Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, and in particular to a spray atomizing device for dust suppression. Background Technology

[0002] Port terminals, especially those handling coal, mineral powder, and construction ash and gravel, generate dust during loading, transportation, unloading, and other operations, causing air pollution. To combat this dust, port workers typically spray water on the terminal area periodically to absorb dust, and further reduce dust by installing direct-stream water spray guns along the perimeter walls. However, these existing methods have limitations. Direct-stream water spray guns have limited coverage, making it difficult to effectively spray and suppress dust in loading and unloading areas, leaving workers still affected by the dust. Furthermore, dragging water hoses to spray water can easily disrupt loading and unloading operations. To address the aforementioned issues, it was discovered that a variable-speed worm gear automatic rotating spray gun, disclosed in Chinese Invention Patent Publication No. CN117181478A, can be applied to dust suppression operations at docks. By fixing this prior art at the edge of the loading and unloading area, it can achieve reciprocating left and right swinging to form a fan-shaped spray area, effectively spraying and wetting the dock site.

[0003] However, the following problems still exist in the application of the above-mentioned existing technologies: the nozzles used in the existing technologies are relatively simple, and the water column shape is only cut by the diverting rod to achieve atomization. This method of atomization is incomplete and it is difficult to form an atomized water shield. Dust easily drifts to the area near the spray gun. These areas cannot be covered due to the structural problems of the spray gun, resulting in incomplete dust suppression. Utility Model Content

[0004] The purpose of this invention is to solve the problem that dust suppression spray guns used in the prior art are unable to handle dust in dead-angle areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A dust suppression spray atomizing device includes a worm gear spray gun, a first nozzle and a second nozzle on the worm gear spray gun, a turbine at the output end of the second nozzle, a support on the worm gear spray gun, a baffle on the support, the baffle being a semi-circular curved surface, a water guide groove on the baffle, a water collection tank below the water guide groove, a sleeve on the water collection tank, the sleeve sliding relative to the water collection tank, a piston rod inside the sleeve, the piston rod passing through the water collection tank and the two being sleeved together, a spring between the piston rod and the water collection tank, and a plurality of spray heads on the water collection tank.

[0006] Preferably, the bottom of the sleeve is also provided with a drainage hole.

[0007] Preferably, a direct current spray water gun is fitted onto the first nozzle.

[0008] Preferably, a universal rotating device is provided between the DC spray water gun and the first nozzle. The universal rotating device includes a fixed sleeve, which is sleeved on the first nozzle. A movable sleeve is hinged to the fixed sleeve and is sleeved with the DC spray water gun.

[0009] Preferably, the movable sleeve is further provided with an adjustment device, the adjustment device including a first adjustment rod and a second adjustment rod, the first adjustment rod being hinged to the worm gear spray gun, the first adjustment rod being in contact with the DC spray water gun, the first adjustment rod being hinged to the second adjustment rod, and the second adjustment rod being slidable relative to the worm gear spray gun.

[0010] Preferably, the outer wall of the sleeve is provided with a plurality of drainage grooves, the number of which is the same as the number of rows of the spray heads.

[0011] The beneficial effects proposed by this utility model are as follows: During the liquid flow operation of the worm gear spray gun, a straight stream of water is ejected from the first nozzle, while a small portion of the water source is output from the second nozzle. At this time, the water stream output from the second nozzle acts on the turbine, causing the turbine to start rotating and driving the worm gear spray gun to rotate. For the working principle of the turbine driving the worm gear spray gun to rotate, please refer to the worm gear spray gun of model DLPL50 produced by Xuzhou Delong Sprinkler Equipment Co., Ltd. In this process, the straight stream of water driving the turbine to rotate will be splashed outward by the reverse force of the turbine, which can wet the circumferential area with the turbine as the axis, and realize the wet dust suppression treatment of the spray dead corner of the first nozzle.

[0012] However, in the above process, since the rotational speed of the turbine is affected by the water pressure intensity ejected from the second nozzle, when the water pressure is low, the centrifugal reaction force generated by the turbine will be smaller and unable to cover a larger area. Therefore, it is necessary to separately pressurize the water pressure of the spray. The baffle is fitted around the turbine to block splashing water from the second nozzle and collects it through the water guide channel into the water collection tank. When the water in the collection tank accumulates to a certain weight, the weight of the water presses on the piston rod, driving it downwards and simultaneously moving the sleeve downwards. As the sleeve moves downwards, the spray head gradually opens, and water is ejected through the spray head under water pressure. During this process, the piston rod compresses the spring until the water in the collection tank gradually decreases, and the pressure on the piston rod also gradually decreases. At this time, the spring gradually releases the elastic force stored during compression. When the elastic force of the spring is greater than the weight pressure of the water, the spring drives the piston rod to move upwards until it returns to its original position. During this process, the sleeve moves upwards synchronously, finally closing the spray head and entering the next spray cycle. Through the above, the efficient utilization of the turbine-driven water source is achieved, and the water pressure range of the spray head is fixed by the water collection bucket, which can cover the annular area centered on the water collection bucket to moisten and suppress dust, improve the dust suppression effect, and reduce the spray dead angle of the worm gear spray gun.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1 to 6 A dust suppression spray atomizing device includes a worm gear spray gun 1, a first nozzle 2 and a second nozzle 3 on the worm gear spray gun 1, a turbine 4 at the output end of the second nozzle 3, a bracket 5 on the worm gear spray gun 1, a baffle 6 on the bracket 5, the baffle 6 being a semi-circular curved surface, a water guide groove 7 on the baffle 6, a water collection tank 8 below the water guide groove 7, a sleeve 9 fitted on the water collection tank 8, the sleeve 9 sliding relative to the water collection tank 8, a piston rod 10 inside the sleeve 9, the piston rod 10 passing through the water collection tank 8 and the two being sleeved together, a spring 11 between the piston rod 10 and the water collection tank 8, and a plurality of spray heads 12 on the water collection tank 8. Specifically, during the liquid flow operation of the worm gear spray gun 1, a straight stream of water is sprayed out from the first nozzle 2, while a small portion of the water source is output from the second nozzle 3. At this time, the water stream output from the second nozzle 3 acts on the turbine 4, causing the turbine 4 to start rotating and driving the worm gear spray gun 1 to rotate. For the working principle of the turbine 4 driving the worm gear spray gun to rotate, refer to the worm gear spray gun 1 of model DLPL50 produced by Xuzhou Delong Sprinkler Irrigation Equipment Co., Ltd. In this process, the straight stream of water driving the turbine 4 to rotate will be splashed outward by the reverse force of the turbine 4, which can wet the circumferential area with the turbine 4 as the axis, and realize the wet dust suppression treatment of the spray dead corner of the first nozzle 2.

[0017] However, in the above process, the rotational speed of the turbine 4 is affected by the water pressure intensity ejected from the second nozzle 3. When the water pressure is low, the centrifugal reaction force generated by the turbine 4 will be smaller, and it will not be able to cover a larger area. Therefore, it is necessary to separately increase the water pressure of the spray. That is, the baffle 6 is set around the turbine 4. The baffle 6 is used to block the splashing of the water column output from the second nozzle 3 and collects it through the water guide channel 7 into the water collection tank 8. When the water in the water collection tank 8 accumulates to a certain weight, the weight of the water will press on the piston rod 10 and drive the piston rod 10 to move downward, synchronously driving the sleeve 9 to move downward. As the sleeve 9 gradually moves downward, the spray head 12 gradually opens. Under the action of water pressure, the water source passes through the... As the spray head 12 is ejected, the piston rod 10 compresses the spring 11 until the water in the water collection tank 8 gradually decreases, and the pressure acting on the piston rod 10 also gradually decreases. At this time, the spring 11 gradually releases the elastic force stored during compression. When the elastic force of the spring 11 is greater than the weight pressure of the water, the spring 11 drives the piston rod 10 to move upward until it returns to its original position. During this process, the sleeve 9 moves upward synchronously, finally closing the spray head 12 and entering the next spray cycle. Through the above, efficient utilization of the water source driven by the turbine 4 is achieved, and the water pressure range of the spray head 12 is fixed by the water collection tank 8, which can cover the annular area centered on the water collection tank 8 to moisten and suppress dust, improve the dust suppression effect, and reduce the spray dead angle of the worm gear spray gun 1.

[0018] It should be noted that the spray head 12 has an inlet larger than an outlet. This structure facilitates the generation of higher water pressure, enabling the spray head 12 to output a high-pressure jet. This working principle is widely used in high-pressure water gun structures and is a common technique employed by those skilled in the art; the specific working principle will not be described in detail here.

[0019] Specifically, the bottom of the sleeve 9 is also provided with a drain hole 13. The drain hole 13 is used to drain water accumulated inside the sleeve 9. When the sleeve 9 slides relative to the water collecting tank 8, the inner wall of the sleeve 9 rubs against the outer wall of the water collecting tank 8, and water will flow into the sleeve 9. In order to reduce the risk of the spray head 12 malfunctioning due to the increased weight of the sleeve 9 caused by water accumulation inside the sleeve 9, the drain hole 13 can further moisten and suppress dust in the area at the bottom of the sleeve 9, thereby increasing the spraying area of ​​this device.

[0020] Specifically, a direct-flow spray water gun 14 is fitted onto the first nozzle 2. The preferred model of the direct-flow spray water gun 14 is a Norden 50 type internally recessed water gun, which can spray both dense water streams (direct current) and mist-like water streams, and has an on / off function. When the ground surface is covered with thick dust, the direct-flow spray water gun 14 uses a direct-flow water jet mode. This mode can quickly output water and act rapidly on the ground, wetting it and reducing the risk of dust accumulation. When dust gradually appears, the direct-flow spray water gun 14 switches to a mist-like water stream mode, generating a mist-like water stream to form a water mist barrier, reducing the speed of dust spread.

[0021] Specifically, a universal rotating device is provided between the DC spray water gun 14 and the first nozzle 2. The universal rotating device includes a fixed sleeve 15, which is sleeved on the first nozzle 2. A movable sleeve 16 is hinged to the fixed sleeve 15 and is sleeved with the DC spray water gun 14. Since the water jet from the DC spray water gun 14 is parabolic, in order to achieve maximum coverage and adjustment within the area, its elevation angle needs to be adjusted, i.e., adjusted through the universal rotating device. During this process, the elevation angle of the movable sleeve 16 is adjustable through its hinge with the fixed sleeve 15.

[0022] Specifically, the movable sleeve 16 is also provided with an adjustment device, which includes a first adjustment rod 17 and a second adjustment rod 18. The first adjustment rod 17 is hinged to the worm gear spray gun 1 and abuts against the DC spray water gun 14. The first adjustment rod 17 is hinged to the second adjustment rod 18, and the second adjustment rod 18 can slide relative to the worm gear spray gun 1. When it is necessary to adjust the angle of the DC spray gun 14, the second adjusting rod 18 is pushed to slide relative to the worm gear spray gun 1 and move towards the first adjusting rod 17. Since the first adjusting rod 17 is hinged to the worm gear spray gun 1, when the second adjusting rod 18 moves towards the first adjusting rod 17, it will drive the first adjusting rod 17 to rotate. At this time, the first adjusting rod 17 will apply a thrust to the DC spray gun 14, and by utilizing the hinge between the movable sleeve 16 and the fixed sleeve 15, the angle of the DC spray gun 14 can be adjusted as the first adjusting rod 17 rotates, realizing convenient adjustment of the elevation angle of the DC spray gun 14. In this process, the first adjusting rod 17 can also provide support for the positioning of the DC spray gun 14 after the angle adjustment, reducing the risk of angle deviation caused by instability when the DC spray gun 14 is working after the angle adjustment.

[0023] Furthermore, in order to improve the stability of the support provided by the first adjusting rod 17 to the DC spray gun 14, a plurality of second locking nuts 19 are provided on the second adjusting rod 18. The second locking nuts 19 are threadedly connected to the second adjusting rod 18. At the same time, different second locking nuts 19 act on the second adjusting rod 18 and the worm gear spray gun 1 respectively, forming a clamping force to clamp the second adjusting rod 18 and the worm gear spray gun 1 together, thereby locking the second adjusting rod 18.

[0024] Specifically, the outer wall of the sleeve 9 is provided with a plurality of drainage grooves 20, the number of which is the same as the number of rows of spray heads 12. The drainage grooves 20 are used to collect residual water stains from the spray heads 12, reducing water stains from seeping into the sleeve 9 and alleviating the problem of water accumulation inside the sleeve 9. At the same time, the drainage grooves 20 guide the accumulated water from the spray heads 12 to the bottom area of ​​the sleeve 9, which can moisten and suppress dust in the bottom area of ​​the sleeve 9, thereby increasing the spraying area of ​​the device, maximizing the utilization of water resources, and saving resources.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
