[0034] Water hammer phenomenon exists during pipeline transportation. Water hammer, also known as water shock, is a phenomenon in which a water body flowing in a pressure pipeline suddenly changes due to some external factors (such as sudden valve closure, sudden pump stop, etc.), resulting in a sharp change in flow velocity, and then causing a large fluctuation in pressure. Sometimes, this pressure fluctuation can generate a large pressure peak in the pipeline, and its value may far exceed the normal working pressure in the pipeline, thus causing great damage to the pipeline system. Specifically, when the valve suddenly closes or the pump suddenly stops, the water body that was flowing smoothly in the pipeline loses its forward driving force, quickly decelerates and accumulates near the valve or pump body, forming a high-pressure area. This high-pressure area will spread towards both ends of the pipeline, forming a pressure wave. When this pressure wave encounters structures such as elbows and tees in the pipeline, reflection and superposition will also occur, further enhancing the pressure peak in the pipeline.

[0035] In order to reduce the maintenance frequency of water-using equipment and underground pipe networks and contribute to the normal operation of cigarette production, this embodiment provides an underground pipe network drainage and filtration device. The following will be combined with Figures 1 to 2 to describe the specific content of this embodiment in detail. It should be noted that the first direction mentioned in this embodiment is the Figure 1 Y direction in Figure 1 and the second direction mentioned in this embodiment is the

[0036] X direction in Figure 1 As shown in

[0037] the underground pipe network drainage and filtration device in this embodiment includes a filtration container, a filter screen 4, a water hammer eliminator 9, a first pipeline 6, a second pipeline 7, and a third pipeline 8. The filtration container includes a cylindrical tank body 1 with a hollow interior, a first closing cover 2, and a second closing cover 3. The cylindrical tank body 1 is arranged along the first direction, and the first closing cover 2 and the second closing cover 3 are respectively and hermetically connected to both ends of the cylindrical tank body 1 along the first direction. The filter screen 4 is arranged inside the filtration container along the first direction and divides the filtration container into a first accommodation cavity 101 and a second accommodation cavity 102 along the second direction. The first direction is perpendicular to the second direction. The water hammer eliminator 9 is arranged on the first closing cover 2 and communicates with the first accommodation cavity 101. Water first enters the first accommodation cavity 101 through the first pipeline 6. By adding a water hammer eliminator 9 communicating with the first accommodation cavity 101, the intensity of the water hammer from the pipeline can be greatly reduced, and the service life of the filtration container can be greatly extended. The first pipeline 6 is connected to the cylindrical tank body 1 and communicates with the first accommodation cavity 101. The second pipeline 7 is connected to the cylindrical tank body 1 and communicates with the second accommodation cavity 102. The third pipeline 8 is connected to the second closing cover 3 and is connected to the first accommodation cavity 101.

[0037] The underground pipe network drainage filtering device provided in this embodiment seals and connects the first closing cover 2 and the second closing cover 3 at both ends of the cylindrical tank body 1 to enclose a sealed cavity. The cylindrical tank body 1 is vertically placed in the first direction. The filter screen 4 is installed in the filtering container, and the cavity of the filtering container is divided into a first accommodating cavity 101 and a second accommodating cavity 102. The water hammer eliminator 9, the first pipeline 6 and the third pipeline 8 are all communicated with the first accommodating cavity 101, and the second pipeline 7 is communicated with the second accommodating cavity 102. Water from the municipal water supply system is introduced into the filtering container through the first pipeline 6. On the one hand, since the filtering container is provided with a filter screen, it can effectively filter out particulate matter in the water, avoid pipeline blockage, and reduce the maintenance frequency of water-using equipment and the underground pipe network. On the other hand, since the water hammer eliminator 9 is provided on the filtering container, it can effectively eliminate the water hammer effect of the water flow in the pipeline, extend the service life of the filtering container, and contribute to the normal operation of cigarette production. The filter screen 4 can block solid particulate matter in the water from entering the second accommodating cavity 102, and the solid particulate matter precipitates on the second closing cover 3 and is discharged from the filtering container through the third pipeline 8 for centralized treatment. By increasing the pressure of the delivery pump to accelerate the water flow rate in the first pipeline 6, since the cylindrical tank body 1 of the filtering container is of a cylindrical structure, the stress concentration of the filtering container is greatly reduced, and the compressive capacity is improved.

[0038] Optionally, as shown in the reference Figure 2 Both the first closing cover 2 and the second closing cover 3 are of hemispherical structure. By adopting the first closing cover 2 and the second closing cover 3 of hemispherical structure, the compressive capacity of the filtering container is further improved. Exemplarily, the inner diameter of the cylindrical tank body 1 is 500 mm, and the thickness of the side wall is 5 mm; the first closing cover 2 and the second closing cover 3 have the same size, both being hollow hemispheres with an inner diameter of 500 mm and a thickness of 5 mm.

[0039] Optionally, both the first closing cover 2 and the second closing cover 3 are welded to the cylindrical tank body 1. The cylindrical tank body 1, the first closing cover 2 and the second closing cover 3 are all made of metal materials, and the welding connection method ensures the stability of the connection.

[0040] Furthermore, a plurality of water hammer eliminators 9 are spacedly arranged on the first closing cover 2. By adding a plurality of water hammer eliminators 9 according to the actual use situation, the water hammer effect can be effectively reduced.

[0041] Furthermore, the underground pipe network drainage filtering device further includes a one-way exhaust valve 10, and the one-way exhaust valve 10 is arranged on the first closed cover 2 and communicated with the second accommodating cavity 102. By adding the one-way exhaust valve 10, the non-condensable gas in the liquid can be discharged in time, reducing the occurrence of water hammer problems caused by the mixture of gas and water. By adding the water hammer eliminator 9 and the one-way exhaust valve 10, both the first accommodating cavity 101 and the second accommodating cavity 102 have the function of eliminating the water hammer effect, prolonging the service life of the underground pipe network drainage filtering device.

[0042] Optionally, a plurality of one-way exhaust valves 10 are arranged on the first closed cover 2 at intervals. The number of one-way exhaust valves 10 is designed according to the actual use situation and will not be limited too much here.

[0043] Furthermore, a first flange 61 is arranged at the pipe orifice at the end of the first pipe 6 far from the cylindrical tank 1. By adding the first flange 61, the water input pipe from the water supply system can be hermetically connected to the first pipe 6 by using fasteners such as bolts. A sealing washer is arranged between the water input pipe and the first flange 61 to ensure the connection tightness and avoid liquid leakage.

[0044] Optionally, the underground pipe network drainage filtering device further includes a pressure gauge 12, and the pressure gauge 12 is arranged on the first closed cover 2, and one end of the pressure gauge is communicated with the cylindrical tank 1. Maintenance personnel can observe the water pressure inside the filtering container in real time through the pressure gauge 12.

[0045] Furthermore, a second flange 71 is arranged at the pipe orifice at the end of the second pipe 7 far from the cylindrical tank 1. By adding the second flange 71, the liquid that has completed pretreatment in the second pipe 7 can be hermetically connected to the water output pipe in the underground water pipe network by using fasteners such as bolts. A sealing washer is arranged between the water output pipe and the second flange 71 to ensure the connection tightness and avoid liquid leakage.

[0046] Optionally, the underground pipe network drainage filtering device further includes a chemical dosing port 5, and the chemical dosing port 5 is arranged on the cylindrical tank 1 and communicated with the first accommodating cavity 101. Chemical reagents are added to the water inside the filtering container through the chemical dosing port 5, so that the substances in the water react with the chemical reagents to form flocculent precipitates. The filter screen 4 can block the flocculent precipitates in the water from entering the second accommodating cavity 102. The flocculent precipitates settle on the second closed cover 3 and are discharged from the filtering container through the third pipe 8 for centralized treatment.

[0047] Further, a stop valve 11 is provided on the third pipeline 8, and the pipe orifice at one end of the third pipeline 8 close to the second closing cover 3 is conical. The opening or closing of the third pipeline 8 can be controlled by the stop valve 11. One end pipe orifice of the third pipeline 8 is designed into a conical structure, which is convenient for the flocculent precipitate or solid particulate matter to concentrate and converge towards the third pipeline 8, and is convenient for discharging after the stop valve 11 is opened. In some application scenarios, the stop valve 11 is an electromagnetic switch valve, and the stop valve 11 is electrically connected to the controller. When flocculent precipitate or solid particulate matter is detected in the third pipeline 8, the stop valve 11 can be automatically opened.
