Description

Technical Field

[0001] This utility model relates to the field of polyvinyl chloride (PVC) cable material granulation production and processing technology, and more specifically, to a rapid cooling device for PVC cable material granulation. Background Technology

[0002] PVC cable material is made from polyvinyl chloride as the base resin, with added stabilizers, plasticizers such as dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, and trioctyl trimellitate, as well as inorganic fillers such as calcium carbonate, additives, and lubricants, and is prepared by mixing, kneading, and extrusion.

[0003] A search revealed a rapid cooling device for a granulator, with publication number CN212949113U. This device includes a conveyor frame, an anti-sticking roller mounted on the conveyor frame, a first air-cooling component, and a second air-cooling component. The conveyor frame is located between the extrusion mechanism and the pelletizing mechanism of the granulator. Linear extruded material passes through the anti-sticking roller, the first air-cooling component, and the second air-cooling component before entering the pelletizing mechanism. The conveyor frame has upwardly protruding sidewalls on both sides. The anti-sticking roller is mounted on the sidewalls, and at least one row of toothed combs is fixed axially on the anti-sticking roller, separating two adjacent linear extruded materials. The first and second air-cooling components are located above and below the linear extruded materials, respectively, and are staggered along the length of the conveyor frame. The first and second air-cooling components respectively supply air to the linear extruded material. This device solves the problems of extruded material adhesion, uneven cooling effect, and low cooling efficiency in granulators.

[0004] Common rapid cooling devices for PVC cable material granulation mostly use water-cooling boxes for cooling. As the material continues to enter the water-cooling box, the water at the bottom of the box gradually heats up, which is not conducive to heat dissipation and cooling, thus affecting the cooling performance of PVC cable material granulation. Therefore, we propose a rapid cooling device for PVC cable material granulation to solve the above-mentioned problems. Utility Model Content
