Description

There are known devices for feeding bulk or powdery materials to filling machines or similar devices, in which the material comes from a bunker hopper holed down onto a rotating table with a fixed scraper underneath to drop material into the receiver, with the possibility of adjusting the gap between the hopper and the table. mobile on height of a cuff.

In the described device, the lower edges of the cuff and the hopper pipes are cut along a helical line in the direction from the installation site of the scraper to the direction of rotation of the table with the greatest gap height at the drop site, thus improving the conditions for removing material from the table.

FIG. 1 shows a device for feeding bulk or powdery materials to filling machines or similar devices in a vertical section; in fig. 2 - the same front view.

Bulk material enters the bunker /, which is the lowest truncated cone, with its socket facing down.

Under the hopper 1 there is a table 2 with a vertical axis of rotation. The diameter of the table 2 is larger than the lower diameter of the bunker.

The lower edge of the bunker pipe / is cut along a helical line and between it and the surface of the table 2 there is a gap 4, whose height around the circumference of the bin increases in the direction of the rotation of the table 2. The maximum height of the gap 4 ends at the place of material dropping against the stroke 5, set vertically butt to the generatrix of the cone of the hopper 7 and at an acute angle to the tangent lower edge of the cone. The bottom edge of the stroke 5 is close to the surface of the table 2.

The gap 4 may be blocked in a larger “lesser degree” by moving up and down with a cylindrical cuff 6 worn

on the bunker tube. The lower edge of the cuff is also cut along a helix, but with a significantly smaller pitch than that of the bunker pipe.

Under the row 5 there is a pipe 7 serving to feed the product or material into the filling machine.

The material entering into the hopper 1 is placed on the table 2 and, when it rotates, passes into the gap 4, and then by the paddle 5 is sent to the pipe 7. Due to the clearance of the bunker section / bottom, the material, if it is caking, cannot be held up on the walls of the bunker Thus, the formed lumps of material cannot get stuck in the gap 4 due to its expanding cross-section and the presence of the paddle 5 dissecting the lumps of product brought to it. D. the adjustment of the degree of supply of the hole serves as a cuff 6.

In the case of stopping or reducing the reception of the head supplied by the machine, the excess product is diverted both from the pipe 7 and from the filled bin /, thanks to the difference between the drain planes 9 and 10 and the well U / into the collecting cone 12 and the drain auger 8.

Before m with t and 3 about b and e and and

Device for nodachi bulk or powdery materials in filling machines or similar devices, equipped with a hopper facing the bell down And located above the rotating table, and scraper to drop the material in the receiver, with the ability to adjust the gap between the bunker and the table using the sliding on the left side of the cuff, about; i and often because, in order to improve the conditions for removing material from the table, the bottom edges of the cuff and the hopper pipes are cut along a helical line in the direction from the installation Fork in the direction of rotation of the table with the greatest height of the gap at the place of material dropping
