Cement supply online calibration system of stable soil plant mix equipment

Abstract

The invention discloses a cement supply online calibration system of stable soil plant mix equipment, comprising an inclined frequency-conversion spiral feeder, a calibration bin, a detection unit 1, a detection unit 2 and a control system, wherein the detection unit 1 and the detection unit 2 are both connected with the control system. The calibration bin is fixed at the upper part of the inclined frequency-conversion spiral feeder and used for temporarily storing and buffering supplied cement to prevent the cement from directly impacting the inclined frequency-conversion spiral feeder; the detection unit 1 is used for detecting the change value Q1 of cement weight in the calibration bin before and after the calibration; the detection unit 2 is used for detecting the instant cement flow value of a discharging hole of the inclined frequency-conversion spiral feeder; and the control system is used for correspondingly controlling the rotate speed of the inclined frequency-conversion spiral feeder according to calibration coefficient obtained from real-time analysis and processing. The invention has reasonable design, simple and convenient operation and high calibration precision, and can overcome the defect that the cement calibration of prior stable soil plant mix equipment is achieved only by manpower, is difficult to operation and has low calibration precision.

Description

technical field [0001] The invention relates to the technical field of on-line calibration structure configuration and on-line monitoring of a cement supply system for stabilized soil plant mixing equipment, in particular to an online calibration system for cement supply of stabilized soil plant mixing equipment. Background technique [0002] Stabilized soil plant mixing equipment is the key equipment for mixing stabilized soil. It is used for mixing various stabilized mixtures with hydraulic materials as binders, and uniformly mixes aggregates, binders, water and other materials according to the construction mix ratio. The accuracy of the cement dosage of the stabilized soil plant mixing equipment is determined by the cement measurement accuracy, and the cement measurement accuracy depends on the correct and reasonable calibration. [0003] At present, the calibration of the cement supply system of the existing stabilized soil plant mixing equipment is generally completed b...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an on-line calibration system for cement supply of stabilized soil mixing equipment in view of the above-mentioned deficiencies in the prior art. The cement calibration of factory mixing equipment is limited to manual calibration, which is difficult to operate and has the disadvantages of low calibration accuracy
