Description

Technical Field

[0001] The utility model relates to the technical field of gas extraction, in particular to an automatic water and slag discharge device for preventing blockage of coal mine gas extraction pipelines. Background Art

[0002] At present, in coal mines with high gas content, extraction systems are generally configured to extract coal seam gas. Due to the complex structure of the original coal seam, a certain amount of water, coal slag, gangue and other debris will enter the extraction pipeline during the extraction process. If it is not cleaned in time, it will cause siltation and blockage in the extraction pipeline, thereby affecting the extraction efficiency. In severe cases, the pipeline will be blocked, causing the negative pressure of the pipeline to increase, the load of the extraction equipment to increase, and the extraction equipment will be damaged, and gas extraction cannot be carried out, which brings major hidden dangers to production safety. To solve this problem, it is necessary to install a slag discharge device on the gas extraction pipeline to discharge the accumulated water and coal slag in the pipeline to ensure efficient gas extraction.

[0003] In the prior art, when in use, a slag discharge device is installed at one end of a pipeline. When gas passes through, the coal slag and water carried by the gas will accumulate inside the slag discharge device. When cleaning, the device is opened and cleaned.

[0004] However, in actual use, dedicated personnel are required to clean the slag regularly, which is not only time-consuming and labor-intensive, but also often causes blockage of the extraction pipe due to untimely slag discharge, seriously affecting the normal operation of the gas extraction system, thereby reducing work efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an automatic water drainage and slag discharge device for preventing blockage in coal mine gas extraction pipelines, which solves the problem that when actually using slag discharge, full-time personnel are required to clean the slag regularly, which is not only labor-intensive and time-consuming, but also often causes blockage of the extraction pipeline due to untimely slag discharge, seriously affecting the normal operation of the gas extraction system, thereby reducing work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a coal mine gas extraction pipeline anti-blocking automatic water drainage and slag discharge device, comprising an outer shell, both ends of the outer shell are connected with connecting pipes, one end of the two connecting pipes is equipped with a flange, the inner wall of the outer shell is fixedly connected with a support plate, the bottom of the support plate is connected with a discharge shell, and a slag discharge device is installed at the bottom of the discharge shell, the slag discharge device comprises a slag discharge cover, a second torsion spring, a pressure plate, a fixing bolt and a threaded base, the top of the slag discharge cover is rotatably connected to the bottom of the discharge shell, the top of the slag discharge cover is tightly pressed by the second torsion spring, the outer wall of the second torsion spring is tightly pressed by the discharge shell, the bottom of the slag discharge cover is movably connected with a threaded base, the threaded base extends to one end of the top of the slag discharge cover and is threadedly connected with a fixing bolt, the outer wall of the fixing bolt is plugged with a pressure plate, and the outer wall of the pressure plate is plugged into the inner wall of the discharge shell.

[0007] Preferably, a compression spring is pressed against the bottom of the pressure plate, a fixing block is pressed against the bottom of the compression spring, and the bottom of the fixing block is fixedly connected to the top of the slag discharge cover.

[0008] Preferably, an O-ring is inserted into the outer wall of the threaded base, and the bottom of the O-ring is pressed against the top of the slag discharge cover.

[0009] Preferably, the bottom of the shell is rotatably connected to a bottom cover, the top of the bottom cover is pressed against a first torsion spring, the outer wall of the first torsion spring is fixedly connected to the outer wall of the shell, the bottom cover is installed with a tension spring, and the top of the tension spring is installed on the outer wall of the shell.

[0010] Preferably, a mounting block is fixedly connected to the upper part of the outer wall of the shell, a sealing rubber pad is pressed against the top of the mounting block, a sealing plate is pressed against the top of the sealing rubber pad, and the outer wall of the sealing plate is fixedly connected to the top of the mounting block by bolts.

[0011] The utility model provides an automatic water drainage and slag discharge device for preventing blockage of coal mine gas extraction pipeline, which has the following beneficial effects: the automatic water drainage and slag discharge device for preventing blockage of coal mine gas extraction pipeline cooperates with a slag discharge cover, a second torsion spring and a pressure plate. When the slag discharge device is installed on the pipeline, the accumulated water and coal slag in the gas will fall into the inside of the lower shell, and as the accumulation increases, the pressure plate will squeeze the slag discharge cover, and the slag discharge cover will squeeze the second torsion spring on one side of it, so that the slag discharge cover is opened to discharge impurities such as coal slag, and after the discharge, the lower shell is closed under the action of the second torsion spring, which solves the problem that the prior art needs full-time personnel to clean slag regularly when in use, which is not only labor-intensive and time-consuming, but also often causes blockage of the extraction pipe due to untimely slag discharge, seriously affecting the normal operation of the gas extraction system, thereby reducing work efficiency.

[0012] Through the cooperation of the tension spring, the first torsion spring and the bottom cover, when the coal slag and accumulated water in the discharge shell are discharged, they will accumulate on the bottom cover, and as the accumulation is too much, the weight of the coal slag will exceed the pressure that the tension spring and the first torsion spring can withstand, so that the bottom cover will open and the coal slag and accumulated water will be discharged. After the water is drained, the bottom cover will be closed under the action of the tension spring and the first torsion spring to avoid leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] However, in actual use, dedicated personnel are required to clean the slag regularly, which is not only time-consuming and labor-intensive, but also often causes blockage of the extraction pipe due to untimely slag discharge, seriously affecting the normal operation of the gas extraction system, thereby reducing work efficiency.

[0020] In view of this, the utility model provides an automatic water drainage and slag discharge device for preventing blockage in coal mine gas extraction pipelines, which solves the problem that when slag discharge is actually used, full-time personnel are required to clean the slag regularly, which is not only labor-intensive and time-consuming, but also often causes blockage of the extraction pipeline due to untimely slag discharge, seriously affecting the normal operation of the gas extraction system, thereby reducing work efficiency.

The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0022] Embodiment 1: Figure 1-4 It can be seen that an automatic drainage and slag discharge device for preventing blockage of coal mine gas extraction pipeline comprises a shell 1, both ends of the shell 1 are connected with connecting pipes 2, one end of the two connecting pipes 2 is installed with flanges 3, the slag discharge device is connected to the pipeline by using the flange 3, the inner wall of the shell 1 is fixedly connected with a support plate 12, the bottom of the support plate 12 is connected with a discharge shell 5, the bottom of the discharge shell 5 is installed with a slag discharge device, the slag discharge device comprises a slag discharge cover 6, a second torsion spring 17, a pressure plate 10, a fixing bolt 15 and a threaded base 14, the top of the slag discharge cover 6 is rotatably connected to the bottom of the discharge shell 5, the top of the slag discharge cover 6 is tightly pressed against the second torsion spring 17, the outer wall of the second torsion spring 17 is tightly pressed against the discharge shell 5, the bottom of the slag discharge cover 6 is movably connected with a threaded base 14, the threaded base 14 extends to one end of the top of the slag discharge cover 6 and is threadedly connected with a fixing bolt 15, the outer wall of the fixing bolt 15 is plugged with a pressure plate 10, and the outer wall of the pressure plate 10 is plugged into the inner wall of the discharge shell 5;

[0023] In the specific implementation process, it is worth pointing out that, under the cooperation of the slag discharge cover 6, the second torsion spring 17 and the pressure plate 10, when the slag discharge device is installed on the pipeline, the accumulated water and coal slag in the gas will fall into the inside of the lower shell 5, and as the accumulation increases, the pressure plate 10 squeezes the slag discharge cover 6, and at the same time, the slag discharge cover 6 squeezes the second torsion spring 17 on one side thereof, opens the slag discharge cover 6, and discharges impurities such as coal slag, and after the discharge, under the action of the second torsion spring 17, the lower shell 5 is closed;

[0024] Furthermore, a compression spring 11 is pressed against the bottom of the pressure plate 10, a fixing block 13 is pressed against the bottom of the compression spring 11, and the bottom of the fixing block 13 is fixedly connected to the top of the slag discharge cover 6;

[0025] In the specific implementation process, it is worth pointing out that, under the cooperation of the compression spring 11, the pressure plate 10 and the slag discharge cover 6, when the coal slag and accumulated water accumulate on the pressure plate 10, the compression spring 11 will be squeezed, and when the weight of the coal slag on the pressure plate 10 exceeds the pressure that the compression spring 11 can withstand, the slag discharge cover 6 will be squeezed, so that when the volume of impurities in the discharge shell 5 is too large, the slag discharge cover 6 will be opened;

[0026] Furthermore, an O-ring 16 is inserted into the outer wall of the threaded base 14, and the bottom of the O-ring 16 is pressed against the top of the slag discharge cover 6;

[0028] Specifically, when using the automatic water drainage and slag discharge device for preventing blockage of the coal mine gas extraction pipeline, when installing the slag discharge device, use the flange 3 to connect it to the pipeline. When working after the connection, the coal slag and accumulated water will fall into the inside of the discharge shell 5, accumulate on the top of the pressure plate 10, and squeeze the compression spring 11. When the weight is greater than the pressure that the compression spring 11 can withstand, the threaded base 14 will move downward, and when moving, the O-ring 16 can prevent the discharge shell 5 from leaking, and when the pressure on the slag discharge cover 6 is too large, it will cause it to squeeze the second torsion spring 17, thereby opening the slag discharge cover 6 and discharging the coal slag. After the discharge, under the action of the second torsion spring 17, the slag discharge cover 6 closes the discharge shell 5 to avoid leakage when the gas passes through.

[0030] In the specific implementation process, it is worth pointing out that, with the cooperation of the bottom cover 7, the first torsion spring 8 and the tension spring 9, when the coal slag and the accumulated water in the discharge shell 5 are discharged onto the bottom cover 7, the pressure of the accumulated coal slag will exceed the weight that the tension spring 9 and the first torsion spring 8 can bear, so that they open and discharge the coal slag and the accumulated water;

[0031] Furthermore, a mounting block 18 is fixedly connected to the upper part of the outer wall of the housing 1, a sealing pad 19 is pressed against the top of the mounting block 18, a sealing plate 4 is pressed against the top of the sealing pad 19, and the outer wall of the sealing plate 4 is fixedly connected to the top of the mounting block 18 by bolts;

[0032] In the specific implementation process, it is worth pointing out that, with the cooperation of the mounting block 18, the sealing plate 4 and the sealing rubber pad 19, when the slag discharge device is overhauled, the sealing plate 4 is opened, and after the overhaul, it is fixed with bolts, and the sealing rubber pad 19 is squeezed so that it will not leak after closing;

[0033] Specifically, on the basis of the above-mentioned embodiment, after the slag discharge device is installed on the pipeline, the coal slag is discharged through the slag discharge cover 6, and the impurities can also be discharged by the bottom cover 7 to avoid affecting its work during the slag discharge. After the slag discharge is carried out, the sealing plate 4 is fixed with bolts so that the sealing gasket 19 seals the outer shell 1.
