Screw conveyor centering ring type intermediate support device

1. Centering ring type intermediate support device

The centering ring type intermediate support device divides the long original casing and the spiral blade and the pipe shaft into two sections, and the centering ring, the bearing and the sealing ring are added at the section of the pipe shaft to form the pipe shaft. Intermediate support. The two pipe shafts are coupled by a coupling, and the blades are added to the two pipe shafts, and the function is to overcome the powder caused by the discontinuous blade pushing the powder after the setting device is added. Partial accumulation. The flange on the housing is mainly for the connection of the housing after the segmentation. The distance ring effectively controls the distance between the two centering rings, and also centers the two sections to ensure a reasonable coaxiality. This slows down the assembly of the screw conveyor.

2. Adjustable centering support device

The housing of this configuration is still integral, except that a window is opened above the housing and sealed by the nozzle, the tray and the cover. The tube shaft is assembled in two pieces, and an intermediate shaft is inserted into the left and right sides of the tube shaft, and assembled by bolts. The tube shaft is hoisted on the cover by means of bearings, U-bolts and bearings. In the work, once the spiral blade and the shell are found to be rubbed, the center position of the blade can be adjusted by the U-bolt to meet the needs of the screw conveyor for normal operation.

In general, the centering ring structure is mostly used on a screw conveyor with a small pipe shaft diameter, and the adjustable centering support structure is mostly used on a screw conveyor with a large pipe shaft diameter and a U-shaped casing. Due to the different manufacturing and assembly processes of the two, they can be selected according to the specific conditions of the production plant.
