Description

Technical Field

[0001] The utility model relates to the technical field of polishing liquid filtering and circulating treatment devices, and more specifically, to a polishing liquid filtering and circulating treatment device. Background Art

[0002] In the existing polishing liquid filtering and circulating treatment device technology, flow control is a key factor, which directly affects the stability and service life of the filtration system. However, the existing polishing liquid filtering and circulating treatment device has certain shortcomings when processing large flows, which brings potential risks to practical applications.

[0003] First, the existing polishing liquid filtration circulation treatment device often fails to fully consider the impact of large flow on the filter shell in design. In actual use, if the inflow flow is too large, it may cause the filter shell to be subjected to excessive pressure, resulting in damage. Since the existing equipment lacks effective flow control measures in design, such as the lack of flow regulating valves or flow limiting devices, the filter shell is easily damaged when facing large flow. This not only reduces the stability and reliability of the filtration system, but may also cause leakage or contamination of the polishing liquid, affecting the use effect.

[0004] Secondly, the existing polishing liquid filtration circulation treatment device has certain deficiencies in pressure relief. Since the filter shell is easily damaged when facing large flow, an effective pressure relief mechanism is needed to relieve the pressure. However, the existing equipment may lack an effective pressure relief device or have insufficient pressure relief capacity, resulting in the inability to relieve pressure in time when the flow is too large, thereby increasing the risk of damage to the filter shell. This not only affects the normal operation of the filtration system, but may also cause equipment failure or shutdown, affecting production efficiency and product quality. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a polishing liquid filtering and circulating treatment device, which has the following beneficial effects:

[0018] 1. The design of the pressure relief mechanism enables the polishing liquid filtration circulation treatment device to effectively cope with the situation of excessive flow and prevent the filter shell from being damaged due to excessive pressure. Through the cooperation of the connecting mechanism, pressure relief pipe, one-way pipe, adjustment mechanism, one-way disk, external pipe, sealing ring, sealing pipe and threaded sleeve, the pressure relief mechanism can automatically open when the polishing liquid pressure exceeds the set value and discharge the excess liquid through the external pipe, thereby protecting the filtration system from damage. This design improves the stability and durability of the device and ensures the continuity and reliability of the polishing liquid filtration process.

[0019] 2. The design of the regulating mechanism enables the operator to flexibly adjust the opening pressure of the pressure relief mechanism according to the flow and pressure requirements of the polishing liquid. Through the cooperation of the insertion rod, follower sleeve, push plate and spring, the regulating mechanism can change the compression of the spring by turning the pull plate, thereby adjusting the sealing state between the one-way disk and the one-way tube to achieve precise control of the pressure relief pressure. This design provides a convenient operation method, enables the device to adapt to different working conditions, optimizes the performance of the filtration system, and reduces maintenance costs.

[0020] 3. The design of the connecting mechanism ensures that the polishing liquid can flow smoothly into and out of the filtering circulation treatment device. Through the setting of the feed pipe and the discharge pipe, the connecting mechanism realizes the circulation of the polishing liquid. At the same time, the configuration of the filter shell ensures the effective removal of impurities in the polishing liquid. This design not only improves the filtration efficiency, but also ensures the stability and sealing of the filter shell through the setting of the flange and the top block.

A sealing groove 9 is provided in the sealing tube 7, and the sealing ring 6 is inserted into the sealing groove 9. A threaded sleeve 8 is installed on the sealing tube 7, and the threaded sleeve 8 is threadedly connected in the one-way tube 3. A telescopic rod 10 is provided on the one-way disk 4, and the telescopic rod 10 is slidably connected in the threaded sleeve 8. A pull plate 11 is coaxially provided on the telescopic rod 10. The adjusting mechanism includes an insertion rod 12 and a follower sleeve 13, and the insertion rod 12 is installed on the one-way disk 4. The follower sleeve 13 is slidably connected to the insertion rod 12. A threaded ring 14 is provided on the inner thread of the one-way tube 3, and the threaded ring 14 is connected to the follower sleeve 13. A push plate 15 is provided on the insertion rod 12, and a spring 16 is provided on the push plate 15, and the spring 16 abuts against the follower sleeve 13.

[0031] In this embodiment, when filtering the polishing liquid, the polishing liquid is first introduced through the feed pipe 18, and then filtered through the filter shell 19. The filtered polishing liquid is discharged through the discharge pipe 17. When the flow rate of the polishing liquid is too large, it will flow into the pressure relief pipe 2. When the pressure of the polishing liquid exceeds the elastic force of the spring 16, the one-way disk 4 will release the seal with the one-way tube 3, and then be discharged through the external tube 5, thereby avoiding damage caused by excessive pressure.

[0032] See also Figure 1 and Figure 2 As an implementation of the connecting mechanism: the connecting mechanism includes a discharge pipe 17 and a feed pipe 18, one end of the feed pipe 18 is connected to the outer shell 1, and the other end of the feed pipe 18 is connected to the external equipment, the discharge pipe 17 is installed on the outer shell 1, the discharge pipe 17 is connected to the external equipment, and a filter shell 19 is connected to the discharge pipe 17, the filter shell 19 and the outer shell 1 are coaxially arranged, a flange 20 is provided on the outer shell 1, and a top block 21 is provided on the flange 20, and the top block 21 abuts against the filter shell 19.

[0033] More specifically, when the pressure of the pressure relief needs to be adjusted, the pull plate 11 is first rotated to drive the insertion rod 12 to rotate. Since the follower sleeve 13 is rotatably connected to the insertion rod 12, the follower sleeve 13 and the threaded ring 14 are driven to rotate. The threaded ring 14 and the one-way tube 3 are threaded, so the position can be adjusted, and then the compression amount of the spring 16 is changed, thereby changing the elastic force of the spring 16, so the pressure of the pressure relief can be changed. When the pressure relief is not needed, since the threaded sleeve 8 is threadedly connected to the one-way tube 3, the sealing tube 7 is abutted against the upper end of the one-way disk 4, thereby completing the sealing process.

[0034] In summary, when the overall equipment is in use or running: when filtering the polishing liquid, the polishing liquid is first introduced through the feed pipe 18, and then filtered through the filter shell 19, and the filtered polishing liquid is discharged through the discharge pipe 17. When the flow rate of the polishing liquid is too large, it will flow into the pressure relief pipe 2. When the pressure of the polishing liquid exceeds the elastic force of the spring 16, the one-way disk 4 will release the seal with the one-way tube 3, and then be discharged through the external tube 5, thereby avoiding damage caused by excessive pressure.

[0035] When the pressure of the pressure relief needs to be adjusted, first the pull plate 11 is rotated, which will then drive the insertion rod 12 to rotate. Since the follower sleeve 13 is rotatably connected to the insertion rod 12, the follower sleeve 13 and the threaded ring 14 will be driven to rotate. The threaded ring 14 and the one-way tube 3 are threaded, so the position will be adjusted, and then the compression amount of the spring 16 will change, thereby changing the elastic force of the spring 16, so the pressure of the pressure relief can be changed. When the pressure relief is not needed, since the threaded sleeve 8 is threadedly connected to the one-way tube 3, the sealing tube 7 will contact the upper end of the one-way disk 4, thereby completing the sealing process.

In the above, all fixed connections are preferably welded.
