Non-contact type corner box

Abstract

The invention discloses a non-contact type corner box. The non-contact type corner box comprises a box shell, a pipe chain, a feeding pipe and a discharging pipe; a pipe chain wheel corresponding to the pipe chain is arranged inside the box shell and supported on the box shell rotationally through a chain wheel shaft; an annular trough plate is arranged on the tooth portion of the pipe chain wheel; the center line of the annular trough plate and the center line of the pipe chain wheel are located on the same straight line; and the section of a groove of the annular trough plate is matched witha scraper blade on the pipe chain in shape. By adoption of the non-contact type corner box, contact and friction between the conveying pipe chain and a conveying pipeline can be avoided, the workingis stable and reliable, and the service life is long.

Description

technical field [0001] The invention relates to a conveying machine, in particular to a corner device of a pipe chain conveying machine. Background technique [0002] The pipe chain conveyor uses the pipe chain scraper in the closed conveying pipeline as the conveying member to drive the material to move along the pipe. The pipe chain scraper is installed on the conveying pipe chain, and the conveying pipe chain corresponds to the conveying pipe. The whole pipe chain conveyor forms An annular channel, with a material inlet and an outlet on the circular conveying channel. The pipe chain conveyor has a compact structure and takes up little space. It can change the conveying direction in three dimensions, and the material is in a relatively closed conveying pipeline during the conveying process. Therefore, it has been widely used in many occasions that require sealing, cleanliness, and environmental protection. However, while the pipe chain conveyor can adapt to the three-dimen...

[0002] The pipe chain conveyor uses the pipe chain scraper in the closed conveying pipeline as the conveying member to drive the material to move along the pipe. The pipe chain scraper is installed on the conveying pipe chain, and the conveying pipe chain corresponds to the conveying pipe. The whole pipe chain conveyor forms An annular channel, with a material inlet and an outlet on the circular conveying channel. The pipe chain conveyor has a compact structure and takes up little space. It can change the conveying direction in three dimensions, and the material is in a relatively closed conveying pipeline during the conveying process. Therefore, it has been widely used in many occasions that require sealing, cleanliness, and environmental protection. However, while the pipe chain conveyor can adapt to the three-dimensional direction of conveying materials, it must also have corners of the conveying channel. At the corners of the conveying channel, ordinary pipe chain conveyors The conveying pipe chain runs in a curved conveying pipe. At this time, the conveying scraper and the inner wall of the conveying pipe will be in rigid contact and there will be relative slippage, and there will be serious friction between the conveying scraper and the inner wall of the conveying pipe, which will not only increase It will increase the working resistance, and also cause the wear of the conveying scraper and the conveying pipeline, which will affect the service life of the pipe chain conveyor
