Technical Field

[0001] This utility model relates to the field of pipeline flushing devices, specifically a pipeline flushing device. Background Technology

[0002] In chemical production, pipelines are widely used to transport highly viscous, highly corrosive, high-temperature, or easily crystallizing chemical media. This leads to the formation of scale, deposits, or chemical reaction residues inside the pipelines, affecting the flow efficiency of the media. In such cases, flushing equipment or tools are needed to treat the pipelines.

[0003] Chinese Patent Application No. CN202220014129.8 discloses a mobile pipe flushing device. This solution is equipped with a water storage device to store water, and then flushes the end pipes individually through the flushing pipes, instead of flushing all pipes at once, which improves the flushing efficiency of the end pipes. In addition, the mobile device makes the device easy to move and use. Furthermore, by setting up a return water pipe, the flushing water can be recycled and reused, saving water resources.

[0004] Pipe flushing devices require specific water pressure for flushing, making pipe positioning crucial. Existing pipe positioning flushing structures are limited and cannot quickly locate or separate pipes of different diameters, thus reducing the convenience of the flushing process. Therefore, a new pipe flushing device is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the positioning of the pipeline is crucial when using a pipeline flushing device. Existing pipeline positioning and flushing structures are simple and cannot quickly position or separate pipelines of different diameters, which reduces the flushing convenience of the pipeline flushing device. This utility model proposes a pipeline flushing device.

By installing the positioning ring and the positioning block, the positioning effect of the pipeline flushing device can be improved.

[0007] Preferably, the bottom four corners of the operating frame are fixedly connected to bases, and the outer end of the operating frame is equipped with baffles. The baffles are L-shaped, and the installation of baffles improves the protective effect of the device structure during operation.

[0008] Preferably, a motor is installed at the drive end of the baffle, and a bidirectional screw is installed at the drive end of the motor. The outer end of the bidirectional screw is threaded with symmetrically distributed sleeve blocks.

[0009] Preferably, a positioning frame is fixedly connected to the upper end of the sleeve block, and one end of the positioning ring is connected to the positioning frame. By installing the positioning frame, the positioning ring and the connected components can operate stably.

[0010] Preferably, the inner end of the positioning frame is provided with a receiving groove, and the outer end of the operating frame is fixedly connected with a supply box. By installing the receiving groove, further positioning and adjustment can be facilitated.

[0011] Preferably, the top of the supply box is fixedly connected to an inlet, the right end of the supply box is fixedly connected to a connecting pump, the outer end of the connecting pump is fixedly connected to a conveying pipe, and the other end of the conveying pipe away from the connecting pump is fixedly connected to a spray pipe. By installing the supply box and the conveying pipe, the rinsing operation of the device can be made more convenient.

[0012] Preferably, a flushing head is installed at the front end of the spray pipe, and a spray nozzle is fixedly connected to the outer end of the flushing head.

[0014] The advantages of this utility model are:

[0015] 1. This utility model, through the structural design of positioning rings and positioning blocks, allows the flushing pipe to be placed inside a pair of positioning rings when the flushing device is in use. The diameter of the positioning rings is larger than that of commonly used chemical pipes. During flushing and positioning, multiple hydraulic cylinders are activated. The hydraulic cylinders, in conjunction with hydraulic rods, move the positioning blocks to position them outside the chemical pipe. The multiple positioning blocks position the pipe, enabling the device to quickly locate the pipe. This allows the flushing device to be flexibly adjusted according to different pipe diameters or installation environments, making it suitable for various specifications and working conditions. It also reduces secondary processing or replacement of special parts due to equipment incompatibility, improving versatility and adaptability. It ensures accurate pipe flushing points, improves flushing efficiency, enhances operational stability, reduces displacement risks during high-pressure flushing or vibration, and improves the positioning effect of the pipe flushing device.

[0016] 2. Through the structural design of the sleeve block, the sleeve block can engage with the rotating bidirectional screw. A pair of sleeve blocks can adjust their position under the force of the screw thread. A pair of movable sleeve blocks can drive the positioning frame and positioning ring to move in opposite directions. This allows the device to not only be fixed in multiple ways according to the diameter of different pipes, but also to be adjusted according to the length of the pipe, further improving the positioning effect of the pipe flushing device.

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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a pipe flushing device. (Refer to...) Figures 1-5 A pipeline flushing device includes an operating frame 1. A pair of symmetrically distributed positioning rings 9 are slidably connected to the upper part of the operating frame 1. Multiple connecting rods 10 are fixedly connected to the inner ends of the positioning rings 9. Limiting rings 11 are installed on the inner ends of the connecting rods 10. Positioning blocks 12 arranged in a ring are slidably connected to the inner ends of the limiting rings 11. A hydraulic cylinder 13 is fixedly connected to the outer end of the positioning rings 9. A hydraulic rod 14 is installed on the transmission end of the hydraulic cylinder 13. A flushing head 20 is movably connected to the outer side of one of the positioning rings 9. By installing the positioning rings 9 and positioning blocks 12, when the flushing device is in use, the flushing pipeline is placed inside the pair of positioning rings 9. The diameter of the positioning rings 9 is larger than the diameter of commonly used chemical pipelines. Furthermore, during flushing and positioning, multiple hydraulic cylinders 13 are activated. The hydraulic cylinders 13, in conjunction with the hydraulic rods 14, move the positioning blocks 12 to the outside of the chemical pipeline. The multiple positioning blocks 12 position the pipeline, allowing the device to quickly locate the pipeline. This makes the flushing device flexible to adjust according to different pipeline diameters or installation environments, suitable for various specifications and working conditions. It also reduces secondary processing or replacement of special parts due to equipment incompatibility, improving versatility and adaptability. It ensures accurate pipeline flushing points, improves flushing efficiency, enhances operational stability, reduces displacement risks during high-pressure flushing or vibration, and improves the positioning effect of the pipeline flushing device.

[0027] Reference Figure 1The bottom of the operating frame 1 is fixedly connected to the four corners of the base 2. The outer end of the operating frame 1 is equipped with a baffle 3. The baffle 3 has an L-shaped structure. By installing the baffle 3, the L-shaped baffle 3 can form a protective structure at the outer end of the motor 4, so that the rinsing water sprayed to the outside of the motor 4 during the cleaning process can be reduced, thus improving the protective effect of the device structure.

[0028] Reference Figure 1 and Figure 3 A motor 4 is installed at the transmission end of the baffle 3, and a bidirectional screw 5 is installed at the transmission end of the motor 4. The outer end of the bidirectional screw 5 is threaded with symmetrically distributed sleeve blocks 6. By installing the sleeve blocks 6, the sleeve blocks 6 can engage with the rotating bidirectional screw 5 through threaded action. A pair of sleeve blocks 6 can adjust their position under the threaded force. A pair of moving sleeve blocks 6 can drive the positioning frame 7 and the positioning ring 9 to move in opposite directions. This allows the device to not only be fixed in multiple ways according to the diameter of different pipes, but also to be adjusted according to the length of the pipe, further improving the positioning effect of the pipe flushing device.

[0029] Reference Figures 1-3 The upper end of the sleeve block 6 is fixedly connected to the positioning frame 7, and one end of the positioning ring 9 is connected to the positioning frame 7. By installing the positioning frame 7, the positioning frame 7 can form a support structure at the outer end of the positioning ring 9, so that the positioning ring 9 and the connected components can operate stably.

[0030] Reference Figure 1 and Figure 5 The inner end of the positioning frame 7 is provided with a receiving groove 8, and the outer end of the operating frame 1 is fixedly connected with a supply box 15. By installing the receiving groove 8, the diameter of the receiving groove 8 and the positioning frame 7 are both larger than that of most chemical pipes, making it easier to fix the pipes and facilitate further positioning and adjustment.

[0031] Reference Figure 1 and Figure 5 The top of the supply box 15 is fixedly connected to the inlet 16, the right end of the supply box 15 is fixedly connected to the connecting pump 17, the outer end of the connecting pump 17 is fixedly connected to the conveying pipe 18, and the other end of the conveying pipe 18 away from the connecting pump 17 is fixedly connected to the spray pipe 19. By installing the supply box 15 and the conveying pipe 18, the supply box 15 stores moving rinsing water. With the help of the connecting pump 17 and the conveying pipe 18, the rinsing water can be conveniently transferred to the rinsing head 20, making the rinsing operation of the device more convenient.

[0032] Reference Figure 5A flushing head 20 is installed at the front end of the spray pipe 19, and a nozzle 21 is fixedly connected to the outer end of the flushing head 20. A spray frame 22 is fixedly connected to the right end of the operating frame 1 by bolts. By installing the flushing head 20 and the nozzle 21, and setting multiple annularly distributed nozzles 21 on the outside of the flushing head 20, the inside of the pipe can be flushed more conveniently and evenly when the device is flushing, making the flushing operation of the pipe flushing device more convenient.

[0033] Reference Figure 1 and Figure 4 The inner end of the operating frame 1 is provided with a limiting groove 24, and a slider 23 is slidably connected to the inner end of the limiting groove 24. The slider 23 is fixedly connected to the bottom end of the sleeve block 6. A pair of brackets 25 are bolted to the front side of the upper end of the operating frame 1. A flushing ring 26 is installed on the inner end of the pair of brackets 25. By installing the limiting groove 24, when the position of the sleeve block 6 is adjusted, the slider 23 can be adjusted together with the movement of the sleeve block 6. The moving sleeve block 6 and slider 23 are limited by the limiting groove 24, so as to prevent the sleeve block 6 from driving the positioning frame 7 and positioning ring 9 to adjust the position and thus avoid displacement and overturning.

[0034] Working principle: When using this device, first, the pipe is passed through the flushing ring 26 and placed inside a pair of positioning rings 9 and a receiving groove 8. The motor 4 is started to rotate the bidirectional screw 5. The bidirectional screw 5 engages with a pair of sleeve blocks 6 through threaded action. Under the force of the threaded action, the pair of sleeve blocks 6 adjust their position. The moving sleeve blocks 6 can drive the positioning frame 7 and the positioning rings 9 to move in opposite directions. This allows the device to provide multiple fixations based on different pipe diameters. The diameter of the positioning rings 9 is larger than that of commonly used chemical pipes. Furthermore, during flushing and positioning, the flushing ring 26 is connected to the pump body and the pipe... The transmission components are connected to the supply box 15 to perform preliminary flushing. Multiple hydraulic cylinders 13 are activated, and the hydraulic cylinders 13, in conjunction with the hydraulic rods 14, move the positioning blocks 12 to the outside of the chemical pipeline. The multiple positioning blocks 12 position the pipeline, allowing the device to quickly locate the pipeline. This makes the flushing device flexible to be adjusted according to different pipeline diameters or installation environments, suitable for various specifications and working conditions. It also reduces secondary processing or replacement of special parts due to equipment incompatibility, improves versatility and adaptability, and ensures accurate pipeline flushing points.

[0035] After positioning, the connecting pump 17 starts to transfer the water source inside the supply tank 15 to the delivery pipe 18. The supply tank 15 stores the moving flushing water. With the connecting pump 17 and the delivery pipe 18, the flushing water can be conveniently transferred to the flushing head 20. The flushing head 20 is equipped with multiple ring-shaped nozzles 21 on the outside. When the device is flushing, it can more conveniently and evenly flush the inside of the pipe, making the flushing operation of the device more convenient.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
