Technical Field

[0001] This application relates to the field of coal mine dust suppression technology, and in particular to a water curtain water purification device. Background Technology

[0002] During coal mining, the working face generates a large amount of coal dust and harmful gases. Water curtains can purify these pollutants and protect miners' lives. Currently, underground water curtains are directly connected to the underground water supply pipeline and can be used normally by simply opening the valve. However, impurities in the water supply pipeline may cause blockages in the nozzles that form the water curtain. To address this, the inventors have proposed a water curtain water purification device. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0029] In related technologies, during coal mining, the working face generates a large amount of coal dust and harmful gases. Water curtains can purify these pollutants and protect the lives of miners. Currently, underground water curtains are directly connected to the underground water supply pipeline, and can be used normally by simply opening the valve. However, because the water in the supply pipeline contains impurities, it may cause blockage of the nozzles that form the water curtain.

[0030] This embodiment provides a water curtain water purification device that can filter the water flowing to the nozzle to reduce the probability of nozzle clogging.

[0031] Please see Figures 1-3 In this embodiment, a water curtain water purification device includes a pipe 10, a support ring 20, and a filter screen 30. The pipe 10 has an inlet 11 and an outlet 12, and a sealing cap 13 is screwed onto the end of the pipe 10. The support ring 20 is fixedly connected to the sealing cap 13, and a sealing ring 22 is sleeved on the outside of the support ring 20. A pressure ring 23 is screwed onto the inside of the support ring 20. The filter screen 30 is pressed into the inside of the support ring 20 by the pressure ring 23. Water flowing into the inside of the pipe 10 through the inlet 11 passes through the filter screen 30 and flows out through the outlet 12.

[0032] Using the technical solution of this embodiment, a filter screen 30 is installed inside the pipe 10 between the water inlet 11 and the water outlet 12, which can filter the water quality and reduce the probability of nozzle clogging. The filter screen 30 can be taken out by removing the sealing cover 13, which facilitates the replacement of the filter screen 30.

[0033] In this embodiment, the pipe fitting 10 is constructed as a circular tube, with the left end of the pipe fitting 10 closed and the right end open. The sealing cap 13 is screwed onto the right end of the pipe fitting 10, thereby forming a closed space inside the pipe fitting 10. The inlet 11 and the outlet 12 are both fixedly connected to the pipe fitting 10, and the axes of the inlet 11 and the outlet 12 are both arranged perpendicular to the axis of the pipe fitting 10. As an example, the axes of the inlet 11 and the outlet 12 are both arranged radially along the pipe fitting 10, and the inlet 11 and the outlet 12 are symmetrical at the left and right ends of the pipe fitting 10.

[0034] It should be noted that the inlet 11 is connected to the underground water supply pipeline of the coal mine, and the outlet 12 is connected to the nozzle that forms the water curtain. The water in the water supply pipeline flows into the pipe fitting 10 through the inlet 11 and finally flows out to the nozzle through the outlet 12.

[0035] In this embodiment, the support ring 20 is constructed in a circular shape, with the left end of the support ring 20 open and the right end closed. A connecting rod 21 is fixedly connected between the right end of the support ring 20 and the sealing cover 13, and the connecting rod 21 is arranged at the axis of the pipe fitting 10. Multiple water-permeable holes 24 are provided at the right end of the support ring 20, and the multiple water-permeable holes 24 are evenly distributed along the circumference of the support ring 20. An annular groove is provided on the outer wall of the support ring 20, and the groove is coaxially arranged with the support ring 20. The sealing ring 22 is engaged in the groove, and the outer wall of the sealing ring 22 abuts against the inner wall of the pipe fitting 10. The sealing ring 22 is used to form a sealed connection between the outer wall of the support ring 20 and the inner wall of the pipe fitting 10.

[0036] In addition, the pressure ring 23 is constructed in a ring shape and is screwed into the interior of the support ring 20 from the left end of the support ring 20. The filter screen 30 is constructed in a circular shape and is pressed between the pressure ring 23 and the right end plate of the support ring 20.

[0037] It should be noted that the connecting rod 21 connects the support ring 20 and the sealing cover 13 into an integral structure. After the sealing cover 13 is screwed onto the right end of the pipe fitting 10, the support ring 20 is placed inside the pipe fitting 10 and is located between the water inlet 11 and the water outlet 12. The water flowing into the pipe fitting 10 through the water inlet 11 passes through the filter screen 30 and the water permeable hole 24 in sequence and flows into the pipe fitting 10 on the right side of the support ring 20, and finally flows to the nozzle through the water outlet 12.

[0038] It should be understood that in this embodiment, a filter screen 30 is provided between the water inlet 11 and the water outlet 12 to filter the water flowing to the nozzle, thereby reducing the probability of the nozzle being clogged. By fixing the filter screen 30 to the support ring 20 and fixing the support ring 20 to the sealing cover 13, the support ring 20 and the filter screen 30 can be moved out simultaneously when the sealing cover 13 is removed, which facilitates the cleaning or replacement of the filter screen 30.

[0039] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
