Abstract

The invention relates to a device and method for comprehensively utilizing construction waste, and belongs to the technical field of construction waste disposal. The device comprises a machine frame.A pulverizing machine for pulverizing the construction waste is arranged on the machine frame. The pulverizing machine comprises a feed port and a discharge port. A screening plate is arranged on themachine frame and located under the discharge port. A pressing roller is arranged on the screening plate. An electromagnet is arranged in the pressing roller. A recovery hopper is arranged on one sideof the screening plate. A discharge hopper is arranged under the screening plate. A driving piece for driving the pressing roller to get close to or away from the recovery hopper is arranged on the machine frame. The driving piece drives the pressing roller to roll on the screening plate so as to further crush the construction waste; scrap iron in the construction waste is attracted to the surface of the pressing roller through the electromagnet, and other construction waste falls into the discharge hopper through the screening plate; and the aim of sorting out the scrap iron is realized, andthe scrap iron can be conveniently recovered.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a device and method for comprehensively utilizing construction waste. Background technique [0002] Construction waste refers to the dregs, spoils, waste materials, silt and other wastes generated during the construction, laying or demolition, and repair of various buildings, structures, and pipe networks by construction units or individuals. The recycling of garbage and municipal garbage resources can greatly reduce the landfill area of ​​garbage and reduce environmental pollution. [0003] At present, the processing and recycling of construction waste usually needs to be crushed and separated, and then metals such as waste steel bars, waste iron wires, waste wires and various scrap steel accessories are recovered, and the crushed construction waste is used for masonry mortar and plastering Mortar, concrete cushion, etc., or used to make building blocks, pa...
