Abstract

This utility model discloses a cooling device for PVB resin powder production, comprising a cooling base, a mixing reaction assembly mounted on top of the cooling base, and a heat insulation assembly sleeved around the mixing reaction assembly. The mixing reaction assembly includes a reaction vessel, and a heat-conducting sleeve sleeved around the reaction vessel. Several sets of circumferentially distributed limiting slots are also provided on the outer side of the heat-conducting sleeve. This solution achieves uniform coverage and efficient cooling of the entire outer surface of the reaction vessel by arranging multiple sets of cooling pipes around the inner wall of the heat-conducting sleeve of the mixing reaction assembly and utilizing the precise structural matching and transition fit between the heat-conducting vessel and the cooling base. At the same time, the effective heat insulation effect of the heat insulation assembly reduces external heat interference, achieves stable and uniform internal temperature of the reaction vessel, and effectively prevents quality problems such as inconsistent particle size and mechanical property fluctuations in PVB resin powder due to temperature fluctuations, thereby significantly improving the quality stability and consistency of the product.
