pump that sucks the bath located in the second tank -2- through front suction grilles -14- and -15-, then passing it through a conduit back to the bathroom, that is, 10 operating in a closed circuit. The front suction grilles -14- and -15- receive the tissue -3- that pass in friction thereon, so that given the aspiration of the second washing liquid by the action of an aspiration pump, a forced passage occurs of the liquid through tissue -3-.
