Abstract
The utility model discloses a milling sound detection system structure. The system comprises a sensor which corresponds to a mill, and is characterized in that the sensor is connected with an amplifier and transmits a sound signal which is sensed by the sensor and is generated by friction between a steel ball and the mill to the amplifier for conversion; the converted signal is transmitted to a frequency filter; the frequency of the signal is calculated through the frequency filter; the frequency filter is connected with a frequency selection circuit; the frequency selection circuit is connected with a compensated amplifier; the signal is converted into a digital signal through the compensated amplifier and is displayed by a liquid crystal digital display screen; the compensated amplifier is respectively connected with a high-level alarm module and a low-level alarm module. The system is high in reliability, the measurement accuracy and the sensitivity are high, the transmission distance is long, the circuit garbling is small, the average output per machine hour of the mill can be improved, the power consumption is reduced, the labor intensity of workers is reduced, and the service life of a grinding body and a lining plate is prolonged.
Description
Technical field
The utility model relates to a kind of detection system, is specifically related to a kind of mill sound detect system architecture.
Background technology
Ball mill is the key equipment of various material grindings, and the centrifugal force that grinding machine produces by flat sleeping revolution is mentioned steel ball in grinding machine to certain height, to be parabola and to fall and realize the bang of material and grinding.Because grinding machine inside is the grinding space of relative closure, the metering of mill feeding end and discharge end can not accurately be grasped because accumulated error can cause grinding material in grinding machine, therefore, grinding machine can not operate in best grinding state, and the grinding efficiency of grinding machine and service life all can be subject to larger weakening.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mill sound detect system architecture, this system reliability is high, guaranteed that the accuracy of measuring is highly sensitive, transmitting range is far away, line-hit is little, can improve the average unit-hour output of grinding machine, reduces power consumption, alleviate labor strength, extend the life-span of abrasive body and liner plate.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of mill sound detect system architecture, this system comprises a sensor corresponding with grinding machine, it is characterized in that: described sensor is connected with an amplifier, and the transmission of sound signals that friction between steel ball that sensor senses and grinding machine is sent is changed to amplifier, signal after conversion is transferred to frequency filter, by frequency filter, calculate the frequency of signal, described frequency filter is connected with frequency selection circuit, described frequency selection circuit is also connected with compensated amplifier, by compensated amplifier, convert signal to data signal, by liquid crystal digital display, demonstrated.
Described compensated amplifier is also connected with low alarm module with full level alarm module respectively.
The beneficial effects of the utility model are: this system reliability is high, have guaranteed that the accuracy of measuring is highly sensitive, and transmitting range is far away, line-hit is little, can improve the average unit-hour output of grinding machine, reduces power consumption, alleviate labor strength, extend the life-span of abrasive body and liner plate.
