[0002] The general process of urban sewage treatment is as follows: the water inlet pump room pumps the sewage into the aeration grit tank, the water in the aeration grit tank enters the equalization tank after treatment, the sewage in the equalization tank then enters the hydrolysis acidification tank, the sewage in the hydrolysis acidification tank enters the biological reactor after treatment, and then enters the sedimentation tank for sedimentation treatment, the sewage after sedimentation is then denitrified and chlorinated, and finally discharged into nature through the water outlet pump room.

[0003] In the existing process, a fence is set around the sedimentation tank to block floating objects, and there is a water outlet trough outside the fence. The water in the sedimentation tank overflows into the water outlet trough and then enters the final sedimentation tank. However, since the water outlet trough is set in the open air, a large amount of moss will grow on the surface of the water outlet trough over time, and floating objects are easily entangled on the fence. Although a brush head is set in the water outlet trough, the brush head can only move in a certain direction, and the cleaning effect is not ideal; therefore, it does not meet the existing needs.

[0017] The present invention has the following beneficial effects:

[0018] 1. The municipal engineering sewage treatment equipment has a plurality of first protrusions distributed in an annular manner on the top of the sedimentation tank, the first protrusions are used to prevent floating objects in the sedimentation tank from entering the water outlet, the No. 1 brush head is slidably mounted on the frame, and a second protrusion is mounted on one side of the No. 1 brush head, the cross-sections of the first protrusion and the second protrusion are both semicircular, and the second protrusion is in sliding contact with the first protrusion, and when the frame rotates, the No. 1 brush head is driven to move along the water outlet, and under the joint action of the first spring and the first protrusion, the second protrusion can move up and down while moving, further driving the No. 1 brush head to move up and down while moving, so that the No. 1 brush head is fully in contact with the water outlet, effectively reducing the attachment of moss inside the water outlet, and improving the cleaning effect of the No. 1 brush head;

[0019] In addition, a second brush head is also arranged on the frame, and the second brush head is arranged adjacent to the first protrusion. Therefore, when the frame rotates, the second brush head is driven to move, thereby cleaning the first protrusion.

[0020] 2. The sewage treatment equipment for municipal engineering is provided with a rotating mechanism at the upper end of the No. 1 brush head. The rotating mechanism includes a rotating sleeve, which is rotatably mounted on the vertical rod. The rotating sleeve is fixedly connected to the No. 1 brush head. As the No. 1 brush head moves upward, the resistance to the upward movement of the resistance plate is relatively large, which causes relative movement between the No. 1 brush head and the resistance plate, further causing the pressure rod to contact the inclined block, causing the rotating sleeve to rotate. Under the action of the torsion spring, the rotating sleeve rotates back and forth, thereby driving the No. 1 brush head to rotate back and forth. In this way, the No. 1 brush head can move in a plane, move up and down, and rotate back and forth at the same time, further increasing the cleaning effect of the device on the water outlet. Moreover, the rotation direction of the No. 1 brush head is opposite to that of the frame.

[0021] In addition, a first cross bar is installed on the L-shaped rod, and the No. 2 brush head is installed on the first cross bar, and the No. 2 brush head is arranged adjacent to the first protrusion. As the resistance plate moves up and down, the first cross bar drives the No. 2 brush head to move up and down, thereby improving the cleaning effect of the first protrusion, and the No. 2 brush head is arranged in front of the movement direction of the filter residue bucket. The debris on the first protrusion is cleaned up and immediately filtered and collected by the filter residue bucket at the rear, thereby preventing the debris from further clogging the first protrusion.

[0022] 3. The municipal engineering sewage treatment equipment has a certain distance between the filter hopper and the first protrusion, so a skimming mechanism is provided on the frame, and the skimming mechanism includes a guide plate, which is installed on the frame and arranged in front of the movement direction of the second brush head. When the guide plate moves, it can change the direction of the nearby water flow, so that the nearby water flow flows to the inside of the sedimentation tank, so that the floating objects swept by the second brush head are further guided into the filter hopper along with the water flow flowing inward, so as to prevent the floating objects from further blocking the first protrusion;

[0023] In addition, the skimming mechanism also includes a paddle plate, which is arranged behind the movement direction of the second brush head and is hinged on the frame. The paddle plate is used to destroy the vortex formed behind the guide plate and paddle the floating objects swept out by the second brush head into the water flow in front of the filter residue bucket. A mounting plate is installed at the bottom end of the inclined plate, and the paddle plate is hinged on the mounting plate. A connecting rod is hinged at one end of the paddle plate, and a second cross bar is hinged at one end of the connecting rod. The second cross bar is installed on the first cross bar.

The paddle plate paddles the floating objects cleaned out by the second brush head to the movement direction of the filter residue bucket, thereby further preventing the floating objects from clogging the first protrusion.

[0037] It should be noted that the device should also include a motor for driving the frame 401 to rotate, and a water pump (the motor and the water pump are not shown) for pumping out the sludge in the sedimentation tank 100. Specifically, the principle of treating sewage in the device is that the sewage after biological reaction flows into the sedimentation tank 100 for sedimentation, the floating objects on the water surface are intercepted by the first protrusion 403, and the sludge in the water falls into the bottom of the sedimentation tank 100 after sedimentation, and then the water in the sedimentation tank 100 continuously overflows, flows into the water tank 200 through the gap between the first protrusions 403, and further flows into the final sedimentation tank 300 for the next step of sedimentation treatment. After the sedimentation in the sedimentation tank 100 is completed, the frame 401 rotates, the floating objects floating on the water surface are filtered and collected by the mobile filter hopper 404, and the scraper 402 stirs the sludge at the bottom of the sedimentation tank 100 into a flowing state, and then the sludge is pumped out by the water pump arranged at the bottom of the sedimentation tank 100.

[0038] For details, please refer to Figure 1 , Figure 2 , Fig.10 , a plurality of first protrusions 403 are distributed in an annular manner on the top of the sedimentation tank 100, a brush head 501 is slidably mounted on the frame 401, a second protrusion 507 is mounted on one side of the brush head 501, the cross-sections of the first protrusion 403 and the second protrusion 507 are both semicircular, and the second protrusion 507 is in sliding contact with the first protrusion 403, the arc surfaces of the first protrusion 403 and the second protrusion 507 slide relative to each other and collide, a sleeve 504 is mounted on the frame 401, a first spring 520 is mounted in the sleeve 504, a vertical rod 505 is slidably mounted in the sleeve 504, and one end of the vertical rod 505 is connected to one end of the first spring 520. When the frame 401 rotates, under the joint action of the first spring 520 and the first protrusion 403, the brush head 501 moves up and down. In addition, a brush head 506 is also arranged on the frame 401, and the brush head 506 is arranged adjacent to the first protrusion 403.

[0039] In this embodiment: a plurality of first protrusions 403 are distributed in an annular manner on the top of the sedimentation tank 100, and the first protrusions 403 are used to prevent floating objects in the sedimentation tank 100 from entering the water outlet trough 200. A sleeve 504 is installed on the frame 401, and the No. 1 brush head 501 is installed on the vertical rod 505, and the vertical rod 505 is slidably installed in the sleeve 504. The No. 1 brush head 501 is partially located above the water surface and partially located below the water surface. When the No. 1 brush head 501 moves downward, it can clean the underwater, and when the No. 1 brush head 501 moves upward, it can clean the surface of the water. Specifically, a second protrusion 507 is installed on one side of the No. 1 brush head 501, and the cross-sections of the first protrusion 403 and the second protrusion 507 are both semicircular, and the second protrusion 507 is in sliding contact with the first protrusion 403. When the frame 401 rotates, the frame 401 drives the No. 1 brush head 501 to move along the water outlet 200. Under the joint action of the first spring 520 and the first protrusion 403, the second protrusion 507 can move up and down while moving, further driving the No. 1 brush head 501 to move up and down while moving, thereby increasing the cleaning area of ​​the No. 1 brush head 501 for cleaning the water outlet 200, effectively reducing the attachment of moss inside the water outlet 200, and improving the cleaning effect of the No. 1 brush head 501;

[0040] In addition, a second brush head 506 is also provided on the frame 401 . The second brush head 506 is arranged adjacent to the first protrusion 403 . When the frame 401 moves, the second brush head 506 is driven to move, thereby cleaning the first protrusion 403 .

[0041] Embodiment 2: This embodiment is intended to promote the solution of the problem of further increasing the rotation function of the first brush head 501 and further increasing the up and down movement function of the second brush head. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-10 A rotating mechanism 500 is provided at the upper end of the No. 1 brush head 501. The rotating mechanism 500 includes a rotating sleeve 516. The rotating sleeve 516 is rotatably mounted on the vertical rod 505. The rotating sleeve 516 is fixedly connected to the No. 1 brush head 501, and the rotation direction of the rotating sleeve 516 is opposite to the rotation direction of the frame 401.

[0042] For details, please refer to Figure 3-8 A slider 511 is slidably installed on the vertical rod 505, and a limit block 509 is also installed on the vertical rod 505. The limit block 509 is arranged above the slider 511, and a second spring 510 is installed between the limit block 509 and the slider 511. A slide groove 513 is opened on the rotating sleeve 516, and an inclined block 518 is arranged in the slide groove 513. A pressure rod 512 is installed on one side of the slider 511, and the bottom end of the pressure rod 512 is in contact with the inclined block 518. When the pressure rod 512 presses the inclined block 518 downward, the rotating sleeve 516 will rotate, further driving the No. 1 brush head 501 to rotate.

[0043] Please refer to Figure 8 After the rotating sleeve 516 rotates, in order to reset it, a torsion spring 517 is arranged inside the rotating sleeve 516 , one end of the torsion spring 517 is fixedly mounted on the vertical rod 505 , and the other end of the torsion spring 517 is fixedly mounted on the rotating sleeve 516 .

[0044] For details, please refer to Figure 3-5 An L-shaped rod 503 is installed at one end of the slider 511. A pair of L-shaped rods 503 are provided, and the L-shaped rods 503 are symmetrically arranged on both sides of the slider 511. A resistance plate 502 is installed at one end of the L-shaped rod 503. The resistance plate 502 is located below the water surface. A water hole 514 is opened on the resistance plate 502. A rotating plate 508 is hinged on the resistance plate 502, and the rotating plate 508 is arranged adjacent to the water hole 514.

[0045] Also, please refer to Figure 6 A first cross bar 515 is installed on the L-shaped rod 503, and the second brush head 506 is installed on the first cross bar 515, and the second brush head 506 is arranged in front of the movement direction of the filter residue bucket 404, so that the second brush head 506 can move synchronously with the L-shaped rod 503, so as to achieve the effect of allowing the second brush head 506 to move up and down.

[0046] In this embodiment: a rotating mechanism 500 is provided at the upper end of the first brush head 501, and the rotating mechanism 500 includes a rotating sleeve 516, which is rotatably mounted on the vertical rod 505, and the rotating sleeve 516 is fixedly connected to the first brush head 501. Therefore, when the vertical rod 505 moves downward, the second spring 510 exerts a downward force on the slider 511. At this time, the slider 511 drives the resistance plate 502 to move downward through the L-shaped rod 503. At this time, the rotating plate 508 is opened under the resistance of water, and the movement resistance of the resistance plate 502 is reduced. At this time, the slider 511 moves downward smoothly; when the vertical rod 505 moves upward, the inclined block 518 resists The pressure rod 512, at this time, the resistance plate 502 moves upward, and the rotating plate 508 is closed, resulting in an increase in the resistance of the resistance plate 502 when it moves, so the displacement of the slider 511 is not obvious, and further, the resistance between the inclined block 518 and the pressure rod 512 is relatively large, so that the rotating sleeve 516 rotates, so as to achieve the effect of rotating and cleaning the No. 1 brush head 501. Under the action of the torsion spring 517, the rotating sleeve 516 reciprocates, thereby driving the No. 1 brush head 501 to reciprocate. Therefore, the No. 1 brush head 501 can move in a plane, move up and down, and reciprocate at the same time, further increasing the cleaning effect of the device on the water outlet 200. Moreover, the rotation direction of the No. 1 brush head 501 is opposite to the rotation direction of the frame 401, so that the No. 1 brush head 501 has a higher rotation speed relative to the water outlet 200. This design increases the relative speed between the No. 1 brush head 501 and the inner wall of the water outlet 200, thereby increasing the cleaning effect;

[0047] In addition, a first cross bar 515 is installed on the L-shaped rod 503, and the second brush head 506 is installed on the first cross bar 515. The second brush head 506 is arranged adjacent to the first protrusion 403. As the resistance plate 502 moves up and down, the first cross bar 515 drives the second brush head 506 to move up and down, thereby further improving the cleaning effect of the first protrusion 403, and the second brush head 506 is arranged in front of the movement direction of the filter residue bucket 404. Therefore, the floating objects cleaned out by the second brush head 506 will be immediately filtered and collected by the filter residue bucket 404 to prevent further clogging of the first protrusion 403.

[0048] Embodiment 3: This embodiment is intended to facilitate the solution of the problem of guiding the floating objects cleaned by the second brush head 506 into the filter hopper 404 to prevent the first protrusion 403 from being further blocked. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-10 A skimming mechanism 600 is provided on the frame 401, and the skimming mechanism 600 includes a guide plate 601, which is installed on the frame 401 and is arranged in front of the movement direction of the second brush head 506. The guide plate 601 changes the direction of the water flow in front of the second brush head 506, so that the water flow in front of the second brush head 506 flows toward the inside of the sedimentation tank 100, and the floating objects swept out by the second brush head 506 therefore flow into the filter residue bucket 404 along with the water flow flowing inward.

[0049] Also, please refer to Figure 6 , Fig. 9 The skimming mechanism 600 further includes a paddle plate 603, which is arranged at the rear of the movement direction of the guide plate 601, and is hinged on the frame 401. The paddle plate 603 is used to paddle the floating objects swept by the second brush head 506 into the filter hopper 404. The bottom end of the guide plate 601 is installed with a mounting plate 602, and the paddle plate 603 is hinged on the mounting plate 602. One end of the paddle plate 603 is hinged with a connecting rod 604, and one end of the connecting rod 604 is hinged with a second cross bar 605, which is installed on the first cross bar 515. Therefore, when the first cross bar 515 moves up and down, it drives the second cross bar 605 to move up and down. Since the two ends of the connecting rod 604 are hinged, the connecting rod 604 will drive the paddle plate 603 to paddle back and forth, thereby achieving the effect of paddle the floating objects into the water flow in front of the filter hopper 404.

[0050] In this embodiment: since there is a certain distance between the filter residue bucket 404 and the first protrusion 403, a skimming mechanism 600 is provided on the frame 401, and the skimming mechanism 600 is used to guide the floating objects swept out by the second brush head 506 into the filter residue bucket 404, and the skimming mechanism 600 includes a guide plate 601, which is installed on the frame 401, and the guide plate 601 is arranged in front of the movement direction of the second brush head 506. When moving, the guide plate 601 can guide the direction of movement of the nearby water flow, so that the water flow in front of the second brush head 506 flows toward the inside of the sedimentation tank 100, and the water flow guides the floating objects swept out by the second brush head 506 into the filter residue bucket 404, so as to prevent the floating objects from further blocking the first protrusion 403;

[0051] When the guide plate 601 moves, since the pressure of the water area behind the guide plate 601 is lower than that of the nearby water area, a vortex will be formed behind the guide plate 601. The vortex here will attract some of the floating objects swept out by the second brush head 506, which is not conducive to the floating objects flowing to the front of the filter residue bucket 404. Therefore, this embodiment is also provided with a paddle 603, which is arranged behind the movement direction of the guide plate 601. The paddle 603 is hinged on the frame 401. The paddle 603 is used to destroy the vortex that may be generated behind the guide plate 601 and to attract the floating objects swept out by the second brush head 506. The objects are pushed into the front water flow of the filter residue bucket 404, the bottom end of the guide plate 601 is installed with a mounting plate 602, and the paddle plate 603 is hinged on the mounting plate 602. One end of the paddle plate 603 is hinged with a connecting rod 604, and one end of the connecting rod 604 is hinged with a second cross bar, and the second cross bar is installed on the first cross bar 515. In this way, when the resistance plate 502 moves up and down, it can drive the paddle plate 603 to make a reciprocating movement effect. The paddle plate 603 pushes the floating objects cleaned by the second brush head 506 in the direction of movement of the filter residue bucket 404, further preventing the floating objects from further clogging the first protrusion 403.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0053] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
