Description

Technical Field

[0001] This utility model relates to the field of dust suppressant spraying technology, and more specifically, it relates to a dust suppressant spraying device. Background Technology

[0002] Coal and sand transported in the wind easily generate large amounts of dust, polluting the environment and posing safety hazards. Dust suppressant solutions involve spraying the agent onto the material surface. Utilizing its wetting and adhesive properties, it forms a sealed film, acting like a "dust-locking net," directly suppressing dust at its source and achieving clean operations.

[0003] The existing dust-sealant spraying equipment still has the following problems when in use: The existing spraying devices have fixed nozzles with slight manufacturing tolerances in their internal flow channels and outlet diameters. During synchronous spraying, these differences result in varying amounts of dust suppressant sprayed per unit time from each nozzle, causing patchy coverage in some areas of the material fall zone while others are under-covered, severely impacting the uniformity and overall effectiveness of the dust suppression layer. Because the nozzle installation position and spray angle are fixed, the coverage area and spray pattern are also locked. Under constant flow, the density of dust suppressant distribution within a fixed area cannot be changed, making it impossible to flexibly adjust the spraying strategy based on actual conditions such as pile height and wind speed. This prevents dynamic optimization of dust suppressant distribution, leading to resource waste and reduced effectiveness.

[0004] In view of this, we propose a dust suppression spraying device for dust sealing agents. Utility Model Content

[0007] The present invention is further configured such that both the inlet pipe and the guide pipe are flexible tubes.

[0008] The present invention is further configured such that the adjusting structure includes a sliding ring, the sliding ring is slidably connected to the connecting pipe, and the sliding ring is fixedly connected to a second fixed seat distributed circumferentially.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a dust suppression spraying device for dust sealing agents, which has the following beneficial effects: 1. This utility model uses a motor-driven belt mechanism to synchronously rotate all connecting pipes and nozzles in a circumferential direction, upgrading traditional fixed-point spraying to dynamic sweeping spraying. This effectively integrates the uneven coverage caused by differences in flow rate among the nozzles, ensuring that the dust-suppressing agent is evenly distributed across the entire working surface, thus improving the uniformity of the dust-suppressing layer and the overall dust-suppressing effect.

[0015] 2. This utility model controls the lifting and lowering of the sliding ring to synchronously drive all swing rods and nozzles to open or close. This structure enables precise and flexible control of the spray coverage area, allowing a single device to adapt to material piles or work areas of different sizes and shapes. It optimizes the distribution density of dust suppressant while ensuring coverage, thus enhancing the applicability and economy of the equipment.

[0016] 3. This utility model integrates the vertical height adjustment of the lifting frame with the horizontal spray width adjustment of the nozzles, forming a three-dimensional and flexible spraying system. Operators can remotely control the electric push rod and motor according to on-site conditions to quickly and coordinately adjust the spraying height and coverage area. This integrated and automated design reduces reliance on manual operation and improves the response speed and accuracy to complex operational needs. Attached Figure Description

[0022] Please see Figures 1-5 A dust suppression spraying device for dust sealing agent includes a lifting frame 1. A crossbeam 2 is fixedly connected to the movable part of the lifting frame 1. Multiple connecting pipes 3 are rotatably connected to the crossbeam 2. Connecting nozzles 4 are rotatably connected to the top of the connecting pipes 3. The multiple connecting nozzles 4 are all fixedly connected and connected to an inlet pipe 5. Fixed seats 6 are circumferentially evenly distributed and fixedly connected to the connecting pipes 3. A swing rod 7 is hinged to the fixed seat 6. A nozzle 8 is fixedly connected to the lower end of the swing rod 7. A guide pipe 9 is fixedly connected and connected to the connecting pipe 3. The connecting pipe 3 is provided with an adjustment structure. A driving structure is provided on the crossbeam 2. Both the inlet pipe 5 and the guide pipe 9 are made of flexible hoses.

[0023] Please see Figure 2 and Figure 4 The adjustment structure includes a sliding ring 10, which is slidably connected to the connecting pipe 3. The sliding ring 10 is fixedly connected to two fixed seats 11 that are evenly distributed in the circumferential direction. The swing rod 7 is fixedly connected to a fixed seat 12. The fixed seat 12 and the adjacent fixed seat 11 are hinged together by a hinge rod 13. Two pulleys 14 are fixedly connected to the connecting pipe 3.

[0024] Please see Figures 3-5 The drive structure includes a motor 15, which is fixedly connected to the crossbeam 2. The output end of the motor 15 is fixedly connected to a pulley 16. A belt 17 is wound between the pulley 14 and the adjacent pulley 14. A belt 17 is wound between the pulleys 14 on two adjacent connecting pipes 3. A sliding ring 10 is rotatably connected to a connecting ring 18. An electric push rod 19 is fixedly connected to the crossbeam 2. A connecting plate 20 is fixedly connected to the telescopic end of the electric push rod 19. The connecting plate 20 is fixedly connected to the connecting ring 18.

[0025] The working principle of this utility model: During use, the height of the crossbeam 2 is adjusted by controlling the lifting frame 1, and then the sealing agent is pumped into the liquid inlet pipe 5. The sealing agent enters the connecting pipe 3 through the connecting nozzle 4, and then enters the nozzle 8 through the liquid guide pipe 9. Finally, it is sprayed out from the nozzle 8 in an atomized state. When working, the motor 15 is started, and the output shaft of the motor drives the adjacent connecting pipes 3 to rotate through the pulley 16 and belt 17. The connecting pipes 3 are driven to rotate through the pulley 14 and belt 17. All five connecting pipes 3 rotate around the crossbeam 2. The connecting pipes 3 drive the swing rod 7 and the nozzle to rotate around the circumference through the fixed seat 6, thereby improving the uniformity of the sprayed sealing agent.

[0026] During the above process, if it is necessary to change the range of the dust sealant spray, the electric push rod 19 is activated. The telescopic end of the electric push rod 19 drives the connecting plate 20 to move upward. The connecting plate 20 drives the sliding ring 10 to move upward along the connecting pipe 3 through the connecting ring 18. The sliding ring 10, through the cooperation of the fixed seat 2 11, the hinge rod 13 and the fixed seat 3 12, drives the swing rod 7 to rotate around the fixed seat 1 6. At this time, the four adjacent nozzles 8 move away from each other, thereby changing the range of the dust sealant sprayed by the nozzles 8 and improving the applicability of this device. Conversely, when the telescopic end of the electric push rod 19 is controlled to drive the connecting plate 20 to move downward, the swing rod 7 swings downward along the fixed seat 1 6, and the four nozzles 8 move closer to each other.
