System for reducing content of dust in air of sand and gravel production line

Abstract

The invention relates to building material production equipment, and provides a system for reducing the content of dust in air of a sand and gravel production line. The system comprises a dust removing machine, a liquid spraying device, a dust collecting pipeline, a dust concentration sensor and a PLC, the dust removing machine comprises a dust blower and a vacuum cleaner, the dust blower and thevacuum cleaner are arranged at the dust generating positions of the sand and gravel production line, the arrangement positions of an air blowing opening of the dust blower and a dust suction opening of the vacuum cleaner are in the opposite direction, the dust collecting pipeline is connected with the tail part of the vacuum cleaner, the liquid spraying device is arranged at the rear end of the dust removing machine of forward flow of a conveyor of the sand and gravel production line, and the PLC is connected with the dust removing machine and the liquid spraying device. The system provided bythe invention has the beneficial effects of reducing the amount of the dust in the production environment of the sand and gravel production line and protecting a production device and the respiratoryhealth of sand and gravel production personnel.

Description

technical field [0001] The invention relates to building material production equipment, in particular to dust suppression equipment for a gravel production line. Background technique [0002] With the progress of modern urbanization, sand and gravel have become the necessary building materials in our construction projects. The common sand and gravel production line will produce a lot of dust during the production process, which will cause a lot of inconvenience for the construction workers, affect the air environment around the sand and gravel production line, and bring human respiratory diseases; at the same time, the long-term operation of the sand and gravel production line will cause some mechanical Or piles are formed on the road for transporting sand and gravel, which leads to failure of sand and gravel production equipment and inconvenient transportation of transport tools for transporting sand and gravel. [0003] In CN106140432A, a sand screening device is disclose...
