Abstract
The utility model relates to an optimum revolving speed automatic searching and control device for an intermittent ball mill. The optimum revolving speed automatic searching and control device is characterized by comprising sound sensors, a signal conditioning device, a microprocessor, a signal processing device, a transducer and a motor, which are connected in sequence, wherein the motor is connected with a rotary drum of the ball mill, and the sound sensors are arranged at the periphery of the rotary drum of the ball mill. Through searching and control, the intermittent ball mill is enabled to operate at optimum revolving speed anytime, the grinding efficiency of the ball mill is improved, the grinding time is reduced, the productivity of a unit set is improved, and the effect of saving electricity is remarkable.
Description
Technical field
The utility model relates to a kind of intermittent ball mill optimum speed Automatic-searching and control device, is particularly suitable for being applied to architectural pottery raw material ball grinding machine.
Background technology
In each building ceramic enterprises, the energy consumption of raw material ball grinding machine accounts for more than 40% of whole enterprise energy consumption, and ball grinder saving energy has very large realistic meaning.Determine that ball mill grinding efficient has following several respects factor: 1: drum's speed of rotation; 2: the density of abrasive body, size, grating and shape; 3: the ratio of material, ball, water; 4: the diameter of ball mill and useful load.Wherein drum's speed of rotation accounts for space of top prominence, and under the identical prerequisite of other several respects, its milling time of the ball mill that moves under optimum speed more generally can shorten 15--25%.At present, the rotating speed of domestic each used intermittent ball mill of ceramics factory or constant, simply divide several sections on frequency converter, manually to set, owing to can't predict the optimum speed size, even if be set in by chance optimum speed, but along with the carrying out of grinding and the again change of mill condition and its optimum speed also changes during the dress mill thereupon, all be difficult to be operated under the optimum speed at any time.
Notification number is that the Chinese patent of CN201316656Y discloses a kind of energy-saving device of ball grinder, it is by the transformation voltage-stablizer, microprocessor, change-over switch, frequency converter, weight sensor forms, weight sensor is arranged between the ground and support of ball mill, weight sensor is passed to frequency converter to ball mill by comminuting matter weight change signal, microprocessor sends treated signal to frequency converter, frequency converter is implemented variable-frequency variable-voltage according to the signal that receives to the electric current that power supply provides, electric current behind the variable-frequency variable-voltage sends motor to, make motor in balling drum, keep during by the weight change of comminuting matter rotating speed constant, thereby guarantee best crushing effect, realize energy-conservation.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of at any time Automatic-searching to the intermittent ball mill optimum speed and control the device that it moves always under this state.
The concrete technical scheme that the utility model adopts is:
A kind of intermittent ball mill optimum speed Automatic-searching and control device, it is characterized in that, comprise the sound transducer, signal regulating device, microprocessor, signal processing apparatus, frequency converter, the motor that connect successively, motor is connected with balling drum, and sound transducer is arranged on around the balling drum.
Sound transducer can be arranged on the cylinder upper and lower, left and right, and it does not contact with cylinder, is used for picking up the mill tone signal, as the foundation of judging the ball mill running status; Signal processing apparatus adopts large scale integrated circuit; Adopt the Frequency Converter Control drum's speed of rotation, the three organically combines and jointly finishes control task.
Principle of the present utility model is to control according to the mill change of tune that the intermittent ball mill rotation speed change is brought.When ball mill is operated in optimum speed, mill sound tool respective tones spectrum signature.According to this principle method with frequency scanning, find at any time the optimum speed of ball mill and control it and under this state, move always.
The beneficial effect that the utility model has is: the utility model is operated under the optimum speed at any time by seeking and control intermittent ball mill, so that ball mill grinding efficient improves, milling time shortens, and improve machine separate unit production capacity, and power savings is considerable.
Description of drawings
Fig. 1 is block diagram of the present utility model.
Among the figure, 1-balling drum, 2-sound transducer, 3-signal regulating device, 4-microprocessor, 5-signal processing apparatus, 6-frequency converter, 7-motor.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, sound transducer 2 picks up balling drum 1 mill tone signal, by signal regulating device 3 conditionings, give again afterwards signal processing apparatus 4, mill sound respective tones spectrum signature when sending into microprocessor 5 with optimum speed is compared, adjust frequency converter 6 control motors 7 rotating speeds, make it to reach optimum speed.The utility model is arranged in the frequency converter control cabinet.
