Technical Field

[0001] This application relates to the field of pipeline technology, and more specifically, to a flow guide pipe and a municipal solid waste incinerator with heat recovery function. Background Technology

[0002] Traditional pipes and fittings only have a single function of conveying goods. In industrial applications, pipes located in critical areas need to be inspected regularly for structural integrity to ensure their safe use. In fact, the inspection of pipes can directly affect normal production and workflow, slowing down daily production and work progress. Summary of the Invention

[0003] The first objective of this application is to provide a flow guide pipe fitting that can continuously monitor the structural integrity of the pipe fitting without stopping the machine for inspection, thereby facilitating the efficient operation of daily production.

Along the circumferential direction of the drive rod, the sleeve is rotatably engaged with the first sealing plate and provides a rotational seal, while the drive rod and sleeve are fixedly engaged.

[0008] The rotating wheel and the drive rod are coaxially mounted and fixedly connected.

[0009] A detection head is slidably fitted inside the blind hole, and an elastic element is installed between the detection head and the bottom wall of the blind hole. A displacement sensor is also installed on the bottom wall of the blind hole to detect the displacement of the detection head. The displacement sensor is connected to a processor. The detection head is used to abut against the inner wall of the pipe.

[0010] The drive rod is driven by the drive mechanism. The drive mechanism is used to drive the drive rod to rotate, and also to drive the drive rod to reciprocate along its axial direction.

[0011] Furthermore, the drive mechanism includes: a sleeve, a center rod, an adjusting rod, an adjuster, a first transmission assembly, a second transmission assembly, and a driver.

[0012] An extension tube is fixedly connected to one end of the pipe body where the first sealing plate is located, and the extension tube is coaxially arranged with the pipe body. The end of the extension tube away from the pipe body is closed by a second sealing plate.

[0013] The sleeve and drive rod are coaxially arranged, with the sleeve passing through the second sealing plate and the drive rod extending into the sleeve. Along the axial direction of the drive rod, the drive rod and sleeve are in sliding engagement, while the sleeve and second sealing plate are in fixed engagement. Along the circumferential direction of the drive rod, the drive rod and sleeve are in fixed engagement, while the sleeve and second sealing plate are in rotatable engagement.

[0014] The center rod is located inside the sleeve and is coaxially arranged with the sleeve. Along the axial direction of the sleeve, the center rod is fixedly fitted to the sleeve.

[0015] The drive rod is fitted with a pusher, which is located inside the extension tube, and the drive rod passes through the pusher. Along the axial direction of the drive rod, the drive rod and the pusher are fixedly fitted, while the pusher is slidably fitted into the extension tube. Along the circumferential direction of the drive rod, the drive rod and the pusher are rotatably fitted, while the pusher is fixedly fitted into the extension tube.

[0016] The adjusting rod passes through the second sealing plate and is arranged along the axial direction of the extension tube. The adjusting rod is fixedly connected to the first pushing part and the second pushing part. The first pushing part and the second pushing part are both located inside the extension tube and are respectively located at both ends of the extension tube. The pushing member is located between the first pushing part and the second pushing part.

[0017] The center rod has an external thread, and the end wall of the drive rod near the center rod has a mating hole. The mating hole extends along the axial direction of the drive rod, and the hole wall has an internal thread that mates with the external thread. The center rod and the drive rod are threadedly mated.

[0018] Both the first and second transmission assemblies are mounted on the regulator, and the adjusting rod engages with the regulator. Both the first and second transmission assemblies are also engaged with the drive unit. At any given time, only one of the first and second transmission assemblies is engaged with the center rod.

[0019] When the first transmission assembly engages with the center rod, the difference in rotational speed between the sleeve and the center rod is the first difference value. When the second transmission assembly engages with the center rod, the difference in rotational speed between the sleeve and the center rod is the second difference value. One of the first and second differences is positive, and the other is negative.

[0020] When the pusher pushes the first pusher and the second pusher, the regulator interchanges the fit between the first transmission assembly and the second transmission assembly and the center rod.

[0021] Furthermore, the regulator includes: a moving rod, a first sleeve, and a second sleeve.

[0022] The first sleeve and the second sleeve are coaxial and spaced apart.

[0023] A first magnetic element is slidably fitted inside the first sleeve. A first notch is formed on the side wall of the first sleeve, extending axially along the first sleeve. A first toothed rack is provided on the outer wall of the first sleeve, axially arranged therein. The first toothed rack is fixedly connected to the first magnetic element by a first connecting block located within the first notch.

[0024] A second magnetic component is slidably fitted inside the second sleeve. A second notch is formed on the side wall of the second sleeve, extending axially along the second sleeve. A second rack is provided on the outer wall of the second sleeve, arranged axially thereon. The second rack and the second magnetic component are fixedly connected by a second connecting block, which is located within the second notch.

[0025] One end of the moving rod is slidably fitted to the first sleeve, and the other end is slidably fitted to the second sleeve. Both the first and second transmission assemblies are mounted on the moving rod, and are located between the first and second sleeves.

[0026] An extension rod is fixedly connected to the adjusting rod, which extends to the moving rod. The extension rod, adjusting rod, and moving rod are arranged in parallel.

[0027] A groove is provided on the side of the extension rod near the moving rod, and a third rack and a fourth rack are also provided on the side of the extension rod near the moving rod. The groove, the third rack and the fourth rack are all extended along the axial direction of the extension rod.

[0028] The moving rod is fixedly connected to an adjusting arm, the end of which extends into the slide groove and slides into the slide groove.

[0029] The third rack and the first rack are driven by the first transmission gear, and the fourth rack and the second rack are driven by the second transmission gear.

[0030] The first pushing part is located on the side of the second pushing part closer to the tube body, the first sleeve is located on the side of the second sleeve closer to the tube body, and the first transmission assembly is located on the side of the second transmission assembly closer to the tube body.

[0031] When the second transmission component is engaged with the central rod transmission: the adjusting arm is attached to the end of the slide groove near the tube body, the first connecting block is located at the end of the first notch near the first transmission component, the first magnetic element is magnetically attracted to the moving rod, the second connecting block is located at the end of the second notch away from the first transmission component, the second magnetic element is separated from the moving rod, and the pushing element moves toward the second pushing part.

[0032] After the pusher pushes the second pusher: the second transmission assembly is about to separate from the center rod, the first transmission assembly is about to engage with the center rod, the first magnetic component separates from the moving rod and moves away from it, and the second magnetic component moves closer to the moving rod. The distance between the first magnetic component and the moving rod is greater than the distance between the second magnetic component and the moving rod. The second magnetic component drives the moving rod towards it through magnetic attraction, thereby engaging the first transmission assembly with the center rod.

[0033] When the first transmission component is engaged with the central rod transmission: the adjusting arm is attached to the end of the slide groove away from the tube body, the first magnetic component is separated from the moving rod, the second magnetic component is magnetically attracted to the moving rod, and the pushing component moves toward the first pushing part.

[0034] After the pushing component pushes the first pushing part: the first transmission assembly is about to separate from the central rod, the second transmission assembly is about to engage with the central rod, the second magnetic component separates from the moving rod and moves away from the moving rod, and the first magnetic component moves closer to the moving rod. The distance between the first magnetic component and the moving rod is smaller than the distance between the second magnetic component and the moving rod. The first magnetic component drives the moving rod towards the first magnetic component through magnetic attraction, so that the second transmission assembly engages with the central rod.

[0035] Furthermore, the end of the detection head is wedge-shaped and made of a wear-resistant material for cleaning the inner wall of the pipe.

[0036] Furthermore, a filter plate is also provided inside the pipe body, and the drive rod passes through the filter plate. The filter plate is located on the side of the rotating wheel near the first sealing plate.

[0037] Furthermore, the filter plate includes: an annular plate, a conical plate, and a cap.

[0038] The outer diameter of the annular plate matches the inner diameter of the pipe body, and the inner diameter of the annular plate is larger than the outer diameter of the drive rod. The annular plate is fixedly connected to the pipe body.

[0039] The conical plate is cone-shaped, and the bottom diameter of the conical plate matches the inner diameter of the annular plate. The conical plate and the annular plate are coaxially arranged, and the bottom periphery of the conical plate is fixedly connected to the inner periphery of the annular plate.

[0040] The top of the conical plate is positioned towards the side furthest from the first sealing plate.

[0041] The tapered plate is fitted with a guide sleeve, which passes through the top of the tapered plate and is coaxially arranged with the tube body. The drive rod passes through the guide sleeve.

[0042] Along the axial direction of the drive rod, the drive rod slides and seals with the guide sleeve, while the guide sleeve is fixedly fitted with the tapered plate. Along the circumferential direction of the drive rod, the drive rod is fixedly fitted with the guide sleeve, while the guide sleeve rotates and seals with the tapered plate.

[0043] The cap body and the tube body are coaxially arranged, and the guide sleeve passes through the cap body and is fixedly connected to the cap body.

[0044] The cap body is provided with a first extension arm and a second extension arm.

[0045] The first extension arm is fixedly connected to the cap body and extends along the generatrix of the conical plate, and the first extension arm is in contact with the outer surface of the conical plate.

[0046] The second extension arm is fixedly connected to the end of the first extension arm away from the cap body. The second extension arm extends radially along the annular plate and is in contact with the surface of the annular plate away from the first sealing plate.

[0047] Furthermore, the pipe body is also equipped with a slag discharge pipe, which is connected to the pipe body. The slag discharge pipe is located on the side of the annular plate away from the first sealing plate, and is positioned close to the surface of the annular plate. The slag discharge pipe is equipped with a control valve.

[0048] A municipal solid waste incinerator with heat recovery function includes: an incinerator body, heat exchange tubes, and the aforementioned flow guide pipes.

[0049] The heat exchange tubes are located inside the flue gas passage of the incinerator body.

[0050] The inlet end of the heat exchange tube is connected to the heat exchange medium supply end, and the outlet end of the heat exchange tube is connected to the end of the guide tube body furthest from the first sealing plate. The heat exchange tube and the tube body are coaxially arranged, and their inner diameters are the same. The rotating wheel is located inside the heat exchange tube.

[0051] The beneficial effects of the technical solutions in this application include: During use, if the inner walls of the pipe body and the target pipeline are regular, without deformation, defects, or protrusions, then during the rotation of the wheel, the detection head will not shift axially along each mating blind hole. In this case, the displacement sensor will detect zero displacement of the detection head. Therefore, the processor can determine whether the inner walls of the pipe body and the target pipeline are regular by using the detection data from the displacement sensor, thereby enabling monitoring of the internal structural integrity of the pipe body and the target pipeline without stopping the system.

[0052] When used for conveying liquid material mixtures, the rotating wheel can simultaneously agitate the liquid material mixture, ensuring its uniformity and reducing the probability of stratification or solid particle deposition during the conveying process.

[0053] When used to transport heat exchange medium phases, if the target pipeline is a heat exchange tube, the rotating wheel can promote the heat exchange medium (especially liquid heat exchange medium) to rotate while flowing, thereby forming a vortex. Centrifugal force is used to make the heat exchange medium better contact with the inner wall of the target pipeline, thereby optimizing the heat exchange effect.

[0054] Overall, the flow guide pipe provided in this application embodiment can continuously monitor the structural integrity of the pipe without stopping the machine for inspection, which helps to carry out daily production work efficiently.

[0055] The municipal solid waste incinerator with heat recovery function provided in this application embodiment can continuously monitor the structural integrity of the heat exchange pipeline without stopping the machine for inspection, which helps to carry out daily production work efficiently.

[0063] Furthermore, the terms "vertical" and "parallel" do not mean that the parts must be absolutely vertical or parallel, but can be slightly tilted.

[0064] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0065] The technical solutions of this application will be described by way of example through some embodiments below.

[0066] See Figures 1-3 This application provides a flow guide pipe, which includes: a pipe body 100, a rotating wheel 200, a drive rod 300, a drive mechanism, and a processor (not shown in the figure).

[0067] One end of the pipe body 100 is closed by the first sealing plate 110, and the side wall of the pipe body 100 has an opening 120. The opening 120 is located close to the first sealing plate 110 and serves as the outlet of the pipe body 100. The end of the pipe body 100 away from the first sealing plate 110 serves as the inlet of the pipe body 100.

[0068] The drive rod 300 is coaxially arranged with the tube body 100. The drive rod 300 has a rod sleeve 310, which is sleeved on the drive rod 300 and passes through the first sealing plate 110.

[0069] Along the axial direction of the drive rod 300, the sleeve 310 is fixedly engaged with the first sealing plate 110, while the drive rod 300 and sleeve 310 are slidably engaged and provide a sliding seal. Along the circumferential direction of the drive rod 300, the sleeve 310 and the first sealing plate 110 are rotatably engaged and provide a rotatable seal, while the drive rod 300 and sleeve 310 are fixedly engaged. In this embodiment, the inner end face of the sleeve 310 and the inner surface of the first sealing plate 110 are located on the same plane.

[0070] The rotating wheel 200 is cylindrical and is coaxially and fixedly connected to the drive rod 300.

[0071] The rotating wheel 200 has a mating blind hole on its surface. The mating blind hole is arranged radially along the rotating wheel 200, and multiple mating blind holes are evenly spaced along the circumference of the rotating wheel 200.

[0072] A detection head 210 is slidably fitted inside the blind hole, and the detection head 210 slides and seals against the wall of the blind hole. An elastic element 220 is provided between the detection head 210 and the bottom wall of the blind hole. In its natural state, under the elastic force of the elastic element 220, part of the detection head 210 extends out of the blind hole.

[0073] A displacement sensor (not shown in the figure) is also provided on the bottom wall of the blind hole. The displacement sensor is used to measure the displacement of the detection head 210 sliding along the blind hole. The displacement sensor is connected to the processor (optionally wirelessly, but not limited to this).

[0074] The drive rod 300 is driven by the drive mechanism. The drive mechanism is used to drive the drive rod 300 to rotate, and also to drive the drive rod 300 to reciprocate along its axial direction.

[0075] When in use, the inlet of the guide pipe is connected to the input pipe (the input pipe connected to the inlet of the guide pipe is referred to as the object pipe in the following text), and the outlet is connected to the output pipe.

[0076] When the drive mechanism is activated, the rotating wheel 200 rotates and reciprocates along the axial direction of the pipe body 100. By adjusting the amplitude of the axial movement of the rotating wheel 200 driven by the drive mechanism, the rotation wheel 200 can be controlled to move only within the target pipe, only within the pipe body 100, or simultaneously within both the target pipe and the pipe body 100.

[0077] In this embodiment, the diameter of the rotating wheel 200 is smaller than the inner diameter of the pipe body 100 and also smaller than the inner diameter of the target pipe. When the rotating wheel 200 is inside the pipe, the detection head 210 is used to abut against the inner wall of the pipe. The detection head 210 is pushed into the mating blind hole of the rotating wheel 200, thereby reducing the extension length of the detection head 210 and the elastic member 220 is in an elastic compression state.

[0078] If the inner walls of the pipe body 100 and the target pipe are regular, without deformation, defects, or protrusions, then during the movement of the rotating wheel 200, the detection head 210 will not displace along the axial direction of each mating blind hole. In this case, the displacement sensor will detect zero displacement of the detection head 210. Therefore, the processor can determine whether the inner walls of the pipe body 100 and the target pipe are regular by using the detection data from the displacement sensor, thereby enabling monitoring of the internal structural integrity of the pipe body 100 and the target pipe in a non-stop state.

[0079] In practical applications, flow guide pipes can be used in a variety of scenarios, including but not limited to: conveying liquid material mixtures and conveying heat exchange media.

[0080] When used for conveying liquid material mixtures, the rotating wheel 200 can simultaneously agitate the liquid material mixture, ensuring its uniformity and reducing the probability of stratification or solid particle deposition during conveying.

[0081] When used to transport heat exchange medium phases, if the target pipeline is a heat exchange tube, the rotating wheel 200 can promote the heat exchange medium (especially liquid heat exchange medium) to rotate while flowing, thereby forming a vortex. Centrifugal force is used to make the heat exchange medium better contact the inner wall of the target pipeline, thereby optimizing the heat exchange effect.

[0082] Overall, the flow guide pipe provided in this application embodiment can continuously monitor the structural integrity of the pipe without stopping the machine for inspection, which helps to carry out daily production work efficiently.

[0083] In this embodiment, please refer to Figure 4 The drive mechanism includes: sleeve 400, center rod 410, adjusting rod 330, adjuster, first transmission assembly 510, second transmission assembly 520 and driver (not shown in the figure).

[0084] An extension tube 130 is fixedly connected to one end of the tube body 100 where the first sealing plate 110 is located. The extension tube 130 is coaxially arranged with the tube body 100. The end of the extension tube 130 away from the tube body 100 is closed by the second sealing plate 140.

[0085] The sleeve 400 is coaxially arranged with the drive rod 300 and the sleeve 400 passes through the second sealing plate 140. In this embodiment, the inner end face of the sleeve 400 and the inner side face of the second sealing plate 140 are located on the same plane.

[0086] The drive rod 300 extends into the sleeve 400. Along the axial direction of the drive rod 300, the drive rod 300 and the sleeve 400 are in sliding engagement, and the sleeve 400 is in fixed engagement with the second sealing plate 140. Along the circumferential direction of the drive rod 300, the drive rod 300 and the sleeve 400 are in fixed engagement, and the sleeve 400 and the second sealing plate 140 are in rotatable engagement.

[0087] The sleeve 400 is driven by the power output shaft of the driver. Optionally, the sleeve 400 and the power output shaft of the driver are driven by gears, but this is not limited to this.

[0088] The center rod 410 is located inside the sleeve 400 and is coaxially arranged with the sleeve 400. The diameter of the center rod 410 is smaller than the inner diameter of the sleeve 400. Along the axial direction of the sleeve 400, the center rod 410 is fixedly fitted to the sleeve 400. Along the circumferential direction of the sleeve 400, the center rod 410 is rotatably fitted to the sleeve 400.

[0089] The end of the center rod 410 away from the drive rod 300 extends beyond the sleeve 400. The center rod 410 is coaxially fixedly connected to a mating gear 420, which is located outside the sleeve 400.

[0090] The drive rod 300 is fitted with a pusher 320, which is located inside the extension tube 130, and the drive rod 300 passes through the pusher 320. Along the axial direction of the drive rod 300, the drive rod 300 and the pusher 320 are fixedly engaged, and the pusher 320 is slidably engaged in the extension tube 130. Along the circumferential direction of the drive rod 300, the drive rod 300 and the pusher 320 are rotatably engaged, and the pusher 320 is fixedly engaged in the extension tube 130.

[0091] The adjusting rod 330 passes through the second sealing plate 140 and is arranged along the axial direction of the extension tube 130. The adjusting rod 330 is fixedly connected to the first pushing part 331 and the second pushing part 332. The first pushing part 331 and the second pushing part 332 are both located inside the extension tube 130 and are respectively located at both ends of the extension tube 130. The pushing member 320 is located between the first pushing part 331 and the second pushing part 332.

[0092] In this embodiment, the first pushing part 331 is located on the side of the second pushing part 332 near the tube body 100.

[0093] The center rod 410 has an external thread, and the end wall of the drive rod 300 near the center rod 410 has a mating hole. The mating hole extends along the axial direction of the drive rod 300, and the hole wall has an internal thread that mates with the external thread. The center rod 410 and the drive rod 300 are threadedly mated.

[0094] Both the first transmission assembly 510 and the second transmission assembly 520 are mounted on the regulator, and the adjusting rod 330 cooperates with the regulator. Both the first transmission assembly 510 and the second transmission assembly 520 are respectively connected to the driver. At any given time, only one of the first transmission assembly 510 and the second transmission assembly 520 is connected to the center rod 410.

[0095] When the first transmission assembly 510 engages with the gear 420 of the center rod 410, the difference in rotational speed between the sleeve 400 and the center rod 410 is the first difference (i.e., first difference = rotational speed of sleeve 400 - rotational speed of center rod 410). When the second transmission assembly 520 engages with the gear 420 of the center rod 410, the difference in rotational speed between the sleeve 400 and the center rod 410 is the second difference (i.e., second difference = rotational speed of sleeve 400 - rotational speed of center rod 410). One of the first and second differences is positive, and the other is negative.

[0096] When the pusher 320 pushes the first pusher 331 and the second pusher 332, the adjuster interchanges the cooperation relationship between the first pusher 331 and the second pusher 332 and the center rod 410.

[0097] For example, when the second transmission assembly 520 engages with the gear 420 of the central rod 410 (while the first transmission assembly 510 is disengaged from the gear 420 of the central rod 410), a speed difference exists between the sleeve 400 and the central rod 410, while the sleeve 400 and the drive rod 300 rotate at the same speed. This means a speed difference exists between the drive rod 300 and the central rod 410. Consequently, under the action of the thread, axial relative movement occurs between the drive rod 300 and the central rod 410.

[0098] In this embodiment, when the second transmission component 520 engages with the mating gear 420 of the center rod 410, the drive rod 300 moves into the sleeve 400 (achieved by setting the helical direction of the thread). The drive rod 300 drives the pusher 320 to move towards the side where the second pusher 332 is located. Finally, the pusher 320 pushes the second pusher 332, thereby pushing the adjusting rod 330. In this way, the adjusting rod 330 can trigger the regulator, which then interchanges the engagement relationship between the first transmission component 510 and the second transmission component 520 and the mating gear 420 of the center rod 410. That is, the second transmission component 520 is disconnected from the mating gear 420, and the first transmission component 510 is engaged with the mating gear 420.

[0099] In this way, the relative rotation direction between the drive rod 300 and the central shaft will be opposite to before, causing the drive rod 300 to retract from the sleeve 400. The pusher 320 also moves in the opposite direction until the pusher 320 pushes the first pusher 331. The adjusting rod 330 then triggers the adjuster again, which reverses the engagement relationship between the first transmission assembly 510 and the second transmission assembly 520 and the mating gear 420 of the central rod 410. That is, the first transmission assembly 510 is disconnected from the mating gear 420, and the second transmission assembly 520 is engaged with the mating gear 420. In this way, the reciprocating motion of the drive rod 300 in the axial direction can be achieved.

[0100] Specifically, the regulator includes: a moving rod 500, a first sleeve 610, and a second sleeve 620.

[0101] The first sleeve 610 and the second sleeve 620 are coaxially and spaced apart. Both the first sleeve 610 and the second sleeve 620 are parallel to the central rod 410. In this embodiment, the guide pipe also includes a frame (not shown in the figure), which is fixedly connected to the pipe body 100, and the first sleeve 610 and the second sleeve 620 are both fixedly installed on the frame.

[0102] A first magnetic element 611 is slidably fitted inside the first sleeve 610. A first notch 612 is formed on the side wall of the first sleeve 610, extending axially along the first sleeve 610. A first toothed rack 613 is provided on the outer wall of the first sleeve 610, arranged axially thereal. The first toothed rack 613 is fixedly connected to the first magnetic element 611 by a first connecting block 614, which is located within the first notch 612.

[0103] A second magnetic element 621 is slidably fitted inside the second sleeve 620. A second notch 622 is formed on the side wall of the second sleeve 620, extending axially along the second sleeve 620. A second rack 623 is provided on the outer wall of the second sleeve 620, arranged axially thereal. The second rack 623 and the second magnetic element 621 are fixedly connected by a second connecting block 624, which is located within the second notch 622.

[0104] The moving rod 500, the first sleeve 610, and the second sleeve 620 are coaxially arranged. One end of the moving rod 500 is slidably fitted to the first sleeve 610, and the other end is slidably fitted to the second sleeve 620. The first transmission assembly 510 and the second transmission assembly 520 are both mounted on the moving rod 500, and the first transmission assembly 510 and the second transmission assembly 520 are located between the first sleeve 610 and the second sleeve 620.

[0105] The first sleeve 610 is located on the side of the second sleeve 620 closer to the pipe body 100, and the first transmission assembly 510 is located on the side of the second transmission assembly 520 closer to the pipe body 100.

[0106] The first sleeve 610, the first connecting block 614, the first rack 613, the second sleeve 620, the second connecting block 624, and the second rack 623 are all made of non-magnetic materials. The two ends of the center rod 410 are made of magnetic materials.

[0107] An extension rod 340 is fixedly connected to the adjusting rod 330, and the extension rod 340 extends to the moving rod 500. The extension rod 340, the adjusting rod 330, and the moving rod 500 are arranged in parallel.

[0108] The extension rod 340 has a groove 341 on the side near the moving rod 500. A third rack 342 and a fourth rack 343 are also provided on the same side of the extension rod 340. The groove 341, the third rack 342, and the fourth rack 343 all extend axially along the extension rod 340. In this embodiment, the groove 341 is located between the third rack 342 and the fourth rack 343, with the third rack 342 located on the side of the fourth rack 343 closest to the tube body 100.

[0109] An adjusting arm 530 is fixedly connected to the moving rod 500. The adjusting arm 530 is arranged perpendicular to the moving rod 500 and extends toward the extension rod 340. The end of the adjusting arm 530 extends to the slide groove 341. Along the axial direction of the extension rod 340, the end of the adjusting arm 530 is slidably engaged with the slide groove 341.

[0110] A first transmission gear 710 is provided between the third rack 342 and the first rack 613. Both the third rack 342 and the first rack 613 mesh with the first transmission gear 710, and the third rack 342 and the first rack 613 are driven together by the first transmission gear 710.

[0111] A second transmission gear 720 is provided between the fourth rack 343 and the second rack 623. Both the fourth rack 343 and the second rack 623 mesh with the second transmission gear 720, and the fourth rack 343 and the second rack 623 are driven together by the second transmission gear 720.

[0112] Both the first transmission gear 710 and the second transmission gear 720 are mounted on the frame.

[0113] It should be noted that both the first transmission assembly 510 and the second transmission assembly 520 can be selected as gear sets, and the transmission ratios of the first transmission assembly 510 and the second transmission assembly 520 are different. However, this is not the only possibility.

[0114] In this embodiment, the power output shaft of the driver is arranged parallel to the moving rod 500. Optionally, the first transmission component 510 and the second transmission component 520 can be driven and engaged with the power output shaft of the driver via a spline structure. With this design, when the first transmission component 510 and the second transmission component 520 move along the axial direction of the power output shaft of the driver with the moving rod 500, they can maintain the transmission engagement relationship with the power output shaft of the driver. However, this is not the only possible arrangement.

[0115] The specific working principle is as follows: (1) When the second transmission assembly 520 and the center rod 410 are engaged by the gear 420: the adjusting arm 530 is attached to the end of the slide groove 341 near the tube body 100, the first connecting block 614 is located at the end of the first notch 612 near the first transmission assembly 510, the first magnetic element 611 is magnetically attracted to the moving rod 500, the second connecting block 624 is located at the end of the second notch 622 away from the first transmission assembly 510, and the second magnetic element 621 is separated from the moving rod 500. At this time, the driver is activated, the driving rod 300 moves into the sleeve 400, and the pushing element 320 moves towards the second pushing part 332. Figure 1 , Figure 2 and Figure 4 As shown; (2) After the pusher 320 pushes the second pusher 332: the extension rod 340 moves synchronously with the adjusting rod 330. The extension rod 340 uses the end wall of the slide groove 341 near the tube body 100 to push the moving rod 500, causing the moving rod 500 to move towards the side where the second sleeve 620 is located. During this process, the gear of the first transmission assembly 510 gradually approaches the mating gear 420. When the pusher 320 pushes the second pusher 332 to its position, the gear of the second transmission assembly 520 is about to separate from the mating gear 420 of the center rod 410, while the gear of the first transmission assembly 510 is about to engage with the mating gear 420 of the center rod 410. Figure 5 , Figure 6 and Figure 7 As shown. At this time, the third rack 342 drives the first rack 613 through the first transmission gear 710, causing the first magnetic element 611 to separate from and move away from the moving rod 500. The fourth rack 343 drives the second rack 623 through the second transmission gear 720, causing the second magnetic element 621 to move closer to the moving rod 500, and the distance between the first magnetic element 611 and the moving rod 500 is greater than the distance between the second magnetic element 621 and the moving rod 500. The first magnetic element 611 and the second magnetic element 621 are selected as magnetic elements of the same size and magnetic force. Due to the different distances between the first magnetic element 611 and the second magnetic element 621 and the moving rod 500, the second magnetic element 621 has a greater magnetic attraction to the moving rod 500. The second magnetic element 621 drives the moving rod 500 further towards the second magnetic element 621 through magnetic attraction, so that the first transmission assembly 510 and the mating gear 420 are engaged in transmission, while the second transmission assembly 520 and the mating gear 420 are completely separated. Figure 8 As shown. At this time, the adjusting arm 530 is in contact with the end of the slide groove 341 that is away from the tube body 100; (3) When the first transmission assembly 510 and the center rod 410 are in transmission cooperation: the adjusting arm 530 is attached to the end of the slide groove 341 away from the tube body 100, the first magnetic element 611 is separated from the moving rod 500, and the second magnetic element 621 is magnetically attracted to the moving rod 500. At this time, the relative rotation direction of the driving rod 300 and the center rod 410 changes, the driving rod 300 is withdrawn from the sleeve 400, and the pushing element 320 moves toward the first pushing part 331; (4) After the pusher 320 pushes the first pusher 331 to its position: the first transmission assembly 510 is about to separate from the center rod 410, the second transmission assembly 520 is about to engage with the center rod 410, the fourth rack 343 drives the second rack 623 through the second transmission gear 720, causing the second magnetic element 621 to separate from the moving rod 500 and move away from the moving rod 500, and the third rack 342 drives the first rack 613 through the first transmission gear 710, causing the first magnetic element 611 to move closer to the moving rod 500. The extension rod 340 uses the end wall of the groove 341 away from the tube body 100 to push the moving rod 500, causing the moving rod 500 to move towards the side where the first sleeve 610 is located. Because the distance between the first magnetic element 611 and the moving rod 500 is smaller than the distance between the second magnetic element 621 and the moving rod 500, the first magnetic element 611 drives the moving rod 500 to move towards the first magnetic element 611 through magnetic attraction, so that the second transmission assembly 520 engages with the gear 420 of the central rod 410, and then disengages from the gear 420 of the central rod 410. At this point, it returns to... Figure 1 , Figure 2 and Figure 4 The state shown.

[0116] By repeating this process, the drive rod 300 can achieve reciprocating motion in the axial direction.

[0117] With the above design, all related functions can be achieved with only a single power input from the driver.

[0118] In this embodiment, the end of the detection head 210 is wedge-shaped and made of a wear-resistant material, so as to simultaneously clean the inner wall of the target pipe or the pipe body 100.

[0119] Correspondingly, please refer to Figure 2 and Figure 9 The pipe body 100 is also equipped with a filter plate, and the drive rod 300 passes through the filter plate. The filter plate is located on the side of the rotating wheel 200 near the first sealing plate 110. With this design, the filter plate can filter impurities in the liquid material mixture or heat exchange medium, and can also filter impurities cleaned off the inner wall of the pipe by the detection head 210.

[0120] Optionally, the filter plate may also be configured to include: an annular plate 810, a conical plate 820, and a cap 840.

[0121] The outer diameter of the annular plate 810 matches the inner diameter of the pipe body 100, and the inner diameter of the annular plate 810 is larger than the outer diameter of the drive rod 300. The annular plate 810 is fixedly connected to the pipe body 100.

[0122] The conical plate 820 is cone-shaped; in other words, the conical plate 820 can be seen as a flat plate bent into a cone shape.

[0123] The bottom diameter of the conical plate 820 matches the inner diameter of the annular plate 810. The conical plate 820 and the annular plate 810 are coaxially arranged, and the bottom periphery of the conical plate 820 is fixedly connected to the inner periphery of the annular plate 810.

[0124] The top of the conical plate 820 is positioned toward the side away from the first sealing plate 110.

[0125] The conical plate 820 is fitted with a guide sleeve 830, which passes through the top of the conical plate 820 and is coaxially arranged with the tube body 100. The drive rod 300 passes through the guide sleeve 830.

[0126] Along the axial direction of the drive rod 300, the drive rod 300 slides and slides to seal with the guide sleeve 830, while the guide sleeve 830 is fixedly fitted with the tapered plate 820. Along the circumferential direction of the drive rod 300, the drive rod 300 is fixedly fitted with the guide sleeve 830, while the guide sleeve 830 rotates and rotates to seal with the tapered plate 820.

[0127] The cap body 840 is coaxially arranged with the tube body 100, and the guide sleeve 830 passes through the cap body 840 and is fixedly connected to the cap body 840.

[0128] The cap body 840 is provided with a first extension arm 850 and a second extension arm 860.

[0129] The first extension arm 850 is fixedly connected to the cap body 840 and extends along the generatrix direction of the conical plate 820. The first extension arm 850 is in contact with the outer surface of the conical plate 820.

[0130] The second extension arm 860 is fixedly connected to the end of the first extension arm 850 away from the cap body 840. The second extension arm 860 extends radially along the annular plate 810 and is in contact with the surface of the annular plate 810 away from the first sealing plate 110.

[0131] Both the conical plate 820 and the annular plate 810 have filter holes.

[0132] With this design, the drive rod 300 will synchronously drive the cap body 840 to rotate during rotation. The cap body 840 can then drive the first extension arm 850 and the second extension arm 860 to move, so that the first extension arm 850 moves circumferentially along the outer surface of the conical plate 820 and the second extension arm 860 moves circumferentially along the surface of the annular plate 810.

[0133] In this way, when the conical plate 820 and the annular plate 810 filter impurities, the filtered impurities will remain on the surfaces of the conical plate 820 and the annular plate 810. Under the action of the first extension arm 850 and the second extension arm 860, the impurities will not adhere to the surfaces of the conical plate 820 and the annular plate 810, but will be pushed by the first extension arm 850 and the second extension arm 860, so that the impurities can move along the surfaces of the conical plate 820 and the annular plate 810, preventing the impurities from continuously depositing and solidifying on the surfaces of the conical plate 820 and the annular plate 810.

[0134] Even after prolonged operation, impurities are less likely to completely adhere to or deposit on the surfaces of the conical plate 820 and the annular plate 810, reducing the difficulty of cleaning the conical plate 820 and the annular plate 810 and allowing the filtered impurities to be easily cleaned.

[0135] Furthermore, since impurities can move along the surfaces of both the conical plate 820 and the annular plate 810, the filtered impurities will converge towards the annular plate 810 under the guidance of the conical plate 820. This effectively ensures the cleanliness of the conical plate 820, making it easier for the conical plate 820 to maintain a good filtration effect and making the impurities more concentrated, which is easier to clean.

[0136] Furthermore, the pipe body 100 is also provided with a slag discharge pipe 870, which is connected to the pipe body 100. The slag discharge pipe 870 is located on the side of the annular plate 810 away from the first sealing plate 110, and is disposed close to the surface of the annular plate 810. The slag discharge pipe 870 is provided with a control valve 880.

[0137] With this design, since the filtered impurities are concentrated at the annular plate 810, the control valve 880 of the slag discharge pipe 870 can be opened for a period of time after a period of operation (the specific opening time can be flexibly set according to actual needs). In this way, the impurities at the annular plate 810 can be directly discharged through the slag discharge pipe 870 by the impact force of the fluid in the pipe, thereby achieving self-cleaning of the filter plate.

[0138] It is understandable that the slag discharge pipe 870 can be connected to the waste collection container to avoid contamination.

[0139] To further improve the thoroughness of impurity discharge and reduce fluid loss within the pipeline, an encoder can be configured on the drive rod 300 to monitor its rotation. During impurity discharge, when the encoder detects that the second extension arm 860 has moved to the slag discharge pipe 870, it controls the control valve 880 of the slag discharge pipe 870 to open; when the second extension arm 860 moves away from the vicinity of the slag discharge pipe 870, it controls the control valve 880 to close. This allows for more efficient utilization of the pushing effect of the second extension arm 860 on the impurities, facilitating efficient and complete discharge.

[0140] This application also provides a municipal solid waste incinerator with heat recovery function, which includes: an incinerator body, heat exchange tubes and the aforementioned flow guide pipes.

[0141] The heat exchange tubes are located inside the flue gas passage of the incinerator body. The heat exchange tubes are straight tubes that run through the flue gas passage, with both the inlet and outlet ends extending outside the flue gas passage.

[0142] The inlet end of the heat exchange tube is connected to the heat exchange medium supply end, and the outlet end of the heat exchange tube is connected to the end of the tube body 100 of the guide pipe fitting away from the first sealing plate 110 (i.e., the inlet of the tube body 100). The opening 120 (outlet) of the tube body 100 is connected to the heat exchange medium recovery pipeline.

[0143] The heat exchange tube and the tube body 100 are coaxially arranged, and the inner diameters of the heat exchange tube and the tube body 100 are the same. The rotating wheel 200 is located inside the heat exchange tube.

[0144] The heat exchange medium is a liquid medium.

[0145] This design allows for the simultaneous transport of the heat exchange medium via the guide pipe fittings, while also monitoring the heat exchange tubes to detect any deformation caused by continuous operation in a high-temperature environment. Additionally, it cleans the inner wall of the heat exchange tubes to reduce scaling.

[0146] In summary, the flow guide pipe provided in this application embodiment can continuously monitor the structural integrity of the pipe without requiring shutdown for inspection, which contributes to the efficient operation of daily production. The municipal solid waste incinerator with heat recovery function provided in this application embodiment can continuously monitor the structural integrity of the heat exchange pipeline without requiring shutdown for inspection, which also contributes to the efficient operation of daily production.

[0147] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
