Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuges, and in particular relates to a disc-type centrifuge with vibration reduction and noise reduction. Background Art

[0002] In current industrial production, disc separators are key equipment widely used in fields such as mineral oil purification, dairy processing, vegetable oil refining, and pharmaceutical manufacturing. However, significant vibration and noise generated during operation not only affect the stable operation and efficiency of the equipment, but also have adverse effects on the working environment and operators.

[0003] Traditionally, to alleviate this problem, manufacturers have typically installed vibration-damping brackets between the separator body and the base. While this approach mitigates vibration to some extent, its effectiveness is limited and doesn't fundamentally address the problem. More critically, due to the constant vibrations experienced by the separator during operation, traditional metal pipe connections are unable to withstand this dynamic stress and are easily damaged, leading to leaks or breakage at the joints, increasing maintenance costs and downtime. Consequently, many disc separators are forced to use hose connections, which in turn limits their application when handling high-pressure, high-temperature, or corrosive materials.

[0004] A deeper analysis of the root cause revealed that the primary source of vibration and noise was the drive motor. Because the motor is mounted directly on the separator, and the connection between the two is often rigid, the motor's vibration is directly transmitted to the entire separator system, exacerbating the vibration and noise. Furthermore, while the separator's heavy casing provides some mechanical protection, it's limited in terms of sound insulation and noise reduction, failing to effectively isolate the noise caused by the motor and vibration.

[0005] In summary, to improve the operational stability and efficiency of disc separators, while also improving the working environment and reducing noise pollution, it was necessary to fundamentally improve the connection between the drive motor and the separator body and design an innovative vibration-damping and noise-reducing structure to effectively control vibration and noise. Such an improvement would not only address the limitations of hose connections but also broaden the application range of disc separators to meet the needs of more industrial fields. Summary of the Invention

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention provides a disc centrifuge with vibration reduction and noise reduction to solve the above-mentioned problems.

[0007] The utility model provides a disc centrifuge with vibration reduction and noise reduction, comprising a base, a centrifuge body being arranged on the base, a shock-absorbing bracket being arranged on the base, a motor base being arranged on the shock-absorbing bracket, a drive motor being arranged on the motor base, a first shock-absorbing pad being arranged between the drive motor and the motor base, and a flexible coupling being arranged between the output shaft of the drive motor and the input shaft of the centrifuge body.

[0008] Furthermore, the motor seat is provided with a noise reduction shell covering the circumference of the driving motor, the inner wall of the noise reduction shell is provided with sound-absorbing cotton, the noise reduction shell is provided with a baffle at one end close to the output shaft, the baffle is provided with a shaft sleeve adapted to the output shaft, and the other end of the noise reduction shell is provided with a ventilation grille, the ventilation grille includes a frame adapted to the noise reduction shell, and a plurality of grilles with downward-inclined outer ends are provided at equal intervals from top to bottom in the inner frame of the frame, and a ventilation slot is provided between every two adjacent grilles.

[0009] Furthermore, the grid plate is a sound-absorbing plate.

[0010] Furthermore, the height of the outer end of the grid plate above each ventilation slot is lower than the inner end of the grid plate below.

[0011] Furthermore, a second shock-absorbing pad is provided at the bottom of the base. The second shock-absorbing pad is a rubber pad, and a plurality of anti-slip grooves with equal intervals are provided at the bottom of the rubber pad.

[0012] Furthermore, the flexible coupling is a belt coupling.

[0018] In order to better understand the present invention, Figures 1 to 3 The embodiments of the present invention will be explained in detail.

[0019] It should be noted that the directions “front, back, left, right, up, down” mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up and down” are used as the reference.

[0020] The utility model discloses a disc centrifuge with vibration reduction and noise reduction, comprising a base 1, and a centrifuge body 2 is fixed to one side of the top of the base 1, and a shock-absorbing bracket 3 is fixed to the other side. A motor base 4 is fixed to the top of the shock-absorbing bracket 3, which absorbs and disperses the vibration from the drive motor 5 through its elastic properties, thereby reducing the impact of the vibration on the base 1 and the surrounding environment. A drive motor 5 is mounted on the motor base 4. In order to further isolate the vibration, a first shock-absorbing pad 6 is provided between the drive motor 5 and the motor base 4. The shock-absorbing pad is made of a highly elastic material, such as rubber or silicone, to effectively reduce the transmission of motor vibration to the motor base 4.

[0021] The output shaft of the drive motor 5 is connected to the input shaft of the centrifuge body 2 through a flexible coupling 7. The flexible design of the flexible coupling 7 can compensate for the slight deviation between the two shafts, while isolating and reducing the impact of motor vibration on the operating stability of the centrifuge body 2. Figure 1 As shown in , the flexible coupling 7 is preferably a belt coupling.

[0022] To reduce the noise of the drive motor 5, the motor base 4 is covered with a noise-reducing housing 8, which completely surrounds the drive motor 5. At one end, near the output shaft, the housing 8 is equipped with a baffle with a bushing to support smooth rotation of the output shaft. A ventilation grille 10 is installed at the other end of the housing 8 to ensure that the motor's heat dissipation requirements are met. The inner wall of the housing 8 is lined with sound-absorbing cotton 9 to absorb the noise generated by the motor's operation, forming a soundproof barrier.

[0023] like Figure 3 As shown in FIG, the ventilation grille 10 includes a frame 11, and the inner frame of the frame 11 is evenly spaced with a plurality of grid plates 12 with outer ends tilted downward. A ventilation slot 13 is formed between every two grid plates 12 to facilitate air circulation.

[0024] To enhance noise reduction, sound-absorbing panels can be used for the gratings 12. Each pair of adjacent gratings 12 is tilted at a certain angle, ensuring that the outer end of the grating 12 above each ventilation slot 13 is lower than the inner end of the grating 12 below. This tilted design helps guide noise upward, reducing the amount of noise transmitted back into the centrifuge body 2 or the surrounding environment.

[0025] A second shock-absorbing pad 14 is provided at the bottom of the base 1. The second shock-absorbing pad 14 is a rubber pad, and a plurality of equally spaced anti-slip grooves 15 are provided at the bottom of the rubber pad. The second shock-absorbing pad 14 prevents the base 1 from rigidly contacting the ground and reduces vibration noise.

[0026] The usage and principle of this utility model:

[0027] First, place the centrifuge on a stable work surface to ensure that the base 1 is stable and does not shake.

[0028] Then, the drive motor 5 is started, which drives the centrifuge body 2 to rotate through the flexible coupling 7 to perform material separation. During this process, the shock-absorbing bracket 3 and the first shock-absorbing pad 6 will effectively absorb and disperse the vibration of the drive motor, reducing the vibration level of the entire equipment.

[0029] During this period, the noise reduction shell 8 and the sound-absorbing cotton 9 inside it will work together to reduce the noise output when the motor is running, providing a quieter working environment for the operator.

[0030] Finally, after the separation work is completed, the drive motor 5 is turned off, and the centrifuge is cleaned and maintained according to the normal operating procedures to ensure its long-term stable operation.
