Abstract
Description

[0002] Material conveying systems are an essential component of modern industrial production, particularly in the chemical, food processing, pharmaceutical, and mineral processing industries, where the transport of highly viscous materials is a common requirement. However, traditional material conveying piping systems often face numerous challenges when handling these high-viscosity materials. The most prominent issue is the tendency for materials to become clogged in bends, rising sections, or narrow areas within the pipeline during transport.
[0003] Under existing technology, operators typically observe the material flow from the pipe outlet. If there are signs of poor discharge and the pipe is about to become clogged, they stop feeding the material to the inlet to clear the pipe. While this method can prevent production accidents caused by pipe blockage to a certain extent, it is relatively narrow inside the pipe, making manual clearing difficult. Furthermore, stopping the machine for clearing also reduces production capacity to a certain extent, resulting in certain limitations. Therefore, the inventors have proposed another solution.
