Abstract

PURPOSE:To facilitate cleaning by carrying out granular powder remaining in a coupling casing by compressed air in an apparatus incorporating two, vertical and horizontal screw conveyors in two casings coupled to each other by a coupling casing in such a manner as to meet at right angles. CONSTITUTION:A conveying apparatus for granular powder incorporates two, vertical and horizontal screw conveyors 4, 5 connected to each other in such a manner as to meet at right angles in two, vertical and horizontal casings 2, 3 coupled to each other by a coupling casing 1. The above coupling casing 1 is provided with a jet orifice 6 for jetting out compressed air to the interior thereof. That is, one or plural jet orifices 6 are disposed on both side wall plates 8 of the coupling casing 1 formed by an inclined bottom wall plate 7, both side wall plates 8 and a ceiling late 9. In this arrangement, granular pow der remaining in the coupling casing 1 is blown off into the vertical screw conveyor 4 by jetting out compressed air into the coupling casing 1 from the jet orifices 6.

Description

[Detailed Description of the Invention] This invention has 5 horizontal and vertical screw conveyors connected by a connecting casing. The connecting casing of a conveying device for powder and granular materials is connected from one screw conveyor to the other screw conveyor, with the purpose of transporting the powder and granules transported from one screw conveyor to the other screw conveyor without any remaining particles. A device for conveying powder and granules to the other screw conveyor without leaving any particles remaining, the connecting casing of the casing is provided with one or more jetting ports for spouting pressurized air toward the inside of the casing, and the pressurized air is Pressure air is ejected from the spout into the connected casing, thereby preventing powder and granules remaining in the connected casing from being blown away and remaining in the vertical screw conveyor. In this embodiment, the connected casing is surrounded by an inclined bottom wall plate, both side wall plates, and a ceiling plate, and seven or more pressure points are applied to the inclined bottom claw plate or both side wall plates, etc. An air outlet is provided or sealed in the connecting casing with an inclined bottom claw plate, both side wall plates and a ceiling plate, and an air box is provided on the arm plate of the connecting casing, The upper opening of the air box is sealed with an armor plate-like lid plate that is superimposed substantially orthogonally to the conveying direction of the plural band sheet metal powder particles, and the band of the armor plate-like lid plate is are adjacent to each other with a small gap between them, and pressurized air is charged into the air box, and the pressurized air is ejected from the small gap in the transport direction in the adjacent part of the armor plate-like executive lid plate. [This is to prevent the powder particles remaining in the casing from being blown away and remaining in the vertical screw conveyor.]

In general, 5 transversely connected casings are connected in 5 transversely connected casings.
In a powder and granule transport device equipped with a screw conveyor, some of the powder extruded by one screw conveyor and placed on the wings of the other screw conveyor is transferred to the other screw conveyor. However, how should the screw conveyor 8 and the other screw conveyor wing be brought close to each other? A space is created where the force cannot reach, and some powder particles remain on the sloping FC wall board in that space. The body tl- has the disadvantage of having to be cleaned. On the other hand, the present invention eliminates the drawbacks of the conventional conveying device, and according to the present invention, five bonds are crossed in one vertical and horizontal casing connected by a connecting casing. In a powder and granular material conveyance device that is equipped with a screw conveyor connected to
The connecting casing of the seventh casing is provided with seven or more jetting ports for jetting out pressurized air toward the inside thereof, and all of the pressurized air is jetted out from the jetting ports into the connecting casing. The powder and granules remaining in the connecting casing are prevented from being blown away and remaining in the vertical screw conveyor, so the powder and granules remaining in the connecting casing are blown out from the connecting caning VC. Since the powder is blown away and transported into the other screw conveyor by the pressurized air, it is possible to transport the powder without leaving any residue even if the slope angle of the inclined bottom wall plate of the connecting casing is gentle. Useful.

The invention of this application will be explained next with reference to the drawings.
