Cleaning knowledge about swing screening machine - flat rotary screen
　　Swing screen, also known as swing vibrating screen, is a screening equipment that imitates manual screening actions. This series of equipment has good screening effect on cylindrical, elongated, and irregularly shaped materials without damaging the characteristics and shape of the materials themselves, meeting the requirements of modern people for screening materials: high efficiency and high precision. At present, swing screens are widely used in industries such as chemistry, food, medicine, and fertilizers.　　Do not stack any other debris around the swing screen machine, and the surrounding environment should also be kept clean. The price of the MSG swing screen should not be contaminated with other dust as much as possible to avoid the influence of other debris and prevent inaccurate screening of grains after screening. Before starting up and using the swing screen, it is necessary to check whether there are any debris in the machine compartment. The price of the glass bead swing screen should be cleaned to prevent different debris from mixing together and affecting the accurate screening of grains.　　Swing screens can be cleaned using bouncing balls, which is simple to use and easy to maintain. It is suitable for most granular materials, and ultrasonic cleaning is also a widely used cleaning method. It not only cleans the screen mesh, but also significantly improves production capacity. Suitable for most fine, high-yield, and difficult to screen materials, it improves work efficiency and time.　　Overall, China's swing vibration equipment is constantly improving and upgrading, and the market is showing a thriving trend. In the context of the continuous expansion of the food and drug market, domestic vibrating screen equipment should strengthen innovative technology, integrate market requirements, seize industry trends, and continuously meet the needs of more industries.

Internal factors causing noise in screening machines
　　1. Noise source　　The noise mainly comes from the operation of gears and rolling bearings. The main source of gear noise is gear collision caused by manufacturing errors such as smooth contact. The noise radiated through the shell to the connected structure also promotes the total sound power to be increased at resonance frequency, especially for large diameter gears, whose noise pollution is more serious.　　The noise of rolling bearings is often caused by the impact of the rolling elements in the raceway and the impact and vibration of the retainer inside the bearing. Therefore, it is related to the stiffness and smoothness of the vibrator shaft.　　2. Diffusion　　Resonance diffusion. Due to resonance between the frequency of the noise source and the vibration noise caused by the excitation of the screen, crossbeam, pipe, etc. In addition, resonance occurs when the natural frequency of the component is a multiple of the operating frequency of the sieve. It can be said that there must be resonance phenomenon in the center where strong noise is generated by the mechanical vibrating screen. Related to area. The diffusion noise is proportional to the area. From the characteristics of acoustics, it is difficult for low-frequency sounds to form noise without large-scale vibrations. Therefore, many inherent vibrations of large-scale vibrations are fundamentally in the low-frequency region. From this, it can be seen that there is a relative relationship between the area of the vibrating body and the generation of noise. The sieve, as a vibrating body, generates low-frequency noise due to the large-scale vibration of components such as the sieve plate and frame.　　3. Connect　　Poor connection (looseness) can cause impact, such as the screen frame and screen mesh colliding and the screen body components becoming loose. Due to rigid connections, there is significant noise.
