Description

Technical Field

[0001] This utility model relates to the field of pipeline cleaning, and in particular to a quick-release pipeline cleaning component with anti-clogging at the bottom of a pre-pressurization tank. Background Technology

[0002] In industrial sectors such as chemical processing, food processing, and water treatment, pre-pressure tanks are crucial equipment for material storage, pressure regulation, and transportation. The stable operation of their bottom piping systems directly impacts the efficiency and safety of the entire production process. During long-term storage or transportation within the pre-pressure tank, materials are prone to blockages in the bottom piping due to sedimentation, crystallization, or impurity accumulation. This not only reduces material transport efficiency but also causes equipment malfunctions such as abnormal pressure and localized wear. Therefore, a dedicated pipe cleaning assembly must be installed at the bottom of the pre-pressure tank to address blockage issues.

[0003] In existing technologies, mechanical structures for preventing blockages and cleaning the bottom pipes of pre-pressure tanks typically combine fixed filter devices with manual unblocking mechanisms. The technical principle involves installing a fixed filter screen inside the pipe to intercept large particles or sediments in the material, preventing them from entering the downstream pipes and causing blockages. When impurities accumulate on the filter screen to a certain extent, manual cleaning is required using tools such as a cleaning rod or high-pressure water gun, inserted through a pre-reserved inspection port in the pipe, to clean the filter screen and the inner wall of the pipe. Some designs also include an observation window on the outside of the pipe, allowing operators to observe the internal blockage situation and decide whether to stop the machine for cleaning.

[0004] However, existing fixed filter screens are typically connected to pipes via bolts, flanges, and other fasteners. When cleaning or maintaining the filter screen is required, operators must first shut down the equipment and then use wrenches or other tools to remove multiple bolts or flanges before the filter screen can be removed from the pipe. After cleaning, the fasteners must be reinstalled and tightened. The entire process is cumbersome and time-consuming, significantly extending equipment downtime and negatively impacting production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-release cleaning pipe assembly for the bottom of a pre-pressure tank to prevent blockage, aiming to improve the problem of time-consuming cleaning and maintenance and prolonged equipment downtime caused by the inability to quickly disassemble the filter screen.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pre-pressurization tank bottom anti-clogging quick-release cleaning pipe assembly, comprising a hollow block, connecting components on both sides of the hollow block, a filter screen slidably connected inside the hollow block, a baffle fixedly connected to the side wall of the filter screen, a locking block fixedly connected to the side wall of the baffle, a handle fixedly connected to the side wall of the baffle, the side wall of the baffle slidably connected to the side wall of the hollow block, and a buckle assembly provided on the side wall of the hollow block;

[0007] The buckle assembly includes a connecting plate, the side wall of which is fixedly connected to the side wall of the hollow block. A rotating plate is rotatably connected to the side wall of the connecting plate. A protective component is provided on the outer wall of the rotating plate. A second rotating shaft is fixedly connected inside the rotating plate. A retaining ring is slidably connected inside the second rotating shaft. A nut is threadedly connected to the outer wall of the retaining ring. The side wall of the nut is slidably connected to the outer wall of the second rotating shaft. The side wall of the retaining ring is slidably connected to the side wall of the buckle block.

[0008] As a further description of the above technical solution:

[0009] The protective component includes an anti-slip strip, the outer wall of which is fixedly connected to the outer wall of the rotating plate.

[0010] As a further description of the above technical solution:

[0011] The connecting assembly includes a second flange, the bottom of which is fixedly connected to the top of the hollow block, and the top of which is slidably connected to a first flange.

[0012] As a further description of the above technical solution:

[0013] The outer walls of the first flange and the second flange are rotatably connected to a first clamping plate and a second clamping plate, and the first clamping plate and the second clamping plate are rotatably connected to a first rotating shaft. The first clamping plate and the second clamping plate are connected through the first rotating shaft.

[0014] As a further description of the above technical solution:

[0015] A connecting frame is fixedly connected to the side wall of the first clamping plate, and a screw is rotatably connected inside the connecting frame. A handle is fixedly connected to one end of the screw.

[0016] As a further description of the above technical solution:

[0017] The screw has a threaded connection to a movable block on its outer wall, and a slider is fixedly connected to the side wall of the movable block. The side wall of the slider is slidably connected inside the connecting frame.

[0018] As a further description of the above technical solution:

[0019] The second clamping plate has a limiting block fixedly connected to its side wall, the limiting block side wall is rotatably connected to the inner wall of the connecting frame, and the limiting block side wall is rotatably connected to the side wall of the moving block.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the anti-slip strip is moved to drive the rotating plate to rotate on the side wall of the connecting plate, which in turn drives the internal second rotating shaft and the retaining ring to rotate, causing the outer wall of the retaining ring to disengage from the side wall of the retaining block; then the handle is pulled to drive the baffle and the slider to slide on the inner wall of the hollow block, realizing the quick disassembly of the filter screen. This solves the problem of time-consuming cleaning and maintenance and prolonged equipment downtime caused by the inability to quickly disassemble the filter screen, and improves the practicality of the anti-clogging quick-disassembly cleaning pipe assembly.

[0022] 2. Move the first and second clamping plates so that their inner walls are locked against the outer walls of the first and second flanges. The limiting block on the side wall of the second clamping plate abuts against the inner wall of the connecting frame on the side wall of the first clamping plate. Turn the handle to drive the screw to rotate on the inner wall of the connecting frame. The screw drives the outer wall moving block to slide in the connecting frame, so that the side wall of the moving block abuts against the limiting block, locking the two clamping plates and realizing the quick connection of the flanges. This solves the problem of traditional bolted connections requiring the tightening and loosening of bolts one by one, which is time-consuming and labor-intensive and affects maintenance efficiency. It also enhances the convenience of anti-clogging quick-disassembly cleaning of pipe components. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a quick-release cleaning pipeline assembly for the bottom of a pre-pressurization tank, comprising a hollow block 3, with connecting components on both sides of the hollow block 3. A filter screen 22 is slidably connected inside the hollow block 3. The filter screen 22 is used to intercept large particles or sediments in the material in the pipeline at the bottom of the pre-pressurization tank, thereby preventing impurities from entering the downstream pipeline and causing blockage, ensuring the stability of pipeline transportation. A baffle 7 is fixedly connected to the side wall of the filter screen 22. The baffle 7 slides synchronously with the filter screen 22. The baffle 7 is connected to the buckle assembly through a locking block 9, achieving the effect of fixing the position of the filter screen 22 and realizing quick pull-out and disassembly, facilitating regular cleaning of impurities. The side wall of the baffle 7 is fixed. A latch 9 is connected to the side wall of the baffle 7, and a handle 8 is fixedly connected to the side wall of the baffle 7. The handle 8 is fixedly connected to the side wall of the baffle 7 and its function is to provide a force point so that the operator can pull the baffle 7 and the filter screen 22 to pull out or push the hollow block 3. This is common knowledge and will not be elaborated on here. The side wall of the baffle 7 is slidably connected to the side wall of the hollow block 3. The side wall of the hollow block 3 is provided with a latch assembly. The latch assembly consists of a connecting plate 10, a rotating plate 11, a second rotating shaft 13, a retaining ring 14 and a nut 15. By rotating the rotating plate 11, the retaining ring 14 is driven to lock or disengage from the latch 9. With the tightening of the nut 15, the baffle 7 is quickly locked and unlocked, which greatly shortens the cleaning and maintenance time.

[0032] The buckle assembly includes a connecting plate 10, the side wall of which is fixedly connected to the side wall of the hollow block 3. A rotating plate 11 is rotatably connected to the side wall of the connecting plate 10. A protective component is provided on the outer wall of the rotating plate 11. A second rotating shaft 13 is fixedly connected inside the rotating plate 11. A retaining ring 14 is slidably connected inside the second rotating shaft 13. A nut 15 is threadedly connected to the outer wall of the retaining ring 14. The side wall of the nut 15 is slidably connected to the outer wall of the second rotating shaft 13. The side wall of the retaining ring 14 is slidably connected to the side wall of the buckle block 9. The protective component includes an anti-slip strip 12, which is fixedly connected to the outer wall of the rotating plate 11. Its function is to increase the friction when the operator moves the rotating plate 11, prevent slippage, and improve the ease of operation. This is common knowledge and will not be elaborated further here. The outer wall of the anti-slip strip 12 is fixedly connected to the outer wall of the rotating plate 11.

[0033] Reference Figure 4 and Figure 5 The connecting assembly consists of a first flange 1, a second flange 2, a first clamping plate 4, a second clamping plate 5, a first rotating shaft 6, a connecting frame 16, a screw 17, a handle 18, a moving block 19, a limiting block 20, and a slider 21. Initial positioning is achieved through the docking of the first flange 1 and the second flange 2. Combined with the clamping action of the first clamping plate 4 and the second clamping plate 5, the two flanges are quickly fixed without the need to individually tighten or loosen bolts, improving installation and disassembly efficiency. The connecting assembly includes the second flange 2, whose bottom is fixedly connected to the top of the hollow block 3. The first flange 1 is slidably connected to the top of the second flange 2. The first clamping plate 4 and the second clamping plate 5 are rotatably connected to the outer walls of both the first flange 1 and the second flange 2. A first rotating shaft 6 is rotatably connected inside the first clamping plate 4 and the second clamping plate 5. The first clamping plate 4 and the second clamping plate 5 are connected via the first rotating shaft 6. The first clamping plate 4 is fixedly connected to a connecting frame 16 on its side wall. A screw 17 is rotatably connected inside the connecting frame 16. The screw 17 engages with the moving block 19 for threaded transmission. The operator turns the handle 18 to drive the screw 17 to rotate, causing the moving block 19 to slide along the inner wall of the connecting frame 16 and tightly press against the limiting block 20. The slider 21 prevents the moving block 19 from rotating synchronously with the screw 17, thus achieving the effect of ensuring the sealing of the flange connection through clamping force and ensuring the stable operation of the material conveying at the bottom of the pre-pressure tank. A handle 18 is fixedly connected to one end of the screw 17. The moving block 19 is threadedly connected to the outer wall of the screw 17. A slider 21 is fixedly connected to the side wall of the moving block 19. The side wall of the slider 21 is slidably connected inside the connecting frame 16. A limiting block 20 is fixedly connected to the side wall of the second clamping plate 5. The side wall of the limiting block 20 is rotatably connected to the inner wall of the connecting frame 16 and the side wall of the limiting block 20 is rotatably connected to the side wall of the moving block 19.

[0034] Working principle: When material in the bottom pipe of the pre-pressure tank passes through the hollow block 3, the internal filter screen 22 intercepts large particles or sediments in the material, preventing impurities from entering the downstream pipe and causing blockage. When impurities accumulate on the surface of the filter screen 22 and need to be cleaned, the operator moves the anti-slip strip 12 on the outer wall of the rotating plate 11, causing the rotating plate 11 to rotate around the side wall of the connecting plate 10, thereby driving the internal second rotating shaft 13 and the retaining ring 14 to rotate synchronously, causing the outer wall of the retaining ring 14 to disengage from the side wall of the retaining block 9 on the baffle 7, releasing the lock on the baffle 7. Then, the handle 8 is pulled, causing the baffle 7 and the connected filter screen 22 to slide out along the inner wall of the hollow block 3, realizing the quick disassembly of the filter screen. After cleaning, push the filter screen 22 back into the hollow block 3, rotate the rotating plate 11 in the opposite direction to make the retaining ring 14 re-lock the retaining block 9, and then tighten the retaining ring 14 along the outer wall of the second rotating shaft 13 with the nut 15 to complete the reset and installation of the filter screen, which greatly shortens the operation time of cleaning and maintenance and reduces the impact of equipment downtime.

[0035] During the connection process between the component and the bottom pipeline of the pre-pressure tank, initial positioning is achieved by mating the first flange 1 and the second flange 2. Then, the first clamping plate 4 and the second clamping plate 5 are moved so that their inner walls fit against the outer walls of the two flanges. At this time, the limiting block 20 on the side wall of the second clamping plate 5 is embedded in the inner wall of the connecting frame 16 on the first clamping plate 4. The operator turns the handle 18 to drive the screw 17 to rotate inside the connecting frame 16. The screw 17 drives the moving block 19 on the outer wall to slide along the inner wall of the connecting frame 16. The slider 21 can prevent the moving block 19 from rotating, so that the side wall of the moving block 19 tightly abuts against the limiting block 20. Thus, the clamping force of the first clamping plate 4 and the second clamping plate 5 achieves rapid fixation of the two flanges without the need to loosen or tighten the bolts one by one. This improves the efficiency of installation and disassembly, ensures the sealing of the pipeline connection, and ensures the stable operation of material conveying at the bottom of the pre-pressure tank.
