Description

Technical Field

[0001] The present invention relates to the technical field of atomized dust suppression, and particularly to a dust suppression system for port material transportation. Background Art

[0002] During the transportation of port materials, a large amount of dust is usually generated. In order to reduce the air pollution caused by dust and ensure the physical health of the staff, it is usually necessary to carry out dust reduction treatment during the material transportation process. The traditional dust reduction treatment usually adopts the method of spraying water for dust reduction. However, due to the large particle size of water droplets, when contacting with dust, it is easy to occur that the water droplets and dust particles cannot be effectively combined, resulting in poor dust reduction effect. Moreover, a large amount of water spraying will increase the humidity of the materials, affecting the subsequent production process. For example, in coal transportation, excessive water spraying will increase the water content of coal, reduce the calorific value of coal, and may also cause corrosion of transportation equipment.

[0003] At the same time, for some simple spray devices, the atomization effect is unstable and the atomization range is small, which is difficult to meet the dust suppression requirements in some large-scale operation scenarios.

[0004] As disclosed in the Chinese patent with the patent publication number CN117163693A, a dust suppression unloading system is disclosed, which includes a unloading trolley. The unloading trolley is provided with a first dust suppression device for suppressing dust in the throwing area of the belt conveyor, a second dust suppression device for suppressing dust in the falling area, a third dust suppression device for suppressing dust inside the corridor, and a water supply device. The first dust suppression device, the second dust suppression device, and the third dust suppression device can work independently and are all connected to the water supply device.

[0005] Although multiple dust suppression devices are provided, the overall shape of the spray heads of the dust suppression devices is fixed, the spray effect is single, and the spray range is determined by the initial nozzle installation shape. Only by increasing the number and installation position of the spray devices to improve the dust suppression effect, resulting in unsatisfactory overall use and easy waste of a large amount of water resources.

[0016] Advantages of the present invention: 1. The dust suppression system for port material conveying uses an upper atomization component and a lower atomization component distributed vertically, with the rotation directions of the upper atomization component and the lower atomization component being opposite. It uses a number of atomizing nozzles with different rotation directions for atomizing dust suppression, improving the fluidity of the steam mist in the air and ensuring the combination effect of the steam mist and the dust in the air. At the same time, the rotation speeds of the upper rotating ring and the lower rotating ring are adapted to the flow rate of the material in the receiving pipe and the falling pipe. When the material flow rate is fast, the rotation speeds of the upper rotating ring and the lower rotating ring are fast. Then, under the action of centrifugal force, the coverage range of the steam mist sprayed by the atomizing nozzles increases, avoiding the problem that the dust impact force is large due to the fast material flow rate, resulting in the dust exceeding the coverage of the steam mist. When the material flow rate is slow and the dust is concentrated, the steam mist sprayed by the atomizing nozzles is kept concentrated. When the material flow rate is fast and the dust diffusion range is large, the diffusion range of the steam mist is increased, enabling the diffusion of the steam mist to adapt to the diffusion of the dust, thereby effectively ensuring the dust suppression effect during material conveying, reducing dust flying, and ensuring the health of the staff.

[0017] 2. The dust suppression system for port material conveying sets an upper atomization component and a lower atomization component in a vertically stratified manner, and uses the upper atomization component and the lower atomization component to distribute sprays with alternately misaligned spray diffusion directions, reasonably arranging different atomizing nozzles, thereby effectively ensuring the diffusion range and coverage effect of the steam mist, effectively ensuring the combination effect of the steam mist and the dust, and ensuring the dust suppression efficiency and dust suppression effect during the material conveying process.

[0018] 3. The dust suppression system for port material conveying, through the layout setting of the atomizing nozzles of the upper rotating ring and the lower rotating ring, when the atomizing nozzles reach the maximum deflection state, the atomizing nozzles outside the upper rotating ring are in a fully unfolded state, and the upward deflection angle of the atomizing nozzles outside the lower rotating ring is half of the upward deflection angle of the atomizing nozzles outside the upper rotating ring. At the same time, the atomizing nozzles outside the lower rotating ring are in an alternately upward deflection state. Therefore, at this time, the top atomizing nozzles are in a fully unfolded state, half of the bottom atomizing nozzles are in a semi-unfolded state, and half are in the nozzle downward state, thereby further ensuring the diffusion range and coverage effect of the steam mist, effectively ensuring the combination effect with the air dust, and ensuring the dust suppression efficiency.

[0019] 4. The dust suppression system for port material conveying, through the cooperation of the travel switch and the electromagnetic push rod, when the material flow rate increases, the upward deflection angle of the atomizing nozzles increases, and at the same time, the rotation speed of the atomizing nozzles increases. And when the upward deflection angle of the atomizing nozzles increases, the flow rate of the steam mist sprayed by the atomizing nozzles increases. Thus, when the material flow rate increases, the flow rate of the steam mist sprayed by the atomizing nozzles increases synchronously, and at the same time, the coverage range of the sprayed steam mist and the fluidity of the sprayed steam mist increase synchronously, thereby achieving the effect of adapting to the material conveying flow rate, ensuring both the dust suppression effect during material conveying and the flexibility of atomizing dust suppression, reducing waste of resources, and improving the overall dust suppression efficiency and dust suppression effect.

[0022] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Please refer to Figure 1 - Figure 10 , a dust suppression system for port material transportation, including a gantry 1. The gantry 1 includes a receiving pipe 2 and a blanking pipe 3. Dust suppression mechanisms 4 are arranged outside both the receiving pipe 2 and the blanking pipe 3. The dust suppression mechanism 4 includes an atomization mechanism 41, a driving mechanism 42, and a dust blocking sheet 43. The dust blocking sheet 43 is installed on the side of the pipe orifice of the receiving pipe 2 and the blanking pipe 3, and the dust blocking sheet 43 is located below the atomization mechanism 41; The atomization mechanism 41 includes an upper atomization component 411 and a lower atomization component 412 distributed up and down. The upper atomization component 411 includes an upper shunt ring 4111 fixedly connected to the outside of the receiving pipe 2 and the blanking pipe 3. An upper rotating ring 4112 is rotatably connected to the outside of the upper shunt ring 4111. The lower atomization component 412 includes a lower shunt ring 4121 fixedly connected to the outside of the receiving pipe 2 and the blanking pipe 3. A lower rotating ring 4122 is rotatably connected to the outside of the lower shunt ring 4121; A number of atomizing nozzles 413 are arranged outside both the upper rotating ring 4112 and the lower rotating ring 4122. The driving mechanism 42 includes a driving impeller 421 rotatably connected inside the receiving pipe 2 and the blanking pipe 3. A transmission worm 422 is fixedly connected to the shaft part of the driving impeller 421. A transmission component 424 is arranged outside the transmission worm 422. The transmission worm 422 drives the upper rotating ring 4112 and the lower rotating ring 4122 to rotate through the transmission component 424; The upper shunt ring 4111 and the upper rotating ring 4112 are in communication with each other. The upper rotating ring 4112 and the atomizing nozzles 413 are in communication. The lower shunt ring 4121 and the lower rotating ring 4122 are in communication with each other. The lower rotating ring 4122 and the atomizing nozzles 413 are in communication.

[0024] The receiving pipe 2 and the blanking pipe 3 are respectively arranged at the ship and port positions. The working forms of the dust suppression mechanisms 4 of the receiving pipe 2 and the blanking pipe 3 are the same. The difference lies in the installation of the driving mechanism 42. When the materials in the receiving pipe 2 and the blanking pipe 3 flow, the installed driving mechanism 42 can drive the atomization mechanism 41 to work, and the working processes of the atomization mechanisms 41 of the receiving pipe 2 and the blanking pipe 3 are the same.

[0025] Reference Figures 5 - 7 Figures 5 - 7 During the material conveying process, when the conveyed material passes through the material receiving pipe 2 and the blanking pipe 3, the flowing material drives the driving impeller 421 to rotate. The driving impeller 421 drives the transmission worm 422 to rotate. The transmission worm 422 drives the upper rotating ring 4112 and the lower rotating ring 4122 to rotate respectively through the transmission assembly 424. The upper rotating ring 4112 and the lower rotating ring 4122 rotate in opposite directions. At the same time, both the upper atomizing assembly 411 and the lower atomizing assembly 412 spray atomized gas outward through the atomizing nozzles 413 for dust suppression operation.

[0026]

[0026] Through the upper atomizing assembly 411 and the lower atomizing assembly 412 distributed up and down, and the upper atomizing assembly 411 and the lower atomizing assembly 412 rotate in opposite directions, atomizing dust suppression is carried out by using a number of atomizing nozzles 413 with different rotation directions to improve the fluidity of the mist in the air and ensure the combination effect of the mist and the dust in the air. At the same time, the rotation speeds of the upper rotating ring 4112 and the lower rotating ring 4122 are adapted to the flow speed of the material in the material receiving pipe 2 and the blanking pipe 3. When the material flow speed is fast, the rotation speeds of the upper rotating ring 4112 and the lower rotating ring 4122 are fast. Then, under the action of centrifugal force, the coverage range of the mist sprayed by the atomizing nozzles 413 increases, avoiding the problem that the dust impact force is large due to the fast material flow speed, resulting in the dust exceeding the mist coverage. When the material flow speed is slow and the dust is concentrated, the mist sprayed by the atomizing nozzles 413 is kept concentrated. When the material flow speed is fast and the dust diffusion range is large, the diffusion range of the mist is increased, so that the diffusion of the mist can adapt to the diffusion of the dust, thereby effectively ensuring the dust suppression effect during material conveying, reducing dust flying, and thus ensuring the health of the staff.

[0027] Reference Figure 2 Figure 2 In an alternative embodiment: An air compressor 5 and a water tank 6 are further provided outside the dust suppression mechanism 4. An electric control cabinet 7 for power supply is provided outside the air compressor 5 and the water tank 6. An electric control cabinet 7, a pressure tank 8 and a filter 9 are sequentially provided outside the air compressor 5. A water pump 10 and a water purifier 11 are sequentially provided outside the water tank 6. An air delivery pipe 51 for sequentially connecting and communicating is provided between the air compressor 5, the electric control cabinet 7, the pressure tank 8 and the filter 9. A water delivery pipe 61 for sequentially connecting and communicating is provided between the water tank 6, the water pump 10 and the water purifier 11. The output ends of the air delivery pipe 51 and the water delivery pipe 61 are provided with a dry fog machine 12. The dry fog machine 12 is fixedly connected with an air pipe joint 52 and a water pipe joint 62 respectively through the air delivery pipe 51 and the water delivery pipe 61. The air pipe joint 52 and the water pipe joint 62 are both communicated with the upper flow dividing ring 4111 and the upper rotating ring 4112.

[0028] It should be noted that a dust suppression system is composed of a dust suppression mechanism 4, an air compressor 5, an air delivery pipe 51, an air pipe joint 52, a water tank 6, a water delivery pipe 61, a water pipe joint 62, an electric control cabinet 7, a pressure tank 8, a filter 9, a water pump 10, and a water purifier 11, where: The air compressor 5 provides compressed air for the system; The pressure tank 8 is used to store compressed air and stabilize the air pressure; The dry fog machine 12 is used to distribute compressed air and water in proportion and then deliver them to the atomizing nozzles 413; The water tank 6 is used to provide a water source; The filter 9 is used to filter impurities in the water to prevent the atomizing nozzles 413 from being blocked; The electric control cabinet 7 is used to supply power to the dust suppression system to ensure the stable operation of the dust suppression system.

[0029] Embodiment 2: Refer to Figures 3 - 7 , on the basis of Embodiment 1, further, the inner ring of the upper rotating ring 4112 is fixedly connected with an upper gear ring 4115. The transmission assembly 424 includes a driven worm gear 4241 meshed and connected with the transmission worm 422. The transmission assembly 424 further includes a first driving gear 4242. The first driving gear 4242 is coaxially and fixedly connected with the driven worm gear 4241. The first driving gear 4242 is meshed and connected with the upper gear ring 4115. The first driving gear 4242 drives the upper rotating ring 4112 to rotate outside the upper flow dividing ring 4111 through the upper gear ring 4115.

[0030] The inner ring of the lower rotating ring 4122 is fixedly connected with a lower gear ring 4125. The transmission assembly 424 further includes a second driving gear 4243. The second driving gear 4243 and the first driving gear 4242 are connected by a set of meshing gears. The rotation direction of the second driving gear 4243 is opposite to that of the first driving gear 4242. The second driving gear 4243 is meshed and connected with the lower gear ring 4125. The second driving gear 4243 drives the lower rotating ring 4122 to rotate reversely outside the lower flow dividing ring 4121 through the lower gear ring 4125.

[0031] It should be noted that air and water enter the upper flow dividing ring 4111 and the lower flow dividing ring 4121 through the air pipe joint 52 and the water pipe joint 62 respectively, and then enter the upper rotating ring 4112 and the lower rotating ring 4122 from the upper flow dividing ring 4111 and the lower flow dividing ring 4121 respectively, and then are ejected through their respective atomizing nozzles 413.

[0032] Among them, during the material flow process, the driving impeller 421 is driven to rotate. The driving impeller 421 drives the driven worm wheel 4241 to rotate through the transmission worm 422. The driven worm wheel 4241 drives the first driving gear 4242 to rotate. The first driving gear 4242 drives the upper rotating ring 4112 to rotate outside the upper flow dividing ring 4111 through the upper gear ring 4115. The upper rotating ring 4112 drives the atomizing nozzles 413 outside it to rotate.

[0033] At the same time, the first driving gear 4242 drives the second driving gear 4243 to rotate in the reverse direction through the gear set. The second driving gear 4243 drives the lower rotating ring 4122 to rotate in the reverse direction with the upper rotating ring 4112 through the lower gear ring 4125. Then, the atomizing nozzles 413 of the upper rotating ring 4112 and the atomizing nozzles 413 of the lower rotating ring 4122 rotate in the reverse direction, and at the same time, the steam mist is sprayed while rotating, and the diffusion directions of the upper and lower steam mists are alternately offset.

[0034] By setting the upper atomizing assembly 411 and the lower atomizing assembly 412 which are arranged in upper and lower layers, and using the upper atomizing assembly 411 and the lower atomizing assembly 412 to distribute the sprays with alternately offset diffusion directions, the different atomizing nozzles 413 are reasonably arranged, thereby effectively ensuring the diffusion range and coverage effect of the steam mist, effectively ensuring the combination effect of the steam mist and the dust, and ensuring the dust suppression efficiency and dust suppression effect during the material conveying process.

[0035] Embodiment 3: Refer to Figures 2 - 6 and Figure 10 On the basis of Embodiment 2, further, the atomizing mechanism 41 further includes a lifting bracket 414 which is slidably connected to the receiving pipe 2 and the blanking pipe 3. The upper atomizing assembly 411 further includes an upper pressing ring 4114 which is rotatably connected to the lifting bracket 414. A plurality of upper adjusting tooth rods 4113 are slidably connected to the outside of the upper rotating ring 4112. The plurality of upper adjusting tooth rods 4113 are all fixedly connected to the bottom of the upper pressing ring 4114. A deflection tooth groove 4131 is formed on the outside of the atomizing nozzle 413. The plurality of upper adjusting tooth rods 4113 and the deflection tooth groove 4131 are all meshed and connected, and the atomizing nozzle 413 is rotatably connected to the upper rotating ring 4112. An electromagnetic push rod 44 for controlling the up and down movement of the lifting bracket 414 is arranged outside the lifting bracket 414. When the upper adjusting tooth rod 4113 moves downward, the upper adjusting tooth rod 4113 drives the atomizing nozzle 413 meshed with it to deflect upward.

[0036] It should be noted that the electromagnetic push rod 44 is fixedly installed outside the receiving pipe 2 and the blanking pipe 3. The electromagnetic push rod 44 is used to push the lifting bracket 414 to slide up and down outside the receiving pipe 2 and the blanking pipe 3, and the lifting bracket 414 drives the upper pressing ring 4114 to slide up and down.

[0037] Specifically, when the electromagnetic push rod 44 drives the lifting bracket 414 to move downward, the lifting bracket 414 drives the upper pressing ring 4114 to move downward, the upper pressing ring 4114 drives a plurality of upper adjusting toothed rods 4113 to move downward, and the upper adjusting toothed rods 4113 drive the atomizing nozzle 413 to deflect upward through the deflection tooth groove 4131.

[0038] Reference Figure 6 , in an optional embodiment: A plurality of lower adjusting toothed rods 4123 are slidably connected to the outside of the lower rotating ring 4122. The tops of the plurality of lower adjusting toothed rods 4123 are fixedly connected to a lower pressing ring 4124. A return spring 4126 is arranged between the lower pressing ring 4124 and the lower rotating ring 4122. The plurality of lower adjusting toothed rods 4123 are alternately distributed at intervals outside the atomizing nozzle 413. The atomizing nozzle 413 is meshed and connected to the external lower adjusting toothed rods 4123 through the deflection tooth groove 4131. The atomizing nozzle 413 is rotatably connected to the outside of the lower rotating ring 4122. When the lower adjusting toothed rod 4123 moves downward, the lower adjusting toothed rod 4123 drives the meshed atomizing nozzle 413 to deflect upward.

[0039] Specifically, when the lower pressing ring 4124 moves downward, the lower pressing ring 4124 drives the lower adjusting toothed rod 4123 to move downward. The lower adjusting toothed rod 4123 drives the atomizing nozzle 413 to deflect upward through the deflection tooth groove 4131, and at this time, the atomizing nozzles 413 outside the lower rotating ring 4122 deflect upward alternately.

[0040] Reference Figure 5 and Figure 6 , in an optional embodiment: The bottom of the upper adjusting toothed rod 4113 is fixedly connected to a connecting ring 4127. A plurality of connecting rollers 4128 are arranged at the bottom of the connecting ring 4127. The connecting rollers 4128 are located directly above the lower pressing ring 4124. The maximum stroke of the lower adjusting toothed rod 4123 is half of the maximum stroke of the upper adjusting toothed rod 4113.

[0041] It should be noted that since the maximum stroke of the lower adjusting toothed rod 4123 is half of the maximum stroke of the upper adjusting toothed rod 4113, when the upper pressing ring 4114 moves downward to half of its stroke, the upper adjusting toothed rod 4113 drives the connecting ring 4127 and the connecting rollers 4128 to abut against the top of the lower pressing ring 4124. Then, when the upper pressing ring 4114 continues to move downward, the upper pressing ring 4114 and the lower pressing ring 4124 move downward synchronously. At this time, the atomizing nozzles 413 outside the upper rotating ring 4112 and the lower rotating ring 4122 deflect upward synchronously.

[0042] When reaching the maximum deflection state, the atomizing nozzles 413 outside the upper rotating ring 4112 are in a fully deployed state. The atomizing nozzles 413 outside the lower rotating ring 4122 are deflected upward by an angle that is half of the upward deflection angle of the atomizing nozzles 413 outside the upper rotating ring 4112. At the same time, the atomizing nozzles 413 outside the lower rotating ring 4122 are in an alternating upward deflection state. Therefore, at this time, the top atomizing nozzles 413 are in a fully deployed state, and half of the bottom atomizing nozzles 413 are in a semi-deployed state while the other half are in a state where the nozzles face downward, thereby further ensuring the diffusion range and coverage effect of the steam mist, effectively ensuring the combination effect with air dust, and ensuring the dust suppression efficiency.

[0043] Example 4: Refer to Figures 8 - 10 , further based on Example 3, a connecting shaft tube 4132 is rotationally connected to the shaft portion of the atomizing nozzle 413. An atomizing spray head 4133 is fixedly connected to the outside of the atomizing nozzle 413. An adjusting mechanism 4134 for controlling the flow rate is provided between the atomizing nozzle 413 and the connecting shaft tube 4132. The adjusting mechanism 4134 includes a deflecting disk 41341 fixedly connected to the atomizing nozzle 413 and a positioning disk 41342 fixedly connected to the connecting shaft tube 4132. An adjusting block 41343 is movably connected between the deflecting disk 41341 and the positioning disk 41342.

[0044] It should be noted that the adjusting block 41343 is used to adjust the size of the communication port between the connecting shaft tube 4132 and the atomizing spray head 4133, and the flow rate of the atomizing spray head 4133 is adjusted by adjusting the size of the communication port.

[0045] Among them, the connecting shaft tube 4132 is fixedly connected to the upper rotating ring 4112 and the lower rotating ring 4122.

[0046] Refer to Figure 9 , specifically, when the atomizing nozzle 413 deflects upward, the atomizing nozzle 413 drives the deflecting disk 41341 to rotate. Through the cooperation of the deflecting disk 41341 and the positioning disk 41342, the adjusting block 41343 is driven to deflect outward, so that the communication port between the atomizing spray head 4133 and the connecting shaft tube 4132 is enlarged, and the amount of steam mist sprayed by the atomizing spray head 4133 increases. Therefore, the upward deflection amplitude of the atomizing nozzle 413 is positively correlated with the amount of steam mist sprayed.

[0047] Refer to Figure 10, wherein, a push - adjusting assembly 423 is arranged outside the driving impeller 421. A driving shaft 4231 is rotatably connected inside the push - adjusting assembly 423. The driving shaft 4231 is fixedly connected to the shaft end of the driving impeller 421. A push rod 4232 is movably connected to the outside of the driving shaft 4231. A fixed shaft 4235 is movably connected to the outside of the push rod 4232. A travel switch 4236 is fixedly connected inside the push - adjusting assembly 423. The fixed shaft 4235 is rotatably connected to the travel switch 4236. A connecting rod 4233 penetrates through the fixed shaft 4235 and abuts against the outside of the travel switch 4236. The travel switch 4236 is electrically connected to the electromagnetic push rod 44. A "herringbone" connecting rod 4233 is hinged between the fixed shaft 4235 and the push rod 4232. A counterweight ball 4234 is fixedly connected to the outer side end of the connecting rod 4233.

[0048] It should be noted that an accelerator is arranged between the driving shaft 4231 and the push rod 4232. The accelerator includes, but is not limited to, a planetary gear transmission. Wherein, the driving shaft 4231 is connected to the outer gear ring of the planetary gear transmission, and the push rod 4232 is movably connected to the sun gear shaft part of the planetary gear transmission.

[0049] Specifically, when the driving impeller 421 drives the driving shaft 4231 to rotate, the driving shaft 4231 drives the push rod 4232 to rotate through the accelerator. The push rod 4232 drives the connecting rod 4233 and the counterweight ball 4234 to rotate. Due to the centrifugal force of the counterweight ball 4234, under the action of the counterweight ball 4234, the connecting rod 4233 drives the push rod 4232 to move towards the travel switch 4236, so that the push rod 4232 presses the travel switch 4236.

[0050] Among them, the travel switch 4236 is electrically connected to the electromagnetic push rod 44. The pressing travel of the travel switch 4236 is proportional to the driving travel of the electromagnetic push rod 44. Therefore, when the logistics flow rate increases, the rotation speed of the driving impeller 421 increases, the rotation speed of the driving shaft 4231 driven by the driving impeller 421 increases, so that the centrifugal force of the counterweight ball 4234 increases. Finally, the travel of the push rod 4232 pressing the travel switch 4236 increases. Correspondingly, the travel of the electromagnetic push rod 44 driving the lifting bracket 414 to move downward increases.

[0051] Through the cooperation of the travel switch 4236 and the electromagnetic push rod 44, when the material flow rate increases, the upward offset angle of the atomizing nozzle 413 increases, and at the same time, the rotation speed of the atomizing nozzle 413 increases. And when the upward offset angle of the atomizing nozzle 413 increases, the sprayed aerosol flow rate of the atomizing nozzle 413 increases. Thus, when the material flow rate increases, the sprayed aerosol flow rate of the atomizing nozzle 413 increases synchronously, and at the same time, the coverage range of the sprayed aerosol and the fluidity of the sprayed aerosol increase synchronously, so as to achieve the effect of adapting to the material conveying flow rate, ensuring both the dust suppression effect during material conveying and the flexibility of atomizing dust suppression, reducing waste of resources, and improving the overall dust suppression efficiency and dust suppression effect.

The scope of the present invention is defined by the appended claims and their equivalents.
