[0002] Construction air dust removal is an operation to reduce dust in the air during construction. It needs to be carried out in areas where dust is generated during construction to reduce dust in the air, improve the construction environment, and ensure the normal progress of construction.

[0003] Patent application CN202122763877.4 discloses a novel air dust removal device for environmental protection engineering construction, including a baffle plate. A base is threaded onto the top surface of the baffle plate. A positioning screw is fixedly installed in the middle of the bottom surface of the base. The bottom end of the positioning screw penetrates the top surface of the baffle plate and extends into the interior of the baffle plate. An insert rod is fixedly installed in the middle of the bottom surface of the inner cavity of the base. A sleeve block is movably sleeved inside the base. Spring cavities are opened at both ends of the middle of the inner cavity of the sleeve block.

[0004] However, during the dust removal process, the air dust removal devices used in environmental engineering construction often clog the nozzles due to incomplete atomization and residual liquid, which hinders the atomized liquid from being sprayed out. This reduces the atomization dust reduction effect, and the atomization effect of the clogged nozzles becomes worse. The concentration of uncaptured dust increases, making it easier for dust to be adsorbed by the un-atomized liquid and deposited near the nozzle, forming a hardened layer and exacerbating the nozzle clogging.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: an air dust removal device for environmental protection engineering construction, including a base 1, an adjustment frame 101 rotatably connected to the top of the base 1 via a bearing, a protective sleeve 102 rotatably connected to the inner wall of the adjustment frame 101 via a rotating shaft, and a flow guiding mechanism 2 provided inside the protective sleeve 102.

[0033] During the dust removal process, the air dust removal device used in environmental engineering construction often clogs the nozzle due to incomplete atomization and residual liquid, which hinders the atomized liquid from being sprayed out, resulting in a reduced atomization dust reduction effect. Therefore, a flow guiding mechanism 2 is set up to screen and distinguish the diameter of the atomized particles and output atomized particles with different diameters to increase the dust reduction coverage of the atomized gas.

[0034] The flow guiding mechanism 2 includes;

[0035] A flow guide sleeve 201 is fixedly connected to the inner wall of a protective sleeve 102. A flow guide groove 203 is formed on the outer wall of the flow guide sleeve 201. A flow guide plate 205 is fixedly connected to the outer wall of the flow guide sleeve 201, and its outer wall is connected to the inner wall of the protective sleeve 102. A connection hole 204 is formed on the outer wall of the flow guide sleeve 201. The flow guide groove 203 is a trapezoid with a gradually changing cross-section, used to guide the atomized condensate. The flow guide plate 205 is also used to guide the atomized condensate. The base 1 stores the liquid to be atomized and atomizes the liquid using an atomizing generator. Simultaneously, the base 1... The unit is equipped with a pump to deliver atomized gas to the inlet pipe 206, and then through the inlet pipe 206 to the guide sleeve 201 for screening and output. When the air dust removal device used in environmental protection engineering construction is put into use, the air dust removal device is placed in a suitable position, the atomizing generator inside the base 1 is activated to atomize the liquid to be atomized stored inside the base 1, and the pump inside the base 1 is activated to deliver the atomized gas to the inlet pipe 206, and then through the inlet pipe 206 to the guide sleeve 201. The motor 202 is activated to drive the central rod 207 to move in the guide sleeve. The inner wall of the flow sleeve 201 rotates, causing the central rod 207 to drive the guide fan 208 to rotate within the flow sleeve 201, guiding the atomized gas. The atomized gas is agitated by the centrifugal force generated by the rotation of the guide fan 208, and is filtered according to the size of the atomized gas particles during the agitation process. Smaller diameter atomized gas particles are lighter and are filtered by the guide fan 208 and then guided through the guide hole 212 for output. Larger diameter atomized gas particles are agitated by the centrifugal force generated by the guide fan 208 and are guided through the connection hole 204 into the outer wall of the flow sleeve 201, passing through the guide plate 20. After being guided, the liquid is output through the protective sleeve 102. At the same time, the atomized condensate captured by the guide fan 208 and condensed on the outer wall of the guide fan 208 is guided into the connecting hole 204 through the guide fan 208, and then guided to the outer wall of the guide sleeve 201 through the connecting hole 204. The atomized condensate flows along the outer wall of the guide sleeve 201 and is guided into the guide groove 203 through the guide plate 205. The atomized condensate is guided by the trapezoidal shape of the guide groove 203 with a gradually changing cross section, so that the atomized condensate is carried up by the airflow again through the guide groove 203 and output into the air through the protective sleeve 102 for dust suppression.

[0036] An air inlet pipe 206 is fixedly connected inside the guide sleeve 201. A motor 202 is fixedly connected to the outer wall of the guide sleeve 201. A central rod 207 is rotatably connected to the inner wall of the guide sleeve 201 via a bearing. A guide fan 208 is formed on the outer wall of the central rod 207. A guide hole 212 is formed on the inner wall of the guide sleeve 201. A limit groove 211 is formed on the outer wall of the guide sleeve 201. A support rod 209 is fixedly connected to the end of the central rod 207 away from the guide fan 208. A rotating shaft is rotatably connected to the inner wall of the support rod 209. The cleaning wheel 210 and the output end of the motor 202 are fixedly connected to the end of the central rod 207 near the motor 202. The guide fan 208 is used to filter and guide the atomized gas. The end of the air inlet pipe 206 away from the guide sleeve 201 is fixedly connected to the inside of the base 1. The atomized gas delivered to the inside of the guide sleeve 201 is driven by the motor 202 to rotate the central rod 207 on the inner wall of the guide sleeve 201, so that the central rod 207 drives the guide fan 208 to rotate inside the guide sleeve 201, guiding the atomized gas. The centrifugal force generated by the rotation of the guide fan 208 agitates the atomized gas and filters it according to particle size during the agitation process. Smaller diameter atomized particles, being lighter, are filtered by the guide fan 208 and then guided through the guide hole 212 before being output. Larger diameter atomized particles, agitated by the centrifugal force generated by the guide fan 208, are guided through the connection hole 204 into the outer wall of the guide sleeve 201, then guided by the guide plate 205 and output through the protective sleeve 102. Simultaneously, they are also filtered by the guide fan 208. 08 The atomized condensate captured on the outer wall of the guide fan 208 is guided into the connecting hole 204 through the guide fan 208, and then guided to the outer wall of the guide sleeve 201 through the connecting hole 204. The atomized condensate flows along the outer wall of the guide sleeve 201 and is guided into the guide groove 203 through the guide plate 205. The atomized condensate is guided by the trapezoidal shape of the guide groove 203 with a gradually changing cross section, so that the atomized condensate is carried up by the airflow again through the guide groove 203 and output to the air through the protective sleeve 102 for dust suppression.

[0037] Example 2, based on Example 1, please refer to... Figure 6 The present invention provides a technical solution: an atomizing component 3 is provided on the outer wall of the flow guide sleeve 201;

[0038] The atomized particles after screening have a small coverage area. Therefore, atomization component 3 is set up to further break down the atomized particles with larger diameters after screening, thereby reducing the diameter of the atomized particles and increasing the coverage area of ​​the atomized gas.

[0039] The atomizing component 3 includes a support sleeve 301, the outer wall of which is fixedly connected to the inner wall of the protective sleeve 102. A second support rod 302 is fixedly connected to the inner wall of the support sleeve 301. A roller 303 is rotatably connected to the inner wall of the second support rod 302 via a rotating shaft. A breaking rod 304 is fixedly connected to the inner wall of the roller 303. A second guide fan 305 is provided inside the support sleeve 301. The inner wall of the second guide fan 305 is rotatably connected to the wall of the first limiting groove 211 via a bearing. During the output of atomized gas through the protective sleeve 102, the second guide fan 305 rotates within the first limiting groove 211 driven by airflow, thus atomizing the gas. Further guiding the flow agitates the atomized gas, and during the rotation, the roller 303 contacts the outer wall of the second guide fan 305, and the roller 303 is driven to roll along the outer wall of the second guide fan 305 by friction. At the same time, as the roller 303 rotates on the inner wall of the second support rod 302, the larger diameter atomized gas particles guided by the guide plate 205 and the atomized gas liquid blown up by the airflow guided by the guide groove 203 are broken by the crushing rod 304 during the output process, reducing the diameter of the atomized gas and increasing the coverage of the atomized gas output through the protective sleeve 102.

[0040] The second guide fan 305 rotates within the first limiting groove 211, driven by the flow of atomized gas within the protective sleeve 102, thus guiding the atomized gas. The outer wall of the roller 303 contacts the outer wall of the second guide fan 305 and rolls along its outer wall through friction. The crushing rod 304 crushes the atomized condensate through the rotation of the roller 303. As the atomized gas exits through the protective sleeve 102, the second guide fan 305 rotates within the first limiting groove 211, driven by the airflow, further guiding the atomized gas. The atomized gas is stirred, and during the rotation, the roller 303 contacts the outer wall of the guide fan 2 305. Through friction, the roller 303 is driven to roll along the outer wall of the guide fan 2 305. This causes the larger diameter atomized gas particles guided by the guide plate 205 and the atomized gas liquid blown up by the airflow guided by the guide groove 203 to be broken by the crushing rod 304 during the output process, reducing the diameter of the atomized gas and increasing the coverage of the atomized gas output through the protective sleeve 102.

[0041] Example 3, based on Examples 1 and 2, please refer to... Figures 7-9 The present invention provides a technical solution: an output component 4 is provided on the inner wall of the flow guide sleeve 201;

[0042] The atomized condensate adhering to the nozzle 411 will adsorb the atomized gas particles, resulting in a reduction in the output efficiency of the atomized gas particles. Therefore, the output component 4 is set to guide the atomized gas and blow the atomized condensate out of the nozzle 411 by retracting compressed gas.

[0043] Output component 4 includes a guide block 401, the outer wall of which is fixedly connected to the inner wall of the guide sleeve 201. A second guide hole 402 is formed on the outer wall of the guide block 401, and a second limiting groove 403 is formed on the wall of the second guide hole 402. The second guide hole 402 is used to guide the atomized gas. Smaller atomized gas particles are guided by the first guide hole 212, buffered within the guide sleeve 201, and then guided through the second guide hole 402 on the outer wall of the guide block 401. They then enter the second guide hole 402 and, through the third connecting hole 414, enter the nozzle 411 for output. When the atomized gas condenses inside the nozzle 411, forming an atomized condensate that adheres to the inner wall of the nozzle 411, the central rod 207 drives the first support rod 209 to rotate. Simultaneously, the cleaning wheel 210 contacts the outer wall of the guide block 401, causing the cleaning wheel 210 to rotate along the guide through the first support rod 209. The outer wall of the flow block 401 rolls. When the cleaning wheel 210 rolls along the outer wall of the flow block 401 to the nozzle 411, the outer wall of the cleaning wheel 210 contacts the outer wall of the nozzle 411, squeezing the nozzle 411. This causes the nozzle 411 compression spring 412 to slide and retract on the inner wall of the second flow hole 402. During the retraction process, the flow limiting plate 415 slides on the inner wall of the second flow hole 402. At the same time, the limiting groove 403 guides the limiting block 416, causing the limiting block 416 to drive the flow limiting plate 415 to close the third connection hole 414, stopping the output of atomized gas. Meanwhile, as the nozzle 411 slides in the second flow hole 402, the outer wall of the nozzle 411 squeezes the air in the second flow hole 402, causing the air to enter the nozzle 411 through the second connection hole 413, blowing out the atomized condensate attached inside the nozzle 411 and preventing the atomized condensate from clogging the nozzle 411.

[0044] A spray assembly 41 is installed inside the second guide hole 402. The spray assembly 41 includes a nozzle 411. The outer wall of the nozzle 411 is slidably connected to the inner wall of the second guide hole 402 via a limiting slider. A spring 412 is fixedly connected to the outer wall of the nozzle 411, and the other end of the spring 412 is fixedly connected to the wall of the second guide hole 402. A second connection hole 413 is opened on the outer wall of the nozzle 411, and a third connection hole 414 is opened on the inner wall of the nozzle 411. The inner wall of the nozzle 411 is connected to the limiting slider via a bearing. The outer wall of the flow plate 415 is rotatably connected, and the outer wall of the flow limiting plate 415 is fixedly connected to the limiting block 416. The outer wall of the limiting block 416 is slidably connected to the groove wall of the limiting groove 403. The atomized gas is guided into the nozzle 411 through the connecting hole 414 and output through the nozzle 411. When the atomized gas condenses inside the nozzle 411, it forms an atomized condensate that adheres to the inner wall of the nozzle 411. The central rod 207 drives the support rod 209 to rotate, while the cleaning wheel 210 and the support rod 209 rotate simultaneously. The outer wall of the guide block 401 contacts the cleaning wheel 210, causing it to roll along the outer wall of the guide block 401 via the support rod 209. When the cleaning wheel 210 rolls along the outer wall of the guide block 401 to the nozzle 411, its outer wall contacts the outer wall of the nozzle 411, squeezing the nozzle 411. This causes the nozzle 411 compression spring 412 to slide and retract on the inner wall of the guide hole 402, and during the retraction process, it drives the flow limiting plate 415 to retract on the inner wall of the guide hole 402. 02 The inner wall slides, and at the same time, the limiting block 416 is guided by the limiting groove 2 403, so that the limiting block 416 drives the flow limiting plate 415 to close the connecting hole 3 414 and stop the output of atomizing gas. At the same time, as the nozzle 411 slides in the guide hole 2 402, the outer wall of the nozzle 411 compresses the air in the guide hole 2 402, so that the air enters the nozzle 411 through the connecting hole 2 413 and blows out the atomized condensate attached inside the nozzle 411.

[0045] The outer wall of the cleaning wheel 210 contacts the outer wall of the guide block 401 and rolls along the outer wall of the guide block 401 through friction. When the cleaning wheel 210 rolls to the nozzle 411, the outer wall of the cleaning wheel 210 contacts the outer wall of the nozzle 411 and squeezes the nozzle 411, causing the nozzle 411 compression spring 412 to slide on the inner wall of the guide hole 402. The cleaning wheel 210 is used to clean the atomized condensate adhering to the outlet of the nozzle 411. The support rod 209 is driven to rotate through the center rod 207, which at the same time drives the cleaning wheel 210 to roll along the outer wall of the guide block 401. When the cleaning wheel 210 rolls along the outer wall of the guide block 401 to the nozzle 411, the outer wall of the cleaning wheel 210... Contacting the outer wall of nozzle 411, the nozzle 411 is squeezed, causing the nozzle 411 compression spring 412 to slide and retract on the inner wall of the second guide hole 402. During the retraction process, the flow limiting plate 415 slides on the inner wall of the second guide hole 402. At the same time, the limit block 416 is guided by the second limit groove 403, so that the limit block 416 drives the flow limiting plate 415 to close the third connection hole 414, stopping the output of atomizing gas. At the same time, as the nozzle 411 slides in the second guide hole 402, the outer wall of the nozzle 411 squeezes the air in the second guide hole 402, so that the air enters the nozzle 411 through the second connection hole 413, blowing out the atomized condensate attached inside the nozzle 411.

[0046] As nozzle 411 slides within guide hole 2 402, limit block 416 guides flow limiting plate 415 to rotate on the inner wall of nozzle 411 via limit groove 2 403. During the rotation of flow limiting plate 415 on the outer wall of nozzle 411, connection hole 3 414 is closed. As nozzle 411 slides within guide hole 2 402, the gas stored in the gap between nozzle 411 and guide hole 2 402 is guided into nozzle 411 through connection hole 2 413, blowing out residual atomized condensate inside nozzle 411. The outer wall of cleaning wheel 210 contacts the outer wall of nozzle 411, compressing nozzle 411. The nozzle 411 compresses the spring 412, causing it to slide and retract on the inner wall of the second guide hole 402. During the retraction process, the flow limiting plate 415 slides on the inner wall of the second guide hole 402. At the same time, the limiting block 416 is guided by the limiting groove 403, causing the limiting block 416 to drive the flow limiting plate 415 to close the third connection hole 414, stopping the output of atomizing gas. Meanwhile, as the nozzle 411 slides in the second guide hole 402, the outer wall of the nozzle 411 compresses the air in the second guide hole 402, causing the air to enter the nozzle 411 through the second connection hole 413, blowing out the atomized condensate attached inside the nozzle 411.
