    Along the inlet pipe (W) 4, the suspension is fed to a device containing two transporting nets (TS), which are angled at an angle, to deposit the suspension. Between the grids there is a vertically wedge-shaped displacing body (CW) 2. In the upper part of CW 2, a recess 5 is made on the sides 6. The beveled portions of the beads 6 are directed toward the vehicle. The location of the outlet 9 PP 4 below the top edge of the sides 6 eliminates the formation of bubbles in the suspension. To reduce turbulence, the internal diameter of the PP 4 increases in steps to the outlet 9 and communicates with a horizontal tubular collector 10 located inside the CW 2. To regulate the flow of suspension to the vehicle, the valves are vertically relocated above the sides 6, Vacuum boxes mounted along the vehicle , serve to form tobacco particle films on them. The suspension that has passed through the first vacuum duct is returned to repeated filtration through a 2-groove made at the lower end of the KWT and communicated with an additional collector 12. 6 Cp f-ly, 4 ill.

    The invention relates to the tobacco industry and can be used in the recovery of a tobacco film from an aqueous suspension of finely ground tobacco waste particles.
    The purpose of the invention is to improve the quality of the obtained film by preventing its separation.
    FIG. 1 shows a device for producing a reconstituted tobacco double layer film, longitudinal section; in fig. 2 - the upper part of the device during the supply of material, increased; in fig. 3 shows an embodiment of the displacement body with an additional collector, a plan view; Fig, 4 - the same, side view.
    The device has two angularly movable transporting grids 1 for sedimentation of the suspension, a wedge-shaped displacement body 2 vertically arranged between them, vacuum boxes 3 mounted under the grids 1 and a suspension nozzle 4 in the upper part of the displacing body 2 suspensions limited by the beads 6 with horizontal upper edges 7. It is preferable to implement the device, in which the beads 6 of the recess 5 have beveled sections 8 directed outwards towards the transporting network 1.
    It is advisable to place the outlet 9 of the supply pipe 4 below the upper edge of the beads 6.
    The inlet pipe 4 may be in communication with a horizontal tubular manifold 10 located inside the displacement body 2. In addition, the inlet pipe 4 may be made with stepwise increasing: internal diameter to the outlet 9. It is advisable. Also to provide the device with flaps 11 installed with the possibility of moving in the vertical plane above the sides of the recess 5. It is possible to make the n -1high end of the displacing body 2 with a groove communicated with the additional collector 12.
    The device also contains moving rolls 13 --15, vacuum labyrinth seal 16 ,. bottom suction 17, S-shaped guide over the suction rollers 13.

    Claims (7)
    [1]
    When the device is in operation, the water suspension of finely ground particles of tobacco othov through the inlet 4 enters the recess 5 of the wedge-shaped displacing body 2. When overflowing on the outside of the sides 6, the suspension loses acceleration and flows smoothly into the zone where the vacuum ducts 3 are located from the suspension begins the formation of a film of reconstituted tobacco on the nets 1. First, coarse and then fibrous particles of the tank are deposited. From the zone of the ducts, the joined layers of the film from both grids 1 along the three suction pads 17 located on the opposite sides are vertically fed to the S-shaped guide of the suction roll .13. The finished, having 75% moisture, film is sucked in the roll zone 14 to facilitate separation from the grids 1 and is directed from the device to desalting to a final moisture of 14-15%. The displacement body 2 is made with a recess 5 and sides 6 whose bevels are directed into the side of the grids 1 and the location of the outlet of the nozzle 4 below the upper edge of the beads 6 allows the suspension to flow evenly and eliminate the formation of bubbles by supplying the suspension to the area under its surface in the recess 5. The inlet 4 is run in incremental steps vayuschims to the outlet 9 and an inner diameter of connection pipe 4 to the horizontal tubular manifold 10 disposed inside the expelling of the body 2, allows to minimize the flow turbulence of slurry. The presence of valves 11 that are mounted to move in a vertical plane above the sides of the recess 5, allows you to adjust the flow of the suspension to the grids 1. Performing the lower end of the displacing body 2 with a groove communicating with the secondary header 12 allows you to return rich solid particles of tobacco suspension, passed the first vacuum duct 3, on the part of the grid 1, where the density of the film consistency allows you to further filter this suspension. The film thus obtained does not exfoliate and has good quality. U4 Claim 1. A device for making reconstituted tobacco film formed as a double sheet from a suspension of finely ground tobacco particles, mainly its waste, including two angled transporting grids for sedimentation of the suspension, vertically wedge-shaped displacing body, mounted under the angle vacuum duct nets and a suspension pipe, which is characterized in that, in order to improve the quality of the film obtained by preventing its separation, the A part of the displacing body is made with a recess for the suspension, limited by borgs with horizontally upper edges.
    [2]
    2. The device according to claim 1, in which the sides of the recesses have beveled portions directed outward toward the transporting nets.
    [3]
    3. The device according to paragraphs. 1 and 2, characterized in that the outlet of the supply pipe is located below the upper edge of the beads.
    [4]
    4. Device on PP. 1 and 3, characterized in that the inlet pipe communicates with a horizontal and tubular manifold located inside the displacement body.
    [5]
    5. Device on PP. 1, 3 and 4, characterized in that the inlet connection is made with a stepped diameter to the outlet opening.
    [6]
    6. The device according to claim 1, wherein the device is equipped with shutters installed so as to move in a vertical plane above the sides of the recess.
    [7]
    7. The device according to claim 1, which is based on the fact that at the lower end of the displacement, a groove made with an additional collection is made of the body.
