[0017] The principles and features of the present invention will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of the present invention.

[0018] Please refer to Figure 1-7 , as shown in the figure, a building environmental protection construction dust removal device provided in this embodiment, as Figure 1 shown, includes an air inlet and outlet pipeline 1. Specifically, the air inlet and outlet pipeline 1 is used to connect the air inlet and outlet pipelines 1 of air extraction or exhaust equipment, and the air extraction or exhaust equipment is used for construction dust removal. One end of the air inlet and outlet pipeline 1 is installed with a dust and debris inlet and outlet pipeline mechanism 2. A plurality of electrostatic adsorption mechanisms 5 are installed on the outer wall of the dust and debris inlet and outlet pipeline mechanism 2. One end of the dust and debris inlet and outlet pipeline mechanism 2 away from the air inlet and outlet pipeline 1 is installed with a cover mechanism 4; wherein the dust and debris inlet and outlet pipeline mechanism 2 includes a double-cylinder support seat 24. One end of the double-cylinder support seat 24 is used to communicate with the air inlet and outlet pipeline 1. The top of the double-cylinder support seat 24 includes an outer bearing part and an inner bearing part. The top of the outer bearing part of the double-cylinder support seat 24 is installed with a first bearing part 25. The top of the outer bearing part is rotatably connected with a first support cylinder section 27 through the first bearing part 25. The top of the inner bearing part of the double-cylinder support seat 24 is installed with a second bearing part 26. The top of the inner bearing part is rotatably connected with a second support cylinder section 28 through the second bearing part 26. The top of the first support cylinder section 27 is fixedly installed with an outer cylinder section 29; a plurality of groups of spiral fan blades 210 for facing the wind are installed in the inner cavity of the second support cylinder section 28. A plurality of groups of electrostatic friction rings 212 are fixedly installed on the outer wall of the second support cylinder section 28. The electrostatic adsorption mechanism 5 is installed inside the outer cylinder section 29. The electrostatic adsorption mechanism 5 includes an electrostatic friction rope 55. When the electrostatic friction rope 55 rubs against the electrostatic friction ring 212, an electrostatic adsorption state is formed.

[0019] Regarding the spiral fan blade 210, it should be noted that by designing the double-barrel support base 24, the second support cylinder section 28 and the outer cylinder section 29 can rotate to form an air flow. Combining with the windward effect of the spiral fan blade 210, the dust removal efficiency is effectively improved. During the rotation of the air flow, the spiral fan blade 210 can better capture and remove dust particles in the air, achieving a more efficient dust removal effect; the second support cylinder section 28 and the outer cylinder section 29 supported by the double-barrel support base 24 rotate to form an air flow. Combining with the windward effect of the spiral fan blade 210, the classified dust removal efficiency is improved. The air flow captures and removes dust particles in the air during rotation. At the same time, the static friction ring 212 and the static friction rope 55 generate static electricity by friction, adsorbing fiber materials to achieve classified dust removal.

[0020] Among them, a connecting pipe section two 23 is installed at the bottom of the double-barrel support base 24 in a communicating state. The bottom of the connecting pipe section two 23 is fixedly installed with a connecting pipe section one 22. The bottom of the connecting pipe section one 22 is fixedly installed with an air pipe connecting bolt 21 for connecting the air inlet and outlet pipe 1.

[0021] Furthermore, a plurality of prefabricated longitudinal grooves 211 are formed through the outer wall of the outer cylinder section 29, and the plurality of prefabricated longitudinal grooves 211 are arranged in a circular distribution; as Figure 6 shown, the prefabricated longitudinal groove 211 includes a longitudinal straight groove and a circular card slot. A plurality of circular card slots are formed in each longitudinal straight groove, and the circular card slots are used for installing the electrostatic adsorption mechanism 5.

[0022] Specifically, a transmission mechanism 3 is installed between the first support cylinder section 27 and the second support cylinder section 28. The transmission mechanism 3 includes a bearing part three 31. The bearing part three 31 is installed at the bottom of the inner cavity of the double-barrel support base 24. The bottom of the inner cavity of the double-barrel support base 24 is rotationally connected with a support roller shaft 32 through the bearing part three 31. The top of the support roller shaft 32 is fixedly installed with a gear block 33 through bolts; a gear groove one 34 is formed on the outer wall of the bottom of the second support cylinder section 28, and a gear groove two 35 is formed on the inner wall of the first support cylinder section 27. The gear block 33, the gear groove one 34 and the gear groove two 35 are meshed with each other.

[0023] In the construction dust removal device of the present invention, a transmission mechanism 3 is installed between the first support cylinder section 27 and the second support cylinder section 28. The support roller shaft 32 is rotationally connected through the bearing part three 31. The gear block 33 is fixedly installed at the top of the support roller shaft 32 through bolts. The gear block 33 is meshed with the gear groove one 34 of the second support cylinder section 28 and the gear groove two 35 of the first support cylinder section 27 to achieve linkage rotation, enhance the air flow effect and improve the dust removal efficiency.

[0024] Further, the cover body mechanism 4 includes a first cover body section 41. The first cover body section 41 is mounted on the top of the second support cylinder section 28 by bolts. A second cover body section 42 is mounted on the top of the first cover body section 41 by bolts. The second cover body section 42 is arranged in a flared shape, and the diameter of the top opening of the second cover body section 42 is larger than the diameter of the outer cylinder section 29. An air inlet / outlet groove 43 is formed in the middle of the first cover body section 41 and the second cover body section 42, and the air inlet / outlet groove 43 communicates with the second support cylinder section 28.

[0025] Further, an annular support seat 44 is fixedly mounted on the outer wall of the second cover body section 42. A fourth bearing member 45 is mounted at the bottom of the support seat 44. The support seat 44 is mounted on the top of the outer cylinder section 29 through the fourth bearing member 45.

[0026] Specifically, the electrostatic adsorption mechanism 5 includes a positioning cylinder 51. A hollow groove 52 is formed inside the positioning cylinder 51. A rope section positioning tube 54 is fixedly mounted at one end of the inner cavity of the hollow groove 52. The electrostatic friction rope 55 is fixedly mounted in the inner cavity of the hollow groove 52 through the rope section positioning tube 54. Positioning panels 53 are mounted at both ends of the positioning cylinder 51 by bolts. The positioning cylinder 51 is clamped in the circular clamping groove of the prefabricated longitudinal groove 211 through the two positioning panels 53.

[0027] It can be understood that during actual use, first, the air inlet / outlet pipe 1 is connected to one end of the first connecting pipe section 22 through the air pipe connecting bolt 21. The end of the air inlet / outlet pipe 1 away from the dust inlet / outlet pipe mechanism 2 is connected to the air extraction or exhaust device. Immediately afterwards, the second support cylinder section 28 and the outer cylinder section 29 are connected to one ends of the first connecting pipe section 22 and the second connecting pipe section 23. The dust floating in the air at the construction site can be removed through the air inlet / outlet of the air extraction or exhaust device.

[0028] During the process of air intake and exhaust, since the second support cylinder section 28 and the outer cylinder section 29 can rotate with the double-cylinder support seat 24 as the support point, when the air flow passes through the spiral fan blade 210, the second support cylinder section 28 will form a rotating state. When the second support cylinder section 28 rotates, the second support cylinder section 28 drives the gear block 33 to rotate through the first gear groove 34. When the gear block 33 rotates, it will drive the outer cylinder section 29 to reverse through the second gear groove 35, so that the second support cylinder section 28 and the outer cylinder section 29 form a forward and reverse rotation state. At this time, the static friction rope 55 will swing due to inertia. When the static friction rope 55 reciprocally rubs against the static friction ring 212, static electricity will be generated. In this way, fibrous materials can be adsorbed on the surface of the static friction rope 55 by static electricity, and flying dust materials can be directly washed away or directly sucked away. Because fibrous materials are lighter in mass, compared with dust, floating fibrous materials are more harmful to the human body on the one hand, and on the other hand, fibrous materials are very easy to block the dust extraction equipment. Therefore, through this solution, the state of electrostatic adsorption and the effect of classified dust removal are achieved. Finally, by rubbing the outside of the outer cylinder section 29 by hand, the fibrous dust on the surface of the static friction rope 55 can fall off;

[0029] In addition, it should be noted that the structures of the first bearing part 25, the second bearing part 26, the third bearing part 31, and the fourth bearing part 45 are not detailed in the attached drawings of the specification in this solution. The bearings can adopt sealed bearings, pedestal bearings, etc. in the prior art, and are only used to express the specific installation positions of the bearing parts in the attached drawings of the specification.

[0030] The technical effects and advantages of the present invention:

[0031] The traditional dust removal head design is prone to causing fibrous materials to adhere to the handle, affecting the dust removal efficiency. The present invention installs a static friction ring 212 on the second support cylinder section 28 and the outer cylinder section 29, and generates static electricity through friction with the static friction rope 55, so that fibrous materials can be effectively adsorbed, preventing them from blocking the dust extraction equipment or winding around the key parts of the dust removal device, and ensuring the continuous and efficient operation of the equipment;

[0032] The traditional construction dust removal device usually adopts a single pipe section design, which is prone to being blocked or wound at the end by fibrous materials, resulting in low dust removal efficiency. The present invention designs a double-cylinder support seat 24, enabling the second support cylinder section 28 and the outer cylinder section 29 to rotate to form an air flow. Combining with the windward effect of the spiral fan blade 210, the dust removal efficiency is effectively improved. The air flow can better capture and remove dust in the air through the spiral fan blade 210 during the rotation process, achieving a more efficient dust removal effect;

[0033] When traditional dust removal equipment deals with mixed dust and debris, it is difficult to effectively distinguish fibrous materials from dust, which easily leads to equipment blockage. In this invention, through electrostatic adsorption technology, fibrous materials are adsorbed on the surface of the electrostatic friction rope 55, while the heavier dust is directly washed away or sucked away by the airflow. This not only effectively realizes classified dust removal, improves the dust removal efficiency, but also protects the normal operation of the equipment and reduces the maintenance frequency;

[0034] The design of this invention has high flexibility and adaptability. By replacing or adjusting the materials or structures of the electrostatic friction ring 212 and the electrostatic friction rope 55, it can adapt to different dust removal requirements. For example, materials more suitable for adsorbing specific types of dust debris can be selected, so that it can be widely applied in various construction environments, significantly enhancing the practical value and market competitiveness of the equipment.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
