Abstract
The on-line automatic control belt conveyer of a kind of coal amount, comprise the belt transport unit be made up of belt support frame, belt backing roll, belt and drive motors, it is characterized in that: be also provided with and be arranged on below belt for the frequency converter taking the electronic scale of coal weight on belt, PLC control module in real time and electrically connect with drive motors, the weight of material data collected are inputed to PLC control module by electronic scale, the control signal of PLC control module inputs to frequency converter, realizes the control to drive motors by frequency converter.This equipment can regulate belt speed automatically according to coal amount size, can not only greatly increase work efficiency, and can also avoid the improper potential safety hazard brought of hand fit.
Description
Technical field
The utility model belongs to belt conveyer material transportation field, is specifically related to the on-line automatic control belt conveyer of a kind of coal amount.
Background technology
At present, in the industry such as coal, coking of coal, use the utilization rate of belt conveyer convey materials very large, but due to Material control can not be very accurate, belt transporter launder can be caused to block; Particularly transport coal belt under tank, instantaneous coal amount is 2 ~ 3 times of specified coal amount sometimes, if workman finds not in time, causes chute blocking, belt tearing, carrys out major safety risks to belt conveyer fortune ribbing.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model provides a kind of coal amount on-line automatic control belt conveyer, this equipment can regulate belt speed automatically according to coal amount size, can not only greatly increase work efficiency, and can also avoid the improper potential safety hazard brought of hand fit.
The technical scheme that the utility model adopts is: the on-line automatic control belt conveyer of a kind of coal amount, comprise the belt transport unit be made up of belt support frame, belt backing roll, belt and drive motors, also be provided with and be arranged on below belt for the frequency converter taking the electronic scale of coal weight on belt, PLC control module in real time and electrically connect with drive motors, the weight of material data collected are inputed to PLC control module by electronic scale, the control signal of PLC control module inputs to frequency converter, realizes the control to drive motors by frequency converter.
Further optimization, in described PLC control module, setting one is about the limit value of weight of material on belt, under the state that the numerical value received is greater than setting value, PLC control module exports control signal to frequency converter, by the corresponding speed of service of frequency converter adjustment drive motors.
The beneficial effects of the utility model are:
The utility model is by the electronic scale on belt feeder, control the output frequency of frequency converter, realize the supply of material on belt, make whole process not need to want manual operation automatically to complete, not only substantially increase operating efficiency, also avoid the improper potential safety hazard brought of hand fit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1, belt support frame, 2, belt backing roll, 3, belt, 4, drive motors, 5, electronic scale, 6, PLC control module, 7, frequency converter.
Detailed description of the invention
Elaborate to embodiment of the present utility model below in conjunction with accompanying drawing, the present embodiment, premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in the figure, the on-line automatic control belt conveyer of a kind of coal amount, comprise by belt support frame 1, belt backing roll 2, the belt transport unit that belt 3 and drive motors 4 are formed, belt transport unit as herein described is the technology of existing maturation, also be provided with and be arranged on below belt 3 for taking the electronic scale 5 of coal weight on belt in real time, PLC control module 6 and the frequency converter 7 electrically connected with drive motors 4, the weight of material data collected are inputed to PLC control module 6 by electronic scale 5, the control signal of PLC control module 6 inputs to frequency converter 7, the control to drive motors 4 is realized by frequency converter 7.
Further explanation the technical program, in described PLC control module 6, setting one is in advance about the limit value of weight of material on belt, under the state that the numerical value received is greater than setting value, PLC control module 6 exports control signal to frequency converter 7, adjusts the corresponding speed of service of drive motors 4 by frequency converter 7.
Operation principle of the present utility model is as follows: by by electronic technology with automatically control to combine, electronic scale is arranged in the middle part of belt feeder for taking the weight of material on belt, PLC control module controls frequency converter output frequency after receiving signal increases or reduces, control the rotating speed of drive motors, reach the conveying capacity controlling belt conveyer.Not only substantially increase operating efficiency, also avoid the improper potential safety hazard brought of hand fit.
It is prior art that this programme does not describe technology in detail.
