3. A sluice feeder according to claim 1, characterized in that each blade is divided into parts located along the axis of the shaft and separated by disks with the possibility of displacing the parts relative to one another in the angular direction.

The invention relates to the pneumatic conveying of bulk materials and can be used in various industrial sectors for the dosing of coarse metal chips and other lump materials.

The purpose of the invention is to increase reliability.

Figure 1 shows the lock feeder, a longitudinal section; in Fig.2 a section aa in Fig.1; in FIG. 3, node 1 in FIG. 2; figure 4 - node P in figure 2.

The sluice feeder comprises a housing 1 with loading 2 and 3 discharge openings that are displaced along the rotation of the rotor. S end, the walls 4 of the housing 1 is mounted; with radial lobes b. located between the end discs 7 and discs 8. The blades 6 are made of a package of elastic plates of conical plates fixed by means of clamping strips 9 on the rods of the rotor shaft 10 by means of special studs 11 and nuts 12. At the same time, the clamping strips 9 simultaneously act as disc stops 8. Free

The ends of the plates have a series of holes 13, into which the special rivets 14 are inserted, providing a guaranteed clearance for free movement.

plates bending one relative to another. Moreover, in order to achieve a smooth bend, the faces 10 are smoothly mated with the diameter of the rotor shaft with the radius link.

To prevent dust from entering the gap between the plates, the blades are equipped with wear-resistant U-shaped Planks 15, covering their free ends.

The device works as follows.

Bulk material flows from the top through the loading opening 2 and fills the rotor cells 5. When

rotation of the rotor 5, the material from the cells pours out through the discharge opening 3, large clumps of chips, hitting between the end of the blade 6 and the wall of the nozzle, do not break the blade,

consisting of a package of elastic thin plates, since the latter are bent (Figures 2 and 3), they will pass by the lump, after which the lump will fall into another cell of the rotor.

Claims (3)

1. Sluice feeder for pneumatic conveying of bulk materials, comprising a housing with loading and unloading openings and end disks placed from its opposite ends, located on it by means of said pressure plates of rotor blade plates made flexible and placed with the possibility of their free movement ends relative to each other in the direction of their longitudinal axis. 2. The lock feeder according to claim 1, characterized in that each blade is provided with a U-shaped bar covering the free end of its plates and made of wear-resistant material. 3. The gate feeder according to claim 1, characterized in that each blade is divided into parts located along the axis of the shaft and separated by disks with the possibility of displacement of the parts relative to one another in the angular direction.
