Embodiment
Below in conjunction with accompanying drawing content of the present invention is described, following description only is exemplary and indicative, should any restriction not arranged to protection scope of the present invention.
Please referring to Fig. 1, Fig. 1 is the process flow diagram of a kind of embodiment of the method for cement content in the detection stirring host provided by the present invention.
As shown in Figure 1, the method for cement content in the detection stirring host provided by the invention is used to detect whether cement lacks in the stirring host, and this method specifically may further comprise the steps.
Step S101 is in the resistance that material brought under the stirring in the detection stirring host.In the concrete scheme; Force transducer can be set in stirring host; Stirring host in the course of the work; The paddle wheel band material and is rotated along certain orientation, and force transducer can detect in the stirring host at mixing direction or against mixing direction and be in the resistance that material brought under the stirring, and sends resistance signal.
Step S102 compares resistance that is detected and preset range of resistance, if the resistance that is detected, judges then that cement content is less than standard content in the stirring host less than said preset range of resistance; If the resistance that is detected in said preset range of resistance, judges then that cement content meets the requirements in the stirring host; If the resistance that is detected greater than preset range of resistance, is then judged cement content overgauge content in the stirring host.
Cement-free is arranged in the concrete, and concrete denseness will have very big variation, and the resistance that the material in the stirring host brings along with the difference of denseness also will be very different; And the proportioning of every kind of its various materials of model concrete is certain; Its density and denseness also are certain, and the resistance that in stirring host, is brought also is certain, and the range of resistance that the concrete various materials that can demarcate the standard proportioning are in advance brought when in stirring host, stirring is for presetting range of resistance; Can detect cement content and be the resistance that the concrete of standard proportioning is brought in whipping process; This resistance is the standard resistance value, can this standard resistance value defined be preset range of resistance, in the preferred version; Consider the influence of impacting in the concrete whipping process, this preset range of resistance can have the range of resistance of the scope that necessarily fluctuates for size.
Detect resistance and preset range of resistance compares with above-mentioned; If the resistance that is detected is less than said preset range of resistance; The denseness that material in the stirring host is described is lower; Then judge in the stirring host cement content less than standard content, do not add cement in the stirring host or the amount of the cement that added less; If the resistance that is detected in said preset range of resistance, judges then that cement content meets the requirements in the stirring host; If the resistance that is detected greater than preset range of resistance, is then judged cement content overgauge content in the stirring host.
Method through cement content in the above-mentioned detection stirring host; Can accurately detect and whether lack cement; The influence of the vibration that this method does not receive to be produced in the stirring host course of work; The detection degree of accuracy is higher, can improve the quality that concrete becomes to produce, and can reduce owing to lack cement, concrete and not solidify the accident resulting from poor quality of projects that causes.
In the preferred version; If the resistance that detected, is then judged the interior cement content of stirring host less than preset range of resistance less than standard content, and send cement and lack alarm signal; Cement lacks in the concrete in the alert stirring host, should stop production or suspend discharging to haulage vehicle.
In the preferred version; If the resistance that is detected is greater than said preset range of resistance; Then judge cement content overgauge content in the stirring host; And sending the cement alarm signal that exceeds standard, cement amount is too much in the concrete in the alert stirring host, should stop to produce or suspends discharging to haulage vehicle.
In the more excellent scheme,, after step S102, also can comprise step S103 in order to detect the accurate content of cement in the stirring host.
Step S103 according to the pairing Resistance Value of demarcating in advance of different water cement content, confirms and the corresponding cement content of resistance that is detected.
In the concrete scheme; The resistance that concrete brought of different content cement is different; Can detect the size of the resistance that the concrete that contains different content cement brings in advance in whipping process; What demarcate the corresponding Resistance Value of different water cement content institute is different standard values, and detected in the course of the work resistance of stirring host and corresponding standard value compare, can obtain and the resistance that detected with respect to cement content.This scheme can accurately detect the content of cement in the stirring host; When if the cement of stirring host lacks, can calculate the amount that lacks cement in the stirring host according to the cement water yield in the determined stirring host; To stirring host add exposed cement, make the cement content conformance with standard; Equally,, can calculate the amount that needs to mend rest materials, correspondingly add the amount of corresponding rest materials, so that obtain the concrete of standard if in the stirring host during cement content overgauge content.
