Continuous filtration device

A continuous filtration device comprising:

• barrel-shaped filter cells, each presenting an opening which is placed upwards during filtration and which is covered by a filtering layer, these cells being arranged in a carousel around a vertical axis of rotation and each presenting a horizontal axis of tilt which intersects the axis of rotation of the carousel,
• a lever connected in a fixed way to each filter cell, so as to intersect their axis of tilt at a tilting point,
• follower elements, carried by the lever and placed on it on either side of the tilting point,
• at least one stationary guiding element for each of the follower elements of the lever of a cell, these guiding elements being reciprocally arranged in a carousel area so as to achieve a tilting of each cell inside this area about its axis of tilt,
• at least one housing provided in the first of these guiding elements for the corresponding follower element, this housing being placed so as to allow a turning of the lever around the follower element in position in this housing,
• at least one loading area which is provided on a second guiding element and on which its corresponding follower element acts when the follower element corresponding to the first guiding element respectively leaves its housing or enters the latter, and
• means for rotationally driving the filter cells around the aforesaid axis of rotation,
• a first additional lever connected in a fixed way to each filter cell, on or near to their axis of tilt,
• a first mobile stop, and
• an elastic element connecting the first stop to a fixed support and acting on the first stop in a first direction,
• said first additional lever cooperating with the first stop by acting on it in directions always approximately opposite to the aforesaid first direction, while the follower element corresponding to the second guiding element acts on the aforesaid corresponding loading area.
