Abstract
The invention belongs to a road face construction machinery, which relates to a control system of an asphalt concrete mixing device, in particular to a cold feed speed adaptive control system of the asphalt concrete mixing device. The cold feed speed adaptive control system of the asphalt concrete mixing device comprises a material level device which is arranged at the bin of the mixing device and is used for obtaining a material level height signal, the signal output part of the material level device is connected with the signal input terminal of a transmitter, the signal output terminal of the transmitter transmits the material level height signal to an industrial control computer, the industrial control computer sends a control instruction signal to the analog current frequency instruction input terminal of a converter, the converter is connected with the speed control circuit of a cold feed motor. The cold feed speed adaptive control system can make a real-time adaptive control on the speed of the cold feed motor according to the material level of the bin of the mixing device, thus the continuous and even feed is ensured, the material overflow is reduced, the energy consumption is lowered, and the ingredient quality is ensured.
Description
Technical field
The invention belongs to field of road engineering machinery, relate to a kind of control system of asphalt mixing plant, specifically is a kind of cold delivery rate self-adaptive control system for asphalt mixing plant.
Background technology
When existing asphalt mixing plant carries out the material stirring, generally to add multiple aggregate, for guaranteeing adding of various aggregates according to special ratios, need control interpolation speed, in traditional equipment, adopt manually of cold delivery rate control controlled more, complex operation not only, also cause waiting phenomenons such as material, flash, cause productivity ratio reduction, energy waste, proportioning accuracy also can not get guaranteeing.
Summary of the invention
Technical problem to be solved by this invention is, providing a kind of can monitor in real time to the mixing plant feed bin, and the cold delivery rate self-adaptive control system for asphalt mixing plant that cold delivery rate is controlled automatically, with reach feed continuously, reduce the purpose of flash, energy savings, assurance batching quality.
Cold delivery rate self-adaptive control system for asphalt mixing plant of the present invention includes and is installed in the level detector that mixing plant feed bin place is used for obtaining the controlling level signal, the segment signal output of level detector is connected with the signal input part of a transmitter, the signal output part of transmitter is delivered to an industrial control computer with the controlling level signal, industrial control computer is delivered to the analog current frequency instruction input of a frequency converter with the control instruction signal, and frequency converter is connected in the cold feed rotating speed of motor control circuit.
The aanalogvoltage frequency instruction input of described change device also is connected with a potentiometer R1, is used for frequency converter frequency is manually controlled.
The present invention can carry out Self Adaptive Control to cold feed rotating speed of motor in real time according to the material level of mixing plant feed bin, thereby has guaranteed continuously, feed equably, has reduced flash, has reduced energy consumption, has guaranteed the batching quality.
Description of drawings
Fig. 1 is the circuit theory diagrams of the embodiment of the invention.
The specific embodiment
As shown in the figure, in the course of work of the present invention, the 1 pair of material level of level detector that is installed in the feed bin place is monitored, and the controlling level signal transferred to transmitter 2 by holding wire, the signal that transmitter receives the continous way level detector send into standard signal with its amplification change, and be sent to industrial control computer 3 and handle, after industrial control computer is handled according to the program of presetting, analog current frequency instruction input transmission frequency control signal to frequency converter 4, frequency converter is according to this control signal control batcher motor speed, thus the control of realization cold delivery rate self-adaptive.Also can as required frequency converter be set at manual control, at this moment, manually control feed motor delivery rate by the potentiometer R1 that is connected aanalogvoltage frequency instruction input.Frequency converter of the present invention can adopt the VFD-M Series Frequency Converter, and the frequency converter model in the present embodiment is VFD015 M 43A.
