Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screw conveyors, and more specifically to a reinforcement device for screw conveyors. Background Art
[0002] A screw conveyor is a device for conveying solid powder materials. In the wet zinc smelting process, calcined materials are fed into the screw conveyor through the feeding port of a belt conveyor, and the calcined materials are added into the leaching reaction tank through the screw conveyor. During the long-term operation of the screw conveyor in the wet zinc smelting leaching feeding operation, the calcined materials wear the screw blades of the screw conveyor. At the same time, the steam in the reaction tank corrodes the screw blades, resulting in the decreasing diameter of the screw blades of the screw conveyor, making it difficult to convey the calcined materials inside the housing, causing the calcined materials to accumulate and coagulate continuously, increasing the cleaning difficulty for production personnel. Secondly, since the feeding port of the screw conveyor is sometimes blocked, causing the equipment to run idly, the shaft diameter of the conveyor drive shaft is severely worn, the bearings need to be replaced frequently, and the decreasing shaft diameter makes the original bearings unable to match when installed.

The blade repair structure includes a first spiral steel bar, a plurality of second spiral steel bars, and a plurality of fixing steel bars. A shaft body repair structure is fixedly arranged on the outside of the worn part. The shaft body repair structure includes a plurality of strip-shaped solder joints and a circular solder joint.
[0006] Further, the first spiral steel bar is fixed to the outside of the spiral auger blade. A plurality of the second spiral steel bars are fixedly connected in sequence outward on the outer ring of the first spiral steel bar.
