Description

The invention may find application in the building materials industry, in the chemical industry, and in other branches of the national economy for the dosing of powdered materials.

Known plate feeders of powdered materials are known, containing a hopper, in the lower part of which a disk and a drop knife are rotatably mounted in a housing.

The proposed plate feeder differs from the known ones in that the disk is made, but at least with one radially spaced slit. This ensures a uniform supply and dispensing of material with its simultaneous distribution over the earth, Adi.

The resetting rod can be movably mounted on the disk with the possibility of adjusting the slit section. This can regulate performance.

FIG. 1 depicts the proposed feeder; pas figs. 2 shows a section along AA of FIG. one; in fig. 3 is a section along BB in FIG. 2

The plate feeder of powdered materials consists of a hopper 1 for a powdered material, to the bottom of which a case 2 is attached with a disk 4 mounted on the axis of rotation 3 and a nonsupillary frame 5 with a grid (grid) of 6

perception of material pressure. The disk 4 has radially spaced slits 7, and the slide is movably fixed with the possibility of adjusting their cross section drop knives 8. The rotation of the disk 4 is transmitted from the actuator 9 through the drive gear 10 and the gear ring 11.

Dish-shaped food works as follows.

The powdery material in the hopper 1, under its own weight, goes down and reaches the grid 6, which perceives the pressure of the material column. The penetration through the latter, the material gets on the rotating disk 4. When working with materials having high humidity, it is possible to install a small vibrator to prevent it from hanging on the grille. Thus, on disk 4 is a layer

material characterized by raviomeric density throughout the volume. As the disc 4 rotates, a friction force is created on the lower and upper surface of the material layer. Resistance from the side of the grid b will be

more, since its cells (not shown in the drawing) will prevent the material from rotating with the disk. When the disk is rotated, the dumping knives 8 cut a thin layer of material that passes through H1, spruce

7 and fails PNPs.

The performance of the plate feeder depends on the number of revolutions of the disk 4, the number of slits 7, the length of the slit and the height of the material being cut.
