Description

Technical Field

[0001] This utility model relates to the field of slurry pipeline technology, specifically to a slurry pipeline anti-crystallization and unblocking device. Background Technology

[0002] In mining production, slurry pipeline transportation is a crucial step. Slurry typically contains various minerals, additives, and water, and is transported from the mining site to processing facilities via pipelines to achieve efficient resource utilization. However, due to the chemical properties of the slurry's components and changes in physical conditions during transportation, crystallization can easily occur inside the pipeline. Crystallization not only reduces the pipeline's inner diameter, increasing transportation resistance and efficiency, but can also cause localized blockages, severely impacting the continuity and stability of production.

[0003] However, existing anti-crystallization and unblocking devices for slurry pipelines mostly use simple mechanical scraping or high-pressure water flushing. High-pressure water flushing is difficult to completely remove hardened crystals that have firmly adhered to the inner wall of the pipeline, and it is easy to leave residual crystals, which makes it difficult to maintain the unblocking effect. Mechanical scraping is inconvenient when cleaning the inner wall of some longer pipelines, such as the cleaning tools being difficult to penetrate. Therefore, this utility model provides an anti-crystallization and unblocking device for slurry pipelines. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a slurry pipeline anti-crystallization and unblocking device, which solves the problem that existing slurry pipeline anti-crystallization and unblocking devices mostly adopt simple mechanical scraping or high-pressure water flushing methods, both of which have significant defects in practical applications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slurry pipeline anti-crystallization and unblocking device, comprising a cleaning scraper ring, the cleaning scraper ring having a triangular cross-section, and scraper ring tensioning components on both sides of the cleaning scraper ring to assist in pulling the cleaning scraper ring to move against the inner wall of the slurry pipeline. The scraper ring tensioning components include:

[0006] The assembly unit is located on both sides of the cleaning scraper ring, including a vertical rod fixed to one side of the cleaning scraper ring, and a first connecting wire and a second connecting wire are fixed on both sides of the vertical rod. A first assembly frame is threaded through the first connecting wire, and a second assembly frame is threaded through the second connecting wire. A pull handle is fixed to the end of the first connecting wire.

[0007] A winding unit is disposed on the side of the second assembly frame and is used to connect and wind the second connecting wire;

[0008] The positioning unit is located outside the assembly unit and is used to limit the distance between the first assembly frame and the second assembly frame.

[0009] Preferably, the winding unit includes two sets of base rods fixed to one side of the second assembly frame, with a rotating shaft rotatably mounted on the two sets of base rods, a winding wheel fixed in the middle section of the rotating shaft, and a handle fixed at the upper end of the rotating shaft.

[0010] Preferably, the winding wheel is provided with a ring buckle, and the end of the second connecting wire is provided with a hook that engages with the ring buckle.

[0011] Preferably, the positioning unit includes a base block fixed to the upper and lower parts of the first assembly frame, and one end of the base block is connected to a third connecting wire, and the upper and lower parts of the second assembly frame are fixed with double-hole blocks.

[0012] Preferably, an L-shaped block is fixed to the side of the double-hole block, and a threaded rod is threadedly connected to the side of the L-shaped block. An extrusion plate is fixed to the side of the threaded rod facing the double-hole block, so that the third connecting wire is folded through the double holes provided on the double-hole block and is extruded and fixed by the extrusion plate.

[0013] Preferably, the first and second assembly frames are cross-shaped, and the edges of the first and second assembly frames are provided with a number of U-shaped blocks that can engage with the edges of the slurry pipes.

[0014] This utility model provides a device for preventing crystallization and clearing blockages in slurry pipelines. Compared with the prior art, it has the following advantages:

[0015] 1. This slurry pipeline anti-crystallization and unblocking device can be flexibly assembled onto slurry pipelines of any length through the assembly unit and positioning unit in the scraper ring stretching assembly. Specifically, the device is initially positioned by the U-shaped blocks at the edges of the first and second assembly frames engaging with the edges of the slurry pipeline. The cleaning scraper ring is then moved inside the slurry pipeline by the winding unit. The triangular cross-section of the cleaning scraper ring is used to scrape and clean the crystals on the inner wall of the slurry pipeline, effectively improving the device's adaptability to various pipeline environments and its crystal cleaning effect.

[0016] 2. The slurry pipeline anti-crystallization and unblocking device features U-shaped blocks at the edges of the first and second assembly frames, which can engage with the edges of the slurry pipeline to achieve initial positioning of the device. The installation process is convenient and quick. At the same time, the positioning unit further stabilizes the device's position in the pipeline by fixing the third connecting wire with an extrusion plate, ensuring that the device will not easily shake or shift during the cleaning operation, thus improving the stability of the device's operation and ensuring the continuous and efficient execution of the anti-crystallization and unblocking operation.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a device for preventing crystallization and clearing slurry pipelines, specifically including the following embodiments:

[0024] Example 1: A slurry pipeline anti-crystallization and unblocking device includes a cleaning scraper ring 1 with a triangular cross-section. Scraper ring tensioning components 2 are provided on both sides of the cleaning scraper ring 1 to assist in pulling the cleaning scraper ring 1 to move against the inner wall of the slurry pipeline. The scraper ring tensioning components 2 include: an assembly unit 21 disposed on both sides of the cleaning scraper ring 1, including a vertical rod 211 fixed to one side of the cleaning scraper ring 1. A first connecting wire 212 and a second connecting wire 214 are fixed to both sides of the vertical rod 211. A first assembly frame 213 is threaded through the first connecting wire 212, and a second assembly frame 215 is threaded through the second connecting wire 214. A handle 216 is fixed to the end of the wire 212; a winding unit 22 is set on the side of the second assembly frame 215 and is used to connect and wind the second connecting wire 214; a positioning unit 23 is set outside the assembly unit 21 and is used to limit the distance between the first assembly frame 213 and the second assembly frame 215; the U-shaped blocks at the edges of the first assembly frame 213 and the second assembly frame 215 engage with the edge of the slurry pipe to initially position the device, and the winding unit 22 pulls the cleaning scraper ring 1 to move inside the slurry pipe, using the triangular cross-section of the cleaning scraper ring 1 to scrape and clean the crystals on the inner wall of the slurry pipe.

[0025] Example 2: The main difference between this example and the first technical solution is that: a slurry pipeline anti-crystallization and unblocking device, the winding unit 22 includes two sets of base rods 221 fixed to one side of the second assembly frame 215, a rotating shaft 222 is rotatably mounted on the two sets of base rods 221, a winding wheel 223 is fixed in the middle of the rotating shaft 222, and a handle 224 is fixed at the upper end of the rotating shaft 222.

The positioning unit 23 includes a base block 231 fixed to the upper and lower parts of the first assembly frame 213, and a third connecting wire 232 is connected to one end of the base block 231. A double-hole block 233 is fixed to the upper and lower parts of the second assembly frame 215. An L-shaped block 234 is fixed to the side of the double-hole block 233. A threaded screw rod 235 is threaded to the side of the L-shaped block 234. An extrusion plate 236 is fixed to the side of the threaded screw rod 235 facing the double-hole block 233, so that... The third connecting wire 232 is folded through the double holes provided on the double-hole block 233 and pressed and fixed by the extrusion plate 236. The first assembly frame 213 and the second assembly frame 215 are specifically cross-shaped, and several sets of U-shaped blocks that can engage with the edge of the slurry pipe are provided at the edge of the first assembly frame 213 and the second assembly frame 215. By rotating the threaded screw rod 235, the extrusion plate 236 is released from the pressure on the third connecting wire 232. After moving the second assembly frame 215 to a suitable position, the threaded screw rod 235 is rotated again to make the extrusion plate 236 press the third connecting wire 232 again, thus fixing the distance between the first assembly frame 213 and the second assembly frame 215. Finally, by rotating the handle 224, the handle 224 drives the rotating shaft 222 to rotate, and the rotating shaft 222 drives the winding wheel 223 to rotate. The winding wheel 223 winds or loosens the second connecting wire 214, thereby pushing the cleaning scraper ring 1 to move inside the slurry pipe.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] During operation, the cleaning scraper ring 1 is first placed inside the slurry pipe. At this time, the scraper ring tensioning assembly 2 is located on both sides of the cleaning scraper ring 1. The first connecting wire 212 passes through the first mounting frame 213, and the second connecting wire 214 passes through the second mounting frame 215. The two sets of base rods 221 of the winding unit 22 are fixed to one side of the second mounting frame 215. The rotating shaft 222 is rotatably mounted on the base rods 221. The winding wheel 223 is fixed in the middle section of the rotating shaft 222, and the handle 224 is fixed at the upper end of the rotating shaft 222. The hook at the end of the second connecting wire 214... The hook is attached to the ring of the winding wheel 223; the base block 231 of the positioning unit 23 is fixed to the upper and lower parts of the first assembly frame 213, one end of the third connecting wire 232 is connected to the base block 231, the double-hole block 233 is fixed to the upper and lower parts of the second assembly frame 215, the L-shaped block 234 is fixed to the side of the double-hole block 233, the threaded rod 235 is threadedly connected to the side of the L-shaped block 234, the extrusion plate 236 is fixed to the side of the threaded rod 235 facing the double-hole block 233, and the third connecting wire 232 is folded and passes through the double-hole block 233. The hole is pressed and fixed by the extrusion plate 236. At the same time, the U-shaped blocks at the edges of the first assembly frame 213 and the second assembly frame 215 engage with the edges of the slurry pipe, performing initial positioning of the device. During the adjustment process, the positioning unit 23 limits the distance between the first assembly frame 213 and the second assembly frame 215. By rotating the threaded screw rod 235, the extrusion plate 236 is released from pressing the third connecting wire 232. After moving the second assembly frame 215 to the appropriate position, the threaded screw rod 235 is rotated again to release the extrusion plate 236 from pressing the third connecting wire 232. 36. The third connecting wire 232 is re-pressed to fix the distance between the first assembly frame 213 and the second assembly frame 215; finally, by rotating the handle 224, the handle 224 drives the rotating shaft 222 to rotate, the rotating shaft 222 drives the winding wheel 223 to rotate, the winding wheel 223 winds or loosens the second connecting wire 214, and then pushes the cleaning scraper ring 1 to move inside the slurry pipe. Using the triangular cross-section of the cleaning scraper ring 1, the crystals on the inner wall of the slurry pipe are scraped and cleaned, thereby realizing the anti-crystallization and unblocking operation of the slurry pipe.
