At present, most domestic biomass crushers are of hammer-type structure. Compared with hammer-type biomass crushers, biomass crushers have significant pioneering advantages.
The biomass grinder uses various cutting and breaking principles between two relatively rotating tools to destroy the material. The "dual motor dual planetary reducer" is powerful and has high operational reliability. The equipment has the characteristics of low rotation speed and large torque. Characteristics include large shear stress, obvious crushing effect, low noise, and good reliability.
The raw materials are stacked in sequence along the feeding direction of the chain conveyor of the biomass crusher to produce materials. After the raw materials enter the biomass crusher, they are sent to the biomass crusher for crushing using the upper binder. When the biomass crusher During operation, the intelligent control system temporarily stops the operation of the chain conveyor and temporarily stores some raw materials on the conveyor belt to ensure a continuous supply of sufficient raw materials, thus preventing the accumulation of biomass raw materials in the crushing chamber. A discharge conveyor collects and collects the crushed biomass raw materials and processes the output biomass fuel in the next process.
Various protection inspections should be carried out before starting the biomass crusher, so that the biomass crusher can be put into use with confidence. Generally, the crusher has signal detection such as load, short circuit, phase failure protection, etc. The purpose is to avoid overcurrent. Water leakage, short circuit and other reasons may cause burnout and affect the normal operation of other equipment. Here we will introduce to you the importance of vibration signal detection.
When the blades of the biomass crusher are entangled with impurities in the water, causing the impeller to rotate unbalanced, strong vibrations will occur. The purpose of connecting the piezoresistive vibration sensor is to detect the vibration status in a timely manner to understand whether it is operating normally. The inductor is composed of a spring, a mass piezoelectric piece and a base. The inductor base is rigidly fixed around the bearing between the motor and the motor to feel the mechanical vibration.
When the sensor is subjected to vibration, because the stiffness of the spring is very large and the mass of the mass block is relatively small, it can be considered that the inertia of the mass is not large. Therefore, the mass block feels the same vibration as the base of the sensor and is subject to acceleration. In this way, the mass block has an alternating force proportional to the acceleration acting on the piezoelectric element. Because the piezoelectric element has a piezoelectric effect, alternating charges are formed on its two surfaces.
In addition, in order to check the information content of the biomass crusher in real time, temperature sensors, vibration sensors, oil and water probes for water leakage detection and float switches were selected, and the control circuit was used to complete the supervision and protection of the motor. We also hope that many consumers can Realize that during operation, the inspection signal of the working condition is an information carrier that reflects the normal or abnormal operating status, and appropriate inspection methods are the main conditions for discovering fault information.
