Abstract

The invention discloses a solid waste treatment device used after rigid polyurethane foam processing, and relates to the field of rigid polyurethane foam solid waste treatment. A driving motor; a first gear; a second gear; a first crushing roller and a second crushing roller; comprising a guide plate; and a discharging mechanism. Through the arrangement of the downward pressing mechanism, when the lower portion of an L-shaped material is completely crushed, the material continues to move downwards under the action of a conveying roller, and a second rack moves under the action of external force till a third gear does not make contact with a sixth gear any more; a push rod on one side of a second rack pops up under the action of a spring to provide pushing force for the material, so that the material is separated from a conveying roller and falls between a first crushing roller and a second crushing roller, and meanwhile, a pressing rod slides downwards under the action of gravity to be in contact with the outer wall of the material to provide downward pressure for the material; and the purpose of further improving the material crushing efficiency is achieved.

Description

technical field [0001] The invention relates to the field of solid waste treatment of rigid polyurethane foam, in particular to a solid waste treatment device used for processing rigid polyurethane foam. Background technique [0002] Polyurethane rigid foam is made of isocyanate and polyether as the main raw materials, under the action of various auxiliary agents such as foaming agent, catalyst, flame retardant, etc., mixed by special equipment, and foamed by high-pressure spraying. After the existing rigid polyurethane foam is used, it is necessary to cut the excess material by cutting, and the excess material will be crushed by a pulverizer and put into a container with a stirrer. Inside, spray the reactive, one-component moisture-curable polyphenyl polymethylene polyisocyanate adhesive, after mixing evenly, put the foam sprayed with glue into the mold for molding, and press the appropriate compression ratio, The finished product is obtained by curing at room temperature ...
