TECHNICAL FIELD

[0001] The utility model belongs to the technical field of noise reduction, and particularly relates to a centrifuge sound insulation and noise reduction device for cement concrete pole production. BACKGROUND

[0002] The cement pole centrifuge is a machine that uses the principle of centrifugal force to mix raw materials such as cement, sand, and gravel to form a cement pole with certain strength. It is mainly used to prepare smooth and hard cement poles, which are widely used in the fields of electricity, communication, and transportation as prefabricated components. The working principle of the cement pole centrifuge is relatively simple but efficient. First, the mixed cement material is placed in a mold; then, the mold is placed in the centrifuge, and the motor is started to make the centrifuge body rotate at high speed; during rotation, the centrifugal force uniformly distributes the cement mixture in the mold, allowing it to form a homogeneous and dense cement pole during the solidification process.
