This utility model relates to the field of
coating production technology and discloses a material conveying anti-clogging structure for the production of
polyvinyl chloride anti-
corrosion coatings, including: a
storage tank; a hammering structure, the hammering structure including a support frame, a main shaft, fixed rings and swing arms. The main shaft is rotatably installed inside the conveying
pipe through the support frame. The main shaft extends radially along the conveying
pipe. Several fixed rings are fixedly installed on the main shaft. Each fixed ring is rotatably connected to several swing arms. The main shaft is driven to rotate by an
auger conveyor. The main shaft drives each fixed ring and the multiple swing arms on each fixed ring to rotate circumferentially. The multiple swing arms are thrown out under the action of
centrifugal force, continuously squeezing and shearing the material in the conveying
pipe, effectively destroying the adhering
coating layer and deposits. The hinged design prevents the swing arms from jamming, prevents material adhesion and accumulation, and prevents problems before they occur. It is a purely mechanical structure with high reliability. It does not require an external gas / liquid source, has no
pollution risk, improves the stability of the material conveying process, and reduces the probability of clogging.
