Description

Technical Field

[0001] The invention relates to the technical field of atomization dust reduction in construction engineering, and more specifically, to an atomization dust reduction device for construction engineering. Background Art

[0002] In the current field of construction engineering, existing atomization dust reduction devices have limitations. The most prominent problem is the limitation of their spray range. The current atomization device design mainly focuses on spraying inside the spray tube. This single spray method limits the coverage area of ​​dust reduction. Since construction sites are usually large in area, when dust is widely distributed, relying on internal spraying will reduce the dust problem in the construction area. This design defect leads to a significant reduction in the dust reduction effect and cannot meet the comprehensive dust reduction needs of large construction sites, which may affect the air quality of the construction environment and the health and safety of workers.

[0003] Another significant problem is the lubrication of the spiral blades in the existing atomizing dust suppression device. Under long-term continuous operation, the spiral blades lack an effective lubrication mechanism, which directly affects the operating efficiency and service life of the entire device. Without proper lubrication, the spiral blades are prone to excessive friction and wear, which not only increases energy consumption, but may also cause premature damage to the equipment.

[0037] Working principle: when it is necessary to atomize and reduce dust on the construction site, since the base 1 is installed on an external mobile device, the spray tube 2 can be driven to move to the corresponding position through the mobile device, and then the motor 31 is started. The spiral blade 29 is driven to rotate under the action of the motor 31, so that a large wind force can be generated. At the same time, water is supplied to the water inlet pipe 4 through external equipment, and then enters the water spray sleeve 3. Then the water spray sleeve 3 will press water into multiple nozzles 5 through the water inlet groove 11, and then the nozzle 5 will spray the water. When the water passes through the nozzle 5, there will be a certain amount of atomization, and then it will be effectively atomized by a large wind force. Then a part of the water mist is directly sprayed to the area pointed by the spray tube 2 through the wind force. The water mist and dust combine and then play a role in dust reduction. At this time, the water mist sprayed on the side wall of the water spray sleeve 3 will rotate around with the wind force, but the kinetic energy of the water mist on the side wall is less than that of the water mist in the axial direction, so it will also have a certain dust reduction effect on the surrounding positions, thereby improving the overall dust reduction effect, and then improving the purification effect on the construction area.

[0038] When it is necessary to open the nozzle 5 on the inner wall of the water spray sleeve 3, first, by pulling the transverse sleeve 18, multiple limit rings 19 will move it forward, so that the transverse groove 20 is slidably connected in the hexagonal rod 9, the groove 21 will abut on the follower ball 10, and then drive the hexagonal rod 9 to pull upward, at this time, the spring 17 will continue to be compressed, and then the conical sleeve 15 will be pulled upward to release the seal between the fitting sleeve 14. Since the water from the water inlet groove 11 flows into the nozzle 5, the water has a greater pressure. Finally, there will be greater kinetic energy between the conical sleeve 15 and the fitting sleeve 14 to generate water mist, thereby ensuring that the nozzle 5 on the water spray sleeve 3 starts to spray.

[0039] When it is necessary to open the nozzle 5 on the outer wall of the water spray sleeve 3, since the coaxial sleeve 23 is slidably connected to multiple annular blocks 24, the opening and stopping of each nozzle 5 can be controlled individually. First, under the action of the lever 28, the annular block 24 can slide along the coaxial center, at this time, the unlocking groove 26 on the unlocking block 25 will abut against the follow-up ball 10, and then the hexagonal rod 9 will be pulled upward, and then the nozzle 5 can be opened to form water mist, thereby ensuring that the nozzle 5 on the outer wall can perform the process of spraying and dust reduction.

[0040] When each nozzle 5 needs to be adjusted, first, inserting a wrench into the top groove 13 can drive the rotation of the follower ball 10. At this time, the adjusting tube 6 is fixed by the wrench. Since the hexagonal rod 9 is slidably connected in the hexagonal groove 12, it will drive the intermediate sleeve 8 and the adjusting tube 6 to rotate relative to each other, and the intermediate sleeve 8 is threadedly connected in the adjusting tube 6, so the relative position of the intermediate sleeve 8 and the adjusting tube 6 can be changed, and then the compression amount of the spring 17 can be changed to change the strength of the seal, thereby ensuring the normal sealing effect. When the nozzle 5 needs to be continuously sealed, since the adjusting tube 6 is threadedly connected to the nozzle 5, the position of the sealing sleeve 7 and the water inlet groove 11 on the nozzle 5 can be changed. When the sealing sleeve 7 contacts the fitting sleeve 14, the sealing sleeve 7 completely closes the water inlet groove 11, thereby completing the sealing process and then completing the adjustment process.

[0041] To achieve effective lubrication, add a lubrication mechanism, see Figure 1-Figure 5 The lubrication mechanism includes a spiral blade 29, a friction ring 30, a motor 31, a connecting plate 32 and a ball 33. The spiral blade 29 is provided with a friction ring 30, and the friction ring 30 is rotatably connected to the inner wall of the spray tube 2. A plurality of connecting plates 32 are provided, and the plurality of connecting plates 32 are respectively connected to the motor 31 and the inner wall of the spray tube 2. The extended end of the motor 31 is connected to the spiral blade 29. A rotating groove 34 is provided on the outer wall of the friction ring 30. The ball 33 is rotatably connected to the rotating groove. 34, a plurality of annular sleeves 35 are equidistantly arranged on the outer wall of the spray tube 2, an oil storage tube 36 is slidably arranged in each annular sleeve 35, a plurality of elastic sheets 37 are equidistantly arranged on the lower end surface of the oil storage tube 36, a ball groove 38 is provided in the oil storage tube 36, the ball 33 is rotatably connected in the ball groove 38, a plurality of diffusion grooves 39 are equidistantly provided in the ball groove 38, a through hole 40 is provided in the oil storage tube 36, the through hole 40 is connected to the plurality of diffusion grooves 39, and an internal The groove 41 and the through hole 40 are connected to the inner groove 41 respectively. A sealing head 42 is threadedly provided on each inner groove 41, and the sealing head 42 is fitted on the oil storage pipe 36. A plurality of transverse holes 43 are equidistantly provided on the side wall of the annular sleeve 35. A transverse rod 44 is slidably provided in each transverse hole 43. A follower frame 45 is provided on every two transverse rods 44. A tension spring 46 is provided on each follower frame 45. The plurality of tension springs 46 are connected to the side wall of the annular sleeve 35 respectively. The oil storage pipe 36 is provided with a plurality of transverse holes 43. A one-way groove 47 is provided on the side wall of the tube 36, and the transverse rod 44 is stuck in the one-way groove 47. A follower rod 48 is provided on each follower frame 45. A disengagement sleeve 49 is slidably provided on the side wall of the annular sleeve 35, and a reducing sleeve 50 is provided on the lower end surface of the disengagement sleeve 49. The follower rod 48 is slidably connected to the reducing sleeve 50. A plurality of guide grooves 51 are provided on the side wall of the annular sleeve 35, and a guide strip 52 is provided on the inner wall of the disengagement sleeve 49, and the guide strip 52 is slidably connected in the guide groove 51.

[0042] Working principle: when the spiral blade 29 rotates, the ball 33 rotates and connects to the ball groove 38, and the ball 33 rotates and connects to the rotating groove 34. When the friction ring 30 rotates accordingly, the friction of the friction ring 30 can be reduced by the rotation of the ball 33. Since the corresponding lubricating oil can be put into the internal groove 41 and then sealed by the sealing head 42, the lubricating oil can flow into the multiple diffusion grooves 39 through the through hole 40. Therefore, the lubricating oil can flow onto the surface of the ball 33 through the diffusion groove 39, and then penetrate into the rotating groove 34 through the ball 33, so that the friction between the two can be reduced. Then the lubricating oil will flow between the friction ring 30 and the spray pipe 2, further reducing the friction between the two, thereby ensuring the use effect.

[0043] When the ball 33 needs to be replaced after long-term use, first, push the release sleeve 49 and then the multiple reducing sleeves 50 move accordingly, then the follower rod 48 slides along the reducing sleeve 50, thereby pulling the multiple follower frames 45 outward, and then the tension spring 46 is stretched, and then the transverse rod 44 is pulled outward to release the connection between it and the one-way groove 47. At this time, the oil storage tube 36 can be pulled out, and the multiple elastic sheets 37 can be expanded outward due to the setting of the multiple elastic sheets 37, and then the ball 33 is taken out and replaced with a new ball 33, and then the oil storage tube 36 is directly inserted into the annular sleeve 35. Due to the setting of the one-way groove 47, it can be easily inserted, thereby completing the clamping process.

[0044] See also Figure 1 In order to realize multi-directional rotation, a rotating mechanism is added, which includes a support leg 53, a socket sleeve 54, a rotating shaft 55 and a hydraulic cylinder 56. The support leg 53 is installed on the base 1, and the socket sleeve 54 is installed on the support leg 53. The rotating shaft 55 is installed on the side wall of the spray pipe 2. The rotating shaft 55 is rotatably connected to the socket sleeve 54. One end of the hydraulic cylinder 56 is rotatably connected to the base 1, and the protruding end of the hydraulic cylinder 56 is connected to the spray pipe 2.

[0045] Working principle: When it is necessary to adjust the angle of the spray tube 2 to adapt to different dust reduction areas, first start the hydraulic cylinder 56. Since the two ends of the hydraulic cylinder 56 are respectively rotatably connected to the base 1 and the spray tube 2, the rotating shaft 55 on the spray tube 2 can be driven to rotate along the receiving sleeve 54, and then its position can be adjusted, thereby changing the area of ​​spray dust reduction and ensuring the dust reduction effect.
