Technical Field

[0001] The utility model relates to the technical field of urban water supply, in particular to a filter for an urban water supply network. Background Art

[0002] A filter for an urban water supply network is a device used in an urban water supply system, mainly for removing suspended impurities, particulate matters, sediment, algae, microorganisms, etc. in water to ensure that the water quality delivered to the user terminal meets the drinking or usage standards.

[0003] Chinese Patent Publication No. CN219879295U, published on October 24, 2023, discloses a filter for an urban water supply network, including a water pipe. An inlet pipe is arranged on one side of the water pipe. Two filter components are oppositely arranged on both sides of the water pipe. The filter component includes an installation shell and a filter element arranged in the installation shell. The installation shell is communicated with the water pipe. A regulating valve is arranged on the water pipe. The regulating valve is used to control the water flow to one of the installation shells. An outlet pipe is arranged on one side of the installation shell.

[0004] For an existing filter for an urban water supply network such as the above, rotate the regulating valve to control the water flow into one of the installation shells. At this time, the filter element in the other installation shell can be replaced or cleaned. By rotating the bolt to disengage the two threaded sleeves and then opening the cover plate, the filter element can be taken out. In the specific implementation process, due to the need to consider the deflection path, the flip-type cover plate often cannot well ensure the airtightness between the cover plate and the installation shell bracket. Therefore, it is urgent to propose a corresponding filter for an urban water supply network to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a filter for an urban water supply network to solve the above problems.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A filter for an urban water supply network includes a first filter cartridge 1, a first three-way pipe 2 and a second three-way pipe 3, a second filter cartridge 4 and a top cover 10. Filter elements 5 are fixedly connected to the inner surfaces of both the first filter cartridge 1 and the second filter cartridge 4. A bracket 6 and a connecting frame 7 are fixedly connected between the first filter cartridge 1 and the second filter cartridge 4. The first three-way pipe 2 includes a water inlet pipe 201, a port one 202 and a port two 203. The second three-way pipe 3 includes a water outlet pipe 301, a port three 302 and a port four 303. The port one 202 and the port three 302 are both connected to the second filter cartridge 4 for transmission. The port two 203 and the port four 303 are both connected to the first filter cartridge 1 for transmission. Convex rings 15 are fixedly connected to the bottoms of the two top covers 10, and sealing gaskets 16 are fixedly connected to the bottoms of the convex rings 15. And a limiting component for vertically limiting the top cover 10 is provided at the top of the connecting frame 7;

[0025] In the initial stage, port 1 (202) and port 3 (302) are opened. The water body is transferred from the water inlet pipe through port 1 (202) to filter cartridge 2 (4). After being filtered by the filter element 5 inside filter cartridge 2 (4), it is discharged through port 3 (302) and the water outlet 301. Subsequently, three-way pipe 1 (2) and three-way pipe 2 (3) are respectively turned to port 2 (203) and port 4 (303). The water body introduced by the water inlet pipe 201 will then enter filter cartridge 1 (1), and filter cartridge 1 (1) will continue to filter the water body. After that, the locking rod 11 between the rotatable deflection lever 9 and the top cover 10 can be rotated. Then, the deflection lever 9 is turned to one side. At this time, the top cover 10 can be pulled out upward, and the filter element 5 can be quickly separated from filter cartridge 2 (4). By repeating this process, on the basis of realizing continuous filtration of the filter, the airtightness between the top cover 10 and filter cartridge 4 is ensured through the vertical upward separation method of the top cover 10 in combination with the convex ring 15 and the sealing gasket 16;

[0026] It should be noted that: both three-way pipe 1 (2) and three-way pipe 2 (3) are prior arts, so the switching of port opening and closing will not be elaborated here.

[0027] Specifically, as Figure 2 shown in Figure 4 , both the bottom of filter cartridge 1 (1) and filter cartridge 2 (4) are fixedly connected with T-shaped pipes. The horizontal ends of the two T-shaped pipes are respectively fixedly connected with port 3 (302) and port 4 (303), and valves are integrated at the bottoms of the vertical ends of the two T-shaped pipes. The bottoms of filter cartridge 1 (1) and filter cartridge 2 (4) are both fixedly connected with T-shaped pipes, and valves are integrated at the bottoms of the vertical ends of the two T-shaped pipes. Taking filter cartridge 2 (4) as an example, after transferring the water body to filter cartridge 1 (1) and taking out the filter element 5, if the inside of filter cartridge 2 (4) needs to be cleaned, the valve on the T-shaped pipe at the bottom of filter cartridge 2 (4) can be opened. The mixed turbid liquid generated after cleaning the inside of filter cartridge 2 (4) with external cleaning agent and water can be directly discharged through the vertical end of the T-shaped pipe, thus ensuring the convenience of subsequent maintenance of the filter for urban water supply networks.

[0028] Specifically, as Figure 2 shown in Figure 3As shown in the figure, the limit component includes a top frame 8 fixedly connected to the top of the connecting frame 7. The top of the top frame 8 is rotatably connected to a deflection lever 9. The deflection lever 9 is screwed to the top of the top cover 10 through a locking rod 11. The deflection lever 9 is placed on the top of the top cover 10, and the deflection lever 9 and the top cover 10 are screwed simultaneously through the locking rod 11 to realize the limit of the top cover 10. An interference fit is provided between the inner surface of the top of the deflection lever 9 and a rubber plug 12. The bottom of the rubber plug 12 abuts against the top of the locking rod 11. The interference fit ensures the stability of the position of the rubber plug 12 itself. The rubber plug 12 isolates the locking rod 11. A vertical rod is fixedly connected to the inner surface of the top of the top cover 10, and the bottom of the vertical rod abuts against the top of the filter element 5 to reinforce the filter element 5. L-shaped insertion frames 13 are fixedly connected to the outer surfaces of both the first filter cylinder 1 and the second filter cylinder 4. The outer surfaces of the vertical ends of the two top frames 8 are fixedly connected with clamping sleeves 14 combined with the insertion frames 13. This can realize the rapid positioning of the top cover 10 while restricting the axial deflection of the top cover 10.

[0029] Working principle: In the initial stage, port one 202 and port three 302 are opened. The water body is transferred from the water inlet pipe to port one 202 and then to the second filter cylinder 4. After being filtered by the filter element 5 inside the second filter cylinder 4, it is exported through port three 302 and the water outlet 301. Subsequently, the first three-way pipe 2 and the second three-way pipe 3 are respectively toggled to port two 203 and port four 303. The water body introduced by the water inlet pipe 201 will enter the first filter cylinder 1, and the first filter cylinder 1 will continue to filter the water body. After that, the locking rod 11 between the deflection lever 9 and the top cover 10 can be rotated, and then the deflection lever 9 is toggled to one side. At this time, the top cover 10 can be pulled out upward, and the filter element 5 can be quickly separated from the second filter cylinder 4. By repeating this process, on the basis of realizing continuous filtration of the filter, the airtightness between the top cover 10 and the filter cylinder 4 is ensured through the upward separation method of the top cover 10 in combination with the convex ring 15 and the sealing gasket 16. The bottoms of both the first filter cylinder 1 and the second filter cylinder 4 are fixedly connected with T-shaped pipes, and valves are integrated at the bottoms of the vertical ends of the two T-shaped pipes. Taking the second filter cylinder 4 as an example, after the water body is transferred to the first filter cylinder 1 and the filter element 5 is taken out, if the inside of the second filter cylinder 4 needs to be cleaned, the valve on the T-shaped pipe at the bottom of the second filter cylinder 4 can be opened. The mixed turbid liquid generated after cleaning the inside of the second filter cylinder 4 with external cleaning agent and water can be directly exported through the vertical end of the T-shaped pipe, which ensures the convenience of subsequent maintenance of the filter for urban water supply networks.
