The cooler fan automatic control device comprises an industrial control computer and an electrical cabinet, wherein the industrial control computer is arranged on an operating platform of a control room, is connected with a programmable logic controller (PLC) in the electrical cabinet by an industrial Ethernet, and is used for displaying the top temperature of the cooler, the temperature of four outlet hoppers and the real-time air quantity of a fan, and setting the discharge temperature of the cooler according to the actual demand of production; the electrical cabinet is internally provided with an air switch, a contactor, an input reactor, a cooler fan frequency converter, the PLC, and an input interface and an output interface of the PLC, wherein the input interface of the PLC is respectively connected with a temperature detection thermoelectric couple of the cooler and an air quantity interception device of the cooler fan; the output interface of the PLC is connected with the cooler driving frequency converter by a Profibus-DP field bus; and the cooler driving frequency converter is used for controlling a motor of the cooler fan.
Description
Technical field
The utility model relates to a kind of lime production line cooler draught fan automatic control device of rotary kiln, can realize according to any real-time regulated cooler of manufacturing technique requirent drop temperature.
Background technique
At present, in the rotary kiln lime production technology, the cooler drop temperature is realized by operator's manual tune cooling fan flow air door.Shortcoming: labor intensity is big, and not energy-conservation (fan motor is in the nominal operation state always) can not be according to technological requirement real-time regulated air quantity, and the drop temperature height often causes finished belt to burn phenomenon.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of cooler draught fan automatic control device of lime production line.It can regulate the cooler rotation speed of fan in real time automatically according to technological requirement, guarantees drop temperature in the reasonable scope, cooler blower fan working stability, reliable.
The technical scheme in the invention for solving the technical problem is that it comprises:
Industrial computer: be installed on the operating table in control room, be connected with programmable controller in the regulator cubicle by EPA, show cooler head temperature, four discharging bucket temperature, the real-time air quantity of blower fan, and according to producing the cooler drop temperature that actual demand is set;
And regulator cubicle: air-break switch, contactor, input reactance device, cooler fan frequency converter, programmable controller and input and output interface thereof are installed in the regulator cubicle, the input interface of described PLC connects chiller temperature respectively and detects thermocouple and cooler fan delivery cut-off device, the output interface of PLC connects cooler by the Profibus-DP Field bus and drives frequency variator, and cooler drives Frequency Converter Control cooler fan motor.
The utility model can be regulated the cooler rotation speed of fan in real time automatically according to technological requirement, guarantees drop temperature in the reasonable scope, cooler blower fan working stability, reliable.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model Block Diagram.
Embodiment
As shown in drawings, the utility model comprises industrial computer and regulator cubicle.
Described industrial computer is installed on the operating table in control room, be connected with programmable controller (PLC) in the regulator cubicle by EPA, show cooler head temperature, four discharging bucket temperature, the real-time air quantity of blower fan, and set the cooler drop temperature according to producing actual demand.
Air-break switch, contactor, input reactance device, cooler fan frequency converter, programmable controller (PLC) and input and output interface thereof are installed in the described regulator cubicle, the input interface of described PLC connects chiller temperature respectively and detects thermocouple and cooler fan delivery cut-off device, the output interface of PLC connects cooler by the Profibus-DP Field bus and drives frequency variator, and cooler drives Frequency Converter Control cooler fan motor.
Described chiller temperature detects thermocouple and is used to detect cooler top pan feeding temperature and cooler outlet drop temperature, regulates parameter for the PLC system provides rotation speed of fan.
Described fan delivery detects cut-off device and is used to detect fan delivery, regulates parameter for the PLC system provides rotation speed of fan.
Described PLC adopts the S7-300 of SIEMENS.Described cooler fan frequency converter adopts the digital AC converter of 6ES70 of SIEMENS.
According to production requirement, on industrial computer, set the cooler drop temperature, chiller temperature detects thermocouple output signal and enters the PLC system, computing draws real time temperature in the PLC system, the compressor flow signals collecting enters the PLC system after standardization simultaneously, calculates as a parameter participation of rotation speed of fan regulated quantity, and gained result of calculation is transferred to rotation speed of fan by the Profibus-DP Field bus and regulates frequency variator, regulate air quantity, make drop temperature meet the setting requirement.Because it is according to production requirement real-time regulated output power that rotation speed of fan is regulated frequency variator, so can significantly improve working efficiency by the utility model, improves the quality of products, and reduces production costs and labor intensity.
