Household Rice BeaterManufacturer: How to solve the problem of big noise of rice mill fan?

As an important equipment of rice processing enterprises, rice milling machine is also an important noise source. The main causes of noise of rice milling machine are analyzed, including rice milling room, fan (blower and suction fan), drive motor, transmission belt, etc. Today I will introduce the solution of rice milling machine fan noise.

1. When choosing a rice beater, not only the model of the purchased equipment should be determined according to the requirements of the process equipment, but also the selection of the equipment manufacturer and the understanding of the manufacturing level should be paid attention to. Not only the performance of the main body of the rice beater, but also the performance of the fan equipped with the rice beater should be considered. In practice, it is found that even under the same working conditions, the equipment noise level of the same type of different manufacturers are different, the low noise fan has good performance in all aspects, stable and reliable operation, and long service life. In this way, starting from the source of fan noise control, it is particularly worthy of our attention.

2. Select reasonable operation parameters of the fan. Different operation parameters of the fan will produce different noises. Under the conditions of large air volume and high rotating speed, the noise will become larger. For example, the air volume generated by the blower of the rice beater should make the air flow have enough kinetic energy to blow up the rice grains and take the rice bran away through the sieve holes. The wind speed of the spray tank should be higher than the suspension speed of the rice grains, the wind pressure should be able to overcome the network resistance to maintain the necessary air volume to reach the above wind speed. Generally, the air volume required for processing per ton of rice per hour is 100~150 m3/h, the wind speed at the outlet of the air duct is 12~14 m/s, and the air pressure is 100~300 Pa.

3. The inlet and outlet of the fan should be soft-connected, and the base should be equipped with shock-absorbing pads with good strength. When conditions permit, mufflers should be installed at the inlet and outlet of the fan. Coating damping materials on the fan shell can not only reduce the fan radiation Noise can also absorb noise. The thickness of the pipe at the inlet and outlet of the fan has a certain influence on the formation of noise. If the material is thicker, the noise generated by the airflow on the pipe wall will be lower, otherwise it will be higher.

4. Regularly check and maintain the fan, regularly check the bearing oil, and solve the problems in time, especially to remove the dust on the blades of the fan impeller in time, replace the worn bearings and fan impeller in time, ensure the installation of the fan and the connection of various parts are firm, and the fan can run smoothly. At the same time, consider the use environment and working conditions of the fan to ensure that the fan is in good condition. If any abnormal situation is found, stop immediately, do not "work" with illness.
