Description

Technical Field

[0001] This invention relates to the technical field of pollution control and treatment in building construction, specifically to an environmentally friendly dust reduction device for green building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various buildings. During construction, there will be a lot of dust on the construction site. A lot of dust can affect the urban air environment. In order to prevent the dust from spreading and affecting the surrounding workers, dust suppression equipment is usually set up on the construction site. The water mist sprayed by the dust suppression equipment is used to suppress the spread of dust, thereby controlling and treating the air pollution near the construction site.

[0003] Most existing dust suppression spray nozzles are fixed or can only swing in one direction, resulting in spray dead zones and static blind spots. The sprayed water mist has a limited range and is prone to drift and short-distance settling, making the dust suppression range relatively fixed and limited. In addition, during use, the nozzles are prone to clogging due to cold weather or external dust settling. Existing dust suppression equipment does not have a self-cleaning function, and when the nozzles are clogged, the machine needs to be stopped for manual inspection and maintenance, making it relatively inconvenient to use. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an environmentally friendly dust suppression device for green building construction.

Several spray holes are opened on the water spray pipes on the same side as the air nozzles. A water inlet hose is connected to the water distribution cylinder.

[0011] As a preferred embodiment of the present invention, the diameter of the pulley located on the water spray pipe is larger than the diameter of the pulley located on the drive shaft.

[0012] As a preferred embodiment of the present invention, the self-cleaning anti-clogging component includes a movable ring that slides within the water distribution cylinder, a toothed plate fixedly mounted on the movable ring, a rotating shaft rotatably mounted on the water distribution cylinder, a gear meshing with the toothed plate fixedly mounted at one end of the rotating shaft, and an elliptical disc fixedly mounted at the other end of the rotating shaft extending outside the water distribution cylinder. A cleaning component is slidably mounted on each of the spray pipes, an arc-shaped plate is fixedly mounted on the cleaning component, and a drive plate is fixedly mounted on the arc-shaped plate. The drive plate works in conjunction with the elliptical disc.

[0013] As a preferred embodiment of the present invention, the cleaning component includes a plurality of cleaning rings that slide against the water spray pipe, and a common cleaning plate is fixedly installed between the plurality of cleaning rings located on the same water spray pipe.

[0014] As a preferred embodiment of the present invention, a first spring is fixedly installed between each of the cleaning plates and the water distribution cylinder.

[0015] As a preferred embodiment of the present invention, a plurality of telescopic rods are fixedly installed between the movable ring and the inner wall of the water distribution cylinder, and a second spring is sleeved on the outer side of each telescopic rod, and the two ends of the second spring are fixedly connected to the movable ring and the inner wall of the water distribution cylinder, respectively.

[0016] As a preferred embodiment of the present invention, the water spray pipe and the air supply pipe are arranged coaxially.

[0017] As a preferred embodiment of the present invention, a plurality of nozzles located around the same nozzle are evenly distributed in a circumferential array.

[0018] As a preferred embodiment of the present invention, a drive motor is fixedly installed inside the control box, and the output end of the drive motor is fixedly connected to the rotating disk for driving the rotating disk to rotate.

[0019] The beneficial effects of this invention are:

[0020] 1. This environmentally friendly dust suppression device for green building construction is equipped with spray nozzles, air nozzles, an inner cylinder, a water distribution cylinder, an air supply pipe, a water spray pipe, an inlet hose, and a water spray hose. An external water pump delivers the water required for dust suppression through the inlet hose to the water distribution cylinder, then through the water distribution cylinder to the water spray pipe, and finally through the spray nozzles on the water spray pipe for dust suppression. An external air pump introduces gas into the inner cylinder through the air supply hose, then through the inner cylinder to the air supply pipe, and finally through the air nozzles. The ejected gas forms an air curtain and mixes with the water mist sprayed from the nozzles. Under the protection and guidance of the air curtain, the water mist has a longer range and a more uniform distribution, effectively suppressing water mist dispersion and short-distance settling. This allows it to effectively reach farther dust points even in complex airflow environments at construction sites, greatly improving the effective dust suppression range and the dust suppression effect, while reducing the amount of water required for spraying, thus saving energy and protecting the environment.

[0021] 2. This type of environmentally friendly dust suppression device for green building construction, through the installation of a spray adjustment component, uses an external air pump to input gas into the inner cylinder, while another portion of the gas drives the impeller to rotate and is discharged through the vent. The rotation of the impeller drives the worm gear and the drive shaft to rotate, and the rotation of the drive shaft drives the water spray pipe to rotate through the pulley and synchronous belt. The rotation of the water spray pipe drives all nozzles and spray holes to rotate synchronously and regularly, adjusting the spray angle of the spray holes. This allows the spray holes to perform 360-degree spraying operation in a cyclical manner during use, greatly expanding the spray atomization coverage area, eliminating spray dead angles and static blind spots, forming a three-dimensional, scanning spray dust suppression network, and greatly improving the spray dust suppression effect.

[0022] 3. This environmentally friendly dust suppression device for green building construction utilizes pulleys, synchronous belts, worm gears, and worm shafts. The rotating shaft is driven by the reduction gears of the worm gears and worm shafts, which in turn drive the water spray pipes to rotate slowly. This ensures smooth and continuous rotation of the spray nozzles, guaranteeing the stability and uniformity of the spray water curtain and preventing excessively rapid rotation from causing the mist field to break up and resulting in uneven coverage. Simultaneously, it utilizes a portion of the airflow originally intended for forming an air curtain as a driving source, achieving "dual functionality." This eliminates the need for additional motors and drivers for the spray adjustment system, simplifying the electrical control system and significantly reducing manufacturing costs and overall energy consumption. Furthermore, the worm gear configuration allows the entire water spray pipe to be locked in its current position when airflow is interrupted, eliminating the need for additional brakes or locking devices, thus saving energy and improving system safety and reliability.

[0023] 4. This environmentally friendly dust suppression device for green building construction, by incorporating a self-cleaning anti-clogging component, causes the water level in the water distribution cylinder to rise when the spray nozzles become clogged. This rise pushes the moving ring upwards, which in turn drives the gears, rotating shaft, and elliptical disc to rotate. During the rotation of the elliptical disc, it repeatedly squeezes the drive plates on both sides, thereby driving the cleaning plate and cleaning ring to reciprocate and clean the spray nozzles and water pipes to prevent clogging. Simultaneously, because the water pipes rotate slowly and continuously during use, the cleaning effect of the cleaning plate and cleaning ring is further enhanced. Therefore, when a spray nozzle becomes clogged, the rising water level in the distribution cylinder automatically drives the disc to rotate, which in turn drives the cleaning plate and cleaning ring to perform a self-cleaning anti-clogging operation on the spray nozzle. This not only effectively prevents spray nozzle clogging and ensures a long-term stable spraying effect, but also greatly reduces the labor intensity of manual inspection and cleaning.

[0024] 5. This environmentally friendly dust suppression device for green building construction incorporates a second spring. Under its own elasticity, the second spring can absorb minor fluctuations in the liquid level within the water distribution cylinder, raising the threshold for liquid level changes required for self-cleaning and anti-clogging operation. This prevents the self-cleaning and anti-clogging operation from being triggered by minor fluctuations in the liquid level within the water distribution cylinder. Furthermore, when the moving ring moves upward, it compresses the second spring. After the spray nozzles spray smoothly, the second spring, under its own elasticity, can quickly drive the moving ring to reset.

[0025] 6. This environmentally friendly dust suppression device for green building construction, by setting up a drive motor and a rotating disc, can drive the rotating disc to rotate according to the spraying needs, thereby driving the water spray pipe to rotate, which can further expand the dust suppression range of the device.

[0036] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0037] Example: Figures 1 to 8As shown, the present invention discloses an environmentally friendly dust suppression device for green building construction, which further includes: a control box 2: the control box 2 is fixedly installed on a movable base 1, a rotating disk 3 is rotatably installed on it, an electric push rod 4 is fixedly installed on the rotating disk 3, and an installation plate 5 is fixedly installed at the output end of the electric push rod 4; an inner cylinder 6: the inner cylinder 6 is fixedly installed on the installation plate 5, an air inlet hose 7 is connected to the inner cylinder 6, and a spray adjustment component 8 is provided inside the inner cylinder 6; and a water distribution cylinder 10: the water distribution cylinder 10 is fixedly installed on the outside of the inner cylinder 6, with water distribution cylinder 10 on both sides. Each water pipe 11 is rotatably installed, and an air supply pipe 12 is fixedly installed inside each water pipe 11. The ends of two air supply pipes 12 that are close to each other extend into the water distribution cylinder 10 and are rotatably connected to the inner cylinder 6. Several air nozzles 13 are connected to the air supply pipe 12, and the several air nozzles 13 extend outside the water pipe 11. Several spray holes 14 are opened on the water pipe 11 on the same side as the air nozzles 13. A water inlet hose 15 is connected to the water distribution cylinder 10. A self-cleaning anti-clogging component 9 is provided inside the water distribution cylinder 10 to prevent the spray holes 14 from being blocked.

[0038] In use, the device is moved to the area where dust suppression is required via the movable base 1. Then, the water inlet hose 15 and the air inlet hose 7 are connected to the external water pump and air pump respectively. The external water pump delivers the water required for dust suppression spraying through the water inlet hose 15 to the water distribution cylinder 10, and then through the water distribution cylinder 10 to the water spray pipe 11. The water is then sprayed out through the nozzles 14 on the water spray pipe 11 to perform the dust suppression spraying operation. The external air pump inputs gas into the inner cylinder 6 through the air inlet hose 7, and then through the inner cylinder 6 to the air supply pipe 12. The gas is then sprayed out through the air nozzles 13. The sprayed gas forms an air curtain and mixes with the water mist sprayed from the nozzles 14. Under the wrapping and guidance of the air curtain, the water mist has a longer range and a more uniform distribution, effectively suppressing water mist dispersion and short-distance settling. This allows it to effectively reach farther dust points even in construction sites with complex airflow environments, greatly improving the effective dust suppression range and spraying dust suppression effect, while reducing the amount of water required for spraying, thus saving energy and protecting the environment.

[0039] The spray adjustment assembly 8 includes a drive shaft 81 rotatably mounted on the inner cylinder 6. The top of the inner cylinder 6 has several vent holes 82, and a rotating shaft 83 is also rotatably mounted on the top of the inner cylinder 6. An impeller 84 is fixedly mounted on the rotating shaft 83. A worm gear 85 is fixedly mounted in the middle of the drive shaft 81. A worm 86 that meshes with the worm gear 85 is fixedly mounted on the rotating shaft 83. Pulleys 87 are fixedly mounted on both the water spray pipe 11 and the drive shaft 81 on the same side. A synchronous belt 88 is sleeved between the two pulleys 87 and the two pulleys are connected by transmission through the synchronous belt 88.

[0040] An external air pump inputs gas into the inner cylinder 6. Part of the gas flows into the air supply pipe 12, while the other part drives the impeller 84 to rotate and is discharged through the vent 82. The rotation of the impeller 84 drives the worm wheel 85 and the drive shaft 81 to rotate via the worm gear 86. The rotation of the drive shaft 81 drives the water spray pipe 11 to rotate via the pulley 87 and the synchronous belt 88. The rotation of the water spray pipe 11 drives all the nozzles and spray holes 14 to rotate synchronously and regularly, adjusting the spray angle of the spray holes 14. This allows the spray holes 14 to perform 360-degree spraying operations in a cyclical manner during use, greatly expanding the spray atomization coverage area, eliminating spray dead angles and static blind spots, forming a three-dimensional, scanning spray dust suppression network, and greatly improving the spray dust suppression effect.

[0041] The diameter of the pulley 87 on the water spray pipe 11 is larger than that of the pulley 87 on the drive shaft 81, and the worm gear 85 and worm 86 are self-locking, so that the rotational speed of the water spray pipe 11 is less than the rotational speed of the drive shaft 81. That is, when the impeller 84 drives the rotating shaft 83 to rotate, the rotating shaft 83 drives the drive shaft 81 to rotate through the reduction transmission of the worm gear 85 and worm 86. The drive shaft 81 drives the water spray pipe 11 to rotate slowly under the reduction transmission of the pulley 87 and the synchronous belt 88, so that the rotation of the spray nozzle 14 is smooth and continuous, ensuring the stability of the spray water curtain. The system ensures stability and uniformity, preventing excessively rapid rotation from causing the mist field to break up and resulting in uneven coverage. Simultaneously, it utilizes a portion of the airflow originally intended for forming an air curtain as a driving source, achieving "dual functionality." This eliminates the need for additional motors and drivers in the spray adjustment system, simplifying the electrical control system and significantly reducing manufacturing costs and overall energy consumption. Furthermore, the worm gear 85 and worm 86 allow the entire spray pipe 11 to be locked in its current position when airflow is interrupted, eliminating the need for additional brakes or locking devices. This saves energy and improves the system's safety and reliability.

[0042] The self-cleaning anti-clogging component 9 includes a movable ring 91 that slides within the water distribution cylinder 10. A toothed plate 92 is fixedly mounted on the movable ring 91. A rotating shaft 93 is rotatably mounted on the water distribution cylinder 10. A gear 94 that meshes with the toothed plate 92 is fixedly mounted at one end of the rotating shaft 93. The other end of the rotating shaft 93 extends outside the water distribution cylinder 10 and is fixedly mounted on an elliptical disc 95. A cleaning component 96 is slidably mounted on each water spray pipe 11. An arc-shaped plate 97 is fixedly mounted on the cleaning component 96, and a drive plate 98 is fixedly mounted on the arc-shaped plate 97. The drive plate 98 works in conjunction with the elliptical disc 95. The cleaning component 96 includes several cleaning rings 961 that slide within the water spray pipe 11, and the same cleaning plate 962 is fixedly mounted between several cleaning rings 961 located on the same water spray pipe 11.

[0043] When the nozzle 14 becomes clogged, or in a cold environment, the nozzle 14 freezes and becomes clogged, the water in the water distribution cylinder 10 cannot be sprayed out of the nozzle 14 in time. This causes the water level in the water distribution cylinder 10 to rise, pushing the moving ring 91 upward. The upward movement of the moving ring 91 drives the toothed plate 92 to move upward as well, which in turn drives the gear 94, the rotating shaft 93, and the elliptical disk 95 to rotate. During the rotation of the elliptical disk 95, it reciprocates to squeeze the drive plates 98 on both sides. The pressure on the drive plates 98 drives the cleaning plate 962 and the cleaning ring 961 to reciprocate, cleaning the nozzle 14 and the water spray pipe 11 to prevent clogging. At the same time, since the water spray pipe 11 will continue to rotate slowly during use, it can further improve the cleaning effect of the cleaning plate 962 and the cleaning ring 961. When the cleaning ring 961 cleans the nozzle 14, the air nozzle 13 will also be cleaned. The cleaning ring 961 blocks the flow of gas from the air supply pipe 12, reducing the flow of gas from the impeller 84 and increasing the speed of the impeller 84. This increases the speed of the water spray pipe 11, which in turn accelerates the cleaning and anti-clogging operation of the cleaning ring 961 and the cleaning plate 962 on the spray hole 14. After the spray hole 14 is clear and the normal spraying operation is completed, the water level in the water distribution cylinder 10 stops rising and returns to its original position. This causes the elliptical disk 95 and the drive plate 98 to reset. Thus, when the spray hole 14 is blocked, the rise in the liquid level in the water distribution cylinder 10 automatically drives the disk to rotate, which in turn drives the cleaning plate 962 and the cleaning ring 961 to perform self-cleaning and anti-clogging operation on the spray hole 14. This not only effectively prevents the spray hole 14 from clogging and ensures a long-term stable spraying effect, but also greatly reduces the labor intensity of manual inspection and cleaning.

[0044] Each cleaning plate 962 is fixedly installed with a first spring 99 between it and the water distribution cylinder 10. By setting the first spring 99, the drive plate 98 can be closely attached to the elliptical disk 95, ensuring that the elliptical disk 95 can stably drive the drive plate 98 to move, while facilitating the quick reset of the cleaning ring 961 and the cleaning plate 962.

[0045] Several telescopic rods are fixedly installed between the moving ring 91 and the inner wall of the water distribution cylinder 10. Each telescopic rod is fitted with a second spring 910 on its outer side. The two ends of the second spring 910 are fixedly connected to the moving ring 91 and the inner wall of the water distribution cylinder 10, respectively. By setting the second spring 910, the second spring 910 can absorb the small fluctuations of the liquid surface in the water distribution cylinder 10 under its own elastic force, thereby increasing the threshold of liquid level change required for self-cleaning and anti-clogging operation and preventing the activation of self-cleaning and anti-clogging operation due to the small fluctuations of the liquid surface in the water distribution cylinder 10. In addition, when the moving ring 91 moves upward, it will compress the second spring 910. After the spray is successfully applied through the spray hole 14, the second spring 910 can quickly drive the moving ring 91 to reset under its own elastic force.

[0046] The water spray pipe 11 and the air supply pipe 12 are coaxially arranged, and the water spray pipe 11 is sealed to the water distribution cylinder 10, and the air supply pipe 12 is also sealed to the inner cylinder 6 to ensure the airtightness of the device.

[0047] The multiple spray holes 14 located around the same jet nozzle 13 are evenly distributed in a circumferential array, which can improve the spraying effect and ensure the uniformity of the spraying operation. A drive motor 16 is fixedly installed inside the control box 2. The output end of the drive motor 16 is fixedly connected to the rotating disk 3 to drive the rotating disk 3 to rotate. During use, the drive motor 16 can drive the rotating disk 3 to rotate according to the spraying needs, thereby driving the water spray pipe 11 to rotate. This can further expand the spraying dust suppression range of the device. Combined with the rotation of the water spray pipe 11, it achieves 360-degree horizontal coverage and vertical rotating spraying. Compared with the fixed-angle or simply rotating nozzles in the prior art, this eliminates spraying dead angles and static blind spots, forming a three-dimensional, scanning spraying dust suppression network, greatly improving the capture efficiency of suspended dust.

[0048] During operation, the device is moved to the area where dust suppression is required via the movable base 1. Then, the water spray pipe 11 is adjusted to the appropriate spraying height via the electric push rod 4. The water inlet hose 15 and the air inlet hose 7 are connected to the external water pump and air pump respectively. The external water pump delivers the water required for dust suppression through the water inlet hose 15 to the water distribution cylinder 10, and then through the water distribution cylinder 10 to the water spray pipe 11. The water is then sprayed out through the spray holes 14 on the water spray pipe 11 to perform dust suppression. The external air pump inputs gas into the inner cylinder 6 through the air inlet hose 7. A portion of the gas is delivered to the air supply pipe 12 and then sprayed out through the air nozzle 13. The sprayed gas forms an air curtain and mixes with the water mist sprayed from the spray holes 14. Under the wrapping and guidance of the air curtain, the water mist has a longer range and a more uniform distribution, effectively suppressing water mist dispersion and short-distance settling. This allows it to effectively reach farther dust points even in construction sites with complex airflow environments, greatly improving the effective dust suppression range and the dust suppression effect.

[0049] Another portion of the gas drives the impeller 84 to rotate and is discharged through the vent 82. The rotation of the impeller 84 drives the worm wheel 85 and the drive shaft 81 to rotate through the worm gear 86. The rotation of the drive shaft 81 drives the water spray pipe 11 to rotate through the pulley 87 and the synchronous belt 88. The rotation of the water spray pipe 11 drives all the nozzles and spray holes 14 to rotate synchronously and regularly, adjusting the spray angle of the spray holes 14 so that the spray holes 14 can perform 360-degree spraying operation in a cycle during use. At the same time, according to the spraying needs, the drive motor 16 drives the rotating disk 3 to rotate, which in turn drives the water spray pipe 11 to rotate, which can further expand the spray dust suppression range of the device. Combined with the rotation of the water spray pipe 11, it realizes 360-degree coverage in the horizontal direction and rotational spraying in the vertical direction, which greatly expands the spray atomization coverage range, eliminates spray dead angles and static blind spots, and forms a three-dimensional, scanning spray dust suppression network, which greatly improves the spray dust suppression effect.

[0050] During the spraying process, when the spray nozzle 14 becomes blocked or in a cold environment, the water in the water distribution cylinder 10 cannot be sprayed out of the spray nozzle 14 in time, causing the water level in the water distribution cylinder 10 to rise and push the moving ring 91 to move upward. The upward movement of the moving ring 91 drives the toothed plate 92 to move upward as well, and drives the gear 94, the rotating shaft 93 and the elliptical disk 95 to rotate. During the rotation of the elliptical disk 95, it reciprocates to squeeze the drive plates 98 on both sides. The drive plates 98 are pressed and drive the cleaning plate 962 and the cleaning ring 961 to move back and forth, performing cleaning and anti-clogging operations on the spray nozzle 14 and the water spray pipe 11.

[0051] Meanwhile, since the water spray pipe 11 rotates slowly and continuously during use, it can further improve the cleaning effect of the cleaning plate 962 and the cleaning ring 961. When the cleaning ring 961 cleans the spray hole 14, the air nozzle 13 is also blocked by the cleaning ring 961, which reduces the gas flow rate from the air supply pipe 12 and increases the gas flow rate from the impeller 84, thereby increasing the speed of the impeller 84 and accelerating the speed of the water spray pipe 11. This is beneficial for the cleaning and anti-clogging operation of the cleaning ring 961 and the cleaning plate 962 on the spray hole 14, ensuring unobstructed flow of the spray hole 14. After normal spraying operation, the water level in the water distribution cylinder 10 stops rising and returns to its original position. The moving ring 91 resets under the elasticity of the second spring 910 and drives the elliptical disk 95 and the drive plate 98 to reset. Thus, when the spray hole 14 is blocked, the rising liquid level in the water distribution cylinder 10 automatically drives the disk to rotate, thereby driving the cleaning plate 962 and the cleaning ring 961 to perform self-cleaning and anti-blocking operation on the spray hole 14. This not only effectively prevents the spray hole 14 from being blocked and ensures a long-term stable spraying effect, but also greatly reduces the labor intensity of manual inspection and cleaning.
