Description

Technical Field

[0001] This utility model relates to the field of centrifuge base technology, and in particular to a centrifuge shock-absorbing and noise-reducing base. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids. It can also be used to remove liquid from wet solids, such as in a washing machine to spin-dry wet clothes. In general, a centrifuge is a machine that uses centrifugal force to accelerate the separation of different materials. It is now widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment, and shipbuilding industries. To reduce the impact force transmitted from the ground to the centrifuge during operation, a base is often installed on the ground before installation to reduce the upward impact force from the ground.

[0003] For example, patent application number CN201920498064.7 discloses a centrifuge mounting base, including a base, a shock-absorbing base fixedly mounted on the upper surface of the base, a mounting plate above the shock-absorbing base, a buffer column fixedly mounted on the bottom center of the mounting plate via a fixing plate, and a fixing column fixedly mounted on the center of the inner bottom wall of the shock-absorbing base. The fixing column has sliding grooves on both sides of its inner wall, and a slider is slidably mounted between the two sliding grooves. Through the buffer column and the fixing column, the vibration force generated by the centrifuge during operation is effectively buffered. This type of mounting base uses a spring-loaded shock-absorbing structure to provide shock absorption support for the centrifuge. Besides the noise generated by the vibration of the casing and base, the internal components of the centrifuge also generate noise during operation. This noise is difficult to block by the external casing of the centrifuge, affecting the daily work of the operators. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a centrifuge vibration damping and noise reduction base, including a fixed base 1 and a support platform 2. The support platform 2 is placed above the fixed base 1, and a plurality of damping shock absorbers 9 for supporting the support platform 2 are provided between the fixed base 1 and the support platform 2.

[0022] The damping shock absorber 9 mainly includes a damping rod and a metal spring and a rubber sleeve set on the outside of the damping rod. When the vertical vibration generated by the centrifuge is transmitted to the support platform 2, the damping shock absorber 9 stores and releases elastic potential energy through the extension and contraction of the metal spring, and dissipates vibration energy through the friction between the damping rod and the rubber sleeve, so as to avoid the vibration being directly transmitted to the fixed seat 1, thereby achieving the purpose of vibration reduction and noise reduction. As a general component, the damping shock absorber 9 has many optional models, which will not be described in detail here.

[0023] Positioning seats 3 are provided on the left and right sides of the fixed seat 1. The positioning seats 3 are fixedly connected to the fixed seat 1. The support platform 2 is slidably disposed between the two positioning seats 3. A guide mechanism is provided at the connection between the positioning seats 3 and the support platform 2.

[0024] The positioning seat 3 forms a horizontal limiting frame for the support platform 2, which can limit the horizontal displacement of the support platform 2. The guide mechanism on the positioning seat 3 can further constrain the movement trajectory of the support platform 2, so that it only slides up and down with vibration in the vertical direction, ensuring that the support platform 2 is subjected to uniform force.

[0025] The corner of the fixed base 1 is provided with a plug-in plate 10. The plug-in plate 10 is fixedly installed on the left and right sides of the positioning base 3. Several first sound barrier plates 14 are stacked between two adjacent plug-in plates 10. Several sets of second sound barrier plates 15 are stacked between two adjacent plug-in plates 10. The first sound barrier plates 14 and the second sound barrier plates 15 are plugged and unplugged into the plug-in plate 10.

[0026] The first sound barrier panel 14 is installed between two adjacent plug-in panels 10 at the front and back, and the second sound barrier panel 15 is installed between two adjacent plug-in panels 10 on the left and right sides, forming a surround sound insulation structure that can further reduce the noise generated during the operation of the centrifuge. The sound barrier panels are assembled by plugging in, and the number of sound barrier panels can be increased or decreased according to the size and shape of the centrifuge, and the sound insulation height can be adjusted to improve the flexibility of use.

[0027] It is worth explaining in detail that the positioning seat 3 has a guide groove 5 on the side facing the support platform 2, and the left and right ends of the support platform 2 are inserted into the guide groove 5 and slidably connected to the guide groove 5.

[0028] The width of the guide groove 5 matches the thickness of the end of the support platform 2, which can form a vertical sliding constraint. When the support platform 2 moves up and down with vibration, the guide groove 5 will guide it to maintain a straight trajectory and avoid jamming or deviation.

[0029] Furthermore, the guiding mechanism includes a guide groove 6, which is located on the side of the positioning seat 3 away from the support platform 2. The guide groove 6 communicates with the guide recess 5. A slider 7 is provided inside the guide groove 6, and the slider 7 is slidably connected to the guide groove 6. The slider 7 is fixedly installed at both ends of the support platform 2. A spring 8 for supporting the slider 7 is provided inside the guide groove 6. The spring 8 is fixedly installed inside the guide groove 6 and fixedly connected to the lower end of the slider 7.

[0030] When the support platform 2 vibrates downward, it will cause the slider 7 to compress the spring 8. The spring 8 generates an upward elastic reaction force, which initially buffers the vibration impact. At the same time, the cooperation between the guide groove 6 and the slider 7 further restricts the horizontal displacement of the support platform 2, forming a double constraint with the guide groove 5.

[0031] Each of the two adjacent plug-in plates 10 has a first slot 11 on its opposite side. The left and right ends of the first sound barrier plate 14 are inserted into the first slot 11 and slidably connected to the first slot 11.

[0032] The two adjacent plug-in plates 10 are provided with second slots 12 on opposite sides. The left and right ends of the second sound barrier plate 15 are inserted into the second slots 12 and slidably connected to the second slots 12.

[0033] During installation, insert the left and right ends of the first sound barrier panel 14 into the corresponding first slot 11, and insert the two ends of the second sound barrier panel 15 into the corresponding second slot 12. The first slot 11 and the second slot 12 will constrain the sound barrier panel from both ends, ensuring that the sound barrier panels can be stacked stably.

[0034] In a preferred embodiment, the lower ends of the first sound barrier plate 14 and the second sound barrier plate 15 are provided with protrusions 16, and the tops of the first sound barrier plate 14 and the second sound barrier plate 15 are provided with positioning grooves 17 that cooperate with the protrusions 16.

[0035] When stacking sound barrier panels, the positioning groove 17 of the upper sound barrier panel will engage with the protrusion 16 of the lower sound barrier panel, thereby forming a positioning constraint in the vertical direction, preventing horizontal misalignment of the sound barrier panels after stacking, reducing the gap between the panels, and improving the sound absorption effect of the sound barrier panels.

[0036] Regarding support platform 2:

[0037] A rubber pad 4 is provided on the upper surface of the support platform 2, and the rubber pad 4 is fixedly connected to the support platform 2. Multiple bolt connecting ears 13 are provided on the outer side of the support platform 2, and the bolt connecting ears 13 are fixedly connected to the support platform 2. The bolt connecting ears 13 rigidly fix the centrifuge to the support platform 2 with bolts. The rubber pad 4 can buffer the contact vibration between the centrifuge and the support platform 2 through its own elastic deformation, thus protecting the bottom of the centrifuge.

[0038] How this application works:

[0039] The centrifuge is placed on the upper end of the support platform 2. The bolt connecting lugs 13 on the outer side of the support platform 2 are used to fix the centrifuge to the support platform 2 with bolts, thereby preventing the centrifuge from shifting during operation. When the centrifuge vibrates during operation, the support platform 2 is displaced by the vibration force, and its left and right ends slide along the guide grooves 5 of the positioning seat 3, while the slider 7 slides synchronously in the guide groove 6. When the slider 7 moves down, it compresses the spring 8. The elastic force of the spring 8 can offset part of the vibration force. In conjunction with the damping shock absorber 9 between the fixed seat 1 and the support platform 2, it further absorbs the vibration energy and reduces the transmission of vibration to the fixed seat 1 and the ground, thus achieving the effect of vibration reduction. The first sound barrier panel 14 is laid between two adjacent plug-in panels 10 at the front and rear, and the second sound barrier panel 15 is laid between two adjacent plug-in panels 10 on the left and right, forming a surround sound insulation structure, which can further reduce the noise generated by the centrifuge during operation. The sound barrier panels are assembled by plugging in, and the number of sound barrier panels can be increased or decreased according to the size and shape of the centrifuge, and the sound insulation height can be adjusted to improve the flexibility of use.
