DESCRIPTION

AUTOMATIC LIFTING SYSTEM FOR LIQUIDS AND SOLIDS A

BULK FOR INDUSTRIAL PROCESSES

OBJECT OF THE INVENTION

The present invention refers to a system that uses the mechanical advantages offered by multiple pulley systems (factorial, exponential, differential, etc.) to lift loads with substantial energy savings.

The motor used to operate this system is located in such a way that it can move two or four liquid / solid buckets at the same time; while two load the other two unload, while two rise the other two descend, saving energy by only needing the energy necessary to raise the weight of its content, and on the other hand saving time since the time of a maneuver is reduced by half as a full charge and discharge occurs.

The industrial application of this invention is found within the systems for transporting and moving loads of liquids and solids in bulk, and more specifically automatic systems for lifting liquids and solids for industrial processes.

An example of application would be to lift water from one tank to another located higher, between which one or more hydraulic turbines have been installed, depending on the height and flow necessary to feed the turbines, the number of lifting units can be installed necessary to raise the same turbinated water back to the upper tank with a notable energy saving, which would be several times less than the energy produced by the turbines, so that a percentage of that energy can be used for consumption. Given the wide variety of pulley systems and the possible combinations, none are specifically named.

BACKGROUND OF THE INVENTION

Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related thereto.

Thus, document ES2379258A1 refers to a system for taking advantage of part of the energy potential of a water current by means of a hydraulic wheel, being applicable in a flow or current of water belonging, for example, to a body of sea water, a river or even created artificially by man, that in correspondence to the water current, a hydraulic wheel is arranged, which captures part of its flow, using the kinetic energy that it contributes to make it rotate, transmitting its force by extending its axis, to a hydraulic, impeller or suction pump, or pneumatic, in its compression or depression functions, depending on its application to carry out a job. The aforementioned document refers to a system for taking advantage of part of the energy potential of a water current by means of a hydraulic wheel, while the main invention describes a system for raising liquid and solid levels to higher levels for industrial processes.

ES2274679A1 describes a support or column that supports a mechanical structure equipped with an upper shaft with two toothed wheels and a lower shaft with two more that with two chains (Gall Type) engaged in the upper and lower wheels, establish two synchronized closed circuits. These chains have regularly spaced rotating supports that hold the axes of horizontal blades that, due to the action of the wind or water, move vertically around the entire circuit as a kind of continuous blind that will take advantage of by turning the axles of the wheels. to move an electric generator, pump etc. The wind or water acts perpendicularly on the general frontal plane of the blades, and the horizontal pressure on the blades at a suitable angle will change to energetic vertical pressure. In the back plane the inclination of the blades is changed. In this case, a mechanical structure support is described with upper and lower shafts connected by sprockets and chain to move a generator electrical, forming a totally different system from the one proposed by the main invention.

Document ES2021235A6 proposes a system to produce energy taking advantage of the maritime waves, characterized in that a set formed by two elongated rigid structures arranged at an angle is used, with the set supported on two end floats and a central one to which the referred structures are joined in articulation , each one of said elongated structures comprising two or more series of opportunely related mechanisms, which are capable of being actuated by the action of the marine waves, to produce a rotary movement that allows to operate one or more generators with each series; the aforementioned structural assembly being intended to remain floating on sea water, simply held by a retention tie from its front vertex. The aforementioned invention deals with a system for producing energy by taking advantage of the sea waves, however the main invention describes a system for raising liquid and solid levels to higher levels for industrial processes.

Document ES8202892A1 refers to harnessing wave energy using displacements caused in a float. Various mechanisms are described that take advantage of the movement of the float in one direction that prevent the effect achieved from being nullified when the float moves in the opposite direction. These mechanisms consist mainly of maintaining the float displacement in a vertical direction and valves or ratchets that prevent the action from canceling the reaction. the valves are used to lift the seawater through pipes and the ratchets to cause the rotation of shafts in one direction only. Like the previous document, it refers to a system for harnessing wave energy, so it is again quite different than the proposal of the main invention.

ES0167982A1 describes a hydromechanical system that determines the continuous movement by the arrangement of an upper water tank leading the entire system from the bottom of which is a pipe that leads the water to a loading tank with the special installation of a shutter gate mechanism from which it escapes cascading water and acts on a turbine or hydraulic wheel to which it prints intense revolutions. Unlike the main invention, the system described in said document proposes a set of upper tank and lower turbine to print energy and make it rotate by means of shutter gates.

Conclusions: As can be seen from the research carried out, none of the documents found solves the problems posed as the proposed invention does.

DESCRIPTION OF THE INVENTION

The automatic system for lifting liquids and bulk solids for industrial processes object of the present invention is constituted from a traction element or motor with speed control (or speed variator), brake, a RPM reducer between the axis from the motor and the drum to lift 2 or 4 buckets provided with guides to slide in vertical movement and a side hatch to be able to automatically load and unload their contents continuously.

The system composed of each group of traction element and set of pulleys is double, in such a way that the same cable or belt used to raise or lower a bucket continues through a second set of pulleys symmetrical with another bucket, one being in the position highest while the other is in the lowest position and vice versa.

The buckets in turn are encased in a system of vertical guides to control their movement avoiding twists, overturns or unbalances during their movement. In addition, each bucket has a control system for filling / emptying its contents, consisting of a gate, closing float, and a mechanical device for opening and rearming the gate.

As the system is installed in an aqueous medium, the materials to be used are taken into account to face and resist the effects of corrosion caused by the liquids / substances to be raised.

Likewise, the tray guide system must offer the least possible resistance, either with bearings or with suitable materials.
