How to solve ecological pollution with plastic mechanical mixer and granulator

December 05, 2023

At present, waste plastics are recycled to waste plastic processing plants for crushing, and then granulated through waste plastic granulators. The crushing noise is high, there is a lot of dust, and the labor environment for workers is poor. Screw extrusion granulation uses friction and electric heating to melt waste plastics, and then extrudes them into granules through screws. The entire process consumes a lot of energy.
In order to overcome the noise and dust caused by the crushing process of the existing waste plastic granulator, improve the working conditions of workers, overcome the excessive energy consumption in the existing waste plastic processing process, and reduce energy consumption, the waste plastic recycling granulator device includes: a material preparation room, a mixing shaft, an upper melting chamber, a frame, a mixing rod, a grid, a spacer, a lower melting chamber, a spiral blade, a screw, an intake pipe, a heating element, and a circulating gas inlet Fan, extrusion die, and transmission mechanism.
Its design principle: The material preparation chamber is connected to the upper melting chamber through a partition door, and the mixing rod is installed on the mixing shaft, driven by a transmission mechanism. The upper and lower melting chambers are separated by a grid, and the lower part of the mixing shaft is a spiral blade. The partition sleeve in the lower melting chamber allows the heated exhaust gas to enter the inlet of the circulating gas, which is connected to the inlet of the fan. The outlet of the fan is connected to the heating chamber, and heating elements are installed in the heating chamber, The outlet of the heating chamber is connected to the melting chamber through an intake pipe, and the transmission mechanism is a chain drive. The stirring shaft is driven to rotate by an electric motor after being decelerated by the chain drive.
The advantage of the equipment is that waste plastic is heated and melted by hot air, and the melted plastic is extruded and granulated by screws. The recycled waste plastic does not need to be crushed, thus avoiding noise and dust flying and improving the working conditions of workers; By controlling the temperature of the hot air, plastic can be prevented from degrading due to excessive temperature during the melting process. The hot air can be recycled, which reduces energy consumption.

Plastics play an important role in various fields of economic construction due to their excellent properties such as light weight, high strength, corrosion resistance, and easy processing. However, with the widespread application of plastics, the treatment of waste plastics has become a challenge. Waste plastics are difficult to degrade naturally, causing environmental pollution and resource waste, especially for packaging plastics, which account for a large proportion of waste plastics. The recycling and utilization of plastic waste is a way to turn waste into treasure, and the waste plastic granulator is a powerful assistant in solving ecological and environmental pollution.
