Abstract
The utility model relates to an automatic control system of a vibrating centrifuge. The automatic control system comprises a vibrating-centrifuge working parameter acquisition device, a controller, a frequency converter and a vibrating motor. The vibrating-centrifuge working parameter acquisition device is connected to the vibrating motor through the controller and the frequency converter sequentially. The automatic control system can automatically adjust excitation frequency of the vibrating centrifuge.
Description
Technical field
The utility model relates to a kind of automatic control system of vibrating centrifuge, relates in particular to a kind of control system that can automatically regulate vibrating centrifuge excited frequency.
Background technology
The general employing of vibrating centrifuge determined speed vibration motor exciting; this kind of exciting mode can only produce the vibration of single-frequency; in the time that the outside operating mode such as treating capacity, water content of material changes; the treatment effect of centrifuge does not reach optimum efficiency, and the potential of centrifuge can not be brought into play completely, and in the time shutting down; fixed centrifuge is frequently because downtime is longer; there will be significantly teeter, have a strong impact on the structural strength of centrifuge, with potential safety hazard.
Utility model content
In order to solve the above-mentioned technical problem existing in background technology, the utility model provides a kind of automatic control system that can automatically regulate the vibrating centrifuge of vibrating centrifuge excited frequency.
Technical solution of the present utility model is: the utility model provides a kind of automatic control system of vibrating centrifuge, and its special character is: described automatic control system involving vibrations centrifuge running parameter acquisition device, controller, frequency converter and vibrating motor; Described vibrating centrifuge running parameter acquisition device is successively by controller and frequency converter access vibrating motor.
Above-mentioned vibrating centrifuge running parameter acquisition device comprises moisture content detection device, Weight detecting device and vibration detection device; Described moisture content detection device, Weight detecting device and vibration detection device be access controller respectively; Described controller is connected with vibrating motor by frequency converter.
Above-mentioned Weight detecting device is belted electronic balance; Described moisture content detection device is online moisture detector; Described vibration detection device is one or more vibrating sensors.
Compared with prior art, the utlity model has following advantage:
The automatic control system of vibrating centrifuge provided by the utility model is in the time that centrifuge normally moves, the parameter such as amplitude, frequency for the treatment of capacity by sensor Real-Time Monitoring centrifuge, material moisture, key position, and by these parameter input control devices, by the intelligent algorithm such as neuroid, expert system, obtain best excited frequency value, then drive frequency converter, adjust vibrating motor rotating speed, make centrifuge by this frequency vibration, controller is adjusted excited frequency by certain time interval, makes centrifuge always work in best operating point.In the time shutting down, can control the frequency converter of vibrating motor, vibrating motor is stopped according to specific control curve, can avoid centrifuge in the time shutting down, to occur larger teeter.The utility model can make centrifuge forever be operated in optimal vibration state, and effectively vibration is large, nuisance vibration is little, and no matter how outside operating mode changes, and it all can keep stable vibration and less energy resource consumption.Can also avoid centrifuge in the time shutting down, to occur larger teeter, improve security.
Brief description of the drawings
Fig. 1 is the theory diagram of automatic control system provided by the utility model;
Wherein:
1-moisture content detection device; 2-Weight detecting device; 3-vibration detection device; 4-controller; 5-frequency converter; 6-vibrating motor.
Detailed description of the invention
Referring to Fig. 1, the utility model also provides a kind of automatic control system of vibrating centrifuge, this automatic control system involving vibrations centrifuge running parameter acquisition device, controller 4, frequency converter 5 and vibrating motor 6; Vibrating centrifuge running parameter acquisition device accesses vibrating motor 6 by controller 4 and frequency converter 5 successively.
Vibrating centrifuge running parameter acquisition device comprises moisture content detection device 1, Weight detecting device 2 and vibration detection device 3; Moisture content detection device 1, Weight detecting device 2 and vibration detection device 3 access controller 4 respectively.Arrange at centrifuge feeding mouth and discharging opening that respectively moisture content detection device 1 instrument is to detect material moisture, on the belt conveyor of feeding mouth and discharging opening, arrange that Weight detecting device 2 is with Check processing amount, on centrifuge body, arrange that some vibration detection devices 3 are in order to detected amplitude and frequency.
Weight detecting device 2 is belted electronic balances; Moisture content detection device 1 is online moisture detector; Described vibration detection device 3 is one or more vibrating sensors.
Principle of the present utility model is: in the time that centrifuge moves, the parameter such as amplitude, frequency for the treatment of capacity by sensor Real-Time Monitoring centrifuge, material moisture, key position, and by these parameter input control devices 4, by the intelligent algorithm such as neuroid or expert system, obtain best excited frequency value, then drive frequency converter 5, adjust vibrating motor 6 rotating speeds, make centrifuge by this frequency vibration, controller 4 is adjusted excited frequency by certain time interval, makes centrifuge always work in best operating point.In the time that centrifuge is shut down, according to shifting to an earlier date preset control curve, make vibrating motor 6 control strategy on request realize parking by controlling the frequency converter 5 of vibrating motor 6, avoid centrifuge in the time shutting down, to occur larger teeter.
