Description

Technical Field

[0001] This invention belongs to the field of cement pipe production technology, specifically a steam curing device for cement pipe maintenance. Background Technology

[0002] Cement pipes, as part of urban infrastructure, serve as drainage pipes for sewage discharge and flood control. They can also be used for water supply in factories and mines, and for farmland wells. After manufacturing, cement pipes need to be placed in a steam curing tank and steam is introduced into the tank for curing, typically for 2.5-3.5 hours. After steam curing, the cement pipes solidify and take shape.

[0003] Currently, when steam curing cement pipes, the pipes are typically placed directly in a curing tank. The pipes' position within the tank remains fixed, and the steam outlet is usually also fixed. Due to limitations in steam density and flow path, this results in uneven contact between different parts of the pipe and the steam, affecting the curing quality. During curing, the steam condenses upon cooling and needs to be drained promptly. However, existing steam curing devices for cement pipes have drainage pipes directly connected to the outside environment, potentially causing steam leakage and increasing energy consumption. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a steam curing device for cement pipe maintenance, so as to at least partially solve the problems mentioned in the background art.

[0016] Furthermore, the first steam plate, the second steam plate, the support plate, the mounting plate in the steam curing tank, and the two sets of rotating shafts are all hollow structures. The rotating shafts in the steam curing tank are connected to a steam supply pipe, which is rotatably connected to the set of rotating shafts. The steam supply pipe is connected to a steam generator. A lower steam passage is provided on the side wall of the steam curing tank with a groove. A connecting plate is provided on the bottom wall of the steam curing tank, and a steam inlet channel is provided on the connecting plate. The lower steam passage is connected to the mounting plate in the steam curing tank through the steam inlet channel. An upper steam passage is provided in the protruding plate of the steam curing cover. The upper steam passage is configured to match the size and position of the lower steam passage. A steam inlet groove is provided on the part of the rotating shaft located in the upper steam passage.

[0017] Furthermore, one of the grooves in the steam curing tank and the protrusions on the steam curing cover is provided with a sealing groove, and the other is provided with a sealing protrusion. The sealing protrusion is used to embed into the sealing groove to seal the sealing groove.

[0018] Furthermore, the drainage tank includes a collection section and a drainage section. The collection section is located above the drainage section, and the width of the drainage section is greater than that of the collection section. A drainage pipe is provided through the side wall of the steam curing tank. The drainage pipe is connected to the drainage section and is connected to a water collection tank.

[0023] The beneficial effects achieved by the present invention using the above structure are as follows:

[0024] 1. By rotating the first and second steam plates inside the steam curing tank and steam curing cover, the relative position of the steam hole and the cement pipe is adjusted, so that steam can contact the cement pipe from multiple angles and directions from above and below, avoiding the problem of uneven steam curing caused by the traditional fixed steam outlet, and significantly improving the steam curing quality of cement pipe.

[0025] 2. By setting up a sliding and lifting sealing plate in the drainage tank, the balance between the spring force of the sealing component and the gravity of the liquid is utilized to achieve the dual functions of automatic discharge of liquefied liquid and steam sealing. At the same time, the cooperation between the sealing groove and the sealing protrusion between the steam curing tank and the steam curing cover further enhances the overall sealing performance, effectively prevents steam leakage, reduces steam energy consumption, and saves production costs.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0043] See Figures 1-4 , Figure 9 , Figure 12 and Figure 13 This embodiment provides a steam curing device for cement pipe maintenance, including a steam curing tank 1, a steam curing cover 2, a support 9, a first steam plate 4, a second steam plate 5, a drain trough 6, and a sealing plate 7; the steam curing cover 2 and the steam curing tank 1 are detachably installed, and a set of rotating shafts 3 are respectively installed inside the steam curing tank 1 and the steam curing cover 2; the support 9 is provided on the bottom wall of the steam curing tank 1, and a pipe placement groove 10 for placing cement pipes is provided on it; the first steam plate 4 is rotatably installed in the steam curing tank 1 through the rotating shafts 3 to adjust the relative position of the first steam plate 4 and the cement pipe; the second steam plate 5 is rotatably installed in the steam curing cover 2 through the rotating shafts 3 to adjust the relative position of the second steam plate 5 and the cement pipe; A drain trough 6 is located on the bottom wall of the steam curing tank 1 and is used to drain the liquefied liquid in the steam curing tank 1. A sealing plate 7 is configured to slide up and down within the drain trough 6 to adjust the opening and closing state of the drain trough 6. When the drain trough 6 is open, the liquefied liquid in the steam curing tank 1 is drained. When the sealing plate 7 seals the drain trough 6, the steam curing tank 1 is not connected to the outside world, thus preventing steam leakage and achieving the purpose of energy saving in steam curing. The first steam plate 4 and the second steam plate 5 are both provided with steam holes 8 on the side facing the cement pipe. When the first steam plate 4 and the second steam plate 5 rotate, the relative position of the steam holes 8 and the cement pipe is adjusted to improve the uniformity of steam curing of the cement pipe.

[0044] During operation, the cement pipe is placed in the steam curing tank 1, with the first steam plate 4 positioned below the cement pipe and the second steam plate 5 positioned above it. The first and second rotating shafts 3 drive the first steam plate 4 and the second steam plate 5 to rotate, adjusting the relative position of the steam hole 8 with the cement pipe to improve the uniformity of steam curing. During steam curing, the liquefied liquid concentrates in the drain trough 6. When the sealing plate 7 moves down to release the seal on the drain trough 6, the liquefied liquid is discharged through the drain trough 6.

[0045] Specifically, see Figures 7-11In this embodiment, the support 9 is a hollow structure, and the tube placement groove 10 is provided with steam curing holes. The support 9 is provided with a swing groove 11. During steam curing, the cement pipe is placed in the tube placement groove 10, and through the cooperation between the hollow structure of the support 9 and the steam curing holes, the steam in the steam curing tank 1 enters the steam curing holes from the swing groove 11 to steam curing the cement pipe placed on the support 9. The first steam plate 4 includes multiple steam parts 12 and connecting parts 13. The steam holes 8 are located on the side of the steam parts 12 facing the cement pipe. The steam parts 12 at both ends are respectively connected to the corresponding rotating shafts 3 through a set of support plates 14. Two adjacent steam parts 12 are connected through the connecting parts 13. The connecting parts 13 are slidably disposed in the swing groove 11 to adapt to the rotation of the rotating shaft 3.

[0046] During operation, the rotating shaft 3 in the steam curing tank 1 drives the steam section 12 to rotate through the support plate 14. Multiple steam sections 12 rotate synchronously through the connection of the connecting part 13. The rotation of the steam section 12 realizes the adjustment of the relative position between the steam hole 8 and the cement pipe. During the above rotation process, the connecting part 13 swings in the swing groove 11.

[0047] Specifically, see Figure 4 , Figure 5 and Figure 7 In this embodiment, both the steam curing tank 1 and the steam curing cover 2 are provided with protruding plates 15 and grooves 16. The protruding plates 15 and grooves 16 of the steam curing tank 1 correspond to the grooves 16 and protruding plates 15 of the steam curing cover 2, respectively. Mounting plates 17 are fixedly provided inside both the steam curing tank 1 and the steam curing cover 2. The rotating shaft 3 is rotatably located between the protruding plates 15 and the mounting plates 17. The mounting plates 17 inside the steam curing tank 1 are close to the protruding plates 15 on the steam curing cover 2, and the mounting plates 17 inside the steam curing cover 2 are close to the protruding plates 15 on the cover of the steam curing tank 1.

[0048] In specific implementation, the protruding plate 15 and the mounting plate 17 are set so that the rotating shaft 3 inside the steam curing tank 1 and the steam curing cover 2 are coaxially arranged, and the axis of the rotating shaft 3 is the same as the axis of the cement pipe. When the rotating shaft 3 drives the first steam plate 4 and the second steam plate 5 to rotate, the first steam plate 4 and the second steam plate 5 only perform circumferential rotation relative to the cement pipe, and the relative distance between the first steam plate 4 and the second steam plate 5 and the cement pipe remains unchanged; and when the two rotate, their rotational movements do not interfere with each other.

[0049] Specifically, see Figures 1-3 In this embodiment, both the steam curing tank 1 and the steam curing cover 2 are equipped with a rotating motor 18. The output end of the rotating motor 18 is fixedly equipped with a driving gear 19, and the rotating shaft 3 on the protruding plate 15 is fixedly equipped with a driven gear 20. The driven gear 20 meshes with the driving gear 19.

[0050] During operation, the rotating motor 18 drives the drive gear 19 to rotate, and the drive gear 19 and the driven gear 20 mesh to drive the rotating shaft 3 to rotate. The rotating shaft 3 drives the corresponding first steam plate 4 and second steam plate 5.

[0051] It should be noted that in this embodiment, the rotating motor 18 rotates intermittently in both forward and reverse directions, thereby driving the first steam plate 4 and the second steam plate 5 to oscillate in a fan shape. During the fan-shaped oscillation of the first steam plate 4 and the second steam plate 5, the relative position of the steam hole 8 and the cement pipe is adjusted. In this embodiment, the rotating motors 18 on the steam curing tank 1 and the steam curing cover 2 rotate in opposite directions to avoid interference between the fan-shaped oscillations of the first steam plate 4 and the second steam plate 5.

[0052] Specifically, see Figure 4 and Figure 6 In this embodiment, the first steam plate 4, the second steam plate 5, the support plate 14, the mounting plate 17 in the steam curing tank 1, and the two sets of rotating shafts 3 are all hollow structures. The rotating shafts 3 in the steam curing tank 1 are connected to a steam supply pipe 21, which is rotatably connected to the set of rotating shafts 3. The steam supply pipe 21 is connected to a steam generator. The side wall of the steam curing tank 1 with a groove 16 has a lower steam passage 22. The bottom wall of the steam curing tank 1 has a connecting plate 23, and the connecting plate 23 has a steam inlet channel 24. The lower steam passage 22 is connected to the mounting plate 17 in the steam curing tank 1 through the steam inlet channel 24. The protruding plate 15 of the steam curing cover 2 has an upper steam passage 25, which is configured to match the size and position of the lower steam passage 22. The part of the rotating shaft 3 located in the upper steam passage 25 has a steam inlet 26.

[0053] It should be noted that in this embodiment, only the part of the rotating shaft 3 located inside the steam curing cover 2 that is connected to the upper steam passage 25 is hollow. The part of the rotating shaft 3 that extends outside the steam curing cover 2 and is equipped with the driven gear 20 needs to be solid to prevent steam from leaking along the rotating shaft 3.

[0054] During operation, the steam generated by the steam generator is transported along the steam supply pipe 21 to the rotating shaft 3 in the steam curing tank 1. The rotating shaft 3 is then transported to the first steam plate 4 via the support plate 14. Part of the steam is discharged through the steam holes 8 of the first steam plate 4, and steam curing the cement pipe from below. Another part of the steam is transported through the first steam plate 4 and the connected rotating shaft 3 to the support plate 14. The support plate 14 is then transported through the steam inlet channel 24 to the lower steam channel 22 and the upper steam channel 25. The steam in the upper steam channel 25 enters the rotating shaft 3 of the steam curing cover 2 through the steam inlet channel 26, and is then transported to the second steam plate 5 via the support plate 14 connected to the rotating shaft 3. The steam is discharged through the steam holes 8 of the second steam plate 5, and steam curing the cement pipe from below. Furthermore, during the steam curing process described above, the rotation of the rotating motor 18 drives the corresponding first steam plate 4 and second steam plate 5 to rotate via the rotating shaft 3, thereby adjusting the relative position of the steam hole 8 and the cement pipe and improving the uniformity of steam curing of the cement pipe by the steam discharged from the steam hole 8.

[0055] Specifically, see Figure 5 and Figure 7 In this embodiment, a sealing groove 27 is provided on one of the groove 16 of the steam curing tank 1 and the protrusion 15 of the steam curing cover 2, and a sealing protrusion 28 is provided on the other. The sealing protrusion 28 is used to embed into the sealing groove 27 to seal the sealing groove 27.

[0056] During operation, the sealing groove 27 and the sealing protrusion 28 cooperate to ensure that when the steam curing cover 2 is placed on the steam curing tank 1, the sealing protrusion 28 is precisely embedded in the sealing groove 27. The cooperation between the sealing protrusion 28 and the sealing groove 27 improves the sealing tightness between the steam curing tank 1 and the steam curing cover 2, preventing steam leakage and waste of steam energy.

[0057] Specifically, see Figure 4 , Figures 9-11 In this embodiment, the drainage tank 6 includes a collection section 29 and a drainage section 30. The collection section 29 is located above the drainage section 30. The width of the drainage section 30 is greater than that of the collection section 29. A drainage pipe 31 is provided through the side wall of the steaming tank 1. The drainage pipe 31 is connected to the drainage section 30. The drainage pipe 31 is connected to a water collection tank. A sealing assembly is provided on the bottom wall of the drainage section 30. A sealing plate 7 is connected to the sealing assembly. The sealing plate 7 is slidably disposed in the drainage section 30 to control the sealing state of the collection section 29.

[0058] Specifically, see Figure 9 and Figure 11In this embodiment, the sealing assembly includes a slide cylinder 32, a slide rod 33, and a sealing spring 34. The slide cylinder 32 is fixedly disposed on the bottom wall of the drainage section 30. The slide rod 33 is slidably disposed inside the slide cylinder 32 and is connected to the sealing plate 7. The sealing spring 34 is sleeved on the outside of the slide cylinder 32 and the slide rod 33. The two ends of the sealing spring 34 are respectively connected to the bottom wall of the drainage section 30 and the sealing plate 7.

[0059] During operation, the liquid generated by liquefaction during steam curing is concentrated in the liquid collection section 29. When the liquid accumulates to a certain amount, the gravity of the liquid presses down on the sealing plate 7, compressing the sealing spring 34. The liquefied liquid is discharged through the drain section 30 and the drain pipe 31. After the liquid is discharged, the sealing plate 7 moves upward and resets under the action of the sealing spring 34, continuing to seal the liquid collection section 29 to prevent steam leakage.

[0060] Specifically, see Figure 9 and Figure 10 In this embodiment, an inclined liquid inlet trough 35 is provided on the bottom wall of the steam curing tank 1. One end of the liquid inlet trough 35 is connected to the liquid outlet trough 6. The height of the end of the liquid inlet trough 35 connected to the liquid outlet trough 6 is lower than that of the other end. The liquid inlet trough 35 can be used to guide the liquefied liquid in the steam curing tank 1 to the liquid outlet trough 6.

[0061] Specifically, see Figure 1 , Figure 3 and Figure 4 In this embodiment, a steam curing device for cement pipe maintenance also includes a support 36, on which a lifting cylinder 37 is provided. The steam curing cover 2 is connected to the free end of the lifting cylinder 37. The steam curing cover 2 is lifted and lowered by the lifting cylinder 37 to adjust the steam curing position of the steam curing cover 2 and the steam curing tank 1. The lower end of the support 36 is provided with a moving wheel 38. The moving wheel 38 can move the support 36, and the support 36 moves the steam curing cover 2 away from the steam curing tank 1 to improve the convenience of feeding cement pipes.

[0062] It is important to know that, in order to improve the positioning accuracy and stability of the relative positions of the steam curing cover 2 and the steam curing tank 1, the bracket 36 and the steam curing tank 1 are equipped with corresponding positioning structures. For example, a positioning groove 39 is provided on the side wall of the steam curing tank 1, and a positioning cylinder 40 is provided on the bracket 36. A positioning column 41 is provided at the free end of the positioning cylinder 40. Under the extension action of the positioning cylinder 40, the positioning column 41 is driven to embed into the positioning groove 39, thereby fixing the position of the bracket 36 and ensuring the installation and steam curing stability of the steam curing cover 2 and the steam curing tank 1.

[0063] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, material, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, material, or apparatus.
