Description

Technical Field

[0001] This invention relates to the field of sedimentation tank technology, specifically to a river sewage inclined tube sedimentation tank for environmental improvement and treatment. Background Technology

[0002] Inclined tube sedimentation tanks are structures used for flocculation treatment of wastewater and have wide applications in the field of wastewater treatment technology. Traditional inclined tube sedimentation tanks mainly consist of a sedimentation tank body and a mobile trolley. The mobile trolley is positioned on top of the sedimentation tank body and can move relative to it in a certain direction. The inclined tubes are arranged centrally within the sedimentation tank body, forming a tube group to divide the sedimentation tank body into an upper clear water zone and a lower sedimentation zone. After a period of use, impurities gradually accumulate and adhere to the inside of the inclined tubes. These impurities affect the sedimentation and flocculation effect of the wastewater. Therefore, it is necessary to clean the inclined tubes of the sedimentation tank body regularly to ensure its sedimentation effect. Currently, the inner wall of the inclined tubes is generally flushed manually with a water gun. Because the inner wall of the inclined tube is inclined, when the water is driven by a propeller or other device to guide the water flow rapidly, the inclined space reduces the impact force of the water flow, thus failing to effectively flush the tube wall, resulting in low cleaning efficiency and effect.

[0003] Chinese patent CN115970344B discloses a river sewage inclined tube sedimentation device for environmental improvement and treatment, including a main frame with a discharge outlet at the bottom for discharging sediment; an inclined tube assembly arranged within the main frame, containing multiple shallow sedimentation layers arranged in a linear array within the assembly, each shallow sedimentation layer including multiple inclined channels to increase the sedimentation area; and multiple cleaning belts.

[0004] The inclined tube settler uses a scraper belt to drive a pusher bar to clean the inclined channel. However, when the scraper bar cleans the inclined channel, it causes wear on the channel. This wear leads to the formation of grooves in the inclined channel, which makes it easier for sediment to accumulate. This makes it difficult for the sediment to slide off the inclined channel, requiring cleaning every once in a while, which increases costs and reduces the service life of the inclined tube assembly. Summary of the Invention

[0005] To address the aforementioned issues, a river sewage inclined tube sedimentation tank for environmental improvement and treatment is provided. By installing an angle adjustment frame within the sedimentation tank body, the inner cavity of the inclined tube body can be adjusted to extend vertically. Simultaneously, a position adjustment mechanism and a flushing mechanism are installed at the top of the sedimentation tank body, allowing the flushing component to extend longitudinally into the inclined tube, thereby achieving flushing of the inner wall of the inclined tube body. This flushing method solves the problem of existing equipment scratching the inner wall of the inclined tube body during cleaning.

[0006] To address the problems of existing technologies, this invention provides a river sewage inclined tube sedimentation device for environmental improvement and treatment, comprising a sedimentation tank body, an angle adjustment frame, an inclined tube body, a position adjustment mechanism, and a flushing mechanism.

A fourth limiting ring is provided at the top end of the outer circumferential surface of the inner tube. The second spring is sleeved on the outer circumferential surface of the inner tube and is located between the third and fourth limiting rings.

[0012] Preferably, the flushing component includes a sealing head and a nozzle. The sealing head is coaxially disposed at the bottom end of the inner tube and communicates with the inner tube.

[0016] The advantages of this invention compared to the prior art are:

[0017] This invention involves placing an angle adjustment frame inside the sedimentation tank body and mounting the inclined tube body on the angle adjustment frame. This allows the angle adjustment frame to adjust the angle of the inclined tube body, enabling the tilt angle and number of pipes to be adjusted according to the actual conditions of the river channel to meet different levels of sewage treatment needs. When cleaning the inclined tube body is required, the inner cavity of the inclined tube body is adjusted to a vertical position, and the position adjustment mechanism can drive the flushing mechanism to move at the top of the inclined tube body.

Detailed Implementation

[0029] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides:

[0031] A river sewage inclined tube sedimentation device for environmental improvement and treatment includes a sedimentation tank body 1, an angle adjustment frame 2, an inclined tube body 3, a position adjustment mechanism 4, and a flushing mechanism 5. The sedimentation tank body 1 has an inlet 11 at its lower part and an outlet 12 at its upper part. The angle adjustment frame 2 is disposed within the sedimentation tank body 1 and has an installation port that allows vertical angle adjustment. The inclined tube body 3 is disposed within the installation port and has an inclined inner cavity. The angle adjustment frame 2 can adjust the angle of the inner cavity. The position adjustment mechanism 4 is disposed at the top of the sedimentation tank body 1. The flushing mechanism 5 is disposed on the position adjustment mechanism 4 and can drive the flushing mechanism 5 to move horizontally. The flushing mechanism 5 has a flushing element 51 that can be inserted longitudinally into the inner cavity. In the sedimentation state, the inner cavity is inclined within the sedimentation tank body 1; in the flushing state, the inner cavity is vertical within the sedimentation tank body 1.

[0032] In the initial state, the angle of the inclined tube body 3 can be adjusted by the angle adjustment frame 2 to adapt to different levels of sewage treatment needs. The position adjustment mechanism 4 is activated, which drives the flushing mechanism 5 to move horizontally at the top of the sedimentation tank body 1. After the flushing component 51 moves, it is inserted into different inclined tube bodies 3. When a certain amount of sediment accumulates on the inner wall of the inclined tube body 3 and cannot slide off, the flushing component 51 is inserted into the inclined tube body 3. During the insertion process, high-pressure cleaning fluid is injected into the flushing component 51 so that the high-pressure cleaning fluid can flush the inner wall of the inclined tube body 3, so that the sediment can slide off the inner wall of the inclined tube body 3 and the inner wall of the inclined tube body is not easily scratched.

[0033] The mud discharge port 13 is located at the bottom of the sedimentation tank body 1. It is used to discharge sediment when there is a lot of sediment in the sedimentation tank body 1, so as to prevent the accumulation of sediment from affecting the sedimentation effect.

[0034] In this embodiment, the angle adjustment frame 2 is installed in the sedimentation tank body 1, and the inclined tube body 3 is installed on the angle adjustment frame 2. This allows the angle adjustment frame 2 to adjust the angle of the inclined tube body 3. The tilt angle of the inclined tube body 3 can be adjusted according to the actual situation of the river to adapt to different levels of sewage treatment needs. When the inclined tube body 3 needs to be cleaned, the inner cavity of the inclined tube body 3 is adjusted to a vertical position. The position adjustment mechanism 4 can drive the flushing mechanism 5 to move at the top of the inclined tube body 3. During flushing, the flushing mechanism 5 can extend into the inclined tube body 3 to flush the inner wall of the inclined tube body 3. The cleaning efficiency is high, and it is not easy to damage the inner wall of the inclined tube body 3. The service life of the inclined tube body 3 is long.

[0035] like Figure 2 , Figure 7 and Figure 8 As shown, the angle adjustment frame 2 includes a straight frame 21, a connecting plate 22, a rotating seat 23, a sliding seat 24, a connecting rod 25, and a sliding drive assembly. The straight frame 21 is arranged parallel to the inner wall of the sedimentation tank body 1. The connecting plate 22 is fixedly arranged on one side of the top end of the inclined tube body 3, and both ends of the connecting plate 22 are rotatably connected to the straight frame 21. The rotating seat 23 is fixedly arranged on the other side of the top end of the inclined tube body 3, and the rotating seat 23 can rotate around the connecting plate 22. The sliding seat 24 is slidably arranged in the straight frame 21 along the length direction of the straight frame 21. Both ends of the connecting rod 25 are rotatably connected to the rotating seat 23 and the sliding seat 24, respectively. When the sliding seat 24 slides on the straight rod, the sliding seat 24 drives the rotating seat 23 to rotate relative to the connecting plate 22 through the connecting rod 25.

[0036] By setting the straight frame 21 parallel to each other on opposite sides of the inner cavity of the sedimentation tank body 1, and by rotatably connecting both ends of the connecting plate 22 to the straight frame 21, and connecting the connecting plate 22 to the inclined tube body 3, the inclined tube body 3 can rotate relative to the straight frame 21. When it is necessary to adjust the angle of the inclined tube body 3, the sliding drive assembly is activated, so that the sliding drive assembly drives the sliding seat 24 to slide on the straight frame 21. The two ends of the connecting rod 25 are rotatably connected to the rotating seat 23 and the sliding seat 24 respectively. When the sliding seat 24 slides, the connecting rod 25 drives the top end of the inclined tube body 3 to rotate relative to the straight frame 21, thereby adjusting the angle of the inclined tube body 3 on the straight frame 21.

[0037] like Figure 2 As shown, the sliding drive assembly includes a support 261, a sliding rod 262, a connecting rod 263, and an electric push rod 264. The support 261 is disposed in the straight frame 21. The sliding rod 262 passes through the support 261 horizontally and slides with it. The sliding rod 262 is fixedly connected to the sliding seat 24. One end of the sliding rod 262 passes through the sedimentation tank body 1 and extends to its outer side. Both ends of the connecting rod 263 are fixedly connected to the sliding rod 262. The electric push rod 264 is horizontally disposed on the outer side of the sedimentation tank body 1. The output shaft of the electric push rod 264 is fixedly connected to the connecting rod 263.

[0038] When it is necessary to adjust the angle of the inclined tube body 3, the electric push rod 264 is activated. The output shaft of the electric push rod 264 drives the connecting rod 263 to slide on the outside of the sedimentation tank body 1, while the sliding rod 262 is slidably set on the support 261, so that the connecting rod 263 can drive the sliding rod 262 to slide in the sedimentation tank body 1. Since the sliding rod 262 is fixedly connected to the sliding seat 24, the sliding rod 262 can drive the sliding seat 24 to slide in the straight frame 21. The sliding seat 24 drives the inclined tube body 3 to rotate in the sedimentation tank body 1 through the connecting rod 25.

[0039] like Figure 4 As shown, the rinsing mechanism 5 also includes an abutment plate 52 and a telescopic tube 53. The abutment plate 52 is obliquely disposed on the position adjustment mechanism 4. The telescopic tube 53 is arranged in a rectangular array on the abutment plate 52. The rinsing component 51 is disposed at the bottom end of the telescopic tube 53. The top end of the telescopic tube 53 is connected to the water pump through a flexible pipe. In the rinsing state, the telescopic tube 53 extends downward as the internal water pressure gradually increases.

[0040] When the inclined tube body 3 is in a vertical state, its originally horizontal top end changes to an inclined position. When the abutment plate 52 moves downward, the inclined abutment plate 52 can abut and seal the top end of the inclined tube body 3. During this process, the telescopic pipe 53 is inserted into the inner cavity of the inclined tube body 3. After injecting high-pressure cleaning fluid into the telescopic pipe 53, the telescopic pipe 53 can extend. The flushing component 51 installed at the bottom end of the telescopic pipe 53 moves from the top end of the inner cavity of the inclined tube body 3 to its bottom end. During this process, the flushing component 51 can flush the inner cavity of the inclined tube body 3. At the same time, the telescopic pipe 53 can reduce the overall height of the sedimentation tank and reduce the space required for installation.

[0041] like Figure 5 and Figure 6 As shown, the telescopic pipe 53 includes an outer pipe 531, a middle pipe 532, and an inner pipe 533. The outer pipe 531 is fixedly mounted on the abutment plate 52 along the longitudinal direction. The top end of the outer pipe 531 is connected to the water pump through a flexible pipe. The middle pipe 532 is coaxially and slidably mounted in the outer pipe 531. The inner pipe 533 is coaxially and slidably mounted in the middle pipe 532. The flushing element 51 is mounted at the bottom end of the inner pipe 533.

[0042] The middle tube 532 is coaxially and slidably disposed within the outer tube 531, while the inner tube 533 is coaxially disposed within the middle tube 532. When high-pressure cleaning fluid is injected into the outer tube 531 from its bottom end, the middle tube 532 extends out from the outer tube 531, and the inner tube 533 extends out from the middle tube 532. During this process, the flushing element 51 can move from the top end to the bottom end of the inclined tube body 3, and the flushing element 51 can spray cleaning fluid horizontally, allowing the cleaning fluid to flush the inner wall of the inclined tube body 3.

[0043] like Figure 9 As shown, the telescopic tube 53 also includes a first spring 534 and a second spring 535. A first limiting ring 5311, coaxial with the bottom of the inner circumferential surface of the outer tube 531, and a second limiting ring 5321, are provided at the top of the outer circumferential surface of the middle tube 532. The first spring 534 is sleeved on the outer circumferential surface of the middle tube 532 and is located between the first limiting ring 5311 and the second limiting ring 5321. A third limiting ring 5322 is provided at the bottom of the inner circumferential surface of the middle tube 532, and a fourth limiting ring 5331 is provided at the top of the outer circumferential surface of the inner tube 533. The second spring 535 is sleeved on the outer circumferential surface of the inner tube 533 and is located between the third limiting ring 5322 and the fourth limiting ring 5331.

[0044] The lower part of the outer pipe 531 is provided with a first water outlet 5312, and the lower part of the inner pipe 533 is provided with a second water outlet 5332.

[0045] By placing the first spring 534 between the first limiting ring 5311 and the second limiting ring 5321, the middle tube 532 needs to overcome the elastic force of the first spring 534 to extend out of the outer tube 531. By placing the second spring 535 between the third limiting ring 5322 and the fourth limiting ring 5331, the inner tube 533 needs to overcome the elastic force of the second spring 535 to extend out of the middle tube 532.

[0046] When the second limiting ring 5321 moves to the bottom of the first outlet 5312, the cleaning fluid in the outer tube 531 can overflow, allowing the middle tube 532 to slide back and forth in the outer tube 531. When the fourth limiting ring 5331 moves to the bottom of the second outlet 5332, the cleaning fluid in the middle tube 532 can overflow, allowing the inner tube 533 to slide back and forth in the middle tube 532. This, in turn, allows the flushing component 51 to slide back and forth in the inclined tube body 3, thereby improving the cleaning efficiency.

[0047] like Figure 10 As shown, the flushing component 51 includes a sealing head 511 and a nozzle 512. The sealing head 511 is coaxially disposed at the bottom end of the inner tube 533 and communicates with the inner tube 533. The sealing head 511 has a mounting hole arranged circumferentially on its circumferential surface, and the nozzle 512 is disposed in the mounting hole.

[0048] The sealing head 511 is set at the bottom end of the inner tube 533, so that the sealing head 511 is connected to the inner tube 533. When the cleaning fluid in the inner tube 533 enters the sealing head 511, the cleaning fluid is sprayed out horizontally through the nozzle 512. When the sealing head 511 moves in the inclined tube body 3, the cleaning fluid can be sprayed out in a direction perpendicular to the inner wall of the inclined tube body 3, thereby rinsing the inner ring of the inclined tube body 3.

[0049] like Figure 9 As shown, the flushing component 51 is coaxially rotatably disposed at the bottom end of the inner tube 533. The flushing mechanism 5 also includes a long shaft 54, which is coaxially rotatably disposed in the inner tube 533. The bottom end of the long shaft 54 ​​passes through the flushing component 51 and is fixedly connected to it. A guide vane 541 is disposed on the circumferential surface of the long shaft 54.

[0050] By rotatably setting the long shaft 54 ​​in the inner tube 533 and fixing the bottom end of the long shaft 54 ​​to the sealing head 511, when the cleaning fluid flows in the inner tube 533, the cleaning fluid exerts a force on the guide vane 541 when it flows, so that the guide vane 541 can drive the long shaft 54 ​​to rotate in the inner tube 533, thereby causing the long shaft 54 ​​to drive the bottom end of the inner tube 533 to rotate, so that the sealing head 511 flushes the inner wall of the inclined tube body 3 in a rotating state, thereby increasing the flushing area of ​​the nozzle 512.

[0051] like Figure 9 As shown, the telescopic fitting 53 also includes a water injection plug 536 and a fixing ring 537. The water injection plug 536 is coaxially and fixedly disposed at the top end of the outer tube 531, and the fixing ring 537 is coaxially disposed at the top end of the inner circumferential surface of the middle tube 532. The fourth limiting ring 5331 elastically abuts against the bottom end of the fixing ring 537.

[0052] A water injection plug 536 is placed at the top of the outer tube 531 to prevent the middle tube 532 and the inner tube 533 from being ejected from the outer tube 531. A retaining ring 537 is placed at the top of the middle tube 532 to prevent the inner tube 533 from detaching from the middle tube 532 under the action of the second spring 535.

[0053] The fourth limiting ring 5331 elastically abuts against the bottom end of the fixing ring 537 under the action of the second spring 534. When the water injection plug 536 is installed at the top of the outer tube 531, the inner diameter of the water injection plug 536 is smaller than the diameter of the middle tube 532 and the inner tube 533. Therefore, under the constraint of the water injection plug 536, the middle tube 532 and the inner tube 533 are always located at the bottom end of the water injection plug 536.

[0054] like Figure 7 As shown, the position adjustment mechanism 4 includes a suspension 41, a first sliding platform 42, a second sliding platform 43, a tripod 44, a connecting frame 45, and a screw motor 46. The suspension 41 is arranged on both sides of the sedimentation tank body 1. The first sliding platform 42 is horizontally arranged at the top of the two suspension platforms. The second sliding platform 43 is horizontally arranged at the top of the two sliding platforms. The tripod 44 is arranged at the working end of the second sliding platform 43. The connecting frame 45 is slidably arranged at the bottom of the tripod 44 along the longitudinal direction. The abutment plate 52 is arranged at the bottom end of the connecting frame 45. The screw motor 46 is arranged longitudinally at the top of the tripod 44. The output shaft of the screw motor 46 is connected to the connecting frame 45.

[0055] The suspension 41 is used to fix the first sliding platform 42. When the first sliding platform 42 and the second sliding platform 43 are started, the tripod 44 moves horizontally at the top of the sedimentation tank body 1, while the connecting frame 45 is slidably set at the bottom of the tripod 44, so that when the lead screw motor 46 is started, the output shaft of the lead screw motor 46 can drive the connecting frame 45 to slide at the bottom of the tripod 44, so that the flushing component 51 can be inserted into the inclined tube body 3.

[0056] It should be noted that the first sliding table 42 and the second sliding table 43 are ball screw slides, synchronous belt slides or other devices whose working ends can move in a straight line. This is prior art and will not be described in detail here.

[0057] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
