Abandoned packaging containers refer to various containers containing or contaminated with toxic hazardous waste or other toxic and harmful substances that have lost their original utilization value or have been abandoned or abandoned during packaging activities, such as waste iron barrels, waste plastic barrels, waste plastic woven bags, etc. After removing the toxic and harmful substances and dirt contained or contaminated in these discarded packaging containers, they can be processed into corresponding recycled packaging containers (such as recycled iron barrels, recycled plastic barrels, recycled packaging bags, etc.) or recycled materials (such as recycled metal materials that meet the requirements of smelting and hardware processing, or recycled plastic materials that meet the requirements of industrial plastic product processing, etc.) to achieve recycling. During this period, it is necessary to perform pre-treatment on discarded packaging containers, including sorting, residue extraction, crushing, crushing, cleaning, and drying.
In the crushing process, appropriate crushing methods should be selected based on the material of discarded packaging containers, the properties of residues, and the requirements for the utilization of recycled materials. There are usually two types of crushing methods: wet crushing and dry crushing. The wet crushing system should be equipped with closed automation equipment, secondary cleaning, vibrating screen dehydration, and filtering, magnetic separation, waste gas collection, waste water purification and circulation facilities. When dry crushing is adopted, nitrogen, spraying and other safety protection measures shall be selected according to the chemical characteristics of the residue; The shredding equipment should be closed for negative pressure operation, and a closed conveying device should be used, with separate exhaust gas collection and purification facilities, noise prevention equipment, etc., and the wastewater generated by spraying should be properly treated.
For example, in the tower type hazardous waste shredding system produced by our company, after placing waste packaging containers into pallets, the elevator drives the pallets to rise inside the sealed automatic device. When the tray containing the material reaches the position flush with the sealed compartment, the roller conveyor sends the tray to the crushing chamber of the shredder. At this time, the pushing device compresses the material downwards, accelerating the material crushing speed and improving the crushing efficiency. The material is crushed into small pieces by the shredder host and sent to the crushing pit through the discharge hopper. The system adopts fully enclosed conveying, crushing and fire protection design, with strong overall sealing and high factor of safety; there are two modes of active fire control and passive fire protection in production safety control; at the same time, it can flexibly match different models and tool designs to meet the requirements of coarse, medium, and fine crushing discharge.
If the funds are limited, you can also choose a regular version of the double-shaft shredder+fire protection system, which is a new trial run hazardous waste disposal production line for reference:
We look forward to your consultation with us at any time regarding the utilization and disposal equipment of waste packaging containers and their disposal plans.
