Abstract

The invention relates to a method for separating a waste plastic thermal cracking solid product by using a separation device. The used separation device comprises a feeding hole, a separation machinebarrel, a separation screw, a strip-shaped sieve hole, a graphite packing, a separation motor, a medium outlet, a collection machine barrel, a collection screw, a reverse spiral discharging blade, anash outlet, a forward spiral discharging blade, a driving chain, a forward spiral sieving blade, a driving chain wheel, a driven chain wheel, a shaft coupler and a bearing seat. The method for separating the waste plastic thermal cracking solid product comprises a spiral conveying separation step and an ash automatic collection step. According to the method, automatic separation of cracking ash and a high-enthalpy solid heat storage medium is realized under the condition that the sealing is guaranteed; and the automatic and reliable collection of the cracking ash is realized, the production efficiency is improved and the sealing performance of the whole device is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pyrolysis devices for polymer materials, and in particular relates to a method for separating solid products of thermal cracking of waste plastics by using a separation device. Background technique [0002] Thermal cracking of waste plastics is to screen out waste plastics from garbage and heat them in an oxygen-free or low-oxygen airtight container. Waste plastics are thermally cracked into low-molecular compounds. The high polymer macromolecules in waste plastics are returned to low molecular weight or monomer state through cracking, and fuel oil, gas and carbon black are produced in this process, so as to realize the recycling, harmlessness and reduction of waste plastics deal with. [0003] Continuous thermal cracking of waste plastics is to continuously input waste plastics into the cracker at a certain feed rate, and thermal cracking occurs after heating and heat preservation of the cracker, and th...
