Description

Technical Field

[0001] The invention belongs to the technical field of atomizing nozzle equipment, and more specifically relates to a dust suppression atomizing device for long-distance and large-scale construction. Background Art

[0002] Water mist dust reduction is an effective air purification technology. It mainly captures dust particles in the air by spraying fine water mist, thereby reducing the dust concentration in the air and improving air quality. The working principle of water mist dust reduction is to use high-pressure atomization technology to spray water through high-pressure atomization equipment to produce fine water mist. These water mists collide with dust particles in the air to form larger water droplets. Due to the effect of gravity, these water droplets will fall to the ground with dust particles, thereby achieving the effect of dust reduction.

[0003] Water mist dust suppression equipment mainly includes high-pressure water pumps. The high-pressure water pump increases the water pressure to a certain level, and then atomizes the water into tiny water droplets through the atomizing nozzle. Water mist dust suppression technology has the advantages of simple operation, obvious effect, and low cost. It is widely used in places with large dust sources such as construction sites, mines, ports, chemical plants, and landfills.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.

[0018] Water mist dust suppression is an effective air purification technology that captures dust particles in the air by spraying fine water mist, thereby reducing dust concentration in the air and improving air quality. Near construction sites, vehicle-mounted water mist dust suppression equipment is usually used to spray water mist into the sky to prevent dust from damaging the air environment. However, existing water mist dust suppression equipment cannot take into account the range and distance of spraying water mist. For construction sites with large construction areas and wide dust areas, multiple water mist dust suppression equipment may be required to be distributed at multiple points and work simultaneously to meet the dust suppression requirements.

[0019] In order to solve the above problems, the purpose of the present invention is to provide a long-distance and large-scale construction dust suppression atomization device, which is used to form a long-distance and large-scale water mist at the construction site to suppress dust; the long-distance and large-scale construction dust suppression atomization device includes an air supply component for generating an airflow and a plurality of spray barrel devices, each spray barrel device includes a mixing channel 11 for mixing atomized water with the airflow, and an angle adjustment component for adjusting the spray angle of the water mist; The multiple spray tube devices can respectively control the distance and angle of the water mist spraying; the air supply assembly includes an air supply channel 12 and a blower device 13 arranged inside the air supply channel 12, and the blower device 13 generates an air flow in the air supply channel 12 by rotating blades; the mixing channel 11 is connected to the blower channel, and a water pipe 14 and an atomizing device capable of atomizing water are arranged on the side wall of the mixing channel 11, and the water pipe 14 is used to transport water into the mixing channel 11 and atomize the water; The angle adjustment component includes a fixed channel 21 with a fixed position and a movable channel 22 sleeved outside the fixed channel 21, and the movable channel 22 can be adjusted relative to the fixed channel 21; a plurality of linear drivers 23 are arranged between the movable channel 22 and the fixed channel 21, and the angle of the movable channel 22 can be adjusted by controlling the length of each linear driver 23 respectively; after the water mist passes through the fixed channel 21 and the movable channel 22, it is sprayed out from the end of the movable channel 22.

[0020] In this embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the air supply channel 12 is cylindrical, the blower 13 is a blade and a motor that drives the blade to rotate, the motor drives the blade to rotate and then forms an airflow in the air supply channel 12, and the airflow flows in the direction close to the angle adjustment component. The mixing channel 11 is connected to the air supply channel 12, the mixing channel 11 is cylindrical, the water pipe 14 passes through the side wall of the mixing channel 11, and the atomizing device can be set at the end of the water pipe 14 inside the mixing channel 11. The water pipe 14 is connected to a pressurized water source, which is changed into water mist by the atomizing device and then sprayed outward with the airflow.

[0021] The number of the spray tube devices is at least two, and the atomizing device of this embodiment includes three spray tube devices. In the specific implementation process, each spray tube device can be connected to an air supply assembly. Alternatively, multiple spray tube devices can be connected to one air supply assembly.

[0022] The fixed channel 21 is connected to the mixing channel 11 . The fixed channel 21 mainly serves to connect the movable channel 22 . A linear drive 23 is arranged between the fixed channel 21 and the movable channel 22 . A plurality of linear drives 23 are arranged around the movable channel 22 .

[0023] The linear drive 23 can be a connecting piece such as a hydraulic cylinder or a linear motor that can be extended or shortened; the fixed channel 21 is connected to the inner space of the movable channel 22 and is hingedly connected.

[0024] In some embodiments, the long-distance and large-scale construction dust suppression atomization device includes three nozzle devices, and the mixing channel 11 of each nozzle device is respectively connected to the air supply component; the airflow generated by the air supply component can evenly enter the three nozzle devices; the angle adjustment components of the three nozzle devices can respectively adjust the direction of the water mist sprayed by the nozzle device, and the air supply component can adjust the distance of the water mist sprayed, ultimately achieving the control of the water mist range and distance.

[0025] Each spray barrel device is controlled by a different linear drive 23. In the three spray barrel devices of this embodiment, three linear drives 23 are distributed around each spray barrel device. The two ends of the three linear drives 23 are respectively hinged to the fixed channel 21 and the movable channel 22. When each linear drive 23 is extended or shortened, the movable channel 22 can change its angle as the length of the three linear drives 23 connected to it changes.

[0026] When adjusting the angle, an external controller adjusts the lengths of the three linear actuators 23 . After the angle adjustment is completed, the lengths of all the linear actuators 23 are locked to fix the angle of the active channel 22 .

[0027] Furthermore, a circular channel 24 is provided outside the mixing channel 11, and a plurality of water pipes 14 are provided on the circular channel 24. The plurality of water pipes 14 are distributed in a circular shape on the side wall of the mixing channel 11; A water inlet 25 is provided on the annular channel 24, and the water inlet 25 is used to introduce pressurized water into the annular channel. The annular channel 24 passes the water into multiple water pipes 14, and the water pipes 14 pass through the side walls of the mixing channel 11 and enter the interior of the mixing channel 11; the water in the annular channel 24 flows into the water pipes 14 and after being atomized, forms water mist inside the mixing channel 11.

[0028] In this embodiment, a plurality of water pipes 14 are arranged outside the mixing channel 11, and the annular channel 24 connects these water pipes 14, and the annular channel 24 serves to connect the water source with the plurality of water pipes 14. The annular channel 24 is annular in shape, hollow inside, and the internal space is connected to the water pipe 14. A water inlet 25 is arranged on the annular channel 24, and the water inlet 25 is used to connect a pressurized water source, and a fixing member (not shown in the figure) that can connect a pipeline can be arranged on the water inlet 25. The external water source enters the annular channel 24 through the water inlet 25, and then flows into the plurality of water pipes 14, and the plurality of water pipes 14 can make the water mist inside the mixing channel 11 more evenly distributed.

[0029] Further, one end of the fixed channel 21 is connected to the mixing channel 11, and the fixed channel 21 is a rotating body with an arc-shaped cross-section, and the diameter of the center is larger than the diameters of the two ends; the inner wall shape of the connecting portion between the movable channel 22 and the fixed channel 21 is an arc-shaped shape matching the outer wall of the fixed channel 21, and the movable channel 22 is arranged on the side of the fixed channel 21 away from the mixing channel 11; A fixing ring 31 is also sleeved on the outside of the fixed channel 21, and the fixing ring 31 is arranged on a side of the fixed channel 21 close to the mixing channel 11; flange rings are respectively arranged on the sides of the fixing ring 31 opposite to the movable channel 22, and the fixing ring 31 and the movable channel 22 are connected through the flange ring and fasteners connecting the two flange rings; the connecting part of the fixing ring 31 and the movable channel 22 is located close to the center of the fixed channel 21.

[0030] In this embodiment, Figure 3 , Figure 4 as well as Figure 5 As shown, the fixed channel 21 is a rotating body with an arc-shaped cross section, and is cylindrical as a whole. The middle diameter is larger than the diameters at both ends. One end is connected to the mixing channel 11, and the other end is used to connect to the movable channel 22.

[0031] The connection between the mixing channel 11 and the fixed channel 21 matches the arc shape of the fixed channel 21, and the fixed ring 31 and the mixing channel 11 are sleeved outside the fixed channel 21 from both sides of the fixed channel 21; flange rings are respectively provided on the sides opposite to the movable channel 22, and the fixed ring 31 and the movable channel 22 are connected by the flange ring and the fasteners connecting the two flange rings. The movable channel 22 can be removed by removing the fasteners, and after the fixed ring 31 and the movable channel 22 are connected by the flange ring and the fasteners, the connection part has a spherical center. The spherical center of the connection part between the fixed ring 31 and the movable channel 22 is co-pointed with the spherical center of the fixed ring 31. Therefore, the fixed ring 31 and the movable channel 22 can rotate around the fixed channel 21.

[0032] Furthermore, a connecting seat 32 is respectively provided on the outer shell of the movable channel 22 and the mixing channel 11, and the linear drive 23 connects the connecting seat 32 of the movable channel 22 and the connecting seat 32 of the mixing channel 11; one end of the linear drive 23 is hinged to the connecting seat 32 on the movable channel 22, and the other end of the linear drive 23 is hinged to the connecting seat 32 of the mixing channel 11; The linear drive 23 includes a sleeved inner rod and an outer rod, which are respectively hinged to a connecting seat 32 on the active channel 22 and a connecting seat 32 of the mixing channel 11. The linear drive 23 can control the extension and retraction of the inner rod and the outer rod, and multiple linear drives 23 can control the angle of the active channel 22.

[0033] like Figure 5 As shown, this embodiment proposes a specific implementation method of connecting a linear drive 23 with a fixed channel 21 and a movable channel 22. The connecting seat 32 on the outer shell of the movable channel 22 and the mixing channel 11 is a hinge seat, which includes a hemispherical enclosure and a sphere arranged in the enclosure. The enclosure covers more than 50% of the surface area of ​​the sphere. One side of the enclosure is open, and the outer surface of the sphere contacts the inner surface of the enclosure, so the sphere will not fall from the opening of the enclosure. The sphere is connected to the linear drive 23 in the opening direction of the enclosure.

[0034] When the linear drive 23 is extended or retracted, the sphere and the surrounding member rotate relative to each other to accommodate the relative rotation between the linear drive 23 and the articulated seat when the linear drive 23 is extended or retracted.

[0035] The linear actuator 23 includes a sleeved inner rod and an outer rod, which are respectively hinged to the connection seat 32 on the movable channel 22 and the connection seat 32 of the mixing channel 11. The linear actuator 23 can control the extension and retraction of the inner rod and the outer rod. The linear actuator 23 can be a hydraulic cylinder, a linear motor or other connector that can be extended or shortened. The fixed channel 21 is connected to the inner space of the movable channel 22 and is hingedly connected. When adjusting the angle, the external controller adjusts the length of the three linear actuators 23. After the angle adjustment is completed, the lengths of all linear actuators 23 are locked to fix the angle of the movable channel 22.

[0036] Furthermore, the angle adjustment component is further provided with a range adjustment component at the end away from the air supply component, and the range adjustment component includes a plurality of blade units arranged in a circular ring, an opening and closing driving mechanism for controlling the opening and closing of the blade units, and a limit ring 41 for limiting the position of the blade units; The blade unit includes a blade bracket 42 and a blade body 43. The blade bracket 42 is hinged to the limiting ring 41, and the blade body 43 is connected to the blade bracket 42. The blade body 43 is arc-shaped. The blade body 43 of the blade unit is radially stacked with the blade body 43 of the adjacent blade unit. The blade bracket 42 can rotate around the hinge part between the blade bracket 42 and the limiting ring 41. The diameter of the end of the blade body 43 away from the air supply assembly can change with the rotation of the blade bracket 42, ultimately changing the distance and range of the water mist sprayed by the spray gun device. The opening and closing drive mechanism is used to adjust the angle of the blade bracket 42.

[0037] like Figure 6 , Figure 8 As shown, the air flow and water mist are sprayed out from the opening at one end of the active channel 22. The diameter of the opening can control the flow rate and range of the water mist spraying. A smaller opening will lead to a larger flow rate and a concentrated water mist spraying range; conversely, a larger opening will lead to a smaller flow rate and a wider water mist spraying range.

[0038] The size of the opening is controlled by the overlapping area of ​​the blade body 43 and the adjacent blade body 43. The proximal end of the blade bracket 42 is hinged to the limit ring 41, and the distal end of the blade bracket 42 is at the opening. The blade bracket 42 can rotate around the hinge. During the rotation, the distal ends of all blade brackets 42 can approach or move away from each other.

[0039] When the distal ends of all blade supports 42 move toward each other, the overlapping area between blade bodies 43 and adjacent blade bodies 43 increases, and the opening decreases. Conversely, when the distal ends of all blade supports 42 move toward each other, the overlapping area between blade bodies 43 and adjacent blade bodies 43 decreases, and the opening increases.

[0040] Further, the opening and closing driving mechanism includes a rotating ring 51 and a translation ring 52 connected by threads and an opening and closing driver driving the rotating ring 51 to rotate; a rotating slide groove 53 is provided on the outer side of the movable channel 22, and a rotation limiting slider 54 is provided on the rotating ring 51.

A translation limiting slider 56 is provided on the blade unit. The translation limiting slider 56 is arranged in the translation slot 55 to limit the translation ring 52 to only be able to translate along the axial direction of the active channel 22 but not to rotate. A step 61 is provided on the side of the blade bracket 42 close to the translation ring 52, and a plurality of connecting arms 62 are radially provided on the inner side of the translation ring 52, and these connecting arms 62 are respectively provided on both sides of each blade bracket 42, and two limiting columns 63 are respectively provided on each connecting arm 62, and the two limiting columns 63 are respectively provided on both sides of the step 61; the hinged part between the blade bracket 42 and the limiting ring 41 is on the inner side of the translation ring 52, and when the translation ring 52 moves, the limiting columns 63 move in the length direction of the blade bracket 42, and adjust the angle of the blade bracket 42 at the same time.

[0041] like Figure 6 , Figure 7 , Figure 8 as well as Fig.10 As shown, this embodiment proposes a specific implementation of an opening and closing drive mechanism, which includes a rotating ring 51 and a translation ring 52 connected by threads and an opening and closing driver that drives the rotating ring 51 to rotate; a rotating slot 53 is provided on the outside of the active channel 22, and a rotation limiting slider 54 is provided on the rotating ring 51. The rotation limiting slider 54 is arranged in the rotating slot 53, and the rotating ring 51 can only rotate along the axis of the active channel 22 but cannot translate. The rotating slot 53 in this embodiment surrounds the outer surface of the active channel 22, and the rotation limiting slider 54 is a bolt that passes through the rotating ring 51, and a matching nut is provided to fix the position of the bolt.

[0042] The rotation limiting slider 54 is disposed in the rotation slot 53 and can rotate freely. The side wall of the rotation slot 53 can block the axial movement of the rotating ring 51 .

[0043] like Figure 7 , Fig.10 As shown, the translation limiting slider 56 of this embodiment is an articulated seat between the blade bracket 42 and the limiting ring 41, a part of the articulated seat protrudes from the outer circumferential surface of the limiting ring 41, and a translation groove 55 whose position and width match the articulated seat is provided on the translation ring 52.

[0044] The rotating ring 51 and the translating ring 52 are connected by threads. When the rotating ring 51 rotates, the translating ring 52 is guided by the threads and can translate along the axis of rotation.

[0045] In some embodiments, the translational slide groove 55 and the translational limiting slider 56 may also be independent sliders and slide grooves in addition to the articulated seat.

[0046] like Fig. 9 As shown, a step 61 is provided on one side of the blade bracket 42 close to the translation ring 52. The blade bracket 42 is strip-shaped. The step 61 is on the outside of the blade bracket 42. A plurality of connecting arms 62 are radially provided on the inside of the translation ring 52. These connecting arms 62 are respectively provided on both sides of each blade bracket 42. Two limiting posts 63 are provided on each connecting arm 62. The two limiting posts 63 are respectively provided on both sides of the step 61. Four limiting posts 63 are provided around the step 61 of each blade bracket 42.

[0047] The hinged portion between the blade bracket 42 and the limiting ring 41 is on the inner side of the translation ring 52. When the limiting column 63 is close to the distal end of the blade bracket 42, the opening becomes larger; conversely, when the limiting column 63 is close to the proximal end of the blade bracket 42, the opening becomes smaller.

[0048] In some embodiments, the opening and closing driver is an electric motor and a gear 64 installed on the output shaft of the motor. A rack 65 is provided on the outer side of the rotating ring 51 at a position corresponding to the gear 64. When the motor rotates, the rotating ring 51 can be driven to rotate through the transmission of the gear 64 and the rack 65.

[0049] Furthermore, a flexible wind shielding ring 71 is provided inside the movable channel 22 and inside the blade unit, and the wind shielding ring 71 is used to prevent water mist from flowing from the gap between the hinge of the blade bracket 42 and the limiting ring 41 to the outside of the movable channel 22 .

[0050] In this embodiment, the wind shielding ring 71 may be a thin sheet-like component made of flexible and deformable plastic or rubber, and is used to close the gap between the hinge part of the blade bracket 42 and the limiting ring 41 .

[0051] Furthermore, the long-distance and large-scale construction dust suppression atomization device also includes a bracket assembly, and the bracket assembly is used to install the long-distance and large-scale construction dust suppression atomization device on other objects.
