At present, most of the biomass crushers in our country have a hammer crushing structure. Compared with the hammer biomass crusher, the biomass crusher has obvious pioneering advantages.
The biomass crusher uses various cutting and crushing mechanisms between two relatively rotating tools to destroy materials. The "dual motor dual planetary reducer" has strong driving force and high operating safety. This equipment has a low speed ratio and high torque. It has the characteristics of large shear stress, significant crushing effect, low noise and good safety.
The raw materials are stacked one after another along the direction of the chain conveyor of the biomass crusher to obtain the material. After the raw materials enter the biomass crusher, they are sent into the biomass crusher for crushing using the upper adhesive. When the biomass is crushed When the machine is running, the intelligent monitoring system temporarily stops the operation of the chain conveyor and temporarily stores some raw materials on the conveyor belt to ensure that the raw materials are continuously supplied in sufficient quantity, thereby preventing the biomass raw materials from being stored in the crushing chamber. Accumulation. The broken biomass raw materials are collected and collected on this discharge conveyor belt, and the output biomass is processed in the next step.
Various maintenance tests should be done before starting the biomass crusher, so that the biomass crusher can be put into use with confidence. However, ordinary crushers have signal detection such as load, short circuit failure, phase failure protection, etc. The purpose is to avoid overcurrent. Water leakage, short circuit failure and other reasons cause burnout, which affects the normal operation of other machines. Here we also introduce the necessity of vibration signal detection.
When the leaves of the biomass crusher are entangled with debris in the water, the impeller rotates unevenly, which will cause obvious vibration. The purpose of connecting the piezoresistive vibration sensor is to check the vibration situation in a timely manner, so as to know whether the sensor is operating normally. It is composed of a torsion spring, a quality block piezoelectric sheet and a base. The sensor base is rigidly fixed around the bearing between the motor and the sensor to experience mechanical vibration.
When the sensor is subjected to vibration, since the stiffness of the spring is particularly large and the mass of the mass block is relatively small, it can be felt that the inertial force of the mass is not large. Therefore, the mass block will vibrate in the same direction as the base of the sensor and experience the same acceleration direction. In that case, the mass block has an alternating force proportional to the acceleration acting on the piezoelectric element. Since the piezoelectric element has a piezoelectric effect, alternating charges are formed on its two surfaces.
In addition, in order to detect the information content of the biomass crusher in real time, a temperature sensor, a vibration sensor, an oil and water probe for water leakage detection, a float switch, etc. were selected, and the supervision and maintenance of the motor was realized through the control circuit. I hope that there will be more in the future Customers can realize that during the operation process, the detection signal under the working status is the information carrier that reflects the normal or abnormal operating status, and appropriate inspection methods are the main conditions for discovering fault information.
