Description

Technical Field

[0001] This application belongs to the field of water treatment technology, specifically relating to a perforated sludge discharge pipe with segmented perforations. 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, resulting in high water consumption; 3. To discharge sludge from the far end, the sludge discharge time must be extended, leading to low efficiency. Summary of the Invention

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

[0005] This application discloses a segmented perforated sludge discharge pipe, comprising a pipe body with sludge discharge holes distributed axially, the pipe body having a sludge discharge outlet, the pipe body being divided into a proximal end and a distal end relative to the sludge discharge outlet, the pipe body being divided into at least two length segments axially, the sludge discharge holes in the same length segment having the same diameter and hole spacing, and:

[0006] The diameter of the sludge discharge holes in different length segments decreases gradually from the far end to the near end, or the hole spacing of the sludge discharge holes increases gradually from the far end to the near end, or the diameter of the sludge discharge holes decreases gradually from the far end to the near end while the hole spacing of the sludge discharge holes increases gradually from the far end to the near end.

[0007] Furthermore, the diameter of the mud discharge hole is 15–40 mm.

[0008] 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.

[0009] Furthermore, the spacing between the mud discharge holes is 30–80 mm.

[0010] Furthermore, the lengths of each segment may be the same or different.

[0011] Furthermore, the angle between the location of the mud discharge hole and the vertical line is no greater than 90°.

[0012] Furthermore, the pipe body has two sludge discharge zones symmetrically arranged along the axis. 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.

[0013] Furthermore, the sludge discharge holes in the same sludge discharge zone are arranged on the same straight line in the axial direction, or adjacent sludge discharge holes in the same sludge discharge zone are staggered in the axial direction.

[0014] Furthermore, the tube body is a cylindrical tube.

[0015] Furthermore, the tube body is a stepped tube, which is composed of multiple straight tubes of different diameters, either coaxially or non-coaxially, with the tube diameter gradually increasing from the distal end to the proximal end.

[0016] Beneficial effects:

[0017] This application divides the sludge discharge pipe into multiple length segments along the axial direction, 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. The diameter and spacing of the sludge discharge holes in the same length segment are the same. The diameter of the sludge discharge holes in different length segments decreases gradually from the distal end to the proximal end, or the spacing increases gradually from the distal end to the proximal end, or the diameter decreases gradually from the distal end to the proximal end while the spacing increases gradually from the distal end to the proximal end. This ensures that 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. In terms of technology, it is easy to drill holes, the processing technology is simple, and the processing efficiency is high. Attached Figure Description

[0040] like Figure 1-16 As shown, this embodiment discloses a perforated sludge discharge pipe with segmented holes, including a pipe body 1, sludge discharge holes 2 distributed along the axial direction of the pipe body 1, and 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 pipe body 1 is divided into at least two length segments in the axial direction. The diameter and spacing of the sludge discharge holes 2 in the same length segment are the same. Furthermore, the diameter of the sludge discharge holes 2 in different length segments decreases gradually from the distal end 5 to the proximal end 4, or the spacing of the sludge discharge holes 2 in different length segments increases gradually from the distal end 5 to the proximal end 4, or the diameter of the sludge discharge holes 2 in different length segments decreases gradually from the distal end 5 to the proximal end 4, while the spacing of the sludge discharge holes 2 increases gradually from the distal end 5 to the proximal end 4.

[0041] In this embodiment, the sludge discharge pipe is divided into multiple length segments along the axial direction, with the end closer to the sludge discharge outlet 3 designated as the proximal end 4 and the end farther from the sludge discharge outlet 3 designated as the distal end 5. The sludge discharge holes 2 in the same length segment have the same diameter and hole spacing. The diameter of the sludge discharge holes 2 in different length segments decreases gradually from the distal end 5 to the proximal end 4, or the hole spacing increases gradually from the distal end 5 to the proximal end 4, or the diameter decreases gradually from the distal end 5 to the proximal end 4, while the hole spacing increases gradually from the distal end 5 to the proximal end 4. This ensures that the sludge suction capacity of 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. In terms of process, it is easy to drill holes, the processing technology is simple, and the processing efficiency is high.

[0042] The diameter of a mud discharge hole refers to the size of the hole's diameter. The distance between the centers of two mud discharge holes refers to the distance between the centers of the two mud discharge holes.

[0043] In some embodiments, the diameter of the mud discharge hole 2 is 15–40 mm.

[0044] In some embodiments, the diameter of the mud discharge hole 2 at the distal end 5 is 30-40 mm, and the diameter of the mud discharge hole 2 at the proximal end 4 is 15-20 mm.

[0045] In some embodiments, the spacing between the sludge discharge holes 2 is 30–80 mm. Preferably, the spacing between two adjacent sludge discharge holes 2 at the proximal end 4 is 60.0 mm, 65.0 mm, 70.0 mm, 75.0 mm, or 80.0 mm; and the spacing between two adjacent sludge discharge holes 2 at the distal end 5 is 30.0 mm, 35.0 mm, 40.0 mm, or 45.0 mm.

[0046] In some embodiments, the lengths of the various length segments may be the same or different. Specifically, the sludge discharge pipe is divided axially, from the proximal end 4 to the distal end 5, into two length segments L1 and L2. For example, in a 6-meter sludge discharge pipe, L1 occupies 50% (3 meters), and L2 occupies 50% (3 meters); or, in a 6-meter sludge discharge pipe, length segment L1 occupies 40% (2.4 meters), and length segment L2 occupies 60% (3.6 meters). For example, refer to... Figure 1 The sludge discharge pipe is divided into three length segments L1, L2, and L3 along the axial direction, from the near end 4 to the far end 5. For example, in a 9-meter sludge discharge pipe, L1 accounts for 30% and is 2.7 meters long; L2 accounts for 40% and is 3.6 meters long; and L3 accounts for 30% and is 2.7 meters long.

[0047] In some embodiments, the tube body 1 is a cylindrical tube.

[0048] In some embodiments, the pipe body 1 is a stepped pipe, which is composed of multiple straight pipes of different diameters, coaxially or non-coaxially, with the pipe diameter gradually increasing from the distal end 5 to the proximal end 4. Each segment of the stepped pipe is a length segment, and the diameter and spacing of the sludge discharge holes vary accordingly in different segments, while the diameter and spacing of the sludge discharge holes in the same segment are the same. Since the sewage flow at the proximal end 4 of the sludge discharge pipe is the convergence point of the inflow from multiple sludge discharge holes 2, the sewage flow 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, 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.

[0049] Specifically, pipe body 1 is a cylindrical pipe, and the diameter of the mud discharge hole 2 gradually decreases from the distal end 5 to the proximal end 4. (Refer to...) Figure 1 The aperture changes, but the aperture spacing remains the same: Divide the mud discharge pipe along the axial direction, from the near end 4 to the far end 5, into three length segments L1, L2, and L3, with corresponding apertures D1, D2, and D3. The aperture of the mud discharge hole 2 increases segment by segment from the near end 4 to the far end 5, i.e., D3 > D2 > D1. For example, D3 is between 20 (excluding the end point) and 30 mm (including the end point), D2 is between 15 (excluding the end point) and 20 mm (including the end point), and D1 is between 10 and 15 mm (including the end point).

[0050] 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. (Refer to...) Figure 2 The hole spacing changes while the hole diameter remains constant: Divide the sludge discharge pipe axially from the near end 4 to the far end 5 into three length segments L1, L2, and L3, with corresponding hole spacings of S1, S2, and S3. The hole spacing of sludge discharge holes 2 increases progressively from the far end 5 to the near end 4, i.e., S3 < S2 < S1. For example, a 9-meter sludge discharge pipe divided into three length segments would have S3 of 60 mm, S2 of 70 mm, and S1 of 80 mm.

[0051] Pipe body 1 is a cylindrical pipe. The diameter of the mud discharge holes 2 gradually decreases from the distal end 5 to the proximal end 4, while the spacing between the mud discharge holes 2 gradually increases from the distal end 5 to the proximal end 4. (Refer to...) Figure 3 The diameter and spacing of the discharge pipe are changed: the sludge discharge pipe is divided into three length segments L1, L2, and L3 along the axial direction, from the near end 4 to the far end 5. The corresponding diameters are D1, D2, and D3, and the spacing is S1, S2, and S3. The diameter of the discharge hole 2 decreases segment by segment from the far end 5 to the near end 4, i.e., D3 > D2 > D1. The spacing increases segment by segment from the far end 5 to the near end 4, i.e., S3 < S2 < S1. For example, D3 is between 20 (excluding the end point) and 30 mm (including the end point), D2 is between 15 (excluding the end point) and 20 mm (including the end point), D1 is between 10 and 15 mm (including the end point), S3 is 60 mm, S2 is 70 mm, and S1 is 80 mm.

[0052] Reference Figure 5-6The pipe body 1 is composed of three straight pipes of different diameters coaxially, with the pipe diameter increasing gradually from the distal end 5 to the proximal end 4, and the diameter of the mud discharge hole 2 decreasing gradually from the distal end 5 to the proximal end 4.

[0053] Reference Figure 7-8 The pipe body 1 is composed of three coaxial straight pipes of different diameters, with the pipe diameter increasing gradually from the far end 5 to the near end 4. The hole spacing of the mud discharge holes 2 also increases gradually from the far end 5 to the near end 4.

[0054] Reference Figure 9-10 The pipe body 1 is composed of three straight pipes of different diameters coaxially. The pipe diameter increases gradually from the far end 5 to the near end 4. The diameter of the mud discharge hole 2 decreases gradually from the far end 5 to the near end 4. At the same time, the hole spacing of the mud discharge hole 2 increases gradually from the far end 5 to the near end 4.

The pipe diameter increases gradually from the far end 5 to the near end 4, and the diameter of the mud discharge hole 2 decreases gradually from the far end 5 to the near end 4.

[0056] Reference Figure 13-14 The pipe body 1 is composed of three straight pipes of different diameters and different axes. The pipe diameter increases gradually from the far end 5 to the near end 4. The hole spacing of the mud discharge hole 2 also increases gradually from the far end 5 to the near end 4.

The pipe diameter increases gradually from the far end 5 to the near end 4. The diameter of the mud discharge hole 2 decreases gradually from the far end 5 to the near end 4. At the same time, the hole spacing of the mud discharge hole 2 increases gradually from the far end 5 to the near end 4.

[0058] In some embodiments, refer to Figure 4 The angle α between the location of the mud discharge hole 2 and the vertical line is not greater than 90°, preferably 45°.

[0059] In some embodiments, refer to Figure 4 The 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.

[0060] In some embodiments, the sludge discharge holes 2 in the same sludge discharge zone are arranged in a straight line along the axial direction. In some other embodiments, adjacent sludge discharge holes 2 in the same sludge discharge zone are staggered along the axial direction. To avoid excessive hole density, which would reduce sludge discharge efficiency, the angles of two adjacent sludge discharge holes 2 are staggered; for example, one sludge discharge hole 2 is arranged at 45°, and the adjacent sludge discharge holes 2 are arranged at 60°.
