Problems solved by technology

The water washing method consumes a lot of water resources, and the subsequent wastewater treatment is difficult, and direct discharge will cause water pollution
The mechanical sieve separation method has problems such as low efficiency, serious screen wear, high energy consumption and unclean separation.
The above two methods also have the problems of poor working environment and poor working conditions (such as mud, dust, etc.)

Abstract

The invention discloses an efficient dedusting separator of building man-made sand, comprising a housing. A rotary scatterer plate and a sand collecting hopper are arranged inside the housing sequentially from top to bottom. The housing is provided with a feed passage between the scatterer plate and the sand collecting hopper. The housing is further provided with a finished sand discharge passage connected to the bottom of the sand collecting hopper. A sorting unit is arranged at the top of the housing. A bag collector and a fan are arranged outside the housing. An inlet of the bag collector is connected to an air outlet of the sorting unit through a first pipeline. An air inlet of the fan is connected to an outlet of the bag collector through a second pipeline. The bag collector is provided with a sand collection point. The efficient dedusting separator of building man-made sand requires no water resources, is low in energy consumption, free of dust pollution, free of mesh abrasion and high in separation efficiency and allows work environment to be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of machine-made sand separation, in particular to a high-efficiency powder removal and separation device for machine-made sand used in construction. Background technique [0002] The existing machine-made sand used in construction should meet the national standard GB / T14684-2001 "Sand for Construction". Sand: 2.2 to 1.6. In the actual production process, the primary machine-made sand contains a large amount of fine stone powder and mud powder less than 600μm, and its content in the standard should meet the following table; [0003] Limits of mud content and stone powder content in machine-made sand [0004] [0005] The traditional method of removing mud and fine stone powder is water washing or mechanical sieving separation, and the combination of the two methods. The water washing method consumes a large amount of water resources, and the subsequent wastewater treatment is relatively difficult, and d...
