Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipelines, in particular to a sludge wastewater conveying pipeline. Background Art

[0002] In the process of wastewater treatment, it is necessary to transport wastewater to various treatment devices, which requires the use of water conveyance pipelines. During the process of transporting sewage through the pipeline, dirt will form in the pipeline, affecting the conveyance of sewage. Usually, a cleaning port needs to be provided on the pipeline to clean the sludge in the pipeline.

[0003] Traditional processes often open a cleaning port on the outer wall of the sludge wastewater conveying pipeline, and then fix a bent plug cover at the opening on the side wall of the pipeline through a clamp and multiple screws. When it is necessary to clean the sludge in the pipeline, the screws extending into the pipeline are unscrewed, and the plug cover is removed from the pipeline for cleaning. However, since sewage is transported, the screws are prone to rust, interfering with the opening of the plug cover. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the utility model provides a sludge wastewater conveying pipeline, and the specific technical solutions are as follows:

[0005] A sludge wastewater conveying pipeline includes a pipeline body, a cleaning port opened on one side of the pipeline body for users to clean sludge, and a plug cover detachably installed at the cleaning port. A fixing mechanism is provided between the cleaning port of the pipeline body and the plug cover. The fixing mechanism includes mounting plates fixedly arranged on both sides of the plug cover, and mounting seats fixedly arranged on both sides of the outer wall of the pipeline body and cooperating with the mounting plates in abutment. Screws for fixing are provided between the mounting plates and the mounting seats. A plurality of pressing blocks for pressing both ends of the plug cover are rotatably arranged on the outer wall of the pipeline body. An elastic mechanism for pressing and positioning the rotated pressing blocks is arranged on the outer side of the plug cover.

[0006] By adopting the above technical solutions, during the process of fixing the plug cover, the use of screws is reduced, and the screws are arranged outside the pipeline, which is convenient for the staff to disassemble and assemble, and the screws will not rust due to contact with sewage.

[0007] Optionally, a sealing member is provided at the connection between the cleaning port of the pipeline body and the plug cover. The screws are movably arranged in the mounting plates. One end of the screw is threadedly connected in the mounting seat, and the other end of the screw is fixedly provided with a hexagonal head that cooperates with and abuts against the outer wall of the mounting plate. A cross hole for the user to rotate the screw is opened in the hexagonal head.

[0008] By adopting the above technical solution, through the settings of the hexagonal head and the cross hole, it is convenient for the user to disassemble and assemble the screw in various ways such as using an electric wrench or a screwdriver, and it is also convenient for the staff to apply force during the process of removing the screw, thus facilitating the removal of the screw.

[0009] Optionally, a plurality of connecting rods are fixedly arranged on the outer wall of the pipe body. One end of each connecting rod is fixedly provided with a connecting block having a diameter larger than that of the connecting rod. The pressing block is rotatably connected between the outer walls of the connecting rod and the connecting block, and one side of the pressing block is in abutting cooperation with the outer wall of the plugging cover.

[0010] By adopting the above technical solution, the connecting rod and the connecting block can limit the pressing block. After a plurality of pressing blocks rotate and abut against the plugging cover, the two ends of the plugging cover can be pressed, so that while reducing the use of screws, the stability of the plugging cover after installation can be ensured.

[0011] Optionally, the elastic mechanism includes rubber blocks fixedly arranged at both ends of the plugging cover, and elastic pieces fixedly arranged on the outer walls of the rubber blocks and in abutting cooperation with the pressing blocks. A spherical ball is rotatably arranged at one end of the pressing block, and a positioning hole adapted to one end of the spherical ball is formed in the outer wall of the elastic piece.

[0012] By adopting the above technical solution, the rubber blocks and the elastic pieces can position the pressing block after rotation, so that the pressing block is not easily moved randomly and separated from the pressing of the plugging cover.

[0013] In summary, the present utility model has at least the following beneficial effects:

[0014] 1. By reducing the use of screws during the process of fixing the plugging cover and arranging the screws outside the pipe, it is not only convenient for the staff to disassemble and assemble, but also makes the screws not rust due to contact with sewage. Through the settings of the hexagonal head and the cross hole, it is convenient for the user to disassemble and assemble the screw in various ways such as using an electric wrench or a screwdriver, and it is also convenient for the staff to apply force during the process of removing the screw, thus facilitating the removal of the screw and convenient for the staff to clean the sludge in the pipe.

[0015] 2. By pressing the two ends of the plugging cover by the pressing blocks, while reducing the use of screws, the stability of the plugging cover after installation can be ensured. The rubber blocks and the elastic pieces can position the pressing block after rotation, so that the pressing block is not easily moved randomly and separated from the pressing of the plugging cover. Through the rotation of the spherical ball, the resistance and wear between the pressing block and the elastic piece after rotation can be reduced, and after one end of the spherical ball is inserted into the positioning hole, the pressing block after rotation can be fixed, so that the pressing block does not move after rotation, improving the stability of the pressing of the plugging cover.

Detailed implementation manners

[0022] The following further elaborates on the present utility model in conjunction with the attached Figures 1-5 drawings.

[0023] An embodiment of the present utility model discloses a sludge and wastewater conveying pipeline, referring to Figures 1-3 , including a pipe body 1, a cleaning port 11 and a plugging cover 12.

[0024] The pipe body 1 is an existing pipe for conveying sludge and wastewater, and its internal structure has been made public, so no further elaboration will be given here.

[0025] The cleaning port 11 is opened on one side of the pipe body 1, and the user can clean the sludge accumulated in the pipe body 1 from the cleaning port 11.

[0026] The plugging cover 12 is detachably installed at the cleaning port 11. The plugging cover 12 can block and seal the cleaning port 11 when the pipeline conveys sludge and wastewater. A seal 13 is provided at the connection between the cleaning port 11 of the pipe body 1 and the plugging cover 12. The seal 13 can be an object with a sealing effect such as an O-ring. The seal 13 can seal the connection between the plugging cover 12 and the cleaning port 11. A fixing mechanism is provided between the cleaning port 11 of the pipe body 1 and the plugging cover 12, and the fixing mechanism can fix the plugging cover 12 at the cleaning port 11 of the pipe body 1.

[0027] Referring to Figure 1 , Figure 2 and Figure 4, The fixing mechanism includes mounting plates 2 fixedly arranged on both sides of the plugging cover 12, and mounting seats 21 fixedly arranged on both outer sides of the outer wall of the pipe body 1 and cooperatively abutted against the mounting plates 2. A screw 22 for fixing is arranged between the mounting plate 2 and the mounting seat 21. The screw 22 is movably arranged in the mounting plate 2. One end of the screw 22 is threadedly connected in the mounting seat 21, and the other end of the screw 22 is fixedly provided with a hexagonal head 23 cooperatively abutted against the outer wall of the mounting plate 2. A cross hole 24 for the user to rotate the screw 22 is formed in the hexagonal head 23. After the screw 22 rotates, under the abutment of the hexagonal head 23 against the mounting plate 2 and the threaded connection of one end of the screw 22 to the mounting seat 21, the mounting plate 2 and the mounting seat 21 will approach each other and be fixed.

[0028] The user can use tools such as an electric wrench to rotate the hexagonal head 23 to drive the screw 22 to rotate for disassembling and assembling the screw 22. The user can also insert a screwdriver into the cross hole 24 to drive the screw 22 to rotate for disassembling and assembling the screw 22. There are various ways to disassemble and assemble the screw 22. Since the screw 22 is arranged outside the pipe, the screw 22 will not rust due to contact with sewage, and it is also convenient for the staff to apply force during the process of disassembling the screw 22, thus facilitating the removal of the screw 22 and convenient for the staff to clean the sludge in the pipe.

[0029] Refer to Figure 2 、 Figure 3 and Figure 5 , A plurality of pressing blocks 3 for pressing both ends of the plugging cover 12 are rotatably arranged on the outer wall of the pipe body 1. A plurality of connecting rods 35 are fixedly arranged on the outer wall of the pipe body 1. One end of the connecting rod 35 is fixedly provided with a connecting block 36 with a diameter larger than that of the connecting rod 35. The pressing block 3 is rotatably connected between the outer walls of the connecting rod 35 and the connecting block 36. One side of the pressing block 3 is cooperatively abutted against the outer wall of the plugging cover 12. The connecting rod 35 and the connecting block 36 can limit the pressing block 3. Since the diameter of the connecting block 36 is larger than that of the connecting rod 35, the pressing block 3 can rotate outside the connecting rod 35 and the connecting block 36 without detachment. After a plurality of pressing blocks 3 rotate and abut against the plugging cover 12, they can press both ends of the plugging cover 12, thus ensuring the stability of the plugging cover 12 after installation while reducing the use of screws 22.

[0030] Refer to Figure 2 、 Figure 3 and Figure 5 , An elastic mechanism for top-pressing and positioning the rotated pressing block 3 is arranged on the outer side of the plugging cover 12. The elastic mechanism includes rubber blocks 31 fixedly arranged at both ends of the plugging cover 12, and elastic pieces 32 fixedly arranged on the outer walls of the rubber blocks 31 and cooperatively abutted against the pressing blocks 3. The pressing block 3 can also further press the plugging cover 12 through the abutted elastic pieces 32 and rubber blocks 31 to improve the stability of the plugging cover 12 after installation, and the rubber blocks 31 and the elastic pieces 32 can top-press and position the rotated pressing block 3, making the pressing block 3 not easily move randomly and detach from the pressing of the plugging cover 12.

[0031] Reference Figure 2 , Figure 3 and Figure 5 A ball 33 is rotatably provided at one end of the pressing block 3, and a positioning hole 34 matched with one end of the ball 33 is opened on the outer wall of the spring sheet 32. The connection method between the pressing block 3 and the ball 33 is the same as the connection method of the existing ball joint rotation mechanism. Through the rotation of the ball 33, the resistance and wear between the pressing block 3 and the spring sheet 32 ​​after rotation can be reduced, and after one end of the ball 33 is inserted into the matching positioning hole 34, the rotating pressing block 3 can be fixed, so that the pressing block 3 will not move after rotation, thereby improving the stability of the pressing block 3 pressing the sealing cover 12.

[0032] The implementation principle of a sludge wastewater conveying pipeline in the embodiment of the utility model is:

[0033] When it is necessary to remove the blocking cover 12 to clean the inside of the pipe body 1, the user can press down the spring piece 32 to make one end of the ball 33 of the pressing block 3 disengage from the positioning hole 34 of the spring piece 32, and then rotate the pressing block 3 and loosen the spring piece 32. At this time, the ball 33 at one end of the pressing block 3 will abut against the loosened spring piece 32. With the continuous rotation of the pressing block 3, it will be separated from the spring piece 32 and the blocking cover 12. After the pressing block 3 held at both ends of the blocking cover 12 is rotated away;

[0034] The user can use an electric wrench or other tool to rotate the hexagonal head 23 or insert a screwdriver into the cross hole 24 and rotate it to drive the screw 22 to rotate, so that one end of the screw 22 can be unscrewed from the mounting seat 21, so that the blocking cover 12 is unfixed. At this time, people can remove the blocking cover 12 and then clean the sludge accumulated in the pipe body 1 from the cleaning port 11.
