Description
Technical Field
[0001] This invention relates to the field of nozzle technology, specifically to an adjustable backwashing spray mechanism for dust suppression in mining. Background Technology
[0002] Coal mines generate a large amount of dust during construction, which is typically suppressed by spraying water to purify the airflow, improve the working environment, prevent dust hazards, and protect workers' health. However, the water used for dust suppression in coal mines contains impurities. To prevent the atomizing nozzles from clogging after prolonged use, filters are installed in the spray system to remove these impurities. These filters also require cleaning to ensure stable and long-term operation. Existing spray systems typically use backwashing to clean the filters, where water flows in the opposite direction to remove impurities from the filter media and restore its filtration capacity. This is very convenient and saves considerable manpower. However, existing mine spray systems have some shortcomings: the atomizing nozzles are generally fixed in their working positions, making it difficult to easily adjust their spray range. Sometimes it's necessary to raise the installation height to increase the spray range and better capture dust, while other times it's necessary to lower the installation height to reduce the spray range for precise spraying, saving water and avoiding waste. Summary of the Invention
[0003] The purpose of this invention is to provide an adjustable spray mechanism for backwashing in mining dust suppression, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] An adjustable spray mechanism for backwashing in mining dust suppression includes: a water delivery pipe, on which a loading water pipe is fixedly installed;
[0006] Atomizing nozzle, wherein the atomizing nozzle is sealed to the water supply pipe;
[0007] A nozzle support assembly is used to support the atomizing nozzle and to install the atomizing nozzle on the water supply pipe.
[0008] An interlocking assembly is installed on the atomizing nozzle to lock the position of the atomizing nozzle and also to lock the nozzle support assembly, ensuring its secure installation.
[0009] A spray range adjustment component is also installed on the atomizing nozzle, which cooperates with the nozzle support component to adjust the spray range of the atomizing nozzle.
[0010] Preferably, a connecting pipe is fixedly provided on the atomizing nozzle, and a fitting cavity is provided on the water supply pipe;
[0011] The connecting pipe is inserted into the fitting cavity of the pipe to achieve a sealed connection between the atomizing nozzle and the water supply pipe.
[0012] Preferably, the nozzle support assembly includes: a load-bearing support ring, wherein when the atomizing nozzle is installed on the load-bearing water pipe, the load-bearing support ring is sleeved on the load-bearing water pipe;
[0013] The movable strip is installed, which cooperates with the load distribution water pipe to install the load distribution support ring on the load distribution water pipe.
[0014] Preferably, the load-bearing support ring is symmetrically fixed with an extended protrusion plate, and an installation movable strip is installed on the extended protrusion plate.
[0015] Preferably, the atomizing nozzle cooperates with the extended protrusion plate, and the extended protrusion plate supports the atomizing nozzle.
[0016] Preferably, the interlocking assembly includes: a movable frame plate, which is mounted on the atomizing nozzle;
[0017] A threaded carrier is installed on a movable frame plate, which cooperates with the atomizing nozzle to lock the movable frame plate.
[0018] Preferably, the movable frame plate cooperates with the mounting movable strip to lock the atomizing nozzle and the mounting movable strip at the same time.
[0019] Preferably, the spray range adjustment assembly includes: two drive support plates, which are symmetrically installed on the atomizing nozzle;
[0020] A conical adjusting sleeve, which is fitted onto the atomizing nozzle;
[0021] The locking plates are two in number and are symmetrically installed on the conical adjusting sleeve.
[0022] Preferably, the drive support plate is movably connected to the conical adjusting sleeve, which drives the conical adjusting sleeve to move up and down relative to the atomizing nozzle.
[0023] Preferably, when the conical adjusting sleeve moves upward relative to the atomizing nozzle, it increases the spray range of the atomizing nozzle; when the conical adjusting sleeve moves downward relative to the atomizing nozzle, it decreases the spray range of the atomizing nozzle.
[0024] Preferably, the mating sealing plate is movably connected to the atomizing nozzle, and the tapered adjusting sleeve moves up and down relative to the atomizing nozzle, causing the mating sealing plate to move as well.
[0025] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a reasonable structural design and strong functionality, and has the following advantages:
[0026] 1. Install the atomizing nozzle on the load-bearing support ring, and then install the atomizing nozzle on the water delivery pipe through the load-bearing support ring. In actual operation, the installation height of the atomizing nozzle can be increased to increase its spray range, or the installation height of the atomizing nozzle can be decreased to reduce its spray range, so as to meet different working needs. The operation is simple, convenient and quick.
[0027] 2. When it is necessary to expand the spray range of the atomizing nozzle, pull the movable frame to unlock the atomizing nozzle, then push the atomizing nozzle upwards to move it upwards. This will increase the installation height of the atomizing nozzle. Simultaneously, as the atomizing nozzle moves upwards, the conical adjusting sleeve will also move upwards relative to the atomizing nozzle, thus increasing the spray range. When it is necessary to reduce the spray range of the atomizing nozzle, similarly, pull the movable frame to unlock the atomizing nozzle, then pull the atomizing nozzle downwards to move it downwards. This will reduce the installation height of the atomizing nozzle, and as the atomizing nozzle moves downwards, the conical adjusting sleeve will move downwards relative to the atomizing nozzle, thus reducing the spray range. This allows for quick adjustment.
[0028] 3. In addition, when the atomizing nozzle is not in operation, the sealing plate is closed, which can seal the lower port of the conical adjusting sleeve. This effectively prevents coal mine dust from entering the conical adjusting sleeve and provides good protection for the atomizing nozzle, preventing it from being blocked by external dust and impurities. When the atomizing nozzle is in operation, as the conical adjusting sleeve moves upward, it can drive the sealing plate to move in the opposite direction, so that the lower port of the conical adjusting sleeve is in the open state, ensuring smooth atomization spraying.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] This invention provides a technical solution:
[0042] like Figure 1As shown, a backwashing adjustable spray mechanism for dust suppression in mining includes: a water delivery pipe 2, an atomizing nozzle 1, a nozzle support assembly, an interlocking assembly, and a spray range adjustment assembly. A loading water pipe 21 is welded and fixed to the water delivery pipe 2. The atomizing nozzle 1 is sealed to the loading water pipe 21. The nozzle support assembly supports the atomizing nozzle 1 and mounts it onto the loading water pipe 21. The interlocking assembly is mounted on the atomizing nozzle 1 to lock its position and also locks the nozzle support assembly, ensuring its secure installation. The spray range adjustment assembly is also mounted on the atomizing nozzle 1 and works in conjunction with the nozzle support assembly to adjust the spray range of the atomizing nozzle 1.
[0043] like Figure 6 As shown, a connecting pipe 11 is welded and fixed to the atomizing nozzle 1. A symmetrically integrally formed outer support plate 12 is provided on the connecting pipe 11 near the atomizing nozzle 1. An installation support strip 13 is integrally formed on the outer support plate 12. An installation support insertion hole 14 is symmetrically opened on the installation support strip 13. A plug-in connecting plate 15 is welded and fixed to the upper end of the installation support strip 13. A load-bearing top block 16 is integrally formed on the upper end of the plug-in connecting plate 15. A matching channel 17 is opened on the load-bearing top block 16. A frame-shaped plate frame 18 is welded and fixed to the load-bearing top block 16. An inner support protrusion plate 19 is integrally formed on the inner side of the frame-shaped plate frame 18. A moving channel 191 is opened on the inner support protrusion plate 19. An expansion groove 192 is also opened on the inner support protrusion plate 19. The expansion groove 192 communicates with the moving channel 191.
[0044] like Figure 1 and Figure 2 As shown, the water distribution pipe 21 has a fitting cavity 22, and the upper end of the water distribution pipe 21 is symmetrically and integrally formed with a bearing installation block 23, and the bearing installation block 23 has a locking cavity 24.
[0045] The connecting pipe 11 is inserted into the fitting cavity 22 to achieve a sealed connection between the atomizing nozzle 1 and the water supply pipe 21.
[0046] like Figure 1 and Figure 7 As shown, the nozzle support assembly includes a load-bearing support ring 3 and a mounting movable strip 4. When the atomizing nozzle 1 is installed on the load-bearing water pipe 21, the load-bearing support ring 3 is sleeved on the load-bearing water pipe 21, and the inner wall of the load-bearing support ring 3 is smooth and burr-free, and the inner wall of the load-bearing support ring 3 is in contact with the outer end face of the load-bearing water pipe 21.
[0047] The mounting strip 4 is used in conjunction with the water distribution pipe 21 to install the water distribution support ring 3 on the water distribution pipe 21. The upper end of the mounting strip 4 is integrally formed with a locking pin 41. When the locking pin 41 fixes the water distribution support ring 3 on the water distribution pipe 21, it is inserted into the locking cavity 24.
[0048] Symmetrically welded to the load-balanced support ring 3 are extended protruding plates 31, on which mounting movable strips 4 are installed. A connecting channel 32 is also provided on the extended protruding plate 31. Furthermore, a load-balanced upright plate 33 is integrally formed at the end of the extended protruding plate 31 away from the load-balanced support ring 3. The load-balanced upright plate 33 has a movable through hole 34 and a limiting loading groove 35, with the limiting loading groove 35 located above the movable through hole 34. A lower connecting bearing plate 36 is integrally formed at the lower end of the extended protruding plate 31, and a slanted panel frame 37 is integrally formed on the lower connecting bearing plate 36. The surface of the slanted panel frame 37 is smooth and burr-free. The movable mounting strip 4 has an anti-slip insertion hole 42, and a limiting carrier plate 43 is integrally formed on the movable mounting strip 4. The limiting carrier plate 43 is inserted into the limiting carrier groove 35 and contacts the inner wall of the limiting carrier groove 35. A movable bearing rod 44 is also welded and fixed on the movable mounting strip 4. The movable bearing rod 44 is inserted into the movable through hole 34, and a first connecting spring 45 is sleeved on the movable bearing rod 44. The two ends of the first connecting spring 45 are respectively welded to the movable mounting strip 4 and the mounting plate 33. In addition, an insertion through groove 46 is also provided on the lower side of the movable mounting strip 4. The inner wall of the insertion through groove 46 is smooth and burr-free.
[0049] like Figure 5 As shown, the atomizing nozzle 1 is engaged with the extended protrusion plate 31, which supports the atomizing nozzle 1. The connecting plate 15 is inserted into the connecting channel 32, and the loading top block 16 is located on the upper side of the extended protrusion plate 31.
[0050] like Figure 8 and Figure 9 As shown, the interlocking assembly includes: a movable frame plate 5 and a threaded support column 52. The movable frame plate 5 is mounted on the atomizing nozzle 1. The movable frame plate 5 has a threaded through hole 51, and a support plate 54 is symmetrically welded and fixed on the movable frame plate 5. A locking plug plate 55 is integrally formed on the support plate 54. When the atomizing nozzle 1 is not moving upward, the locking plug plate 55 is inserted into the plug slot 46. A matching support rod 56 is also welded and fixed on the support plate 54. The matching support rod 56 is inserted into the matching channel 17, and a matching end plate 57 is welded and fixed to the end of the matching support rod 56 away from the support plate 54. In addition, a second connecting spring 58 is sleeved on the matching support rod 56. The two ends of the second connecting spring 58 are respectively welded to the matching end plate 57 and the load-bearing top block 16.
[0051] The threaded support post 52 is installed on the movable frame plate 5, and it cooperates with the atomizing nozzle 1 to lock the movable frame plate 5. The threaded support post 52 is threaded into the threaded through hole 51, and the upper end of the threaded support post 52 is integrally formed with a positioning block 53. When the positioning block 53 locks the movable frame plate 5, it is inserted into the expansion groove 192 and contacts the inner wall of the expansion groove 192.
[0052] The movable frame 5 cooperates with the mounting movable strip 4 to lock the atomizing nozzle 1 and the mounting movable strip 4 at the same time. That is, at this time, the locking plug plate 55 on the bearing plate 54 is inserted into the anti-movement plug hole 42.
[0053] like Figure 3 , Figure 4 , Figure 8 and Figure 10 As shown, the spray range adjustment assembly includes: a drive support plate 6, a conical adjustment sleeve 7, and a mating sealing plate 8. There are two drive support plates 6, which are symmetrically installed on the atomizing nozzle 1. The conical adjustment sleeve 7 is sleeved on the atomizing nozzle 1. There are two mating sealing plates 8, which are symmetrically installed on the conical adjustment sleeve 7, and the mating sealing plate 8 is located on the lower side of the conical adjustment sleeve 7.
[0054] The drive support plate 6 is movably connected to the conical adjusting sleeve 7, causing the conical adjusting sleeve 7 to move up and down relative to the atomizing nozzle 1. A mating wheel 61 is installed on the drive support plate 6, and the mating wheel 61 contacts the inclined panel frame 37. A mounting support rod 62 is symmetrically welded and fixed on the drive support plate 6. The mounting support rod 62 is inserted into the mounting support insertion hole 14. A connecting load block 63 is also symmetrically integrally formed on the drive support plate 6. A first adjusting connecting rod 64 is hinged on the connecting load block 63. The upper end of the first adjusting connecting rod 64 is hinged to the conical adjusting sleeve 7. An adjusting bearing plate 71 is symmetrically welded and fixed on the conical adjusting sleeve 7. A connecting top plate 72 is integrally formed on the upper end of the adjusting bearing plate 71. The two ends of the connecting top plate 72 are respectively hinged to the first adjusting connecting rod 64. In addition, a bearing mating rod 73 is also symmetrically welded and fixed on the conical adjusting sleeve 7.
[0055] When the conical adjusting sleeve 7 moves upward relative to the atomizing nozzle 1, it increases the spray range of the atomizing nozzle 1; when the conical adjusting sleeve 7 moves downward relative to the atomizing nozzle 1, it decreases the spray range of the atomizing nozzle 1.
[0056] The sealing plate 8 is movably connected to the atomizing nozzle 1. When the conical adjusting sleeve 7 moves up and down relative to the atomizing nozzle 1, it drives the sealing plate 8 to move. The sealing plate 8 is integrally formed with a connecting support strip 81. The connecting support strip 81 has a movable mating hole 82. A bearing mating rod 73 is inserted into the movable mating hole 82. The upper end of the connecting support strip 81 is hinged to a second adjusting rod 83. The upper end of the second adjusting rod 83 is hinged to the protruding support plate 12.
[0057] During the installation of the atomizing nozzle 1, push the two mounting strips 4 in opposite directions, then insert the connecting pipe 11 into the fitting cavity 22, aligning the locking pins 41 on the mounting strips 4 with the locking cavity 24. Release the mounting strips 4 one by one until the locking pins 41 are inserted into the locking cavity 24, thus completing the installation of the atomizing nozzle 1. At this point, the atomizing nozzle 1 is at its lowest installation position, which is the non-working state, and the sealing plate 8 is in the closed state. When using the atomizing nozzle 1, rotate the threaded support post 52 to disengage the positioning block 53 from the expansion slot 192, thereby unlocking the movable frame 5. Pull the movable frame 5 to move it, thus... When the locking plug plate 55 retracts from the plug slot 46, the atomizing nozzle 1 is unlocked. Then, the atomizing nozzle 1 can be moved upwards. When the locking plug plate 55 reaches the lowest anti-shifting plug hole 42, the atomizing nozzle 1 is in its lowest working position. As the atomizing nozzle 1 moves upwards, the inclined plate bracket 37 pushes the drive support plate 6 towards the connecting pipe 11. This causes the conical adjusting sleeve 7 to move upwards relative to the atomizing nozzle 1 under the action of the first adjusting rod 64. Simultaneously, as the conical adjusting sleeve 7 moves upwards, the second adjusting rod 83 causes the two mating sealing plates 8 to move in opposite directions, so that the lower end of the conical adjusting sleeve 7 is in the... When the nozzle is in the open state, adjusting the spray range of the atomizing nozzle 1 only requires adjusting it within the range of the anti-shifting socket 42. Specifically, when the atomizing nozzle 1 moves upward, its spray height increases, and the conical adjusting sleeve 7 moves upward relative to the atomizing nozzle 1. This reduces the distance between the nozzle opening of the atomizing nozzle 1 and the lower end of the conical adjusting sleeve 7, thereby increasing the spray range. Conversely, when the atomizing nozzle 1 moves downward, its spray height decreases, and the conical adjusting sleeve 7 moves downward under its own gravity, increasing the distance between the lower end of the conical adjusting sleeve 7 and the nozzle opening of the atomizing nozzle 1. This reduces the spray range within the constraint of the conical adjusting sleeve 7, achieving precise spraying and avoiding water waste. The atomizing nozzle 1 is not wasteful. After the position is adjusted, the movable frame 5 can be reset under the action of the second connecting spring 58, so that the locking plug plate 55 can be inserted into the anti-slip plug hole 42. This fixes the atomizing nozzle 1 and the movable strip 4, ensuring the firmness of the atomizing nozzle 1 installation. Then, the threaded column 52 is rotated so that the positioning plug 53 is inserted into the expansion slot 192 to fix the movable frame 5. When the atomizing nozzle 1 is not working, the lower port of the conical adjusting sleeve 7 is sealed with the sealing plate 8 to prevent dust and impurities in the coal mine from clogging the atomizing nozzle 1. The installation and removal of the atomizing nozzle 1 is also very convenient.
