Description

Technical Field

[0001] The utility model relates to the technical field of floor shock absorbers, in particular to a high-reliability floor shock absorber for a large disc separator. Background Technique

[0002] A disc separator is a high-speed sedimentation centrifuge that rapidly separates mixtures such as "liquid-solid" and "liquid-liquid-solid" by the powerful centrifugal force generated by high-speed rotation. Due to its high separation efficiency and high degree of automation, it can realize full-automatic operation from feeding, separation, slag discharging and other steps, and is widely used in industries such as ships, food, medicine, chemical industry, textile and environmental protection.

[0003] The high-speed rotation of the disc separator and other factors will cause certain vibrations in the equipment itself. Therefore, rubber shock absorbers are usually installed at the bottom of the machine base of the disc separator to reduce the impact of the vibration of the separator itself on the surrounding equipment. This is even more important for large-scale disc separators. The rotor of large-scale separators is heavy, and the vibration of the equipment itself will also increase. Therefore, appropriate shock absorbers must be installed at its bottom to reduce its impact on the surrounding equipment and the ground.

[0004] The existing shock absorbers are made of rubber pads with a certain hardness. As Figure 1 shown, after being used for a period of time, when the rubber deforms and ages, it needs to be replaced. When replacing, the pipelines around the machine need to be removed first, and then the whole machine needs to be lifted. According to statistics, the service life of the existing shock absorbers is usually about half a year, and it takes two people half a day to replace them once. It is time-consuming and laborious, affecting normal production. Content of the Utility Model

Specific implementation mode

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] Embodiment 1: Please refer to Figures 2 - 10 , the present utility model provides a technical solution: a shock absorber for the feet of a highly reliable large disc separator, including: a bottom stud 1 and a shock absorber base 2. The bottom stud 1 is provided in the center of the shock absorber base 2, the shock absorber cover 4 is provided on the top of the shock absorber base 2, the first rubber pad 6 is provided in the center of the top of the shock absorber base 2, the first rubber pad 6 is located inside the shock absorber cover 4, the shock absorber partition 5 is provided on the top of the first rubber pad 6, a flange is provided in the middle of the shock absorber partition 5, the second rubber pad 7 is provided above the flange, the inner wall of the top of the shock absorber cover 4 presses above the second rubber pad 7, the central bolt 15 is provided in the center of the shock absorber partition 5, the protective cover 11 is provided on the top of the shock absorber cover 4, and the nut 16 is provided above the protective cover 11 on the outside of the central bolt 15. After installation, under the weight of the separator, the first rubber pad 6 is compressed to play a main shock-absorbing role, while the second rubber pad 7 plays an auxiliary shock-absorbing role; after being used for a period of time, the first rubber pad 6 produces permanent deformation, and when it exceeds 2 mm, at this time, both the first rubber pad 6 and the second rubber pad 7 are compressed and both play a shock-absorbing role. When both the first rubber pad 6 and the second rubber pad 7 are aged, it is only necessary to replace the rubber pads inside the shock absorber. In addition, the rubber pads inside the original shock absorber and the new shock absorber are completely inside and are not easily polluted by the outside, which can also improve the service life.

[0032] The hardness of the second rubber pad 7 is usually about 10 Shore degrees higher than that of the first rubber pad 6. The shock absorber is fixed to the separator base through bolts and nuts 16, and the shock absorber is fixed to the installation base through the bottom stud 1 below. Before installation, the hardness of the rubber pads is usually selected according to the weight and operating conditions of the separator equipment.

[0033] The shock absorber base 2 and the shock absorber cover 4 are connected by hexagon socket head cap screws 3. There are several threaded holes at the bottom of the shock absorber cover 4 that cooperate with the hexagon socket head cap screws 3. Connecting the shock absorber cover 4 and the shock absorber base 2 by using the hexagon socket head cap screws 3 and the corresponding threaded holes not only provides a stable mechanical connection but also facilitates disassembly and maintenance. For example, if it is necessary to replace the rubber pad or other internal components, the operator can easily remove the hexagon socket head cap screws 3 and open the shock absorber cover 4 for inspection or replacement work. After the maintenance is completed, the hexagon socket head cap screws 3 can be reinstalled to restore the shock absorber to its normal operating state.

[0034] The flange bottom surface of the shock absorber partition 5 abuts against the first rubber pad 6, and the top surface of the shock absorber partition 5 is flush with the top surface of the shock absorber cover 4. The shock absorber partition 5 is directly placed on the first rubber pad 6, enabling the force transmitted from above to be evenly distributed to the first rubber pad 6, thereby achieving an effective shock absorption effect.

[0035] A rubber seat 8 is provided at the top of the shock absorber cover 4. A centering disc 9 is provided on the outside of the rubber seat 8. A backing plate 10 is provided above the centering disc 9. A protective cover 11 is located above the backing plate 10. An upper connecting ring 13 is provided on the inner wall of the top of the protective cover 11. A serrated pressing block 14 is provided at the bottom of the upper connecting ring 13. A retaining ring 12 is provided below the serrated pressing block 14 at the top of the centering disc 9. The top surface of the retaining ring 12 is provided with anti-slip threads. The retaining ring 12 is located above the edge of the centering disc 9, and the top of the retaining ring 12 abuts against the bottom of the serrated pressing block 14. The centering disc is used to ensure that the separator can be accurately centered during installation. This design helps to ensure the balance of the separator during operation, reduce the additional vibration caused by eccentricity, and enable the first rubber pad 6 and the second rubber pad 7 to be more evenly stressed through the shock absorption and guiding effects of the centering disc 9 and the rubber seat 8, avoiding accelerated damage caused by local wear. Through the close cooperation between the retaining ring 12 and the serrated pressing block 14, the stability of the entire shock absorber is ensured.

[0036] The middle part of the rubber seat 8 is cylindrical. A flange edge is provided at the bottom of the rubber seat 8. The outer diameter of the flange edge is the same as the outer diameter of the shock absorber cover 4. A through hole for the central bolt 15 to pass through is provided in the center of the rubber seat 8. There is a gap between the bottom surface of the protective cover 11 and the ground of the shock absorber base 2. This is used to leave space for the elastic deformation of the rubber pad.

[0037] A relief hole is provided at the center of the top of the shock absorber base 2 below the head of the central bolt 15. The relief hole is used to facilitate the installation of the central bolt 15. The centering disc 9 is in the shape of a disc with a convex middle part. A through hole for the central bolt 15 to pass through is provided in the center of the centering disc 9. A lower flange is provided at the bottom of the centering disc 9. The outer diameter of the lower flange is the same as the outer diameter of the shock absorber cover 4. This facilitates uniform stress.

[0038] Through the shock absorber base, shock absorber cover and shock absorber partition provided by the utility model, the whole floor shock absorber is installed on the floor of the large butterfly separator. After installation, under the weight of the separator, the first rubber pad 6 is compressed to play a major shock absorption role, while the second rubber pad 7 plays an auxiliary shock absorption role. After being used for a period of time, the first rubber pad 6 produces permanent deformation. When it exceeds 2 mm, at this time, both the first rubber pad 6 and the second rubber pad 7 are compressed and both play a shock absorption role. When both the first rubber pad 6 and the second rubber pad 7 are aged, it is only necessary to replace the rubber pads inside the shock absorber. In addition, the rubber pads inside the original shock absorber and the new shock absorber are completely inside, not easily polluted by the outside world, and can also improve the service life.

[0039] In addition, during the use of the shock absorber, through the shock absorption and guiding effects of the positive heart socket plate 9 and the rubber seat 8, the forces on the first rubber pad 6 and the second rubber pad 7 can be made more uniform, avoiding accelerated damage caused by local wear. After actual use, after adopting this technical solution, the replacement cycle of the floor shock absorber of the separator is extended from 6 months to more than 18 months, and the reliability is increased by more than 2 times.

[0040] Example 2: When the large disc separator (drum outer diameter 1000 mm) uses the original shock absorber, the vibration around the bottom of the equipment increases after 6 months; after using the new shock absorber, the hardness of the rubber pad 1 is Shore A85 degrees, and the rubber pad 2 is Shore A75 degrees. After 18 months of use, the equipment can still run smoothly. The reliability of its shock absorber is increased by more than 2 times.

[0041] Example 3: When the large disc separator (drum outer diameter 900 mm) uses the original shock absorber, the vibration around the bottom of the equipment increases after 7 months; after using the new shock absorber, the hardness of the rubber pad 1 is Shore A70 degrees, and the rubber pad 2 is Shore A60 degrees. After 20 months of use, the equipment can still run smoothly. The reliability of its shock absorber is increased by more than 2 times.

[0042] Example 4: When the large disc separator (drum outer diameter 800 mm) uses the original shock absorber, the vibration around the bottom of the equipment increases after 6 months; after using the new shock absorber, the hardness of the rubber pad 1 is Shore A65 degrees, and the rubber pad 2 is Shore A56 degrees. After 24 months of use, the equipment can still run smoothly. The reliability of its shock absorber is increased by more than 3 times.

[0043] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
