[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figures 1 to 4 As shown, as an embodiment of a construction dust removal device, the construction dust removal device includes a support frame 10, an exhaust fan 20, a rotating body 30, a dust collection cylinder 40, a dust mixing box 50, and a control box 60. The exhaust fan 20 is located at the top of the support frame 10 and has a dust suction port for drawing in dust and a dust discharge port for conveying dust. Figure 2In the vertical direction, the rotating body 30 includes a first hollow rotating component 31 and a second hollow rotating component 32. Both the first hollow rotating component 31 and the second hollow rotating component 32 are annular structures. The first hollow rotating component 31 is arranged around the bottom of the exhaust fan 20 and is also rotatably connected to the second hollow rotating component 32, allowing the exhaust fan 20 to rotate freely in the circumferential direction relative to the second hollow rotating component 32. The dust collection cylinder 40 is fixed to the middle part of the bracket 10 and is used to collect dust. The top of the dust collection cylinder 40 is also fixedly connected to the second hollow rotating component 32 in the circumferential direction. The top of the dust collection cylinder 40 is provided with a dust collection port that communicates with the dust outlet, and the bottom of the dust collection cylinder 40 is provided with a discharge port. The dust mixing box 50 is fixed to the bottom of the dust collection cylinder 40. The dust mixing box 50 stores dust mixing liquid. The top of the dust mixing box 50 is provided with a feed port that communicates with the discharge port. The bottom of the dust mixing box 50 is also provided with a liquid outlet. The control box 60 is fixed to the dust mixing box 50 and is electrically connected to the exhaust fan 20.

[0022] In this embodiment, when the control box 60 controls the exhaust fan 20 to work, the exhaust fan 20 can suck up dust from the air through the suction port and transfer the dust to the dust collection cylinder 40 through the dust outlet; the rotating body 30 is arranged between the exhaust fan 20 and the dust collection cylinder 40, so that the exhaust fan 20 can rotate freely, thereby quickly and accurately adjusting the dust removal angle, so that the exhaust fan 20 can suck up dust from all directions; the dust collection cylinder 40 transports the collected dust to the dust mixing box 50, which stores a dust mixing liquid (e.g., clean water). The dust dissolves in the dust mixing liquid, and the dust and dust mixing liquid can form waste liquid that is discharged from the liquid outlet to prevent secondary dust pollution.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, in order to prevent large particles from damaging the exhaust fan 20 and to filter out large debris, the construction dust removal equipment also includes a filter screen 70. The filter screen 70 is installed at the dust inlet and has multiple filter holes 71. Dust can enter the exhaust fan 20 through the filter holes 71, but large particles and debris will be blocked in the filter holes 71 to prevent them from entering the exhaust fan 20 and causing malfunctions or damage to the exhaust fan 20.

[0024] Furthermore, to facilitate the control of the outflow of waste liquid, a drain valve is also installed at the outlet, which is controlled by the control box 60; when the control box 60 controls the drain valve to open, the waste liquid flows out.

[0025] Furthermore, in order to facilitate the diversion of waste liquid, the outlet of the dust collection box 50 is also connected to a drain pipe 510, through which the waste liquid can be discharged.

[0026] Furthermore, to facilitate the collection of waste liquid, the construction dust removal equipment also includes a waste liquid tank (not shown in the figure). The waste liquid tank is connected to the drain pipe 510, and the waste liquid can enter the waste liquid tank through the drain pipe 510 to avoid waste liquid pollution of the ground.

[0027] Furthermore, in order to facilitate the addition of mixing liquid to the dust mixing box 50, an inlet (not shown in the figure) is also provided on the side wall of the dust mixing box 50.

[0028] Furthermore, such as Figure 3 As shown, in order to facilitate the adjustment of the dust suction direction of the exhaust fan 20, the construction dust removal equipment also includes a mounting base 80 and a guide rudder 90. The mounting base 80 is fixed to the top of the exhaust fan 20, and the guide rudder 90 has a plate-like structure and is detachably connected to the mounting base 80. The guide rudder 90 can act on the exhaust fan 20 to freely adjust the dust suction direction of the exhaust fan 20.

[0029] Preferably, to fix the suction direction of the exhaust fan 20, a limiting member (not shown) is also provided on the dust collection cylinder 40. One end of the limiting member is movably connected to the dust collection cylinder 40, and the other end is detachably connected to the outer casing of the exhaust fan 20. When the suction direction of the exhaust fan 20 is adjusted, the limiting member is connected and fixed to the outer casing of the exhaust fan 20 to prevent the exhaust fan 20 from changing its suction direction due to wind force. Preferably, there are multiple limiting members, which are evenly distributed along the outer wall of the dust collection cylinder 40.

[0030] Furthermore, in order to facilitate the rapid flow of dust collected in the dust collection cylinder 40 to the dust mixing box 50, the overall shape of the dust collection cylinder 40 is conical, and the cross-sectional dimension of the dust collection cylinder 40 gradually decreases from the top to the bottom. Preferably, the cross-section of the dust collection cylinder 40 can be annular or hollow rectangular.

[0031] Furthermore, such as Figure 4 As shown, to ensure a more uniform mixing of dust and slurry, the construction dust removal equipment also includes a mixing assembly 100. The mixing assembly 100 includes a mixing motor 110, a rotating shaft 120, and mixing sections 130. The mixing motor 110 is fixed to the outside of the dust collection box 50 and is controlled by a control box 60. The rotating shaft of the mixing motor 110 passes through the dust collection box 50. One end of the rotating shaft 120 is fixedly connected to the rotating shaft, and the other end is movably connected to the dust collection box 50. Multiple mixing sections 130 are staggered along the axial direction of the rotating shaft 120, and each mixing section 130 is perpendicular to the rotating shaft 120. In this embodiment, when the control box 60 controls the mixing motor 110 to operate, the rotating shaft of the mixing motor 110 drives the mixing sections 130 to rotate via the rotating shaft 120, allowing the mixing sections 130 to fully mix the dust and slurry during the mixing process.

[0032] In this embodiment, the stirring unit 130 includes a stirring rod 131 and a stirring handle 132. The connecting end of the stirring rod 131 is detachably connected to the rotating shaft 120, which facilitates maintenance and replacement. The free end of the stirring rod 131 extends away from the rotating shaft 120. The stirring handle 132 has a sheet-like structure and is fixed to the free end of the stirring rod 131.

[0033] Furthermore, such as Figure 2 As shown, the support frame 10 includes multiple vertical support rods 11 and multiple horizontal connecting rods 12. The multiple vertical support rods 11 are arranged in a ring in the vertical direction, and the horizontal connecting rods 12 are disposed between two adjacent vertical support rods 11, thereby enhancing the stability between the multiple vertical support rods 11. The support frame 10 also includes anti-slip pads 13 disposed at the bottom of the vertical support rods 11 to increase the friction between the construction dust removal equipment and the ground and prevent slippage.

[0034] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0035] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0036] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
