Description

Technical Field

[0001] This application provides an automatic noise reduction system for a pipe mold centrifuge chamber, relating to the field of concrete pipe pile and pole manufacturing. Background Technology

[0002] During the centrifugation process in the manufacturing of pipe piles, the centrifuge chamber generates noise as the centrifuge drives the pipe mold to rotate at high speed. This noise can spread to the surrounding area of ​​the centrifuge chamber, affecting the surrounding production environment and the hearing of the workers. In such cases, a device or system is often needed to effectively block the noise generated by the centrifuge, isolate the noise within the centrifuge chamber and prevent it from spreading outward, thereby improving the working environment around the centrifuge chamber and protecting the hearing of the workers in the surrounding area.

[0003] In existing pipe pile production layouts, centrifuge chambers are often arranged in groups of 5 to 7 or more, with 4 to 6 centrifuges operating simultaneously according to the production process. These centrifuge chambers are typically divided by concrete or steel retaining walls, leaving the top open. To achieve noise reduction, current technology usually involves adding soundproof covers to seal the openings above the centrifuge chambers. However, opening these covers requires numerous additional drive mechanisms and can interfere with adjacent centrifuge chambers, increasing the floor space occupied by the centrifuge chambers and impacting work efficiency.

[0039] Example

[0040] This application provides an embodiment of an automatic noise reduction system for a tube-shaped centrifuge chamber. See also... Figure 1It includes an outer ring soundproof wall 100 that is square in shape. Inside the outer ring soundproof wall 100, there are N centrifuge chambers arranged adjacent to each other along a first direction (X direction in the figure), namely the first centrifuge chamber 101, the second centrifuge chamber 102, ..., the Nth centrifuge chamber 103, where N ≥ 2. An internal soundproof wall is set between the centrifuge chambers. The N centrifuge chambers are arranged in sequence, with each pair of centrifuge chambers forming a pair. The odd-numbered centrifuge chambers in a pair are classified as first-type centrifuge chambers, and the even-numbered centrifuge chambers are classified as second-type centrifuge chambers.

[0041] Taking any pair of centrifuge chambers as an example, see Figure 2 The centrifuge chamber 110 has a low-position sliding soundproof cover 111 above it, and the centrifuge chamber 120 has a high-position sliding soundproof cover 121 above it. In use, when the centrifuge chamber 110 needs to be opened, the low-position sliding soundproof cover 111 slides between the centrifuge chamber 120 and the high-position sliding soundproof cover 121; when the centrifuge chamber 120 needs to be opened, the high-position sliding soundproof cover 121 slides above the low-position sliding soundproof cover 111 of the centrifuge chamber 120, allowing the low-position sliding soundproof cover 111 and the high-position sliding soundproof cover 121 of the centrifuge chamber to slide open alternately.

[0042] This embodiment utilizes the height difference of the soundproof cover of adjacent centrifuge chambers to slide the soundproof cover of the centrifuge chamber to the adjacent centrifuge chamber to open the centrifuge chamber, and to hoist and place the pipe pile mold. The centrifuge chamber does not need to reserve extra space for opening the soundproof cover, thereby reducing the footprint of the centrifuge chamber. More pipe mold centrifuge chambers with automatic noise reduction can be arranged in the same size factory space.

[0043] In a specific implementation, the low-position sliding soundproof cover 111 of the first type of centrifuge chamber is located in the second direction ( Figure 1The front and rear ends of the Y-direction shown are equipped with low-position roller groups. The low-position roller groups include at least two low-position rollers 112 distributed on the left and right sides. The top of the outer ring soundproof wall is correspondingly provided with a low-position track 130 along the first direction. The low-position rollers 112 run on the low-position track 130. The low-position sliding soundproof chamber cover 111 slides to the top of the second type of centrifuge chamber to open the first type of centrifuge chamber. The high-position sliding soundproof cover 121 of the second type centrifuge chamber is provided with high and low roller groups at both the front and rear ends in the second direction. The high and low roller groups include a high roller 122 located on the side closer to the first type centrifuge chamber and a low roller 123 located on the side away from the first type centrifuge chamber. The low roller 123 also runs on the low track 130. The upper surface of the low-position sliding soundproof cover 111 is correspondingly provided with a high track 113 along the first direction. The high roller 122 runs on the high track 113, so that the high-position sliding soundproof cover 121 is partially mounted above the low-position sliding soundproof cover 111. The high-position sliding soundproof cover 121 can slide to the top of the low-position sliding soundproof cover 111, thereby opening the second type centrifuge chamber.

[0044] See Figure 3 To ensure no structural interference when the low-sliding soundproof cover slides between the second-type centrifuge chamber and the high-sliding soundproof cover, a layered space is provided between the high-sliding soundproof cover and the second-type centrifuge chamber to allow the low-sliding soundproof cover to move. Simultaneously, to achieve sound insulation, soundproof curtains 124 are installed on all four sides of the high-sliding soundproof cover. These curtains, made of sound-insulating material, hang down from all four sides of the high-sliding soundproof cover and contact the soundproof wall of the second-type centrifuge chamber, thus sealing the layered space. A load is provided on the soundproof curtains so that they can maintain contact with the soundproof wall under their own weight. When it is necessary to open the first-type centrifuge chamber, the low-sliding soundproof cover slides into the layered space, lifting the soundproof curtains and moving them between the high-sliding soundproof cover and the second-type centrifuge chamber, thus opening the first-type centrifuge chamber.

[0045] It is understandable that in the aforementioned technical solutions, the first type of centrifuge chamber uses a low-position sliding soundproof cover, while the second type of centrifuge chamber uses a high-position sliding soundproof cover. They can also be configured in reverse, for example, the first type of centrifuge chamber uses a high-position sliding soundproof cover while the second type of centrifuge chamber uses a low-position sliding soundproof cover. The structural principle is the same, as long as they can be opened in an alternating sliding manner.

[0046] The staggered sliding soundproof cover provided in this embodiment adapts to each pair of adjacent centrifuge chambers, so the total number of centrifuge chambers N is usually an even number. When N is an odd number, except for the last centrifuge chamber, the preceding N-1 centrifuge chambers can be distributed alternately according to the first type of centrifuge chamber and the second type of centrifuge chamber. The last centrifuge chamber adopts a low-position sliding soundproof cover. When it needs to be opened, the cover of the N-1 centrifuge chamber is opened first (slid open towards the N-2 centrifuge chamber) to reserve space for the opening of the cover of the last centrifuge chamber. The cover of the last centrifuge chamber can then be slid above the N-1 centrifuge chamber.

[0047] Specifically, the soundproof canopy adopts a long frame structure, see [link / reference]. Figure 4 , Figure 5 , Figure 6 The main structure of the soundproof chamber cover includes a frame 1411, which is made of rectangular tubing. The outer side (upper surface) of the frame is sealed with a thin plate 1412, the inside of the frame is filled with sound-insulating material 1416, and the inner side (lower surface) of the frame is sealed with a porous sound-absorbing plate 1413. This structure can absorb noise generated inside the centrifuge chamber and block its outward propagation. A rack 1414 is installed at each end of the soundproof chamber cover, and angle steel wheels 1415 are distributed near the four corners of the cover. The sliding of the cover is driven by a motor, which is fixed to the soundproof wall of the centrifuge chamber. The motor's output shaft is connected to the rack 1414 via a gear set, driving the cover to slide. Limit blocks are set at both ends of the rack 1414; the motor automatically stops when the cover slides to the correct position. Furthermore, proximity switch sensors can be installed at the target sliding position (closed position, open position) of the soundproof cover to identify whether the soundproof cover has slid into place, and can be linked with the motor to facilitate the automatic opening or closing of the soundproof cover.

[0048] In a further embodiment, the outer ring soundproof wall has openings corresponding to each centrifuge chamber, with door frames 1531 and soundproof doors. Technicians can enter the centrifuge chamber by opening the soundproof doors. The door frames 1531 are made of channel steel, and the soundproof door body 1532 is a frame structure. (See [reference]). Figure 7 , Figure 8 and Figure 9 The door 1532 is sealed on both the inner and outer sides with thin plates 1535, and the interior of the door is filled with sound-insulating material 1537. The door is connected to the door frame 1531 by hinges 1533, and a locking rod 1504 is installed on the door to ensure a full fit between the door and the door frame and to guarantee airtightness. This structure can absorb noise generated inside the centrifuge chamber and block its outward transmission. Two observation windows 1536 are installed on the door to allow operators to observe the centrifuge's operation at any time. A safety limit switch 1534 is installed on the door to detect whether the door is closed and to interlock with the centrifuge, drive motor, and other equipment to ensure safe operation.

[0049] The use of a motor and proximity switch sensor in this embodiment is based on cost considerations. This embodiment is not limited to using a servo motor in conjunction with the above; other actuators with variable frequency motors or other controllable strokes can also be used to achieve the above technical objectives.

[0050] The technical solution of this embodiment uses a soundproof cover and soundproof door to effectively seal the centrifuge chamber. The noise generated when the centrifuge drives the tube mold to perform centrifugation is blocked inside the centrifuge chamber and prevents the noise from spreading outward. This greatly improves the noise environment around the centrifuge chamber, protects the hearing of the centrifuge operators from damage, and meets the production cycle requirements.

[0051] It is understood that in the automatic noise reduction system for tube-shaped centrifuge chambers provided in this application embodiment, some equipment operations require manual operation by technicians, while others can be automated. For the automated parts, it is often necessary to rely on relevant control programs, such as connecting and controlling corresponding motors and sensors through a programmable logic controller (PLC) to achieve the corresponding functions. After reading and understanding the automatic noise reduction system for tube-shaped centrifuge chambers provided in this application embodiment, those skilled in the art can adapt and adjust the automated parts. The automated parts can be easily controlled by various programs to control related equipment, motors and other drivers, proximity switches and sensors, safety limit switches and other sensors. For example, a host computer program can be developed using software such as WINCC and communicated with the PLC. The PLC can then control various electrical control devices to achieve the corresponding functions. There are no technical obstacles for those skilled in the art, and no creative effort is required.

[0052] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application in any form or substance. It should be noted that those skilled in the art can make several improvements and additions without departing from this application, and these improvements and additions should also be considered within the scope of protection of this application. Any modifications, alterations, and equivalent variations made by those skilled in the art based on the disclosed technical content without departing from the content and scope of this application are equivalent embodiments of this application. Furthermore, any equivalent changes, alterations, and variations made to the above embodiments based on the essential technology of this application still fall within the scope of the technical solution of this application.
