Description

Technical Field

[0001] The present invention belongs to the technical field of dust removal equipment, and particularly relates to a dust removal device and method for building construction. Background Art

[0002] Building engineering refers to the work of constructing, reconstructing or demolishing infrastructure and buildings on or under the ground according to certain requirements by means of engineering construction methods and engineering technologies. During the construction of building engineering, a large amount of dust and waste gas will be generated, which will cause harm to the surrounding environment and construction workers. Therefore, it is very important to adopt a reasonable dust removal device for building engineering construction.

[0003] Although there are various dust removal devices at present, there are still some problems. For example, in the current dust removal devices that carry out dust removal operations by spraying water mist, most of the fog guns used for spraying water mist are fixed and supported by a supporting device. When spraying water mist, the spraying angle of the fog gun is often fixed, which results in a small range of the water mist sprayed by the fog gun. In order to expand the range of the fog and improve the dust removal effect, it is necessary to adjust the angle of the supporting device. However, the existing supporting structures mostly adopt split hinge or slide rail designs, and can only achieve angle adjustment in a single direction (up and down or left and right). For example, for up and down adjustment, the vertical shaft needs to be fixed by bolts, and for left and right adjustment, it depends on a horizontal turntable. The two lack a linkage device, and each angle adjustment requires separate operation of two independent mechanisms, increasing the average time consumption. For example, when turning from horizontal to an inclined angle, it is necessary to first loosen the upper and lower locking bolts to adjust the pitch angle, and then rotate the horizontal turntable to adjust the azimuth angle, resulting in an extended interruption time of the dust removal operation. At the same time, step-by-step adjustment easily causes an angle between the spray direction and the airflow field of the dust removal system (such as the tangential air inlet path of a cyclone dust collector), reducing the coagulation efficiency of aerosol particles. Summary of the Invention

[0004] The present invention provides a dust removal device and method for building construction, aiming to solve the problems that the current dust removal device can only adjust the angle in a single way, cannot adjust synchronously in multiple directions, and is time-consuming and laborious during adjustment, affecting the dust removal efficiency.

[0016] 2. At the same time, use the convex block to push the second support rod to slide up and down, and then drive the supporting rod to rotate on the first support rod, so that the vertical angle of the dust removal spray mechanism is synchronously changed and reciprocated, so as to maximize the dust removal range of the dust removal spray mechanism, and can be linked synchronously in the horizontal and vertical directions, avoiding the problem that the spray direction forms an angle with the airflow field of the dust removal system (such as the tangential inlet path of a cyclone dust collector) due to step-by-step adjustment, reducing the problem of the aggregation efficiency of aerosol particles. And a self-locking structure is formed by the combination of the worm gear and the worm, so that the angle of the dust removal spray mechanism can be arbitrarily locked at a certain place, which is simple, efficient and practical.

[0020] In a first aspect, an embodiment of the present invention provides a building construction dust removal device, as Figures 1-6 shown, including: a base 1, a fixed rod 2, a dust removal spray mechanism 3, a tray 4, a horizontal angle adjustment mechanism 5, and a vertical angle adjustment mechanism 6. An installation cavity is provided inside the cylindrical base 1. The fixed rod 2 is fixed at the center of the base 1. The dust removal spray mechanism 3 is arranged at the top of the fixed rod 2. The tray 4 is coaxially rotatably connected to the fixed rod 2 and is located at the bottom of the installation cavity. The horizontal angle adjustment mechanism 5 and the vertical angle adjustment mechanism 6 are both arranged on the tray 4; The dust removal spray mechanism 3 includes a first support rod 31, a supporting rod 32, and an atomizing nozzle 33. The first support rod 31 is coaxially and rotatably connected to the top end of the fixed rod 2. The supporting rod 32 is rotatably connected to the top end of the first support rod 31. The atomizing nozzle 33 is arranged at one end of the supporting rod 32. The horizontal angle adjustment mechanism 5 includes a first fixing bracket 51, a transmission rod 52, a linkage disk 53, and a limit seat 54. The first fixing bracket 51 is fixed on the tray 4. The transmission rod 52 is rotatably connected to the first fixing bracket 51. The linkage disk 53 is fixed on the transmission rod 52. The limit seat 54 is fixed on the tray 4 and is located on one side of the transmission rod 52. The horizontal angle adjustment mechanism 5 further includes a gear 55 and a rack 56. The gear 55 is coaxially fixed on the fixed rod 2. The rack 56 is slidably clamped in the limit seat 54, and the gear 55 meshes with one side of the rack 56. The horizontal angle adjustment mechanism 5 further includes a docking plate 57 and a limit groove 58. The docking plate 57 is fixed at one end of the rack 56. The limit groove 58 is concavely arranged at the edge of the linkage disk 53 and has a special-shaped structure. The end of the docking plate 57 away from the rack 56 is slidably clamped in the limit groove 58. The vertical angle adjustment mechanism 6 includes a second fixing bracket 61, a second support rod 62, and a convex block 63. The second fixing bracket 61 is fixed on the tray 4. The second support rod 62 is slidably connected to the second fixing bracket 61, and the top of the second support rod 62 is rotatably connected to the end of the first support rod 31 away from the atomizing nozzle 33. The convex block 63 is fixed on the transmission rod 52. The bottom of the second support rod 62 slidably abuts against the side wall of the convex block 63.

[0021] It should be noted that since most of the current dust removal devices can only be adjusted unidirectionally, for example, adjusted up and down or left and right, and it is impossible to synchronously link the two, and it takes a certain amount of time to adjust, which is not only cumbersome to operate but also seriously affects the dust removal efficiency. To solve this problem, in this solution, a dust removal spray mechanism 3, a horizontal angle adjustment mechanism 5, and a vertical angle adjustment mechanism 6 are provided. The atomizing nozzle 33 in the dust removal spray mechanism 3 sprays water mist to realize the dust removal operation. And during dust removal, the transmission rod 52 drives the linkage disk 53 and the convex block 63 to rotate synchronously, so that one end of the docking plate 57 slides in the limit groove 58, and drives the rack 56 to reciprocate. Through the meshing and linkage of the rack 56 and the gear 55, the whole tray 4 is driven to rotate on the fixed rod 2, so as to realize the rapid adjustment of the angle of the dust removal spray mechanism 3 in the horizontal direction. Meanwhile, the bump 63 is utilized to push the second support rod 62 to slide up and down, thereby driving the supporting rod 32 to rotate on the first support rod 31, causing the vertical angle of the dust removal spray mechanism 3 to change synchronously and reciprocate, thus maximizing the dust removal range of the dust removal spray mechanism 3 and enabling linkage in both the horizontal and vertical directions simultaneously, which is simple, efficient, and practical.

[0022] Specifically, in this embodiment, the solution mainly includes a base 1, a fixed rod 2, a dust removal spray mechanism 3, a tray 4, a horizontal angle adjustment mechanism 5, and a vertical angle adjustment mechanism 6. During use, first, one end of the diversion pipe 34 is connected to an external liquid storage device, and the liquid is introduced into the atomizing nozzle 33 to atomize and spray the liquid for dust removal operations. Then, the servo motor 67 is started, and the worm 65 is driven to rotate through the belt 68, thereby causing the worm gear 64 to engage and drive synchronously. At this time, the transmission rod 52 drives the linkage disk 53 to rotate synchronously. The docking plate 57 slides in the limiting groove 58 and drives the rack 56 to slide. Through the engagement of the rack 56 and the gear 55, the entire tray 4 is driven to rotate on the fixed rod 2, and the horizontal angle of the atomizing nozzle 33 is synchronously changed. When the transmission rod 52 rotates, it drives the bump 63 to rotate synchronously, and the second support rod 62 is driven to slide up and down through the bump 63. The supporting rod 32 is driven by the second support rod 62 to rotate on the first support rod 31, so that the vertical angle of the atomizing nozzle 33 can be changed synchronously.

[0023] In a further preferred embodiment of the present invention, as Figures 1-6 shown, the vertical angle adjustment mechanism 6 further includes a worm gear 64 and a worm 65. The worm gear 64 is coaxially fixed on the transmission rod 52, and the worm 65 is rotatably connected to the tray 4 and meshes with the worm gear 64.

[0024] In this embodiment, a self-locking structure is formed by the combination of the worm gear 64 and the worm 65, enabling the angle of the dust removal spray mechanism 3 to be arbitrarily locked at a certain position.

[0025] In a further preferred embodiment of the present invention, as Figures 1-6 shown, the vertical angle adjustment mechanism 6 further includes a driven disk 66, a servo motor 67, and a belt 68. The driven disk 66 is coaxially fixed at one end of the worm 65, the servo motor 67 is fixed on the tray 4, and the belt 68 is disposed between the driven disk 66 and the output shaft of the second servo motor 67.

[0026] In this embodiment, the driven disk 66 can be synchronously linked with the output shaft of the servo motor 67 through the belt 68, driving the worm 65 to rotate.

[0027] In a further preferred embodiment of the present invention, as Figures 1-6As shown, one end of the docking plate 57 close to the limiting groove 58 is rotatably connected with a first pulley 59. The first pulley 59 is rollingly clamped in the limiting groove 58, and a second pulley 69 is rotatably connected to the abutting end of the second support rod 62 and the convex block 63. The second pulley 69 is rollingly abutted against the convex block 63.

[0028] In this embodiment, through the rolling of the first pulley 59 and the second pulley 69, the wear of the docking plate 57 and the second support rod 62 is respectively reduced.

[0029] In a further preferred embodiment of the present invention, as Figures 1-6 shown, one end of the atomizing nozzle 33 is connected with a diversion pipe 34, and one end of the diversion pipe 34 is connected with an external liquid storage device.

[0030] In this embodiment, through the arrangement of the diversion pipe 34, the atomizing nozzle 33 can be quickly connected with the external liquid storage device.

[0031] In a further preferred embodiment of the present invention, as Figures 1-6 shown, a clamp 35 is fixed on the supporting rod 32. A plurality of clamps 35 are arranged at equal intervals, and the diversion pipe 34 is clamped in the clamp 35.

[0032] In this embodiment, the fixing effect on the diversion pipe 34 is achieved through the clamp 35.

[0033] In a further preferred embodiment of the present invention, as Figures 1-6 shown, a plurality of roller seats are arranged at the bottom edge of the installation cavity of the base 1, and rollers are rotatably connected to the roller seats, and the rollers are rollingly abutted against the tray 4.

[0034] In this embodiment, the edge of the tray 4 is supported by the roller seats and the rollers, so that the overall force on the tray 4 is uniform.

[0035] Second, referring to Figures 1-6 , the present application also provides a dust removal method, including the following steps: S1. Spray dust removal. First, connect one end of the diversion pipe 34 with an external liquid storage device, and introduce the liquid into the atomizing nozzle 33 to atomize and spray the liquid for dust removal operation; S2. Horizontal angle adjustment. Start the servo motor 67, drive the worm 65 to rotate through the belt 68, and then make the worm gear 64 meshing and linkage. At this time, the transmission rod 52 drives the linkage disc 53 to rotate synchronously. The docking plate 57 slides in the limiting groove 58 and drives the rack 56 to slide. Through the meshing of the rack 56 and the gear 55, the whole tray 4 is driven to rotate on the fixing rod 2, and the horizontal angle of the atomizing nozzle 33 is changed synchronously; S3. Vertical angle adjustment: When the transmission rod 52 rotates, it drives the convex block 63 to rotate synchronously, and drives the second support rod 62 to slide up and down through the convex block 63. The second support rod 62 drives the supporting rod 32 to rotate on the first support rod 31, so that the vertical angle of the atomizing nozzle 33 changes synchronously.
