Technical Field
[0001] This utility model relates to the field of disc filter technology, specifically a disc filter with a quick-release filter element. Background Technology
[0002] Disc filters are high-efficiency, automated filtration devices widely used in fluid processing and industrial fluid filtration. They intercept impurities and particulate matter in fluids through multiple layers of stacked filter discs. These discs typically have specific pore structures that can be selected according to different filtration requirements. During the filtration process, the fluid passes through the filter discs from the outside to the inside or from the inside to the outside, and impurities are trapped on the surface or inside of the filter discs. Disc filters feature high filtration accuracy, low pressure drop, and good backwashing effect. They can effectively remove suspended solids, particulate matter, colloids, and other impurities from fluids, ensuring fluid cleanliness and are suitable for various complex working conditions and fluid quality conditions. In the cleaning process of existing disc filters, disassembly and assembly are usually accomplished by rotating the spiral structure between the disc filter element and the filter. Although this design facilitates disassembly and assembly, relative movement occurs between the sealing ring and the sealing surface during installation. The friction generated by this movement causes the surface of the sealing ring to gradually wear. This wear not only reduces the sealing performance of the sealing ring but also easily shortens its service life, increases maintenance costs and equipment downtime. Therefore, a disc filter with a quick-release filter element is proposed to address the above problems. Utility Model Content

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.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-8 This utility model provides a technical solution: A disc filter with a quick-release filter element includes a stacked filter assembly 1 and a housing assembly 2. The housing assembly 2 is inserted into the inside of a filter assembly assembly 3. A pressure boosting assembly 4 is installed on the outside of the filter assembly assembly 3. An anti-detachment assembly 5 is inserted into the inside of the filter assembly assembly 3. The filter assembly assembly 3 includes a filter shell 31. A first rubber sealing ring 33 is fixedly connected to the top of the filter shell 31. A second rubber sealing ring 35 is fixedly connected to the inside of the filter shell 31. A retaining ring 37 is fixedly connected to the outside of the filter shell 31. A column hole 38 is opened on the inside of the filter shell 31. The pressure boosting assembly 4 includes a spring 41. An annular slide 42 is fixedly connected to the bottom of the spring 41. A column cylinder 43 is fixedly connected to the inside of the annular slide 42. A third rubber sealing ring 44 is fixedly connected to the upper part of the column cylinder 43. A duckbill valve 45 is fixedly connected to the inner side of the column cylinder 43 near the lower end.
[0017] As a further implementation of this solution, the stacked filter assembly 1 includes a stacked filter element 11. A ring seat 12 and two positioning plates 13 are fixedly connected to the outside of the stacked filter element 11. The positioning plates 13 extend to the bottom end of the stacked filter element 11 and are located at the lower end of the ring seat 12. The two positioning plates 13 are distributed at the front and rear ends of the stacked filter element 11. The positioning plates 13 slide inside the guide groove 34. The stacked filter element 11 is inserted into the inner side of the assembly port 32. Through the above configuration, this structural design not only enhances the overall stability of the device, but also ensures the smooth movement of the stacked filter element 11 inside the assembly port 32 through the sliding connection of the positioning plates 13, improving the convenience of installation and disassembly, reducing wear on the sealing mechanism caused by torsion, and extending the service life of the sealing structure. As a further implementation of this solution, both the assembly port 32 and the guide groove 34 are located inside the filter housing 31. Two channels are provided inside the filter housing 31, and both channels extend upward to the assembly port 32. The channel near the middle of the filter housing 31 is located inside the second rubber sealing ring 35 and extends backward to communicate with the outlet pipe. The channel near the front of the filter housing 31 is located outside the second rubber sealing ring 35 and extends forward to communicate with the inlet pipe. Through the above arrangement, this channel design not only optimizes the flow path of the fluid and ensures the smooth passage of the fluid, but also effectively prevents the fluid from directly entering the middle channel from between the stacked filter element 11 and the filter housing 31 through the sealing effect of the second rubber sealing ring 35, avoiding the short-circuiting phenomenon of the fluid, thereby significantly improving the filtration effect and enhancing the reliability and stability of the device. As a further implementation of this solution, the top of the first rubber sealing ring 33 is tightly attached to the bottom of the expansion plate 23. A protective cover 21 is fixedly connected to the top of the expansion plate 23, and two inserts 6 are fixedly connected to the bottom of the protective cover 21. The inserts 6 can be inserted into the inside of the column hole 38. Through the above arrangement, this design ensures good sealing performance and prevents fluid leakage by ensuring the tight contact between the first rubber sealing ring 33 and the expansion plate 23. At the same time, the insertion connection between the inserts 6 and the column hole 38 further enhances the stability of the device, ensures that the protective cover 21 is installed in the correct position, reduces wear on the sealing mechanism caused by torsion, and extends the service life of the sealing structure. As a further implementation of this solution, the inner side of the expansion plate 23 is provided with a pressure groove 24. The expansion plate 23 presses the ring seat 12 through the pressure groove 24. The water collection groove 22 of the protective cover 21 contains a stacked filter element 11. The water collection groove 22 of the protective cover 21 is in contact with the top of the stacked filter element 11. Through the above settings, this pressing design not only enhances the overall stability of the device, but also ensures the stable connection of the stacked filter element 11 inside the water collection groove 22 through the pressing of the ring seat 12 by the pressure groove 24, thereby improving the reliability of the device. At the same time, by pressing the ring seat 12, the bottom end of the stacked filter element 11 is tightly attached to the second rubber sealing ring 35. As a further implementation of this solution, a slot 36 is provided on the inner side of the filter housing 31, and an insert plate 51 is inserted into the slot 36. A permanent magnet block 53 is fixedly connected to the inner side of the insert plate 51. The permanent magnet block 53 is magnetically attracted to the filter housing 31. An anti-detachment groove 52 is provided on the inner side of the insert plate 51. The anti-detachment groove 52 is sleeved on the outer side of the expansion plate 23 and is attached to the upper end of the expansion plate 23. Through the above settings, the magnetic attraction design not only enhances the overall stability of the device, but also ensures the stable connection of the insert plate 51 in the slot 36 through the magnetic attraction between the permanent magnet block 53 and the filter housing 31, preventing the insert plate 51 from detaching due to vibration. At the same time, the insertion plate 51 limits the expansion plate 23, preventing the protective cover 21 from moving away from the filter housing 31 and providing convenience for later disassembly. As a further implementation of this solution, the inner side of the annular sliding vane 42 is slidably connected to the outer side of the filter shell 31, and the column 43 can be inserted into the inner side of the insert 6. The column 43 is sealed to the inner side of the insert 6 by the third rubber sealing ring 44. Through the above-mentioned arrangement, this sliding connection and sealing design not only enhances the overall stability of the device, but also ensures good sealing performance through the insertion connection between the column 43 and the insert 6 and the sealing effect of the third rubber sealing ring 44. This reduces the wear caused by torsion on the sealing mechanism, extends the service life of the sealing structure, and improves the reliability of the device.
[0018] Workflow: During installation, the front and rear ends of the filter housing 31 are fixed and sealed to the corresponding fluid pipes. The disc filter element 11 is inserted into the assembly port 32, while the positioning plate 13 is aligned with the guide groove 34 until the ring seat 12 approaches the filter housing 31. Then, the water collection groove 22 of the protective cover 21 is fitted onto the outside of the disc filter element 11. When the protective cover 21 is about to contact the filter housing 31, the insert 6 is aligned with the column hole 38 and inserted into the column hole 38. The outer dimensions of the insert 6 are consistent with those of the column hole 38. The opening size of 8 matches, serving as a guide for the position of the protective cover 21. While keeping the protective cover 21 pressed downwards, the other hand pushes the annular slide 42 upwards. The annular slide 42 compresses the spring 41, and slides on the outside of the filter housing 31. The annular slide 42 will drive the column cylinder 43 and duckbill valve 45 upwards. At this time, the column cylinder 43 will insert into the interior of the insert 6, and the third rubber sealing ring 44 will fit against the inner side of the insert 6. When the column cylinder 43 moves upwards, the gas inside the insert 6 will pass through... The gas flows out from inside the cylinder 43 and through the duckbill valve 45. The duckbill valve 45 limits the gas flow. When the top of the cylinder 43 is in contact with the bottom of the expansion plate 23, the annular slide 42 is released. The spring force of the spring 41 pushes the annular slide 42 and the cylinder 43 back to their original positions. Due to the restriction of the gas flow by the duckbill valve 45, the cylinder 43 will cause the insert 6 and the housing assembly 2 to move downwards as a whole. At this time, the ring seat 12 can be squeezed by the pressure groove 24, so that the bottom of the protective cover 21 is tightly in contact with the second rubber sealing ring 35. When the bottom end of the expansion plate 23 is tightly attached to the first rubber sealing ring 33, a sealing effect is achieved. Then, the insert plate 51 is inserted into the inside of the slot 36. The magnetic attraction between the permanent magnet block 53 and the filter shell 31 can resist a pulling force of 10N, while preventing the insertion plate 51 from detaching from the inside of the slot 36 due to vibration. The insertion plate 51 is sleeved on the outside of the expansion plate 23 through the anti-detachment groove 52, which can prevent the protective cover 21 from detaching from the filter shell 31 due to the pressure of the fluid after the water collection tank 22 enters, thus completing the installation. In use, fluid is introduced into the front channel of the filter housing 31 and enters the assembly port 32 and the water collection tank 22. Due to the sealing of the second rubber sealing ring 35, fluid can be prevented from directly entering the middle channel from between the stacked filter element 11 and the filter housing 31. Impurities are filtered through the stacked filter element 11, and the filtered fluid enters the middle flow channel through the inside of the stacked filter element 11 and then flows out. During disassembly, the two insert plates 51 are pulled directly out of the slot 36. The port of the duckbill valve 45 is pressed with both hands to open the port of the duckbill valve 45, allowing external air to enter the column cylinder 43 and the insert cylinder 6 through the duckbill valve 45. At this time, the spring 41 pushes the annular slide plate 42 downward to slide the column cylinder 43 away from the insert cylinder 6. The protective cover 21 can then be pulled directly out from the outside of the stacked filter element 11. The stacked filter element 11 is then pulled out from the assembly port 32. This disassembly method changes the traditional spiral installation method, which is not only convenient but also ensures sealing performance. It significantly reduces the wear caused by twisting the stacked filter element 11 and the corresponding sealing mechanism of the protective cover 21, improves the life of the sealing structure, and reduces maintenance costs and equipment downtime.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
