Device and method for sorting building waste

Abstract

The invention discloses a device and method for sorting building waste. The outline, position, height and other information of materials are obtained through a laser sensor on the basis of a six-freedom-degree mechanical arm, and then, in the process that the six-freedom-degree mechanical arm is guided to grab materials, a tension sensor on the six-freedom-degree mechanical arm is used for obtaining the grabbed material weight information. Finally, the material density can be roughly estimated by utilizing material weight information and space volume information, and accordingly the material type is judged. A density recognition method is adopted for accurately sorting the building waste, and the sorting error rate is greatly reduced; through intelligent planning of the motion path of thesix-freedom-degree mechanical arm, the coordinates of the materials can be rapidly positioned, the material sorting efficiency is guaranteed as well, accurate material sorting is achieved, the work efficiency is greatly improved, and the human resource is saved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a device and method for sorting construction waste. Background technique [0002] With the acceleration of industrialization and urbanization, the construction industry will also develop rapidly, and the accompanying construction waste will also increase day by day. Construction waste is not real waste, but "gold" that has been misplaced. After sorting, rejecting or crushing, most construction waste can be reused as renewable resources such as: scrap steel bars, scrap iron wires, scrap wires and other metals, After sorting, concentration, and re-melting, it can be reprocessed and manufactured into steel products of various specifications. Among them, the effective separation of various materials in construction waste (including: wood, plastic, bricks, concrete, glass, steel, etc.) is a key technical link that affects the quality of construction waste aggregate r...

AI Technical Summary

Problems solved by technology

At present, screening, magnetic separation and winnowing are often used, but screening is a preliminary pre-sorting treatment for construction waste, and the sorting accuracy is low; magnetic separation removes iron and metal in the mixture of construction waste, and the sorting objects are relatively single; There is a technical problem in the selection method that light and heavy substances are mixed, and it is difficult to effectively separate them. The existing construction waste recycling technology is weak, and a professional technical system has not been formed, and there is often the phenomenon of incomplete separation.
