Description

Device for separating heterogeneous mixtures of materials according to their densities with respect to that of a fluid.

Object of the invention

The present invention relates to a device  to separate heterogeneous mixtures of materials according to their densities with respect to that of a fluid.

Background of the invention

Currently some waste materials, such as debris and the like, they have no use and they deposited directly in the landfill, with the consequent expenses.

In the case of debris, consisting of a heterogeneous mixture of rubble, wood, plastics and others impurities, once clean, that is, these impurities removed, it would be usable as raw material to make zahorra is in bases and subbases of roads or highways, or in the hearths of any kind.

However, this use is not feasible, since precisely the existence of impurities would compromise the stability and consistency of the base or subbase.

This problem is remedied by use of the device of the invention.

Description of the invention

The device of the invention serves a way optimal for the separation of mixed materials heterogeneously according to its densities with respect to that of a fluid, cooperating also to avoid dust removal, and it is special utility to clean debris from impurities and get a subsequent use.

According to the invention, the device is constituted by a tank capable of being filled with the fluid of reference density, ideally water.

In order to change or replace this fluid, or directly to empty the tank for cleaning, it they have filling and emptying ducts, which obviously incorporate flow cutting elements.

The tank incorporates an area, preferably centered, where the desired mixture of materials is poured pull apart. Ideally, the pouring is done through a hopper, thereby reducing lifting and dispersion of dust.

When density materials fall into the fluid higher than that of the fluid decant, while lower density float, being extracted to differentiated areas by paths motorized conveyor belts.

The tape that collects the decanters runs through the bottom of the tank collecting these materials, while the tape that collects the floats receives cooperation from some media that push these materials towards it, and that may consist in mechanical, blown, or any other public domain and that serves this purpose.

The dust that may remain in suspension, and that decant more slowly, it can deposit over time at the bottom from the tank, so it will require cleaning and periodic removal of these remains, for which it is provided with a door recordable

Brief description of the drawings

Figure 1 shows schematic side view of the device of the invention.

Description of a practical embodiment of the invention

The device 1 of the invention is constituted  by a tank 2 refillable with a fluid 3, preferably water, whose density will serve to effect flotation separation and decanting a mixture of debris and impurities of size of grain between 8 and 200 mm, incorporating the tank one or more filling and emptying conduits with the corresponding keys cut, not represented.

The tank incorporates a central post 4 for a hopper 5 inlet of the rubble mixture, in whose open mouth it can fall from, for example, a conveyor belt, not represented.

Inside the tank there are paths 6.7 motorized conveyor belts, which take out respectively the materials floated on one side (wood, plastics) and opted for the other (washed rubble), towards differentiated areas 8.9, where they can be collected separately.

To cooperate in the collection of materials floats a motorized roller 10 is provided in the tank and equipped with 11 radial blades, preferably perforated, that beat the surface of the fluid in the proper direction to drive these materials floated to the corresponding tape 6.

On the other hand, the decanted materials are collected directly on the corresponding tape, since this It also runs along the bottom of the tank.

The tank finally incorporates a side door  practicable, not represented, for registration and cleaning of the fund of dust or other slower decanting materials.

Describe sufficiently the nature of the invention, as well as how to perform it in practice, should be noted that the provisions indicated above and represented in the attached drawings are susceptible to modifications of detail as long as they do not alter the principle fundamental.

Claims (3)
