[0020] Step two: preliminary treatment: when the drainage pipe is draining, the two meshing wheels in the first connecting box are used to preliminarily crush the sludge;

[0021] Step three: deep treatment: the first filter screen, the second filter screen in the device box and the holes on the conical barrel are used to deeply filter the water flow to avoid sludge accumulation.

[0022] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0023] 1. By setting a sludge removal mechanism between two drainage pipes, it forms a treatment unit, and multiple treatment units are connected in series to form a municipal drainage network, so that in specific use, the first filter screen, the second filter screen and the conical barrel in the sludge removal mechanism can filter the sewage in the drainage pipe, avoid the existence of sludge in the sewage in the drainage pipe, and the fixed block in the sludge removal mechanism can be taken out, which is convenient for processing the sludge in it, convenient for long-term use, and good use effect;

[0024] 2. When the sewage enters the inside of the first connecting box from the drainage pipe, the pressure of the sewage will make the two engaging wheels rotate, and the rotation of the two engaging wheels will crush the larger sludge in the sewage, so as to facilitate subsequent fine filtration;

[0025] 3. When the sewage passes through the first connecting hole, the sewage will also pass through the branch hole, and then flow into the inside of the connecting pipe, and then enter the inside of the open cavity. The rotation of the arc-shaped fan blade in the open cavity can drive the second rotating shaft to rotate, and the rotation of the second rotating shaft drives the transmission wheel connected therewith to rotate, thereby making the transmission belt rotate. The transmission belt makes the remaining transmission wheels rotate and drives the first rotating shaft to rotate synchronously. The rotation of the first rotating shaft makes the conical barrel and the spiral blade rotate. The rotation of the spiral blade can cut the sludge on the conical barrel, further reducing the possibility of sludge accumulation, so that the service life can be further improved;

[0026] 4. In the initial state, the first electromagnet is magnetically attracted to the first permanent magnet on the first filter screen, and at the same time, the position of the first sliding plate can make the second electromagnet magnetically attracted to the second permanent magnet at the upper end. At this time, driving the electric telescopic rod can stretch the first filter screen, thereby changing the mesh size of the first filter screen. If it is necessary to adjust the mesh size of the second filter screen, the second electromagnet and the first electromagnet are de-energized, so that they are separated from the second permanent magnet at the upper end. At this time, the first sliding plate is lowered, so that the second electromagnet at the lower end of the first sliding plate is attracted to the second electromagnet at the lower end. At the same time, the electric telescopic rod is lowered by the first sliding plate. The first electromagnet at the end of the electric telescopic rod contacts the first permanent magnet on the second filter screen, and then the first electromagnet is energized, so that the second filter screen can be stretched by the electric telescopic rod, thereby changing the mesh size of the first filter screen. By changing the mesh size of the first filter screen and the second filter screen, not only can the filtration degree when filtering the sewage be controlled, but also the two can be easily cleaned when cleaning the first filter screen and the second filter screen, and the use effect is good;

[0027] 5、When it is needed to connect the fixed block and the placing cavity, the third slide plate can be slid to make the third slide plate inserted into the inside of the second opening hole, at this time, the second piston inside the second cavity moves to the elastic block and compresses the elastic block, at the same time, since the oil passage is communicated between the second cavity and the inside of the first cavity through the first through hole, the movement of the second piston can make the first piston drive the first clamping plate to move towards the inside of the insertion hole, thereby the connection between the fixed block and the device block is completed, when it is needed to disassemble, only the third slide plate is reversely slid, thereby the device is convenient and fast to use.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without making creative labor should belong to the protection scope of the present application. Embodiment one

[0045] Please refer to Figures 1-10The utility model provides a kind of town sewer 1 network ditch sludge system, including multiple drain pipes 1 and the sludge removal structure being connected between every two adjacent drain pipes 1, the sludge removal structure includes device block 2 and the first connecting box 3 and the second connecting box 4 fixed on the both sides of device block 2, wherein, the bottom of device block 2 is provided with a placing cavity 5 in the center, and the inside of device block 2 is also provided with a first connecting hole 6 and a second connecting hole 7 in communication with the inside of placing cavity 5;

[0046] The inside of the placing cavity 5 is provided with a fixing block 8, and the outer side wall of the fixing block 8 is tightly fitted with the inner wall of the placing cavity 5. The top of the fixing block 8 is provided with a first chamber 9 in the center, and the top of the fixing block 8 is provided with a second chamber 10 on both sides of the first chamber 9. The inside of the fixing block 8 is also provided with a third connecting hole 11 for connecting the first chamber 9 and the second chamber 10. The inside of the fixing block 8 is provided with a third chamber 12 below the first chamber 9.

[0047] The other end of the first connecting hole 6 is in communication with the inside of the first chamber 9. The other end of the second connecting hole 7 is in communication with the inside of the third chamber 12.

[0048] The inside of the first chamber 9 is sequentially provided with a first filter screen 13 and a second filter screen 14 from top to bottom. The inside of the second chamber 10 is provided with a conical barrel 15 with a hollow structure. The outside of the conical barrel 15 is provided with a hole 16. The bottom of the conical barrel 15 is fixed with a first rotating shaft 17 penetrating into the inside of the third chamber 12. The inside of the first rotating shaft 17 has a hollow structure. The inside of the first rotating shaft 17 is in communication with the inside of the conical barrel 15.

[0049] In use, one sludge removal mechanism is provided between every two drain pipes 1 to form a unit. Multiple units are connected in series to form a town sewer 1 network. Taking one unit as an example, as shown in Figure 2 and Figure 3 When sewage enters the inside of the first connecting box 3 from the left drain pipe 1, the sewage can enter the inside of the first connecting hole 6 and flow into the inside of the first chamber 9 due to the communication between the left end of the first connecting hole 6 and the inside of the first connecting box 3. The sewage passes through the first filter screen 13 and the second filter screen 14 in the first chamber 9. The mesh size of the first filter screen 13 is larger than that of the second filter screen 14, so that the sewage is filtered in sequence. The filtered sewage enters the inside of the second chamber 10 through the second connecting hole 7. Then, the sewage enters the inside of the conical hole through the hole 16 on the conical barrel 15. Finally, the sewage flows out from the bottom of the first rotating shaft 17 and enters the inside of the third chamber 12. The hole diameter of the hole 16 on the conical barrel 15 is smaller than that of the second filter screen 14, so that the sewage is further filtered to avoid the accumulation of sludge in the inside of the drain pipe 1 and the blockage of the drain pipe 1.

[0050] In summary, the sludge removal mechanism is arranged between the two drainage pipes 1, and forms a treatment unit. The multiple treatment units are connected in series to form a municipal drainage pipe 1 network. In specific use, the first filter screen 13, the second filter screen 14 and the conical barrel 15 in the sludge removal mechanism can filter the sludge in the sewage in the drainage pipe 1, so that the sludge in the sewage is prevented from being present in the inside of the drainage pipe 1. Meanwhile, the fixed block 8 in the sludge removal mechanism can be taken out, so that the sludge present in the inside of the fixed block 8 can be treated, and the long-term use is facilitated, and the use effect is good.

[0051] The first connecting box 3 is internally provided with two rotating rods 18, and the rotating rods 18 are rotationally connected with the inner wall of the first connecting box 3. The rotating rods 18 are sleeved with engaging wheels 19. Figure 6 It can be seen that when the sewage enters the inside of the first connecting box 3 from the drainage pipe 1, the pressure of the sewage will make the two engaging wheels 19 rotate. The rotation of the two engaging wheels 19 will crush the larger sludge present in the sewage, so as to facilitate subsequent fine filtration. Of course, further, in order to facilitate the better rotation of the two engaging wheels 19, a driving motor or a water turbine can also be installed at the end of one of the rotating rods 18. The driving motor or the water turbine is used to drive the two engaging wheels 19 to rotate more effectively and to more effectively preliminarily process the sludge, so that the processing effect is better.

[0052] The conical barrel 15 is externally provided with a spiral blade 20. The inner top end of the third chamber 12 is rotationally connected with a second rotating shaft 23. The second rotating shaft 23 and the first rotating shaft 17 are both sleeved with transmission wheels 21. The multiple transmission wheels 21 are externally connected through a transmission belt 22. The inner bottom end of the third chamber 12 is fixedly provided with a fixed column 24. The inside of the fixed column 24 is provided with an opening cavity 25. The bottom of the second rotating shaft 23 penetrates into the inside of the opening cavity 25 and is rotationally connected with the inner bottom end of the opening cavity 25. The outside of the second rotating shaft 23 is provided with an arc-shaped fan blade 27 located in the inside of the opening cavity 25. The outside of the fixed column 24 is provided with a connecting pipe 26 in communication with the inside of the opening cavity 25. The inside of the fixed block 8 is provided with a branch hole 28. One end of the branch hole 28 is in communication with the first connecting hole 6. The other end of the branch hole 28 is in communication with the other end of the connecting pipe 26.

[0053] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8When the sewage passes through the first connecting hole 6, the sewage also passes through the branch hole 28, and then flows from the branch hole 28 to the inside of the connecting pipe 26, and then enters the inside of the open cavity 25. After the sewage enters the inside of the open cavity 25, the arc-shaped fan blade 27 inside the open cavity 25 is driven to rotate. The rotation of the arc-shaped fan blade 27 can drive the second rotating shaft 23 to rotate. The rotation of the second rotating shaft 23 drives the transmission wheel 21 connected thereto to rotate, thereby driving the transmission belt to rotate. The transmission belt 22 drives the remaining transmission wheels 21 to rotate and synchronously drives the first rotating shaft 17 to rotate. The rotation of the first rotating shaft 17 drives the conical barrel 15 and the spiral blade 20 to rotate. The rotation of the spiral blade 20 can cut the sludge on the conical barrel 15, further reducing the possibility of sludge accumulation, and further improving the service life.

[0054] The inside of the fixed block 8 is also provided with a fourth cavity 29 between the first cavity 9 and the second cavity 10. A first sliding plate 30 is slidably arranged on the inner wall of the fourth cavity 29 away from the first cavity 9. An electric telescopic rod 31 is fixed to one end face of the first sliding plate 30 towards the first cavity 9. A first electromagnet 32 is connected to the output end of the electric telescopic rod 31. Second sliding plates 33 are arranged at both ends of the first filter screen 13 and the second filter screen 14 and penetrate into the inside of the fourth cavity 29. First permanent magnets 34 are connected to the ends of the second sliding plates 33. Second electromagnets 35 are arranged at both ends of the first sliding plate 30. Second permanent magnets 36 are arranged on the inner side wall of the fourth cavity 29 and cooperate with the second electromagnets 35.

[0055] In the initial state, the first electromagnet 32 is magnetically attracted to the first permanent magnet 34 on the first filter screen 13. At the same time, the position of the first sliding plate 30 can make the second electromagnet 35 magnetically attract the second permanent magnet 36 at the upper end. At this time, driving the electric telescopic rod 31 can stretch the first filter screen 13, thereby changing the mesh size of the first filter screen 13. If it is necessary to adjust the mesh size of the second filter screen 14, the second electromagnet 35 and the first electromagnet 32 are powered off, so that they are separated from the second permanent magnet 36 at the upper end. At this time, the first sliding plate 30 is lowered, so that the second electromagnet 35 at the lower end of the first sliding plate 30 is attracted to the second electromagnet 35 at the lower end. At the same time, the electric telescopic rod 31 is lowered by the first sliding plate 30. The first electromagnet 32 at the end of the electric telescopic rod 31 contacts the first permanent magnet 34 on the second filter screen 14. Then, the first electromagnet 32 is powered on, so that the electric telescopic rod 31 can stretch the second filter screen 14, thereby changing the mesh size of the first filter screen 13. By changing the mesh size of the first filter screen 13 and the second filter screen 14, not only can the filtering degree when filtering the sewage be controlled, but also the two can be easily cleaned when cleaning the first filter screen 13 and the second filter screen 14, and the use effect is good.

[0056] The inner bottom end of the first chamber 9 is provided with a blocking plate 37, and the blocking plate 37 is fixed in an inclined state at the inner bottom end of the first chamber 9. Through the inclined blocking plate 37, the sewage after passing through the first filter screen 13 and the second filter screen 14 is affected by the blocking plate 37 to slow down, so that part of the sludge is deposited between the blocking plates 37, so as to further improve the sludge treatment effect.

[0057] The inside of the device block 2 is also provided with a first cavity 38, a second cavity 41, a first through hole 40 for communicating the first cavity 38 and the second cavity 41, a first opening 39 and a second opening 45. One end of the first opening 39 communicates with the inside of the first cavity 38, and the other end of the first opening 39 communicates with the inside of the placement cavity 5. One end of the second opening 45 communicates with the inside of the second cavity 41, and the other end of the second opening 45 communicates with the inside of the placement cavity 5. The inside of the first cavity 38 is provided with a first piston 42, and one end of the first piston 42 towards the first opening 39 is provided with a first clamping plate 43 extending into the inside of the first opening 39. The inside of the second cavity 41 is provided with a second piston 44. The bottom of the fixed block 8 is slidably provided with a third sliding plate 46, and one side of the third sliding plate 46 is provided with a second clamping plate 47 matched with the second opening 45. The fixed block 8 is also provided with a insertion hole 50 matched with the first clamping plate 43. The inside side wall of the third chamber 12 is provided with a magnet 48, and the inside side wall of the third chamber 12 and the third sliding plate 46 are both provided with a mounting hole 49. The second piston 44 and the inner wall of the second cavity 41 are also provided with an elastic block Figure 12 The shadow in the second cavity 41 is the elastic block;

[0058] As Figure 12 shown, when it is needed to connect the fixed block 8 and the placement cavity 5, the third sliding plate 46 is slidably moved so that the third sliding plate 46 is inserted into the inside of the second opening 45. At this time, the second piston 44 in the second cavity 41 moves towards the elastic block and compresses the elastic block. At the same time, since the second cavity 41 and the first cavity 38 are communicated through the first through hole 40, the movement of the second piston 44 can drive the first piston 42 and the first clamping plate 43 to move towards the inside of the insertion hole 50, thereby completing the connection between the fixed block 8 and the device block 2. When it is needed to disassemble, the third sliding plate 46 is only needed to be reversely slid, which is convenient and fast. Further, in order to improve the connection stability between the fixed block 8 and the device block 2, the mounting hole 49 and the magnet 48 can make the fixed block 8 and the device block 2 be more efficiently positioned and connected, and the use effect is better.

[0059] The bottom of the device block 2 is provided with a groove 51, and the inside of the groove 51 is provided with a third piston 53, the top of the third piston 53 is connected with the inner top end of the groove 51 through a spring 52, the bottom of the third piston 53 is provided with a hollow plate 54, and the bottom of the hollow plate 54 is provided with a bottom plate 55, the bottom of the bottom plate 55 is provided with a recess, and the inside of the recess is provided with a fourth piston 56, the bottom of the fourth piston 56 is provided with a triangular plate 57, the middle of the third piston 53 is provided with a second through hole 58 which is in communication with the inside of the hollow plate 54, and the bottom of the hollow plate 54 is in communication with the inside of the recess;

[0060] In use, since the device is buried in the ground, under its own gravity, the third piston 53 moves towards the inside of the groove 51 and compresses the spring 52, so that the air at the top of the third piston 53 enters the space above the fourth piston 56 in the inside of the bottom plate 55 through the second through hole 58, so that the fourth piston 56 descends with the triangular plate 57, and the triangular plate 57 can be inserted into the inside of the soil, so as to further improve the stability of the device as a whole, and the use effect is better.
