This creation belongs to the category of capital regeneration application skills, and details a waste plastic dry purification and separation receiving and takeover system. It consists of a V-shaped mixer feeding port, an outer cyclone collector, an outer bag collector, an inner cyclone collector, an inner bag collector, a dry separation section, and a separation device. The dry separation section is composed of an inner tube and an outer tube, with the outer tube covering the inner tube and holes evenly distributed on the inner tube. The feeding port is connected to the inlet of the inner tube; The separator consists of an inlet, an elbow, and a V-shaped outlet; There are two exits, identified as the outer air duct and the inner air duct. The angle between the outer air duct and the side air duct is 10-120 °, and the deviation angle of the centerline of the outer air duct from the degree line is -30-60 °; The inner pipe outlet is connected to the inlet elbow of the separator, the outer air duct is connected to the outer cyclone collector, the inner air duct is connected to the inner cyclone collector, the outer cyclone collector is connected to the outer bag collector through the pipeline, and the inner cyclone collector is connected to the inner bag collector through the pipeline. This creation has no secondary pollution of exhaust gas or wastewater, and the system will not be blocked.

The V-type mixer double-layer composite soft surface plastic foam board and its forming method belong to the category of building materials. The foam board consists of two layers: a soft surface layer and a hard bottom layer. The thickness of the soft surface layer is 2-10mm, and the thickness of the hard surface layer is 2-10mm; All are foam materials. The molding method includes the steps of batching, mixing, extruder extrusion, mold molding, and pre cooling in sequence. Its characteristic is that: mixing is to identify the inclusion of soft surface layer and hard bottom layer materials, and then the mixed soft surface layer and hard bottom layer materials are identified and added to two extruders. The two extruders are connected to the composite mold through a central connector, and then pre cooled after molding; The composite mold adopts dual channels, and the channel of the hard bottom layer material is parallel to the composite area at the mold mouth. The channel of the soft surface layer forms a 30 ° -45 ° angle with the channel of the hard bottom layer material when approaching the composite area; And the length of the composite straight section in the composite area is 20-30 millimeters. This product is more safe, with the bottom layer providing support and the two layers relying on the bonding and compatibility between the molecules of the two materials. It can be extruded in one go.
