Description

Technical Field

[0001] This invention relates to the field of environmental protection and dust control technology, and in particular to an intelligent dust control device for road and bridge construction. Background Technology

[0002] Dust pollution is one of the major environmental problems during road and bridge construction. Construction dust not only leads to a decline in air quality, but may also cause respiratory diseases for construction workers and surrounding residents. For dust control, existing technologies usually use dust suppression devices, especially the mainstream fugitive dust control equipment in industries such as mining, municipal construction, and building materials processing. The core of these devices is to generate droplets that are highly matched to the size of dust particles, adsorb and agglomerate dust particles to achieve natural settling, which is more than 70% more water-saving than traditional large-scale water spraying.

[0003] The intelligent fog cannon used in this system operates on the core logic of "air-driven high-pressure atomization + intelligent linkage control." It uses a strong airflow to precisely push micron-level water mist to dusty areas hundreds of meters away, automatically capturing and settling dust. It is currently the mainstream intelligent equipment for large-scale fugitive dust control in construction sites and mining enterprises. The high-pressure water supply system pressurizes the water source and sprays it out through a specially designed atomizing nozzle group. To increase its spraying range, a high-speed strong airflow is generated by a high-power axial flow fan to transport the atomized water droplets.

[0004] However, the nozzles are exposed to high dust environments for a long time. After the machine is shut down, dust accumulates directly at the nozzle, which affects the dust suppression spraying and cleaning work. It is also more troublesome to clean the impurities adhering to the nozzle. In addition, when road construction requires temporary repairs and maintenance of a large area, the nozzle of the fog cannon lacks an auxiliary diffusion component to meet its high-efficiency dust suppression requirements.

[0005] Therefore, this invention proposes an intelligent dust control device for road and bridge construction to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an intelligent dust control device for road and bridge construction to solve the problems mentioned in the background art.

The flow-expanding curved plate is located on one side of the lightweight support strip; The dust suppression spray mechanism also includes auxiliary components for supporting and driving the lightweight support strips.

[0008] Preferably, the first nozzle and the second nozzle are arranged in a ring at equal intervals; Furthermore, the annular diameter formed by the distribution of the first nozzle is larger than the annular diameter of the second nozzle.

[0009] Preferably, the connection structure includes a mating slot disposed at one end of the support piece and a mating insert disposed at one end of the connecting piece; The docking plug is inserted into the docking slot.

[0010] Preferably, the connection structure further includes a positioning slot disposed on the docking body and a screw hole disposed in the support piece and communicating with the docking slot; The screw hole body is provided with a positioning screw that is adapted to engage with the positioning slot.

[0011] Preferably, the bent portion and the baffle plate together form an L-shaped plate; A flow guide ramp is also provided on the bottom side surface of the baffle.

[0012] Preferably, the lightweight support strips are arranged in two sets at equal intervals in a ring, forming an inner ring lightweight support strip and an outer ring lightweight support strip; The support piece at the end of the inner ring lightweight support strip is higher than the support piece at the end of the outer ring lightweight support strip.

[0013] Preferably, the auxiliary component includes an inner blade that is fixedly connected to the inner ring lightweight support strip and an outer blade that is fixedly connected to the outer ring lightweight support strip; The auxiliary component also includes a rotating seat ring for mounting the inner and outer blades.

[0014] Preferably, two sets of rotating seat rings are provided on the inner side of the front end of the fog cannon barrel body. The inner blades are arranged in a ring at equal intervals on the inner side of the rotating seat ring away from the front end of the fog cannon barrel body, and the outer blades are arranged in a ring at equal intervals on the inner side of the rotating seat ring close to the front end of the fog cannon barrel body.

[0015] Preferably, the auxiliary component further includes a connecting ring disposed on the outer side of the rotating seat ring, and a limiting ring body is provided on the outer ring surface of the connecting ring; A first auxiliary ball bearing is equidistantly arranged on the outer ring surface of the rotating seat ring, and a second auxiliary ball bearing is equidistantly arranged on the outer ring surface of the limiting ring body.

[0016] Preferably, the auxiliary component further includes a receiving cavity for accommodating the placement of the limiting ring; The receiving cavity is formed by splicing two sets of loading frame rings. A fixing foot plate is fixedly installed on the outside of the loading frame rings. The fixing foot plate is fixed to the inner side wall of the front end of the fog cannon barrel body by screws.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This solution has two sets of annular nozzles at the front end of the main body of the spray device, namely the first nozzle in the outer ring and the second nozzle in the inner ring; the mist sprayed from the first nozzle and the second nozzle is used to suppress flying dust; the spraying distance of the mist is increased by using an axial flow conveyor fan, thereby improving the efficiency of dust suppression. Based on this, this solution sets a flow-expanding curved plate on the side wall of the lightweight support strip. When air is delivered by the axial flow conveying fan, the air delivered along the axis of the main body of the fog cannon is sprayed out from the front nozzle. During this process, when the air passes through the flow-expanding curved plate, it will guide part of the airflow to the direction of the first nozzle and the second nozzle, providing a diffusion and blowing effect for the mist sprayed from the first nozzle and the second nozzle, thereby increasing the range of mist spraying and having a positive effect on improving the efficiency of dust suppression. In addition, in order to further improve the dust suppression effect of spraying and the cleaning effect of the first and second nozzles, this solution uses auxiliary components to provide support and rotatability for the lightweight support strips. When the axial flow fan delivers air along the axis of the fog cannon body, the air body passes through the inner and outer blades that are arranged in an equidistant ring. The air body will drive the rotating seat ring where the two are located to rotate, which will in turn drive each lightweight support strip to make a circular motion, and finally drive the diffuser plate and the baffle plate to make a circular motion. During this process, the diffuser plate amplifies the airflow to increase the delivery range of the sprayed mist, thereby increasing the dust suppression range and better adapting to on-site construction needs. In addition, the guide ramp set at the bottom of the baffle plate also disperses and guides the sprayed mist when it passes the nozzle, which also plays a positive role in increasing the dust suppression range. The cleaning brushes can clean impurities on each nozzle. Attached Figure Description

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1 - Appendix Figure 12 An intelligent dust suppression device for road and bridge construction includes a support frame 1 and a fog cannon body 5; a moving wheel mechanism 2 is provided at the bottom of the support frame 1 and a water storage device 3 is provided on the support frame 1. The main body 5 of the fog cannon is mounted on the fog cannon support device 4 located on the support frame 1. A spray device body 8 is installed at the front nozzle of the fog cannon body 5, and an axial flow conveying fan 7 is installed at the rear nozzle of the fog cannon body 5. The water supply pipe 6 located on the water storage device 3 is connected to the spray device body 8. A first nozzle 81 and a second nozzle 82 are installed at the front of the spray device body 8. The dust suppression device also includes a spray dust suppression auxiliary mechanism installed inside the front nozzle of the fog cannon body 5.

[0022] Specifically, from the appendix Figure 3 - Appendix Figure 5 As shown, in this scheme, the first nozzle 81 and the second nozzle 82 are arranged in a ring at equal intervals; and the diameter of the ring formed by the distribution of the first nozzle 81 is larger than the diameter of the ring formed by the second nozzle 82.

[0023] That is, two sets of annular nozzles are set at the front end of the main body 8 of the spraying device, namely the first nozzle 81 in the outer ring and the second nozzle 82 in the inner ring; the mist sprayed from the first nozzle 81 and the second nozzle 82 is used to suppress dust; the axial flow conveying fan 7 is used to increase the spraying distance of the mist, thereby improving the efficiency of dust suppression.

[0024] Combined with the appendix Figure 6 - Appendix Figure 9 and appendix Figure 11 - Appendix Figure 12 As shown, the dust suppression auxiliary mechanism in this solution includes a lightweight support bar 901, a flow-expanding curved plate 902, and a baffle plate 906. A support piece 903 is provided at the front end of the lightweight support bar 901. The support piece 903 is connected to the connecting piece 904 through a connecting structure. A bending part 905 is provided at one end of the support piece 903. The bending part 905 is connected to the baffle plate 906. A cleaning brush body 908 is provided on the bottom side of the baffle plate 906. The flow-expanding curved plate 902 is provided on one side of the lightweight support bar 901.

[0025] The purpose of setting the diffuser plate 902 on the side wall of the lightweight support strip 901 is that when the axial flow fan 7 delivers air, the air delivered along the axis of the main body 5 of the fog cannon is sprayed out from the front nozzle. During this process, when the air passes through the diffuser plate 902, it will direct part of the airflow toward the first nozzle 81 and the second nozzle 82, providing a diffusion and blowing effect for the mist sprayed from the first nozzle 81 and the second nozzle 82, thereby increasing the spray range of the mist and having a positive effect on improving the efficiency of dust suppression.

[0026] The bending part 905 and the baffle 906 together form an L-shaped plate; a guide ramp 907 is also provided on the bottom side of the baffle 906.

[0027] Here, a guide slope 907 and a cleaning brush 908 are provided on the bottom side plate of the baffle 906. On the one hand, they provide a guiding function for the mist sprayed from the first nozzle 81 or the second nozzle 82. On the other hand, they can also clean the impurities at the nozzle positions of the first nozzle 81 and the second nozzle 82 to ensure the smooth operation of the dust suppression work.

[0028] From the appendix Figure 12 It can be seen that the cleaning brushes 908 are symmetrically arranged on the slope of the guide slope 907, and there are two rows of them.

[0029] From the appendix Figure 11 - Appendix Figure 12 As shown, the baffle 906 in this solution is detachable and is installed through a connecting structure.

[0030] The connection structure includes a docking slot 1001 disposed at one end of the support piece 903 and a docking plug 1002 disposed at one end of the connecting piece 904; the docking plug 1002 is inserted into the docking slot 1001.

[0031] The connection structure also includes a positioning slot 1003 provided on the docking insert 1002 and a screw hole body 1004 provided in the support plate 903 and communicating with the docking slot 1001; a positioning screw 1005 adapted to and engaged with the positioning slot 1003 is provided in the screw hole body 1004.

[0032] To install the baffle 906, insert the mating insert 1002 at the end of the connecting piece 904 into the mating slot 1001 at the end of the support piece 903. Ensure that the positioning slot 1003 on the mating insert 1002 is aligned with the screw hole 1004 in the support piece 903. Then, use the positioning screw 1005 to position the mating insert 1002 by screwing it into the screw hole 1004 until the positioning screw 1005 engages with the positioning slot 1003. This completes the installation of the connecting piece 904, and thus the installation of the baffle 906. The installation is convenient.

[0033] When it is necessary to disassemble and replace the baffle 906 or clean the cleaning brush 908 at its bottom, loosen the positioning screw 1005 until the positioning screw 1005 is released from the positioning slot 1003, and then pull the docking plug 1002 out of the docking slot 1001. The operation is convenient.

[0034] From the appendix Figure 3 - Appendix Figure 10 As shown, in order to further improve the dust suppression effect of the spray and the cleaning effect on the first nozzle 81 and the second nozzle 82, the dust suppression auxiliary mechanism in this solution also includes an auxiliary component for supporting and driving the lightweight support bar 901.

[0035] The auxiliary component includes an inner blade 1101 that is fixedly connected to the inner ring lightweight support bar 901 and an outer blade 1102 that is fixedly connected to the outer ring lightweight support bar 901. The auxiliary component also includes a rotating seat ring 1201 for mounting the inner blade 1101 and the outer blade 1102; the rotating seat ring 1201 is provided in two sets on the inner side of the front end of the fog cannon body 5. The inner blade 1101 is arranged in a ring at equal intervals on the inner side of the rotating seat ring 1201 away from the front end of the fog cannon body 5, and the outer blade 1102 is arranged in a ring at equal intervals on the inner side of the rotating seat ring 1201 close to the front end of the fog cannon body 5.

[0036] The auxiliary components also include a connecting ring 1202 disposed on the outer side of the rotating seat ring 1201, and a limiting ring 1203 disposed on the outer ring surface of the connecting ring 1202; a first auxiliary ball 1204 is also equidistantly disposed on the outer ring surface of the rotating seat ring 1201, and a second auxiliary ball 1205 is equidistantly disposed on the outer ring surface of the limiting ring 1203.

[0037] The auxiliary components also include a receiving cavity 1303 for accommodating the placement of the limiting ring 1203; the receiving cavity 1303 is formed by splicing two sets of loading frame rings 1301, and a fixing foot plate 1302 is fixedly provided on the outside of the loading frame ring 1301. The fixing foot plate 1302 is fixed to the inner wall of the front end of the cannon nozzle 5 by screws.

[0038] In other words, the auxiliary components provide support and allow rotation of the lightweight support strips 901. When the axial flow fan 7 delivers air along the axis of the main body 5 of the mist cannon, the airflow passes through the inner blades 1101 and outer blades 1102 arranged in an equidistant ring. The airflow causes the rotating seat ring 1201 containing both blades to rotate, which in turn causes each lightweight support strip 901 to move in a circular motion. Finally, the flow-expanding curved plate 902 and the baffle plate 906 move in a circular motion. During this process, the flow-expanding curved plate 902 expands the airflow to increase the delivery range of the sprayed mist, thereby increasing the dust suppression range and better adapting to on-site construction needs. In addition, the guide slope 907 set at the bottom of the baffle plate 906 also disperses and guides the sprayed mist when it passes the nozzle, which also plays a positive role in increasing the dust suppression range. The cleaning brush 908 can clean the impurities on each nozzle.

[0039] Among them, from the appendix Figure 6 - Appendix Figure 8 As shown in the diagram, the inner blade 1101 and the outer blade 1102 are arranged with opposite blade tilt directions. That is, when the axial flow air is blown by the axial flow fan 7, the rotation direction of the rotating seat ring 1201 where the inner blade 1101 is located is opposite to the rotation direction of the rotating seat ring 1201 where the outer blade 1102 is located. In other words, when the axial flow air passes by, one rotating seat ring 1201 rotates clockwise and the other rotating seat ring 1201 rotates counterclockwise.

[0040] Furthermore, the inner blade 1101 is higher than the outer blade 1102. Since both blades are provided with lightweight support strips 901, the lightweight support strips 901 in this design are arranged in two sets at equal intervals in a ring, forming an inner ring lightweight support strip 901 and an outer ring lightweight support strip 901; the support piece 903 at the end of the inner ring lightweight support strip 901 is higher than the support piece 903 at the end of the outer ring lightweight support strip 901.

[0041] When the rotating seat ring 1201 near the front muzzle of the main body 5 of the fog cannon rotates, the outer blade 1102 on it will drive the lightweight support strip 901 on it to rotate. In addition, the baffle 906 at the top of the lightweight support strip 901 will pass over the second nozzle 82 during the rotation. That is, the baffle 906 at the end of the outer ring lightweight support strip 901 will disperse and expand the mist sprayed by the second nozzle 82 of the inner ring and clean its nozzle position. The baffle 906 at the end of the inner ring lightweight support strip 901 will disperse and expand the mist sprayed by the first nozzle 81 of the outer ring and clean its nozzle position.

[0042] Then from the appendix Figure 9 - Appendix Figure 10 As can be seen, the limiting ring 1203 is located in the receiving cavity 1303. The first auxiliary ball 1204 and the second auxiliary ball 1205 set in this scheme are intended to improve the smoothness of the rotation of the rotating seat ring 1201 and the limiting ring 1203.

[0043] The specific process is as follows: when the axial flow fan 7 conveys the air body along the axial direction of the fog cannon body 5, the axial flow air body first passes through the inner blade 1101 and then through the outer blade 1102, which respectively drive the rotating seat ring 1201 where the blades are located to rotate. The rotating seat ring 1201 drives the lightweight support strips 901 on its inner blades 1101 to perform circular motion. The circular motion of the lightweight support strips 901 ultimately drives the baffles 906 at their ends to perform circular motion. Among them, the baffles 906 on the outer ring lightweight support strips 901 move around the second nozzle 82 of the inner ring, and the baffles 906 on the inner ring lightweight support strips 901 move around the first nozzle 81 of the outer ring. Specifically, the guide ramp 907 located on the bottom side of the baffle 906 at the end of the outer ring lightweight support bar 901 provides an outward diffusion effect for the mist sprayed by the second nozzle 82 when it passes the position of the second nozzle 82. At the same time, the cleaning brush 908 located on the guide ramp 907 provides a cleaning function for the nozzle of the second nozzle 82. Similarly, the guide ramp 907 located on the bottom side of the baffle 906 at the end of the inner ring lightweight support bar 901 provides an outward diffusion effect for the mist sprayed by the first nozzle 81 when it is at the position of the first nozzle 81. At the same time, the cleaning brush 908 located on the guide ramp 907 provides a cleaning function for the nozzle of the first nozzle 81. When the axial airflow passes through the diffuser plate 902 on the side wall of each lightweight support bar 901, the diffuser plate 902 also has a diffusion effect on the axial airflow; during this process, the diffused airflow will blow towards the mist sprayed from the first nozzle 81 and the second nozzle 82, thereby also providing a spray diffusion effect.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
