Classification recovery device of construction waste

Abstract

The invention discloses a classification recovery device of construction waste. The classification recovery device comprises a classification box, an inclined surface part is arranged at the bottom ofthe classification box, a magnetic conveying belt is installed on the inclined surface part, and a first discharging port is formed in the side wall, connected with the classification box, of the topend of the inclined surface part; a second discharging port is formed in the side wall, connected with the classification box, of the bottom end of the inclined surface part, and a third dischargingport is formed in the side wall of the top of the classification box; a scraper is arranged on the outer side of the first discharging port, and a first material storage box is arranged below the first discharging port; a crushing mechanism is arranged below the second discharging port, and a second material storage box is arranged below the third discharging port; a water inlet pipe and a feedingpipe are arranged at the top of the classification box, a stirring paddle is arranged in the classification box, and the bottoms of the first material storage box, the crushing mechanism and the second material storage box are connected with a water return pipe; and the water return pipe is connected with the classification box through a water pump. According to the device, the defects in the prior art can be improved, the dust raising inhibition effect in a crushing process is improved, and the crushing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of construction waste treatment, in particular to a sorting and recovery device for construction waste. Background technique [0002] With the continuous acceleration of the urbanization process in our country, a large amount of construction waste is produced in the process of urban construction. Construction waste generally includes combustible materials such as wood chips and waste paper, and directly usable materials such as wood, metal, and plastic, as well as construction waste soil, concrete fragments, and bricks. If the construction waste is directly discarded and buried, it will not only affect the environment, but also cause a serious waste of resources. Chinese invention patent CN 103264043 B discloses a construction waste sorting machine and its classification system, which realizes the classification and sorting of construction waste. However, this sorter generates a lot of dust when crushing c...
