1、 Purpose and Characteristics
The silo wall vibrator is used to prevent and eliminate various phenomena such as "blockage" and "arching" caused by internal friction, deliquescence, electrification, and component segregation of materials in the silo. It is a good auxiliary equipment for the smooth discharge of materials from the silo mouth, ensuring the normal operation of the entire production process. It is widely used in various industries such as mining, metallurgy, chemical engineering, building materials, and machinery.
The CZ type silo wall vibrator, due to the use of near resonance principle, has the characteristics of small size, long service life, low power consumption, simple structure, and easy installation. Compared with the methods of adding stirring wings, sending pulsating compressed air, etc. to relieve "blockage" and "arching", it has the advantages of low equipment cost and small maintenance.
The CZ type silo vibrator will significantly reduce its ability to break the arch of viscous materials.

working principle:
As shown in Figure (2), the warehouse wall vibrator is composed of vibrating body, resonant spring, electromagnet, base and other components. Vibration
The vibrating mass m1 is composed of components such as the moving body, iron core, and coil, which together with the main vibrating spring form a single body near resonance system. electromagnetism
The coil is powered by alternating current through a half wave rectification circuit and generates electromagnetic force, causing the system to vibrate under forced force. Vibration
The inertia force of the moving mass m1 is transmitted to the warehouse wall through the auxiliary spring, causing slight vibration of the warehouse wall and effectively overcoming the material
The internal friction and cohesion of the material enable it to be smoothly discharged from the hopper mouth.
4、 Maintenance and Debugging
When the machine is working normally, it should meet the following standards:
1. The current does not exceed the rated value;
2. The amplitude of the vibrating body (shell) reaches or exceeds the rated value of 1.7mm;
3. There is no abnormal noise during vibration, generally less than 40-50 decibels.
If the machine malfunctions, it should be stopped for maintenance in a timely manner to avoid damaging other components.

Debugging method:
The vibrator generally operates in a bottom critical near resonance state. The stiffness of the spring directly affects the working state of the vibrator. As the stiffness increases, the amplitude decreases and the current increases; The stiffness decreases, the amplitude becomes unstable, the current increases, and it may also cause collisions between the electromagnets. Specific debugging method: When the stiffness is high, you can slightly loosen the compression bolts at both ends of the spring or increase the weight of the counterweight on the vibrating body; When the stiffness is low, the plate spring can be compressed to tighten the bolt or reduce the weight of the counterweight.
