Description

Technical Field

[0001] This utility model relates to the field of atomizing nozzle technology, and in particular to a high-efficiency atomizing nozzle for a dust suppression vehicle. Background Technology

[0002] With rapid urbanization and increasingly frequent industrial activities, dust pollution has become a significant source of air pollution, seriously impacting the ecological environment and residents' health. As an effective dust control device, the performance of the atomizing nozzle, a core component of dust suppression vehicles, directly determines their dust suppression effectiveness.

[0003] The existing atomizing nozzles of dust suppression vehicles have some shortcomings. On the one hand, the nozzle installation structure is mostly fixed, making it difficult to flexibly adjust the spray angle according to the actual working conditions, which limits the dust suppression range and cannot meet the dust suppression needs in complex scenarios. On the other hand, the water flow channel design of traditional nozzles is relatively simple. After the water flows through the spray ring pipe and nozzle, it directly enters the nozzle. The flow state is relatively simple, which limits the atomization effect of the nozzle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-efficiency atomizing nozzle for dust suppression vehicles, which has the advantages of flexible adjustment of the spray angle, stable fixation, and high-efficiency atomization performance, thus solving some of the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a high-efficiency atomizing nozzle for a dust suppression vehicle, comprising a ball sleeve and a spray ring tube. A rotating ball is rotatably installed inside the ball sleeve. An external threaded tube is fixedly connected to the middle of the right end of the rotating ball. A mist cannon nozzle is threadedly sleeved at the right end of the external threaded tube. An adjustment groove is provided at the middle of the upper and lower sides of the right end of the ball sleeve. The external threaded tube is adapted to the adjustment groove. A rotating rod is fixedly connected to the center of both the front and rear ends of the rotating ball. An internal threaded cylinder is fixedly installed at the corresponding rotating rod at both the front and rear ends of the ball sleeve. The rotating rod extends through the internal threaded cylinder to the outside. A limit block is symmetrically provided on the rotating rod at the end away from the rotating ball. A rod sleeve is fitted on the outside of the rotating rod. The rod sleeve is provided with an external thread. The rod sleeve is threadedly connected to the internal threaded cylinder through the external thread.

[0006] Furthermore, the left end of the ball sleeve is fixedly connected to an internally threaded tube, and the spray ring tube is provided with evenly distributed threaded nozzles. The internally threaded tube is threaded onto the threaded nozzles. In order to better illustrate the design scheme, only a part of the spray ring tube is shown in this figure. Please refer to the actual spray ring tube for details.

[0007] Furthermore, a tapered oblique section is provided at the middle of the left end of the ball sleeve, and a flared section is provided at the middle of the left end of the rotating ball. The maximum diameter of the flared section is greater than the maximum diameter of the tapered oblique section. The design of the flared section allows the high-pressure water flow to enter the water channel better, avoiding unnecessary obstruction and accelerating structural wear.

[0008] Furthermore, a water channel is provided in the middle of the interior of the rotating ball, and the right end of the water channel is connected to the external threaded pipe. The external threaded pipe is connected to the mist cannon nozzle. Compared with the traditional structural design, the external threaded pipe design in this solution is similar to the traditional nozzle function.

[0009] Furthermore, each of the rod sleeves is symmetrically provided with a sliding groove at one of its far ends. The limiting block passes through and is slidably connected inside the sliding groove. The length of the sliding groove is greater than the thickness of the limiting block. The sliding groove and the limiting block are matched to prevent the rotating rod from shaking.

[0010] Furthermore, a fastening nut is threadedly connected to the outer side of the sleeve via an external thread. A washer is movably fitted between the fastening nut and the internal threaded cylinder on the outer side of the sleeve. The fastening nut is pressed against the internal threaded cylinder by the washer. It is worth noting that the sleeve needs to be held and fixed during the adjustment of the spray angle of the fog cannon nozzle to prevent the sleeve from rotating when the fastening nut is tightened, which would cause the adjustment to fail.

[0011] The advantages of this utility model are as follows:

[0012] 1. Through the coordinated design of structures such as fastening nuts, internal threaded cylinders, rod sleeves, and limiting blocks, the angle of the fog cannon nozzle can be flexibly adjusted and fixed. Tightening the fastening nut can release or lock the nozzle, making operation convenient. The threaded connection of the limiting block and the gasket allows the nozzle to maintain a fixed angle when subjected to external forces such as vibration and impact.

[0013] 2. By utilizing the tapered oblique surface, the flared surface, and the diameter variation of the water passage, the water flow forms a complex turbulent and vortex state inside the nozzle, changing the water pressure and velocity, and impacting the nozzle in a more complex and varied way, causing the water to be fully broken into smaller and more uniform water droplets, thereby improving the atomization effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 A high-efficiency atomizing nozzle for a dust suppression vehicle includes a ball sleeve 1 and a spray ring pipe 6. A rotating ball 2 is rotatably mounted inside the ball sleeve 1. An externally threaded pipe 3 is fixedly connected to the middle of the right end of the rotating ball 2. A mist cannon nozzle 4 is threadedly fitted onto the right end of the externally threaded pipe 3. Adjustment grooves 11 are provided at the middle of the upper and lower sides of the right end of the ball sleeve 1. The externally threaded pipe 3 is adapted to the adjustment grooves 11. Rotating rods 12 are fixedly connected to the center of both the front and rear ends of the rotating ball 2. Internally threaded cylinders 15 are fixedly installed at the corresponding rotating rods 12 at both the front and rear ends of the ball sleeve 1. The rotating rods 12 extend outwards through the internally threaded cylinders 15. Limiting blocks 13 are symmetrically arranged on the rotating rods 12 at the end furthest from the rotating ball 2. A rod sleeve 14 is fitted onto the outer side of the rotating rod 12. An externally threaded nozzle is provided on the rod sleeve 14. The rod sleeve 14 is threadedly connected to the internally threaded cylinder 15 via external threads. After adjusting the angle of the mist cannon nozzle 4, it needs to be fixed. By rotating the fastening nut 16, the washer 17 is brought into contact with the internally threaded cylinder 15. The washer 17 generates a reverse elastic force, which helps to maintain the tightness of the fastening nut 16 and reduces the possibility of the nut loosening due to vibration, impact, or other water flow effects. At the same time, the rod sleeve 14 is also connected to the internal threads of the internally threaded cylinder 15. Under the limiting action of the limiting block 13, the limiting and fixing operation of the rotating rod 12 is realized, thus completing the fixing of the current angle of the mist cannon nozzle 4. Compared with the traditional fixed installation structure, this mist cannon nozzle 4 is more flexible in use and has a wider range of applications.

[0021] Please see Figure 1The left end of the ball sleeve 1 is fixedly connected to an internal threaded tube 5. The spray ring tube 6 is provided with evenly distributed threaded nozzles 7. The internal threaded tube 5 is threaded onto the threaded nozzles 7. Through the threaded connection between the internal threaded tube 5 and the threaded nozzles 7, the structure such as the fog cannon nozzle 4 is installed on the fog cannon machine of the dust suppression vehicle.

[0022] Please see Figure 3 The ball sleeve 1 has a tapered oblique surface 8 at the middle of its left end, and the rotating ball 2 has a flared surface 9 at the middle of its left end. The maximum diameter of the flared surface 9 is greater than the maximum diameter of the tapered oblique surface 8. A water channel 10 is provided in the middle of the interior of the rotating ball 2. The right end of the water channel 10 is connected to the external threaded pipe 3, and the external threaded pipe 3 is connected to the mist cannon nozzle 4. The design of the flared surface 9 ensures that the water flow can normally enter the interior of the water channel 10 through the flared surface 9 after the angle of the mist cannon nozzle 4 is adjusted, thus ensuring the integrity and rationality of this technical solution. At the same time, the tapered oblique surface 8, the flared surface 9, and the variable diameter treatment of the water channel 10 can improve the more complex flow state when the water flows through, thereby impacting the mist cannon nozzle 4 in a more complex and diverse way, making the water easier to break into smaller water droplets, and thus improving the atomization effect.

[0023] Please see Figure 4 Each sleeve 14 has a symmetrically arranged groove 18 at its far ends. A limiting block 13 passes through and is slidably connected inside the groove 18. The length of the groove 18 is greater than the thickness of the limiting block 13. A fastening nut 16 is threadedly connected to the outside of the sleeve 14 via an external thread. A washer 17 is movably fitted between the fastening nut 16 and the internal threaded cylinder 15 on the outside of the sleeve 14. The fastening nut 16 is pressed against the internal threaded cylinder 15 by the washer 17. The fastening nut 16 is tightened by screwing on the fastening nut 16 to make it fit against the internal thread. Separate the cylinders 15 to release the tightening of the sleeve 14, and then directly rotate the mist cannon nozzle 4 inside the adjusting groove 11 to the required expansion angle. During this process, the rotating ball 2 will be driven to rotate synchronously. The rotation of the rotating ball 2 will drive the rotating rod 12 to rotate, and the rotation of the rotating rod 12 will drive the sleeve 14 to rotate. The sleeve 14 is threadedly connected to the internal threaded cylinder 15. When the sleeve 14 rotates, it will shift relative to the internal threaded cylinder 15. The displacement compensation is achieved by the sliding groove 18 to ensure the rationality of the structure.

[0024] Working principle: By tightening the fastening nut 16 to separate it from the internal threaded cylinder 15, the tightness of the sleeve 14 is released. Then, the mist cannon nozzle 4 is directly rotated inside the adjusting groove 11 to the required expansion angle. During this process, the rotating ball 2 is synchronously driven to rotate, which in turn drives the rotating rod 12 to rotate, which in turn drives the sleeve 14 to rotate. The sleeve 14 is threadedly connected to the internal threaded cylinder 15. When the sleeve 14 rotates, it will shift relative to the internal threaded cylinder 15. The sliding groove 18 provides displacement compensation. Furthermore, after adjusting the angle of the mist cannon nozzle 4, it needs to be fixed. This is done by rotating the fastening nut 16 to move the washer 17 and the internal threaded cylinder 15 together. The pressure is applied by the gasket 17, which generates a reverse elastic force, thus helping to maintain the tightened state of the fastening nut 16. At the same time, the sleeve 14 is connected to the internal thread of the internal threaded cylinder 15. Under the limiting action of the limiting block 13, the limiting and fixing operation of the rotating rod 12 is realized, that is, the current angle of the mist cannon nozzle 4 is fixed. In addition, the design of the flared section 9 ensures that the water flow can normally enter the interior of the water passage 10 through the flared section 9 after the angle of the mist cannon nozzle 4 is adjusted. At the same time, the tapered oblique section 8, the flared section 9 and the diameter change treatment of the water passage 10 can improve the more complex flow state when the water flows through, thus impacting the mist cannon nozzle 4 in a more complex and diverse way.
