Description
Technical Field
The invention belongs to the technical field of material conveying equipment, and particularly relates to a multi-discharge-port spiral conveyor.
Background
The screw conveyor is roughly divided into a shaft screw conveyor and a shaftless screw conveyor in the conveying form, and is divided into a U-shaped screw conveyor and a tubular screw conveyor in the appearance. The working principle of the screw conveyor is that a rotating screw blade pushes materials to convey the materials. The shaftless screw conveyor is suitable for non-viscous dry powder materials and small particle materials (such as cement, fly ash, lime, grains and the like), and the shaftless screw conveyor is suitable for conveying viscous and easy-to-wind materials. When the screw shaft rotates, the materials can only move forwards along the bottom of the conveyor under the pushing of the blades due to the gravity of the materials and the friction force generated between the materials and the wall of the groove body. In order to place the screw shafts in a favorable tension, the drive and discharge openings are generally placed at the same end of the conveyor, with the feed opening being located as close as possible to the end of the other end.
Shaftless screw conveyer possesses long distance transport's ability, but when the material was carried the end, because helical blade's upper end is open, and the center does not have the axle, the material is difficult to block up wherein, but the material also is difficult to hold pressure, and the extrusion force is weak, can only pass through great export at the end, drops through the material dead weight. Therefore, the shaftless screw conveying has the defects that the discharging capacity of the discharging port is weak, the materials are difficult to crush in the discharging port, and the working efficiency is low.
The shaft screw conveyer is provided with a closed pipe sleeved outside the shaft screw conveyer, so that the materials can be stored and extruded out through a smaller outlet through extrusion force to form a closed material seal. However, the phenomenon that the material is blocked in the shaft screw conveyor is easy to occur, and the shaft screw conveyor cannot finish long-distance transportation because the central shaft is processed very long and is easily non-concentric and has great processing difficulty.
Therefore, for the transportation of materials in a long distance, the outlet of the materials is in a sealed state, and the purpose that the materials are not blocked and can be crushed to a certain extent is desired, the above-mentioned screw conveyer with the shaft and the screw conveyer without the shaft can not achieve the purpose.
The Chinese invention patent ZL202011486111.X discloses a double-screw conveyor which can realize the sealing of a discharge port, the difficult blockage and the crushing of materials and the long-distance transportation at the same time. When the double-screw conveyer is used, the inventor finds that the double-screw conveyer has the following problems: the discharge gate can only set up at screw conveyer's end to can only carry to a discharge gate. If the same twin screw conveyor is required to convey multiple devices (e.g., drying rooms), distribution cannot be accomplished. In addition, in the conveying process, the discharge port is positioned right below the end part of the shaftless spiral conveying mechanism, so that the spatial layout of equipment is limited.
