Description
Technical field
The utility model technology relates to a kind of pulverizer automaton, belongs to the automatic control technology field.It is mainly used in the feed manufacturing machine industry.
Background technology
Pulverizer in feed industry reality used many years, can pulverize various coarse crushing materials such as corn, Chinese sorghum, rice wheat class, dregs of rice class and vinasse class etc., being one of topmost unit in the feed process, is the key factor that influences feeding quality, output, power consumption and processing cost.
Past; feed factory is to pulverizer load control manually control of employing mostly; because pulverizer operating efficiency and main frame electric current are subjected to all multifactor impacts; all can cause bigger influence as feeder rate of feeding, material properties such as moisture, fiber content and fat content etc., suction air volume and operator itself to it; it is extremely unstable work often to occur; the situation that the main frame electric current is fluctuated; when the main frame electric current is not adjusted rate of feeding greater than rated current; cause pulverizer to shut down because of overload easily even burn main motor, causing stops production waits and loses than large economy.Therefore, take place for avoiding above accident, the operative employee generally moves the pulverizer host computer control under lower electric current, and pulverizer can not reach the state of operating at full capacity, and causes pulverizer efficient low, the energy consumption height, and cost of labor is higher simultaneously.
Therefore, need provide a kind of pulverizer automaton to overcome above-mentioned defective.
Summary of the invention
The purpose of this utility model is to provide a kind of pulverizing automaton, when the host work electric current departs from the setting electric current, can make response fast, and regulate the rotating speed of variable-frequency motor automatically, the control feeding capacity is guaranteed pulverizer stable operation in setting the current error scope.
The technical solution of the utility model: pulverizer load automaton of the present utility model comprises sampling section, control section and operating part, its control section adopts the PLC Programmable Logic Controller, sampling section comprises the current transformer that is installed in pulverizer master electric motor loop, current transformer is connected with the input of ammeter, the output of ammeter is connected with PLC, and the simulation output interface of PLC is connected with the analog input interface of feeding variable-frequency motor frequency converter.
The I/O interface of described PLC is connected with touch screen.
The output of described PLC is connected with the Host Protection device with warning device.
Advantage of the present utility model: the utility model has taken into full account pulverizer various destabilizing factors in the process of pulverizing, it adopts the PLC control technology, set the pulverizer operating current according to material characteristic, detect electric current in real time and show synchronously by current transformer and ammeter, simultaneously, ammeter feeds back to the PLC controller with detected current signal, the PLC controller is controlled the variable-frequency motor rotating speed according to the output frequency size of the bias adjustment frequency converter between setting value and the value of feedback, the control feeding capacity, make pulverizer set stable operation under the electric current operating mode, thereby can improve crush efficiency, and cut down the consumption of energy, reduce cost of labor.Of the present utility model being convenient to installed, and universal performance is good, and is safe and reliable.In case accident occurs, can in time report to the police and shut down.

The specific embodiment
As Fig. 1, the utility model comprises sampling section, control section and operating part, its control section adopts the PLC Programmable Logic Controller, sampling section comprises the current transformer that is installed in pulverizer master electric motor loop, current transformer is connected with the input of ammeter, the output of ammeter is connected with PLC, and the simulation output interface of PLC is connected with the analog input interface of feeding variable-frequency motor frequency converter.Frequency converter is connected with the feeding variable-frequency motor.The I/O interface of described PLC is connected with touch screen.
The output of described PLC suddenly stops protective device with warning device and main frame and is connected.
Described frequency converter, current transformer, PLC are installed in the control, and control panel, the ammeter of touch-screen, frequency converter are installed on the control panel.
The I/O interface of described PLC controller also is connected with the Host Protection device with warning device.In case accident occurs, can in time report to the police and shut down.
When control device of the present utility model is worked, at first, set pulverizer operating current parameter, and carry out the current parameters collection by touch-screen input manufacturing parameter.In a processing cycle, at first the current signal that is collected by current transformer passes to ammeter, and ammeter shows electric current in real time, with and pass to PLC, finish the collecting work of basic data.
After finishing the current parameters collection, by PLC parameter is handled, at first will collect current signal and handle by calculation procedure, judge whether overload or underloading or scarce material state, take the respective handling measure; When not reaching setup parameter value scope, the PLC controller is regulated feeding variable-frequency motor rotating speed automatically according to the deviation of sampling parameter and setup parameter, and the control feeding capacity makes pulverizer stable operation in setting current range.
