Description

Storage device is used in polyethylene production Technical Field The utility model relates to the technical field of polyethylene production, in particular to a storage device for polyethylene production. Background Polyethylene is a thermoplastic resin prepared by polymerization reaction of ethylene monomers, and is widely applied to packaging (such as plastic bags, plastic films, geomembranes, bottles and the like), insulation layers and sheaths of wires and cables, hot water pipes and air heating pipes, petroleum and natural gas conveying pipelines, automotive upholstery, greenhouse covering materials and the like, and is usually in a milky wax particle material state after the polyethylene production is completed. Polyethylene is a thermoplastic plastic, odorless, tasteless, nontoxic and flammable, and during the molding process, polyethylene resin is extruded and granulated to form milky wax-like particles, and a sealed tank or a sealed bag is generally used for sealing and storing. When polyethylene is stored in the existing sealed tank body, polyethylene cannot be filtered, because polyethylene is conveyed to the storage tank body through a conveying pipeline after production is completed, certain powder can be produced by polyethylene particles through cutting, extrusion, friction and collision, and the polyethylene powder can directly influence the service performance of the polyethylene particles in later production, such as reduction of hardness, toughness, wear resistance, chemical stability and the like of a later finished product.
