[0002] Municipal water supply and drainage filtration devices are used to remove various sludge or impurities in life and production, thereby avoiding blockage inside the pipes. This not only ensures smooth water flow, but also provides clean and safe water resources for urban residents and various production activities.

[0003] The filtering effect of existing filtering devices needs to be improved. Many impurities will enter the pipe with the water flow. Over time, these impurities will settle inside the pipe and gradually form blockages. Especially in areas where impurities are easily accumulated, such as pipe bends and joints, the risk of blockage is higher. And it affects the flow rate of water during filtration. The reduction of water flow rate not only affects the normal operation of the water supply and drainage system, but also increases the energy consumption and maintenance cost of the water pump.

[0004] Therefore, the utility model proposes a new filtering device for municipal water supply and drainage. Utility Model Content

[0049] The present invention will be further described below in conjunction with the embodiments.

[0050] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0051] like Figures 1 to 3 , Figure 5 As shown, the municipal water supply and drainage filtering device comprises a filtering body 6, wherein the filtering body 6 comprises a first butt joint fitting 2 connected to a first pipe 1, a first connecting pipe 4 butt jointed with the first butt joint fitting 2, a filtering box, a second butt joint fitting connected to a second pipe 10, and a second connecting pipe 12 butt jointed with the second butt joint fitting;

[0052] The filter body 6 is provided with a filter chamber 11, a plurality of spiral blades (5, 20) and a sewage discharge pipe, wherein the height of the filter chamber 11 is greater than or equal to the height of the second connecting pipe 12; the plurality of rotating blades 5 are arranged along the axial direction of the long axis 3 to form a continuous but not completely closed channel;

[0053] The sewage pipe includes a first sewage pipe 8 and a second sewage pipe 7. The surface of the first sewage pipe 8 is provided with a plurality of through holes, and the height of the through holes is less than or equal to the height of the filter chamber 11. The second sewage pipe 7 is connected to the first sewage pipe 8 through an angle pipe fitting, and one end of the second sewage pipe is exposed from the filter body 6 to discharge sludge or impurities.

[0054] In this embodiment, the working process of the municipal water supply and drainage filtering device is as follows:

[0055] The water flows into the spiral blades (5, 20) through the first pipe 1. The spiral blades (5, 20) are arranged along the axial direction of the long axis 3 to form a continuous but not completely closed channel. After the water flows and drives the spiral blades (5, 20), the rotation of the spiral blades (5, 20) accelerates the flow rate of the water flow, and the impurities are pushed to the edge of the blades, so that the sludge and impurities are better separated and gradually move to the filter box cavity with the rotation. Since the height of the filter chamber 11 is greater than or equal to the height of the second connecting pipe 12, it is ensured that the water flow can fully flow through the filter box cavity (composed of the first outer surface 15 of the filter chamber, the upper surface 13 of the filter chamber, the second outer surface 17 of the filter chamber, and the bottom surface 18 of the filter chamber). The separated sludge and impurities are fully stirred in the filter chamber 11 and continuously enter the first sewage pipe 8 through the multiple through holes of the first sewage pipe 8. Then, they enter the second sewage pipe 7 through the angle pipe fitting and are finally discharged from the filter body 6. The filtered water flows into the second pipe 10 through the second connecting pipe 12. In this process, the water flow has removed most of the sludge and impurities, ensuring the quality of the effluent. Finally, the clean water flow continues to flow to the next treatment unit or directly discharges into the water body through the second butt joint fitting and the second pipe 10.

[0056] Specifically, the filter body 6 is constructed using corrosion-resistant metal materials (such as stainless steel) or polymer materials (such as polyethylene). The design of the butt joint fittings should ensure compatibility with standard pipe sizes and facilitate installation and disassembly. A filter chamber 11 is installed in the center or appropriate position of the filter body 6, and the height of the filter chamber 11 should be greater than or equal to the height of the second connecting pipe 12. Multiple spiral blades (5, 20) are arranged axially along the major axis 3 to form a continuous but not completely closed channel. A plurality of through holes are provided on the surface of the first sewage pipe 8 to allow sludge and impurities to enter the pipe. The height of the first sewage pipe 8 should be less than or equal to the height of the filter chamber 11 to ensure that it can effectively collect and remove trapped impurities. The second sewage pipe 7 is connected to the first sewage pipe 8 through an angled pipe fitting. The design of the angled pipe fitting should ensure that the water flow can smoothly turn from the first sewage pipe 8 to the second sewage pipe 7. One end of the second sewage pipe 7 exposes the filter body 6 to facilitate the discharge of sludge and impurities. The installation process is similar to the installed device as shown in the figure. Figure 6 , Figure 7 shown.

[0057] Optionally, one end of the first sewage pipe 8 is arranged on the bottom surface 18 of the filter chamber 11 through a first bearing 9, and the other end is connected to the angle pipe fitting through a second bearing. The first bearing 9 and the second bearing are respectively arranged in a closed shell.

[0058] The first sewage pipe 8 is mounted on the bottom surface 18 of the filter chamber 11 through the first bearing 9, ensuring that the pipe is not easy to move or shake during operation, thereby ensuring the stability of the entire sewage system. The bearing makes the first sewage pipe 8 rotate more smoothly, speeds up the rotation speed, and facilitates the removal of sludge or impurities.

[0059] Optionally, one end of the long shaft 3 is disposed on the first butt joint member 2 via a third bearing, and the other end is disposed on the second butt joint member via a fourth bearing.

[0060] One end of the long shaft 3 is inserted into the third bearing and fixed in the first butt joint member 2, and the other end is inserted into the fourth bearing and fixed in the second butt joint member 2. The long shaft 3 is supported by the two butt joint members and realizes the rotation function through the bearings.

[0061] Optionally, a motor is provided on the outer side of one end of the first sewage pipe 8 disposed on the bottom surface 18 of the filter chamber 11, and the first sewage pipe 8 is driven to rotate by the motor.

[0062] The driving motor is connected to the first sewage pipe 8 through a transmission mechanism, which may include gears, belts or couplings, etc., and its function is to transmit the rotational power of the motor to the first sewage pipe 8. The first sewage pipe 8 is driven to rotate by the motor, which improves the sewage discharge efficiency, helps to quickly remove the dirt in the filter chamber 11, and prevents blockage and accumulation.

[0063] Optionally, the inner surface of the filter cavity 11 is provided with a plurality of through holes.

[0064] Multiple through holes are evenly distributed on the inner surface of the filter cavity 11, which may be circular, square or other shapes. The layout of the through holes should ensure that the liquid or solid particles in the filter cavity 11 can pass through these holes evenly, thereby achieving effective filtration and sewage discharge.

[0065] Optionally, the third bearing and the fourth bearing are respectively arranged in a closed shell.

[0066] In order to ensure that the bearing works normally in the closed housing and prevent contaminants from entering, seals, O-rings, etc. are used to ensure the cleanliness and lubrication of the bearing.

[0067] Optionally, the intervals between the plurality of rotating blades 5 increase sequentially along the axial direction of the major axis 3 .

[0068] As the intervals between the rotating blades 5 gradually increase, the resistance encountered by the fluid when passing through will gradually decrease, thereby increasing the flow rate of the liquid.

[0069] Optionally, a plurality of filter chamber support frames 14 are disposed on the upper surface 13 of the filter chamber 11 , and the second connecting pipe 12 is connected via the filter chamber support frames 14 .

[0070] The support frame is fixed to the upper surface 13 of the filter chamber 11 by welding, screwing or other connection methods, and bears the weight of the second connecting pipe 12 and the vibration generated during operation. One end of the second connecting pipe 12 is connected to the upper surface 13 of the filter chamber 11 by an appropriate connection method (such as flange connection, clamp connection, etc.).

[0071] Optionally, a portion of the surface of the second connecting pipe 12 disposed in the filter cavity 11 is provided with a plurality of through holes.

[0072] Part of the surface of the second connecting pipe 12 has a plurality of through holes, which may be circular or in other shapes, to ensure that the fluid is evenly distributed inside the pipe and reduce uneven flow velocity or the formation of vortices.

[0073] In summary, the utility model includes a filter body, the filter body includes a first butt joint pipe connected to a first pipe, a first connecting pipe butt jointed to the first butt joint pipe, a filter box, a second butt joint pipe connected to a second pipe, and a second connecting pipe butt jointed to the second butt joint pipe; a filter cavity, a plurality of spiral blades (5, 20) and a sewage pipe are arranged in the filter body, the height of the filter cavity is greater than or equal to the height of the second connecting pipe; the plurality of rotating blades are arranged along the axial direction of the long axis to form a continuous but not completely closed channel; the sewage pipe includes a first sewage pipe and a second sewage pipe, the surface of the first sewage pipe is provided with a plurality of through holes, the height of which is less than or equal to the height of the filter cavity, and the second sewage pipe is connected to the first sewage pipe through an angle pipe, one end of which is exposed from the filter body to discharge sludge or impurities. The municipal water supply and drainage filter device provided by the utility model forms a water flow vortex by setting a filter cavity and a plurality of spiral blades (5, 20), which can effectively accumulate and remove sludge and impurities in the water flow. Since the spiral blades (5, 20) form a continuous but not completely closed channel, the water flow is increased, the filtering efficiency is improved, and the risk of blockage is reduced. The height of the filter chamber is greater than or equal to the height of the second connecting pipe to prevent impurities from accumulating and causing blockage during the filtering process. By setting the first sewage pipe and the second sewage pipe, the sludge and impurities trapped during the filtering process can be easily discharged. The multiple through holes on the surface of the first sewage pipe allow impurities to enter the pipe, while the second sewage pipe is connected to the first sewage pipe through an angle pipe fitting to discharge the impurities from the filter body. By setting a motor to drive the first sewage pipe to rotate, the power transmission during the filtering process is enhanced, and the filtering efficiency and sewage discharge effect are improved.
