Abstract
Description
Technical Field
[0001] This application relates to the field of municipal water supply and drainage technology, for example, to a filtration device for municipal water supply and drainage. Background Technology
[0002] Municipal water supply and drainage systems are an important part of urban infrastructure, mainly used to ensure the safety of water supply for urban residents and smooth drainage. They include water supply systems, which are responsible for delivering tap water from water sources (such as water plants) to water points for residents and businesses; drainage systems, which are responsible for collecting urban sewage and rainwater and discharging them into treatment facilities or water bodies; and filtration devices need to be installed in municipal water supply and drainage systems to remove impurities and pollutants from the water in order to improve the safety and availability of the water.
[0003] In the process of implementing the embodiments of this disclosure, it was found that at least the following problems exist in the related technology: In traditional filter devices, the filter core is mostly installed in the filter outer cylinder. After long-term use, the filter core in the filter device needs to be inspected and replaced. During the inspection and replacement, it is often necessary to disassemble the entire filter device from the municipal water supply and drainage pipeline, inspect and replace the filter core, and then reinstall the entire filter device on the municipal water supply and drainage pipeline, which makes the inspection and replacement of the filter core quite troublesome. Therefore, we propose a filter device for municipal water supply and drainage to solve the above problems. Utility Model Content

[0029] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.
[0030] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0031] Combination Figure 1-4As shown, this embodiment of the present disclosure provides a municipal water supply and drainage filtration device, including a mounting base 1, with fixing bolts 11 threadedly installed at the four corners of the mounting base 1, a water supply and drainage pipe 2 provided at the top of the mounting base 1, a filtration mechanism 3 for water filtration provided on the water supply and drainage pipe 2, and a positioning mechanism 4 provided on the water supply and drainage pipe 2 and the filtration mechanism 3.
[0032] The filter mechanism 3 includes two liquid control valves 31, both of which are installed on the water supply and drainage pipes 2 via flanges. A filter element 32 is provided between the two liquid control valves 31. The filter element 32 includes a first connecting pipe 321 and a second connecting pipe 322. The first connecting pipe 321 and the second connecting pipe 322 are respectively installed on the corresponding liquid control valves 31 via flanges. A filter core 323 is provided between the first connecting pipe 321 and the second connecting pipe 322. The bottom of the opposite ends of the first connecting pipe 321 and the second connecting pipe 322 are integrally formed with positioning protrusions 3211. The bottom of both ends of the filter core 323 are provided with positioning slots 3231 corresponding to the positioning protrusions 3211. The positioning protrusions 3211 are movably engaged in the corresponding positioning slots 3231 for positioning and installation of the filter core 323.
[0033] A limiting ring 324 is fixedly installed at one end of the first connecting pipe 321 near the filter inner core 323. An inner threaded cylinder 325 is movably sleeved on the outer side of the limiting ring 324. A first sealing ring 326 is provided between the inner wall of the inner threaded cylinder 325 and the limiting ring 324. An outer threaded frame 327 that mates with the inner threaded cylinder 325 is fixedly installed at one end of the second connecting pipe 322 near the filter inner core 323. The inner threaded cylinder 325 is threaded onto the outer side of the outer threaded frame 327. A positioning ring 3271 is integrally formed at the end of the outer threaded frame 327 away from the filter inner core 323. A second sealing ring 328 is provided between the end of the inner threaded cylinder 325 and the positioning ring 3271. The sealing installation between the first connecting pipe 321, the second connecting pipe 322, and the outer screw frame 327 ensures the sealing installation of the filter inner core 323, preventing water leakage and allowing for effective filtration. After a period of filtration, the filter inner core 323 needs to be disassembled for maintenance and replacement. In this case, simply reverse the screw rotation of the inner screw cylinder 325 to detach it from the outer screw frame 327. Then, slide the inner screw cylinder 325 to a position away from the outer screw frame 327, detaching it from the filter inner core 323. The filter inner core 323 can then be directly disassembled for maintenance and replacement without disassembling the entire filter mechanism 3.
[0034] The inner screw barrel 325 has a screw groove 3251 on the side near the outer screw frame 327, which makes it convenient to use an external tool to insert into the screw groove 3251 to screw and rotate the inner screw barrel 325.
[0035] Optionally, the positioning mechanism 4 includes two first bottom clamping frames 41, and a second bottom clamping frame 42 is provided between the two first bottom clamping frames 41. The bottom ends of the first bottom clamping frames 41 and the second bottom clamping frames 42 are integrally formed with mounting seats 43. The mounting seats 43 are fixedly installed on the mounting base 1 by bolts. The top ends of the first bottom clamping frames 41 are fixedly installed on the first top clamping frame 411 by bolts, and the top ends of the second bottom clamping frames 42 are fixedly installed on the second top clamping frame 421 by bolts. The water supply and drainage pipe 2 is movably clamped between the corresponding two sets of first bottom clamping frames 41 and first top clamping frames 411 for positioning and installation of the water supply and drainage pipe 2.
[0036] Optionally, the first connecting pipe 321 is movably snapped between a corresponding set of second bottom frames 42 and second top frames 421; the second connecting pipe 322 is movably snapped between a corresponding set of second bottom frames 42 and second top frames 421 for positioning and installation of the filter mechanism 3, which increases the accuracy of the filter mechanism 3 installation, thereby improving the stability of the filter mechanism 3 installation and facilitating the disassembly of the entire filter mechanism 3.
[0037] Working principle: When in use, the water supply and drainage pipe 2 is movably connected between the corresponding two sets of first bottom clamp frames 41 and first top clamp frames 411 to position and install the water supply and drainage pipe 2.
[0038] Subsequently, the filter mechanism 3 can be movably connected between the corresponding set of second bottom frames 42 and second top frames 421 via the first connecting pipe 321, and the second connecting pipe 322 can be movably connected between the corresponding set of second bottom frames 42 and second top frames 421 to position and install the filter mechanism 3, thereby increasing the accuracy of the filter mechanism 3 installation and improving the stability of the filter mechanism 3 installation.
[0039] Water is effectively filtered through the filter core 323. After a period of filtration, the filter core 323 needs to be disassembled for maintenance and replacement. At this time, simply turn the inner screw cylinder 325 in the reverse direction to detach the inner screw cylinder 325 from the outer screw frame 327. Then, slide the inner screw cylinder 325 to a position away from the outer screw frame 327 to detach the inner screw cylinder 325 from the filter core 323. Then, the filter core 323 can be directly disassembled for maintenance and replacement without disassembling the entire filter mechanism 3, which is simple and convenient.
