The present invention refers to a pneumatic device particularly used to clean magnetic separators blocks avoiding incrustations in these blocks' gaps.

Background of the invention

Despite the use of methods to avoid the contamination of the blocks of magnetic separators, more precisely the blocks' gaps, such contamination still occur due to factors inherent to the process and, as a result, the gaps are filled with incrustations.

Actually, the gaps of the magnetic separators blocks are cleaned in a very repetitive way, where the operator needs to apply multiple strokes of a hammer on a clean spatula to clean the incrustation in a block's gap. Each block has 80 gaps. Each magnetic separators has 27 blocks in the upper magnetic rotor and more than 27 in the bottom rotor, therefore, it takes a lot of time and hammer blows per gap to clean a magnetic separator.

In this sense, it is necessary to make available different kinds of process and tools for cleaning these gaps.

Summary of the invention

Then, in order to overcome this problem the present invention provides a pneumatic device comprising a main body in which a spatula is fixed. The main body comprises the pneumatic system that pulses the spatula within the gap removing the incrustations.

Description of preferred embodiments

The present invention relates to a device 10 to clean blocks of magnetic separators, more precisely the blocks' gaps

As illustrated by figures 1 to 4, this device 10 comprises a main body 1 provided with a pneumatic system and a spatula 2 associated to this main body 1 through a fastener element 3. The spatula 2 comprises a first edge 21 that contacts the blocks of magnetic separators to clean its gaps. This spatula 2 also comprises a second edge 22 that is associated to a cavity 1 1 in the main body 1. Specifically, the second edge 22 of the spatula 2 is positioned inside the cavity 1 1 of the main body 1.

According to figure 4, the fastener element 3 is concentrically attached to the spatula 2 and the main body 1 , providing the joint of the second edge 22 of the spatula 2 within the main body 1.

The main body 1 comprises a pneumatic system that pulses the spatula 2 into linear movement in contact to the block. The spatula 2 is positioned inside a block's gap of a magnetic separator. With the pulse impact provided by the pneumatic system, the spatula 2 can remove the incrustations found in this gap.

This device 10 replaces the effort made by the operators by the pneumatic system.

Another advantage is that the device allows the cleaning of the gap's even with fine material deposited in the blocks.
