Description

Technical Field

[0001] This utility model relates to the field of centrifuge noise reduction technology, specifically a centrifuge noise reduction device. Background Technology

[0002] When the rock wool centrifuge is in operation, due to the arrangement and size design of the four centrifugal rollers, as well as the high speed required for production and processing, the centrifugal force cannot fully guarantee the stable centrifugation of the whole machine. During the production process, the whole machine is prone to generating a lot of noise. Therefore, noise reduction devices are needed to reduce the noise of the rock wool centrifuge.

[0003] A Chinese patent with authorization announcement number CN 209324046 U discloses a sound insulation and noise reduction device for a centrifuge. It includes a soundproof wall surrounding the centrifuge, with guide rails on the wall at both the fixed and tensioning ends of the centrifuge. A cover plate driving mechanism is mounted on the guide rails, and a soundproof cover plate is mounted on the cover plate driving mechanism. The cover plate driving mechanism includes a support frame, on which a cylinder, a reducer, a drive wheel, and a driven wheel are mounted, supporting and cooperating with the soundproof cover plate. The reducer is connected to the drive wheel. The soundproof cover plate and the soundproof wall together form a closed soundproof chamber. After the cylinder lifts the soundproof cover plate, the cover plate driving mechanism moves along the guide rails to open the soundproof cover plate. The advantages of this invention are: a reasonable structure, effective reduction of the enormous noise generated during the centrifugation of precast concrete piles, protection of the physical and mental health of operators, and improvement of the working environment in the production workshop.

[0004] Existing noise reduction devices for rock wool centrifuges typically involve installing noise-reducing cotton inside the centrifuge casing to isolate internal noise. However, the vibrations generated during centrifuge operation cause the entire centrifuge to vibrate, easily generating noise and resulting in poor noise reduction, which affects the stability of the rock wool centrifuge. Therefore, a centrifuge noise reduction device is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems existing in the existing technology, this utility model proposes a centrifuge noise reduction device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a centrifuge noise reduction device, including a base with a ramp. A groove is formed on the base, and a shock-absorbing plate is assembled within the groove. Two sets of sliding grooves are formed on the shock-absorbing plate. A lead screw is rotatably mounted on the inner wall of each sliding groove. The threads on the lead screw are symmetrically opposite in direction. A damping wheel is mounted at one end of the lead screw. Two sliders are symmetrically assembled within each sliding groove. Clamping blocks are mounted on the sliders. The clamping blocks have an L-shaped structure. Two sets of rod seats are fixedly mounted on the side wall of the shock-absorbing plate. Threaded holes are installed on the rod seats, and equipment is assembled within the threaded holes. The system includes a screw with a knob mounted on it. A rubber pad is installed on the inner side wall of the groove, located between the groove and the damping plate. Rotation of the screw causes two sliders to move synchronously relative to each other, which in turn causes two clamping blocks to move synchronously relative to each other. These four clamping blocks clamp and fix the four corners of the rock wool centrifuge base, thus achieving overall fixation and stable placement of the rock wool centrifuge. This prevents vibration of the centrifuge on the ground, reduces noise generated by overall vibration, and improves the noise reduction effect.

[0007] Preferably, the base has an assembly groove inside, and a connecting groove is formed between the assembly groove and the plate groove. A buffer plate is assembled in the assembly groove, and a connecting plate is installed on the buffer plate. The connecting plate is assembled in the connecting groove. Multiple dampers are rotatably mounted on the bottom and side walls of the buffer plate via ball seats. The other end of the damper is rotatably connected to the inner wall of the assembly groove via a ball seat. Multiple springs are installed on the bottom and side walls of the buffer plate. The other end of the springs is fixedly connected to the inner wall of the assembly groove. The springs are sleeved around the dampers. A rock wool centrifuge is placed on the shock-absorbing plate. The rock wool centrifuge is equipped with a base, on which four sets of pulleys are rotatably mounted. Shock-absorbing cotton is installed on the inner wall of the rock wool centrifuge shell. Four clamping blocks clamp and fix the four corners of the rock wool centrifuge base. When the rock wool centrifuge is in operation, vibration will be generated inside the rock wool centrifuge, thereby causing the entire rock wool centrifuge to vibrate. This structure absorbs the impact force and reduces the vibration through the elastic deformation of the spring and the resistance of the damper, avoiding damage to the rock wool centrifuge due to prolonged impact, and improving the protection of the rock wool centrifuge.

[0008] The advantages of this utility model are:

[0009] 1. This utility model utilizes a lead screw rotation, which drives two sliders on the lead screw to move synchronously relative to each other. The two sliders then drive two clamping blocks to move synchronously relative to each other. The four clamping blocks clamp and fix the four corners of the rock wool centrifuge base, thus achieving overall fixation and clamping of the rock wool centrifuge. This ensures stable placement of the rock wool centrifuge, prevents vibration of the rock wool centrifuge on the ground, reduces noise generated by overall vibration of the rock wool centrifuge, and improves the noise reduction effect of the rock wool centrifuge.

[0010] 2. This utility model uses four clamping blocks to clamp and fix the four corners of the rock wool centrifuge base. When the rock wool centrifuge is in operation, vibration will be generated inside the rock wool centrifuge, thereby causing the entire rock wool centrifuge to vibrate. This structure absorbs the impact force and reduces the vibration through the elastic deformation of the spring and the resistance of the damper, avoiding damage to the rock wool centrifuge due to long-term impact force, and thus improving the protection of the rock wool centrifuge.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3 As shown, a centrifuge noise reduction device includes a base 1 with an inclined surface and a groove 2. A damping plate 3 is installed in the groove 2, and two sets of sliding grooves 4 are provided on the damping plate 3. A lead screw 5 is rotatably mounted on the inner wall of the sliding groove 4. The threads on the lead screw 5 are symmetrically opposite in direction. A damping wheel 6 is installed at one end of the lead screw 5. Two sliders 7 are symmetrically assembled in the sliding groove 4, and clamping blocks 8 are installed on the sliders 7. The clamping blocks 8 have an L-shaped structure. Two sets of rods are fixedly installed on the side wall of the damping plate 3. The seat 9 has a threaded hole, and a screw 10 is fitted into the threaded hole. A knob 11 is installed on the screw 10. A rubber pad 12 is installed on the inner side wall of the plate groove 2, and the rubber pad 12 is located between the plate groove 2 and the shock-absorbing plate 3. During operation, existing noise reduction devices for rock wool centrifuge 18 typically install noise-absorbing cotton inside the outer shell of the rock wool centrifuge 18 to isolate the noise inside the centrifuge. However, the vibration generated inside the centrifuge during operation can cause the rock wool centrifuge to vibrate. The overall vibration of the rock wool centrifuge 18 easily generates noise, resulting in poor noise reduction and affecting its stability. To address this, the rock wool centrifuge 18 is pushed onto the base 1 along its slope. Then, two damping wheels 6 are rotated, causing the lead screw 5 to rotate. The lead screw 5 drives two sliders 7 to move synchronously relative to each other, which in turn drives two clamping blocks 8 to move synchronously relative to each other. The four clamping blocks 8 clamp and fix the four corners of the base 19 of the rock wool centrifuge 18. Then, the knob 11 is rotated, causing the screw 10 to rotate and move horizontally, tightening the screw 10 so that it abuts against the damping wheel 6, locking the lead screw 5 and securing the entire rock wool centrifuge 18. This ensures stable placement of the rock wool centrifuge 18, preventing vibration on the ground and reducing noise generated by overall vibration, thus improving the noise reduction effect.

[0020] Please see Figure 4-5As shown, the base 1 has an assembly groove 13 inside, and a connecting groove 14 is formed between the assembly groove 13 and the plate groove 2. A buffer plate 15 is assembled in the assembly groove 13, and a connecting plate 16 is installed on the buffer plate 15. The connecting plate 16 is assembled in the connecting groove 14. Multiple dampers are rotatably mounted on the bottom and side walls of the buffer plate 15 through ball seats. The other end of the damper is rotatably connected to the inner wall of the assembly groove 13 through the ball seats. Multiple springs 17 are installed on the bottom and side walls of the buffer plate 15, and the other end of the springs 17 is fixedly connected to the inner wall of the assembly groove 13. Spring 17 is sleeved around the damper. Rock wool centrifuge 18 is placed on the damping plate 3. A base 19 is installed on the rock wool centrifuge 18. Four sets of pulleys 20 are rotatably installed on the base 19. Damping cotton is installed on the inner wall of the rock wool centrifuge 18. During operation, the existing noise reduction device is difficult to protect the rock wool centrifuge 18 during the noise reduction process. The rock wool centrifuge 18 is easily damaged by long-term vibration, resulting in poor protection of the rock wool centrifuge 18. The four clamps 8 are used to respectively protect the rock wool centrifuge 18. The four corners of the base 19 of the rock wool centrifuge 18 are clamped and fixed, thus achieving the overall fixation and clamping of the rock wool centrifuge 18. When the rock wool centrifuge 18 is operating, vibration will be generated inside the rock wool centrifuge 18, thereby causing the entire rock wool centrifuge 18 to vibrate. The rock wool centrifuge 18 drives the vibration damping plate 3 to vibrate, the vibration damping plate 3 drives the vibration connecting plate 16 to vibrate, and the vibration connecting plate 16 drives the vibration buffer plate 15. The vibration of the buffer plate 15 causes the spring 17 to undergo elastic deformation. The spring 17 stores energy through deformation, and its action absorbs the impact. The damper works simultaneously to reduce impact and vibration. The damper reduces impact and vibration through frictional resistance. During the damping process, when the spring 17 returns to its original position, the damper prevents the spring 17 from rebounding and dissipates the energy stored in the spring 17, thus bringing the spring 17 to a standstill. This structure absorbs impact and reduces vibration through the elastic deformation of the spring 17 and the resistance of the damper, preventing the rock wool centrifuge 18 from being damaged by prolonged impact and improving the protection of the rock wool centrifuge 18.

[0021] Working principle: Existing noise reduction devices typically install noise-reducing cotton inside the outer shell of the rock wool centrifuge 18 to isolate internal noise. However, the vibration generated inside the centrifuge during operation causes the entire rock wool centrifuge 18 to vibrate, easily generating noise and resulting in poor noise reduction effect, affecting the stability of the rock wool centrifuge 18. The new method involves pushing the rock wool centrifuge 18 onto the base 1 along the slope, then rotating two damping wheels 6 to drive the lead screw 5. The lead screw 5 drives two sliders 7 on it to move synchronously relative to each other, and the two sliders 7 drive two clamps... Blocks 8 move synchronously relative to each other, and the four clamping blocks 8 clamp and fix the four end corners of the base 19 of the rock wool centrifuge 18 respectively. Then, the knob 11 is turned, which drives the screw 10 to rotate and move horizontally at the same time, tightening the screw 10 so that the screw 10 abuts against the damping wheel 6, thereby locking the lead screw 5 and fixing the rock wool centrifuge 18 as a whole. This achieves stable placement of the rock wool centrifuge 18, avoids vibration of the rock wool centrifuge 18 on the ground, reduces the noise generated by the overall vibration of the rock wool centrifuge 18, and helps to improve the noise reduction effect of the rock wool centrifuge 18. The existing noise reduction device for the rock wool centrifuge 18 During noise reduction, it is difficult to protect the rock wool centrifuge 18, as it is prone to damage from prolonged vibration. This results in poor protection for the rock wool centrifuge 18. Four clamping blocks 8 are used to clamp and fix the four corners of the base 19 of the rock wool centrifuge 18, achieving overall fixation of the rock wool centrifuge 18. When the rock wool centrifuge 18 is operating, internal vibrations occur, causing the entire centrifuge to vibrate. The rock wool centrifuge 18 drives the vibration damping plate 3, which in turn drives the vibration of the connecting plate 16, which in turn drives the vibration of the buffer plate 15. The movement causes the spring 17 to undergo elastic deformation. The spring 17 stores energy through deformation, and its function is to absorb impact force and reduce vibration. At the same time, the damper operates, and the damper reduces impact force and vibration through frictional resistance. During the damping process, when the spring 17 returns to its original position, the damper will prevent the spring 17 from rebounding and dissipate the energy stored in the spring 17, thus achieving the stationary state of the spring 17. This structure absorbs impact force and reduces vibration through the elastic deformation of the spring 17 and the resistance of the damper, preventing the rock wool centrifuge 18 from being damaged by impact force for a long time, which helps to improve the protection of the rock wool centrifuge 18.
