[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] A car dumper is a large piece of machinery used to unload bulk material from open railway cars. It flips or tilts railcars to facilitate unloading and is a key piece of equipment for port unloading operations. To meet environmental requirements, the car dumper is equipped with a long-term dust suppression system, a dry mist system, and surface sprinklers. To effectively utilize various water sources and save costs, the water for the car dumper is currently drawn primarily from a scenic lake. The lake's primary sources include rainwater collected from the maintenance base area, treated coal-containing wastewater, ship ballast water, and municipal tap water replenished during the dry season. However, during operation, it was discovered that the sprinkler solenoid valve and piping in the long-term dust suppression system were frequently clogged by live clams and clam shells, necessitating frequent disassembly of the piping and solenoid valve, severely impacting the car dumper's watering effectiveness and efficiency. Upon consultation, it was learned that the water inlet chamber is equipped with a filter, and that the clams are gradually growing in the water supply pipes. Therefore, clogged pipes and solenoid valves by clams are a pressing issue that needs to be addressed.

[0039] Example 1

[0040] like Figure 1 As shown, in order to solve the above technical problems, an embodiment of the present invention provides a pipeline filtering device, including a filter chamber 10 and a filter screen 20; the filter chamber 10 is provided with an inlet pipe 110, an outlet pipe 120 and a waste pipe 130; the filter screen 20 is arranged in the filter chamber 10, and the filter screen 20 divides the filter chamber 10 into a connected buffer zone 140 and a cleaning zone 150, the buffer zone 140 is respectively connected to the inlet pipe 110 and the waste pipe 130, and the cleaning zone 150 is connected to the outlet pipe 120; wherein, part of the cleaning zone 150 is located above the buffer zone 140, and another part of the cleaning zone 150 is located on the side of the buffer zone 140 close to the outlet pipe 120, so that the cleaning zone 150 surrounds the buffer zone 140.

[0041] As can be seen above, the filter screen 20 is provided to separate the filter chamber 10 into a buffer zone 140 and a cleaning zone 150. Water entering the water inlet pipe 110 first enters the buffer zone 140, is filtered by the filter screen 20, and then flows into the cleaning zone 150. After flowing out of the outlet pipe 120, it is supplied to various water-demanding areas. Impurities filtered out by the filter screen 20, such as clam shells and clams, are temporarily stored in the buffer zone 140. Impurities in the buffer zone 140 are discharged through the waste pipe 130, thereby solving the problem of easy clogging of the pipeline and solenoid valve, eliminating the need for frequent disassembly of the pipeline and solenoid valve, and ensuring that the dumper can spray water and suppress dust normally. In addition, by arranging part of the cleaning zone 150 above the buffer zone 140 and another part of the cleaning zone 150 on the side of the buffer zone 140 close to the outlet pipe 120, the cleaning zone 150 surrounds the buffer zone 140, increasing the volume of the buffer zone 140 and allowing it to accommodate more impurities.

[0042] It should be noted that the water inlet pipe 110 is connected to the water source of the tipper. The water source of the tipper includes but is not limited to rainwater collected in the base area, treated coal-containing sewage, ship ballast fresh water, and one or more of the municipal tap water replenished in the dry season. The water outlet pipe 120 is connected to the tipper system to supply water for the tipper's sprinkling and dust suppression.

[0043] It should also be noted that the filter screen 20 is provided with a plurality of filter holes.

[0044] Example 2

[0045] like Figure 1 As shown, the pipeline filtering device includes a filter chamber 10 and a filter screen 20; the filter chamber 10 is provided with an inlet pipe 110, an outlet pipe 120 and a waste pipe 130; the filter screen 20 is arranged in the filter chamber 10, and the filter screen 20 divides the filter chamber 10 into a connected buffer zone 140 and a cleaning zone 150, the buffer zone 140 is respectively connected to the inlet pipe 110 and the waste pipe 130, and the cleaning zone 150 is connected to the outlet pipe 120; wherein, part of the cleaning zone 150 is located above the buffer zone 140, and another part of the cleaning zone 150 is located on the side of the buffer zone 140 close to the outlet pipe 120, so that the cleaning zone 150 surrounds the buffer zone 140.

[0046] As can be seen above, the filter screen 20 is provided to separate the filter chamber 10 into a buffer zone 140 and a cleaning zone 150. Water entering the water inlet pipe 110 first enters the buffer zone 140, is filtered by the filter screen 20, and then flows into the cleaning zone 150. After flowing out of the outlet pipe 120, it is supplied to various water-demanding areas. Impurities filtered out by the filter screen 20, such as clam shells and clams, are temporarily stored in the buffer zone 140. Impurities in the buffer zone 140 are discharged through the waste pipe 130, thereby solving the problem of easy clogging of the pipeline and solenoid valve, eliminating the need for frequent disassembly of the pipeline and solenoid valve, and ensuring that the dumper can spray water and suppress dust normally. In addition, by arranging part of the cleaning zone 150 above the buffer zone 140 and another part of the cleaning zone 150 on the side of the buffer zone 140 close to the outlet pipe 120, the cleaning zone 150 surrounds the buffer zone 140, increasing the volume of the buffer zone 140 and allowing it to accommodate more impurities.

[0047] It should be noted that the water inlet pipe 110 is connected to the water source of the tipper. The water source of the tipper includes but is not limited to rainwater collected in the base area, treated coal-containing sewage, ship ballast fresh water, and one or more of the municipal tap water replenished in the dry season. The water outlet pipe 120 is connected to the tipper system to supply water for the tipper's sprinkling and dust suppression.

[0048] It should also be noted that the filter screen 20 is provided with a plurality of filter holes.

[0049] In some embodiments, the filter net 20 includes a horizontal filter segment 210 and a vertical filter segment 220; one end of the horizontal filter segment 210 is connected to the inner wall of the filter chamber 10; one end of the vertical filter segment 220 is connected to the inner wall of the filter chamber 10 and the other end is connected to the end of the horizontal filter segment 210 away from the filter chamber 10, and the vertical filter segment 220 is perpendicular to the horizontal filter segment 210.

[0050] By arranging the horizontal filter section 210 and the vertical filter section 220 to form the filter screen 20, not only is the area of ​​the filter screen 20 increased, and the volume of the buffer zone 140 is enlarged, but also a portion of the cleaning zone 150 is positioned above the horizontal filter section 210, while another portion is positioned on the side of the vertical filter section 220 near the outlet pipe 120, thereby forming a structure in which the cleaning zone 150 surrounds the filter zone. Furthermore, the water inlet pipe 110 is positioned below the horizontal filter section 210, and the vertical filter section 220 is perpendicular to the axial direction of the filter chamber 10. This reduces the chance of filtered impurities abutting against the horizontal and vertical filter sections 210, 220, and prevents clogging of the filter screen 20, thereby ensuring effective filtration.

[0051] It should be noted that the horizontal filter section 210 is parallel to the axial direction of the filter chamber 10 , and the vertical filter section 220 is perpendicular to the axial direction of the filter chamber 10 .

[0052] In some embodiments, the connection between the horizontal filter segment 210 and the vertical filter segment 220 is an arc transition.

[0053] By providing an arc transition at the connection, impurities are prevented from being retained, ensuring that the impurities can be smoothly discharged from the buffer zone 140 through the impurity discharge pipe 130 .

[0054] It should be noted that the diameter of the arc is set according to the specific dimensions of the horizontal filtration section and the vertical filtration section, and this application does not impose any specific restrictions.

[0055] In some embodiments, the cross-sectional width of the filter chamber 10 is W1, the cross-sectional width of the water inlet pipe 110 is W2, the cross-sectional width of the water outlet pipe 120 is W3, and the cross-sectional width of the impurity discharge pipe 130 is W4, wherein W1>W2, W1>W3, and W1>W4.

[0056] By setting the cross-sectional widths of the filter tube, the outlet pipe 120 and the impurity discharge pipe 130 to be smaller than the cross-sectional width of the filter chamber 10, the flow rate of water in the filter chamber 10 is reduced, thereby ensuring sufficient filtration of impurities.

[0057] It should be noted that the cross section is a cross section perpendicular to the axial direction of the filter chamber 10 .

[0058] In some embodiments, the pipeline filtering device also includes a flushing device 30 arranged on the filter chamber 10, and the flushing device 30 includes a flushing pipe 310, a female connector 320, a male connector 330 and a water supply pipe 340; the flushing pipe 310 is connected to the filter chamber 10, and the flushing pipe 310 is located above the filter mesh 20; the female connector 320 is arranged at one end of the flushing pipe 310 away from the filter mesh 20; the male connector 330 is detachably connected to the female connector 320; one end of the water supply pipe 340 is connected to the male connector 330 and the other end is connected to the water source.

[0059] The filter 20 is flushed by setting a flushing device 30, and the flushing pipe 310 is set above the filter 20, so that the water flushed by the flushing pipe 310 can flush the impurities hanging on the filter 20 into the impurity discharge pipe 130; the male connector 330 and the female connector 320 are detachably connected, which is convenient and practical. When flushing is required, the male connector 330 is connected to the female connector 320 to provide the water required for flushing the filter 20. When flushing is not required, the male connector 330 is removed.

[0060] It should be noted that the female connector 320 and the male connector 330 are quick water pipe connectors, and their specific structures and working distances are all existing technologies, which will not be described in detail in this application.

[0061] It should also be noted that when the male connector 330 is removed, that is, when the male connector 330 and the female connector 320 are not connected, water during the filtration process will not flow out of the female connector 320.

[0062] It should also be noted that the water source here can be tap water.

[0063] In some embodiments, a water inlet valve 40 is provided on the water inlet pipe 110 , a water outlet valve 50 is provided on the water outlet pipe 120 , and a waste discharge valve 60 is provided on the waste discharge pipe 130 .

[0064] By providing an inlet valve 40, an outlet valve 50, and a waste discharge valve 60, the opening and closing of the water inlet pipe 110, the water outlet pipe 120, and the waste discharge pipe 130 are controlled respectively, thereby realizing the switching between the two working states of filtering and flushing. When filtering, the inlet valve 40 and the water outlet valve 50 are opened, and the waste discharge valve 60 is closed. When cleaning, the inlet valve 40, the water outlet valve 50, and the waste discharge valve 60 are all opened, and clean tap water enters the filter chamber 10 from the flushing device 30 to flush the filter screen 20 to prevent impurities from being retained on the filter screen 20, and the flushing water and impurities are discharged through the waste discharge pipe 130.

[0065] In some embodiments, the filter chamber 10 includes a side wall 160, a first sealing plate 170 and a second sealing plate 180; the first sealing plate 170 is arranged at one end of the side wall 160; the second sealing plate 180 is arranged at the end of the side wall 160 away from the first sealing plate 170; wherein, the water inlet pipe 110 is connected to the first sealing plate 170, the water outlet pipe 120 is connected to the second sealing plate 180, and the miscellaneous pipe 130 is connected to the bottom of the side wall 160.

[0066] By arranging the water inlet pipe 110 and the water outlet pipe 120 on the first sealing plate 170 and the second sealing plate 180 respectively, the water inlet pipe 110 and the water outlet pipe 120 are respectively located on both sides of the filter screen 20, and by arranging the impurity discharge pipe 130 at the bottom of the side wall 160, impurities are discharged as much as possible.

[0067] It should be noted that the sidewall 160 can be in a cubic or cylindrical shape, and this application does not impose any specific limitations. When the sidewall 160 is in a cubic shape, the sidewall 160 includes a first side and a second side that are oppositely disposed, and a third side and a fourth side that are oppositely disposed, wherein the first side is perpendicular to the third side, the horizontal filter segment 210 is connected to the first side and the second side, respectively, and the vertical filter segment is connected to the first side, the second side, and the third side, respectively.

[0068] In some embodiments, the horizontal filter segment is connected to the first sealing plate 170 and the side wall 160 respectively, and the vertical filter segment is connected to the side wall 160 and the horizontal filter segment respectively.

[0069] The horizontal filter section is connected to the first sealing plate 170 and the side plate respectively, and the vertical filter section is connected to the side wall 160 and the horizontal filter section respectively, so as to avoid gaps between the filter screen 20 and the filter chamber 10, and to prevent water entering from the water inlet pipe 110 from not being filtered through the filter screen 20 and flowing out directly from the gap, causing impurities in the water to enter the long-term dust suppression system of the tipping machine through the water outlet pipe 120, affecting the water sprinkling effect.

[0070] In some embodiments, the connections between the side wall 160 and the first sealing plate 170 , the second sealing plate 180 , and the miscellaneous pipe 130 are all arc transitions, the connection between the first sealing plate 170 and the water inlet pipe 110 is arc transition, and the connection between the second sealing plate 180 and the water outlet pipe 120 is arc transition.

[0071] The arc transition at the connection makes all the corners in the filter chamber 10 arc-shaped, thereby preventing impurities from being trapped and ensuring that the impurities can be smoothly discharged from the buffer zone 140 through the impurity discharge pipe 130 .

[0074] It should be noted that the tipping machine includes a long-term dust suppression system and a dry fog system, and the sprinkler pipe of the long-term dust suppression system is connected to the water outlet pipe.
