Embodiment Construction

[0019] The technical solution of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0020] see figure 1 , the present invention is based on particle friction machine-made sand production quality information monitoring system is set on the machine-made sand belt conveyor, the machine-made sand enters the mixer (2) through the feed port (1), sampling 30kg per batch, and the mixing time is 60s . After the stirring is completed, the sampler (3) is opened, and the machine-made sand enters the scale (5) through the sampler (3). The volume of the scale (5) is 6L, and the maximum value is 20kg. Stack tall into a cone shape. The automatic scraping device (4) drives the scraping ruler to swing through the shaft arm, scraping and leveling the machine-made sand higher than the measuring scale (5). Measuring scale (5) automatically obtains the internal machine-made sand quality M 1 And the data...

Abstract

The invention discloses a manufactured sand production quality informatization monitoring system based on grain friction. The manufactured sand production quality informatization monitoring system isformed by seven portions including a sampling module, a screening module, a morphology analysis module, a grading analysis module, a data processing and information uploading module, a remaining material recovery module and a dedusting module. By adopting the system, the fineness modulus, the stone powder content, the outflow time and the clearance rate of manufactured sand can be monitored in real time, key technical indexes including the outflow time and the clearance rate of specific particle-size manufactured sand can also be monitored, functions of real-time online monitoring and ultra-limit alarm of the quality of the manufactured sand in a production process are realized, and timely effective criteria can be provided for production quality control of the manufactured sand.

Description

technical field [0001] The invention belongs to the technical field of machine-made sand preparation, and in particular relates to an informational monitoring system for machine-made sand production quality based on particle friction. Background technique [0002] Manufactured sand refers to rocks, mine tailings or industrial waste particles with a particle size of less than 4.75mm that are made by mechanical crushing and screening after soil removal. With the rapid development of my country's infrastructure construction and the increasing emphasis on the ecological environment, there are fewer and fewer natural sand resources that can be mined and utilized. Machine-made sand instead of river sand to prepare concrete has become an indicator for improving the greenness of concrete and realizing sustainable development of the concrete industry. inevitable trend. [0003] The machine-made sand production line is usually composed of feeders, crushers, sand making machines, vibra...
