Abstract

The invention discloses a pneumatic control system of a machine-made sand making device. The pneumatic control system comprises an air compressor, a gas storage tank connected to the air compressor, a main pipe filter connected to the gas storage tank, a forth filter pressure reducing valve connected to the main pipe filter, a pulse valve and a lifting valve for controlling dedusting of a dust remover, wherein the pulse valve and the lifting valve are respectively connected to an outlet of the forth filter pressure reducing valve, a first solenoid valve connected to the main pipe filter and used for controlling discharge of a powder tank, a second solenoid valve connected to the main pipe filter and used for controlling opening and closing of a blowing device for removing dust in a coarse material recovery pipe, and PLC connected to a control end of the air compressor, wherein the PLC has an output end respectively connected to the pulse valve, the first solenoid valve and the second solenoid valve. The dust remover, the powder tank and the coarse material recovery pipe share a gas source and assembling and control are convenient.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an air control system for machine-made sand equipment. Background technique [0002] With the continuous development of the construction industry, people's attention to sand and gravel aggregates has gradually increased, and the importance of machine-made sand and gravel aggregates has also become more prominent. However, in the process of aggregate production, a large amount of dust will inevitably be generated. The traditional machine-made sand system only takes partial dust removal or does not take dust removal measures. [0003] At present, the air control system of the machine-made sand equipment with dust removal function has multiple air sources, which is inconvenient to assemble and control, and the dust return pipeline needs to be manually cleaned off-line, which is low in efficiency and requires a lot of maintenance. At the same time, the filtering effect ...
