Description

Technical Field

[0001] This utility model relates to the field of workshop dust reduction technology, specifically to a fogging dust reduction device. Background Technology

[0002] Fog dust suppression is an advanced dust removal system based on high-pressure micro-mist technology. This system includes a water treatment unit, a power unit, a transmission unit, and a fog dust suppression unit. The water treatment unit removes impurities, calcium and magnesium ions, and microorganisms from the water, preventing clogging of the atomizing nozzles and water mist crystallization, thus ensuring the long-term stable operation of the fog system. The core of the power unit is a high-pressure pump, controlled by a frequency converter to automatically adjust the water supply and pressure according to dust concentration. Safety valves and pressure gauges ensure stable and safe power output monitoring. The transmission unit uses universal joints, tees, and other connectors to form a grid-like pipeline network to deliver water to the atomizing nozzles. The core of the fog dust suppression unit is the atomizing nozzle, which atomizes the water delivered to the nozzle and sprays the atomized water mist, creating a drifting water mist. Because most water mist particles are less than 10 micrometers in diameter, when these particles collide with various floating dust particles in the air, they quickly adhere to these particles, significantly increasing the mass of the originally lightweight dust particles. Ultimately, the dust particles settle under gravity, rapidly reducing the concentration of suspended dust in the air and meeting dust removal requirements. Simultaneously, because water mist particles are micrometer-sized, their evaporation surface area is thousands of times larger than that of ordinary water droplets. These tiny droplets absorb a large amount of heat from the environment during evaporation, significantly lowering the ambient temperature in the workshop and creating a cool working environment.

[0003] To facilitate dust removal in the workshop, the atomizing nozzles should be installed at a high point. While using a long, rod-shaped base to mount the nozzles at a high point offers some flexibility by moving the base, it increases the nozzles' purchase cost and occupies workshop space, affecting flow efficiency. To optimize space utilization, the atomizing nozzles are directly mounted on the workshop's ceiling beams. This involves first mounting the nozzles onto clamps, then securing the clamps to the ceiling beams, thus avoiding any impact on space utilization. However, because the atomizing nozzle is installed on one side of the clamp, the weight distribution on both sides of the clamp is severely uneven. During the clamp assembly process, the torsional torque generated by the shift in the clamp's center of gravity is clearly felt, thus burdening the clamp assembly operation. Simultaneously, because the workshop's roof beam is located at a high position, installers need to climb to work at heights, making it difficult for them to maintain a stable working posture. Combined with the clamp's center of gravity shift, this makes the entire installation process extremely difficult. Furthermore, since the atomizing nozzle is mounted on the clamp, maintenance or movement of the nozzle requires first removing the clamp from the roof beam, which is also difficult due to the uneven weight distribution. In addition, the installation height of the atomizing nozzle directly affects its water mist effect and dust removal efficiency. To facilitate adjustment of the atomizing nozzle's position, a telescopic adjustment mechanism is usually installed between the atomizing nozzle and the clamp, allowing the atomizing nozzle to move relative to the clamp. However, since the water supply pipeline is connected to the atomizing nozzle, adjusting the height inevitably causes pulling or squeezing of the pipeline, thus affecting the connection between the pipeline and the atomizing nozzle. Therefore, there are shortcomings in the assembly and movement of the atomizing nozzle. By improving the misting dust suppression system, the assembly of the atomizing nozzle can be made easier, and the position of the atomizing nozzle can be adjusted to meet the actual needs of modern workshops for misting dust suppression. Summary of the Invention

A support arm is provided between the bracket and the support tube, and the support tube is connected to the support arm. An assembly mechanism is provided between the support arm and the bracket. The assembly mechanism includes two support blocks provided on the side of the bracket near the support arm, and an n-shaped support frame provided between the two support blocks. The support frame is installed on the end of the support arm near the bracket. Support grooves are provided on the inner side of the two support blocks, and the support grooves are fitted onto the support frame. The support grooves extend from the top of the support block to the bottom of the support block. The two sides of the support frame are in contact with the bracket and the support blocks, respectively.

[0006] Preferably, the support arm is provided with two support plates. One side of each support plate is in contact with the two side walls of the support arm, and the other side of each support plate is connected to the support tube. One side of each support plate and the support arm is provided with a sleeve hole. A third bolt is fitted into the sleeve hole. The diameter of the screw of the third bolt matches the diameter of the sleeve hole. A first nut is threaded onto the third bolt. The two support plates are clamped and fixed to the support arm by the third bolt and the first nut.

[0007] Preferably, each of the two support plates has a through hole on one side, which is located outside the support arm. A fourth bolt is fitted inside the through hole, and the diameter of the bolt's thread matches the diameter of the through hole. A second nut is threaded onto the fourth bolt. Two arc-shaped fixing plates are provided on the side of the fourth bolt away from the support arm. The two fixing plates are respectively fitted on both sides of the support tube and installed on one end of the two support plates. The two fixing plates are pressed and fixed to the support tube by the nut of the fourth bolt and the second nut.

[0008] Preferably, the connecting pipe adopts a T-shaped tee fitting. The vertical pipe of the connecting pipe is provided with a connector, which is installed on the first end of the connecting pipe. One end of the fixing pipe is fitted inside the horizontal pipe of the connecting pipe. The fixing pipe extends out from the second end of the connecting pipe. A fixing cap is threaded onto the third end of the connecting pipe. A fixing ring is fitted onto the end of the fixing pipe away from the atomizing nozzle. The fixing ring is installed on the fixing pipe. The outer diameter of the fixing ring is not greater than the inner diameter of the connecting pipe. The outer diameter of the fixing pipe matches the inner diameter of the supporting pipe. A through groove is opened on the side wall of the fixing pipe, and the through groove is located inside the connecting pipe.

[0009] Preferably, the inner cavity of the sealing tube has a stepped structure. The inner diameter of the sealing tube on the side away from the support tube matches the outer wall diameter of the fixed tube. The inner diameter of the sealing tube on the side away from the support tube is not greater than the inner diameter of the sealing tube on the side closer to the support tube. Two pressure rings are provided in the sealing tube on the side closer to the support tube, and the sealing ring is located between the two pressure rings. The two pressure rings contact the end of the support tube and the corner of the sealing tube, respectively. Flanges are respectively fitted on the sealing tube and the support tube. The flanges are integral with the sealing tube or the support tube, and the sealing tube and the support tube are connected through the flanges.

[0010] Preferably, a reinforcing tube is threaded onto the second bolt, and the reinforcing tube is installed on the outer side of the bracket. The two sides of the support arm are in contact with the sides of the two support blocks respectively. The top of the support block is inclined and has a guide groove. The guide groove gradually descends along the direction close to the support arm and is connected to the support groove.

[0011] The beneficial effects of this utility model are as follows: First, the utility model connects the connecting pipe and the atomizing nozzle through a fixed pipe, allowing the water supplied to the connecting pipe to be transferred to the atomizing nozzle, thus creating a mist effect in the workshop. The sealing ring and sealing pipe create a dynamic seal for the fixed pipe, preventing water from flowing out from the gap between the connecting pipe and the fixed pipe, and allowing the fixed pipe to move the atomizing nozzle relative to the connecting pipe. First bolts positioned away from the sealing ring and support pipe clamp and fix the fixed pipe to the sealing pipe, allowing for adjustment of the atomizing nozzle's position and the creation of various mist effects. Furthermore, the utility model uses an N-shaped bracket structure, enabling the bracket to be quickly mounted on the workshop's ceiling beam. Tightening the second bolts threaded onto the bracket secures it to the ceiling beam. An assembly mechanism between the support arm and the bracket facilitates the assembly of the atomizing nozzle onto the bracket, allowing for rapid assembly of the atomizing nozzle after the bracket is installed on the ceiling beam, thus reducing the burden of loading and unloading the atomizing nozzle.

[0012] Secondly, the present invention can adjust the rotation of the support plate relative to the support arm by means of the third bolt and the first nut, thereby facilitating the adjustment of the orientation of the atomizing nozzle. The fourth bolt and the second nut can clamp and fix the support tube between the two fixing plates. The fixing plate adopts an arc-shaped structure so that the fixing plate wraps around the support tube, so that the support tube can be assembled onto the support plate.

[0013] Furthermore, this invention employs a tee fitting for the connecting pipe, allowing the first end of the connecting pipe to connect to the water delivery pipeline via a connector. A fixed pipe extending from the second end of the connecting pipe connects to the atomizing nozzle, facilitating water delivery to the nozzle for atomization. A threaded cap at the third end of the connecting pipe seals the third end, preventing the fixed pipe from protruding during use. For maintenance, the cap is removed to access the fixed pipe from the third end. The outer diameter of the fixing ring at the end of the fixed pipe is not less than the inner diameter of the support pipe, preventing the end of the fixed pipe away from the atomizing nozzle from entering the support pipe. Moreover, the sealing pipe uses a stepped structure to create a limiting space for the sealing ring. Two pressure rings compress the sealing ring, confining it within the sealing pipe and ensuring a tight seal. In addition, this utility model reinforces the threaded connection between the second bolt and the bracket by setting a reinforcing tube, thereby firmly clamping the bracket to the top beam of the workshop. The guide groove opened by the set support block guides the support arm to be inserted between the two support blocks, thereby improving the assembly efficiency of the support arm.

[0020] like Figures 1 to 5 As shown, a fogging dust suppression device includes a fixed pipe 1 and an atomizing nozzle 2 mounted on the fixed pipe 1. The atomizing nozzle 2 is installed at one end of the fixed pipe 1, and its inner cavity is connected to the inner cavity of the fixed pipe 1. A connecting pipe 3, a support pipe 4, and a sealing pipe 5 are sequentially mounted on the fixed pipe 1 from the direction away from the atomizing nozzle 2 to the direction closer to the atomizing nozzle 2. The sealing pipe 5 is connected to the connecting pipe 3 through the support pipe 4. One end of the fixed pipe 1 is located inside the connecting pipe 3, and the connecting pipe 3 is connected to the atomizing nozzle 2 through the fixed pipe 1. A sealing ring 6 is provided inside the sealing pipe 5. The sealing ring 6 is slidably and sealingly fitted onto the fixed pipe 1 to prevent water from leaking out from the gap between the sealing pipe 5 and the fixed pipe 1. The sealing ring 6 is located away from the support pipe 4. A first bolt 7 is provided on one side of the sealing tube 5, and a fixing hole is provided on the sealing tube 5. The fixing hole is threaded onto the first bolt 7, and the fixing tube 1 is clamped to the sealing tube 5 by the first bolt 7. The length of the fixing tube 1 is not less than the sum of the lengths of the connecting tube 3, the support tube 4, and the sealing tube 5, so as to facilitate the adjustment of the length of the fixing tube 1 extending out of the sealing tube 5, so as to adjust the position of the atomizing nozzle 2, thereby meeting the needs of misting. A water pipe made of elastic material is installed on the side of the connecting tube 3 away from the support tube 4. The water pipe is connected to a pressurized water source through a valve. By controlling the valve, water is transported through the water pipe to the connecting tube 3, and then through the fixing tube 1 to the atomizing nozzle 2. After passing through the atomizing nozzle 2, the internal liquid is atomized. The water flow is converted into a water mist spray to create a water mist in the workshop. An N-shaped bracket 8 is installed on one side of the support pipe 4. A threaded hole is opened on the side of the bracket 8 away from the support pipe 4, and a second bolt 9 is threaded into this hole. The bracket 8 is mounted on the assembly beam in the workshop, and the second bolt 9 is tightened to clamp and fix the bracket 8 onto the beam. A support arm 10 is provided between the bracket 8 and the support pipe 4, and the support pipe 4 is connected to the support arm 10. An assembly mechanism is provided between the support arm 10 and the bracket 8. The assembly mechanism includes two support blocks 11 located on the side of the bracket 8 near the support arm 10, and an N-shaped support frame 12 located between the two support blocks 11. The support frame 12 is installed on one end of the support arm 10 near the bracket 8. The inner sides of the two support blocks 11 are respectively provided with support grooves 13. The support grooves 13 are fitted onto the support frame 12. The support grooves 13 are opened from the top of the support block 11 to the bottom of the support block 11. The two sides of the support frame 12 are in contact with the bracket 8 and the support block 11 respectively. By inserting the two sides of the support frame 12 into the support grooves 13 from the top of the two support blocks 11 respectively, the support frame 12 can be quickly and securely assembled between the support block 11 and the bracket 8. When it is necessary to remove the support arm 10 from the bracket 8, the support frame 12 is pushed out from the support grooves 13 from the bottom to the top, so as to quickly remove the support arm 10 equipped with the atomizing nozzle 2 from the bracket 8.

[0021] In this embodiment, the support arm 10 is provided with two support plates 14. One side of each support plate 14 is in contact with the two side walls of the support arm 10, and the other side of each support plate 14 is connected to the support tube 4. One side of each support plate 14 and the support arm 10 is provided with a sleeve hole, and a third bolt 15 is fitted into the sleeve hole. The diameter of the screw of the third bolt 15 matches the diameter of the sleeve hole. A first nut 16 is threaded onto the third bolt 15. The two support plates 14 are clamped and fixed to the support arm 10 by the third bolt 15 and the first nut 16. By controlling the third bolt 15 and the first nut 16, the rotation position of the fixed tube 1 can be adjusted, thereby facilitating the adjustment of the orientation of the atomizing nozzle 2 to meet the dust suppression requirements.

[0022] Specifically, each of the two support plates 14 has a through hole on one side, which is located outside the support arm 10. A fourth bolt 17 is fitted inside the through hole, and the diameter of the bolt 17 matches the diameter of the through hole. A second nut 18 is threaded onto the fourth bolt 17. Two arc-shaped fixing plates 19 are provided on the side of the fourth bolt 17 away from the support arm 10. The two fixing plates 19 are respectively fitted on both sides of the support tube 4 and installed on one end of the two support plates 14. The two fixing plates 19 are pressed and fixed to the support tube 4 by the nut of the fourth bolt 17 and the second nut 18, thereby assembling the support tube 4 onto the support plate 14.

[0023] Please refer to it again. Figure 1 , 2In section 4, the connecting pipe 3 adopts a T-shaped tee fitting, which is assembled from a horizontal pipe and a vertical pipe. The top of the vertical pipe is installed in the middle of the horizontal pipe, so that the vertical pipe is connected to the inner cavity of the horizontal pipe through the middle of the horizontal pipe. The first end of the connecting pipe 3 is the bottom end of the vertical pipe. The second end and the third end of the connecting pipe 3 are located at the two ends of the horizontal pipe, respectively. The vertical pipe of the connecting pipe 3 is provided with a connector 20, which is installed on the first end of the connecting pipe 3. The connection between the connecting pipe 3 and the water pipe is completed by interfering with one end of the water pipe onto the connector 20. One end of the fixing pipe 1 is fitted into the horizontal pipe of the connecting pipe 3. The fixing pipe 1 extends out from the second end of the connecting pipe 3. The third end of the connecting pipe 3 is threaded with a fixing cap 21. The third end of the connecting pipe 3 is sealed by the fixing cap 21 to prevent the water delivered to the connecting pipe 3 from leaking out through the third end of the connecting pipe 3. The fixing cap 21 is also used to restrict the movement range of the fixing pipe 1. The fixing pipe 1 is located away from the horizontal pipe. A fixing ring 22 is fitted to the end of the atomizing nozzle 2. The fixing ring 22 is installed on the fixing tube 1. The outer diameter of the fixing ring 22 is not greater than the inner diameter of the connecting tube 3. The outer diameter of the fixing tube 1 matches the inner diameter of the support tube 4. Thus, the fixing ring 22 is used to constrain the movement range of the fixing tube 1 to prevent the end of the fixing tube 1 away from the atomizing nozzle 2 from entering the support tube 4. When the fixing tube 1 needs to be maintained, the fixing cover 21 is removed first. The fixing tube 1 is then pulled out from the third end of the connecting tube 3 for maintenance. It should also be noted that the outer surface of the fixing cover 21 is provided with an anti-slip layer to facilitate the screwing of the fixing cover 21. A through groove 23 is opened on the side wall of the fixing tube 1. The through groove 23 is located inside the connecting tube 3 so that water can be transported to the fixing tube 1 through the connecting tube 3. To prevent the through groove 23 from entering the sealing tube 6, the distance from the end of the through groove 23 away from the fixing ring 22 to the fixing ring 22 is not greater than the length of the support tube 4.

[0024] In this embodiment, the inner cavity of the sealing tube 5 has a stepped structure. The inner diameter of the sealing tube 5 on the side away from the support tube 4 matches the outer wall diameter of the fixing tube 1. The inner diameter of the sealing tube 5 on the side away from the support tube 4 is not greater than the inner diameter of the sealing tube 5 on the side closer to the support tube 4. Two pressure rings 24 are provided inside the sealing tube 5 on the side closer to the support tube 4. The sealing ring 6 is located between the two pressure rings 24. The two pressure rings 24 are in contact with the end of the support tube 4 and the corner of the sealing tube 5, respectively. The sealing tube 5 and the support tube 4 are connected in a stepped structure. Flanges 25 are fitted onto pipes 4. Flanges 25 are integral with sealing pipes 5 or support pipes 4. Sealing pipes 5 and support pipes 4 are connected by flanges 25. The flanges 25 on sealing pipes 5 and support pipes 4 are clamped and fixed together by bolts and nuts to assemble sealing pipes 5 and support pipes 4. This facilitates the assembly and disassembly of sealing pipes 5 and support pipes 4, and makes it easier to maintain the sealing ring 6 and pressure ring 24 installed inside sealing pipes 5, as well as the sealing pipes 5 and support pipes 4.

[0025] Please refer to it again. Figure 2 The second bolt 9 is threaded with a reinforcing tube 26, which is installed on the outer side of the bracket 8 to reinforce the threaded connection between the second bolt 9 and the bracket 8, thereby firmly clamping the bracket 8 onto the roof beam of the workshop. The two sides of the support arm 10 are in contact with the sides of the two support blocks 11, so that the two support blocks 11 can constrain the two sides of the support arm 10, thereby reducing the swaying of the support arm 10. The top of the support block 11 is inclined with a guide groove 27, which gradually descends along the direction close to the support arm 10. The guide groove 27 is connected to the support groove 13 to guide the support arm 10 inserted between the two support blocks 11, thereby improving the assembly efficiency of the support arm 10.

[0026] The assembly method for this product is as follows: (e.g.) Figures 1 to 6As shown, firstly, the pressure ring 24 and sealing ring 6 are assembled inside the sealing tube 5, and the sealing tube 5 is assembled onto the end of the support tube 4 away from the connecting tube 3 using the flange 25. The fixing tube 1 is then inserted into the connecting tube 3 through its third end, and so on, through the second end of the connecting tube 3, into the support tube 4 and the sealing tube 5, until the fixing ring 22 enters the connecting tube 3, and the end of the fixing tube 1 away from the fixing ring 22 exits from the sealing tube 5. Next, the fixing cap 21 is screwed onto the third end of the connecting tube 3 to seal the third end of the connecting tube 3, preventing the fixing tube 1 from exiting from the third end of the connecting tube 3. Then, the connector 20 is installed on the first end of the connecting tube 3, and the atomizing nozzle 2 is installed on the end of the fixing tube 1 that exits from the sealing tube 5, thus completing the assembly of the connecting tube 3. Then, the two support plates 14 connected to the fixing plates 19 are installed on both sides of the support arm 10 using the third bolt 15 and the first nut 16. The support pipe 4 is clamped and fixed between the two fixing plates 19 by fitting the support pipe 4 between the two fixing plates 19 and tightening the fourth bolt 17 and the second nut 18. Next, the product is carried to a high place in the workshop to hang the bracket 8 on the workshop's roof beam. The bracket 8 is clamped and fixed on the workshop's roof beam by tightening the second bolt 9 on the reinforcing pipe 26. The support frame 12 is then fitted into the support groove 13 opened in the two support blocks 11 to assemble the support arm 10 onto the bracket 8. Finally, the angle between the fixing plate 19 and the support arm 10 and the position of the fixing pipe 1 relative to the connecting pipe 3 are adjusted, and the first bolt 7, the third bolt 15, and the first nut 16 are tightened to fix the fixing pipe 1. The water delivery pipe is then arranged, and one end of the pipe is installed on the connector 20 to complete the assembly of the product.

[0027] In this embodiment, the connecting pipe 3 and the atomizing nozzle 2 are connected by the fixed pipe 1, so that the water delivered to the connecting pipe 3 is transferred to the atomizing nozzle 2, so that the atomizing nozzle 2 can be used to create a fog effect in the workshop. The fixed pipe 1 is dynamically sealed by the sealing ring 6 and the sealing pipe 5, which not only prevents the water from flowing out from the gap between the connecting pipe 3 and the fixed pipe 1, but also allows the fixed pipe 1 to drive the atomizing nozzle 2 to move relative to the connecting pipe 3. The fixed pipe 1 can be clamped and fixed to the sealing pipe 5 by the first bolts set at the sealing ring 6 away from the support pipe 4, so that the position of the atomizing nozzle can be adjusted to create a variety of fog effects. Furthermore, this utility model adopts an n-shaped structure for the bracket 8, which allows the bracket 8 to be quickly mounted on the roof beam of the workshop. By tightening the second bolt on the threaded sleeve of the bracket 8, the bracket 8 can be clamped and fixedly assembled on the roof beam. An assembly mechanism is provided between the support arm 10 and the bracket 8 to facilitate the assembly of the atomizing nozzle 2 onto the bracket 8. This allows the assembly of the atomizing nozzle 2 to be completed quickly after the bracket 8 is installed on the roof beam, thereby reducing the burden of loading and unloading the atomizing nozzle 2.
