Sandstone water ratio measurement and control system and concrete production equipment comprising sandstone water ratio measurement and control system

Abstract

The invention relates to concrete production equipment, in particular to a sandstone water ratio measurement and control system. The invention aims to provide the sandstone water ratio measurement and control system which can measure and control the sandstone water ratio in different states in real time. In order to fulfill the aim, the sandstone water ratio measurement and control system provided by the invention comprises a sandstone water ratio measurement system, an analog-to-digital conversion communication system and a control system, wherein the sandstone water ratio measurement system comprises a water ratio sensor; the analog-to-digital conversion communication system comprises an input / output (I / O) module, an analog quantity module and a communication module connected in order; the water ratio sensor is connected with the I / O module through a connecting cable; and the control system is connected with the communication module through a communication cable. The sandstone water ratio measurement and control system is high in intelligence degree and quick in response, the measured data is reliable, manual intervention is less when the system is used, the current weighing is automatically intervened by the system, and the measured numerical value is accurate.

Description

technical field [0001] The invention relates to concrete production equipment, in particular to a sand and gravel moisture content measurement and control system. Background technique [0002] Concrete is currently the most widely used material in construction and other fields. Different uses of concrete have different formulations. In order to produce concrete that meets the requirements, various raw materials should be accurately measured during the measurement process. In the actual production process, a large amount of sand is used, but it is generally stacked in the open air, and the weather or site has a great influence on the moisture content of these materials, and in the same pile of materials, the moisture content of the materials at the top and bottom ends It is also different, so it is difficult to strictly control the moisture content of concrete in the process of concrete production. At present, the practice of concrete manufacturers is to measure certain san...

AI Technical Summary

Problems solved by technology

The method of manually measuring the moisture content of raw materials is time-consuming and laborious, and it involves a lot of human factors. The moisture content of sand and gravel is often considered as a fixed value. The measured value has a lot to do with the raw materials obtained. Directly affect the quality of concrete
