Centering ring-type intermediate support device for screw conveyor
1. Centering ring type intermediate support device
The centering ring type intermediate support device is to cut the longer original shell, spiral blade and tube shaft into two sections, and add centering rings, bearings and sealing rings to the cut parts of the tube shaft to form the tube shaft. intermediate support. The two tube shafts are connected by a coupling, and paddles are installed on both tube shafts. Its function is to overcome the powder failure caused by the discontinuity of the blades that push the powder after adding a centering device. Material accumulates locally. The main purpose of installing a flange on the shell is to facilitate the connection of the shell after being cut. The distance ring effectively controls the distance between the two centering rings and also plays a centering role in the two shell sections to ensure their reasonable coaxiality. This slows down the assembly difficulty of the screw conveyor.
2. Adjustable centering support device
The casing of this structural form is still a whole, except that a window is opened above the casing and is sealed by a nozzle, a connecting plate and a cover plate. The tube shaft is assembled in two sections. An intermediate shaft is inserted into the left and right sections of the tube shaft, and bolts are used to assemble them into one piece. The tube shaft is hoisted on the cover plate through components such as supports, U-shaped bolts and bearings. During work, once it is found that there is friction between the spiral blades and the shell, the center position of the blades can be adjusted through U-shaped bolts to meet the needs of the normal operation of the screw conveyor.
Generally speaking, the centering ring structure is mostly used on screw conveyors with smaller pipe shaft diameters, while the adjustable centering support structure is mostly used on screw conveyors with larger pipe shaft diameters and U-shaped shells. Since the manufacturing and assembly processes of the two are different, they can be selected according to the specific conditions of the manufacturer.
