Description

Technical Field

[0001] This utility model belongs to the field of gas extraction technology, specifically relating to a gas extraction pipe slag storage and discharge system. Background Technology

[0002] During tunnel excavation, due to local coal seam variations, the tunnel cannot maintain a uniform slope. Consequently, the height of the gas drainage pipeline laid inside the tunnel may be lower than that at both ends in certain areas. Water easily accumulates inside these drainage pipelines, and if it is not drained promptly, it will affect the negative pressure and drainage efficiency. Therefore, an automatic water drainer is usually connected to the bottom of the drainage pipeline to drain the accumulated water. However, due to severe slag accumulation inside the drainage pipeline, the effectiveness of the automatic water drainer is affected. Therefore, a slag discharge box is installed at the connection between the automatic water drainer and the drainage pipeline. When slag has accumulated to a certain level, the slag inside the slag discharge box is discharged.

[0003] However, most slag discharge boxes are currently made of welded iron sheets, and the height of the coal slag inside cannot be directly observed. When too much coal slag accumulates or is used for a long time, it can easily block the water outlet on the slag discharge box, making it difficult for on-site operators to detect and maintain. In severe cases, it can also cause the drainage pipe to be blocked by water accumulation, affecting the drainage of gas. Utility Model Content

[0004] This utility model provides a slag storage and discharge system with a gas extraction pipe, which aims to solve the problem that it is not easy to detect and maintain the slag discharge box of the gas extraction pipeline in the casserole when it is blocked.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a slag storage and discharge system with a slag extraction and discharge pipe, comprising:

[0006] A slag discharge box, the top of which is connected to an inlet pipe for connecting to a drain pipe, and a first control valve is provided on the inlet pipe;

[0007] There are two overflow pipes, both of which are connected to the middle of the slag discharge box. The two overflow pipes are at different heights on the slag discharge box. The liquid outlet of the overflow pipe is used to connect to the automatic water discharge device.

[0008] A slag discharge pipe is connected to the bottom of the slag discharge box and is used to discharge the coal slag inside the slag discharge box. A second control valve is installed on the slag discharge pipe.

[0009] In one possible implementation, mounting sleeves for installing the overflow pipe are fixedly installed on the side walls of the slag discharge box, and the overflow pipe is detachably installed on the mounting sleeves.

[0010] In one possible implementation, a filter head is detachably connected to the end of the overflow pipe, and when the overflow pipe is installed on the slag discharge box, the filter head is located inside the slag discharge box.

[0011] In one possible implementation, the end of the filter head is provided with a connection portion that is threadedly connected to the overflow pipe, and the connection portion can abut against the outer side wall of the slag discharge box to limit the installation position of the overflow pipe.

[0012] In one possible implementation, a sealing ring is fitted on the outer side of the overflow pipe, and a limiting platform for limiting the sealing ring is provided at the end of the overflow pipe. A tightening sleeve for pressing the sealing ring against the limiting platform is threaded onto the mounting sleeve.

[0013] In one possible implementation, the clamping sleeve includes a threaded portion that is threadedly connected to the mounting sleeve, and the end of the threaded portion is provided with a guide portion that slides in cooperation with the inner wall of the mounting sleeve.

[0014] In one possible implementation, a guide ring is slidably disposed on the outer side of the overflow pipe, the guide ring being located on the side of the sealing ring away from the limiting platform.

[0015] In one possible implementation, a plurality of filter holes are provided on the sidewall of the filter head, the length direction of the filter holes is arranged along the length direction of the filter head, and the plurality of filter holes are evenly spaced along the circumference of the filter head.

[0016] The solution shown in this application, compared with the prior art, includes a slag discharge box installed below the extraction pipe. A liquid inlet pipe is connected to the top of the slag discharge box, and a first control valve is installed on the liquid inlet pipe. Two overflow pipes are connected to the middle of the slag discharge box, located on opposite sides of the box at different heights. A slag discharge pipe is connected to the bottom of the slag discharge box. In use, the liquid inside the extraction pipe can be discharged into the slag discharge box by opening the first control valve. The coal slag inside the liquid settles inside the slag discharge box, and the coal slag can be discharged by opening the second control valve on the slag discharge pipe. The liquid inside the slag discharge box can overflow from the lower overflow pipe and flow into the water discharge device. When the coal slag height inside the slag discharge box exceeds the lower overflow pipe or the lower overflow pipe is blocked, the liquid inside the slag discharge box can overflow from the upper overflow pipe. When operators are on-site for inspection or monitoring, they can promptly detect any abnormalities after the liquid is discharged from the automatic drain valve corresponding to the upper overflow pipe. This allows them to carry out slag removal operations and unclog and maintain the lower overflow pipe, preventing the liquid from failing to drain from the slag box and affecting subsequent gas extraction.

[0021] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please refer to the following: Figure 1 and Figure 2 The present invention provides a slag storage and discharge system using a slag extraction and discharge pipe. The system includes a slag discharge box 1, an overflow pipe 3, and a slag discharge pipe 4. The top of the slag discharge box 1 is connected to an inlet pipe 2 for connecting to the extraction and discharge pipe, and a first control valve 21 is installed on the inlet pipe 2. There are two overflow pipes 3, both connected to the middle of the slag discharge box 1, and the two overflow pipes 3 are at different heights on the slag discharge box 1. The outlet end of the overflow pipe 3 is connected to an automatic water discharge device. The slag discharge pipe 4 is connected to the bottom of the slag discharge box 1 and is used to discharge the coal slag inside the slag discharge box 1. A second control valve 41 is installed on the slag discharge pipe 4.

[0023] The slag storage and discharge system provided in this embodiment, compared with the prior art, features a slag discharge box 1 installed below the extraction pipe. A liquid inlet pipe 2 is connected to the top of the slag discharge box 1, and a first control valve 21 is installed on the liquid inlet pipe 2. Two overflow pipes 3 are connected to the middle of the slag discharge box 1, located on opposite sides of the box with different heights. A slag discharge pipe 4 is connected to the bottom of the slag discharge box 1. In use, the liquid inside the extraction pipe can be discharged into the slag discharge box 1 by opening the first control valve 21. The slag inside the liquid settles inside the slag discharge box 1, and the slag can be discharged by opening the second control valve 41 on the slag discharge pipe 4. The liquid inside the slag discharge box 1 overflows from the overflow pipes 3 below and flows into the drainer. When the slag inside the slag discharge box 1 exceeds the height of the lowest overflow pipe 3, or when the lower overflow pipe 3 becomes blocked, the liquid inside the slag discharge box 1 can overflow from the upper overflow pipe 3. During on-site inspections, operators can promptly detect any abnormalities when liquid is discharged from the automatic drain corresponding to the upper overflow pipe 3, allowing for timely slag discharge operations and unblocking and maintenance of the lower overflow pipe 3. This prevents liquid from failing to drain from the slag discharge box 1, which could affect subsequent gas extraction.

[0024] Specifically, in this embodiment, the bottom of the slag discharge box 1 is a conical structure, and the slag discharge pipe 4 is connected to the bottom of the conical structure.

[0025] Specifically, in this embodiment, a third control valve is installed on each of the two overflow pipes 3, and each of the two overflow pipes 3 is individually connected to an automatic water discharge device.

[0026] In some embodiments, the slag discharge box 1 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2 Each side wall of the slag discharge box 1 is fixedly equipped with an installation sleeve 5 for installing an overflow pipe 3. The overflow pipe 3 is detachably installed on the installation sleeve 5. The installation sleeve 5 is fixedly installed on the outer side wall of the slag discharge box 1, and the installation sleeve 5 is welded and sealed to the side wall of the slag discharge box 1. The overflow pipe 3 is inserted into the installation sleeve 5, and after the overflow pipe 3 is inserted into the installation sleeve 5, it is sealed and connected to the installation sleeve 5. In this embodiment, by detachably installing the overflow pipe 3 onto the installation sleeve 5, the overflow pipe 3 can be easily removed from the slag discharge box 1, thereby facilitating subsequent maintenance.

[0027] In some embodiments, the overflow pipe 3 described above can be as follows: Figure 1 , Figure 2 The structure shown. See also... Figure 1 , Figure 2A filter head 6 is detachably connected to the end of the overflow pipe 3. When the overflow pipe 3 is installed on the slag discharge box 1, the filter head 6 is located inside the slag discharge box 1. The filter head 6 is detachably installed at the end of the overflow pipe 3 and is sealed to the overflow pipe 3. During use, the liquid inside the slag discharge box 1 can be filtered through the filter head 6, which can control the entry of larger coal slag into the automatic water discharge device at the rear, thus preventing blockage of the automatic water discharge device.

[0028] Specifically, in this embodiment, a filter head 6 is detachably installed at the end of the overflow pipe 3. This allows the filter head 6 to be removed and cleaned if it becomes clogged and unusable. Simultaneously, the filter head 6 can be replaced individually to ensure proper liquid flow. This makes the operation simpler and more convenient.

[0029] In some embodiments, the filter head 6 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The filter head 6 has a connecting part 61 at its end that is threadedly connected to the overflow pipe 3. The connecting part 61 can abut against the outer wall of the slag discharge box 1 to limit the installation position of the overflow pipe 3. The connecting part 61 is fixedly connected to the end of the filter head 6, and the outer diameter of the connecting part 61 is larger than the outer diameter of the filter head 6. A through hole is provided on the side wall of the slag discharge box 1 to slide with the filter head 6. The inner diameter of the mounting sleeve 5 is larger than the inner diameter of the through hole. Thus, when the filter head 6 is installed on the slag discharge box 1, the connecting part 61 can abut against the outer wall of the slag discharge box 1. This limits the installation position of the filter head 6 and the overflow pipe 3 on the slag discharge box 1, facilitating the subsequent installation of the overflow pipe 3 on the slag discharge box 1.

[0030] Specifically, in this embodiment, an external thread is provided at the end of the overflow pipe 3, and a threaded hole is provided at the liquid outlet end of the filter head 6, so that the filter head 6 can be installed at the end of the overflow pipe 3. Then, the filter head 6 and the overflow pipe 3 are placed inside the mounting sleeve 5. The connecting part 61 at the end of the filter head 6 abuts against the outer wall of the slag discharge box 1. Finally, the overflow pipe is fixedly sealed inside the mounting sleeve 5. The structure is simple and easy to install after later maintenance.

[0031] Preferably, in this embodiment, the outer diameter of the connecting part 61 is larger than the outer diameter of the filter head 6, which can enhance the strength of the connection between the filter head 6 and the overflow pipe 3.

[0032] In some embodiments, the overflow pipe 3 described above can be as follows: Figure 2 The structure shown. See also Figure 2An overflow pipe 3 has a sealing ring 31 fitted on its outer side, and a limiting platform 32 for limiting the sealing ring 31 is provided at the end of the overflow pipe 3. A tightening sleeve 7 for pressing the sealing ring 31 against the limiting platform 32 is threaded onto the mounting sleeve 5. The limiting platform 32 is provided at the end of the overflow pipe 3, and the outer diameter of the limiting platform 32 is larger than the outer diameter of the overflow pipe 3. The sealing ring 31 is fitted on the outer side of the overflow pipe 3, and one end face abuts against the limiting platform 32. The tightening sleeve 7 is fitted on the outer side of the overflow pipe 3, and the tightening sleeve 7 is threadedly connected to the mounting sleeve 5. The tightening sleeve 7 can be moved towards the sealing ring 31 by rotating it, thereby compressing and deforming the sealing ring 31. After the sealing ring 31 is compressed, the inner ring abuts against the outer wall of the overflow pipe 3, and the outer ring abuts against the inner wall of the mounting sleeve 5, thereby achieving a seal between the mounting sleeve 5 and the overflow pipe 3.

[0033] Optionally, in this embodiment, after the tightening sleeve 7 is tightened onto the mounting sleeve 5, the tightening sleeve 7 will push the overflow pipe 3 to move closer to the inside of the slag discharge box 1, so that the connecting part 61 on the filter head 6 abuts against the outer wall of the slag discharge box 1, thereby fixing the overflow pipe 3 on the slag discharge box 1.

[0034] In some embodiments, the aforementioned tightening sleeve 7 can be adopted as follows: Figure 2 The structure shown. See also Figure 2 The tightening sleeve 7 includes a threaded portion 71 that is threadedly connected to the mounting sleeve 5. The end of the threaded portion 71 has a guide portion 72 that slides within the inner wall of the mounting sleeve 5. A threaded hole, threaded to the threaded portion 71, is located at the end of the mounting sleeve 5, and a guide hole, slidingly engaged with the guide portion 72, is located in the middle of the mounting sleeve 5. The guide portion 72 and the guide hole guide the installation position of the tightening sleeve 7. Simultaneously, the overflow pipe 3 is slidably disposed inside the tightening sleeve 7, and the position of the overflow pipe 3 is guided by the position of the tightening sleeve 7. This improves the stability of the overflow pipe 3 after it is installed inside the mounting sleeve 5.

[0035] In some embodiments, the overflow pipe 3 described above can be as follows: Figure 2 The structure shown. See also Figure 2 A guide ring 33 is slidably disposed on the outer side of the overflow pipe 3, and the guide ring 33 is located on the side of the sealing ring 31 away from the limiting platform 32. The sealing ring 31 is located between the guide ring 33 and the limiting platform 32. When the tightening sleeve 7 is installed on the mounting sleeve 5, the end of the tightening sleeve 7 abuts against the guide ring 33, which can reduce damage to the sealing ring 31.

[0036] Specifically, if the tightening sleeve 7 acts directly on the sealing ring 31, it may damage the sealing ring 31 when the tightening sleeve 7 is rotated. However, by setting the guide ring 33, the tightening sleeve 7 can rotate relative to the guide ring 33, which can prevent the tightening sleeve 7 from acting directly on the sealing ring 31 and improve the service life of the sealing ring 31.

[0037] Specifically, in this embodiment, the sealing ring 31 is made of rubber or polyurethane material and has a certain elastic deformation performance.

[0038] In some embodiments, the filter head 6 described above can be as follows: Figure 2 The structure shown. See also Figure 2 The filter head 6 has multiple filter holes on its sidewall, with the length of the filter head 6 aligned with its length and evenly spaced around its circumference. The length of the filter holes is also aligned with the axis of the filter head 6; however, when the filter head 6 is installed on the slag discharge box 1, its axis is horizontal. The elongated filter holes increase the water intake of the filter head 6 and allow larger coal slag to be filtered out. Furthermore, the multiple filter holes prevent water from entering through any single clogging hole, thus extending the service life of the filter head 6.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
