Description

Technical Field

[0001] This utility model relates to the field of treatment equipment, and in particular to a slurry circulation pump pipeline leakage treatment device for zero discharge of desulfurization wastewater. Background Technology

[0002] The slurry circulation pump pipeline leakage control device for zero discharge of desulfurization wastewater is a specialized piece of equipment or a combination of devices designed specifically for slurry leakage problems in slurry circulation pump pipelines within desulfurization wastewater treatment systems. When leakage occurs due to localized wear, corrosion, or cracks in the pipeline, quick repair clamps or welded repair structures can be used. The quick repair clamp typically consists of two semi-circular clamps, which are fastened to the leaking area of ​​the pipeline using bolts or hydraulic devices. The internal sealing gasket can immediately stop the leakage, buying time for subsequent permanent repairs. The welded repair structure requires first cleaning and beveling the leaking area, then using appropriate welding materials and processes to perform welding repairs and restore the integrity of the pipeline.

[0003] When pipeline leaks require emergency repairs, the process of installing and removing clamps becomes extremely complex and time-consuming. Traditional clamps may require a large number of bolts for tightening, and the bolts may be inaccessible. Maintenance personnel need to spend more time tightening or loosening these bolts, leading to delays in maintenance work, significantly reducing overall maintenance efficiency, and impacting system uptime. Traditional clamps rely on a single-layer seal. If this seal is damaged due to wear, aging, pressure shock, or chemical corrosion, causing slurry leakage, the sealing material may soften and deform, reducing its sealing effect. Furthermore, the slurry containing solid particles may scratch the sealing surface, creating leakage channels. Utility Model Content

[0004] The main purpose of this utility model is to provide a slurry circulation pump pipeline leakage control device for zero discharge of desulfurization wastewater. It can effectively solve the problems of delays in maintenance work, greatly reduce the overall maintenance efficiency, affect the normal operation time of the system, and cause slurry leakage. The sealing material may soften and deform, reducing the sealing effect. Under the flushing of slurry containing solid particles, the sealing surface may be scratched, creating leakage channels.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slurry circulation pump pipeline leakage control device for zero discharge of desulfurization wastewater, comprising a pipeline, an upper clamp at the top of the pipeline, a lower clamp at the bottom of the pipeline, first connecting plates fixedly connected to the front and rear sides of the upper clamp, sliders fixedly connected to the bottom of the two first connecting plates, and second connecting plates fixedly connected to the front and rear sides of the lower clamp, guide rail grooves opened inside the two second connecting plates, the bottoms of the two sliders slidably connected to the inside of the two guide rail grooves, first connecting blocks fixedly connected to the front and rear side walls of the upper and lower clamps, an outer shell provided inside each pair of upper and lower first connecting blocks, a retaining ring fixedly connected to the outer side of the top of each outer shell, an external threaded portion opened on the outer side of the top of each outer shell, a nut threaded to the outer side of each external threaded portion, and the bottom wall of each nut being provided with the top of each upper first connecting block.

[0006] Furthermore, each of the outer casings has a support plate rotatably connected to the left and right sides of its bottom end, and the top of every two support plates is located at the bottom of each lower first connecting block. Each outer casing has a connecting rod inside, a button is fixedly connected to the top of each connecting rod, and a fixing plate is fixedly connected to the bottom of each connecting rod.

[0007] Furthermore, each of the fixed plates has a second connecting block fixedly connected to the left and right sides of its upper sidewall, and a hinge frame is rotatably connected to the outer side of every two second connecting blocks. The outer sidewalls of every two hinge frames are fixedly connected to the inner sidewalls of every two support plates. A spring is fixedly connected to the bottom of the fixed plate, and the bottom end of the spring is fixedly connected to the inside of the outer shell.

[0008] Furthermore, semi-circular rings are fixedly connected to the outer sides of both the left and right ends of the upper and lower clamps, first sealing rings are fixedly connected to both the left and right ends of the interior of the lower clamp, and second sealing rings are fixedly connected to both the left and right sides of the interior of the lower clamp.

[0009] Furthermore, a threaded cylinder is connected to the top of the upper clamp, and a lead screw is threadedly connected inside the threaded cylinder. A handwheel is fixedly connected to the top of the lead screw.

[0010] Furthermore, a sleeve is rotatably connected to the outer side of the bottom end of the lead screw, and a soft sealing gasket is fixedly connected to the bottom of the sleeve. The bottom of the soft sealing gasket is set to correspond to the leakage hole of the pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, through its housing, nut, support plate, button, spring, and hinge frame, solves the problems that cause delays in maintenance work, greatly reduce overall maintenance efficiency, and affect the normal operation time of the system. By pressing the button, the connecting rod slides up and down inside the housing, and the fixing plate at the bottom of the connecting rod compresses the spring. When the button slides down, the second connecting blocks on the left and right sides of the upper side wall drive the hinge frame on the outer side to move. The other side of the hinge frame connects to the support plate, causing the support plate to unfold from the left and right sides of the bottom of the housing to support and lock the bottom wall of the first connecting block at the bottom. This effectively shortens maintenance time, reduces equipment downtime, and improves the operating efficiency of the entire desulfurization system.

[0013] 2. By using a first sealing ring, threaded cylinder, lead screw, and soft sealing gasket, the system effectively addresses issues such as slurry leakage, softening and deformation of the sealing material leading to reduced sealing performance, and scratches on the sealing surface caused by slurry containing solid particles, creating leakage channels. The lead screw rotates within the threaded cylinder. Based on the principle of threaded transmission, the lead screw achieves linear vertical displacement during rotation, moving smoothly and precisely downwards. The sleeve and bottom soft sealing gasket, rotatably connected to the outer side of the lead screw's bottom end, move downwards accordingly. The sleeve acts as a connection and guide, ensuring the soft sealing gasket is vertically aligned with the leak hole, preventing misalignment. This effectively reduces the frequency of equipment maintenance and replacement, lowers maintenance costs and reduces production losses due to downtime, thereby extending the equipment's lifespan.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1 - Figure 5 As shown: A slurry circulation pump pipeline leakage control device for zero discharge of desulfurization wastewater includes a pipeline 1. An upper clamp 2 is installed at the top of the pipeline 1, and a lower clamp 3 is installed at the bottom of the pipeline 1. By placing the lower clamp 3 at an appropriate position at the bottom of the pipeline 1, the lower clamp 3 is made to fit against the lower surface of the pipeline 1, and the position is initially stabilized to ensure smooth subsequent assembly. The upper clamp 2 is then lowered to the corresponding position at the top of the pipeline 1, and the upper clamp 2 and the lower clamp 3 together encircle the pipeline 1 to form a preliminary sealing situation.

[0026] The upper clamp 2 is fixedly connected to the front and rear sides with first connecting plates 4, and the bottom of the two first connecting plates 4 is fixedly connected to sliders 5. The lower clamp 3 is fixedly connected to the front and rear sides with second connecting plates 6. The interior of the two second connecting plates 6 is provided with guide rail grooves 7. The bottom of the two sliders 5 is slidably connected to the interior of the two guide rail grooves 7. The sliders 5 at the bottom of the first connecting plates 4 on the front and rear sides of the upper clamp 2 slide smoothly into the lower clamp 3. The guide rail grooves 7 and the sliders 5 are precisely matched, which not only guides the upper clamp 2 to return to its correct position, but also limits its excessive horizontal displacement, ensuring that the upper and lower clamps are tightly aligned with the pipeline, thus laying a solid foundation for subsequent sealing and reinforcement.

[0027] The upper clamp 2 and the lower clamp 3 are fixedly connected to the front and rear side walls with first connecting blocks 9. Each pair of upper and lower first connecting blocks 9 has an inner shell 10. A retaining ring 11 is fixedly connected to the outer top of each shell 10. An external thread 12 is formed on the outer top of each shell 10, and a nut 13 is threaded onto the outer side of each external thread 12. The bottom wall of each nut 13 is fitted with the top of each upper first connecting block 9. When the upper clamp 2 and the lower clamp 3 are fixed to the outside of the pipe 1, the first connecting blocks 9 of the upper clamp 2 and the lower clamp 3... The blocks 9 are arranged in pairs to insert the outer shell 10 into the slots of the two first connecting blocks 9. The retaining ring 11 at the top of the outer shell 10 abuts against the top surface of the upper first connecting block 9 to prevent the outer shell from descending excessively and to ensure accurate installation positioning. In addition, the nut 13 is screwed onto the external thread 12 of the outer shell 10. As the nut 13 is continuously tightened, the pressure between the bottom surface of the nut 13 and the top surface of the upper first connecting block 9 increases, causing the outer shell 10 to be firmly pressed down between the first connecting blocks 9, so as to achieve a tight clamping of the pipe 1 in the vertical direction by the upper and lower clamps and enhance the sealing effect.

[0028] like Figure 1 - Figure 5 As shown, each outer casing 10 has a support plate 14 rotatably connected to the left and right sides of its bottom end. The top of every two support plates 14 is located at the bottom of each lower first connecting block 9. Each outer casing 10 has a connecting rod 15 inside. A button 16 is fixedly connected to the top of each connecting rod 15. A fixing plate 17 is fixedly connected to the bottom of each connecting rod 15. Second connecting blocks 19 are fixedly connected to the left and right sides of the upper sidewall of each fixing plate 17. A hinge frame 20 is rotatably connected to the outer side of every two second connecting blocks 19. The outer sidewall of every two hinge frames 20 is fixedly connected to the inner sidewall of every two support plates 14. A spring 18 is fixedly connected to the bottom of the fixing plate 17. The bottom of the spring 18 is fixed... Connected inside the housing 10, the connecting rod 15 slides up and down inside the housing 10 by pressing the button 16, and the spring 18 is squeezed by the fixing plate 17 on the bottom of the connecting rod 15. When the button 16 slides down, the second connecting blocks 19 on the left and right sides of the upper side wall will drive the hinge frame 20 on the outer side to move. The other side of the hinge frame 20 is connected to the support plate 14, so that the support plate 14 can be opened from the left and right sides of the bottom end of the housing 10 to support and lock the bottom wall of the bottom first connecting block 9. With the cooperation of the nut 13, the upper side wall of the top first connecting block 9 slides to fix the upper clamp 2 and the lower clamp 3 on the outside of the pipe 1.

[0029] like Figure 1 - Figure 7As shown, semicircular rings 8 are fixedly connected to the outer sides of both the left and right ends of the upper clamp 2 and the lower clamp 3. First sealing rings 21 are fixedly connected to both the left and right ends of the interior of the lower clamp 3. Second sealing rings 22 are fixedly connected to both the left and right sides of the interior of the lower clamp 3. The first sealing ring 21 is made of rubber with strong corrosion resistance and good flexibility. It fits tightly against the outer wall of the pipe 1 with its own elasticity, filling the small unevenness and forming the first sealing line to prevent slurry penetration. The second sealing ring 22 is set inside to seal the middle of the pipe 1. After fitting, it prevents wastewater from flowing to the outside through the second sealing ring 22. The second sealing ring 22 and the first sealing ring 21 form a double seal on the outside of the pipe 1 to prevent wastewater from flowing out.

[0030] The top of the upper clamp 2 is connected to a threaded cylinder 23. The threaded cylinder 23 is internally threaded to a lead screw 24. A handwheel 25 is fixedly connected to the top of the lead screw 24. A sleeve 26 is rotatably connected to the bottom outer side of the lead screw 24. A soft sealing gasket 27 is fixedly connected to the bottom of the sleeve 26. The bottom of the soft sealing gasket 27 is set to correspond to the leak hole of the pipe 1. When the operator rotates the handwheel 25, the handwheel 25 drives the lead screw 24 to rotate inside the threaded cylinder 23. During the rotation, the lead screw 24 achieves vertical linear displacement and precise downward movement. The sleeve 26 and the bottom soft sealing gasket 27 rotatably connected to the bottom outer side of the lead screw 24 move downward accordingly. The sleeve 26 plays a connecting and guiding role, ensuring that the soft sealing gasket 27 is vertically aligned with the leak hole, avoiding misalignment, thereby sealing the leak hole of the pipe 1, preventing the leak hole from enlarging when the pipe 1 is transporting wastewater, and blocking the leak hole.

[0031] It should be noted that this utility model is a slurry circulation pump pipeline leakage control device for zero discharge of desulfurization wastewater.

[0032] When a leak occurs at pipe 1, place the lower clamp 3 at the appropriate position at the bottom of pipe 1, ensuring that the lower clamp 3 fits against the lower surface of pipe 1 to initially stabilize its position and ensure smooth subsequent assembly. Next, align the upper clamp 2 with the corresponding position at the top of pipe 1 and lower clamp 3. The upper clamp 2 and lower clamp 3 together encircle pipe 1, forming an initial seal. At this time, the slider 5 at the bottom of the first connecting plate 4 on both sides of the upper clamp 2 slides into the guide groove 7 inside the second connecting plate 6 of the lower clamp 3. The guide groove 7 and slider 5 fit precisely, guiding the upper clamp 2 to accurately return to its position and limiting its excessive horizontal displacement, ensuring that the upper and lower clamps are tightly aligned with the pipe, laying a solid foundation for subsequent sealing reinforcement.

[0033] When the upper clamp 2 and lower clamp 3 are fixed to the outside of the pipe 1, the first connecting blocks 9 of the upper and lower clamps are arranged in pairs to insert the outer shell 10 into the slots of the two first connecting blocks 9. The retaining ring 11 at the top of the outer shell 10 abuts against the top surface of the upper first connecting block 9 to prevent the outer shell from descending excessively and to ensure accurate installation positioning. Subsequently, the nut 13 is screwed onto the external thread 12 of the outer shell 10. As the nut 13 is continuously tightened, the pressure between the bottom surface of the nut 13 and the top surface of the upper first connecting block 9 increases, causing the outer shell 10 to be firmly pressed down between the first connecting blocks 9, thereby achieving a tight clamping of the upper and lower clamps on the pipe 1 in the vertical direction and enhancing the sealing effect.

[0034] During installation, pressing button 16 causes the connecting rod 15 to slide up and down inside the housing 10. The fixing plate 17 at the bottom of the connecting rod 15 compresses the spring 18. When button 16 slides downwards, the second connecting blocks 19 on the left and right sides of the upper sidewall move the hinge frame 20 on the outer side. The hinge frame 20 connects to the support plate 14 on the other side, causing the support plate 14 to unfold from the bottom left and right sides of the housing 10. This supports and locks the bottom wall of the first connecting block 9 at the bottom, and, in conjunction with nut 13, slides the upper sidewall of the first connecting block 9 at the top, fixing the upper clamp 2 and lower clamp 3 to the outside of the pipe 1. When disassembly is required, pressing button 16 again causes the connecting rod 15 and fixing plate 17 to push back the bottom spring 18, retracting the support plate 14 into the housing 10. This unlocks the fixation, allowing the upper clamp 2 and lower clamp 3 to be disassembled.

[0035] The first sealing ring 21 and the second sealing ring 22 inside the lower clamp 3 provide multiple sealing protection. The first sealing ring 21 is made of highly corrosion-resistant and flexible rubber. With its own elasticity, it fits tightly against the outer wall of the pipe 1, filling in minor unevenness and forming the first line of defense to prevent slurry penetration. The second sealing ring 22 is set inside to seal the middle of the pipe 1. After fitting, it prevents wastewater from flowing to the outside through the second sealing ring 22.

[0036] When a leak is found in pipe 1 requiring targeted treatment, the operator turns handwheel 25. Handwheel 25, acting as a power input component, drives screw 24 to rotate within threaded cylinder 23. Based on the principle of threaded transmission, screw 24 achieves linear vertical displacement during rotation, moving downwards smoothly and precisely. Sleeve 26 and bottom soft sealing gasket 27, rotatably connected to the outer side of screw 24, move downwards accordingly. Sleeve 26 serves as a connection and guide, ensuring that soft sealing gasket 27 is vertically aligned with the leak, preventing misalignment. The soft sealing gasket 27 is made of a highly elastic and corrosion-resistant material. After its bottom precisely covers the leak in pipe 1, as screw 24 applies continuous pressure, the gasket undergoes elastic deformation under pressure, tightly adhering to the pipe wall surrounding the leak. It adaptively fills the leak according to its shape, effectively sealing it.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
