Sand and stone separator

Abstract

The invention discloses a sand and stone separator. The sand and stone separator comprises a roller washing and screening machine cylinder, a roller washing and screening machine frame and a sand spiral dehydrator; the roller washing and screening machine cylinder is placed on the roller washing and screening machine frame; and the sand spiral dehydrator is placed below the roller washing and screening machine frame. The sand and stone separator adopts a separate design of sand and stone screening and sand dehydration; the sand and stone screening adopts a two-stage mechanism; firstly, concrete is screened after rolling and cleaning; and a high-pressure cleaning device is arranged on a screen, so that the sand and stone separation is more thorough and cleaner. The cleaning part volume of the roller washing and screening machine cylinder is high, so that the instant high-flow impact of sand and stone starch solution can be stopped; and after the separation work is finished, the starch solution in the sand and stone separator is totally rotated out without residues, so that such problems as internal caking, blockage and corrosion are preferably solved. The sand and stone separator is simple in structure, fewer in wear parts, free of maintenance at ordinary times, long in equipment service life and simple in maintenance.

Description

technical field [0001] The invention relates to the field of separators, in particular to a sand and gravel separator. Background technique [0002] At present, most of the sand and gravel separators in the domestic market adopt the integrated design of sand screening and sand dewatering. The sand, gravel and slurry water directly enter the screening cylinder. Due to the high viscosity of the slurry water, the separation of sand, stone and cement slurry water is not enough. Thoroughly; after separation, there is still a large amount of high-viscosity and corrosive slurry in the equipment, which is easy to agglomerate, block and corrode; the structure is too compact and complicated, the components are severely worn, the service life is short, and the maintenance and repair workload is heavy. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a two-stage mechanism for sand and gravel screening. Firs...
