Description
Technical field
The present invention relates to the lime production line cooler fan automatic control device of a kind of rotary kiln, it is possible to achieve regulate cooler drop temperature arbitrarily in real time according to manufacturing technique requirent.
Background technology
At present, in rotary kiln white lime production technology, cooler drop temperature is operated by personnel's manual adjustments cooling fan flow air door and realizes.Shortcoming: labor intensity is big, not energy-conservation (blower motor is constantly in rated operation), it is impossible to regulate air quantity according to technological requirement in real time, drop temperature is high, often results in finished belt and burns phenomenon.
Summary of the invention
In order to overcome the shortcoming of prior art, the present invention provides the cooler fan automatic control device of a kind of lime production line.It can be automatically adjusted cooler rotation speed of fan in real time according to technological requirement, it is ensured that drop temperature is in the reasonable scope, cooler blower fan working stability, reliable.
This invention address that its technical problem is adopted the technical scheme that, it includes:
Industrial computer: be arranged on the operating board of control room, it is connected with the Programmable Logic Controller in regulator cubicle by EPA, display cooler head temperature, four discharge bucket temperature, the real-time air quantity of blower fan, and according to producing the cooler drop temperature being actually needed setting.
And regulator cubicle: regulator cubicle is provided with air switch, catalyst, input reactance device, cooler fan frequency converter, Programmable Logic Controller and input thereof and output interface, the input interface of described PLC connects chiller temperature detection thermocouple and cooler fan delivery cut-off equipment respectively, the output interface of PLC connects cooler by Profibus-DP fieldbus and drives converter, and cooler drives Frequency Converter Control cooler blower motor.
The present invention can be automatically adjusted cooler rotation speed of fan in real time according to technological requirement, it is ensured that drop temperature is in the reasonable scope, cooler blower fan working stability, reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Accompanying drawing is block chart of the present invention.
Detailed description of the invention
As shown in drawings, the present invention includes industrial computer and regulator cubicle.
Described industrial computer is arranged on the operating board of control room, it is connected with the Programmable Logic Controller (PLC) in regulator cubicle by EPA, display cooler head temperature, four discharge bucket temperature, the real-time air quantity of blower fan, and it is actually needed setting cooler drop temperature according to production.
Described regulator cubicle is provided with air switch, catalyst, input reactance device, cooler fan frequency converter, Programmable Logic Controller (PLC) and input thereof and output interface, the input interface of described PLC connects chiller temperature detection thermocouple and cooler fan delivery cut-off equipment respectively, the output interface of PLC connects cooler by Profibus-DP fieldbus and drives converter, and cooler drives Frequency Converter Control cooler blower motor.
Described chiller temperature detection thermocouple is used for detecting cooler upper feeding temperature and cooler outlet drop temperature, provides rotation speed of fan to regulate parameter for PLC system.
Described fan delivery detection cut-off equipment is used for detecting fan delivery, provides rotation speed of fan to regulate parameter for PLC system.
Described PLC adopts the S7-300 of Siemens Company.Described cooler fan frequency converter adopts the digital AC converter of 6ES70 of Siemens Company.
According to production requirement, industrial computer sets cooler drop temperature, chiller temperature detection thermocouple output signal enters PLC system, in PLC system, computing draws real time temperature, simultaneously compressor flow signals collecting enter PLC system normalized after, a parameter as rotation speed of fan regulated quantity participates in calculating, and calculated results is transferred to rotation speed of fan adjustment converter by Profibus-DP fieldbus, regulate air quantity, make drop temperature meet setting requirement.It is regulate output in real time according to production requirement owing to rotation speed of fan regulates converter, therefore by the method can significantly improve work efficiency, improves product quality, reduce production cost and labor intensity.
