Description

Technical Field

[0001] This utility model relates to the technical field of centrifuge vibration damping devices, and in particular to a vibration damping device for a vertical scraper discharge centrifuge. Background Technology

[0002] A vibration damping device for a vertical scraper discharge centrifuge is a component designed to reduce the vibration generated during centrifuge operation. It is mainly used in vertical scraper discharge centrifuges. By absorbing and buffering vibration energy, it reduces the impact of the centrifuge on the foundation and surrounding equipment, thereby improving the stability and service life of the equipment.

[0003] The vibration damping device mainly consists of components such as spring sleeves, anchor beams, spring bolts, rubber spring one, rubber spring two, spring pressure plates, spring washers, inclined washers, nuts, moving plates, and limiting plates. The spring sleeves are installed inside the round holes of the centrifuge base, and the anchor beam is located below the spring sleeves. The spring bolts pass through the through holes of both the spring sleeves and the anchor beam, connecting and fixing them together. Rubber spring one is mounted on the spring bolts, with its bottom surface abutting against the upper surface of the centrifuge base to achieve vibration damping.

[0004] In terms of structural design, due to the tight connection of various components and the relatively fixed installation position, if a component in the shock absorption structure, such as a spring or rubber pad, is damaged and needs to be replaced, the operating space is limited, the replacement is difficult, and many related components need to be disassembled for replacement, which is time-consuming and labor-intensive. Furthermore, after long-term use, the connections between various components may become loose due to vibration, which further increases the complexity and difficulty of maintenance and replacement, leading to increased equipment maintenance costs and downtime, and affecting production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a shock absorption device for a vertical scraper discharge centrifuge, which aims to improve the problem that when damage occurs and replacement is needed, the operating space is limited and many related parts need to be disassembled for replacement, which is time-consuming and labor-intensive.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a shock-absorbing device for a vertical scraper discharge centrifuge, comprising a receiving plate, short columns fixedly connected to the four corners of the bottom wall of the receiving plate, a spring fixedly connected to the four corners of the bottom wall of the receiving plate, limit blocks fixedly connected to the four corners of the receiving plate, connecting plates provided on both sides of the bottom wall of the receiving plate, connecting columns fixedly connected to the opposite surfaces of the connecting plates, two sets of long plates fixedly connected to both sides of the bottom wall of the receiving plate, bolts fixedly connected to the opposite surfaces of the two sets of long plates, two sets of shock-absorbing components installed between the long plates and the connecting columns, and quick-release mechanisms fixedly connected to the four corners of the top wall of the receiving plate, the quick-release mechanisms being used for quick disassembly of the shock-absorbing device.

[0007] As a preferred embodiment of this utility model, the quick-release mechanism includes a fixing block and a cylinder. A locking block is fixedly connected to the top wall of the cylinder, and a round cap block is fixedly connected to the top wall of the locking block.

[0012] As a preferred embodiment of this utility model, a triangular block is fixedly connected to one end of the long column, and a spring is installed on the outer wall of the long column.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when the centrifuge is working, the receiving plate is subjected to vibration. The corner spring first absorbs energy and slows down the vibration. The shock absorption components on both sides of the bottom wall are linked. The connecting block changes angle to make the long plate and sliding column move. The spring second extends and retracts to eliminate vibration. Multiple components form a multi-dimensional shock absorption system. The limit block ensures that the spring first works normally, reduces the amplitude and stabilizes the operation, which is beneficial to the stability of the system and improves the reliability and life of the equipment.

In this utility model, the quick-release mechanism between the shock-absorbing device and the centrifuge involves the fixing block and the cylinder approaching each other during installation, causing the cylinder to move outward and the spring to stretch three times. After the components are in place, the triangular block rebounds and engages with the round cap block to complete the connection. During disassembly, pressing the fixing block and using the special shape of the triangular block, the cylinder can be pulled outward to detach. Attached Figure Description

[0022] 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 protection scope of the present utility model.

[0023] Reference Figures 1 to 4 This utility model provides an embodiment of a vertical scraper discharge centrifuge vibration damping device, including a receiving plate 1. Short columns 3 are fixedly connected to the four corners of the bottom wall of the receiving plate 1, springs 4 are fixedly connected to the four corners of the bottom wall of the receiving plate 1, and limiting blocks 5 are fixedly connected to the four corners of the receiving plate 1. Connecting plates 15 are provided on both sides of the bottom wall of the receiving plate 1, and connecting columns 10 are fixedly connected to the opposite surfaces of the connecting plates 15. The receiving plate 1 is a key force-bearing and connecting component. The short columns 3 on its bottom wall provide positioning and extension guidance for the springs 4. The springs 4 absorb vibration energy, and the limiting blocks 5 limit the deformation range of the springs 4 to ensure stability. The connecting plates 15 and connecting columns 10 form the basic framework for the installation and operation of subsequent vibration damping components, which is conducive to coordinated vibration damping.

[0024] Two sets of long plates 6 are fixedly connected to both sides of the bottom wall of the receiving plate 1. Bolts 7 are fixedly connected to the opposite surfaces of the two sets of long plates 6. Two sets of shock-absorbing components are installed between the long plates 6 and the connecting column 10. Quick-release mechanisms 2 are fixedly connected to the four corners of the top wall of the receiving plate 1. Quick-release mechanisms 2 are used to quickly disassemble the shock-absorbing device. The shock-absorbing component includes a connecting block 8. The top of the connecting block 8 is rotatably connected to the outer wall of the bolt 7. The two sets of long plates 6 and the bolt 7 form a stable connection structure, providing a support for the installation of the shock-absorbing component. The top of the connecting block 8 is rotatably connected to the bolt 7, so that the connecting block 8 can flexibly change its angle during vibration, thereby driving the movement of related components and activating the shock-absorbing component. The quick-release mechanism 2 facilitates the rapid separation of the shock-absorbing device in situations such as equipment maintenance, improving operational convenience and efficiency.

[0025] Bolt 16 is rotatably connected to the bottom of connecting block 8. Long plate 9 is fixedly connected to both ends of bolt 16. Sliding column 11 is fixedly connected to the bottom wall of long plate 9. Sliding column 11 is slidably connected to the outer wall of connecting column 10. Spring 12 is fixedly connected to the opposite surfaces of the two sliding columns 11. Spring 4 is installed on the outer wall of short column 3. Limiting block 5 is set on one side of spring 4. The bottom of connecting block 8 is rotatably connected to bolt 16, so that long plate 9 can move in conjunction with connecting block 8. Sliding column 11 on the bottom wall of long plate 9 slides on the outer wall of connecting column 10, providing guidance for the extension and retraction of spring 12. Spring 12, with the help of sliding column 11 and connecting column 10, extends and retracts to buffer vibration. Spring 4, short column 3 and limiting block 5 together absorb and limit vibration, stabilizing the equipment.

[0026] The quick-release mechanism 2 includes a fixing block 204 and a cylinder 201. A locking block 202 is fixedly connected to the top wall of the cylinder 201, and a round cap block 203 is fixedly connected to the top wall of the locking block 202. Locking components are installed on both sides of the interior of the fixing block 204. The cylinder 201 and its locking blocks 202 and round cap blocks 203 cooperate with the fixing block 204. During installation, a specific locking action is used to achieve a stable connection with the locking components, connecting the centrifuge equipment 14 and the shock absorber as one unit. When disassembly is required, the connection can be quickly released, facilitating maintenance, repair, or replacement of the shock absorber or centrifuge equipment 14.

[0027] The top wall of the fixing block 204 is fixedly connected to the base plate 13, and the top of the base plate 13 is fixedly connected to the centrifuge device 14. The locking assembly includes a long column 206 and a locking disc 205. The locking disc 205 is fixedly connected to one end of the long column 206, and a triangular block 208 is fixedly connected to one end of the long column 206. A spring 3 207 is installed on the outer wall of the long column 206. The base plate 13 is used to connect the fixing block 204 and the centrifuge device 14 to realize the construction of the overall structure. In the locking assembly, the locking disc 205 works in conjunction with the long column 206 and the triangular block 208. With the help of the elastic force of the spring 3 207, the triangular block 208 is locked with the round cap block 203 during installation to achieve fixation. During disassembly, the triangular block 208 is disengaged by pressing or other operations to achieve the purpose of quick disassembly and assembly.

[0028] Working principle: When the centrifuge vibrates during operation, the receiving plate 1, as the directly stressed component, begins to vibrate. Springs 4 at the four corners respond first to the vibration, extending and retracting along the short column 3. Their elastic deformation absorbs some of the vibration energy, initially mitigating the impact. Simultaneously, the damping components on both sides of the bottom wall of the receiving plate 1 work together. Since the top of the connecting block 8 is rotatably connected to bolt 7 and the bottom to bolt 16, the angle of the connecting block 8 changes under vibration, causing the long plate 9 and its bottom sliding column 11 to slide on the outer wall of the connecting column 10. During this process, spring 12 is stretched or compressed, generating a force opposite to the direction of vibration, further reducing the vibration. The two sets of long plates 6... The shock absorption assembly, consisting of bolt 7, connecting block 8, long plate 9, bolt 16, sliding column 11, and spring 12, disperses and absorbs vibrations from different directions. Together with spring 4, it forms a multi-dimensional shock absorption system. Limiting block 5 ensures that spring 4 works within its elastic limit, preventing excessive deformation or displacement. Through the close cooperation of these components, the vibration energy generated by the centrifuge is converted into the elastic potential energy of the spring and gradually dissipated, effectively reducing the vibration amplitude transmitted to the outside, ensuring the stable operation of the centrifuge and reducing the impact on the surrounding environment and equipment. This allows the entire working system to operate continuously in a relatively stable state, meeting the requirements of production processes for equipment stability and improving the reliability and service life of the equipment.

[0029] Furthermore, a quick-release mechanism 2 is installed between the shock-absorbing equipment and the centrifuge device. During installation, when the fixing block 204 and the cylinder 201 approach each other for engagement, as they gradually approach, the round cap block 203 on the top of the cylinder 201 will collide with the triangular block 208 inside the fixing block 204. Due to the impact force, the triangular block 208 will drive the cylinder 201 to move outward a certain distance. At this time, the spring 3 207 is stretched. As the engagement continues, after the positions of each component are aligned, under the elastic restoring force of the spring 3 207, the triangular block 208 will move inward again, thus engaging under the round cap block 203, achieving a firm connection between the fixing block 204 and the cylinder 201, thereby securing the base plate. Centrifuge 14 and its mounting are stably installed in place. When disassembly is required, pressing the fixing block 204 will cause the triangular block 208 to engage further with the locking block 202 under pressure. Because one side of the triangular block 208 is W-shaped, its special shape design allows the triangular block 208 to smoothly disengage from under the round cap block 203 when the cylinder 201 is pulled out again, releasing the limiting relationship between the two and thus achieving quick disassembly. The entire quick-release mechanism 2, through its ingenious mechanical structure design and the assistance of springs, can conveniently complete the installation and disassembly of the centrifuge 14, improving the efficiency of equipment maintenance, repair and replacement, reducing downtime, and facilitating the efficient operation of the production process.
