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 a high-efficiency powder removal and separation device for machine-made sand used in construction. The feeding channel between the bulk material tray and the sand collecting hopper. The shell is also provided with a finished sand sand outlet channel connected to the bottom of the sand collecting hopper. A sorting device is installed on the top of the shell. There is a bag filter and a fan, the inlet of the bag filter is connected to the air outlet of the sorting device through the first pipeline, and the air inlet of the fan is connected to the air outlet of the bag filter through the second pipeline. At the outlet, there is a mud and sand collection point on the bag filter. The high-efficiency powder removal and separation device for machine-made sand for construction of the present invention does not need to consume water resources, has low energy consumption, no dust pollution, no screen wear, high separation efficiency, and greatly improves the working environment.

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...
