Abstract
The utility model discloses a concrete slump on-line monitoring system. The concrete slump on-line monitoring system comprises a current sensor, a signal converting device, a PLC (Programmable Logic Controller) and a display terminal, wherein the current sensor for monitoring a current signal automatically is arranged in a stirring motor; the current sensor is connected with the signal converting device to convert the current signal into a digital signal; the signal converting device is connected with the PLC which can identify the digital signal and is used for converting the digital signal to a concrete slump value through a formula in the PLC controller; and the display terminal is connected with the PLC and is used for displaying the concrete slump value calculated by the PLC. The concrete slump on-line monitoring system, disclosed by the utility model, avoids the problems of invalidation of dust removal, dust exceeding standard and damage of dust cleaning device as the time is controlled inappropriately, and the dust cleaning device is turned on too short, too long or is not started in time in an manual operation.
Description
Technical field
The utility model belongs to the concrete batch plant field, particularly the system of monitoring slump in the whipping process.
Background technology
In engineering construction, for the quality that guarantees to construct adheres to specification, must monitor concrete technical indicator, comprising concrete slump, produce like the too high discharging opening congestion affects that causes easily of slump, like the too low construction requirement that do not reach of slump.The factor that influences slump is a lot; Like the water in the concrete formulation; The ratio of water generally is to decide by the theoretical value of sandstone water percentage in the prescription, but water percentage is changeable in actual mechanical process, and ratio early, middle and late in a day just has deviation; And the top sub-material is bigger with following part difference, and therefore concrete slump fluctuates with regard to existing.
In order to improve the stability of product slump, abroad adopt the useful water percentage detector of sandstone in early days, this kind equipment price costliness, and damaging is easily safeguarded, cost of upkeep is high, the cycle is long.The general employing of at present domestic method to the slump monitoring got the material test; Promptly when material stirs concrete material, with the naked eye observe and judging or with equipment such as concrete comprehensive testers; But adopt to get and expect that the hysteresis deviation all can appear adjusting in test; Cannot in time adjust influences product quality, and the use of can not constructing at the scene.
The utility model content
In order to address the above problem, the utility model provides the slump on-line monitoring system, it is characterized in that: comprise current sensor, signal converter device, PLC controller and display terminal; The said current sensor that is used for automatic monitoring current signal is arranged in the stirring host, and this current sensor is connected with chromacoder, is used for converting current signal into digital signal; Chromacoder is connected with the PLC controller that can discern its digital signal, is used for digital signal is calculated the value that converts slump into through the formula in the PLC controller; Display terminal is connected with the PLC controller, the value of the slump that is used to show that the PLC controller calculates.
Further, said chromacoder comprises digital electronic ammeter and analog quantity load module.
Further, said digital electronic ammeter output 4-20MA signal.
The utlity model has following beneficial effect:
The slump on-line monitoring system that provides according to the utility model adopts the unlatching of automatic controlling system dust arrester and stops.Avoided improper in the manual operation, too short, the oversize or unlatching in time of failing of dust arrester opening time, and consequences such as the dedusting inefficacy, the dust that cause exceed standard, dust arrester damage because of the control time.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further detailed explanation.
Fig. 1 is the work synoptic diagram of present embodiment slump on-line monitoring system.
Fig. 2 is the synoptic diagram of the current sensor of present embodiment slump on-line monitoring system.
Embodiment
In order better to understand the technical scheme of the utility model, describe the embodiment that the utility model provides in detail below in conjunction with accompanying drawing.
With reference to Fig. 1, shown in Figure 2; The slump on-line monitoring system of the utility model; Current sensor 1 is arranged in the stirring host; This current sensor 1 is connected with digital electronic ammeter 2, and digital electronic ammeter 2 is connected with PLC controller 4 through analog module 3, and display terminal 5 is connected with PLC controller 4.
The workflow of the utility model: current sensor 1 is automatic monitoring current signal when stirring host sky machine; Automatic again monitoring current signal when stirring when feeding intake; This current signal is through digital electronic ammeter 2 conversion output 4-20MA signals; Change into the AD digital signal through analog module 3 again, digital signal obtains the slump value through 4 processing of PLC controller and parameter and database processing, again through display terminal 5 displayed values.The staff in time adjusts concrete proportioning according to the value of the slump that shows.
The above; Be merely the utility model preferred embodiment; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
Claims (3)
1. the slump on-line monitoring system is characterized in that: comprise current sensor, signal converter device, PLC controller and display terminal; The said current sensor that is used for automatic monitoring current signal is arranged in the stirring host, and this current sensor is connected with chromacoder, is used for converting current signal into digital signal; Chromacoder is connected with the PLC controller that can discern its digital signal, is used for digital signal is calculated the value that converts slump into through the formula in the PLC controller; Display terminal is connected with the PLC controller, the value of the slump that is used to show that the PLC controller calculates.
