Description

Technical Field

[0001] The utility model belongs to the technical field of waste treatment, and in particular relates to a device for resource utilization of solid waste. Background Art

[0002] Construction waste refers to the general term for waste generated by people in production activities in the construction industry such as demolition, construction, and decoration. Construction waste can be divided into concrete blocks, crushed stone blocks, waste mortar, waste plastic, waste metal, waste bamboo and wood, etc. A large number of old buildings have been demolished. In this process, construction waste has become an invisible "metabolite" that hinders urban construction. Although most construction waste is non-toxic and harmless, if it is simply landfilled, it will not only affect the urban environment and waste land resources, but also cause huge waste of energy and resources. After searching, the patent with application number 202023007466.4 discloses a solid waste treatment and utilization device for construction projects, wherein a treatment box is installed above the base, a feed port is opened above the treatment box, and rotating rollers are symmetrically installed inside the treatment box, and crushing rollers are sleeved on the rotating spokes. Discharge doors are hinged on both sides of the treatment box, and permanent magnets are symmetrically installed on the inner sides of the discharge doors.

[0003] However, during actual use, the applicant found that in the process of adsorbing the iron waste in the crushed solid waste through the permanent magnets on both sides, it was only possible to collect the iron waste close to the permanent magnets, while the iron waste far away from the permanent magnets could not be effectively adsorbed and collected, resulting in the iron waste in the solid waste being unable to be fully utilized as a resource. In view of this, we proposed a device for solid waste resource utilization. Utility Model Content
