Abstract
Description
Technical Field
[0001] This utility model relates to the field of drain cleaner technology, and more specifically, to a drain cleaner cleaning device. Background Technology
[0002] Coal gas is an important fuel and byproduct in the production process of iron and steel metallurgical enterprises, and is transported to various users through gas pipelines. These pipelines transport water vapor-saturated coal gas, which also carries impurities and solid particles such as CO2, SO2, H2S, phenol, cyanide, naphthalene, and oil mist. During transportation, due to condensation and adsorption, a large amount of corrosive condensate and scale accumulates on the inner wall of the pipe. The accumulation of these products increases the pipeline load, accelerates the electrochemical corrosion of the gas pipe wall, and reduces the pipeline's lifespan. Excessive accumulation can reduce the pipeline's cross-sectional area, causing gas pressure fluctuations. Severe accumulation can even form a water seal in low-lying sections of the pipeline, stopping gas delivery and causing production shutdowns. Drainage devices can effectively remove condensate and scale from inside the pipeline, extending its service life.
[0003] In existing technologies, when the drainer is in operation, the existing gas in the steel plant contains a lot of impurities. When mixed with condensate, it produces viscous scale, which easily remains inside the drainer and in the drain pipe. Over time, a scale layer will form inside the drainer pipe. As the scale layer thickens, the drainer will eventually be unable to discharge condensate, and condensate in the main pipe will also be unable to enter the drainer, causing the drainer to malfunction and liquid to accumulate in the pipe. Therefore, there is an urgent need for a drainer cleaning device. Utility Model Content

[0032] In existing technologies, when the drainer is in operation, the existing gas in the steel plant contains a lot of impurities. When mixed with condensate, it produces viscous scale, which easily remains inside the drainer and in the drain pipe. Over time, a scale layer will form inside the drainer pipe. As the scale layer thickens, the drainer will eventually be unable to discharge condensate, and condensate in the main pipe will also be unable to enter the drainer, causing the drainer to malfunction and liquid to accumulate in the pipe. Therefore, there is an urgent need for a drainer cleaning device.
[0033] Please refer to Figure 1 This embodiment provides a drain cleaner cleaning device, which can effectively improve the technical problems mentioned above. It can clean the inside of the drain without disassembling the drain, making cleaning convenient, efficient, and extending the cleaning cycle.
[0034] In this embodiment, the drain cleaner is mainly used in the steel smelting industry. The drain can effectively remove condensate and dirt from inside the pipes, extending the service life of the pipes. During operation, condensate from the gas pipeline enters the drain through the downcomer and then reaches the leak-proof component 6. When the water level inside the cylinder rises to a certain position, the weight of the float is less than the buoyancy, causing the float to float up, and the condensate is discharged through the outlet. After the condensate is discharged, the water level inside the cylinder drops, the weight of the float is greater than the buoyancy, causing the float to descend and be isolated from the outside atmosphere by the conical gasket. In other embodiments, the drain cleaner can also be applied to other industrial fields, which are not specifically limited here.
[0035] The drain cleaning device includes a drain body 1, an inlet valve 11, a drain valve, and a ground drain pipe 17. The drain body 1 has a cleaning hole and a drain hole 10. The cleaning hole is used to connect to an external water source and is located higher than the drain hole 10. The inlet valve 11 is located at the cleaning hole, and the drain valve is located at the drain hole 10. The ground drain pipe 17 is connected to the drain hole 10. One end of the ground drain pipe 17 is sealed with a flange cover, and the other end of the ground drain pipe 17 is connected to a sewage tank, so that the collected sewage is directly discharged into the sewage tank.
[0036] In this embodiment, the inlet valve 11 and the drain body 1 are connected by a flange, and the drain valve and the drain body 1 are connected by a flange.
[0037] To prevent gas or liquid leakage, each flange in this embodiment is equipped with a graphite gasket to ensure the sealing of the flange connection.
[0038] In this embodiment, the drain cleaning device includes a primary valve 3, a secondary valve 2, and a drain pipe. Both the primary valve 3 and the secondary valve 2 are mounted on the drain pipe, and the two ends of the drain pipe are connected to the drain body 1 and the gas pipeline 4, respectively. Specifically, the drain pipe includes multiple short pipes arranged sequentially in a straight line. The primary valve 3 and the secondary valve 2 are respectively located between two adjacent short pipes and connected by flanges.
[0039] It should be noted that current technology typically involves disassembling and cleaning the drain to troubleshoot malfunctions. This method has several problems. First, the number of drains in gas pipeline networks is enormous, requiring a large workforce for cleaning. Second, traditional drain cleaning requires opening the drain end cap and cleaning manhole to flush the inside with fire-fighting water. Without opening the manhole, it's impossible to effectively clean the internal contaminants, which are usually carried out by the gas. Incomplete cleaning can cause blockages, affecting the drain's normal operation and potentially leading to safety accidents. Furthermore, cleaning drains using current technology is very tedious, requiring at least three people and two hours per drain, resulting in low efficiency and high manpower consumption. Also, because there is no drain pipe at the bottom of the drain, impurities, stains, and wastewater can spread to the surrounding area during cleaning, causing environmental pollution. Finally, the drain pipe bends are prone to blockage and difficult to unclog. To address the aforementioned technical problems, the drain cleaning device provided in this embodiment connects a fire hose reel 12 to the external cleaning port and opens the inlet valve 11. Water enters the drain body 1 through the cleaning port for rinsing. The drain valve is then opened, allowing the rinsed wastewater to flow directly out of the drain body 1 through the drain hole 10 and collect in the drain pipe for discharge. This drain cleaning device can clean the interior of the drain body 1 without disassembling it, enabling convenient and efficient cleaning, effectively improving the cleaning efficiency, extending the cleaning cycle, and reducing costs.
[0040] In this embodiment, the drain hole 10 includes a first drain hole 20 and a second drain hole 21. The first drain hole 20 and the cleaning hole are arranged opposite to each other, and the second drain hole 21 is located at the bottom of the drain body 1. Specifically, the drain body 1 is cylindrical, and the cleaning hole and the first drain hole 20 are respectively located at opposite ends of the drain body 1.
[0041] Understandably, the drain valve includes a first drain valve 13 and a second drain valve 15, with the first drain valve 13 disposed at the first drain hole 20 and the second drain valve 15 disposed at the second drain hole 21.
[0042] It should be noted that the height of the first drain hole 20 is lower than the height of the cleaning hole. That is, the cleaning hole is located above the end of the drain body 1, and the first drain hole 20 is located below the end of the drain body 1. In this way, when external water enters the interior of the drain body 1 through the cleaning hole, the water can thoroughly clean the interior of the drain body 1 from top to bottom. The wastewater after cleaning can flow directly out from the first drain hole 20 located below the end of the drain body 1, making cleaning more efficient and convenient.
[0043] It should also be noted that the drain cleaning device also includes a movable flange bend 14, with both ends of the movable flange bend 14 connected to the first drain hole 20 and the ground drain pipe 17, respectively. Specifically, the movable flange bend 14 has a "7" structure and includes a horizontal pipe and a vertical pipe that are connected. The horizontal pipe is connected to the first drain hole 20, and the vertical pipe is connected to the ground drain pipe 17.
[0044] Specifically, the length of the horizontal pipe is less than the length of the vertical pipe, thereby ensuring that the sewage flowing out of the drain body 1 can quickly flow into the ground drain pipe 17.
[0045] Furthermore, the drain cleaning device also includes a first drain pipe 16, which is connected to the second drain hole 21 and the ground drain pipe 17. The first drain pipe 16 is located at the bottom center of the drain body 1, and the second drain valve 15 is disposed on the first drain pipe 16.
[0046] In addition, the drain cleaning device also includes an ascending pipe 5, an overflow pipe 7, and a second drain pipe 8. One end of the ascending pipe 5 is connected to the top of the drain body 1, and the other end of the ascending pipe 5 is connected to the overflow pipe 7. The two ends of the second drain pipe 8 are connected to the overflow pipe 7 and the ground drain pipe 17, respectively. Specifically, the overflow pipe 7 is horizontally arranged, and the ascending pipe 5 and the second drain pipe 8 are arranged vertically. The upper end of the second drain pipe 8 is located below the outlet of the overflow pipe 7 and is used to collect the water flowing out of the overflow pipe 7. The lower end of the second drain pipe 8 is connected to the ground drain pipe 17.
[0047] Specifically, a leak-proof component 6 is installed at the top of the riser pipe 5 to prevent liquid leakage.
[0048] In this embodiment, the drain cleaning device further includes a cleaning box 9, which is installed on the second drain pipe 8. The cleaning box 9 can collect sludge and other dirt, thereby extending the cleaning cycle of the drain.
[0049] More specifically, the second drain pipe 8 can be connected to the surrounding structure via the flat steel 18, for example, by welding the flat steel 18 to the surrounding steel structure.
[0050] Furthermore, to ensure the installation stability of the drain body 1, a triangular support frame 19 is provided at the bottom of the drain body 1.
[0051] In summary, this utility model embodiment provides a drain cleaner cleaning device, which includes a drain body 1, an inlet valve 11, a drain valve, and a ground drain pipe 17. The drain body 1 has a cleaning hole and a drain hole 10. The cleaning hole is used to connect to an external water source and is located higher than the drain hole 10. The inlet valve 11 is located at the cleaning hole, and the drain valve is located at the drain hole 10. The ground drain pipe 17 is connected to the drain hole 10. When it is necessary to clean the drain body 1, a fire hose connection 12 is connected to the external cleaning hole, and the inlet valve 11 is opened. Water enters the drain body 1 through the cleaning hole for rinsing. The drain valve is opened, and the rinsed wastewater flows directly out of the drain body 1 through the drain hole 10 and collects in the drain pipe for discharge. This drain cleaner cleaning device can clean the inside of the drain body 1 without disassembling it, which can carry out cleaning work conveniently and efficiently, effectively improving the cleaning efficiency of the drain, extending the cleaning cycle of the drain, and reducing costs.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
