Abstract

The present disclosure relates to a mixer device having a housing including at least first and second adjacent mixing cells ( 2, 3 ), each cell ( 2, 3 ) including a fluid inlet opening ( 21, 31 ) and a fluid outlet opening ( 22, 32 ), the inlet opening being offset from the outlet opening so that the axis of the inlet opening is parallel to the axis of the outlet opening, the outlet opening of the first cell being connected to the inlet opening of the second cell via a connecting channel.

Claims (33)

1 . A mixer device comprising:

at least one inlet port for feeding in components to be mixed, and

an outlet port for the recovery of a mixed product composed of said components,

wherein

the mixer device further comprises a housing including at least adjacent first and second mixing cells, the second cell extending over the first cell, each cell including an inlet opening and an outlet opening provided on opposite walls, the inlet opening being offset from the outlet opening such that the axis of the inlet opening is parallel to the axis of the outlet opening, the outlet opening of the first cell being connected to the inlet opening of the second cell;

wherein the mixer device further comprises:

a first tubular casing including a bottom,

a second tubular casing having an outer diameter smaller than the inner diameter of the first casing,

wherein the second casing comprises circular rings on the outer face thereof each having at least one through aperture, said rings extending radially and protruding towards the outside of the second casing, the diameter of the rings being substantially equal to the inner diameter of the first casing, and

wherein the second casing is capable of being inserted into the first casing such that the first and second casings extend coaxially, the rings defining, with the first and second casings, the mixing cells.

2 . The mixer device according to claim 1 , wherein the housing is cylindrical and has coaxial tubular outer and inner walls defining a space for receiving the mixing cells.

3 . The mixer device according to claim 2 , wherein each mixing cell has a cylindrical shape and extends between the outer and inner walls of the housing.

4 . The mixer device according to claim 3 , wherein at least one of the mixing cells comprises diametrically opposed fluid inlet and outlet openings.

5 . The mixer device according to claim 1 , further comprising a plurality of superimposed mixing cells, the superimposed mixing cells being arranged so that the outlet of each upper cell extends in front of the inlet of the lower cell on which said each upper cell is placed.

6 . The mixer device according to claim 5 , wherein the plurality of mixing cells comprises:

an initial cell wherein the components to be mixed are fed, and

a final cell through which the mixed product is discharged,

the outer wall of the housing comprising a bottom for recovering the mixed product discharged from the final cell.

7 . The mixer device according to claim 6 , wherein the inner wall of the housing defines a discharge channel for the mixed product, the mixer device comprising a suction nozzle intended for being arranged in the discharge channel for the extraction of the mixed product.

8 . The mixer device according to claim 1 , wherein the housing extends longitudinally, the inlet and outlet ports extending at a same end of the housing.

9 . The mixer device according to claim 1 , wherein at least one of the cells comprises an element forming an obstacle.

10 . The mixer device according to claim 9 , wherein the element forming an obstacle is a ball on the flow path of the components.

11 . A mixer device comprising:

at least one inlet port for feeding in components to be mixed, and

an outlet port for the recovery of a mixed product composed of said components,

wherein the mixer device further comprises a housing including at least adjacent first and second mixing cells, the second cell extending over the first cell, each cell including an inlet opening and an outlet opening provided on opposite walls, the inlet opening being offset from the outlet opening such that the axis of the inlet opening is parallel to the axis of the outlet opening, the outlet opening of the first cell being connected to the inlet opening of the second cell;

wherein the housing comprises an inner wall and an outer wall; and

wherein the inner wall of the housing defines a discharge channel for the mixed product, the mixer device comprising a suction nozzle intended for being arranged in the discharge channel for the extraction of the mixed product.

12 . A mixer device comprising:

at least one inlet port for feeding in components to be mixed, and

an outlet port for the recovery of a mixed product composed of said components,

wherein the mixer device further comprises a housing including at least adjacent first and second mixing cells, the second cell extending over the first cell, each cell including an inlet opening and an outlet opening provided on opposite walls, the inlet opening being offset from the outlet opening such that the axis of the inlet opening is parallel to the axis of the outlet opening, the outlet opening of the first cell being connected to the inlet opening of the second cell, and

wherein the housing extends longitudinally, the inlet and outlet ports extending at a same end of the housing.
