Construction garbage crushing device

Abstract

The invention discloses a construction garbage crushing device, and belongs to the technical field of construction. The construction garbage crushing device comprises a first crushing box and a secondcrushing box; a first rotating shaft is transversely mounted in an inner cavity of the first crushing box; a crushing cylinder sleeves an outer ring of the first rotating shaft; a second rotating shaft is mounted on the inner side of the second crushing box; a crushing disc sleeves the outer wall of the second rotating shaft; a spiral feeder is mounted at the bottom of the second crushing box; the left end of the spiral feeder is connected with a drying cylinder; electric heating plates are mounted on the front and back sides of the drying cylinder; a damper is arranged at the bottom of the first crushing box; and an exhaust fan is mounted at the top of the drying cylinder. Construction garbage is crushed through the crushing cylinder and the crushing disc in sequence, so that the consistency of crushed particles is improved; the crushed particles are conveyed into the drying cylinder for heating; water vapor in the drying cylinder can be extracted out through the exhaust fan to maintain the dryness of an inner cavity of the drying cylinder; and the damper reduces and isolates the vibration, so that the device is operated more stably.

Description

technical field [0001] The invention relates to the technical field of building construction, and more specifically, to a construction waste crushing device. Background technique [0002] Construction waste has a wide range of erosive effects on our living environment. If we ignore construction waste for a long time, it will have a bad impact on urban environmental sanitation, living conditions, and land quality assessment. After a large amount of land is piled with construction waste, It will reduce the quality of the soil and reduce the production capacity of the soil. Therefore, it is necessary to carry out related treatment of construction waste, in which waste construction concrete and waste bricks are crushed to produce coarse and fine aggregates, which can be used to produce concrete, mortar or preparation of corresponding strength levels. Building material products such as blocks, wall panels, floor tiles, etc. are often damp due to the influence of rainy weather due...

[0002] Construction waste has a wide range of erosive effects on our living environment. If we ignore construction waste for a long time, it will have a bad impact on urban environmental sanitation, living conditions, and land quality assessment. After a large amount of land is piled with construction waste, It will reduce the quality of the soil and reduce the production capacity of the soil. Therefore, it is necessary to carry out related treatment of construction waste, in which waste construction concrete and waste bricks are crushed to produce coarse and fine aggregates, which can be used to produce concrete, mortar or preparation of corresponding strength levels. Building materials such as blocks, wall panels, floor tiles, etc., because construction waste is piled in the open air, it is often affected by rain and becomes damp. The broken construction waste has a high water content and cannot be used, which affects the next production
