Description

Technical Field

[0001] This utility model relates to the field of natural gas pipelines, and in particular to a natural gas pipeline impurity treatment device with a cleaning function. Background Technology

[0002] Natural gas pipelines are pipelines that transport natural gas from extraction sites or processing plants to urban gas distribution centers or industrial users. They are also known as gas transmission pipelines. Natural gas pipelines are a vital component of energy transportation and supply, and maintaining pipeline safety is of paramount importance.

[0003] A search revealed that the Chinese patent "A device for cleaning impurities inside a natural gas pipeline" (authorization announcement number CN220346749U) includes an installation cylinder and an adjustment unit. The installation cylinder has a first sliding rod slidably connected to its upper end via a limiting slide plate. Both the upper end of the outer arc surface of the installation cylinder and the upper end of the outer arc surface of the first sliding rod are provided with mounting seats. A ring-shaped, evenly distributed X-shaped rotating frame is rotatably connected between the two mounting seats via a pin. A cleaning brush is rotatably connected to the outer end of each X-shaped rotating frame via a damping rotating shaft. The adjustment unit includes an internally threaded sleeve, which is rotatably connected to a groove in the middle of the top wall of the installation cylinder via a bearing. The first sliding rod and the internally threaded sleeve... Threaded connection; it can be adjusted in real time according to the size of natural gas pipelines of different specifications, and uses a cleaning brush to clean impurities. However, the above method has the following defects in actual use: during the cleaning process, it only uses the cleaning brush to wipe away impurities, and the inner wall of the pipeline needs to be wiped repeatedly to achieve a good impurity removal effect. This repeated movement path increases the workload of users and affects the impurity removal efficiency. In addition, it is not easy to clean the impurities after wiping during the impurity removal process, resulting in impurities remaining inside the pipeline, increasing the subsequent workload. At the same time, when the inner diameter of the pipeline changes, it is necessary to stop the machine for adjustment, and the fit with the inner wall of the pipeline after adjustment is not stable enough.

[0004] Therefore, a natural gas pipeline impurity treatment device with cleaning function is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a natural gas pipeline impurity treatment device with cleaning function to solve the above-mentioned problems, thereby improving the problems of low impurity removal efficiency and the need for separate subsequent cleaning operations.

[0007] Preferably, the cleaning assembly further includes a set of dust collection boxes, which are evenly distributed along the axis of the mounting rod.

[0008] Preferably, a piston tube is sleeved on the outside of the drive rod and installed inside the round box.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] In practical implementation: such as Figure 1-4 As shown, a natural gas pipeline impurity treatment device with cleaning function includes an installation rod 100 and a set of brush plates 200 disposed on its outer side; it also includes a cleaning component 300, which is disposed on the outer side of the installation rod 100 and is used to improve the pipeline impurity cleaning ability and clean impurities; wherein, the cleaning component 300 includes a circular box 310 disposed on the installation rod 100, a set of inclined grooves 320 and a set of drive rods 330, the brush plates 200 are located on the outer side of the circular box 310, one end of the drive rod 330 passes through the circular box 310 and is fixedly connected to one side of the brush plate 200, the inclined grooves 320 are opened to one side of the circular box 310, and a ring-shaped strong magnet 314 is embedded on the outer side of the circular box 310.

[0024] like Figure 1 and Figure 2 As shown, the cleaning assembly 300 also includes a set of dust collection boxes 340, which are evenly distributed along the axis of the mounting rod 100.

[0025] The user can connect the mounting rod 100 to the external driver, and then place the brush plate 200 and the mounting rod 100 into the natural gas pipeline to be treated. Then, the driver drives the mounting rod 100 to rotate, and the device is advanced along the pipeline. During the movement, gas is introduced into the round box 310, and then the gas is discharged along the inclined groove 320, forming an air knife on the inner wall of the pipeline. During the rotation, impurities are blown away from the inner wall of the pipeline, relieving the cleaning pressure of the subsequent brush plate 200. Then, the gas drives the drive rod 330 to apply pressure to the brush plate 200, ensuring that it adheres to the inner wall of the pipeline. This method also allows the brush plate 200 to move according to the change of the inner diameter of the pipeline. Then, the brush plate 200 is used to wipe the inner wall of the pipeline. During the impurity removal process, the annular strong magnet 314 is used to adsorb and collect metal debris and magnetic rust in the pipeline, completing a variety of impurity removal operations. After the impurity removal is completed, the dust collection box 340 will collect the treated impurities, achieving the cleaning treatment of the pipeline.

[0026] like Figure 2 and Figure 3 As shown, a piston tube 331 is sleeved on the outside of the drive rod 330 and installed inside the round box 310. A piston plate 332 fixedly connected to one end of the drive rod 330 is installed inside the piston tube 331. A spring is installed between the piston tube 331 and the piston plate 332. An air inlet pipe 333 is provided at one end of the piston tube 331.

[0027] Gas is introduced into piston tube 331 through air inlet pipe 333. The gas then compresses piston plate 332, thereby applying pressure to drive rod 330 and brush plate 200. With the spring setting, the gas introduction can be stopped after each impurity removal operation. Then the spring drives brush plate 200 to move towards the axis of round box 310 to complete the storage.

[0028] like Figure 1 and Figure 2 As shown, the round box 310 has an air collection box 311 inside, and an air pump 312 is installed inside the air collection box 311. A three-way pipe 313 is installed at the input end of the air pump 312, and the end of the air inlet pipe 333 away from the piston pipe 331 extends into the interior of the air collection box 311.

[0029] Start the air pump 312 to guide the gas into the gas collection box 311 along the three-way pipe 313, and then discharge it along the air inlet pipe 333;

[0030] It should be noted that the air pump 312 is powered by a built-in power supply, which is located in the circular box 310.

[0031] like Figure 3 As shown, a through hole 334 is provided on the outer side of the piston tube 331, and the inner diameter of the through hole 334 is smaller than the inner diameter of the intake pipe 333.

[0032] Since the inner diameter of the through hole 334 is smaller than the inner diameter of the air inlet pipe 333, the gas can pressurize the brush plate 200 while a small amount of gas can be discharged through the through hole 334. On the one hand, this reduces the phenomenon of excessive pressure on the brush plate 200. On the other hand, the gas is discharged along the inclined groove 320 to complete the blowing and impurity removal operation.

[0033] like Figure 1 and Figure 2 As shown, an annular box 110 is sleeved on the outside of the mounting rod 100. A conduit 341 is installed on the dust collection box 340 and slidably connected to the inside of the annular box 110. The two ends of the three-way pipe 313 away from the air pump 312 pass through the round box 310 and extend into the inside of the annular box 110. An annular filter plate 111 is installed inside the annular box 110.

[0034] By using the three-way pipe 313 to draw air, a negative pressure is formed inside the annular box 110, which causes the conduit 341 on the dust collection box 340 to draw in gas, thereby adsorbing and collecting impurities in the pipe, and then intercepting the impurities with the annular filter plate 111.

[0035] like Figure 1 and Figure 2 As shown, a linkage rod 342 is installed between the conduit 341 and the drive rod 330.

[0036] By using the linkage rod 342, when the brush plate 200 automatically adjusts according to the inner diameter of the pipe, it can drive the dust collection box 340 to change position, ensuring the distance between it and the inner wall of the pipe, thereby ensuring the cleaning and dust collection effect.

[0037] Working principle: The user can connect the mounting rod 100 to the external driver, and then place the brush plate 200 and the mounting rod 100 into the natural gas pipeline to be treated. The driver then drives the mounting rod 100 to rotate, simultaneously advancing the device along the pipeline. During this movement, gas is introduced into the circular box 310, and then discharged along the inclined groove 320, forming an air knife on the inner wall of the pipeline. During rotation, impurities are blown away from the inner wall of the pipeline, relieving the cleaning pressure on the subsequent brush plate 200. The air pump 312 is then activated, allowing gas to be introduced into the gas collection box 311 along the three-way pipe 313, and then discharged along the air inlet pipe 333. The air inlet pipe 333 guides the gas into the piston pipe 331, whereby the gas compresses the piston plate 332, thereby applying pressure to the drive rod 330 and the brush plate 200 to ensure a good fit with the inner wall of the pipeline. This method also allows the brush plate 200 to move according to changes in the inner diameter of the pipeline. The inner wall of the pipe is then wiped with a brush plate 200. During the impurity removal process, a ring-shaped strong magnet 314 is used to adsorb and collect metal debris and magnetic rust in the pipe, completing a variety of impurity removal operations. After the impurity removal is completed, air is drawn in through a three-way pipe 313 to create a negative pressure in the ring box 110, thereby drawing gas through the conduit 341 on the dust collection box 340 to adsorb and collect impurities in the pipe. Combined with the ring-shaped filter plate 111, the impurities are intercepted. The entire device can use a variety of methods such as blowing impurities, wiping impurities, and magnetic impurity removal, eliminating repetitive movement paths. While ensuring the impurity removal effect, it reduces the user's workload and improves the impurity removal efficiency. At the same time, it can collect and clean impurities without the need for separate subsequent processing. During the entire impurity removal process, the brush plate 200 can be automatically adjusted according to the inner diameter of the pipe without stopping the machine, and the adhesion between the brush plate 200 and the inner wall of the pipe is guaranteed.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
