Real-time sand chloride ion content monitoring device and method for concrete production line

Abstract

The invention discloses a real-time sand chloride ion content monitoring device and method for a concrete production line. The device comprises a sand taking device, a measuring device and a control device. The sand taking device is arranged at a sand feeding device for a concrete production line and directly samples from a sand feeding port for the concrete production line, a sampled sample is transmitted to the measuring device to measure the chloride ion concentration, and the control device is in communication connection with the sand taking device and the control end of the measuring device. The device and the method have the technical effects that the device can directly sample from a concrete production line and synchronously upload detection data and a monitoring picture of the whole sampling and measuring process to a management platform through a network, so that the real-time monitoring of the chloride ion content of the sand for production in a mixing plant is realized, andcounterfeiting behaviors such as sample exchange in the measuring process can also be prevented.

Description

technical field [0001] The invention relates to a real-time monitoring device and method for the chloride ion content of sand used in a concrete production line. Background technique [0002] The demand for sand and gravel resources in engineering construction is increasing day by day, while natural high-quality sand and gravel resources are increasingly depleted. The problem of sand and gravel resources for concrete has become a bottleneck restricting the sustainable development of civil engineering. Driven by economic interests, some people use extremely harmful sand and gravel resources. Sea sand replaces river sand, but sea sand is extremely harmful to engineering construction. [0003] Sea sand refers to the sandy deposits distributed in the coast and shallow sea, mainly medium-coarse sand, including some fine sand and gravel. Because sea sand contains chloride salts, it may cause corrosion of steel bars in concrete structures, thereby reducing the quality of concrete s...
