Anti-blocking reverse-flow type PVC (polyvinyl chloride) sheet filler

The utility model relates to the technical field of fillers, in particular to an anti-blocking reverse flow type PVC (polyvinyl chloride) sheet filler which comprises a PVC sheet plate, a reverse flow support plate is mounted on the outer plate surface of the PVC sheet plate, and an anti-blocking part is rotatably mounted in the PVC sheet plate; the anti-blocking part comprises a plurality of outer covers, and an inner material cavity is formed in each outer cover; according to the anti-blocking reverse flow type PVC sheet filler, the surface contact area of cooling water can be increased through the arranged PVC sheet plate structure, meanwhile, the arranged reverse flow supporting plate can prolong the stagnant flow time of condensate, and the condensation efficiency is improved; the anti-blocking part rotatably installed in the PVC sheet plate can rotate when the flow amount of condensate is large, the situation that the heat conduction filler in the PVC sheet plate is blocked when the structure is fixed i
