Description

Technical Field

[0001] The utility model relates to a water drainer, in particular to a drainage and slag discharging device of a water drainer, belonging to the technical field of gas drainage. Background Technique

[0002] Gas drainage is an essential production process in the production process of high-gas mines in China. The quality of its drainage effect affects coal production safety and production efficiency. During gas drainage, water and coal slag in the borehole will enter the gas drainage pipeline together with the gas mixture and accumulate in the pipeline, which will greatly reduce the gas drainage efficiency. Therefore, to ensure the drainage efficiency, a device is needed to discharge water and coal slag in the pipeline.

[0003] However, during the process of draining water and coal slag, since coal slag is likely to accumulate at the drainage and slag discharging port, the drainage port seal is not tight, which is likely to cause leakage in the negative pressure system, resulting in a decrease in the drainage negative pressure and a reduction in the drainage efficiency. Currently, the main reason for the leakage is that both the end face of the water outlet of the water discharging and slag discharging system and the water outlet cover plate are flat surfaces. When the water outlet cover plate is closed, coal slag is easily caught between the two flat surfaces, resulting in the sealing surface being unable to be completely sealed. Therefore, a drainage and slag discharging device of a water drainer is proposed in the application. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drainage and slag discharging device of a water drainer to solve the above problems. The end of the water inlet pipe close to the water drainer cylinder body and the end of the front end of the drainage port far from the rear end of the drainage port are subjected to conical R chamfering treatment. Instead of choosing a surface-to-surface contact design, the contact surface between the water pipe end face and the cover plate becomes smaller, and coal slag is not easily caught in it, thereby ensuring the sealing performance of the water pipe end cover. At the same time, a differential pressure sensor is arranged on each water drainer end cover to monitor the pressure difference value in the water drainer, and the conductivity between the drainage port end cover and the front end of the drainage port is monitored to determine whether the drainage port is closed, thereby achieving the effect of preventing leakage.

[0005] The utility model realizes the above purpose through the following technical solutions. A drainage and slag discharging device of a water drainer includes a water drainer end cover and a water drainer cylinder body.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] An embodiment of the present invention discloses a water drainer and slag discharge device, according to the attached Figure 1-7 As shown, it includes a water drainer end cover 1 and a water drainer cylinder body 15. The water drainer end cover 1 is installed on the top of the water drainer cylinder body 15, and the water drainer end cover 1 and the water drainer cylinder body 15 are connected to the gas drainage pipe 34. A water inlet pipe 28 and a gas connection pipe 32 are respectively installed on the side of the water drainer cylinder body 15 and the outside of the gas drainage pipe 34, and the water inlet pipe 28 and the gas connection pipe 32 are connected. A slag discharge port 11 and a rear end of the drain port 16 are provided on the outside of the water drainer cylinder body 15, and a guide rod 6 and a guide sleeve 5 are arranged inside the water drainer cylinder body 15, and a float 7 is movably sleeved outside the guide sleeve 5;

[0026] A two-position three-way reversing valve 35 and a differential pressure sensor 31 are installed on the water drainer end cover 1. A first connecting pipe 351, a second connecting pipe 352, a third connecting pipe 353, a fourth connecting pipe 354 and a fifth connecting pipe 355 are arranged outside the two-position three-way reversing valve 35. The bottom end of the second connecting pipe 352 extends into the water drainer cylinder body 15 through the water drainer end cover 1. The third connecting pipe 353 is connected to the gas connection pipe 32. A reversing valve contact 33 is also installed at the bottom of the two-position three-way reversing valve 35. The bottom end of the reversing valve contact 33 extends into the water drainer cylinder body 15 through the water drainer end cover 1, and the reversing valve contact 33 is above the float 7.

[0027] When the two-position three-way reversing valve 35 is in the initial position, the fifth connecting pipe 355, the third connecting pipe 353 and the second connecting pipe 352 are connected, and the first connecting pipe 351 is in a disconnected state. Since the pipeline is in a negative pressure state, the drain port end cover 23 is in a pressed state and isolated from the outside air. Since the third connecting pipe 353 and the second connecting pipe 352 are connected, it plays a role of negative pressure balance, enabling the water inlet end cover 25 to be freely opened. The coal slag, water and gas in the negative pressure-drained gas drainage pipe 34 can freely enter the inner cavity of the water drainer through the water inlet end cover 25. As the water level rises, the float 7 moves upward on the guide sleeve 5. When it moves to a certain extent, the upper part of the float 7 contacts the upper guide cover 4, driving the guide sleeve 5 to move upward together. When it moves to a certain position, the upper guide cover 4 contacts the reversing valve contact 33 and pushes it upward;

[0028] When it is lifted to a certain position, the position of the two-way three-position reversing valve 35 is switched from the fifth connecting pipe 355 to the water inlet pipe 28. At this time, the fifth connecting pipe 355 and the third connecting pipe 353 are disconnected, and the first connecting pipe 351 and the second connecting pipe 352 are opened. Since the first connecting pipe 351 and the second connecting pipe 352 are connected, the inner cavity of the water drainer is communicated with the atmosphere and is in a positive pressure state. Since the inside of the water inlet pipe 28 is in a negative pressure state at this time, it will cause the water inlet end cover 25 to close, so that the inner cavity of the water drainer is in a stable positive pressure state, and the drain port end cover 23 is in a freely open state. The water and cinder in the inner cavity will be discharged from the front end 19 of the drain port. As the water level in the cavity drops, the float 7 also drops. When the float 7 drops to the bottom and contacts the guiding lower retaining ring 14, it will drive the guiding sleeve 5 to drop. The position of the two-way three-position reversing valve 35 is switched from the water inlet pipe 28 position to the fifth connecting pipe 355 position. The third connecting pipe 353 and the second connecting pipe 352 are communicated, and the first connecting pipe 351 and the second connecting pipe 352. In this state, the previous cycle action is repeated.

[0029] Further, a first flange 3 is provided on the outer side of the top of the water drainer cylinder body 15. The water drainer end cover 1 is connected to the water drainer cylinder body 15 through the first flange 3, and a first gasket 2 is provided between the water drainer end cover 1 and the first flange 3.

[0030] Further, a fixed support 13 is fixedly installed between the bottom end of the guide rod 6 and the inner bottom wall of the water drainer cylinder body 15. The guide sleeve 5 is movably sleeved on the outer side of the guide rod 6. The top end and the bottom end of the guide sleeve 5 are respectively fixedly connected with an upper guide cover 4 and a guiding lower retaining ring 14.

[0031] Further, a second flange 8 is fixedly sleeved at the end of the slag discharge port 11. The second flange 8 is connected with a slag discharge end cover 10, and a second gasket 9 is provided between the second flange 8 and the slag discharge end cover 10.

[0032] Further, a water drainer base 12 is fixedly installed at the bottom of the water drainer cylinder body 15. Third flanges 29 are provided at the connection parts of the water inlet pipe 28 and the gas connection pipe 32, and a third gasket 30 is provided between the two third flanges 29.

[0033] Further, one end of the rear end 16 of the drain port away from the water drainer cylinder body 15 is connected with the front end 19 of the drain port. A connecting sleeve 17 is sleeved at the connection part between the rear end 16 of the drain port and the front end 19 of the drain port, and a wire terminal 18 is connected to the outside of the front end 19 of the drain port.

[0034] Specifically disclosed, a end cover bracket 24 is fixedly installed at the top outside the front end 19 of the drain opening, and a drain opening end cover 23 is rotatably arranged at the end of the end cover bracket 24. A drain opening gasket 22 and a conductive rubber ring 21 are arranged on the side of the drain opening end cover 23, and the conductive rubber ring 21 is embedded in the drain opening gasket 22. The side of the drain opening end cover 23 abuts against the front end 19 of the drain opening through the conductive rubber ring 21.

[0035] Furthermore, an end cover terminal 20 is embedded in the drain opening end cover 23, and the end of the end cover terminal 20 is connected to the conductive rubber ring 21.

[0036] Furthermore, the end of the water inlet pipe 28 extends towards the inside of the drainer cylinder body 15 and is fixedly connected with an end cover fixing bracket 27. An inlet port end cover 25 is rotatably arranged at the end of the end cover fixing bracket 27. An inlet port gasket 26 is arranged on the side of the inlet port end cover 25, and the inlet port end cover 25 abuts tightly against the end of the water inlet pipe 28 through the inlet port gasket 26.

[0037] The end of the water inlet pipe 28 close to the drainer cylinder body 15 and the end of the front end 19 of the drain opening far from the rear end 16 of the drain opening are subjected to a tapered R chamfering treatment. The surface-to-surface contact design is not selected, resulting in a smaller contact surface between the water pipe end face and the cover plate, and it is not easy for cinder to be clamped in it, thus ensuring the sealing performance of the water pipe end cover. At the same time, a differential pressure sensor 31 is arranged on each drainer end cover 1 to monitor the pressure difference value inside the drainer, and the conductivity between the drain opening end cover 23 and the front end 19 of the drain opening is monitored to determine whether the drain opening is closed, thereby achieving the effect of preventing leakage.

This narrative way of the specification is only for clarity. Those skilled in the art should regard 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.
