Description

Technical Field

[0001] This invention relates to the field of municipal drainage pipeline technology, specifically to a sewage treatment pipeline for municipal engineering and its installation process. Background Technology

[0002] Urban sewage is treated through underground pipes, and the existing urban sewage drainage pipes cover a large area and contain many impurities.

[0003] In the prior art, in order to prevent pipe blockage, filtration shafts are installed between long-distance pipes. The shafts are dug vertically downwards and located between adjacent pipes. The sewage during transportation is settled and filtered through the shafts, thereby preventing impurities in the sewage from continuously accumulating in the pipes and causing blockage.

[0004] However, vertically excavating shafts in urban underground pipelines involves a large amount of work, easily leads to sludge accumulation, and the shafts are deep, making it difficult to clean when sewage fills them, making solid-liquid separation impossible. Furthermore, cleaning requires manual descent into the shaft, which is inefficient. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1 to 15 The present invention provides a technical solution:

[0044] Example 1:

[0045] A sewage treatment pipeline for municipal engineering includes a first pipeline 1 and a second pipeline 2, a filter settling assembly, a rotating assembly, and a cleaning assembly.

[0046] The first pipe 1 and the second pipe 2 are horizontally pre-buried underground. The first pipe 1 is located above the second pipe 2. The filter settling assembly is installed between the first pipe 1 and the second pipe 2. The filter settling assembly includes a fixing frame 3, a clamping plate 4 and a side frame 7.

[0047] The fixed frame 3 is eccentrically fitted onto the first pipe 1. The fixed frame 3 is fixedly connected to the side frame 7 from left to right. A filter frame 6 is fixedly connected to the middle of the inner side of the side frame 7. The filter frame 6 is a hollow cylindrical frame. A filter screen 15 is provided at the lower end of the filter frame 6. The side of the filter frame 6 near the side frame 7 is connected to one end of the second pipe 2. The outer arc wall of the filter frame 6 and the inner wall of the side frame 7 form a circular rotating cavity 36. The clamping plate 4 is clamped on the inner side of the fixed frame 3. A gap is left between one side of the clamping plate 4 and the filter frame 6. The sewage in the first pipe 1 flows down along the clamping plate 4 to the rotating cavity 36 at the lower end of the filter frame 6.

[0048] By setting up a filter frame 6 and a filter screen 15, the sewage in the first pipe 1 is filtered, and as the water level rises, the filtered sewage is discharged laterally along the second pipe 2.

[0049] The rotating cleaning assembly includes a rotating ring 5, an outer ring 13, and a partition 14. The outer ring 13 is fitted onto the inner wall of the side frame 7. Multiple partitions 14, which are arranged in a circular array on the inner arc of the outer ring 13, fit the outer arc of the filter frame 6. The outer ring 13 and the partitions 14 are located in the rotating cavity 36. One end of the outer ring 13 is provided with a rotating ring 5 extending to the fixed frame 3. The rotating ring 5 is driven to rotate by a drive assembly on the fixed frame 3.

[0050] By setting an outer ring 13 with partitions 14, the outer ring 13 and partitions 14 are rotated under the drive of the rotating ring 5. The filtered impurities are collected in the rotating inner cavity 36 at the lower end of the filter screen 15, and the impurities are located in the gap between adjacent partitions 14. By rotating, the impurities are rotated upward. During the upward rotation, automatic solid-liquid separation is achieved, and the impurities are rotated to the upper inner cavity of the side frame 7.

[0051] The cleaning assembly includes a pressure plate 18 and a recycling frame 8. The recycling frame 8 is fixed to the outside of the side frame 7. A fan-shaped drain port 32 is provided through the upper side wall of the side frame 7. The recycling frame 8 is connected to the upper inner cavity of the rotating inner cavity 36 through the drain port 32. The pressure plate 18 is telescopically installed on the inner side of the clamping plate 4. The pressure plate 18 is directly opposite the side wall of the partition 14 distributed in a circumferential array.

[0052] The lateral pressure of the pressure plate 18 causes the impurities at the top to be squeezed laterally along the drain outlet 32. The impurities are then laterally cleaned into the recycling box 8, which is closer to the ground, making it easier for manual collection and cleaning of the impurities in the recycling box 8, thus greatly improving the cleaning efficiency.

[0053] Example 2:

[0054] Based on embodiment 1, the fixing frame 3 is provided with an eccentric through-hole first port 24, and the clamping plate 4 is provided with a second port 29 that coincides with the first port 24. The first pipe 1 is inserted along the first port 24 and the second port 29, and the first pipe 1, the fixing frame 3 and the clamping plate 4 are fastened together by screws distributed in a circumferential array.

[0055] By setting ports on the fixing frame 3 and the clamping plate 4, the first pipe 1 can be connected for sewage discharge.

[0056] Example 3:

[0057] Based on embodiment 1, there is a gap between the outer arc wall of the clamping plate 4 and the inner wall of the fixing frame 3. A flow guide arc plate 35 is provided at the lower end of the clamping plate 4. The upper end of the flow guide arc plate 35 extends to the lower end of the second port 29. The outer wall of the flow guide arc plate 35 is set as an inclined surface extending downward. Four sets of fixing columns 26 are arranged in a circumferential array on the side wall of the filter frame 6. The other end of the fixing column 26 is fixed on the side wall of the clamping plate 4. The pressure plate 18 is in the shape of a ring. The pressure plate 18 is rotated and sleeved along the outer wall of the fixing column 26.

[0058] By setting a fixed column 26 to limit the lateral sliding position of the pressure plate 18, squeezing and displacement are prevented. By setting a guide arc plate 35, the sewage in the first pipe 1 is guided to the lower end of the filter screen 15.

[0059] Example 4:

[0060] Based on embodiment 3, multiple sets of connecting rods 20 are arranged in a circumferential array on the side wall of the outer ring 13. The middle section of the connecting rod 20 extends laterally through the gap between the clamping plate 4 and the fixing frame 3. The other end of the connecting rod 20 is fixedly connected to the rotating ring 5. The side wall of the rotating ring 5 is provided with a rotating groove 31 with a circular groove. The inner wall of the fixing frame 3 is provided with a circular protrusion 25, which is inserted into the rotating groove 31. The inner wall of the rotating ring 5 is provided with an internal gear ring 16. The outer wall of the clamping plate 4 is provided with a motor-driven drive gear 22, which meshes with the internal gear ring 16.

[0061] The engagement of the annular protrusion 25 and the rotating groove 31 achieves the purpose of limiting the rotation position of the rotating ring 5, ensuring the smooth circumferential rotation of the rotating ring 5. The engagement of the drive gear 22 and the internal gear ring 16 achieves the purpose of driving the rotation.

[0062] Example 5:

[0063] Based on embodiment 4, the side wall of the filter frame 6 is provided with a drain outlet 12, and the side frame 7 is provided with a third port 33 that is connected to the second pipe 2. The second pipe 2 is connected to the drain outlet 12 along the third port 33. The drain outlet 12 is located at the lower end of the first pipe 1 and at the upper end of the filter screen 15. The second pipe 2, the side frame 7 and the filter frame 6 are connected by screws for sealing and fastening.

[0064] The second pipe 2 is positioned and laid by setting the drain outlet 12 and the third port 33.

[0065] Example 6:

[0066] Based on embodiment 4, a folded circular airbag 17 is provided on the inner side wall of the clamping plate 4. One end of the folded circular airbag 17 is attached to the clamping plate 4, and the other end of the folded circular airbag 17 is attached to the pressure plate 18. An external air pump 21 is connected to the folded circular airbag 17, and an air inlet pipe 11 for supplying air to the air pump 21 is provided on the fixing frame 3.

[0067] Air is introduced into the folded annular airbag 17 through the air pump 21 and the air inlet pipe 11, thereby driving the pressure plate 18 to push laterally.

[0068] Example 7:

[0069] Based on embodiment 6, multiple sets of spaced exhaust ports 19 are provided on the side wall of the pressure plate 18 at the position corresponding to the drain port 32. One end of the exhaust port 19 is directly opposite the drain port 32, and the other end of the exhaust port 19 is connected to the folded circular airbag 17. An end cap 9 is provided on the upper end of the recovery frame 8, and an exhaust pipe 10 is vertically provided on the end cap 9.

[0070] By setting up an exhaust port 19 and an exhaust pipe 10, the purpose of blowing air is achieved by using the exhaust port 19. The air pressure and airflow are used to clean the impurities that have rotated to the top into the recycling box 8. At the same time, the exhaust pipe 10 is used to form a circulating air intake, which facilitates the cleaning of odors in the recycling box 8 and avoids the fermentation of impurities in the recycling box 8, which would cause gas pollution to the environment.

[0071] Example 8:

[0072] Based on embodiment 7, the upper ends of both the exhaust pipe 10 and the intake pipe 11 are bent downwards at 180 degrees. The upper end of the intake pipe 11 is provided with a dustproof protective net 27. The fixing frame 3 is provided with a connection port 23 for connecting the intake pipe 11 to the air pump 21. The clamping plate 4 is provided with a through insertion hole 30 for the air pump 21 to connect to the folded circular airbag 17.

[0073] By designing downward-bending pipe ports, dust can be prevented from clogging the pipes during air intake, and odors and fine impurities can be prevented from being sprayed directly upwards during exhaust, thus improving environmental protection.

[0074] An installation process for sewage treatment pipelines used in municipal engineering, characterized in that the installation process includes the following steps:

[0075] Pipe pre-embedding: The first pipe 1 is pre-embedded at a set height, and a fixing bracket 3 is installed at the port of the first pipe 1.

[0076] The filter assembly involves pre-assembling a filter frame 6 on the side frame 7, with the filter screen 15 on the filter frame 6 located at the lower end. A recycling frame 8 is installed on the side frame 7, and an outer ring 13 with a partition 14 is fitted onto the filter frame 6. A clamping plate 4 is connected to the other side of the filter frame 6. The side frame 7 is then mounted laterally on the outside of the fixed frame 3. The clamping plate 4, the fixed frame 3, and the first pipe 1 are connected by screws. A second pipe 2 is installed laterally at the lower end of the side frame 7.

[0077] Pre-embed backfilling: Backfill soil at the top of the assembled device so that the exhaust pipe 10 and the intake pipe 11 extend to the top of the ground and the top of the recycling frame 8 is flush with the ground.

[0078] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
