Description

Technical Field

[0001] This application belongs to the field of water treatment technology, specifically relating to a perforated sludge discharge pipe with unevenly distributed holes. Background Technology

[0002] Perforated sludge discharge pipes are a common and crucial piece of equipment in the water treatment field, primarily used to collect and discharge sludge from the bottom of flocculation tanks, sedimentation tanks, and other similar facilities. The principle is to utilize hydrostatic pressure to evenly and effectively discharge the sludge deposited at the bottom of the tank through the perforations in the discharge pipe, thereby maintaining the normal operation and treatment efficiency of the flocculation tank, sedimentation tank, and other similar facilities.

[0003] However, the perforated sludge discharge pipe has a near end and a far end relative to the sludge discharge outlet. During the sludge discharge process, the sludge near the near end of the tank bottom has a shorter discharge path, lower resistance, stronger suction, and a larger sludge volume. Conversely, the sludge near the far end has a longer discharge path, higher resistance, weaker suction, and a smaller sludge volume. This leads to: 1. Sludge in the near-end area of ​​the tank bottom is quickly pumped out, while sludge in the far-end area cannot be effectively discharged, resulting in uneven sludge discharge; 2. While sludge is still being discharged at the far end, the near end, having already emptied its sludge, continues to discharge a large amount of clean water, increasing water consumption; 3. To discharge sludge from the far end, the sludge discharge time must be extended, resulting in low efficiency. Summary of the Invention

[0004] This application proposes a perforated mud discharge pipe with unevenly distributed holes to solve the problems of uneven mud discharge, high water consumption, and low efficiency during the mud discharge process.

[0005] This application discloses a perforated sludge discharge pipe with unevenly distributed holes, including a pipe body, wherein sludge discharge holes are distributed along the axial direction, the pipe body has a sludge discharge outlet, the pipe body is divided into a proximal end and a distal end relative to the sludge discharge outlet, and the diameter of the sludge discharge holes gradually decreases from the distal end to the proximal end.

[0006] Or the spacing between the mud discharge holes gradually increases from the far end to the near end;

[0007] Alternatively, the diameter of the sludge discharge holes may gradually decrease from the far end to the near end, while the hole spacing of the sludge discharge holes may gradually increase from the far end to the near end.

[0008] Furthermore, the diameter of the sludge discharge hole is 15–40 mm.

[0009] Furthermore, the diameter of the sludge discharge hole at the distal end is 30-40 mm, and the diameter of the sludge discharge hole at the proximal end is 15-20 mm.

[0010] Furthermore, the spacing between the mud discharge holes is 30–80 mm.

[0011] Furthermore, the tube body is a cylindrical tube.

[0012] Furthermore, the tube body is a tapered tube with a diameter that gradually increases from the distal end to the proximal end.

[0013] Furthermore, the pipe body is symmetrically provided with two sludge discharge zones along the axial direction. Each sludge discharge zone is distributed on the lower side of the pipe body, and each sludge discharge zone has multiple sludge discharge holes. The sludge discharge holes of the two sludge discharge zones are staggered.

[0014] Furthermore, the angle between the location of the mud discharge hole and the vertical line is no greater than 90°.

[0015] Furthermore, the tube body is made of ABS material or stainless steel.

[0016] Furthermore, the pipe body has sludge discharge outlets at both ends, and the diameter of the sludge discharge holes decreases from the middle of the pipe body to the sludge discharge outlets at both ends.

[0017] Beneficial effects:

[0018] This application defines the sludge discharge pipe with the end closer to the sludge discharge outlet as the proximal end and the end farther from the sludge discharge outlet as the distal end. This allows the diameter of the sludge discharge holes on the sludge discharge pipe to gradually decrease from the distal end to the proximal end, or the hole spacing to gradually increase from the distal end to the proximal end, or the diameter of the sludge discharge holes to gradually decrease from the distal end to the proximal end while the hole spacing to gradually increase from the distal end to the proximal end. This ensures that the amount of sludge absorbed by each sludge discharge hole on the sludge discharge pipe is basically equal, thereby achieving uniform and efficient removal of sludge from the bottom of the pool and reducing water consumption.

[0034] like Figure 1-9 As shown, this embodiment discloses a perforated sludge discharge pipe with unevenly distributed holes, including a pipe body 1. The pipe body 1 has sludge discharge holes 2 distributed along the axial direction. The pipe body 1 has a sludge discharge outlet 3. The pipe body 1 is divided into a proximal end 4 and a distal end 5 relative to the sludge discharge outlet 3. The diameter of the sludge discharge holes 2 gradually decreases from the distal end 5 to the proximal end 4, or the hole spacing of the sludge discharge holes 2 gradually increases from the distal end 5 to the proximal end 4, or the diameter of the sludge discharge holes 2 gradually decreases from the distal end 5 to the proximal end 4, while the hole spacing of the sludge discharge holes 2 gradually increases from the distal end 5 to the proximal end 4.

[0035] The statement that the diameter of the mud discharge hole 2 gradually decreases from the distal end 5 to the proximal end 4 refers to the continuous change in the diameter of the mud discharge hole 2 along the axial direction of the pipe body 1. The statement that the hole spacing of the mud discharge holes 2 gradually increases from the distal end 5 to the proximal end 4 refers to the continuous change in the hole spacing of the mud discharge holes 2 along the axial direction of the pipe body 1. The mud discharge hole diameter D refers to the size of the mud discharge hole. The mud discharge hole spacing S refers to the distance between the center of one mud discharge hole and the center of another mud discharge hole.

[0036] In this embodiment, the end of the sludge discharge pipe closest to the sludge discharge outlet 3 is designated as the proximal end 4, and the end furthest from the sludge discharge outlet 3 is designated as the distal end 5. This allows the diameter of the sludge discharge holes 2 to gradually decrease from the distal end 5 to the proximal end 4, or the hole spacing of the sludge discharge holes 2 to gradually increase from the distal end 5 to the proximal end 4, or the diameter of the sludge discharge holes 2 to gradually decrease from the distal end 5 to the proximal end 4, while the hole spacing of the sludge discharge holes 2 to gradually increase from the distal end 5 to the proximal end 4. This ensures that the amount of sludge absorbed by each sludge discharge hole 2 on the sludge discharge pipe is basically equal, thereby achieving uniform and efficient removal of sludge from the bottom of the pool and reducing water consumption.

[0037] In some embodiments, the diameter D of the mud discharge hole 2 is 15-40 mm.

[0038] In some embodiments, the diameter D of the mud discharge hole 2 at the distal end 5 is 30-40 mm, and the diameter D of the mud discharge hole 2 at the proximal end 4 is 15-20 mm.

[0039] In some embodiments, the hole spacing S of the sludge discharge holes 2 is 30-80 mm. Preferably, the hole spacing S between two adjacent sludge discharge holes 2 at the near end 4 is 60.0 mm, or 65.0 mm, or 70.0 mm, or 75.0 mm, or 80.0 mm; and the hole spacing S between two adjacent sludge discharge holes at the far end 5 is 30.0 mm, or 35.0 mm, or 40.0 mm, or 45.0 mm.

[0040] In some embodiments, the tube body 1 is a cylindrical tube.

[0041] In some embodiments, the pipe body 1 is a tapered pipe with a diameter that gradually increases from the distal end 5 to the proximal end 4. Since the sewage flow rate at the proximal end 4 of the sludge discharge pipe is the convergence point of the inlet water from multiple sludge discharge holes 2, the sewage flow rate at the proximal end 4 is large. Increasing the diameter of the sludge discharge pipe helps to stabilize the flow velocity of sewage in the pipe diameter, reduce water loss, facilitate the discharge of sewage at the distal end 5, and ensure the effective discharge of sludge at all points of the sludge discharge pipe.

[0042] In some embodiments, refer to Figure 1 The pipe body 1 is a cylindrical pipe, and the diameter of the mud discharge hole 2 gradually decreases from the far end 5 to the near end 4.

[0043] In some embodiments, refer to Figure 2 The pipe body 1 is a cylindrical pipe, and the spacing of the mud discharge holes 2 gradually increases from the far end 5 to the near end 4.

[0044] In some embodiments, refer to Figure 3 The pipe body 1 is a cylindrical pipe, and the diameter of the mud discharge hole 2 gradually decreases from the far end 5 to the near end 4, while the hole spacing of the mud discharge hole 2 gradually increases from the far end 5 to the near end 4.

[0045] In some embodiments, refer to Figure 5 The pipe body 1 is a tapered pipe with the diameter gradually increasing from the distal end 5 to the proximal end 4, and the diameter of the mud discharge hole 2 gradually decreasing from the distal end 5 to the proximal end 4.

[0046] In some embodiments, refer to Figure 6 The pipe body 1 is a tapered pipe with the pipe diameter gradually increasing from the distal end 5 to the proximal end 4, and the hole spacing of the mud discharge holes 2 gradually increases from the distal end 5 to the proximal end 4.

[0047] In some embodiments, refer to Figure 7 The pipe body 1 is a tapered pipe with the pipe diameter gradually increasing from the distal end 5 to the proximal end 4. The diameter of the mud discharge hole 2 gradually decreases from the distal end 5 to the proximal end 4, while the hole spacing of the mud discharge hole 2 gradually increases from the distal end 5 to the proximal end 4.

[0048] In some embodiments, refer to Figure 4 and Figure 8The pipe body 1 has two sludge discharge zones symmetrically arranged on the left and right sides along the axis. Each sludge discharge zone is distributed on the lower side of the pipe body 1. Each sludge discharge zone has multiple sludge discharge holes 2. The sludge discharge holes 2 of the two sludge discharge zones are staggered, that is, there is a corresponding sludge discharge hole 2 of sludge discharge zone B between two adjacent sludge discharge holes 2 of sludge discharge zone A.

[0049] In some embodiments, refer to Figure 4 and Figure 8 The angle α between the location of the mud discharge hole 2 and the vertical line is not greater than 90°, preferably 45°.

[0050] In some embodiments, the sludge discharge pipe is made of ABS or stainless steel, which is corrosion-resistant and has a long service life.

[0051] In another embodiment, refer to Figure 9 The pipe body 1 has two sludge discharge outlets 3, which are located at both ends of the pipe body 1. The proximal end 4 of the pipe body 1 is close to the sludge discharge outlets 3, and the distal end 5 of the pipe body 1 is far from the sludge discharge outlets 3, which is the middle part of the pipe body 1. The diameter D of the sludge discharge hole 2 decreases from the middle of the pipe body 1 towards the two sludge discharge outlets 3.

[0052] When the length of pipe 1 exceeds 10 meters, in order to improve the sludge discharge efficiency of the sludge discharge pipe and reduce the head loss caused by the long pipe 1, sludge discharge outlets 3 are respectively set at both ends of pipe 1. The diameter of the sludge discharge hole 2 decreases from the middle of pipe 1 towards the two sludge discharge outlets 3. The sludge suction capacity of each sludge discharge hole on the sludge discharge pipe is basically equal, thereby achieving uniform and efficient removal of sludge from the bottom of the pool and reducing water consumption.

[0053] The above description is only a partial embodiment of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the protection scope of this application.
