Description

Technical Field

[0001] This utility model relates to a pipe dredging and cleaning device. Background Technology

[0002] In actual production at the polyester division, the PTA raw material pipeline needs to be cleaned twice a week, and dredged and cleaned eight times a month. During the PTA pipeline cleaning process, the PTA equipment and pipeline valves must be shut down. After disassembling the PTA pipeline, cleaning workers must wear protective masks and use scrapers to clean the pipeline, removing the PTA adhering to the inner wall. Because the pipeline is located 500mm above the ground in a confined space, workers can only squat or bend over to clean it. The cleaning process generates a large amount of PTA dust, posing an occupational risk of pneumoconiosis to the workers. Due to the confined space and inconvenient operation, there is also a risk of cuts from the scraper during cleaning. Since the cleaning operation takes approximately 30 minutes per person, and workers must remain in a squatting or bending position, there is a risk of knee and lower back strain. Furthermore, this cleaning operation requires eight people to complete, resulting in high labor costs and low cleaning efficiency. Utility Model Content

[0038] See Figures 1 to 13 The pipe dredging and cleaning device shown includes a drive rod 1, a sealing cap 2, and a cleaning component 3, wherein:

[0039] The pipe 10 to be cleaned is circular, the sealing cap 2 is disc-shaped, and the drive rod 1 is cylindrical. The drive rod 1 is slidably mounted on the sealing cap 2, which has a through hole in its center, extending through the thickness of the sealing cap 2. The sealing cap 2 is movable outside the drive rod 1, meaning the drive rod 1 can move along the through hole in the center of the sealing cap 2. The sealing cap 2 is used for a sealed connection with the pipe 10 to be cleaned. During cleaning, after the sealing cap 2 is fixedly connected to the pipe 10, it can drive the drive rod 1 to move. The sealing cap 2 seals the opening of the pipe to be cleaned, effectively isolating the material dust generated during the cleaning process inside the pipe 10, preventing the splashing of PTA material dust during manual cleaning, and effectively protecting the surrounding environment.

[0040] In some embodiments, the through hole on the sealing cap 2 is larger than the diameter of the drive rod 1. To prevent material dust generated during the cleaning process from overflowing from the gap between the through hole of the sealing cap 2 and the drive rod 1, the device also includes a support plate 7. The support plate 7 is sleeved on the drive rod 1, that is, the support plate 7 has an opening with a diameter slightly larger than the outer circumference diameter of the drive rod 1. The support plate 7 is connected to the sealing cap 2 and is located on the side of the sealing cap 2 away from the cleaning component 3. The support plate 7 can block the gap between the through hole of the sealing cap 2 and the drive rod 1, effectively isolating the material dust generated during the cleaning process inside the pipe 10, and better preventing the dust of PTA material from splashing during manual cleaning. In addition, when the drive rod 1 of different sizes is replaced, the sealing cap 2 does not need to be replaced and can be used interchangeably, saving costs.

[0041] In some implementations, the surface area of ​​the support plate 7 is smaller than that of the sealing cap 2, which saves costs while ensuring the sealing effect.

[0042] In a preferred embodiment, a gasket is provided between the support plate 7 and the sealing cap 2. The gasket is sleeved on the drive rod 1 and is made of silicone, which provides a better sealing effect and better prevents dust from splashing during manual unclogging and cleaning.

[0043] See Figure 1-6 The support plate 7 is detachably connected to the sealing cap 2, and the sealing cap 2 is detachably connected to the pipe 10 to be cleaned. The support plate 7 and the sealing cap 2 have corresponding first mounting holes. A first fastener 8 is installed in the first mounting hole to connect the support plate 7 and the sealing cap 2. The sealing cap 2 has a second mounting hole, and the pipe 10 to be cleaned has a connecting flange. The connecting flange has a hole corresponding to the second mounting hole on the sealing cap 2. A second fastener 9 is installed in the second mounting hole and the hole on the connecting flange to connect the sealing cap 2 and the pipe 10 to be cleaned. When disassembling, removing the second fastener 9 allows the sealing cap to be moved away from the pipe 10 to be cleaned, making installation and disassembly convenient. The first fastener 8 and the second fastener 9 can be a bolt and nut assembly.

[0044] In this example, the cleaning component 3 is connected to one end of the drive rod 1. The outer contour of the cleaning component 3 matches the inner wall contour of the pipe 10 to be cleaned. When the cleaning component 3 is inserted into the pipe 10, an opening 311 is provided on the cleaning component 3. The opening 311 is recessed from the outer peripheral wall edge of the end face of the cleaning component 3 towards the center of the cleaning component 3. The opening 311 extends through the thickness direction of the cleaning component 3, which is consistent with the extension direction of the drive rod 1. The outer peripheral wall of the end face of the cleaning component 3 forms a scraping surface. The scraping surface is relatively sharp and can scrape away impurities from the inner wall of the pipe 10 to be cleaned. The scraping surface of the cleaning component 3 is arc-shaped, such as a circular arc.

[0045] See Figure 3 The cleaning component 3 includes a cleaning body 31 and a boss 32. Both the cleaning body 31 and the boss 32 can be circular. The cleaning body 31 and the boss 32 are coaxially arranged. The outer peripheral wall of the end face of the cleaning body 31 forms a scraping surface. The boss 32 is disposed on the surface of the cleaning body 31 facing the other end of the drive rod 1. The boss 32 is located in the middle of the cleaning body 31, and the surface area of ​​the boss 32 is smaller than the surface area of ​​the cleaning body 31. An opening 311 is disposed on the cleaning body 31. The opening 311 is recessed from the edge of the outer peripheral wall of the end face of the cleaning body 31 toward the center of the cleaning body 31. The opening 311 penetrates the thickness direction of the cleaning body 31.

[0046] Furthermore, a reinforcing part 4 is provided on the surface of the cleaning component 3 facing the other end of the drive rod 1. One end of the reinforcing part 4 is connected to the boss 32, and the other end of the reinforcing part 4 extends towards the edge near the cleaning body 31, and extends to the surface of the cleaning body 31 where no opening 311 is made. Providing the reinforcing part 4 can enhance the strength of the cleaning component 3 and improve the cleaning effect.

[0047] In some embodiments, the reinforcing part 4 is rod-shaped and is arranged radially along the cleaning body 31. Multiple reinforcing parts 4 are provided, and the multiple reinforcing parts 4 are evenly arranged radially along the cleaning body 31.

[0048] In this example, multiple openings 311 are provided, and the multiple openings 311 are arranged around the circumference of the cleaning component 3; the openings 311 can be V-shaped, U-shaped or square.

[0049] In some embodiments, the cleaning component 3 is detachably connected to one end of the drive rod 1. For example, a slot is provided on the cleaning body 31 of the cleaning component 3, and one end of the drive rod 1 is inserted into the slot to facilitate the replacement of the cleaning component 3.

[0050] In some embodiments, the boss 32 and the cleaning body 31 are provided with corresponding through holes 33. The through holes 33 penetrate the thickness direction of the cleaning component 3. The through holes allow PTA material to pass through the through holes 33, which facilitates the cleaning of PTA material and can also reduce weight. Multiple through holes 33 can be provided, and multiple through holes 33 are arranged around the circumference of the boss 32.

[0051] In this example, the drive rod 1 is made of a deformable material, meaning it is flexible and can extend into pipes 10 of different shapes. See [reference needed]. Figure 11-13 The Y-shaped pipe 10 shown is first folded into a shape that fits the pipe 10, and then the drive rod 1 is inserted into the pipe 10. The drive rod 1 is preferably made of stainless steel.

[0052] In some embodiments, a handle 6 is provided at the other end of the drive rod 1. The handle 6 is connected to the drive rod 1 and is vertically arranged. The handle 6 facilitates operator hand-held operation and provides good operating comfort. Preferably, the handle 6 is detachably connected to the other end of the drive rod 1.

[0053] In this example, the device also includes a limiting plate 5, which is sleeved on the drive rod 1 and fixedly connected to the drive rod 1. The limiting plate 5 is close to the other end of the drive rod 1 and is located between the handle 6 and the sealing cap 2. The limiting plate 5 is close to the handle 6. When the operator holds the handle 6 to operate, the limiting plate 5 can prevent the handle 6 from falling into the pipe 10.

[0054] In some embodiments, the limiting plate 5 is circular, and the surface area of ​​the limiting plate 5 is smaller than the surface area of ​​the cleaning component 3.

[0055] The specific implementation method of the pipe dredging and cleaning device in this example is as follows:

[0056] Insert the cleaning component 3 into the pipe 10 to be cleaned, then fix the sealing cap 2 to the pipe 10 to be cleaned, and then drive the drive rod 1 to move the cleaning component up or down. By moving the drive rod 1 multiple times, the PTA material attached to the inner wall of the pipe 10 and the PTA material blocking the bottom of the pipe 10 are thoroughly cleaned. After the operation is completed, remove the device from the pipe 10.

[0057] The advantages of the pipe dredging and cleaning device in this example are:

[0058] 1. Save on labor costs

[0059] Previously, PTA pipe cleaning operations required a single person to complete in about 30 minutes. With the pipe cleaning device in this example, operators can clean pipes online, with each cleaning operation taking about 3 minutes. Furthermore, operators can operate upright, avoiding the risk of knee and lower back strain.

[0060] 2. Safe and reliable

[0061] The pipe cleaning device in this example effectively eliminates occupational diseases such as pneumoconiosis caused by pipe cleaning operations and eliminates the safety hazard of cutting the human body with scrapers; at the same time, the operator does not need to disassemble the pipe, eliminating the risk of impact.

[0062] 3. Environmental protection

[0063] Using the pipe cleaning device in this example, the material dust generated during the cleaning process is isolated inside the pipe by a sealed cap, preventing the dust from splashing during manual cleaning of PTA materials and effectively protecting the surrounding environment.

[0064] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
