[0001] Embodiments of the present disclosure relate to the technical field of ejectors, and more particularly, to a self-cleaning and dust-removing ejector. Background Art
[0002] In application scenarios such as mines, mine shafts, and construction projects, spraying of drugs or water is often carried out. The liquid is impacted by the mixed gas flow of air and liquid to be atomized. The atomized liquid can have a greater adhesion rate, enabling the liquid to cover a larger area. At the same time, through the mixing of compressed gas and liquid, the atomized liquid can have greater kinetic energy, achieving better effects during cleaning and dust reduction.
[0003] Most existing two-fluid nozzles work by simultaneously introducing gas and liquid into the nozzle interior. The gas and liquid mix inside the nozzle and then are ejected. The air flow impacts the liquid to atomize it. However, due to the small size of the nozzles on the nozzle head, when there is dust, debris, or lumps in the liquid used, the nozzles on the nozzle head are prone to clogging. The clogged nozzles of existing two-fluid nozzles usually need to be disassembled for cleaning. Summary of the Invention

[0022] As Figures 1 to 6 shown, it shows a self-cleaning and dust-removing injector in an embodiment of the present disclosure, which includes a valve body seat 1, a nozzle 4, an adjustment pipe 6, an adjustment mechanism, and a cleaning needle 7. Gas inlets 2 and liquid inlets 3 are respectively arranged on both sides of the valve body seat 1. The nozzle 4 is detachably connected to the valve body seat 1. A plurality of spray openings 5 are circumferentially arranged on the nozzle 4, and the spray openings 5 are communicated with the inside of the valve body seat 1. The adjustment pipe 6 is fixedly connected to the valve body seat 1, and the adjustment pipe 6 is communicated with the inside of the valve body seat 1. The adjustment pipe 6 is arranged opposite to the nozzle 4. The adjustment mechanism is slidably arranged in the adjustment pipe 6, and the adjustment mechanism can slide into the valve body seat 1. The adjustment mechanism is used to adjust the flow rate of the water mist sprayed by the nozzle 4. A plurality of cleaning needles 7 are provided, and the plurality of cleaning needles 7 are slidably arranged in the adjustment mechanism. The cleaning needles 7 correspond to the spray openings 5, and the cleaning needles 7 can slide into the spray openings 5. During normal use, the adjustment mechanism is controlled by the control sleeve 10, thereby controlling the flow rate of the gas and liquid entering the valve body seat 1, and further controlling the spraying speed of the spray openings 5. When cleaning is required, the plurality of cleaning needles 7 can specifically clean the spray openings 5 without affecting the spraying.
[0023] As Figures 1 to 3 shown, a mixing chamber 8, a fixed shaft 9, and a control sleeve 10 are arranged on the valve body seat 1. The mixing chamber 8 is arranged in the center of the valve body seat 1. The gas inlet 2, the liquid inlet 3, and the spray openings 5 are all communicated with the mixing chamber 8. The fixed shaft 9 is fixedly connected to the valve body seat 1. The fixed shaft 9 passes through the adjustment pipe 6 and the mixing chamber 8. The fixed shaft 9 is detachably connected to the nozzle 4. The control sleeve 10 is sleeved on the fixed shaft 9, and the control sleeve 10 is rotatably connected to the fixed shaft 9. A threaded section is arranged on the control sleeve 10, and the threaded section on the control sleeve 10 is threadedly connected to the adjustment mechanism. The gas and liquid are mixed and impacted in the mixing chamber 8, and after forming water mist, they are discharged at the spray openings 5. The gas inlet 2 is connected to an external air pump, and the liquid inlet 3 is connected to an external water pump. The fixed shaft 9 passes through the control sleeve 10, and the fixed shaft 9 is used to guide and position the control sleeve 10 and fix the nozzle 4.
[0024] As Figures 2 to 3As shown in the figure, an adjustment cavity 11, a blockage clearing cavity 12 and a partition plate 13 are provided on the adjustment pipe 6. The adjustment cavity 11 is arranged on one side of the adjustment pipe 6 close to the mixing cavity 8, and the adjustment cavity 11 is communicated with the mixing cavity 8. The threaded section on the adjustment sleeve 10 is arranged in the adjustment cavity 11. The blockage clearing cavity 12 is arranged on one side of the adjustment pipe 6 far from the mixing cavity 8. The partition plate 13 is arranged between the adjustment cavity 11 and the blockage clearing cavity 12. A plurality of blockage clearing needles 7 penetrate and are slidably connected with the partition plate 13, and the adjustment sleeve 10 penetrates and is rotatably connected with the partition plate 13. The adjustment cavity 11 and the blockage clearing cavity 12 are separated by the partition plate 13. The blocking slider 14 is in close fit with the adjustment cavity 11, so that the liquid in the mixing cavity 8 will not enter the adjustment cavity 11.
[0025] As Figures 2 to 5 shown in the figure, the adjustment mechanism includes a blocking slider 14 and a runner 15. The blocking slider 14 is slidably arranged in the adjustment cavity 11 and the mixing cavity 8. The blocking slider 14 is sleeved on the fixed shaft 9 and the adjustment sleeve 10. One end of the blocking slider 14 close to the blockage clearing cavity 12 is threadedly connected with the threaded section on the adjustment sleeve 10. The runner 15 is fixedly connected to the adjustment sleeve 10. The runner 15 is arranged at one end of the adjustment pipe 6 far from the mixing cavity 8. When the blocking slider 14 slides into the mixing cavity 8 and the blocking slider 14 contacts the two inclined pipe orifices 20, the flow rates of the gas and the liquid can be adjusted. The rotation of the runner 15 can drive the adjustment sleeve 10 to rotate on the fixed shaft 9. At the same time, the threaded section on the adjustment sleeve 10 rotates to push the blocking slider 14 to slide in the adjustment cavity 11. When one end of the blocking slider 14 close to the mixing cavity 8 gradually intersects with the inclined pipe orifice 20, the flow rates of the gas and the liquid can be controlled simultaneously. At the same time, since a plurality of blockage clearing needles 7 are slidably connected with the blocking slider 14, the liquid in the mixing cavity 8 will not enter the compression cavity 17.
[0026] As Figures 3 to 6As shown in the figure, the clogging removal mechanism includes a clogging removal hole 16 and a compression chamber 17. There are multiple clogging removal holes 16, which are opened on the plugging slider 14. A clogging removal needle 7 is slidably connected in each clogging removal hole 16. The compression chamber 17 is opened on the plugging slider 14. A spring is arranged in the compression chamber 17. The spring is arranged between the clogging removal needle 7 and the compression chamber 17. The spring pushes the clogging removal needle 7 in the plugging slider 14 in a direction away from the mixing chamber 8. One end of the clogging removal needle 7 located in the clogging removal chamber 12 is provided with a pushing plate 18. Multiple strip grooves 19 are opened on the clogging removal chamber 12. The pushing plate 18 penetrates through the strip grooves 19. When the pushing plate 18 is pushed in the direction of the mixing groove, the pushing plate 18 slides in the strip grooves 19, and the clogging removal needle 7 slides in the plugging slider 14 towards the nozzle 5. The clogging removal needle 7 compresses the spring. The clogging removal needle 7 extends into the nozzle 5. One end of the clogging removal needle 7 close to the nozzle 5 is provided with multiple teeth. When the nozzle 5 is blocked, no matter which position the plugging slider 14 slides to, the pushing plate 18 can be slid in the strip grooves 19, so that the clogging removal needle 7 compresses the spring. The multi-toothed end of the clogging removal needle 7 moves towards the nozzle 5 in the mixing chamber 8 until it extends into the nozzle 5, breaking and extruding the blocked impurities, which can realize targeted clogging removal of the nozzle 5. At the same time, since multiple clogging removal needles 7 can be used separately, when some clogging removal needles 7 are used, the gas and liquid in the mixing chamber 8 will be ejected through the unblocked nozzles 5, which does not affect the water mist spraying during clogging removal. At the same time, the water pressure and air pressure can also make the impurities be quickly discharged.
[0027] As Figures 3 to 4 shown in the figure, it further includes a flow guiding mechanism. There are two flow guiding mechanisms, which are respectively arranged in the gas inlet 2 and the liquid inlet 3. The flow guiding mechanism is used to make the gas and liquid impact and mix in the mixing chamber 8. The flow guiding mechanism includes an inclined pipe orifice 20 and an arc-shaped groove 21. The inclined pipe orifice 20 is arranged at the connection between the gas inlet 2 or the liquid inlet 3 and the mixing chamber 8. The arc-shaped groove 21 is opened on the valve body seat 1. The arc-shaped groove 21 is arranged at a relative position inside the mixing chamber 8 opposite to the inclined pipe orifice 20. The inclined pipe orifices 20 in the two flow guiding mechanisms face two opposite directions. Through the inclined pipe orifice 20, the gas and liquid both enter the mixing chamber 8 at a certain angle. The gas or liquid rushing out of the inclined pipe orifice 20 will impact on the arc-shaped groove 21. Since the arc-shaped groove 21 is parallel to the gas inlet 2 and the liquid inlet 3, the gas and liquid will rotate after being fixed and surrounded in the mixing chamber 8. While rotating, the gas and liquid impact each other, making them mix into water mist and be ejected at the nozzle 5 under the impact of pressure, avoiding the gas and liquid being ejected separately at the nozzles 5 on both sides without sufficient impact and mixing.
[0028] In some examples, the gas pipeline and the liquid pipeline are respectively communicated with the gas inlet 2 and the liquid inlet 3. The gas and the liquid impact and mix into water mist in the mixing chamber 8. The position of the blocking slider 14 is adjusted by rotating the runner 15, and accordingly, the speeds of the gas and the liquid entering the mixing chamber 8 are adjusted. The multiple nozzles 5 can be respectively cleaned by sliding the clogging clearing needle 7, and the blocked impurities are ejected through the nozzles 5.
[0029] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
