AI Technical Summary
During the manufacturing process of concrete pipe piles, the noise generated by the centrifuge during operation is transmitted outward through the open layout structure, affecting the surrounding environment and the hearing of the operators. Moreover, existing technologies are insufficient to effectively block the transmission of noise to meet the production cycle requirements.
Design a sound insulation and noise reduction device for a tube-shaped centrifuge chamber. The device uses an alternating upper and lower sound insulation cover, and a transmission mechanism to move and cover the cover. The opening and closing of the upper and lower sound insulation covers are controlled by the first and second transmission mechanisms respectively, forming an automatic noise reduction system.
It effectively reduces the impact of centrifuge noise on the external environment, protects the hearing of nearby employees from damage, and meets production cycle requirements.

A sound insulation and noise reduction device for a tubular centrifuge chamber, used for multiple centrifuge chambers arranged side-by-side in a continuous manner, characterized in that, The system includes an upper soundproof cover and a lower soundproof cover, which are alternately arranged on the upper opening of the centrifuge chamber. A first transmission mechanism is provided between the upper soundproof cover and at least one adjacent lower soundproof cover. Through the first transmission mechanism, the upper soundproof cover can be moved toward at least one adjacent lower soundproof cover to open by covering the adjacent lower soundproof cover. A second transmission mechanism is provided between the lower soundproof cover and at least one adjacent centrifuge chamber. Through the second transmission mechanism, the lower soundproof cover can be moved toward at least one adjacent upper soundproof cover to open by covering the adjacent upper soundproof cover.
2. The soundproofing and noise reduction device for a tube mold centrifugal chamber according to claim 1, characterized in that, The first transmission mechanism includes a first track, a first roller, a first rack, and a first gear. The first track is disposed on the lower soundproof cover, and the first rack and the first roller are disposed on the upper soundproof cover. The first rack meshes with and is connected to the first gear. The first gear is driven to rotate by a first motor, which in turn drives the first rack to move, causing the first roller to move along the first track.
3. The soundproofing and noise reduction device for a tube mold centrifugal chamber according to claim 2, characterized in that, The first motor is equipped with a first position sensor for detecting the opening and closing of the upper soundproof cabin cover.

The second rack meshes with and is connected to the second gear. The second gear is driven to rotate by a second motor, which in turn drives the second rack to move, causing the second roller to move along the second track.
5. The soundproofing and noise reduction device for a tube mold centrifugal chamber according to claim 4, characterized in that, The output shaft of the second motor is connected to the driving sprocket, the driving sprocket is connected to the driven sprocket via a chain, and the second gear is connected to the driven sprocket via a transmission shaft.
6. The soundproofing and noise reduction device for a tube mold centrifugal chamber according to claim 4, characterized in that, The second motor is mounted on the inner wall of the centrifuge chamber.
