A pine resin insulated and anti-clogging conveying pipeline

Abstract

This utility model provides a pine resin heat-insulating and anti-clogging conveying pipeline, relating to the technical field of pine resin conveying devices. It includes a main pipe, which comprises a liquid inlet section, a narrowing section, a throat section, an expanding section, and a liquid outlet section, connected end-to-end and fixed to each other. The narrowing section has a truncated conical structure, with the inner diameter of its input end being the same as that of the liquid inlet section, and the inner diameter of its output end being the same as that of the throat section. A heating mechanism is fixedly installed on the outer wall of the throat section, and an insulation pipe is fixedly installed on the outer sleeve of the main pipe. Through the variable diameter structure of narrowing for acceleration and expanding for flow stabilization, the flow state of the resin is actively optimized. After entering the throat section, the kinetic energy of the resin is significantly increased, breaking the laminar flow state and eliminating the stagnant zone at the pipe wall boundary, preventing impurities from depositing. Combined with precise local heating in the throat section, replacing full-line heating, energy consumption is significantly reduced. The external insulation pipe further suppresses heat loss, effectively solving the pipeline blockage problem caused by temperature decreases during long-distance transport, significantly improving production continuity and reducing maintenance costs.
