Description

Technical Field

[0001] The present application relates to the technical field of screw conveyor equipment, and more specifically, to a U-shaped screw conveyor sealing hanger. Background Art

[0002] U-shaped screw conveyor is a mechanical equipment used to convey powdered, granular and small block materials. Its main working part is a rotating screw shaft. When the length of the U-shaped screw conveyor exceeds 5 meters, the shaft will deform and sink due to the weight of the blades and the core shaft. When it sinks to a certain size, the blades and the shell will rub against each other when rotating. Excessive friction during the operation of the screw conveyor will cause damage to the blades of the screw conveyor. Utility Model Content

[0003] The utility model provides a U-shaped screw conveyor sealing hanger, which prevents the rotating shaft from sinking by arranging an adjustable hanger on the rotating shaft of the screw conveyor, thereby solving the problem of damage to the blades of the screw conveyor caused by the sinking of the rotating shaft.

[0004] The utility model is realized through the following technical solutions.

[0006] During the operation of the U-shaped screw conveyor, when the shaft sinks, the height of the adjustable hanger can be adjusted by turning the fastening nut. Since the shaft connecting plate on the adjustable hanger is connected to the shaft, the height of the shaft of the U-shaped screw conveyor can be adjusted to prevent the shaft from sinking.

[0007] In a further technical solution, in order to reduce the wear between the adjustable hanger housing and the short shaft, a wear-resistant sleeve is provided between the short shaft and the housing, the wear-resistant sleeve is installed on the housing, and the wear-resistant sleeve is arranged between two shaft clamp washers.

[0009] Furthermore, in order to prevent the suspension rod from shaking when adjusting and tightening the nut, a guide plate is provided in the U-shaped screw conveyor, and a through hole is provided on the guide plate, and the suspension rod passes through the through hole.

[0010] When adjusting the rotating shaft in the U-shaped screw conveyor by tightening the fixing nut, prevent the suspension rod from shaking too much to cause the diamond-shaped blades to rub against the inner walls on the left and right sides of the U-shaped screw conveyor.

[0011] Furthermore, in order to facilitate the disassembly of the guide plate, the guide plate is connected to the housing of the U-shaped screw conveyor through an angle iron, the angle iron is connected to the housing of the U-shaped screw conveyor through bolts, and the guide plate is connected to the angle iron through bolts.

[0012] Furthermore, in order to facilitate the addition of lubricating oil to the short shaft, an oil filling groove is provided at the center of the boom, the oil filling groove is connected to the oil nozzle on the shell, and the oil nozzle is connected to the oil groove in the shell.

[0013] The technical effects of the utility model are:

[0014] The present application arranges an adjustable hanger on the rotating shaft of the U-shaped screw conveyor. When the rotating shaft sinks, the position of the rotating shaft is adjusted by adjusting the adjustable hanger, thereby avoiding prolonged friction between the rotating shaft blades and the U-shaped screw conveyor housing, and preventing damage to the blades of the U-shaped screw conveyor due to the sinking of the rotating shaft.
