Building aggregate screening system

Abstract

The invention relates to the technical field of aggregate screening, in particular to a building aggregate screening system. The building aggregate screening system comprises an equipment rack and a plurality of screening device installed in the equipment rack, wherein each screening device comprises a material screening inner cavity located in the screening device, a bearing frame arranged on the outer edge of a cavity opening of the material screening inner cavity and a material screening net plate erected on the bearing frame, the material screening net plates are movably erected on the bearing frames, a plurality of overturning assemblies are further arranged in the equipment rack, the screening net plates and the overturning assemblies are connected and matched in a one-to-one mode, and the screening net plates take the overturning assemblies as supporting base points and turn along with the overturning assemblies, the equipment rack is further provided with a plurality of transmission assemblies, the transmission assemblies are matched with the overturning assemblies in a one-to-one mode, and the transmission assemblies drive the overturning assemblies to rotate in a reciprocating mode. The building aggregate screening system is designed to fluctuate periodically, in the whole movement process, the acceleration direction of aggregate can be changed in a clearance mode, and therefore separation of large-particle aggregate and small-particle aggregate is facilitated.

Description

technical field [0001] The invention relates to the technical field of aggregate screening, in particular to a building aggregate screening system. Background technique [0002] Coarse aggregate for general concrete mixing is divided into four grades according to particle size: extra large stone, large stone, medium stone, and small stone. The super diameter content of various aggregates; the conventional aggregate screening system is divided into first-order screening and second-order screening. The first-order screening mainly screens the mixed small and medium-sized stone aggregates After the separation, the chute connected to the screening machine is correspondingly transported to the second-stage screening to complete the separation of extra large stones from large stones, and medium stones from small stones. [0003] However, there are certain defects in the operation of the screening machine in the prior art. Some small stone aggregates bounce and fly due to the vibr...

Problems solved by technology

[0003] However, there are certain defects in the operation of the screening machine in the prior art. Some small stone aggregates bounce and fly due to the vibration of the screen, and the medium and small aggregates that bounce and fly easily follow the super large stones and large stones through the upper discharge chute.

[0004] In the existing patented technology, there is also a baffle design structure, which uses aggregate partitions as the implementation structure, but the aggregates are partitioned and placed in a relatively static accumulation state, which will greatly reduce the operating effect of aggregate screening, and is also not suitable for small and medium stone bones.
