Description

Technical Field

[0001] The present invention belongs to the technical field of dust removal equipment, and particularly relates to an intelligent dust reduction device for construction sites. Background Art

[0002] With the growth of the population, people need a large number of housing units to meet their living needs. Construction can build various types of residences, such as apartments, villas, affordable housing, etc., providing people with a safe and comfortable living environment. However, a large amount of dust is generated during construction. Operations such as earth excavation, material handling, and concrete mixing will raise dust. Construction workers are long-term exposed to a high-concentration dust environment and are prone to inhaling a large number of dust particles. These particles will deposit in the respiratory tract and lungs, and long-term accumulation may cause respiratory diseases. Moreover, if this dust is not controlled, it will enter the atmospheric environment, causing air pollution and affecting the air quality of the surrounding area. Therefore, workers usually set up a spraying system at the construction site. The water is sprayed into the air in the form of mist through atomizing nozzles, so that the dust particles combine with the water mist, increase their weight and then settle to the ground, thereby achieving the purpose of dust reduction.

[0003] Existing atomizing nozzles are usually installed at fixed points, and their water spray is distributed in a conical or fan-shaped pattern. The horizontal coverage radius of a single nozzle is relatively small, making it difficult to form a uniform water mist layer over a large area, resulting in an unsatisfactory dust suppression effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an intelligent dust reduction device for construction sites.

[0005] The technical solution adopted to solve the above technical problem is: an intelligent dust reduction device for construction sites, including a dust reduction installation box. A detachable water flow driving mechanism is installed on one side of the dust reduction installation box. A linkage mechanism is arranged below the dust reduction installation box, and a spray adjustable mechanism is arranged below the linkage mechanism. A rapid flow installation plate is fixedly installed in the dust reduction installation box, and a plurality of groups of flow channels are uniformly fixedly connected to the circumference of the lower end of the dust reduction installation box. An installation column is fixedly installed at the lower end of the spray adjustable mechanism. A support frame is fixedly connected to one side of the installation column, and a reinforcing rib is fixedly connected to the support frame. The spray adjustable mechanism can blow out air to disperse the accumulated water mist, keeping the working area relatively dry and reducing problems such as slippery ground and equipment corrosion caused by water accumulation.

[0006] Through the above technical solution, the setting of the rapids installation plate can concentrate the water flow into the effective action area of the installation fan blades, making the impact force of the water flow on the installation fan blades more concentrated. The setting of the rapids installation plate divides the space inside the dust reduction installation box into a space with installation fan blades at the upper end and a space without installation fan blades at the lower end. When the water flow enters the inside of the dust reduction installation box, due to the setting of the rapids installation plate, the tangential water flow input by the liquid inlet pipe can be further converged to the effective action area of the installation fan blades (i.e., the upper space of the blade water-facing surface). The water flow enters the dust reduction installation box in a tangential shape, and naturally, a high-speed and concentrated fluid beam can be formed, directly impacting the blades of the installation fan blades, thereby maximizing the conversion efficiency of the kinetic energy of the water flow into the rotational kinetic energy of the installation shaft. After that, the water flow will naturally flow into the lower end of the dust reduction installation box through the gap between the rapids installation plate and the installation shaft, enhancing the rotational power of the installation shaft; and the reinforcing ribs can increase the overall strength and stiffness of the support frame, enabling it to withstand greater external forces and loads. By dispersing and transmitting the acting forces, it can prevent the support frame from deforming, bending, or even breaking when subjected to large pressures, tensile forces, or torsional forces, ensuring the stability and safety of the structure.

[0007] Further, the water flow driving mechanism includes an installation shaft rotatably connected to the dust reduction installation box. A plurality of groups of installation fan blades are evenly fixed on the installation shaft in a circumferential manner. One side of the dust reduction installation box is fixedly installed with a liquid inlet pipe. One end of the liquid inlet pipe away from the dust reduction installation box is fixedly connected with a first connection seat. One side of the first connection seat is fixedly installed with a second connection seat. An outlet pipe is fixedly connected to the second connection seat. The outlet pipe is connected to the water tank outlet pipe. The first connection seat and the second connection seat are fixedly connected by a plurality of groups of fixing bolts.

[0008] Through the above technical solution, the water flow driving mechanism uses the energy of the water flow to drive the installation shaft to rotate, converting the kinetic energy of the water flow into the mechanical energy of the installation shaft, and then driving the connection box body and a plurality of atomizing nozzles to rotate, effectively utilizing the water flow resources without an additional power source.

[0009] Further, the liquid inlet pipe is in mutual communication with the inside of the dust reduction installation box, and the liquid inlet channel of the liquid inlet pipe is arranged in a tangential structure with the dust reduction installation box.

[0010] Through the above technical solution, the water flow input by the liquid inlet pipe can enter the dust reduction installation box through the liquid inlet, and since the liquid channel is in a tangential structure with the dust reduction installation box, the water flow entering the dust reduction installation box can drive the linkage mechanism to rotate.

[0011] Further, an installation base is arranged at the lower end of the installation column. The installation base is fixedly connected to the installation column, and a counterweight is installed on the installation base.

[0012] Through the above technical solution, the counterweight increases the weight of the mounting base, reducing the center of gravity of the entire device. The lower the center of gravity, the more stable the object. When subjected to external forces, the device is less likely to tip over or shake, thereby improving the overall stability of the device during use.

[0013] Furthermore, the linkage mechanism includes a connecting shaft fixedly connected to the lower end of the mounting shaft. A first mounting bearing is sleeved between the connecting shaft and the dust reduction mounting box. The lower end of the connecting shaft is fixedly connected to a connecting frame. An installation ring is fixedly connected to the outside of the connecting frame. The installation ring is fixedly connected to the connecting box body. A plurality of groups of installation holes are evenly formed in the lower end of the connecting box body. A plurality of groups of installation pipes are evenly and fixedly installed on the lower surface of the connecting box body. The lower end of the installation pipe is fixedly installed with a spray nozzle, and an independent solenoid valve is installed on each spray nozzle. The dust reduction mounting box communicates with the connecting box body, the installation holes, and the installation pipes. A rotating groove is formed in the installation ring, and a rotating seat is rotatably connected in the rotating groove.

[0014] Through the above technical solution, the rotation of the mounting shaft drives the rotation of the connecting shaft. The connecting shaft can transmit power to the connecting box body through the action of the connecting frame, so that the spray nozzles on the connecting box body can rotate following the rotation of the connecting shaft, and the water mist can be evenly sprayed in a ring shape.

[0015] Furthermore, the spray adjustable mechanism includes an air inlet base rotatably connected to the linkage mechanism. The lower end of the air inlet base is fixedly connected to an air inlet box. A plurality of groups of air inlet holes are circumferentially formed in the air inlet box. The upper end of the air inlet base is fixedly connected to a fixed shaft. A second mounting bearing is sleeved between the outer side of the fixed shaft and the linkage mechanism. An electric fan is installed in the air inlet box. The lower end of the air inlet box is fixedly connected to a motor box. A driving motor is fixedly installed in the motor box. The output end of the driving motor is fixedly connected to a driving shaft. A driving plate is fixedly installed on the driving shaft. The driving plate is rotatably connected to the air inlet box.

[0016] Through the above technical solution, the output end of the driving motor drives the driving plate to rotate through the driving shaft, so that the positions of the first communication holes and the second communication holes coincide with each other. And the electric fan will suck a large amount of air through a plurality of groups of air inlet holes, and then the air flow will enter the air inlet box. The high-speed air flow will enter the jet pipe through the first communication hole and the second communication hole, and then be ejected through a plurality of jet pipes.

[0017] Furthermore, a plurality of groups of first communication holes are evenly formed in the driving plate. A plurality of groups of second communication holes are evenly formed in the lower end of the air inlet box. By rotating the driving plate at different angles, the first communication holes and the second communication holes can be made to communicate with each other.

[0018] Through the above technical solution, when the first communication hole and the second communication hole are connected to each other, the air jet pipe for jetting air can jet out air to form an air flow, which can push the water mist generated by the atomizing nozzle to spread more evenly around, expand the dust suppression coverage range, make the dust suppression area more comprehensive, and the air flow and the water mist interact with each other. On the one hand, the water mist particles and the dust particles can contact and collide more fully, increasing the probability of the dust being adsorbed by the water mist; on the other hand, the air flow drives the mixture of the water mist and the dust to settle quickly downward, accelerating the dust suppression speed and improving the dust suppression efficiency.

[0019] Further, a plurality of groups of air jet pipes are uniformly arranged at the lower end of the air inlet box. The air inlet box is fixedly connected with the plurality of groups of air jet pipes, and the plurality of groups of air jet pipes communicate with the air inlet box. The bending angles of the air jet pipes are different from each other.

[0020] Through the above technical solution, the air flows ejected from different jet angles of the air jet pipes interact with each other to form a variable air flow field around the device. This air flow field can change the movement trajectory of the dust particles in the air, increase the collision chance between the dust and the water mist, and improve the probability of the dust being adsorbed by the water mist.

[0021] The beneficial effects of the present invention are as follows: (1) By designing a supporting water flow driving mechanism and a linkage mechanism, the water flow driving mechanism uses the energy of the water flow to drive the installation shaft to rotate, converts the kinetic energy of the water flow into the mechanical energy of the installation shaft, and then drives the connection box body and a plurality of atomizing nozzles to rotate, effectively utilizing the water flow resources, without an additional power source, reducing the energy consumption and operation cost; (2) By designing a spray adjustable mechanism, the air jet pipe for jetting air can jet out air to form an air flow, which can push the water mist generated by the atomizing nozzle to spread more evenly around, expand the dust suppression coverage range, make the dust suppression area more comprehensive, and the air flow and the water mist interact with each other. On the one hand, the water mist particles and the dust particles can contact and collide more fully, increasing the probability of the dust being adsorbed by the water mist; on the other hand, the air flow drives the mixture of the water mist and the dust to settle quickly downward, accelerating the dust suppression speed and improving the dust suppression efficiency; at the same time, the water mist generated by the atomizing nozzle will accumulate in some areas to form ponding, and the spray adjustable mechanism can jet out air to disperse the accumulated water mist, keeping the working area relatively dry and reducing the problems of slippery ground and equipment corrosion caused by ponding; (3) By designing air jet pipes with different angles, the air flows ejected from different jet angles of the air jet pipes interact with each other to form a variable air flow field around the device. This air flow field can change the movement trajectory of the dust particles in the air, increase the collision chance between the dust and the water mist, and improve the probability of the dust being adsorbed by the water mist.

Detailed implementation manners

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] As Figures 1 - 5As shown in the figure, an intelligent dust reduction device for a construction site in this embodiment includes a dust reduction installation box 1. A detachable water flow driving mechanism 2 is installed on one side of the dust reduction installation box 1. A linkage mechanism 3 is arranged below the dust reduction installation box 1, and a spray adjustable mechanism 4 is arranged below the linkage mechanism 3. A rapid flow installation plate 11 is fixedly installed in the dust reduction installation box 1, and a plurality of flow channels 12 are fixedly connected to the lower end circumference of the dust reduction installation box 1 in a uniform manner. The lower end of the spray adjustable mechanism 4 is fixedly installed with an installation column 52. One side of the installation column 52 is fixedly connected with a support frame 5. A reinforcing rib 51 is fixedly connected to the support frame 5. The setting of the rapid flow installation plate 11 can concentrate the water flow into the effective action area of the installation fan blade 26, make the impact force of the water flow on the installation fan blade 26 more concentrated, and enhance the rotational power of the installation shaft 25. Moreover, the reinforcing rib 51 can increase the overall strength and stiffness of the support frame 5, enabling it to withstand greater external forces and loads. By dispersing and transmitting the acting forces, it can prevent the support frame 5 from deforming, bending or even breaking when subjected to large pressure, tension or torsion, ensuring the stability and safety of the structure. Further, the spray adjustable mechanism can blow out air to disperse the gathered water mist, keep the working area relatively dry, and reduce problems such as slippery ground and equipment corrosion caused by water accumulation. The lower end of the installation column 52 is provided with an installation base 54. The installation base 54 is fixedly connected to the installation column 52. A counterweight 53 is installed on the installation base 54. The counterweight 53 increases the weight of the installation base 54, lowering the center of gravity of the entire device. The lower the center of gravity, the more stable the object. When subjected to external forces, the device is less likely to tip over or shake, thereby improving the overall stability of the device during use.

[0026] As Figures 1 - 4 shown in the figure, the water flow driving mechanism 2 includes an installation shaft 25 rotatably connected to the dust reduction installation box 1. A plurality of installation fan blades 26 are fixedly installed on the installation shaft 25 in a uniform manner around the circumference. One side of the dust reduction installation box 1 is fixedly installed with a liquid inlet pipe 20. One end of the liquid inlet pipe 20 away from the dust reduction installation box 1 is fixedly connected with a first connection seat 21. A second connection seat 22 is fixedly installed on one side of the first connection seat 21. An outlet pipe 24 is fixedly connected to the second connection seat 22. The outlet pipe 24 is connected to the water tank outlet pipe. The first connection seat 21 and the second connection seat 22 are fixedly connected by a plurality of fixing bolts 23. The water flow driving mechanism 2 uses the energy of the water flow to drive the installation shaft 25 to rotate, converting the kinetic energy of the water flow into the mechanical energy of the installation shaft 25, and then driving the connection box body 33 and a plurality of atomizing nozzles 36 to rotate, effectively utilizing the water flow resources without an additional power source. The liquid inlet pipe 20 is mutually communicated with the inside of the dust reduction installation box 1, and the liquid inlet channel of the liquid inlet pipe 20 is arranged in a tangential structure with the dust reduction installation box 1, so that the water flow input by the liquid inlet pipe 20 can enter the dust reduction installation box 1 through the liquid inlet. And because the liquid channel is arranged in a tangential structure with the dust reduction installation box 1, the water flow entering the dust reduction installation box 1 can drive the linkage mechanism 3 to rotate.

[0027] As Figures 1 - 7 shown, the linkage mechanism 3 includes a connecting shaft 30 fixedly connected to the lower end of the mounting shaft 25. A first mounting bearing 39 is sleeved between the connecting shaft 30 and the dust reduction mounting box 1. A connecting frame 31 is fixedly connected to the lower end of the connecting shaft 30. An installation ring 32 is fixedly connected to the outside of the connecting frame 31. The installation ring 32 is fixedly connected to the connecting box body 33. A plurality of groups of installation holes 34 are evenly formed in the lower end of the connecting box body 33. A plurality of groups of installation pipes 35 are evenly and fixedly installed on the lower surface of the connecting box body 33. The lower end of the installation pipe 35 is fixedly installed with an atomizing nozzle 36, and an independent electromagnetic valve is installed on each atomizing nozzle 36. The dust reduction mounting box 1 communicates with the connecting box body 33, the installation holes 34, and the installation pipes 35. A rotating groove 37 is formed in the installation ring 32, and a rotating seat 38 is rotatably connected in the rotating groove 37. When the mounting shaft 25 rotates, it drives the connecting shaft 30 to rotate. The connecting shaft 30 can transmit power to the connecting box body 33 through the action of the connecting frame 31, so that the atomizing nozzles 36 on the connecting box body 33 can rotate following the rotation of the connecting shaft 30, and the water mist can be sprayed evenly in a ring shape.

[0028] As Figures 1 - 9As shown, the spray adjustable mechanism 4 includes an air inlet base 40 rotatably connected to the linkage mechanism 3. The lower end of the air inlet base 40 is fixedly connected with an air inlet box 41. A plurality of groups of air inlet holes 42 are circumferentially formed on the air inlet box 41. The upper end of the air inlet base 40 is fixedly connected with a fixed shaft 43. A second mounting bearing 44 is sleeved between the outer side of the fixed shaft 43 and the linkage mechanism 3. An electric fan 45 is installed in the air inlet box 41. The lower end of the air inlet box 41 is fixedly connected with a motor box 48. A driving motor 49 is fixedly installed in the motor box 48. The output end of the driving motor 49 is fixedly connected with a driving shaft 410. A driving plate 46 is fixedly installed on the driving shaft 410. The driving plate 46 is rotatably connected to the air inlet box 41. The output end of the driving motor 49 drives the driving shaft 410 to rotate. The driving shaft 410 transmits power to the driving plate 46, thereby driving the driving plate 46 to rotate. When the first communication hole 47 on the driving plate 46 rotates to a position where it coincides with the second communication hole 411, at this time, the air inlet box 41 and the jet pipe 412 are interconnected through the first communication hole 47 and the second communication hole 411. And the electric fan 45 will inhale a large amount of air through a plurality of groups of air inlet holes 42. Then the air flow will enter the air inlet box 41. The high-speed air flow will pass through the first communication hole 47 and the second communication hole 411 and enter the jet pipe 412, and then be ejected through a plurality of jet pipes 412; A plurality of groups of first communication holes 47 are evenly formed on the driving plate 46. A plurality of groups of second communication holes 411 are evenly formed at the lower end of the air inlet box 41. By rotating and adjusting the driving plate 46 at different angles, the first communication hole 47 and the second communication hole 411 can be made to communicate with each other. When the first communication hole 47 and the second communication hole 411 communicate with each other, the air ejected from the jet pipe 412 of the spray can form an air flow, which can push the water mist generated by the atomizing nozzle 36 to spread more evenly around, expand the dust suppression coverage range, make the dust suppression area more comprehensive. The air flow and the water mist interact with each other. On the one hand, it makes the water mist particles and the dust particles contact and collide more fully, increasing the probability of the dust being adsorbed by the water mist; On the other hand, the air flow drives the mixture of the water mist and the dust to settle quickly downward, accelerating the dust suppression speed and improving the dust suppression efficiency.

[0029] As Figures 1 - 5 As shown, a plurality of groups of jet pipes 412 are evenly arranged at the lower end of the air inlet box 41. The air inlet box 41 is fixedly connected with a plurality of groups of jet pipes 412. A plurality of groups of jet pipes 412 are interconnected with the air inlet box 41. The bending angles of the plurality of groups of jet pipes 412 are different. The air flows ejected from different jet angles of the jet pipe 412 interact with each other to form a variable air flow field around the device. This air flow field can change the movement trajectory of the dust particles in the air, increase the collision chance between the dust and the water mist, and improve the probability of the dust being adsorbed by the water mist.

[0030] The working principle of this embodiment is as follows. Connect the liquid outlet pipe 24 to the water tank outlet pipe. The water pump pumps the water flow in the water tank into the dust suppression installation box 1 through the liquid inlet pipe 20. After the water flow enters the dust suppression installation box 1 through the liquid inlet pipe 20, the water flow will push multiple installation fan blades 26 to rotate along the tangential direction, and then can drive the installation shaft 25 and the linkage mechanism 3 to rotate. The setting of the rapid flow installation plate 11 can concentrate the water flow into the effective action area of the installation fan blades 26, make the impact force of the water flow on the installation fan blades 26 more concentrated, and enhance the rotational power of the installation shaft 25. The water flow passes through the gap between the rapid flow installation plate 11 and the installation shaft 25 and then enters the connection box body 33 through the flow channel 12, enters the installation pipe 35 through the installation hole 34, and is atomized and sprayed out by the atomizing nozzle 36; At the same time, the rotation of the installation shaft 25 drives the rotation of the connecting shaft 30. The connecting shaft 30 can transmit the power to the connection box body 33 through the action of the connecting frame 31, so that the atomizing nozzles 36 on the connection box body 33 can rotate following the rotation of the connecting shaft 30, and the water mist can be sprayed evenly in a ring shape; When the water mist is sprayed evenly, start the driving motor 49. The output end of the driving motor 49 drives the driving shaft 410 to rotate. The driving shaft 410 transmits the power to the driving plate 46, and then drives the driving plate 46 to rotate. When the driving plate 46 rotates, it can drive the first communication hole 47 on the driving plate 46 to rotate. When the first communication hole 47 rotates to coincide with the position of the second communication hole 411, at this time, the air inlet box 41 and the jet pipe 412 are interconnected through the first communication hole 47 and the second communication hole 411. During actual work, after the electric fan 45 is powered on, the electric fan 45 will inhale a large amount of air through multiple air inlet holes 42, and then the air flow will enter the air inlet box 41. The high-speed air flow will enter the jet pipe 412 through the first communication hole 47 and the second communication hole 411, and then be sprayed out through multiple jet pipes 412, so as to achieve dust suppression in a larger range.

[0031] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
