Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage, in particular to a municipal water supply and drainage filtering device. Background Art

[0002] Municipal water supply and drainage mainly provides users with clean domestic water through pipelines. Water needs to be transported from the water plant to users through various pipelines. Due to the difficulty of cleaning the pipelines and the aging of the pipelines, a large amount of impurities will accumulate in the pipelines. After being transported to users, the water will be mixed with certain impurities and harmful substances, which greatly reduces the quality of the water.

[0003] However, after the existing municipal water supply and drainage filtering devices have been running for a period of time, the filter residues can easily cause blockage inside the filtering device, resulting in poor water flow and reduced filtering efficiency. In addition, the water valve needs to be closed during cleaning, and water cannot be used any further, which is quite troublesome. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-4 As shown, the municipal water supply and drainage filtering device comprises an inlet pipe 1, one side of the inlet pipe 1 is fixedly connected with a shunt pipe 2, the other two ends of the shunt pipe 2 are respectively fixedly connected with a branch pipe 1 3 and a branch pipe 2 4, one side of the branch pipe 1 3 is fixedly connected with an outlet pipe 6, a connecting pipe 5 is fixedly connected between the branch pipe 2 4 and the outlet pipe 6, and a filtering structure 7 is arranged between the shunt pipe 2, the branch pipe 1 3 and the outlet pipe 6;

[0025] The filtering structure 7 includes a base 701, which is connected to the bottom end of the branch pipe 3 by a plurality of bolts, a filter cartridge 702 is fixedly connected to the top of the base 701, a valve 703 is fixedly installed at the position of the branch pipe 3 close to the diversion pipe 2, a valve 2 704 is fixedly installed at the position of the outlet pipe 6 close to the branch pipe 3, and a filter screen 705 is fixedly installed in the diversion pipe 2 close to the position of the branch pipe 24.

[0026] In this embodiment, the filter cartridge 702 is in close contact with the inner wall of the branch pipe 3 , and the top of the filter cartridge 702 is higher than the top of the connection between the branch pipe 3 and the water outlet pipe 6 .

[0027] The filter cartridge 702 plays a filtering role to prevent impurities from being stuck between the filter cartridge 702 and the branch pipe 3. The height of the filter cartridge 702 allows water to pass through the filter cartridge 702 and then enter the water outlet pipe 6, achieving a good filtering effect.

[0028] In this embodiment, the diverter pipe 2 is a “Y”-shaped structure, and the filter screen 705 is flush with the inner wall of the diverter pipe 2 .

[0029] The diverter pipe 2 plays a role of diversion, and the filter screen 705 plays a role of filtering. The "Y"-shaped structure makes the two sides of the diverter pipe 2 an inclined structure, so that the filter screen 705 is in an inclined state, thereby preventing impurities from remaining on the surface of the filter screen 705.

[0030] In this embodiment, the filter cartridge 702 has an open top, and the pore size of the filter cartridge 702 is consistent with that of the filter screen 705 .

[0031] The top end of the filter cartridge 702 is open, so that impurities are collected inside the filter cartridge 702 when filtered by the filter cartridge 702 , and the filtering effects of the filter cartridge 702 and the filter screen 705 are consistent.

[0032] In this embodiment, an anti-blocking structure 8 is provided in the branch pipe 2 4, and the anti-blocking structure 8 includes a blocking plate 801, and the blocking plate 801 is fixedly connected to one side of the branch pipe 2 4, and a plurality of filtering holes 802 are provided at the connection between the branch pipe 2 4 and the connecting pipe 5, and an adjusting plate 804 is slidably installed inside the branch pipe 2 4, and a spring 803 is fixedly connected between the adjusting plate 804 and the blocking plate 801.

[0033] The anti-blocking structure 8 ensures that when the filter cartridge 702 is blocked, the water flow will flow through the branch pipe 2 4 and the connecting pipe 5 under the action of water pressure and enter the water outlet pipe 6 to be output, thereby regulating the water flow and cleaning the filter cartridge 702 while still being able to transport tap water.

[0034] In this embodiment, the adjustment plate 804 is a cylindrical structure and is in close contact with the inner wall of the branch pipe 2 4 .

[0035] The regulating plate 804 plays a blocking role to prevent water from flowing out of the branch pipe 2 4 . The close contact between the regulating plate 804 and the branch pipe 2 4 makes the movement of the regulating plate 804 more stable.

[0036] In this embodiment, the pore sizes of the filter holes 802 are uniform, and the filter holes 802 are evenly distributed at the connection between the branch pipe 2 4 and the connecting pipe 5 .

[0037] The filter holes 802 support the adjustment plate 804, thereby preventing the adjustment plate 804 from moving unstably when passing through the connecting pipe 5. The consistent aperture of the filter holes 802 makes the water flow more stable when passing through.

[0038] It should be noted that the utility model is a municipal water supply and drainage filtering device. When in use, water flows through the water inlet pipe 1. When passing through the diversion pipe 2, the water flow is difficult to pass due to the anti-blocking structure 8 of the branch pipe 2 4. The water flow will be filtered by the filter cartridge 702 along the branch pipe 1 3 and then enter the water outlet pipe 6 for delivery;

[0039] When water flows through the filter cartridge 702, impurities are filtered and collected by the filter cartridge 702. When there are too many impurities and blockage occurs, the water flows through the filter screen 705 and enters the branch pipe 4 under the action of water pressure, thereby squeezing the spring 803 on the blocking plate 801, so that the regulating plate 804 moves along the branch pipe 4, so that the water flows through the filter hole 802 and enters the connecting pipe 5 and the water outlet pipe 6 to be transported, so that the transported water flow is relatively constant.

[0040] When the filter cartridge 702 is blocked, the water flow in the branch pipe 3 is cut off by closing valve 1 703 and valve 2 704, and the water flow is transported through branch pipe 2 4, anti-blocking structure 8 and connecting pipe 5. By releasing the bolts, the base 701 can drive the filter cartridge 702 to separate from the branch pipe 3, so that it can be cleaned more conveniently and quickly.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
