Description

Technical Field

[0001] This utility model belongs to the technical field of dust suppression equipment for mining, and in particular relates to a self-cleaning nozzle. Background Technology

[0002] The coal dust generated by the coal mining machine results in a large amount of dust in the underground coal mining area, requiring dust suppression spraying during operations.

[0003] Although the hydraulic support comes with its own nozzles, the spray range is small and cannot cover the working area, resulting in poor dust suppression. The underground water contains a high concentration of impurities, making the nozzles prone to clogging. Because the nozzles are installed at a high position, workers must stand on the cable tray to replace them when clogging occurs, posing a safety hazard.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0011] According to the self-cleaning nozzle of this utility model, the water inlet pipe is connected to the box cover.

[0012] According to the self-cleaning nozzle of this utility model, an impeller is provided inside the drain pipe.

[0013] According to the self-cleaning nozzle of this utility model, a baffle is provided inside the drain pipe, and the impeller is rotatably mounted on the baffle; the baffle is also provided with multiple water passage holes.

[0014] According to the self-cleaning nozzle of this utility model, both the impeller and the water inlet pipe are made of plastic.

[0015] According to the self-cleaning nozzle of this utility model, a flow meter is also provided on the water inlet pipe; the flow meter is configured to monitor the water flow rate in the water inlet pipe and to determine the blockage status by the change in the water flow rate.

[0016] In summary, this invention fills the water storage box with water through the inlet pipe, increasing the pressure inside the box. Water mist is then sprayed out from various nozzles in different directions to suppress dust, resulting in a large dust suppression coverage area. Each outlet is equipped with a filter screen, making the nozzles less prone to clogging. Furthermore, the cover can be opened periodically to flush the water through the drain pipe and remove dirt, further reducing the risk of clogging. Attached Figure Description

[0021] See Figure 1 and Figure 2 This utility model provides a self-cleaning nozzle, including a water storage box 1, which is connected to a water inlet pipe 2; the side wall of the water storage box 1 is provided with multiple water outlets, each water outlet is equipped with a nozzle 11; and a filter screen 12 is provided at each water outlet.

[0022] A drain pipe 13 is connected to the center of the water storage box 1, and a cap 15 is connected to the end of the drain pipe 13.

[0023] This invention fills the water storage box 1 with water through the inlet pipe 2, increasing the pressure inside the water storage box 1. Water mist is then sprayed out from each nozzle 11 in different directions to suppress dust, covering a large area. Each outlet is equipped with a filter screen 12 to prevent the nozzles 11 from clogging. Simultaneously, the cover 15 can be opened periodically to flush the water through the drain pipe 13, removing dirt and further reducing the risk of clogging.

[0024] In one embodiment, the water storage box 1 of this invention is disc-shaped, with multiple nozzles 11 evenly arranged around the side wall of the water storage box 1. The water spray direction is uniform, and the coverage area is large.

[0025] Furthermore, the water inlet pipe 2 is connected to the side wall of the water storage box 1; its overall thickness is small, allowing it to extend into narrow spaces.

[0026] As one embodiment, the water storage box 1 of this utility model includes a box body and a box cover; a plurality of nozzles 11 are arranged around the outer wall of the box body, and the drain pipe 13 is connected to the center of the box body; the box cover is screwed to the box body; the box cover can be opened to clean the dirt inside the box body.

[0027] Furthermore, the water inlet pipe 2 is connected to the box cover, so that the nozzles 11 can be evenly distributed on the outer wall of the box.

[0028] As one embodiment, the drain pipe 13 of this utility model is provided with an impeller 3; when draining, the water washes the impeller 3 to make it rotate, thereby making the water in the water storage box 1 form a swirling flow, which has a certain scouring effect on the inner wall and promotes the discharge of dirt.

[0029] Furthermore, the drain pipe 13 is provided with a baffle 14, and the impeller 3 is rotatably mounted on the baffle 14; the baffle 14 is also provided with a plurality of water passage holes; when draining, water is dispersed and sprayed out from the water passage holes, which has a certain dust suppression effect.

[0030] Optionally, both the impeller 3 and the water inlet pipe 2 are made of plastic, making them lightweight.

[0031] See Figure 3 As one embodiment, a flow meter 4 is also provided on the water inlet pipe 2; the flow meter 4 is configured to monitor the water flow rate in the water inlet pipe 2 and to determine the blockage status by the change in the water flow rate.

[0032] As one implementation method, when a significant decrease in the flow rate of the water inlet pipe 2 is detected, it can be determined that the blockage is severe and needs to be cleaned in time.

[0033] Optionally, those skilled in the art can also determine the threshold value of the water flow rate when the inlet pipe 2 is working normally through multiple tests. When the water flow rate is lower than this threshold, it is determined to be a blockage and needs to be addressed.

[0034] Furthermore, those skilled in the art can periodically test the water flow rate of the self-cleaning nozzle of this utility model, determine its blockage status based on the test results, and select the self-cleaning nozzles that need to be cleaned to ensure smooth operation downhole.

[0035] During dust suppression operations, the water inlet pipe 2 can be held by hand and the water storage box 1 extended into the dust-generating area for dust suppression. It is easy to move and covers a large dust suppression area. Alternatively, the water inlet pipe 2 can be fixed to equipment in the dust-generating area for dust suppression operations. The fixing point can be flexibly varied.

[0036] In summary, this utility model provides a self-cleaning nozzle. Water is filled into the water storage box through the inlet pipe, increasing the pressure inside the water storage box. Water mist is then sprayed out from each nozzle in different directions to suppress dust, covering a large dust suppression area. Each outlet is equipped with a filter screen, making the nozzles less prone to clogging. Furthermore, the cover can be opened periodically to flush the nozzle with water through the drain pipe, removing dirt and further reducing the risk of clogging.

[0037] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
