Abstract

The invention belongs to the technical field of plastic manufacturing, and specifically discloses a plastic particle mixing dryer comprising a material barrel and a discharging hopper. The inner wallof the material barrel is provided with a plurality of columnar bulges, and a rotating shaft is provided with helical blades; the top of the rotating shaft is provided with an end cam, and the rotating shaft and the end cam are internally provided with through holes which communicate with each other; the side wall of the rotating shaft in the material barrel is provided with air outlets which communicate with the through holes; a support frame is provided with a cylinder, and the lower end face of an ejector rod in the cylinder abuts against the concave side of the end cam; a coil is wound onthe outer wall of the cylinder, and connected to an AC motor; and the outer wall of the cylinder is provided with a one-way air inlet valve and a one-way air outlet valve, and a hot air pipe communicating with the through holes is installed between the one-way air outlet valve and the end cam. According to the technical scheme, hot air is intermittently discharged into a drying oven through the quick reciprocating motion of a cylinder piston, so that plastic particles are switched between two motion states, namely irregular movement and falling-down, and the plastic particles are mixed thoroughly.

Description

technical field [0001] The invention belongs to the technical field of plastic manufacturing and processing, and in particular relates to a mixing dryer for plastic particles. Background technique [0002] Starting from the synthesis of plastics, almost all thermoplastics have to go through the process of granulation. In addition to new materials that need to be granulated, dyeing, filling, reinforcement, and waste recycling in processing and production all need to be re-granulated. Traditional granulation technology There are two methods of hot granulation and cold granulation. During the plastic granulation process, in order to prevent the plastic granules from being deformed or melted due to excessive temperature, cold water is often used for cooling treatment. Therefore, drying operation is required after the granulation is completed. There are many factors that affect the drying effect of plastic particles, including drying temperature, drying time and air flow, etc.; h...
