Background technology
Disk feeder uses electrical motor to drive disk through coupler by reductor at present.When disk rotated, the material in the feed bin was along with disk is mobile together, and moved to a side of discharging opening, discharged material through gate or scraper.The size of discharge rate can be regulated with doctor blade device or gate.Because the size of discharge rate is regulated with doctor blade device or gate, exists the feeding coal precision little, poor controllability, ineffective shortcoming.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of disk feeder speed control unit, its reliable operation, steady quality, efficient is high.
The present invention solves the technical scheme that its technical matters takes:
Industrial computer: be installed on the operator's station of control cabin, be connected with Programmable Logic Controller in the regulator cubicle by the Internet net;
Regulator cubicle: air switch, contactless switch, input reactance device, the first frequency converter, the second frequency converter, Programmable Logic Controller and input thereof, output interface are installed in the regulator cubicle, the input interface of described Programmable Logic Controller connects respectively proportioning belt instant flow rate scale, the output interface of Programmable Logic Controller connects the second frequency converter by the Profbus-DP fieldbus, Programmable Logic Controller carries out computing to actual blanking instant flow rate and actual setpoint difference, controls the speed of disk feeder as setting value; The sensor that is electrically connected with the first frequency converter is coaxial fixing with disk feeder;
Panel block: starting and stopping button, speed adjusting resistance and frequency meter are installed on the panel block, the starting and stopping button is used for controlling the operation of frequency converter, speed adjusting resistance is connected with the dynamo-electric machine of chain grate, but the speed of manual regulation disk feeder, frequency meter is connected with the disc feeding motor, shows the actual frequency of disc feeding motor.
Reliable operation of the present invention, steady quality, efficient is high.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes industrial computer 1, regulator cubicle, panel block and proportioning belt 2.
