Description

Technical Field

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

[0002] Tubular screw conveyor is a kind of solid material conveying equipment commonly used in chemical, food, pharmaceutical and other industries. It uses spiral blades as conveying elements, and propels the material along the spiral line by rotating the spiral blades, thereby realizing the material conveying. However, in actual applications, if the length of the tubular screw conveyor is too long, the shaft will be deformed and sink due to the weight of the blades and the core shaft. When it sinks to a certain size, the blades and the tubular screw conveyor housing will rub against each other during rotation, thereby affecting the service life of the tubular screw conveyor. Utility Model Content

[0003] The utility model provides a tubular spiral sealing hanger. By arranging the hanger on the rotating shaft, the problem of friction between blades on the rotating shaft and the casing of the tubular spiral conveyor caused by sinking of the rotating shaft due to excessive length of the tubular spiral conveyor is prevented.

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

[0005] A tubular spiral sealing hanger, which is used to fix the rotating shaft of a tubular screw conveyor, includes: a mounting flange, which is fixedly arranged on the shell of the tubular screw conveyor, and is connected to a spoke plate by bolts, and the spoke plate is fixedly connected to the hanger shell, a short shaft is arranged in the hanger shell, the short shaft is rotatably connected to the hanger shell, the short shaft is installed in the hanger shell through a circular baffle, and both ends of the short shaft are fixedly connected to a core shaft connector, and both ends of the core shaft connector are fixedly connected to the rotating shaft of the tubular screw conveyor.

[0006] A hanger is arranged on the rotating shaft to prevent the hanger from sinking. The rotating shaft is fixedly connected to the core shaft connector. The short shaft and the rotating shaft rotate in the same direction at the same time. The spoke plate is connected to the mounting flange by bolts. The spoke plate is fixedly connected with a hanger shell to fix the hanger in a certain position, provide certain support to the rotating shaft, and prevent the rotating shaft from sinking.

[0007] In a further technical solution, in order to ensure that the position of the hanger is fixed, three spokes are arranged at equal intervals along the hanger shell.

[0008] Three spokes are arranged at equal intervals along the hanger shell to position the hanger and prevent the hanger from moving.

[0009] Furthermore, in order to prevent the lubricating oil in the hanger housing from leaking into the tubular screw conveyor, a felt sealing ring is provided on the short shaft, the felt sealing ring is fixedly connected to the short shaft through a shaft positioning bolt, the felt sealing ring is rotatably connected to the hanger housing, and a circular baffle is provided on the hanger housing, which is fixed to the hanger housing by bolts.

[0010] During the rotation of the short shaft, the felt seal ring and the short shaft rotate simultaneously, and the circular baffle prevents the felt seal ring and the short shaft from falling off from the hanger housing.

[0011] Furthermore, in order to prevent damage caused by long-term friction between the short shaft and the hanger housing, a polytetrafluoroethylene wear-resistant sleeve is provided between the hanger housing and the short shaft, and the polytetrafluoroethylene wear-resistant sleeve is installed on the hanger housing.

[0012] Furthermore, in order to facilitate the addition of lubricating oil into the ground hanger, a refueling channel is provided at the center of the three spokes perpendicular to the ground. The refueling channel is connected to the oil nozzle on the hanger shell, and the oil nozzle is connected to the oil tank in the hanger shell. A sealing cover is provided at the oil inlet of the refueling channel.

[0013] The lubricating oil enters from the oil inlet of the refueling channel, passes through the oil nozzle and enters the oil tank in the hanger housing. The function of the sealing cover is to prevent dust from entering the refueling channel.

[0014] The technical effects of the utility model are:

[0015] The present application arranges a hanger on the rotating shaft to prevent the rotating shaft from sinking when the conveying distance of the tubular screw conveyor is long, which causes friction between the blades and the tubular screw conveyor casing, thereby extending the service life of the tubular screw conveyor; the spokes are arranged at equal intervals to facilitate fixing the position of the hanger and reduce the overall weight of the hanger for easy installation.
