Description

Technical Field

[0001] This invention relates to the technical field of pipeline water discharge and slag removal equipment, specifically a pipeline water discharge and slag removal equipment with filtration and fire suppression functions. Background Technology

[0002] Gas pipelines are specialized pipelines used in coal mines for extracting and releasing methane gas. During the gas extraction process in underground coal mines, some coal slag is often drawn into the main pipeline. As a result, the coal slag accumulates continuously in the main pipeline, which can easily cause blockages and affect the production of underground coal mines. Therefore, pipeline water drainage and slag removal equipment is needed to clean it. Pipeline water drainage and slag removal equipment, also known as pipeline slag remover, has the advantages of stable operation and simple operation.

[0003] During the use of pipeline descaling devices, the pipeline continuously extracts gas from the coal mine. However, as working hours increase, and due to factors such as operator errors and changes in mine internal gas pressure, the gas flow rate in the pipeline may exceed the equipment's safety specifications, leading to a malfunction of the pipeline descaling device. In this case, workers need to manually shut down the pipeline to prevent further damage to the equipment. However, this method of shutting down the pipeline often results in a more serious malfunction of the equipment. Furthermore, if workers are not focused enough and fail to notice the abnormality in the pipeline in time, they cannot take quick action to shut down the gas pipeline, resulting in more severe equipment damage and increased maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a pipeline water discharge and slag removal device with filtration and fire suppression functions, in order to solve the problem mentioned in the background art, where when the gas flow rate in the extraction pipeline exceeds the safety index of the equipment, it is inconvenient for workers to quickly perform operations such as sealing the pipeline, which in turn leads to further aggravation of equipment failure and increased maintenance costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pipeline water discharge and slag removal device with filtration and fire suppression functions, comprising a slag removal device body, a guide rod, and an acoustic detector. The guide rod is connected to the top center of the slag removal device body, and a connecting seat is connected to the bottom end of the guide rod through a limiting hole. A fixed seat is fixedly connected to the bottom end of the connecting seat. Movable rods are rotatably connected to both sides of the fixed seat, and a limiting rod is rotatably connected to the side of the movable rod away from the fixed seat. A support seat is sleeved on the outer wall of the limiting rod. A sealing plug is connected to the side of the limiting rod away from the movable rod, and a sealing airbag is connected to the side of the sealing plug away from the limiting rod. An inflation tube is connected to the limiting rod through an inflation groove. A threaded pin is fixedly connected to the bottom end of the guide rod, and a threaded hole for engaging with the threaded pin is opened inside the fixed seat. A fixing groove for engaging with the fixed seat is opened in the center of the bottom end of the slag removal device body.

[0006] Preferably, the support bases are symmetrically distributed about the vertical midline of the fixed base, and the bottom end of the support bases is fixedly connected to the bottom surface of the inner wall of the slag removal equipment body.

[0007] Preferably, the top of the fixed base has a limiting hole that mates with the guide rod, and the inflation tubes are symmetrically distributed about the vertical midline of the fixed base.

[0008] Preferably, telescopic rods are installed on both sides of the top of the slag removal equipment body, and the top of the telescopic rods is connected to a first rotating seat.

[0009] Preferably, a first connecting rod is movably connected inside the first rotating seat, and a second connecting rod is rotatably connected to the top of the first connecting rod.

[0010] Preferably, the bottom end of the second connecting rod is connected to a second rotating seat, and the bottom end of the second rotating seat is fixedly connected to a movable seat.

[0011] Preferably, pulleys are installed on both sides of the bottom of the movable seat, and a groove is provided at the top of the slag removal equipment body to connect with the pulleys.

[0012] Preferably, a protective box is connected to the top of the movable seat, and an acoustic wave detector is connected inside the protective box.

[0013] Preferably, the slag removal equipment has snap-fit ​​grooves on both sides of its main body, and the snap-fit ​​grooves are connected to a copper filter mesh.

[0014] Preferably, a slag discharge door is provided below the filter copper mesh, and a water injection pipe is provided on the side of the filter copper mesh near the sealing airbag.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: When the pipeline water discharge and slag removal equipment with filtration and fire suppression function is used, the fixed seat needs to move automatically downward so that the sealing plug connects with the main body of the slag removal equipment to seal the equipment, thereby automatically cutting off the gas in the pipeline. The sealing performance is improved by the expansion of the sealing airbag, thus having the function of automatically closing the pipeline. The telescopic rod is activated to drive the movable seat to move, which drives the acoustic detector to continuously detect the pipeline and equipment, helping the staff to detect faults in time, thus having the function of detecting pipelines and slag removal equipment. Water spraying is carried out to extinguish fire through the filter copper mesh and water injection pipe, thus having the function of filtration and fire suppression during the use of the pipeline water discharge and slag removal equipment.

[0016] 1. When the gas flow rate in the extraction pipeline exceeds the safety index of the equipment due to factors such as operator error and changes in internal mine pressure, and it is necessary to shut down the pipeline to prevent equipment failure, the pressure difference between the inside and outside of the pipeline causes the fixed seat to move downward and connect with the fixed groove. Then, the movement of the fixed seat drives the movable rod to move, causing the angle between the fixed seat and the movable rod to change, which in turn drives the limit rod to move, so that the sealing plug connects with the main body of the slag removal equipment, sealing the main body of the slag removal equipment and automatically cutting off the gas in the pipeline. Then, air is inflated into the sealing airbag through the air inflator, causing the sealing airbag to expand and connect with the main body of the slag removal equipment, improving the sealing performance of the main body of the slag removal equipment. Thus, during the use of the pipeline water discharge slag removal equipment, it has the function of automatically closing the pipeline.

[0017] 2. During the use of the pipeline slag remover, when the gas in the coal mine is extracted through the gas pipeline, the telescopic rod is activated to move the movable seat. The movement of the movable seat causes the pulley to move along the sliding groove. While the movable seat is moving, the acoustic detector continuously detects the gas extraction pipeline and the main body of the slag removal equipment to prevent the cracks in the gas extraction pipeline and the main body of the slag removal equipment from being overlooked by the staff. This helps the staff to detect pipeline and equipment failures in a timely manner and reduce losses. Thus, during the use of the pipeline water discharge slag removal equipment, it has the function of detecting the pipeline and slag removal equipment.

[0018] 3. During the use of the pipeline slag remover, when coal slag is drawn into the pipeline along with methane gas from the coal mine, it is filtered and blocked by a copper mesh. Then, the slag is discharged through the slag discharge valve. When high-temperature gas and sparks enter the main body of the slag remover through the extraction pipeline, they are first broken up and cooled by the copper mesh, and then water is sprayed through the water injection pipeline to extinguish the fire. Thus, the pipeline water discharge slag remover has the function of filtering and suppressing fire during use. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-8 This invention provides a technical solution: a pipeline water discharge and slag removal device with filtration and fire suppression functions, including a slag removal device body 1, a guide rod 2, and an acoustic detector 19. The guide rod 2 is connected to the top center of the slag removal device body 1, and the bottom end of the guide rod 2 is connected to a connecting seat 3 through a limiting hole 27. The bottom end of the connecting seat 3 is fixedly connected to a fixed seat 4. Movable rods 5 are rotatably connected to both sides of the fixed seat 4, and a limiting rod 6 is rotatably connected to the side of the movable rod 5 away from the fixed seat 4. A support seat 7 is sleeved on the outer wall of the limiting rod 6. A sealing plug 8 is connected to the side of the limiting rod 6 away from the movable rod 5, and a sealing airbag 9 is connected to the side of the sealing plug 8 away from the limiting rod 6. An inflation pipe 10 is connected to the limiting rod 6 through an inflation groove 28. A threaded pin 11 is fixedly connected to the bottom end of the guide rod 2, and a threaded hole 12 is opened inside the fixed seat 4 to mate with the threaded pin 11. A fixing groove 29 is opened at the bottom center of the slag removal device body 1 to mate with the fixed seat 4.

[0030] The support base 7 is symmetrically distributed about the vertical midline of the fixed base 4, and the bottom end of the support base 7 is fixedly connected to the bottom surface of the inner wall of the slag removal equipment body 1; the top end of the fixed base 4 is provided with a limiting hole 27 that connects with the guide rod 2, and the air filling pipe 10 is symmetrically distributed about the vertical midline of the fixed base 4; the side of the air filling pipe 10 away from the limiting rod 6 is connected to the slag removal equipment body 1, and the air filling pipe 10 is symmetrically distributed about the vertical midline of the slag removal equipment body 1; the limiting rod 6 and the movable rod 5 are symmetrically distributed about the vertical midline of the fixed base 4, and the center lines between the fixed base 4, the connecting base 3 and the guide rod 2 coincide with each other.

[0031] In practice, when the gas flow rate in the extraction pipeline exceeds the equipment's safety limits due to operator error or changes in internal mine pressure, requiring pipeline closure to prevent equipment malfunction, the pressure difference between the inside and outside of the pipeline causes the fixed seat 4 to move downwards, engaging with the fixed groove 29. The downward movement of the fixed seat 4 then moves the movable rod 5, changing the angle between them. This, in turn, moves the limiting rod 6 closer to the fixed seat 4, and the supporting seat 7 provides support and guidance for the limiting rod 6, ensuring the sealing plug 8 engages with the main slag removal equipment. The main body 1 of the slag removal equipment is connected to the main body 1, which automatically isolates the gas in the pipeline. Then, air is injected into the sealing airbag 9 through the air inflator 10, so that the sealing airbag 9 expands and connects with the main body 1 of the slag removal equipment, thereby improving the sealing performance of the main body 1 of the slag removal equipment. When the pipeline isolation needs to be canceled after the fault factors are eliminated, press the guide rod 2 to connect with the limiting hole 27 at the top of the fixed seat 4, then rotate the guide rod 2 to connect the threaded pin 11 with the threaded hole 12, and then pull up the guide rod 2 to move the fixed seat 4 upward, so that the pipeline is unobstructed. Thus, the pipeline slag removal equipment has the function of automatically sealing the pipeline during the use of pipeline water discharge.

[0032] See Figure 1 , Figure 2 and Figure 5It can be seen that telescopic rods 13 are installed on both sides of the top of the slag removal equipment body 1, and the top of the telescopic rods 13 are connected to the first rotating seat 24; the first rotating seat 24 is movably connected to the first connecting rod 14, and the top of the first connecting rod 14 is rotatably connected to the second connecting rod 15; the bottom of the second connecting rod 15 is connected to the second rotating seat 25, and the bottom of the second rotating seat 25 is fixedly connected to the movable seat 16; pulleys 17 are installed on both sides of the bottom of the movable seat 16, and the top of the slag removal equipment body 1 has a corresponding opening for the pulleys 17. The sliding groove 26 is connected; the top of the movable seat 16 is connected to the protective box 18, and the inside of the protective box 18 is connected to the acoustic detector 19; the acoustic detector 19 is model DUNT-930; the pulleys 17 are symmetrically distributed about the vertical midline of the movable seat 16, and the movable seat 16 is symmetrically distributed about the vertical midline of the slag removal equipment body 1; the first rotating seat 24 and the second rotating seat 25 are parallel to each other; the side of the movable seat 16 near the guide rod 2 is connected to the output end of the telescopic rod 13.

[0033] In practical implementation, during the use of the pipeline slag remover, when gas is extracted from the coal mine through the gas pipeline, the telescopic rod 13 is activated to move the movable seat 16. The movement of the movable seat 16 causes the pulley 17 to move along the sliding groove 26. When the telescopic rod 13 extends and retracts, the angle between the first connecting rod 14 and the second connecting rod 15 changes, thereby guiding and limiting the movement of the movable seat 16. When the movable seat 16 moves, the acoustic detector 19 inside the protective box 18 is activated to detect the gas extraction pipeline and the main body of the slag removal equipment 1. This prevents the gas extraction pipeline and the main body of the slag removal equipment 1 from wearing down and cracking due to long-term gas erosion and the impact of debris during long-term use, and even damage to the pipeline. This helps the staff to detect pipeline and equipment failures in time and reduce losses. Thus, during the use of the pipeline water discharge slag removal equipment, it has the function of detecting pipelines and slag removal equipment.

[0034] See Figure 2 , Figure 5 and Figure 8 It can be seen that the main body 1 of the slag removal equipment has snap-fit ​​grooves 20 on both sides, and the snap-fit ​​grooves 20 are snap-fitted to the filter copper mesh 21; a slag discharge door 22 is provided below the filter copper mesh 21, and a water injection pipe 23 is provided on the side of the filter copper mesh 21 near the sealing airbag 9; the slag discharge door 22 is connected to the main body 1 of the slag removal equipment, and the slag discharge door 22 is symmetrically distributed about the vertical center line of the main body 1 of the slag removal equipment; the water injection pipe 23 is connected to the main body 1 of the slag removal equipment, and the water injection pipe 23 is symmetrically distributed about the vertical center line of the main body 1 of the slag removal equipment.

[0035] In practical implementation, during the use of the pipeline slag remover, when the coal gas in the coal mine is extracted through the gas pipeline and coal slag is also drawn into the pipeline, the coal slag is filtered and blocked by the copper mesh 21 in the clamping groove 20. Then, the slag discharge door 22 is opened periodically to discharge the blocked coal slag out of the equipment. When high-temperature gas and sparks enter the main body 1 of the slag remover through the branch of the gas extraction pipeline, they are first broken and cooled by the copper mesh 21. Then, water is sprayed into the main body 1 of the slag remover through the water injection pipe 23 to extinguish the fire, thereby filtering and suppressing the fire. Thus, the pipeline water discharge slag remover has the function of filtering and suppressing the fire during use.

[0036] In summary, when using this pipeline water discharge and slag removal equipment with filtration and fire suppression functions, the main body 1 of the slag removal equipment is first connected to the air extraction pipeline. Then, when the gas flow rate in the pipeline exceeds the equipment's safety limits due to factors such as changes in the mine's internal gas pressure, requiring the pipeline to be shut down to prevent equipment malfunction, the fixed seat 4 automatically moves downwards, causing the sealing plug 8 to connect with the main body 1 of the slag removal equipment, sealing the equipment and automatically isolating the gas in the pipeline. The sealing airbag 9 expands to improve the sealing performance, and the threaded pin 11 connects with the threaded hole 12, thereby pulling up the guide rod 2 and causing the fixed seat 4 to move upwards, restoring the pipeline's flow. This ensures smooth operation of the pipeline water discharge and slag removal equipment. The device features automatic pipe closure. Activating the telescopic rod 13 moves the movable seat 16, causing the acoustic detector 19 to continuously monitor the pipes and equipment, helping staff detect faults promptly. The first connecting rod 14 and the second connecting rod 15 guide and limit the movement of the movable seat 16, thus enabling the device to monitor the pipes and remove slag during operation. Through the cooperation of the copper filter mesh 21 and the water injection pipe 23, the device performs water spraying for fire extinguishing and filtration / slag removal, providing a fire suppression and filtration function during operation. Content not described in detail in this specification is prior art known to those skilled in the art.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
