Description

Technical Field

[0001] The invention relates to the technical field of filtration, in particular to a high-pressure filter for an online analyzer. Background Art

[0002] A high-pressure filter is a device used to filter high-pressure fluids. Its main function is to remove tiny particles and suspended matter in the fluid to ensure the cleanliness and safety of the fluid. The high-pressure filter uses a filter medium to block tiny particles and suspended matter in the fluid, preventing it from passing through the filter medium, thereby achieving a filtering effect. During the filtering process, the fluid will pass through the filter medium, and a film layer will gradually form on the surface of the filter medium. The film layer will hinder the speed at which the fluid passes through the filter medium, thereby forming a pressure difference between the inlet and outlet of the fluid. The high-pressure filter uses the principle of pressure difference to control the pressure difference between the inlet and outlet so that the speed at which the fluid passes through the filter medium remains unchanged, thereby ensuring the filtering effect and stability. High-pressure filters play an important role in various industries and fields. In actual applications, the specific structure and implementation of high-pressure filters may be adjusted according to different needs and application scenarios.

[0003] The existing high-pressure filter is easily clogged during the working process, which requires the device to stop running and replace the filter element, resulting in work suspension. At the same time, it is difficult to observe whether the high-pressure filter is clogged. At the same time, once the filter element is clogged, it needs to be replaced immediately.

When filtering the fluid, it enters the housing 2 from the first feed pipe 3 and contacts the outer side of the filter element 12. Impurities in the fluid are absorbed by the filter layer inside the filter element 12. Clean fluid enters the inside of the filter element 12 and flows out through the first discharge pipe 6 to obtain clean fluid. When the device works for a long time, the filter layer inside the filter element 12 absorbs too many impurities, causing the device to be blocked and the filtering efficiency to be reduced. Or, during filtering, impurities in the fluid adhere to the surface of the filter element 12, blocking the fluid from entering the filter element 12, reducing the filtering effect of the device and causing the fluid inside the device to accumulate. When too much fluid accumulates inside the device and the pressure inside the device is too high, the fluid enters the pressure valve 9 through the second feed pipe 11. The excessive pressure causes the fluid to squeeze the pressure plate 17 when it contacts the pressure plate 17, so that the pressure plate 17 squeezes the spring 16, causing the pressure plate 17 to move toward the inside of the squeezing tube 18. The fluid enters the spare filter tank 7 through the pressure valve 9, is filtered by the filter plate 19, enters the connecting ball 25 through the alarm pipe 8, and flows out of the clean fluid through the first discharge pipe 6, thereby avoiding the blockage of the filter element 12 and causing damage to the device due to excessive pressure, thereby protecting the device.

[0030] At the same time, when the fluid filtered from the spare filter tank 7 flows through the second discharge pipe 10, the fluid contacts and squeezes the connecting plate 21, driving the connecting plate 21 to rotate, driving the rotating column 22 to rotate, the connecting plate 21 rotates and squeezes the vibration ball 23, driving the connecting plate 21 to move, contacting the vibration plate 24, driving the vibration plate 24 to vibrate and make a sound, causing the device to sound an alarm, thereby achieving an early warning effect.

[0031] At the same time, the telescopic rod 5 extends, driving the scraper 14 to contact the outer surface of the filter element 12, thereby cleaning the impurities blocking the outer surface of the filter element 12, thereby increasing the service life of the device and saving resources.

[0032] At the same time, the cleaned filter element 12 resumes its filtering effect, so that the fluid is filtered from the filter element 12 again and flows out from the first discharge pipe 6, so that the pressure inside the second feed pipe 11 is reduced, which is not enough to push the pressure plate 17 to compress the spring 16, so that the pressure plate 17 returns to its original position, and the pressure plate 17 resumes the blocked state.

[0033] The filter element 12 is designed with a double layer and a filter layer is arranged inside. A plurality of holes are arranged on the filter element 12. One end of the second discharge pipe 10 is connected to the connecting ball 25, and the first discharge pipe 6 is connected to the connecting ball 25. The fluid flows from the holes arranged on the filter element 12 into the filter layer in the filter element 12, thereby filtering the fluid. At the same time, the filtered fluid flows out from the first discharge pipe 6 through the connecting ball 25.

[0034] The outer shell 2 is hollow in design, the interior of the filter element 12 is connected to the first discharge pipe 6, and a hole is designed on the top plate 4, the size of which is adapted to the telescopic rod 5. The fluid flowing in from the first feed pipe 3 enters the interior of the outer shell 2, enters the filter layer through the holes designed on the filter element 12, enters the interior of the filter element 12 through the second layer of holes, and then discharges the clean fluid from the first discharge pipe 6. At the same time, the telescopic rod 5 extends to push the scraper 14 to clean the outer surface of the filter element 12.

[0035] A groove is provided inside the base 1, and the groove has a thread. The outer shell 2 is fitted with the base 1 through the thread. When the extension of the telescopic rod 5 drives the scraper 14 to clean the outer surface of the filter element 12 and fails to improve the filtering efficiency of the device, the filter element 12 is replaced by rotating the outer shell 2 to restore the filtering effect of the device, thereby saving resources.

[0036] The scraper 14 is connected to the filter element 12 , and one end of the scraper 14 close to the filter element 12 is fully squeezed with the filter element 12 . The extension of the telescopic rod 5 drives the scraper 14 to move, thereby cleaning the outer surface of the filter element 12 .

[0037] The partition block 13 is designed with several openings, which are respectively connected to the second feed pipe 11 and the first discharge pipe 6. The partition block 13 blocks the fluid in the first feed pipe 3 from directly entering the filter element 12. At the same time, the holes on the partition block 13 allow the clean fluid inside the filter element 12 to enter the first discharge pipe 6 through the holes and flow out.

[0038] A filter plate 19 is arranged inside the spare filter tank 7. The filter plate 19 has a double-layer design and is provided with holes. The fluid flows into the spare filter tank 7 from the second feed pipe 11, is filtered through the filter plate 19 and enters the second discharge pipe 10, and enters the first discharge pipe 6 from the connecting ball 25 and flows out.

[0039] A limiting device is designed at one end of the alarm tube 8 close to the second discharge pipe 10, and the vibrating ball 23 is confined inside the alarm tube 8. The vibrating ball 23 is connected to the vibrating plate 24. The alarm tube 8 is provided with a device to limit the vibrating ball 23 from falling out, to prevent the vibrating ball 23 from escaping from the alarm tube 8 during vibration, and at the same time, to hit the vibrating plate 24 during vibration, so that the device sends out an alarm to remind the staff that the device is blocked.

[0040] The filter element 12 is provided with a separator plate 15, which is designed with an opening and has a size adapted to the telescopic rod 5. The separator plate 15 is connected to the housing 2. The separator plate 15 is provided on the filter element 12 to prevent the fluid in the device from escaping and causing damage to the device.

[0041] The size of the pressure plate 17 is adapted to the extrusion tube 18, so that when the pressure plate 17 is subjected to sufficient pressure, the pressure plate 17 enters the extrusion tube 18 through the extrusion spring 16, so that the fluid enters the second feed pipe 11 and is filtered through the spare filter tank 7, thereby avoiding blockage of the device and causing excessive pressure, which may cause damage to the device.

[0042] Working principle: When filtering fluid, it enters the housing 2 from the first feed pipe 3 and contacts the outside of the filter element 12. Impurities in the fluid are absorbed by the filter layer inside the filter element 12. Clean fluid enters the inside of the filter element 12 and flows out through the first discharge pipe 6 to obtain clean fluid. When the device works for a long time, the filter layer inside the filter element 12 absorbs too many impurities, causing the device to be blocked and the filtering efficiency to be reduced. Or, during filtering, impurities in the fluid adhere to the surface of the filter element 12 and block the fluid from entering the filter element 12, reducing the filtering effect of the device and causing the fluid to accumulate inside the device. When too much fluid accumulates inside the device and the pressure inside the device is too high, the fluid enters the pressure valve 9 through the second feed pipe 11. The excessive pressure causes the pressure plate 17 to be squeezed when the fluid contacts the pressure plate 17, so that the pressure plate 17 squeezes the spring 16, causing the pressure plate 17 to move toward the inside of the squeezing tube 18. The fluid enters the spare filter tank 7 through the pressure valve 9, is filtered by the filter plate 19, enters the connecting ball 25 through the alarm pipe 8, and flows out of the clean fluid through the first discharge pipe 6, thereby avoiding the blockage of the filter element 12 and causing damage to the device due to excessive pressure, thereby protecting the device.

[0043] At the same time, when the fluid filtered from the spare filter tank 7 flows through the second discharge pipe 10, the fluid contacts and squeezes the connecting plate 21, driving the connecting plate 21 to rotate, driving the rotating column 22 to rotate, the connecting plate 21 rotates and squeezes the vibration ball 23, driving the connecting plate 21 to move, contacting the vibration plate 24, driving the vibration plate 24 to vibrate and make a sound, causing the device to sound an alarm, thereby achieving an early warning effect.

[0044] At the same time, the telescopic rod 5 extends, driving the scraper 14 to contact the outer surface of the filter element 12, thereby cleaning the impurities blocking the outer surface of the filter element 12, thereby increasing the service life of the device and saving resources.

[0045] At the same time, the cleaned filter element 12 resumes its filtering effect, so that the fluid is filtered from the filter element 12 again and flows out from the first discharge pipe 6, so that the pressure inside the second feed pipe 11 is reduced, which is not enough to push the pressure plate 17 to compress the spring 16, so that the pressure plate 17 returns to its original position, and the pressure plate 17 resumes the blocked state.

[0046] The fluid flows into the filter layer in the filter element 12 through the holes set on the filter element 12, which has a filtering effect on the fluid. At the same time, the filtered fluid flows out from the first discharge pipe 6 through the connecting ball 25, and the fluid flowing in from the first feed pipe 3 enters the interior of the housing 2, enters the filter layer through the holes designed on the filter element 12, and then enters the interior of the filter element 12 through the second layer of holes, and then the clean fluid is discharged from the first discharge pipe 6. At the same time, the telescopic rod 5 is extended to push the scraper 14 to clean the outer surface of the filter element 12. When the extension of the telescopic rod 5 drives the scraper 14 to clean the outer surface of the filter element 12 and fails to improve the filtering efficiency of the device, the filter element 12 is replaced by rotating the housing 2 to restore the filtering effect of the device, which saves resources. The partition block 13 is used to block the second filter element 12. The fluid in a feed pipe 3 directly enters the filter element 12, and at the same time passes through the holes on the partition block 13, so that the clean fluid inside the filter element 12 enters the first discharge pipe 6 from the holes and flows out. The alarm tube 8 is provided with a device to limit the vibration ball 23 from falling out, so as to prevent the vibration ball 23 from escaping from the alarm tube 8 during vibration, and at the same time hits the vibration plate 24 during vibration, so that the device sends out an alarm to remind the staff that the device is blocked. The partition plate 15 is arranged on the filter element 12, which prevents the fluid in the device from escaping and causing damage to the device. The pressure plate 17 is made to enter the squeezing tube 18 through the squeezing spring 16, so that the fluid enters the second feed pipe 11 and is filtered through the spare filter tank 7 to avoid excessive pressure caused by blockage of the device and damage to the device.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
