Abstract

A device for separating waste includes a tank having a closed internal chamber, the device being provided with an inlet opening and an outlet opening that can be connected to a suction system. The internal chamber of the tank is provided with a magnetic filter making it possible to attract and retain ferromagnetic waste likely to be entrained by the suction system into the tank, with a grating placed between the filter and the base of the tank, with a fluid discharge system at the level of its base. The device which is intended to be connected to a suction system makes it possible to retain and recover, sorted, the waste sucked in by said system and prevent the latter from polluting the pipelines thereof until they are blocked.

First claim

The invention claimed is:

1. A device for separating waste, the device comprising:
a tank having a closed internal chamber having an opening with a perimeter located in a first horizontal plane,
wherein the device is provided with an inlet opening and an outlet opening that can be connected to a suction system,
wherein the internal chamber of the tank is provided
with a magnetic filter making it possible to attract and retain ferromagnetic waste likely to be entrained by the suction system into the tank;
with a grating placed between the filter and the base of the tank; and
with a fluid discharge system at the level of a base of the internal chamber, and

wherein the inlet opening and the outlet opening are located on a same side of the first horizontal plane and the magnetic filter is arranged on other side of the first horizontal plane.

2. The waste separation device as claimed in claim 1 , wherein the magnetic filter comprises at least one bar passing at least partially through the internal chamber of the tank.

3. The waste separation device as claimed in claim 2 , wherein the magnetic filter comprises several mutually parallel bars passing through one and the same second horizontal plane and passing at least partially through the internal chamber of the tank, wherein the second horizontal plane is parallel to the first horizontal plane.

4. The waste separation device as claimed in claim 3 , wherein the magnetic filter comprises a comb of bars made of a single piece.

5. The waste separation device as claimed in claim 4 , wherein the comb comprises a comb of magnetic cores and a comb of sheaths, each core of the comb being inserted respectively into each sheath of the comb.

6. The waste separation device as claimed in claim 3 , wherein the grating is arranged below the second horizontal plane formed by the bars.

7. The waste separation device as claimed in claim 1 , wherein the base is entirely inclined along a third plane such that a fluid resting on the base can flow toward said discharge system, wherein the third plane is not parallel to the first horizontal plane.

8. The waste separation device as claimed in claim 1 , wherein the base is provided with a discharge orifice, the orifice being associated with a cock fixed to the outer face of the tank.

9. The waste separation device as claimed in claim 1 , wherein the tank comprises a container and a cover.

10. The waste separation device as claimed in claim 9 , wherein the cover has the inlet opening and the outlet opening to which, respectively, two pipes of a pipeline network of the suction system are configured to be connected.
