Novel energy-saving artificial sandstone winnowing and powder removing machine with wind power recycling function

Abstract

The invention discloses a novel energy-saving artificial sandstone winnowing and powder removing machine with a wind power recycling function, and relates to the technical field of sandstone powder removing, the novel energy-saving artificial sandstone winnowing and powder removing machine comprises a feeding assembly, a primary winnowing assembly, a secondary winnowing assembly, a separating assembly and a mounting rack, and the feeding assembly, the primary winnowing assembly, the secondary winnowing assembly, the separating assembly and the mounting rack are fixedly connected; the feeding assembly is connected with the primary winnowing assembly, the primary winnowing assembly is connected with the secondary winnowing assembly and the separation assembly, and the separation assembly is connected with the secondary winnowing assembly. The feeding assembly inputs gravel, the primary winnowing component and the secondary winnowing component remove stone powder, the separating component separates soil and the stone powder in airflow, and the separated airflow is recycled. According to the separation assembly, the stone powder is completely separated from the air flow, the medium-particle gravel is independently collected and used for gap filling of concrete, and the air flow completely separating the stone powder can be recycled.

Description

technical field [0001] The invention relates to the technical field of sand and gravel de-powdering, in particular to a novel energy-saving artificial sand and gravel wind-separation and de-powdering machine with wind power recycling. Background technique [0002] Artificial sand is obtained by impact crushing of pebbles dug out of mountains and rivers. The sand and gravel produced in this way have more stone powder and need to be de-pulverized before being used. At present, the most mainstream sand and gravel powder removal method is wind separation and powder removal, but the conventional wind separation powder removal device has many defects and cannot be used. [0003] Conventional air separation and de-powdering machine cannot realize the recycling of air flow, on the one hand, it will cause waste of resources, and on the other hand, the discharge of stone powder will also cause environmental pollution. There are many soil particles mixed in artificial sand and gravel....

AI Technical Summary

Problems solved by technology

At present, the most mainstream way of removing powder from sand and gravel is wind separation, but the conventional wind separation device has many defects and cannot meet the needs of the users.

[0003] Conventional winnowing and de-powdering machines cannot realize the recycling of air flow, on the one hand, it will cause waste of resources, on the other hand, the discharge of stone powder will also cause environmental pollution

The artificial sand is mixed with many soil particles. These soil particles are large and small. Conventional winnowing equipment cannot effectively separate the soil particles from the sand and gravel, which will lead to a decrease in the strength of the concrete made of sand and gravel. , affecting subsequent use

[0004] The wind power setting of conventional winnowing powder removal is inaccurate. Sand and gravel of different sizes are mixed together, and it is easy to block each other between sand and gravel, which reduces the effect of winnowing. The wind power of winnowing selection cannot adapt to sand and gravel of different sizes , it is easy to make mistakes in the winnowing intensity, resulting in sand and gravel being removed as stone powder, or stone powder being left as sand and gravel
